Description

The present invention relates to a maintenance work plan support device and a maintenance work plan support method.

In transportation such as railroads, proper maintenance of operating vehicles and equipment is indispensable for realizing safe transportation. Maintenance work is planned and executed from the viewpoint of preventive maintenance according to the target equipment. As a technique for supporting the creation of such a maintenance work plan, there is a technique described in Patent Document 1. This technology discloses a method for automatically planning efficient maintenance work based on the number of equipment installations and the number of defects while considering train schedules. Specifically, the maintenance work plan creation system described in the document is a maintenance work target by obtaining a value obtained by multiplying each equipment state by weighting from equipment inspection records and weighting information according to the equipment state. A maintenance work plan is created by extracting the equipment to be used, the status of the equipment, information on the route / station to which the equipment belongs, and the time zone during which maintenance work is possible from the train schedule.

Japanese Patent No. 6192545

The technique described in Patent Document 1 extracts a time zone during which maintenance work can be performed without changing the planned train schedule so as not to interfere with train operation. Conventionally, midnight from the last train to the first train To improve the inefficiency of work due to the time constraint of maintenance work that is often performed during the time period (work preparation and withdrawal are required after the last train to before the first train regardless of the target and content of maintenance work) I can't make a good plan.

That is, when the maintenance work requires a longer time than the time from the last train to the first train, it is necessary to withdraw once before the first train and restart the work after the last train, which causes extra withdrawal and re-preparation work. However, no plan can be made to improve such inefficiencies. In addition, if the work takes time, or if an unexpected event occurs and the work time is longer than originally planned, the work that should have been completed between the last train and the first train cannot be completed. It is possible that the first train will be forced to suspend operations unplanned. However, the technique of Patent Document 1 cannot make a plan to improve this problem.

Therefore, one object of the present invention is to provide a maintenance work plan support device and a maintenance work plan support method that realize the incorporation of maintenance work into the daytime train operation time zone while suppressing the influence on transportation.

In order to solve the above problems, the maintenance work plan support device according to one aspect of the present invention is configured as a computer having a processor and a memory for storing data used by the processor, and is a maintenance work plan for equipment related to railway lines. Information on the operation plan storage unit that stores the operation plan information of the train operated on the railway line and the number of users transported by the train operated on the railway line, which is a device for supporting the planning of A maintenance target that stores maintenance target information including a transportation record storage unit that stores transportation record information, section information that is information about routes and sections that are subject to maintenance work, and information on the time required for the maintenance work. When the maintenance work is carried out in the train operating time zone by referring to either or both of the operation plan information and the transportation record information based on the storage unit and the section information and the required time information, the section The maintenance work is performed based on the transportation impact calculation processing unit that calculates the transportation impact degree, which is an index indicating the degree of influence on the transportation of the user who uses the section specified by the information, and the calculated transportation impact degree. It is provided with a maintenance time zone candidate extraction processing unit that extracts candidates for maintenance work time zones, which are time zones to be implemented.

According to one aspect of the present invention, it is possible to formulate a maintenance work plan that incorporates maintenance work during the daytime train operating hours while suppressing the influence on transportation.

Specifically, the train operation schedule is grasped from the operation plan information, the station where the passenger got on and off and the date and time of getting on and off are grasped from the transportation record information, and the route, section and maintenance work time required for maintenance are grasped from the maintenance construction information. , The time zone that has less influence on the passengers who use the route or section to be maintained is extracted as the maintenance work time zone candidate.

The operation plan information management device 20 is a device that manages train plan schedule information. For each train scheduled to operate in the future, the train number that identifies each train, the train type, the running route, the departure / arrival number / arrival / departure time of the stop station, etc. are managed, and in this embodiment, the maintenance work plan support device 10 is maintained. It is used as information for narrowing down work time zone candidates. FIG. 4 shows an example of the operation plan information stored in the operation plan information management device 20. The train operation information in FIG. 4 indicates that an ordinary train (local train) with train number 101 operated on the X-ray line departs from A station at 7:00 and operates to C station. Such train operation information is stored in the operation plan information management device 20 for all trains on all routes. From this train operation information, it is possible to know how many trains are operated in a specific time zone for a specific section of a certain line.

