The invention provides a braking control system, method and device for an electric pneumatic braking vehicle of a railway wagon, and belongs to the technical field of railway freight train braking control. The electric pneumatic brake vehicle control system is used for controlling the air charging pressure of the brake cylinder of the electric pneumatic brake vehicle control system, improving the train brake and relieving the wave velocity when the railway wagon adopts the train pipe pressure change to control the vehicle brake. When the target braking pressure is determined based on the vehicle load, the braking rates of all the vehicles can be kept consistent when the train is braked, the train braking is improved when the train is braked, and the wave speed is relieved; by controlling the pressure of the auxiliary air cylinder, when each train is braked, the time for charging air to the target brake pressure by the brake cylinder is the same, and the longitudinal impulse of the train in the braking process is reduced. The hybrid requirement of an electric pneumatic brake vehicle and a 120 valve vehicle can be met, the functions of an existing empty and load vehicle adjusting device are replaced, and compressed air waste caused by shunting is avoided.

    本发明提供一种铁路货车电空制动车辆的制动控制系统及方法、装置,属于铁路货物列车制动控制技术领域。本发明用于铁路货车采用列车管压力变化控制车辆制动时,电空制动车辆控制系统的制动缸充风压力和提高列车制动、缓解波速的控制。本发明能够基于车辆载重确定目标制动压力时,使列车制动时各车辆的制动率保持一致,列车实施制动时提高列车制动、缓解波速;通过控制副风缸压力,使列车各车辆制动时,制动缸充风至目标制动压力所用的时间相同,减小制动过程中列车的纵向冲动。本发明可满足电空制动车辆与120阀车辆混编要求,替代现有空重车调整装置功能避免了分流导致的压缩空气浪费。
