Description

  The present invention relates to a traveling work support system capable of grasping the state of a traveling worker.

  In recent years, the use of tablet terminals having a GPS (Global Positioning System) function and a camera function is expanding in operations such as inspection of distribution facilities. As an advantage of using a tablet terminal having a GPS function and a camera function, for example, the current position acquired by the GPS function is displayed on a map so that a traveling operator who performs an inspection can make a destination (for example, an inspection target facility). The operator (administrator) on the office side can make a patrol work by immediately uploading the current position and inspection results of the patrol worker to the office equipment using the communication function. It is possible to grasp the current position and work status of the worker.

  Patent Document 1 discloses a system in which an administrator on the office side grasps the state of an outdoor patrol worker using the GPS function of the worker side terminal. In this system, the office-side server holds the inspection results of the patrol workers, and the worker-side terminal has the current location of the worker-side terminal and the installation location of the next inspection target equipment acquired from the office-side server. The work route is displayed based on the above, and the inspection result input from the traveling worker is uploaded to the office side server.

Here, the WEB server 5 outputs the position / inspection result information received from the worker terminal 4 to the terminal information processing apparatus 6. Further, the WEB server 5 outputs the transmission request information received from the operator terminal 3 or the worker terminal 4 to the map information distribution device 8, and the map / worker information acquired from the map information distribution device 8 is output to the operator terminal 3 or the work. To the user terminal 4. When performing a large-scale WEB service, the WEB server 5 may include a load balancer for performing load distribution.

  The terminal information processing device 6 acquires position / inspection result information from the worker terminal 4 via the WEB server 5 or the like, and stores the information in the DB server 9 (equipment information DB 11 and worker information DB 12 described later).

  The DB server 9 includes a background map DB 10, an equipment information DB 11, an operator information DB 12, and a non-communication area DB 13.

  The background map DB 10 stores map information such as a background map.

  The facility information DB 11 stores information on the facility to be inspected (installation point, facility type, and installation date), the above-described inspection results, and the like. As the terminal information processing apparatus 6 stores the position / inspection result information in the equipment information DB 11 as described above, the inspection result in the equipment information DB 11 is updated.

  In the worker information DB 12, for each worker ID, the worker's final position (the last or latest position among the current positions included in the position / inspection result information transmitted from the worker terminal 4), the worker The history of the position of the worker, the work status of the worker, whether communication between the worker terminal 4 and the map information system server 1 is possible, and communication between the worker terminal 4 and the map information system server 1 The last communication time that is the last time of communication and the predetermined action schedule information are stored.

  As the terminal information processing apparatus 6 stores the position / inspection result information in the worker information DB 12 as described above, the final position of the worker information DB 12 is updated. Further, as described later, the communication impossible area entry determination device 7 determines whether or not the worker terminal 4 has entered a predetermined communication disabled area (area) where the worker terminal 4 cannot communicate with the map information system server 1. Do. When the communication-impossible area entry determination device 7 stores the determination result in the worker information DB 12, whether or not communication is possible in the worker information DB 12 is updated.

  The action schedule information stored in the worker information DB 12 is information indicating the action schedule of the worker. The action schedule information includes, for example, the inspection target equipment (work target equipment) scheduled for inspection (work) by the operator, the installation location of the inspection target equipment indicated by latitude and longitude, and the inspection target equipment. Scheduled inspection start time (scheduled work start time), which is the scheduled time to start the inspection (work), Scheduled inspection completion time (scheduled work completion), which is the scheduled time to complete the inspection (work) for the inspection target equipment Time), circuit (route) that the worker is scheduled to move to perform inspection (work) of the inspection target equipment, and the worker (worker terminal 4) is scheduled to start staying in an area where communication is not possible For example, the scheduled start time for the stay, and the scheduled time for the completion of the stay, which is the scheduled time for the worker (worker terminal 4) to complete the stay in the area where communication is not possible.

  Heretofore, various information stored in the worker information DB 12 has been described. In the following description, various information stored in the worker information DB 12 may be collectively referred to as worker information.

  The communication disabled area DB 13 stores information on the communication disabled area (for example, polygon information indicating the shape of the communication disabled area).

