DC Motor Drive Bus Platform Screen Door System Patent Protected For BRT Bus Station

Product Name : DC motor drive patent protected Platform Screen Bus door System for BRT Bus station

I. Introduction

Platform screen doors (PSDs) at train or subway stations screen the platform from the train. They are a relatively new addition to many metro systems around the world; some having been retrofitted to established systems. They are widely used in Asian and European metro systems. The platform doors slide open or closed simultaneously with the train doors.

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.

II. Mechanism

The door operator consists of driving mechanism, hanging mechanism, guiding mechanism, and locking & unlocking mechanism.
