The invention relates to the technical field of train aerodynamic effect control in a high-speed railway tunnel, in particular to a method and system for regulating and controlling air pressure in a compartment when a high-speed train passes through the tunnel. The method for regulating and controlling the air pressure in the compartment when the high-speed train passes through the tunnel comprises the steps that the time t when the train is about to enter the tunnel is obtained from a high-speed train control system; the t is compared with the t0; when the t is larger than the t0, the compartment ventilation system is controlled to be kept in a normal mode; when t is smaller than or equal to t0, the compartment ventilation system is controlled to be switched to be in a depressurization mode until the train drives into the tunnel, and the compartment ventilation system is controlled to be switched to be in a normal mode; t0 is the predicted duration of the compartment ventilation system running in the pressure reduction mode, and the pressure reduction mode is a working mode that the compartment ventilation system continuously exhausts air outwards and the air pressure in the compartment is reduced at the speed which can be accepted by human ears.
本发明涉及高速铁路隧道内列车气动效应控制技术领域,具体涉及一种高速列车过隧道时车厢内部气压的调控方法及系统。该高速列车过隧道时车厢内部气压的调控方法包括:从高速列车控制系统获取所述列车即将进入隧道的时间t;比较所述t和t0的大小:当t>t0时,控制所述车厢通风系统保持正常模式;当t≤t0时,控制所述车厢通风系统切换为降压模式,直到列车驶入隧道,控制所述车厢通风系统切换为正常模式;所述t0为预计的车厢通风系统运行在降压模式的时长,所述降压模式是车厢通风系统持续向外排风,以人耳能接受的速率使车厢内部气压下降的工作模式。
