It will be apparent that the described embodiments are only some, but not all, embodiments of the application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
The following describes in detail the technical solutions provided by the embodiments of the present application with reference to the accompanying drawings.
The embodiment of the application provides a control method of an electronic mask, as shown in fig. 1, and provides a flow chart of the control method of the electronic mask, wherein the control method of the electronic mask is executed by wearable equipment, and the control method of the electronic mask at least comprises the following steps S110 to S140:
step S110, under the condition that the wearable device is connected with the electronic mask and the electronic mask is used for introducing essence, acquiring an electric signal of the essence detected by the detection electrode pair on the electronic mask.
The control method of the electronic mask in the embodiment of the application is executed by a wearable device which is designed independently, wherein the wearable device can be regarded as an intelligent central control platform for adapting the electronic mask and other various types of beauty care devices, and the intelligent central control platform can be designed into different forms according to actual requirements, for example, any form of hair clasp, hair clip and the like which can be fixedly worn on the head of a user can be adopted. The electronic mask is designed to be in a wearable form, on one hand, the habit of using the electronic mask to perform facial skin care is considered, for example, the user can be assisted to finish hair before using the electronic mask through the wearable device in a hair band shape, and further the user can perform subsequent skin care operation conveniently. On the other hand, the wearable device is convenient for exerting various functions when being matched with other various types of beauty care devices.
The wearable device provided by the embodiment of the application can be electrically connected with the electronic mask, and the mask cloth of the electronic mask is provided with at least one pair of conductive silver paste electrodes, namely a detection electrode pair, for detecting the electric signals. When a user prepares to use the electronic mask for skin care, the used essence is required to be led into mask cloth of the electronic mask, and the conductive silver paste electrode on the mask cloth is soaked by the essence, so that the surface of the mask cloth presents conductivity due to the fact that the essence contains conductive ions.
The wearable device can control and output a sine wave excitation signal with fixed frequency to act on the conductive silver paste electrode, the excitation signal is subjected to partial pressure in a circuit through essence on the conductive silver paste electrode, an electric signal is generated, and the electric signal is transmitted to the wearable device for subsequent processing through an electric connection relation between the electronic mask and the wearable device.
And step S120, measuring the electric signals of the essence to obtain a voltage measurement value and a current measurement value.
After the electric signals of the essence detected by the detection electrode pair are obtained, the electric signals of the essence are required to be subjected to voltage and current measurement and converted into analog signals which can be directly measured by the wearable equipment, and a voltage measurement value and a current measurement value are obtained.
And step S130, processing the voltage measured value and the current measured value to obtain characteristic parameters of the essence, and determining the type of the essence and the permeation promotion current corresponding to the type of the essence according to the characteristic parameters of the essence and a preset essence characteristic parameter database.
After the voltage measurement value and the current measurement value are measured, further processing and calculation are needed to obtain the characteristic parameters of the essence, wherein the characteristic parameters can comprise impedance amplitude values based on the physical relationship between the voltage and the current, and can be obtained according to the amplitude values of the voltage and the current.
Because the conductivity of different essences is different, the embodiment of the application can identify the type of the essence and the corresponding permeation promotion current used by a user by calculating the characteristic parameters related to the conductivity of the essence and using the characteristic parameters as the basis for identifying the type of the essence and further combining with a pre-established essence characteristic parameter database. The essence characteristic parameter database is mainly used for storing characteristic parameters of standards corresponding to different types of essences and corresponding permeation promotion current.
And step S140, controlling the electronic mask to output permeation promotion current corresponding to the essence type.
After the essence type and the corresponding permeation promotion current are determined, a control instruction can be sent to the electronic mask to control the electronic mask to output the permeation promotion current with the corresponding size, so that intelligent identification of the essence type and intelligent control of the permeation promotion current are realized.
According to the embodiment of the application, the wearable device and the electronic mask are arranged independently to be matched with each other, the characteristic parameter data of the essence on the electronic mask is analyzed, and the type of the essence infiltrated on the electronic mask is identified based on the characteristic parameter database corresponding to the type of the essence constructed in advance, so that the intelligent control of the output permeation promotion current of the electronic mask is realized, the manual operation of a user is not needed, and the skin care experience of the user is improved.
In some embodiments of the present application, the measuring the electrical signal of the essence to obtain a voltage measurement value and a current measurement value includes: performing voltage measurement on the electric signal of the essence through a differential amplifier to obtain a voltage measurement value; and carrying out current measurement on the electric signal of the essence through a current amplifier to obtain the current measurement value.
The measurement of the electric signal of the essence mainly comprises voltage measurement and current measurement, and for the voltage measurement, the electric signal can be measured by utilizing a differential amplifier to obtain a voltage measurement value. A differential amplifier is a circuit capable of amplifying the difference between two input voltages, and is also called a differential amplifier, which can be balanced input and output, or single-ended (unbalanced) input and output, and is commonly used for realizing the mutual conversion of a balanced circuit and an unbalanced circuit, and is a basic unit of various integrated circuits.
