摘要
结合现场施工导通过程中的2个案例,说明了站内电码化电路、区间ZPW-2000轨道电路在缺少列控条件的情况下如何设计和施工。又结合日常维修一个典型的故障案例,说明了移频电码化问题是如何动态影响轨道电路,使轨道电路动态出现红光带的,为处理类似的故障提供思路。
In combination of two cases of break-over in on-site construction,it is explained how to design and conduct the construction of coded track circuit within station and coded track circuit of ZPW-2000 circuit in section without the support of train control. In addition,It is also explained how the problem of frequency shift coding affect track circuit dynamically and cause the occurrence of red light strip to track circuit,providing ideas for dealing with similar faults.
