Further No particular problem arises when operating data is periodic (for example once a day) from a construction machine to the administrator become; however, if data from multiple construction machines all on transferred at the same time become, the communication lines are overloaded, leading to possible disabilities how communication delays can lead.

It is therefore possible different transmission time data in each of the several construction machines. Here, however, must In each construction machine individually software be installed, which the different transmission time data contains. Consequently can Parts of several construction machines not standardized with each other and the total system costs increase.

It is therefore the object of the present invention, communication overload by varying the transmission times under several mobile bodies to avoid while the standardization of in the several mobile bodies too installed software.

Overview of the invention

The object of the invention is achieved by a method according to claim 1, in which:
each of the plurality of mobile bodies is provided with information collecting means for collecting information regarding the own mobile body; and
each of the plurality of mobile bodies measures a time at which a particular event occurs in the own mobile body, sets an individual automatic transmission time for itself using the measured time as a reference, and when the automatic transmission time is reached, by the Information collecting device transmits collected information from the own mobile body to the terminal device.

at a preferred embodiment the time measured to which the communication device which performs a communication with the terminal device, with Energy is supplied, and the automatic transmission time of the mobile body is set, taking the energy supply time of your own mobile body is used as a reference.

In the several vehicles 31 . 32 . 33 ... (please refer 1 ), a detection is performed whether a specific event is occurred in a vehicle, for example, that a communication terminal 56 (please refer 21 ), or, in other words, energy from an energy source 63 to the communication terminal 56 was created. The energy supply time is then measured by means of a calendar and a timer inside the vehicle. Subsequently, an individual automatic transmission time is set in each vehicle, using the power supply time of this vehicle as a reference.

More precisely, when the energy supply time of the vehicle 31 is assumed to be 9:32, a fixed period of twelve hours after the power supply time becomes 9:32 (21:32) as the automatic transmission time of the vehicle 31 set. Suppose the energy supply time of another vehicle 32 is 10:30, so will the automatic transmission time of the vehicle 32 set to 22:30; In this way, the automatic transmission times between the multiple vehicles can be varied.

In the vehicles 31 . 32 . 33 ... (please refer 1 ) detects that a motor key switch 64 (please refer 21 ) has been switched from On to Off in each vehicle. The time at which the key switch was turned off is measured by the calendar and the timer inside the vehicle. The last key switch off time or, in other words, the time at which the engine key switch 64 during a calendar day (0:00 to 24:00), is then saved as data. Using the last key switch off time as a reference, an individual automatic transmission time is set for each vehicle.

More specifically, when the time at which the engine key switch 64 in the vehicle 31 last turned off at 15:47, a fixed period of fifteen hours after the last key switch off time becomes 15:47 (6:47) as the vehicle's automatic transmission time 31 set. Suppose the last key switch off time of another vehicle 32 is 15:55, so is the automatic transmission time of the vehicle 32 is set to 6:55, and thus the automatic transmission times among the several vehicles can be varied.

According to a preferred embodiment, each of the plurality of mobile bodies is provided with:
an information collecting device for collecting information regarding the own mobile body; and
a random number generator, and wherein
each of the plurality of movable bodies sets an individual automatic transmission time by itself, and a random number generated by the random number generation means serves as a reference.

A software for automatically generating random numbers is in the multiple vehicles 31 . 32 . 33 ... (please refer 1 ) Installed. When this random number generation software is activated, a random number is generated and the individual automatic transmission time of each vehicle is set by using this generated random number as a reference.

Specifically, assume that the range of random number generation is set as ranging from "00" to "59", and that in the vehicle 31 generated random number "38" is such that a time (24:38) at which the generated random number "38" becomes the "minute unit" and a set numerical value "24" becomes the "hour unit" than the automatic transmission time of the vehicle 31 is set. Suppose that in another vehicle 32 generated random number is "55", then the automatic transmission time of the vehicle 32 24:55, so that the automatic transmission times among the several vehicles can be varied in this way.

According to a preferred embodiment, when the time of occurrence of a certain event (power supply time) in the vehicle 31 is assumed to be 9:32, a time (24:32) than the automatic transmission time of the vehicle 31 is set at which only the minute unit "32" of the power supply time 9:32 is extracted, and a preset numerical value "24" becomes the "hour unit". Suppose the energy supply time of another vehicle 32 is 10:30, so will the automatic transmission time of this vehicle 32 at 24:30, and thus the automatic transmission times among the plurality of vehicles can be varied while being limited to a time-window range of "24:00 (0:00 at night) to 1:00 (1:00 at night)".

27 shows a map screen from the website on the display device of the terminal 11 is shown. These map data are in the computer of the terminal 11 saved. As in 27 represented, icons (pictographic signs) representing each of the mobile body 31 to 35 specify transferred to the card and displayed. Because the types of mobile body 31 to 35 (Bulldozer, hydraulic excavator, wheel loader, semi-trailer, service vehicle) can be indicated by the icons, the mobile body 31 to 35 be easily distinguished. The positions of the icons on the map are from the GPS sensor 57 in each of the mobile bodies 31 to 35 detected and correspond to the last mobile body information stored in the database of the server terminal 21 are stored.

When an input operation (key operation, click or the like) for moving the website screen to the next screen in the row at the input device of the terminal 11 takes place, a sequential movement from the current screen to the next screen is performed. In this case, by clicking on the icon of the mobile body (for example, the mobile work machine 31 ), which is under the icons of the mobile body 31 to 35 to be displayed on the screen, a change to a screen is made showing detailed information which only the mobile work machine to be displayed 31 affect.

For example, shows 31 a screen displaying a list of information representing all mobile bodies 31 to 35 affect.

By clicking on the icon of the mobile body (for example, the mobile work machine 31 ), for which on the screen after 31 the display of detailed information is desired, followed by a change to the screen after 28 and the latest mobile body information, especially the mobile work machine 31 are displayed on the screen. On the screen, as in 28 displayed, displays detailed mobile body information for a particular mobile body can also be changed by performing a similar operation on the in 27 illustrated map screen for all mobile bodies 31 to 35 is carried out.

28 shows a screen displaying the latest data for a single machine type.

As in 28 Mobile body information regarding a particular mobile body (e.g., the mobile work machine) may be displayed 31 ), such as the current position, operating hours counter value, fuel quantity, engine speed, engine cooling water temperature, battery voltage, hydraulic pump discharge pressure, amount of oil, abnormality (error codes), and images captured by the camera. In the in 6 illustrated case, for example, in which the mobile work machine 31 Dredging on a mound 116 performs the state of dredging at the mound 116 from the camera 60 detected. As a result, as in the 28 pictured, a picture of the mound 116 on the screen of the terminal 11 displayed.

33 FIG. 12 is a flowchart showing a communication control processing sequence which will be described below with reference to the diagram. FIG.

If the named data in the request originating terminal 11 are input, request origin identification data D1 representing the request origin terminal (terminal 11 Request receiver identification data D2 representing the request receiver mobile body (the mobile work machine 31 ), identification information D3 on the requested information indicating the content of the requested information (vehicle position, fuel amount), and display receiver identification data D4 indicating the display receiver terminal (terminal 12 ) from the terminal 11 to the server terminal 21 transmitted as electronic mail, which consists of data which the communication protocol on the Internet 2 correspond. The request origin identification data D1 ("Terminal 11 ") correspond to the mail address of the request originating terminal 11 , The display receiver identification data D4 ("Terminal 12 ") correspond to the mail address of the display receiver terminal 12 , Furthermore, the request identification data D2 ("mobile work machine 31 ") the mail address of the mobile work machine 31 ,

The server terminal 21 receives the transmitted electronic mail and reads the request receiver identification data D2, and then stores the contents of the electronic mail in the mailbox of the mobile work machine 31 corresponding to the request receiver identification data D2 ("mobile work machine 31 ").

The server terminal (mail server) 21 transfers data to the mobile work machine 31 , whereby the retrieval of the electronic mail in the mailbox is requested. In particular, a response request signal is sent to the mobile work machine 31 from the communications satellite 9 over the wireless communication line 5 transfer. Whether the transmission of this response request signal from the side of the communication satellite 9 to the mobile work machine 31 is possible, is often unclear as the mobile work machine 31 may be in an environment unfavorable for communication, and so on, so transmission is continuous. Associated with this is the presence of a response request signal from the mobile work machine 31 out to the communications satellite 9 intermittently checked. The presence of a response request signal is checked by detecting radio waves indicating a response request signal and from the communication satellite 9 be transferred from. This check for the presence of a response request signal (detection of radio waves indicating a response request signal) is made at the time of a certain event or after elapse of a predetermined time after the occurrence of a certain event.

For example, a check for the presence of a response request signal may be made when the mobile work machine is being put into service 31 is detected, wherein the corresponding detection signal acts as a trigger. In this case, the check of the presence of a response request signal may be performed only when the engine is started for the first time in one day.

A check for the presence of a response request signal may also be made when the occurrence of an irregularity in the mobile work machine 31 is detected, wherein the corresponding detection signal acts as a trigger.

Further, a check may be made for the presence of a response request signal after a predetermined period of time after the last transmission by the mobile work machine 31 take place, after which the next transfer can be carried out.

This particular event or period may be modified as desired. Changes can be made by means of an input operation in the input device of the terminal 11 respectively.

When it is determined that there is a response request signal as a result of checking for the presence of a response request signal, the mobile work machine transmits 31 Data indicating the receipt of electronic mail in their mailbox to the server terminal 21 over the communications satellites 9 , As a result, will the electronic mail from the server terminal 21 to the mobile work machine 31 transfer.

In other words, the electronic mail is sent over the Internet 2 to the network control station 7 and the data in the electronic mail is converted in terms of the protocol. The electronic mail converted with regard to the protocol is then transmitted via the private line 3 transfer. The electronic mail is then transmitted via the satellite ground station 8th , the supply line 4 , the communications satellite 9 and the wireless communication line 5 to the mobile work machine 31 transmitted and from the satellite communication antenna 58 the mobile work machine 31 receive.

the communication terminal 56 the mobile work machine 31 reads out the requested information identification data D3 ("vehicle position", "fuel amount") from the electronic mail sent from the satellite communication antenna 58 has received and instructs the communication controller 54 on, from the mobile work machine 31 to obtain the mobile body information corresponding to the identification data D3 of the requested information, or in other words, the vehicle position data and the fuel amount data.

After receiving this command, the communication controller transmits 54 that from the GPS sensor 57 detected current vehicle Posi tion data to the communication terminal 56 , The "fuel quantity data", which is the electronic control 53 are written are written in a frame signal and over the signal line 52 transfer. The written content of the frame signal is from the electronic controller 53 read, whereupon detected data concerning the current amount of fuel from the sensor group 62 the electronic control 53 and written to the frame signal. The frame signal is then transmitted over the signal line 52 to the communication controller 54 transfer. The fuel data written in the frame signal is received from the communication controller 54 read and to the communication terminal 56 transfer. The vehicle position data and the fuel amount data are then converted into an electronic reply mail in the communication terminal 56 recorded as mobile body information data D3 '.

Request receiver identification data D2, which request receiver mobile body (the mobile work machine 31 ), response recipient identification data D4 representing the response receiver terminal (Terminal 12 ), and the mobile body information data D3 'indicating the mobile body information (vehicle position data and fuel quantity data) will read electronic answer mail consisting of data corresponding to a predetermined communication protocol from the communication terminal 56 via the satellite communication antenna 58 on the communications satellites 9 transfer. It should be noted that D1 and D3 are transmitted simultaneously. D1 can be used as a key to break down into the respective communication toll bill receivers. D3 serves to identify the content of D3 '. Here, the request recipient identification data D2 ("mobile work machine 31 ") the mail address of the mobile work machine 31 , The answer identification data D4 ("Terminal 12 ") correspond to the mail address of the display receiving terminal 12 ,

The electronic answer mail is from the communications satellite 9 received and over the supply line 4 , the satellite ground station 8th and the private line 3 to the network control station 7 transfer. The data in the electronic reply mail will be in the network control station 7 in terms of protocol, and the protocol's electronic response mail is converted over the Internet 2 transfer.

The server terminal 21 receives the transmitted electronic mail, performs the reply receiver identification data D4, and stores the contents of the electronic mail in the mailbox of the terminal 12 representing the response recipient identification data D4 ("Terminal 12 ").

Subsequently, the aforementioned mobile body information extraction program is performed such that the mobile body information data D3 '("vehicle position data", "fuel amount data") and the request receiver identification data D2 ("mobile work machine 31 ") from the contents of the mailbox of the terminal 12 stored electronic mail, whereupon the vehicle position data and the fuel quantity data corresponding to the address of the mobile work machine 31 get saved. In this way, the content of all the mobile body information data MD is updated.

The server terminal (mail server) 21 transfers data to the terminal 12 , whereby the retrieval of the electronic mail in the mailbox is requested. After receiving this request, the terminal transmits 12 Data to the server terminal 21 indicating that the electronic mail is received in the mailbox. In this way, the electronic mail from the server terminal 21 to the terminal 12 transfer. The data to be transferred can be restricted depending on the security level of D4.

When the electronic mail from the terminal 12 on the server side of the transport 35 for mobile work machines, the request receiver identification data D2 (mobile work machine 31 ) and the mobile body information data D3 '(vehicle position data and fuel quantity data) are read from the data in the electronic mail. The content of the electronic mail, that is the current position and the current amount of fuel of the mobile work machine 31 , then appears on a screen of the terminal 12 displayed.

Based on the screen display of the terminal 12 is the operator of the transport vehicle 35 capable of the specific work machine 31 to recognize which is provided by the administrator for transportation, and he can also learn the current position and the current amount of fuel of the same, which for the Tramsport the mobile machine 31 required are. Further, the operator is at the terminal 12 able to leave the screen of the terminal 12 only gain information required for the operation without performing an information request input operation. In other words, even if an operator who wants to obtain information is in a situation where there is no input to the terminal 12 can be done, the information necessary for the operation can be obtained. As a result, a transport of the mobile work machine 31 be carried out with extremely high efficiency.

It should be noted that, in the foregoing embodiment, information required for transportation on the operator side terminal 12 of the transport vehicle 35 be displayed by entering a request using the terminal 11 on the part of the administrator. However, information required for services such as maintenance and inspection can also be found on the terminal 12 a service person are displayed, which the service vehicle 34 moves by entering a request using the terminal 11 on the part of the administrator.

In this case, similarly, an electronic mail including mobile body information, which is data about the present position, service data and irregularity data for the mobile work machine 31 contained by the administrator-side terminal 11 via the mobile work machine 31 to the terminal 12 transferred to the service person.

When the electronic mail to the terminal 12 the service person is received, request receiver identification data D2 (mobile work machine 31 ) and mobile body information data D3 '(vehicle position data and abnormality data (error code)) are read from the electronic mail data. The content of the electronic mail, that is the current position and a currently occurring irregularity element (error code) of the mobile work machine 31 , will then appear on a screen of the terminal 12 displayed.

In this way, the service person who is the service vehicle 34 drives, capable of specific mobile work machine 31 Furthermore, it is able to identify, on the screen of the terminal, the service provided by the administrator 12 determine the current vehicle position and the currently occurring fault element (fault code), which for the service on the mobile work machine 31 required are. Furthermore, the service person is on the side of the terminal 12 able to see from the screen of the terminal 12 to receive only the information required for the process without performing an information request entry. In other words, even if the service person wishing to receive information is in a situation where an input is at the terminal 12 can not be performed, the information required for the operation can be obtained. As a result, a maintenance, inspection and the like operation on the mobile work machine 31 be carried out with extremely high efficiency.

The following describes a case where the server terminal 21 the administrator side terminal is.

In this case, information required to consolidate the management of multiple mobile bodies may be available at the server terminal 21 on the admin page by entering a request using the terminal 12 on the part of the service person driving the service vehicle. For example, if a service person uses the oil in the mobile work machine 31 refills, the service person himself determines on the spot whether sufficient oil has been refilled, so there is no need, this on a screen of the terminal 12 to confirm. However, there is a need to provide information to the administrator indicating that the oil refilling process is complete, so that the time of the next oil replenishment can be scheduled.

Again, in a similar way an electronic mail, which as mobile body information data on the current amount of oil of the mobile machine 31 contains, from the terminal 12 on the part of the service person via the mobile work machine 31 to the server terminal 21 transfer.

When the electronic mail from the server terminal 21 is received, the request receiver identification data D2 (mobile work machine 31 ) and the mobile body information data D1 '(oil amount data) are read from the data in the electronic mail. The content of the electronic mail, that is, the current amount of oil of the mobile machine 31 , then appears on a display screen of the server terminal 21 displayed.

In this way, the administrator is capable of the particular mobile work machine 31 It will also be able to identify from the screen of the server terminal 21 to operate the current amount of oil required for the management of this mobile work machine 31 is required. Furthermore, the administrator is on the side of the server terminal 21 able to get out of the screen of the server terminal 21 only gain the information required for management without making an information request entry. In other words, even if the administrator who wishes to obtain information is in a situation in which an input to the server terminal 21 can not be performed, the information required for the management of the mobile body can be obtained. As a result, consolidated administrative operations for the mobile body 31 to 35 be carried out with extremely high efficiency.

at the embodiment described above however, the request originating terminal and the display receiving terminal are different can the request originating terminal and the display receiving terminal be the same.

For example, by request input using the terminal 11 on the part of the operator of the mobile working machine 31 Information required for an initial inspection on the same terminal 11 are displayed. The operator of the mobile work machine 31 performs this request entry using the terminal 11 in an office before he gets in the vehicle.

Also in this case, an electronic mail, which is data on the current amount of fuel and oil amount data for the mobile machine in a similar manner 31 as mobile body information from the terminal 11 via the mobile work machine 31 to the terminal 11 transfer.

When the electronic mail from the terminal 11 is received, request receiver identification data D2 (mobile work machine 31 ) and mobile body information data D3 '(fuel quantity data and oil amount data) are read from the data in the electronic mail. The content of the electronic mail, that is the current amount of fuel and the amount of oil of the mobile machine 31 will be on a screen of the terminal 11 displayed.

In this way, the operator of the mobile work machine is able, based on the screen of the terminal 11 to determine the actual amount of fuel and the amount of oil required for an initial inspection of the specific mobile work machine 31 are required, in which he should get into. In this case, the operator on the side of the terminal 11 from the screen of the terminal 11 just pre-obtained the information needed for an initial inspection, without actually using the mobile work machine 31 to approach. As a result, an actual inspection of the mobile work machine 31 easily and efficiently, and defects discovered during the initial inspection can be remedied in advance.

Similarly, by request input using the terminal 11 on the part of the operator of the transporter 35 for the mobile work machine, information required for a transport operation, at the same terminal 11 are displayed. As a result, the van is 35 for the mobile work machine able to leave the screen of the terminal 11 to acquire the mobile body information (current position, present fuel amount, etc.) necessary for the transportation of the particular mobile work machine to be transported 31 required are. In this case, the operator on the side of the terminal 11 on the screen of the terminal 11 advance only retrieve the information that is required for the transport process, without actually the mobile machine 31 to approach. As a result, the transport of a mobile work machine 31 be carried out easily and efficiently, and errors can be corrected in advance.

Similarly, by request input using the terminal 11 on the part of the service person, which the service vehicle 34 drives information required for services such as maintenance and inspections to the same terminal 11 are displayed. As a result, the service person carrying the Ser vice vehicle 34 leaves, from the screen of the terminal 11 read the mobile body information (current position, occurrence of irregularities, number of operating hours) required to perform services on the particular mobile work machine 31 to be performed at the service work are required. In this case, the service person on the part of the terminal 11 from the screen of the terminal 11 in advance, retrieve only the information necessary to perform service without actually using the mobile work machine 31 to approach. As a result, the mobile work machine can 31 be easily and efficiently maintained, and bugs can be fixed in advance. In other words, irregularities can be detected before looking at the mobile work machine 31 actually approaching, and in this way, parts can be ordered efficiently, assistance can be requested and repair procedures can be checked.

Further, according to this embodiment, the effect is achieved that the last information MD concerning all the mobile bodies which the plurality of mobile bodies 31 to 35 and according to request inputs from the multiple terminals 11 . 12 ... have been updated at any terminal (for example Terminal 11 ) can be displayed. This will be described below with further reference to 33 described.

