That is, a response request signal is transmitted from the communication satellite 9 to the mobile work machine 31 via the wireless communication line 5. The response request signal is transmitted from the communication satellite 9 side to the mobile work machine 31 because it is often unknown whether communication is possible, such as when the mobile work machine 31 is in an environment where the communication state is not good. Done. On the other hand, the mobile work machine 31
The confirmation of the presence or absence of the response request signal from the side to the communication satellite 9 is performed intermittently. The presence / absence of the response request signal is confirmed by sensing a radio wave indicating the response request signal transmitted from the communication satellite 9. Therefore, communication satellite 9
The request can be surely transmitted from the side to the mobile work machine 31. 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 predetermined time has elapsed after the specific event occurred.

For example, it is possible to detect the start of the engine of the mobile work machine 31 and use this detection signal as a trigger to confirm the presence or absence of the 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 on the day.

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

Further, it is possible to confirm the presence / absence of the response request signal at a time point when a predetermined time has passed since the last transmission by the mobile work machine 31, and perform the next transmission.

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

As a result of the confirmation of the presence / absence of the response request signal, when the response request signal is present, the mobile work machine 31
The data indicating that the electronic mail in the own mailbox is received is transmitted to the server terminal 21 via the communication satellite 9. As a result, from the server terminal 21 to the mobile work machine 31
An email will be sent to.

That is, the electronic mail is transmitted to the network control station 7 via the Internet 2, and the data of the electronic mail is protocol-converted. Then, the protocol-converted electronic mail is sent to the private line 3. Then, the electronic 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 is 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 electronic mail received by the satellite communication antenna 58, and uses this as the request information identification data D3. The communication controller 54 is instructed to acquire corresponding mobile 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 vehicle position data currently detected by the GPS sensor 57 is sent 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 sent to the signal line 52. The electronic controller 53 reads the description content of the frame signal, collects the current fuel amount detection data from the sensor group 62 of the electronic controller 53, and describes it in the frame signal. Then, this frame signal is sent to the communication controller 54 via the signal line 52. The communication controller 54 reads the fuel amount data described in the frame signal and sends it to the communication terminal 56. As a result, the communication terminal 56 captures the vehicle position data and the fuel amount data in the reply e-mail as the mobile body information data D3 '.

(Mobile work machine 31), reply destination identification data D4 (terminal 12) indicating the terminal of the reply destination, and mobile body information data D3 '(vehicle position data and fuel amount data) indicating mobile body information are predetermined. It is transmitted to the communication satellite 9 as a reply electronic mail with a data structure according to the communication protocol. Note that D1 and D3 are also transmitted at the same time. D1 can be used as a distribution key for each charge destination of the communication charge. Further, D3 is used for identifying the contents 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 through the feeder line 4, the satellite earth station 8 and the dedicated line 3. The network control station 7 protocol-converts the data of the reply e-mail, and sends the protocol-converted reply e-mail to the Internet 2.

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

Further, the mobile body information extraction program is executed to extract mobile body information data D3 '("vehicle position data", "fuel amount data") 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 body information data MD are updated.

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

When an electronic mail is received by the terminal 12 on the operator side of the mobile work machine transport vehicle 35, reply source identification data D2 (mobile work machine 31) and mobile body information data D3 '(vehicle position) are read from the data of the electronic mail. Data and fuel amount data) are read. Then, the content of the electronic 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.

Therefore, the operator of the transport vehicle 35 can recognize the model 31 of the specific mobile work machine whose transportation is instructed by the administrator from the display screen of the terminal 12, and the operator of the mobile work machine 31 can be recognized. It is possible to recognize the current position and the current fuel amount required for transportation. Moreover, the operator on the terminal 12 side can obtain only the information necessary for the work from the display screen of the terminal 12 without performing the information request input operation.

Checks the existence 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 between the transmission in 1) and the actual reception by the mobile body (e.g., mobile work machine 31) at the destination of the mail address.

In this embodiment, data is transmitted and received by satellite radio communication by the communication satellite 9. In the satellite wireless communication, if the communication environment between the transmitter and the receiver is not good such as the maximum elevation angle of the satellite is small and the line of sight with the moving body cannot be obtained, the communication line 5 cannot be secured, and therefore, the communication is repeated several times. Processing is performed. For this reason, the mobile body (for example, the mobile work machine 3
There is a delay due to the communication environment before the actual reception in 1).

As described above, in the communication system of this embodiment, there is a time difference of, for example, several minutes between the transmission of the electronic mail from the request source terminal and the reception of the request destination mobile unit. In such a low-real-time communication system, there is a risk that the operator of the requesting terminal may feel uneasy due to the unknown communication status and may affect work efficiency. Further, since the communication status is unknown, the duplicated electronic mail may be retransmitted, which may affect the communication cost.

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

Further, in this embodiment, a plurality of terminals request mobile unit information for one mobile unit. Therefore, how new the currently obtained mobile body information is (when the mobile body information was requested) cannot be judged by only one terminal. Therefore, on the display screen of the terminal, the time elapsed since the mobile unit was last requested is displayed, and the mobile unit management information on how new the currently obtained mobile unit information is is displayed. It is desired to inform the operator.

The embodiments described below meet these requirements.

That is, as shown in FIG. 31, on the terminal 11, an icon (picture of hydraulic excavator, picture of service car, picture of trailer, etc.) as a mobile body identifier is associated with each of a plurality of mobile bodies 31 to 35. ) Is displayed. Then, when an electronic mail requesting the mobile body information is transmitted from the requesting terminal 11 to the requesting mobile work machine 31, the icon of the mobile work machine 31 becomes as shown in FIG. The display content changes in the manner shown.

As described above, according to the present embodiment, since the elapsed time from the request to the mobile unit until the response is displayed, whether the communication is normally performed or not is displayed. Can be easily identified 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 in accordance with the communication state between the terminal 11 and the mobile work machine 31. However, it is also possible to change the combination of the colors of the icons, the color arrangement, the pattern of the filling, and the like. Moreover, you may change components other than a color.

For example, as shown in FIG.
The shape of the icon of the mobile work machine 31 may be changed and displayed depending on the communication state between the mobile work machine 31 and the mobile work machine 1. For example, if it is a hydraulic excavator icon,
You can change the position and roundness of the work equipment.

The icons 7 and 38 can be displayed on the screen in a preset order.

Further, as shown in FIG. 17B, the icons of the mobile work machines 31, 32, 33, 36, 37, 38 are rearranged according to the communication state, and the movement corresponding to "requesting" is performed. The icons of the work machines 31, 32 are displayed on the upper level, and the work machines 33, 36 corresponding to “no request” are displayed.
It is also possible to display 37 icons at the lower level.

As shown in FIG. 17C, the mobile work machines 31, 3 corresponding to “requesting” among the icons of the mobile work machines 31, 32, 33, 36, 37, 38.
Only the two icons may be extracted and displayed.

As described above, according to the present embodiment, the display content of the terminal is changed according to the change of the communication state, so that the deterioration of the work efficiency due to the unknown communication state can be prevented and the communication cost can be increased. Can be prevented. Further, it is possible to obtain, from the display screen, management information (whether maintenance or inspection has been recently performed) on how new the mobile body information of each mobile body is.

The embodiment in which the display contents of the terminal are changed according to the change of the communication state can be applied to any communication system without being limited to the communication system shown in FIG. It is applicable to any communication system including at least two communication stations and performing communication between the two communication stations.

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

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

In FIG. 21, it is assumed that the battery 63 (rated voltage 24
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 battery 63 rapidly discharges. On the other hand, if the electrical connection between the battery 63 and the communication terminal 56 is always turned off while the engine is off, a plurality of terminals 1
Communication with 1, 12, ... Is impossible. Therefore, when a request for mobile body information is made from the terminals 11, 12 ... 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 in which the engine is not in operation for a long time is used.
~ 35, even if the plurality of terminals 11 while the engine is off,
It is possible to enable communication with the terminals 12 and 12 to respond to requests from the terminals 11 and 12, and to suppress unnecessary power consumption. FIG. 21 shows the configuration of this embodiment.

As described with reference to 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 the power of the battery 63 to this main power supply circuit. Communication terminal 5
An internal program (software timer) is stored in 6 or an internal power supply circuit (hard timer) is incorporated, and by these, the drive of the main power supply circuit is intermittently turned on and off, and the main power supply is periodically cycled. 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 it 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. Alternatively, the main power supply circuit may be driven by hardware.

That is, when the off signal (logic "0" level signal) of the engine key switch signal S1 is input to the sleep control terminal of the communication terminal 56, the main power circuit in the communication terminal 56 and the battery 63 Electrical connection is turned on and off at a predetermined duty ratio, driving of the main power supply circuit is turned on and off, the communication terminal 56 is turned on and off, and communication processing is performed in a constant cycle (of the communication terminal 56). Sleep function is on).

In response to the ON signal (logic "1" level signal) of the engine key switch signal S1 being input to the sleep control terminal of the communication terminal 56, the main power circuit in the communication terminal 56 and the battery 63 are electrically connected. , 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 (forced release)). Therefore, while the engine is on, the communication terminal 56 is always available.
Is activated.

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
The electrical connection with 3 is cut off, 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, the processing performed by the communication terminal 56 will be described with reference to the timing chart shown in FIG.

FIG. 7A shows the operation signal S1 of the engine key switch 64, and FIG. 7B shows the communication state between the communication terminal 56 and the communication satellite 9. Logical "1" during communication
Shown by level. FIG. 7C shows the activated state of the communication terminal 56. The logic "1" level corresponds to the activation state (power saving operation is off), and the logic "0" level corresponds to activation off (sleep) state (power saving operation is on). The duty ratio D (= (τ /
T) × 100%) and is turned on and off intermittently. At the timing at which the power saving operation is turned off and the communication terminal 56 is activated, the communication terminal 56 moves the current position, the service meter value, the remaining fuel amount, the battery voltage, the vehicle body error code, and the like 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 started up with a duty ratio D (= (τ / T) × 100 as shown by an arrow a.
%) To turn on and off intermittently (sleep function is on).

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

As shown in these figures, the time τ which is always activated within a fixed time (activation cycle) T, that is, the communication satellite 9
There is a time that can be sent and received to and from (Fig. 8 (c)).
See the diagonal line). The expected value of the communication response time is T / 2 (average is T / 2). Moreover, the 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 in the power saving mode at the startup cycle T, the communication satellite 9 continuously transmits a signal to the communication terminal 56 for a time period of T or more. Need to be (Fig. 8 (b),
(See (c)). The starting 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 activation time τ longer than the time required for the transmission / reception procedure. However, the smaller the startup time τ, the greater the power saving effect.

As described above, by periodically activating the communication terminal 56 at the cycle T, the expected value of the communication response time can be secured and the power consumption can be suppressed.

However, as shown in FIG. 7, even if the engine key switch signal S1 is switched from ON to OFF,
If communication is being performed between the communication terminal 56 and the communication satellite 9 as shown by arrow c, the sleep function is turned on from the time when communication is completed as shown by 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 operates and the communication terminal 56 is always activated during the engine operation. It is possible to transmit information on a moving body such as an abnormal vehicle, and to ensure 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 characteristic shown in FIG.

That is, as the voltage of the battery 63 becomes lower, the duty ratio D becomes smaller and the starting cycle T becomes longer, so that the further decrease in the voltage of the battery 63 can be suppressed.

Further, with the characteristics similar to those shown in FIG. 8A, the duty ratio D is decreased and the starting cycle T is lengthened as the operating time of the engine is shortened, whereby the voltage of the battery 63 is further reduced. May be suppressed.
The operating time of the engine is calculated from the increase value of the service meter. The continuous operating 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 operating time. . In this case, the battery voltage input circuit need not be provided.

According to the configuration shown in FIG. 21, the power saving operation is performed by the process in the 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 adopted instead of the configuration of FIG. That is, a device other than the communication terminal 56, for example, a communication controller 54 is provided with a power saving operation control function when the engine key switch 64 is off, and the communication controller 54 establishes an electrical connection between the communication terminal 56 and the battery 63. The on / off control may be performed intermittently.

That is, as shown in FIG. 22, the communication terminal 56
The power terminal of the battery 63 through the power switch 65
Electrically connected to. When 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. In addition, the operation signal S1 of the engine key switch 64 is the communication controller 5
4 is input. Further, the signal S3 indicating the 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 status signal S
3 is a logical "1" level.

A software timer is stored in the communication controller 54 or a hardware timer is built in, and the power switch drive signal S is sent to the power switch 65.
2 is output.

The communication controller 54 executes the same processing as described with reference to FIG.

FIG. 7A shows the operation signal S1 of the engine key switch 64 input to the communication controller 54, and FIG. 7B shows the communication terminal 56 to the communication controller 5
4 shows the communication status signal S3 inputted to the power supply switch 4, and FIG. 7C shows the power switch drive signal S2 outputted from the communication controller 54 to the power switch 65.

Therefore, similarly to the configuration shown in FIG. 21, when the operation of the engine is stopped (the signal S1 is off), the activation of the communication terminal 56 is turned on and off at a predetermined duty ratio D (the signal S2 is turned on). ,off). When the engine is operating (signal S1 is on), the sleep function is forcibly released and the communication terminal 56 is always activated during engine operation (signal S2 is on). Even if the engine stops operating, if communication is in progress (S3 is on), the communication terminal 56 remains activated until communication is completed (S2 is on).

