Health management system of braking and air supply system for motor train unit

Abstract

The invention provides a health management system of a braking and air supply system for a motor train unit, and relates to the field of braking of a rail transit system. The health management systemaims to solve the problems that a health management system of an air supply system is long in data updating period, original data cannot be stored and accumulated, and therefore, early warning of faults cannot be achieved in advance and preventive maintenance suggestions cannot be provided before the faults occur. A braking system control unit and a train-mounted health management host are in datainteraction through the Ethernet, and the train-mounted health management host forms intelligent driving information according to an early warning result of an early warning module and feeds back theintelligent driving information to a train-mounted PAD end; the train-mounted health management host and a health management ground data center achieve real-time transmission of train in-transit states and fault information through the Internet, and after a train returns to a motor train unit maintenance depot, all original data of the train on the current running day are sent to the health management ground data center through a high-speed wireless network relay interface in the depot and used for data deep analysis and screening. According to the system, manpower, logistics and storage costs are reduced.

Description

technical field [0001] The invention relates to the field of braking in rail transit systems, in particular to a health management system for braking and air supply systems for train sets. Background technique [0002] At present, the remote data management system is generally installed in the EMUs in operation. The system sends the fault codes and main driving parameters during the operation of the vehicles to the ground data center through the on-board data transmission device to monitor the status of the EMUs, 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 does not have data processing capabilities and cannot carry early warning and prediction models. When it is applied to the health management of the brake and air supply system, there are problems such as long data update cycle, original data can...

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
