Automatically opening and closing elevator based on infrared sensor detection

Abstract

The invention discloses an automatically opening and closing elevator based on infrared sensor detection. The automatically opening and closing elevator comprises a stop floor carriage door and a stop control panel arranged at each floor, and a carriage which is arranged inside an elevator shaft and can move up and down, and a central processor for controlling the ascending and descending states of the carriage. The stop floor control panel is provided with an infrared sensor for detecting whether there are people around the stop floor carriage door. The central processor is provided with a processing module for receiving detection signals from the infrared sensor and judging whether a stop instruction inputted from the stop floor control panel is valid based on the detection signals. When the infrared sensor outputs the detection signal indicating that there is nobody nearby, the processing module of the central processor immediately cancels the stop instruction inputted by the stop control panel at the floor based on the detection signal, and keeps executing other instructions, thereby avoiding unnecessary stops of the elevator, saving time for passengers inside the elevator, and also increasing the running efficiency of the elevator.

Description

technical field [0001] The invention relates to an elevator, in particular to an elevator that automatically controls the on-off switch based on infrared induction detection. Background technique [0002] In modern society, the use of elevators is very extensive, it can be said that it is inseparable from people's daily life, and has become a ubiquitous device for transporting people and goods in multi-storey buildings. The elevator is an intelligent and automatic equipment controlled by a microcomputer. It processes various instructions through the central processing unit and does not require special personnel to operate and drive. Ordinary passengers only need to press the button on the panel of a certain floor, and then enter the floor to be reached in the elevator. However, the elevator in reality does not intelligently recognize whether someone is waiting for the elevator in front of the elevator door on a certain floor. When someone presses the elevator button on a ce...

Problems solved by technology

However, the elevator in reality does not intelligently recognize whether someone is waiting for the elevator in front of the elevator door on a certain floor. When someone presses the elevator button on a certain floor and then walks away from another elevator that arrived earlier or left without intending to take the elevator , but the button that has been pressed remains, and the elevator will still stop at this floor, which increases the meaningless waiting time of passengers in the elevator and leads to low efficiency of elevator operation
