The section damage degree 64 is set according to the structure damage degree 47 of the railway structure included in the folded section. A loopback section with a low section damage degree 64 is preferentially patroled. This is because priority is given to returning sections that do not require time for recovery.
In the embodiment of the present invention, the section damage degree 64 is defined in three stages of “small”, “medium”, and “large”. A turn-around section having a section damage degree 64 value of “small” is treated as a patrol section. A folded section having a section damage degree 64 of “medium” is treated as a repair section. A turn-around section with a section damage degree 64 value of “large” is determined to be difficult to recover early, and is excluded from the scope of the embodiment of the present invention.

  FIG. 9 is a flowchart showing details of the damage degree calculation process. The flowchart shown in FIG. 9 is executed by the server 3 when an abnormality such as an earthquake occurs. It is assumed that the server 3 receives measurement data from the sensor network 2 as needed and stores the latest measurement data in the storage unit 22.

  As shown in FIG. 9, the control unit 21 of the server 3 selects one turn-back section as a processing target (S101). Next, the control unit 21 of the server 3 selects one structure in the turn-back section selected in S101 as a processing target (S102). As described above with reference to FIG. 4, the railroad structure table 41 stores information on the railroad structure linked to the turn-back section, so the control unit 21 of the server 3 stores the railroad structure table 41. By searching, it is possible to specify a structure in the turn-back section.

  Next, the control unit 21 of the server 3 acquires measurement data related to the structure selected in S102, calculates the structure damage degree, and stores the calculation result in the structure damage degree 47 of the railway structure table 41 ( S103). The degree of structural damage is described in Japanese Patent Application Laid-Open No. 2008-215962, Japanese Patent Application Laid-Open No. 2007-271362, Japanese Patent Application Laid-Open No. 2008-134117, etc. It can be calculated by applying the described technique.

  In the embodiment of the present invention, the degree of structural damage is defined in three stages, for example, “small”, “medium”, and “large”, similarly to the section damage. A structure with a small damage value of the structure is inspected by inspection. A structure with a medium damage value of “medium” is repaired. A structure having a structure damage degree value of “large” is determined to be difficult to repair in a short time, and is excluded from the scope of the embodiment of the present invention.

  Next, the control unit 21 of the server 3 confirms whether or not the structure selected in S102 is the last structure included in the turn-back section selected in S101 (S104). When it is not the last structure (No in S104), the control unit 21 of the server 3 repeats from S102. In the case of the last structure (Yes in S104), the control unit 21 of the server 3 proceeds to S105.

  Next, the control unit 21 of the server 3 calculates the section damage degree based on the structure damage degree calculated in S103, and stores the calculation result in the section damage degree 64 of the calculation result table 61 (S105).

For example, when all the structural damage degrees calculated in S103 are “small”, the control unit 21 of the server 3 sets “small” as the section damage degree, and at least one of the structural damage degrees is “large”. In this case, “Large” is set as the section damage degree, and “Medium” is set as the section damage degree in other cases.
In addition, the control unit 21 of the server 3 may set the section damage degree based on various statistical values such as the average value of the structure damage degree calculated in S103, for example.

  Next, the control unit 21 of the server 3 checks whether or not the return section selected in S101 is the last return section (S106). When it is not the last turn-back section (No in S106), the control unit 21 of the server 3 repeats from S101. In the case of the last return section (Yes in S106), the control unit 21 of the server 3 ends the process.

  FIG. 10 is a flowchart showing details of the restoration priority calculation process. The flowchart shown in FIG. 10 is executed by the server 3 when an abnormality such as an earthquake occurs. Either of the processes shown in FIGS. 9 and 10 may be executed first or in parallel.

  As illustrated in FIG. 10, the control unit 21 of the server 3 selects one turn-back section as a processing target (S201). Next, the control unit 21 of the server 3 acquires the degree of influence (information in the degree of influence table 71) regarding the loopback section selected in S201, calculates the restoration priority, and calculates the calculation result as the restoration priority in the calculation result table 61. 63 (S202).

  The restoration priority is calculated based on whether or not the transfer is possible 73, the alternative route presence / absence 74, the suspension loss 75, the suspension influence number 76, and the like in the impact table 71. For example, passengers are not immovable even if they are suspended in a return section where there is a station where transfer is possible, and a return section where there is an alternative route by another means of transportation (other company's route, bus, etc.) Therefore, the recovery priority is set low. Further, for example, a recovery priority value is set to be high for a turn-around section in which passengers cannot move during suspension of operation and the number of affected persons is large. Note that the restoration priority setting criteria are not limited to these examples, and the control unit 21 of the server 3 sets the restoration priority so that the social influence can be minimized.