Similarly, the duty ratio D can be changed according to the terminal voltage of the battery 63 and the operating time of the engine.

Various modifications can be made to the above embodiment. 13, FIG. 23, FIG. 24, and FIG. 25 will be described below.

The duty ratio D is determined by the mobile work machine 31.
It may be changed according to the position information of.

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

FIG. 23 (a) shows how the starting period 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 move by themselves. On the other hand, in the mobile work machine 31 such as a construction machine, there are few situations where it travels a long distance by self-propelled, and in most cases, the operation of the engine of the vehicle is stopped and the vehicle is loaded in a trailer or the like. To do.
And in this case, the trailer 35 managed by 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 an unmanaged trailer and illegally taken out overseas. In addition, there is a possibility that the mobile work machine 31 may be brought in by the trailer 35 carelessly and brought to a work site that is not administratively permitted without permission.

Therefore, when the operation of the engine of the mobile work machine 31 is stopped, the power consumption associated with communication is suppressed and the mobile work machine 31 is requested in response to a request from the terminal 11.
The moving position of the mobile work machine 3 is displayed on the terminal 11.
It is necessary to manage and monitor the movement trajectory of 1.

Then, on the map of the display screen of the terminal 11,
If it is normal, a predetermined range 117 in which the mobile work machine 31 will exist is set. This setting range 117
Is, for example, a management area in charge of the administrator on the terminal 11 side, an administratively approved work site, or the like.

The communication terminal 56 of the mobile work machine 31 is started up by a predetermined duty ratio D as shown in FIG.
It is turned on and off intermittently at (= (τ / T) × 100%). Then, as shown in FIG. 7C, the power saving operation is turned off (the power switch drive signal S2 is turned on), and the communication terminal 5
6 is activated, the communication terminal 56 responds to the request from the terminal 11 with respect to the communication satellite 9 at the current position (in addition to the mobile meter value, the remaining fuel amount, the battery voltage, the vehicle error code, and the like). Information may be included) is transmitted. As a result, the sequential moving 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 measurement device (GPS antenna 59, GPS sensor 57, communication controller 54) is low, these GPS measurement devices can be electrically connected directly to the battery 63 and can be operated constantly. When the power consumption of these GPS measuring devices is large, the sleep function is turned on to turn the power saving operation on and off in the same manner as the communication terminal 56, and the power saving operation is turned on (the communication terminal 56 is activated). The position may be measured by operating the GPS measuring device only during the time.

In the mobile work machine 31, the GPS sensor 57
A process of comparing the position detected in step 1 with the boundary position of the setting range 117 and changing the activation cycle T according to the comparison result is executed.

FIG. 23D shows how the starting cycle T changes in accordance with the relative position (passage of time) of the mobile work machine 31 with respect to the setting 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 starting 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 judged that an abnormal situation has occurred due to deviation from the normal range (movement outside the permitted area), and detailed information on the movement locus is obtained. In order to obtain, the activation period T becomes a period T2 shorter than the maximum period T1 (see FIG. 23 (d)).

The mobile work machine 31 has the normal setting range 11
Position D further separated from the boundary position of 7 by a predetermined distance L0
When it reaches, the starting cycle T becomes a cycle T3 which is shorter than the cycle T2 in order to obtain more detailed information of the movement trajectory (see FIG. 23 (d)). After that, the normal setting range 117
As the separation distance from the
(<T3) ... can be sequentially shortened to finally set the cycle to 0 (the duty ratio D = 1).

As shown in the graph of FIG. 23 (c),
The activation cycle T may be continuously shortened as the distance L to the boundary position of the normal setting range 117 increases.

As the activation cycle 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 automatically transmitting, the transmission interval of the 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 shows a more detailed movement locus (between the displayed movement positions). A moving path 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, since the duty ratio D for turning on and off the communication terminal 56 is increased as the mobile work machine 31 moves away from the normal setting range 117, power consumption accompanying communication is suppressed and an abnormal situation occurs. It is also possible to perform accurate monitoring for.

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

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

In the mobile work machine 31, the position detected by the GPS sensor 57 and the boundary position of the set range 118 are compared in the same manner as described with reference to FIG. A process of changing the activation cycle T is executed.

FIG. 23D shows how the starting cycle T changes in accordance with the relative position (passage of time) of the mobile work machine 31 with respect to the setting 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 starting 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 the dangerous area), and the start cycle is obtained in order to obtain detailed information of the movement locus. T becomes a cycle T2 shorter than the maximum cycle T1 (see FIG. 23 (d)).

The mobile work machine 31 has the abnormal setting range 11
Position D that further penetrates a predetermined distance L0 from the boundary position of 8
When it reaches, the starting cycle T becomes a cycle T3 which is shorter than the cycle T2 in order to obtain more detailed information of the movement trajectory (see FIG. 23 (d)). Unusual setting range 118
As the entry distance to the
(<T3) ... can be sequentially shortened to finally set the cycle to 0 (the duty ratio D = 1).

As shown in the graph of FIG. 23 (c),
The activation cycle T may be continuously shortened as the distance L to the boundary position of the abnormal setting range 118 increases.

In this way, as the mobile work machine 31 enters the abnormal setting range 118, the display screen of the terminal 11 which is the display destination terminal shows a more detailed movement trajectory (between the displayed movement positions). A moving path 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, since the duty ratio D for turning on / off the communication terminal 56 is increased in response to the mobile work machine 31 entering the abnormal setting range 118, power consumption associated with communication can be suppressed and at the same time, the abnormality can be dealt with. Precise monitoring can also be performed.

Note that the present invention is not limited to the abnormal situation monitoring assumed in FIGS. 23 (a) and 23 (b), but can also be applied to the case of monitoring the route until the mobile work machine 31 is discarded and disposed. .

In the embodiment shown in FIGS. 23 (a) and 23 (b), the distance L to the boundary between the setting ranges 117 and 118 is L.
Although the activation cycle T is uniquely determined only from the above, in addition to the distance L, the activation cycle T is further considered in consideration of the azimuth, the geographical information of the surroundings, the type of the moving body, the usage period of the moving body, and the like.
May be determined.

Also, as shown in FIG. 24, the mobile work machine 31
The duty ratio D may be changed according to the position change amount.

When the communication terminal 56 of the mobile work machine 31 is started, as shown in FIG.
It is turned on and off intermittently at (= (τ / T) × 100%). Then, as shown in FIG. 7C, the power saving operation is turned off (the power switch drive signal S2 is turned on), and the communication terminal 5
6 is activated, the communication terminal 56 responds to the request from the terminal 11 with respect to the communication satellite 9 at the current position (in addition to the mobile meter value, the remaining fuel amount, the battery voltage, the vehicle error code, and the like). Information may be included) is transmitted. As a result, the sequential moving 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 measurement device (GPS antenna 59, GPS sensor 57, communication controller 54) is low, these GPS measurement devices can be electrically connected directly to the battery 63 and can be operated constantly. When the power consumption of these GPS measuring devices is large, the sleep function is turned on to turn the power saving operation on and off in the same manner as the communication terminal 56, and the power saving operation is turned on (the communication terminal 56 is activated). The position may be measured by operating the GPS measuring device only during the time.

In the mobile work machine 31, the GPS sensor 57
Then, the current position detected at the time of this start and the circles 119 and 12 having a radius S centered on the position detected at the time of the previous start
The process of comparing the boundary position of 0 ... And changing the activation cycle T according to the comparison result is executed.

FIG. 24 (b) shows a starting cycle T depending on whether or not the mobile work machine 31 has escaped from the circle 119, 120, ...
Shows the change.

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 centered on the position A and having a radius S (km) is set on the map. It The initial activation period T is set to the maximum period T1. Therefore, the communication terminal 56 is activated after the cycle 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 activation cycle T is left at the maximum cycle T1. Further cycle T
It is assumed that the communication terminal 56 is started after 1 and the position detected by the GPS sensor 57 at that time is the position C outside the circle 119. In this case, the radius S with the position C as the center
A (km) circle 120 is set on the map and
The activation cycle T is changed to a cycle T2 shorter than the maximum cycle T1.

Therefore, the communication terminal 56 is activated after the cycle 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 left as the cycle T2. Further, it is assumed that the communication terminal 56 is activated after the cycle 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 centered at the position E
A (km) circle 121 is set on the map,
The activation 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 cycle T3 and the position detected by the GPS sensor 57 at that time is the 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 a cycle T shorter than the cycle T3.
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 the longer cycle T3 (see FIG. 24 (b)).

In the embodiment shown in FIG. 24 (a), the areas of circles 119, 120 ... Of radius S are set.
Alternatively, a square area whose one side is 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 this 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 determine whether or not the area is outside the area by subtracting the latitude and longitude on the map without performing any arithmetic processing.

Areas 119 and 1 shown in FIG.
It is also possible to implement 20 ... In shapes other than circles and squares. For example, an elliptical or rectangular area that is long in either the latitude or longitude direction may be used. Further, it may be an ellipse or a rectangle that is long in the traveling direction of the mobile work machine 31.
In this case, whether or not the mobile work machine 31 has escaped from the area can be determined more accurately and more quickly.

Further, the sizes 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 movement amount.

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 shows more detailed information. A movement locus (a movement locus with a short time interval between the displayed movement positions) is displayed. Therefore, the work is completed at a certain work site, and the mobile work machine 31
The situation where the person is moving to the next work site can be accurately grasped on the terminal 11 side. Therefore, the work efficiency of process control and transportation control is dramatically improved. Moreover, since the duty ratio D for turning on and off the communication terminal 56 is increased in accordance with the increase in the moving speed of the mobile work machine 31, accurate monitoring while moving and suppression of power consumption accompanying communication are performed at the same time. Can be realized.

In the embodiment shown in FIG. 24, the activation cycle T is changed according to whether or not the areas 119, 120, ... Set sequentially are exceeded, but as shown in the graph of FIG. The moving speed V of the work machine 31 may be calculated for each startup cycle T, and the startup 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, as in the embodiment shown in FIG.

Then, the following equation, V = (detection position at the time of this start-detection position at the time of previous start)
/ The moving speed V is calculated according to the current starting cycle T.

The relationship between the moving speed V and the starting cycle T is shown in the graph of FIG. When the moving speed V is sufficiently low, that is, the speed V1 (= 3 km / h) or less, the activation cycle T is set to the maximum cycle T1 (= 10 minutes). From traveling speed V1 to cruising speed V2 (= 50
As it increases up to km / h), the activation cycle T becomes shorter. When the traveling speed V reaches the cruising speed V2, the activation cycle T is 0 (duty ratio D is 1), that is, the communication terminal 5
6 is in a continuous activation state.

Moving speed V obtained in accordance with the above equation
The start-up cycle T is determined by obtaining the start-up cycle T corresponding to the from the graph shown in FIG.

Therefore, the activation cycle T becomes shorter as the moving speed V of the mobile work machine 31 becomes faster, and a more detailed movement locus (each displayed movement is displayed) on the display screen of the terminal 11 which is the display destination terminal. Trajectory with short time intervals between positions)
Will be displayed. Therefore, 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. It is possible to constantly monitor the situation where the machine 31 is loaded and running on the display screen of the terminal 11. Therefore, the work efficiency of process control and transportation control is dramatically improved. Moreover, since the duty ratio D for turning on and off the communication terminal 56 is increased in accordance with the increase in the moving speed of the mobile work machine 31, accurate monitoring while moving and suppression of power consumption accompanying communication are performed at the same time. Can be realized.

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

For example, the communication terminal 56 can be activated at a specific time when communication between the communication satellite 9 and the mobile work machine 31 is favorably performed. This specific time corresponds to the position (altitude) of the communication satellite 9.

FIG. 13A shows the positional relationship between the communication satellite 9 and the mobile work machine 31. In the communication path (wireless communication line 5) between the communication satellite 9 and the mobile work machine 31, there is an obstacle 123 in communication such as a mountain or a building.

When the altitude of the communication satellite 9 is large (when the maximum elevation angle is large), the communication obstacle due to the obstacle 123 is reduced and the communication state is improved. Therefore, when the altitude of the communication satellite 9 reaches a high 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 side to store and store the information on the arrival position of the communication satellite 9.

The arrival position information of the communication satellite 9 varies from day to day. Therefore, if the flying position information for all dates is stored and stored in the memory of the mobile work machine 31,
Insufficient memory capacity and occupancy of memory will occur.

Therefore, in this embodiment, as shown in FIG. 13A, the arrival position information 124 having a predetermined amount of information 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. It is determined whether or not to activate the communication terminal 56 by comparing the incoming position information 124 received therewith with the time measured by the clock.

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

In FIG. 13B, "AOS" indicates the time and azimuth angle at which the communication satellite 9 appears on the horizon, and "AOS" indicates "ME".
“L” indicates the time and azimuth when the communication satellite has the maximum elevation angle, and “LOS” indicates the time and azimuth when the communication satellite 9 disappears on the horizon. The path of the communication satellite 9 corresponding to the enclosed portion is shown in FIG. 13 (c).

