CAN bus message maintenance monitoring system and monitoring method of railway vehicle brake system

Abstract

The invention relates to a CAN bus message maintenance monitoring system and monitoring method of a railway vehicle brake system. The monitoring system comprises a vehicle-mounted maintenance terminal, a configuration management software module, and a data analysis software module, wherein the vehicle-mounted maintenance terminal is connected with a CAN bus of the brake system and is used for collecting, forwarding and storing message data; the configuration management software module is connected with the vehicle-mounted maintenance terminal and is used for parameter configuration, data downloading and data real-time monitoring; and the data analysis software module is connected with the vehicle-mounted maintenance terminal and is used for unpacking the message data directly forwarded bythe vehicle-mounted maintenance terminal, performing image processing, then displaying in real time in the form of an indicator lamp, an instrument panel, a data list and a dynamic curve, sending an instruction to the vehicle-mounted maintenance terminal, and playing back the message data stored by an SD memory card module in the vehicle-mounted maintenance terminal and the data recorded by the data analysis software module. According to the system and the method in the invention, data acquisition, configuration, storage and analysis are integrated, the function is complete, the practicabilityis high, and the braking performance and the safety of railway vehicles are improved.

Description

technical field [0001] The invention belongs to the technical field of rail vehicle control, and relates to a rail vehicle braking system monitoring technology, in particular to a rail vehicle braking system CAN bus message maintenance monitoring system and a monitoring method. Background technique [0002] The CAN bus message maintenance monitoring system is an important part of the braking system and plays an important role in ensuring the safety and reliability of train operation. It is a bridge for information interaction between the brake control unit and the PC host computer, receiving the status information, control information and fault information sent by the vehicle brake control device, and sending these data information to the host computer (for example: laptop) on site to In the form of indicator lights, data lists and dynamic curves, monitor the running conditions of the train. [0003] In recent years, with the rapid development of the rail transit industry, ...
