[0021] Example
[0022] Such as figure 1 with figure 2 The illustrated urban rail transit inspection trolley positioning system is based on the inspection trolley and track, and includes a photoelectric encoder 1, a beacon 6, a photoelectric proximity sensor 4, 5, and a processor. The photoelectric encoder 1 can be installed in the middle part of the rotating axle 3 of the inspection trolley. The inner diameter of the rotating part of the photoelectric encoder needs to be matched and fastened with the rotating axle. The fixed part of the photoelectric encoder is fastened to the chassis of the trolley through the mounting bracket 2. The encoder is connected to the processor through a wire. The beacons 6 are installed on the rail sleepers at equal intervals. There are two photoelectric proximity sensors: the forward photoelectric proximity sensor 4 and the rear photoelectric proximity sensor 5, which are respectively installed on the front and rear parts of the central axis paral...
