Abstract Aiming at the abnormal display of high-speed rail network broadcasting system
caused by electromagnetic interference,some experiments were designed.According to
the test results, the interference source,the pathways,and the sensitive equipment
were found out. Finally, by using the signal and power filters, the crash and jamming
problems of network broadcasting system display were resolved.
Keywords high-speed train; EMC; broadcasting system; Lonworks bus; filtering;
