摘　　要：对某车站出现的分路超限报警问题作为典型案例,通过现场的模拟分路测试与数据监测,分别从时域与频率两方面对列车分路超限报警问题进行了分析,将调整、正常分路与分路超限三种情况的功出电压、轨面电压、主轨入和主轨出电压波形进行了对比,最终得出故障原因及改进方案。Taking the shunting overrun alarm problem in a station as a typical case,through on-site simulation shunting test and data monitoring,the train shunting overrun alarm problem is analyzed in terms of both time domain and frequency.The power output voltage,rail surface voltage,main rail input and main rail output voltage waveforms are compared for three scenarios,including adjustment,normal shunting and shunting overrun.Finally,the cause of the fault is determined and the improvement plan is proposed.
