The prior art mainly realizes the user identity confirmation by utilizing visible light images through a face recognition technology, has less related technologies for completing the user recognition by utilizing infrared images, and brings huge challenges to the infrared image recognition process because the infrared images are greatly lost compared with the visible light images; when the heart rate of a user is detected by using a millimeter wave radar to judge whether the user is in a sleep state, the system acquires a time point every time when the user is awakened, and when the awakening time is longer than a certain common time period (the time period when the user is detected and the user does not fall asleep is called the common time period), the voice recognition system enters deep sleep; when the infrared image processing module detects that no user is indoors or the millimeter wave radar system detects that the user is in a sleep state, the time period for the voice recognition system to enter deep sleep is shorter than the time period for the voice recognition system to enter deep sleep. And the voice recognition system is in an easy-to-wake state in the rest time periods.
The invention adopts millimeter radar and an infrared image processing module to combine with a self-adaptive adjusting voice recognition intelligent air conditioner, the heartbeat and the amplitude of a user are detected through millimeter radar waves to identify the direction of the user and the state of the user according to the detection result of the millimeter radar waves, the threshold value of the awakening word of the air conditioner with the voice recognition device is adjusted in a self-adaptive manner to reduce the false awakening rate of the air conditioner with the voice recognition device, and when the infrared image recognition system does not detect the user or the user does not awaken the air conditioner with the voice recognition device for a long time, the threshold value of the voice awakening word of the air conditioner is automatically increased at this time, so that the voice system of the air conditioner with the voice recognition device is in a deep sleep state; when the user wakes up continuously, the threshold value of the voice wake-up word of the air conditioner with the voice recognition device can be automatically reduced, and the air conditioner with the voice recognition device is in an easy wake-up state.

The method comprises the steps of preprocessing an infrared image, then importing the infrared image into a module with a thermal infrared image recognition function, wherein the structure of a thermal infrared model is that a residual layer in a YOLOv5 network is replaced by a dense rolling block, constructing a feature pyramid containing 5 rolling layers with different scales, fusing the feature pyramid with a deep dense network, classifying the fused features by utilizing a Softmax function, forming a deep-fusion rapid target detection model, and detecting whether a user exists indoors.
According to one or more embodiments of the present invention, the millimeter wave radar detection apparatus is based on the detection of heartbeat and respiration by a millimeter wave radar, and may directly extract the doppler shift information of the echo signal to obtain data of heartbeat and respiration through a continuous wave detection mode (CW), or may extract information of respiration and heartbeat corresponding to different amplitudes through an adjustable continuous wave detection mode (FMCW). Because the signal frequency of test is very low and the amplitude is little, the human breathing and the heartbeat that the radar detected can obtain regular breathing and the clear visible data of heartbeat waveform, because the heartbeat rate is lower than the respiratory rate, so the cycle waveform of slow speed is respiratory information, and the quick waveform that superposes on it is heartbeat information. After proper filtering processing, the individual respiration and heartbeat rates can be extracted, and by setting a threshold value, the sleep state of the user is judged when the heart rate of the user is lower than 60.
According to one or more embodiments of the present invention, the millimeter wave radar detection device is mainly based on a phase change of an FMCW signal in a specific range caused by minute vibration of a target. Wherein, isbWhere [ Delta ] [ phi ] is 4 pi/[ lambda ] Delta RbFor phase changes, Δ R is the change in displacement caused by the heart or chest. The jumping signal can be regarded as a sine with frequency and phase, the heart rate can be obtained through change, and the heart rate is obtained to judge the sleep state of the user.
