摘要
提速半自动闭塞区段的列车运行速度由120km/h提高到160km/h后,其接近区段也由1个改设为2个。研究了双接近区段编码电路的设计,并对几种特殊情况下的信号显示关系及码序进行了探讨。
The train speed in the semi-automatic block section has been increased from 120km/h to 160km/h,as a result,two approach sections are set up instead of one.This paper researches the coding circuit design of the two approach sections,and discusses the relationship of the signal show and coding sequence in some special cases.
