Method and system for braking high-speed train and brake control device

Abstract

The invention provides a method for braking a high-speed train, a system for braking the high-speed train, and a brake control device. The method for braking the high-speed train comprises the steps of: receiving a train braking instruction, and acquiring real-time state information of a braking unit; determining target brake force according to the braking instruction and the real-time state information; acquiring the actual electric braking force provided by the braking unit; and determining the air braking force exerted by braking equipment according to the target braking force and the actual electric braking force. According to the method for braking the high-speed train, the system for braking the high-speed train and the brake control device, the braking force can be determined according to the real-time sate of the braking unit of the train; the braking force can be reasonably distributed according to the actual conditions of an electric braking device and an air braking device, thus, the braking distance of the high-speed train can be effectively controlled; the braking efficiency can be improved; and the energy can be effectively saved.

Description

technical field [0001] The invention relates to the field of rail transit vehicle control, in particular to a high-speed train braking method, system and braking control device. Background technique [0002] With the rapid development of rail transit technology, the maximum operating speed of CRH2 EMUs currently in operation in China has exceeded 250km / h. The brake unit of the brake system of the CRH2-200 EMU with a maximum operating speed of less than 300km / h that has been put into operation is composed of a motor car and a trailer. The unit structure of the group's braking system and the corresponding braking control device can no longer meet the requirements of safety and reliability of train operation under higher speed conditions. [0003] For high-speed trains, on the one hand, it is necessary to increase the maximum running speed of the train so that passengers can reach their destination in the shortest time. On the other hand, it is necessary to fully guarantee th...