As previously described, when an electronic reply mail to the server terminal 21 from the mobile work machine 31 is transmitted out, the mobile body information extraction program becomes in the server terminal 21 whereupon the mobile body information data D3 '("vehicle position data", "fuel amount data") and the request receiver identification data D2 ("mobile work machine 31 ") are extracted from the content of the electronic mail sent in the mailbox of the display recipient terminal 12 is stored, and the latest vehicle position data and fuel quantity data become according to the address of the mobile work machine 31 saved. As a result, the content of the information MD concerning all mobile bodies is updated. Then, the Web site update processing program will be in the server terminal 21 whereupon the mobile body information is updated on the appropriate screen of the web site corresponding to the last all mobile body related information MD stored in the server terminal 21 are stored. As with time series data (like the in 29 shown fuel quantity time series data). The oldest data is deleted when the most recent data is added.

When the WWW browser through the terminal 11 will then be the updated website data from the server terminal 21 read via the WWW browser. In this way, the information concerning the last mobile body information concerning all mobile bodies MD is updated on a screen of the terminal 11 displayed. In other words, if the terminal 11 from the server terminal 21 receives an input for requesting the latest information concerning all mobile bodies MD, the last information concerning all mobile bodies MD is displayed on the screen of the terminal 11 displayed.

It is assumed herein that the in 27 displayed on the terminal 11 is shown.

Subsequently, the icon of the mobile work machine 31 on the in 27 shown map and this displayed at a position on the map according to the latest (current) vehicle position data.

If to the in 28 is changed, the display of the numerical values of the "position data" and the "fuel quantity" on the screen are respectively changed to the latest (current) numerical values of the vehicle position data and the last numerical value of the fuel amount. If a change to the in 29 or 30 screen is displayed, the display of the fuel quantity time series curve or the operating map is switched to the last version.

Thus, in the above-described embodiment, the last information MD relating to all the mobile bodies, which relates to the plurality of mobile bodies 31 to 35 and according to a request input from the plurality of terminals 11 . 12 were updated on a screen of the desired terminal 11 are displayed. As a result, the last mobile body information representing the multiple mobile bodies 31 to 35 can be obtained at a desired terminal, with the effect that all mobile bodies can be managed and monitored. In other words, the last mobile body information representing the multiple mobile bodies 31 to 35 and requested by several requesting parties can be managed together at a desired terminal.

In this embodiment, a database is for each of the server terminals 21 . 22 are provided, and the mobile body relevant information MD are stored individually. By transferring the data (all mobile Body information MD) stored in the database of one of the server terminals in the database of the other server terminal, the information concerning all mobile bodies can also be used in the database of the other server terminal, and the memory contents (the information concerning all mobile bodies MD) of the database in each of the server terminals can be unified. In particular, this is achieved by a method in which an electronic mail received in response from one of the server terminals (in which mobile body information is written) is automatically transmitted to the other server terminal.

As previously mentioned, in the service vehicle 34 a terminal 13 installed with the terminal 11 and the terminal 12 is identical, and the function of the car navigation device 55 is in the terminal 13 included and functional.

The following describes an embodiment in which work instruction data is attached to that in the service vehicle 34 existing terminal 13 from the administrator-side terminal 11 be transmitted from such that work instructions are transmitted to a service person. A service person often performs work such as repairs, parts replacement, inspections, etc., and therefore has little opportunity for direct contact with the administrator. By the system of this embodiment, there are no restrictions on the reception of the instructions in terms of time and work so that the work instructions can be received efficiently.

As in 33 displayed by the administrator-side terminal 11 sent an electronic mail to which data is attached, that in the service vehicle 34 installed terminals 13 as the display receiver terminal (display receiver identification data D4), data indicating the mobile work machine 31 as the request-receiver mobile body (request-receiver identification data D2) and data containing a message "failure E has occurred, promptly go on-site". Here, the message data "fault E has occurred, promptly go on site" to the electronic mail through an input to the input device of the terminal 11 attached.

As in 3 shown, become an icon of the mobile work machine 31 , which is the subject of the service work, and an icon of the service vehicle 34 even on a map on a screen 13a of the terminal 13 of the service vehicle 34 , which is the display receiver terminal, is displayed in its last (current) position. It should be noted that the position of the vehicle 34 even from the GPS sensor 57 who is in the vehicle 34 even installed, detected and on the screen 13a is pictured. The message transported in the electronic mail message "instruction message: fault E has occurred, promptly go on site") is in a message area 103 the screen display of the terminal 13 displayed.

As a result, this is the service vehicle 34 moving service person able to look at the screen 13a to recognize that the next service item (receiver) is the mobile work machine 31 is to recognize their current position and to read a message regarding the work content. An automatic route builder is in the terminal 13 saved. If this automatic route creation program with the current position and the receiver (the current position of the mobile machine 31 ) of the vehicle 34 is provided processing is performed to automatically create the shortest route on the map. When the automatic route creation program has been executed, the shortest route becomes 102 from the current position of the vehicle 34 even to the current position of the mobile work machine 31 , which is the receiver, on the screen 13a of the terminal 13 displayed.

As a result, the service person can service vehicle 34 according to the screen 13a of the terminal 13 drive and work at the receiver.

If the work is possible according to the content of the work order, an "OK-Button" 110 on the display screen 13a angeclickt. If the service vehicle 34 at the receiver 34 arrives and the work begins, a button "Arrived" 113 on the screen 13a angeclickt. If the service work on the mobile machine 31 is completed, the button becomes 112 "Completed" 112 on the screen 13a angeclickt. If, for certain reasons, the work can not be accepted according to the content of the work instruction, a button "Stop" will also be displayed. 111 on the screen 13a angeclickt. The input content of these clicks to the terminal 13 is from the terminal 13 to the administrator-side terminal 11 transmitted as electronic mail. If this electronic mail from the terminal 11 is received, the work progress of the service vehicle 34 be learned. It should be noted that a voice input instead of a touch input, such as a click, a key press or a Paneltouch input, can be done.

Thus, service operations such as maintenance and inspection are performed with extremely high efficiency. In particular, in this embodiment, the last position of the mobile work machine 31 on the screen 13a displayed so that the vehicle 34 Can be reliably controlled without getting lost, even if the service item 31 moved on the job.

• 1] Nachrichtendaten "Störung E ist aufgetreten, umgehend vor Ort begeben" werden von dem Terminal 11 an das Terminal 13 als elektronische Mail übertragen.
• 2) der WWW-Browser in dem Terminal 13 wird aktiviert und die aktualisierten Websitedaten werden von dem Serverterminal 21 über den WWW-Browser gelesen. Hierbei wird die letzte Position der mobilen Arbeitsmaschine 31 auf einem Bildschirm des Terminals 13 als die letzten sämtliche mobilen Körper betreffenden Informationen MD angezeigt.

The content of 3 can also be in the following sequence at the terminal 13 are displayed:

• 1] Message data "Fault E has occurred, to be dispatched immediately on-site" are sent from the terminal 11 to the terminal 13 transmitted as electronic mail.
• 2) the WWW browser in the terminal 13 will be activated and the updated website data will be from the server terminal 21 read via the WWW browser. This will be the last position of the mobile work machine 31 on a screen of the terminal 13 as the last information concerning all mobile body MD is displayed.

The content of the from the administrator side terminal 11 transmitted work instruction data indicating the mobile body position and the work content is arbitrary. For example, the work content may one day be instructed as work content. In this case, the work efficiency of the service vehicle 34 be learned for a day when the work card ( 30 ) of the service vehicle 34 from the server terminal 21 through the administrator-side terminal 11 is requested. By comparing the work efficiency for a day with that of the administrator to the service vehicle 34 output work content for one day, a daily work report can be automatically and accurately created.

Furthermore, the position of another service vehicle 34 ' from the administrator-side terminal 11 and the location of the service item (the position of the mobile work machine 31 ) to the terminal 13 of the service vehicle 34 be transmitted. This will change the position of another service vehicle 34 ' on the screen 13a of the terminal 13 of the service vehicle 34 displayed, and as a result, the movement is in the direction of this service vehicle 34 ' as well as the contact with this easier and the service work can be carried out even more efficiently. In other words, tools, replacement parts, and the like may be borrowed from the other service person and support requests may be made. Further, when the other service person is well trained, counseling and the like can be performed.

In the above-described embodiment, further, data regarding the position of the mobile work machine is obtained 31 from the administrator side terminal 11 to the terminal 13 of the service vehicle 34 However, the positions of several mobile work machines can be transferred 31A . 31B . 31C . 31D be transferred, so that a service tour of the several mobile work machines 31A to 31D can be carried out efficiently.

In this case, work instruction data representing the current positions of the plurality of mobile work machines 31A to 31D and operating hours counter increments ("3H", "678H", "10H", "500H") for each of the mobile work machines 31A to 31D from the previous tour to the present time, to the terminal 13 of the service vehicle 34 transfer.

As in 5 4, icons representing the current positions of each of the mobile work machines are shown 31A to 31D and the operating hours counter rise value for each of the mobile work machines 31A to 31D on a map on the screen 13a of the terminal 13 in the service vehicle 34 displayed. If, for example, the mobile work machine 31D from its previous position (shown in dashed lines), its current position (shown in solid lines) on the map is displayed on the screen 13a displayed.

A program for automatically creating a tour route is also in the terminal 13 saved. If this program to automatically create a tour route with the current position of the vehicle 34 itself and several tour venues (the mo bile machines 31A to 31D ), only the tour item locations having hour count increase values higher than a predetermined value are selected, and then processing is performed to automatically create the most efficient tour route through those selected tour item locations. When the automatic tour route creation program is executed, a round trip route is shown in solid lines 108 from the current position of the vehicle 34 over the mobile machines 31B . 31D having high operating hour count increase values ("678H", "500H") and back to the home position of the vehicle 34 on the screen 13a of the terminal 13 displayed.

When a service person performs work on each of the tour venues by connecting with the service vehicle 34 the circular route shown in solid lines 108 according to the screen 13a of the terminal 13 a service tour can be carried out with an extremely high efficiency. Conventionally, as indicated by the dashed line in FIG 5 shown, one through all of the mobile work machines 31A to 31D running tour route 109 uniformly given after a predetermined period of time after the previous service tour, so that the work is performed on all vehicles. However, according to the present embodiment, the works will be along the tour route 108 carried out the mobile work machines 31A . 31C does not take into account the operating time since the previous service tour has not increased (operating hours counter rise value "3H", "10H"), so that unnecessary work can be avoided.

It should be noted that the solid line in 5 illustrated tour route 108 according to an assessment by the service person instead of being planned by an automatic creation.

In the aforementioned embodiment, work order data is acquired from the administrator side terminal 11 to the terminal 13 transferred in the service vehicle 34 is installed. However, the work order data may be from the administrator-side terminal 11 to that in the van 35 Terminal installed for the mobile work machine 14 be transferred so that the transport and loading operations can be carried out efficiently.

In this case, an electronic mail with data for the current position of the mobile work machine 31 , which is the point of loading, the position of an unloading point 106 at which the loaded vehicle is to be unloaded and a message "Back to completion" to the terminal 14 of the transporter 35 transferred for the mobile work machine.

Subsequently, the current position of the mobile work machine 31 and the position of the unloading point 106 as icons on a map of a screen 14a of the terminal 14 of the transporter 35 displayed as in 4 shown. It should be noted that the current position of the vehicle 35 from the GPS sensor 57 in the vehicle 35 captured and on the screen 14a is shown. In addition, the message transmitted in the electronic mail ("order message: back to completion") also becomes a message area 107 the screen of the terminal 14 displayed. In this way, the operator of the transporter 35 on the screen 14a determine that the next transport item is the mobile work machine 31 and their current position, the location where the vehicle is to be unloaded and the specific work contents.

An automatic transport route creation program is also in the terminal 14 saved. This automatic transport route creation program processes to automatically create the shortest transportation route from the current position of the vehicle 35 to the loading point 31 and on to the unloading point 106 , where only Straßenge be selected, which is for a passage of the vehicle 35 are wide enough. Running the automatic transport route creation program becomes the shortest transport route 104 from the vehicle 35 via the mobile work machine 31 to the unloading point 106 created, being a road 105 is avoided, which for the passage of the vehicle 35 too narrow, and on the screen 14a of the terminal 14 displayed.

If the work is possible according to the content of the work order, an "OK-Button" 110 on the display screen 14a angeclickt. If the van 35 at the loading point 31 arrives and the loading work begins, a button "Loading" 114 on the screen 14a angeclickt. If the van 35 at the unloading point 106 arrives and unloading begins, a butt will "dump" 114 on the screen 14a angeclickt. If the van 35 the loading and transport work (unloading work) has finished, the button becomes 112 "Completed" on the screen 14a angeclickt. If the work can not be accepted for certain reasons according to the content of the work instruction, a button "Halt" 111 on the screen 14a angeclickt. The input content of these clicks to the terminal 14 is from the terminal 14 to the administrator-side terminal 11 transmitted as electronic mail. If this electronic mail from the terminal 11 can receive the work progress of the transporter 35 be learned. It should be noted that a voice input instead of a touch input, such as a click, a key press or a Paneltouch input, can be done.

When the operator does the work by stopping the transport route 104 with the transporter 35 according to the screen 14a of the terminal 14 carrying out a loading and transport work (unloading work) can be carried out with extremely high efficiency. Another degree of efficiency can be achieved when the transporter 35 another mobile work machine 31 to 33 transported on the return journey after unloading (when the vehicle is empty).

Work order data can also be obtained from the administrator-side terminal 11 be transmitted to a terminal in a mobile work machine 31 For example, a hydraulic excavator is installed, so that excavation work or the like can be performed efficiently.

By transmitting data indicating target picking amount for the day, the working end time, and the present position of the charge receiver dump truck to the terminal in the mobile work machine 31 , these items are displayed on a screen of the terminal and the operator operates the work machine according to the display screen so that a series of excavation and dump truck loading operations can be performed efficiently.

In this embodiment, data is using an electronic mail server on the Internet 2 transmit and receive. In such a case, the server terminal checks 21 , which serves as a mail server, the presence of electronic mail in a mailbox at fixed intervals. As a result, a fixed delay between the transmissions of an electronic mail from a terminal (for example, the terminal 11 ) and the actual reception thereof by a mail recipient mobile body (for example, the mobile work machine 31 ) on.

In this embodiment, data is transmitted by wireless satellite communication using the communication satellite 9 transmit and receive. In wireless satellite communication, the communication line 5 are not considered assured when the communication environment between the transmitter and the receiver is unfavorable, as in cases where the maximum elevation angle of the satellite is small and the line of sight to the mobile body can not be realized, therefore, processing is performed to repeatedly enable communication to attempt. As a result, a delay caused by the communication environment arises between the data transmission from the communication satellite 9 and the actual reception in a mobile body (the mobile work machine 31 ).

at the communication system according to this embodiment is interposed the transmission an electronic mail from the request originating terminal and receiving them in the request receiver mobile body a time difference generated by, for example, several minutes. In such a Communication system with a low real-time quality arises at the operator of the request originating terminal a sense of insecurity due to the unknown communication status that affects can have the work efficiency. There may also be communication costs arise when a duplicate electronic mail re-blanks because the status of the communication is unknown.

It is therefore desirable a reduction in work efficiency and an increase in communication costs, which causes an unknown status of the communication are, by avoiding the communication status with each mobile body a screen of a terminal.

Further be in this embodiment Requirements of mobile body information of several terminals regarding a mobile body output. It is therefore impossible using only one terminal, the novelty of the currently obtained Mobile body information to judge (when the mobile body information request took place).

It is therefore desirable that an operator over Mobile body management information in terms of the novelty of present obtained mobile body information gets by the last since a mobile body elapsed time is displayed on a screen.

One in the following described embodiment is to these needs aligned.

As in 31 are shown, icons serving as mobile body identifiers (an image of a Hydraulic excavator, an image of a service vehicle, a picture of a semi-trailer, and the like) on the terminal 11 each corresponding to the plurality of mobile bodies 31 to 35 displayed. When an electronic mail requesting mobile body information from the request originating terminal 11 to the mobile work machine 31 , which is the recipient of the request, is transmitted, the display content of the icon of the mobile work machine changes 31 as in 16 (a) displayed according to the communication status.

In particular, as in 16 (a) shown, the color of the icon of the mobile machine 31 from "blue" to "yellow" to "green" to "red" according to changes in communication status between the terminal 11 and the mobile work machine 31 or, in other words, the communication sequence, from "no request" to "request in progress" to "receive response" to "no answer".

This will be with reference to the flow chart of 15 described.

15 Fig. 15 shows a processing sequence for changing the display according to the communication sequence. This processing is done by the server terminal 21 performed and the results of this processing are displayed on a screen of the terminal 11 displayed.

In an initial state, the icon of the mobile work machine 31 "blue" is displayed, which corresponds to "no request" (step 201 ).

When an electronic mail requesting mobile body information from the request originating terminal 11 to the mobile work machine 31 , which is the recipient of the request, is transmitted, and the electronic mail in the mailbox of the mobile work machine 31 is stored (YES in step 202 ), the display color of the icon of the mobile work machine changes 31 to "yellow", which corresponds to "work in progress" (step 203 ).

If the electronic mail coming from the mobile machine 31 which is the recipient of the request, is transmitted in response, is stored in the mailbox (YES in step 204 ) changes the display color of the icon of the mobile machine 31 to "green", which corresponds to "answered" (step 207 ). After a day has elapsed from the change of the communication status to "answered" (YES in step 208 ), the display color of the mobile machine icon changes 31 back to "blue", which corresponds to the state "no request" (step 201 ). In this case, the step 207 to the step 201 and the display color may return to "blue," which corresponds to the "no request" state as soon as the mobile body information in response to the display receiver terminal (e.g., terminal 12 ) and displayed.

If, on the other hand, that in response from the mobile work machine 31 that is the recipient of the request to be transmitted is not stored in the mailbox (NO in step 204 and YES in the step 205 ), it is found that the reason for this in difficulty in ensuring the wireless communication line 5 is, and the display color of the icon of the mobile machine 31 changes to "red", which corresponds to the state "no answer" (step 206 ).

In the foregoing description, a case has been assumed where a request for mobile body information from the terminal 11 off to the mobile work machine 31 was directed. However, if mobile body information from each of the terminals 11 . 12 , ... of each of the mobile bodies 31 . 32 . 33 . 34 . 35 be requested, the display color of the icon for the request receiver mobile body similarly changes in accordance with the communication state in the request output terminal.

According to the above-described embodiment, when communication devices of low real-time quality are used, the "degree of communication delay" can be determined from a screen of the terminal 11 from the changes of the display colors according to the communication status. Furthermore, duplicate requests to other terminals are eliminated. As a result, deterioration of work efficiency and increases in communication costs due to an unknown communication status can be avoided.

Next, an embodiment will be described in which the operator has mobile body management information regarding the novelty of the currently obtained mobile body information by displaying the time passed since the last mobile body request on a screen of a terminal 11 can be informed.

As in 18 As shown, the color of the icon of the mobile work machine changes 31 from "blue"("no requests # 0") to "yellow"("no requests # 1") to "pink"("no requests # 2") to "red"("no requests # 3") according to the Communication status between the terminals 11 . 12 ... and the mobile work machine 31 , or in other words: according to the changes in the time since the last request from the terminals 11 . 12 ... to the M ' mobile work machine 31 has elapsed from "no requirements for a day or less" to "no requirements for one to three days" to "no requirements for three days to a week" to "no requirements for a week or more".

As in 18 an electronic mail requesting mobile body information is presented from the terminals 11 . 12 ... to the mobile work machine 31 which is the recipient of the request, and if this electronic mail in the mailbox of the mobile work machine 31 is stored (YES in step 301 ), a timer is reset (step 305 ) and the display color of the mobile work machine icon 31 changes to "blue", which corresponds to the state "no requirements # 0" (step 306 ).

If the time elapsed since the timer reset is one day or less (NO in step 302 ), the display color "blue" corresponding to the condition "no requests # 0" becomes the icon of the mobile work machine 31 maintain (step 306 ).

