The following description will be made by taking an example of the method for the smart panel wake-up apparatus to execute the smart panel wake-up. Referring to fig. 1, the smart panel wake-up method includes:
s101: the signal variation amplitude and the signal variation width are determined based on the human body detection signal.
Illustratively, a human detection signal output by the signal amplification module is acquired in real time, and the human detection signal is generated by the microwave detection module, amplified and filtered by the signal amplification module, and then read by the panel control processor.
Further, the panel control processor performs analog-to-digital conversion on the human detection signal, converts the human detection signal into a data stream, and determines a signal variation amplitude and a signal variation width of the human detection signal.
S102: and determining a human body approaching state according to the signal change amplitude and the signal change width, wherein the human body approaching state is used for reflecting whether a human body approaching the intelligent panel is detected.

For example, when both the signal variation width and the signal variation width reach the set width threshold and width threshold, it is considered that a human body approaches the smart panel, and a human body approach state reflecting that the human body approaches the smart panel is generated. Assuming that the human body approaching state that a human body approaches the intelligent panel and the human body approaching state that no human body approaches the intelligent panel are represented by the values of '1' and '0', when the signal change amplitude and the signal change width reach the set amplitude threshold value and the set width threshold value, the value of the human body approaching state is set to be 1, otherwise, the value of the human body approaching state is set to be 0, and whether a human body approaches the intelligent panel or stays in front of the intelligent panel can be determined according to the value of the human body approaching state.
S103: waking up a panel module in response to the human proximity state reflecting that a human is proximate to the smart panel.
Illustratively, when the signal variation amplitude and the signal variation width reach the set amplitude threshold value and the set width threshold value and generate a human body approaching state reflecting that a human body approaches the intelligent panel, the panel module is awakened in response to the human body approaching state, so that a user can operate the intelligent panel conveniently.
Above-mentioned, detect the human body through microwave detection module, generate human detection signal to utilize signal amplification module to enlarge human detection signal, confirm whether human body is close to intelligent panel according to human detection signal's variation amplitude and change width, and awaken up the panel module when having the human body to be close to intelligent panel, convenience of customers operates intelligent panel, optimizes user experience.
On the basis of the foregoing embodiment, fig. 5 is a flowchart of another smart panel wake-up method provided in an embodiment of the present application, where the smart panel wake-up method is an embodiment of the foregoing smart panel wake-up method. Referring to fig. 5, the smart panel wake-up method includes:
s201: and acquiring the configured panel sensing distance, and determining the peak value percentage according to the set panel sensing distance.
The panel sensing distance can be understood as a distance range (which can be set by the ratio of the set range and also can be set by a specific distance value) for detecting a human body, for example, the range in which the panel sensing distance can be set is 0.8-0.1 m, and at this time, when the human body is 0.1 m away from the intelligent panel or the panel module, the value of the human body detection signal detected by the panel control processor is a signal peak value.
In this embodiment, the distance range in which the panel sensing distance can be set is divided into a plurality of equal parts, and the percentage corresponding to the distance range is determined according to the configured specific value of the panel sensing distance, so as to determine the peak percentage. For example, the range of 0.8-0.1 m is divided into 100 equal parts, the value of the panel sensing distance can be set as a percentage, and the peak percentage n can be determined according to the selected percentage value, for example, when the maximum human body detection distance (0.8 m) is desired, the value of the panel sensing distance is selected as 100%, then the peak percentage n is determined as 100%, and the smaller the set human body detection distance, the smaller the peak percentage n. In other embodiments, the value of the panel sensing distance may be set to a specific distance value, and the peak percentage n may be calculated according to the ratio of the distance value to the distance range.
S202: the signal variation amplitude and the signal variation width are determined based on the human body detection signal.
S203: and determining the human body signal intensity according to the signal change amplitude and the signal change width.
The human body signal strength provided by the present embodiment includes a first human body signal strength and a second human body signal strength, and the first human body signal strength is higher than the second human body signal strength. Through setting up two signal intensity levels of first human signal intensity and second human signal intensity, can confirm human being and be close the state according to two kinds of circumstances that the human being is fast or slowly close intelligent panel respectively, and the human signal intensity that detects under two kinds of circumstances that the human being is fast and slowly close intelligent panel promptly obtains corresponds to first human signal intensity and second human signal intensity respectively.
Specifically, the determination of the human body signal strength includes steps S2031 to S2032:
s2031: and screening out the human body detection signal with the signal change width smaller than the set width according to the signal change amplitude and the signal change width.
Specifically, the signal change width of the human detection signal is detected, and the human detection signal with the signal change width smaller than the set width is screened out. Assuming that the set width is set to 1ms, after receiving the data stream of the reflected signal and converting the data stream into the amplitude and the width of signal change, the human body detection signal with the waveform width smaller than 1ms is screened out, i.e. the human body detection signal with the waveform width smaller than 1ms is not processed, so that the influence of noise of the human body detection signal on the judgment of the human body approaching state is reduced, and the detection accuracy is improved.
S2032: and if the signal variation amplitude corresponding to the human body detection signal reaches a first set threshold value, determining the human body signal intensity as a first human body signal intensity, otherwise, determining the human body signal intensity as a second human body signal intensity.
Specifically, after the human body detection signal with the signal variation width smaller than the set width is screened out, the signal variation amplitude of the human body detection signal is compared with a first set threshold, and when the signal variation amplitude is greater than or equal to the first set threshold, the human body signal intensity corresponding to the signal variation amplitude is determined as the first human body signal intensity, and the human body signal intensity corresponding to the signal variation amplitude smaller than the first set threshold is determined as the first human body signal intensity.
For example, the signal peak value of the human body detection signal is used as the first set threshold, and when the signal variation amplitude reaches the signal peak value or is within the set range of the signal peak value, the human body signal intensity is determined as the first human body signal intensity, otherwise, the human body signal intensity is determined as the first human body signal intensity.
S204: and determining a preset human body induction strategy according to the human body signal intensity.
The human body sensing strategy provided by the embodiment is used for determining the human body approaching state under the corresponding human body signal intensity, and different human body signal intensities correspond to different human body sensing strategies. When the human body approaches the intelligent panel quickly or slowly, the signal change amplitude change conditions corresponding to the human body detection signals are different within a set time range.
The embodiment determines different human body induction strategies aiming at the condition that the human body is rapidly and slowly close to the intelligent panel, namely, the first human body induction strategy and the second human body induction strategy are respectively set corresponding to the first human body signal strength and the second human body signal strength.

