轨道电路解码测试模块的软件设计

在我国现行的CTCS-2级列车控制系统中,轨道电路作为系统地面设备的重要组成部分,其不仅用来检测轨道的占用与否和列车的完整性,而且还连续为列车提供运行前方闭塞区间空闲数等信息。因此,列控车载系统对轨道电路信息的正确解析是保证列车安全运行的关键。为了检测列控车载系统中轨道电路解码部分是否解码正确,提出了轨道电路解码测试模块,详细阐述了模块的功能,并采用模块化的思想对模块的软件进行了设计。

Software design of track circuit decoding test module

In hte current CTCS-2 train control system,the track circuit is an important part of the train control system ground equipment,which not only used to detect the train tracks are occupied or not and it integrity,but also to provide a continuous information of free number of block section for the train.Therefore,the correct analysis of train control system vehicle for circuit board information is critical to ensure the safe operation of trains.This paper proposes a track circuit decoding test module,presents the module function detail and designed the software based on the module.
