Automatic revolving door system for use in wall of building, has drive device operable based on signal of position detection device and comprising calculating unit that automatically adjust brake point based on variable parameter

摘要

The system (1) has a drive device (5) for automatically driving a rotary wing (2) between a closed position (XG) and an open position (XO). The drive device comprises a position detection device for detection of a position and/or a velocity of the rotary wing. The drive device is operable based on a signal of the position detection device and braked by a movement of the rotary wing in an opening direction starting from a brake point (XB) before reaching the open position. The drive device comprises a calculating unit that automatically adjusts the brake point based on a variable parameter. The drive device is designed as a revolving door drive or an electrohydraulic drive, i.e. hydraulic pump. The positioning detection device is designed as an absolute value device i.e. potentiometer. An independent claim is also included for a method for operating an automatic revolving door system.
