RAIL TRANSIT VEHICLE AND VENTILATION CONTROL METHOD AND SYSTEM THEREFOR
Document Type and Number:
WIPO Patent Application WO/2022/127140
Kind Code:
A1
Abstract:
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.
