The invention relates to the technical field of rail transit, and discloses a train-ground speed measurement positioning method, which is characterized by comprising the following steps of: respectively arranging a train-mounted radar at the head part and the tail part of a train, and respectively arranging an ATP (Automatic Train Protection) platform and a radar platform at two ends in the train; station equipment and a plurality of radar base stations are arranged beside the track; when an ATP platform breaks down, the radar base station and the vehicle-mounted radar send an obtained distance measurement value to the center radar server for storage through the station equipment in real time, and the center radar server calculates the position of a train according to the stored distance measurement value in combination with configuration data and line data of the radar base station and the vehicle-mounted radar and the turnout state obtained from the OC system. The radar platform monitors the states of the two ATP platforms. According to the invention, the SIL4 safety function that the center radar server calculates the position, the speed and the running direction of the train and manages the train information is realized; after the ATP platform has a fault, the position and the speed of the train are accurately calculated.
本发明涉及轨道交通技术领域,公开了一种车地测速定位方法,其特征在于,包括:在列车的头部与尾部分别设置一个车载雷达,在列车内部两端各设置一个ATP平台和一个雷达平台;在轨道旁的设置有车站设备和多个雷达基站;当ATP平台故障时,雷达基站实时与车载雷达将得到的测距值经由车站设备发送给中心雷达服务器保存,中心雷达服务器根据保存的测距值,结合雷达基站与车载雷达的配置数据、线路数据以及从OC系统获取的道岔状态,计算列车的位置;雷达平台监测两个ATP平台的状态。本发明实现了中心雷达服务器计算列车位置、速度、运行方向和列车信息管理的SIL4安全功能;在ATP平台后故障后,准确计算列车的位置和速度。
