Remote Fault Analysis and Feedback System for Urban Rail Transit Vehicles

Abstract

Disclosed in the invention is a remote fault analysis and feedback system of an urban rail transit vehicle. The system comprises a vehicle-mounted device system and a ground device system. The vehicle-mounted device system includes a data acquisition module, a data transmitting-receiving module, and an intelligent display terminal; and the ground device system contains a data transmitting-receiving module, a fault analysis module, and a fault knowledge base. According to the invention, the vehicle-mounted device system collects vehicle data and the ground device system receive the data to carry out analyses continuously; diagnosis is carried out based on a fault tree and fault diagnosis steps; and a diagnosis result can be fed back to a vehicle intelligent terminal in real time. Therefore, accuracy and reliability of the fault diagnosis can be improved.

Description

technical field [0001] The invention relates to data collection and processing technology, in particular to a remote fault analysis and feedback system for urban rail transit vehicles. Background technique [0002] Real-time monitoring and fault diagnosis of urban rail transit vehicles are important guarantees for people's safe operation. The existing safe operation of vehicles mainly depends on on-board fault diagnosis, and there is a lack of research on remote fault diagnosis. [0003] With the rapid development of modern science and control technology, urban rail transit vehicle technology is also constantly improving and strengthening. The composition and structure of urban rail transit vehicles are becoming more and more complex, and the integrated functions are becoming more and more perfect. The comprehensive performance is that urban rail transit vehicles are becoming more and more automated, and these factors have also led to frequent failures of urban rail transit ...