  The non-communication area entry determination device 7 acquires the final position, the last communication time, and the action schedule information of each worker from the worker information DB 12, and acquires information on the non-communication area from the non-communication area DB 13. . And the communication impossible area approach determination apparatus 7 (communication impossible area approach determination part) is the work carried by the worker based on the acquired final position, final communication time, action schedule information, and information on the communication impossible area. The worker terminal 4 determines for each worker whether or not the worker terminal 4 has entered an area where communication is not possible. This determination process will be described later in detail with reference to FIG. The communication impossible area approach determination device 7 stores the determination result in the worker information DB 12.

  The map information distribution device 8 receives transmission request information from the operator terminal 3 and the worker terminal 4 via the WEB server 5. When the map information distribution device 8 receives the transmission request information, the map information distribution device 8 acquires information corresponding to setting information such as a display range and a display scale included in the transmission request information from the background map DB 10, the facility information DB 11, and the worker information DB 12. Then, the acquired information or the like is returned as a map / worker information to the request source.

  Based on the worker information stored in the worker information DB 12 and the current time, the worker state estimation unit 17 included in the map information distribution device 8 is a worker state (the current position and current position of the worker). Work situation). Specifically, when the worker terminal 4 determines that the worker terminal 4 has entered the communication disabled area by the communication disabled area entry determination device 7, the worker state estimation unit 17 uses the time when the worker terminal 4 has entered the communication disabled area. Based on a certain approach time (here, the last communication time described above), the current time, and the action schedule information, the current position and the current work status of the worker are estimated. This estimation process will be described later in detail with reference to FIGS. As the current time used for estimation, for example, the current time indicated by a timer built in the map information distribution device 8 is used. The worker state estimation unit 17 includes the estimation result in the map / worker information or stores it in the worker information DB 12.

<Operation>
Next, an outline of an operation when the map information distribution device 8 receives transmission request information from the worker terminal 4 will be described with reference to FIG.

  First, when the worker starts the system of the worker terminal 4 in step S1, the worker terminal 4 accesses the WEB server 5.

  In step S2, the WEB server 5 transmits a client system file to the worker terminal 4 in response to the access.

  In step S3, the worker terminal 4 reads the received client system file.

  In step S4, the worker terminal 4 is activated as a worker terminal of the display information system (traveling work support system) based on the read client system.

  In step S5, the worker terminal 4 receives an initial display designation (designation of a display range, a display scale, etc. for initial display of a map image) from the worker.

  In step S <b> 6, the worker terminal 4 creates transmission request information including an initial display setting corresponding to the received initial display designation and the worker ID, and sends the transmission request information to the map information via the WEB server 5. Transmit to the distribution device 8.

  In step S7, the map information distribution device 8 acquires information (for example, map information and action schedule information) according to the received transmission request information from the background map DB 10, the facility information DB 11, and the worker information DB 12. The map information distribution device 8 returns map / worker information including the acquired information to the worker terminal 4 via the WEB server 5.

  In step S8, the worker terminal 4 receives (acquires) the map / worker information. In step S9, the worker terminal 4 performs a map drawing process based on the acquired map / worker information.

  The outline of the operation when the map information distribution device 8 receives the transmission request information from the worker terminal 4 has been described above with reference to FIG. Next, an outline of an operation when the map information distribution device 8 receives transmission request information from the operator terminal 3 will be described. The operation in this case is basically the same as the operation described with reference to FIG. However, when a certain worker terminal 4 is in a communication disabled state, that is, when a certain worker has entered a communication disabled region, the worker state estimating unit 17 determines from the worker information DB 12 in step S7. Based on the acquired information, the state (current position and current work status) of the worker is estimated. Then, the map information distribution device 8 returns the map / worker information including the estimated worker state to the operator terminal 3 via the WEB server 5.

<Processing of communication impossible area approach determination device 7>
FIG. 4 is a flowchart showing the processing of the communication impossible area entry determination device 7. Next, the process of the communication impossible area approach determination apparatus 7 is demonstrated using the flowchart of FIG. In addition, the process demonstrated below is performed with respect to each worker, for example for every fixed time.

