As with the mileage described above, the related analysis unit 15 holds each deterioration amount for each device until the next inspection information is received, and when the next inspection information is received, the new inspection information is used. Update the amount of deterioration. Further, the related analysis unit 15 also holds the deterioration amount for each section of each device, and updates the holding deterioration amount using the calculated difference in the deterioration amount for each section. For railway vehicles that have traveled only in a single section during the period to be processed, that is, from the reception of the previous inspection information to the reception of the current inspection information, the difference in the amount of deterioration is not distributed. Further, when the inspection information includes the deterioration amount of a plurality of inspection dates and times, the related analysis unit 15 similarly distributes the difference in the deterioration amount from the previous inspection to each traveled section for each inspection date and time. do.

Any method may be used to distribute the difference from the deterioration amount. For example, the difference in the deterioration amount is distributed according to the mileage, the running frequency, the terrain, and the like. For example, suppose that a railroad vehicle travels in three sections between the reception of the previous inspection information and the reception of the current inspection information, and the distances of the three sections are 50, 90, and 20, respectively. By ratio, the difference in the amount of deterioration is distributed to each section. Alternatively, if a railroad vehicle travels in four sections and the ratio of traveling frequency is 3: 3: 3: 1, the amount of deterioration and the difference in the amount of deterioration are distributed to each section by this ratio. .. Further, a plurality of items may be combined and distributed, such as combining the terrain and the mileage, or combining the terrain and the mileage. For example, a coefficient to be multiplied by the mileage may be determined according to the progress of deterioration for each terrain, and the difference in the amount of deterioration may be distributed to each section by the ratio of the value obtained by multiplying the mileage by the coefficient.

Next, the related analysis unit 15 obtains the relationship between the mileage and the amount of deterioration as the degree of deterioration for each section. FIG. 16 is a diagram showing an example of the relationship between the mileage for each section and the amount of deterioration calculated by the related analysis unit 15 of the present embodiment. The horizontal axis of FIG. 16 indicates the mileage, and the vertical axis of FIG. 16 indicates the amount of deterioration. The degree of deterioration 201 shown in FIG. 16 indicates the amount of deterioration according to the mileage with respect to the section BM1, and the degree of deterioration 202 indicates the amount of deterioration according to the mileage with respect to the section AK1. For each section, the related analysis unit 15 calculates the relationship illustrated in FIG. 16 by using the amount of deterioration of the equipment of all the railway vehicles traveling in the section and the mileage of the railway vehicle. For example, in the operation information shown in FIG. 7, the trains having the formation number C001 and the formation number C003 are traveling on the route AK on March 19, 2020. Therefore, the railroad vehicles constituting the trains of the formation number C001 and the formation number C003 are traveling in the sections AK1, AK2, and AK3. Therefore, for example, when the related analysis unit 15 calculates the relationship between the mileage for the section AK1 and the maximum wear amount of the slide plate of the pantograph, the related analysis unit 15 of a plurality of railway vehicles including the trains of the formation number C001 and the formation number C003 The amount of deterioration according to the mileage is calculated using the maximum amount of wear of the pantograph's sliding plate. The related analysis unit 15 obtains, for example, the average value, the median value, the mode value, and the like of the deterioration amount (for example, the maximum wear amount of the pantograph sliding plate) of each railroad vehicle according to the mileage for each section. , Find the relationship between the mileage for each section and the amount of deterioration.

Returning to the description of FIG. After step S11, the related analysis unit 15 determines whether or not the degree of deterioration is equal to or less than the reference (step S12). Here, it is assumed that the amount of deterioration is a negative value, the degree of deterioration is also a negative value, and it is assumed that the larger the absolute value of the degree of deterioration is, the greater the degree of deterioration is. Therefore, the smaller the degree of deterioration, which is a negative value, the greater the deterioration, and the fact that the degree of deterioration is below the standard indicates that the deterioration has progressed above the standard. When there are a plurality of sections to be processed, the related analysis unit 15 determines that the degree of deterioration is less than or equal to the reference in step S12 if there is even one section whose degree of deterioration is less than or equal to the reference. The criteria for comparing the degree of deterioration are also referred to as deterioration criteria below. The deterioration standard is a predetermined relationship between the mileage and the amount of deterioration. For example, using inspection information, the average value, the median value, the mode value, etc. of the relationship between the mileage and the degree of deterioration in all sections are used. Is calculated. The entire section referred to here is not only the section in which the railroad vehicle traveled in the inspection information in this processing, but also the entire section in which the railroad vehicle included in all the inspection information received so far has traveled. That is, the entire section referred to here is, for example, the entire section in which the railway vehicle for which the inspection is planned in the inspection plan generated by the inspection plan planning device 1 is assumed to travel. In FIG. 16, the deterioration standard 200 is shown by a broken line. The deterioration standard 200 is determined for each type of deterioration amount, that is, for each inspection item. In the example shown in FIG. 16, since the deterioration degree 201 is lower than the deterioration standard, it is determined that the deterioration degree 201 in the section AK1 is equal to or lower than the deterioration standard. The comparison with the deterioration standard is performed, for example, at a predetermined mileage. For example, in the example shown in FIG. 16, comparison is performed at a mileage of 300.

