The transmission of the response request signal from the communication satellite 9 to the mobile work machine 31 is often unknown because it is unknown whether or not communication is possible, for example, in an environment where the mobile work machine 31 is in a poor communication state. Done. On the other hand, the mobile work machine 31
The confirmation of the presence / absence of a response request signal from the side to the communication satellite 9 is performed intermittently. Confirmation of the presence or absence of the response request signal is performed by sensing a radio wave indicating the response request signal transmitted from the communication satellite 9. Therefore, the communication satellite 9
The request can be reliably transmitted to the mobile work machine 31 from the side. The confirmation of the presence or absence of the response request signal (sensing of the radio wave indicating the response request signal) is performed at the time when the specific event occurs or after a lapse of a predetermined time from the occurrence of the specific event.

For example, it is possible to detect that the engine of the mobile work machine 31 has been started and to use this detection signal as a trigger to confirm the presence or absence of a response request signal. In this case 1
The presence or absence of the response request signal may be confirmed only at the time when the engine is first started in the day.

Further, it is possible to detect the occurrence of an abnormality in the mobile work machine 31 and confirm the presence or absence of a response request signal by using the detection signal as a trigger.

When a predetermined time has passed since the last transmission by the mobile work machine 31, the presence or absence of a response request signal is confirmed, and the next transmission can be performed.

The specific event or the predetermined time can be arbitrarily changed. You may make it change by input operation to the input device of the terminal 11.

As a result of checking the presence or absence of the response request signal, if it is determined that there is a response request signal, the mobile work machine 31
The server transmits data to the server terminal 21 via the communication satellite 9 to receive the electronic mail in the own mailbox. As a result, from the server terminal 21 to the mobile work machine 31
An email is sent to.

That is, the e-mail is transmitted to the network control station 7 via the Internet 2, and the data of the e-mail is subjected to protocol conversion. Then, the e-mail subjected to the protocol conversion is sent to the dedicated line 3. The e-mail is transmitted to the mobile work machine 31 via the satellite earth station 8, the feeder line 4, the communication satellite 9, and the wireless communication line 5 and received by the satellite communication antenna 58 of the mobile work machine 31.

The communication terminal 56 of the mobile work machine 31 reads the request information identification data D3 (“vehicle position”, “fuel amount”) from the e-mail received by the satellite communication antenna 58, and adds the request information identification data D3 to the request information identification data D3. The communication controller 54 is instructed to acquire the corresponding moving body information, that is, vehicle position data and fuel amount data in the mobile work machine 31.

In response to this, the communication controller 54
The data of the vehicle position currently detected by the GPS sensor 57 is transmitted to the communication terminal 56. Further, data indicating that the “fuel amount” should be acquired by the electronic controller 53 is described in the frame signal and transmitted to the signal line 52. The electronic controller 53 reads the description content of the frame signal, collects detection data of the current fuel amount from the sensor group 62 of the electronic controller 53, and describes the data in the frame signal. Then, the frame signal is transmitted to the communication controller 54 via the signal line 52. The communication controller 54 reads out the fuel amount data described in the frame signal and sends it to the communication terminal 56. As a result, in the communication terminal 56, the vehicle position data and the fuel amount data are taken in the reply e-mail as the mobile body information data D3 '.

Reply source identification data D2 indicating the replying mobile unit from the communication terminal 56 via the satellite communication antenna 58.
(Mobile work machine 31), return destination identification data D4 (terminal 12) indicating the terminal of the return destination, and mobile body information data D3 '(vehicle position data and fuel amount data) indicating mobile body information are provided in a predetermined manner. The data is transmitted to the communication satellite 9 as a reply e-mail in a data structure according to the communication protocol. D1 and D3 are also transmitted at the same time. D1 can be used as a distribution key for each communication billing destination. D3 is used for identifying the content of D3 '. Here, the reply source identification data D2 (“mobile work machine 31”) corresponds to the mail address of the mobile work machine 31. The reply destination identification data D4 (“terminal 12”) corresponds to the mail address of the display destination terminal 12.

The reply e-mail is received by the communication satellite 9 and further transmitted to the network control station 7 via the feeder line 4, the satellite earth station 8, and the dedicated line 3. The network control station 7 converts the data of the reply e-mail into a protocol, and sends the protocol-converted reply e-mail to the Internet 2.

The server terminal 21 receives the transmitted e-mail, reads the reply destination identification data D4, and reads the terminal 1 corresponding to the reply destination identification data D4 (“terminal 12”).
The contents of the e-mail are stored and stored in the second mailbox.

Further, the mobile object information extraction program is executed, and mobile object information data D 3 ′ (“vehicle position data”, “fuel amount data”) is extracted from the contents of the electronic mail stored in the mailbox of the terminal 12. At the same time, the reply source identification data D2 (“mobile work machine 31”) is extracted,
The latest vehicle position data and fuel amount data are stored in association with the address of the mobile work machine 31. In this way, the contents of all mobile unit information data MD are updated.

The server terminal (mail server) 21 transmits data requesting the terminal 12 to retrieve the electronic mail in the mailbox. The terminal 12 receiving this transmits data to the effect that the e-mail in the mailbox is received to the server terminal 21. As a result, an e-mail is transmitted from the server terminal 21 to the terminal 12. The data to be transmitted can be restricted by the security layer of D4.

When the electronic mail is received by the terminal 12 on the operator side of the mobile work machine carrier 35, the reply source identification data D2 (mobile work machine 31) and mobile body information data D3 '(vehicle position data) are obtained from the data of the electronic mail. Data and fuel amount data) are read out. Then, the content of the e-mail, that is, the current position of the mobile work machine 31 and the current fuel amount are displayed on the display screen of the terminal 12.

In response, the terminal 13 of the service car 34
As shown in FIG. 5, the icons of the mobile work machines 31A to 31D are displayed at the current position on the map, and the service meter increment is displayed for each of the mobile work machines 31A to 31D on the display screen 13a of FIG. . Here, for example, even if the mobile work machine 31D has moved with respect to the previous position (shown by a broken line), the current position (shown by a solid line) is displayed on the map on the screen 13a.

The terminal 13 stores and stores an automatic traveling route generation program. In this automatic patrol route generation program, when the current position of the vehicle 34 and a plurality of patrol candidate sites (mobile work machines 31A to 31D) are given, only the patrol candidate sites whose service meter increase value is larger than the set value are provided. A process of automatically generating the most efficient tour traveling route that passes through the selected tour candidate sites is performed. Therefore, when this automatic route generation program is executed, the display screen 13a of the terminal 13 displays the mobile work machine 31B with a large service meter increase value (“678H”, “500H”) from the current position of the vehicle 34,
A traveling route 108 indicated by a solid line that returns to the vehicle 34 again through the 31D is displayed.

The terminal 11 can grasp the work progress state of the transport vehicle 35 by receiving the e-mail. The input operation may be a voice input operation other than touch operations such as a click operation, a key operation, and a panel touch operation.

[0140] Therefore, the operator carries out the work by moving the transport vehicle 35 along the transport movement route 104 in accordance with the display screen 14a of the terminal 14, thereby loading and transporting (getting off).
Work can be done very efficiently. Furthermore, the return path of the transport vehicle 35 (vacant state) after getting off can be applied to transport of the other mobile work machines 31 to 33, and the efficiency can be further improved.

Further, it is also possible to transmit work instruction data from the terminal 11 on the manager side to a terminal equipped with the mobile work machine 31 such as a hydraulic shovel so that excavation work and the like can be performed efficiently.

For example, by transmitting to the terminal of the mobile work machine 31 data indicating the target of the excavation amount of the day, the end time of the work, and the current position of the dump truck at the loading destination, these are displayed on the display screen of the terminal. Then, the operator can operate the work machine in accordance with the display screen, and can efficiently perform a series of operations for excavating the earth and sand and loading the dump truck.

In this embodiment, the Internet 2
Data is sent and received using the above e-mail service. In this case, the server terminal 21 as a mail server
Checks for the presence / absence of e-mail in the mailbox at regular intervals. Therefore, the e-mail is sent to the terminal (for example, terminal 1).
There is a certain delay from the transmission in 1) to the actual reception by the mobile unit (for example, the mobile work machine 31) at the mail address.

In this embodiment, data transmission and reception are performed by satellite radio communication using the communication satellite 9. In satellite wireless communication, if the communication environment between the transmitter and the receiver is not good, such as when the maximum elevation angle of the satellite is small and it is not possible to see the moving object, the communication line 5 cannot be secured. Is performed. For this reason, after transmitting data from the communication satellite 9, the mobile unit (for example, the mobile work machine 3)
There is a delay due to the communication environment until it is actually received in 1).

As described above, in the communication system of the present embodiment, there is a time difference of, for example, several minutes between the transmission of the electronic mail at the requesting terminal and the reception of the electronic mail at the requesting mobile. In such a communication system having a low real-time property, there is a fear that the operator of the requesting terminal may feel uneasy due to the unknown communication state, thereby affecting the work efficiency. In addition, since the communication state is unknown, the electronic mail having the duplicate content may be retransmitted, which may affect the communication cost.

[0146] Therefore, it is desired to display the communication state with each mobile object on the display screen of the terminal to avoid a decrease in work efficiency and an increase in communication cost due to unknown communication state.

Further, in the present embodiment, a plurality of terminals request a mobile unit for mobile unit information. Therefore, it is not possible to determine how new the mobile body information currently obtained is (when the mobile body information is requested) by only one terminal. Therefore, the display screen of the terminal displays the time lapse since the last request for the mobile unit, and displays information on the management of the mobile unit as to how new the currently obtained mobile unit information is. It is desired to inform the operator.

The embodiment described below meets these requirements.

That is, as shown in FIG. 31, an icon (a picture of a hydraulic shovel, a picture of a service car, a picture of a trailer, etc.) as a moving object identifier is provided on the terminal 11 in association with each of a plurality of moving objects 31 to 35. ) Is displayed. Then, when an e-mail requesting mobile object information is transmitted from the request source terminal 11 to the request destination mobile work machine 31, the icon of the mobile work machine 31 is displayed in FIG. The display content changes in the manner shown.

That is, as shown in FIG.
1 as the communication state between the mobile work machine 31 and the communication procedure changes to “no request”, “requesting”, “reply”, and “no reply”. The color changes to "blue", "yellow", "green", "red".

This will be described with reference to the flowchart shown in FIG.

FIG. 15 shows a procedure of a process of changing the display according to the communication procedure. This processing is executed by the server terminal 21, and the processing result is displayed on the display screen of the terminal 11.

First, in the initial state, the icon of the mobile work machine 31 is displayed in “blue” corresponding to “no request” (step 201).

Here, an electronic mail requesting the mobile body information is transmitted from the requesting terminal 11 to the mobile work machine 31 of the request destination, and the electronic mail is stored in the mailbox addressed to the mobile work machine 31. (Decision Y in step 202
ES), the icon of the mobile work machine 31 transits to a "yellow" color display corresponding to "requesting" (step 20).
3).

Here, when the electronic mail returned from the mobile work machine 31 of the request destination is stored in the mailbox (YES in step 204), the icon of the mobile work machine 31 corresponds to “reply”. The display transitions to a “green” color display (step 207). One day has passed since the state transited to the "reply with" state (determination YE in step 208).
S), the icon of the mobile work machine 31 returns to the "blue" display corresponding to "no request" (step 201). In this case, when the returned mobile unit information is transmitted to the display destination terminal (for example, terminal 12) and displayed, step 2
It is also possible to return from step 07 to step 201 to return to the display of “blue” corresponding to “no request”.

On the other hand, if the e-mail to be returned from the mobile work machine 31 of the request destination is not stored in the mailbox (NO in step 204, YES in step 205), the wireless communication line 5 is secured. Is determined to be difficult, the icon of the mobile work machine 31 transits to a "red" display corresponding to "no reply" (step 206).

In the above description, it is assumed that the terminal 11 requests the mobile work machine 31 for mobile body information.
Each of the mobile units 31, 32, 33, 3 from each of the terminals 11, 12,.
Similarly, in the case of requesting the mobile unit information to the terminals 4 and 35, the icon of the requested mobile unit changes according to the communication state in the request source terminal.

As described above, according to the present embodiment, even when communication means having low real-time properties is used, the display content changes in accordance with the communication state, and the “degree of communication delay” is set to the terminal 11. Can be recognized on the display screen. Also, the request is not duplicated with other terminals. For this reason, it is possible to avoid a decrease in work efficiency and an increase in communication cost due to an unknown communication state.

Next, the display screen of the terminal 11 displays the time lapse since the last request for the mobile object, and displays the current information of the mobile object to determine how new the mobile object information is. An embodiment in which management information can be notified to an operator will be described.

That is, as shown in FIG.
.. And the mobile work machine 31, that is, each terminal 1
The elapsed time from the last request to the mobile work machine 31 from 1, 12,... Is “not requested within one day”, “not requested from one to three days”, “requested from three days to one week” The color of the icon of the mobile work machine 31 changes to “blue” in response to the change “not performed” or “not requested for one week or more”.
("No request # 0"), "Yellow"("No request # 1"),
It changes to "pink"("no request # 2") and "red"("no request # 3").

As shown in FIG. 18, an e-mail requesting mobile information is transmitted from the terminals 11, 12,... To the requested mobile work machine 31, and the e-mail is stored in a mailbox addressed to the mobile work machine 31. When stored (Step 3
01, YES), the timer is reset (step 305), and the icon of the mobile work machine 31 is changed to “No request #
"0" is displayed (step 3).

If the elapsed time since the timer was reset is within one day (NO in step 302), the icon of the mobile work machine 31 is displayed as “No request #
The display is maintained in the "blue" color corresponding to "0" (step 306).

If the elapsed time since the timer was reset is more than one day and less than three days (step 3
02 (YES in step 303, NO in step 303), the icon of the mobile work machine 31 transits to a “yellow” color display corresponding to “no request # 1” (step 307).

If the elapsed time since the reset of the timer is more than three days and less than one week (YES in step 303, NO in step 304), the icon of the mobile work machine 31 is changed to “Request”. The display transitions to a “pink” display corresponding to “none # 2” (step 308).

If the elapsed time since the timer was reset exceeds one week (determination Y in step 304)
ES), the icon of the mobile work machine 31 is “No request #
"3" is displayed (step 3).
09).

While the timer is counting, the terminal 11, 12,... Sends an e-mail requesting mobile body information to the requested mobile work machine 31, and the e-mail is stored in the mailbox addressed to the mobile work machine 31. (Step 30
1, the timer is reset (step 3).
05), the icon of the mobile work machine 31 is “No request #
"0" is displayed (step 3).
06).

In the above description, it is assumed that the time elapsed since the last request was issued to the mobile work machine 31 on the terminal 11 is displayed, but the other mobile units 32 to 35 are similarly displayed. Is done. Also, the other terminals 12... Display the elapsed time since the last request for each of the mobile units 31, 32, 33, 34, 35.

As described above, according to this embodiment, it is possible to recognize on the display screen of the terminal the progress situation since the last request for each of the moving bodies 31 to 35.
, It is possible to know management information on how new mobile body information currently obtained is.

The above embodiment can be variously modified. 16 (b) to 16 (d), FIG. 17, FIG.
FIG. 20 will be described.

Next, the display screen of the terminal 11 displays the elapse of time since the last reception of the e-mail indicating the moving body information from the moving body, and shows how much the currently obtained moving body information is newer. An embodiment will be described in which an operator can be informed of management information of a mobile object as to whether or not the mobile device is a mobile device. Here, the term "incoming" means that an e-mail indicating the mobile information is returned from the mobile, and an e-mail indicating the mobile information is automatically transmitted from the mobile without a request from the terminal side as described later. Including both cases.

That is, as shown in FIG. 19, the state of communication with the mobile work machine 31, that is, the elapsed time from the last incoming call (reply, automatic call) from the mobile work machine 31 to the server terminal 21 is “Incoming within one day. The color of the icon of the mobile work machine 31 changes to “blue” according to the change to “none”, “no call received for one to three days”, “no call received for three days to one week”, and “no call received for one week or more”. "No incoming call # 0"), "Yellow"
("No call # 1"), "Pink"("No call #
2 ") and" red "(" No incoming call # 3 ").

