Example Embodiment

[0061] In order to make the objectives, technical solutions, and advantages of the present invention clearer, the following further describes the embodiments of the present invention in detail with reference to the accompanying drawings.

[0062] figure 1 A flowchart of a method for diagnosing real-time train faults according to an embodiment of the present invention is shown.

[0063] In order to perform real-time fault diagnosis on the train, in step S101, during the traction process of the traction force formation process performed by the train, the status information of each traction process step is identified through the status recognition module. First, the train sends out a traction command to execute the traction process, and then the train starts to execute the various steps of the traction process. When executing each step, the status recognition module on the train will recognize the status information of each traction process step and determine whether the step is execu...

Abstract

The invention provides a method for diagnosing real-time faults of a train, which comprises the following steps of: identifying state information of each traction process step through a state identification module during a traction process period of executing a traction force forming process by a train; receiving the state information through a service platform, and screening out a traction process step with a fault according to the state information and the traction process logic; and analyzing the fault tree corresponding to the traction process step with the fault, and obtaining a fault diagnosis result according to the fault logic of the fault tree. According to the method and system for diagnosing the real-time faults of a train, the real-time faults of a train can be checked under the traction process working condition, various faults related to train traction are involved, ground personnel can rapidly locate the faults, and a driver can conveniently conduct further operation. The processing time of train faults is shortened, and the influence of the faults on the train is reduced.

Description

technical field [0001] The invention relates to the field of train control, in particular to a method and system for diagnosing train real-time faults. Background technique [0002] At present, the mileage of trains in our country continues to expand, and the number of trains required also increases sharply. Therefore, the safety of trains is the top priority in the work of railway departments. my country's train industry fault diagnosis technology is mainly limited to the diagnosis of some key equipment, components and parts. It rarely involves the comprehensive diagnosis of the whole train system under different working conditions, and the current fault diagnosis method is not efficient, which is not conducive to the investigation of key fault causes and effective guidance to drivers. [0003] Therefore, in order to better troubleshoot train faults, there is an urgent need for a method and system for diagnosing train faults in real time. Contents of the invention [00...
