The information processing system S includes an information processing device 1 and an information terminal 2. The information processing device 1 is communicably connected to the information terminal 2 via a network.

The information processing device 1 acquires information about the base station where the failure has occurred, generates a travel route for restoring the base station based on the acquired information, and transmits the generated route to the information terminal 2. Output. The information processing device 1 is, for example, a server. Information is displayed in response to a request from the information terminal 2.

The information terminal 2 is a terminal used by a user, and is, for example, a personal computer, a tablet, or a smartphone. The user of the information processing system S is, for example, a person in charge of controlling the restoration work of the base station.

Processing in the information processing device 1 will be explained. The information processing device 1 acquires failed base station information D. The failed base station information D is information indicating a base station where a failure has occurred.

The information processing device 1 outputs the generated route. In addition to the generated route, the information processing device 1 may further output travel time and work time.

The information processing device 1 has the effect of providing information to support efficient recovery work.

[Configuration of information processing device 1]
FIG. 2 is a block diagram showing the configuration of the information processing device 1. As shown in FIG. The information processing device 1 includes a communication section 11, a storage section 12, and a control section 13. The control unit 13 includes an acquisition unit 131 , a specification unit 132 , a route generation unit 133 , an output unit 134 , a calculation unit 135 , and a reception unit 136 .

The communication unit 11 is a communication interface for transmitting and receiving data to and from other devices via a network. The storage unit 12 is a storage medium including a ROM (Read Only Memory), a RAM (Random Access Memory), an SSD (Solid State Drive), a hard disk drive, and the like. The storage unit 12 stores in advance a program to be executed by the control unit 13.

The storage unit 12 stores importance information that associates base stations with the importance of the base stations. FIG. 3 is a diagram showing an example of the data structure of importance information stored in the storage unit 12. In the importance information shown in FIG. 3, "base station ID", "position", and "importance" are associated. “Base station ID” is an ID (Identification) for identifying the base station. "Position" indicates the location of the base station. "Importance" indicates the importance of the base station. With regard to "importance", high importance is set for base stations that cover the locations of government offices and important customers.

The storage unit 12 stores work group information that associates work groups with bases of each work group. FIG. 4 is a diagram showing an example of the data structure of work team information stored in the storage unit 12. In the work group information shown in FIG. 4, "work group ID" and "base location" are associated. “Work group ID” is an ID for identifying a work group. “Base location” indicates the address of the base of the work group. The "base location" may be indicated by the coordinates of the location of the base.

The control unit 13 is, for example, a processor such as a CPU (Central Processing Unit). The control unit 13 functions as an acquisition unit 131 , a specification unit 132 , a route generation unit 133 , an output unit 134 , a calculation unit 135 , and a reception unit 136 by executing programs stored in the storage unit 12 .

The acquisition unit 131 acquires failed base station information indicating a base station where a failure has occurred. As an example, the faulty base station information includes a base station ID (Identification) of a base station where a fault has occurred. The acquisition unit 131 may acquire failed base station information from, for example, an external device. Further, the reception unit 136 receives a selection of a base station in which a failure has occurred from the user, generates failure base station information based on the accepted selection, and the acquisition unit 131 receives the failure base station information generated by the reception unit 136. Information may also be obtained.

The identifying unit 132 identifies one or more base stations to be worked on among the base stations in which a failure has occurred, which is indicated by the failed base station information acquired by the acquiring unit 131 . For example, the identifying unit 132 identifies the base station to be worked on based on the content of the failure occurring in the base station. Specifically, based on the content of the fault included in the faulty base station information, a base station with a fault that can be quickly recovered may be identified as the base station to be worked on. The content of the failure may be, for example, an alarm occurring at the base station, or may be information indicating a problem occurring at the base station, such as "commercial power outage" or "line disconnection". . The identifying unit 132 may identify the base station to be worked on based on the importance of the base station, as described later. Further, the identifying unit 132 may identify a base station selected by the user from among the base stations where a failure has occurred as the base station to be worked on.

The route generation unit 133 generates a route for a work team performing restoration work to each of the one or more work target base stations identified by the identification unit 132. As an example, the route generation unit 133 uses a known route search algorithm to generate a route that allows the user to travel to the target base station identified by the identification unit 132 in the shortest travel time. The route generation unit 133 may add the time required for recovery of each base station calculated by the calculation unit 135 and then generate a route such that the total of travel time and work time is minimized.