  First, in step S11, the communication-impossible area entry determination device 7 determines from the worker information DB 12 that the worker's final position, the last update time of the position information (here, the above-described final communication time), and the worker cannot communicate. The entry schedule information (here, the above-mentioned scheduled start time of stay and the scheduled time of completion of stay) indicating whether or not it is planned to enter the area is acquired. Moreover, the communication impossible area approach determination apparatus 7 acquires information on a communication disabled area from the communication disabled area DB 13.

  In step S12, the communication impossible area entry determination device 7 determines whether a predetermined time has elapsed since the last update time of the position information (here, the above-described final communication time) and enters the current time. It is determined from the schedule information (here, the stay start scheduled time and the stay completion scheduled time described above) whether or not the worker has a plan to enter an area where communication is not possible. If any of these is true, the process proceeds to step S13. Otherwise, the process proceeds to step S16.

  In step S13, the communication impossible area approach determination device 7 calculates the distance between the operator's final position and the representative point on the communication disabled area, for example, using space search. For example, a point on the non-communication area that minimizes the distance is used as the representative point on the non-communication area.

  In step S <b> 14, the non-communication area entry determination device 7 determines whether the calculated distance is within a predetermined distance. If applicable, the process proceeds to step S15, and if not, the process proceeds to step S16.

  When the process proceeds from step S14 to step S15, in step S15, the communication disabled area entry determination device 7 indicates that the worker is in a communication disabled state, that is, the worker (worker terminal 4) has entered the above communication disabled area. The determination result is stored in the worker information DB 12. Then, the process shown in FIG.

  When the process proceeds from step S12 or S14 to step S16, in step S16, the communication impossible area entry determination device 7 determines that the worker is in a communicable state, and stores the determination result in the worker information DB 12. Then, the process shown in FIG.

  As described above, the non-communication area entry determination device 7 according to the first embodiment includes the time when the position of the worker terminal 4 of the worker is updated, the entry schedule information, the position of the worker terminal 4, It is determined whether or not the worker (worker terminal 4) has entered the non-communication area based on the three factors of the distance to the representative point in the non-communication area.

  However, the present invention is not limited to this, and the incommunicable area entry determination device 7 determines whether the worker terminal 4 has entered the incommunicable area based on one or two of the three elements. Also good. However, as in the first embodiment, if it is determined whether or not the worker terminal 4 has entered the area where communication is not possible based on the three elements, the determination accuracy can be increased.

<Processing of Worker State Estimation Unit 17>
FIG. 5 is a flowchart showing the processing of the worker state estimation unit 17. Next, the processing of the worker state estimation unit 17 will be described using the flowchart of FIG. The process described below is performed for a desired worker when the map information distribution device 8 receives the transmission request information, for example.

  First, in step S <b> 21, the worker state estimation unit 17 acquires the last communication time, communication availability, and action schedule information from the worker information DB 12.

  In step S <b> 22, the worker state estimation unit 17 confirms whether or not the worker is in a communication disabled state based on the acquired communication availability. In other words, the worker state estimation unit 17 confirms whether or not the worker (worker terminal 4) has entered the area where communication is not possible. If applicable, the process proceeds to step S23, and if not, the process shown in FIG. 5 ends.

  In step S <b> 23, the worker state estimation unit 17 determines the entry time (here, the above-described final communication time) when the worker (worker terminal 4) has entered the communication disabled area, the current time, the action schedule information, Based on the above, the current position of the worker and the current work status are estimated (calculated). Then, the process shown in FIG.

  Thereafter, in a process not shown, the estimation result of step S23 is included in the map / worker information transmitted to the operator terminal 3 or the like, or stored in the worker information DB 12. When the processing shown in FIG. 5 is completed without proceeding from step S22 to step S23, information such as the current position of the worker stored in the facility information DB 11 and the worker information DB 12 by the terminal information processing apparatus 6 is provided. Is included in the map / worker information transmitted to the operator terminal 3 or the like.

  FIG. 6 is a diagram for explaining the estimation process in step S23 of the worker state estimation unit 17 according to the first embodiment. Specifically, FIG. 6 illustrates an example of information stored in the worker information DB 12 and an example of the current position estimated by the worker state estimation unit 17.