In the communication terminal 56 of the mobile work machine 31, the time at which the maximum elevation angle of a predetermined threshold value (for example, 45 degrees) or more is obtained from the flying position information 124 shown in FIG. 13B, that is, the maximum elevation angle 66 °, Time 4: 3 when 54 ° is obtained
At 3:16:28, the 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 mobile unit information is transmitted to the communication satellite 9 via the wireless communication line 5.

In the arrival position information 124, 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, for example.
As a result, the contents of the incoming position information 124 stored in the memory of the mobile work machine 31 are updated.

As described above, according to the embodiment shown in FIG. 13, the communication terminal 56 is activated at a specific time when communication between the communication satellite 9 and the mobile work machine 31 is favorably performed. Therefore, power saving can be achieved, and communication between the communication satellite 9 and the mobile work machine 31 can be reliably performed. Further, since the flying position information 124 is received from the outside by communication, the problem of insufficient memory capacity and memory occupation on the mobile work machine 31 side does not occur.

Further, 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 period T from 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 with the mobile work machine 31 as the mail address. Then, the change data described in the electronic mail is read at the communication terminal 56 of the destination mobile work machine 31, and the activation cycle T is 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 activation cycle T is shortened in order to frequently monitor the status at short intervals, and it is lent to a certain user. In order to reduce unnecessary power consumption and communication charges when monitoring (when monitoring is not necessary) or when the vehicle has been suspended for a long time (when it is clear that the operation is stopped) In addition, the activation cycle T is lengthened. It should be noted that a plurality of moving bodies that are working or traveling in a group may be changed to the same activation cycle T all at once.

Thus, according to this embodiment, the terminal 11
On the side, the activation cycle T can be changed by remote control while monitoring the situation of the moving body and the surrounding situation. For this reason, it is not necessary for the worker to go to each location of the moving bodies 31, 32, ... To perform the work of changing the activation period T, and the work load is significantly reduced.

As described above, according to this embodiment, the moving body 3 such as a construction machine in which the engine is not in operation for a long time is long.
1 to 35 even when the engine is off
It becomes possible to communicate with the terminals 1, 12 ... And to respond to requests from the terminals 11, 12 ... And at the same time, wasteful power consumption is suppressed.

This embodiment of intermittently turning on the power supply for communication is not limited to the communication system shown in FIG. 1 and can be applied to any communication system. It is applicable to any communication system including at least two communication stations and performing communication between the two communication stations.

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

In the embodiments described below, even when there is no request from the terminal side, if the parameter reaches a specific value inside the mobile body, the specific mobile body information is voluntarily transmitted and the specific side is specified to the terminal side. The mobile unit information is displayed.

According to this embodiment, it is possible to recognize an abnormal situation (for example, a failure) that has occurred in a moving body that cannot be constantly managed and monitored on the terminal side, and the operating state of the moving body,
It is possible to accurately grasp the state of rest.

As shown in FIG. 2, a parameter inside the mobile work machine 31, for example, an engine starting state is detected by a predetermined sensor in the sensor group 62 (for example, a sensor for detecting the voltage value of the alternator). And As described above, the detection signal of this sensor is described in the frame signal by the electronic controller 53 and is sent 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 input to the communication terminal 56 of the mobile work machine 31 to indicate the starting state of the engine. FIG. 26A shows the engine start state of the mobile work machine 31 at each time t on one day (from time 6:00 to next 6:00), and the logic "1" level indicates that the engine is operating (starting). ), The logical "0" level corresponds to the state where the engine operation is stopped.

Automatic transmission from the mobile work machine 31 can be performed at every engine start, as shown in FIG. 26 (b), for example.

That is, as shown in FIG. 26 (a), time t
When the engine is started at 1 and a signal indicating that the engine is started is input to the communication terminal 56, the signal is used as a trigger to indicate specific mobile body information, that is, for example, the mobile work machine 31 as indicated by an arrow e. The current position is captured in an electronic mail and transmitted to the communication satellite 9 as an electronic mail. The destination email address of this email is the server terminal 21. By the power saving operation described above, the communication terminal 5
If 6 is sleeping, it is sent after the engine has been started and forced startup has taken place.

Therefore, assuming that the server terminal 21 is the terminal on the manager side, the display screen of the terminal 21 on the manager side displays the successive positions each time the engine of the mobile work machine 31 is started. become. Therefore, the administrator can grasp the history of the position every time the engine is started in 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 an abnormal situation that occurred in
It is possible to accurately grasp the operating state and the resting state of the mobile work machine 31.

From the mobile work machine 31 to another terminal 11,
The electronic mail may be transmitted by using the terminal 12 ... As the destination mail address.

The automatic transmission from the mobile work machine 31 is
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. 26 (a), time t
When the engine is started in 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 whether or not this start signal is the signal input first in one day (from 6:00 to the next 6:00) Is judged. Only when it is determined that the input start signal is the start signal input first in one day, the mobile work machine 3 is triggered by this start signal as indicated by arrow f.
The current position of 1 is captured in an electronic mail and transmitted to the communication satellite 9 as an electronic mail. Therefore, similarly, the history of the position of the mobile work machine 31 is displayed on the terminal on the manager side. According to the present embodiment, as compared with the case of FIG. 26B, the interval of automatic transmission is at least every one day, so the communication cost can be suppressed.

[0308] 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 first started in one week. The automatic call may be made only when a call is made.

[0309] Further, the automatic transmission from the mobile work machine 31
As shown in FIG. 26 (d), it may be performed at the engine start timing in a specific time zone of the day (for example, time 18:00 to 6:00).

That is, as shown in FIG. 26 (a), time 1
When the engine is started at time t4 in the time zone of 8:00 to 6:00 and a signal indicating that the engine has been started is input to the communication terminal 56, this signal is used as a trigger, as indicated by arrow i. Then, the current position of the mobile work machine 31 is captured in an electronic mail and transmitted to the communication satellite 9 as an electronic 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 manager side. Here, the time is from 18:00 to 6:00
The specific time zone (nighttime) is a time zone in which a mobile work machine such as a construction machine is not normally operating. Even more so, it is a time zone where people do not move for a long time. The fact that the engine is started and the mobile work machine 31 has moved during this specific time zone may cause some abnormality. Since the history of the position of the mobile work machine 31 in a specific time zone is displayed on the terminal on the administrator side, it is determined by monitoring this display screen that something has changed in the mobile work machine 31. be able to.

Also, automatic transmission from the mobile work machine 31
As shown in FIG. 26 (e), it may be performed at the timing of engine stop due to an abnormality.

Now, as shown in FIG. 2, the mobile work machine 31
An abnormality that occurred in, for example, "engine speed is high",
"Engine exhaust temperature is high", "Cooling water temperature is high", "Battery voltage is low", "Fuel amount is low"
Such an abnormality is detected by a predetermined sensor in the sensor group 62. As described above, the detection signal of this sensor is described as an error code (for example, “abnormal item: small fuel amount”) in the frame signal by the electronic control controller 53, and is sent to the signal line 52 to send the signal to the communication controller 5.
4 is input to the communication terminal 56. Communication terminal 5
A known technique other than this method may be used as long as the abnormality of the vehicle body can be monitored by 6.

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

[0314] Further, instead of automatically transmitting when an abnormality occurs, a specific abnormality item (severe abnormality item) is set in advance among abnormality items (error codes), and this serious abnormality occurs. The automatic transmission may be performed only in the case.

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

That is, as shown in FIG. 26 (a), time t
When the engine is started in 3, a start signal indicating that the engine has been started is input to the communication terminal 56. Here, the above error code is input to the communication terminal 56. When the service person or the like takes a predetermined action against the abnormality and the abnormality (fault) is eliminated, the error code is the communication terminal 5
No more input in 6. 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 when the error code is no longer input, it is determined that the abnormality (fault) has been resolved and the engine has been started, and this start signal is used as a trigger, as indicated by arrow h, The current position of the mobile work machine 31 is captured in an electronic mail and transmitted to the communication satellite 9 as an electronic mail. Therefore, similarly, the position of the mobile work machine 31 is displayed on the terminal on the manager side. According to the present embodiment, the position of the mobile work machine 31 is displayed on the terminal side only when the abnormality is eliminated and the engine is started, so that the position at the time when the abnormality is appropriately treated is accurately grasped. be able to.

Further, at a specific time (for example, time 23:00) from the mobile work machine 31, a specific mobile body information, for example, an operation map until the time 23:00 on the day (the engine is operated from what hour to what hour). Memory that indicates whether it was
May be automatically transmitted. As a result, as shown in FIG. 30, the daily operation map is displayed on the display screen on the terminal side.

Also, specific mobile unit information may be automatically transmitted from mobile work machine 31 at a specific time every few days (for example, every 2 days at 23:00).

From the mobile work machine 31, at a specific time for each specific day of the week (for example, 23:00 for each Saturday),
You may make it transmit specific mobile body information automatically.

Since the specific mobile body information is transmitted at the specific time as described above, the specific mobile body information of the mobile work machine 31 can be periodically acquired from the display screen on the terminal side.

When the cumulative value of the operating time of the mobile work machine 31 reaches a specific operating time cumulative value, for example, the absolute value of the service meter is 100 hours, 300 hours, 500.
When the time is reached, specific mobile unit information (for example, "service meter", "body alarm 1" (error code 1),
"Vehicle warning 2" (error code 2), "battery voltage", "engine water temperature", "engine speed", "pump pressure", "oil amount") may be automatically transmitted.

In this way, since the specific mobile unit information is transmitted when the specific accumulated operating time value is reached, it is possible to obtain the preliminary information for performing the legal regular inspection on the display screen of the terminal side. . Further, since automatic transmission is performed according to the change in operating time (load), it is possible to avoid wasteful communication while the vehicle is idle, and it is possible to suppress communication cost.

Also, every time the cumulative value of the operating time of the mobile work machine 31 increases by a specific amount, for example, every time the increase value of the service meter has passed 100 hours since the last automatic transmission (or 500 hours have passed). For each), specific mobile body information (for example, "service meter", "body alarm 1")
(Error code 1), "Body warning 2" (Error code 2), "Battery voltage", "Engine water temperature", "Engine speed", "Pump pressure", "Oil amount") may be automatically transmitted. . The increase value of the service meter can be set according to the patrol time by the service car 34.

As described above, since the specific mobile unit information is transmitted every time the cumulative operating time value increases by the specific amount, preliminary information for performing the legal regular inspection is acquired on the display screen of the terminal side. be able to. Further, when displayed on the terminal on the manager side, it is possible to easily give a patrol instruction to the service car 34. Further, when displayed on the terminal on the side of the service person, the mobile work machine requiring the service can be easily specified and the service car 34 can quickly provide the service. Further, since automatic transmission is performed according to the change in operating time (load), it is possible to avoid wasteful communication while the vehicle is idle, and it is possible to suppress communication cost.

Various modifications can be made to the above embodiment. Hereinafter, FIGS. 9, 10, 11, 12, and 14 will be described.

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.

Since position information is transmitted every time the position of the mobile work machine 31 changes in this way, the movement history of the mobile work machine 31 can be acquired on the display screen on the terminal side.

Further, the automatic transmission may be performed when the mobile work machine 31 deviates from the specific setting 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 this work site is the radius S (k
It is a circle of m). Therefore, the detected position of the mobile work machine 31 and the boundary position of the setting range 129 are compared to determine whether or not the mobile work machine 31 has deviated from the setting range 129. The mobile work machine 31 sets the boundary position J of the setting range 129.
When the time reaches, the position information of the mobile work machine 31 at that time 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, the mobile work machine 31 has the setting range 1
Since position information is transmitted at the time of deviation from 29 (at the time of exceeding 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 side. Can be done. Also, the setting range 129
Is not limited to a fixed range of work sites,
The range may be centered on the position where the mobile work machine 31 existed in the past. That is, the set range may be updated as time passes.

Further, 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 longitudinal direction in the traveling direction of the mobile work machine 31, a rectangle, etc.
It can have any shape.

The setting range 129 shown in FIG.
It may be a range corresponding to the normal range 117 shown in (a).

Further, 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 value between the position detected last time and the position detected this time, and the sampling time. Therefore, the moving speed V of the mobile work machine 31
And the set value V2 (FIG. 25) are compared, and it is determined whether or not the speed V of the mobile work machine 31 exceeds 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 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 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 runs 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 travel by itself, for example, a speed when the trailer 35 cruises on a highway, the speed V of the mobile work machine 31 is set to the set value V2. If it exceeds, it can be determined by the trailer 35 that it is being transported. Further, when the vehicle is transported by the trailer under a condition or time when the transportation is not normally performed, it can be recognized that an abnormal situation has occurred, and appropriate measures can be promptly taken.

The automatic transmission may be performed when the service car 34 enters the specific setting range 125, 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 intrusion prohibition area 125 in which is stored is stored. Setting range of this destination 126
Is a circle having a predetermined radius centered on the position of the mobile work machine 31. The intrusion prohibited area 125 is, for example, a road regulated due to heavy rain or an area with poor ground.

