摘　　要：[目的]当前,CBTC(基于通信的列车控制)列车精准定位技术存在工程建设及改造成本高、产生定位误差等问题,对既有的列车定位手段进行技术升级很有必要。[方法]阐述了当前几种常用的列车定位系统技术。基于TACS(列车自主运行系统)中列车安装了雷达防护设备这一特点,提出了基于雷达测速积分的列车行驶里程算法,介绍了基于里程标记的列车自主定位运行原理。在此基础上,提出了TACS下基于“测速雷达+电子地图”的列车实时定位功能,建立了雷达测速与电子地图匹配的实时定位方法。利用仿真平台,对该功能进行了仿真验证。[结果及结论]仿真测试验证了TACS下基于“测速雷达+电子地图”列车实时定位功能的有效性。[Objective]At present,CBTC(communication based train control)precise train positioning technology is prone to high cost of engineering construction and reconstruction,positioning errors and etc.Therefore,it is necessary to upgrade the existing train positioning method.[Method]The current commonly used technologies for train positioning are described.Based on the feature that the train is equipped with radar protection devices under TACS(train autonomous control system),a train mileage algorithm based on radar speed measuring integral is proposed.The principle of train autonomous positioning based on mileage mark is introduced.On this basis,a train real-time positioning function based on"speed measuring radar and electronic map"under TACS is put forward,and a real-time positioning method with radar speed measuring matching the electronic map is established.The above system is verified by the simulation platform.[Result&Conclusion]Simulation tests verify the effectiveness of the train real-time positioning function based on"speed measuring radar and electronic map"under TACS.