When the degree of deterioration is equal to or less than the standard (step S12 Yes), the related analysis unit 15 generates deterioration information and notifies the inspection plan generation unit 16 (step S13), and ends the process. In step S13, in detail, the related analysis unit 15 calculates an evaluation index using the degree of deterioration and generates deterioration information including the evaluation index. An example of an evaluation index is a deviation rate indicating the degree of deviation from a standard, that is, a deterioration standard. Hereinafter, the deviation rate from the deterioration standard will be described as an example as an evaluation index, but the evaluation index is not limited to this. As shown in FIG. 16, the deviation rate indicates the difference between the degree of deterioration and the deterioration standard. Specifically, the divergence rate indicates the difference between the degree of deterioration and the deterioration standard as a ratio with a positive or negative sign. For example, the value obtained by subtracting the value of the deterioration standard from the value of the degree of deterioration at a certain mileage is deteriorated. The ratio divided by the standard value is shown as a percentage. The related analysis unit 15 calculates an evaluation index for each section for a section whose deterioration degree is equal to or less than the deterioration standard, and generates deterioration information including the evaluation index for each section. When the deviation rate is a negative value, it indicates that the amount of deterioration is larger than the deterioration standard, and when it is a positive value, it indicates that the amount of deterioration is smaller than the deterioration standard.

FIG. 17 is a diagram showing an example of deterioration information of the present embodiment. In the example shown in FIG. 17, the deterioration information includes identification information indicating an interval, an inspection item, and a corresponding evaluation index.

When the degree of deterioration is not less than or equal to the reference (step S12 No), the related analysis unit 15 ends the process. That is, when there is no section whose deterioration degree is equal to or lower than the reference among the sections to be processed, the related analysis unit 15 ends the processing without generating deterioration information.

Next, the processing in the inspection plan generation unit 16 will be described. The inspection plan generation unit 16 generates an inspection plan using the deterioration information received from the related analysis unit 15. Specifically, for example, the inspection plan generation unit 16 holds the inspection deadline information indicating the correspondence between the value of the evaluation index and the inspection deadline which is the deadline from the latest inspection to the next inspection, and the deterioration information. Generate an inspection plan using the inspection deadline information. That is, the inspection plan generation unit 16 determines the inspection deadline for each combination of sections and inspection items using the inspection deadline information indicating the correspondence between the evaluation index and the inspection deadline and the evaluation index calculated by the related analysis unit 15. Then, an inspection plan is generated using the determined inspection deadline. FIG. 18 is a diagram showing an example of inspection deadline information of the present embodiment. In the example shown in FIG. 18, the above-mentioned divergence rate is used as the inspection index, and if the divergence rate is less than -35%, the inspection is performed within 2 days, and the divergence rate is -35% or more and smaller than -30%. If the divergence rate is -30% or more and less than -25%, the inspection is performed within 5 days, and if the divergence rate is -25% or more, no deadline is set. ing. The inspection deadline information may be set for each inspection item, or common inspection deadline information may be used regardless of the inspection item.

The inspection plan generation unit 16 creates a standard arbitrary inspection plan based on some provisions such as a notification of the Ministry of Land, Infrastructure, Transport and Tourism, and uses the deterioration information to include it in the deterioration information of the inspection plan. An inspection plan is created by modifying the inspection plan so that the corresponding inspection is performed by the inspection deadline determined from the evaluation index for each section and inspection item. Further, the inspection plan generation unit 16 may generate the inspection plan by holding the inspection plan created last time and correcting the part that needs to be corrected by using the deterioration information.

For example, if the deviation rate of the section AK3 is -28% with respect to the wear amount of the pantograph sliding plate, and the previous inspection was 2020/3/20, the section AK3 is within 5 days from 2020/3/20. An inspection plan is generated so that the pantograph slide plate (amount of wear of the slide plate) of the railroad vehicle traveling on the railroad vehicle is inspected.

FIG. 19 is a diagram showing an example of an inspection plan of the present embodiment. As shown in FIG. 19, the inspection plan includes an inspection date and time, a vehicle number, a section scheduled to travel by the inspection date and time, and an inspection item. In the example shown in FIG. 19, the name of the device to be inspected is shown as an inspection item on the premise that the inspection corresponding to one device is performed at the same time. An inspection plan may be set for each of the number of inspection items.

In the above example, the degree of deterioration is calculated for each section, but the cause of deterioration may be analyzed by collectively evaluating the amount of deterioration of sections having the same attributes that classify the sections. For example, for all the sections whose section attributes are mountainous areas, the average value, the maximum value, the mode value, etc. are obtained by using the deterioration amounts of the corresponding plurality of devices in the same manner as the deterioration degree for each section described above. If there is a significant difference in the degree of deterioration for each attribute of the section, it can be seen that the deterioration may progress due to traveling in the mountainous area. In addition, this result may be reflected in the generation of the inspection plan. That is, the inspection plan planning device 1 may generate an inspection plan by using the evaluation index for each attribute instead of the evaluation index for each section.

In the example described above, the inspection planning device 1 is provided in the vehicle base 2 or in the vicinity of the vehicle base 2. Not limited to this, the inspection planning device 1 of the present embodiment may be installed independently of the depot 2. FIG. 20 is a diagram showing a configuration example of a railroad vehicle management system of a modified example of the present embodiment.

Further, in the present embodiment, the degree of deterioration is calculated for each section, the evaluation index is calculated using the degree of deterioration, and the inspection plan is generated using the evaluation index. , The correspondence between the degree of deterioration and the inspection deadline may be directly determined. That is, even if the inspection plan planning device 1 defines the correspondence between the degree of deterioration and the inspection deadline as the inspection deadline information without using the evaluation index, and generates the inspection plan using the degree of deterioration and the inspection deadline information. good. For example, the correspondence between the degree of deterioration corresponding to a specific mileage and the inspection deadline is defined as the inspection deadline information, and the inspection planning device 1 uses the inspection deadline information and the degree of deterioration calculated for each section for a specific run. An inspection plan may be generated with a value corresponding to the distance.

