【Abstract】 A multi-channel online monitoring system for conducted interference generated during high-speed train operation was designed to monitor the system, including hardware and software. According to the requirements, the hardware module selection mainly included signal acquisition module, signal processing module, and data transmission module. The software design adopted the QT platform to achieve the upper computer interface. An experimental was set up for verification. The test results show that the monitoring system can capture transient interference signals, with a correlation coefficient of 0.97 with the real signal, which can meet the monitoring requirements of train conducted interference.更多还原
