Microwave radar induction and infrared induction control system and intelligent fan applying same

Abstract

The invention discloses a microwave radar induction and infrared induction control system, which comprises a microwave radar sensor, a pyroelectric infrared sensor and a central controller, wherein the microwave radar sensor is used for detecting the position and moving speed of an object, and an infrared induction switch is used for sensing an infrared ray with a specific wavelength to detect whether a person enters a sensing area, and the central controller executes instructions according to the signal output of the microwave radar sensor and the pyroelectric infrared sensor. The control system can simultaneously sense whether the human body enters a detected area through the microwave radar sensor and the pyroelectric infrared sensor. Through double judgment, the human body can be moreeffectively identified, the effect of accurate detection can be achieved, and the operation of the load can be controlled; when applied in the intelligent fan, the control system can realize the automatic start of the fan and follow the movement of the human body, a good effect of human body blowing and cooling can be achieved, and the requirements of intelligent life can be met. The intelligent fan provided by the invention is provided with a remote controller, which can facilitate the operation of the remote control fan and is more convenient to use.

Description

technical field [0001] The invention relates to the technical field of intelligent control systems, and more specifically relates to a microwave radar induction and infrared induction control system and an intelligent fan using the system. Background technique [0002] Electric fans are currently the most commonly used electrical appliances in people's families, and they are also indispensable household appliances indoors. The main function of electric fans is that after power is turned on, the fan rotates to accelerate the air flow so that the user can achieve a cool effect. [0003] A traditional floor fan includes: a base, a pole, a machine head and fan blades arranged in the machine head. The swing of the head is to increase the working range of the fan and to cool down a large area by blowing air. The rotation of the fan blades and the swing of the machine head in the traditional mechanically controlled floor fan are carried out by manual adjustment. At present, a leve...

AI Technical Summary

Problems solved by technology

At present, most of the smart electric fans on the market are digital integrated chip-based devices with relatively single functions. They can only mechanically swing and blow air at a uniform speed according to the program, or move in one direction at regular intervals, and cannot be intelligent. According to the position of the human body, the fan blowing direction is controlled. The fan is not humanized enough, and it does not play a good role in blowing and cooling the human body. It can no longer meet people's needs for smart fans.