  Next, the control unit 21 of the server 3 checks whether or not the return section selected in S201 is the last return section (S203). When it is not the last return section (No in S203), the control unit 21 of the server 3 repeats from S201. In the case of the last turn-back section (Yes in S203), the control unit 21 of the server 3 ends the process.

  FIG. 11 is a flowchart showing details of the repair order calculation process. The flowchart shown in FIG. 11 is executed by the server 3 after the processes in FIGS. 9 and 10 are completed.

  The control unit 21 of the server 3 searches the calculation result table 61 and acquires a repair section (S301). As described above, the repair section is a turn-around section in which the section damage degree 64 is “medium”. The control unit 21 of the server 3 searches the calculation result table 61 using the value of the section damage degree 64 as “medium” as a search condition, acquires a set of return section IDs 62 indicating repair sections as a search result, To remember.

  Next, the control unit 21 of the server 3 calculates the repair rank for the set of turnaround section IDs 62 acquired in S301, and stores the calculation result in the repair rank 65 of the calculation result table 61 (S302).

  For the repair order, for example, the repair cost 46 of the railway structure table 41 is referred to and the repair cost 46 is set in ascending order. In addition, for example, for a repair section with a very high restoration priority (for example, determination is made by setting a predetermined threshold), the repair order is replaced, or the work is advanced in parallel regardless of the repair cost 46. The order of indication (for example, “0”, etc.) is set. It should be noted that the setting criteria for the repair order is not limited to these examples, and the control unit 21 of the server 3 gives priority to the return section that can be quickly restored while minimizing the social impact. Set.

  Next, the control unit 21 of the server 3 transmits a list of calculated repair orders (for example, data in which repair sections are arranged and listed in ascending order of repair orders) to the display device 4 set in the central command center. (S303). The control unit 21 of the display device 4 at the central command center displays the received list of repair orders on the display unit 26. As a result, it is possible to carry out maintenance work for each railway structure based on the order of repair calculated in consideration of the degree of damage to the railway structure, social impact during suspension, and ease of repair. In particular, since the repair rank is calculated for each turn-back section, it is possible to achieve a quick recovery based on the turn-back operation.

  FIG. 12 is a flowchart showing details of the inspection route calculation process. The flowchart shown in FIG. 12 is executed by the server 3 after the processes in FIGS. 9 and 10 are completed. Further, either of the processes shown in FIGS. 11 and 12 may be executed first or in parallel.

  The control unit 21 of the server 3 searches the calculation result table 61 and acquires the inspection section (S401). As described above, the inspection section is a turning section in which the value of the section damage degree 64 is “small”. The control unit 21 of the server 3 searches the calculation result table 61 using the fact that the value of the section damage degree 64 is “small” as a search condition, acquires a set of loopback section IDs 62 indicating the inspection section as a search result, To remember.

  Next, the control unit 21 of the server 3 calculates a patrol route for the set of loopback section IDs 62 acquired in S401, and stores the calculation result in the patrol route rank 66 of the calculation result table 61 (S402).

First, the control unit 21 of the server 3 determines which inspection section is to be assigned to which ward based on the latitude / longitude 83 of the ward table 81, the number of inspectors 84, and the like. For example, assuming that the inspection section exists within a predetermined radius, the inspection section is distributed and assigned according to the number of inspectors 84. Further, for example, the inspection section is not assigned to the district where the number of inspectors 84 is insufficient for the number of persons required for the inspection.
Next, the control unit 21 of the server 3 patrols each ward based on the latitude / longitude 83 of the ward table 81, the importance 45 of the railway structure table 41, and the restoration priority 63 of the calculation result table 61. Determine the inspection order of the sections. For example, with reference to the importance 45, the inspection order is determined so that the inspection section in which there is a railway structure that has been damaged in the past is preferentially inspected. Further, for example, the restoration priority 63 is referred to and the inspection order is determined so that inspection is performed in the order of the restoration priority.
When continuously inspecting non-adjacent inspection sections, the control unit 21 of the server 3 calculates an inspection route including a road connecting the inspection sections. Here, the control unit 21 of the server 3 calculates the inspection route in consideration of road information (information such as traffic jams and traffic closures).
In addition, the calculation reference | standard of a patrol route is not limited to these examples, The control part 21 of the server 3 considers the past experience, the present road information, etc., keeping a social influence to the minimum. To calculate a patrol route.