The transportation record information management device 30 is a device that manages boarding / alighting history information of passengers who use trains. The boarding / alighting history information referred to here refers to boarding / alighting history information collected and accumulated from a station ticket gate or the like via a communication network when using transportation using an IC card type electronic ticket. Electronic tickets can be used in various means of transportation such as buses, taxis, and share bikes in addition to trains. In addition to the fare used, the station / stop where you boarded / disembarked and the date and time of boarding / alighting are used as boarding / alighting history information. It is recorded in the transportation record information management device 30 through a station ticket gate or the like. FIG. 5 shows an example of the transportation record information stored in the transportation record information management device 30. The transportation record information of FIG. 5 records each item of the date of use, the admission record, and the participation record in association with the ticket ID that identifies each electronic ticket. This indicates that the holder of the electronic ticket specified by 0001 entered at 8:10 at station A and participated at 8:30 at station B on May 10, 2019. This transportation record information is recorded each time it is used for all issued ticket IDs. This makes it possible for the holder of a specific ticket ID to know which route is used at what time zone. In the present embodiment, this transportation record information is used as information for obtaining the degree of transportation influence used for extracting maintenance work time zone candidates. The degree of transportation impact will be described later.

The maintenance construction information management device 40 is a device that comprehensively manages maintenance-related information of railway equipment. Specifically, in addition to the maintenance work time required according to the maintenance target route, section, and maintenance content described above, inspection results for determining maintenance necessity, maintenance construction instructions and construction according to the inspection results. Manage various information related to maintenance work such as construction contracts and budget management required for construction. FIG. 6 shows an example of maintenance / construction information stored in the maintenance / construction information management device 40. The maintenance work information of FIG. 6 is an example specialized in the information used by the maintenance work plan support device 10 of the present embodiment, and is a work content representing the content of the maintenance work, a work unit representing the implementation unit of the maintenance work, and maintenance. The standard values for daytime and late-night work costs are recorded. In the case of FIG. 6, when the rail exchange is carried out over 100 m, the cost in that case is MMM yen in the daytime and mmm yen in the middle of the night. In the present embodiment, this information is used for daytime and midnight maintenance cost calculation and comparison according to the route, section, and content of the maintenance work included in the maintenance target information described later.

The above operation plan information, transportation record information, and maintenance / construction information are all examples of the configuration, and it is appropriate to include record items other than the above or change the contents of the above record items. can do.

In the present embodiment, the business operation terminal 50 is a terminal device used by a person in charge of creating a maintenance work plan to operate the maintenance work plan support device 10. To access the maintenance work plan support device 10, a person-in-charge application embedded in the business operation terminal 50 or a general Web browser can be used.

Configuration of Maintenance Work Plan Support Device 10 Next, the functional configuration of the maintenance work plan support device 10 according to the present embodiment will be described. FIG. 2 is a diagram showing a functional configuration example of the maintenance work plan support device 10. The maintenance work plan support device 10 in the present embodiment includes a communication processing unit 110 that communicates with an external device or terminal via a communication network N, and operation plan information, transportation record information, and maintenance work described with reference to FIG. The maintenance work is performed based on the transportation impact calculation processing unit 120 that calculates the transport impact degree, which is an index indicating the degree of influence on the transport by carrying out the maintenance work using the information, and the calculated transport impact degree. It includes a maintenance time zone candidate extraction processing unit 130 for extracting maintenance time zone candidates to be executed, and a control processing unit 140 for controlling data processing in these processing units.

Further, the maintenance work plan support device 10 has an operation plan storage unit 150 and a transportation record storage unit 160 as storage areas for storing data used by the processing unit, data output after the processing is executed by the processing unit, and the like. , Maintenance target storage unit 170, transportation influence degree storage unit 180, time zone candidate storage unit 190, and maintenance work plan candidate display unit 195. Information corresponding to the train operation information illustrated in FIG. 4 is stored in advance in the operation plan storage unit 150. Information corresponding to the transportation record information illustrated in FIG. 5 is stored in advance in the transportation record storage unit 160. The maintenance target storage unit 170 stores maintenance target information, which is information related to maintenance work that requires planning, which is input by the user of the maintenance work plan support device 10. FIG. 7 shows an example of maintenance target information. The maintenance target information of FIG. 7 associates a maintenance ID, which is an identification code of each maintenance work, with respect to a route, a section, a work content, a required time, and a deadline for carrying out the maintenance work input by the user of the maintenance work plan support device 10. I remember. In the example of FIG. 7, the maintenance work specified by A01 is the rail replacement work between the station A and the station B of the X-ray, and this work takes two hours and is by May 31, 2019. Indicates that this is work to be done. The implementation deadline can be used as a time constraint when the transportation impact calculation processing unit 120 reads out the train operation information. In the transport influence degree storage unit 180 and the time zone candidate storage unit 190, the transport influence degree and the time zone candidate calculated by the transport influence degree calculation processing unit 120 are recorded as shown in the example of FIG.

