Embodiment 1

[0059] Embodiment 1: as attached figure 2 And attached image 3 As shown, a specific embodiment of a fault diagnosis system for a rail grinding vehicle includes: a vehicle-mounted device 10 and a ground server 2 , and the vehicle-mounted device 10 is arranged on the rail grinding vehicle 1 . The rail grinding vehicle 1 also includes a switch 11, a network system, a grinding control host 12 and a travel control host 13, and the vehicle-mounted device 10, the switch 11, the grinding control host 12 and the travel control host 13 are connected through a network system, and the ground server 2 includes Vehicle-ground communication server 21, fault diagnosis server 22 and database server 23. The vehicle-mounted device 10 obtains the monitoring and / or diagnosis information of the grinding control host 12 and the running control host 13 through the switch 11, and performs fault analysis to obtain fault phenomenon and fault type information, including fault phenomenon, fault type in...

Embodiment 2

[0063] Embodiment 2: as attached image 3 As shown, on the basis of Embodiment 1, the ground server 2 also includes a database server 23, and the database server 23 adopts the Oracle database system to store various data, and the data is mainly divided into three categories:

[0064] (1) Management data, including vehicle information, user information, unit information, etc.;

[0065] (2) Historical data, including vehicle failure records, vehicle maintenance records, etc. Users can query, analyze and make statistics on fault information through historical data, understand the occurrence rate of various faults, fault distribution and other information, as a reference for vehicle repair and maintenance;

[0066] (3) Diagnosis expert database, including various causes of failures, various failure phenomena, and various failure solutions, etc., is a support library for fault diagnosis.

[0067] The database server 23 further includes a user information database 230 , a vehicle ...

Embodiment 3

[0075] Embodiment 3: If the rail grinding car 1 has multiple different models, then in order to realize the fault diagnosis of the rail grinding car 1, it is first necessary to analyze the Ethernet communication protocols of various types of rail grinding cars 1, and determine the Ethernet communication protocol in the Ethernet data packet. The corresponding relationship between the data and each parameter, so as to extract the required monitoring and diagnosis data. Secondly, analyze the definition of the fault information of the rail grinding car 1, and judge the type and information of the fault occurring at this time according to the extracted diagnostic data. as attached Figure 4 And attached Figure 5 As shown, on the basis of the foregoing embodiments, the vehicle-mounted device 10 is connected to the Ethernet of the rail grinding vehicle 1 through the switch 11, listens to the data sent by the grinding control host 12 and the running control host 13 to the network, a...

Abstract

The invention discloses a fault diagnosis system for a rail grinding wagon. A vehicle-mounted device obtains monitoring and / or diagnosis information of a grinding control host computer and a walking control host computer through an interchanger and analyzes the fault to obtain the information of the fault phenomenon and the fault type. When the vehicle-mounted device judges that the rail grinding wagon breaks down, the fault type is sent to a fault diagnosis server, the fault type information is automatically pushed to a client, and a user is reminded to carry out the corresponding fault diagnosis. When the user selects to carry out the fault diagnosis on the rail grinding wagon, the fault diagnosis server sends an order to the vehicle-mounted device and receives data which are returned by the vehicle-mounted device and include the fault phenomenon of the rail grinding wagon, and the fault diagnosis server obtains the corresponding fault reason and the solution according to the fault phenomenon information and sends the corresponding fault reason and the solution to the client. The fault diagnosis system solves the technical problems that in the prior art, the operating state of the rail grinding wagon cannot be remotely monitored in real-time, efficiency is low, and a decision basis cannot be provided for maintaining the rail grinding wagon.

Description

technical field [0001] The invention relates to electrical equipment of railway engineering machinery, in particular to a fault diagnosis system for rail grinding vehicles applied in the field of railway engineering vehicles. Background technique [0002] At present, my country's rail grinding vehicle control systems all rely on imports, the system is complex, and there are many types. In addition, there are not many users of rail grinding vehicles in the early stage. During the use process, there are problems that are difficult to troubleshoot. On-site faults are completely dependent on manual troubleshooting. , there is a time-consuming shortcoming, which seriously affects the effective working time of the rail grinding car. At the same time, since the control system of the imported rail grinding vehicle itself has a fault diagnosis function, its fault diagnosis algorithm is complex and not public, and in order not to affect the normal operation of the rail grinding vehicle...