In the example shown in FIG. 20, the inspection planning device 1 is connected to the communication device 6 of the depot 2 via the communication network 7. In FIG. 20, components having the same functions as the components shown in FIG. 1 are designated by the same reference numerals. In the operation of the inspection plan planning device 1 of the present embodiment, the inspection information acquisition unit 11 acquires inspection information from the inspection system 3 via the communication network 7 and the communication device 6, and the inspection plan notification unit 17 receives the inspection information from the communication network. The configuration is the same as that shown in FIG. 1 except that the inspection plan is transmitted to the display terminal 4 via the communication device 6 and the communication device 6. The inspection planning device 1 shown in FIG. 20 is also realized by a computer system in the same manner as the inspection planning device 1 shown in FIG. The inspection planning device 1 shown in FIG. 20 is realized by, for example, a cloud system, but is not limited thereto. As shown in FIG. 20, the communication device 6 may be a device independent of the inspection system 3, or may be provided in the inspection system 3 such as in the analysis device of the inspection system 3. Further, the communication device 6 may be a display terminal 4.

As described above, the deterioration evaluation device of the present embodiment calculates the degree of deterioration indicating the degree of deterioration of the device for each section, calculates the evaluation index using the degree of deterioration, and provides the deterioration information including the evaluation index. Generate. This makes it possible to appropriately evaluate the deterioration of the equipment mounted on the railway vehicle. Further, since the inspection plan planning device 1 which is the deterioration evaluation device of the present embodiment generates an inspection plan using the deterioration information, an appropriate inspection plan reflecting the deterioration state of the equipment mounted on the railroad vehicle can be obtained. Can be planned. Further, when the inspection plan is generated, the inspection plan is created according to the evaluation index of the section to be traveled, so that the inspection plan can be generated according to the state of deterioration expected in the future. Further, since the traveling route is divided into sections according to the terrain and the like, the amount of deterioration according to the attributes of the sections can be calculated, and it becomes easy to separate the causes of deterioration.

Embodiment 2.
FIG. 21 is a diagram showing a configuration example of the railway vehicle management system according to the second embodiment. The railroad vehicle management system of the present embodiment includes a plurality of inspection planning devices 1a and an inspection system 3 provided at each of the plurality of depots. FIG. 21 illustrates each device provided in the depot 2-1 and the depot 2-2, but when the number of depots is 3 or more, the depot 2-1 is also shown in the depots (not shown). Each device is provided in the same manner as above. The number of depots may be 2 or more, and there is no particular limitation. Components having the same functions as those in the first embodiment are designated by the same reference numerals as those in the first embodiment, and duplicate description will be omitted. Hereinafter, the points different from those of the first embodiment will be mainly described. Hereinafter, the depot may be abbreviated as a base, and the railroad vehicle may be abbreviated as a vehicle.

As shown in FIG. 21, the depot 2-1 is provided with the same inspection system 3 and display terminal 4 as in the first embodiment, and is provided with the inspection plan planning device 1a instead of the inspection plan planning device 1. Similarly, the depot 2-2 is also provided with an inspection system 3, a display terminal 4, and an inspection planning device 1a. Further, when the plurality of depots are three or more depots, the inspection system 3, the display terminal 4, and the inspection planning device 1a are similarly provided in other depots (not shown). In the inspection plan planning device 1a, the inter-base cooperation unit 18 is added to the inspection plan planning device 1 of the first embodiment, and the inspection plan generation unit 16a is provided instead of the inspection plan generation unit 16. The components other than the inter-base cooperation unit 18 and the inspection plan generation unit 16a in the inspection plan planning device 1a are implemented except that the input / output due to the cooperation operation between a plurality of vehicle bases is partially changed as described later. It is the same as the form 1 of.

The inspection information acquisition unit 11, the inspection information storage unit 12, the related information acquisition unit 13, the related information storage unit 14, and the related analysis unit 15 of the present embodiment are deterioration evaluation devices for evaluating deterioration as in the first embodiment. To configure. In the present embodiment, the inspection plan planning device 1a, which is a deterioration evaluation device, also has a function of generating an inspection plan.

The inter-base cooperation unit 18 of the present embodiment receives deterioration information from the related analysis unit 15, and based on the deterioration information, another vehicle base where railroad vehicles traveling in the same section or similar sections as the section with large deterioration stop. Notify the deterioration information to the inspection planning device 1a of the above. The similar section is, for example, a section in which a part of the section is shared when there is a section in which the degree of deterioration of the device is larger than that of the reference. Further, when the inter-base cooperation unit 18 receives deterioration information from the inspection plan planning device 1a at another depot, the inter-base cooperation unit 18 notifies the inspection plan generation unit 16a of the received deterioration information. That is, the inter-base cooperation unit 18 transmits deterioration information to another deterioration evaluation device provided at another depot and uses the deterioration information to generate an inspection plan for a railroad vehicle, and the other deterioration evaluation device causes the other deterioration evaluation device. Receives deterioration information indicating the degree of deterioration of the equipment mounted on the rail yard for each section calculated by the deterioration evaluation device.

When the number of vehicle bases is 3 or more, the illustration is omitted in FIG. 21, but for example, the inter-base cooperation unit 18 in the inspection plan planning device 1a of the vehicle base 2-1 is other than the vehicle base 2-2. It is possible to communicate with the inter-base cooperation unit 18 in the inspection planning device 1a provided at the base of the above. Similarly, the inter-base cooperation unit 18 in the inspection planning device 1a provided at each depot can communicate with the inter-base cooperation unit 18 in the inspection planning device 1a provided at another depot. It is not necessary for the inter-base cooperation unit 18 to perform communication between some depots, such as between depots where vehicles traveling on the same route or similar routes do not stop.