Then, the detected position of the service car 34 is compared with the boundary position of 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 the route 128 to set the range 125 or 12.
When the boundary position H or I of 6 is reached, 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.

In this way, the service car 34 sets the setting range 1
Since the position information is transmitted at the time of invading 25 or 126 (at the time of exceeding the set position), whether or not the service car 34 has arrived at the destination on the display screen of the terminal or the intrusion prohibited area is displayed. 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 arrives at the destination 126 and starts the service, and at the same time the service car 34 enters the intrusion prohibited area 125 and is in a dangerous state. Can be recognized. Therefore, as described above, it is possible to transmit appropriate work instruction data (message "return as soon as possible", "avoid intrusion prohibited area") to the service car 34 from the terminal on the administrator side (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 have 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 adopting a pay-as-you-go billing system, as shown in FIG. 11A, the communication charge paid once is a fixed amount per month up to a predetermined data amount Do.
When the data amount D exceeds the set value D0, it is necessary to pay an additional fee for the excess data amount.

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

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

Further, the automatic transmission may be performed when the fuel amount matches the set value or becomes less than the set value as shown in FIG. 12 (a).

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, as shown in FIG. 12A, when the detected fuel amount matches the set value,
The mobile body information (“position”, “fuel amount”) is transmitted to the communication terminal 56 as transmission data. Then, an electronic mail in which mobile body information is described is automatically transmitted from the communication terminal 56 via the satellite communication antenna 58.

As described above, since the mobile body information is transmitted when the fuel amount matches (or becomes less than or equal to) the set value, it is time to refuel from the display screen on the terminal side. You can recognize that. Therefore, similar to FIGS. 3 and 4, the terminal on the manager side can transmit appropriate work instruction data (message “refuel”) to the service car 34 performing the refueling patrol service.

Further, the automatic transmission may be performed when the voltage of the battery 63 matches the set value or becomes lower than the set value as shown in FIG. 12 (b).

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

In this way, when the voltage of the battery 63 matches the set value (or becomes less than the set value), the mobile body information is transmitted. Therefore, the battery 63 is charged and replaced from the display screen on the terminal side. It is possible to recognize when it is time to perform maintenance and inspections such as maintenance. Therefore, in the same manner as in FIGS. 3 and 4, the terminal on the administrator side can transmit the data of the appropriate work instruction (the message “check the battery”) to the service car 34. Further, by recognizing on the display screen of the terminal side that the battery 63 is in a state of near discharge, a request to turn on the sleep function is transmitted thereafter, and communication with the mobile work machine 31 is performed only intermittently. It can be set so that no further discharge can be suppressed.

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

As shown in FIG. 2, an abnormality occurred 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 in the sensor group 62. As described above, the detection signal of this sensor is described as an error code (for example, “abnormal item: small fuel amount”) in the frame signal by the electronic control controller 53, and is sent to the signal line 52 to be sequentially input to the communication controller 54. To be done.

The communication controller 54 compares the previously automatically transmitted error code with the currently input error code. Then, only when the previously automatically 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 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 transmitted. Since the automatic transmission is not performed when the error code has the same content, it is possible to avoid waste of transmitting the same information a plurality of times. The same applies when the mobile body information other than the error code is automatically transmitted.

Further, in the above-mentioned embodiment, when the parameter reaches a specific value inside the moving body, the specific moving body information is voluntarily transmitted.
(Memory data such as data amount D, sensor detection data such as battery voltage), "specific value", "specific mobile body information", for example, the terminal of the administrator side (server terminal 2
1. It is also possible to implement an arbitrary change from the terminal 11).
In this case, as described above, the e-mail in which the change data to the effect that the above parameters are changed is described from the terminal,
The mobile work machine 31 is transmitted to the mobile work machine 31 as an email address. And the mobile work machine 3 of the transmission destination
The change data described in the electronic mail is read by the first 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 certain user (there is no need for monitoring). In case of long-term suspension (when it is clear that the operation is stopped), the monitoring interval becomes longer and unnecessary parameters such as power consumption and communication charges are reduced. Value ”and“ specific mobile object information ”are changed. It should be noted that a plurality of moving bodies that are working and traveling in a group can be changed to the same content all at once. For example, “specific mobile body information” can be reduced to only important monitoring items.

As described above, according to this embodiment, it is possible to change the time and content of automatic transmission by remote operation on the terminal side while monitoring the state of the moving body and the surrounding state. For this reason, it is not necessary for the worker to go to each location of the moving bodies 31, 32, ... to perform the changing work, and the work load is significantly 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. You may.

Further, instead of automatically transmitting the voltage value of the battery 63 as mobile body information, the variation amount of the voltage of the battery 63 may be automatically transmitted.

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

As described above, according to the present embodiment, even if the terminal side does not perform the request input operation by itself, on the display screen of the terminal side,
It is possible to grasp the specific mobile body information when the specific parameter reaches the specific value. Therefore, an abnormal situation (for example, failure) that occurs in a mobile unit that cannot be constantly managed and monitored
Can be recognized, and the operating state of the moving body and the resting state 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. It is applicable to any communication system including at least two communication stations and performing communication between the two communication stations.

By the way, 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 huge amount of information, and only this important information is collectively displayed on a specific display screen. This makes it possible for the administrator to quickly make a decision and deal with an abnormal situation.

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

Although not shown in FIG. 2, the mobile work machine 3
A start lock circuit is incorporated in the vehicle body 50 of No. 1. This start lock circuit is composed of 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 the 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, by turning on the key switch 64, fuel is injected and the engine is started.

There are cases where the vehicle 31 moves by itself and cases where the vehicle 31 is loaded on a transport vehicle such as a trailer and moves. Here, it is assumed that the vehicle is loaded on a trailer and moved. The following processing can be similarly applied when the vehicle 31 moves by itself.

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

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 start lock Alternatively, the information indicating that the release has been made e) The information indicating that the communication between the vehicle 31 and the server terminal 21 has been interrupted f) The information indicating that the request to the vehicle 31 has not been fulfilled (for example, even when a start lock setting command is issued) Regardless of the information that the vehicle 31 has not been set to start lock), that is, the vehicle 31 automatically sends a call to the server terminal 2
When receiving the automatically transmitted mobile body information at 1, the server terminal 21 determines whether or not the mobile body information should be displayed on the "notification screen" of the home page.

[0372] Now, the vehicle 31 side is out of fixed time (time 17:00).
When the engine is started from 0 to 8:00), the information that "the engine of the vehicle 31 has been started" is automatically transmitted to the server terminal 21 by e-mail. Since this mobile body information is the specific information of b) above, it is determined that it should be displayed on the "notification screen", and the display content of the "notification screen" is updated.

Therefore, at the terminal 11 that manages the vehicle 31, W
When the WW 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 startup.

As shown in FIG. 34, the content "The vehicle had an engine start outside the fixed time" is "occurrence time",
It is displayed together with the content that specifies the "maker", "model", "model number", "machine number", and "ID" of the vehicle 31. From this display screen, the administrator can know that the vehicle 31 "has started the engine outside the fixed time", and can take prompt and appropriate measures against abnormal situations such as mischief.

The administrator can place the vehicle 31 in 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 electronic mail to the effect that the vehicle 31 is set to the start lock state is transmitted from the terminal 11 to the vehicle 31 side.

On the vehicle 31 side, when the communication terminal 56 receives the data to the effect that the starting lock is set, this data is received by the communication controller 5.
Taken in 4. As a result, the communication controller 54
Outputs a start lock setting command to the start lock circuit. Therefore, 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 of the vehicle 31 is not restarted.

The vehicle 31 side determines whether or not the start lock is set. When it is determined that the starting lock has been set on the vehicle 31 side, the information that "the starting lock has been set remotely on the vehicle 31" is automatically transmitted to the server terminal 21 by e-mail. Since this mobile body information is the specific information of d) above, 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 shown in FIG.
As shown in, the content "remotely locked" is displayed together with the content that specifies the "occurrence time", "maker", "model", "model number", "machine number", and "ID" of the vehicle 31. To be done. From this display screen, the administrator
Can be confirmed to be "remote start locked".

[0380] The server terminal 21 stores that the electronic mail to the effect that the vehicle 31 is set to the start lock setting state is transmitted. Therefore, even if a predetermined time has elapsed after the e-mail was transmitted to the vehicle 31, the information that "the start lock has been set remotely" has not been returned from the vehicle 31 by e-mail, and the server terminal 21
“Vehicle 31
The startup lock setting is not made in. " That is, it is determined that “the request for the vehicle 31 has not been achieved”. The cause is a cause on the vehicle 31 side such as a malfunction of the start lock circuit of the vehicle 31, or the vehicle 31 and the server terminal 21.
There are both possible causes for the poor communication status between and. Since this mobile body information or communication status information is the specific information of the above f), the "notification screen" is displayed on the server terminal 21.
The content displayed on the "Notification screen" is updated.

Therefore, the display screen of the terminal 11 is shown in FIG.
As shown in, the content "The confirmation of the lock has not arrived from the vehicle" identifies the "occurrence time", the "maker", "model", "model number", "machine number", and "ID" of the vehicle 31. Displayed along with the content. From this display screen, the administrator can know that "the lock has not been confirmed" on the vehicle 31. Then, it is possible to take prompt and appropriate measures against this abnormal situation.

The administrator can bring the vehicle 31 into the starting lock release state by remote control. This is executed by setting the display screen of the terminal 11 to the "engine restart cancellation screen" and clicking the "engine restart cancellation" button. As a result, an electronic mail to the effect that the vehicle 31 will be in the starting lock release state is transmitted from the terminal 11 to the vehicle 31 side.

On the vehicle 31 side, when the communication terminal 56 receives via the satellite communication antenna 58 the data indicating that the starting lock is released, this data is sent to the communication controller 5.
Taken in 4. As a result, the communication controller 54
Outputs a start lock release command to the start lock circuit. Therefore, 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.

On the vehicle 31 side, it is determined whether or not the starting lock has been released. When it is determined that the starting lock has been released on the vehicle 31 side, information that "the starting lock has been released remotely on the vehicle 31" is automatically transmitted to the server terminal 21 by e-mail. Since this mobile body information is the specific information of d) above, 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 content of “remotely unlocked” is displayed on the display screen of the terminal 11 as “occurrence time”, “maker”, “model”, “model number” of the vehicle 31,
It is displayed together with the content that specifies the "machine number" and "ID". From this display screen, the administrator can confirm that the vehicle 31 "remotely unlocks the starting lock".

[0386] The server terminal 21 stores that the electronic mail to the vehicle 31 to the effect that the starting lock is released is transmitted. Therefore, even if a predetermined time has elapsed after the e-mail was sent to the vehicle 31 side, if the information that "the start lock has been remotely released" is not returned from the vehicle 31 side by e-mail, the server terminal 21
"Vehicle 31
The starting lock has not been released. " That is, it is determined that “the request for the vehicle 31 has not been achieved”. The cause is a cause on the vehicle 31 side such as a malfunction of the start lock circuit of the vehicle 31, or the vehicle 31 and the server terminal 21.
There are both possible causes for the poor communication status between and. Since this mobile body information or communication status information is the specific information of the above f), the "notification screen" is displayed on the server terminal 21.
The content displayed on the "Notification screen" is updated.

[0387] Therefore, on the display screen of the terminal 11, the content "the confirmation of unlocking from the vehicle has not arrived" is "time of occurrence", "maker", "model", "model number", and "machine" of the vehicle 31. “No.” and “ID” are displayed together with the content to be specified. From this display screen, the administrator can know that "unlock confirmation has not been obtained" in the vehicle 31. Then, it is possible to take prompt and appropriate measures against this abnormal situation.

If the starting device operates even though the vehicle 31 is once in the start locked state, the vehicle 31
May automatically send a message to that effect. That is, information that "the vehicle has started even though the start lock has been set remotely" may be displayed on the "notification screen" of FIG.

By the way, the automatic transmission from the vehicle 31 is 2 every day.
It is supposed to be performed every 3:00. As shown in FIG. 30, the contents of the operation map are updated every day, and at 23:00 every day, the vehicle 31 of the updated operation map automatically transmits. Therefore, the state in which the transmission from the vehicle 31 has not continued for a predetermined time, for example, 36 hours or more means that the communication state is abnormal. This "36 hours" is the time obtained by adding the normal operating time (12 hours: 8:00 to 8:00 PM) of the next day to one day (24 hours).

The server terminal 21 stores the time when the vehicle 31 last sent an electronic mail to the server terminal 21. Therefore, if the untransmitted state continues for a predetermined time (36 hours) after the last transmission of the e-mail from the vehicle 31 side, the server terminal 21 determines that "the communication with the vehicle 31 has not been completed for 36 hours or more". It That is, vehicle 31
It is determined that communication between the server terminal 21 and the server terminal 21 is interrupted. This may be due to a failure on the communication device of the vehicle 31 such as a failure or damage on the vehicle 31 side or a cause of a poor communication state between the vehicle 31 and the server terminal 21.
Since the mobile body information or the communication state information is the specific information of the above e), it is determined that the server terminal 21 should display the "notification screen", and the display content of the "notification screen" is updated.

