Problems solved by technology

[0003] Embodiments of the present invention provide a Bayesian game-based train autonomous protection method and system. Aiming at the problem of hidden dangers in train operation safety caused by abnormal vehicle-to-vehicle communication, the Bayesian game is used to actively determine whether each communication process is Abnormal, when the communication is abnormal, correct the wrong train position, so that the corrected train position is within the safe range, so as to realize the active protection of the train

Abstract

The invention provides a train autonomous protection method and system based on Bayesian game. The train autonomous protection method and system aim at solving the problem that train operation safetyhas hidden dangers when train-train communication is abnormal; and the Bayesian game is utilized, whether each communication process is abnormal or not is actively judged, the wrong train position iscorrected when communication is abnormal, so that the corrected train position is in a safe range, and therefore the active protection of the train is realized. According to the method and the system,the Bayesian game is innovatively introduced into the field of train protection, the train-train communication state can be estimated according to the mastered information, the judgment of the train-train communication state is realized by solving the boundary probability and updating the posterior probability, the wrong preceding train position information caused by the train-train communicationstate is corrected, and therefore safe operation of the train is protected.

Description

technical field [0001] The invention relates to the technical field of rail transit autonomous control, in particular to a Bayesian game-based autonomous train protection method and system. Background technique [0002] It has become a consensus that rail transit, as a green transportation mode, plays a key role in the comprehensive transportation system. As the "brain and nerve center" of rail transit, the train operation control system controls, supervises and adjusts the braking mode and running speed of the train through on-board equipment and ground equipment according to the real-time status of the train running on the rail transit line. Ensure the safe and efficient operation of trains. In the communication-based train operation control system (CBTC), the regional control area communicates status information such as train position through vehicle-to-ground communication. According to these information, the regional controller calculates and distributes movement autho...
