基于DCC的车载ATP线路数据收发和使用处理

DCC-based Processing for Line Data Transmission,Reception and Utilization by Onboard ATP

线路数据是列车能够稳定运行的关键因素,传统的线路数据更新方法通常依赖于稳定的网络通信或大量的人力资源,然而在一些特殊场景中,无线网络不能覆盖或网络通信不够可靠,会存在列车更新线路数据困难的问题,为解决这一难题,研究一种站内存储、区间触发的线路数据更新方法,列车能够在无线网络无法覆盖的情况下及时更新线路数据,从而提高列车的运行效率,对铁路交通系统的稳定运行具有重要意义。

The line data is a key factor for the stable operation of trains.The traditional methods for line data update usually rely on stable network communication or plenty human resources.In some special scenarios,wireless network coverage is not available or network communication is not suffi ciently reliable,which causes difficulties in line data update.To solve this problem,this paper studies a new method for line data update featuring data storage at the stations and data update at the sections.The proposed method enables timely line data update when wireless network coverage is not available.Thus,it improves the operation effi ciency of trains,which has great importance for the stable operation of the railway transportation systems.
