Abstract

The invention provides a train operation overspeed protection hybrid monitor method, and relates to the technical field of rail traffic train operation controlling. According to the train operation overspeed protection hybrid monitor method, firstly, according to mechanical characteristics of a train, a kinematic model of the train is built, and a discrete transition parameter affecting the trainbehavior is determined; based on a verification technique in operation, a control strategy corresponding to current operation information of the train is obtained in real time, and according to the control strategy, by combining the discrete transition parameter, a composite model is established; according to the composite model, EBI speed limiting changing information in front of train operationis calculated, and a non-safe area is determined; an over approximation of a reachable set of the train is calculated; and by using the over approximation of the reachable set and the non-safe area, whether the train behavior is safe or not is verified, and according to the verification result, whether alarm information is needed to be sent out or not is determined. According to the train operation overspeed protection hybrid monitor method, safety verification can be conducted on the train continuous behavior in the train operation process; the train overspeed behavior can be discovered in time; and the safety of train operation is ensured.

Description

technical field [0001] The invention relates to the technical field of rail transit train operation control, in particular to a hybrid monitoring method for train operation overspeed protection. Background technique [0002] The train control system is the core control equipment of railway signals and the safety guarantee of railway operation, among which the train overspeed protection is one of the core functions of the train control system. The equipment carrying the overspeed protection function (generally on-board equipment) monitors the running speed of the train by collecting the current running status and line conditions of the train on the line, and controls the speed of the train by cutting off the traction force and corresponding braking methods to prevent the train from crossing the dangerous road. point, so as to ensure the safe operation of the train. [0003] At this stage, in the process of realizing the train overspeed protection function, the equipment carr...
