Embodiment 1

[0098] Embodiment 1: as attached figure 2 and 3 As shown, a specific embodiment of a rail grinding vehicle fault diagnosis method based on the above-mentioned rail grinding vehicle fault diagnosis system, the rail grinding vehicle fault diagnosis system 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 superior. The rail grinding car 1 further 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 the network system. Ground server 2 comprises car-ground communication server 21, fault diagnosis server 22, and this method comprises the following steps:

[0099] (A) The vehicle-mounted device 10 obtains the monitoring and / or diagnosis information of the grinding control host 12 and the travel control host 13 through the...

Embodiment 2

[0103] Embodiment 2: On the basis of the foregoing specific embodiments, step (D) further includes the following steps:

[0104] Store information including rail grinding vehicle failure phenomena, failure causes and failure solutions to form diagnostic expert data, and store information including vehicle failure records and vehicle maintenance records to form historical data;

[0105] The fault diagnosis server 22 automatically expands the diagnostic expert data according to the user's method of troubleshooting and solving the fault of the rail grinding vehicle 1, or the user expands the diagnostic expert data according to the actual situation.

[0106] as attached Image 6 , 7 As shown in and 8, in step (D), when the user chooses to perform fault diagnosis on the rail grinding vehicle 1, the fault diagnosis server 22 sends a diagnosis command to the on-board device 10 through the vehicle-ground communication server 21, and the on-board device 10 receives the diagnostic comm...

Embodiment 3

[0107] Embodiment 3: as attached Figure 4 and 5 As shown, on the basis of the foregoing specific embodiments, in step (A), the vehicle-mounted device 10 is connected to the Ethernet of the rail grinding vehicle 1 through the switch 11, and listens to the sending of the grinding control host 12 and the running control host 13 to The data in the network, from which the monitoring and diagnosis information of the rail grinding car 1 is collected and saved, and the fault analysis is carried out, so as to obtain the fault occurrence information and fault type. There are two ways to analyze the fault phenomenon of rail grinding car 1:

[0108] (a) Direct analysis method, that is, directly use the diagnosis result of the grinding control host 12 (according to the fault flag bit) to determine the occurrence of the fault, such as the underlying modules (AI module, AO1 module, DO module and DI module) are used to indicate a certain Faulty digital input signals, offline and error stat...

Abstract

The invention discloses a fault diagnosis method 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 method solves the technical problems that in the prior art, the operating state of the rail grinding wagon cannot be monitored in real-time and remote mode, 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 method for a rail grinding vehicle 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 vehicl...