The maintenance work plan candidate display unit 195 has a function of displaying and outputting the maintenance time zone candidates extracted by the maintenance time zone candidate extraction processing unit 130. The mode of display output will be described later.

The transportation impact calculation processing unit 120 reads the maintenance target information from the maintenance target storage unit 170, and based on the read maintenance target information, either or both of the operation plan information and the transportation record information is stored in the operation plan storage unit 150, respectively. The transport impact degree is calculated by reading from the transport record storage unit 160, and the calculated transport impact degree is stored in the transport impact degree storage unit 180. Further, the maintenance time zone candidate extraction processing unit 130 reads the transport influence degree from the transport influence degree storage unit 180, and stores the maintenance work time zone candidate extracted based on the transport influence degree in the time zone candidate storage unit 190. The data processing by each processing unit included in the above maintenance work plan support device 10 will be described later.

Next, the hardware configuration of the maintenance work plan support device 10 will be described. FIG. 3 is a diagram showing a hardware configuration example of the maintenance work plan support device 10 in the present embodiment. The maintenance work plan support device 10 in the present embodiment is configured as a general computer having a communication function, and displays a processor 11 such as a CPU, a program executed by the processor 11, and data used by the program. A memory 12 composed of a storage device such as a ROM and a RAM for storing, an external storage device 13 such as a hard disk drive (HDD) and a semiconductor drive (SSD), and an input device such as a keyboard, a mouse, and a touch pad. An input device 14, an output device 15 which is an output device such as a monitor display and a printer, and a communication device 16 such as a network interface card (NIC) for communicating with other devices and terminals via a communication network N. A control device 17 for controlling data transmission / reception between the devices in the maintenance work plan support device 10 is provided. The function of the maintenance work planning support device 10 described with reference to FIG. 2 is realized by the processor 11 reading various programs stored in the external storage device 13 into the memory 12 and executing the functions. Other devices included in the railway comprehensive management system 1, the operation plan information management device 20, the transportation record information management device 30, the maintenance work information management device 40, and the work operation terminal 50 have almost the same configuration as the maintenance work plan support device 10. The functions of each device are realized by being configured as a computer having the above and executing the programs stored in each computer.

Data processing by the maintenance work plan support device 10 Next, data processing by the maintenance work plan support device 10 will be described with reference to a processing flow example. FIG. 10 is a diagram showing an example of an overall data processing flow of the maintenance work plan support device 10 in the present embodiment. The data processing flow illustrated in FIG. 10 is executed by the processor 11 of the maintenance work planning support device 10. First, using the data processing start command received from the business operation terminal 50 via the communication network N as a trigger, the maintenance work plan support device 10 executes the transportation impact calculation process S101 and the maintenance time zone candidate extraction process S102. End the process.

The transportation impact calculation process S101 is executed by the transport impact calculation processing unit 120 in the maintenance work plan support device 10, and the maintenance time zone candidate extraction process S102 is the maintenance time zone candidate extraction processing unit 130 in the maintenance work plan support device 10. Is executed by. Each of these processes will be described later.

Transport Impact Calculation Process The transport impact calculation process will be described with reference to FIG. This transport impact calculation process S101 is mainly executed by the transport impact calculation processing unit 120 among the data processing operations of the maintenance work plan support device 10 in the present embodiment, and the operation plan information and the transport are performed based on the maintenance target information. An example of data processing flow when calculating the degree of transportation impact is shown by referring to either or both of the actual information.

First, the control processing unit 140 of the maintenance work plan support device 10 that receives the operation instruction from the business operation terminal 50 via the communication network N reads the maintenance target information from the maintenance target storage unit 170, and the transportation impact calculation processing unit. Instruct 120 (S201).

