The invention provides a train braking system and a braking control method. Related control components such as a change-over valve and a microcomputer control mechanism are arranged on a train; an airbrake valve originally arranged on a train is combined to jointly form a brake system of the train. The microcomputer control mechanism controls the switching valve to be opened based on the networkcontrol instruction to implement straight-through type electric pneumatic braking; the air brake valve implements automatic air brake based on the pressure change in the train pipe. During specific operation, a train is firstly subjected to straight-through type electric pneumatic braking, it can be guaranteed that all the trains receive braking or relieving instructions sent through network broadcasting at the same time, corresponding braking or relieving control is carried out, braking and relieving synchronism of all the trains in the train is almost completely consistent, and running stability of the train is guaranteed; Meanwhile, the pressure change of the train pipe also reaches each train and each air brake valve in sequence for automatic air brake, so that the hot standby redundancy function of train brake is provided.
本发明提供一种列车制动系统、制动控制方法,通过在列车车辆上设置转换阀、微机控制机构等控制相关部件,结合列车车辆上原本设置的空气制动阀共同构成列车车辆的制动系统,进而微机控制机构基于网络控制指令控制转换阀的开启实施直通式电空制动,空气制动阀基于列车管内压力变化实施自动式空气制动,在具体运行时,列车首先进行直通式电空制动,通过网络广播发送的制动或缓解指令能保证每辆车同时收到,并进行相应的制动或缓解控制,列车中所有车辆制动和缓解同步性几乎完全一致,保证了列车运行的平稳性;同时列车管的压力变化也先后到达各辆车,空气制动阀进行自动式空气制动,进而提供了列车制动的热备冗余功能。
