Online electrified railway overhead contact line icing monitoring system

Abstract

The invention discloses an online electrified railway overhead contact line icing monitoring system. The system comprises a master control unit for a plurality of monitoring terminals connected through a railway private network, and a central data receiving module connected with the railway private network, wherein the central data receiving module is connected with an icing analysis and query module; the icing analysis and query module is connected with a database and is connected with a client through the database; and the client is provided with an alarm module. The monitoring equipment transmits the data to a monitoring center through the railway private communication network by acquiring images of the overhead contact line, the ambient temperature, the humidity, the wind speed, the wind direction and other data, and a monitoring center software system analyzes the icing conditions of the overhead contact line by employing an intelligent video analysis technology and an expert knowledge database, can alarm in modes of sound, short messages and the like and can timely take ice-melting and deicing measures.. Therefore, all-weather monitoring on the overhead contact line icing is realized, the major rail accidents caused by the icing are prevented, and a guarantee is provided for safety operation of the railway.

Description

technical field [0001] The invention belongs to the field of power supply of electric power systems, and relates to an icing on-line detection system, in particular to an icing on-line monitoring system of an electrified railway catenary. Background technique [0002] In recent years, with the extension and development of electrified railways, the catenary has continued to extend to areas prone to and repeated icing, and frequent icing accidents have had a significant impact on the safe operation of electrification. In the spring of 2008, my country encountered severe icing disasters. Catenary lines in Guangdong, Guangxi, Hunan, Hubei and other places were seriously icing, which seriously affected the safe operation of railways. [0003] After the railway catenary is iced, the actual icing of the catenary exceeds the design maximum icing thickness, the mass of the icing increases, and the wind pressure area increases after icing. Uneven icing or different deicing causes tens...

AI Technical Summary

Problems solved by technology

[0003] After the railway catenary is iced, the actual icing of the catenary exceeds the design maximum icing thickness, the mass of the icing increases, and the wind pressure area increases after icing. Uneven icing or different deicing causes tension differences between adjacent spans, resulting in Mechanical and electrical accidents; on the other hand, when the pantograph of the locomotive comes into contact with the ice-coated wire, arcing occurs, which increases the wear and tear on the wire and pantograph, and even causes accidents such as dancing of the catenary and even the collapse of the pole and the collapse of the net.

Once icing causes damage to the power grid, it will seriously affect the safety, reliability, and punctual operation of trains
