Intelligent home control system and method based on millimeter-wave radar

Abstract

The invention belongs to the technical field of intelligent identification and control, and particularly relates to an intelligent home control system and method based on a millimeter-wave radar. Thesystem comprises a millimeter-wave radar system, a signal processing system, an artificial intelligence classification system, and a central control system, wherein the millimeter-wave radar system emits linear frequency-modulated continuous-wave signals to a radar illumination scene, receives echo signals reflected by the scene, and obtains intermediate-frequency original data through processing;the signal processing system carries out processing on the original data to obtain feature data, and transmits the feature data to the artificial intelligence classification system; the artificial intelligence classification system carries out offline training and online classification on the millimeter-wave radar feature data, and transmits results to the central control system; and the centralcontrol system carries out real-time system control, monitoring and communication. The intelligent home control system and method based on the millimeter-wave radar provided by the invention has the advantages that non-contact remote control in the field of intelligent home is achieved through the millimeter-wave radar, so that daily life is more convenient, comfortable and intelligent; and the system is applicable to places such as ordinary households, offices, conference rooms, etc.

Description

[0001] field of invention [0002] The invention belongs to the technical field of intelligent identification and control, and in particular relates to a millimeter-wave radar-based intelligent home control system and method. Background technique [0003] With the empowerment of artificial intelligence technology, the smart home industry is developing rapidly, and the ecology is gradually becoming mature. The outbreak of Industrial Revolution 4.0 has made the smart home industry promising. As a new direction of industrial development, smart home has become the trend of future home furnishing trends. [0004] Action recognition, as a way of human-computer interaction control, is playing an increasingly important role. With the development of human-computer interaction, the interactive control mode is changing from traditional contact control to non-contact control. [0005] At present, there are some non-contact control products on the market, such as Microsoft Kinect for hum...

AI Technical Summary

Problems solved by technology

[0006] 1. Methods based on image information such as visible light and depth have high power consumption, high computational overhead, low feature extraction efficiency, limited image processing model capabilities, and are easily affected by factors such as illumination and occlusion;

[0007] 2. The method based on speech recognition is limited by the distance and speed of sound wave propagation, the accuracy of user pronunciation and speech recognition, and is not suitable for noisy and silent scenes;

[0008] 3. Both of the above two methods have the risk of leaking user privacy
