基于通信的列车控制模式下的列车定位新技术

摘要

分析了目前常用的列车定位技术的优缺点.介绍了基于多传感器信息融合和基于漏泄同轴光缆的列车定位新技术.对利用漏泄同轴光缆或基于多传感器信息融合测速定位方法实施CBTC(基于通信的列车控制)模式下列车精确定位进行理论探讨,为解决现有采用轨道电路和信标进行列车定位精度不高和初始化过程长等缺点提供了借鉴思路.%With an introduction of the leakage coaxial cables and based on the multisensory information fusion, the present situation of train positioning is discussed. The implementation of CBTC mode for train precise positioning with this new technology is theoretically analyzed, in order to solve the defects caused by the existing adopt track circuit and beacons conduct, such as the low train positioning precision and long initialization process. Finally various standard train positioning systems are compared for the future direction of train positioning technology.