In the present embodiment, the related analysis unit 15 generates deterioration information in the same manner as in the first embodiment, outputs the generated deterioration information to the inspection plan generation unit 16a, and outputs the generated deterioration information to the inter-base cooperation unit 18.

The operation of the inter-base cooperation unit 18 will be described. FIG. 22 is a flowchart showing an example of the processing procedure in the inter-base cooperation unit 18 of the present embodiment. When the inter-base cooperation unit 18 acquires deterioration information from the related analysis unit 15 (step S21), it determines whether a vehicle traveling in the same or similar section exists at another base, that is, another vehicle base (step S22). .. In step S22, the inter-base cooperation unit 18 travels in the same or similar section as the vehicle stopped at the depot where the inspection planning device 1a including the inter-base cooperation unit 18 is installed, using the operation information and the organization information. Determine if there is another depot where the vehicle is parked. The operation information also includes information indicating which vehicle base each train stops at.

When a vehicle traveling in the same or similar section exists at another base (step S23 Yes), the inter-base cooperation unit 18 transmits deterioration information to the other base (step S24), and ends the process. Specifically, in step S24, inspection planning is made at another depot where a vehicle traveling in the same or similar section as the vehicle stopped at the depot where the inspection planning device 1a including the inter-base cooperation unit 18 is installed is stopped. Deterioration information is transmitted to the device 1a. When there is no vehicle traveling in the same or similar section at another base (step S23 No.), the inter-base cooperation unit 18 ends the process without executing step S24.

Further, the inter-base cooperation unit 18 performs the processing shown in FIG. 22, and when it receives deterioration information from the inspection plan planning device 1a at another depot, notifies the inspection plan generation unit 16a of the received deterioration information.

Note that the deterioration information may be transmitted to the inspection planning device 1a at all the depots without carrying out the above-mentioned steps S22 and S23. Alternatively, if a plurality of vehicle bases on which railroad vehicles traveling in the same section or similar sections are stopped are known in advance, the inter-base cooperation unit 18 is deteriorated so as to transmit and receive deterioration information between these vehicle bases. By setting the information transmission destination, the above-mentioned steps S22 and S23 may be omitted. Alternatively, the operator specifies another vehicle base where the railway vehicle traveling in the same section or a similar section stops, so that the inter-base cooperation unit 18 can specify the deterioration information without performing steps S22 and S23. It may be transmitted to the inspection planning device 1a at the depot.

Next, the operation of the inspection plan generation unit 16a will be described. FIG. 23 is a flowchart showing an example of the processing procedure in the inspection plan generation unit 16a of the present embodiment. The inspection plan generation unit 16a acquires deterioration information from the related analysis unit 15 as in the first embodiment (step S31). The inspection plan generation unit 16a determines whether or not deterioration information has been received from another base (step S32). Specifically, the inspection plan generation unit 16a determines whether or not the deterioration information transmitted from the other base is received from the inter-base cooperation unit 18. When the inter-base cooperation unit 18 at a certain depot receives deterioration information from the related analysis unit 15, the deterioration information is not always generated and transmitted at another depot. Therefore, the inspection plan generation unit 16a may determine Yes in step S32 if, for example, the deterioration information has been received even once in the past. Then, the inspection plan generation unit 16a adopts the latest deterioration information when the deterioration information is received a plurality of times from the same depot. However, if more than a certain period of time has passed since the deterioration information was received from another depot, the condition may have changed due to equipment replacement, maintenance, etc., so the deterioration Information may not be adopted.

When the deterioration information is not received (step S32 No), the inspection plan generation unit 16a generates an inspection plan using the deterioration information acquired from the related analysis unit 15 as in the first embodiment (step S35). , The inspection plan is notified to the inspection plan notification unit 17 (step S34), and the process is terminated.

When the deterioration information is received from another base (step S32 Yes), the inspection plan generation unit 16a generates an inspection plan using the deterioration information acquired from the related analysis unit 15 and the deterioration information received from the other base (step S32 Yes). S33), the process proceeds to step S34. Specifically, in step S33, the related analysis unit 15 performs the following processing, for example. For example, the degree of urgency for each section and inspection item is divided into levels based on the evaluation index for each section and inspection item included in the deterioration information.

FIG. 24 is a diagram showing an example of the level of urgency of the present embodiment. In the example shown in FIG. 24, the urgency is shown in four stages from level 0 to level 3, and the larger the level value, the higher the urgency of the inspection. In the example shown in FIG. 24, the level is defined according to the value of the evaluation index, and the inspection deadline corresponding to the level is set. The inspection plan generation unit 16a obtains the urgency level for each section and inspection item based on the correspondence illustrated in FIG. 24 by using the deterioration information acquired from the related analysis unit 15 and the deterioration information received from another base. Then, the inspection plan generation unit 16a sets the first urgency, which is the urgency based on the deterioration information acquired from the related analysis unit 15, for each section and inspection item, with the urgency based on the deterioration information received from other bases. Correct with a second degree of urgency. For example, the inspection plan generation unit 16a raises the first urgency by one level when the second urgency is higher than the first urgency. For example, the inspection plan generation unit 16a of the depot 2-1 obtains the urgency of the wear amount of the pantograph sliding plate for the section AK3 based on the deterioration information acquired from the related analysis unit 15, and the obtained urgency is level 1. Suppose it was. Then, the inspection plan generation unit 16a of the depot 2-1 obtains the urgency of the amount of wear of the pantograph sliding plate for the section AK3 based on the deterioration information received from the depot 2-2, and the obtained urgency is the level. Suppose it was 2. In this case, the inspection plan generation unit 16a raises the first urgency level 1 by one level to level 2. Also, if the second urgency is equal to the first urgency or if the second urgency is lower than the first urgency, the first urgency is not changed. In this case, the first urgency becomes the corrected first urgency as it is.

