The invention relates to a train internal and external pressure difference control ventilation system and method, and the system comprises a pressure difference collection module which is used for collecting a train internal and external pressure difference value; the analysis module is used for receiving the difference value of the internal pressure and the external pressure of the train acquired by the pressure difference acquisition module, judging a threshold value, outputting a control instruction, receiving an execution signal and outputting the control instruction to the execution module through the execution signal; the execution module is used for receiving the control instruction of the analysis module and controlling opening and closing of a pneumatic air valve through a relay. Through the design of the train internal and external pressure difference control ventilation system and method, when the pressure environment near the train changes, the sudden change of the internal and external pressure difference of the compartment can be rapidly dealt with, the fluctuation of the pressure in the train is effectively controlled, the stability of the air pressure in the compartment is maintained, and the influence of the fluctuation of the external pressure on passengers in the train is reduced; therefore, the riding comfort of passengers is improved.

    本发明涉及一种列车内外压差控制通风系统及方法,包括压差采集模块,用于采集列车内外压力差值;分析模块,用于接收压差采集模块采集的列车内外压力差值,并进行阈值判断,输出控制指令,同时还用于接收执行信号,通过执行信号能够向执行模块输出控制指令;执行模块,用于接收分析模块的控制指令,通过继电器控制气动风阀的启闭。本发明通过列车内外压差控制通风系统及方法的设计,当列车附近压力环境发生变化时,可以极其快速地应对车厢内外气压差的骤变,有效控制车内压力的波动,维持车厢内气压的稳定,降低外界压力波动对车内乘客的影响,从而提高了乘客乘坐的舒适度。
