The invention, which belongs to the technical field of electrified rail transit and power electronic converters, particularly relates to a subway train position detection system which comprises a plurality of first position detection units and a plurality of second position detection units. And the first position detection units and the second position detection units work cooperatively to comparevoltage products output by the two position detection units so as to judge the real-time dynamic position of the train. The method has the advantages of dynamically judging the position of the trainin real time, being accurate in positioning, good in anti-interference performance, small in maintenance amount and the like.
本发明属于电气化轨道交通和电力电子变流器技术领域,具体涉及一种地铁列车位置检测系统,包括:若干个第一位置检测单元和若干个第二位置检测单元。第一位置检测单元与第二位置检测单元协同工作,对两个位置检测单元输出的电压乘积进行比较,进而判断列车的实时动态位置。本发明具有动态实时判断列车位置、定位准确、抗干扰性能好、维护量小等优点。
