Abstract

The invention provides an automatic train protection method and system. The system comprises a vehicle-mounted controller, speed sampling equipment and a weighing system, wherein the vehicle-mounted controller and the speed sampling equipment are arranged on a train, and the weighing system is arranged on a rail foundation. The speed sampling equipment is used for collecting speed information of the train in real time; the weighing system is used for collecting the weight of the train; the vehicle-mounted controller is used for acquiring a movement authorization position and a braking curve corresponding to each braking mode; according to the speed information of the train, the first distance between the train and the movement authorization position and the braking curve, whether the trainis braked or not and a braking mode are determined; according to the speed information, the weight, the acceleration information, the first distance and the braking mode of the train, the train can be braked in combination with the actual weight of the train, the actual braking acceleration of the train is consistent with the braking acceleration corresponding to the braking mode, frequent use ofemergency braking is avoided, safe driving of the train is ensured, and the running efficiency of the train is improved.

Description

technical field [0001] The invention relates to the technical field of trains, in particular to a method and system for automatic protection of trains. Background technique [0002] The current automatic train protection method is to obtain the braking curve corresponding to each braking mode when receiving the movement authorization position sent by the regional controller, and determine the braking mode of the train according to the speed information and braking curve of the train; The braking energy is determined according to the maximum possible weight of the train, the maximum possible acceleration of the train, speed information, the distance between the train and the movement authorization position, the braking method, etc., and the train is braked. However, in the above method, the reference weight is the maximum possible weight of the train, which is inconsistent with the actual weight of the train; the reference acceleration is the maximum possible acceleration of ...