If the time elapsed since timer reset exceeds one day but is within or within three days (YES in step 302 and NO in the step 303 ), the display color of the icon of the mobile work machine changes 31 to "yellow", which corresponds to the state "no requirements # 1" (step 307 ).

If the time elapsed since the timer reset exceeds three days but is within or within one week (YES in step 303 and NO in step 304 ), the display color of the icon for the mobile work machine changes 31 to "pink", which corresponds to the condition "no requirements # 2" (step 308 ).

If the time elapsed since timer reset exceeds one week (YES in step 304 ), the display color of the icon of the mobile work machine changes 31 to "red", which corresponds to the condition "no requirements # 3" (step 309 ).

When an electronic mail requesting mobile body information from the terminals 11 . 12 ... to the mobile work machine 31 which is the recipient of the request, during the time recording is transmitted by the timer, and if this electronic mail in the mailbox of the mobile work machine 31 is saved (YES in step 301 ), the timer is reset (step 305 ) and the display color of the mobile work machine icon 31 changes to "blue", which corresponds to the state "no requirements # 0" (step 306 ).

In the above description, a case was assumed in which the since the last request by the terminal 11 to the mobile work machine 31 elapsed time is displayed. However, the display is similarly made for the other mobile bodies as well 32 to 35 , The since the last request to each of the mobile body 31 . 32 . 33 . 34 . 35 from another terminal 12 ... elapsed time is also displayed.

According to the embodiment described above, since the last request to the mobile body 31 to 35 elapsed time are recognized on a screen of a terminal, so that management information regarding the novelty of the currently obtained mobile body information for the mobile body 31 to 35 can be learned.

Various changes can be made to the aforementioned embodiment. These are described below with reference to the 16 (b) to 16 (d) . 17 . 19 and 20 described.

The following will describe an embodiment in which an operator is informed of mobile body management information regarding the novelty of the currently obtained mobile body information by displaying on a screen of the terminal 11 the time that has elapsed since the last receipt of electronic mail from a mobile body containing mobile body information is displayed. Here, "receive" includes both the case that electronic mail containing mobile body information is transmitted in response from a mobile body, and a case to be described below, in which electronic mail containing mobile body information is automatically transmitted from a mobile body itself without request from the mobile body of the terminal.

As in 19 As shown, the color of the icon of the mobile work machine changes 31 from "blue"("no reception # 0") to "yellow"("no reception # 1") to "pink"("no reception # 2") to "red"("no reception # 3") according to the Changes in communication status with the mobile work machine 31 , or in other words: according to the changes in the time span since the last reception (answer, automatic transmission) from the mobile machine 31 to the server terminal 21 from "no reception for one day or less" to "no reception for one to three days" to "no reception for three days to one week" to "no reception for a week or more".

As in 19 is shown, if a Answer from the mobile work machine 31 or an electronic mail coming from the mobile work machine 31 is automatically transmitted in the mailbox of the server terminal 21 is stored (YES in step 401 ), the timer is reset (step 405 ) and the display color of the mobile work machine icon 31 changes to "blue", which corresponds to the state "no reception # 0" (step 406 ).

When the elapsed time since timer reset is one day or less (NO in step 402 ), the display color of the icon of the mobile work machine becomes 31 kept on "blue", which is the state "no reception # 0" (step 406 ) corresponds.

If the time elapsed since timer reset exceeds one day but is within or within three days (YES in step 402 and NO in the step 403 ), the display color of the icon of the mobile work machine changes 31 to "yellow", which corresponds to the condition "no reception # 1" (step 407 ).

If the time elapsed since the timer reset exceeds three days but is within or within one week (YES in step 403 and NO in step 404 ), the display color of the icon for the mobile work machine changes 31 to "pink", which corresponds to the condition "no reception # 2" (step 408 ).

If the time elapsed since timer reset exceeds one week (YES in step 404 ), the display color of the icon of the mobile work machine changes 31 to "red", which corresponds to the condition "no reception # 3" (step 409 ).

If an answer from the mobile work machine 31 or an electronic mail coming from the mobile work machine 31 is automatically transmitted in the mailbox of the server terminal 21 is stored during the time acquisition by the timer (Yes in step 401 ), the timer is reset (step 405 ) and the display color of the mobile work machine icon 31 changes to "blue", which corresponds to the state "no reception # 0" (step 406 ).

It should be noted that in the foregoing description, there is provided a case where the since the last reception from the mobile work machine 31 is displayed from elapsed time, but a display is similarly made for the other mobile bodies 32 to 35 , The since the last reception by the mobile body 31 . 32 . 33 . 34 . 35 elapsed time, will also be at the other terminals 12 ... displayed.

According to the embodiment described above, since the last reception of the mobile bodies 31 to 35 the elapsed time can be displayed on a screen of a terminal, and thus, management information regarding the novelty of the currently obtained mobile body information regarding the mobile body can be displayed 31 to 35 be learned. If a mobile body (for example, the mobile work machine 31 ) performs automatic transmission at fixed intervals, may further at the terminal based on the display content since the last reception of the mobile body 31 be determined whether a type of communication interruption in the automatic transmission by the mobile body 31 took place.

In the following, an embodiment with respect to 20 described in which the since the issue of a request to a mobile body until the output of a response to this elapsed time period is displayed, so that on the basis of the screen of the terminal 11 It can be determined whether the communication is carried out normally.

As in 20 As shown, the color of the mobile machine icon changes from "blue"("no answer # 0") to "yellow"("no answer # 1") to "pink"("no answer # 2") to "red""(" no answer # 3 ") corresponding to the change in the period of a persistent state in which no response to the last request from the terminal 11 to the mobile work machine 31 is output, or in other words: according to the changes from "no answer for a minute or less" to "no answer for a minute to three minute" to "no answer for three minutes to ten minutes" to "no answer for ten minutes or more". If the terminals 11 . 12 ... no requirements for the mobile work machine 31 has been directed (if an answer has been given), "blue"("norequest") is displayed.

As in 20 As shown, the color of the icon for the mobile work machine changes 31 to "blue", which corresponds to the state "no request" (step 506 ) when an electronic mail requesting mobile body information comes from the request originating terminal 11 to the mobile work machine 31 is transmitted and one from the receiving mobile work machine 31 In response, electronic mail is stored in a mailbox (YES in step 501 ).

If no electronic mail response from the requesting mobile work machine 31 stored in the mailbox (NO in step 501 ), the processing proceeds to the subsequent step 502 above.

In step 502 It is determined whether an electronic mail requesting mobile body information from the request originating terminal 11 to the mobile work machine 31 which is the recipient of the request, transmitted and in the mailbox of the mobile work machine 31 or, in other words, whether a request has been made (step 502 ).

If a request has been made (YES in step 502 ), the timer is reset, and when the time elapsed since the resetting of the timer is one minute or less (NO in step 503 ), the display color of the icon of the mobile work machine changes 31 to "green", which corresponds to the state "no answer # 0" (step 507 ).

If the time elapsed since timer reset exceeds one minute, but is within or within three minutes (YES in step 503 and NO in the step 504 ), the display color of the icon of the mobile work machine changes 31 to "yellow", which corresponds to the state "no answer # 1" (step 508 ).

If the time elapsed since timer reset exceeds three minutes, but is within or within ten minutes (YES in step 504 and NO in step 505 ), the display color of the icon for the mobile work machine changes 31 to "pink", which corresponds to the state "no answer # 2" (step 509 ).

If the time elapsed since the timer reset exceeds ten minutes (YES in step 505 ), the display color of the icon of the mobile work machine changes 31 to "red", which corresponds to the state "no answer # 3" (step 510 ).

If one from the requesting mobile work machine 31 e-mail transmitted in response is stored by the timer in the mailbox during the timekeeping (YES in step 501 ), the color of the icon for the mobile work machine changes to "blue", which corresponds to the condition "no request" (step 506 ).

It should be noted that the previous description was based on a case where the output of a request by the terminal 11 to the mobile work machine 31 is displayed until the issuing of a response thereto, but the display is made for the other mobile bodies 32 to 35 similar. The since the issue of a request to the mobile body 31 . 32 . 33 . 34 . 35 will also be at the other terminals 12 , ... displayed.

at the embodiment described above the time that elapses between issuing a request is displayed to a mobile body until the output of an answer has elapsed, and so on can be easily determined from a screen of a terminal whether the communication is normal.

It should be noted that in the foregoing description, as in 16 (a) shown, the display color of the entire icon of the mobile machine 31 according to the communication status between the terminal 11 and the mobile work machine 31 changed. However, the color combination, color scheme, pattern and the like of the icon may also be changed. Further, another characterizing element other than the color may be changed.

For example, as in 16 (b) represented, the shape of the icon for the mobile work machine 31 according to the communication state between the terminal 11 and the mobile work machine 31 changed who the. For example, in the case of an icon for a hydraulic excavator, the position, radius and the like of the attachment may be changed.

Furthermore, as in 16 (c) represented, the size of the icon of the mobile work machine 31 according to the communication status between the terminal 11 and the mobile work machine are changed. In the case of the section "requirement in work" in 16 (c) For example, the size of the icon of the hydraulic excavator changes periodically from large to medium and from medium to large.

In addition, as in the 16 (d) illustrated, the movement of the icon of the mobile work machine 31 according to the communication status between the terminal 11 and the mobile work machine 31 to be changed. In the case of the section "no requirement" in 16 (c) For example, holding the icon of the hydraulic excavator while the icon of the hydraulic shovel is rotating in the "work in progress" section, the icon of the hydraulic shovel moves in a straight line in the case of the "answer" section, and the icon of the hydraulic shovel in the case of the shovel Section "no answer" jumps.

The flashing pattern of the mobile working machine icon 31 can also be according to the communication state between the terminal 11 and the mobile work machine 31 to be changed. For example, the blinking period can be changed.

Instead of changing the image of the mobile work machine 31 can identify codes such as signs for identifying the mobile work machine 31 to be changed. For example, the license plate of the mobile work machine 31 or the color of the letters of a call name or the like are changed or blinking.

As a result of the processing of 15 For example, icons become for several mobile machines 31 . 32 . 33 . 36 . 37 . 38 on a screen of the terminal 11 according to the mobile body information ("vehicle number", "position", "hour meter") as shown in FIG 17 (a) shown. As in 17 (a) In this case, the icons of each of the mobile work machines can be shown 31 . 32 . 33 . 36 . 37 . 38 be displayed on the screen in a preset sequence.

Like in the 17 (b) shown, the icons of mobile machines 31 . 32 . 33 . 36 . 37 . 38 be arranged according to the communication state, the icons of the mobile machines 31 . 32 that correspond to the "work in progress" state, shown above, while the icons of the mobile work machines 33 . 36 . 37 , which correspond to the state "no request", are displayed below.

As in 17 (c) Furthermore, only the icons of the mobile machines can be shown 31 . 32 which correspond to the "work in progress" state from the icons for each of the mobile work machines 31 . 32 . 33 . 36 . 37 . 38 extracted and displayed.

To this embodiment described above the display content of a terminal changes accordingly changed the communication status, and thus a reduction in work efficiency due to a unknown communication status as well as an increase in communication costs be prevented. Furthermore, can Administrative information regarding the novelty of the mobile body information for each mobile body (Time of last maintenance or inspection and the like) be read from a screen.

This embodiment, in which the display content of a terminal is changed in accordance with changes in the communication status, is not limited to that in FIG 1 limited communication system, but can be applied to any communication system. This embodiment is applicable to a communication system having at least two communication stations, so that communication between the two communication stations can be performed.

In the following an embodiment will be described in which the mobile body 31 to 35 switch off their power supply intermittently to avoid unnecessary energy consumption during communication.

Time window, while which is the engine of a mobile work machine, such as a construction machine, not working (or in other words: the Period in which the power supply is switched off) are long.

If, as in 21 shown, the battery 63 , which works as a power supply (rated voltage 24V), always electrically connected to the communication terminal 56 remains connected, even when the engine is switched off, the battery 63 not charged by a generator (alternator) because the engine is not in operation. As a result, the electric discharge of the battery proceeds 63 fast forward. On the other hand, if the electrical connection between the battery 63 and the communication terminal 56 is switched off, once the engine is off, communication with the multiple terminals 11 . 12 ... impossible. If on the part of the terminals 11 . 12 Consequently, when mobile engine information is requested when the engine is off, this request can not be answered.

Therefore, in the following embodiment, it is provided that the communication with the plurality of terminals 11 . 12 ... is possible with the engine off, even on mobile machines 31 to 35 For example, construction machinery whose engines are not operated for long periods, which is why requirements on the part of the terminals 11 . 12 .. can be answered and unnecessary energy consumption can be avoided.

21 shows the construction of this embodiment.

As in 2 is shown, the vehicle chassis interior of the mobile machine 31 with the communication terminal 56 Mistake. The energy terminal of this communication terminal 56 is electric with the battery 63 connected. A main power supply circuit is in the communication terminal 56 provided, and energy is provided by the supply of electrical energy from the battery 63 applied to the main power supply circuit. Either is an internal program (software timer) in the communication terminal 56 is stored, or an internal power supply circuit (hardware timer) is provided therein, by which means the drive of the main power supply circuit is intermittently off and on, so that the energy saving periodically over the Hauptener power supply circuit takes place.

The level of an engine ignition switch signal S1 entering a sleep control terminal of the communications terminal 56 is monitored by software, and when the level is an on signal and the main power supply circuit of the communication terminal 56 is turned off, there is a processing for forcibly driving the main power supply circuit. There may also be provided a structure in which the main power supply circuit is driven by hardware.

More specifically, if an off signal (a logic "0" signal) of the engine ignition switch signal S1 enters the sleep control terminal of the communication terminal 56 is entered, the electrical connection between the main power supply circuit in the communication terminal 56 and the battery 63 on and off in a predetermined power stroke, the main power supply circuit is controlled on and off, and the communication terminal 56 is activated and deactivated, whereby a communication processing is performed periodically (sleep function of the communication terminal 56 is a).

When an on signal (a logic "1" signal) of the engine ignition switch signal S1 enters the sleep control terminal of the communication terminal 56 is input, the main power supply circuit in the communication terminal 56 and the battery 63 electrically connected to each other such that the main power supply circuit is driven, the communication terminal 56 is activated, and a communication processing is performed (the sleep function of the communication terminal 56 is off (forcibly canceled)). The communication terminal 56 is in the activated state as soon as the motor is switched on.

The energy terminal of the communication controller 54 is electric with the battery 63 via a motor ignition switch 64 connected. If the engine ignition switch 64 is switched off, the electrical connection between the communication controller 54 and the battery 63 interrupted, and the engine of the mobile machine 31 stops the operation.

If the engine ignition switch 64 is turned on, an on-signal (a logical-level signal "1") of the engine ignition switch signal S1 from the communication controller 54 to the sleep control terminal of the communication terminal 56 output.

The following is based on the timing diagram of 7 that of the communication terminal 56 performed processing described.

7 (a) shows the operating signal S1 of the engine ignition switch 64 and 7 (b) shows the communication state between the communication terminal 15 and the communications satellite 9 , Communication is indicated by the logic level "1". 7 (c) shows a state of activation of the communication terminal 56 , The logic level "1" corresponds to the activated state (energy-saving mode off), and the logic level "0" corresponds to a state of the activation switched off (sleep state) (energy-saving mode on). The communication terminal 56 is intermittently activated and deactivated in accordance with the work clock D (= (τ / T) × 100%). At the time of activation of the communication terminal 56 When the power save mode is turned off, signals indicating mobile body information such as the current position, the running hour counter value, the remaining fuel amount, the battery voltage, and vehicle fault codes are output from the communication terminal as needed 56 on the communications satellites 9 transfer.

As in 7 shown, remains the communication terminal 56 always activated when the engine ignition switch signal S1 is kept in an on state.

When the engine ignition switch signal S1 is switched from on to off, the communication terminal becomes 56 corresponding to the power stroke D (= (τ / T) × 100%) is intermittently activated and deactivated, as shown by the arrow a (sleep function on).

8 (b) is a timing diagram that shuts off the on and off power saving modes 7 (c) represents, and 8 (c) shows the state in which a call signal from the communication satellite 9 to the communication terminal 56 is transmitted. The logic level "1" indicates the transmission.

As shown in these drawings, within a fixed period (activation period) T, there is always an activation period τ, or in other words a period, in the transmission and reception via the communication satellite 9 can be done (see shaded area in 8 (c) ). The expected communication response time is T / 2 (average T / 2). The energy consumption can be limited to τ / T. To transfer and receive between the communications satellites 9 and de, energy-saving mode communication terminal 56 during the activation period T, signals from the communi cation satellites) over a period of T or more (see 8 (b) , (c)) to the communication terminal 56 be transmitted. The activation period T becomes according to the degree of urgency of the communication and the safety factor regarding the continuous period of the signal transmission from the communication satellite 9 certainly.

It It must be ensured that the activated period τ at or above the Time is sufficient for a transmission and receiving process is required. However, the energy savings with decreasing activated period τ more effective.

By thus periodically activating the communication terminal 56 during a period T, the value of the expected communication reaction time can be ensured and the power consumption can be reduced.

As in 7 however, even if the engine ignition switch signal S1 is switched from on to off, in case of ongoing communication between the communication terminal 56 and the communications satellite 9 as shown by the arrow c, the sleep function is turned on when the communication ends, as indicated by the arrow d.

If the engine ignition switch signal S1 is switched from off to on, the sleep function is forcibly canceled, as shown by the arrow b.

According to the embodiment described above, the sleep function is forcibly canceled when the engine is running and the communication terminal 56 is always activated when the engine is operated, and thus mobile body information regarding sudden vehicle disturbances can be transmitted during operation of the engine, so that safety is ensured. Even if engine operation is stopped, the communication terminal remains 56 during communication until the communication is completed, and thus the communication can be reliably performed.

The aforementioned power stroke D can be according to the pole voltage of the battery 63 be changed.

The voltage of the battery 63 is input to a battery voltage input circuit, and the duty cycle D changes according to that in FIG 8 (a) represented characteristics.

That is, the duty cycle D decreases and the activation period T increases as the voltage of the battery increases 63 decreases, and thus further reductions in the voltage of the battery 63 avoided.

Further reducing the voltage of the battery 63 can also be prevented by a similar characteristic as in 8 (a) is used, so that with decreasing engine operating time of the duty cycle D is reduced and the activation period T is extended. The engine operating time is determined from the increase value of the operating hours counter. The continuous engine operation time before the sleep function is turned on (before the start of an intermittent power saving operation) is determined by the increase value of the operation time counter, and the duty D is determined according to this continuous operation time. in this case, there is no need to install a battery voltage input circuit.

According to the aforementioned, in 21 As illustrated, the power saving operation is performed by processing in the communication terminal 56 is done, which is advantageous in that other devices, wiring noise and the like have no influence. The construction after 22 can instead of building in 21 be used. That is, the power saving operation control function with the engine ignition switch turned off 64 via another device to the communication terminal 56 can be directed, for example, the communication control 56 so that the electrical connection between the communication terminal 56 and the battery 63 through the communication control 54 can be controlled intermittently on and off.

As in 22 is the energy terminal of the communication terminal 56 via a power source switch 65 electrically with the battery 63 connected. When the power source switch 65 is off, is the electrical connection between the communication terminal 56 and the battery 63 interrupted.

The energy terminal of the communication controller 54 is electric with the battery 63 connected. The operating signal S1 of the engine ignition switch 64 gets into the communication control 54 entered. Further, a signal S3 indicating the communication state is received from the communication terminal 56 in the communication control 54 entered. If the communication terminal 56 and the communications satellite 9 communicate, the communication state signal S3 is switched to the logic level "1".

A software timer is in the communication controller 54 saved, or a hard ware timer is provided therein, and a power source switch driving signal S2 is applied to the power source switch 65 output.

The communication control 54 performs a processing similar to that of 7 by.

7 (a) shows the operating signal S1 of the engine ignition switch 64 that from the communication terminal 56 in the communication control 54 is entered, 7 (b) shows the communication state signal S3 from the communication terminal 56 in the communication control 54 is entered, and 7 (c) shows the power source switch driving signal S2 generated by the communication controller 54 to the power source switch 65 is issued.