The transport impact calculation processing unit 120 reads the maintenance target information from the maintenance target storage unit 170 (S202). Specifically, the transportation impact calculation processing unit 120 includes information for identifying the target included in the maintenance target information reading instruction, for example, the maintenance ID, the target route, and the section illustrated in the maintenance target information of FIG. Maintenance target information can be read using items such as work content, required time, or implementation deadline as keys. Of course, all the maintenance target information stored in the maintenance target storage unit 170 may be read at the time of reading.

Next, the transportation impact calculation processing unit 120 sets the operation plan information stored in the operation plan storage unit 150 and the operation plan information stored in the operation plan storage unit 150 based on the maintenance target route, section, and maintenance work time required included in the read maintenance target information. Read either or both of the transportation record information stored in the transportation record storage unit 160 (S203). Specifically, assuming that the line and section to be maintained correspond to the section from station A to station B on the X line and the time required for the maintenance work is T time, the transportation impact calculation processing unit 120 Scans the operation schedule of the section from station A to station B on the X line stored in the operation plan storage unit 150 from the first train to the last train with a time width of the required time T (or time αT obtained by multiplying T by a predetermined coefficient α). To do. Then, the transportation impact calculation processing unit 120 reads, for example, N time zones from the time zone in which the number of trains operated during the time width T is the smallest. Further, the transportation impact calculation processing unit 120 reads out the transportation record information in the N selected time zones from the transportation record storage unit. Here, the transportation record information read out is data of all users who use the train operated between the station A and the station B in the corresponding time zone.

More specifically, the transportation impact calculation processing unit 120 sets a maintenance work time zone candidate from a certain time t to T time in the daytime train operation time zone, and sets the station A from time t to time t + T. Acquire the number of trains that depart and head for station B as the number of affected trains. On the other hand, the transportation impact calculation processing unit 120 departs from the station A from the time t to the time t + T from the record of the entry / exit station and the entry / exit time for all the ticket IDs recorded in the transportation record storage unit 160. The number of passengers is counted for each train. At this time, from the entry / exit station and entry / exit time records for each ticket ID, the user holding the ticket can take the train according to a reasonable boarding route or the waypoint setting set for the ticket. If station A to station B are included in the route, it is considered that after arriving at station A along the boarding route, the train departing from station A is boarded next. By the above method, the number of trains affected during the required work time and the number of passengers on each train can be calculated.

The coefficient α is used for the purpose of including a predetermined margin in the required time in order to prevent a situation in which the actual work takes a longer time than the specified required time and the influence on transportation becomes large. can do. Further, the particle size when scanning from the first train to the last train in the time width of the required time T may be set in advance as, for example, 10 minutes.

The transportation impact calculation processing unit 120 calculates the actual number of people transported between stations A and B for each of the N cases in the time zone from the read transportation record information, and stores the transportation impact memory unit 180 as the transportation impact. Remember (S204).

In addition to the above-mentioned actual number of people transported, the following indicators can be used as the degree of transportation impact.

-Time axis fluctuation of the actual number of people transported If the actual number of people transported fluctuates significantly from day to day for a certain time zone, it is convenient for a larger number of users to perform maintenance work during that time zone. It is thought that there is a high risk of damaging the number of users (risk of upside the number of users). In order to avoid such inconvenience, it is possible to preferentially select a time zone in which the time axis fluctuation amount of the actual number of people transported is equal to or less than a certain amount. As the time axis fluctuation amount of the actual number of people transported, the variance, standard deviation, etc. of the actual number of people transported can be adopted.

・ Percentage of users who use the section between station A and station B more than a certain frequency For a certain time period, the ratio of users who use the target section more than a certain frequency (once every two days, etc.) with respect to the actual number of people transported If it exists in a certain proportion or more, it is not preferable to carry out the maintenance work during the time period because it impairs the convenience of the regular users. In order to avoid such inconvenience, it is possible to lower the selection order in the time zone in which the above-mentioned permanent users exist at a certain ratio or more.

・ Percentage of users whose time fluctuations are below a certain level when using between Station A and Station B It is assumed that the users who use the target section are constantly using the same train or similar trains during a certain time zone. For example, it is considered that the same time zone is a time zone where there are many regular users such as commuting to school. Performing maintenance work during such hours is not preferable because it impairs the convenience of regular users such as commuting to work or school. In order to avoid such inconvenience, it is conceivable to lower the selection order of the time zone in which it is considered that there are many regular users as described above.

