Embodiment Construction

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0031] Such as image 3 , the present invention arranges a beacon transponder at a certain ATC-block dividing point on the branch track of the ring station type, and the beacon transponder can prompt the vehicle-mounted system to switch the ATC-block direction at this position, that is, from here The direction of the ATC-block from the start to the next fork is opposite to the direction of the previous ATC-block. The beacon transponder hardware arranged b...

Abstract

The invention relates to a method for achieving annular station vehicle positioning control. The method includes: 1) train positioning: arranging a beacon transponder having an annular station sign position on a setting point of an annular station; 2) positioning and recognition: allowing a vehicle-mounted system to recognize an ATC-block where a train is located before the train enters an annularstation rail in an electronic map; 3) information sending and determination: allowing the vehicle-mounted system to continuously determine if the beacon transponder having an annular station sign position is read or not, searching next ATC-block information according to an ATC-block connection relation defined in the electronic map if not and returning to the step 1), and entering the next step if so; and 4) direction resetting: changing the direction of the next ATC-block into an opposite direction defined in the vehicle-mounted electronic map, and continuously performing searching. Comparedwith the prior art, the method is simple to implement, is low in cost, and is reliable in positioning control.

Description

technical field [0001] The invention relates to the field of vehicle-mounted positioning control of trams, in particular to a method for realizing ring-type station-type vehicle-mounted positioning control. Background technique [0002] In the on-board positioning control of trams, the correspondence between the actual position of the train and the position of the train in the system is realized through the on-board electronic map. In the vehicle map, the line is divided into many ATC sections (called ATC-BLOCK, the same below), and the position of the train on the same ATC-BLOCK is tracked through the ranging function of the beacon transponder and the coded odometer . [0003] The train is positioned at a certain position on a certain section. Three-dimensional measurement is used in the on-board map. One-dimensional is the track and direction of the train, one-dimensional is the name of the ATC-BLOCK, and one-dimensional is the ATC-BLOCK where the train is located. The l...
