Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a maintenance management system for a railway vehicle including a monorail.

[0002]

2. Description of the Related Art Strict statutory inspection work is required for those who operate and manage railway vehicles in order to ensure safety of railway vehicles and public equipment on public transportation.

[0003] Maintenance of railcar-mounted equipment may be replaced periodically in accordance with the statutory inspection work described above, or may be repaired or replaced when there is an abnormality or failure.
However, if maintenance is performed after an abnormality or failure occurs, the operation of the railway vehicle is hindered, which is not appropriate. In addition, when all the mounted devices are regularly replaced in the legal inspection work, the devices are replaced with usable ones, resulting in waste and an increase in cost.

As means for solving this problem, Japanese Patent Application Laid-Open No. Hei 8-2
Japanese Patent Application Publication No. 51702 discloses a management device for equipment mounted on a railway vehicle, which records the operation history of the mounted equipment for maintenance. The equipment information transmission means, the monitor unit, the ground transmission means, the ground equipment, and the like. A device identification number is assigned to a target of maintenance of the mounted device, a recording unit of a maintenance management characteristic value is provided, and the device information transmitting unit mediates information between the monitor unit and the mounted device. The monitor unit receives information from the device information transmission unit, and organizes and records information on the on-board equipment to be managed. The ground transmission unit transmits the information arranged and recorded in the monitor unit to the ground equipment. The above-mentioned ground equipment records and monitors the history of the on-board equipment to be managed, and a management apparatus for on-board equipment on a railway vehicle that issues maintenance information in accordance with a maintenance standard is disclosed.

[0005]

The above-mentioned JP-A-8-251
Conventionally, a railway company that manages railway vehicles, including those described in Japanese Patent Application Publication No. 702, constantly monitors the on-board equipment of its own vehicle in detail, and determines when to replace parts according to maintenance standards. Similarly, each monorail operating company had its own maintenance management for the monorail.

[0006] Incidentally, a small-scale local railroad or monorail operating company has a small number of trains to operate, and therefore, when performing maintenance of a railcar, it also requires human resources (parts, facilities, equipment, etc.).
It is thought that economies of scale will not come out to the testing machine). That is, the following is expected. (1) Usually, details of the monitored maintenance management characteristic values are not disclosed to anyone other than the railway vehicle operating company. It is considered that these maintenance management characteristic values include a lot of information that is effective for improving products and parts that are hard to break down and easy to maintain. However, since individual vehicle manufacturers and component manufacturers themselves do not perform maintenance directly, not all maintenance information on products and parts is fed back, and the reflection of maintenance information on product development is not always sufficient. . (2) Since each operating company separately orders and purchases parts from each parts manufacturer, the market size is small, and the number of parts to be produced by each parts manufacturer is small. On the other hand, high reliability is required for each component to ensure safety. Therefore, it is difficult to reduce the price of parts. (3) Since each railway vehicle operating company has its own maintenance system and performs maintenance individually, the maintenance know-how is individual to each company. For small-scale railway operators, there are few opportunities to accumulate maintenance know-how because the number of trains operated is small, and it is difficult to improve maintenance know-how. On the other hand, people with advanced maintenance expertise,
The economic burden on the operating company associated with collecting high-performance diagnostic equipment increases.

An object of the present invention is to provide a maintenance management system capable of providing a scale advantage for maintenance of a railway vehicle of a small-scale local railway or a monorail operating company.

Another object of the present invention relates to the maintenance of rail cars of a small local rail or monorail operator.

I do.

Next, the operation of the system shown in FIG. 1 will be described. First, in the maintenance schedule table for each railway company in the maintenance schedule database 140, the timing of the maintenance inspection and additional items of the maintenance inspection are recorded. That is, FIG.
As shown in (1), statutory inspection items for each railway company are recorded and updated in the database of maintenance inspection items, and preventive maintenance items for each railway company are recorded and updated in the preventive maintenance schedule database (S1100). ~ 1110).

The following items are legally inspected for monorail vehicles.

(A) Inspection of trains (b) Monthly inspection (c) Inspection of important parts (d) General inspection (e) Inspection of newly manufactured vehicles (f) Inspection of vehicles suspended from use (g) Notation of inspection Records In addition, there are also maintenance and inspection items for electricity, civil engineering, and station buildings.

As preventive maintenance items, there is also a preventive maintenance operation that is carried out independently of legal rules. For example, tires, brake linings, pantograph slides, etc.
It is replaced regularly and the maintenance date is recorded. The cooler also needs regular inspection and maintenance. Regarding the replacement time of the tire, it is desirable to monitor the change in the outer diameter of the tire by the sensor 830 and determine the replacement time based on the actual tire condition such as abnormal wear.

The legal inspection items and preventive maintenance items are combined with the deadline, and a legal inspection schedule database shown in FIG. 3 and a preventive maintenance schedule database shown in FIG. 4 are created.

