Description
Technical field
The utility model relates to station platform safety door technical fields, in particular to the Railways Stations that a kind of multiple spot opens the door
The safe controlling device for doors of platform.
Background technique
The commonly used closed shield door of the urban rail traffic projects such as China's subway, light rail and half-height safety door system
System promotes passenger safety and comfort to improve platform automation operation level.
With the fast development of China express railway, in high speed railway station, inter-city train station platform application safety door
Demand also come into being, the safety door system of railroad platform can reduce wind pressure when main track train high speed passes through, noise to station
Platform is waited the influence of personnel, and the suffered air-impingement of trackside building is reduced.Safety door can be waited with security isolation platform area and
The area train Gui Hang avoids irrelevant personnel from intentionally or accidentally entering the area train Gui Hang, improves the safety that platform is waited.Meanwhile it is logical
It crosses the visual apparatus such as the display screen of safety door system and provides train information for the personnel of waiting, provided for the platform personnel of waiting more easypro
Suitable waiting environment.
For city rails such as subway, light rails, the vehicle of a certain route is determining single vehicle, each car door of every train
Between relative position it is identical with car door size, and can be by ATO (automatic train operation device) parking position Lai Tigao
Precision, therefore the shield door that uses of subway platform and safety door can be arranged according to specific vehicle, accomplish sliding door with
Car door corresponds.But the High Speed Railway Trains in China, inter-city train are due to historical reasons, and there are various, railroad platforms
The needs that various train stops platform are faced, and parking position precision is lower than subway, light rail, to railroad platform safety door
Vehicle adaptability require it is higher than existing subway safe door.Current common running train vehicle is numerous, the car door phase of each vehicle
Variant to position, car door size, traditional fixation position shield door, safety door mode are obviously unable to satisfy diversification and need
Ask, only adapt to the subway shield door of single fixed vehicle, safe gate technique can not large area in railroad platform application.This
It is the main reason for current railway station seldom installs safety door.This problem Asia it is other country as Japan, South Korea and I
State Taiwan similarly exists.
