B503 HALF-HEIGHT SCREEN PLATFORM EDGE DOORS

概要

論文の詳細を見る
This is a breast-high barrier unit which is installed at the rail side edge of the platform. Since the unit is light-weight, large-scale platform reinforcement works are not required for installation to existing stations. High reliability is required to this equipment not to disturb train operations. For door driving, therefore, we adopted a simple high-reliability mechanism using ball screws. For passenger safety, we realized detection of gentle door hit and passenger's getting caught in the door pocket by means of the AC servo motor which drives the ball screw.