The inspection plan generation unit 16a uses the first urgency after the correction using the second urgency, and the correspondence between the level illustrated in FIG. 24 and the inspection deadline, and the first embodiment. Similarly, generate an inspection plan. When the inspection plan generation unit 16a receives deterioration information from a plurality of other bases, the inspection plan generation unit 16a calculates a second urgency for each vehicle base, and even one of the plurality of second urgency is the first urgency. If there is something higher than the degree, a correction is made to raise the first urgency by one level.

Alternatively, the inspection plan generation unit 16a may determine the degree of urgency by the following processing. First, the inspection plan generation unit 16a may obtain the first urgency and the second urgency, and generate the inspection plan using the highest level among them, as in the above-mentioned example. FIG. 25 is a diagram showing an example of the degree of urgency corresponding to each depot of the present embodiment. FIG. 25 shows an example of the first urgency and the second urgency calculated by the depot 2-1. As shown in FIG. 25, the first urgency is level 1 and the second urgency. The urgency corresponding to the depot 2-2, which is one of the urgency levels of, is level 2, and the urgency corresponding to the depot 2-3, which is one of the second urgency levels, is level 2. It is 1. In this case, the inspection plan generation unit 16a may generate the inspection plan by adopting the highest level 2 among these urgency levels.

As described above, in the present embodiment, by sharing the deterioration information between the depots, the deterioration tendency that could not be grasped only by the inspection information acquired at the single depot becomes clear. The accuracy of the evaluation is improved, and it becomes possible to more appropriately inspect the vehicle having a high possibility of deterioration in the future as compared with the first embodiment.

The inspection plan planning device 1a of the present embodiment is realized by a computer system in the same manner as the inspection plan planning device 1 of the first embodiment. The inter-base cooperation unit 18 is realized by, for example, the communication unit 105 of FIG.

In the example shown in FIG. 21, an inspection plan planning device 1a is provided at each depot, but inspection information is collected from a plurality of depots and inspection plans for a plurality of depots are generated using these inspection information. May be done. FIG. 26 is a diagram showing a configuration example of a railroad vehicle management system of a modified example of the present embodiment. In the rail yard management system of the present embodiment, similarly to the vehicle base 2 of the modified example shown in FIG. 20 of the first embodiment, the vehicle base 2-1 includes a communication device 6, an inspection system 3, and a display terminal 4. Is provided. Similarly, the communication device 6, the inspection system 3, and the display terminal 4 are provided in the depot 2-2 and other depots (not shown). The railroad vehicle management system of the modified example of the present embodiment includes an inspection planning device 1b connected to a communication device 6 of each depot via a communication network 7. The inspection plan planning device 1b includes an inter-base cooperation unit 18 instead of the inspection information acquisition unit 11 and the inspection plan notification unit 17, and an inspection plan generation unit 16b instead of the inspection plan generation unit 16. This is the same as the inspection planning device 1 of the modified example shown in FIG. 20 of FIG.

The inter-base cooperation unit 18 of the inspection plan planning device 1b acquires inspection information from the inspection system 3 via the communication device 6 of each depot and stores it in the inspection information storage unit 12. That is, the inter-base cooperation unit 18 of the inspection planning device 1b receives inspection information from a plurality of inspection systems 3 provided at each of the plurality of depots. The related analysis unit 15 uses the inspection information of the plurality of inspection systems 3 received by the inter-base cooperation unit 18 to generate deterioration information for each section as in the first embodiment. At this time, the inspection information used by the related analysis unit 15 is the inspection information of a plurality of depots, but the method of generating the deterioration information itself is the same as that of the first embodiment. The inspection plan generation unit 16b obtains a railroad vehicle scheduled to stop at the depot based on the operation information for each depot, and uses the inspection deadline corresponding to the section in which the railroad vehicle is scheduled to travel. In the same manner as above, an inspection plan is generated and notified to the inter-base cooperation unit 18. The inter-base cooperation unit 18 notifies the display terminal 4 of the corresponding vehicle base of the inspection plan via the communication network 7 and the communication device 6. In the modified example shown in FIG. 26, deterioration information can be generated using inspection information acquired from a plurality of depots, so that deterioration of each section can be evaluated more accurately than in the first embodiment. can. As a result, as compared with the first embodiment, it becomes possible to more appropriately inspect the vehicle having a high possibility of deterioration in the future with priority.