Therefore, the display screen of the terminal 11 is shown in FIG.
As shown in, the content of “not communicating with the vehicle for 36 hours or more” identifies the “occurrence time”, the “maker”, “model”, “model number”, “machine number”, and “ID” of the vehicle 31. Displayed along with the content. From this display screen, the administrator can know that "communication has been lost" with the vehicle 31. Then, it is possible to take prompt and appropriate measures against this abnormal situation.

In this embodiment, it is determined that the communication with the vehicle 31 has been interrupted by the absence of the next automatic transmission even after a lapse of a predetermined time from 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 side even if a predetermined time has elapsed after the input operation requesting information from the terminals 11, 12 ... May be.

By the way, as described above, the battery 6 of the vehicle 31
The voltage of 3 is detected by the sensor group 62 and the communication controller 5
4 is input. Battery 6 in communication controller 54
It is determined whether or not the voltage of 3 continues to fall below a predetermined level (for example, 23 V) (for example, 1 minute or more). The decrease in the voltage of the battery 63 means that not only the starting of the vehicle 31 becomes difficult but also the in-vehicle communication function is down, which is a serious abnormal situation. When the start lock circuit of the vehicle 31 is operated, electric power is consumed by the relay of the start lock circuit, so that the voltage of the battery 63 is easily lowered.

If it is determined that the voltage of battery 63 is continuously reduced to a predetermined level (for example, 23 V) or lower (for example, 1 minute or longer) on the side of vehicle 31, the server terminal 21 is informed that "the battery of vehicle 31 is Information that "voltage of 63 has dropped" is automatically transmitted by e-mail.
Since this mobile body information is the specific information of the above c), it is determined that the server terminal 21 should display it on the "notification screen", and the display content of the "notification screen" is updated.

Therefore, on the display screen of the terminal 11, the content "Battery voltage is low" indicates "occurrence time",
It is displayed together with the content that specifies 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. Then, it is possible to take prompt and appropriate measures against this abnormal situation.

As already described with reference to FIGS. 9 and 10, 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 setting range 129, it is automatically transmitted. The specific setting range 129 is set to, for example, a management area of the vehicle 31 (for example, “Tokyo”) or a movable range of the vehicle 31 (for example, “in Japan”). If it is out of the set range, it can be determined that an abnormal situation has occurred.

When it is determined that the vehicle 31 has deviated from the specific setting range 129, the information "vehicle 31 is out of range" is automatically transmitted to the server terminal 21 by electronic mail. Since this mobile body information is the specific information of a) above, it is determined that the server terminal 21 should display it on the "notification screen", and the display content of the "notification screen" is updated.

Therefore, on the display screen of the terminal 11, the content "vehicle is out of range" is "occurrence time", "maker", "model", "model number", "machine number", and "ID" of the vehicle 31.
Is displayed along with the content that specifies the. From this display screen, the administrator can know that the vehicle 31 "exists outside the range". Then, it is possible to take prompt and appropriate measures against this abnormal situation.

When the vehicle 31 is out of the specific setting range 129, an automatic call is made and the information "vehicle is out of range" is displayed on the "notification screen", but the vehicle 31 is in the specific setting range 129. You may make an automatic call when you enter and display the information "Vehicle is within range" 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" shown in FIG. 34 is displayed on the terminal 11
Not only is it displayed on the display screen in the other terminals 12 as well. As a result, the “notification screen” of FIG. 34 is displayed on the terminal 12 as well, and it is possible to easily confirm the important information generated by the previous day.

Also, it is possible to allow the display of the "notification screen" of FIG. 34 only on the display screen of the management terminal 11 that manages the vehicle 31 and not display the "notification screen" on the display screens of other terminals 12 and the like. It is possible. This is shown in FIG.
The display of the "notification screen" of No. 4 can be realized by the condition that the input operation of the specific ID number and the specific personal identification number (the number corresponding to the terminal 11) is performed.

In this embodiment, the "notification screen" shown in FIG.
The specific information to be displayed in (1) is not limited to the information shown in (a) to (f).

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

Further, when the vehicle 31 has moved a predetermined distance or more, the vehicle 31 may automatically make a transmission and display the information "moved a predetermined distance or more" on the "notification screen". This predetermined distance is set to, for example, a distance at which the vehicle 31 is not considered to move normally.

When an error code is input to the communication terminal 56 of the vehicle 31, the vehicle 31 may automatically make a call and the information indicating that the error has occurred may be displayed on the "notification screen". 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 in a) is displayed for the vehicle 3
For item 2, only the display item of b) can be displayed on the “notification screen”.

In this embodiment, the "notification screen" is displayed on the terminal 11 fixed at one place, but the contents of the "notification screen" can be displayed on the portable terminal.

[0408] For example, the contents of the "notification screen" can be displayed on a mobile phone equipped with a WWW browser.

[0409] In this case, the packet communication network of the mobile phone and the Internet 2 are connected by a gateway. Then, the gateway converts 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 on the server terminal 21, a voice message "new information has arrived" is generated on the mobile phone. As a result, the content of the newly updated "notification screen" is displayed on the display screen of the mobile phone. The display items of the "notification screen" to be displayed on the mobile phone may be limited to the specific display items of a) to f). For example, only the information b) "The engine of the vehicle 31 has been started outside the fixed time" can be displayed on the display screen of the mobile phone. As a result, even when the administrator is away from the terminal 11, it is possible to obtain the urgent information about the vehicle 31 in real time from the display screen of the mobile phone.

By the way, since construction machines are expensive, they are often provided for rental. The rental of construction machinery has a system called group rental. 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 construction machines of various types are shared by multiple sales offices. . For this reason, if a customer requests a rental of a specific model at a sales office and there is no construction machine of the corresponding model, another sales office can accommodate the construction machine of the specific model. Never miss an opportunity.

[0411] In order to meet the customer's request for rental, it is necessary to surely manage the loading and unloading of the construction machine at each business office. Next, an embodiment for managing warehousing and warehousing will be described.

FIG. 35 shows a configuration example of the embodiment.
FIG. 35 shows each of the business offices 130, 131 and 132 existing in an area 135 called “Tokyo”. It is assumed that the sales office 130 is in "West Tokyo", the sales office 131 is in "North Tokyo", and the sales office 132 is in "South Tokyo". 133 and 134 have shown the work site of a customer. Vehicles 31 and 32 are managed at business offices 130 to 132. Actually, sales office, work site, vehicle (moving work machine)
Are present, but are omitted for convenience of explanation.

13 of the offices 130, 131, 132
1 is the headquarters and 130 and 132 are branches. Headquarters 131
Manages vehicles 31, 32 in a centralized manner. Headquarters 131
A terminal 11 is provided in the. Branches 130 and 13
2 may be provided with a terminal equivalent to the terminal 11.

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

A storage area for each of the business offices 130, 131, 132 is set around the points P, Q, R. For example, the branch 130 has a storage area 13 centered on the point P.
0a is set. Further, a shipping area 130b centered on the point P is set. The shipping area 130b is larger than the shipping area 130a, and has a hysteresis of ΔX between the boundary line of the shipping area 130b and the boundary line of the shipping 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 loading / unloading area is determined in consideration of the error of the GPS measuring device, the size of the sales office, and the like. For example, the loading / unloading area has a width and width of several hundred meters.

Further, work areas 133 and 134 are set around the points Z and W for each work site 133 and 134.

The communication controller 54 of the vehicle 31 stores the position information of the loading / unloading areas of the business offices 130, 131, 132 and the position information of the work areas of the work sites 133, 134. Similarly, similar position information is stored in the communication controller 54 of the vehicle 32.

In order to newly mount the communication terminal 56 on the vehicles 31 and 32 and start communication, it is necessary to perform a communication application procedure and confirm the application receipt 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.

That is, after the communication terminal 56 is mounted on the vehicles 31 and 32, a communication application input operation is performed from the display screen of the terminal 11. As a result, the 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 business offices 130, 131, 132 and the position information of the work sites 133, 134 to the vehicles 31, 32. As a result, the communication controller 54 of the vehicles 31, 32 stores the position information of the loading / unloading areas of the business offices 130, 131, 132 and the position information of the work areas of the work sites 133, 134. When the communication connection is confirmed, the fact that the communication application for the vehicles 31, 32 has been received is displayed on the display screen of the terminal 11. After confirming the receipt of this application at terminal 11, vehicle 3
Communication is possible between the first and the second 32.

The operation when the vehicle 31 leaves the vehicle will be described below by representing the vehicle 31.

As described above with reference to FIGS. 9 and 10, the vehicle 3
The position of 1 is the GPS sensor 5 via the GPS antenna 59.
Detected at 7. 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 the sales offices 130, 131, 1
The position of the entry / exit area 32 is compared to determine whether the vehicle 31 has entered / exited from the entry / exit area.

For example, assume that vehicle 31 enters branch office 130.

The vehicle 31 is in the storage area 130 of the branch office 130.
Whether or not the vehicle 31 has entered the branch 130 is determined depending on whether or not the vehicle 31 has entered the inside from the outside of the a and remains inside the storage area 130a for a predetermined time (for example, a few minutes). The condition that the storage area 130a stays in the storage area 130a for a predetermined period of time or more is taken into consideration only when passing through the branch office 130. As a result, receiving area 1
When it is determined that the vehicle 30a has been entered, an identification code that identifies the vehicle 31 ("vehicle 31") at that time, an identification code that identifies the branch office 130 ("Nishi Tokyo store"), and an identification code that indicates "garbage" (These are referred to as “stock information”) are sent from the communication controller 54 to the communication terminal 56 as outgoing data. Then, from the communication terminal 56 to the satellite communication antenna 58
An electronic mail in which the above-mentioned storage information is described is automatically transmitted to the server terminal 21 via. Here, it is assumed that the server terminal 21 is provided at the location of the manufacturer of the vehicles 31, 32.

On the server terminal 21, a homepage display screen called "in / out screen" shown in FIG. 36 is created.

[0426] That is, when the vehicle 31 side makes an automatic call and the server terminal 21 receives the automatically received warehousing information, the server terminal 21 describes the warehousing information on the "I / O screen" of the homepage, The display content of "" is updated.

Therefore, at the terminal 11 that manages the vehicle 31, W
When the WW 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 “entry / unloading screen” showing the entry / exit history of the vehicle 31.

[0429] As shown in Fig. 36, the content that the vehicle 31 has been stored in the West Tokyo store is displayed in real time together with the "storage time". From this display screen, the administrator can know that the vehicle 31 is "stored in the West Tokyo store" and can make arrangements for the customer with certainty.

Similarly, the vehicle 31 deviates from the inside of the shipping area 130b of the branch office 130 to the outside and determines that the vehicle 31 stays outside the shipping area 130b for a predetermined time (for example, a few minutes). 31 is branch 1
It is determined that the product has been delivered from 30. Vehicle 3 at this point
The information that 1 has been issued from the "West Tokyo" branch 130 (this is called "delivery information") is automatically transmitted to the server terminal 21 by e-mail. Therefore, as shown in FIG. 36, the vehicle 3
The content "1" has been issued from the West Tokyo store is displayed in real time together with the "delivery time".

As described above, the shipping area 130b is as described above.
A hysteresis of ΔX is provided between the boundary line of the storage area 130a and the boundary line of the storage area 130a. Therefore, it is possible to prevent hunting when the vehicle 31 is moving near the branch office 130.

Similarly, when it is determined that the vehicle 31 has entered the storage area 132a of the branch office 132, the receipt information indicating that the vehicle 31 has arrived at the "South Tokyo" branch office 132 at that time is sent to the server terminal 21 by electronic mail. Will be automatically sent to. Therefore, as shown in FIG. 36, the content “Vehicle 31 has been stored in the South Tokyo store” is displayed in real time on the “storage / unload screen” of the display device of the terminal 11 together with the “storage time”.

Further, when it is determined that the vehicle 31 has left the delivery area 132b of the branch 132, the vehicle 31 is determined at that time.
Storage information indicating that the product has been delivered from the “Minami Tokyo” branch 132 is automatically transmitted to the server terminal 21 by electronic mail. For this reason, as shown in FIG. 36, the content of the vehicle 31 "has been exited from the Minami Tokyo store" is displayed in real time on the "in / out screen" of the display device of the terminal 11 together with the "outgoing time".

[0434] When the vehicle 31 enters the storage area 131a of the "North Tokyo" head office 131 or "North Tokyo" head office 1
Similarly, when the customer exits from the delivery area 131b of 31
On the "in / out screen" of the display device of the terminal 11, the content of the vehicle 31 "has been stored in the north Tokyo store" or "has been discharged from the north Tokyo store" is displayed.

Thus, as shown in FIG. 36, the vehicle 3
The latest history of entry and exit of item 1 is displayed in real time.
In addition, a similar "in / out screen" is obtained for vehicles 32 other than the vehicle 31, and the latest history of loading / unloading of the vehicle 31 is displayed in real time. Therefore, it is possible to reliably manage the loading and unloading of the vehicles 31 and 32 without error. As a result, business opportunities are not missed and operating revenue is dramatically improved.

When it is determined that the vehicle 31 has entered the work area 133 of the customer who is the rental destination, the carry-in 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. It is automatically sent. Therefore, on the display device of the terminal 11, the content that the vehicle 31 has been carried into the work site 133 is displayed in real time together with the “carry-in time”.

