Document Type and Number:
WIPO Patent Application WO/2024/074155
Kind Code:
A1
Abstract:
An indoor monitoring and control system and method. An indoor monitoring apparatus comprises a millimeter wave radar (1) and a calculation unit (2). The calculation unit (2) is configured to: in response to radar signal data sent by the millimeter wave radar (1), analyze, on the basis of a preset separation threshold, a micro-Doppler spectrum signal greater than the separation threshold, said signal being from a micro-Doppler spectrogram formed in a preprocessing step; extract a feature value on the basis of a micro-Doppler time-frequency diagram subjected to background noise suppression; and classify the radar signal data on the basis of a constructed classification model and the extracted feature value to obtain an indoor condition category corresponding to the radar signal data. In the system and the method, there is no need to monitor privacy data of a person such as displacement, azimuth angle, and moving speed, the data processing volume is small, a monitoring result is obtained faster, and the indoor control system collects and calculates main indoor interference factors, such that the accuracy of indoor presence monitoring is improved, and personal experience is more comfortable.
