A health management system for braking and air supply systems for EMUs

Abstract

A health management system for brakes and air supply systems for EMUs, which relates to the field of rail transit system brakes. In order to solve the problems of the health management system of the air supply system, the data update cycle is long, and the original data cannot be stored and accumulated. It is impossible to give early warning of faults and put forward preventive maintenance suggestions and other issues. The brake system control unit and the vehicle health management host realize data interaction through Ethernet. The vehicle health management host forms intelligent driving information according to the early warning results of the early warning module and feeds back to the vehicle PAD terminal. ;The on-board health management host and the health management ground data center realize the real-time transmission of vehicle status and fault information through the Internet. The data is sent to the health management ground data center for in-depth data analysis and screening. The system of the present invention reduces manpower, logistics and storage costs.

Description

technical field [0001] The invention relates to the field of rail transit system braking, in particular to a health management system for a braking and air supply system for an EMU. Background technique [0002] At present, a remote data management system is generally installed in the operating EMUs. The system sends the fault codes and main driving parameters that occur during the operation of the vehicle to the ground data center through the on-board data transmission device to monitor the status of the train group, including braking and Air supply system data. The structure of the remote data management system is simple. Due to the limitation of its own communication capacity, it can only transmit some faults and system parameters. It cannot carry early warning and prediction models without data processing capabilities. When it is applied to the health management of braking and air supply systems, there are problems such as long data update cycle, unable to form accumula...

AI Technical Summary

Problems solved by technology

[0004] In order to solve the problems that the health management system of the air supply system has a long data update cycle, and the original data cannot be stored and accumulated, so that it is impossible to warn the fault in advance and propose preventive maintenance suggestions before the fault occurs, the invention provides a brake for the EMU. And the health management system of the air supply system to meet the needs of the whole life cycle management and intelligent maintenance of EMUs