Similar to the structure according to 21 When the engine is stopped (signal S1 off), activation of the communication terminal becomes 56 after a predetermined power stroke D (signal S2 on, off) off and on. When the engine is in operation (signal S1 on), said sleep function is forcibly canceled, such that during engine operation the communication terminal 56 is always activated (signal S2 on). If communication occurs (S3 on) while the engine is stopped, the communication terminal remains 56 activated until the communication is complete (S2 on).

It should be noted that the power stroke D in a similar manner according to the terminal voltage of the battery 63 or the engine operating time can be changed.

Various changes can be made to this embodiment. These changes are described below with reference to the 13 . 23 . 24 and 25 described.

The power stroke D may be according to the position information of the mobile work machine 31 to be changed.

23 shows an embodiment in which the power stroke D corresponding to that of the mobile work machine 31 is changed with respect to a predetermined range traveled distance.

23 (a) shows a situation in which the activation period T is shortened and the duty cycle D is increased when the mobile work machine 31 from a set area 117 deviates on a map.

Most automobiles and the like usually move themselves. Mobile work machines 31 However, such as construction machines rarely move by a drive over long distances and are almost always moved by loading on a semi-trailer or the like with the engine off. In this case, not only mobile machines 31 on the semitrailer 35 loaded, which is from the side of the terminal 11 but they could also be stolen and loaded on an unmanaged semi-trailer and illegally transported overseas, or the like. A mobile work machine 31 can also without permission with the semitrailer 35 incorrectly transported to an administrator-prohibited workstation.

It is therefore necessary to the driving route of the mobile work machine 31 to manage and monitor when the engine operation of the mobile work machine 31 is stopped by at the terminal 11 the movement position of the mobile work machine 31 in response to a request from the terminal 11 is displayed, avoiding energy consumption during communication.

For this purpose, a predetermined area 117 in which, under normal conditions, the mobile work machine 31 should be located on a map in a screen of the terminal. This set area 117 is, for example, the administrative area of an administrator on the side of the terminal 11 , an employment authorized by the administrator or the like.

The communication terminal 56 the mobile work machine 31 is intermittently activated and deactivated in accordance with the duty cycle D (= (τ / T) × 100%), as previously in 7 shown. At a time when the power saving mode is turned off (the power source switch driving signal S2 is turned on) and the communication terminal 56 is activated, as in 7 (c) shown, a signal indicating the current position of the mobile work machine 31 indicates (and which may also include mobile body information such as the operating hours counter value, the remaining amount of fuel, the battery voltage, and vehicle fault codes) from the communication terminal 56 on the communications satellites 9 in response to a request from the terminal 11 transfer. As a result, successive movement positions of the mobile work machine 31 at the terminal 11 which serves as a display receiver terminal.

The position of the mobile work machine 31 is through the GPS sensor 57 captured as in 2 shown. In this case, if the energy consumption of the GPS measuring devices (GPS antenna 59 , GPS sensor 57 and communication control 54 ) is low, these GPS measuring devices can be directly electrically connected to the battery and operated constantly. When the power consumption of the GPS meters is high, the sleep function is turned on and, similar to the communication terminal 56 , an energy-saving operation is performed intermittently so that the GPS measurement devices are operated only and positions are measured only when the power-saving operation is turned on (during the activation of the communication terminal 56 ).

In the mobile work machine 31 Be the ones through the GPS sensor 57 detected position and the limit position of the set range 117 and processing for changing the activation period T according to the comparison result is performed.

23 (d) shows a situation in which the activation period T corresponding to the position of the mobile work machine 31 with respect to the given area 117 is changed (elapsed time).

When the mobile work machine is in position A or B within the normal given range 117 is located as in the 23 (a) is shown, the activation period T is set to a maximum period T1.

When the mobile work machine 31 however, the limit position C of the normal predetermined range 117 achieved, it is found that the mobile work machine 31 deviates from the normal given range and an irregular situation has occurred (theft, movement outside the permissible range). The activation period T is then reduced from the maximum period T1 to a shorter period T2 to obtain detailed information regarding the travel route (see 23 (d) ).

Reach the mobile machine 31 the position D, from the limit position of the normal predetermined range 117 is spaced by a predetermined distance L0, the activation period T is set to a time T3 which is even shorter than the period T2, to obtain even more detailed information regarding the movement route (see 23 (d) ). It then becomes more distant from the normal given range 117 the activation period T is successively reduced to T4 (<T3) ..., and may be set to a period of time 0 (duty cycle D = 1).

As in the graph of 23 (c) As shown, the activation period T may increase with the distance L from the limit position of the normal predetermined range 117 increasingly be reduced.

With the shortening of the activation period T of the communication terminal 56 will be the reactions to requests from the terminal 11 more quickly. When the mobile work machine 31 performs an automatic transmission, as explained below, the transmission intervals of the mobile body information containing position information become shorter.

With increasing distance of the mobile work machine 31 from the normal given range 117 Thus, an increasingly accurate movement route (a movement route in which the time interval between each displayed movement position is short) is displayed on a screen of the terminal 11 displayed serving as the display receiver terminal. As a result, swift and appropriate action can be taken against an irregular event, such as theft or out-of-range movement. With increasing distance of the mobile work machine 31 from the normal given range 117 the power stroke D takes the on / off activation of the communication terminal 56 to, and thus can closely monitor the irregular situation, while the energy consumption during communication is avoided.

23 (b) shows a situation in which the activation period T is shortened and the duty cycle D is increased while the mobile work machine 31 a predetermined range 118 penetrates on a map.

Similar to the 23 (a) is a predetermined range 118 on a map in a screen of the terminal 11 specified in which the mobile work machine 31 under normal circumstances should not be spent. This predetermined range 118 For example, an irregular area, such as an overseas port where a theft has occurred, may be a hazardous work area, or an illegal work area, such as a nature reserve.

In the mobile work machine 31 Be the ones through the GPS sensor 57 detected position and the limit position of the set range 118 , similar in connection with 23 (a) described, and a processing for changing the activation period T performed according to the comparison result.

23 (d) shows a situation in which the activation period T corresponding to the position of the mobile work machine 31 in relation to the pre given area 118 is changed (elapsed time).

When the mobile work machine is in position A or B within the irregular predetermined range 118 is located as in the 23 (b) is shown, the activation period T is set to a maximum period T1.

When the mobile work machine 31 however, the limit position C of the irregular predetermined range 118 is reached, it is determined that an irregular situation has occurred (theft, movement in a dangerous area), and the activation period T is then set from the maximum period T1 to a shorter period T2 to detailed information regarding the movement route of the mobile machine 31 to obtain (see 23 (d) ).

Reach the mobile machine 31 the position D, which is from the limit position of the irregular predetermined range 118 is spaced by a predetermined distance L0, the activation period T is set to a time T3 which is even shorter than the period T2, to obtain even more detailed information regarding the movement route (see 23 (d) ). Subsequently, with increasing distance from the irregular given area 118 the activation period T is successively reduced to T4 (<T3) ..., and may be set to a period of time 0 (duty cycle D = 1).

As in the graph of 23 (c) As shown, the activation period T may increase with increasing distance L from the limit position of the irregular predetermined range 118 increasingly be reduced.

With increasing penetration of the mobile work machine 31 in the irregular given area 118 Thus, an increasingly accurate movement route (a movement route in which the time interval between each displayed movement position is short) is displayed on a screen of the terminal 11 displayed serving as the display receiver terminal. As a result, swift and appropriate action can be taken against an irregular event such as theft or intrusion into a hazardous area. With continued penetration of the mobile work machine 31 in the irregular given area 118 the power stroke D takes the on / off activation of the communication terminal 56 to, and thus can closely monitor the irregular situation, while the energy consumption during communication is avoided.

It should be noted that this embodiment is not limited to the monitoring of an irregular situation, as in the 23 (a) , (b) is applicable, but also to a case where the routes of the mobile work machine 31 be monitored until the mobile work machine 31 disassembled and disposed of.

In the embodiment of the 23 (a) (b) The activation time T becomes mainly by the distance L from the boundary line of the predetermined ranges 117 . 118 certainly. However, the activation time T can also be determined from the azimuth angle, peripheral geographical information, the moving body type, the moving body usage time, and the like.

As in 24 Further, the duty cycle D may further be set according to the position change amount of the mobile work machine 31 be changed.

The communication terminal 56 the mobile work machine 31 is intermittently activated and deactivated according to the duty cycle D ((τ / T) × 100%), as previously described in 7 shown. At a time when the power saving mode is turned off (the power source switch driving signal S2 is turned on) and the communication terminal 56 is activated, as in 7 (c) shown, a signal indicating the current position of the mobile work machine 31 indicates (and which may also include mobile body information such as the operating hours counter value, the remaining amount of fuel, the battery voltage, and vehicle fault codes) from the communication terminal 56 on the communications satellites 9 in response to a request from the terminal 11 transfer. As a result, successive movement positions of the mobile work machine 31 at the terminal 11 which serves as a display receiver terminal.

The position of the mobile work machine 31 is through the GPS sensor 57 captured as in 2 shown. In this case, if the energy consumption of the GPS measuring devices (GPS antenna 59 , GPS sensor 57 and communication control 54 ) is low, these GPS gauges can be directly powered electrically with the battery 63 be connected and operated constantly. When the power consumption of the GPS meters is high, the sleep function is turned on and, similar to the communication terminal 56 , an energy-saving operation is performed intermittently so that the GPS measurement devices are operated only and positions are measured only when the power-saving operation is turned on (during the activation of the communication terminal 56 ).

In the mobile work machine 31 Be the ones through the GPS sensor 57 detected position and the limit positions of circles 119 . 120 .., each having a radius S centered on the position detected during the previous activation time, and processing for changing the activation period T according to the comparison result.

24 (b) shows a situation in which the activation time T is changed depending on whether the mobile work machine 31 from the circles 119 . 120 ... deviated.

Like in the 24 (a) shown, first, a position A of the mobile machine 31 from the GPS sensor 57 captured, and a circle 119 with a radius S (km) centered on a position A is given on the map. The original activation time T is set as the maximum time period T1. The communication terminal 56 is therefore activated after the period T1. The one from the GPS sensor 57 Position recognized at this time is assumed to be position B in the circle 119 lies.

In this case, the activation time T remains the maximum time period T1. The communication terminal 56 is activated again after the period T1 and that of the GPS sensor 57 Position detected at this time is assumed to be position C, which is outside the circle 119 lies. In this case, a circle 120 with a radius S (km) centered on the position C given on the map, and the activation time T is changed to a time T2 shorter than the time T1.

The communication terminal 56 is then activated after the period T2. The one from the GPS sensor 57 Position detected at this time is assumed to be position D within the circle 120 lies. In this case, the activation time T remains the time period T2. The communication terminal 56 is activated again after the period T2 and that of the GPS sensor 57 Position detected at this time is assumed to be position E outside the circle 120 lies. In this case, a circle 121 with a radius S (km) centered at the position E in the map, and the activation time T is changed to a shorter time T3 shorter than the time T2. The communication terminal 56 will be activated again after the time period T3, and that of the GPS sensor 57 Position detected at this time is assumed to be position F outside the circle 121 lies. In this case, a circle 122 with a radius S (km) centered at the position F in the map, and the activation time T is changed to a shorter time T4 shorter than the time T3. The communication terminal 56 will be reactivated after the time period T4, and that of the GPS sensor 57 Position detected at this time is assumed to be position G within the circle 122 lies. In this case, the activation time T returns from the time T4 to the longer time T3 (see FIG 24 (b) ).

It should be noted that in the embodiment according to 24 (a) areas as circles 119 . 120 are specified with a radius S, but instead areas can be specified as squares with a side S.

An advantage in the case of square areas is that when compared by the GPS sensor 57 during the current activation time recognized current position of the mobile machine 31 with the limit position of an area centered on the position recognized during the previous activation time, it can be easily determined whether the mobile work machine is moving 31 out of range without having to perform complicated computational processing by subtracting latitudes and lengths on the map.

The areas 119 . 120 ... from 23 (a) can also have a different shape than a circle or a square. For example, the areas may be ellipses or rectangles where either the width or the length is greater. It can also ellipses or rectangles are used, in which the direction of travel of the mobile machines 31 is long, can also be used. In this case, findings may be that the mobile work machine 31 deviated from the range, be hit faster and more accurately.

The size of the areas 119 . 120 ..., or in particular the value of the radius S (km) in the case of a circular area, can be changed according to the amount of movement.

In the case of 24 becomes with increasing driving speed of the mobile working machine 31 the activation time T is correspondingly changed and a detailed movement route (a movement route in which the time interval between each displayed movement position is short) is displayed on a screen of the terminal serving as a display terminal terminal 11 displayed. In this way, a situation in which a mobile work machine 31 has completed a job at a job, and moves to the next job, on the side of the terminal 11 are accurately recorded, and as a result, the work efficiency of task management and transportation management is greatly improved. With increasing Fahrge speed of the mobile work machine 31 the working cycle D of the on / off activation of the communication terminal increases 56 and thus, a simultaneous accurate monitoring of the mobile work machine 31 be achieved in the movement and avoiding energy consumption during communication.

According to the embodiment 24 the activation time T is changed according to the fact that the successively predetermined ranges 119 . 120 ... are exceeded or not. As in the graph of 25 shown, the driving speed V of the mobile machine 31 in each activation time T, so that the activation time T is changed according to the magnitude of this calculated velocity V. At the in 25 illustrated embodiment, as in the embodiment of 24 , the position of the mobile work machine 31 through the GPS sensor 57 every time the communication terminal is activated 56 recognized.

The vehicle speed V is then calculated according to the following expression: V = (position detected during current activation time - position detected during previous activation time) / current activation time T

The relationship between the vehicle speed V and the activation time T is in the graph in FIG 25 shown. When the vehicle speed V is sufficiently low, or in other words, when V1 (= 3 km / h) or less, the activation time T is set to the maximum time T1 (= 10 minutes). As the vehicle speed V increases from V1 in the direction of a vehicle speed V2 (= 50 km / h) during transport through the semitrailer, the activation time T becomes shorter. When the vehicle speed V reaches the vehicle speed V2, the activation time T is zero (power stroke D is 1), that is, the communication terminal 56 enters a state of constant communication.

The activation time T is determined by an activation time T from the curve of 25 is determined according to the vehicle speed V, which is determined according to the aforementioned calculation expression.

With increasing driving speed V of the mobile work machine 31 becomes the activation time T shorter and a more detailed trajectory (a movement route in which the time interval between each displayed movement position is short) is on a screen of serving as a display terminal terminal 11 displayed. In this way, a situation in which a mobile work machine 31 has completed a job at a job, and moves to the next job, on the side of the terminal 11 be accurately detected. Furthermore occurs at the speed V2 of the transporter (semitrailer) 35 the communication terminal 56 in a state of permanent activation, so that the moving position of the mobile work machine 31 is displayed at any time, and it is possible in this way, a situation in which, for example, the one with the mobile work machine 31 loaded semitrailers 35 driving on a forbidden highway, on a screen of the terminal 11 constantly monitored. As a result, the work efficiency of task management and transportation management is greatly improved. With increasing driving speed of the mobile work machine 31 the working cycle D of the on / off activation of the communication terminal increases 56 , allowing simultaneous accurate monitoring of the mobile work machine 31 be achieved in the movement and avoiding energy consumption during communication.

In the embodiment described above, the activation of the communication terminal takes place 56 at fixed times T. The activation of the communication terminal 56 However, it can also be intermittent as soon as a certain point in time has been reached.

For example, the communication terminal 56 be activated when a certain time has been reached, to which the communication between the communication satellites 9 and the mobile work machine 31 is cheap. This specific time corresponds to the position (height) of the communications satellite 9 ,

13 (a) shows the positional relationship between the communications satellite 9 and the mobile work machine 31 , barriers to communication 123 , such as mountains and buildings, are located in the communication path (wireless communication line 5 ) between the communications satellite 9 and the mobile work machine 31 ,

If the communication satellite 9 is at high altitude (when the maximum elevation angle is large), the obstacles cause 123 few communication impediments and the communication status becomes favorable. If the communication satellite 9 reaches a high altitude, becomes the communication terminal 56 enabled and communication with the communications satellites 9 carried out.

It should be noted, however, that to activate the communication terminal 56 Informa tions regarding the position of the communications satellite 9 in the air in the mobile work machine 31 must be stored.

The air position information about the communications satellite 9 change every day. Therefore, with daily storage of the air position information in the memory of the mobile work machine 31 Problems with regard to a lack of storage capacity and the memory allocation result.

Therefore, in this embodiment, as in FIG 13 (a) shown, a predetermined amount of air position information 124 from the communications satellite 9 to the mobile work machine 31 over the wireless communication line 5 transfer.

Inside the communication terminal 56 the mobile work machine 31 a clock is provided. By comparing the received air position information 124 and the time measured by the clock, it is determined if the communication terminal 56 should be activated.

13 (b) shows the aerial position information of the communication satellite 9 on a specific day.

In 13 (b) Specifies "AOS" the time and the azimuth angle, to or below the communication satellite 9 appears on the horizon, "MEL" indicates the time and azimuth angle to or below which the communication satellite reaches the maximum elevation angle, and "LOS" indicates the time and azimuth angle to and below the communication satellite 9 disappears behind the horizon. The course of the communications satellite 9 over the surrounding parts is in the 13 (c) shown.

In the communication terminal 56 the mobile work machine 31 becomes a processing for activating the communication terminal 56 executed when a maximum elevation angle equal to or greater than a predetermined threshold (for example, 45 °), from the air position information 124 in the 13 (b) are shown, or in other words: at the times 4:33 and 16:28, to which maximum elevation angles of 66 ° and 54 ° are achieved. That is, when the specified times 4:33 and 16:28 are reached, the main power supply circuit of the communication terminal becomes 56 and a signal indicative of mobile body information is sent to the communication satellites 9 over the wireless communication line 5 transfer.

New air position information data 124 are then from the communications satellite 9 For example, every day at this specific time to the mobile machine 31 over the wireless communication line 5 transfer. In this way, the in the memory of the mobile work machine 31 stored content of the air position information 124 updated.

According to this embodiment, as in 13 (a) represented, the communication terminals 56 activated as soon as a specific time is reached, to which the communication between the communication satellites 9 and the mobile work machine 31 can be carried out conveniently. As a result, energy savings are achieved and communication between the communications satellite 9 and the mobile work machine 31 is performed reliably. Because the air position information 124 Further, from outside are received via communication devices, there are no problems regarding lack of storage capacity and memory consumption on the mobile work machine side 31 on.

Also in this embodiment, the activation of the communication terminal takes place 56 intermittently at a predetermined time T, however, this activation time T can be arbitrary, for example, on the part of the administrator terminal 11 be modified. In this case, as described below, an electronic mail including modification data indicating modification of the activation time T is received from the terminal 11 to the mobile work machine 31 transfer, being the mobile work machine 31 serves as a mail address. The modification data written in the electronic mail is then stored in the communication terminal 56 the transmission receiving mobile work machine 31 whereupon the activation time T is modified according to the content of the modification data with the content of the modification data.

For example, if the operating hours counter of the mobile work machine 31 exceeds a predetermined value (in the case of aging), the activation time T is shortened to observe the situation at short intervals. When the mobile work machine 31 is awarded to a particular user (if monitoring is not required) or if the vehicle is not in use for an extended period of time (when it is clear that operation is stopped), the activation time T is extended to extend the monitoring intervals and reduce unnecessary energy consumption and communication costs. Identical activation times T for several working mobile bodies forming a group can be modified at once.

According to this embodiment, the Activation time T by a remote operation on the side of the terminal 11 be modified while monitoring the conditions of the mobile body and the peripheral conditions. Thus, there is no need for a worker to adapt to the respective positions of the mobile body 31 . 32 ... to perform a modification of the activation time T, which significantly reduces the workload.

According to the embodiment described above, communication is between the plurality of terminals 11 . 12 ... and the mobile bodies 31 to 35 , such as construction machines, possible, which are not in operation for a long period of time, even if the engines of the mobile body 31 to 35 are switched off, so to requirements on the part of the terminals 11 . 12 ... answers can be issued. Furthermore, unnecessary power consumption is avoided.

This embodiment in which the communication power supply is intermittently turned on is not applicable to the communication system in FIG 1 limited and can be applied to any communication system. This embodiment is applicable to any communication system including at least two communication stations, so that communication between the two communication stations is possible.