Further, the method of generating deterioration information and the method of generating an inspection plan in the modified example shown in FIG. 26 are not limited to the example described in the first embodiment. For example, the related analysis unit 15, the related information acquisition unit 13 and the related information storage unit 14 are deleted from the inspection plan planning device 1b shown in FIG. 26, and the inspection plan generation unit 16b obtains the inspection information acquired at each depot. It may be used to generate an inspection plan based on the latest value of the deterioration amount for each device included in each inspection information. In this case, the inspection plan generation unit 16b holds, for example, the correspondence between the deterioration amount and the inspection deadline for each type of equipment, and corresponds to the latest value of the deterioration amount for each equipment included in each inspection information. Generate an inspection plan at each depot to meet the inspection deadline. In this case as well, deterioration can be evaluated more appropriately than when the conventional inspection information of one depot is used, and a more appropriate inspection plan that reflects the deterioration state of the equipment mounted on the railway vehicle can be obtained. Can be planned. In this way, the inspection planning device 1b provides inspection information indicating the amount of deterioration of the equipment mounted on the railroad vehicle obtained by the visual inspection of the railroad vehicle from the plurality of inspection systems 3 provided at each of the plurality of depots. An inspection plan generation unit that generates an inspection plan for visual inspection at a plurality of depots using a plurality of inspection information corresponding to each of the receiving inter-base cooperation unit 18 and the plurality of vehicle bases received by the inter-base cooperation unit 18. 16b and the like may be provided.

As described above, in the present embodiment, by sharing the information between the depots, the same effect as in the first embodiment can be obtained, and it can be grasped only by the inspection information acquired at the single depot. Since the deterioration tendency that did not exist is clarified, the accuracy of deterioration evaluation is improved, and it becomes possible to more appropriately inspect vehicles that are likely to deteriorate in the future as compared with the first embodiment. ..

Embodiment 3.
FIG. 27 is a diagram showing a configuration example of the railway vehicle management system according to the third embodiment. As shown in FIG. 27, the railroad vehicle management system of the present embodiment includes an inspection planning device 1c, an inspection system 3, and a display terminal 4. In the example shown in FIG. 27, the railroad vehicle management system is provided at the depot 2, but the installation position of the railroad vehicle management system is not limited to this example. Components having the same functions as those in the first embodiment are designated by the same reference numerals as those in the first embodiment, and duplicate description will be omitted. Hereinafter, the points different from those of the first embodiment will be mainly described.

The inspection planning device 1c of the present embodiment acquires external information such as meteorological data, terrain data, and the number of passengers from the external system 8, and updates the deterioration standard for each section using the external information. As a result, the characteristics of each section can be taken into consideration, the deterioration state can be grasped more accurately, and an efficient inspection plan can be formulated.

As shown in FIG. 27, the inspection plan planning device 1c includes an external information acquisition unit 19, an external information storage unit 20, and a reference data generation unit 21 in the inspection plan planning device 1 of the first embodiment. The external information acquisition unit 19 acquires external information from the external system 8 and stores the acquired external information in the external information storage unit 20. The external system 8 is an external system that responds to external information, is a system that provides meteorological data when the external information is meteorological data, and provides topographical data when the external information is topographical data. It is a system that provides the number of passengers when the external information is the number of passengers. When the external information is the number of passengers, the operation management system 5 may also serve as the external system 8. Further, instead of the number of passengers, as information indicating the number of passengers, the measurement result of the air spring pressure measured by the train, the camera image, the number of people passing through the ticket gate of the station, or the like may be used. When the external information is the number of passengers itself, the external information is, for example, the sales record of the ticket, the number of reservations, and the like, but is not limited thereto.

When the measurement result of the air spring pressure measured by the train is used as the information indicating the number of passengers, the external system 8 acquires the data indicating the output of the air spring for each date and time from the train, and uses the acquired data as the information of the train. It is provided to the inspection planning device 1c together with the organization number. When a camera image is used as information indicating the number of passengers, the camera image may be acquired by a camera installed on the platform of the station, or may be acquired by a camera installed inside the train. It may be a new one. When the camera image acquired by the camera installed on the platform of the station is used, the person captured in the camera image by associating the acquired date and time of the camera image with the train using the train operation schedule. The number of passengers on each train can be estimated using the number of. Even when the number of people who have passed the ticket gate of a station is used as information indicating the number of passengers, the number of passengers of each train can be estimated by associating the date and time with the train using the train operation schedule.

When the external information is a plurality of types of data and the system that provides the data is different for each type, the external system 8 includes a plurality of systems. The external information is, for example, at least one of, but is not limited to, meteorological data, terrain data and the number of passengers. For example, external information includes track information, track (rail) wear degree, track deterioration degree, track inspection history / replacement history, railway equipment (trolley line) inspection history / replacement history, sports games, exhibitions, etc. It may be event information in which the flow of people changes, information indicating the work shift of inspectors, information related to geological phenomena (sediment disaster, earthquake forecast, tsunami warning), and the like.

When track information is used as external information, the inspection plan planning device 1c sets deterioration standards so that, for example, a vehicle running in a section with a lot of vibration such as an iron bridge can be prioritized to formulate an inspection plan. Further, when the degree of wear of the track, the degree of deterioration of the track, the inspection history / replacement history of the track, and the inspection history / replacement history of railway equipment are used as external information, the inspection planning device 1c is deteriorated or worn, for example. Deterioration standards are set so that inspection plans can be made with priority given to vehicles running in sections that are in operation and sections that have not been inspected or replaced for a long period of time. When event information is used as external information, the inspection plan planning device 1c sets a deterioration standard so that, for example, a vehicle running in a section corresponding to the event can be prioritized to formulate an inspection plan before the event. do. When using information related to geological phenomena as external information, the inspection plan planning device 1c sets deterioration standards so that, for example, vehicles running in sections damaged by earthquakes and tsunamis can be prioritized to formulate inspection plans. Set. Further, the external information may be directly reflected in the drafting of the inspection plan instead of being used for determining the deterioration standard. For example, when the event information is used as the external information, the inspection plan planning device 1c formulates an inspection plan so that the vehicle running in the section corresponding to the event is inspected before the event. In addition, when information indicating the work shift of an inspector is used as external information, it is considered that the inspection cannot be performed and the deterioration cannot be grasped during the period when there is no inspector, and the deterioration is progressing. 1c formulates an inspection plan so as to give priority to inspection of uninspected railway vehicles and the like.

