摘要
针对动车组广播系统受到电磁干扰导致显示异常,进行试验方案设计,并根据试验结果,定位干扰源、干扰途径、敏感设备,最后采用信号滤波、电源滤波的方案解决了广播系统显示死机、卡滞的问题。
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.
