列车通过3JG和1LQ区段时编码电路的设计与硏究

Research on Coding Circuit for Train Passing Through 3JG Section and 1LQ Section

以某双线自动闭塞铁路区间轨道电路设计为例,针对列车正向通过3JG区段和反向通过1L Q区段时出现闪U2的现象进行分析,对编码电路设计时需要注意的事项进行研究,并提出合理可行的设计建议和改进措施,以期对其他类似工程起到参考和借鉴作用。

Taking the design of the track circuit of a double-track railway section with automatic block as an exam ple,the phenomenon of flash U2 when the train passes through the 3JG section in the normal direction or through the 1LQ section in the opposite direction are described and the matters that need attention in design of the coding circuit are also studied.And then suggestions and on reasonable and feasible design as well as improvement measure's are put forward in order to offer reference for other similar projects.