As shown in FIG. 19, when a reply from mobile work machine 31 or an e-mail automatically transmitted from mobile work machine 31 is stored in the mailbox of server terminal 21 (determination YES in step 401), the timer is started. The icon is reset (step 405), and the icon of the mobile work machine 31 transits to a “blue” display corresponding to “no incoming call # 0” (step 406).

If the elapsed time since the timer was reset is within one day (NO in step 402), the icon of the mobile work machine 31 is displayed as “No incoming call #
The display is maintained in the "blue" color corresponding to "0" (step 406).

If the elapsed time since the timer was reset is more than one day and less than three days (step 4
02 (YES in step 403, NO in step 403), the icon of the mobile work machine 31 transits to a “yellow” color display corresponding to “no incoming call # 1” (step 407).

If the elapsed time since the timer was reset is more than three days and less than one week (YES in step 403, NO in step 404), the icon of the mobile work machine 31 is displayed as “incoming call”. The display transits to a “pink” display corresponding to “none # 2” (step 408).

If the elapsed time since the reset of the timer exceeds one week (determination Y in step 404)
ES), the icon of the mobile work machine 31 is “No incoming call #
"3" is displayed (step 4).
09).

When a reply from the mobile work machine 31 or an e-mail automatically transmitted by the mobile work machine 31 is stored in the mailbox of the server terminal 21 while the timer is counting (YES in step 401), the timer is reset. (Step 405), the icon of the mobile work machine 31 transits to a “blue” display corresponding to “No incoming call # 0” (Step 406).

In the above description, it is assumed that the time elapsed since the last incoming call from the mobile work machine 31 is displayed. However, the other mobile units 32 to 35 are displayed similarly. Each of the other mobile terminals 3 also
The elapsed time from the last incoming call from 1, 32, 33, 34, 35 is displayed.

As described above, according to the present embodiment, it is possible to recognize the progress situation since the last incoming call from each of the mobile units 31 to 35 on the display screen of the terminal.
It is possible to know the management information on how new the mobile body information currently obtained for the mobile terminal 5 is. When the mobile unit (for example, the mobile unit 31) is automatically transmitted at a regular cycle, the mobile unit 3 is determined based on the display content of the time elapsed since the last incoming call from the mobile unit 31.
The terminal can determine whether or not some trouble in communication has occurred when the automatic transmission 1 is performed.

Next, the elapsed time from when a request is made to the mobile body until a response is made is displayed, and whether or not communication is normally performed can be determined on the display screen of the terminal 11. The mode will be described with reference to FIG.

That is, as shown in FIG. 20, as the time during which there is no response after the last request from the terminal 11 to the mobile work machine 31 changes, that is, “no response for one minute or less” , "No response for 1 to 3 minutes or less", "no response for 3 to 10 minutes", or "no response for 10 minutes or more", the color of the icon of the mobile work machine 31 becomes "green"("response"). None # 0 ”),“ Yellow ”
("No response # 1"), "Pink"("No response #
2 ") and" red "(" No response # 3 "). Also, when there is no request (response) from the terminals 11, 12,... To the mobile work machine 31, it is displayed in "blue"("norequest").

As shown in FIG. 20, an e-mail requesting the mobile body information is transmitted from the requesting terminal 11 to the requesting mobile work machine 31, and in response to this, the requesting mobile work machine 31 is sent. Is stored in the mailbox (determination YE in step 501)
S), the icon of the mobile work machine 31 transits to “blue” corresponding to “no request” (step 506).

In the state where the reply electronic mail from the mobile work machine 31 of the request destination is not stored in the mailbox (NO in step 501), the following step 5
02 is transferred.

In step 502, an electronic mail requesting mobile information is transmitted from the requesting terminal 11 to the mobile work machine 31 of the request destination, and whether the electronic mail is stored in the mailbox addressed to the mobile work machine 31 is determined. That is, it is determined whether a request has been made (step 502).

If there is a request (YES in step 502), the timer is reset, and if the elapsed time since the timer was reset is within one minute (NO in step 503), the movement is performed. The icon of the work machine 31 transits to a “green” display corresponding to “no response # 0” (step 507).

If the elapsed time since the timer was reset is more than one minute and less than three minutes (step 5).
03 (YES in step 504; NO in step 504), the icon of the mobile work machine 31 transits to a “yellow” color display corresponding to “no response # 1” (step 508).

If the elapsed time since the reset of the timer is more than 3 minutes and not more than 10 minutes (judgment in step 504, judgment in step 505), the icon of the mobile work machine 31 is displayed as “Response”. The display shifts to a “pink” display corresponding to “none # 2” (step 509).

If the elapsed time since the timer was reset exceeds 10 minutes (YES in step 505), the icon of the mobile work machine 31 is displayed as “No response #
"3" is displayed (step 5).
10).

When the electronic mail returned from the mobile work machine 31 of the request destination is stored in the mailbox while the timer is counting (YES in step 501), the icon of the mobile work machine 31 changes to "No request". (Step 506).

In the above description, it is assumed that the elapsed time from the request to the mobile work machine 31 until the response is displayed on the terminal 11 is displayed.
The same applies to 2 to 35. Also, in the other terminals 12, the respective mobile units 31, 32, 33, 34,
The elapsed time from the request to 35 is displayed.

As described above, according to the present embodiment, the elapsed time from when a request is issued to a mobile object until a response is received is displayed, so that whether communication is normally performed or not is determined. Can be easily determined on the display screen on the terminal.

In the above description, as shown in FIG. 16A, the color of the entire icon of the mobile work machine 31 is changed and displayed according to the communication state between the terminal 11 and the mobile work machine 31. However, the combination of the colors of the icons, the color scheme, the pattern of the fill, and the like may be changed. Further, components other than the color may be changed.

For example, as shown in FIG.
The shape of the icon of the mobile work machine 31 may be changed and displayed according to the communication state between the mobile work machine 31 and the mobile work machine 31. For example, if it ’s an excavator icon,
The position and roundness of the work machine can be changed.

As shown in FIG. 16 (c), the size of the icon of the mobile work machine 31 may be changed and displayed according to the communication state between the terminal 11 and the mobile work machine 31. For example, in the case of “requesting” shown in FIG. 16C, the size of the icon of the hydraulic shovel changes from large to middle to middle to large.

Further, as shown in FIG. 16D, the movement of the icon of the mobile work machine 31 may be changed and displayed according to the communication state between the terminal 11 and the mobile work machine 31. For example, in the case of “no request” shown in FIG. 16C, the icon of the excavator stops, in the case of “requesting”, the icon of the excavator rotates, and in the case of “with reply”, The icon of the excavator moves linearly, and in the case of “no response”, the icon of the excavator jumps.

In addition, the blinking pattern of the icon of the mobile work machine 31 may be changed and displayed according to the communication state between the terminal 11 and the mobile work machine 31. For example, it is conceivable to change the blinking cycle.

Instead of changing the picture of the mobile work machine 31, an identification code such as a character for identifying the mobile work machine 31 may be changed. For example, it is conceivable to change the color of the character indicating the vehicle body number, the nickname, or the like of the mobile work machine 31, or to blink the character.

As described above, for example, as a result of the processing shown in FIG. 15, as shown in FIG.
On the upper display screen, a plurality of mobile work machines 31, 32, 3
The icons 3, 36, 37, and 38 are displayed in association with the moving body information (“vehicle number”, “position”, and “service meter”). In this case, as shown in FIG. 17 (a), each mobile work machine 31, 32, 33, 36, 3
7, 38 icons can be displayed on the screen in a preset order.

As shown in FIG. 17B, the icons of the mobile work machines 31, 32, 33, 36, 37, and 38 are rearranged according to the communication state, and the mobile machine corresponding to the "request in progress" is changed. The icons of the work machines 31 and 32 are displayed at the upper level, and the work machines 33 and 36 corresponding to “no request” are displayed.
37 icons can be displayed at a lower level.

As shown in FIG. 17C, of the icons of the mobile work machines 31, 32, 33, 36, 37, and 38, the mobile work machines 31, 3 corresponding to "Requesting"
Only the second icon may be extracted and displayed.

As described above, according to the present embodiment, the display content of the terminal is changed in accordance with the change in the communication state. Therefore, it is possible to prevent a decrease in work efficiency due to an unknown communication state and to increase the communication cost. Can be prevented. Also, management information (such as whether maintenance and inspection have been performed recently) can be obtained from the display screen as to how new the moving body information of each moving body is.

The embodiment in which the display content of the terminal is changed according to the change in the communication state can be applied to any communication system without being limited to the communication system shown in FIG. Any communication system that includes at least two communication stations and performs communication between the two communication stations is applicable.

Next, a description will be given of an embodiment in which unnecessary power consumption in communication can be suppressed by intermittently turning off the power supply on the mobile bodies 31 to 35 side.

A mobile work machine such as a construction machine has a long time period during which the engine is not operating (that is, a time period during which the power is turned off).

In FIG. 21, even if the engine is turned off, the battery 63 (the rated voltage 24
If V) and the communication terminal 56 are always electrically connected, the battery 63 is not charged by the generator (alternator) because the engine is not running. Therefore, the discharge in the battery 63 proceeds rapidly. On the other hand, if the electrical connection between the battery 63 and the communication terminal 56 is always off while the engine is off, the plurality of terminals 1
Communication with 1, 12,... Becomes impossible. Therefore, when the terminal 11, 12,... Requests the mobile body information when the engine is off, it cannot respond to the request.

Therefore, in the embodiment described below, a moving body 31 such as a construction machine which has a long engine inactive time is used.
Even if the number of terminals is less than 35, the plurality of terminals 11
12 so as to be able to respond to requests from the terminals 11, 12, and to suppress unnecessary power consumption. FIG. 21 shows the configuration of this embodiment.

As described in FIG. 2, the communication terminal 56 is provided in the vehicle body of the mobile work machine 31. The power terminal of the communication terminal 56 is electrically connected to the battery 63. A main power supply circuit is provided in the communication terminal 56, and power is consumed by supplying power of the battery 63 to the main power supply circuit. Communication terminal 5
6, an internal program (software timer) is stored or an internal power supply circuit (hard timer) is incorporated. By these, the driving of the main power supply circuit is intermittently turned on and off, and the main power supply circuit is periodically turned on and off. The circuit operates to save power.

The level of the engine key switch signal S1 input to the sleep control terminal of the communication terminal 56 is monitored by software, and when the signal is an ON signal and the main power supply circuit of the communication terminal 56 is off, the main power supply circuit Is forcibly driven. Further, the main power supply circuit may be configured to be driven by hardware.

That is, when an off signal (signal of logic “0” level) of the engine key switch signal S 1 is input to the sleep control terminal of the communication terminal 56, the main power supply circuit in the communication terminal 56 and the battery 63 Is turned on and off at a predetermined duty ratio, the driving of the main power supply circuit is turned on and off, the start of the communication terminal 56 is turned on and off, and the communication process is performed at a constant cycle (the communication terminal 56 Sleep function is on).

The main power supply circuit in communication terminal 56 and battery 63 are electrically connected in response to input of ON signal (signal of logic "1" level) of engine key switch signal S1 to sleep control terminal of communication terminal 56. , The main power supply circuit is driven, the communication terminal 56 is activated, and communication processing is performed (the sleep function of the communication terminal 56 is turned off (forcibly released)). Therefore, while the engine is on, the communication terminal 56
Is in a running state.

On the other hand, the power terminal of the communication controller 54 is electrically connected to the battery 63 via the engine key switch 64. When the engine key switch 64 is turned off, the communication controller 54 and the battery 6
3 and the operation of the engine of the mobile work machine 31 is stopped. When the engine key switch 64 is turned on, the communication controller 5
4 outputs an ON signal (logic "1" level signal) of the engine key switch signal S1 to the sleep control terminal of the communication terminal 56.

Next, processing performed by the communication terminal 56 will be described with reference to the timing chart shown in FIG.

FIG. 7A shows an operation signal S1 of the engine key switch 64, and FIG. 7B shows a communication state between the communication terminal 56 and the communication satellite 9. Logic "1" during communication
Shown by level. FIG. 7C shows the activated state of the communication terminal 56. A logic “1” level corresponds to a startup state (power saving operation is off), and a logic “0” level corresponds to a startup off (sleep) state (power saving operation is on). The communication terminal 56 is activated by the duty ratio D (= (τ /
T) × 100%), which is turned on and off intermittently. At the timing when the power saving operation is turned off and the communication terminal 56 is started, the movement of the current position, the service meter value, the remaining fuel amount, the battery voltage, the vehicle body error code, etc. from the communication terminal 56 to the communication satellite 9 as necessary. A signal indicating body information is transmitted.

As shown in FIG. 7, the communication terminal 56 is always activated when the engine key switch signal S1 is kept on.

When the engine key switch signal S1 is switched from on to off, the communication terminal 56 is activated at the duty ratio D (= (τ / T) × 100) as shown by the arrow a.
%), It is turned on and off intermittently (sleep function is on).

FIG. 8B is a timing chart showing ON / OFF of the power saving operation corresponding to FIG. 7C, and FIG. 8C is a timing chart of a call signal from the communication satellite 9 to the communication terminal 56. The transmission state is shown. Logical "1"
The level indicates transmitting.

As shown in these figures, during a certain time (starting cycle) T, the starting time τ, that is, the communication satellite 9
There is a time that can be transmitted and received between (Figure 8 (c)
). The expected value of the communication response time is T / 2 (the average is T / 2). Power consumption can be suppressed to τ / T. In order to enable transmission and reception between the communication terminal 56 and the communication satellite 9 which are operating at a power saving period T, the communication satellite 9 sends a signal to the communication terminal 56 continuously for a period of time T or more. (Fig. 8 (b),
(C)). The activation cycle T is the urgency of communication, the communication satellite 9
Is determined according to the safety factor for the duration of the signal being transmitted from.

It is necessary to secure the start time τ longer than the time required for the transmission / reception procedure. However, the effect of power saving is greater as the startup time τ is shorter.

As described above, by periodically activating the communication terminal 56 at the period T, it is possible to secure the expected value of the communication response time and to suppress the power consumption.

However, even if the engine key switch signal S1 is switched from on to off as shown in FIG.
If the communication is being performed between the communication terminal 56 and the communication satellite 9 as shown by the arrow c, the sleep function is turned on at the time when the communication is completed as shown by the arrow d.

When the engine key switch signal S1 is switched from off to on, the sleep function is forcibly released as shown by the arrow b.

As described above, according to the present embodiment, the sleep function is forcibly released when the engine is running, and the communication terminal 56 is always activated while the engine is running. It is possible to transmit mobile body information such as a typical vehicle abnormality, thereby ensuring safety. Further, even if the engine stops operating, if communication is in progress, the communication terminal 56 is kept activated until the end of communication, so that communication can be reliably performed.

The duty ratio D can be changed according to the terminal voltage of the battery 63.

The voltage of the battery 63 is input to the battery voltage input circuit, and the duty ratio D changes according to the characteristics shown in FIG.

That is, as the voltage of the battery 63 becomes lower, the duty ratio D becomes smaller, the starting cycle T becomes longer, and further reduction of the voltage of the battery 63 is suppressed.

Further, with a characteristic similar to that shown in FIG. 8A, the duty ratio D is reduced and the starting cycle T is lengthened as the operating time of the engine is shortened, so that the voltage of the battery 63 is further reduced. May be suppressed.
The operating time of the engine is obtained from the increase value of the service meter. The continuous operation time of the engine before the sleep function is turned on (before the intermittent power saving operation is started) is obtained from the increase value of the service meter, and the duty ratio D changes according to the continuous operation time. . In this case, there is no need to provide a battery voltage input circuit.