  The current position in FIG. 6 corresponds to the current position estimated by the worker state estimation unit 17, and here, a longitude of 135.000 and a latitude of 34.00 are shown.

  The current position acquisition time in FIG. 6 corresponds to an entry time (here, the above-described final communication time) at which the worker (worker terminal 4) has entered the area where communication is not possible.

  The inspection target list in FIG. 6 corresponds to the inspection target equipment included in the action schedule information.

  The scheduled inspection work time list in FIG. 6 corresponds to the scheduled inspection start time and scheduled inspection completion time included in the action schedule information. In addition, [9:30, 11:30] in the scheduled inspection work time list of FIG. 6 is the scheduled inspection start time and scheduled inspection completion time of the inspection target equipment A021 set in the inspection target list, [11: 50, 12:50] are the scheduled inspection start time and scheduled inspection completion time of the inspection target equipment A038 set in the inspection target list.

  The communication availability in FIG. 6 corresponds to the determination result of the communication disabled area entry determination device 7.

  The communication impossible area stay scheduled time list in FIG. 6 corresponds to the above-described stay start scheduled time and stay completion scheduled time included in the action schedule information.

  FIG. 7 is a diagram for explaining the estimation process in step S23 of the worker state estimation unit 17 according to the first embodiment. Specifically, FIG. 7 shows an example of information stored in the worker information DB 12.

  In FIG. 7, the installation location of the inspection target facility, the scheduled start time and the scheduled completion time of the inspection target facility, the scheduled start time and the scheduled completion time of the worker in the communication-incapable area 51, and the action schedule information The circuit 52 included in FIG. The inspection target equipment and scheduled inspection start time shown in FIG. 7 are matched with the inspection target equipment and scheduled inspection start time shown in FIG. Further, in the circuit 52 shown in FIG. 7, the direction of movement scheduled by the operator is defined, and the direction is indicated by an arrow.

  Next, the estimation process of the worker state estimation unit 17 in step S23 will be described using FIG. 6 and FIG. In addition, since step S23 is performed when the worker terminal 4 has entered an area where communication is not possible, whether communication is possible is in a communication impossible state.

  First, in the example of FIGS. 6 and 7, the scheduled start time of stay in the communication disabled area 51 is 9:00, whereas the current position acquisition time (entry time of the communication disabled area 51) in FIG. 6 is 9:20. It is. In this case, the worker state estimation unit 17 causes the worker to enter the communication disabled area 51 later than the schedule by 20 minutes, which is the difference between the stay start scheduled time and the current position acquisition time (entry time of the communication disabled area 51). Estimated to have entered.

  Then, the worker state estimation unit 17 changes the scheduled inspection start time 9:30 and the scheduled inspection completion time 11:10 corresponding to the time in the scheduled inspection work time list to 9:50 and 11:30, which are delayed by 20 minutes. Then, it is estimated that the inspection work of the inspection target equipment A021 is performed during the changed time. In addition, the worker state estimation unit 17 delays the planned stay start time 9:00 and the planned stay completion time 11:30 corresponding to the time of the scheduled stay time list in the incommunicable region by 20 minutes and 9:20 and 11:50. It is estimated that the worker stays in the communication disabled area 51 during the changed time.

  Here, for example, when the current time is 11:20, the current time is included between the changed scheduled inspection start time 9:50 and the scheduled inspection completion time 11:30. In such a case, the worker state estimation unit 17 estimates the current position of the worker as the point A marked with an X in FIG. 7, that is, the installation point (longitude / latitude) of the inspection target equipment A021. The worker's current work status is estimated to be under inspection.

  On the other hand, for example, when the current time is 11:40, the current time is after the changed scheduled inspection start time 9:50 and scheduled inspection completion time 11:30. In such a case, the worker state estimation unit 17 determines the current position of the worker as the point B marked with an X in FIG. 7, that is, the installation point of the inspection target equipment A021 (the point A in FIG. 7). From this point, it is estimated that the point on the circuit 52 has advanced in the direction of movement, and the current work status of the worker is estimated not to be inspecting (moving).