For current measurement, the electrical signal may be measured with a current amplifier to obtain a current measurement. A current amplifier is a circuit for increasing the current amplitude of an input signal by a preset signal, in short, an amplifier that makes a given input current higher, and is also a basic unit of various integrated circuits.
In some embodiments of the present application, the characteristic parameters of the essence include a resistance value of the essence, and the processing the voltage measurement value and the current measurement value to obtain the characteristic parameters of the essence includes: performing discrete Fourier transform operation on the voltage measured value and the current measured value respectively to obtain a voltage amplitude and a current amplitude; determining the impedance amplitude of the essence according to the voltage amplitude and the current amplitude; determining the resistance value of the essence according to the impedance amplitude of the essence; and determining the type of the essence according to the resistance value of the essence and the preset essence characteristic parameter database.
The characteristic parameters of the essence of the embodiment of the application mainly comprise the resistance value of the essence, the resistance value can be extracted from the impedance amplitude of the essence of the circuit, the impedance amplitude refers to the amplitude of the impedance value, and the impedance is the blocking effect on alternating current in the circuit with resistance, inductance and capacitance. The resistance value of the essence has a relation with the conductivity of the essence, so that the embodiment of the application can identify the type of the essence by calculating the resistance value of the essence.
The magnitude of the impedance of the essence can be calculated based on the voltage measurement value and the current measurement value, and since the voltage measurement value measured by the differential amplifier and the current measurement value measured by the current amplifier are Analog signals, the voltage measurement value and the current measurement value can be converted into digital signals for calculation by an ADC (Analog-to-Digital Converter).
Since the alternating current is applied to the electronic mask, the embodiment directly measures the real part and the imaginary part of the voltage and the real part and the imaginary part of the current, the voltage amplitude U can be calculated according to the real part and the imaginary part of the voltage, the current amplitude I can be calculated according to the real part and the imaginary part of the current, the impedance amplitude z=u/I can be obtained according to the physical relationship between the voltage and the current, and the resistance value R of the essence can be further extracted from the impedance amplitude Z due to the fact that the resistor, the capacitor and the inductor are possibly involved in the circuit, and then the type of the essence is determined according to the extracted resistance value R of the essence and a preset essence characteristic parameter database.
In some embodiments of the present application, the characteristic parameters of the essence include a resistance value of the essence, and determining the type of the essence and the permeation promotion current corresponding to the type of the essence according to the characteristic parameters of the essence and a preset essence characteristic parameter database includes: determining the conductivity corresponding to the resistance value of the essence according to the corresponding relation between the resistance value and the conductivity; and determining the type of the essence according to the conductivity corresponding to the resistance value of the essence and the preset essence characteristic parameter database.
The embodiment of the application can evaluate the conductivity of the essence by using the conductivity sigma, wherein the conductivity sigma is a parameter for describing the difficulty of electric charge flow in a substance, and the conductivity is worse as the conductivity is higher.
Since the physical correspondence between the resistance R and the conductance G is known, namely:
G＝1/R， (1)
while the physical correspondence between conductance and conductivity is also known, namely:
σ＝G*L/A， (2)
in the embodiment of the application, L may represent the distance between two electrodes in the detection electrode pair, and a may represent the cross-sectional area of the electrodes, which are all known parameters.
Therefore, the correspondence between the resistance Rn and the conductivity σn of the embodiment of the present application can be obtained based on the above equations (1) and (2), that is:
σn＝L/(Rn*A)， (3)
Based on the formula (3), the resistance value R of the currently calculated essence is brought in, so that the corresponding conductivity sigma can be obtained, and as the preset essence characteristic parameter database stores the conductivity parameters of the standards corresponding to various types of essences, the type of the essence corresponding to the conductivity sigma can be determined by comparing the currently calculated conductivity sigma with the conductivity parameters of the standards corresponding to various types of essences in the database.
It should be noted that, considering that the user may start to trigger the process of identifying the essence after wearing the electronic mask, since the electronic mask is already in contact with the skin of the user, the skin impedance of the user and the impedance of the mask cloth may affect the calculation of the resistance value of the essence, and thus when comparing the currently calculated conductivity σn with the standard conductivity in the database, the conductivity values are not required to be completely equal, that is, the deviation between the conductivity σn and the standard conductivity is less than a certain deviation threshold.
Of course, the user can be reminded to start the electronic mask and the wearable device before wearing, namely, the identification of the essence type is completed before wearing, and the influence of the existence of skin impedance of the user on the calculation of the resistance value of the essence is avoided.
In some embodiments of the present application, the characteristic parameters of the essence include a resistance value of the essence, and determining the type of the essence and the permeation promotion current corresponding to the type of the essence according to the characteristic parameters of the essence and a preset essence characteristic parameter database includes: obtaining corresponding relations among a plurality of essence types, impedance error compensation coefficients and standard conductivities from the preset essence characteristic parameter database; according to the resistance value of the essence, the corresponding relation between the types of the plurality of essences and the impedance error compensation coefficient and the standard conductivity and the corresponding relation between the resistance value and the conductivity, determining candidate conductivities corresponding to the impedance error compensation coefficients; and determining the final essence type and the permeation promotion current corresponding to the essence type according to the candidate conductivity and the standard conductivity corresponding to each impedance error compensation coefficient.