However, in the aforementioned embodiment, the case is provided that the mobile body information is transmitted to a display receiver terminal (for example, terminal 12 ) is displayed only when a request for mobile body information from a request originating terminal (e.g., terminal 11 ) has been sent to a requesting mobile body (for example, the mobile work machine 31 ).

at the following embodiment when parameters in a mobile body have a specific value reach, specific mobile body information automatically transfer, and this specific mobile body information are displayed on the side of the terminal when viewed from the terminal side no request goes out.

To this embodiment can be the appearance of an irregular State (for example, theft, malfunction, etc.) in one mobile body which is not managed from the terminal side or monitored can be, and the operating or resting state of the mobile body can be accurately detected.

Here, as in 2 represented a parameter inside the mobile work machine 31 for example, starting the engine by a predetermined sensor (eg, a sensor that detects the voltage of an alternator) among a plurality of sensors 62 recognized. As noted previously, the detection signal of this sensor is from the electronic controller 53 written in a frame signal and along the signal line 52 transferred to the communication terminal 56 via the communication control 54 to be entered. It should be noted that another known method than that described may be used as long as the on / off state of the engine in the communication terminal 56 can be monitored.

26 (a) shows a signal indicating the state of starting the engine, which in the communication terminal 56 the mobile work machine 31 is entered. 26 (a) shows the state of starting the engine in the mobile work machine 31 at any time t one day (from 6:00 to the next time 6:00). The logical level "1" corresponds to the state in which the engine is running (start), while the logic level "0" corresponds to a state in which the engine operation is stopped.

An automatic transmission from the mobile work machine 31 can be done at any engine start time, as in 26 (b) shown.

That is, when the engine is started at time t1, as in FIG 26 (a) and a signal indicative of starting the engine into the communication terminal 56 is entered, specific mobile body information, for example, the current position of the mobile work machine 31 included in an electronic mail, this signal acts as a trigger, as represented by the arrow e, and the electronic mail is sent to the communications satellites 9 transfer. The recipient email address of this electronic mail is called the server terminal 21 set. If the communication terminal 56 due to the aforementioned energy-saving operation, the electronic mail is transmitted to the communication terminal after starting the engine 56 forcibly activate.

If the server terminal 21 when the administrator-side terminal is set, are displayed on a screen of the administrator-side terminal 21 successive positions of the mobile work machine 31 displayed each time the engine is started. As a result, the administrator can view the location-related history of the mobile work machine 31 every time you start the engine, and thus the occurrence of irregular situations (such as theft) in the mobile work machine 31 be detected, which can not be managed and monitored at all times, and the operating and resting state of the mobile machine 31 can be detected accurately.

The electronic mail can be from the mobile work machine 31 to the recipient's e-mail address of another terminal (Terminal 11 , Terminal 12 ... and so on).

Another transmission from the mobile work machine 31 can also be done the first time the engine is started on a day, as in 26 (c) shown.

That is, when the engine is started at time t1, as in FIG 26 (a) is shown in the communication terminal 56 entered a start signal indicating the starting of the engine. Inside the communication terminal 56 If there is a clock, it is determined if this start signal is the first input signal of the day (from 6:00 to the next time 6:00). Only when it is determined that the input start signal is the first input start signal of the day is the present position of the mobile work machine 31 incorporated in an electronic mail with the start signal as a trigger, as shown by the arrow f, and the electronic on the communication satellites 9 transfer. Thus, the location-related history of the mobile work machine becomes 31 in a similar way to the administrator-side terminal. In this embodiment, the interval of the automatic transmission is at least one day, and so the communication costs compared with the in 26 (b) be reduced illustrated case.

It it should be noted that here the automatic transmission only performed the first time the engine is started in one day. However, this period can be set arbitrarily, and the automatic transmission For example, it can only be done the first time the engine is started in a week respectively.

The automatic transmission of pages of the mobile machine 31 can also be done within a day when starting the engine during a certain time window (for example, 18:00 to 6:00) 26 (d) shown.

Specifically, if the engine is started at a time t4 within the time window of 18:00 to 6:00, as in 26 (a) and a signal indicative of starting the engine into the communication terminal 56 is entered, the current position of the mobile work machine 31 in an electronic mail with this signal as a trigger involved, as shown by an arrow i, whereupon the electronic mail to the communication satellites 9 is transmitted. In this way, the location-related history of the mobile work machine becomes 31 in the specific time window similarly displayed on the administrator side terminal. The specific time window 18:00 to 6:00 (at night) is a time window in which normal mobile work machines, such as construction machines, are not in operation. It is also a time window in which no movement is performed for a long time. When the engine is started and the mobile work machine 31 During this specific period, some kind of irregularity, such as theft, may have occurred. Because the positional history of the mobile work machine 31 during the specific time window is displayed on the administrator-side terminal, it can be determined whether an irregularity in the mobile work machine 31 occurred by monitoring the screen.

An automatic transmission from the mobile work machine 31 may also occur if the engine stops due to an irregularity, as in 26 (e) shown.

This is the occurrence of an irregularity in the mobile machine 31 For example, "high engine speed", "high engine exhaust temperature", "high cooling water temperature", "low battery voltage" or "low fuel amount" by a predetermined sensor of the sensor group 62 recognized as in 2 shown. As mentioned above, the detection signal of this sensor is from the electronic controller 53 as the error code (for example, "Fault element: low fuel quantity") written in a frame signal and over the signal line 52 transferred to the communication controller 54 into the communication terminal 56 to be entered. It should be noted that a known method different from this method may be used as long as vehicle noise is present at the communication terminal 56 can be monitored.

When the engine operation is stopped at time t2, as in 26 (a) is shown, a stop signal indicating the stopping of the engine in the communication terminal 56 entered. In this state, the aforementioned error code in the communication terminal 56 entered. Then, it is determined whether the stop signal and the error code have been input simultaneously. When the stop signal and the error code have been input simultaneously, it is determined that the engine has stopped due to an abnormality (disturbance) and the current position of the mobile work machine 31 will be in an electroni eMail with this stop signal as a trigger included, as indicated by the arrow g, whereupon the electronic mail to the communication satellites 9 is transmitted. The position of the mobile work machine 31 is then similarly displayed on the administrator side terminal. According to this embodiment, the position of the mobile work machine 31 displayed on the terminal side only when the engine is stopped due to the detection of an abnormality, and thus the position can be accurately detected at the time of occurrence of the trouble. As a result, rapid action can be taken against the irregularity and damage to the mobile work machine 31 can be minimized.

Instead of an automatic transmission can easily perform when an irregularity occurs a specific fault element (a serious disturbance element) under the fault elements (Error codes) are set in advance, allowing automatic transmission only occurs when this serious incident occurs.

An automatic transmission from the mobile work machine 31 can also be done when starting the engine after troubleshooting, as in 26 (f) shown.

When the engine is started at time t3, as in 26 (a) is shown, a start signal indicating the starting of the engine, in the communication terminal 56 entered. In this case, the said error code also becomes the communication terminal 56 entered. When a service person or the like takes prescribed measures against the failure to correct the abnormality (trouble), the error code no longer enters the communication terminal 56 entered. By the time the error code is no longer entered, the communication terminal will be displayed 56 determined whether the engine was started. When the engine starts at the time when the error code is no longer input, it is determined that the abnormality (disturbance) has been eliminated and the engine has been started, and hence the current position of the mobile work machine 31 in an electronic mail with the start signal as a trigger involved, as indicated by an arrow h, whereupon the electronic mail to the communication satellites 9 is transmitted. Thus, the position of the mobile work machine becomes 31 in a similar way to the administrator-side terminal. In this embodiment, the position of the mobile work machine becomes 31 is displayed on the terminal only when the engine is started following the elimination of a malfunction, and therefore, the position at the point where the malfunction is appropriately treated can be accurately detected.

The automatic transmission of specific mobile body information by the mobile work machine 31 For example, a business card until 20:00 that day (storage indicating the times at which the engine was started and stopped) may occur at a particular time (for example, 24:00 (0:00)). In this way, a daily operating map is displayed on a screen of the terminal, as in the 30 shown.

Specific mobile body information may also be available from the mobile work machine at a certain time once in a few days 31 be transferred (for example at 24:00 every three days).

Specific mobile body information may also be automatically generated by the mobile work machine at a particular time on any particular day of the week (for example, at 24:00 every Saturday) 31 be transmitted.

By transmitting specific mobile body information at a specific time as described above, specific mobile body information regarding the mobile work machine can be obtained 31 be read periodically from a screen of the terminal.

Further, specific mobile body information (for example, "hour meter", "vehicle frame alarm 1" (error code 1), "vehicle frame alarm 2" (error code 2), "battery voltage", "engine water temperature", engine speed "," pump pressure ", or" amount of oil ") can be automatically set be transmitted when the cumulative value of the operating time of the mobile work machine 31 reaches a specific cumulative operating time value, for example, when the absolute value of the operating hours counter reaches 100 hours, 300 hours and 500 hours.

By such transfer specific mobile body information at a specific cumulative operating time value, advance information can be provided to carry out a mandatory routine inspection on a screen of the Terminals are obtained. Because an automatic transmission according to a Operating time transition (Last) performed can be meaningless communication during vehicle rest periods be avoided, and so can the communication costs are lowered.

Further, specific mobile body information (e.g., "hour meter", "vehicle frame alarm 1" (error code 1), "Fahrzeu Grahmenalarm 2 "(fault code 2)," battery voltage "," engine water temperature ", engine speed", "pump pressure", or "amount of oil") are automatically transmitted when the cumulative value of the working machine operating time 31 increases by a certain amount, for example, as soon as the runtime counter's slew rate reaches 100 hours following the previous automatic transmission (or as soon as the slew rate reaches 500 hours). It should be noted that the slope value of the operating hours counter is in accordance with the service round trip time of the service vehicle 34 can be adjusted.

By thus transmitting specific mobile body information every time the cumulative operating time value is increased by a specific amount, advance information for performing a prescribed routine inspection on a screen of the terminal can be obtained. When displayed on the administrator-side terminal, itinerary instructions can be easily communicated to the service vehicle 34 be issued. When displayed on the service person's terminal, a mobile work machine requiring servicing work can be easily specified, and service work can be performed by the service vehicle 34 be done quickly. Further, since the automatic transmission is performed according to an operation time transition (load), meaningless communication during vehicle rest periods can be avoided, and thus the communication cost can be lowered.

Numerous modifications may be made to this embodiment. These are now with reference to the 9 . 10 . 11 . 12 and 14 described.

This automatic transmission can be performed at the time when the position of the mobile work machine 31 changes.

The position of the mobile work machine 31 is through the GPS sensor 57 , as in 7 represented, recognized. The recognition result of the GPS sensor 57 gets into the communication control 54 entered. If in the communication control 54 it is stated that this is the position of the mobile work machine 31 has changed, information about the position after the change as transmission data to the communication terminal 56 transfer. An electronic mail into which the position information is written is then automatically transmitted from the communication terminal 56 via the satellite communication antenna 58 transfer.

By thus transmitting the position information as soon as the position of the mobile work machine 31 Can change the motion history of the mobile work machine 31 be read on the screen of a terminal.

The automatic transmission can also be done when the mobile work machine 31 from a certain given area 129 deviates, as in 10 shown.

The position of the mobile work machine 31 is from the GPS sensor, as in 2 represented, recorded. The detection result of the GPS sensor 57 gets into the communication control 54 entered. Position information regarding a job is in the communication controller 54 saved. The default range 129 The job is a circle with a radius S (km). The recognized position of the mobile work machine 31 and the limit position of the predetermined range 129 are then compared, and it is determined whether the mobile work machine 31 from the given area 129 differs. When the mobile work machine 31 the limit position 3 of the given range 129 reached, the currently valid position information on the mobile Ar beitsmaschine 31 to the communication terminal 56 transmitted as transmission data. An electronic mail containing the position information is then automatically transmitted from the communication terminal 56 via the satellite communication antenna 58 transfer.

By transmitting the position information as soon as the mobile work machine 31 from the given area 129 deviates (if the mobile machine 31 passing a predetermined position), it is easy to monitor, on a screen of a terminal, the operation of the mobile work machine 31 within the workplace. The default range 129 is not limited to a fixed area such as a job, but may be an area that points to a previous position of the mobile work machine 31 is centered. In other words, the predetermined range may be updated over time.

Furthermore, the shape of the predetermined area 129 is not limited to a circle, but may be given any shape, such as an ellipse, a square, a rectangle or an ellipse or a rectangle, in which the direction of movement of the mobile machine 31 as the long side is given.

The default range 129 in 10 can also be considered a normal range 117 from 23 (a) be given appropriate area.

An automatic transmission may also be performed when the amount of change of the moving position of the mobile work machine 31 exceeds a predetermined value, as in 10 shown.

The position of the mobile work machine 31 is from the GPS sensor 57 , as in 2 represented, recognized. The recognition result of the GPS sensor 57 gets into the communication control 54 entered with a constant sampling period. The driving speed V of the mobile Arbeitsma machine 31 is calculated based on the difference value between the previous detected position and the current detected position and the sampling time. The driving speed V of the mobile working machine 31 and the set value V2 ( 25 ) are then compared, and it is determined whether the speed V of the mobile work machine 31 exceeds the set value V2. When the speed V of the mobile machine 31 exceeds the set value V2, the position information of the mobile work machine becomes 31 at this time to the communication terminal 56 transmitted as transmission data. An electronic mail containing the position information is then automatically transmitted from the communication terminal 56 via the satellite communication antenna 58 transfer.

By such transmission of position information when exceeding the set value V2 by the speed V of the mobile machine 31 can be a monitoring of the state of motion of the mobile machine 31 be done easily on a screen of a terminal. Mobile work machines 31 like construction machines move at extremely low speeds. When the set value V2 is set to a high speed which the mobile work machine 31 can not reach self-propelled, for example, the speed of a traveling on a highway semi-trailer 35 , can be found that the mobile work machine 31 on a semi-trailer 35 is transferred when the speed V of the mobile machine 31 exceeds the set value V2. Furthermore, if the mobile work machine 31 is transported by a semi-trailer at a time and under circumstances when transportation is not usually performed, the occurrence of an abnormality such as a theft can be detected, and appropriate measures can be taken quickly.

An automatic transmission can also be done when the service vehicle 34 in certain predetermined areas 125 . 126 invades, as in 9 shown.

The position of the service vehicle 34 is from the GPS sensor 57 recognized as in 2 shown. The recognition result of the GPS sensor 57 gets into the communication control 54 entered. Position information regarding the receiver position 126 the mobile work machine 31 which is the subject of the service, and an area 125 are not allowed to be penetrated in the communication control 54 saved. The default range 126 The receiver position is a circle with a predetermined radius that is at the position of the mobile work machine 31 is centered. The area 125 , which can not be penetrated, is, for example, a road that is restricted passable due to heavy rain, or an area with unsuitable ground.

The recognized position of the service vehicle 34 and the limit positions of the predetermined ranges 125 . 126 are then compared, and it is determined if the service vehicle 34 in the given area 125 or 126 has penetrated. If the service vehicle 134 the limit position H or I of the predetermined range 125 or 126 achieved while along the route 127 or 128 drives, the position information of the service vehicle 34 at this time to the communication terminal 56 transmitted as transmission data. An electronic mail containing the position information is then automatically transmitted from the communication terminal 56 via the satellite communication antenna 58 transfer.

By transmitting position information when the service vehicle 34 in the given area 125 or 126 penetrates (if the service vehicle 34 exceeds a predetermined position) can be easily monitored on a screen of the terminal, whether the service vehicle 34 has reached the recipient or has entered the prohibited area. In other words, an administrator can use the screen of the administrator-side terminal to determine that the service vehicle 34 the receiver position 126 He has reached and taken the service work, and he can also find that the service vehicle 34 in the inadmissible area 125 penetrated and is in a dangerous situation. As a result, appropriate work instruction data (the message "Return to Completion" or "Avoid Invalid Area") may be sent from the administrator side terminal to the service vehicle as described 34 be issued (see 4 ).

It should be noted that the predetermined range of the receiver position 126 is not limited to a circle and can be specified with any shape, such as an ellipse, a square or a rectangle.

Furthermore, the predetermined ranges 125 . 126 to 9 as areas that are the irregular area 118 to 23 (b) correspond.

The automatic transmission may also be performed when the amount of data to be transmitted is equal to or exceeds a predetermined value, as in 11 shown.

In a communication system using a pay per use system, the communication charge to be paid per use is a fixed monthly amount up to a certain amount of data Do, as in 11 (a) shown. If the data amount D exceeds a predetermined value D0, an additional amount corresponding to the amount of the additional data must be paid.

For this purpose, certain mobile body information to be transmitted automatically from the mobile work machine side 31 in the communication control 54 collected and accumulated. The accumulated data amount D and a predetermined value (80% of D0) are in the communication control 54 compared. When the accumulated data amount D is equal to the predetermined value (80% of D) as in 11 (b) As shown, the accumulated mobile body information becomes the communication terminal 56 transmitted as transmission data. An electronic mail containing this mobile body information is then automatically transmitted from the communication terminal 56 via the satellite communication antenna 58 transfer.

By such transfer of mobile body information as soon as the automatically transferred Data set D corresponds to (or exceeds) a predetermined value, can the maximum mende of mobile body information within the fixed amount on a screen of the terminal.

An automatic transmission may also be performed when the fuel quantity is equal to or lower than a predetermined value, as in 12 (a) shown.

The fuel quantities are from the sensor group 62 the mobile work machine 31 and then to the communication controller 54 transfer. The detected amount of fuel and a predetermined value are in the communication control 54 compared. As soon as the detected fuel quantity corresponds to the predetermined value, as in 12 (a) shown, mobile body information ("position", "amount of fuel") to the communication terminal 56 transmitted as transmission data. An electronic mail containing this mobile body information is then automatically transmitted from the communication terminal 56 via the satellite communication antenna 58 transfer.

By thus transferring mobile body information as soon as the fuel amount is equal to or less than a predetermined value, the time of filling fuel can be read on a screen of the terminal. As a result, suitable work order data (a "refill fuel" message) from the administrator-side terminal na may be the service vehicle 34 which is a routine refueling work similar to those in the 3 and 4 performs.

An automatic transmission can also be done as soon as the voltage of the battery 63 a predetermined value or falls below a predetermined value, as in 12 (b) shown.

Voltage values of the battery 63 be from the sensor group 62 in the mobile work machine 31 and then to the communication controller 54 transfer. The detected battery voltage and a predetermined value are in the communication control 54 compared. As soon as the detected battery voltage corresponds to the specified value, as in 12 (b) represented, mobile body information ("position", "battery voltage") to the communication terminal 56 transmitted as transmission data. An electronic mail containing this mobile body information is then automatically transmitted from the communication terminal 56 via the satellite communication antenna 58 transfer.

By thus transmitting mobile body information as soon as the voltage of the battery 63 a predetermined value (or falls below a predetermined value), the time for a maintenance and inspection, such as charging or replacing the battery 63 be read from a screen of a terminal. As a result, appropriate job data (a "check battery" message) may be sent from the administrator-side terminal to the service vehicle 34 on a the 3 and 4 be transmitted in a similar manner. If based on the screen of the terminal is determined that the battery 63 near the state of discharge, a request to turn on the sleep function may be transmitted so as to communicate with the mobile work machine 31 only intermittent, whereby a further battery discharge can be avoided.

It can also be provided that an automatic transmission not done will, if the previously transmitted Mobile body information and the present automatically transmitted Mobile body information have the same content.

As in 2 is shown, the occurrence of an irregularity in the mobile work machine 31 For example, "high engine speed", "high engine exhaust temperature", "high cooling water temperature", "low battery voltage" or "low fuel amount" by a predetermined sensor of the sensor group 62 recognized. As previously mentioned, the detection signal of this sensor is from the electronic controller 53 as the error code (for example, "Fault element: low fuel quantity") written in a frame signal and over the signal line 52 transferred to the communication controller 54 into the communication terminal 56 to be entered.

The previous automatically transmitted error code and the currently entered error code are in the communication control 54 compared. Only when the contents of the preceding automatically transmitted error code and the current inputted error code are different from each other, the current inputted error code is sent to the communication terminal 56 transmitted as transmission data. An electronic mail containing this mobile body information is then automatically transmitted from the communication terminal 56 via the satellite communication antenna 58 transfer.

