Pressure wave protection system applied to high-speed train

Abstract

The invention relates to a pressure wave protection system applied to a high-speed train, comprising pressure wave air doors, a pressure wave sensor assembly and a pressure wave controller, wherein the pressure wave air doors are respectively arranged on the air inlet and the air outlet of the air-conditioning system of each compartment of a train, and the pressure wave sensor assembly and the pressure wave controller are installed in a cab; the pressure wave sensor assembly is electrically connected with the pressure wave controller; the pressure wave sensor comprises pressure tappings arranged on the inner side and the outer side of the compartment; monitored inner and outer pressure difference parameters are instantly transmitted to the pressure wave controller via the pressure tappings in the form of current signals; the pressure wave controller is provided with a microprocessor comprising a data comparison processing module; the pressure wave controller is electrically connected with each pressure wave air door and sends current signals for opening and closing the air door. High-speed trains can quickly reply the sudden change of compartment inner and outer pressure difference by the pressure wave protection system, maintains stable air pressure in the compartment and greatly controls pressure fluctuation in the train, thus ensuring the riding comfort level of passengers.

Description

technical field [0001] The invention relates to a pressure wave protection system applied to a high-speed train. The high-speed train uses the system to cope with the sudden change of the air pressure difference inside and outside the compartment, so as to ensure the comfort of the passengers. Background technique [0002] In order to ensure the comfort of the occupants, air-conditioning equipment must be installed on high-speed vehicles. In addition to ensuring the temperature and humidity in the vehicle, the air-conditioning equipment also needs to perform intermittent or continuous exhaust and ventilation in the vehicle through ventilation equipment. Take a breath to ensure that the air in the car is fresh. When a high-speed train passes through a tunnel or intersection, it will cause large fluctuations in the external air pressure. The pressure change value is proportional to the square of the train speed. The higher the train speed, the greater the pressure change value...

Problems solved by technology

At present, the pressure wave protection system of the existing technology is not perfect, and the protection measures can only be taken after the pressure in the car has begun to change greatly
