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.
