The invention discloses a method and a system for realizing vehicle-mounted positioning control at long and short chains in rail transit vehicle-mounted control, and the method comprises the following steps: a, positioning the current position of a train by a vehicle-mounted positioning control system of the train, and identifying the time when the train enters the next ATC-block; b, after train positioning information is obtained, the train-mounted positioning control system conducts safety calculation on the train, and meanwhile the train positioning information is sent to the ATS; c, the vehicle-mounted positioning control system continuously identifies whether long and short chain flag bit information contained in the broken chain beacon transponder is read or not, and when the long and short chain flag bit information is read, the ATC-block mileage coordinate value of the train passing through the broken chain position is updated based on the mileage coordinate information after the broken chain position so as to distinguish the change of the coordinate value; and d, continuously searching, and returning to the step b. The method has the advantages that the vehicle-mounted positioning control system is prompted to carry out mileage coordinate value switching at the position through the chain scission beacon transponder, and the reliability and the stability of vehicle-mounted positioning control are improved.

    本发明公开了一种用于实现轨道交通车载控制中长短链处的车载定位控制的方法和系统,该方法包含:a、列车的车载定位控制系统对列车当前位置进行定位,并识别列车进入下一个ATC‑block的时机;b、获取列车定位信息后,车载定位控制系统对列车进行安全计算,同时将列车定位信息发送至ATS;c、车载定位控制系统持续识别是否读到断链信标应答器包含的长短链标志位信息,当读到长短链标志位信息,将经过断链处后的列车的ATC‑block里程坐标值基于断链处后的里程坐标信息进行更新,以区分坐标值变化;d、继续搜索,并返回步骤b。其优点是:该方法通过断链信标应答器来提示车载定位控制系统在此位置进行里程坐标值的切换,增加了车载定位控制的可靠度和稳定性。