According to the configuration shown in FIG. 21, the power saving operation is performed by the processing in communication terminal 56.
There is an advantage that it is not affected by other devices or wiring abnormalities. The configuration shown in FIG. 22 may be employed instead of the configuration shown in FIG. That is, a device other than the communication terminal 56, such as the communication controller 54, is provided with a power saving operation control function when the engine key switch 64 is turned off, and the communication controller 54 establishes an electrical connection between the communication terminal 56 and the battery 63. On / off control may be performed intermittently.

That is, as shown in FIG.
Of the battery 63 via the power switch 65
Is electrically connected to As the power switch 65 is turned off, the electrical connection between the communication terminal 56 and the battery 63 is cut off.

On the other hand, the power terminal of the communication controller 54 is electrically connected to the battery 63. The operation signal S1 of the engine key switch 64 is transmitted to the communication controller 5
4 is input. A signal S3 indicating a communication state is input from the communication terminal 56 to the communication controller 54. If the communication terminal 56 is communicating with the communication satellite 9, the communication state signal S
3 is a logical "1" level.

In the communication controller 54, a software timer is stored or a hard timer is incorporated, and a power switch drive signal S
2 is output.

In the communication controller 54, the same processing as that described with reference to FIG. 7 is executed.

FIG. 7A shows an operation signal S1 of the engine key switch 64 inputted to the communication controller 54, and FIG.
4 shows a communication status signal S3 input to the power switch 4, and FIG. 7C shows a power switch drive signal S2 output from the communication controller 54 to the power switch 65.

Therefore, as in the configuration shown in FIG. 21, when the operation of the engine is stopped (signal S1 is turned off), the start of communication terminal 56 is controlled to be turned on and off at a predetermined duty ratio D (signal S2 is turned on). ,off). When the engine is operated (the signal S1 is turned on), the sleep function is forcibly released and the communication terminal 56 is always activated while the engine is operating (the signal S2 is turned on). Also, even if the engine stops operating, if communication is in progress (S3 is on), the communication terminal 56 remains activated until communication ends (S2 is on).

In the same manner, the duty ratio D can be changed according to the terminal voltage of the battery 63 or the operating time of the engine.

The above embodiment can be variously modified. Hereinafter, FIGS. 13, 23, 24, and 25 will be described.

The duty ratio D is determined by
May be changed according to the position information.

FIG. 23 shows an embodiment in which the duty ratio D is changed in accordance with the relative moving distance of the mobile work machine 31 with respect to the set range.

FIG. 23A shows how the activation cycle T is shortened and the teat ratio D is increased as the mobile work machine 31 deviates from the set range 117 on the map.

That is, most ordinary automobiles and the like move by themselves. On the other hand, in the case of the mobile work machine 31 such as a construction machine, the situation in which the user travels a long distance by self-traveling is rare. In most cases, the operation of the engine of the own vehicle is stopped and the mobile work machine 31 is mounted on a trailer. I do.
In this case, the trailer 35 managed on the terminal 11 side
The mobile work machine 31 is not always loaded and transported, and the mobile work machine 31 may be loaded on a trailer that is not managed and may be illegally taken overseas. In addition, there is a possibility that the mobile work machine 31 may be carried without care by a trailer 35 to a work site which is not transported carelessly and is not administratively permitted.

Therefore, when the operation of the engine of the mobile work machine 31 is stopped, the mobile work machine 31 is controlled in response to a request from the terminal 11 while suppressing power consumption associated with communication.
Is displayed on the terminal 11 and the mobile work machine 3
It is necessary to manage and monitor one movement trajectory.

Then, on the map on the display screen of the terminal 11,
A predetermined range 117 where the mobile work machine 31 would normally be located is set. This setting range 117
Is, for example, a management area in charge of the manager of the terminal 11, a work site that is administratively approved, and the like.

The activation of the communication terminal 56 of the mobile work machine 31 is performed at a predetermined duty ratio D as shown in FIG.
It is turned on and off intermittently at (= (τ / T) × 100%). Then, the power saving operation is turned off (the power switch drive signal S2 is turned on) as shown in FIG.
In response to a request from the terminal 11, the communication terminal 56 sends the current position (in addition to the service meter value, the remaining fuel amount, the battery voltage, the vehicle body error code, etc.) to the communication satellite 9 in response to a request from the terminal 11. (Information may be included). As a result, the sequential movement position of the mobile work machine 31 is displayed on the terminal 11 which is the display destination terminal.

The position of the mobile work machine 31 is detected by the GPS sensor 57 as shown in FIG. In this case, if the power consumption of the GPS measuring devices (the GPS antenna 59, the GPS sensor 57, and the communication controller 54) is small, these GPS measuring devices can be electrically connected directly to the battery 63 to always operate. When the power consumption of these GPS measuring devices is large, the sleep function is turned on in the same manner as the communication terminal 56 to turn on and off the power saving operation. Only at the time), the GPS measurement device may be operated to measure the position.

In the mobile work machine 31, the GPS sensor 57
Is compared with the position of the boundary of the setting range 117, and a process of changing the start cycle T according to the comparison result is executed.

FIG. 23D shows how the activation cycle T changes in accordance with the relative position (elapsed time) of the mobile work machine 31 with respect to the set range 117.

As shown in FIG. 23A, when the mobile work machine 31 exists at the positions A and B within the normal setting range 117, the start cycle T becomes the maximum cycle T1.

However, when the mobile work machine 31 reaches the boundary position C of the normal setting range 117, it is determined that the mobile work machine 31 has deviated from the normal range and an abnormal situation has occurred (movement outside the permitted area), and detailed information on the movement locus is provided. Is obtained, the activation cycle T is a cycle T2 shorter than the maximum cycle T1 (see FIG. 23D).

When the mobile work machine 31 is in the normal setting range 11
A position D further separated from the boundary position 7 by a predetermined distance L0
At this point, the startup cycle T becomes a cycle T3 shorter than the cycle T2 in order to obtain more detailed information of the movement trajectory (see FIG. 23D). Thereafter, the normal setting range 117
The starting cycle T is set to T4 as the distance from the vehicle increases.
(<T3)... In order to finally set the period to 0 (duty ratio D = 1).

As shown in the graph of FIG.
The activation cycle T may be continuously shortened as the distance L from the boundary position of the normal setting range 117 increases.

As the activation period T of the communication terminal 56 becomes shorter, the response to the request from the terminal 11 becomes faster. As will be described later, when the mobile work machine 31 is performing automatic transmission, the transmission interval of mobile body information called position information is shortened.

Therefore, as the mobile work machine 31 moves away from the normal setting range 117, the display screen of the terminal 11, which is the display destination terminal, displays a more detailed movement trajectory (between the displayed movement positions). A moving trajectory with a short time interval) is displayed. Therefore, it is possible to quickly and accurately deal with an abnormal situation such as movement outside the permitted area. Moreover, as the mobile work machine 31 moves away from the normal setting range 117, the on / off duty ratio D of the activation of the communication terminal 56 is increased. It can also perform accurate monitoring for

FIG. 23B shows a startup cycle T as the mobile work machine 31 enters the set range 118 on the map.
Is shortened and the teat ratio D is increased.

As in FIG. 23 (a), a predetermined range 118 is set on the map on the display screen of the terminal 11 where the mobile work machine 31 would not be brought in if it was normal. The setting range 118 is an abnormal area, for example, an overseas port, a dangerous area for work, an illegal work area such as a nature protection area, or the like.

The mobile work machine 31 compares the position detected by the GPS sensor 57 with the boundary position of the set range 118 in the same manner as described with reference to FIG. A process for changing the start cycle T is executed.

FIG. 23D shows how the activation cycle T changes in accordance with the relative position (elapsed time) of the mobile work machine 31 with respect to the set range 118.

As shown in FIG. 23B, when the mobile work machine 31 exists at the positions A and B outside the abnormal setting range 118, the startup cycle T becomes the maximum cycle T1.

However, when the mobile work machine 31 reaches the boundary position C of the abnormal setting range 118, it is determined that an abnormal situation has occurred (intrusion into a dangerous area), and the starting cycle is determined in order to obtain detailed information on the moving locus. T is a cycle T2 shorter than the maximum cycle T1 (see FIG. 23D).

When the mobile work machine 31 is in the abnormal setting range 11
Position D that has entered the predetermined distance L0 further from the boundary position 8
At this point, the startup cycle T becomes a cycle T3 shorter than the cycle T2 in order to obtain more detailed information of the movement trajectory (see FIG. 23D). Thereafter, abnormal setting range 118
The starting cycle T is set to T4 as the intrusion distance into
(<T3)... In order to finally set the period to 0 (duty ratio D = 1).

As shown in the graph of FIG.
The activation cycle T may be continuously shortened as the distance L to the boundary position of the abnormal setting range 118 increases.

As the mobile work machine 31 enters the abnormal setting range 118 in this manner, the display screen of the terminal 11 which is the display destination terminal displays a more detailed movement trajectory (between displayed movement positions). A moving trajectory with a short time interval) is displayed. Therefore, it is possible to quickly and accurately deal with an abnormal situation such as intrusion into a dangerous area. Moreover, as the mobile work machine 31 enters the abnormal setting range 118, the duty ratio D of ON / OFF of the activation of the communication terminal 56 is increased, so that the power consumption associated with communication is suppressed and at the same time the abnormality is reduced. Precise monitoring can also be performed.

Note that the present invention can be applied not only to the monitoring of the abnormal situation assumed in FIGS. 23A and 23B, but also to the monitoring of the route from the disposal of the mobile work machine 31 to the disposal thereof. .

In the embodiment shown in FIGS. 23A and 23B, the distance L to the boundary between the setting ranges 117 and 118 is set to L.
The activation period T is uniquely determined from the above. However, in addition to the distance L, the activation period T is further considered in consideration of the direction, the geographical information of the surrounding area, the type of the moving object, the usage period of the moving object, and the like.
May be determined.

Further, as shown in FIG.
The duty ratio D may be changed in accordance with the amount of change in the position.

The activation of the communication terminal 56 of the mobile work machine 31 is performed at a predetermined duty ratio D as shown in FIG.
It is turned on and off intermittently at (= (τ / T) × 100%). Then, the power saving operation is turned off (the power switch drive signal S2 is turned on) as shown in FIG.
In response to a request from the terminal 11, the communication terminal 56 sends the current position (in addition to the service meter value, the remaining fuel amount, the battery voltage, the vehicle body error code, etc.) to the communication satellite 9 in response to a request from the terminal 11. (Information may be included). As a result, the sequential movement position of the mobile work machine 31 is displayed on the terminal 11 which is the display destination terminal.

The position of the mobile work machine 31 is detected by the GPS sensor 57 as shown in FIG. In this case, if the power consumption of the GPS measuring devices (the GPS antenna 59, the GPS sensor 57, and the communication controller 54) is small, these GPS measuring devices can be electrically connected directly to the battery 63 to always operate. When the power consumption of these GPS measuring devices is large, the sleep function is turned on in the same manner as the communication terminal 56 to turn on and off the power saving operation. Only at the time), the GPS measurement device may be operated to measure the position.

In the mobile work machine 31, the GPS sensor 57
, Circles 119 and 12 having a radius S centered on the current position detected at the time of this activation and the position detected at the time of the previous activation.
Then, a process of comparing the start position T with the boundary position of 0... Is performed according to the comparison result.

FIG. 24 (b) shows the activation cycle T depending on whether the mobile work machine 31 has escaped outside the circles 119, 120,.
Shows a state in which changes.

As shown in FIG. 24A, first, the position A of the mobile work machine 31 is detected by the GPS sensor 57, and a circle 119 having a radius S (km) centered on the position A is set on the map. You. The initial startup cycle T is set to the maximum cycle T1. Therefore, the communication terminal 56 is activated after the period T1. It is assumed that the position detected by the GPS sensor 57 at that time is the position B inside the circle 119. In this case, the startup cycle T is kept at the maximum cycle T1. Furthermore, the period T
It is assumed that the communication terminal 56 is activated one time later and the position detected by the GPS sensor 57 at that time is a position C outside the circle 119. In this case, the radius S around the position C
(Km) circle 120 is set on the map,
The starting cycle T is changed to a cycle T2 shorter than the maximum cycle T1.

For this reason, the communication terminal 56 is activated after the period T2. It is assumed that the position detected by the GPS sensor 57 at that time is the position D inside the circle 120. In this case, the activation cycle T is kept at the cycle T2. Further, it is assumed that the communication terminal 56 is activated after the period T2, and the position detected by the GPS sensor 57 at that time is the position E outside the circle 120. In this case, the radius S around the position E
(Km) circle 121 is set on the map,
The starting cycle T is changed to a cycle T3 shorter than the cycle T2. Further, it is assumed that the communication terminal 56 is activated after the period T3, and the position detected by the GPS sensor 57 at that time is a position F outside the circle 121. In this case, a circle 122 having a radius S (km) centered on the position F is set on the map, and the activation cycle T is shorter than the cycle T3.
It is changed to 4. Therefore, the communication terminal 56 is activated after the cycle T4. It is assumed that the position detected by the GPS sensor 57 at that time is the position G inside the circle 122. In this case, the activation cycle T is returned from the cycle T4 to a longer cycle T3 (see FIG. 24B).

In the embodiment shown in FIG. 24A, areas of circles 119, 120,... Having a radius S are set.
Instead, a square area having one side of S may be set.

In the case of a square area, when comparing the current position detected by the GPS sensor 57 at the time of the current activation with the boundary position of the area centered on the position detected at the time of the previous activation, it is complicated. There is an advantage that it is possible to easily judge whether or not the area is outside the area by subtracting the latitude and longitude on the map without performing any arithmetic processing.

Also, areas 119 and 1 shown in FIG.
20 can be formed into a shape other than a circle or a square. For example, the area may be an elliptical or rectangular area that is long in either of the latitude and longitude directions. Further, the shape may be an ellipse or a rectangle long in the traveling direction of the mobile work machine 31.
In this case, it can be determined more accurately and quickly whether the mobile work machine 31 has escaped from the area.

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

Thus, in the case of FIG. 24, equivalently, the activation cycle T becomes shorter as the moving speed of the mobile work machine 31 becomes higher, and the display screen of the terminal 11 which is the display destination terminal has more detailed information. A moving path (a moving path with a short time interval between the displayed moving positions) is displayed. Therefore, the work is completed at a certain work site, and the mobile work machine 31
On the terminal 11 side, the situation where the user is moving to the next work site can be accurately grasped. For this reason, the work efficiency of process management and transportation management is dramatically improved. In addition, since the on / off duty ratio D of activation of the communication terminal 56 is increased as the moving speed of the mobile work machine 31 increases, accurate monitoring during movement and suppression of power consumption due to communication can be performed at the same time. Can be realized.

In the embodiment shown in FIG. 24, the start cycle T is changed according to whether or not the area 119, 120... Are sequentially set, but as shown in the graph of FIG. The moving speed V of the work machine 31 may be calculated for each start cycle T, and the start cycle T may be changed according to the magnitude of the calculated speed V. In the embodiment shown in FIG. 25, the position of the mobile work machine 31 is detected by the GPS sensor 57 every time the communication terminal 56 is activated, similarly to the embodiment of FIG.

Then, the following equation: V = (detection position at the time of current activation-detection position at the time of previous activation)
The moving speed V is calculated based on the current start cycle T.

The relationship between the moving speed V and the starting period T is shown in the graph of FIG. If the moving speed V is sufficiently low, that is, equal to or lower than the speed V1 (= 3 km / h), the starting cycle T is set to the maximum cycle T1 (= 10 minutes). The traveling speed V is changed from V1 to the cruising speed V2 (= 50) during transportation by the trailer.
km / h), the activation cycle T becomes shorter. When the moving speed V reaches the cruising speed V2, the activation cycle T is 0 (the duty ratio D is 1), that is, the communication terminal 5
6 is in a continuous activation state.

The moving speed V obtained according to the above equation
Is determined from the graph shown in FIG. 25 to determine the start cycle T.