Further, when it is determined that the vehicle 31 has left the work area 133, the vehicle 31 is at that point in time.
The carry-out information that the product has been carried out from 33 is automatically transmitted to the server terminal 21 by electronic mail. Therefore, terminal 1
On the display device No. 1, 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 the work site 134 or leaves the work site 134,
On the display device of the terminal 11, the vehicle 31 displays “Work site 134
Has been carried in ”or“ has been carried out from the work site 134 ”. In this way, the loading / unloading history of the vehicle 31 is updated.

Further, the movement history of the vehicle 31 after leaving the warehouse from each of the business 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 with.

The current position of the vehicle 31 and the work site 133,
By comparing 134 known positions Z, W,
It is possible to determine on the screen of the terminal 11 whether or not the vehicle 31 is present at the work sites 133 and 134.

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 "notification screen" shown in FIG. As a result, the manager can know that the vehicle 31 "exists outside the management area" and can take prompt and appropriate measures against an abnormal situation.

The management terminal 1 for managing the vehicles 31, 32
It is also possible to allow only the display screen of No. 1 to display the "in / out screen" of FIG. 36 and not display the "in / out screen" on the display screens of terminals other than the terminal 11. This is realized, for example, by making the display of the "in / out screen" of FIG. 36 conditional on the input operation of a specific ID number and a specific personal identification number (a number corresponding to the terminal 11).

By the way, construction machines 31, 3 to the rental destination
Construction equipment 31, 32 from the second destination or rental destination
Is collected by mounting the construction machines 31, 32 by the trailer 35. Since the transportation cost by the trailer 35 is high, it is necessary to improve the transportation efficiency 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 to increase rental opportunities and increase operating income.

Next, referring to FIG. 37, the construction machines 31, 3
An embodiment capable of increasing the transportation efficiency of item 2 will be described.

As described with reference to FIG. 36, on the terminal 11 side, information on whether or not the vehicles 31 and 32 are in and out of the business offices 130 to 132 and the vehicles 31 and 32 at the work sites 133 and 134, respectively. It manages information on whether or not it is carried in or out.

Now, on the terminal 11 side, as shown in FIG. 37 (a), "the vehicle 31 has entered the branch office 130 and the work site 134
It is assumed that the loading / unloading information and the loading / unloading information "the vehicle 32 has been loaded into the vehicle." At this time, it is assumed that there is a request to "carry in the vehicle 31 to the work site 133 and carry out the vehicle 32 from the work site 134". Then, based on the above-mentioned loading / unloading information and loading / unloading information, terminal 1
From 1 to the trailer 35, "vehicle 31 of branch 130
To the work site 133 and return to the work site 134
The work instruction data of "carrying out the vehicle 32 and collecting it to the branch office 130" can be sent by e-mail. In this case, in the same way as already explained in FIG.
On the display screen of the terminal 14 installed, “current position of trailer 35 itself, current position of vehicle 31 (position of branch office 130), position of work site 133, current position of vehicle 32 (work site 13
Position 4) and 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 office 130, loads the vehicle 31 and leaves the branch office 130.
At this time, shipping information that the vehicle 31 has exited from the branch office 130 is automatically transmitted from the vehicle 31, and the contents of the "in / out screen" of FIG. 36 are updated. The trailer 35 carries the vehicle 31 and enters a work site 133 via a route 136. At this time, loading information that the vehicle 31 has entered the work site 133 is automatically transmitted from the vehicle 31 and the loading / unloading history is updated.

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 from the work site 134. Vehicle 3 at this time
Carry-out information that 2 has been carried out from the work site 134 is automatically transmitted from the vehicle 32, and the carry-in / carry-out history is updated.

The trailer 35 is equipped with the vehicle 32, and the route 1 is set.
38 to branch office 130. At this time, the warehousing information that the vehicle 32 has entered the branch office 130 is automatically transmitted from the vehicle 32, and the warehousing / leaving history regarding the vehicle 32 is updated.

As described above, the trailer 35 can carry in the vehicle 31, carry out the vehicle 32, and collect the vehicle 32 with a single movement. Therefore, the time during which the trailer 35 is in the empty state can be reduced, and the transportation efficiency is improved.

FIG. 37 (b) shows another example of transportation work.

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
Vehicles 31 and 32 have been unloaded from 0 and 132) ". At this time, it is assumed that there is a request to "carry the vehicle 31 into the work site 134 and carry out the vehicle 32 from the work site 134". Then, based on the above-mentioned loading / unloading information and loading / unloading information, “the vehicle 31 of the work site 133 is carried out to the work site 134 from the terminal 11 to the trailer 35.
And transfer the vehicle 32 at the work site 134 to the branch 1
The work instruction data "collect up to 32" can be sent by e-mail. In this case, as in the case already described with reference to FIG. 4, on the display screen of the terminal 14 equipped with the trailer 35, “current position of trailer 35 itself, current position of vehicle 31 (position of work site 133), current position of vehicle 32” is displayed. (Position of work site 134), position of branch office 132 and 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 through the route 139, loads the vehicle 31 and carries it out from the work site 133. At this time, unloading information that the vehicle 31 has been unloaded from the work site 133 is automatically transmitted from the vehicle 31 and the loading / unloading history is updated. The trailer 35 carries the vehicle 31 and enters a work site 134 via a 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 / carry-out history is updated.

[0454] The trailer 35 loads the vehicle 32 and carries it out from the work site 134. At this time, unloading information that the vehicle 32 has been unloaded from the work site 134 is automatically transmitted from the vehicle 32, and the loading / unloading history is updated.

The trailer 35 is equipped with the vehicle 32 and is route 1
Take branch 41 to branch office 132. At this time, the warehousing information that the vehicle 32 has entered the branch office 132 is automatically transmitted from the vehicle 32, and the warehousing / leaving history regarding the vehicle 32 is updated.

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

Note that in FIG. 37, the positions of the vehicles 31, 32 are
By comparing the work areas 133 and 134 having a certain size, the vehicles 31, 32 are
It is determined whether or not the data exists in 3,134. However, by comparing the current position of the vehicle 31 with the center positions Z and W of the work sites 133 and 134,
It may be determined whether or not No. 2 exists in the work sites 133 and 134.

In the above-described embodiment, the vehicle 31 is remotely set to the start lock setting state (hereinafter, start lock), and the vehicle 31 is remotely set to the start lock release state (hereinafter, start unlock). On the other hand, the construction machine 31 does not normally operate in a specific time zone (outside the fixed time 17:00 to 8:00).
If the engine of the construction machine 31 is started and operating during this time period, it is considered that an abnormality such as a mischief has occurred. However, the vehicle 31 is used for the terminal 11 at the same time every day.
It is troublesome to remotely lock and unlock the start by remote control.

[0459] Therefore, the data of a specific time zone is previously stored in the terminal 1
An embodiment will be described in which the transmission is performed from the first side to the vehicle 31 and the vehicle 31 itself enters the start lock state at the specific time zone and enters the start unlock state after the specific time zone elapses.

FIG. 38 is a flow chart 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 zone designation" button is clicked, a message for designating the "lock start time Ts" is displayed. In response to this, the content of the "lock start time Ts" is input, for example, "PM 17:00". As a result, the lock start time Ts of the vehicle 31 becomes “PM 17: 0
It is set to "0" (step 701).

[0462] Next, a message is displayed asking for "Lock end time Te" to be specified. In response to this, "Lock end time T
The content of “e” is input, for example, “AM 8:00”.
As a result, the lock end time Te of the vehicle 31 becomes "AM8:
00 "is set (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 side by electronic 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 acquired 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 lock end time Te (AM 8:00)
If the time is before the passage of time (steps 706 and 707)
Determination YES), the communication terminal 56 to the communication controller 5
A start lock setting command is output via 4 to the start lock circuit. Therefore, the relay of the start lock circuit is energized to enter 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) or the lock end time Te
If the time is after (AM 8:00) (step 706)
No., 707; NO), the communication terminal 56 outputs a start lock release command to the start lock circuit via the communication controller 54. For this reason, the relay of the starting lock circuit is deenergized to enter the starting unlocked state. That is, when the key switch 64 is turned on, fuel is injected and the vehicle 3
The first engine can be restarted (step 709).

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

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

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

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

[0471] First, the customer (user) uses the terminal 11 that manages the vehicle 31 for the period of use (for example, AM on March 3).
Apply for PM 8:00 from 8:00 to March 15 (step 801). Next, the vehicle 31 is delivered to the user (step 802). Note that steps 801, 802
The application and delivery procedure of can be done by communication on the Internet 2.

[0472] 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 message prompting to specify the "use start date and time Ds" is displayed. . In response to this, the content of the "use start date and time Ds" is input, for example, "March 3, AM 8:00". As a result, the use start date / time Ds of the vehicle 31 is set to "8:00 on March 3, 8:00" (step 80).
3).

[0473] Next, a message is displayed asking for "use end date and time De" to be specified. In response to this, "use end date and time De"
For example, the content of “March 15th PM 8:00” is input. As a result, the use end date De of the vehicle 31 is set to "March 15th PM 8:00" (step 80).
4).

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

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 acquired from the internal calendar and 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 has passed the use start date and time Ds (March 3 AM 8:00) and the use end date and time De (March 15 P
If the date and time is before M8: 00) (step 8)
If the determinations at 08 and 809 are YES), the communication terminal 56 outputs a start lock release command to the start lock circuit via the communication controller 54. For this reason, the relay of the starting lock circuit is deenergized to enter the starting unlocked state. 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).

Whether the current date and time Dn is before the use start date and time Ds (8:00 on March 3, 8:00) or the use end date and time De
If the time is after (PM 8:00 on March 15) (determination NO in step 808, determination NO in step 809), a start lock setting command is output from the communication terminal 56 to the start lock circuit via the communication controller 54. . Therefore, the relay of the start lock circuit is energized to enter 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)
When is finished, the use of the breach of contract is prohibited. Moreover, the vehicle 31 whose engine cannot be started is rented (Ds to De)
It is possible to collect at any time after the end (step 812).

39. In FIG. 39, in order to lock the start at the end of the year and the beginning of the year and unlock the start when the end of the year and the beginning of the year ends, the end of the year and the beginning of the year (Ds to De) are set in steps 803 and 804. Then, the content of step 810 may be "starting lock" and the content of step 811 may be "starting unlock". As a result, at the end of the year and the beginning of the year (Ds to De), the start lock state is set (step 8).
10) During the period other than the end of the year and the beginning of the year (Ds to De), the starting unlocked state is set (step 811).

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

By combining the embodiment of FIG. 39 and the embodiment of FIG. 37, it is possible to prevent the use of the contract violation after the end of the rental period and efficiently collect the rental after the end of the rental period. That is, FIG. 37 (a)
For example, 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 at the work site 134, it is in the starting lock state after the rental period (Ds to De) is over, so the customer cannot use the contract in violation.
Then, when it is time to bring the vehicle 31 to another work site 133, the trailer 35 moves the vehicle 3 to the work site 133.
Carrying in 1 and carrying out and collecting the vehicle 32 left at the work site 134 are performed at the same time. Thereby, the recovery work after the rental period of the vehicle 32 is efficiently performed.

In this embodiment, a construction machine is mainly assumed as the vehicle 31. In a construction machine, the engine cannot be restarted, so that the revolving structure and the working machine cannot operate. Therefore, by setting the starting lock state, it is possible to avoid the risk of the working machine and the swing structure being inadvertently operated. That is, the present embodiment can be applied not only to the prevention of illegal use after the lapse of the rental period but also to the safety measure such as malfunction prevention. For example, if the operating lever for the working machine of the construction machine 31 is mistakenly operated by a person (for example, an elementary school student) who is not very skilled at operating the working machine, the working machine is inadvertently operated and becomes in a dangerous state. According to the present embodiment, it is possible to prevent an erroneous operation in which the working machine is inadvertently operated by setting the starting lock state.

In the embodiment, each vehicle 31, 32, 33 ...
It is assumed that the data communication between the server terminal 21 and the server terminal 21 is performed via the wireless communication 5 by the communication satellite 9. However, this communication method is an example, and any communication method can be adopted. That is, the existing ground wave may be used instead of the satellite communication. Also, communication may be performed using an existing telephone line. In addition, existing mobile base stations and P
Communication may be performed via the HS base station.

Especially when the vehicle is a construction machine, it may be considered to work underground. In this case, when data communication is performed using existing satellite communication equipment, communication failure occurs.

Therefore, an underground construction machine (for example, a vehicle 3
It is also possible to newly install a relay station that secures communication between 1) and the ground communication satellite 9 and perform data communication via this relay station.

It is also possible to provide two or more communication lines between the vehicles 31, 32, 33 ... And the server terminal 21 in a redundant manner. By thus providing the communication lines redundantly, it is possible to extremely reduce the probability that the communication is determined to be impossible.

By the way, as described above, even if the relay of the start lock circuit of the vehicle 31 is energized to cut off the starter signal and put in the start lock state, as long as it is familiar to the mechanism of the vehicle, electric It is possible to output a starter signal and start the engine by forcibly making a specific connection.

