Intelligent diagnosis method and on-line monitoring system for electrified railway contact network cable clamp overheat fault

Abstract

The invention discloses an intelligent diagnosis method and an on-line monitoring system for electrified railway contact network cable clamp overheat fault. The fault on-line monitoring system consists of a remote data server, a remote monitoring computer, a train monitoring computer, a general packet ratio service (GPRS) data concentrator and wireless terminal modules distributed on a contact network, wherein the wireless terminal modules are used for detecting the cable clamp temperature, the ambient temperature, the ambient humidity and the contact network current; and the remote data server finishes intelligent diagnosis and disposal of the cable clamp overheat fault according to the acquired real-time data and historical data and issues the real-time acquisition result and the diagnosis result to the remote monitoring computer. The invention mainly solves the problem that the electrified railway contact network cable clamp overheat fault occurs frequently and is difficult to monitor effectively, so that the state of the contact network cable clamp and the fault development state can be monitored continuously on line, and furthermore, contact network overheat accident is avoided, and operation safety of the train is guaranteed.

Description

technical field [0001] The invention relates to a fault diagnosis and early warning method, in particular to an intelligent diagnosis method and an online monitoring system for an electrified railway catenary clamp overheating fault. Background technique [0002] With the continuous development of science and technology and the large-scale speed increase of railways, the technical level and operating speed of electric locomotives have been continuously improved, and higher and higher requirements have been put forward for the safety of railway traction power supply; especially in recent years. For high-speed rail, the requirements for the safety of traction power supply are more stringent. Once a power supply failure occurs, the consequences will be disastrous. Ensuring the safe and stable operation of traction power supply equipment and providing reliable and stable power supply for electric locomotives is of great significance to the smooth and safe operation of railways. ...

AI Technical Summary

Problems solved by technology

The proposed online monitoring system well solves the problems of catenary current discontinuity and wide-area distribution, which is difficult to monitor online, and satisfies the needs of online monitoring of catenary operation status.
