Abstract

The invention discloses a radar personnel monitoring and measuring system and method. The system comprises a millimeter-wave radar which transmits radio waves through an antenna, reflects the radio waves through an obstacle and receives returned reflected waves through the antenna, a signal separation module which is used for separating a plurality of persons from the reflected wave, a DSP which is used for carrying out Fourier transform, fast Fourier transform and smoothing processing on each separated person signal to obtain the number of persons, the position coordinates of each person, thespeed on the position coordinates and the acceleration data on the position coordinates, a 4G wireless module which is used for uploading the number of the persons, the position coordinates of each person, the speed on the position coordinate and the acceleration data on the position coordinate to a network, and a terminal which is used for monitoring the persons in an area in real time accordingto the number of the persons in the network, the position coordinates of each person, the speed on the position coordinate and the acceleration data on the position coordinate. Personnel in an area can be monitored, pre-judgment, prevention and control are performed in advance, and privacy is protected.

Description

technical field [0001] The invention relates to the technical field of building automation and personnel monitoring, in particular to a radar personnel monitoring and measurement system and method. Background technique [0002] At present, with the progress of society and the development of science and technology, all kinds of products tend to be intelligent, which makes our life more convenient. For example, if buildings can be truly intelligent, what kind of earth-shaking changes will it bring to our lives? Imagine if, in a commercial building, you could know where people are, where they are going, and whether they are safe, building systems could be revolutionized. [0003] Today's sensing technologies in building automation, including passive infrared (PIR), cameras, and active infrared (lidar), face challenges in accuracy, privacy, environmental robustness, and system complexity, making it impossible to Effectively meet the requirements of real intelligence. [0004]...
