Step S102, control microwave radar receive the microwave signal that object returns, wherein microwave signal is by microwave radar
It sends.
In the 1940s, electromagnetic wave is used to the distance between detect and measure target.They are referred to as " wireless electric-examination
It surveys and ranging ".Radar is a kind of electromagnetic wave system, and electromagnetic signals receive the target covered from its power
Echo, and position and other information are extracted from echo-signal, for detecting, positioning and target identification sometimes.Since microwave has
There is wide bandwidth, penetrate that ionosphere energy is strong, radar is the Typical Representative using microwave property.Microwave in step S102
Signal, that is, electromagnetic wave signal.
According to an optional embodiment of the application.The microwave signal that microwave radar issues occurs after encountering barrier
Reflection, is received by the reflected microwave signal of barrier by microwave radar.
Step S104 extracts the body movement signal of human body from microwave signal, wherein body movement signal include it is following at least it

1-2mm.There is certain physiology coupled relations between the cardiopulmonary of people.The higher hamonic wave of breath signal and the fundamental wave of heartbeat signal
Frequency is completely coincident, and therefore, traditional digital filtering is difficult to isolate heartbeat signal from human motion signal, using adaptive
This problem can be solved in filtering.
The basic thought of adaptive noise cancellation is: will mix noisy original signal (desired signal) and interference signal is same
When input adaptive adaptive noise canceller (ANC), constantly adjusted by adaptive algorithm according to the error of desired signal and reference signal
The weight coefficient of non-recursive type (FIR) digital filter, the interference for approaching reference signal infinitely in desired signal, and error most
Hour output desired signal.According to this thought, adaptively breathing offsets model from human motion letter used in the present embodiment

It holds constant.
Optionally, beats when beats when sleep quality include the sleep quality of different age group.
According to the one of the application, optionally embodiment, human heartbeat are different, people on daytime and evening number
Mostly daytime activity, so daytime beats be higher than the beats in evening.Adult at nominal conditions, men and women
Property beats there is also difference, adult male is about 60-80 times per minute, and women is then relatively high, is per minute
70-90 times.When people enters sleep state, heart rate opposite can be reduced.Male be about it is 50-70 times per minute, women is per minute
About 60-70 times.Unlike adult, baby may be up to 120-140 times per minute, and beats can be with baby
The age of youngster increases and reduces, and when sleeping soundly, heart rate is opposite per minute have been slowed down 10-40 times children.Compared to an adult
For baby, for the beats of the elderly with regard to relatively low, the pulse of the elderly is about 55-60 times per minute.
Therefore, according to the number of heartbeat when sleep quality, heart when a sleep for each person is calculated by long time integration
It jumps, when microwave radar detection is to this pulse rate, automatically switches to defined good sleep pattern.
Correspondingly, if match unsuccessful, illustrate that nobody sleeps in room, do not need the operation mould for adjusting air-conditioning

Formula is different, therefore, after extracting heartbeat signal in back wave, if it is possible to judge the year of human body according to the heartbeat signal of extraction
Age, and then according to the operating status of age setting air-conditioning, user can be preferably improved to the usage experience of air-conditioning, by above-mentioned
Step is matched with the heartbeat signal of extraction with the average beats of the human body of different age group, determines human body in room
Age bracket, the suitable sleep parameters for all age group that parameter or big data analysis when in conjunction with user setting sleep go out are dynamic
The sleep pattern of state adjustment air-conditioning.
Optionally, the corresponding average beats of the human body of different age group determine by the following method: statistics human body is every
The number that the beats and each beats of minute occur in 24 hours；After removing abnormal heartbeats number, each heartbeat is calculated
The probability that number occurs；According to the number of heartbeat per minute and the mean value and variance of probability calculation human body beats per minute；
Mean value and variance are inputted into normal distyribution function, determine that the highest beats per minute of probability occurred are average heartbeat time
Number.
