It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
The method for determining the sleep-aiding area provided by the application can be applied to the application environment shown in fig. 1. Wherein the sleep aid device 101 is contactable with the human head 102. The sleep-assisting apparatus 101 may be an apparatus for assisting sleep only or an apparatus for assisting sleep having a sleep monitoring function. Sleep-aiding equipment such as sleep-aiding pillow. Specifically, the sleep-aiding device 101 can respectively control a plurality of electromagnetic wave emitting units included in the device, so that each electromagnetic wave emitting unit sequentially emits electromagnetic waves to the human head 102 according to a plurality of preset frequency points in a preset frequency band, collects the emitting power and the reflected power of the electromagnetic waves emitted by each electromagnetic wave emitting unit at each preset frequency point, and calculates the differential power of each electromagnetic wave emitting unit at each preset frequency point according to the emitting power and the reflected power; selecting a preset frequency point corresponding to the minimum difference power in the difference powers as a target frequency point; and determining a sleep-aiding area according to the difference power corresponding to the target frequency point and the position parameters of the electromagnetic wave transmitting units. The sleep-aid area is available for the sleep-aid device 101 to perform sleep-aid operations.
In one embodiment, as shown in fig. 2, a method for determining a sleep-aid area is provided, which is described by taking the method as an example of being applied to the sleep-aid device in fig. 1, and comprises the following steps:
step S202, a plurality of electromagnetic wave emission units of the sleep-aiding device are respectively controlled, so that each electromagnetic wave emission unit sequentially emits electromagnetic waves according to a plurality of preset frequency points in a preset frequency band.
Wherein, the electromagnetic wave transmitting unit refers to an antenna or an antenna array used for transmitting electromagnetic waves in the sleep-assisting equipment. A frequency band is a segment 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 a frequency band of 5.00GHz to 5.50 GHz.
In particular, the sleep aid device may be provided with a switch for activating the sleep aid device. The switch is such as touch-sensitive switch or entity button, and entity button can be by button, action contact, reset spring and button box composition. When the sleep-assisting equipment receives a starting instruction triggered by the switch, the sleep-assisting equipment is started according to the starting instruction, and the original electromagnetic wave transmitting units in the sleep-assisting equipment are respectively controlled, so that each electromagnetic wave transmitting unit sequentially transmits electromagnetic waves according to a plurality of preset frequency points in a preset frequency band.
Take the example of being provided with touch-sensitive switch on helping the dormancy equipment, this touch-sensitive switch can set up in helping the upper surface of dormancy equipment, and when this touch-sensitive switch was touched to people's head, this helped the dormancy equipment of start. Respectively controlling a plurality of electromagnetic wave emission units in the sleep-aiding equipment, so that each electromagnetic wave emission unit emits electromagnetic waves sequentially according to a plurality of preset frequency points in a preset frequency band.
Furthermore, the sleep-aiding device can be preset with interval values among the frequency points in the preset frequency band, and the frequency points in the preset frequency band can be determined according to the interval values. Taking the preset frequency band of 5.15GHz-5.35GHz and the frequency point interval of 2MHz (megahertz) as an example, the total interval between the frequency bands of 5.15GHz-5.35GHz is 200MHz, 100 frequency points between the frequency bands of 5.15GHz-5.35GHz can be calculated according to the frequency point interval of 2MHz, wherein the frequency points are 5.15GHz, 5.17GHz and 5.19GHz … … 5.35.35 GHz, and a plurality of electromagnetic wave transmitting units in the sleep-aid device are respectively controlled, so that each electromagnetic wave transmitting unit sequentially transmits electromagnetic waves according to the 100 frequency points.
Step S204, collecting the transmitting power and the reflected power of the electromagnetic waves transmitted by each electromagnetic wave transmitting unit at each preset frequency point.
Wherein, the transmission power refers to the energy consumed by transmitting the electromagnetic wave, and the unit is power (W) or gain (dBm). Reflected power refers to the unabsorbed power in the transmitted power, in units of power (W) or gain (dBm).
Specifically, since each electromagnetic wave transmitting unit transmits electromagnetic waves at each frequency point in the preset frequency band, each electromagnetic wave transmitting unit generates transmitting power and reflecting power at each frequency point in the preset frequency band, and the transmitting power and the reflecting power generated when each electromagnetic wave transmitting unit transmits electromagnetic waves at each preset frequency point can be collected. For example, 50 frequency points exist in a preset frequency band, each electromagnetic wave transmitting unit generates 50 transmitting powers and 50 reflecting powers, and 50 transmitting powers and 50 reflecting powers of each electromagnetic wave transmitting unit can be collected.
