Movement authorization calculating method based on vehicle-vehicle communication CBTC system

Abstract

The invention relates to a movement authorization calculating method based on a vehicle-vehicle communication CBTC system. The method comprises the following steps: S1, receiving information of othermodules by an MA calculating module periodically; S2, judging whether an external train is in a communication range or not by a train, if so, establishing communication between the train and the external train, acquiring information of the external train by a communication module, inputting the information of the external train into an information synchronization module, and achieving informationsynchronization of the trains by the information synchronization module by means of an information synchronization algorithm; S3, verifying timeliness of the information of the external train, and inputting the information of the external train meeting a timeliness requirement into the MA calculating module; and S4, determining the train which is closest to the front side of the train as a dynamicobstacle and determining a turnout in front of the operating train and immobile trains on a line are static obstacles by the MA calculating module according to the information of the train meeting the timeliness requirement, wherein the obstacle which is closer to a locomotive of the train among the two types of obstacles is the closest obstacle, namely an MA terminal point.

Description

technical field [0001] The invention belongs to the technical field of rail transit operation control, and relates to a mobile authorization calculation method for vehicle-to-vehicle communication CBTC. Background technique [0002] At present, Communications-Based Train Control1 (CBTC) is a train operation control system widely used in the field of urban rail transit. There are a large number of ground equipment in this system, which makes the cost high and the maintenance is cumbersome; train-ground -The communication method of the vehicle causes problems such as high communication delay in the system. Vehicle-to-vehicle communication CBTC system is a new type of train operation control system that came into being to solve the above problems. This system uses vehicle-to-vehicle communication technology to enable trains to communicate directly and transmit information about their own positions, speeds, and running directions to each other. information. Then, the on-board ...