[0279] Therefore, as the moving speed V of the mobile work machine 31 increases, the activation cycle T decreases, and the display screen of the terminal 11, which is the display destination terminal, displays a more detailed moving trajectory (each moving movement to be displayed). A movement trajectory with a short time interval between positions)
Will be displayed. For this reason, the situation where the work is completed at a certain work site and the mobile work machine 31 is moving to the next work site can be accurately grasped on the terminal 11 side. Further, at the cruising speed V2 of the transport vehicle (trailer) 35, the communication terminal 56 is continuously activated and the moving position of the mobile work machine 31 is constantly displayed. The situation in which the machine 31 is loaded and traveling can be constantly monitored on the display screen of the terminal 11. For this reason, the work efficiency of process management and transportation management is dramatically improved. In addition, since the on / off duty ratio D of activation of the communication terminal 56 is increased as the moving speed of the mobile work machine 31 increases, accurate monitoring during movement and suppression of power consumption due to communication can be performed at the same time. Can be realized.

In the above-described embodiment, the communication terminal 56 is activated intermittently at the predetermined cycle T. However, the communication terminal 56 may be activated intermittently every time a specific time comes. Good.

For example, it is possible to start the communication terminal 56 at a specific time when communication between the communication satellite 9 and the mobile work machine 31 is performed well. This specific time corresponds to the position (altitude) of the communication satellite 9.

FIG. 13 (a) shows the positional relationship between the communication satellite 9 and the mobile work machine 31. In a communication path (wireless communication line 5) between the communication satellite 9 and the mobile work machine 31, communication obstacles 123 such as mountains and buildings are interposed.

When the altitude of the communication satellite 9 is large (when the maximum elevation angle is large), communication obstacles due to the obstacle 123 are reduced and the communication state is improved. Then, when the altitude of the communication satellite 9 becomes a large time, the communication terminal 56 is activated, and communication with the communication satellite 9 is performed.

However, in order to activate the communication terminal 56, it is necessary for the mobile work machine 31 to store and store information on the flying position of the communication satellite 9.

The arrival position information of the communication satellite 9 differs every day. Therefore, when trying to store and store the flying position information for all dates in the memory of the mobile work machine 31,
Insufficient memory capacity and memory occupation are caused.

Therefore, in the present embodiment, as shown in FIG. 13A, the flying position information 124 of a predetermined information amount is transmitted from the communication satellite 9 to the mobile work machine 31 via the wireless communication line 5.

A clock is provided inside the communication terminal 56 of the mobile work machine 31. Then, by comparing the received flying position information 124 with the time measured by the clock, it is determined whether to activate the communication terminal 56.

FIG. 13B shows the flying position information of the communication satellite 9 on a certain date.

In FIG. 13B, “AOS” indicates the time and azimuth at which the communication satellite 9 appears on the horizon.
“L” indicates the time and azimuth when the communication satellite is at the maximum elevation angle, and “LOS” indicates the time and azimuth when the communication satellite 9 disappears on the horizon. FIG. 13C shows the path of the communication satellite 9 corresponding to the enclosed portion.

In the communication terminal 56 of the mobile work machine 31, from the flying position information 124 shown in FIG. 13B, the time at which the maximum elevation angle equal to or greater than a predetermined threshold value (for example, 45 degrees) is obtained, that is, the maximum elevation angle 66 °, Time 4: 3 when 54 ゜ is obtained
At 3:16:28, a process of activating the communication terminal 56 is executed. That is, at specific times 4:33 and 16:28, the main power supply circuit of the communication terminal 56 is driven, and a signal indicating the mobile object information is transmitted to the communication satellite 9 via the wireless communication line 5.

In the flying position information 124, for example, new data is transmitted from the communication satellite 9 to the mobile work machine 31 via the wireless communication line 5 at the specified time every day.
Thereby, the content of the flying position information 124 stored in the memory of the mobile work machine 31 is updated.

As described above, according to the embodiment shown in FIG. 13, the communication terminal 56 is activated every time a specific time is reached when communication between the communication satellite 9 and the mobile work machine 31 is performed well. As a result, power can be saved, and communication between the communication satellite 9 and the mobile work machine 31 is reliably performed. Further, since the flying position information 124 is received from outside by communication, the mobile work machine 31 does not have the problem of insufficient memory capacity and memory occupation.

In the above-described embodiment, the communication terminal 56
Is started intermittently at a predetermined cycle T,
It is also possible to arbitrarily change the activation cycle T from, for example, the terminal 11 on the administrator side. In this case, as described above, the electronic mail in which the change data for changing the activation cycle T is described is transmitted from the terminal 11 to the mobile work machine 31 using the mobile work machine 31 as a mail address. Then, the change data described in the e-mail is read out at the communication terminal 56 of the mobile work machine 31 of the transmission destination, and the activation cycle T is changed according to the content of the change data.

For example, when the service meter of the mobile work machine 31 exceeds a predetermined value (when it is deteriorated), the start cycle T is shortened in order to frequently monitor the state at short intervals, and is lent to a specific user. If monitoring is not necessary (when there is no need for monitoring) or if the vehicle has been suspended for a long time (when it is clear that operation has stopped), the monitoring interval is lengthened to reduce unnecessary power consumption and communication charges Then, the start cycle T is lengthened. Note that a plurality of moving bodies that are working and traveling in a group can be simultaneously changed to the same activation cycle T.

As described above, according to the present embodiment, the terminal 11
The side can change the activation cycle T by remote control while monitoring the situation of the moving body and the surrounding situation. This eliminates the need for the worker to go out to each of the moving bodies 31, 32,... And perform the work of changing the startup cycle T, and the workload is greatly reduced.

As described above, according to the present embodiment, the moving object 3 such as a construction machine for which the engine is not operating for a long time is used.
Even if the number of terminals is 1 to 35, multiple terminals 1
, And can respond to requests from the terminals 11, 12,..., And useless power consumption can be suppressed.

This embodiment in which the power supply for communication is turned on intermittently can be applied to any communication system without being limited to the communication system shown in FIG. Any communication system that includes at least two communication stations and performs communication between the two communication stations is applicable.

By the way, in the above-described embodiment, only when the request source terminal (for example, the terminal 11) requests the mobile object (for example, the mobile work machine 31) for the mobile information, the display destination terminal is made. It is assumed that mobile object information is displayed on (for example, terminal 12).

In the embodiment described below, even if there is no request from the terminal side, if the parameter becomes a specific value inside the mobile body, the specific mobile body information is spontaneously transmitted and the specific information is transmitted to the terminal side. Is displayed.

According to this embodiment, it is possible to recognize an abnormal situation (for example, a failure or the like) occurring in a mobile unit that cannot be constantly managed and monitored on the terminal side,
It is possible to accurately grasp the state of suspension.

Now, as shown in FIG. 2, parameters inside the mobile work machine 31, for example, the starting state of the engine are detected by a predetermined sensor (for example, a sensor for detecting the voltage value of the alternator) of the sensor group 62. And As described above, the detection signal of this sensor is described in a frame signal by the electronic control controller 53 and is transmitted to the signal line 52 to be input to the communication terminal 56 via the communication controller 54. If the communication terminal 56 can monitor the on / off state of the engine, a known technique other than this method may be used.

FIG. 26 (a) shows a signal indicating the starting state of the engine, which is input to the communication terminal 56 of the mobile work machine 31. FIG. 26A shows an engine start state of the mobile work machine 31 at each time t during one day (from time 6:00 to the next 6:00), and the logic “1” level indicates that the engine is running (starting). ), And the logic “0” level corresponds to the state where the operation of the engine is stopped.

Automatic transmission from the mobile work machine 31 can be performed at the timing of each engine start, for example, as shown in FIG.

That is, as shown in FIG.
When the engine is started at 1 and a signal indicating that the engine has been started is input to the communication terminal 56, this signal is used as a trigger to generate specific moving body information, that is, for example, information on the mobile work machine 31, as shown by an arrow e. The current position is captured in the electronic mail and transmitted to the communication satellite 9 as an electronic mail. The destination mail address of this e-mail is the server terminal 21. The communication terminal 5 is operated by the power saving operation described above.
When 6 is in the sleep state, it is transmitted after the engine is started and forced start is started.

Therefore, assuming that the server terminal 21 is a terminal on the manager side, the display screen of the terminal 21 on the manager side displays successive positions each time the engine is started by the mobile work machine 31. become. Therefore, the administrator can grasp the history of the position each time the engine is started on the mobile work machine 31 on the display screen without performing the request input operation by himself, and the mobile work machine 31 that cannot be constantly managed and monitored. Can recognize the abnormal situation that occurred in
It is possible to accurately grasp the operation state and the vehicle stop state of the mobile work machine 31.

[0306] The mobile work machine 31 sends another terminal 11,
The electronic mail may be transmitted using the terminal 12... As the destination mail address.

[0307] Automatic transmission from the mobile work machine 31 is as follows.
As shown in FIG. 26 (c), it may be performed at the first engine start timing of the day.

That is, as shown in FIG.
When the engine is started in step 1, a start signal indicating that the engine has been started is input to the communication terminal 56. Here, a clock is provided inside the communication terminal 56, and it is determined whether or not this start signal is the first input signal in one day (from time 6:00 to the next time 6:00). Is determined. Only when the input start signal is determined to be the start signal input first in one day, the start signal is used as a trigger to move the mobile work machine 3 as shown by the arrow f.
The current position of No. 1 is taken into the electronic mail and transmitted to the communication satellite 9 as the electronic mail. Therefore, similarly, the history of the position of the mobile work machine 31 is displayed on the terminal on the administrator side. According to the present embodiment, the communication cost can be reduced because the interval of automatic transmission is at least every day as compared with the case of FIG.

The automatic transmission is performed only when the engine is first started in one day, but the period can be set arbitrarily. For example, the engine is started first in one week. Automatic transmission may be performed only when a call is made.

The automatic transmission from the mobile work machine 31
As shown in FIG. 26 (d), it may be performed at the timing of starting the engine in a specific time zone of the day (for example, from 18:00 to 6:00).

That is, at time 1 as shown in FIG.
When the engine is started at time t4 in the time period from 8:00 to 6:00, and a signal indicating that the engine has been started is input to the communication terminal 56, the signal is used as a trigger as indicated by an arrow i. Then, the current position of the mobile work machine 31 is captured in the e-mail and transmitted to the communication satellite 9 as an e-mail. Therefore, similarly, the history of the position of the mobile work machine 31 in the specific time zone is displayed on the terminal on the administrator side. Here, time 18:00 to 6:00
Is a time zone in which mobile work machines such as construction machines are not normally operating. Even more, it is a time zone where long-term travel is not performed. The fact that the engine has been turned on and the mobile work machine 31 has moved during this specific time zone may have caused some unusual occurrence. A history of the position of the mobile work machine 31 in a specific time zone is displayed on the terminal on the administrator side. By monitoring this display screen, it is determined that some abnormality has occurred in the mobile work machine 31. be able to.

[0312] Automatic transmission from the mobile work machine 31 is as follows.
As shown in FIG. 26 (e), it may be performed at the timing of stopping the engine due to an abnormality.

Here, as shown in FIG.
Abnormalities such as "high engine speed"
"High engine exhaust temperature", "High coolant temperature", "Low battery voltage", "Low fuel"
Is detected by a predetermined sensor of the sensor group 62. As described above, the detection signal of this sensor is described as an error code (for example, “abnormal item: low fuel amount”) in the frame signal by the electronic control controller 53 and is transmitted to the signal line 52 so that the communication controller 5
4 to the communication terminal 56. Communication terminal 5
As long as the abnormality of the vehicle body can be monitored in step 6, a known technique other than this method may be used.

When the operation of the engine is stopped at time t2 as shown in FIG. 26 (a), a stop signal indicating that the engine has been stopped is input to the communication terminal 56. Here, the error code is input to the communication terminal 56.
Then, it is determined whether the stop signal and the error code are input at the same time. If the stop signal and the error code are input at the same time, it is determined that the engine has stopped due to an abnormality (failure), and the stop signal is used as a trigger to indicate the current position of the mobile work machine 31 as shown by the arrow g. Is taken into the electronic mail and transmitted to the communication satellite 9 as the electronic mail. Therefore, similarly, the position of the mobile work machine 31 is displayed on the terminal on the administrator side.
According to the present embodiment, the position of the mobile work machine 31 is displayed on the terminal only when the abnormality is detected and the engine is stopped, so that the position at the time of occurrence of the abnormality can be accurately grasped. . Therefore, the abnormality can be dealt with promptly, and damage to the mobile work machine 31 can be minimized.

Further, a specific abnormal item (severe abnormal item) among abnormal items (error codes) is set in advance, not automatically transmitted when an abnormality occurs, and this severe abnormality occurs. Automatic transmission may be performed only when the call is made.

The automatic transmission from the mobile work machine 31
As shown in FIG. 26 (f), it may be performed at the timing of starting the engine due to the elimination of the abnormality.

That is, as shown in FIG.
When the engine is started in step 3, a start signal indicating that the engine has been started is input to the communication terminal 56. Here, the error code is input to the communication terminal 56. When the serviceman or the like performs a predetermined process for the abnormality and the abnormality (failure) is resolved, the error code is transmitted to the communication terminal 5.
6 is no longer entered. The communication terminal 56 determines whether or not the engine has been started when the error code is no longer input. If the engine is started at the time when the error code is no longer input, it is determined that the engine has been started after the abnormality (failure) has been resolved, and the start signal is used as a trigger, as indicated by an arrow h. The current position of the mobile work machine 31 is captured in the e-mail, and transmitted to the communication satellite 9 as an e-mail. Therefore, similarly, the position of the mobile work machine 31 is displayed on the terminal on the administrator side. According to the present embodiment, the position of the mobile work machine 31 is displayed on the terminal only when the abnormality is resolved and the engine is started, so that the position at the time when the abnormality is appropriately treated is accurately grasped. be able to.

At a specific time (for example, time 23:00) from the mobile work machine 31, a specific moving body information, for example, an operation map up to time 23:00 of the day (the engine runs from what time what time to what time what minute). Memory to show you were there)
May be automatically transmitted. As a result, a daily operation map is displayed on the display screen of the terminal as shown in FIG.

[0319] The mobile work machine 31 may automatically transmit specific mobile unit information at a specific time every several days (for example, at 23:00 every three days).

At a specific time on a specific day of the week (eg, 23:00 on a Saturday) from the mobile work machine 31,
Specific mobile object information may be automatically transmitted.

As described above, specific mobile object information is transmitted at a specific time, so that specific mobile object information of the mobile work machine 31 can be periodically acquired from the display screen of the terminal.

When the cumulative value of the operating time of the mobile work machine 31 becomes a specific cumulative value of the operating time, for example, the absolute value of the service meter becomes 100 hours, 300 hours, 500 hours.
When the time is reached, specific moving object information (for example, “service meter”, “vehicle alarm 1” (error code 1),
“Body alarm 2” (error code 2), “battery voltage”, “engine water temperature”, “engine speed”, “pump pressure”, “oil amount” may be automatically transmitted.

As described above, specific moving body information is transmitted when a specific accumulated operating time value is reached, so that preliminary information for performing a statutory periodic inspection can be obtained on the display screen of the terminal. . In addition, since automatic transmission is performed in accordance with the operating time transition (load), useless communication is prevented from being performed during the suspension period, and communication cost can be reduced.

Each time the cumulative value of the operation time of the mobile work machine 31 increases by a specific amount, for example, every time the increase value of the service meter elapses 100 hours from the last automatic transmission (or 500 hours elapse). Each), specific mobile object information (for example, “service meter”, “body alarm 1”)
(Error code 1), “Body alarm 2” (Error code 2), “Battery voltage”, “Engine water temperature”, “Engine speed”, “Pump pressure”, “Oil amount”) may be transmitted automatically. . The setting of the service meter increment can be set in accordance with the patrol time by the service car 34.

[0325] As described above, specific moving body information is transmitted every time the cumulative operating time increases by a specific amount, so that preliminary information for performing a statutory periodic inspection is obtained on the display screen of the terminal. be able to. When the information is displayed on the terminal on the administrator side, the traveling instruction to the service car 34 can be easily performed. When displayed on the terminal of the serviceman, the mobile work machine requiring the service can be easily specified, and the service by the service car 34 can be quickly performed. In addition, since automatic transmission is performed in accordance with the operating time transition (load), useless communication is prevented from being performed during the suspension period, and communication cost can be reduced.

