Product Name : PF300 half height leading screw driving platform screen door system with TS16949 certificate

I. Introduction

These doors help to:

• Prevent accidental falls off the platform onto the lower track area, suicide attempts and homicides by pushing.
• Prevent or reduce wind felt by the passengers caused by the Piston effect which could in some circumstances make people fall over
• Reduce the risk of accidents, especially from service trains passing through the station at high speeds.
• Improve climate control within the station (heating, ventilation, and air conditioning are more effective when the station is physically isolated from the tunnel).
• Improve security - access to the tracks and tunnels is restricted.
• Lower costs - eliminate the need for motormen or conductors when used in conjunction with Automatic Train Operation, thereby reducing manpower costs.
• Prevent litter build up on the track which can be a fire risk.

PF400 Platform screen door is developed by Ivy Machinery based on North America rail sliding door technology combining with Chinese metro system environment. The design philosophy is to build simple, reliable, Environmental, and energy saving system.

Normal operation mode After the train parks within the required range, ATC system will give door opening or closing order to the central control cabinet (PSC). Then PSC gives order to individual DCU to implement the door opening and closing.

System Failure Mode In case the system control fails, the station operator can open and close the platform door using the control panel in the station control room.

Door Unit Failure mode If the individual door has mechanical or electrical problem, the platform operator can open and close door by using local key.

II. Mechanism

• Driving mechanism includes DC motor and multi-head ball screw to achieve smooth motion and high reliability.
• Hanging system includes hanger and guide rod. Hanger is connected to the door panel and meanwhile is also connected to the guide rod through the linear bearing.
• Guiding mechanism consists of lower guide roller and track. When the door panel moves, the roller installed on the low part of door panel will rotate around the guide track.
• Locking and unlocking mechanism include spring locking & solenoid activated unlocking mechanism and emergency unlocking mechanism;
• DCU controls the door movement by getting orders from central control panel.
• The sensitive edge system is part of electrical system.
• Central control Cabinet (PSC) consists of central logic control (PEDC) and monitoring system (MMS). The CAN based technology is used to connect the PSC and DCU.
