AI Technical Summary

Technical Problem

During peak hours, passengers are prone to mistakenly boarding elevators that are not their intended destination, resulting in a reduced passenger experience and reduced elevator operating efficiency. Existing technologies are difficult to effectively avoid this problem and increase the computational load of the elevator group management system.

Method used

By assigning unassigned elevator requests to the earliest returning elevator, the time interval or position between it and the adjacent elevators when it returns to the main station after completing passenger transportation meets a certain threshold condition, and its return time and position are adjusted to prevent passengers from mistakenly boarding the wrong elevator.

Benefits of technology

It effectively prevents passengers from mistakenly boarding non-target elevators, reduces the computing load of the elevator group management system, and improves elevator operation efficiency and passenger elevator experience.

Abstract

This invention discloses an elevator group management method that assigns unassigned passenger requests to the earliest returning elevator, ensuring that the time interval between the return time of the earliest returning elevator after completing passenger transport and the return time of an adjacent elevator returning to the main floor is not less than a time threshold, or that the horizontal distance between the position of the earliest returning elevator at the main floor and the positions of the adjacent elevators at the main floor is not less than a distance threshold; the earliest returning elevator refers to the elevator that returns to the main floor earliest. The technical problem this invention aims to solve is how to effectively prevent passengers from mistakenly boarding non-target elevators while simultaneously reducing the computational load on the elevator group management system during peak usage periods.