The above embodiment can be variously modified. Hereinafter, FIGS. 9, 10, 11, 12, and 14 will be described.

[0327] The automatic transmission may be performed when the position of the mobile work machine 31 changes.

The position of the mobile work machine 31 is detected by the GPS sensor 57 as shown in FIG. The detection result of the GPS sensor 57 is input to the communication controller 54. When the communication controller 54 determines that the position of the mobile work machine 31 has changed, the changed position information is sent to the communication terminal 56 as transmission data. Then, an electronic mail in which the position information is described is automatically transmitted from the communication terminal 56 via the satellite communication antenna 58.

As described above, since the position information is transmitted each time the position of the mobile work machine 31 changes, the movement history of the mobile work machine 31 can be obtained on the display screen of the terminal.

The automatic transmission may be performed when the mobile work machine 31 deviates from the specific set range 129 as shown in FIG.

The position of the mobile work machine 31 is detected by the GPS sensor 57 as shown in FIG. The detection result of the GPS sensor 57 is input to the communication controller 54. The communication controller 54 stores position information of the work site. The setting range 129 of the work site is a radius S (k
m). Therefore, the detected position of the mobile work machine 31 is compared with the boundary position of the setting range 129, and it is determined whether the mobile work machine 31 has deviated from the set range 129. The mobile work machine 31 is positioned at the boundary position J of the setting range 129.
Is reached, the position information of the mobile work machine 31 at that time is transmitted to the communication terminal 56 as transmission data. Then, an electronic mail in which the position information is described is automatically transmitted from the communication terminal 56 via the satellite communication antenna 58.

As described above, when the mobile work machine 31 is in the setting range 1
Since the position information is transmitted at the time when the vehicle deviates from the position 29 (when the position exceeds the set position), it is easy to monitor whether or not the mobile work machine 31 is operating in the work site on the display screen of the terminal. Can be done. Setting range 129
Is not limited to the fixed range of the work site,
The range may be a range centered on the position where the mobile work machine 31 existed in the past. That is, the setting range may be updated as time passes.

The shape of the setting range 129 is not limited to a circle, but may be an ellipse, a square, a rectangle, an ellipse having a traveling direction of the mobile work machine 31 as a longitudinal direction, a rectangle, or the like.
It can be of any shape.

The setting range 129 shown in FIG.
A range corresponding to the normal range 117 shown in FIG.

The automatic transmission may be performed when the amount of change in the moving position of the mobile work machine 31 exceeds the set value as shown in FIG.

The position of the mobile work machine 31 is detected by the GPS sensor 57 as shown in FIG. The detection result of the GPS sensor 57 is input to the communication controller 54 at a constant sampling cycle. The communication controller 54 calculates the moving speed V of the mobile work machine 31 based on the difference between the position detected previously and the position detected this time, and the sampling time. Therefore, the moving speed V of the mobile work machine 31
Is compared with the set value V2 (FIG. 25) to determine whether or not the speed V of the mobile work machine 31 has exceeded the set value V2. When the speed V of the mobile work machine 31 exceeds the set value V2, the position information of the mobile work machine 31 at that time is transmitted to the communication terminal 56 as transmission data. Then, an electronic mail in which the position information is described is automatically transmitted from the communication terminal 56 via the satellite communication antenna 58.

As described above, the position information is transmitted when the speed V of the mobile work machine 31 exceeds the set value V2.
It is possible to easily monitor the moving state of the mobile work machine 31 on the display screen on the terminal side. That is, the mobile work machine 31 such as a construction machine travels at an extremely low speed.
Therefore, if the set value V2 is set to a high speed at which the mobile work machine 31 cannot normally run on its own, for example, a speed at which the trailer 35 cruises on an expressway, the speed V of the mobile work machine 31 becomes equal to the set value V2. If it exceeds, it can be determined that the vehicle is being transported by the trailer 35. In addition, when the vehicle is being transported by a trailer under normal circumstances when transportation is not performed, it can be recognized that an abnormal situation has occurred, and appropriate measures can be taken promptly.

[0338] Automatic transmission may be performed when the service car 34 enters the specific set ranges 125 and 126 as shown in FIG.

The position of the service car 34 is detected by the GPS sensor 57 as shown in FIG. The detection result of the GPS sensor 57 is input to the communication controller 54. The communication controller 54 includes the mobile work machine 31 to be serviced.
The location information of the destination 126 and the no-entry area 125 where the information exists is stored. The setting range 126 of this destination
Is a circle of a predetermined radius centered on the position of the mobile work machine 31. The intrusion prohibited area 125 is, for example, a road restricted by heavy rain or an area with bad ground.

The detected position of the service car 34 is compared with the boundary position between the set ranges 125 and 126 to determine whether the service car 34 has entered the set range 125 or 126. The service car 34 travels along the route 127 or 128 to set the range 125 or 12
When the vehicle reaches the boundary position H or I, the position information of the service car 34 at that time is transmitted to the communication terminal 56 as transmission data. Then, an electronic mail in which the position information is described is automatically transmitted from the communication terminal 56 via the satellite communication antenna 58.

As described above, the service car 34 has the setting range 1
Since the position information is transmitted at the time of intruding into 25 or 126 (when exceeding the set position), whether or not the service car 34 has arrived at the destination on the display screen of the terminal, or in the intrusion prohibited area It is possible to easily monitor whether or not the intrusion has occurred. That is, the administrator can recognize from the display screen of the terminal that the service car 34 has arrived at the destination 126 and starts the service, and that the service car 34 has entered the intrusion prohibited area 125 and is in a dangerous state. Can be recognized. Therefore, as described above, appropriate work instruction data (messages “return as soon as possible” and “avoid intrusion prohibited area”) can be transmitted from the terminal on the administrator side to the service car 34 (see FIG. 4). ).

The shape of the destination setting range 126 is not limited to a circle, but may be an ellipse, a square, a rectangle, or the like.
It can be of any shape.

The setting ranges 125 and 126 shown in FIG.
May be a range corresponding to the abnormal range 118 shown in FIG.

The automatic transmission may be performed when the amount of data to be transmitted matches the set value or exceeds the set value, as shown in FIG.

In a communication system employing a pay-as-you-go system, as shown in FIG. 11A, the communication fee to be paid at one time is a fixed monthly charge up to a predetermined data amount Do.
When the data amount D exceeds the set value D0, it is necessary to pay an additional charge for the excess data amount.

Therefore, specific mobile unit information to be automatically transmitted from the mobile work machine 31 is collected and stored in the communication controller 54. The communication controller 54 compares the stored data amount D with a set value (80% of D0).
Then, as shown in FIG. 11B, the accumulated data amount D
At the time when the value matches the set value (80% of D0), the stored mobile unit information is transmitted to the communication terminal 56 as transmission data. Then, a satellite communication antenna 58 is transmitted from the communication terminal 56.
An e-mail in which the mobile object information is described is automatically transmitted via.

Since the mobile unit information is transmitted when the data amount D to be automatically transmitted matches (or exceeds) the set value, the maximum amount of mobile unit information within the fixed amount is displayed on the terminal side. It can be displayed on the screen.

The automatic transmission may be performed when the fuel amount matches the set value or falls below the set value as shown in FIG.

The fuel amount is detected by the sensor group 62 in the mobile work machine 31 and is sequentially transmitted to the communication controller 54. The communication controller 54 compares the detected fuel amount with the set value. Then, when the detected fuel amount matches the set value as shown in FIG.
The mobile body information (“position”, “fuel amount”) is transmitted to the communication terminal 56 as transmission data. Then, an electronic mail in which the mobile body information is described is automatically transmitted from the communication terminal 56 via the satellite communication antenna 58.

When the fuel amount matches the set value (or becomes equal to or less than the set value), the mobile unit information is transmitted, and it is time to refuel from the display screen on the terminal side. You can recognize that. Therefore, in the same manner as in FIGS. 3 and 4, appropriate work instruction data (message “refuel”) can be transmitted from the terminal on the administrator side to the service car 34 that performs the refueling patrol service.

The automatic transmission may be performed when the voltage of the battery 63 matches the set value or falls below the set value as shown in FIG.

The sensor group 62 in the mobile work machine 31 detects the voltage value of the battery 63, and the communication controller 54
Are sequentially transmitted to The communication controller 54 compares the detected battery voltage with a set value. Then, when the detected battery voltage matches the set value as shown in FIG. 12B, the mobile object information (“position”,
“Battery voltage”) is transmitted to the communication terminal 56 as transmission data. Then, an electronic mail in which the mobile body information is described is automatically transmitted from the communication terminal 56 via the satellite communication antenna 58.

As described above, when the voltage of the battery 63 matches the set value (or becomes equal to or less than the set value), the mobile object information is transmitted. It is possible to recognize that it is time to carry out maintenance or inspection. Therefore, in the same manner as in FIGS. 3 and 4, appropriate work instruction data (message “check battery”) can be transmitted to the service car 34 from the terminal on the administrator side. Also, by recognizing on the display screen of the terminal that the battery 63 is in a state of being almost discharged, a request to turn on the sleep function is transmitted thereafter, and communication with the mobile work machine 31 is performed only intermittently. It is set so that no further discharge can occur.

If the mobile unit information automatically transmitted last time and the mobile unit information to be automatically transmitted this time have the same content,
It is also possible to implement such that automatic transmission is not performed.

As shown in FIG. 2, abnormalities occurring in the mobile work machine 31, such as "high engine speed", "high engine exhaust temperature", "high cooling water temperature",
Abnormalities such as “low battery voltage” and “low fuel amount” are detected by a predetermined sensor of the sensor group 62. As described above, the detection signal of this sensor is described as an error code (for example, “abnormal item: low fuel amount”) in the frame signal by the electronic control controller 53 and is transmitted to the signal line 52 to be sequentially input to the communication controller 54. Is done.

In the communication controller 54, the error code transmitted automatically last time is compared with the currently input error code. Then, only when the previously transmitted error code and the currently input error code have different contents, the currently input error code is transmitted to the communication terminal 56 as transmission data. Then, an electronic mail in which the mobile body information is described is automatically transmitted from the communication terminal 56 via the satellite communication antenna 58.

As described above, the automatic transmission is performed only when the error code transmitted automatically last time and the error code to be automatically transmitted this time are different, and the error code transmitted last time and the automatic transmission this time are performed. Since the automatic transmission is not performed when the error code to be transmitted has the same content, it is possible to avoid waste of transmitting the same information a plurality of times. The same applies to the case where mobile body information other than the error code is automatically transmitted.

[0358] In the above-described embodiment, when a parameter has a specific value inside the moving object, the specific moving object information is spontaneously transmitted.
(Storage data such as data amount D, sensor detection data such as battery voltage), the contents of “specific value” and “specific moving object information” are stored in, for example, a terminal (server terminal 2) on the administrator side.
It is also possible to arbitrarily change from the terminal 11).
In this case, as described above, from the terminal, an e-mail in which change data for changing the above parameters and the like are described,
The mobile work machine 31 is transmitted to the mobile work machine 31 as a mail address. And the mobile work machine 3 of the transmission destination
The change data described in the e-mail is read from one communication terminal 56, and the parameters and the like are changed according to the contents of the change data.

For example, when the service meter of the mobile work machine 31 exceeds a predetermined value (when it is deteriorated), the monitoring interval becomes short, and when it is lent to a specific user (there is no need for monitoring). ) Or if the vehicle has been suspended for a long period of time (when it is clear that the operation has stopped), the “parameter” and “specification” are set so that the monitoring interval becomes longer and unnecessary power consumption and communication charges are reduced. Of the "value" and "specific mobile object information" are changed. Note that a plurality of moving bodies that are working and traveling in a group can be changed to the same content at the same time. For example, "specific moving object information" can be reduced to only important monitoring items.

As described above, according to this embodiment, it is possible to change the timing and content of automatic transmission by remote control while monitoring the situation of the moving object and the surrounding situation on the terminal side. This eliminates the need for the worker to perform the outgoing change work to each of the moving bodies 31, 32,..., And the work load is greatly reduced.

If the mobile unit information to be transmitted by automatic transmission is the position of the mobile unit, the latitude and longitude on the map may be transmitted as the position information, and the relative position with respect to a specific reference is transmitted as the position information. May be.

Instead of automatically transmitting the voltage value of the battery 63 as mobile object information, the amount of change in the voltage of the battery 63 may be transmitted automatically.

As the mobile unit information, the operating load information, the work amount, and the fuel consumption amount may be automatically transmitted.

As described above, according to this embodiment, even if the terminal does not perform the request input operation on the terminal itself,
It is possible to grasp specific moving object information when a specific parameter reaches a specific value. Therefore, abnormal situations (for example, failures) that occur in mobiles that cannot be constantly managed and monitored
Can be recognized, and the operating state and the rest state of the moving object can be accurately grasped.

This embodiment of automatic transmission can be applied to any communication system without being limited to the communication system shown in FIG. Any communication system that includes at least two communication stations and performs communication between the two communication stations is applicable.

The information to be displayed on the terminals 11 and 12 is enormous. Therefore, an embodiment will be described in which only important information is set in advance from a vast amount of information, and only this important information is collectively displayed on a specific display screen. As a result, the administrator can quickly determine and deal with an abnormal situation.

In the following embodiments, the mobile work machine 31 will be described as a representative. The terminal 11 is connected to the mobile work machine 31.
It is assumed that this is a terminal on the administrator side that manages. It is also assumed that the server of the terminal 11 is the server terminal 21.

Although not shown in FIG. 2, the mobile work machine 3
A start lock circuit is incorporated in one vehicle body 50. This start lock circuit is constituted by a relay or the like and is interposed between the key switch 64 (FIG. 21) and the fuel injection device.

When the start lock setting command is output from the communication controller 54, the relay of the start lock circuit is energized to enter the start lock setting state. That is, even if the key switch 64 is turned on, fuel is not injected and the engine cannot be started. On the other hand, when a start lock release command is output from the communication controller 54,
The relay of the start lock circuit is deenergized and the start lock is released. That is, when the key switch 64 is turned on, fuel is injected and the engine is started.

The vehicle 31 may move by itself or may move by being loaded on a carrier such as a trailer. Here, it is assumed that the vehicle is loaded on a trailer and moved. Note that the following processing can be similarly applied when the vehicle 31 moves by itself.

In the server terminal 21, a display screen of a homepage called a "notification screen" shown in FIG. 34 is created.
This "notification screen" is set on the first page of the homepage. On the “notification screen”, only the following important information is displayed collectively.

A) Information that the vehicle 31 is out of the set range b) Information that the engine of the vehicle 31 has been started outside the fixed time c) Information that the battery voltage of the vehicle 31 has dropped d) Setting of the start lock Or information that the release has been performed e) information that communication between the vehicle 31 and the server terminal 21 has been interrupted f) information that a request for the vehicle 31 has not been achieved (for example, when a start lock setting command is issued. Regardless, information that the start lock is not set in the vehicle 31) That is, the automatic transmission is performed from the vehicle 31 side and the server terminal 2
When receiving the automatically transmitted mobile body information in step 1, the server terminal 21 determines whether or not the mobile body information should be displayed on the "notification screen" of the homepage.

Now, outside the fixed time on the vehicle 31 side (time 17: 0)
When the engine is started at 0-8: 00), information that "the engine of the vehicle 31 has been started" is automatically transmitted to the server terminal 21 by e-mail. Since this moving body information is the specific information of b), it is determined that it should be displayed on the “notification screen”, and the display content of the “notification screen” is updated.

Therefore, the terminal 11 managing the vehicle 31
When the WWW browser is activated, the homepage data is read from the server terminal 21 via the WWW browser and displayed on the display screen of the display device of the terminal 11.

FIG. 34 shows the first page of the home page displayed on the display device of the terminal 11, that is, the screen at the time of startup.