When there are multiple work teams, the route generation unit 133 creates a collision-free route for each work team and travels to the work target base station identified by the identification unit 132 in the shortest travel time. Generate a route that can be used.

The output unit 134 outputs the route generated by the route generation unit 133. As an example, the output unit 134 causes the information terminal 2 to display a screen shown in FIG. 5 based on a request to display a route received from the information terminal 2. FIG. 5 is a diagram showing an example of a screen output by the output unit 134. In the screen shown in FIG. 5, base stations to be worked on (black circles) and routes (R1 and R2) to travel between the base stations to be worked on, generated by the route generation unit 133, are displayed on the map. . In the example shown in FIG. 5, the base stations to be worked on are assigned to each of the two work teams so that they do not overlap, and the route for moving the base stations to be worked on that is assigned to each work team is displayed. ing. The output unit 134 may display an interface for selecting a work group whose detailed travel route is to be displayed from among a plurality of work groups. When a work group is selected, the output unit 134 displays details of the route generated for the selected work group.

By configuring the information processing device 1 in this way, it is effective in providing information to support efficient recovery work.

The information processing device 1 may be configured to generate a travel route in consideration of different bases for each work group. The route generation unit 133 generates a route for the work team to take starting from the base of the work team stored in the storage unit 12 . In the screen shown in FIG. 5, triangles indicate bases of work teams. Furthermore, the route generation unit 133 may generate a route with the base of the work group as the end point.

The information processing device 1 may be configured to calculate the work time required for the recovery work. In this case, the obtaining unit 131 obtains faulty base station information indicating the faulty base station and the details of the fault occurring in the base station.

The calculation unit 135 calculates the one or more work target base stations identified by the identifying unit 132 based on the content of the failure of the base station corresponding to the one or more work target base stations identified by the identifying unit 132 in the failed base station information. Calculate the work time required for each recovery task. As an example, the storage unit 12 stores work information that associates the details of the failure with the work time required for recovery work. In the work information, for example, if the content of the failure occurring at the base station is "commercial power outage", the work time is "30 minutes", and if the content of the failure is "line disconnection", the work time is 30 minutes. is associated with "2 hours".

The calculation unit 135 refers to the work information stored in the storage unit 12 and identifies the work time corresponding to the content of the failure indicated by the failed base station information. The calculation unit 135 may calculate the total work time required to restore each base station on the route generated by the route generation unit 133. On the screen shown in FIG. 5, an estimate of the work time required for restoration work at each base station and the total work time at the base stations on the route of the work team are displayed.

By configuring the information processing device 1 in this way, it is possible to roughly estimate the time required to restore the base station when dispatching a restoration worker.

The information processing device 1 may be configured to further calculate the travel time. The calculation unit 135 further calculates the travel time required for the work team to travel along the route. Specifically, the calculation unit 135 calculates the travel time required to travel between base stations on the route generated by the route generation unit 133, based on the map data.

The output unit 134 further outputs the work time and travel time calculated by the calculation unit 135. The screen shown in FIG. 5 further displays the total travel time required for moving between base stations on the route generated by the route generation unit 133, calculated by the calculation unit 135, and the work time required for recovery of each base station. has been done. The displayed travel time may further include the travel time from the base of each work team to the first base station. Further, on the screen shown in FIG. 5, the total of the travel time and work time of the work group to be displayed is displayed.

By configuring the information processing device 1 in this way, when dispatching a recovery worker, it is possible to grasp the approximate time required for base station recovery and travel time, and the person in charge of controlling the recovery work can determine the recovery time. You will be able to easily plan your work.

By allowing those in charge to understand how the movement routes differ depending on how many work teams are involved, it becomes easier to plan recovery operations.

The route generation unit 133 uses the number of work teams performing restoration work as a parameter to provide a route for each work team to go to the base station to be worked on so that the base stations to be worked on that are assigned to the work teams do not overlap. It is generated for each value of the number of work teams assigned. The route generation unit 133 changes the value of the number of work teams and generates a route pattern for the work teams of each value to perform restoration work so that the base stations to be worked on do not overlap. The route generation unit 133 generates a route pattern for each set number of work teams. That is, when routes are generated for three patterns in which the number of work teams is 1, 2, and 3, the route generation unit 133 generates three route patterns.