  Similarly, for example, when the current time is 9:40, the current time is before the changed scheduled inspection start time 9:50 and scheduled inspection completion time 11:30. In such a case, the worker state estimation unit 17 moves the worker's current position from the installation point of the inspection target facility A021 (point A in FIG. 7) on the circuit 52 that has traveled in the direction opposite to the movement direction. And the operator's current work status is estimated not to be inspecting (moving).

<Effect>
According to the map information system according to the first embodiment as described above, even if the worker is staying in an area where communication is not possible, the operator can use the map information system server via the operator terminal 3 or the like. By accessing 1, it is possible to easily grasp the current position and the current work status of the worker. As a result, for example, it is possible to easily determine whether or not a new inspection can be assigned (whether or not a new work can be assigned). In addition, by grasping the current position of the worker, for example, when an item to contact the worker urgently occurs, it is possible to take measures such as quickly heading to the person skilled in the art.

<Modification of Embodiment 1>
In Embodiment 1 mentioned above, the worker state estimation part 17 calculates the difference of the stay start scheduled time of the communication impossible area 51, and the last communication time (entry time of the communication impossible area 51) later than that, The estimated check start time, the scheduled check completion time, the planned stay start time, and the planned stay completion time are delayed by the calculated difference. However, the present invention is not limited to this, and the worker state estimation unit 17 calculates the difference between the planned stay start time in the communication impossible area 51 and the last communication time earlier (the entry time of the communication disabled area 51). In this case, the estimated check start time, the scheduled check completion time, the planned stay start time, and the planned stay completion time may be advanced by the calculated difference.

  In the first embodiment described above, the worker state estimation unit 17 sets the final communication time (entry time), the current time, the planned stay start time, the planned check start time, the planned check completion time, and the installation of the inspection target equipment. The worker's current position and current work situation were estimated based on the route where the point and the direction of movement were defined.

  However, the present invention is not limited to this, and the worker state estimating unit 17 excludes the installation location of the inspection target equipment and the circuit, the last communication time (entry time), the current time, the stay start scheduled time, and the inspection start schedule. Based on the time and the scheduled completion time of the inspection, the current position and the current work status of the worker may be estimated. For example, the worker state estimation unit 17 changes the scheduled check start time and the scheduled check completion time based on the difference between the last communication time (entry time) and the planned stay start time, as in the first embodiment. Then, when the current time is included between the changed scheduled inspection start time and scheduled inspection completion time, the worker state estimation unit 17 determines the current position of the worker as the installation point of the inspection target facility A021. It may be estimated that the current work status of the worker is being checked. On the other hand, when the current time is not included between the changed scheduled inspection start time and scheduled inspection completion time, the worker state estimation unit 17 determines the current location of the worker as the installation location of the inspection target facility A021. It may be estimated that the point is other than the point, and the worker's current working state is estimated to be moving.

  In the first embodiment, the worker state estimation unit 17 estimates the current position and the current work situation of the worker using the patrol circuit 52 in which the direction of movement is defined. However, the present invention is not limited to this, and the worker state estimation unit 17 uses the tour route in which the travel direction is not defined instead of the travel route 52 in which the travel direction is defined, The position and current work status may be estimated. For example, the worker state estimation unit 17 changes the scheduled check start time and the scheduled check completion time based on the difference between the last communication time (entry time) and the planned stay start time, as in the first embodiment. Then, when the current time is included between the changed scheduled inspection start time and scheduled inspection completion time, the worker state estimation unit 17 determines the current position of the worker as the installation point of the inspection target facility A021. It may be estimated that the current work status of the worker is being checked. On the other hand, when the current time is not included between the changed scheduled inspection start time and scheduled inspection completion time, the worker state estimation unit 17 determines the current location of the worker as the installation location of the inspection target facility A021. It may be estimated that the point is on the other route, and the current working status of the worker is estimated to be moving.

  Further, a point corresponding to the scheduled time for completion of the stay on the circuit 52, that is, a point where the outer line of the communication impossible area 51 and the circuit 52 intersect, such as a point C marked with an X in FIG. , May be included in the action schedule information. In this configuration, the worker state estimating unit 17 (the difference between the changed scheduled inspection time of the inspection target facility A021 and the current time) / (the scheduled inspection completion time of the changed inspection target facility A021), You may perform the multiplication which multiplies the distance value on the circuit 52 between the point A and the point C by the value of the ratio of the changed stay completion scheduled time in the communication disabled area 51. And the worker state estimation part 17 may calculate the point which advanced the patrol circuit 52 from the point A of FIG.

