Description

Technical Field

[0001] The present application relates to the technical field of railway engineering machinery, and in particular to an active diagnosis method for a tamping vehicle of a tamping vehicle. Background Art

[0002] As the total mileage of my country's railways continues to grow, the workload of railway maintenance is increasing. Tamping vehicles are essential operating vehicles for railway maintenance work. They perform leveling, track lifting and tamping operations on the line, increase the density of the ballast of the roadbed, eliminate deviations in the direction, level, longitudinal and other parameters of the line, improve the stability of the line, and ensure the safe and high-speed operation of trains. Tamping vehicles need to operate in the blockade section. The general operation blockade time is 3 hours. The workload is large, the time saturation is high, and the tamping operation environment is harsh. The vehicle system, especially the electrical system, has a high failure rate. Once a fault occurs and cannot be promptly investigated and resolved, it will affect the workload of the tamping vehicle, and in serious cases, it will even affect the opening of the line.

[0003] In the prior art, the following documents are mainly related to this application:

[0004] Prior art 1 is a Chinese invention application filed by Zhuzhou Times Electronic Technology Co., Ltd. on July 13, 2017 and published on September 12, 2017, with publication number CN 107153394A. The application discloses a tamping vehicle operation protection control system, including: a lower main board and a program-controlled main board, the lower main board collects analog quantities of track lifting and track shifting operations, and converts the analog quantities into digital quantities. The lower main board calculates the total track lifting amount according to the digital quantity of the track lifting operation, calculates the total track shifting amount according to the digital quantity of the track shifting operation, and judges whether the operation blocking condition is met according to the total track lifting amount and the total track shifting amount, and sends the judgment result to the program-controlled main board. When the program-controlled main board receives the operation blocking signal, the program-controlled logic signal of the corresponding operation action is eliminated, and the electrical signal of the corresponding operation control valve is cut off. The invention can solve the technical problem that the existing tamping vehicle cannot perform self-protection during operation, and the operation mechanism will not stop when an emergency occurs, causing serious accidents such as over-lifting and over-shifting, and even damaging the line and smashing the rails.

[0005] However, the existing technology has technical defects such as complex control logic of tamping vehicles, inability of operators to quickly locate and handle problems, lack of analytical methods for complex non-logical faults, long-term arrangement of professional personnel to follow the vehicle for handling, long cycle, low efficiency, etc. During the operation of the tamping vehicle, the electrical system has a high failure rate and the operation blockade time is short. If the failure is not handled in time, it will affect the opening of the line. Summary of the invention

[0102] For the purpose of reference and clarity, the technical terms, abbreviations or abbreviations used below are recorded as follows:

[0103] CAN: Short for Controller Area Network;

[0104] MCM: short for Main Control Module;

[0105] C / S: Abbreviation for Client / Server, which is the client / server architecture mode. In this architecture, the server is responsible for managing the database, processing data requests, and providing services such as business logic processing, while the client is responsible for interacting with the user, sending user requests to the server, and displaying the results returned by the server.

[0106] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0107] As attached Figure 1 To Attachment Fig.25 As shown, a specific embodiment of the active diagnosis method for the tamping vehicle of the present application is given, and the present application is further explained below in conjunction with the drawings and specific embodiments.

[0108] The active diagnosis method for tamping vehicles in this application adopts the on-site CAN bus as a digital communication carrier, and connects the entire control system through the network from beginning to end to form a complete control network. The CAN bus control method has the characteristics of networking, digitization, and modularization. Its on-board network control system is not only adapted to the development of advanced network technology, but also has a short product development cycle and high reliability. It can enhance the intelligence level of rail engineering machinery and improve the efficiency of on-site fault handling.

[0109] Example 1

[0110] As attached Figure 1 As shown, an embodiment of the active diagnostic device for a tamping vehicle based on the method of the present application specifically includes:

[0111] The main control module (MCM module) runs the on-board intelligent diagnosis and operation and maintenance server software, which is a C / S embedded server program. It runs the core service functions, collects and records bus data and saves it as files, and realizes functions including active diagnosis, logic diagnosis, expert diagnosis, operation data record analysis, and operation data record analysis. At the same time, it is installed with an on-board database to manage data operation and maintenance information including basic vehicle information, equipment information, maintenance information, fault records, and operation records.

[0112] The wireless routing module (vehicle-mounted wireless AP) is connected to the main control module to achieve network access to vehicle-mounted devices through vehicle-mounted wireless networking;

[0113] An intelligent diagnostic display, connected to the wireless routing module, is used to realize intelligent diagnosis of vehicle network control system faults and intelligent monitoring of the life cycle of each module in the vehicle network control system;

[0114] The vehicle-mounted mobile communication module is connected to the wireless routing module. When the vehicle-mounted public network opens access rights, the main control module and the intelligent diagnosis display establish a connection with the remote diagnosis system through the wireless routing module to achieve real-time remote monitoring diagnosis and data synchronization on the vehicle. The vehicle-mounted mobile communication module can specifically adopt a vehicle-mounted 4G / 5G module.

[0115] The active diagnosis method for the tamping vehicle also includes a vehicle-mounted mobile display (which can be a vehicle-mounted tablet) connected to the wireless routing module, and the client interactive software is run in the vehicle-mounted mobile display, and the main control module is accessed through the wireless local area network to achieve human-machine interface access. When there is no access permission to the vehicle public network, the offline collected data files can be uploaded to the remote diagnosis system.

[0116] When the diagnosis process starts, the main control module obtains data related to the diagnosis of the vehicle network control system from the Ethernet or bus. After the data verification is passed, it determines the abnormal trend of each data change, analyzes the cause of the fault according to the fault tree, and gives fault handling measures. If the cause of the fault cannot be determined, the fault probability is given, the diagnosis results are recorded and fed back to the intelligent diagnostic display.
