When the accident occurrence of the vehicle is detected together with the current position of the vehicle, the wireless communication device installed in the vehicle notifies the center of the accident occurrence notification along with the current position, and the center requests the emergency car to be dispatched. The emergency vehicle calculates the travel time to the vehicle based on the current position information, and communicates the dispatch information of the emergency vehicle to the vehicle along with the calculation result, and the normal vehicle is equipped with the travel time and the emergency vehicle. The dispatch information is notified to the passenger.

  However, in the prior art described in these patent documents, when a repair vehicle equipped with a repairable function does not exist in the vicinity of the construction machine to be repaired, or when a traffic jam occurs on the way, A repair vehicle in the distance will go to the site of the construction machine to be repaired. For this reason, it often takes time to start repair after a failure occurs.

Therefore, it is conceivable to obtain assistance from a leading vehicle such as a police car in order to advance the work start time for maintenance of the work equipment for such public safety management. And development of the technique which can perform a maintenance work quickly with the assistance of such a leading vehicle is desired.

Or can be received. The communication unit 6 is configured to be able to communicate with a host computer (not shown) of the vehicle location management center 50 via the communication circuit network 51.

  The vehicle position management center 50 is configured as a management server for a plurality of work vehicles 52, and is configured to be able to communicate with mobile terminals provided in the plurality of work vehicles 52. Specifically, the vehicle position management center 50 receives data indicating the current position (current position data) from a mobile terminal (not shown) provided in the work vehicle 52, and is on standby, moving, and working. It is configured to be able to receive work state data indicating which state of the work place, and to be able to transmit work place data for instructing the work place that is the destination to the mobile terminal of the work vehicle 52. ing.

  The current position data and work state data received at the vehicle position management center 50 can be further transmitted from the vehicle position management center 50 to the communication unit 6. The work location data output from the communication unit 6 is supplied to the vehicle position management center 50 through the communication network 51 and can be transmitted to each work vehicle 52 from the vehicle position management center 50.

  The control unit 2 can control each circuit device in accordance with a program stored in the ROM, execute various processing programs such as arithmetic processing, control processing, and communication processing, and read out the data to the RAM. It is for memorizing. In addition, the control unit 2 is configured to be able to read various data stored in the auxiliary storage unit 2a and to retrieve predetermined data from these various data.

  In the auxiliary storage unit 2a, storage areas of a dispatch request information storage area, a work vehicle information storage area, a required time storage area, and a standard required time storage area are stored. In these storage areas, for example, databases such as dispatch request information data table, work vehicle information data table, required time data table, standard required time data table are stored. When a program is stored in the auxiliary storage unit 2a, the stored program is once read into the RAM, and the control unit 2 executes various processes according to the program.

  In addition, the control unit 2 performs control as a so-called work moving body search unit that searches a database related to the work vehicle 52, or cooperates with the timer 5 to determine time before and after the time. It is configured to function as time calculation means for calculating and calculating time, or to generate various signals and transmit these signals through the communication unit 6. Thereby, the control part 2 is comprised so that control by the input-output of a signal may be performed between all the parts in the internal structure of the work assistance apparatus 1. FIG.

  A dispatch request information data table is stored in the dispatch request information storage area of the auxiliary storage unit 2a, which can be searched by the control unit 2 configured as described above. An example of the dispatch request information data table is shown in FIG.

As shown in FIG. 2, in the dispatch request information storage area, for example, the failure number data added by the control unit 2 and the dispatch request information data in the order of receiving the dispatch request made when the failure occurs. Received time data (operation request reception time data), data of the work vehicle requester 30 that transmitted the request for operation of the work vehicle 52 (operation requester data), data of the place where the failure occurred (work location data), work The location name data, the desired work start time data (work start desired time data) transmitted from the work vehicle requester 30 and the failure type data are associated with each other and stored as a dispatch request information data table.

  Specifically, in the dispatch request information data table according to this embodiment, for example, data related to the dispatch request associated with the failure number data of 001, 002, 003. Is stored.

  More specifically, for example, in the case of the fault with the fault number “002”, the work in which the fault has occurred is “vehicle traffic signal”, and its installation location is (300, 650), The name is “DEF intersection”, and the work vehicle dispatch request source 30 (the dispatch requester) is “Hanako Ito”. In addition, the time when the dispatch request information data transmitted from the work vehicle request source 30 due to the failure of the vehicle traffic signal is received by the communication unit 6 of the work support apparatus 1 is “14:00”. Further, the time at which the work vehicle requester 30 desires to start the trouble maintenance work or the like is “15:00” one hour after the dispatch request reception time, and the type of the trouble is “the inclination of the vehicle traffic signal”. .