There the automatic transmission only occurs when the contents of the previous automatically transmitted Error codes and the current input Error code are different from each other, and an automatic transmission does not take place when the content of the previous automatically transmitted Error codes and the current input Error code are the same, this can be unnecessary multiple transmission the same information is avoided. This is similar Way for the Case that other mobile body information automatically transmitted as an error code become.

In the foregoing embodiment, specific mobile body information is automatically transmitted when a parameter in a mobile work machine reaches a certain value. However, the content of the "parameter" (storage data such as the data amount D and data detected by sensors such as the battery voltage), the "specific value", and "the specific mobile body information" may be arbitrarily set by the administrator terminal (server terminal 21 , Terminal 11 ) to be changed. In this case, as described above, an electronic mail containing modification of the parameter or the like containing modification data from the terminal to the mobile work machine 31 transfer, being the mobile work machine 31 serves as a mail address. The modification data written in the electronic mail is then stored in the communication terminal 56 the transmission receiving mobile work machine 31 whereupon the parameter or the like is modified according to the content of the modification data with the content of the modification data.

For example, the contents of the "parameter", the "specific value" and the "specific mobile body information" are modified such that once the operating hours counter of the mobile work machine 31 exceeds a predetermined value (in case of aging), the monitoring interval is shortened, and when the mobile working machine 31 is awarded to a particular user (when monitoring is not required) or when the vehicle is not in use for an extended period of time (when it is clear that operation is halted), the monitoring interval is extended, thereby avoiding unnecessary energy consumption and Reduce communication costs. It should be noted that identical contents may be modified at once for a plurality of working mobile bodies constituting a group. For example, the "specific mobile body information" can be reduced to only the important monitoring elements.

According to this embodiment, the timing and content of the automatic transmission can be modified by a remote operation on the terminal side while monitoring the conditions of the mobile body and the peripheral conditions. Thus, there is no need for a worker to adapt to the respective positions of the mobile body 31 . 32 ... to carry out a modification work, which significantly reduces the workload.

It be noted that when the automatically transmitted Mobile body information the position of a mobile body affect the width and the length on the map as position information can be transmitted, or it may be a position relative to a specific reference transmitted as position information become.

Further, instead of automatically transmitting a voltage value of the battery 63 as mobile body information, a change amount of the voltage of the battery 63 automatically transmitted be gene.

Of others can Operating load information, the amount of work or the fuel consumption automatically transmitted as mobile body information become.

According to the aforementioned embodiments can specific mobile body information from the point in time when a specific parameter has a specific Value reached, be recognized on a screen of a terminal without a self-performed Request input to the terminal is required. Consequently may be the occurrence of an irregular Situation (for example, theft, disruption, or theft) the like) in a mobile body which is not managed and monitored at all times can be, and the operating state and the idle state of the mobile body can be accurately detected.

This embodiment of the automatic transmission is not on the in 1 shown communication system and can be applied to any communication system. This embodiment is applicable to any communication system having at least two communication stations, so that communication can be made between the two communication stations. The amount of information at the terminal 11 . 12 is to be displayed is very large. Therefore, an embodiment will be described below in which only important information from this large amount of information is preset, and only this important information is displayed summarized on a certain screen. In this embodiment, the occurrence of irregularities by the administrator can be quickly recognized and eliminated.

The following embodiment will be described using the mobile work machine 31 described as a representative example. It is further assumed that the administrator-side terminal is to manage the mobile work machine 31 the terminal 11 is, and that the server of the terminal 11 the server terminal 21 is.

Although this in 2 not shown, is a start locking circuit in the vehicle frame 50 the mobile work machine 31 built-in. The start interlock circuit is formed by a relay and the like, and is between the ignition switch 64 ( 21 ) and a fuel injection device.

When a start lock setting command from the communication controller 54 is output, the start interlock circuit relay is energized so that the start interlock is set. In other words, no fuel is injected even if the ignition switch 64 is turned on, and the engine can not start. Conversely, if a start lock release command from the communication controller 54 is output, the start interlock circuit relay is not energized, and the start interlock is canceled. In other words, fuel is injected and the engine is turned on by turning on the ignition switch 64 started.

The vehicle 31 sometimes moves itself and sometimes when it is loaded on a transporter, for example a semitrailer. Here the movement in the state loaded onto a semitrailer is assumed. It should be noted, however, that the following processing is equally applicable to a case in which the vehicle 31 moved independently.

An Indian 34 displayed website screen called "notification screen" will be in the server terminal 21 generated. This "notification screen" is set as the homepage of the website. Only the following important information is summarized on the "notification screen".

• a) Informationen bezüglich der Tatsache, dass der Motor des Fahrzeugs 31 außerhalb der regulären Stunden gestartet wurde.
• b) Informationen bezüglich der Tatsache, dass die Batteriespannung des Fahrzeugs 31 abgenommen hat.
• c) Informationen bezüglich der Tatsache, dass die Startverriegelung eingestellt oder freigegeben wurde.
• d) Informationen bezüglich der Tatsache, dass die Kommunikation zwischen dem Fahrzeug 31 und dem Serverterminal 21 unterbrochen wurde.
• e) Informationen bezüglich der Tatsache, dass eine Anforderung das Fahrzeug 31 noch nicht erreicht hat (beispielsweise Informationen bezüglich der Tatsache, dass eine Startverriegelung noch nicht in dem Fahrzeug 31 eingestellt wurde, obwohl ein Startverriegelungseinstellbefehl ausgegeben wurde).

Information about the fact that the vehicle 31 outside a predetermined range.

• a) Information regarding the fact that the engine of the vehicle 31 was started outside the regular hours.
• b) information regarding the fact that the battery voltage of the vehicle 31 has decreased.
• c) Information regarding the fact that the start interlock has been set or released.
• d) information regarding the fact that the communication between the vehicle 31 and the server terminal 21 was interrupted.
• e) information regarding the fact that a request is the vehicle 31 has not yet reached (for example, information regarding the fact that a start lock is not yet in the vehicle 31 has been set although a start lock setting command has been issued).

In other words, there is an automatic transmission from the side of the vehicle 31 , and when the automatically transmitted mobile body information from the server terminal 21 will be received in the server terminal 21 determined whether this mobile body information is displayed on the "notification screen" of the website to be shown.

When the engine of the vehicle 31 Be started outside the regular hours (17:00 to 8:00), will be information that says "engine of the vehicle 31 was started "automatically to the server terminal 21 transmitted via an electronic mail. This mobile body information corresponds to the aforementioned specific information b), and it is therefore determined that this information should be displayed on the "notification screen". The display content of the "notification screen" is updated in this way.

When the WWW browser through the terminal 11 which the vehicle 31 Web site data is managed by the server terminal 21 read via the WWW browser and on a screen of a display device of the terminal 11 displayed.

34 shows the homepage of the website, which is on the display device of the terminal 11 is displayed, or in other words: the screen that is displayed upon activation.

As in 34 4, the content "vehicle engine started off-hours" is displayed together with a content indicating the "time of occurrence" and "manufacturer,""modelnumber,""machinenumber," and "ID" of the vehicle 31 indicates. On the basis of the screen, the administrator can use the vehicle 31 learns that "the engine was started outside the regular hours" and he can take accurate and swift action against irregularities such as pranks.

The administrator can use the vehicle 31 via a remote control operation in the start-lock state. This is done by adjusting the screen of the terminal 11 to a "machine reactivation prohibition set screen" and by clicking the "disable motor reactivation" button. This will cause an electronic mail indicating that the vehicle 31 is to be brought into a start-lock state from the terminal 11 to the vehicle 31 transfer.

If data indicating that the vehicle 31 in the start-lock state in the communication terminal 56 of the vehicle 31 via the satellite communication antenna 58 are received, these data are in the communication control 54 loaded. In this way, a start lock setting command is given to the start latch circuit by the communication controller 54 output. As a result, the start interlock circuit relay is energized, and the start interlock state is set. In other words, no fuel is injected even if the ignition switch 64 is turned on, and the engine of the vehicle 31 can not be restarted.

On the side of the vehicle 31 it is determined whether the start lock has been set or not. If on the side of the vehicle 31 is determined that the start lock is set, information indicating that "the vehicle 31 remotely brought into the start-lock state "was sent by electronic mail automatically to the server terminal 21 transfer. This mobile body information corresponds to the aforementioned information d), which is why by the server terminal 21 it is determined that this information should be displayed on the "notification screen". The display content of the "notification screen" is updated in this way.

As in 34 shown, the content is set "lock remote control" on the screen of the terminal 11 displayed along with a content indicating the "time of occurrence" and "manufacturer", "model", "model number", "machine number" and "ID" of the vehicle 31 indicates. On the basis of the screen, the administrator can use the vehicle 31 learn that in the vehicle 31 "the start lock setting was performed remotely".

The transmission of the electronic mail, indicating that the vehicle 31 has been placed in a start-lock state, in the server terminal 21 saved. When the information indicating that "the start lock setting has been remotely performed" does not respond to the vehicle 31 by electronic mail after a predetermined period of time has elapsed after the transmission of the electronic mail to the vehicle 31 is transmitted in the server terminal 21 found that "a start lock in the vehicle 31 was not set even though a start lock command was issued. "In other words, it is determined that" a request is the vehicle 31 The reason for this may be either a malfunction or the like in the start-locking circuit of the vehicle 31 or a communication failure between the vehicle 31 and the server terminal 21 be. This mobile body information or communication state information corresponds to the specific information f), and is therefore transmitted through the server terminal 21 determined that this information should be displayed on the "notification screen". The display content of the "notification screen" is updated in this way.

As in 34 shown, the content becomes "No confirmation of lock received by vehicle" on the screen of the terminal 11 displayed along with a content indicating the "time of occurrence" and "manufacturer", "model", "model number", "machine number" and "ID" of the vehicle 31 indicates. On the basis of the screen, the administrator can use the vehicle 31 learn that "a confirmation of the lock has not been received" and he can take accurate and swift action against this irregularity.

The administrator can use the vehicle 31 release from the start lock state by a remote control operation. This is done by adjusting the screen of the terminal 11 Click on the "Motor reactivation enable screen" and click on the "Enable motor reactivation" button. This will cause an electronic mail indicating that the vehicle is in the start-lock state 31 should be lifted from the terminal 11 to the vehicle 31 transfer.

If data indicating that the vehicle 31 from the start lock state in the communication terminal 56 of the vehicle 31 via the satellite communication antenna 58 are received, these data are in the communication control 54 loaded. Thereby, a start lock release command to the start lock circuit from the communication controller becomes 54 output. As a result, the start interlock circuit relay is de-energized and the start interlock condition is canceled. In other words, fuel is injected when the ignition switch 64 is turned on, and the engine of the vehicle 31 can be restarted.

On the side of the vehicle 31 it is determined whether the start lock has been released. If on the side of the vehicle 31 is determined that the start lock has been released, information indicating that "the start lock of the vehicle 31 remotely controlled ", automatically via electronic mail to the server terminal 21 transmitted. This mobile body information corresponds to the aforementioned specific information d), which is why by the server terminal 21 is determined that this information should be displayed on the "notification screen". The display content of the "notification screen" is updated in this way.

The contents "Lock setting remotely canceled" will appear on the screen of the terminal 11 displayed along with a content indicating the "time of occurrence" and "manufacturer", "model", "model number", "machine number" and "ID" of the vehicle 31 indicates. On the basis of the screen, the administrator can use the vehicle 31 learn that for the vehicle 31 "the start interlock was removed remotely".

The transmission of the electronic mail, which indicates that the vehicle 31 has been released from a start-lock state is in the server terminal 21 saved. When information indicating that "the start-up lock has been remotely canceled" is not in response to electronic mail from the vehicle 31 after expiration of a predetermined period of time after the transmission of the electronic mail to the vehicle 31 is transmitted in the server terminal 21 found that "the launch lock in the vehicle 31 although a start-lock command has been issued. "In other words, it is determined that" a request is the vehicle 31 The reason for this may be either a malfunction or the like in the start-locking circuit of the vehicle 31 or a communication failure between the vehicle 31 and the server terminal 21 be. This mobile body information or communication state information corresponds to the specific information f), and is therefore transmitted through the server terminal 21 determined that this information should be displayed on the "notification screen". The display content of the "notification screen" is updated in this way.

The content "received no confirmation of the vehicle unlocking" is displayed on the screen of the terminal 11 displayed along with a content indicating the "time of occurrence" and "manufacturer", "model", "model number", "machine number" and "ID" of the vehicle 31 indicates. On the basis of the screen, the administrator can use the vehicle 31 learn that "a confirmation of the release of the lock has not been received" and he can take precise and swift action against this irregularity.

It should be noted that an automatic transmission from the side of the vehicle 31 can also be done when a starting device is actuated, although the vehicle 31 is in a start-up locked state. That is, information indicating that "the vehicle has been started although the start-up lock has been remotely set" may be displayed on the "notification screen" in FIG 34 are displayed.

It is assumed that the automatic transmission from the side of the vehicle 31 every day at 23:00. If the content of the daily work card as in 30 is updated, the updated work card is automatically from the vehicle 31 every day at 23:00. If from the side of the vehicle 31 over egg If no transmission has taken place for a predetermined period of time, for example 36 hours or more, this means that an irregularity in the communication status has occurred. Here, "36 hours" means one day (24 hours) plus the normal working time (12 hours: 8:00 to 20:00) of the next day.

The time ui the previous electronic mail from the vehicle 31 to the server terminal 21 is transmitted in the server terminal 21 saved. If over a predetermined period of time (36 hours) following the prior transmission of an electronic mail from the vehicle 31 No transfers are made in the server terminal 21 found that "no communication with the vehicle 31 is done for 36 hours or more. "In other words: it determines the communication between the vehicle 31 and the server terminal 21 is interrupted. This may be due to a problem on the part of the vehicle 31 For example, a failure or damage to the communication device in the vehicle 31 , or this is due to a disturbance of the communication status between the vehicle 31 and the server terminal 21 be conditional. This mobile body information or communication status information corresponds to the specific information e) and it is therefore stored in the server terminal 21 determined that this information should be displayed on the "notification screen". The display content of the "notification screen" is updated in this way.

The content "no communication with the vehicle for 36 hours or more" will appear on the screen of the terminal 11 displayed along with a content indicating the "time of occurrence" and "manufacturer", "model", "model number", "machine number" and "ID" of the vehicle 31 indicates how in 34 shown. On the basis of the screen, the administrator can use the vehicle 31 learn that "communication with the vehicle 31 "and he can take precise and swift action against this irregularity.

It should be noted that in this embodiment, an interruption of communication with the vehicle 31 is determined by the fact that, although a predetermined period has elapsed since the previous automatic transmission, the next automatic transmission has not yet been performed. However, an interruption of communication with the vehicle 31 be determined on the basis that, although a predetermined period of time since the previous request input by the terminal 11 . 12 .. and the vehicle 31 has elapsed, no response from the side of the vehicle 31 was transferred.

As previously mentioned, the voltage of the battery 63 of the vehicle 31 through the sensor group 62 recognized and in the communication control 54 entered. It is in communication control 54 Then it determines if the voltage in the battery 63 has been at or below a predetermined level (e.g., 23V) for a continuous period of time (eg, one minute or more). A decrease in the voltage of the battery 63 is a serious irregularity that not only indicates that starting the vehicle 31 difficult, but also that the communication function in the vehicle could fail. When the start locking circuit of the vehicle 31 is actuated, power is consumed by the start interlock circuit relay, therefore, a reduction in the voltage of the battery 63 can occur more easily.

If on the side of the vehicle 31 it is determined that the voltage of the battery 63 For a continuous period of time (for example, one minute or more) at or below a predetermined level (for example, 23 V), information indicating that "the voltage of the battery 63 in the vehicle 31 automatically "as an electronic mail to the server terminal 21 transfer. This mobile body information corresponds to the specific information c), therefore, a determination in the server terminal 21 is made that this information should be displayed on the "notification screen". The display content of the "notification screen" is updated in this way.

The content "battery voltage is low" is displayed on the screen of the terminal 11 displayed along with a content indicating the "time of occurrence" and "manufacturer", "model", "model number", "machine number" and "ID" of the vehicle 31 indicates how in 34 shown. On the basis of the screen, the administrator can use the vehicle 31 learn that "the voltage of the battery 63 "and he can take accurate and swift action against this irregularity.

As previously related to the 9 and 10 discussed, an automatic transmission takes place with changes in the position of the vehicle 31 ,

That means that, as in 10 shown, an automatic transmission takes place as soon as the vehicle 31 from the specific given range 129 differs. This specific predetermined range 129 can be considered the administrative district of the vehicle 31 (eg, "Tokyo") or the area in which the vehicle is located 31 may move (for example "within Japan"). Does the vehicle move? 31 out of this area, it can be stated that an Un regularity has occurred.

If on the part of the vehicle 31 it is determined that the vehicle 31 from the specific given range 129 information that indicates that the vehicle is "diverging 31 out of range ", automatically as an electronic mail to the server terminal 21 Transfer. This mobile body information corresponds to the specific information a), therefore a determination in the server terminal 21 is made that this information should be displayed on the "notification screen". The display content of the "notification screen" is updated in this way.

The content "vehicle is out of range" will appear on the screen of the terminal 11 displayed along with a content indicating the "time of occurrence" and "manufacturer", "model", "model number", "machine number" and "ID" of the vehicle 31 indicates how in 34 shown. On the basis of the screen, the administrator can use the vehicle 31 learn that "the vehicle 31 He can take precise and swift action against this irregularity.

It should be noted that the automatic transmission takes place as soon as the vehicle 31 from the specific given range 129 and information indicating that "the vehicle is out of range" is displayed on the "notification screen". However, an automatic transmission can also be done as soon as the vehicle 31 in the specific given area 129 penetrates so that information indicating that "the vehicle is within range" is displayed on the "notification screen". In this case, the specific default range is 129 given as an area in which the vehicle 31 normally does not penetrate.

Furthermore, the "notification screen" of the 34 similarly on a screen of another terminal, for example the terminal 12 instead of just at the terminal 11 are displayed. This will cause the "notification screen" of 34 also at the terminal 12 is displayed, and so important information generated up to the previous day can be easily obtained.

Displaying the "notification screen" of 34 can also only on the screen of the administrator-side terminal 11 be allowed to the vehicle 31 to manage, so that the display of the "notification screen" on the screen of other terminals, such as the terminal 12 , is prohibited. This is realized, for example, by entering a specific ID number or a specific code number (one the terminal 11 corresponding number) as a condition for the display of the "notification screen" of 34 is given.

In this embodiment, those on the "notification screen" of 34 information to be displayed is not limited to the information described under a) to f).

For example, information about that can change the rental period of the vehicle 31 to the end of a customer on the "notification screen" are displayed. The proximity of the end of the rental time may be determined by the operating hour meter value in the vehicle 31 be detected, or it may be through an inside the communication terminal 56 provided clock can be detected.

An automatic transmission by the vehicle 31 can also be done when the vehicle 31 travels a predetermined distance or more so that information indicating that "a predetermined distance or more has been traveled" is displayed on the "notification screen". This predetermined distance is set, for example, as a distance considered to be longer than that of the vehicle 31 normally covered route.

An automatic transmission from the side of the vehicle 31 can also be done if an error code in the communication terminal 56 of the vehicle 31 is entered so that information indicating the occurrence of an error is displayed on the "notification screen". It should be noted that the content of the error codes displayed on the "notification screen" may be limited only to specific irregularity items (serious irregularity items). Furthermore, the display elements of the "notification screen" of 34 for every vehicle 31 . 32 ... distinguish. For example, for the vehicle 31 only the display element a) and for the vehicle 32 only the display element b) are displayed on the "notification screen".

In this embodiment, the "notification screen" becomes the terminal 11 displayed, which is fixed in one position. However, the contents of the "notification screen" may be displayed on a portable terminal.

For example, the contents of the "notification screen" may be on a portable telephone shown in which a WWW browser is installed.