<Embodiment 2>
When a sudden trouble is reported at a certain facility that was not scheduled to be inspected during inspection work for power distribution facilities, it is necessary to secure workers who can immediately head to the facility (site). Sometimes. In this case, the operator determines the worker to be sent to the site, and a system that can support this determination is required. Therefore, in the second embodiment of the present invention, it is possible to support such a determination.

  FIG. 8 is a diagram for explaining the operation of the map information system according to the second embodiment. In the map information system according to the second embodiment, the same or similar components as those described above are denoted by the same reference numerals, and different points will be mainly described below.

  The map information system server 1 according to the second embodiment further includes a work allocation support device 18 shown in FIG. 8 in addition to the configuration of the first embodiment. Although not shown, the work allocation support device 18 is provided between the WEB server 5 and the DB server 9 so as to be able to input and output information, for example, similarly to the map information distribution device 8 of FIG.

  Now, in step S31 of FIG. 8, the operator terminal 3 acquires emergency work information including information on a new inspection (new work) input by the operator.

  In step S <b> 32, the operator terminal 3 transmits the acquired emergency work information to the work assignment support device 18 via the WEB server 5.

  In step S33, the work allocation support apparatus 18 derives work allocation support information as shown in FIG. 9 based on the received emergency work information and the worker information acquired from the worker information DB 12. Note that the scheduled work completion time and the scheduled communication return time in FIG. 9 correspond to the scheduled check completion time and planned stay completion time described above. The scheduled arrival time in FIG. 9 is a time derived by the work assignment support device 18, and when a new inspection that has occurred urgently is assigned to the worker, the worker installs a new inspection target facility. It is time that can arrive at. In step S <b> 33, the work assignment support device 18 transmits the derived work assignment support information to the operator terminal 3 via the WEB server 5.

  In step S34, the operator terminal 3 receives (acquires) work allocation support information. In step S35, the operator terminal 3 performs processing for displaying the acquired work allocation support information on the display device of the operator terminal 3 or the like.

  FIG. 10 is a diagram for explaining the derivation process of the work assignment support apparatus 18 according to the second embodiment. Specifically, FIG. 10 shows an example of information stored in the worker information DB 12. The installation location of the inspection target equipment, the scheduled start time of inspection and the scheduled completion time of inspection of the inspection target equipment The circuit 52 included in the action schedule information is shown. Note that the scheduled inspection start time shown in FIG. 10 is combined with the scheduled arrival time shown in FIG.

  Next, a process in which the work assignment support device 18 derives work assignment support information will be described with reference to FIGS. 9 and 10. Here, the case where the worker ID is 014 and a new inspection is assigned to the worker W1 (X mark in FIG. 10) who is not staying in the communication disabled area will be described.

  First, the work allocation support device 18 uses the information acquired from the worker information DB 12 for the worker W1 as the scheduled inspection start time and the scheduled inspection completion time for the inspection target equipment A1 at 9:30 and 11 shown in FIG. : 10 is acquired, and 11:40 shown in FIG. 10 is acquired as the scheduled inspection start time for the inspection target equipment B1. Here, as an urgent new inspection, if the inspection of the inspection target facility C1 occurs at time 11:00, the work allocation support device 18 sets the scheduled inspection completion time (11:10) of the inspection target facility A1; From the time (here 30 minutes) based on the distance on the circuit 52a between the inspection target equipment A1 and the inspection target equipment C1, the worker W1 completes the inspection of the inspection target equipment A1 and then changes to the inspection target equipment C1. The estimated arrival time (11:40) is calculated.

  Next, the work allocation support device 18 determines the inspection target facility based on the calculated scheduled arrival time (11:40) of the inspection target facility C1 and the scheduled operation time (50 minutes here) of the inspection target facility C1. The scheduled inspection completion time (12:30) of C1 is calculated. Then, the work allocation support device 18 is based on the calculated scheduled time for completion of the inspection of the inspection target facility C1 (12:30 in this case) and the distance on the circuit 52b between the inspection target facility C1 and the inspection target facility B1. From the time (here, 30 minutes), the scheduled arrival time (13:00) at which the worker W1 arrives at the inspection target equipment B1 after completing the inspection of the inspection target equipment C1 is calculated.

