Abstract

The invention provides a high-speed train and an emergency braking method and system for the high-speed train. On the basis of conventional braking, a main umbrella device and an air injection deviceare additionally arranged, the main umbrella device is not opened in the normal state, the air injection device is not started, and the aerodynamic configuration of the train is not affected; when anemergency situation occurs, different braking modes are correspondingly started according to different levels of the emergency situation, the wind resistance is greatly increased through the main umbrella device and the air injection device, the braking distance is greatly shortened, the braking effect and the train operation safety are greatly improved, the wind resistance braking mode saves energy and is environmentally friendly, and the mechanical wear of the train and rails is reduced. Obstacles are recognized and obstacle distances are detected based on a visual unit, different braking modes are started according to the obstacle distances, and intelligent and automatic braking under emergency conditions is achieved.

Description

technical field [0001] The invention belongs to the technical field of train braking, and in particular relates to a high-speed train and a high-speed train emergency braking method and system. Background technique [0002] The rapid development of high-speed trains has greatly promoted the way of travel and social development, and its safety has attracted much attention. In an emergency, a shorter braking distance means a higher safety factor. The essence of train braking is the transmission and dissipation of kinetic energy. At present, the main braking methods include: disc braking, resistance braking, regenerative braking, magnetic rail braking, track eddy current braking, rotating eddy current braking, wing plate Braking, etc. These braking methods have their own characteristics, and the braking efficiency is also different. [0003] Conventional braking methods can meet the needs of high-speed trains under normal conditions, but when encountering an emergency, it is d...
