Abstract

The invention relates to a method and system for realizing railway vehicle positioning verification. The method comprises the following steps: obtaining a triggering signal transmitted by a photoelectric sensor, carrying out contrastive analysis on the position of the photoelectric sensor transmitting the triggering signal and a planned driving scheme, and obtaining a control strategy; and sendingthe control strategy to a vehicle controller, so that the actual driving position of the vehicle is consistent with the planned driving position in the driving scheme. According to the invention, thevehicle is positioned in real time according to the triggering signal sent by the photoelectric sensor and then, the position is compared with the planned driving position, so that the purpose of verifying the actual position of the vehicle is achieved; and the actual driving speed of the vehicle is adjusted according to the control strategy, so that the actual driving position of the vehicle isconsistent with the planned driving position, and the purpose of correcting the actual driving position of the vehicle is achieved.

Description

technical field [0001] The invention relates to the technical field of rail traffic control, in particular to a method and system for realizing rail vehicle positioning verification. Background technique [0002] With the rapid development of electronic technology, a large number of electronic control devices are widely used in the automotive field, making the precise control of vehicles and the development of unmanned driving possible. There are generally two schemes for the control of unmanned rail vehicles. One scheme is to arrange a large number of sensors on the rail vehicle, and the vehicle can control itself based on the information collected by the sensors in real time, such as vehicle speed and direction; the other scheme is that the vehicle follows the Drive according to the driving plan planned by the control center. Since the second solution can save the arrangement of a large number of sensors and reduce the cost, the second solution is used more. However, bas...
