AI Technical Summary

Technical Problem

When the motor of the existing access control device fails, the revolving door cannot operate, which obstructs the passage of people and poses a safety hazard, especially affecting evacuation efficiency in emergency situations.

Method used

Design a multifunctional access control device, comprising a frame, a rotating rod, a drive unit, a turntable, and a base. The drive unit drives the rotating rod and the revolving door to rotate, and in the event of a motor failure, the turntable can be manually operated to drive the device, thereby opening and closing the revolving door.

Benefits of technology

Even in the event of a motor failure, personnel can still manually operate the turntable and drive mechanism to ensure that the revolving door can be opened and closed normally, avoiding passage obstruction caused by motor failure and improving evacuation efficiency in emergency situations.
