Design of Multi-Channel Online Monitoring System for Conducted Interference in High-Speed Trains

Aiming at the conducted interference generated during the operation of high-speed trains, a multi-channel online monitoring system for conducted interference applicable to highspeed trains is designed. The monitoring system includes hardware and software design. The hardware module is selected according to the requirements, mainly including signal acquisition module, signal processing module and data transmission module. The software design adopts QT platform to realize the upper computer interface. An experimental platform is set up for verification, and the experimental results prove that the monitoring system can capture the transient interference signal, and the correlation coefficient with the real signal can reach 0.97, which meets the requirements of the train conducted interference monitoring.