Therefore, an embodiment capable of coping with an abnormal situation in which the engine is actually started despite the start locked state will be described.

(Embodiment 1) FIG. 42 is a diagram corresponding to FIG. 2 and shows a structural example of a vehicle 31.

In the first embodiment, it is assumed that the vehicle 31 is a construction machine such as a hydraulic excavator equipped with the working machine 802 or a wheel loader. The construction machine may include a dump truck or the like as long as it has a plurality of controllers in the vehicle body.

In the embodiment, in the vehicle body 50 of the construction machine 31,
A plurality of controllers, that is, a monitor controller 81
It is assumed that the information management controller 812, the valve controller 813, the pump controller 814, the engine controller 815, and the communication controller 54 (see FIG. 2) are provided. The controllers 811, 812, 813, 814, 815 are connected to each other by a serial communication line 52 that performs communication according to a predetermined communication protocol.

The construction machine 31 is equipped with a working machine 802 including an arm, a bucket and the like.

The working machine 802 is connected to the hydraulic cylinder 803. Each cylinder chamber of the hydraulic cylinder 803 is connected to the directional flow control valve 804 via hydraulic piping. The direction in which the pressure oil is supplied to each cylinder chamber of the hydraulic cylinder 803 and the flow rate of the pressure oil supplied to the cylinder chamber are changed by the operation of the directional flow control valve 804.

The operation of the directional flow control valve 804 is controlled by the valve controller 813.

The directional flow control valve 804 is the hydraulic pump 8
05 through a pump discharge line. The capacity of the hydraulic pump 805 changes according to the tilt position of the swash plate.
The swash plate of the hydraulic pump 805 changes as the swash plate control unit 6 operates.

The operation of the swash plate controller 806 is controlled by the pump controller 814.

The hydraulic pump 805 is driven by the engine 816.

Fuel injection amount (torque) of the engine 816,
The engine speed and the like are controlled by the engine controller 815.

When the swash plate controller 806 is controlled by the pump controller 814, the tilt position of the swash plate of the hydraulic pump 805 changes, the capacity of the hydraulic pump 805 changes, and the directional flow control valve 804 is supplied. Pump discharge flow rate changes.

When the directional control valve 804 is controlled by the valve controller 813, the hydraulic cylinder 803
The direction and flow rate of the pressure oil supplied to each of the cylinder chambers change, and the drive direction and drive speed of the hydraulic cylinder 803 change. This changes the operating direction and operating speed of the work implement 802.

In each part of the vehicle body 50 of the construction machine 31, engine speed, battery voltage, fuel amount, engine oil pressure, engine oil temperature, hydraulic oil temperature, cooling water temperature, charging voltage for the battery 63 of the alternator (generator). Each sensor for detecting is arranged, and each sensor constitutes a sensor group 62. The sensor 62a is the battery 6 of the alternator.
It is detected that the engine 816 has actually started by detecting that the charging voltage to 3 has reached a certain level or higher.

The monitor controller 811 is built in the monitor panel 820. The monitor panel 820 is provided in the operator's cab of the construction machine 31.

On the outer surface of the monitor panel 820, an operation switch group 822 including a display screen 821 and each operation switch is provided.
And are arranged.

The monitor controller 811 includes the sensor group 6
The sensor detection value detected in 2 is collected, and when the sensor detection value reaches the abnormal value, the caution lamp is turned on on the display screen 821 or an error code is generated. Then, the monitor controller 811 displays an error code indicating the current state of the construction machine such as cooling water temperature and a specific abnormal state of the construction machine 31 such as engine oil pressure drop on the display screen 821 of the monitor panel 8210.

By operating the operation switch group 822 of the monitor panel 820, the monitor controller 811 generates control data for controlling the traveling device of the construction machine 31 and the working machine 802. The control data is output from the monitor controller 811 to the serial communication line 52. For example, by operating one of the setting switches of the operation switch group 822, the relationship between the operation amount of the work implement operation lever and the operation amount of the work implement 802, that is, the work mode, is set as “heavy excavation” or “excavation”. , “Adjustment”, or “fine operation” can be set.

Operation switch group 82 of monitor panel 820
2 includes a "start lock" switch 822a.

Engine key switch 64 (see FIG. 21)
Is turned off and the start lock switch 82a is operated, the start lock setting command signal LON is sent to the start lock circuit 8
To the start lock circuit 830, and the construction machine 31 enters the start lock state. That is, even if the engine key switch 64 is turned on, the starter signal is not output and the engine 816 cannot be started.

The release of the starting lock state is made on condition that the password (password) is input.

Operation switch group 82 of monitor panel 820
2 includes a password setting switch 822b for setting a password. Password setting switch 82
2b is configured as a ten-key switch, for example.

When the engine key switch 64 is turned off,
When the password setting switch 822b is operated, a password corresponding to the operation content is stored as a "setting password" in the memory in the monitor controller 811.

[0510] Operation switch group 82 of monitor panel 820
2 includes a password input switch 822c for inputting a password.

When the engine key switch 64 is turned on,
When the password input switch 822c is operated, the password corresponding to the operation content is input to the monitor controller 811, and the monitor controller 811 is input.
The CPU therein determines whether or not the input password matches the set password stored in the memory in the monitor controller 811. As a result, when the entered password matches the set password, the start lock release command signal LOFF is set to the start lock circuit 8
It is output to 30, and the construction machine 31 enters the starting lock release state. That is, by turning on the engine key switch 64, a starter signal is output and the engine 816 is started.

However, if the entered password does not match the set password, the start lock release command signal L
OFF is not output. Therefore, the start lock state of the construction machine 31 is maintained, and even if the engine key switch 64 is turned on, the starter signal is not output and the engine 816 cannot be started.

The above-mentioned start lock setting and start lock release can also be performed by remote operation from the terminal 11 provided on the administrator side.

In the first embodiment shown in FIG. 42, communication is performed via the terrestrial base station 817 instead of the communication satellite 9 shown in FIG. The terrestrial base station 817 is, for example, a mobile base station.

That is, the communication controller 54 of the construction machine 31 incorporates a communication terminal 56 for packet data communication. Wireless communication by packet communication between the antenna 808 of the communication terminal 56 and the terrestrial base station 817 5
Is done. The terrestrial base station 817 constitutes a part of the packet communication network. The packet communication network is connected to the Internet 2 shown in FIG. 1 via a gateway and a private line. The gateway performs protocol conversion between the packet communication protocol and the TCP / IP protocol of the Internet 2, and the existing "Internet connection service" can be used.

[0516] Therefore, when the operation of inputting the "starting lock setting" data is performed on the terminal 11 connected to the Internet 2, the starting lock setting command is issued to the ground wave base station 81.
7 is transmitted to the antenna 80 by the wireless communication 5.
8 is received by the communication terminal 56. When the communication terminal 56 receives the start lock setting command, the communication controller 54 outputs the start lock setting command signal LON to the start lock circuit 830. As a result, the relay of the start lock circuit 830 is energized, and the construction machine 31 enters the start lock state. That is, even if the engine key switch 64 is turned on, the starter signal is not output and the engine 816 cannot be started.

[0517] Further, when an operation of inputting "starting lock release" data is performed on the terminal 11, a starting lock release command is transmitted to the terrestrial base station 817, and the wireless communication 5
Is received by the communication terminal 56 via the antenna 808. When the communication terminal 56 receives the start lock release command, the communication controller 54 outputs the start lock release command signal LOFF to the start lock circuit 830. As a result, the construction machine 31 enters the start lock release state. That is, by turning on the engine key switch 64, a starter signal is output and the engine 816 is started.

The information management controller 812 collects the sensor detection values detected by the sensor group 62, and generates an error code when the sensor detection values have reached an abnormal value. Then, the information management controller 12 stores the sensor detection value and the error code in the internal memory. In this case, the time when the error code is generated is measured by the real-time clock IC and the oscillator, and the error code is associated with the time and then stored in the memory. As a result, it is possible to manage the time-series history of error codes generated in the construction machine 31.

A frame signal of a predetermined communication protocol is transmitted on the serial communication line 52. The frame signal is the controller 811, 812, 813, 814, 81.
5, 54, 54, each controller 811, 812, 813, 8 according to the data described in the frame signal.
A drive signal is output to the control target connected to 14, 815, 54, and each control target is drive-controlled.

For example, when the "heavy excavation" mode indicating a heavy work is set as the work mode by the operation switch group 822 of the monitor panel 820, the control data indicating the "heavy excavation" mode is described in the frame signal. Then, it is transmitted from the monitor controller 811 to the engine controller 815 via the serial communication line 52.

Therefore, the engine controller 815 receives the frame signal and reads the described control data indicating the "heavy excavation mode". Then, the engine 816 is controlled so that the fuel injection amount and the target rotation speed correspond to the "heavy excavation mode".

The case where data is transferred between the monitor controller 811 and the engine controller 815 by the frame signal has been described above. Data is similarly exchanged between the other controllers by the frame signal.

[Start lock setting] on the monitor panel 811
When the operation is performed (when the start lock setting signal LON is output), the data indicating the “start lock setting” is transmitted to the communication controller 54 via the serial communication line 52.

In the CPU of the communication controller 54, the serial communication line 52 is transferred from the monitor controller 811.
Based on the data sent via the communication terminal 56 and the data received by the communication terminal 56,
It is determined whether or not the start lock setting signal LON is output to the start lock circuit 830 from any of the communication controllers 54.

The information management controller 812 also takes in the detection value of the sensor 62a and transmits the detection value of the sensor 62a to the communication controller 54 via the serial communication line 52.

In the CPU of the communication controller 54, from the information management controller 812 to the serial communication line 5
Engine 81 based on the data sent via
6. Determine if 6 is actually starting.

As a result of these judgments, the start lock setting signal L
When it is determined that ON is output and the engine 816 is actually started (the engine 816 is operating), the communication controller 54 sets the “engine stall mode”, The control data indicating the "engine stall mode" is described in the frame signal and transmitted from the communication controller 54 to the engine controller 815 via the serial communication line 52.

Therefore, the engine controller 815 receives the frame signal and reads the described control data indicating the "engine stall". Then, the engine 816 is controlled so that the fuel injection amount corresponds to the "engine stall mode". The “engine stall mode” is a control mode in which the fuel injection amount for the engine 816 is cut or narrowed to the minimum. The "engine stall mode" has priority over the control mode such as the "heavy excavation mode" which is operated and set on the monitor panel 820.

For this reason, the engine 816 is stopped or operates with the minimum torque, so that the running and working cannot be performed, or the running and working performance is extremely lowered.

As described above, according to the first embodiment, when the engine 816 is actually started even though the construction machine 31 is put into the start lock state by the operation of the operator or the remote operation of the administrator. In addition, by stopping the engine 816, traveling and work can be made impossible. Alternatively, by operating the engine 816 with the minimum torque, the performance of traveling and work can be extremely lowered. As a result, it is possible to take prompt and appropriate measures against an abnormal situation of the construction machine 31.

[0531] In the first embodiment, the communication controller 56 determines whether or not to set and output the "stalling mode", but the monitor controller 811 may determine this. Alternatively, it may be performed by the information management controller 812.

[0532] Also, in the first embodiment, "engine stall mode"
As an example, the fuel injection amount to the engine 816 is cut or narrowed down to the minimum. However, this is an example, and the contents of the “engine stall mode” are that the running and working of the construction machine 31 are impossible. It may be possible to put it into a state or to put it in a state where the performance of traveling and work is extremely lowered. Less than,
Each example is given.

(Embodiment 2) The communication controller 54 outputs the start lock setting signal LON to the start lock circuit 830, and the engine 816 is actually started (the engine 816 is operating). When it is determined that the state is the state, the "stalling mode" is set, the control data indicating the "stalling mode" is described in the frame signal, and the communication controller 54 causes the pump controller 8 to operate.
14 through the serial communication line 52.

Therefore, the pump controller 814 receives the frame signal and reads the described control data indicating the "stalling mode". Then, the swash plate control unit 806 is controlled so as to reach the swash plate tilting position corresponding to the "engine stall mode". The “engine stall mode” is a control mode in which the swash plate of the hydraulic pump 805 is set to the maximum tilt position and the capacity of the hydraulic pump 805 is maximized. This "engine mode" is operated on the monitor panel 820,
Overrides the set control modes.

As a result, the load on the engine 816 becomes large, and it becomes impossible to run or work.
The work performance is extremely degraded.

(Third Embodiment) The communication controller 54 outputs the start lock setting signal LON to the start lock circuit 830 and the engine 816 is actually started (the engine 816 is operating). When it is judged that the state is the state, the "stalling mode" is set, the control data indicating the "stalling mode" is described in the frame signal, and the communication controller 54 causes the valve controller 8 to operate.
13 through the serial communication line 52.

For this reason, the valve controller 813 receives the frame signal and reads the described control data indicating the "stalling mode". Then, the directional control valve 804 is controlled so that the valve position corresponds to the "engine stall mode". The “engine stall mode” is a control mode in which the valve position of the direction control valve 804 is set to the neutral position or the minimum opening position. This "enst mode" is
Various control modes set and operated on the monitor panel 820 are given priority.

