Coded track circuit of train control center

本文首先从数据流的角度分析了轨道电路编码的编制逻辑,着重研究了列控中心与轨道电路之间的数据通信;接下来对轨道区段进行了模块化仿真建模,分析了轨道电路低频编码的自动调整原则;实现了对区间、车站无进路、车站接车进路、车站发车进路等4个场景下的轨道电路低频编码;通过对郑西线的线路数据进行数字化仿真,验证了该轨道电路编码仿真研究的有效性,并为以后对轨道电路编码的研究提供了一个可靠的实验环境。

Firstly, the paper analyzed the programming logic of track circuit coding from the perspective of the data flow, focused on data communication between train control center and track circuit, implemented the modular simulation modeling of the track section, analyzed the automatic adjusts principle of low-frequency coding to track circuit, realized track circuit low-frequency coding under the four scenarios of section, no route to station, station receiving route, station departure approach by digitizing simulation to Zheng-Xi Line data. The effectiveness of the track circuit coding simulation was validated. It was provided a reliable experimental environment to research on track circuit code for future.
