Abstract

A method for controlling a train using a train control system comprises the following steps: obtaining fitting parameters according to train drive related factors (101) which are represented as parameters or coefficients related to a train drive process; acquiring train control data according to the fitting parameters and the factors (102). The method controls the train in a simple manner and prevents the train from being out of control. A device for controlling a train is also provided.

Description

technical field [0001] The invention relates to train control technology, in particular to a train control system vehicle control method and device, belonging to the field of communication technology. Background technique [0002] In the CTCS (Chinese Train Control System, China Train Operation Control System)-3 level train control system, the ATP (Automatic Train Protection, automatic train protection) subsystem monitors the speed of the train, and the ATP subsystem passes the maximum speed limit The speed limit on the curve is used to monitor the train operation, and it is judged whether the current speed of the train is overspeed according to the speed limit. If it is overspeed, overspeed protection will be carried out. [0003] In the prior art, the main method is: repeatedly calculate according to four formulas to obtain the speed curve, and control the vehicle speed according to the speed limit in the speed curve. [0004] However, in the process of controlling the ve...