Therefore, the pressure oil is not supplied to each cylinder chamber of the hydraulic cylinder 803 or the minimum flow rate is supplied, so that the driving of the hydraulic cylinder 803 is stopped or the driving speed is minimized. As a result, the work of the construction machine 31 becomes impossible, or the work performance is extremely lowered.

FIG. 42 shows the hydraulic cylinder 8 for the working machine.
03, the directional flow control valve 804 for the working machine is shown, but instead of this, a hydraulic motor for traveling or a directional flow control valve for traveling may be used. In this case, the traveling of the construction machine 31 It becomes impossible or the driving performance is extremely deteriorated.

Further, the relationship between the operation amount of the operating lever for the working machine and the operating amount of the working machine 802 may be set to the "engine stall mode".

That is, the valve controller 813 controls the valve position of the directional flow control valve 804 so that the drive speed change amount of the hydraulic cylinder 803 per unit operation amount of the working machine operation lever becomes extremely small. Therefore, even if the operating lever for the working machine is operated to the full lever stroke, the working machine 802 can operate only at an extremely low speed, and the working performance is extremely lowered.

Similarly, the valve controller 813 controls the valve position of the directional flow control valve by controlling the valve position of the directional flow control valve so that the change amount of the drive speed of the hydraulic motor per unit operation amount of the traveling operation lever becomes extremely small. The traveling industry performance may be lowered.

(Fourth Embodiment) The communication controller 54 outputs the start lock setting signal LON to the start lock circuit 830, and the engine 816 is actually started (the engine 816 is operating). If it is determined that the engine is in the state, the "engine stall mode" is set, the control data indicating the "engine stall mode" is described in the frame signal, and the communication controller 54 causes the engine controller 815 or the pump controller 814 or the valve to operate. To controller 813 for serial communication line 52
To make the traveling or work of the construction machine 31 impossible, or bring the traveling performance or the work performance to an extremely low level (Example 1, Example 2, and Example 3).

The communication controller 54 further prepares data indicating that the "engine stall mode" is currently entered, and sends this data to the communication terminal 56. The communication terminal 56 sends this data from the antenna 808 to the terrestrial base station 8 by wireless communication 5.
Send to 17. That is, the construction machine 31 is triggered by the fact that the “engine stall mode” has been entered, and automatically transmits data to that effect. In addition, in this automatically transmitted data,
Data identifying the own vehicle 31 (source address)
It is included. For this reason, on the display screen of the terminal 11 connected to the Internet 2, the information "entered the stalled mode" is the data that identifies the construction machine 31 ("maker", "model", "machine number", "ID"). Is displayed together with. The information that "entered the engine stall mode" is shown in Fig. 3.
It can be included in the information in the "notification screen" shown in FIG.

As a result, the administrator on the terminal 11 side is shown in FIG.
The position of the construction machine 31 can be confirmed by switching to the “map display screen” shown in FIG. Furthermore, an appropriate person can be dispatched to the location of the construction machine 31. In this way, it is possible to take prompt and appropriate measures against an abnormal situation of the construction machine 31.

Further, when the server terminal 21 receives the data "entering the stalled mode", it is possible to take immediate measures against the abnormal situation.

(Embodiment 5) The communication controller 54 outputs the start lock setting signal LON to the start lock circuit 830, and the engine 816 is actually started (the engine 816 is operating). When it is determined that the state is in the state, data "starting lock and engine starting state" is created and this data is sent to the communication terminal 56.
The communication terminal 56 transmits this data from the antenna 808 to the terrestrial base station 817 by wireless communication 5. That is, the construction machine 31 triggers the judgment that "the engine is in the starting locked state and the engine is in the starting state", and automatically transmits the data to that effect.
Therefore, on the display screen of the terminal 11 connected to the Internet 2, the information "starting locked and engine starting state" identifies the construction machine 31 ("maker",
It is displayed together with "model", "machine number", "ID").
The information "starting lock and engine starting state" is
It can be included in the information in the "notification screen" shown in FIG.

As a result, the administrator on the terminal 11 side is shown in FIG.
The position of the construction machine 31 can be confirmed by switching to the “map display screen” shown in FIG. Furthermore, an appropriate person can be dispatched to the location of the construction machine 31. In this way, it is possible to take prompt and appropriate measures against an abnormal situation of the construction machine 31.

Further, when the server terminal 21 receives the data "starting locked and engine starting state", measures may be taken immediately against an abnormal situation.

[0550] Further, the administrator on the terminal 11 side confirms the information "starting lock and engine starting state", and then
The operation of inputting the data of “engine mode setting” may be performed on the terminal 11. When the operation of inputting the data of "enstal mode setting" is performed on the terminal 11,
The stalling mode setting command is transmitted to the terrestrial base station 817, and is received by the communication terminal 56 via the antenna 808 by the wireless communication 5. When the communication terminal 56 receives the stalling mode setting command, the communication controller 54
Describes the control data indicating the "engine stall mode" in the frame signal, and the communication controller 54 causes the engine controller 815 or the pump controller 8 to operate.
14 or the valve controller 813 via the serial communication line 52. As a result, as described in the first to third embodiments described above, the construction machine 31 becomes unable to run or work, or the running performance or work performance is extremely lowered.

In each of the first to fifth embodiments described above, the start of the engine 816 is detected by detecting that the charging voltage of the battery 63 of the alternator has risen above a certain level. However, this is an example, and any type of sensor can be used as long as it can detect that the engine has started, such as a sensor that detects engine speed, engine oil pressure, and engine cooling water temperature. However, a sensor that can detect with good responsiveness at the moment when the engine 816 starts is more preferable.

In the case of the construction machine 31, if the engine 816 stops while operating the operating lever for work machine or the operating lever for travel, the working machine 802 may drop or the vehicle body may drop due to gravity ( While climbing a slope), it becomes dangerous.

In this respect, according to the above-described first embodiment, the sensor 62a can detect the engine start with high responsiveness, and the engine can be quickly entered into the engine stall mode by high-speed in-vehicle communication. The engine 816 can be stopped (or the performance thereof can be lowered) at the moment when the engine 816 is started without operating the lever. Therefore, the construction machine 31 can be safely put in the stalled mode.

By the way, the labor management and work process management of the operator are important for the manager of the company who undertakes the civil engineering construction work and has the operator operate the construction machine to perform the civil engineering construction work. Therefore, the operator is obliged to create a daily work report. However, conventionally, since the work of reading and inputting the value of the service meter is forced, the work of creating the daily work report is troublesome and imposes a heavy burden on the operator. Further, since the input work is a manual work, an incorrect daily work report may be created due to an input error or the like.

[0555] The daily work report is useful information not only for a construction company who is a user of a construction machine, but also for a rental company that rents a construction machine, a used dealer that sells a used construction machine, and a manufacturer that manufactures a construction machine. Is. That is, for the rental company, by grasping the history of the daily work report, it is possible to discriminate between customers who use the product severely and those who do not, and it is possible to use it for customer management. Also, for used dealers who sell used construction machinery, by grasping the history of daily work reports, it is possible to calculate the past usage time and operating rate of construction machinery, which can be useful in setting the price of used cars. . Further, for the manufacturer of the construction machine, the durability of the construction machine can be calculated by grasping the history of the daily work report, which can be useful for designing the next model.

To this end, it is necessary to make it possible to easily obtain daily work report information from each terminal in real time.

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

The server terminal 21 is a terminal provided in the manufacturer, and a homepage display screen called "work daily report screen" shown in FIG. 40 is created.

When the vehicle 31 arrives every day at 23:00, the operation map, date, and operation time (FIG. 40) up to the time 23:00 on that day are automatically transmitted. Here, the operation map means that the output of the service meter provided in the vehicle 31 (whether or not the engine is operating) is compared with the output of the calendar and the timer provided in the vehicle 31 at each time, and the engine is operated. It is a table that shows the time zone in which it is operating.
The time zone filled with black in FIG. 40 corresponds to the time zone when the engine of the vehicle 31 is operating. The operating time is the cumulative value of the service meter per day (the operating time of the engine per day).

That is, the "operation map" automatically transmitted from the vehicle 31 side and transmitted automatically by the server terminal 21.
When the mobile body information such as "date" and "operating time" is received, the server terminal 21 updates the "work daily report screen" of the homepage with the mobile body information.

Therefore, when the WWW browser is activated on the terminal 11, the homepage 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. .

Therefore, as shown in FIG. 40, the "date", "operation map", and "operation time" of the vehicle 31 are updated and displayed with the latest data. The "Work daily report screen" shows the "Customer name" using the vehicle 31.
(ABC Civil Engineering Co., Ltd.), “work site name” where the vehicle 31 is operating (Iroha crushed stone site), “worker name” for each day, and “special notes” such as maintenance are also displayed. Note that the “customer name”, “work site name”, “worker name”, and “special notes” can be entered through communication on the Internet 2. When the "customer name", "work site name", "worker name", and "special note" are entered on the customer terminal, the input data is transmitted to the server terminal 21 via the Internet 2 and according to the input data. The contents of the "Daily work report screen" are updated.

[0563] As described above, the latest daily work report is sent to the terminal 1
It is displayed on the display screen of No. 1 in real time and can be easily obtained from the display screen of the terminal 11. That is, the daily work report is accurately created without imposing a burden on the operator. This allows the construction company to accurately perform labor management and work schedule management.

When the terminal 11 is provided in the rental company, the history of the daily work report can be grasped from the display screen of the terminal 11, and it is possible to discriminate between customers who use the product severely and those who do not. This can be useful for customer management. For example, it can make a decision not to warn a customer who makes heavy use of it or disallow rental. Further, by grasping the history of the daily work report, it is possible to find a customer who is hardly operating the vehicle 31 and advise the customer of the return. Further, by grasping the history of the daily work report, it is possible to predict when the vehicle 31 will be maintained.

When the terminal 11 is provided by a second-hand dealer that sells used construction machines, the history of daily work reports can be grasped from the display screen of the terminal 11, and the past usage time and operating rate of the construction machine can be grasped. Etc. can be calculated. This allows the used car price to be set appropriately.

When the terminal 11 is provided in a maker that manufactures construction machines, the history of daily work reports 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.

Further, 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 of FIG. 41 is the date and time, and the vertical axis is the cumulative value of the engine operating time measured by the service meter. Figure 4
From the graph of No. 1, it is possible to predict the maintenance period such as the periodic inspection period.

40 and 41 are allowed only on the display screen of the terminal 11 which manages the vehicle 31, and FIG. 40 and FIG. 41 are not displayed on the display screens of terminals other than the terminal 11. It is possible. This is, for example, shown in FIGS.
The display of 1 is a specific ID number, a specific personal identification number (terminal 1
It is realized by the condition that the input operation of (the number corresponding to 1) is performed.

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

By the way, when renting the construction machine 31, it is general to set a fee according to the length of the rental period and rent it. However, even with a rental period of the same length, with 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 amount may be automatically calculated according to the length of the engine operating time.

[0572] That is, the server terminal 21 receives the data "operating time" automatically transmitted from the vehicle 31, and performs the arithmetic processing for accumulating the operating time up to the present. On the other hand, the correspondence between the cumulative value of operating hours and the charge amount is preset. Therefore, the charge amount corresponding to the accumulated value of the operating hours up to the present is calculated from this correspondence. The server terminal 21 performs a process of updating the "work daily report screen" of the home page with the latest charge amount.

Therefore, when the WWW browser is activated on the terminal 11, the homepage 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 21st to January 30th. In the "Daily work report screen" of Fig. 40, the cumulative value of operating hours during the rental period (January 21st to January 30th), that is, the value obtained by summing up the daily "operating hours" during the rental period (49 hours 6 minutes) ), The charge amount XXXXXXXXX yen is displayed. As a result, the customer can easily obtain the information on the charge amount corresponding to the time the engine operates during the rental period on the screen in real time.

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

However, in reality, the demand for construction machinery varies greatly depending on the time. Specifically, the demand for construction machinery will increase during the period when construction is concentrated. In addition, demand is greater during the daytime than during nighttime. Therefore, the charge amount may be set according to the demand of the construction machine. Specifically, since the demand for construction machinery increases when construction is concentrated, the billing amount can be set higher, and conversely, the billing amount can be set lower during the off season. Further, the charge amount can be set high during the daytime and set low during the nighttime. Therefore, the billing amount can be determined in consideration of not only the accumulated value of operating hours but also the operating period, operating hours, and operating time.

Although the communication means 1 including the Internet 2 is assumed in the present embodiment described above, the communication means 1 of the present invention is not limited to this, and a communication means not including the Internet 2 may be used. It is also possible to build. In short, if the same communication as that described in the embodiment is performed, it can be replaced with another communication means. Further, in the present embodiment, the communication means 1 in which the wireless communication and the wired communication are combined is assumed, but of course, only the wireless communication may be performed, or only the wired communication may be performed.

Furthermore, in the present embodiment, the presentation format is assumed in which the mobile body information is displayed on the terminal as image data, but the present invention presents the mobile body information by outputting it as voice to the terminal. Alternatively, it may be printed out as print data by the terminal. In short, the presentation format of the mobile body information at the terminal is arbitrary.

[0578] In the present embodiment, it is assumed that a plurality of moving bodies including construction machines are mainly 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.
