Online monitoring system for overhead line system and method thereof

Abstract

The invention relates to an online monitoring system for an overhead line system and a method thereof. The method comprises the following steps: establishing a plurality of distributed independent monitoring systems on the overhead line system along the railway, transmitting monitoring information to a nearby signal concentrator, and transmitting the information to a monitoring management center and a big data center through a base station; analyzing and processing the data by the monitoring management center, transmitting a monitoring command, and transmitting the command to the specified independent monitoring system by the base station and the signal concentrator. According to the online monitoring system disclosed by the invention, a real-time state monitoring scheme for key technical parameters of the overhead line system is provided, the operating state of the overhead line system is accurately, reliably and safely monitored in an all-weather manner, and an effective data support is provided for intelligent operation maintenance of the overhead line system; with the adoption of the data analysis processing center based on a big data platform, a brand-new overhead line system data analysis and operation mode is provided, the real-time data, historical data and business data can be unified and integrated, and an effective implementation method is provided for the state of the overhead line system.

Description

technical field [0001] The invention relates to the technical field of electrified railway catenary monitoring, in particular to an online catenary monitoring system and a method thereof. Background technique [0002] The electrified railway catenary is arranged in the open air along the railway line, and the line is long and there is no backup. With the rapid development of electrified railways, especially the expansion of the scale of high-speed electrified railway network, the railway department has put forward higher requirements for the operation safety of traction power supply system. Catenary system is an important part of high-speed railway power supply system. Its infrastructure Maintenance is faced with an urgent need to ensure safety, improve efficiency, and reduce costs. [0003] The catenary system is eroded by wind, frost, rain, snow and other natural environments all the year round, as well as the impact and vibration of the pantograph during high-speed opera...

AI Technical Summary

Problems solved by technology

[0004] At present, catenary monitoring methods at home and abroad include: 1) "manual inspection method", which has low efficiency, poor accuracy, and slow response speed.

2) "Special testing equipment method", this method is to install the equipment on special rail vehicles, such as catenary testing vehicles, comprehensive testing vehicles or catenary operating vehicles, etc., and each competent department is responsible for scheduling, regularly or irregularly It takes a long time to detect the catenary every two times, and the data cannot be returned in real time during the detection process, which has data delay phenomenon and cannot reflect the real-time situation on site

Although relatively accurate catenary detection data can be obtained, the data is not time-sensitive, and the surrounding environment of the line will change with time, such as wind direction, wind force, temperature, humidity, etc. The measured cable tension and dynamic lift The data is only the situation at the time of measurement, and cannot reflect the real-time dynamic situation of the catenary
