All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present application without any creative effort belong to the protection scope of the present application.
The core of the application is to provide a resistor-capacitor energy generator, a method, a device and a medium.
In order that those skilled in the art will better understand the disclosure, the following detailed description will be given with reference to the accompanying drawings.
Fig. 1 is a schematic diagram of a resistance-capacitance energy generator according to an embodiment of the present disclosure. As shown in fig. 1, the resistor-capacitor energy generator includes: a controller 10, a switching power supply circuit 11, a power amplification circuit 12, and an impedance detection circuit 13;
a first input end of the impedance detection circuit 13 is connected with an output end of the power amplification circuit 12, a second input end of the impedance detection circuit 13 is connected with a part to be detected, and an output end of the impedance detection circuit 13 is connected with an input end of the controller 10 and is used for detecting a voltage and current signal of the part to be detected and outputting the voltage and current signal to the controller 10;
the output end of the switching power supply circuit 11 is connected to the first input end of the power amplification circuit 12, and is used for converting the commercial power into a direct-current voltage to supply power to the power amplification circuit 12;
the power amplifying circuit 12 is used for converting the direct-current voltage into a high-frequency current and outputting the high-frequency current to a part to be detected;
a first output end of the controller 10 is connected to the input end of the switching power supply circuit 11, and a second output end of the controller 10 is connected to the second input end of the power amplification circuit 12, and is configured to adjust an output value of a dc voltage of the switching power supply circuit 11 according to the voltage-current signal, and adjust a frequency value of a high-frequency current of the power amplification circuit 12, so as to adjust an energy output power to the portion to be measured.
In specific implementation, the working process of the resistance-capacitance energy generator is as follows: the 220V 50Hz commercial power is processed by the switching power supply circuit 11 to obtain a direct current voltage with the amplitude value regulated by the controller 10, the direct current voltage supplies power to the power amplification circuit 12, the power amplifier generates 300 KHz-1 MHz high-frequency current, and then the high-frequency current acts on biological tissues; the impedance detection circuit 13 detects current and voltage information acting on the biological tissue in real time and supplies the current and voltage information as feedback quantity to the controller 10, and the controller 10 realizes adaptive power output by controlling the amplitude of the switching power supply circuit 11 and the output frequency of the power amplification circuit 12.
It is noted that at the start of operation of the rc generator, the controller 10 is first initialized, giving a DA value that determines the power output. Further, it is necessary to first ascertain the initial impedance value of the biological tissue. Specifically, the controller 10 controls the switching power supply circuit 11 and the power amplification circuit 12 to output a high-frequency test voltage with a peak value of 15V to act on the target tissue, and then the controller 10 obtains an initial impedance value of the target tissue according to the voltage and current information acquired by the impedance detection circuit 13; the controller 10 will then immediately adjust the magnitude of the output voltage of the switching power supply circuit 11 to achieve the effect of setting the output power value based on the initial impedance value and the set power value (DA value).
Further, the impedance range of the human skin is 50 Ω to 1500 Ω. The controller 10 first determines whether the impedance value of the biological tissue is within this range. If yes, adaptive output power adjustment is needed. Specifically, the rated load (the impedance value corresponding to the maximum output power) is 500 Ω, and the impedance range of the skin of the human body is adjusted in two sections according to the rated load:
the first section is 50 omega-500 omega, wherein, the output power is 50% of the output power when the output power is 500 omega when the output power is 50 omega, the output power is gradually increased from 50 omega to 500 omega, and the output power is maximum when the output power is 500 omega; when the maximum output power is set to 100W (the set power range is 1 to 100W), the power impedance curve formula P = (1/9) × R +400/9. And when the human body impedance value falls in the first section, acquiring the output power at the moment through the power impedance curve formula.
The second section is 500 omega-1500 omega, wherein the 500 omega output power is the maximum, 50% of the output power when the 1500 omega output power is 500 omega, and the power output is gradually reduced from 500 omega to 1500 omega; when the maximum output power is set to be 100W, the rate-impedance curve formula is P = (-1/20) × R +125. And when the human body impedance value falls in the second section, acquiring the output power at the moment through the power impedance curve formula.
Specifically, in order to adjust the output power to the power corresponding to the human body impedance value at this time, the actual output power value is first compared with the calculated power value obtained by the power impedance curve formula, so as to obtain a difference Δ P between the actual power value and the calculated power value. When 0< Δ P < =1, the DA value of the controller 10 is decreased by 1; when-1 < Δ P < =0, the DA value of the controller 10 is increased by 1; when 1< Δ P < =5, the DA value of the controller 10 is decreased by 5; when-5 < Δ P < = -1, the DA value of the controller 10 is increased by 5; when Δ P >5, the DA value of controller 10 is decremented by 10; when Δ P < -5, the DA value of the controller 10 is increased by 10.
