Intelligent human body induction method

Abstract

The invention discloses an intelligent human body induction method which comprises the following steps: S1, continuously acquiring human motion parameters by a 5.8G microwave Doppler radar, performing analog / digital conversion so as to obtain a digital signal, transmitting the digital signal to a digital signal processor (DSP) module, and performing Fourier transform on the digital signal by the DSP module so as to obtain a frequency domain characteristics curve of the digital signal; S2, establishing a BP artificial neural network in an MCU (micro control unit); S3, performing the operation of the step S1, analyzing the newly obtained signal frequency domain characteristics curve through the BP neural network so as to obtain a result whether the human motion exists; S4, calibrating the check result by a user; and S5, reporting the obtained result and the calibration result to an upper computer by the MCU module so as to retraining the neural network. The constructed artificial neural network is continuously corrected and perfected by a manufacturer by virtue of the results fed back by the human radar induction system used by the user, so that the detection accuracy of the human radar induction system is continuously improved.

Description

technical field [0001] The invention relates to the field of induction detection, in particular to an intelligent human body induction method capable of accurately identifying a human body. Background technique [0002] The existing human body sensing radar based on the microwave Doppler effect has been widely used in daily life, such as corridor lights. [0003] With the improvement of people's living standards, smart home systems are gradually entering people's lives, among which smart lighting, security and other facilities need to accurately judge the existence of people. [0004] The microwave Doppler radar currently on the market only performs simple processing on the reflected wave, so it is susceptible to interference and has a high false positive rate, so it is not suitable for use in a home environment. Contents of the invention [0005] In view of the shortcomings and deficiencies in the above-mentioned prior art, the purpose of the present invention is to prov...
