AI Technical Summary

Technical Problem

Traditional elevators cannot proactively refuse passengers when there are many people but no overload, which reduces riding comfort, creates safety hazards, and affects operational efficiency.

Method used

The system uses cameras to monitor the number of people, combined with gravity sensors and load-restriction components, including a moving part, a drive part, a support plate, and an indicator plate. It uses a servo motor to drive synchronous transmission to achieve the extension and retraction of the load-restriction components. Combined with door control components and distance sensors, it ensures safe operation.

Benefits of technology

Proactively refusing passengers when the elevator is crowded but not overloaded reduces safety risks, improves elevator operating efficiency, reduces waiting time, and ensures passenger safety and comfort.

Abstract

The utility model provides an elevator crowding rejection device which comprises a lift car, door control assemblies and sliding rails, the lift car is hung in an elevator shaft, the two sliding rails are oppositely arranged in the elevator shaft, the two sliding rails are respectively connected with one side of the exterior of the lift car in a sliding mode, the door control assembly is arranged at the opening end of the lift car, and the two rejection assemblies are arranged in the lift car. The two groups of load rejection assemblies are oppositely arranged, and each group of load rejection assembly is installed in one side wall of the lift car. According to the elevator crowding rejection device, the telescopic rejection assembly is arranged and can be rapidly started when the crowding state occurs, external personnel are prevented from entering an overloaded elevator, safety risks are reduced, safety is improved, meanwhile, the external personnel can be informed, the waiting time for getting on and off people is shortened, and the service life of the elevator is prolonged. The operation efficiency of the elevator is improved.