FIG. 6 is a diagram showing an example of a screen displayed by the output unit 134. On the screen shown in FIG. 6, an interface L is arranged for selecting a route pattern to be displayed from among the generated route patterns. When the user selects interface L, a list of the number of work groups is displayed, and the user selects the number of groups from the displayed list. Note that the list of the number of work teams includes the value of the number of teams used as a variable when the route generation unit 133 generates the route pattern. That is, when the route generation unit 133 generates routes for three patterns of the number of work teams, 1, 2, and 3, the list of the number of work teams has values of 1, 2, and 3. The output unit 134 displays a route pattern corresponding to the selected number of groups. On the screen shown in FIG. 6(a), the route corresponding to the number of groups "2" among the route patterns generated by the route generation unit 133 is displayed, and on the screen shown in FIG. 6(b), the route corresponding to the number of groups "2" is displayed. The route corresponding to "1" is displayed.

By configuring the information processing device 1 in this way, the person in charge can grasp the relationship between the number of work teams to be deployed and the movement route, making it easier to plan the recovery work.

There are cases where it is desired to know how many work teams should be deployed to complete the restoration work within a reasonable time. Therefore, the information processing device 1 may be configured to determine the required number of work teams based on the calculated work time and travel time.

Specifically, the output unit 134 determines the number of work teams based on the total work time and travel time calculated by the calculation unit 135. As an example, the storage unit 12 stores an upper limit of the time during which work or movement is possible. The upper limit of the time during which work or movement is possible is set based on, for example, the recovery time and quality assurance specified in the service terms, the time during which the worker can work continuously, and the like. The output unit 134 selects a group of work groups so that the total travel time and work time of each work group does not exceed the upper limit among the plurality of route patterns generated by the route generation unit 133 using the number of work groups as a parameter. Determine the number. As an example, the smallest number of work teams whose total travel time and work time does not exceed the upper limit is determined as the number of work teams.

The output unit 134 outputs the route, work time, and travel time of each work group corresponding to the determined number of work groups. That is, the output unit 134 displays the route, work time, and travel time of the work team for the determined number of work teams on the screen displayed on the information terminal 2.

By configuring the information processing device 1 in this way, the person in charge can grasp the amount of work teams to be assigned and the time required for recovery in that case.

For example, if the number of work teams is insufficient to respond to all base stations in which a failure has occurred, it is necessary to narrow down the base stations that will perform restoration work immediately. Therefore, the information processing device 1 may be configured to specify a base station for which restoration work is to be performed based on the importance of the base station or the details of the failure.

The identifying unit 132 determines the details of the failure occurring in each base station, which is indicated by the failed base station information, and the importance level of each base station in which the failure has occurred, which is associated with the importance information stored in the storage unit 12. , one or more base stations to be worked on are identified based on at least one of the following. As an example, the identifying unit 132 identifies, among the base stations indicated by the failed base station information, a base station in which a failure has occurred such that the work time required for recovery work is less than a predetermined threshold in the work information stored in the storage unit 12. Identify the base station to be worked on. The predetermined threshold is, for example, 60 minutes. The predetermined threshold value may be determined based on the ratio between the number of workers and the number of base stations in which a failure has occurred.

Further, the identifying unit 132 refers to the importance information stored in the storage unit 12 and identifies base stations whose importance level is equal to or higher than a predetermined importance level as base stations to be restored. The predetermined importance level is, for example, that the importance level of the base station is "B". The predetermined importance level may be determined based on the ratio between the number of workers and the number of base stations in which a failure has occurred.

By configuring the information processing device 1 in this way, it is possible to narrow down the base stations that will perform restoration work immediately, and the person in charge of controlling the restoration work can easily plan the restoration work. .

The information processing device 1 may be configured to accept input of the area to be worked on. The reception unit 136 receives input of the area to be worked on. As an example, the output unit 134 displays a screen for inputting the area to be worked on. As an example, the output unit 134 displays a screen for inputting the work target area in units of prefectures, municipalities, etc., and the reception unit 136 displays the work target area input by the user on the screen displayed by the output unit 134. get. Note that the output unit 134 displays a screen including a map for selecting a work target area, and acquires information indicating the area selected by the user.

The identifying unit 132 identifies, among the base stations included in the failed base station information, the base station corresponding to the area whose input was accepted by the accepting unit 136 as the base station to be worked on. As an example, the specifying unit 132 selects a base station located at a position corresponding to the area accepted by the receiving unit 136 as the work target base station based on the location of the base station associated with the importance information stored in the storage unit 12. Specify as a station.

By configuring the information processing device 1 in this way, a person in charge can generate and confirm a route for each area for which a recovery plan is to be established.
