The sleep-assisting device in the above embodiment includes: the device comprises a shell, a detection circuit, an energy conversion device and a processor; the energy conversion device is connected with the detection circuit, the energy conversion device and the detection circuit are respectively connected with the processor, the energy conversion device, the detection circuit and the processor are arranged inside the shell, reflected energy of the energy conversion device can be obtained through the detection circuit, then whether the head of a user is positioned on the energy conversion device is judged by the processor, and then different working states of the energy conversion device can be realized according to whether the head of the user is positioned on the energy conversion device, especially, when the head of the user leaves the working range of the sleep-assisting device, the output power of the energy conversion device can be reduced or the energy conversion device is in a closed state, and the purpose of saving resources is achieved.
During the use of the sleep-aiding device, the processor 4 can determine whether the head of the user is located on the energy conversion device 3 according to the reflected energy, and then control the operation state of the energy conversion device 3 according to the determination result.
Optionally, controlling the energy conversion device 3 to continuously output energy when the head of the user is on the energy conversion device 3; alternatively, the energy transforming device 3 is controlled to periodically output energy when the head leaves the energy transforming device 3.
For example, the detection circuit 2 acquires the reflected energy of the energy conversion device 3 and transmits the reflected energy to the processor, the processor 4 may compare the reflected energy with a calibration value stored in the processor 4 in advance, determine a difference value between the reflected energy and the calibration value stored in the processor in advance, if the difference value is greater than a preset threshold, it indicates that the head of the user leaves the energy conversion device 3, and the processor 4 may control the energy conversion device to periodically output energy; alternatively, if the difference value is smaller than the preset threshold, it indicates that the head of the user is located on the energy conversion device 3, and the processor may control the energy conversion device 3 to continuously output energy.
In one embodiment, based on fig. 1, as shown in fig. 2, the detection circuit 2 includes a radio frequency device 20 and an energy harvesting device 21; the radio frequency device 20 is connected with the energy conversion device 3; the radio frequency device 20 is configured to receive the reflected energy of the energy conversion apparatus 3 and transmit the reflected energy to the energy collection device 21; the energy harvesting device 21 is used to harvest the reflected energy.

The circulator is a multi-port device which transmits incident waves entering any port of the circulator into the next port according to the direction sequence determined by the static bias magnetic field, and is characterized by being capable of transmitting high-frequency signal energy in a single direction and having good application in micro-optical fibers, electronic circulators, isolators, duplexers and reflection amplifiers. As shown in fig. 3, a schematic transmission scheme of the circulator and the energy conversion device is provided. The circulator is a three-port device with unidirectional transmission characteristics, which means that the device is conductive from the first port 200 to the second port 201, from the second port 201 to the third port 202 and from the third port 202 to the first port 200, and isolated in the reverse direction.
Fig. 4 provides a schematic diagram of a detection circuit for illustrating the circuit signal transmission process of the circulator and the energy conversion device. Specifically, during the operation of the sleep-assisting device, the power output port outputs energy, and the normal transmission direction is from the first port 200 to the second port 201, and then from the second port 201 to the energy conversion device. Since the energy transforming device is sensitive to the external environment, for example, when a head is present outside the energy transforming device, the impedance of the energy transforming device may change, resulting in a change of the reflected energy. According to the principle of the circulator, when the impedance of the energy conversion device changes, a part of energy is reflected from the energy conversion device to the second port 201 and then transmitted from the second port 201 to the third port 202, and then the energy at the third port 202 is changed.
Optionally, the energy harvesting device comprises a coupler for harvesting sample energy of reflected energy of the third port. Specifically, since the energy at the third port 202 changes when the impedance of the energy conversion device changes, and further the energy of the sample of the reflected energy at the third port 202 collected by the coupler changes, it can be determined whether the head is on the energy conversion device by detecting the change of the energy at the third port 202.
Optionally, the coupler comprises a conversion module; the conversion module is used for converting the sample energy into a voltage signal and sending the voltage signal to the processor; the processor is further configured to receive the voltage signal sent by the conversion module, and determine whether the head of the user is located on the energy conversion device according to the voltage signal and a preset calibration value. Fig. 5 provides another schematic diagram of the detection circuit, which is used for representing the whole circuit signal transmission process of the detection circuit. As shown in fig. 5, when the sleep-assisting apparatus is started, the power output port outputs energy, and according to the principle of a circulator, the output energy is transmitted from the first port 200 of the circulator to the second port 201, and is transmitted to the energy conversion device 3 through the second port 201, when the impedance of the energy conversion device 3 changes, reflected energy will be reflected from the end of the energy conversion device 3 to the second port 201, and then transmitted from the second port 201 to the third port 202, and then the reflected energy at the third port 202 is caused to change, so that the sample energy of the reflected energy collected by the coupler changes.
The preset calibration value can be energy of different frequency bands collected when the head of the user leaves the sleep-assisting device. The frequency band is a band consisting of a plurality of frequency points, and a frequency point refers to a specific frequency value, for example, 5.00GH z (gigahertz) is a frequency point in the frequency band of 5.00GHz-5.50 GHz. Optionally, the energy of different frequency bands collected when the head of the user leaves the sleep-assisting device can be collected through the energy collecting device, and the collected energy of different frequency bands is used as a calibration value and stored in a processor of the sleep-assisting device.
Specifically, since the sample energy is generally represented by power, the energy harvesting device cannot directly transmit the power to the processor, and the conversion module in the coupler can convert the sample energy into a voltage signal and transmit the voltage signal to the processor.
In the above embodiment, the detection circuit includes a radio frequency device and an energy harvesting device; the radio frequency device is connected with the energy conversion device, the radio frequency device can receive the reflected energy of the energy conversion device and transmit the reflected energy to the energy acquisition device, then the reflected energy is acquired by the energy acquisition device, and the reflected energy is transmitted to the processor, the processor can judge whether the head of a user is positioned on the energy conversion device according to the reflected energy and a preset calibration value, and further can realize different working states of the energy conversion device according to whether the head of the user is positioned in an energy efficiency area of the sleep-assisting equipment, especially, when the head of the user leaves the working range of the sleep-assisting equipment, the output power of the energy conversion device can be reduced or the energy conversion device is in a closed state, and the purpose of saving resources is achieved.
In one embodiment, as shown in fig. 6, there is provided a method of controlling a sleep-aid device, the method including:

Specifically, the sleep-assisting device can judge whether the head of the user is positioned on the sleep-assisting device according to the reflected energy, and if the head of the user is positioned on the sleep-assisting device according to the judgment result, the output power of the sleep-assisting device can be improved, and the sleep of the user is promoted; if the judgment result is that the head of the user is not on the sleep-assisting device, the output power of the sleep-assisting device can be controlled to be reduced or be in a closing mode. And in the working process of the sleep-assisting equipment, judging whether the head of the user is positioned on the sleep-assisting equipment in real time, and further adjusting the running state of the energy conversion device in real time according to the judgment result.
And S603, controlling the running state of the sleep-assisting equipment according to the judgment result.
Exemplarily, if the head of the user is located on the sleep-assisting device as a result of the determination, the operation state of the sleep-assisting device may be controlled to be in a steady mode; if the judgment result is that the head of the user leaves the sleep-assisting device, the operation state of the sleep-assisting device can be controlled to be in an energy-saving mode.
Specifically, in the working process of the sleep-assisting device, whether the head of the user is positioned on the sleep-assisting device is judged in real time, and then the working mode of the sleep-assisting device is adjusted in real time according to the judgment result.
The control method of the sleep-aiding device provided by the embodiment acquires the reflected energy of the sleep-aiding device; judging whether the head of the user is positioned on the sleep-assisting equipment or not according to the reflected energy to obtain a judgment result; the operating state of the sleep-aiding equipment is controlled according to the judgment result, and different operating states of the sleep-aiding equipment can be operated according to whether the head of the user is located in the energy efficiency area of the sleep-aiding equipment, so that particularly, when the head of the user leaves the operating range of the sleep-aiding equipment, the output power of the energy conversion device can be reduced or the energy conversion device is in a closed state, and the purpose of saving resources is achieved.
On the basis of the foregoing embodiment, as an optional implementation manner, the step S603 of controlling the operation state of the sleep-assisting apparatus according to the determination result includes: if the judgment result shows that the head of the user is positioned on the sleep-assisting device, controlling the sleep-assisting device to continuously output energy; and if the judgment result is that the head of the user leaves the sleep-assisting device, controlling the sleep-assisting device to periodically output energy.
Exemplarily, when the head of the user is positioned on the sleep-assisting device as a result of the judgment, controlling the sleep-assisting device to continuously output energy; when the judgment result shows that the head of the user leaves the sleep-assisting device, the sleep-assisting device can be controlled to output energy periodically every 5 minutes or 10 minutes.

and S701, determining a difference value between the reflected energy and a preset calibration value.
Optionally, the preset calibration value may be energy of different frequency bands collected when the head of the user leaves the sleep-assisting device. The frequency band is a band consisting of a plurality of frequency points, and a frequency point refers to a specific frequency value, for example, 5.00GHz (gigahertz) is one frequency point in the frequency band of 5.00GHz-5.50 GHz. The difference value may be a difference value between the reflected energy and a preset calibration value, or may be an index for measuring the similarity between the reflected energy and the preset calibration value.
Illustratively, the head of the user can be collected by the energy collecting device when leaving the sleep-assisting device, and the collected energy of different frequency bands is taken as a calibration value and stored in the sleep-assisting device; the method comprises the steps of collecting reflection energy of sleep-assisting equipment at regular time, comparing the reflection energy with a preset calibration value stored in the sleep-assisting equipment, and obtaining a difference value between the reflection energy and the preset calibration value.