  Next, the control unit 21 of the server 3 transmits the calculated inspection route to the display device 4 set in the corresponding ward (S403). The control unit 21 of the ward office display device 4 displays the received list of repair orders on the display unit 26. Thereby, the inspection work of each railway structure can be performed based on the patrol route calculated in consideration of the social influence at the time of suspension, past experience, current road information, and the like. In particular, since the inspection route rank is calculated for each turn-back section, it is possible to achieve a quick recovery based on the turn-back operation.

FIG. 13 is a diagram illustrating a display example of the inspection route.
In the example illustrated in FIG. 13, the W line A station to the D station are turned-back sections. Similarly, the X-line A station to the E station, the Y line G station to the H station, and the Z line F station to the A station are turned-back sections.
The route 1 is a route on the line that departs from the ward office and performs inspection from the A station to the D station on the W line. The route 2 is a route on the road moving from the D station on the W line to the G station on the Y line. The route 3 is a route on the line for performing an inspection from the G station to the H station on the Y line. The route 4 is a route on the road moving from the H station on the Y line to the F station on the Z line. The route 5 is a route on a track for performing an inspection from the F station of the Z line to the A station. The route 6 is a route on a track for performing an inspection from the X-ray A station to the E station.

  FIG. 14 is a flowchart showing details of the damage degree update process. The flowchart shown in FIG. 14 is executed by the server 3 when the inspector transmits the inspection result to the server 3 after the processing of FIG.

  As illustrated in FIG. 14, the control unit 21 of the server 3 receives the inspection result from a portable terminal or the like included in the inspector (S501). The inspection result may be, for example, a value of a structure damage degree, or may be various data that cannot be measured by a sensor.

  Next, the control unit 21 of the server 3 calculates the section damage degree, the repair order, and the inspection route based on the inspection result, and stores the calculation results in the section damage degree 64 and the repair order 65 of the calculation result table 61 ( S502). The section damage degree, the repair order, and the inspection route are the same as S105 in FIG. 9, S302 in FIG. 11, and S402 in FIG.

  Next, the control unit 21 of the server 3 transmits the calculated list of repair orders to the display device 4 installed at the central command station (S503). The control unit 21 of the display device 4 at the central command center displays the received list of repair orders on the display unit 26. As a result, it is possible to carry out maintenance work for each railway structure at the central command center based on an accurate repair order based on the inspection result of the inspector.

  Next, the control unit 21 of the server 3 transmits the calculated inspection route to the display device 4 installed in the corresponding ward (S504). The control unit 21 of the ward office display device 4 displays the received list of repair orders on the display unit 26. Thereby, based on the exact repair order based on the inspection result of the inspector, the inspection work of each railway structure in the ward can be performed.

  As described above, in the embodiment of the present invention, it is necessary to calculate a repair rank for a repair section (a folded section that requires repair) and to perform a visual inspection by a patrol section (inspector patrols). Since the inspection route is calculated for the loopback section), maintenance work and inspection work can be integrally supported.

  In addition, since the repair rank and the inspection route are calculated for each turn-around section (section of the railway line divided for each station having the turn-back facility), it is possible to achieve a quick recovery based on the turn-around operation.

  In addition, since it is equipped with an impact table that stores information on social impact and a railway structure table that stores repair costs, etc., repairs calculated taking into account the social impact during suspension, ease of repair, etc. Based on the ranking, maintenance work for each railway structure can be performed.

  In addition, since it has an impact level table that stores information on social impact levels and a railway structure table that stores the importance level indicating past damage history, etc., the social impact at the time of suspension, past experience, etc. are taken into account. Based on the patrol route calculated in this way, the inspection work of each railway structure can be performed.

  The preferred embodiments of the maintenance inspection work support system and the like according to the present invention have been described above with reference to the accompanying drawings, but the present invention is not limited to such examples. It will be apparent to those skilled in the art that various changes or modifications can be conceived within the scope of the technical idea disclosed in the present application, and these naturally belong to the technical scope of the present invention.