In this case, a packet communication network and the Internet 2 of the portable telephone connected via a gateway. Switching between the packet communication network protocol and the TCP / IP protocol of the Internet 2 is done through the gateway, so that the content of the site of the Internet 2 is displayed on a screen of the portable phone. Once the "notification screen" through the server terminal 21 is updated, an audio message is generated in the portable telephone indicating that "new information has been received". As a result, the content of the updated "notification screen" is displayed on the screen of the portable telephone. It should be noted that only specific display elements of a) to f) are set as the display elements of the "notification screen" displayed on the portable telephone. For example, only the information b) that "the engine of the vehicle 31 It can be displayed on the screen of the portable phone, which means that it is possible to display urgent information about a vehicle 31 be read in real time from the screen of the portable phone, even if the administrator at one of the terminal 11 located at a remote location.

Construction are expensive and are therefore often rented. One as a group rental known system is used for rental of construction machinery. This is a system where, due to the different existing types of construction machinery (small hydraulic excavators, medium Hydraulic excavator, big Hydraulic excavators, and the like) a wide variety of construction machinery types shared by several sales offices is being used. If a rental request for a specific model is directed by a customer to a sales office, however requested construction machine model is out of stock, this specific Construction model can be supplied by another sales office, so that no business opportunity escapes.

Around To respond to a customer request, the management of inbound must and outgoing construction equipment can be reliably performed in any sales office. The following is an embodiment for the management of inputs and outputs described.

35 shows a structural example of this embodiment. 35 shows each sales office 130 . 131 . 132 in an area known for example as "Tokyo" 135 exist. The sales office 130 is located in "West Tokyo", the sales office 131 is located in "North Tokyo", and the sales office 132 is located in "South Tokyo". 133 and 134 indicate the jobs of customers. The vehicles 31 . 32 be in the sales office 130 to 132 managed. It should be noted that in reality a larger number of sales offices, jobs and vehicles (mobile machines) is given, which have been omitted for clarity.

From the sales offices 130 . 131 . 132 is 131 chosen as the main office and 130 . 132 are set up as branches. The main office 131 manages the vehicles 31 . 32 in the whole. The main office 131 has a terminal 11 on. An identical terminal 11 can in the branches 130 . 132 be provided.

The position of the sales offices 130 . 131 . 132 are given as p (Px, PY), Q (Qx, QY) and R (Rx, RY) in an XY coordinate system. The respective positions of the jobs 133 . 134 are indicated by Z (Zx, ZY) and W (Wx, WY) in an XY coordinate system. It should be noted that the position may be given as terrestrial latitude and longitude to conform to a GPS map.

Entry and exit areas centered on points P, Q and R are for each of the sales offices 130 . 131 . 132 specified. For example, an entrance area 130a centered on point P for the branch office 130 specified. An exit area 130b is also set centered on the point P. The exit area 130b is larger than the entrance area 130a , and there is a hysteresis ΔV between the boundary line of the exit region 130b and the boundary line of the entrance area 130a ,

Similarly, an entrance area 131 and an exit area 131b , which are centered on the point Q, for the main office 131 ^II predetermined, and an entry area 132a and an exit area 132b that are centered on the point R is for the branch office 132 set up. The size of the entrance and exit areas is determined taking into account the margin of error of the GPS meter, the size of the sales office, and so forth. For example, the entrance and exit areas are determined to be several hundred meters long and several hundred meters wide.

working area 133 . 134 , which are centered on the points Z and W respectively, are for the jobs 133 . 134 set.

Position information about the entry and exit areas of sales offices 130 . 131 . 132 and position information regarding the Ar areas of employment 133 . 134 are in the communication control 54 of the vehicle 31 saved. The same position information will be similar in communication control 54 of the vehicle 32 saved.

A communication connection between the server terminal 21 and the communication terminals 56 of the vehicles 31 . 32 is confirmed in this way. At the same time, position information regarding each sales office 130 . 131 . 132 and position information regarding jobs 133 . 134 from the server terminal 21 to the vehicles 31 . 32 transfer. As a result, position information about the entry and exit areas of the sales offices 130 . 131 . 132 and position information about workspaces 133 . 134 in the communication controls 54 of the vehicles 31 . 32 saved. When the communication connection is confirmed, a message indicating that one of the vehicles 31 . 32 incoming communication application, on the screen of the terminal 11 displayed. Communication with the vehicles 31 . 32 is possible as soon as the application reception in the terminal 11 is confirmed.

Using the vehicle 31 As a representative example, the following is the procedure when leaving a vehicle 31 described.

As before with the help of 9 and 10 described, the position of the vehicle 31 via the GPS antenna 59 through the GPS sensor 57 recognized. The recognition result of the GPS sensor 56 gets into a communication control 54 entered. The recognized position of the vehicle 31 and the positions of the entry and exit areas of each of the sales offices 130 . 131 . 132 be in the communication control 54 compared to each other, and it is determined whether the vehicle has been introduced into the entry and exit area or moved out.

There is provided a case where, for example, the vehicle 31 to the branch 130 is brought.

The vehicle 31 moves from outside the entrance area 130a the branch office 130 into it, and it will depend on the vehicle 31 for a predetermined period of time (for example, 2 or 3 minutes) in the entrance area 130a stays, determines if the vehicle 31 to the branch 130 was brought. The state of remaining in the inlet area 130a for a predetermined period or more is evaluated in the context of a case where the vehicle 31 simply through the territory of the branch 130 moves. If as a result it is determined that the vehicle 31 in the entrance area 130a is entered, an identification code of the vehicle 31 indicates ("vehicle 31 "), an identification code of the branch office 130 indicates ("West Tokyo Branch") and an identification code indicating the "entry" (collectively referred to as "entry information" hereinafter) at this time as transmission data from the communication controller 54 to the communication terminal 56 transfer. An electronic mail containing this entry information is then automatically transmitted by the communication terminal 56 via the satellite communication antenna 58 to the server terminal 21 transfer. It is assumed here that the server terminal 21 at the location of the manufacturer of the vehicles 31 . 32 located.

An Indian 36 The website screen, hereinafter referred to as the "entry and exit screen", is then displayed in the server terminal 21 generated.

More specifically, an automatic transmission takes place from the side of the vehicle 31 , and when the automatically transmitted entry information in the server terminal 21 will be received, this entry information in the "entry and exit screen" of the website in the server terminal 21 whereupon the display content of the "entry and exit screen" is updated.

If the WWW browser in the terminal 11 which the vehicle 31 managed, the site data is from the server terminal 21 read via the WWW browser, and the "entry and exit screen" is displayed on a screen of the display device of the terminal 11 displayed.

36 shows the website screen that is on the screen of the terminal 11 is shown. 36 represents the "entrance and exit screen", which shows the time course of entry and exit of the vehicle 31 shows.

As in 36 is presented, a content that indicates that the vehicle has "entered the area of the West Tokyo branch", displayed in real time together with the "entry time". From this screen, the administrator can recognize that the vehicle 31 "entered the territory of the West Tokyo Branch" and can thus make reliable plans for a client.

If it is found in a similar way that the vehicle 31 from the exit area 130b the branch office 130 out and for a predetermined period of time (for example 2 or 3 minutes) outside the exit area 130b remained, it is found that the vehicle 31 the branch office 130 has left. At the time of this finding will be information indicating that the vehicle 31 the branch "West-Tokyo" 130 has left (hereinafter referred to as "exit information") automatically by electronic mail to the server terminal 21 transfer. As in 36 shown, is a content indicating that the vehicle 31 "has left the West Tokyo branch", in real time along with the "exit time" on the "entry and exit screen" on the display of the terminal 11 displayed.

If similarly determined that the vehicle 31 in the entrance area 132a the branch office 132 occurred at this time, entry information indicating that the vehicle 31 in the area of the branch "South Tokyo" 132 occurred by an electronic mail automatically to the server terminal 21 transmitted. As in 36 shown, the content is that the vehicle 31 "entered the area of the South Tokyo office" in real time together with the "save time" on the "entry and exit screen" on the display device of the terminal 11 displayed.

If it is determined that the vehicle 31 the exit area 132b the branch office 132 At this point in time, entry information ^III , indicating that the vehicle is leaving the airport, will be left 31 the branch office "South-Tokyo" 132 has left automatically to the server terminal 21 transfer. Like in the 36 shown, is the content that indicates that the vehicle 31 "has left the branch South-Tokyo", in real time together with the "exit time" on the "entrance and exit screen" of the display device of the terminal 11 displayed.

If the vehicle 31 in the entrance area 131 the main office "North Tokyo" 131 enters or if the vehicle 31 the exit area 131b the main office "North Tokyo" 131 leaves, is a content indicating that the vehicle 31 "entered the North-Tokyo main office" or "left the North-Tokyo main office", on the display device of the terminal 11 displayed on the "entrance and exit screen".

Thus, the latest entry and exit history of the vehicle 31 shown in real time as in 36 shown. The "entry and exit screen" for the vehicle 32 is done in a similar way as for the vehicle 31 so that the latest entry and exit history of the vehicle 32 * is displayed in real time. In this way, the entry and exit management for the vehicles 31 . 32 reliably and without mistakes, and as a result no business opportunities escapes and sales profits increase dramatically.

If it is determined that the vehicle 31 in the workspace 133 the hiring customer has occurred at this time, transfer information indicating that the vehicle 31 to the job 133 has been spent automatically to the server terminal 21 transmitted by electronic mail. Thus, the content that indicates the vehicle 31 "to the job 133 "in real time on the display device of the terminal 11 together with the "transfer time".

If it is determined that the vehicle 31 the workspace 133 At this point, distance information will be given to the vehicle 31 from the job 133 was removed by electronic mail automatically to the server terminal 21 transfer. Thus, the content that indicates the vehicle 31 "from the job 133 was removed "in real time on the display device of the terminal 11 displayed together with the "removal time".

Similarly, when the vehicle 31 in the workspace 134 enter or leave a content on the display device of the terminal 11 displayed, indicating that the vehicle 31 "to the job 134 was spent "or" from the job 134 was removed. "The transfer and distance history of the vehicle 31 will be updated this way.

The course of movement of the vehicle 31 after leaving the sales offices 130 to 132 can also be at the terminal 11 are displayed. This is achieved by the vehicle 31 For example, it automatically causes every 10 to kilometers traveled automatically transfer position data. In this way, the movement history and the current position of the vehicle 31 at the terminal 11 be read.

By comparing the current position of the vehicle 31 and the known positions Z. W of the jobs 133 . 134 can on the screen of the terminal 11 be determined if the vehicle 31 within the jobs 133 . 134 located.

If the managed vehicle 31 the administrative district ("Tokyo") 135 can leave information that indicate that the vehicle 31 automatically "towering over the administrative district" and on the "notification screen" of the 34 are displayed. This allows the administrator to find out that the vehicle 31 "outside the administrative district" and he can take swift and accurate action against this irregularity.

The display of the "Entry and Exit Screen" in 36 can only on the screen of the administrator-side terminal 11 be allowed, which the vehicles 31 . 32 managed, making the "entrance and exit screen" not on the screen of another terminal than the terminal 11 is shown. This is realized, for example, by entering a specific ID number or a specific code number (one the terminal 11 corresponding number) as a condition for the display of the "entry and exit screen" of 36 is given.

The transfer of construction machinery 31 . 32 to the tenant or picking up the construction machinery 31 . 32 by the tenant by loading the construction machinery 31 . 32 on the semitrailer 35 , The cost of transport by a semi-trailer 35 are high, which is why it is necessary to increase the efficiency of transportation by the semitrailer 35 increase and reduce transport costs. It is also necessary to increase rental opportunities and thus increase the sales profits by increasing the transfer speed to the renter or the speed of collection by the renter, so as to improve the efficiency of transport by semi-trailer 35 to increase.

An embodiment according to which the transport efficiency of the construction machines 31 . 32 can be increased, referring to below 37 described.

As in 36 Be described, information about whether the vehicles 31 . 32 in the areas of outlets 130 to 132 occurred or left, and information about whether the vehicles 31 . 32 to the jobs 133 . 134 spent or picked up from there, on the side of the terminal 11 managed.

It is assumed here that entry and exit information and entry and removal information indicating that "the vehicle 31 in the area of the branch 130 occurred and the vehicle 32 to the job 134 was spent ", at the terminal 11 were obtained as in the 37 (a) shown. At this time, a request is issued stating that "the vehicle 31 to the job 133 spent and the vehicle 32 from the job 134 On the basis of this entry and exit information and the transfer and removal information can then be sent by electronic mail from the terminal 11 to the semitrailer 35 Work order data are transmitted, which indicate that "the vehicle 31 in the branch office 130 to the job 133 to be spent and on the way back the vehicle 32 from the job 134 picked up and to the point of view 130 In this case, as previously described in connection with the 4 described, "the current position of the semi-trailer 35 , the current position of the vehicle 31 (Position of the branch office 130 ), the position of the job 133 , the current position of the vehicle 32 (Position of the job 134 ) and a work order message "on a screen in the semi-trailer 35 built-in terminals 14 displayed. The operator of the semi-trailer 35 can then follow the procedures according to the screen of the terminal 14 perform efficiently.

Therefore, the semi-trailer moves 35 to the branch 130 , loads the vehicle 31 and leaves with the vehicle 31 the branch office 130 , At this time, exit information will indicate that the vehicle 31 the branch office 130 has left automatically from the vehicle 31 out and the contents of the "Entry and Exit Screen" in 36 will be updated. The one with the vehicle 31 loaded semitrailers 35 then drives over a street 136 and enters the job 133 one. At this time, transfer information will indicate that the vehicle 31 in the workplace 133 occurred from the vehicle 31 transferred automatically, and its transfer and removal history is updated.

The empty semi-trailer 35 then drives on a street 137 and enters the job 134 one. The semi-trailer 35 loads the vehicle 32 up and away the vehicle 32 from the job 134 , At this time point, distance information mations that indicate that the vehicle 32 from the job 134 was removed from the vehicle 32 transferred automatically, and its transfer and removal history is updated.

The one with the vehicle 32 loaded semitrailers 35 then drives on a street 138 and enters the area of the branch office 130 one. At this time, entry information will indicate that the vehicle 32 in the area of the branch 130 occurred from the vehicle 32 automatically transmitted, and the entry and exit of the vehicle 32 will be updated.

Thus, the semitrailer is 35 able to transfer the vehicle 31 and the pick-up and return of the vehicle 32 in one go. As a result, the period during which the semitrailer 35 is empty, thereby increasing transport efficiency.

37 (b) shows another example of a transport process.

It is assumed here that entry and exit information and entry and removal information indicating that "the vehicle 31 to the job 133 was transferred and the vehicle 32 to the job 134 was spent (vehicles 31 . 32 have the range of branches 130 . 132 leave) ", at the terminal 11 were obtained as in the 37 (b) shown. At this time, a request is issued stating that "the vehicle 31 to the job 134 spent and the vehicle 32 from the job 134 On the basis of this entry and exit information and the transfer and removal information can then be sent by electronic mail from the terminal 11 to the semitrailer 35 Work order data are transmitted, indicating that "at the workplace 133 located vehicle 31 to the job 134 spent and the vehicle 32 from the job 134 away and to the branch office 132 In this case, as previously described in connection with the 4 described, "the current position of the semi-trailer 35 , the current position of the vehicle 31 (Position of the job 133 ), the current position of the vehicle 32 (Position of the job 134 ), the position of the branch 132 and a work order message "on a screen in the semi-trailer 35 built-in terminals 14 displayed. The operator of the semi-trailer 35 can then follow the procedures according to the screen of the terminal 14 perform efficiently.

The semi-trailer 35 thus moves to the job 133 in the street 139 , loads the vehicle 31 up and away the vehicle 31 from the job 133 , At this time, distance information will indicate that the vehicle 31 from the job 133 was removed from the vehicle 31 transferred automatically, and its transfer and removal history is updated. The one with the vehicle 31 loaded semitrailers 35 then drives on the street 140 and enters the job 134 one. At this time, transfer information will indicate that the vehicle 31 in the workplace 134 occurred from the vehicle 31 automatically transferred, and the transfer and removal history of the same is updated.

The semi-trailer 35 then loads the vehicle 32 up and away the vehicle 32 from the job 134 , At this time, distance information will indicate that the vehicle 32 from the job 134 was removed from the vehicle 32 automatically transferred and its transfer and distance history is updated.

The one with the vehicle 32 loaded semitrailers 35 then drives on the street 141 and enters the branch office 132 one. At this time, entry information will indicate that the vehicle 32 to the branch 132 occurred from the vehicle 32 automatically transmitted, and the entry and exit of the vehicle 32 will be updated.

Thus, the semitrailer is 35 able to transfer the vehicle 31 and the pick-up and return of the vehicle 32 in one go. As a result, the period during which the semitrailer 35 is empty, thereby increasing transport efficiency.

It should be noted that in 37 it is determined if the vehicles 31 . 32 within the jobs 133 . 134 located by the positions of the vehicles 31 . 32 and the jobs 133 . 134 that are of a fixed size. However, it can also be determined if the vehicles 31 . 32 within the jobs 133 . 134 located by the current position of the vehicle 31 and the middle positions Z, W of the jobs 133 . 134 be compared.

In the aforementioned embodiment, the vehicle 31 remotely controlled to a start-lock state (hereinafter referred to as "start-up lock") and the vehicle 31 is remote-controlled in a start-up lock release state (hereinafter referred to as "start-up release"). The construction machine 31 works during a certain time window (17:00 to 8:00, except usually the regular hours) usually not. If the engine of the construction machine 31 In this time window begins to work, the occurrence of an irregularity, such as a prank, can be assumed. However, it is tiring every day at the same time from the terminal 11 remotely perform the start lock and the start unlocking.

In the following, an embodiment will be described in which data for a specific time window in advance from a terminal 11 to the vehicle 31 be transferred, so that the vehicle 31 at the beginning of this specific time window is placed in the start-lock state and the vehicle 31 is put into the start unlock state at the end of the specific time window.

38 Fig. 10 is a flow chart showing the processing sequence of this embodiment.

Initially, the screen of the terminal switched to the "Motor reactivation prohibition setting screen" appears 11 by clicking the "Time Window Specification" button, a display requesting the determination of a "lock start time Ts". In response, for example, "17:00" is indicated as the content of the "lock start time Ts". Thus, the lock start time Ts of the vehicle 31 set to "17:00" (step 701 ).

Subsequently, a display appears requesting the indication of a "lock end time Te". In response, for example, "8:00" is input as the content of "lock end time Te". Thus, the lock end time Te of the vehicle 31 set to "8:00" (step 702 ).

The setting data for the lock start time Ts and the lock end time Te are then output from the terminal 11 to the vehicle 31 as electronic mail (step 703 ).

When the data Ts, Te from the communication terminal 56 of the vehicle 31 via the satellite communication antenna 58 are transmitted, this data is stored in a memory in the communication terminal 56 entered (step 704 ). Inside the communication terminal 56 of the vehicle 31 a clock and a timer are provided. The current time Tn is obtained from the inner calendar and the timer (step 705 ). The present time Tn is then compared with the lock start time Ts and the lock end time Te (steps 706 . 707 ).

If the current time Tn is later than the lock start time Ts (17:00) and earlier than the lock end time Te (8:00) (Yes in the steps 706 . 707 ), a start lock setting command from the communication terminal 56 to the start latch circuit via the communication controller 54 output. As a result, the Startverriegelungsschaltungsre relay is energized, whereby the vehicle enters a start-lock state. In other words, no fuel is injected even if the ignition switch 64 is turned on, and the engine of the vehicle 31 can not be restarted (step 708 ).

If the current time Tn is the lock start time Ts (17:00) or earlier or the lock end time Te (8:00) or later (NO in the steps 706 and 707 ), a start unlock command from the communication terminal 56 via the communication control 54 output to the start latch circuit. As a result, the start-up lock relay is de-energized, causing the vehicle to enter a start-unlock condition. In other words, fuel is injected when the ignition switch 64 is turned on, and the engine of the vehicle 31 can be restarted (step 709 ).

In this way, the vehicle enters 31 automatically enters a start lock state every day during a certain time window (17:00 to 8:00), and enters a start unlock state at the end of the specific time window.

In 38 becomes the vehicle 31 However, the vehicle may be put into the start-lock state every day 31 also be put into the start-lock state only on certain days. In this case, in the steps 701 . 702 certain days of the week (such as Saturday and Sunday) are set at which the starting of the vehicle 31 Is blocked.