  Here, the scheduled arrival time at the site of arrival at the initial inspection target equipment B1, that is, the scheduled inspection start time of the inspection target equipment B1 is 11:40. The work allocation support device 18 calculates the difference (1:20) between the calculated estimated arrival time at the site (13:00) and the scheduled inspection start time (11:40) of the inspection target equipment B1 as the new inspection target equipment C1. Is calculated as the work deviation time of the worker W1.

  In the above, the work allocation support device 18 has installed the inspection target facilities A1, B1, C1, the scheduled inspection start time and the scheduled completion time of the inspection target facility A1, and the scheduled inspection start time of the inspection target facility C1. Based on the above, the process of including the worker W1 who is not staying in the communication disabled area as a candidate to be assigned a new inspection (another work) has been described.

  Here, similarly to the first embodiment, the worker state estimation unit 17 according to the second embodiment estimates the scheduled check start time and the scheduled check completion time for a worker who is staying in an area where communication is not possible. It is possible. For this reason, the work allocation support device 18 similarly applies a new inspection (separately) to an operator who stays in a communication-inhibited area based on the estimation result and the installation points of the inspection target facilities A1, B1, and C1. Can be included in the candidates to be assigned. That is, in the map information system according to the second embodiment, a new inspection (another work) is assigned to a worker who is staying in an area where communication is not possible based on the estimation result of the worker state estimation unit 17. It is configured to be included in the candidate. According to the map information system according to the second embodiment as described above, the operator can select not only workers who are not staying in the communication-disabled area but also workers who are staying in the communication-disabled area as emergency work assignment candidates. Appropriate assignment can be realized because it can be considered.

<Embodiment 3>
In Embodiment 1 and Embodiment 2, it is assumed that information regarding work cannot be obtained from a worker staying in an area where communication is not possible, but that inspection (work) is proceeding as planned. The state of the worker is estimated. If the current time does not return even after a predetermined time has elapsed from the estimated communication return time obtained by this estimation, check the work (work) of the worker who is staying in an area where communication is not possible. It is considered that a delay has occurred.

  Therefore, in the third embodiment of the present invention, when the delay occurs, it is possible to notify the operator terminal 3 which is a terminal on the office side of a warning to the outside. Hereinafter, the third embodiment will be described in detail.

  The map information system server 1 according to the third embodiment further includes a work delay notification device (not shown) in addition to the configuration of the first embodiment. The work delay notification device is provided between the WEB server 5 and the DB server 9 so as to be able to input and output information, for example, similarly to the map information distribution device 8 of FIG.

  The work delay notification device acquires, from the worker information DB 12, the scheduled communication return time of each worker who has become unable to communicate. Note that the scheduled communication return time for the worker in the communication disabled state is the time when the communication between the worker terminal 4 of the worker and the map information system server 1 is scheduled to return. This time corresponds to the estimated stay completion time. The work delay notification device determines whether or not the current time has passed a predetermined time from the scheduled communication return time (the communication disabled state is maintained even if the predetermined time has elapsed from the scheduled communication return time). Or not).

  When it is determined that the current time has passed a predetermined time from the scheduled communication return time, the work delay notification device reports that a work delay has occurred in the operator terminal 3 through the WEB server 5. Notify the warning to the outside. The operator terminal 3 displays a warning or generates a warning sound as a warning notification to the outside (for example, an operator).

  According to the display information system according to the third embodiment as described above, when a delay occurs in work in an area where communication is not possible, the operator can recognize the occurrence of the delay earlier. For example, when the operator terminal 3 (operator) has an early grasp of the occurrence of the delay, for example, an inspection (work) in which the delay is not permitted is included in the worker's action schedule, the operator terminal 3 (operator) It is possible to make a determination to assign an inspection (operation).

  It should be noted that the present invention can be freely combined with each embodiment and each modification within the scope of the invention, and each embodiment and each modification can be appropriately modified and omitted.
