The invention discloses a railway locomotive real-time positioning method and a railway locomotive real-time positioning system. The railway locomotive real-time positioning method is characterized in that locomotive-mounted ground transponder reading equipment reads position data in a ground transponder arranged at a tunnel portal or in a subway environment and determines the position data as an initial position; the locomotive vehicle-mounted data processing unit is combined with data of a locomotive vehicle-mounted speed sensor to process distance data between the locomotive bottom and the ground surface and between the locomotive bottom and the sleeper surface, wherein the distance data is acquired by a locomotive vehicle-mounted high-frequency laser radar or an ultrasonic radar range finder which is mounted at the bottom of the locomotive and faces the ground and is used for measuring the distance between the locomotive bottom and the ground surface from an initial position to the position of the locomotive; the number of sleepers passed by the locomotive running from the initial position to the position where the locomotive is located can be obtained, and the running distance of the locomotive relative to the initial position is calculated in real time according to the interval standard of laying of the sleepers; the method mainly solves the problem that a locomotive cannot be accurately positioned when running on a station track in environments such as a tunnel and a subway.

    本发明公开了一种铁路机车实时定位方法及系统,具体特征为:机车车载地面应答器读取设备读取到布置在隧道口或地铁环境中地面应答器中的位置数据确定为初始位置;机车车载数据处理单元结合机车车载速度传感器的数据,对安装于机车底部面向地面的机车车载高频率激光雷达或超声波雷达测距仪采集的从初始位置到机车所在位置之间的机车底部与地表以及轨枕表面的距离数据进行处理,可获得机车从初始位置运行到机车所在位置之间所经过的轨枕数量,根据轨枕铺设的间距标准实时计算出机车相对初始位置运行的距离;本发明重点解决隧道和地铁等环境中机车运行在股道上无法精准定位的问题。
