<p>The present invention relates to a method and an apparatus for maintaining pressure in a high-speed train compartment using pressurization equipment wherein a lifting door is doubly installed at an entrance of a two-story high-speed train for a railroad car to have an air chamber forming an air layer between the double lifting door, and pressure of a frontal region is detected or pressure change and outer pressure change are detected by tunnel location scanning when driving in a tunnel or crossing a vehicle to automatically adjust the air chamber pressure by pressurization equipment, thereby constantly maintaining the pressure in a high-speed train compartment by the air chamber. According to the present invention, an apparatus for maintaining pressure in a high-speed train compartment includes an air chamber unit having an air layer formed by the double lifting door installed at an entrance of a railroad car; a pneumatic pressure detection unit for detecting inside air pressure of the air chamber unit; an outside pressure detection unit detecting outside pressure by air resistance applied to a frontal region when the railroad car is being driven, or detecting outside pressure change and outside pressure change of the railroad car by scanning a tunnel location when passing a tunnel; pressurization equipment injecting air into the air chamber unit to adjust the inside air pressure; and a control unit comparing the inside air pressure detected by the pneumatic pressure detection unit with the outside pressure detected by the outside pressure detection unit to control the pressurization equipment to adjust the inside air pressure of the air chamber unit to get rid of a difference between the two if the difference equal to or greater than predetermined amount is generated.</p> |
