基于记忆定位的休眠唤醒区域列车定位建立方案

Train Positioning Establishment Scheme Based on Memorized Location in Sleep-wake Zone

[目的]为提升运能,满足高效运营需求,要求列车被唤醒后能够快速建立定位并恢复有信号防护的模式,因此需研究相应的列车定位快速建立方案。[方法]介绍了既有CBTC(基于通信的列车控制)系统下有人驾驶列车的定位建立方式,分析了两种基于记忆定位的休眠唤醒区域无人驾驶列车定位快速建立方案。[结果及结论]基于美式信标的不动车列车定位建立方案和基于欧式信标的动车1 m列车定位建立方案,均能够安全地实现列车定位快速建立功能,满足高效运营需求。

[Objective]In order to improve transport capacity and meet the demand of efficient operation,it is required that every train can rapidly establish its positioning and restore a signal-protected mode after being awakened.Therefore,it is necessary to study corresponding rapid train positioning establishment schemes for trains.[Method]The positioning establishment method for manned trains under existing CBTC(communication-based train control)system is introduced and two rapid train positioning establishment schemes for unmanned trains in the sleep-wake zone based on memorized location are analyzed.[Result&Conclusion]Both the stationary train positioning establishment scheme based on the AAR(American Association of Railroads)tag system and the moving train positioning establishment scheme for 1 m trains based on Eurobalise system can safely realize rapid train positioning establishment function,meeting the requirements for efficient operation.