For a plurality of maintenance work time zones set based on the maintenance target information by the data processing of the transportation impact calculation processing unit 120 explained above, from the operation plan information and the transportation record information, the maintenance work is carried out to the user. It is possible to calculate the degree of transportation impact, which is an index showing the impact.

FIG. 8 shows an example of the configuration of the transportation impact storage unit 180 that stores the maintenance ID, which is a code for specifying the maintenance target in the maintenance target information, in association with the calculated transportation impact and the corresponding time zone. ..

Maintenance time zone candidate extraction process Next, the maintenance time zone candidate extraction process will be described. FIG. 12 shows data processing by the maintenance time zone candidate extraction processing unit 130 when extracting maintenance work time zone candidates based on the calculated transport influence degree in the processing operation of the maintenance work plan support device 10 in the present embodiment. A flow example is shown.

First, the control processing unit 140 of the maintenance work plan support device 10 that receives the transportation impact reading instruction from the business operation terminal 5 via the communication network N sends the maintenance time zone candidate extraction processing unit 130 to the transportation impact storage unit 180. Instructs the reading of the transport impact degree (S301).

The maintenance time zone candidate extraction processing unit 130 reads the transport influence degree from the transport influence degree storage unit 180 in response to the read instruction (S302).

Next, the maintenance time zone candidate extraction processing unit 130 extracts the maintenance work time zone candidate based on the read transport influence degree (S303). Specifically, for example, when the actual value of the number of people transported is used as the standard, it is judged that the smaller the value, the smaller the impact on transportation even if the time zone is devoted to maintenance work, and the actual value of the number of people transported is smaller. Priority is given to extracting maintenance work time zones from the time zones.

In addition, it is also possible to evaluate the impact on transportation by adding other indicators.

-As for the amount of time-axis fluctuation of the actual number of people transported, the smaller the value, the lower the risk that the impact on transportation will increase due to the increase in the number of people transported, so this value (for example, dispersion of actual number of people transported, standard deviation, etc.) It is possible to think that the smaller time zone is preferentially extracted as a candidate for the maintenance work time zone.

-As for the percentage of users who use the target section more than a certain frequency, the smaller the value, the smaller the impact on so-called heavy users, so this value is also a candidate for the maintenance work time zone preferentially from the smaller time zone. You can think of extracting as.

-The idea is that the percentage of users whose time fluctuation is below a certain level when using the target section (usually used in the same time zone) is also preferentially extracted as a candidate for maintenance work time zone from the smaller time zone. Can be done.

With reference to the example of FIG. 8, for the maintenance work specified by the maintenance ID of A01, the degree of transportation influence is recorded by the actual number of people transported. In this case, "14:00 to 16:00 on May 25, 2019" is first extracted in ascending order of transport impact, and then "10:00 to 12:00 on May 25, 2019". Will be extracted. Regarding the other indicators mentioned above, it is conceivable to extract maintenance work time zone candidates based on any of these indicators, but in terms of evaluating the impact on transportation, first, the actual number of people transported is used as the basis. It may be preferable to determine the ranking and adjust the ranking to take into account other indicators to reduce the impact.

Next, the maintenance time zone candidate extraction processing unit 130 stores the extracted maintenance work time zone candidates in the time zone candidate storage unit 190 (S304). When the priority information based on the other index is given in S303, the priority information is also stored. FIG. 9 shows an example of the configuration of the time zone candidate storage unit 190. In the example of FIG. 9, for one maintenance target information, the time zone candidates are first arranged in ascending order of the actual number of people transported, and the ranking when evaluated by other indexes is shown in association with each time zone candidate. ing. For example, in the example of FIG. 9, it is shown that when the ratio of passengers who use the section between station A and station B at a constant frequency is evaluated, the ranking is different from the ranking based on the actual number of people transported. In this case, the person in charge of maintenance work planning can determine the final time zone candidate in consideration of the ranking of the ratio of regular users.

Finally, the control processing unit 140 of the maintenance work plan support device 10 displays the time zone candidate data stored in the time zone candidate storage unit 190 on the monitor display as the output device 15, or via the communication network N. A series of data processing is completed by transmitting the data to the business operation terminal 50 (S305). An example of the output screen will be described later.

