The invention relates to a pressure control system and method for a low-pressure cabin, and the system comprises a cabin body, a cabin door, an air inlet valve, an electromagnetic flow valve, an air pressure sensor, and a controller, and the controller transmits a control instruction to a control instruction receiving end according to an air pressure value collected by the air pressure sensor anda preset target air pressure value. The electromagnetic flow valve adjusts the air inflow of the flow channel according to the control instruction. The design of additionally arranging a transformer and a heat dissipation structure thereof is not needed, and the manufacturing cost is reduced. 本发明涉及一种低压舱的压力控制系统及方法，其系统包括舱体、舱门、进气阀、电磁流量阀、气压传感器和控制器，控制器根据气压传感器采集的气压值和预设的目标气压值，向控制指令接收端发送控制指令；电磁流量阀根据控制指令调整流量通道的进气量。本发明无需额外设置变压器及其散热结构的设计，降低制造成本。
