随着我国经济的迅速发展城市地铁建设水平也在逐步提高。然而地铁车站站台的安全事故频繁发生并且能耗非常高。在这种情况下地铁屏蔽门系统应运而生。随着地铁的日益普及屏蔽门系统作为地铁安全保障和节能措施的重要组成部分已经得到了广泛应用。城市轨道交通站台屏蔽门被安装在地铁、轻轨等交通车站站台边缘将轨道与站台候车区隔离与列车门相对应。地铁屏蔽门系统是车站设备系统之一其主要目的是将车站站台公共区与轨行区隔离简化环

With the rapid development of China's economy, the level of urban subway construction has also been gradually improving. However, safety accidents frequently occur on subway station platforms, and energy consumption is very high. In this case, the subway platform screen door system came into being. As the subway becomes increasingly popular, the screen door system, as an important part of subway safety and energy-saving measures, has been widely used. Urban rail transit platform screen doors are installed at the edge of transportation stations such as subways and light rails, isolating the track from the platform waiting area and corresponding to the train doors. The subway screen door system is one of the station equipment systems, whose main purpose is to isolate the public area of the station platform from the running area, simplify the environmental control system, reduce the operating energy consumption of the station's air conditioning system; reduce the operating noise of the train and the impact of piston wind on the station platform waiting passengers, providing passengers with a more comfortable and safer waiting environment; prevent personnel from falling onto the track to prevent accidents and create conditions for unmanned driving of subway vehicles. This article starts with the basic definition and structure of the screen door system, first introducing the definition, types, composition, and functions of the screen door system. Secondly, it generally introduces the application of screen doors in China and abroad. Then, it mainly introduces the characteristics, operation modes, and interface modes of the screen door system. Through a series of concepts and classifications, readers have a certain understanding of the screen door system. Finally, the application prospects of the screen door system are forecasted and analyzed, and development suggestions are proposed.
