Problems solved by technology

In recent years, in railway operation, the abnormal operation of signal equipment caused by electromagnetic interference is relatively frequent. Among them, the transient electromagnetic interference generated by trains under some special working conditions is particularly obvious, which brings great hidden dangers to driving safety.
[0003] At present, the real-time monitoring of transient electromagnetic interference generated by trains running in special sections is still blank

Abstract

The invention discloses a ground train transient impulse interference field intensity analysis system. The system comprises an impulse interference capture module used for capturing impulse interference information of a steel rail on a railway or other interference transmission routes in real time, a frequency domain analysis module used for receiving the impulse interference information and analyzing the frequency domain of the impulse interference information, a time domain analysis module used for analyzing the time domain of a frequency domain analysis result, and a transient interference analysis module used for conducting transient interference analysis according to the frequency domain analysis result and a time domain analysis result. By the adoption of the system, a tester can completely master the characteristics of the time domain and the frequency domain of transient interference generated in the running process of a train, influences generated by the interference on related equipment of a railway signal system can be further analyzed, effective signal equipment anti-interference protective measures are provided, the electromagnetic environment of the signal system is improved, and it is guaranteed that the functions of the signal equipment are normal.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to a ground train transient pulse interference field strength analysis system. Background technique [0002] With the rapid development of my country's high-speed railways in recent years, the safety of high-speed railways has increasingly become the focus of social and public attention. As the infrastructure of railway transportation, the signal system bears the heavy responsibility of ensuring dispatching, commanding and controlling train operation, and its safety during operation is very important. The increase of traction power and traction current caused by the increase of operation speed of newly-built passenger dedicated lines makes the external electromagnetic environment of the signal system more complex, and the electromagnetic compatibility of the signal system becomes more important. In recent years, the abnormal operation of signal equipment caused by electromagne...