s2051: and according to the first human body induction strategy, determining the human body approaching state reflecting that the human body approaches the intelligent panel based on the fact that the signal change amplitude reaching the first set threshold value is detected within a first preset time range or the signal change amplitude which is continuous and reaches a second set threshold value is detected within a second preset time range.
Specifically, in a first preset time range, if a human body detection signal with a signal variation amplitude reaching a first set threshold value is detected again, or in a second time range, when a human body detection signal with a signal variation amplitude reaching a second set threshold value is continuously detected, it is considered that a human body approaches the intelligent panel, and a human body approach state reflecting that the human body approaches the intelligent panel is determined.

For example, it is assumed that the first preset time range is 0-70ms, the second preset time range is 0-120ms, the first preset threshold is a signal peak value of the signal variation amplitude, and the second preset threshold is (1/2+ (1-n)/4) × signal peak value. Based on the first human body induction strategy, in 70ms, if a human body detection signal with a signal variation amplitude reaching a signal peak value is detected, the human body approaching state is determined to be that the human body approaches the intelligent panel, or in 120ms, if two continuous human body detection signals with signal variation amplitudes reaching (1/2+ (1-n)/4) signal peak values are detected, the human body approaching state is determined to be that the human body approaches the intelligent panel, otherwise, the human body approaching state is determined to be that no human body approaches the intelligent panel.
