Intelligent ceiling fan based on human body infrared sensors and control method thereof

Abstract

The invention provides an intelligent ceiling fan based on human body infrared sensors and a control method thereof. The intelligent ceiling fan device can intelligently detect the position of a human body and achieve air supply in an omni-directional mode. The main control part is composed of a temperature detection module, a horizontal stepping motor, a single-chip microcomputer minimal system, a vertical stepping motor, a ceiling fan main motor and the human body infrared sensors. According to the control concept, the sensors installed on a base can detect whether people are in a room in real time, and if it is sensed that people are in the room, a swing head rotates horizontally; after sensing of the sensor installed on the swing head, the horizontal stepping motor stops, the vertical stepping motor works, and the swing head rotates in the direction where people are sensed; after the sensor in the axis of fan blades senses people, the vertical stepping motor stops in the vertical direction, and the ceiling fan main motor starts working; after the sensor in the axis of the fan blades does not sense people, the swing head returns to the original position, the horizontal stepping motor starts working, and the two human body infrared sensors installed on the swing head judge the position of people again; and if it is judged that no people are in the room, the fan stops working.

Description

technical field [0001] This patent relates to the electronic device of the infrared sensor of the human body, which can automatically determine the position of the person and start automatically when it senses a person above the set temperature, stop automatically when there is no one, and can re-adjust the position after the person's position moves. Smart home appliances. Background technique [0002] At present, there are various types of electric fans, but most of them are semi-intelligent, not fully intelligent. With the development of science and technology, intelligent electrical appliances are bound to dominate the market, and electrical appliances with traditional operating methods will be replaced. More importantly, traditional electric fans often fail to meet people's requirements at this stage: first, electric fans have the disadvantage of wasting energy; second, they are not convenient and flexible during use, and the control range is limited; Phase unified to ...

AI Technical Summary

Problems solved by technology

[0006] However, the all-round remote control ceiling fan proposed in the utility patent CN203685626U can only control its rotation and orientation by remote control, and requires continuous manipulation of people to realize the movement and switching of the electric fan. Under the development of today's smart home equipment, it has not been achieved. The requirements of intelligent home appliances fail to automatically work according to people's wishes, which is inconvenient to use and fails to truly achieve intelligence