As described above, according to the present embodiment, when the train operation is stopped in the daytime and the maintenance work of the railroad track or the like is performed, the transportation influence degree such as the actual number of people transported in the section where the operation is stopped is used. , Maintenance work time zone candidates can be extracted, and maintenance work that can further reduce the impact on transportation becomes possible. In addition to the actual number of people transported, other factors such as the amount of time-axis fluctuations in the actual number of people transported in the maintenance target section, the ratio of passengers with a certain frequency or more, the ratio of passengers with little fluctuation in usage time, etc. If maintenance work time zone candidates are extracted in consideration of the evaluation index, the influence on transportation can be further reduced.

In addition, in extracting maintenance work time zone candidates, it is also possible to adopt a simple method of ranking according to the number of affected trains, which is required from the operation plan information, without using the above-mentioned transportation record information. ..

Other Embodiments Next, other embodiments of the present invention will be described. FIG. 13 shows an example of the functional configuration of the maintenance work plan support device 10 in another embodiment. The maintenance work plan support device 10 illustrated in FIG. 13 is different from the previous embodiment in that it includes a maintenance cost storage unit 197. Compared to the conventional case where maintenance work is performed during the midnight hours when there is no train operation, if the same maintenance work is performed during the daytime operation hours, maintenance costs such as labor costs for workers are advantageous. It is possible that Therefore, when presenting the maintenance work time zone candidate to the person in charge of planning the maintenance plan, it is considered that presenting the maintenance cost information together is useful for making a decision in planning the maintenance plan.

FIG. 6 shows a configuration example of the maintenance cost storage unit 197. The maintenance cost storage unit 197 illustrated in FIG. 6 provides maintenance cost information that is the same data as the above-mentioned maintenance construction information, such as the work content of the maintenance work, the work unit for cost calculation, and the daytime for the corresponding work unit. And each item of the cost of midnight is associated and memorized. In the example of FIG. 6, the daytime and midnight costs when the rail exchange is carried out over 100 m are recorded as MMM yen and mmm yen, respectively. By multiplying this so-called maintenance work cost unit price by the work execution extension distance (which can be obtained from the operation information, which is a train schedule) according to the work content in the maintenance work information, the maintenance work can be performed in the daytime. And you can get the cost of each if you do it at midnight.

FIG. 14 shows an example of a data processing flow of the maintenance time zone candidate extraction process S102 in the present embodiment including maintenance cost information. The data processing flow example of FIG. 14 is different in that the processing step of S3041 is added to the data processing flow example of FIG. In S3041, the maintenance time zone candidate extraction processing unit 130 reads the maintenance cost information applied by using the work content as a key for the maintenance target information used for extracting the maintenance time zone candidate from the maintenance cost storage unit 197, and maintains the maintenance target information. Calculate the maintenance cost when maintenance work is performed in the daytime and midnight on the routes and sections included in. In S305, the calculated daytime and midnight maintenance costs are also displayed together with the extracted maintenance time zone candidates. This makes it possible to compare candidates for maintenance work time zones while looking at the degree of transportation impact and maintenance cost side by side for maintenance work that is the target of maintenance planning, making maintenance work planning more effective. It will be possible to provide support.

FIG. 15 shows an example of an interface screen of the business operation terminal 50 when performing maintenance planning work according to the present embodiment. In the upper half of the interface screen of FIG. 15, a train schedule including routes and sections for which maintenance work is to be performed is displayed. In the lower half of the interface screen of FIG. 15, the work contents of the maintenance work related to the planning, the target route, the input field of the section, the extracted time zone candidate, and the calculated maintenance cost are arranged. The person in charge of maintenance planning inputs the desired target in the work content and route / section fields, and operates the trial calculation execution button to extract the maintenance time zone candidates and the daytime and midnight maintenance in the time zone. The cost is calculated and displayed (in the example of FIG. 15, the maintenance cost is shown as an index when the midnight implementation is 100). In addition, the time zone corresponding to the maintenance time zone candidate extracted as the most suitable candidate may be graphically displayed on the train schedule (example: rectangular shaded portion surrounded by a broken line in the figure). The interface screen example of FIG. 15 is merely an example, and the configuration of the display mode, displayed items, arrangement, and the like can be appropriately changed.
