Solution of the communication power supply system
System Description The screen door system is a high-tech product combining advanced knowledge of architecture, mechanics, electronics , materials and information technology, Which is mainly used in the rapid transit area, such as subway, city rail, high-speed railway. The screen door system is installed at the edge of platform to separate the rail area and the waiting area, which effectively reduces power consumption of the environmental control equipments in the station, and prevents ventilation loss of the air-conditioning system, ensuring a comfortable waiting environment for the passengers. The screen door is also a station security system for safe driving and waiting. The screen door system is composed of mechanical structure and electrical control system. Mechanical structure includes: door body, load-bearing structure, top container, ground sill, driving mechanism, gate components, gate lock, manual unlocking device etc. Electrical control system includes: PSC master, PSL local control panel, DCU gate unit, driving motor and screen door
Dinghan screen door system is independently developed by Dinghan Technology, with 3 patents of invention, 2 patents of utility model, 6 patents of appearance and 1 software copyright.
