Research on Electronic Map of Train Autonomous Circumambulation System

文章介绍了列车自主运行控制系统的核心架构以及针对此系统的车载电子地图设计方案和设备编号原则。列车自主运行控制系统取消了地面核心控制设备,并将其功能移植至VOBC子系统与地面STC子系统,车载设备根据实时接收到的地面安全控制中心STC发送的行车信息自主计算移动授权,减少轨旁设备数量,减少车地之间数据通信的流程,从而在保证列车安全运行的同时提升运行效率,降低设备建设及维护成本。

This paper presents the core architecture of Train Autonomous Circumambulation System(TACS),and the the design scheme of on-board electronic map and the principle of equipment numbering.TACS system conceals the ground core control equipment and transplants the such functions to VOBC and Train safety control(STC)systems.According to the train moving information sent by STC,VOBC can independently calculate the mobile authorization in real time.Therefore,communication between the train and the ground can be simplified and the data transmission time is saved.accordingly.This system ensures the safety running of the train and im-prove the operational efficiency.Meanwhile,the equipment cost and maintenance cost is reduced.
