RAIL TRANSIT VEHICLE AND VENTILATION CONTROL METHOD AND SYSTEM THEREFOR

Provided are a rail transit vehicle and a control method and system therefor. The rail transit vehicle comprises a cab (9) and a passenger compartment (10); the cab (9) is partitioned from the passenger compartment by means of a middle partition wall (1); a partition wall door (2) is mounted on the middle partition wall; a first grille (3) is mounted on the partition wall door; a second grille (13) is mounted on an air channel opening of the cab (9); and each vane (5) of the first grille and the second grille is connected, by means of a transmission mechanism, to a driving device for controlling the grilles to be opened or closed. When the external pressure of a train fluctuates violently, the cab in the train is partitioned from the passenger compartment while the internal space of the train is completely partitioned from the external environment of the train, such that the air tightness of the cab is improved; when a fire occurs in the cab and the passenger compartment in the vehicle independently or occurs in the cab and the passenger compartment simultaneously, linkage opening and closing of an air return grille on the partition wall door, an air supply grille of the air channel opening of the cab, an air inlet valve of an air conditioner fresh air device, and an exhaust valve of a waste exhaust device are implemented, such that flame and poison gas can be prevented from spreading and diffusing, poison gas exhaust is promoted, and the life safety of passengers and drivers is protected to the greatest extent. Se proporciona un vehículo de tránsito ferroviario y un método y sistema de control para el mismo. El vehículo de tránsito ferroviario comprende una cabina (9) y un habitáculo (10); la cabina (9) está separada del habitáculo por medio de una pared divisoria central (1); una puerta de pared divisoria (2) está montada en la pared divisoria central; una primera rejilla (3) está montada en la puerta de la pared divisoria; una segunda parrilla (13) está montada en la abertura de un canal de aire de la cabina (9); y cada paleta (5) de la primera rejilla y de la segunda rejilla está conectada, por medio de un mecanismo de transmisión, a un dispositivo de accionamiento para controlar las rejillas que deben abrirse o cerrarse. Cuando la presión externa de un tren fluctúa violentamente, la cabina del tren se divide del compartimiento de pasajeros, mientras que el espacio interno del tren está completamente separado del entorno externo del tren, de modo que s
