摘要： A system for controlling centralized brake of vehicles, comprising: a pressure collection device for collecting the pressure of a main blast pipe and a train pipe control device. The pressure signal output end of the pressure collection device is connected to the pressure signal input end of the train pipe control device; the brake signal input end of the train pipe control device is connected to the brake signal output end of a brake controller; the train pipe control device is pneumatically connected to the main blast pipe and a train pipe separately by means of an air channel. By means of the solution, the installation space of a trailer is reduced, and the costs are lowered. In addition, the change in the pressure of the train pipe is controlled by an automatic brake control system, the train can operate after being connected to an automatically air-braked coach, according to a brake request output by the brake controller and the detection of the real-time pressure of the train pipe, the change in the pressure of the train pipe is controlled, and a five-line control signal is used, so that flexible marshalling can be implemented.

摘要： Disclosed are a pressure control method and a pressure control device for a braking cylinder of a rail vehicle, and the rail vehicle. The method includes the following steps: acquiring the air charge-release volume of the braking cylinder of the rail vehicle and the air flowrate of the braking cylinder; determining the charge-release duration according to the air charge-release volume of the braking cylinder and the air flowrate of the braking cylinder, and controlling the charge-release working duration of the air charge-release solenoid valve according to the air charge-release duration; when the working duration of the air charge-release solenoid valve reaches the charge-release duration, acquiring the predictive pressure of the braking cylinder, and controlling the working state of the air charge-release solenoid valve according to the predictive pressure.