Further, as shown in FIG. 5, an abnormality countermeasure database in which correspondence items at the time of occurrence of abnormality are recorded is also created.
This records specific items such as malfunction of tire puncture detection and overcurrent, and a reconfirmation deadline. This data creation also refers to the records in the maintenance record database that was treated at times other than during the periodic inspection.

The contents of the statutory inspection schedule database, the preventive maintenance schedule database, and the abnormality countermeasure database are subjected to predetermined processing, uploaded to the network connection device 130 (server) of the maintenance management company 100, and transmitted to each railway company. , Manufacturing companies and maintenance companies can access the site via the Internet and browse only the parts related to the company.

As described above, the information acquired and generated by the maintenance management company is provided to each railway company and the related manufacturing company or maintenance company via the communication network, so that the maintenance information is reflected in product development. be able to. Further, utilization of such information is useful for diagnosing equipment and improving the quality of vehicle maintenance technology.

Next, the operation of the maintenance management system 110 will be described. FIG. 6 is a flowchart showing the operation of the maintenance management system 110.

First, a maintenance schedule for each railway company is determined. In the maintenance schedule tables for each company shown in FIG. 3 and FIG. 4, the timing of maintenance and inspection and additional items of maintenance and inspection are recorded as a database.

By extracting and using necessary items from this database, a database of maintenance and inspection items for each company as shown in FIGS. 7 and 8 is generated (S1202-1).
206). If the maintenance of Company A is performed first,
Reads out the maintenance database of the company,
Grouping is performed according to the necessity of maintenance equipment (S120).
8). Then, a specific scheduling related to the maintenance of the company A is performed (S1210). In this case, the dispatch of the company A during the maintenance work is also adjusted (S1212).
Once the specific schedule for maintenance is decided,
The dispatch of the maintenance staff is scheduled (S121).
4, 1220), and arrange maintenance personnel (S122).
1). In order to secure economies of scale, especially human resources with advanced expertise, it is desirable that all maintenance staff belong to one maintenance company in principle. It may be used.

Further, the operation of the equipment necessary for the maintenance is scheduled (S1216, 1218), and the maintenance equipment is arranged (S1222). The maintenance equipment is collectively owned and managed by the maintenance management company 100 in order to secure the merit of the scale, and particularly to make use of high-performance equipment. The dispatch destination of the maintenance staff and the scheduling of the operation of the equipment are determined in consideration of not only the railway company A but also the maintenance status of other companies, the maintenance staff, and the status of the equipment.

FIG. 9 is an example of a maintenance staff dispatch schedule. The dispatch destination, period, and work items are specified for each maintenance staff. The maintenance staff dispatch schedule can also be viewed by maintenance companies. In addition, each railway company can browse the locations related to the company.

FIG. 10 shows an example of a maintenance equipment operation schedule. The dispatch destination, period, and work items are specified for each maintenance staff.

Returning to FIG. 6, a request for arranging parts necessary for maintenance is further performed, and parts procurement is scheduled (S1).
224, 1226), parts company (or vehicle manufacturer)
(S1228). If there is a maintenance staff stationed at company A, the operation is scheduled (S1230).

FIG. 11 is an example of a parts ordering schedule. Delivery date, delivery destination, quantity, etc. are specified. In the parts ordering schedule, a manufacturing company such as a parts company can browse the parts related to the company. As described above, since the maintenance and management of the railway vehicles of a plurality of railway operators is performed by one maintenance management company at a time, it is also applicable to the railway vehicles of small-scale local railway operation managers and monorail operating companies. Regardless, a highly reliable component can be provided while enjoying the merits of scale and reducing costs.

As described above, the maintenance work of company A is performed based on the set schedule (S123).
2). The maintenance work is completed after confirmation of the contents of the company A (S1234). When you're done,
The result is recorded as a maintenance result (S1236). This data is recorded in the maintenance record database 1270 (S1270).

As for Company B, various scheduling and maintenance work are performed in the same manner as Company A (S121).
40-1266).

The part order schedule shown in FIG. 11 is generated from the following viewpoint. That is, regarding the monorail, tires, bearings, brake linings, pantograph slides, and the like are frequently worn and highly important from the viewpoint of security due to heavy wear.
For these parts, not only the manufacturing time of the parts manufacturer but also, for example, the company A can actually work according to the schedule and secure an appropriate allowance period (lead time) so as not to hinder the operation of the vehicle of the company A. For this purpose, data such as a transportation period from the parts manufacturer to the company A, a delivery date, an installation period, and a replacement period are created.

As shown in FIG. 12, the replacement time of each part is determined in consideration of the line conditions of each company, for example, company A.
decide. Further, as shown in FIG. 13, the load factor for the vehicle, that is, “the number of passengers” or “the number of passengers” of Company A
The number is determined in consideration of data. That is, the replacement time of each part is determined in consideration of “track condition” × “load factor for vehicle”.

FIG. 14 shows the timing of replacement of the same part by the company A and the company B based on the data shown in FIGS.

