摘　　要：列车测速测距是城市轨道交通信号领域的核心基础功能,在采用一种新的测速测距设备或对既有设备进行替换升级的过程中,应该充分评估新设备或替换设备对系统性能的影响。从列车定位算法及其不确定性分析入手,介绍了一种针对影响位置不确定性的关键因素--定位信标检测窗口的试验方案和统计分析方法。该试验方案对完成列车定位功能的同类型设备的精确度分析具有一定的参考意义。The train speed and distance measurement is the core basic function in the field of urban rail transit signal. In the process of adopting a new speed and distance measurement equipment or replacing and upgrading the existing equipment, the impact of the new equipment or replacement equipment on the system performance should be fully evaluated. Starting from the train positioning algorithm and its uncertainty analysis and based on the key factors that affect location uncertainty, a test scheme and statistical analysis method for positioning beacon detection window are introduced in this paper. The test scheme has certain reference significance for the accuracy analysis of the same type of equipment which completes the train positioning function.