  This dispatch request information data table is a data table in which the data itself increases or decreases in accordance with reception of a dispatch request accompanying the occurrence of a failure, repair of a failure by the work vehicle 52, etc. Accordingly, the status information is constantly updated. Note that these item data are not necessarily limited to the items shown in FIG. 2, and other item data can be included, or item data such as work place name data can be omitted. .

  In the work vehicle information storage area searchable by the control unit 2, the work vehicle number data, the current position data for each work vehicle 52, whether the work vehicle 52 is performing a repair work, is on standby, or moves The work state data indicating the work state in the middle, the type of work performed by the work vehicle 52, and the scheduled work end time data are associated with each other and stored as a work vehicle information data table. An example of this work vehicle information data table is shown in FIG.

  As shown in FIG. 3, in this embodiment, specifically, work vehicles 001, 002,..., 005,. Current work status data regarding a plurality of work vehicles 52 to which numbers are assigned is stored.

  In this work vehicle information data table, the current status of each work vehicle 52 is stored as information data that can be recognized by the control unit 2. More specifically, for example, in the case of the work vehicle 52 having the work vehicle number “001”, the current position of the work vehicle 52 is (200, 200), the work state is “working”, and the type of work ( Stored is an information data table in which “type of failure” is “lamp off of vehicle traffic signal” and scheduled work end time is “15:00”.

  Further, the coordinates of the current position in the work vehicle information data table become the installation position of the workpiece to be worked when the work vehicle 52 is working (working state: “working”). On the other hand, when the work vehicle 52 moves, the current position of the work vehicle 52 changes one by one. In addition, the work vehicle 52 in the standby state is a vehicle that is ready to be dispatched in response to a request for dispatch.

  The work vehicle information is information that changes every moment based on data transmitted to and received from the mobile terminal provided in the work vehicle 52. Specifically, for example, regarding a work vehicle whose work state is “working” or “standby”, the mobile terminal of the work vehicle 52 is connected to the work vehicle 52 via the vehicle position management center 50 from the communication unit 6 of the work support device 1. Communication is executed every 8 minutes. Then, the current position data and work state data of each work vehicle 52 received in this communication are stored by the control unit 2 in respective predetermined areas of the work vehicle information data table. Thereby, the work state data and the current position data in the work vehicle information data table are updated.

  On the other hand, with respect to the work vehicle 52 whose work state data is “moving”, at least communication between the vehicle position management center 50 and the mobile terminal of the work vehicle 52, and communication with the communication unit 6 of the work support device 1 as necessary. The work state data is performed every short time, specifically, for example, every minute as compared with the work vehicle 52 whose work state data is “standby” or “working”. This is because a change in the current position of the work vehicle 52 in which the work state is “moving” is significant as compared to a work vehicle in “standby” or “working”.

  In this manner, the work vehicle information data table is updated at predetermined time intervals when the state information of the work vehicle 52 is determined according to the work vehicle 52 that is moving and the work vehicle 52 that is waiting or working.

  Further, a required time data table and a standard required time data table are stored in the required time storage area and the standard required time storage area in the auxiliary storage unit 2a, respectively. An example of this required time data table is shown in FIG. 4, and an example of the standard required time data table is shown in FIG.

  That is, as shown in FIG. 4 and FIG. 5, the required time data table according to this embodiment shows the time required to move from a plurality of starting positions to a plurality of destination positions in a matrix form of starting positions and destination positions. Has been placed. The required time data table shown in FIG. 4 is the required time at the time when the dispatch request is received, and the standard time data table shown in FIG. 5 is the reference time.

  Specifically, as shown in FIG. 5, in a normal case, when the departure position is set to coordinates (X1, Y2) and the target position is set to coordinates (X1, Y7), the movement of the work vehicle 52 is “70”. It takes "minute" time. The standard required time data table shown in FIG. 5 stores the time required for the work vehicle 52 to move from the coordinates of the departure position to the coordinates of the destination position when there is no traffic jam or the like. For this reason, this standard required time data table does not change unless the situation of the road itself changes, such as when a new road is constructed or when the speed limit of the road changes. Therefore, the standard required time data table shown in FIG. 5 is stored in the standard required time storage area of the auxiliary storage unit 2a, and is read out as necessary.