As shown in FIG. 34, the content of “the vehicle has started the engine outside the fixed time” is “occurrence time”,
The information is displayed together with the contents specifying the “maker”, “model”, “model number”, “machine number”, and “ID” of the vehicle 31. From this display screen, the manager can know that the vehicle 31 has "started the engine outside the fixed time", and can take quick and accurate measures against abnormal situations such as mischief.

The administrator can set the vehicle 31 to the start lock setting state by remote control. This is executed by setting the display screen of the terminal 11 to the “engine restart prohibition setting screen” and clicking the “engine restart prohibition” button. As a result, an e-mail indicating that the vehicle 31 is to be set to the start lock state is transmitted from the terminal 11 to the vehicle 31.

[0378] On the vehicle 31 side, when data indicating that the start lock is set is received by the communication terminal 56 via the satellite communication antenna 58, the data is transmitted to the communication controller 5
4 is taken in. Thereby, the communication controller 54
Outputs a start lock setting command to the start lock circuit. For this reason, the relay of the start lock circuit is energized to set the start lock. That is, even if the key switch 64 is turned on, fuel is not injected and the engine of the vehicle 31 is not restarted.

The vehicle 31 determines whether or not the start lock has been set. When it is determined that the start lock has been set on the vehicle 31 side, information that “the vehicle 31 has been remotely set to start lock” is automatically transmitted to the server terminal 21 by e-mail. Since this mobile object information is the specific information of d), the server terminal 21 determines that it should be displayed on the “notification screen”, and the display content of the “notification screen” is updated.

[0380] Therefore, the display screen of the terminal 11 is displayed as shown in FIG.
As shown in the figure, the contents "locked remotely" are displayed together with the contents of "time of occurrence", "manufacturer", "model", "model number", "machine number", and "ID" of the vehicle 31. Is done. From this display screen, the administrator can view the vehicle 31
Can be confirmed as "remote start locked".

[0381] The server terminal 21 stores the fact that an e-mail has been sent to the vehicle 31 to set the vehicle in the start lock state. Therefore, even if a predetermined time has passed since the e-mail was transmitted to the vehicle 31 side, if the information that "the start lock was set remotely" was not returned by e-mail from the vehicle 31, the server terminal 21
"Even though the start lock setting command was issued, the vehicle 31
Is not set to start lock. " That is, it is determined that “the request for the vehicle 31 has not been achieved”. This may be caused by a malfunction of the starting lock circuit of the vehicle 31 on the vehicle 31 side or by the vehicle 31 and the server terminal 21.
There are two possible causes for the poor communication status between the two. Since the mobile unit information or the communication state information is the specific information of the above f), the server terminal 21 displays the “notification screen”
And the display content of the "notification screen" is updated.

Therefore, the display screen of the terminal 11 is
As shown in the figure, the content "lock confirmation has not been received from the vehicle" specifies "occurrence time", "maker", "model", "model number", "machine number", and "ID" of the vehicle 31. Displayed with the contents. From this display screen, the administrator can know that "the lock has not been confirmed" in the vehicle 31. And it is possible to take quick and accurate measures against this abnormal situation.

[0383] The administrator can put the vehicle 31 into the start lock release state by remote control. This is executed by setting the display screen of the terminal 11 to the “engine restart release screen” and clicking the “engine restart release” button. As a result, an e-mail indicating that the vehicle 31 is to be in the starting lock release state is transmitted from the terminal 11 to the vehicle 31 side.

On the vehicle 31 side, when data indicating that the starting lock is released is received by the communication terminal 56 via the satellite communication antenna 58, the data is transmitted to the communication controller 5
4 is taken in. Thereby, the communication controller 54
, A start lock release command is output to the start lock circuit. For this reason, the relay of the start lock circuit is deenergized and the start lock is released. That is, by turning on the key switch 64, fuel is injected and the engine of the vehicle 31 can be restarted.

The vehicle 31 determines whether or not the starting lock has been released. When it is determined that the start lock has been released on the vehicle 31 side, information that "the vehicle 31 has been remotely released from the start lock" is automatically transmitted to the server terminal 21 by e-mail. Since this mobile object information is the specific information of d), the server terminal 21 determines that it should be displayed on the “notification screen”, and the display content of the “notification screen” is updated.

For this reason, the display screen of the terminal 11 shows the contents of “occurrence time”, “manufacturer”, “model”, “model number”,
The information is displayed together with the content specifying the “machine number” and “ID”. From this display screen, the administrator can confirm that the vehicle 31 is "remotely released from the start lock".

[0387] The server terminal 21 stores the fact that the electronic mail to the effect that the starting lock is released is transmitted to the vehicle 31. Therefore, even if a predetermined time has passed since the e-mail was transmitted to the vehicle 31 side, if the information that "the start lock was remotely released" was not returned from the vehicle 31 by e-mail, the server terminal 21
"Even though the start lock release command was issued, the vehicle 31
And the start lock has not been released. " That is, it is determined that “the request for the vehicle 31 has not been achieved”. This may be caused by a malfunction of the starting lock circuit of the vehicle 31 on the vehicle 31 side or by the vehicle 31 and the server terminal 21.
There are two possible causes for the poor communication status between the two. Since the mobile unit information or the communication state information is the specific information of the above f), the server terminal 21 displays the “notification screen”
And the display content of the "notification screen" is updated.

[0388] Therefore, the display screen of the terminal 11 indicates that "the confirmation of unlocking has not been received from the vehicle" is "time of occurrence", "maker", "model", "model number", "machine" of the vehicle 31. No. "and" ID "are displayed. From this display screen, the administrator can know that "the lock release has not been confirmed" in the vehicle 31. And it is possible to take quick and accurate measures against this abnormal situation.

[0389] If the starting device operates even though the vehicle 31 is once locked to the start, the vehicle 31
A message to that effect may be sent automatically. That is, information indicating that "the vehicle has started even though the start lock has been set remotely" may be displayed on the "notification screen" in FIG.

[0390] Now, automatic transmission from the vehicle 31 is carried out every day.
It is assumed that the process is performed every 3:00. As shown in FIG. 30, the content of the operation map is updated every day, and at 23:00 every day, the updated operation map is automatically transmitted from the vehicle 31. Therefore, a state in which the transmission from the vehicle 31 has not continued for a predetermined time, for example, 36 hours or more, means that an abnormality has occurred in the communication state. This “36 hours” is a time obtained by adding a normal operation time (12 hours: 8:00 to 8:00 PM) to the next day (24 hours).

[0391] The server terminal 21 stores the time when the e-mail was sent from the vehicle 31 to the server terminal 21 last time. Therefore, if the state of unsending continues for a predetermined time (36 hours) since the last time the e-mail was transmitted from the vehicle 31 side, the server terminal 21 determines that “communication with the vehicle 31 has not been performed for 36 hours or more”. You. That is, the vehicle 31
It is determined that communication between the server and the server terminal 21 is interrupted. This may be caused by both the cause of the vehicle 31 such as a failure or breakage of the communication device of the vehicle 31 or the cause of the poor communication state between the vehicle 31 and the server terminal 21.
Since the mobile unit information or the communication state information is the specific information of the above e), the server terminal 21 determines that it should be displayed on the “notification screen”, and the display content of the “notification screen” is updated.

Therefore, the display screen of the terminal 11 is
As shown in the figure, the content "communication with the vehicle for more than 36 hours" specifies the "occurrence time", "maker", "model", "model number", "machine number", and "ID" of the vehicle 31. Displayed with the contents. From this display screen, the administrator can know that “communication has been interrupted” with the vehicle 31. And it is possible to take quick and accurate measures against this abnormal situation.

In this embodiment, it is determined that the communication with the vehicle 31 has been interrupted based on the fact that there is no next automatic transmission even if a predetermined time has elapsed since the previous automatic transmission. However, it is determined that the communication with the vehicle 31 has been interrupted because there is no reply from the vehicle 31 even after a predetermined time has passed since the terminal 11, 12,... You may.

As described above, the battery 6 of the vehicle 31
3 are detected by the sensor group 62 and the communication controller 5
4 is input. In the communication controller 54, the battery 6
It is determined whether or not the voltage of No. 3 continuously drops (for example, 1 minute or more) below a predetermined level (for example, 23 V). A decrease in the voltage of the battery 63 not only makes it difficult to start the vehicle 31 but also impairs the on-board communication function, and is a serious abnormal situation. When the start lock circuit of the vehicle 31 is operated, power is consumed by the relay of the start lock circuit, so that the voltage of the battery 63 tends to decrease.

If it is determined on the vehicle 31 side that the voltage of battery 63 has continuously decreased (for example, 1 minute or more) to a predetermined level (for example, 23 V) or less, the server terminal 21 transmits the message “Battery of vehicle 31”. 63 is automatically transmitted by e-mail.
Since this mobile object information is the specific information of c), the server terminal 21 determines that it should be displayed on the “notification screen”, and the display content of the “notification screen” is updated.

[0396] For this reason, the display screen of the terminal 11 indicates "battery voltage is low" as "occurrence time",
The information is displayed together with the contents specifying the “maker”, “model”, “model number”, “machine number”, and “ID” of the vehicle 31. From this display screen, the administrator can know that “the voltage of the battery 63 has dropped” of the vehicle 31. And it is possible to take quick and accurate measures against this abnormal situation.

As described above with reference to FIGS. 9 and 10, the automatic transmission is performed when the position of the vehicle 31 changes.

That is, as shown in FIG. 10, when the vehicle 31 deviates from the specific set range 129, the automatic transmission is performed. The specific setting range 129 is set to, for example, a management area of the vehicle 31 (for example, “Tokyo”) and a range in which the vehicle 31 can move (for example, “Japan”). If it is out of the setting range, it can be determined that an abnormal situation has occurred.

When the vehicle 31 determines that the vehicle 31 has deviated from the specific set range 129, information that "the vehicle 31 is out of range" is automatically transmitted to the server terminal 21 by e-mail. Since this moving object information is the specific information of a), the server terminal 21 determines that it should be displayed on the “notification screen”, and the display content of the “notification screen” is updated.

[0400] For this reason, the display screen of the terminal 11 indicates "occurrence time", "maker", "model", "model number", "machine number", "ID" of the vehicle 31 on the display screen of the terminal 11.
Is displayed together with the content specifying From this display screen, the administrator can know that the vehicle 31 is "out of range". And it is possible to take quick and accurate measures against this abnormal situation.

[0401] When the vehicle 31 deviates from the specific setting range 129, an automatic call is made, and the information "vehicle is out of range" is displayed on the "notification screen". A call may be automatically transmitted when the vehicle enters, and information “vehicle is within range” may be displayed on the “notification screen”. The specific setting range 129 in this case is the vehicle 3
1 is set in an area that does not normally enter.

The “notification screen” of FIG.
Not only that, but also the other terminals 12 and the like are displayed on the display screen similarly. As a result, the “notification screen” of FIG. 34 is also displayed on the terminal 12, and important information generated up to the previous day can be easily confirmed.

Also, the display of the “notification screen” of FIG. 34 is allowed only on the display screen of the management terminal 11 that manages the vehicle 31, and the “notification screen” is not displayed on the display screens of the other terminals 12 and the like. It is possible. This is, for example, FIG.
The display of the “notification screen” of No. 4 can be realized by using a condition of inputting a specific ID number and a specific password (a number corresponding to the terminal 11).

In this embodiment, the “notification screen” shown in FIG.
Is not limited to the information shown in a) to f).

[0405] For example, information that the rental period of the vehicle 31 to the customer is approaching the end may be displayed on the "notification screen". In the vehicle 31, it is possible to detect that the rental time is approaching the end based on the value of the service meter, or that the vehicle 31 is approaching the end of the rental period by using a clock provided inside the communication terminal 56.

[0406] When the vehicle 31 has traveled a predetermined distance or more, information may be automatically transmitted from the vehicle 31 and information that "the vehicle has traveled a predetermined distance" may be displayed on the "notification screen". This predetermined distance is set, for example, to a distance at which the vehicle 31 is not considered to normally move.

[0407] When an error code is input to the communication terminal 56 of the vehicle 31, an automatic transmission may be made from the vehicle 31 side, and information that an error has occurred may be displayed on the "notification screen". In addition, the content of the error code to be displayed on the “notification screen” can be limited to a specific abnormal item (severe abnormal item). Further, the display items of the “notification screen” in FIG. 34 may be different for each vehicle 31, 32,. For example, for the vehicle 31, only the display item of a) is
For item 2, only the display item of b) can be displayed on the “notification screen”.

[0408] In this embodiment, the "notification screen" is displayed on the terminal 11 fixed at one place, but the content of the "notification screen" may be displayed on a portable terminal.

[0409] For example, the contents of the "notification screen" can be displayed on a portable telephone equipped with a WWW browser.

In this case, the packet communication network of the portable telephone and the Internet 2 are connected by a gateway. Then, the gateway converts between the protocol on the packet communication network and the TCP / IP protocol on the Internet 2, and the contents of the home page on the Internet 2 are displayed on the display screen of the mobile phone. Every time the “notification screen” is newly updated in the server terminal 21, a sound “new information has arrived” is generated in the mobile phone. As a result, the content of the newly updated “notification screen” is displayed on the display screen of the mobile phone. Note that the display items of the “notification screen” to be displayed on the mobile phone may be limited to specific display items from a) to f). For example, only the information b) that "the engine of the vehicle 31 was started outside the fixed time" can be displayed on the display screen of the mobile phone. Thus, even when the manager is away from the terminal 11, it is possible to obtain in real time information that requires urgent information about the vehicle 31 from the display screen of the mobile phone.

[0411] Construction machines are expensive and are often rented. Construction equipment is rented under a group rental system. Since there are various types of construction machines (small hydraulic excavators, medium-sized hydraulic excavators, large hydraulic excavators, etc.), this is a system in which these various types of construction machines are shared by multiple sales offices. . For this reason, when a customer requests a rental of a specific model at a certain sales office and there is no construction machine of the corresponding model, the other offices can provide the construction machine of the specific model and provide it. You never miss a chance.

[0412] In order to respond to a customer's rental request, it is necessary to surely manage the entrance and exit of construction machines at each business office. Next, an embodiment for managing storage and retrieval will be described.

FIG. 35 shows a configuration example of the embodiment.
FIG. 35 shows the business offices 130, 131, 132 existing in an area 135 called "Tokyo", for example. 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”. Reference numerals 133 and 134 denote customer work sites. The sales offices 130 to 132 manage the vehicles 31 and 32. Actually, sales offices, work sites, vehicles (mobile work machines)
Have been omitted for convenience of explanation.

13 out of the sales offices 130, 131 and 132
1 is the head office, and 130 and 132 are the branches. Headquarters 131
Manages the vehicles 31 and 32 collectively. Headquarters 131
Is provided with a terminal 11. Branches 130 and 13
2, a terminal equivalent to the terminal 11 may be provided.

The positions of the business offices 130, 131, and 132 are respectively represented by P (Px, PY) and Q (Qx,
QY) and R (Rx, RY). Each work site 1
The positions of 33 and 134 are respectively Z (Z) in the XY coordinate system.
x, ZY) and W (Wx, WY). Note that the position may be represented by a latitude and longitude on the earth so as to conform to a map on the GPS.

[0416] For each of the sales offices 130, 131, and 132, a parking area is set around the points P, Q, and R. For example, the branch 130 has a storage area 13 centered on the point P.
0a is set. Further, a delivery area 130b centering on the point P is set. The storage area 130b is larger than the storage area 130a, and has a hysteresis of ΔX between the boundary of the storage area 130b and the boundary of the storage area 130a.

Similarly, the main store 131 has a storage area 131a and a storage area 131b centered on the point Q, and the main store 132 has a storage area 132 centered on the point R.
a, a delivery area 132b is set. The size of the entry / exit area is determined in consideration of the error of the GPS measurement device, the size of the business office, and the like. For example, the entry / exit area has a vertical width and a horizontal width of several hundred meters each.

Also, for each work site 133, 134, a work area 133, 134 is set around the points Z, W.