And step S206, calculating the difference power of each electromagnetic wave transmitting unit at each preset frequency point according to the transmitting power and the reflected power.
Wherein the difference power is a difference between the transmitted power and the reflected power. Specifically, the difference power of each electromagnetic wave transmitting unit at each preset frequency point is calculated according to the transmitting power and the reflected power of each electromagnetic wave transmitting unit at each preset frequency point. It can be understood that the number of the difference powers of each electromagnetic wave emitting unit is the same as the number of the corresponding emitting power and the corresponding reflected power, for example, 30 emitting powers and 30 reflected powers of each electromagnetic wave emitting unit are collected, and then 30 difference powers of each electromagnetic wave emitting unit can be calculated.
Step S208, selecting a preset frequency point corresponding to the minimum difference power in the difference powers as a target frequency point.
Specifically, the smaller the difference power is, the closer the difference power is to the head of the person, the larger the difference power is, the farther the difference power is from the head of the person, and then, among all the difference powers obtained through calculation, the preset frequency point corresponding to the minimum difference power is selected as the target frequency point. Taking 10 electromagnetic wave transmitting units and 20 frequency points in a preset frequency band as an example, each electromagnetic wave transmitting unit obtained through calculation has 20 difference powers, and then 20 × 10 is 200 difference powers, it can be understood that each difference power has a corresponding preset frequency point, and in the 200 difference powers, the preset frequency point corresponding to the minimum difference power is selected as a target frequency point.
Step S210, determining a sleep-aiding area according to the difference power corresponding to the target frequency point and the position parameters of the electromagnetic wave emission units.
Wherein, the position parameter refers to the position parameter of the electromagnetic wave emission unit on the sleep-assisting equipment. The sleep aid area refers to the area of the human head that is represented by the outline of the head that acts on the sleep aid device.
Specifically, the smaller the differential power of the electromagnetic wave emission unit at the target frequency point is, the closer the electromagnetic wave emission unit is to the head of the person is, and the distance between each electromagnetic wave emission unit and the head of the person can be represented by the differential power of each electromagnetic wave emission unit at the target frequency point. According to the distance between each electromagnetic wave emitting unit and the head of the person and the position parameters of the electromagnetic wave emitting units on the sleep-assisting device, the head outline of the head of the person acting on the sleep-assisting device can be determined, and the area represented by the head outline can be determined as the sleep-assisting area.
In the method for determining the effective sleep-aiding area, each electromagnetic wave transmitting unit is enabled to transmit electromagnetic waves according to a plurality of preset frequency points in a preset frequency band in sequence, the difference power of each electromagnetic wave transmitting unit at each preset frequency point is calculated, the smaller the difference power is, the closer the electromagnetic wave transmitting unit is to the head of a person is, and therefore the frequency point corresponding to the minimum difference power in the difference power is used as the target frequency point. The difference power of the plurality of electromagnetic wave emission units at the target frequency point is determined, then the head outline of the head acting on the sleep-aiding equipment can be accurately obtained according to the difference power of the plurality of electromagnetic wave emission units corresponding to the target frequency point and the position parameters of the electromagnetic wave emission units, the area represented by the head outline is used as the sleep-aiding area, and the accuracy is high.
In one embodiment, respectively controlling a plurality of electromagnetic wave emission units of the sleep-aiding device, so that each electromagnetic wave emission unit sequentially emits electromagnetic waves according to a plurality of preset frequency points in a preset frequency band comprises: collecting induction values of a plurality of sensors of the sleep-assisting equipment; screening induction values exceeding a preset induction threshold value from the collected induction values; determining an emission area according to the position parameters of the sensor corresponding to the screened induction values; and respectively controlling the plurality of electromagnetic wave transmitting units in the transmitting area, so that each electromagnetic wave transmitting unit in the transmitting area sequentially transmits electromagnetic waves according to a plurality of preset frequency points in a preset frequency band.
The sensor is a detection device, such as a pressure sensor or a temperature sensor, capable of converting sensed detection information into an electric signal or outputting information in other required forms according to a preset rule.
Specifically, the sleep-assisting device can be provided with a plurality of sensors for monitoring the induction value generated by the head of the person acting on the sensors. After the sleep-assisting equipment is started, the induction value monitored by each sensor of the sleep-assisting equipment is collected, the larger the induction value is, the closer the representative is to the head of a person, the smaller the induction value is, and the farther the representative is from the head of the person. The induction values exceeding a preset induction threshold value can be screened from the induction values of the plurality of inductors, the position parameters of the sensor on the sleep-assisting equipment corresponding to the screened induction values are determined, the approximate region of the head of the person on the sleep-assisting equipment can be preliminarily determined according to the position parameters, and the region is used as an emission region.