It should be noted that the addition and subtraction time of DA is 1ms, and the actual power value is infinitely close to the calculated power value through the adjustment of the output power, so as to achieve the adaptive power output.

Fig. 7 is a flowchart of a method for generating rc energy according to an embodiment of the present disclosure. The method is applied to a resistance-capacitance energy generator comprising a controller 10, a switching power supply circuit 11, a power amplification circuit 12 and an impedance detection circuit 13; as shown in fig. 7, the method includes:
s10: and acquiring a voltage and current signal of the part to be detected acquired by the impedance detection circuit.
S11: and adjusting the output value of the direct current voltage of the switching power supply circuit according to the voltage and current signal, and adjusting the frequency value of the high-frequency current of the power amplification circuit so as to adjust the energy output power of the part to be detected.
In a specific implementation, the controller 10 is first initialized, given a DA value that determines the power output. Further, the initial impedance value of the biological tissue at the site to be measured needs to be ascertained first. Specifically, the controller 10 controls the switching power supply circuit 11 and the power amplification circuit 12 to output a high-frequency test voltage with a peak value of 15V to act on the target tissue, and then the controller 10 obtains an initial impedance value of the target tissue according to the voltage and current information acquired by the impedance detection circuit 13; the controller 10 will then immediately adjust the magnitude of the output voltage of the switching power supply circuit 11 to achieve the effect of setting the output power value based on the initial impedance value and the set power value (DA value).
Further, the impedance range of the human skin is 50 Ω to 1500 Ω. The controller 10 first determines whether the impedance value of the biological tissue is within this range. If yes, adaptive output power adjustment is needed. Specifically, the rated load (the impedance value corresponding to the maximum output power) is 500 Ω, and the impedance range of the skin of the human body is adjusted in two sections according to the rated load:
the first section is 50 omega-500 omega, wherein the output power at 50 omega is 50% of the output power at 500 omega, the output power is gradually increased from 50 omega to 500 omega, and the output power is maximum at 500 omega; when the maximum output power is set to 100W (the set power range is 1 to 100W), the power impedance curve formula P = (1/9) × R +400/9. And when the human body impedance value falls in the first section, acquiring the output power at the moment through the power impedance curve formula.
The second section is 500 omega-1500 omega, wherein the 500 omega output power is the maximum, 50% of the output power when the 1500 omega output power is 500 omega, and the power output is gradually reduced from 500 omega to 1500 omega; when the maximum output power is set to be 100W, the rate-impedance curve formula is P = (-1/20) × R +125. And when the human body impedance value falls in the second section, acquiring the output power at the moment through the power impedance curve formula.
Specifically, in order to adjust the output power to the power corresponding to the human body impedance value at this time, the actual output power value is first compared with the calculated power value obtained by the power impedance curve formula, so as to obtain a difference Δ P between the actual power value and the calculated power value. When 0< Δ P < =1, the DA value of the controller 10 is subtracted by 1; when-1 < Δ P < =0, the DA value of the controller 10 is increased by 1; when 1< Δ P < =5, the DA value of the controller 10 is decreased by 5; when-5 < Δ P < = -1, the DA value of the controller 10 is increased by 5; when Δ P >5, the DA value of controller 10 is decremented by 10; when Δ P < -5, the DA value of the controller 10 is increased by 10.
It should be noted that the addition and subtraction time of DA is 1ms, and the actual power value is infinitely close to the calculated power value through the adjustment of the output power, so as to achieve the adaptive power output. When the impedance of the skin of the human body is less than 50 Ω or greater than 1000 Ω, the DA value of the controller 10 is continuously reduced to 0, the output voltage of the switching power supply circuit 11 is 0, and the resistance-capacitance energy generator does not output energy at this time.
In this embodiment, the voltage and current signals of the portion to be measured acquired by the impedance detection circuit are obtained. And adjusting the output value of the direct current voltage of the switching power supply circuit according to the voltage and current signal, and adjusting the frequency value of the high-frequency current of the power amplification circuit so as to adjust the energy output power of the part to be detected. According to the scheme, the output frequency and the output voltage of the power amplifier are adjusted according to the voltage and current signals of the part to be detected and the specific voltage and current signals of the part to be detected, so that the corresponding output power can be adjusted and output according to different impedances of human skin, and the optimal treatment effect is achieved.