When it is necessary to replace a certain part of the vehicle, the actual data of the part is monitored, and the lower limit of the normal distribution of the data is determined based on the replacement criterion set for each part. I do. The time obtained according to the replacement determination criterion is set so that the lead time is appropriate for the use limit of the component.

Further, in this example, even if certain parts of the vehicles of the companies A and B are simultaneously replaced with new parts, the parts of the company B are greatly consumed and the replacement time is earlier.
However, the lead time of the company A is longer than that of the company B because it takes a long time to transport to the site and dispatch personnel since it is located in a remote place.

The various schedulings (S
1224, 1226, S1228, etc.) are performed based on such various situations between the companies. By deciding and executing maintenance replacement times in this way, each railway company can minimize the period of suspension of rolling stock for maintenance and inspection, and receive reliable maintenance services. Becomes possible.

As described above, since the maintenance management of the railway vehicles of a plurality of railway operators is performed by one maintenance management company at a time,
With regard to the maintenance of railway vehicles of small-scale local railway operation managers and monorail operating companies, not only railway operators but also manufacturing companies and maintenance companies can be provided with a maintenance management system having economies of scale. Furthermore, regarding maintenance of railway vehicles, it is possible to improve the quality of diagnosis of equipment and maintenance technology of vehicles.

Next, FIG. 15 shows the maintenance management system 110.
As another process, an example of a horizontal development process in which defect information relating to maintenance of parts of company A is reflected in maintenance of parts of company B is shown. First, a defect is extracted from the maintenance result database or the abnormality countermeasure database (S1270,
1272, 1400), it is determined whether the defect is related to another company's vehicle or another vehicle of the same company. For example,
If the component that caused the failure is also used in vehicles of other companies, it is desirable to consider the necessity of countermeasures. next,
Consider the existence of permanent measures. If so, a permanent measure is arranged, the result is recorded in the maintenance record database, and the process is terminated (S1276, 1278, 1290). If not, provisional countermeasures are considered (S1280, 1286), provisional countermeasures are arranged, and the results are recorded in the maintenance record database (S1).
282, 1284), and study and arrange permanent measures.
The result is recorded in the maintenance result database, and the processing ends (S1).
288, 1278, 1290).

According to the present invention, the contents of the abnormality countermeasure database are also disclosed to a related company to a certain extent, so that the maintenance information on products and parts is appropriately fed back, and the maintenance information is sufficiently provided to product development. Can be reflected in

FIG. 16 shows an example of an irregular process, in other words, an abnormal process, as another process of the maintenance management system 110. When an abnormality occurs in the equipment and facilities of the railway company, a request for a corresponding action is generated in the maintenance management system of the maintenance management company, and data of the content of the abnormality is sent (S1300, 1302). In the maintenance management system, the records of the maintenance record database and the operation record database are extracted, and the cause of the accident is analyzed (S1304). When the cause is determined, a countermeasure is examined and the railway company is contacted (S1306 to 1312). The maintenance management system determines whether it is necessary to dispatch maintenance personnel and arrange parts when taking measures against abnormalities, and performs necessary measures (S1314 to 1324), and records the result in the abnormal measures result database (S1326, 1400). The railway company takes necessary measures based on this communication and arrangement (S133).
0).

If the cause of the accident cannot be determined by analyzing the cause of the accident, the missing data is examined, and negotiation for obtaining necessary data is conducted with the railway company (S1332 to 1336).
For example, it is conceivable that the cause is determined by driving the failed vehicle under other conditions. Then, it is determined whether the dispatch of maintenance personnel is necessary for investigating the cause (and countermeasures) (S1338). If necessary, the maintenance company is requested to dispatch personnel (S1340 to 1342). If necessary data is obtained from the railway company in this way (S134
4) The cause is again investigated (S1346), and necessary measures are taken (S1306 to 1312).

In this way, an abnormal accident outside the regular inspection can be dealt with promptly. In particular, regarding the maintenance of rail cars of small local rail and monorail operators,
It is possible to quickly provide a reliable maintenance service.

[0066]

As described above, according to the present invention, the maintenance management company collectively manages the railway vehicles of a plurality of railway companies connected via a communication network. With regard to the maintenance of railway vehicles, a maintenance management system having economies of scale can be provided not only for railway operators but also for manufacturing companies and maintenance companies.

Since the information acquired and generated by the maintenance management company is provided to each railway company and the related manufacturing company or maintenance company via the communication network, the maintenance information can be reflected in product development. it can. Furthermore, regarding the maintenance of railway vehicles by a small-scale local railway operation manager or a monorail operating company, it is possible to diagnose equipment and improve the quality of vehicle maintenance technology.

In addition, since the maintenance and management of the railway vehicles of a plurality of railway operators is performed by one maintenance management company at a time, the maintenance costs of the railway vehicles of the small local railway operation manager and the monorail operating company are reduced. And a highly reliable maintenance service can be provided.