After the emission area is determined, a plurality of electromagnetic wave emission units contained in the emission area are respectively controlled, so that each electromagnetic wave emission unit in the emission area sequentially emits electromagnetic waves according to a plurality of preset frequency points in a preset frequency band. It can be understood that the sensors may be disposed at the same positions on the sleep-aid device in one-to-one correspondence with the electromagnetic wave emitting units, or may be disposed at different positions on the sleep-aid device respectively with the electromagnetic wave emitting units.
In this embodiment, the region of the sleep-assisting device far from the head of the person is excluded according to the preset sensing threshold, the approximate region of the head of the person in the sleep-assisting device is preliminarily determined, the region is used as the emission region, the sleep-assisting region is determined only according to the electromagnetic wave emission unit in the emission region, and the efficiency is high.
In one embodiment, calculating the differential power of each electromagnetic wave transmitting unit at each preset frequency point according to the transmitting power and the reflected power comprises: determining a transmitting power curve of each electromagnetic wave transmitting unit according to the transmitting power of the electromagnetic waves transmitted at each preset frequency point; determining a reflected power curve of each electromagnetic wave transmitting unit according to the reflected power of the electromagnetic wave transmitted at each preset frequency point; calculating a difference power curve of each electromagnetic wave transmitting unit according to the transmitting power curve and the reflection power curve of each electromagnetic wave transmitting unit; selecting a preset frequency point corresponding to the minimum difference power in the difference powers as a target frequency point comprises the following steps: and selecting a preset frequency point corresponding to the minimum difference power in the difference powers represented by the difference power curve as a target frequency point.
Specifically, a transmission power curve of each electromagnetic wave transmitting unit is drawn according to the transmission power of each electromagnetic wave transmitting unit at each preset frequency point of a preset frequency band, and a reflection power curve of each electromagnetic wave transmitting unit is drawn according to the reflection power of each electromagnetic wave transmitting unit at each preset frequency point of the preset frequency band. And drawing a difference power curve of each electromagnetic wave transmitting unit according to the transmitting power curve and the reflected power curve of each electromagnetic wave transmitting unit. And selecting a preset frequency point corresponding to the minimum difference power in the difference powers represented by all the difference power curves as a target frequency point.
Taking the number of frequency points in the preset frequency band as 10 and the number of the electromagnetic wave transmitting units as 10 as an example, the transmitting power curve, the reflecting power curve and the difference power curve of each electromagnetic wave transmitting unit at each preset frequency point in the preset frequency band are 10, and each transmitting power curve, each reflecting power curve and each difference power curve respectively represent the transmitting power, the reflecting power and the difference power of the corresponding electromagnetic wave transmitting unit at the 10 frequency points.

In particular, an origin point may be determined on the sleep-aid device, such as the center of the sleep-aid device, in a random or pre-set manner. The two-dimensional coordinates of the electromagnetic wave emitting units on the sleep-aiding equipment are determined according to the original point, the two-dimensional coordinates of the electromagnetic wave emitting units on the sleep-aiding equipment can be represented by the parameter values of the electromagnetic wave emitting units on the X axis and the Y axis, the magnitude of the differential power of the target frequency point can be represented by the parameter value of the electromagnetic wave emitting unit on the Z axis, the magnitude of the differential power can be converted, and the height of the head from the sleep-aiding equipment can be represented. According to X, Y and the Z axis, a three-dimensional coordinate graph is obtained, the graph of the three-dimensional coordinate graph is that the head of a person acts on the head outline of the sleep-assisting device, and the area represented by the head outline is used as the sleep-assisting area. In the embodiment, the efficiency of determining the sleep-aiding area according to the three-dimensional coordinate graph is higher.

Specifically, as the difference power is smaller, the closer the head of the person is to the sleep-assisting device, the larger the difference power is, and the farther the head of the person is from the sleep-assisting device, the difference power corresponding to the target frequency point of the plurality of electromagnetic wave transmitting units can be divided into two parts according to the difference power threshold. Electromagnetic wave emitting units corresponding to the difference power less than or equal to the difference power threshold may be determined as electromagnetic wave emitting units associated with the sleep-aid area, and electromagnetic wave emitting units corresponding to the difference power greater than the difference power threshold may be determined as electromagnetic wave emitting units not associated with the sleep-aid area.