In the following, the case where the external information is meteorological data, topographical data, and the number of passengers will be described as an example. It is assumed that the meteorological data includes the temperature at each date and time for each district, and the topographical data includes the altitude, gradient, etc. for each district. Further, the number of passengers may be the average number of passengers for each section or route, or the number of passengers for each section or route may be indicated for each date and time.

The external information storage unit 20 is external to the deterioration standard, such as first correspondence information indicating the correspondence between the device and information affecting the deterioration of the device, second correspondence information for calculating the geographical position of each section, and the like. Various correspondence information used for reflecting data is stored. The information that affects the deterioration of the device is the information included in the external information or the information calculated from the external information. The first correspondence information determines the type of external data to be considered in the generation of deterioration criteria for each device. The second correspondence information is, for example, information indicating the correspondence between the section and the geographical section in the meteorological data and the topographical data. The first correspondence information and the second correspondence information may be input to the inspection planning device 1c by an operator or the like by an input receiving unit (not shown), or may be transmitted from another device (not shown).

Inspection information acquisition unit 11, inspection information storage unit 12, related information acquisition unit 13, related information storage unit 14, related analysis unit 15, external information acquisition unit 19, external information storage unit 20, and reference data generation unit of the present embodiment. 21 constitutes a deterioration evaluation device for evaluating deterioration. In the present embodiment, the inspection plan planning device 1c, which is a deterioration evaluation device, also has a function of generating an inspection plan.

FIG. 28 is a diagram showing an example of the first correspondence information of the present embodiment. As shown in FIG. 28, in the first correspondence information, the device and the information affecting the deterioration of the device (abbreviated as the information affecting the device in the figure) are associated with each other. The first correspondence information shown in FIG. 28 shows that when the device is a panda flag slide, the average gradient and temperature affect the deterioration, and when the device is a wheel, the average number of passengers affects the deterioration. ing. FIG. 28 is an example, and the correspondence between the device and the information affecting the deterioration of the device is not limited to the example shown in FIG. 28.

FIG. 29 is a diagram showing an example of the second correspondence information of the present embodiment. In the second correspondence information shown in FIG. 29, the section is associated with the geographical section in each of the meteorological data and the topographical data. Here, it is assumed that the meteorological data is distributed as information for each district such as A district and B district, and the topographical data is distributed as information for each district such as a district and b district. For example, in the example shown in FIG. 29, the section AK1 corresponds to the area A in the meteorological data and corresponds to the areas a and b in the topographical data.

Further, the second correspondence information is not limited to the example shown in FIG. 29, and may be information indicating the correspondence between the station position and the section. FIG. 30 is a diagram showing another example of the second correspondence information of the present embodiment. In the second correspondence information shown in FIG. 30, the station ID, which is the identification number of the station, the geographical position of the station, and the section to which the station belongs are associated with each other. In the example shown in FIG. 30, the position of the station is indicated by latitude and longitude, which makes it possible to associate the terrain data and the meteorological data with each station. For example, meteorological data and topographical data within a range defined from each station, such as a range within a radius of 1 km from each station, can be used as meteorological data and topographical data for the section to which the station belongs.

Further, as the second correspondence information, position information indicating the position of the railway vehicle obtained by a GPS (Global Positioning System) receiver mounted on the railway vehicle or the like may be used. In this case, the second response information is provided by a system that collects information from the railcars. This system may be the operation management system 5 described above.

FIG. 31 is a diagram showing still another example of the second correspondence information of the present embodiment. In the second correspondence information shown in FIG. 31, the organization number is associated with the date and time and the information indicating the position. By using the formation number, the date and time, and the traveling information described in the first embodiment, it is possible to associate the date and time and position of each train with the corresponding section. For example, meteorological data and terrain data in a range within a predetermined distance from each position, such as a range within a radius of 1 km of a position obtained from each train, can be used as information on the corresponding section.

The reference data generation unit 21 of the present embodiment generates a deterioration standard by the same method as that of the first embodiment, and the generated deterioration standard is stored in the external information storage unit 20 for each section. And the deterioration standard is generated by making corrections using the corresponding information. For example, the reference data generation unit 21 first calculates the information used for correcting the deterioration standard of each section by using the external data and the first correspondence information. As shown in FIG. 28, when the average gradient, the temperature, and the average number of passengers are used, the reference data generation unit 21 obtains the average gradient using the terrain data and the temperature using the meteorological data for each section. Find the average number of passengers. The gradient used to calculate the average gradient may be calculated by calculating the rate of change in elevation using the elevation of each area included in the terrain data, or the gradient of each area included in the terrain data may be used. You may. If there are areas with different temperatures within the section, the average or median temperature within the section is used. Regarding the average number of passengers, if the average number of passengers for each section is provided as external information, the external information can be used as it is, but the reference data generation unit 21 uses the reference data generation unit 21 as external information for each section for each date and time. When input as the number of passengers, the reference data generation unit 21 obtains the average value of the number of passengers for each section.

When the number of passengers for each route is provided as external information, the reference data generation unit 21 uses the average number of passengers for each route as the average number of passengers for the section belonging to the route. In addition, when information indicating the air spring pressure is provided instead of the number of passengers, the information indicating the air spring pressure is provided for each section by using the formation number and the date and time corresponding to the air spring pressure and the operation information or the running information. Correspond to. Then, the reference data generation unit 21 holds a coefficient for converting the air spring pressure into the number of passengers, converts the information indicating the air spring pressure in each section into the number of passengers using the coefficient, and averages each section. Find the number of passengers.

