Dynamic intelligent fault-monitoring and adjusting system and method for overhead contact system

Abstract

The invention relates to the field of intelligent monitoring, communication and adjustment of high-speed railway power supply and discloses a dynamic intelligent fault-monitoring and adjusting system and method for an overhead contact system. The dynamic intelligent fault-monitoring and adjusting system comprises a front device and a scheduling terminal device; the scheduling terminal device is a computer terminal; the front device comprises a data acquisition module and a data processing and control module; the data acquisition module is used for acquiring state values A and B, temperature, humidity, wind speed, wind direction and locomotive passage of an overhead contact system compensator and acquiring data; the data processing and control module comprises a single-chip microcomputer and a data processing circuit composed of the single-chip microcomputer; the whole data processing and control module is used for processing the data acquired by the data acquisition module and generating and storing corresponding data tables through the acquired data according to the time. The dynamic intelligent fault-monitoring and adjusting system and method has the advantages that faults of the overhead contact system, such as positioner shedding from the broken line, main line or curved line, and terminal anchoring clamp breakage, can be efficiently and accurately detected, the state of the overhead contact system can be accurately judged, and operational safety of an electrified railway is greatly guaranteed.

Description

technical field [0001] The invention relates to the field of intelligent monitoring and adjustment of high-speed railway power supply, in particular to a catenary dynamic intelligent fault monitoring and adjustment system. Background technique [0002] At present, China's high-speed railway is in the leap-forward development stage, especially the comprehensive construction of electrified railway, which provides a strong guarantee for my country's economic development. As one of the core equipment of the electrified railway, the catenary is increasingly important and has particularly high safety requirements. Ensuring the safe and reliable operation of the catenary is the top priority of the safe operation of the electrified railway, and it is also an important mission of contemporary railway power supply personnel. [0003] At present, the real-time intelligent monitoring system for catenary faults is still blank, and catenary faults cannot be timely and accurately fed back ...

AI Technical Summary

Problems solved by technology

At present, my country's electrified railway is an emerging technology. Different power supply methods, different catenary wire diameters, different catenary materials, lengths, etc., under different conditions such as temperature, latitude and longitude, wind speed, humidity, etc., its stretching state does not change. scientific research data
