一种基于动态学习的列车定位方法

A Train Location Method Based on Dynamic Learning

列车定位是城市轨道交通信号系统ATP子系统的重要安全功能。针对既有的定位方法,为了解决既有方案定位误差偏大,线路铺设大量定位应答器的问题,提出一种动态学习与调整的列车定位方法。通过动态计算列车实际定位误差并实时根据误差调整列车定位精度,提高列车的定位精度。

Train location is an important safety function of ATP subsystem in urban rail transit signal system.For existing positioning methods,in order to solve the problem that the positioning error of existing schemes is too large and a large number of balise are laid on the lines,a dynamic learning and adjustment method for train positioning is proposed.By dynamically calculating the actual positioning error of the train and adjusting the positioning accuracy of the train in real time according to the error,the positioning accuracy of the train is improved.