Since the average gradient of each section is basically unchanged once it is calculated, the average gradient of each section may be held as a table. FIG. 32 is a diagram showing an example of a table showing the average gradient for each section of the present embodiment. The reference data generation unit 21 may obtain the average gradient of each section using the terrain data, and may hold it as a table together with the total distance for each section, for example, as shown in FIG. 32. The calculated average distance may be added to the section information described in the first embodiment, and the table shown in FIG. 32 may be retained as the section information. In this case, the reference data generation unit 21 calculates the average gradient of each section with reference to the section information when correcting the deterioration standard.

Here, the information that affects the deterioration of each device calculated based on the external information may include the number of curves in each section, the curvature of the curves, the weather, etc., in addition to the above-mentioned example. , Information other than those described above may be included.

As described above, the reference data generation unit 21 calculates the information affecting the deterioration, and indicates the deterioration standard calculated by the same method as in the first embodiment in the first correspondence information for each section and device. Correct using the information that affects the deterioration. For example, the amount of wear of the sliding plate of the pantograph is expected to increase as the average gradient increases. Therefore, the ratio of the average gradient of each section to the average value of all sections of the average gradient is the same as in the first embodiment. Multiply each reference value of the deterioration standard regarding the amount of wear of the sliding plate of the pantograph calculated by the method of. For example, suppose that the average gradient G _{ALL of} all sections is 10, the average gradient G _AK3 of section AK3 is 15, and the average gradient G _{AK1 of} section AK1 is 8. In this case, when the deterioration standard calculated by the same method as in the first embodiment is _RALL (D), the reference data generation unit 21 determines the deterioration standard R _AK3 (D) of the section AK3 and the deterioration standard R of the section AK1. _AK1 (D) is calculated by the following equations (1) and (2). Note that D indicates the mileage, and _{(D) of R ALL} (D), R _AK1 (D) and R _AK3 (D) indicates that these are functions of the mileage.
R _AK3 (D) = (G _AK3 / G _ALL ) x R _ALL (D) ... (1)
R _AK1 (D) = (G _AK1 / G _ALL ) x R _ALL (D) ... (2)

Similarly, regarding the air temperature, it is expected that the higher the temperature, the greater the amount of wear of the pantograph sliding plate. Therefore, the ratio of the air temperature in each section to the average value of all the sections of the air temperature is the same as in the first embodiment. Multiply each reference value of the deterioration standard regarding the amount of wear of the sliding plate of the pantograph calculated by the method of. Since the air temperature changes depending on the date and time, the average value of the air temperature in the train operating time zone from the previous inspection to the latest inspection may be used, or the maximum air temperature may be used.

Further, since it is expected that the amount of wheel flange wear increases as the average number of passengers increases, the ratio of the average number of passengers in each section to the average value of the average number of passengers in all sections is calculated by the same method as in the first embodiment. Multiply each reference value of the deterioration standard regarding the amount of flange wear of the wheel calculated in.

As described above, the reference data generation unit 21 generates a deterioration standard for each section and outputs it to the related analysis unit 15. FIG. 33 is a diagram showing an example of a deterioration standard generated by the reference data generation unit 21 of the present embodiment. As shown in FIG. 33, the deterioration standard data according to the mileage is generated for each section and inspection item by the above-mentioned processing by the reference data generation unit 21. Then, the related analysis unit 15 generates deterioration information in the same manner as in the first embodiment by using the deterioration standard received from the reference data generation unit 21. The operations of the present embodiment other than those described above are the same as those of the first embodiment. In the present embodiment, the same effect as that of the first embodiment can be obtained, and the following effects can be obtained by using the deterioration standard according to the mileage. Since it is assumed that the amount of deterioration tends to increase in the section where the deterioration is severe, if the same deterioration standard is used for all sections, it may be determined that there is some abnormality and the inspection interval may be shortened. On the other hand, in a section where deterioration is severe, it is not an abnormality that the absolute value of the amount of deterioration increases to some extent, but it is expected deterioration. It is possible to prevent the inspection interval from becoming shorter than necessary. This makes it possible to formulate an appropriate inspection plan.

In the present embodiment, information that affects deterioration is given in advance for each device as the first correspondence information, but a trained model is generated by machine learning using external information and inspection information, and the trained model is generated. It may be used to correct the deterioration standard for each device. The reference data generation unit 21 obtains, for example, the average value of the deterioration amount according to the mileage as the average deterioration amount by using the deterioration degree of all the sections included in the inspection information. Then, the reference data generation unit 21 obtains the deterioration amount for each device by adding the difference in the deterioration amount from the previous inspection as described in the first embodiment, and obtains the deterioration amount for each device and the deterioration amount. The difference from the average deterioration amount of the mileage corresponding to is obtained as the teacher data. Then, each information to be used as input information is calculated by using the external information of the period corresponding to the inspection information. The input information is, for example, the average gradient, the average number of passengers, the temperature, the weather, and the like. The reference data generation unit 21 uses the calculated input information and the corresponding teacher data as a set of data sets, and performs supervised learning using a plurality of data sets for each section, thereby deteriorating the amount of deterioration in each section. It is possible to learn the relationship between the difference between and the average deterioration amount and the input information. After generating the trained model, the reference data generation unit 21 inputs the input information of the period corresponding to the inspection information into the trained model of each section from the average deterioration amount of the deterioration amount of each section. The difference can be inferred. The reference data generation unit 21 can correct the deterioration reference by using the difference obtained by the inference.
