A railway freight car failure prediction and health management system

Abstract

The invention discloses a railway freight car failure prediction and health management system, which includes a vehicle-mounted PHM system and a ground PHM system. The vehicle-mounted PHM system monitors the status of key systems and parts of railway freight vehicles in real time to obtain key position monitoring data and transmit To the ground PHM system, the big data processing platform in the ground PHM system uses the pre-built mathematical model to perform fault analysis and processing on the monitoring data of key parts, displays and opens different permissions for different users and pushes corresponding fault information through the application platform And maintenance decision-making, because the mathematical model is obtained by combining the data obtained by monitoring the key systems and parts of railway freight vehicles and the state of the components, as well as the ground data to comprehensively model, so the fault analysis is objective and accurate, avoiding the risk caused by human subjective judgment. error of judgment.

Description

technical field [0001] The present application relates to the technical field of vehicle transportation, in particular to a railway freight car failure prediction and health management system. Background technique [0002] Safety and reliability are the most basic and important requirements for rail transit equipment. With the development of technology, rail transit equipment is becoming more and more complex, and the diversity, comprehensiveness and intelligence of freight trains are constantly improving. [0003] With the increase in the number of trains in operation and the increase in the complexity of the train, more safety factors will inevitably be introduced and the probability of component failure and functional failure in the train will increase. In this case, in order to ensure the safety of the train Therefore, it is necessary to increase investment in the design and production of trains, overhaul and maintenance, and monitoring and operation. At present, most o...

Problems solved by technology

[0004] In view of this, the purpose of the present invention is to provide a railway freight car fault prediction and health management system, which can solve the problem that the existing 5T system for vehicle safety monitoring and early warning system cannot monitor the state of the vehicle in real time, and can solve the problem of the prevention of the existing railway freight car. Excessive maintenance or "vacuum period" of failure maintenance caused by maintenance strategies, optimize the existing truck maintenance system, and realize the transformation from preventive maintenance to condition-based maintenance