[0419] The communication controller 54 of the vehicle 31 stores the position information of the entrance / exit area of each of the business offices 130, 131 and 132 and the position information of the work area of the work sites 133 and 134. Similarly, the communication controller 54 of the vehicle 32 stores the same position information.

In order to start communication by newly installing the communication terminal 56 on the vehicles 31 and 32, it is necessary to perform a communication application procedure and confirm receipt of the application at the server terminal 21 that manages communication. . In the present embodiment, this communication application procedure can be performed on the screen of the terminal 11.

[0421] That is, after the communication terminal 56 is mounted on the vehicles 31 and 32, an input operation of a communication application is performed from the display screen of the terminal 11. As a result, a communication connection is confirmed between the server terminal 21 and the communication terminals 56 of the vehicles 31, 32. At the same time, the server terminal 21 transmits the position information of the sales offices 130, 131, and 132 and the position information of the work sites 133 and 134 to the vehicles 31 and 32. As a result, the communication controller 54 of the vehicles 31 and 32 stores the position information of the entrance and exit areas of the business offices 130, 131 and 132 and the position information of the work areas of the work sites 133 and 134. When the communication connection is confirmed, the fact that the communication application of the vehicles 31 and 32 has been received is displayed on the display screen of the terminal 11. After confirming receipt of this application at terminal 11, vehicle 3
Communication with the first and the second 32 is enabled.

[0422] The operation when the vehicle 31 leaves the vehicle on behalf of the vehicle 31 will be described.

As described with reference to FIGS. 9 and 10, the vehicle 3
The position of 1 is the GPS sensor 5 via the GPS antenna 59
7 is detected. The detection result of the GPS sensor 57 is input to the communication controller 54. In the communication controller 54, the detection position of the vehicle 31 and each of the business offices 130, 131, 1
The position of the entry / exit area is compared with the position of the entry / exit area to determine whether or not the vehicle 31 has entered / exited from the entry / exit area.

[0424] For example, it is assumed that the vehicle 31 enters the branch 130.

[0425] The vehicle 31 is in the storage area 130 of the branch 130.
It is determined whether or not the vehicle 31 has entered the branch 130 depending on whether or not the vehicle 31 has entered the inside from outside and stays within the storage area 130a for a predetermined time (for example, a few minutes). The reason that the condition that the vehicle stays in the storage area 130a for a predetermined time or more is given in consideration of a case where the vehicle simply passes through the branch 130. As a result, receiving area 1
If it is determined that the vehicle has entered the vehicle 30a, an identification code ("vehicle 31") for identifying the vehicle 31 at that time, an identification code for identifying the branch 130 ("Nishi-Tokyo store"), and an identification code for "entry". Are transmitted from the communication controller 54 to the communication terminal 56 as transmission data. Then, a satellite communication antenna 58 is transmitted from the communication terminal 56.
An e-mail in which the above-mentioned warehousing information is described is automatically transmitted to the server terminal 21 via the server. Here, it is assumed that the server terminal 21 is provided at the location of the manufacturer that manufactured the vehicles 31 and 32.

[0426] In the server terminal 21, a display screen of a home page called "entrance / exit screen" shown in Fig. 36 is created.

[0427] That is, when the automatic transmission is made from the vehicle 31 side and the server terminal 21 receives the automatically transmitted warehousing information, the server terminal 21 describes the warehousing information on the "incoming / outgoing screen" of the homepage, and the "in / out screen" Is updated.

For this reason, the terminal 11 managing the vehicle 31
When the WWW browser is activated, the homepage data is read from the server terminal 21 via the WWW browser and displayed on the display screen of the display device of the terminal 11.

FIG. 36 shows a homepage screen displayed on the display device of the terminal 11. FIG. 36 is an “entrance / exit screen” showing the entry / exit history of the vehicle 31.

As shown in FIG. 36, the content that the vehicle 31 has been stored in the Nishi Tokyo store is displayed in real time together with the “time of storage”. From this display screen, the administrator can know that the vehicle 31 has been "stored in the Nishi Tokyo store", and can reliably make arrangements with the customer.

Similarly, it is determined that the vehicle 31 has deviated from the inside of the delivery area 130b of the branch 130 to the outside and remains outside the delivery area 130b for a predetermined time (for example, two or three minutes). 31 is branch 1
It is determined that the delivery has been made from 30. At this point, vehicle 3
Information that 1 has been dispatched from the “West Tokyo” branch 130 (this is referred to as “exit information”) is automatically transmitted to the server terminal 21 by e-mail. For this reason, as shown in FIG.
1 is displayed in real time together with the "delivery time", that is, "Issued from the Nishi Tokyo store".

Here, as described above, the delivery area 130b
Is provided with a hysteresis of ΔX between the boundary line of the storage area 130a and the boundary line of the storage area 130a. For this reason, hunting when the vehicle 31 is moving near the branch 130 can be prevented.

[0433] Similarly, when it is determined that the vehicle 31 has entered the storage area 132a of the branch 132, the storage information indicating that the vehicle 31 has stored in the "South Tokyo" branch 132 at that time is sent to the server terminal 21 by e-mail. Automatically sent to. For this reason, as shown in FIG. 36, on the “entry / exit screen” of the display device of the terminal 11, the content that the vehicle 31 has been entered into the South Tokyo store is displayed in real time together with the “entry time”.

Further, when it is determined that the vehicle 31 has left the exit area 132b of the branch 132, the vehicle 31
Is automatically sent to the server terminal 21 by e-mail. For this reason, as shown in FIG. 36, on the “entry / exit screen” of the display device of the terminal 11, the content that the vehicle 31 has left the South Tokyo store is displayed in real time together with the “exit time”.

When the vehicle 31 enters the storage area 131a of the "North Tokyo" head office 131, or when the "North Tokyo" head office 1
Similarly, when exiting from the 31 outgoing area 131b,
On the “entry / exit screen” of the display device of the terminal 11, the content that the vehicle 31 has been entered into the Kita-Tokyo store or “exited from the Kita-Tokyo store” is displayed.

[0436] Thus, as shown in FIG.
The latest history of entry / exit of 1 is displayed in real time.
A similar “entrance / exit screen” is obtained for vehicles 32 other than the vehicle 31, and the latest entry / exit history of the vehicle 31 is displayed in real time. For this reason, the management of entry and exit of the vehicles 31 and 32 can be reliably performed without error. As a result, business opportunities are not missed, and operating revenue is dramatically improved.

If it is determined that the vehicle 31 has entered the work area 133 of the rental customer, the information that the vehicle 31 has been carried into the work site 133 at that time is sent to the server terminal 21 by e-mail. Automatically sent. For this reason, the display device of the terminal 11 displays, in real time, the content that the vehicle 31 has been carried into the work site 133 together with the “carry-in time”.

If it is determined that the vehicle 31 has left the work area 133, the vehicle 31
The carry-out information indicating that the goods have been carried out of the server 33 is automatically transmitted to the server terminal 21 by electronic mail. Therefore terminal 1
On the first display device, the content that the vehicle 31 has been unloaded from the work site 133 is displayed in real time together with the “unloading time”.

Similarly, when the vehicle 31 enters or exits the work site 134,
The display device of the terminal 11 indicates that the vehicle 31 has “work site 134
Is carried in. "Or" has been carried out of the work site 134 ". Thus, the loading / unloading history of the vehicle 31 is updated.

[0440] The movement history of the vehicle 31 after leaving from each of the sales offices 130 to 132 may be displayed on the terminal 11. This is realized by automatically transmitting position information every time the vehicle 31 moves, for example, 10 km. This allows the terminal 11
, The movement history and the current position of the vehicle 31 can be confirmed.

The current position of the vehicle 31 and the work site 133,
By comparing 134 known positions Z, W,
Whether or not the vehicle 31 is present at the work sites 133 and 134 can be determined on the screen of the terminal 11.

[0442] When the vehicle 31 under management deviates from the management area ("Tokyo") 135, the information "out of the management area" is automatically transmitted.
It can also be displayed on the aforementioned “notification screen” in FIG. As a result, the manager can know that the vehicle 31 is "outside the management area", and can take quick and appropriate measures against an abnormal situation.

The management terminal 1 for managing the vehicles 31 and 32
It is also possible to allow the display of the “entry / exit screen” of FIG. 36 only on the first display screen and not to display the “entry / exit screen” on the display screens of the terminals other than the terminal 11. This is realized by, for example, displaying the “entrance / exit screen” in FIG. 36 on the condition that a specific ID number and a specific password (a number corresponding to the terminal 11) are input.

By the way, the construction machine 31, 3 to the rental destination
2 or construction machines 31 and 32 from the rental destination
Is carried out by mounting the construction machines 31 and 32 by the trailer 35. Since the transportation cost by the trailer 35 is high, it is necessary to increase the efficiency of transportation by the trailer 35 and keep the transportation cost low. In addition, it is necessary to increase the efficiency of transportation by the trailer 35 and to quickly carry in or collect from the rental destination, thereby increasing rental opportunities and increasing operating profit.

Next, referring to FIG. 37, the construction machines 31, 3
An embodiment that can improve the transportation efficiency of No. 2 will be described.

As described with reference to FIG. 36, on the terminal 11 side, information as to whether or not the vehicles 31, 32 have entered and exited the sales offices 130 to 132 and the vehicles 31, 32 have been transmitted to the respective work sites 133 and 134. It manages information on whether or not it is carried in and out of the facility.

Now, at the terminal 11 side, as shown in FIG. 37 (a), "the vehicle 31 enters the branch 130,
And the carry-in / out information that "the vehicle 32 is carried in to the vehicle". At this time, it is assumed that there has been a request that "the vehicle 31 is carried into the work site 133 and the vehicle 32 is carried out from the work site 134". Then, based on the entry / exit information and the carry-in / out information, the terminal 1
1 to the trailer 35, the "vehicle 31 of the branch 130"
To the work site 133 and return to the work site
The work instruction data of "take out the vehicle 32 and collect it to the branch 130" can be sent by e-mail. In this case, in the same manner as described with reference to FIG.
The display screen of the on-board terminal 14 shows “the current position of the trailer 35 itself, the current position of the vehicle 31 (the position of the branch 130), the position of the work site 133, and the current position of the vehicle 32 (the work site 13
4) and a work instruction message "are displayed.
The operator of the trailer 35 can work efficiently according to the display screen of the terminal 14.

That is, the trailer 35 moves to the branch 130, loads the vehicle 31 and leaves the branch 130.
At this time, the exit information indicating that the vehicle 31 has exited from the branch 130 is automatically transmitted from the vehicle 31, and the contents of the “entry / exit screen” in FIG. 36 are updated. The trailer 35 carries the vehicle 31 and enters the work site 133 via the route 136. At this time, the carry-in information that the vehicle 31 has entered the work site 133 is automatically transmitted from the vehicle 31, and the carry-in / out history is updated.

[0449] The trailer 35 enters the work site 134 through the route 137 in an empty state. The trailer 35 loads the vehicle 32 and carries it out of the work site 134. At this time, vehicle 3
The unloading information indicating that 2 has been unloaded from the work site 134 is automatically transmitted from the vehicle 32, and the loading and unloading history is updated.

The trailer 35 carries the vehicle 32 and
Enter the branch 130 through 38. At this time, entry information that the vehicle 32 has entered the branch 130 is automatically transmitted from the vehicle 32, and the entry / exit history of the vehicle 32 is updated.

As described above, the trailer 35 can carry in the vehicle 31 and carry out and recover the vehicle 32 by one dispatch. Therefore, the time during which the trailer 35 is empty can be reduced, and the transportation efficiency can be improved.

FIG. 37 (b) shows another example of the carrying operation.

Now, on the terminal 11 side, as shown in FIG. 37 (b), "the vehicle 31 has been carried into the work site 133 and the vehicle 32 has been carried into the work site 134 (branch 13
0, 132), the entry / exit information and the carry-in / out information are acquired. At this time, it is assumed that there has been a request that “the vehicle 31 is carried into the work site 134 and the vehicle 32 is carried out from the work site 134”. Then, based on the entry / exit information and the carry-in / out information, the terminal 11 sends a message “The vehicle 31 of the work site 133 is carried out to the work site 134 to the trailer 35.
To the branch 1
Work instruction data of "recover up to 32" can be sent by e-mail. In this case, the display screen of the terminal 14 equipped with the trailer 35 displays the “current position of the trailer 35 itself, the current position of the vehicle 31 (the position of the work site 133), (The position of the work site 134), the position of the branch 132 and a work instruction message "are displayed. The operator of the trailer 35 can work efficiently according to the display screen of the terminal 14.

That is, the trailer 35 moves to the work site 133 via the route 139, loads the vehicle 31 and carries it out of the work site 133. At this time, carry-out information indicating that the vehicle 31 has been carried out of the work site 133 is automatically transmitted from the vehicle 31, and the carry-in / out history is updated. The trailer 35 carries the vehicle 31 and enters the work site 134 via the route 140. At this time, the carry-in information that the vehicle 31 has entered the work site 134 is automatically transmitted from the vehicle 31 and the carry-in / out history is updated.

The trailer 35 loads the vehicle 32 and carries it out of the work site 134. At this time, carry-out information indicating that the vehicle 32 has been carried out of the work site 134 is automatically transmitted from the vehicle 32, and the carry-in / out history is updated.

The trailer 35 carries the vehicle 32 and
Enter branch 132 through 41. At this time, entry information that the vehicle 32 has entered the branch 132 is automatically transmitted from the vehicle 32, and the entry / exit history of the vehicle 32 is updated.

As described above, the trailer 35 can transfer the vehicle 31 and carry out and recover the vehicle 32 by one dispatch. Therefore, the time during which the trailer 35 is empty can be reduced, and the transportation efficiency can be improved.

In FIG. 37, the positions of the vehicles 31 and 32 and
By comparing the work areas 133 and 134 having a certain size, the vehicles 31 and 32
3, 134. However, by comparing the current position of the vehicle 31 with the center positions Z, W of the work sites 133, 134, the vehicles 31, 3
It may be determined whether or not 2 exists in the work sites 133 and 134.

In the above-described embodiment, the vehicle 31 is set in a start lock state (hereinafter referred to as start lock) by remote control, and the vehicle 31 is set in a start lock released state (hereinafter referred to as start unlock) by remote control. On the other hand, the construction machine 31 does not normally operate during a specific time zone (17:00 to 8:00 outside a fixed time).
If the engine of the construction machine 31 is started and operated during this time zone, it is considered that an abnormality such as mischief has occurred. However, when the vehicle 31 is moved to the terminal 11 at the same time every day,
The task of locking and unlocking the start by remote control from the side is troublesome.

Therefore, data of a specific time zone is previously stored in terminal 1
An embodiment will be described in which the transmission is transmitted from the first side to the vehicle 31 and the vehicle 31 itself enters the start lock state when the specific time period is reached, and enters the start unlock state when the specific time period elapses.

FIG. 38 is a flowchart showing the processing procedure of the embodiment.

First, when the display screen of the terminal 11 is changed to the “engine restart prohibition setting screen” and the “time period designation” button is clicked, a display for designating the “lock start time Ts” is displayed. In response, the content of “lock start time Ts” is input, for example, as “PM 17:00”. As a result, the lock start time Ts of the vehicle 31 becomes “PM17: 0”.
"0" is set (step 701).

Next, a display for designating "lock end time Te" is displayed. In response, "lock end time T
The content of "e" is input, for example, as "8:00 AM".
As a result, the lock end time Te of the vehicle 31 becomes “AM8:
00 ”(step 702).

As a result, the setting data of the lock start time Ts and the lock end time Te is transmitted from the terminal 11 to the vehicle 31 by e-mail (step 703).

On the vehicle 31 side, when the data Ts and Te are received by the communication terminal 56 via the satellite communication antenna 58,
This data is stored in the memory in the communication terminal 56 (Step 704). A calendar and a timer are provided inside the communication terminal 56 of the vehicle 31. The current time Tn is obtained from the internal calendar and the timer (step 705).
Next, the current time Tn is compared with the lock start time Ts and the lock end time Te (steps 706 and 707).