The construction machine 31 does not work during certain times of the year (for example, in the New Year period) and it is therefore necessary to use the vehicle 31 during these times to the start locked state to prevent pranks and the like. When renting the construction machine 31 at the end of the rental period are also put into the start locking state, so that a non-conforming use after the rental period can be prevented.

39 FIG. 10 is a flowchart illustrating a processing sequence according to an embodiment in which the startup is locked after a rental period has elapsed.

First, a customer (user) transmits a request for a network duration (for example, March 3, 8:00 to March 15, 20:00) to the terminal 11 . which the vehicle 31 managed (step 801 ). The vehicle 31 is then delivered to the customer (step 802 ). It should be noted that the request and the delivery procedures after the steps 801 . 802 via communication over the internet 2 can be done.

When the "usage duration" button is clicked, with the screen of the administrator-side terminal 11 is switched to the "motor reactivation prohibition setting screen", a display requesting the indication of "use start date and time Ds" appears. In response, for example, "3 March, 8:00" is input as the content of "Usage start date and time Ds". Thus, the date and time of commencement of use are Ds of the vehicle 31 set to "March 3, 8:00" (step 803 ).

Subsequently, a display appears requesting the determination of the "use end date and time De". In response, for example, "March 15, 20:00" is inputted as the content of "use end date and time De". Thus, the date and time of the end of use are De of the vehicle 31 set to "March 15, 20:00" (step 804 ).

The setting data for the date and time of commencement of use Ds and the date and time of the end of use De are then provided by the terminal 11 to the vehicle 31 as electronic mail (step 805 ).

When the data Ds, De from the communication terminal 56 of the vehicle 31 via the satellite communication antenna 58 who receive the, this data in a memory in the communication terminal 56 entered (step 806 ). Inside the communication terminal 56 of the vehicle 31 a clock and a timer are provided. The current time Dn is obtained from the inner calendar and the timer (step 807 ). The present time Dn is then compared with the date and time of commencement of use Ds and the date and time of the end of use De (steps 808 . 809 ).

If the current time Dn is later than the date and time of commencement of use (March 3, 8:00) and earlier than the date and time of the end of use De (March 15, 20:00) (YES in the steps 808 . 809 ), a start unlock command from the communication terminal 56 via the communication control 54 transmitted to the start interlock circuit. As a result, the start interlock circuit relay is no longer energized, thereby transitioning to the start unlock state. In other words, fuel is injected when the ignition switch 64 is turned on, and the engine of the vehicle 31 can be restarted (step 810 ).

If the current time Dn is the date and time of commencement of use Ds (March 3, 8:00) or earlier, or the date and time of the end of use De (March 15, 20:00) or later is (NO in the steps 808 and 809 ), is from the communication terminal 56 a start lock setting command via the communication controller 54 output to the start latch circuit. As a result, the start interlock circuit relay is energized, thereby transitioning to the start interlock state. In other words, no fuel is injected even if the ignition switch 64 is turned on, leaving the engine of the vehicle 31 not restarted (step 811 ). As a result, use contrary to the contract is prevented after the end of the rental period (Ds to De (since the engine of the vehicle 31 can not start, the vehicle can 31 be picked up at any time following the end of the rental period (Ds to De) (step 812 ).

In order to set a start-up lock state during New Year time and set a start unlock state at the end of the New Year time, as in 39 Shown is the New Year time (Ds to De) in the steps 803 . 804 adjusted, the contents of the step 810 on "start interlock" and the content of the step 811 is set to "Start unlock". Thus, a start-up lock state during the New Year time (Ds to De) (step 810 ) and a start unlock state are set for the rest of the year (step 811 ).

It should be noted that in the 38 and 39 Data from the terminal 11 to a single vehicle 31 be transferred, so that the vehicle 31 is automatically set to the start lock state. However, data may be from the terminal 11 to several vehicles (for example the vehicles 31 . 32 ) are transmitted simultaneously so that the plurality of vehicles are automatically placed in a start-up lock state.

By combining the embodiment of 39 and the embodiment of 37 If a use contrary to contract can be prevented after expiry of a rental period, the collection after expiry of the rental period can be carried out efficiently. If you take the case 37 (a) as an example, the customer leaves at the end of the rental period of the vehicle 32 the vehicle 32 unattended at the workplace 134 , Although the vehicle was 32 unattended at the workplace 134 left behind, however, at the end of the rental period (Ds to De) the start is locked and the vehicle 32 can therefore not be used by the customer contrary to the contract. When the time comes, the vehicle 31 to the other job 133 The semi-trailer can bring 35 the vehicle 31 to the job 133 bring and at the same time at the workplace 134 left vehicle 32 remove and take away. Thus, the pickup of the vehicle takes place 32 after expiry of the rental period of the same efficient.

In this embodiment, as the vehicle 31 mainly a construction machine provided. If the engine of a construction machine can not be restarted, it is not possible to operate the rotating bodies and tools. Thus, the risk of improper operation of the tools and the rotating structures can be avoided by locking the start. In other words, this embodiment can be applied not only for preventing improper operation following a rental period but also for security measures for preventing errors. For example, when the operating lever of a tool of the construction machine 31 erroneously operated by an inexperienced in these procedures operator (for example, a primary school student), there is a risk of improper operation of the tool. In this embodiment, incorrect operations such as improperly operating a tool can be prevented by locking the start of the construction machine.

For the owner a company involved in construction is by doing construction projects and by construction workers can operate, are the labor administration of the workers and the work plan administration important. The workers have to therefore daily Create work reports. Usually is the daily creation Work reports accompanied by reading and entering the operating hours counter Work awkward and represents a significant burden on the worker. As the input are done manually, are also due to input errors and the like inaccurate daily Work reports generated.

Further contain daily Work reports include information that is not only important for construction companies who are the users of construction machinery, but also for construction machinery renting rental companies, used machinery dealers, used construction machinery sell and manufacturers that make construction machinery. Especially There can be a difference between a rental company and a customer who owns the construction machinery and those who do not do so by talking about the History of the work reports on it experienced, and therefore are the daily ones Workable useful in the customer administration. A used machine dealer, the sold used construction machinery, the past useful life, calculate the work efficiency and the like of a construction machine, by the course of the daily Reports on work, and thus the daily work reports at the Fixing the price of a used vehicle will be useful. A manufacturer of construction machinery can increase the durability of a construction machine calculate by taking the course of daily work reports in Brings experience, and thus the daily work reports are included development and the like of future models.

It is therefore required daily Real-time work report information from each of the terminals to be able to get.

in the The following will therefore be an embodiment described in the daily Work reports are created accurately and without load on a worker can, and at the daily Work report information from a terminal easy in real time can be obtained.

The server terminal 21 is provided in a manufacturer's office and a "daily work report screen" website screen as in 40 shown is generated.

As described above, when the specific time reaches 24: L00 can be reached in the 30 displayed operating card data up to a specified time (for example, 20:00) that day from the vehicle 31 automatically transmitted and to the terminal 11 of the administrator via the server terminal 21 be transmitted automatically.

The Operating card data can however further processed and displayed as a daily work report become.

Every day at 24:00 the working card, the date and the working hours ( 40 ) by 24:00 that day automatically from the vehicle 31 transfer. Here is the working map a table in which the output of the vehicle 31 operating hours counter (whether the engine is working or not) and the output of the vehicle 31 provided calendar and the timer at any time compared to indicate the periods in which the engine is running. In the 40 black shaded periods correspond to the periods in which the engine of the vehicle 31 is working. The operating time is the cumulative value of the operating hours counter for one day (the daily operating time of the engine).

If from the vehicle 31 an automatic transmission takes place and the automatically transmitted mobile body information which "work In the server terminal, specify "card", "date" and "operating time" 21 are received, this mobile body information becomes in the server terminal 21 used to perform processing for updating the "Daily Work Report Screen" site page.

If then the WWW browser in the terminal 11 is activated, the site page data becomes the server terminal 21 read via the WWW browser, and the "daily work report screen" is displayed on the screen of the display device of the terminal 11 displayed.

The "date", the "work card" and the "operating time", which govern the operation of the vehicle 31 are then updated to the latest data and as in 40 shown. It should be noted that the following information is also displayed on the "Daily Job Report Screen": "Name of the Customer" who owns the vehicle 31 uses (ABC Doboku (KK)), "name of the job" on which the vehicle 31 works (Iroha Quarry), "Names of Servers" every day, and "Remarks" regarding maintenance and the like. The entries for "Customer Name", "Workplace Name", "Operator Name" and "Remarks" can be obtained by communication over the Internet 2 be performed. When inputs have been made to "customer's name", "job name", "operator's name", and "remarks" at the customer's terminal, the inputted data will be sent to the server terminal 21 over the internet 2 and the contents of the "daily work report screen" are updated according to the entered data.

In this way, the latest daily work report will be displayed in real time on the screen of the terminal 11 is displayed and can thus easily from the screen of the terminal 11 be read. In other words, daily work reports can be accurately created without burdening the operator. As a result, a construction company can perform accurate employment management and accurate daily work report management.

If the terminal 11 is provided in a rental company, the course of the daily work report on a screen of the terminal 11 which allows strong customers to be distinguished from less-active customers. This information can be used in customer management. For example, heavy users may receive a warning or it may be decided to deny such customers leases. By learning the history of daily work reports, customers can find the vehicle 31 barely use, be found out, and these customers can be advised the vehicle 31 return. By recording the course of the daily work reports, there may also be a time for the maintenance of the vehicle 31 be planned in advance.

When the terminal 11 Located in the office of a used equipment dealer selling used construction equipment, the history of daily work reports can be viewed from a screen of the terminal 11 can be read, and the past useful life, the operating efficiency and the like of the construction machines can be calculated. As a result, a suitable used vehicle price for the used vehicles can be set.

If the terminal 11 Provided in the office of a manufacturer of construction machinery, the course of daily work reports can be viewed from a screen of the terminal 11 be learned, whereby the durability of the construction machine can be calculated. This may be used in the development and the like of future models.

As in 41 can also be a curve of the course of the operating hours counter on a screen of the terminal 11 are displayed. The abscissa of the curve in 41 indicates the time, and the ordinate is the cumulative value of the engine operating time, which is measured by the operating hours counter. From the curve in 41 Time points for maintenance, for example routine inspections, can be planned ahead.

The display of 40 and 41 can only on the screen of the terminal 11 be allowed, which is the vehicle 31 managed, causing the 40 and 41 not on the screen of another terminal than the terminal 11 is shown. This is done, for example, by entering a particular ID code number or specific code number (one of the terminals 11 corresponding number) to the condition for the display of 40 and 41 is done.

Although no particular problem arises when only one vehicle 31 automatically transmits data at a certain time, however, the communication lines can be overloaded when the multiple vehicles 31 . 32 . 33 ... automatically transmit all at the same time at the specific time 24:00, which may lead to possible disabilities such as communication delays.

It is therefore possible to have different time data for the automatic transmission in each of the plurality of vehicles 31 . 32 . 33 ... to adjust. However, this software must be different includes automatic transmission time data to be installed individually in each vehicle. As a result, parts can not be standardized among the multiple vehicles and the overall system cost increases.

It It is therefore necessary to set the automatic transmission times among the several vehicles while varying the standardizability the software to be installed in each of the several vehicles is maintained. embodiments a method for realizing the object of the invention described below.

First embodiment

In the several vehicles 31 . 32 . 33 ... is recognized that a communication terminal 56 (please refer 21 ) was installed in each vehicle, or in other words: that energy from an energy source 63 to the communication terminal 56 was created. The duration of the power supply is then measured by means of a calendar and a timer inside the vehicle. An individual automatic transmission time is then set in each vehicle, with the energy supply time of this vehicle serving as a reference.

When the power supply time of the vehicle 31 is assumed to be 9:32, a fixed period of twelve hours after the power supply time is 9:32 (21:32) as the vehicle's automatic transmission time 31 set. When the power supply time of another vehicle 32 with 10:30 is assumed, the automatic transmission time of the vehicle 32 is set to 22:30, and thus the automatic transmission times among the plurality of vehicles can be varied.

Second embodiment

In the vehicles 31 . 32 . 33 ... it is recognized that a motor key switch 64 (please refer 21 ) was turned on in each of the vehicles from one to. The timing of turning off the key switch is measured by the calendar and the timer inside the vehicle. The last key switch off time, or in other words: the time when the engine key switch 64 is turned off for the last time during a calendar day (0:00 to 24:00) is then saved as data. An individual automatic transmission time for each vehicle is then set with this last key switch off time as a reference.

More precisely, when the time when the engine key switch 64 of the vehicle 31 last shut down at 15:47, a fixed period of fifteen hours after the last key switch off time becomes 15:47 (6:47) as the automatic transmission time of the vehicle 31 set. When the time of last turning off the key switch of another vehicle 32 is assumed to be 15:55, the automatic transmission time of this vehicle 32 for example, set to 6:55, and thus the automatic transmission times among the plurality of vehicles can be varied.

Instead of detecting the on / off state of the engine key switch 64 , the state of the engine operation (for example, the voltage value of the alternator) can be directly recognized. This allows the automatic transmission time to be set as the reference at the time the motor has stopped operating.

An automatic transmission time can also coincide with the time when the engine key switch 64 is switched on, or the time at which the motor starts to operate, be set as a reference.

Third embodiment

In the several vehicles 31 . 32 . 33 ... software for the automatic generation of random numbers is installed. When the random number generation software is activated, a random number is generated, and the individual automatic transmission time of each vehicle is set with the generated random number as a reference.

Specifically, if the range of random number generation is set to be "00" to "59" and that in the vehicle 31 generated random number "38" becomes a time (24:38) in which the generated time "38" is the "minute unit" and a fixed numerical value "24" is the "hour unit", as the automatic transmission time of the vehicle 31 set. Suppose that in another vehicle 32 generated random number is "55", so is the automatic transmission time for the vehicle 32 24:55, and thus the automatic transmission times among the several vehicles can be varied. The range of random number generation can also be set as a four-digit numerical value within the frame from "24:00 (0:00) to 1:00" so that the numerical value of the generated random number is set as the automatic transmission time. Automatic transmission times can also be determined by arranging the generated random number according to a fixed law.

Fourth embodiment

When the automatic transmission times among the several vehicles 31 . 32 . 33 ... are varied, the range of variation can be restricted to a range near a fixed time.

Under From a management point of view, it is desirable to have "work card data" from each vehicle while Automatically transfer the night at the end of each working day so that an administrator can do all "daily Reports "of the several vehicles compile and test together the following morning.

It is therefore possible automatic transmission times to limit to a fixed period of time near a fixed time for example at "24:00" at night, so "from 24:00 (0:00) until 1:00 ".

For example, referring to the aforementioned first embodiment, let us assume that the power supply time of the vehicle is 9:32, so that a time (24:32) at which only the minute unit "32" of the power supply time 9:32 is extracted and a preset one numerical value "24" is the "hour unit", as the automatic transmission time of the vehicle 31 is set. When the power supply time of another vehicle 32 is assumed to be 10:30, is the automatic transmission time of this vehicle 32 24:30, so that the automatic transmission times among the several vehicles can be varied, while being limited to a time window range of "24:00 (0:00) to" 1:00. "Similarly, the automatic transmission times after the second Embodiment and the third embodiment are varied among the plurality of vehicles, being limited to a time window range of "24:00 (0:00) to 1:00".

at these embodiments At the end of each day, a work card is generated, creating a daily Workplace generated and the daily work report screen is updated. However, the work card unit is not on limited to one day and can be set to any period of time. For example can Work cards are generated on a monthly basis, so a monthly work report " and a "monthly Work report screen "updated becomes. It is also possible Work reports for to generate every rental period of a customer. That is, work cards can work in Rental units are generated, whereupon a "work report" is generated and the "work report screen" is updated.

If automatically transfer a work card on a monthly or per-rental basis it is also possible the aforementioned embodiments apply one to four so that the times of carrying out the automatic transmission be varied accordingly among the several vehicles.

at the first to fourth embodiments a case was provided in which the work card data is transmitted automatically become. However, you can the embodiments one to four on cases in which the different types mentioned in the description are used Types of mobile body information, this means Data such as the vehicle position (for example, the position history for one Day) or vehicle maintenance information (eg, oil pressure changes during one Day), automatically transferred become.

Further, in these embodiments, the case is provided that the data communication between the vehicles 31 . 32 . 33 ... and the server terminal 21 via a communications satellite 9 medium wireless communication 5 he follows. However, this communication system is an example, and any communication system can be used. That is, existing bumps can be used instead of satellite communications. The communication can also be done using an existing telephone line. Furthermore, the communication can also take place by means of an existing portable base station or a PHS base station.

Especially, if the vehicle is a construction machine, underground Work performed become. In this case, a communication failure occurs when the data communication using existing satellite communication devices he follows.

Data communication can therefore be accomplished by installing a new switch to ensure communication between the underground construction machine (e.g., the vehicle 31 ) and the over-the-ground communications satellites 9 and to perform the data communication via this switching station.

There may be two or more communication lines redundantly between the vehicles 31 . 32 . 33 ... and the server terminal 21 be provided. By thus providing redundant communication lines, the probability of finding "communication not possible" can be significantly reduced.

If a construction machine 31 rented, the rental fees are usually depending on the length of the rental period. In fact, however, there are both customers who own the construction machines 31 operate for long periods, as well as customers who use the construction machinery 31 hardly operate in a rental period of the same length. In this case, it is unfair and illegal to charge the same rental fee to both customers.

Therefore can the rental fees automatically calculated according to the duration of the engine operating time become.

For this purpose, a calculation is made, in which "operating time data" automatically from the vehicle 31 be transmitted in the server terminal 21 and the "operating time" is accumulated up to the present time. The relationship between the cumulative value of the operating period and the rental fee is determined in advance. Thus, the fee corresponding to the cumulative lifetime value up to the present time is calculated from this ratio. Processing for updating the site page "Daily Work Report Screen" by the latest rental fee is then performed in the server terminal 21 ,

If the WWW browser in the terminal 11 is turned on, the site data is taken from the server terminal 21 read via the WWW browser and the "daily work report screen" is displayed on a screen of the display device of the terminal 11 displayed. It is assumed that the rental period is from 21 January to 30 January. A fee of XXXXXXX yen, which corresponds to the cumulative lifetime value of the rental period (from January 21 to January 30) or in other words: the total value (49 hours, 6 minutes) of daily "service life" during the rental period, is displayed on the daily work report screen " from 40 displayed. From this display, the customer is able to easily and in real time on the screen obtain information regarding the rental fee, which corresponds to the duration of the engine operating time during the rental period.

at this embodiment will be the fee simply calculated according to the cumulative lifetime value.

In the reality The demand for construction equipment varies considerably depending on the period. In particular, the demand for construction equipment increases in periods of more concentrated Construction work. Even within a single day is the need in the afternoon higher than at night. Thus, you can the rental fees too according to the extent of Need to be fixed to a construction machine. In particular, the fees while Times of concentrated construction activity, where the demand for construction machinery increases, be higher while the fees during times outside the season can be set lower. The fees can also higher in the afternoon to be scheduled as at night. Thus, the fees are not only considering the cumulative lifetime value, but also taking into account the period during which the service life falls, the operating time during the day (afternoon, Night, etc.) and the operating time on the day (8:00, etc.).

It should be noted that in the aforementioned embodiments, the communication device 1 the Internet 2 should include. The communication device 1 However, the present invention is not limited thereto and may be constructed as a communication device including the Internet 2 not included. As long as communication similar to the communication described in the embodiment is made, the communication devices may be replaced by other communication devices. Further, in these embodiments, it is assumed that the communication devices 1 is a combination of wireless communication and communication over lines, but it can also be either wireless communication or communication over lines.

Further is in these embodiments a presentation format provided in the mobile body information displayed on a terminal as image data. However, the Mobile body information according to the invention Output as audio data to a terminal or output to Terminal for printing as print data. In short: the presentation format the mobile body information at a terminal is arbitrary.

In the embodiments Furthermore, the case is provided that several mobile body, the main construction equipment include, manage and monitor become. However, the present invention is not limited thereto and can be applied to a case where normal automobiles, motorcycles and can be managed and monitored.
