Rail transit vehicle and control method and control system thereof

Abstract

The invention discloses a rail transit vehicle and a control method and a control system thereof. When the external pressure of a train fluctuates violently, a driver cab in the train is isolated froma passenger room space while the internal space of the train is completely isolated from the external environment of the train, so that the air tightness of the driver cab is improved; when a fire occurs in the driver cab and the passenger room in the vehicle independently or the driver cab and the passenger room simultaneously, flame and poison gas can be prevented from spreading and diffusing through linkage opening and closing of an air return grille on a partition wall door, a driver cab air channel opening air supply grille, an air inlet valve of an air conditioner fresh air device and an exhaust valve of a waste exhaust device, and poison gas exhaust is promoted; and the life safety of passengers and drivers is protected to the greatest extent.

Description

technical field [0001] The invention relates to the field of rail transit, in particular to a rail transit vehicle, a control method and a control system thereof. Background technique [0002] Nowadays, people have higher and higher requirements for the comfort and safety of rail vehicles. On the one hand, when a vehicle with poor airtight performance passes through a tunnel opening or a tunnel air shaft, due to the pressure wave from the outside changing rapidly into the vehicle, it is easy to cause ear swelling and tinnitus, especially for drivers who have been working in the driver's cab for a long time , This phenomenon will cause hearing damage. Therefore, how to improve the airtight performance of the driver's cab, reduce the damage caused by air pressure fluctuations to the driver's physical health, and ensure the comfort of the ride must be considered in vehicle design. On the other hand, when a fire breaks out in the compartment, how to prevent the spread and sprea...

On the one hand, when a vehicle with poor airtight performance passes through a tunnel opening or a tunnel air shaft, due to the pressure wave from the outside changing rapidly into the vehicle, it is easy to cause ear swelling and tinnitus, especially for drivers who have been working in the driver's cab for a long time , this phenomenon will cause hearing damage. Therefore, how to improve the airtight performance of the driver's cab, reduce the damage caused by air pressure fluctuations to the driver's physical health, and ensure the comfort of the ride should be considered when designing the vehicle.