As described above, if the type of the essence is identified before the user wears the electronic mask, the existence of the skin impedance of the user does not affect the calculation of the resistance value of the essence, but the existence of the impedance of the mask cloth itself affects the calculation of the resistance value of the essence.
According to the embodiment of the application, the impedance errors corresponding to various types of essences can be tested in advance, through various types of essence tests, the impedance of the resistor of each type of essence has an error value with a certain linear relation, the impedance error compensation coefficient corresponding to each type of essence can be obtained through linear fitting, and the impedance error compensation coefficient can be used for representing the error existing in the resistance value of the essence obtained based on the embodiment, wherein the error is mainly caused by the existence of the impedance of the mask cloth. Assuming 1, 2, 3 … … n essences are provided, the corresponding impedance error compensation coefficients can be denoted as K1, K2, K3 … … Kn, respectively.
Based on the equation (3) in the foregoing embodiment, the resistance R in the equation (3) may be compensated with an impedance error compensation coefficient, which may be expressed specifically as follows:
σn＝L/(Kn*Rn*A)， (3)
since the types of the essences are not determined at present, kn is unknown, but impedance error compensation coefficients Kn corresponding to different essence types n and corresponding standard conductivities sigma n can be stored in advance in a preset essence characteristic parameter database, and since the types of the essences are limited and the number of the essences is not large, K1, K2 and K3 … … Kn can be brought into the formula (3) one by one, so that corresponding candidate conductivities sigma 1', sigma 2', sigma 3'… … sigma n' can be obtained respectively.
Further, the correspondence stored in the preset essence characteristic parameter database of the present application may be expressed in the form of the following table 1:
TABLE 1
| Essence type n | Standard conductivity sigma | Current I for promoting permeation | Impedance error compensation coefficient K |
| 1 | σ1 | I1 | K1 |
| 2 | σ2 | I2 | K2 |
| …… | …… | …… | …… |
| n | σn | In | Kn |
Based on the above table 1, the standard conductivities corresponding to K1, K2, K3 … … Kn can be determined, so that the final essence type and the penetration promoting current corresponding to the essence type are determined according to the comparison result by comparing the currently obtained candidate conductivities σ1', σ2', σ3'… … σn' with the standard conductivities σ1, σ2, σ3 … … σn corresponding to the database, respectively.
In some embodiments of the present application, the determining the final essence type and the permeation promotion current corresponding to the essence type according to the candidate conductivity and the standard conductivity corresponding to each impedance error compensation coefficient includes: respectively determining the deviation between the candidate conductivity corresponding to each impedance error compensation coefficient and the standard conductivity; and under the condition that the deviation between the candidate conductivity and the standard conductivity corresponding to any one impedance error compensation coefficient is smaller than a preset deviation threshold, determining the essence type corresponding to the impedance error compensation coefficient as a final essence type, and obtaining the permeation promotion current corresponding to the essence type.
When comparing each candidate conductivity with the corresponding standard conductivity, if the conductivity deviation between the candidate conductivities is smaller than a certain threshold value, the candidate conductivities are considered to be the same essence type, namely the essence type corresponding to the standard conductivity is regarded as the final essence type.
For example, assuming that the standard conductivity of the whitening essence 1 is 4000, the standard conductivity of the anti-aging essence 2 is 3000, the standard conductivity of the water replenishing essence 3 is 2000, and after K1 is brought into the above formula (3), the calculated candidate conductivity σ1' is equal to 4000, the current essence type is considered to be the whitening essence, so that the penetration promoting current corresponding to the whitening essence is obtained according to the corresponding relation stored in the database.
In some embodiments of the present application, after determining the type of the essence and the permeation promotion current corresponding to the type of the essence according to the feature parameters of the essence and the preset essence feature parameter database, the method further includes: generating terminal display data according to the essence type and the permeation promotion current corresponding to the essence type; and sending the terminal display data to a terminal device so that the terminal device displays the terminal display data.
In order to further improve skin care experience of a user, the embodiment of the application can also provide a terminal data display function, namely, based on wireless communication connection established between the wearable device and the terminal device, the data such as the type of the essence and the corresponding permeation promotion current which are recognized at present are sent to the terminal device for display, so that the user can intuitively know related skin care data, and the skin care experience is improved.

The control flow of the electronic mask provided by the embodiment of the application is mainly realized based on interaction between the electronic mask and the wearable equipment. Firstly, when a user prepares to use an electronic mask for skin care, the used essence is required to be led into mask cloth of the electronic mask, a detection electrode pair on the mask cloth is soaked by the essence, then a wearable device controls and outputs a sine wave excitation signal with fixed frequency to act on a conductive silver paste electrode, the excitation signal is subjected to voltage division in a circuit through the essence on the conductive silver paste electrode, an electric signal is generated, and the electric signal is transmitted to the wearable device for processing through an electric connection relation between the electronic mask and the wearable device.