  On the other hand, when a situation such as a traffic jam occurs and a change such as a longer travel time occurs due to the traffic jam, traffic information data including a changed portion, that is, traffic including difference data is sequentially transmitted from the traffic information center 20. Information data is transmitted. When the traffic information data is received by the communication unit 6, the corresponding area of the difference data in the standard required time data table shown in FIG. 5 is replaced with the difference data by the control unit 2. As a result, as shown in FIG. 4, only the data of the portion where the required time changes is updated. In FIG. 4, the corresponding portion of the difference data is shown in bold letters.

That is, the traffic information data transmitted from the traffic information center 20 is input to the control unit 2 only through the communication circuit 21 via the communication unit 6, and the required time data table is updated. The respective data tables stored in the dispatch request information storage area, the work vehicle information storage area, and the required time storage area can be searched by the control unit 2 in the state stored in the auxiliary storage unit 2a. ing.

  The work support device 1, the leading vehicle management center 10, the traffic information center 20, the work vehicle request source 30, the emergency light management center 40, and the vehicle position management center 50 are respectively connected to the communication circuit networks 11, 21, 31. , 41, 51 through the communication unit 6, and a work support system according to this embodiment is configured.

(Work support method)
Next, a work support method using the work support apparatus 1 according to this embodiment configured as described above will be described. FIG. 6 shows a flowchart of an example of the work support method according to this embodiment, and FIG. 7 shows an example of the current position of each work vehicle and the place where each failure occurs.

  That is, as shown in FIG. 6, first, when a failure occurs in the workpiece, the work vehicle requester 30 provides information for repairing the workpiece, that is, failure information data, work location data, and work start request. Dispatch request data including time data is output and transmitted. The output dispatch request data is received by the communication unit 6 functioning as receiving means via the communication network 31. In the work support apparatus 1, the control unit 2 adds failure number data to the dispatch request data including the work place data and the desired work start time data and stores the failure number data in the dispatch request information storage area of the auxiliary storage unit 2a. The dispatch request data table is updated.

  In this embodiment, as an example, for example, when the dispatch request data associated with the occurrence of a failure “lamp off” is received at “15:00” in the “vehicle traffic signal” at the “GHI intersection”, As shown in FIG. 2, “003” is assigned as a failure number to the dispatch request data, and is sequentially added to the dispatch request information data table in the dispatch request information storage area.

  In this way, in step ST1, the installation location data and the work start desired time data of the workpiece in which the failure has occurred are received. Next, the process proceeds to step ST <b> 2, and work vehicle information data including current position data and work state data of each work vehicle 52 collected and accumulated in the vehicle position management center 50 is transmitted from the vehicle position management center 50. And received by the communication unit 6 via the communication network 51.

  In the work support device 1 that has received the work vehicle information data, the control unit 2 extracts current position data and work state data included in the work vehicle information data. These current position data and work state data are stored in the work vehicle information storage area of the auxiliary storage unit 2a, and the work vehicle information data table shown in FIG. 3 is updated.

  The item data updated in the work vehicle information data table at this stage is at least current position data and work state data as shown in FIG. If necessary, the work vehicle information data may be updated as data including work type data and work end scheduled time data. Further, the item data is not necessarily limited to the item data shown in FIG. 3, and other item data can be included, or work type data can be omitted.

Next, the process moves to step ST3 shown in FIG. 6, and the work location data and work in the dispatch request information data table stored in the dispatch request information storage area of the auxiliary storage unit 2a by the control unit 2 of the work support apparatus 1 Current position data and work state data stored in the vehicle information storage area are searched.

  That is, first, the control unit 2 searches for the work vehicle 52 in which the work state data is searched and the work state data is “standby”. In this embodiment, work vehicles having work vehicle numbers “003”, “004”, and “005” are searched for as work vehicles whose work state data is “standby” (see FIG. 3).

  Next, the work vehicle closest to the work place data is searched from the work vehicle information data whose work state is “standby”. In this embodiment, as shown in FIG. 7, since the obstacle requested to be dispatched is “003”, the work vehicle with the work vehicle number “003” as the work vehicle at the closest position is in standby. 52 is searched.

  Next, the process proceeds to step ST4 shown in FIG. 6, and the traffic information data transmitted from the traffic information center 20 through the communication circuit network 41 is received by the communication unit 6. The traffic information data received by the communication unit 6 includes accident information data, traffic jam information data, difference data, and the like. Thereafter, the process proceeds to step ST5, and the control unit 2 and the timer 5 use the received traffic information data to wait until the work vehicle 52 waiting in the place nearest to the place where the failure arrives at the place where the failure occurs. Time is calculated.

