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.
