An automatic exhaust air door control device comprises a core body (8), an inner door body (2), and an outer door body (1). The core body is fixed on an air door opening of an exhaust air door. The top of the outer door body is movably hinge-connected to an outer side of the core body. The bottom of the inner door body is movably hinge-connected to an inner side of the core body. When no pressure waves are present on the outer side of the core body, both the outer door body and the inner door body open. When pressure waves are present on the outer side of the core body, the outer door body and/or the inner door body is automatically closed in a sealed manner due to the pressure difference between the inner side and the outer side of the core body. A vehicle body having the device is also disclosed. The device automatically controls, by use of a purely mechanical structure and according to fluctuation characteristics of pressure waves at a vehicle exterior, opening and closing of an exhaust ...

Provided are a method, device and system for protecting an interior pressure of a rail vehicle. The method comprises: acquiring the current position of a rail vehicle that is running; if it is learned, by means of determination, that the rail vehicle is located at a pre-set position before reaching a pressure fluctuation control interval, and the current running speed of the rail vehicle is greater than a pre-set speed threshold, turning off an electrical pressure wave protection valve, wherein the pressure fluctuation control interval is determined according to a pre-set pressure fluctuation interval; and if it is learned, by means of determination, that the rail vehicle runs away from the pressure fluctuation control interval, turning on the electrical pressure wave protection valve. According to a pre-set rule, an electrical pressure wave protection valve is pre-turned off before running into a pressure fluctuation control interval and the electrical pressure wave protection valve is ...