  In this embodiment, the required travel time from the current position (“500, 300”) of the work vehicle with the work vehicle number “003” on standby until it arrives at the location (“600, 200”) where the failure occurred. Is calculated.

  That is, the required time data table (see FIG. 4) updated based on the difference data included in the traffic information data is retrieved by the control unit 2, and the coordinates with the current position of the selected work vehicle 52 as the starting position are searched. The time at the intersection of the coordinates where the failure location is the target position is extracted as the movement time. Then, the control unit 2 calculates the scheduled time at which the work vehicle “003” arrives at the installation location of the failed device by using the extracted required time data and the current time which is always kept by the timer 5. The estimated arrival time data is generated.

  Thereafter, the process proceeds to step ST6, where the work place data and the failure information data are transmitted to the work vehicle 52 of the extracted vehicle number “003”. The work location data and the failure information data are received by the vehicle position management center 50 via the communication network 51 and transmitted to the mobile terminal of a predetermined work vehicle 52. The work vehicle 52 that has received these data is equipped with necessary equipment and ready to move to the work place.

  Next, the process proceeds to step ST7, and the control unit 2 functioning as a time determination unit performs a process of determining whether or not the work vehicle 52 can arrive at the failure occurrence location at a time before the work start desired time. Is done. That is, the control unit 2 compares the estimated arrival time data generated in step ST5 with the desired work start time data of the dispatch request data table stored in the dispatch request information storage area of the auxiliary storage unit 2a. If the estimated arrival time is before the desired work start time, the control unit 2 determines that arrival is possible before the desired work start time, and the work support process ends.

  On the other hand, if the estimated arrival time is later than the desired work start time, the control unit 2 determines that arrival is not possible before the desired work start time, and the process proceeds to step ST8. In step ST8, the control unit 2 includes information data including information that the time when the work vehicle 52 arrives at the work place is a time that is later (not in time) than the desired work time, and the expected arrival time data of the work vehicle. Is transmitted to the work vehicle requester 30 through the communication unit 6 and the communication network 31.

  Thereafter, the process proceeds to step ST9, and whether there is traffic congestion on the road on which the work vehicle 52 travels until it arrives at the work place based on the traffic information data received in step ST4 by the control unit 2. A traffic jam determination process is executed. That is, a determination process is performed to determine whether or not the cause of the time when the work vehicle 52 arrives at the work place being a time after the desired work time is traffic jam.

  In this embodiment, the traffic information information included in the traffic information data is retrieved by the control unit 2 that functions as a cause determination unit. As a result, the control unit 2 searches for a road condition on the way to the work place (600, 200) from the position (500, 300) where the work vehicle 52 with the vehicle number “003” is waiting.

  When the control unit 2 determines that no traffic jam has occurred on the road on which the work vehicle 52 is scheduled to travel based on the traffic jam information data, the work support process ends. On the other hand, if it is determined by the control unit 2 based on the traffic jam information data that there is a traffic jam on the road on which the work vehicle 52 is scheduled to travel, the process proceeds to step ST10, where “waiting process” or “ "Emergency light processing" is executed.

(Meeting process)

  Thereafter, as shown in FIG. 8, in step S1, the control unit 2 shown in FIG. 1 uses the communication unit 6 to the leading vehicle management center 10 for data on the meeting place of the leading vehicle and the work vehicle 52 and permission to use the leading vehicle. Application data is sent. Note that a plurality of predetermined places may be determined in advance as the meeting place, and a position closest to the current position of the work vehicle 52 may be selected from the plurality of places.

  Then, the process proceeds to step S <b> 2, and in the leading vehicle management center 10, examination processing for the meeting place and the application is executed according to the meeting place data and the application data transmitted from the communication unit 6 of the work support device 1. After the examination process is completed, approval data is transmitted from the leading vehicle management center 10 via the communication circuit network 11. And the leading vehicle management center 10 transmits the data of the meeting place to the leading vehicle.

  Thereafter, the process proceeds to step S3, and in the work support apparatus 1 from which the approval data is received by the communication unit 6, the control unit 2 transmits meeting place data as the place data through the communication unit 6. The vehicle location management center 50 that has received the location data transmits the meeting location data to the corresponding work vehicle 52. Thereby, the work vehicle 52 becomes a state which can move to the received place data.

  Thus, the waiting process is executed. The work vehicle 52 that has moved to the meeting place can join the leading vehicle at this meeting place. Thereafter, the work vehicle 52 is led by the lead vehicle and can move to the work place that is the original destination place as the priority vehicle.

