摘　　要：TDCS/CTC调度指挥网、TCC信号安全数据网、信号集中监测网三大信号系统网络广泛覆盖于全路的各个车站,极大地提高了铁路运输效率,也产生了网络传输的各种故障,尤其是网络通道丢包。针对信号系统网络通道丢包故障,结合信息设备多年维护经验,总结应急故障处理与日常维护检查的重点方面,提出相应的维护建议。Three major signal system networks of TDCS/CTC network, TCC signal security data network and signal centralized monitoring network cover all stations of the whole railway network, greatly improving the efficiency of railway transportation. Meanwhile, there are lots of network transmission faults, especially network channel packet loss. For the problem of signal system network channel packet loss, the paper summarizes the key aspects of emergency fault handling and routine maintenance check and puts forward maintenance recommendations combined with information equipment maintenance experience for many years.
