System and method for controlling centralized brake of vehicles, a motor train set brake control system

A brake control system of a high-speed train set, comprising:

• a centralized brake control system of a control car, a brake controller, a brake control system of a power car, and automatic electro-pneumatic brakes;
• the centralized brake control system of a control car comprises a pressure acquisition device for acquiring a pressure of a main blast pipe, and a train pipe control device;
• a pressure signal output end of the pressure acquisition device is connected with a pressure signal input end of the train pipe control device;
• a brake signal input end of the train pipe control device is connected with a brake signal output end of a brake controller;
• the train pipe control device is pneumatically connected with the main blast pipe and the train pipe by means of an air channel;
• the brake controller is configured to send a brake request to the centralized brake control system of a control car and the brake control system of a power car;
• the brake control system of a power car is configured to control a pressure value generated by a train brake cylinder according to the brake request and a real-time pressure of the train pipe;
• and
• the automatic electro-pneumatic brakes are installed in the control car and a middle trailer car, and are configured to control an application and release of pneumatic braking of the train according to the real-time pressure of the train pipe.

A centralized brake control method of a control car, comprising:

• receiving a brake request of any car;
• receiving a real-time pressure of a train pipe of any car and calculating a target pressure of the train pipe;
• and
• controlling, through a main blast pipe, a pressure of the train pipe according to the brake request and the relationship between the real-time pressure of the train pipe and the target pressure of the train pipe.
