摘要
对查询应答器和里程计的定位方式提出一种用接触网定位器辅助列车定位的方法.该方法利用列车行进时检测到的定位器的里程信息校正里程计的误差.为避免背景障碍物的干扰,在接触网定位器检测中采用检查窗技术.这种辅助列车定位技术可大幅度减少地面应答器的数量和提高列车定位的精度.
A train positioning technique was proposed as an auxiliary measure for the train locating system based on balise system and odometer. The technique uses the detected location signal at each registration arm to correct the errors accumulated in the odometer. An inspecting window is used in detection of registration arms to avoid interferences from background objects. This auxiliary locating technique brings much higher precision on train location and requires much less balise devices.