(Emergency light processing)
Next, emergency light processing will be described. That is, in the emergency light process according to this embodiment, when the road to which the work vehicle 52 is congested in step ST9 shown in FIG. 6, first, as shown in FIG. Information data (use permission request data) for requesting use permission of the emergency light is transmitted from the communication network 11 to the emergency light management center 40.

  Thereafter, the process proceeds to step S12, and the emergency light management center 40 executes a screening process according to the use permission request data transmitted from the work support apparatus 1. After completion of the examination process, use permission information data is transmitted from the emergency light management center 40 via the communication circuit network 41 in step S13.

  Thereafter, in step S 14, after the use permission information data is received by the communication unit 6, the control unit 2 issues an emergency to the corresponding work vehicle 52 via the communication unit 6, the communication network 51, and the vehicle position management center 50. Information data indicating that the lamp use permission data has been received is transmitted. Thereby, it becomes possible for the work vehicle 52 to use an emergency light, and it is possible to run as a priority vehicle.

  As described above, the work support process according to this embodiment is executed. Actually, the work vehicle 52 moves to the work place to perform a predetermined work, and the movement status is managed one by one by the vehicle position management center 50. In addition, the work vehicle state data transmitted from the vehicle position management center 50 is received by the communication unit 6, whereby the control unit 2 updates the work vehicle information data table in the work vehicle information storage area.

  As described above, according to the work support device and the work support method according to this embodiment, it is possible to reach the place where the failure occurs in a short time, and the work request source 30 that requested the work vehicle to be dispatched In addition to being able to communicate the arrival status of the vehicle, if the arrival at the work place is not in time for the desired start time due to traffic jams, etc. It is possible to request use and to obtain the permission promptly, so that it is possible to arrive at the work place quickly.

  Although one embodiment of the present invention has been specifically described above, the present invention is not limited to the above-described embodiment, and various modifications based on the technical idea of the present invention are possible.

  For example, numerical data such as time and current position, work vehicle information data, work start desired time data and the like given in the above-described one embodiment are merely specific examples in the description, depending on individual specific situations, Different numerical data such as time and current position, work vehicle information data, desired work start time data, and the like are employed.

  For example, in the above-described embodiment, the standard required time data table shown in FIG. 5 is treated as fixed data stored in the standard required time storage area of the auxiliary storage unit 2a. For example, when the work support device 1 is activated, the standard required time data is received from the traffic information center 20 and stored as a standard required time data table in the standard required time storage area. good.

Further, for example, in the above-described embodiment, as shown in FIG. 6, after performing the estimated arrival time calculation process in step ST5, the work place data and the work information data are transmitted to the work vehicle in step ST6. However, the processing in step ST5 and step ST6 can be performed in reverse. Also, in the reception of traffic information data in step ST4, the traffic information data may be received every predetermined time by the communication unit 6 regardless of before and after processing.

  Further, for example, in the above-described embodiment, the scheduled arrival time data of the work vehicle 52 and the information data including the content that the arrival of the work vehicle 52 comes after the desired work start time are transmitted via the communication network 31. However, it is not necessarily transmitted to the work vehicle request source 30, and any method can be adopted as long as the work vehicle request source 30 notifies the recognizable information. is there.

  Specifically, for example, information on the estimated arrival time of the work vehicle 52 and / or information on the content not in time for the desired work start time is transmitted to a server of a predetermined bulletin board site on the Internet, and the work vehicle requester 30 By accessing the web page of the bulletin board, it is also possible to adopt a method in which the work vehicle 52 recognizes information that is not in time or information on estimated arrival time.

  Further, for example, in the above-described embodiment, the control unit 2 that performs the calculation process of the estimated arrival time is employed as the time calculation means in the work support apparatus. It can also be performed externally. That is, the time calculation means can be installed outside the work support device. Specifically, a time calculation device that executes time calculation processing is provided outside the work support device, and the time calculation means and the work support device are configured to be able to communicate with each other. Then, in the work support device, the work location data received by the communication unit 1 and the current position data of the work vehicle 52 searched by the control unit 2 are transmitted from the communication unit 1 to the time calculation device. Thereafter, the time calculation device calculates the estimated arrival time based on the work place data and the current position data. The calculated estimated arrival time is generated as estimated arrival time data and transmitted to the work support apparatus. In the work support device that has received the estimated arrival time data, the same processing as that after calculation of the estimated arrival time in the above-described embodiment is performed. The time calculation device may be installed alone as the time calculation processing center, or may be installed in the leading vehicle management center 10, the traffic information center 20, the emergency light management center 40, or the vehicle position management center 50.
