System Description

The screen door system is ahigh-tech product combining advanced knowledge of architecture, mechanics,electronics , materials and information technology, Which is mainly used in therapid transit area, such as subway, city rail, high-speed railway. The screen doorsystem is installed at the edge of platform to separate the rail area and thewaiting area, which effectively reduces power consumption of the environmentalcontrol equipments in the station, and prevents ventilation loss of theair-conditioning system, ensuring a comfortable waiting environment for thepassengers. The screen door is also a station security system for safe drivingand waiting.
Dinghan screen doorsystem is independently developed by Dinghan Technology, with 3 patents ofinvention, 2 patents of utility model, 6 patents of appearance and 1 softwarecopyright.
