Embodiment Construction
[0047] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.
[0048]It should be noted that the train control system based on train-to-vehicle communication breaks through the traditional regional controller centralized train operation control theory, and establishes a new system control model with train autonomous control as the core. The on-vehicle ITP system of vehicle-to-vehicle communication independently performs path planning, path locking, and front vehicle identification according to the operation plan issued by ITS, the switch information sent by the ground OC, and the train information, and then calculates the movement authorization of the train. Different from the method in the traditional CBTC system in which the gr...

The embodiment of the present invention discloses a method and device for determining mobile authorization based on vehicle-to-vehicle communication. The method includes: identifying sources of danger during train running based on vehicle-to-vehicle communication; Determining the position of the movement authorization related point; according to the position of the movement authorization related point, determining the closest relevant point from the train as the movement authorization end point of the train from the movement authorization related points. The mobile authorization determination method based on vehicle-to-vehicle communication provided by the embodiment of the present invention optimizes the logical calculation process compared with the processing method of traversing forward from the vehicle body to find feasible points in the technology, making the determination process of the mobile authorization end point simpler and more flexible. Improve the efficiency of program operation.
Description
technical field [0001] The invention relates to the technical field of train control, in particular to a method and device for determining mobile authorization based on vehicle-to-vehicle communication. Background technique [0002] With the development of my country's rail transit, the train control system CBTC (Communication Based Train Control) based on wireless communication has gradually become the development trend of my country's urban rail transit control system. The CBTC system adopts high-precision train positioning and continuous two-way communication between trains and grounds, which greatly improves the driving efficiency. [0003] Movement Authorization MA (Movement Authority) means that a train is authorized to enter and pass through a specific track section according to a given running direction. Movement authorization is issued and supervised by ZC before each communication cycle, and CC executes movement authorization to maintain safe train intervals and p...