The current time Tn is the lock start time Ts (PM1
7:00) and the lock end time Te (8:00 AM)
(Steps 706 and 707)
YES), the communication terminal 56
A start lock setting command is output to the start lock circuit via the control circuit 4. For this reason, the relay of the start lock circuit is energized to be in the start lock state. That is, even if the key switch 64 is turned on, fuel is not injected and the engine of the vehicle 31 is not restarted (step 708).

The current time Tn is the lock start time Ts (PM1
7:00) It is time before or lock end time Te
If it is time after (AM 8:00) (step 706)
(NO at step 707, NO at step 707), a start lock release command is output from the communication terminal 56 to the start lock circuit via the communication controller 54. As a result, the relay of the start lock circuit is deenergized and the start is unlocked. That is, when the key switch 64 is turned on, fuel is injected and the vehicle 3
The engine No. 1 can be restarted (step 709).

As described above, every day at a specific time zone (17:00)
(0-8: 00), the vehicle 31 automatically enters the start lock state, and automatically enters the start unlock state after a specific time period.

In FIG. 38, the start of the vehicle 31 is locked every day. However, the start may be locked only on a specific day of the week. In this case, in steps 701 and 702, specific days of the week to be locked for starting (for example, Saturday and Sunday) are set.

Since the construction machine 31 does not operate during a specific period (for example, at the end of the year or at the beginning of the year), it is necessary to keep the start locked state during this period to prevent tampering. Further, in the construction machine 31 to be rented, it is necessary to keep the startup locked state after the end of the rental period in order to prohibit the use of the contract violation when the rental period ends.

FIG. 39 is a flowchart showing a processing procedure of the embodiment in which the starting lock is set after the rental period has elapsed.

First, a customer (user) uses the terminal 11 for managing the vehicle 31 for a period of use (for example, the AM on March 3).
From 8:00 to 8:00 PM on March 15), an application is made (step 801). Next, the vehicle 31 is delivered to the user (step 802). Steps 801 and 802
Application and delivery procedures can be performed by communication on the Internet 2.

Next, when the display screen of the administrator's terminal 11 is changed to the “engine restart prohibition setting screen” and the “use period designation” button is clicked, a display for designating the “use start date and time Ds” is displayed. . In response to this, the content of “use start date and time Ds” is input, for example, “March 3, 8:00 AM”. As a result, the use start date and time Ds of the vehicle 31 is set to “March 3, 8:00 AM” (step 80).
3).

[0474] Next, a display for designating "use end date and time De" is displayed. In response to this, "the use end date and time De"
Is input, for example, "March 15 PM 8:00". As a result, the use end date and time De of the vehicle 31 is set to “March 15 PM 8:00” (step 80).
4).

As a result, the setting data of the use start date and time Ds and the use end date and time De are transmitted from the terminal 11 to the vehicle 31 by e-mail (step 805).

[0476] On the vehicle 31 side, when the data Ds and De are received by the communication terminal 56 via the satellite communication antenna 58,
This data is stored in the memory in the communication terminal 56 (Step 806). A calendar and a timer are provided inside the communication terminal 56 of the vehicle 31. The current date and time Dn is obtained from the internal calendar and the timer (step 807).
Next, the current date and time Dn, the use start date and time Ds, and the use end date and time D
e is compared (steps 808, 809).

The current date and time Dn is past the use start date and time Ds (March 3 AM 8:00), and the use end date and time De (March 15 P
(M8: 00) (step 8)
08, 809), the communication terminal 56 outputs a start lock release command to the start lock circuit via the communication controller 54. As a result, the relay of the start lock circuit is deenergized and the start is unlocked. That is, when the key switch 64 is turned on, fuel is injected and the engine of the vehicle 31 can be restarted (step 810).

The current date and time Dn is a time before the use start date and time Ds (March 3 AM 8:00) or the use end date and time De.
If the time is after (8:00 on March 15 8:00) (NO in step 808, NO in 809), a start lock setting command is output from the communication terminal 56 to the start lock circuit via the communication controller 54. . For this reason, the relay of the start lock circuit is energized to be in the start lock state. That is, even if the key switch 64 is turned on, fuel is not injected and the engine of the vehicle 31 does not restart (step 811). By this, rental period (Ds-De)
Upon termination, the use of breach of contract is prohibited. Rental period (Ds-De) for vehicles 31 whose engine cannot be started
It becomes possible to collect at any time after the end (step 812).

In FIG. 39, the start and end periods (Ds to De) are set in steps 803 and 804 in order to lock the start at the end of the year and the beginning of the year and to unlock the start after the end of the year and the start of the year. Then, the contents of step 810 may be set to “start lock”, and the contents of step 811 may be set to “start unlock”. As a result, the start lock state is established during the end of the year and the beginning of the year (Ds to De) (step 8).
10) During the period other than the end of the year and the beginning of the year (Ds to De), the start-up is unlocked (step 811).

In FIGS. 38 and 39, one vehicle 31
, Data is transmitted from the terminal 11 to automatically lock the vehicle 31 to start. However, the terminal 11 may simultaneously transmit data to a plurality of vehicles (for example, the vehicles 31 and 32) to automatically lock the start of the plurality of vehicles.

By combining the embodiment shown in FIG. 39 and the embodiment shown in FIG. 37, it is possible to prevent the use of a contract breach after the end of the rental period and to efficiently collect the contract after the end of the rental period. That is, FIG.
In the case of (1), the customer leaves the vehicle 32 at the work site 134 after the rental period of the vehicle 32 ends.
Even if the vehicle 32 is left unattended at the work site 134, after the rental period (Ds to De) ends, the vehicle is in the starting locked state, so that the customer cannot use the contract breach.
Then, when it is time to carry the vehicle 31 into another work site 133, the trailer 35 moves the vehicle 3 to the work site 133.
1 and the unloading and collection of the vehicle 32 left at the work site 134 are performed simultaneously. Thereby, the collection work after the rental period of the vehicle 32 ends can be efficiently performed.

In this embodiment, a construction machine is mainly assumed as the vehicle 31. In a construction machine, the operation of the revolving superstructure and the working machine becomes impossible because the engine cannot be restarted. Therefore, by setting the start-up locked state, it is possible to avoid the danger caused by careless operation of the work implement and the revolving superstructure. That is, the present embodiment can be applied not only to the prevention of unauthorized use after the rental period has elapsed but also to the use of safety measures such as malfunction prevention. For example, if the operating lever for the working machine of the construction machine 31 is erroneously operated by a person (for example, an elementary school student) who is not very skilled in the operation, the working machine is inadvertently activated and a dangerous state occurs. According to the present embodiment, it is possible to prevent an erroneous operation in which the work implement is inadvertently activated by setting the start lock state.

By the way, the management of the labor and the work process of the operator are important for the manager of the company which contracts the civil engineering work and causes the operator to operate the construction machine to perform the civil engineering work. For this reason, the operator is obliged to create a daily work report. However, conventionally, since the operation of reading and inputting the value of the service meter is forced, the operation of creating a daily work report is cumbersome and imposes a heavy burden on the operator. Further, since the input operation is a manual operation, an inaccurate work daily report may be created due to an input error or the like.

The daily work report is useful information not only for a construction company that is a user of a construction machine, but also for a rental company that rents construction machines, a second-hand dealer that sells used construction machines, and a manufacturer that manufactures construction machines. It is. That is, for the rental company, by grasping the history of the work daily report, it is possible to discriminate between a customer who uses severely and a customer who does not use it, which can be useful for customer management. Also, for used dealers who sell used construction machinery, it is possible to calculate the past usage time and utilization rate of construction machinery by grasping the history of work daily reports, which can be used for setting used car prices. . Further, the manufacturer of the construction machine can calculate the durability of the construction machine by grasping the history of the work daily report, which can be used for designing the next model.

For this purpose, it is necessary that the information of the daily work report can be easily obtained from each terminal in real time.

Next, an embodiment will be described in which a daily work report can be accurately created without imposing a burden on the operator, and information of the daily work report can be easily obtained in real time from a terminal.

[0487] The server terminal 21 is a terminal provided to the maker, and a display screen of a home page called "work daily report screen" shown in FIG. 40 is created.

[0488] In the vehicle 31, every day at 23:00, the operation map, date, and operation time (Fig. 40) up to time 23:00 of the day are automatically transmitted. Here, the operation map refers to the output of the service meter (whether or not the engine is operating) provided in the vehicle 31 and the output of the calendar and timer provided in the vehicle 31 for each time, and the engine is operated. It is a table that shows the time zone during which it is running.
In FIG. 40, the time zone painted in black corresponds to the time zone in which the engine of the vehicle 31 is operating. The operating time refers to the accumulated value of the service meter per day (the operating time of the engine per day).

That is, the “operation map” automatically transmitted by the vehicle 31 and automatically transmitted by the server terminal 21,
When the mobile terminal information of “date” and “operating time” is received, the server terminal 21 performs a process of updating the “work daily report screen” on the homepage with the mobile terminal information.

[0490] Therefore, when the WWW browser is started on the terminal 11, the home page data is read from the server terminal 21 via the WWW browser, and the "work daily report screen" is displayed on the display screen of the display device of the terminal 11. .

For this reason, as shown in FIG. 40, the “date”, “operation map”, and “operation time” when the vehicle 31 operates are updated with the latest data and displayed. The “work daily report screen” includes “customer name” using the vehicle 31.
(ABC Civil Engineering Co., Ltd.), the “work site name” where the vehicle 31 is operating (Iroha crushed stone site), the “worker name” for each day, and “special notes” such as maintenance are also displayed. The input procedure of “customer name”, “work site name”, “operator name”, and “special notes” can be performed by communication on the Internet 2. When the "customer name", "work site name", "operator name", and "special notes" are input at the terminal on the customer side, the input data is transmitted to the server terminal 21 via the Internet 2, and according to the input data. The contents of the “work daily report screen” are updated.

As described above, the latest work daily report is stored in the terminal 1
1 is displayed on the display screen in real time, and can be easily obtained from the display screen of the terminal 11. In other words, the daily work report is created accurately without imposing a burden on the operator. This allows the construction company to perform labor management and work schedule management accurately.

When the terminal 11 is provided at a rental company, the history of the work daily report can be grasped from the display screen of the terminal 11, and it is possible to discriminate between customers who use severely and those who do not. This can be useful for customer management. For example, it could warn abusive customers or make a decision not to allow rentals. Further, by grasping the history of the daily work report, it is possible to find a customer who operates the vehicle 31 hardly, and advise the customer to return it. Further, by grasping the history of the work daily report, it is possible to predict when maintenance is to be performed on the vehicle 31.

When the terminal 11 is provided to a used dealer who sells used construction machines, the history of the work daily report can be grasped from the display screen of the terminal 11, and the past use time and operation rate of the construction machines can be grasped. Etc. can be calculated. As a result, the used car price can be set appropriately.

If the terminal 11 is provided by a manufacturer that manufactures construction machines, the history of the work daily report can be grasped from the display screen of the terminal 11, and the durability of the construction machine can be calculated. This can be useful for designing the next model.

Also, as shown in FIG. 41, the history of the service meter may be graphically displayed on the display screen of the terminal 11.
The horizontal axis of the graph in FIG. 41 is the date and time, and the vertical axis is the accumulated value of the engine operating time measured by the service meter. FIG.
The maintenance time such as the time of the periodic inspection can be predicted from the graph of FIG.

It is to be noted that the display shown in FIGS. 40 and 41 is permitted only on the display screen of the terminal 11 that manages the vehicle 31, and the display screens of terminals other than the terminal 11 are not displayed on the display screens of FIGS. It is possible. This corresponds to, for example, FIGS.
1 is displayed as a specific ID number, a specific password (terminal 1
This is realized by making the input operation of a number corresponding to 1) a condition.

In this embodiment, it is assumed that the “operation map” is created by the vehicle 31 and then transmitted to the server terminal 21. However, only the output of the service meter and the output of the calendar and timer provided in the vehicle 31 are transmitted from the vehicle 31, and the “operation map” is transmitted to the server terminal 2.
It is also possible to carry out the creation in step 1.

In the above-described embodiment, an operation map is generated every day, and a daily work report is generated every day.
The daily work report screen is updated every day. However, the unit of the operation map is not limited to one day, but may be any period. For example, an operation map may be generated on a monthly basis, a “work monthly report” may be created on a monthly basis, and the “work monthly report screen” may be updated on a monthly basis. It is also possible to create a work report for each rental period to the customer. That is, an operation map may be generated for each rental period to create a “work report”, and the “work report screen” may be updated.

When renting the construction machine 31, it is general to set and rent a charge according to the length of the rental period. However, even during a rental period of the same length, a customer who operates the construction machine 31 for a long time,
It is also true that there are both customers who rarely operate. In this case, it is unfair and unreasonable to charge the same rental fee to both parties.

Therefore, the charge may be automatically calculated according to the length of the engine operation time.

[0502] That is, in the server terminal 21, data of "operating time" automatically transmitted from the vehicle 31 (output of the service meter) and data of "date and time" (output of the calendar and timer provided in the vehicle 31) Is received, and these are matched to perform an arithmetic process of accumulating the “operating time” up to the present in the “rental period”. On the other hand, the correspondence between the accumulated value of the operating time and the billing amount is set in advance. Therefore, a billing amount corresponding to the accumulated value of the operating time up to the present is calculated from this correspondence. Server terminal 2
In step 1, processing for updating the "work daily report screen" on the homepage with the latest charge amount is performed.

[0503] Therefore, when the WWW browser is started on the terminal 11, the home page data is read from the server terminal 21 via the WWW browser, and the "work daily report screen" is displayed on the display screen of the display device of the terminal 11. . It is assumed that the rental period is from January 21 to January 30. In the “work daily report screen” of FIG. 40, the accumulated value of the operating hours during the rental period (January 21 to January 30), that is, the value obtained by summing up the daily “operating hours” during the rental period (49 hours 6 minutes) ) Is displayed. As a result, the customer can easily obtain the information of the billing amount corresponding to the time during which the engine has been operated during the rental period on the screen in real time.

In this embodiment, only the output of the service meter, the output of the calendar and the timer provided in the vehicle 31 are transmitted from the vehicle 31, and the “bill amount” is created by the server terminal 21. However, it is also possible to calculate the “billing amount” in the vehicle 31 and then automatically transmit the calculated billing amount to the server terminal 21.

In the embodiment described above, the billing amount is simply calculated according to the accumulated value of the operating time.

[0506] However, in actuality, demand for construction machinery greatly changes depending on the timing. Specifically, demand for construction machinery increases during periods of heavy construction. Also, during the day, demand is greater during the daytime than at night. Therefore, the billing amount may be set according to the demand of the construction machine. Specifically, when the construction is concentrated, the demand for construction machinery increases, so that the billing amount can be set higher, and conversely, the billing amount can be set lower during the off-season. In addition, the billing amount can be set higher during the daytime and the billing amount can be set lower during the nighttime. Therefore, the billing amount can be determined in consideration of not only the accumulated value of the operation time but also the operation time, the operation time zone, and the operation time.

[0507] In this embodiment described above, the communication means 1 including the Internet 2 is assumed, but the communication means 1 of the present invention is not limited to this. It is also possible to build In short, if communication equivalent to that described in the embodiment is performed, it is possible to substitute another communication means. Further, in the present embodiment, the communication unit 1 in which the wireless communication and the wired communication are combined is assumed, but it is needless to say that only the wireless communication may be performed, or the wired communication may be performed only.

[0508] Furthermore, in the present embodiment, a presentation format in which mobile object information is displayed on a terminal as image data is assumed, but the present invention provides mobile terminal information by outputting it as audio to the terminal. Alternatively, the terminal may be printed out as print data. In short, the presentation format of the mobile object information at the terminal is arbitrary.

In this embodiment, it is assumed that a plurality of moving objects including construction machines are managed and monitored.
The present invention is not limited to this, and can be applied to the case of managing and monitoring general automobiles, motorcycles, and the like.
