Problems solved by technology

This technical solution has the following three defects. First, because it uses a heat-sensitive measurement method, it will be interfered by other heat sources in the measured environment; It is difficult to trigger recognition when the human body exists in the measured space all the time; third, it uses passive measurement technology, which can obtain very little information of the measured space, and cannot detect the behavioral characteristics of the human body in the north space

Embodiment 1

[0021] Such as figure 1 As shown, the present invention provides a multi-target human activity sensor device based on radar echo analysis algorithm, which is mainly composed of a front-end radar module, a power supply unit, a data processing and main control unit, and a wireless communication management unit. The module completes the control modulation transmission and reception of the waveform, and the debugging of the radio wave is controlled by the control unit and coupled with the signal processing. When the continuously modulated electric wave is sent to the measured space, the reflected wave is received by the receiving antenna of the front-end radar module, and the digital signal conversion of the received waveform is completed through the analog-to-digital conversion circuit.

[0022] The digital signal is sent to the signal processing and main control unit. The main control MCU first buffers the continuous waveform data into the SRAM to ensure that the data will not b...

Description

technical field [0001] The invention relates to the technical field of data analysis, in particular to a multi-target human body activity sensor device based on a radar echo analysis algorithm. Background technique [0002] The current existing technology is mainly PIR human body sensing technology. The technical principle of PIR is to identify the infrared thermal characteristics of the measured object. The PIR sensor senses the infrared rays emitted by the measured object and converts it into an electrical signal. frame difference to determine whether someone is present. This technical solution has the following three defects. First, because it uses a heat-sensitive measurement method, it will be interfered by other heat sources in the measured environment; It is difficult to trigger recognition when the human body exists in the measured space all the time; third, it uses passive measurement technology, which can obtain very little information of the measured space, and c...
