Active type residual pressure system for subway flatform

摘要

The present invention relates to an active pressurization system using the platform track portion top slab of the underground railway station; Separating the express train and local train travel space travel space and wanhaeng express train to a track that the train passes through the partition wall in the station of the underground railway station, and the station that communicates with each of the upper slab, the first express train and local train travel space travel space first and second air flow outlet space is formed, the front end of the second air flow outlet space and the first port and the first damper and a rear end having a second port and a second damper comprising, in the second air flow outlet space wanhaeng a third port for the exhaust of a train traveling space is provided, wherein the first air flow outlet area has a fourth port for the exhaust of an express train running space is provided, the sensing from the pressure sensor for detecting the driving pressure of the express train The control board receives a signal to close the first and second ports of the top local train local train running space are not the first and second air damper is open and the third port is opened, the top of the express train running space 4 and opening the port, the first and second ports of the top local train traveling space is open and waiting for a local train the first and second dampers are local train waiting for a local train to drive the air supply and exhaust fan and close to give the traveling space characterized in that in that supply. According to the present invention can solve the express train is an express train running space and actively two people feeling problem to the passengers to adjust the air supply and exhaust by having a local train stops, or the drive train space wanhaeng to pass through.
