摘要
针对高速铁路运营以来频繁发生的电气化干扰信号设备问题,以某站车载STM收到2000Hz谐波干扰,导致车载输出异常制动为例,详细分析了制动原因,并从干扰源、干扰路径及被干扰对象等方面展开了方案研究,最终通过在干扰区段增加电码化发码等措施,有效解决了制动问题。
To address the problem of electrification interference to signal system frequently occurring since the operation of high-speed railway,the causes of abnormal braking due to 2000Hz harmonic interferences on on-board STM occurring at a station are analyzed.And the interference sources,interfering path and interfered objects are investigated.Finally,the abnormal braking problem has been effectively solved by adding code generation in the interference section.
