Abstract

The invention discloses a monorail train positioning system and method, wherein the system includes: a first beacon, the first beacon is laid on one side of the uplink track; a second beacon, the second beacon is laid on the downlink On the other side of the track, wherein, the first beacon and the second beacon are laid asymmetrically; the first beacon antenna and the second beacon antenna, the first beacon antenna is arranged at the head car position of the monorail train, and the second beacon antenna The beacon antenna is arranged on the tail car position of the monorail train, and the first beacon antenna and the second beacon antenna are arranged on the opposite sides of the monorail train; the positioning device is used to obtain the beacon read by the first beacon antenna data and the beacon data read by the second beacon antenna, and judge the running direction and position information of the monorail train according to the beacon data read by the first beacon antenna and the beacon data read by the second beacon antenna. According to the system of the invention, not only the algorithm is simple, the positioning efficiency is high, but also the laying quantity of ground beacons can be greatly reduced.

Description

technical field [0001] The invention relates to the technical field of rail transportation, in particular to a positioning system for a monorail train and a positioning method for a monorail train. Background technique [0002] In the traditional rail transit beacon installation scheme, the beacon is installed in the middle of the track. The beacon antenna is installed at the bottom of the train, one set for the head car and one set for the tail car. When the train passes the position where the beacon is located, the electromagnetic wave signal emitted by the vehicle-mounted beacon antenna activates the beacon and transmits absolute position information and other information to the train. [0003] In this type of scheme, when the train is initially positioned or relocated from a fault, it must go through two consecutive beacons to determine the position and running direction of the train. This method of train positioning is relatively complicated, and the number of beacons...
