AN INTELLIGENT ELEVATOR CONTROL SYSTEM BASED ON HUMAN DETECTION

Abstract

This invention provides an intelligent elevator control system based on human body detection By deploying three groups of cameras respectively at the upper station lower station and elevator cabin using two PLC controllers installed in the elevator shaft and top of the cabin The cameras monitor in real time the movement status of people in the station hall waiting area and inside the cabin When a person is detected in the preset sensing area the first PLC controller automatically activates the corresponding call button of the station hall After the third camera group detects a person entering the cabin the second PLC controller automatically activates the target floor button according to the current floor of the elevator and then activates the door closing button after a preset delay time The two PLC controllers achieve collaborative control through data communication via the accompanying cable so that special groups can complete the entire process of taking the elevator without searching for or pressing any buttons This avoids operational difficulties and accidental activation of alarm bells for groups such as visually impaired individuals elderly people and those carrying items and eliminates repeated pressing phenomena when multiple people are waiting
