Described control system comprises microcomputer controlling module and automatic frequency tuning module, and the automatic frequency tuning module comprises phase-locked loop module, output module and the matching detection A/D modular converter of stabilized frequency; The frequency signal with certain Changing Pattern of described microcomputer controlling module in phase-locked loop module is provided at the frequency range of setting, provide stable frequency signal to output module after the phase-locked loop module frequency stabilization, output module is exported the signal of telecommunication to transducer, transducer is converted into mechanical energy with electric energy, and the energy back that reflects when ultrasound wave run into the different medium interface is transformed into the signal of telecommunication, described matching detection A/D modular converter is sampled to the electric current of output module and is delivered to microcomputer controlling module note after A/D conversion, when changing in the frequency range that frequency signal Fr is setting according to certain rules, microcomputer controlling module is noted the working current value in the whole frequency range, after whole frequency range search is finished, microcomputer controlling module calculates the frequency parameter under the corresponding maximum operating currenbt, and control is followed the tracks of in this Frequency point.
Between described phase-locked loop module and output module, also be provided with the excitation amplification module, before output, signal is amplified.
Described frequency change rule is that every change one secondary frequencies increases or reduce 500HZ.
After having adopted technique scheme,, can adjust the sound head temperature to be suitable for human body temperature by regulating the working time owing to increased temperature detecting module.Thereby the sound head that has solved existing supersonic face care Body beautifying instrument is can Yin Wendu behind the do-nothing operation state too high and can make the people feel the technical problem of serious discomfort when contact with human body.In addition, owing to adopted the automatic frequency tuning technology, make sound head when work, can choose best frequency, to reach best physiotheraping effect according to different tissues.
Description of drawings
Fig. 1 is the theory structure sketch map of control system of the present invention.
The specific embodiment
In the ultrasonic propagation process, when running into different medium interfaces, can produce reflection, and this reflected energy becomes the signal of telecommunication after the transducer reciprocal transformation.After the dedicated test electric circuit inspection, change parameter of oscillation, seek best frequency of oscillation and matching status, thereby realize the optimum matching of sound head and people's body medium, the operation principle of Here it is this intelligent sound head.
The present invention has adopted following technology: control of little (MCU) computer and detection technique, automatic frequency tuning (AFT) technology, the PHASE-LOCKED LOOP PLL TECHNIQUE of variant (PLL), and automatic temperature-adjusting control (ATC) technology.
A kind of as shown in Figure 1 sound head of supersonic face care Body beautifying instrument, comprise shell, control system and transducer, control system comprises microcomputer controlling module MCU, automatic frequency tuning modules A FT and temperature control modules ATC, and automatic frequency tuning modules A FT comprises phase-locked loop module PLL, output module and the matching detection A/D modular converter of stabilized frequency; The reference frequency signal Fr with certain Changing Pattern of microcomputer controlling module MCU in phase-locked loop module PLL is provided at the frequency range of setting, provide stable frequency signal Fvco to output module after the phase-locked loop module PLL frequency stabilization, output module is exported the signal of telecommunication to transducer, transducer is converted into mechanical energy with electric energy, and the energy back that reflects when ultrasound wave run into the different medium interface is transformed into the signal of telecommunication, matching detection A/D modular converter is sampled to the electric current of output module and is delivered to microcomputer controlling module MCU note after A/D conversion, when changing in the frequency range that frequency signal Fvco is setting according to certain rules, microcomputer controlling module MCU notes the working current value in the whole frequency range, after whole frequency range search is finished, microcomputer controlling module MCU calculates the frequency parameter under the corresponding maximum operating currenbt, and control PLL follows the tracks of in this Frequency point, between phase-locked loop module PLL and output module, also be provided with the excitation amplification module, before output, signal is amplified, temperature control modules comprises temperature detection and thresholding comparison module, microcomputer controlling module MCU regularly detects and compares by thresholding comparison module and fiducial temperature the temperature of shell by temperature detecting module, and controls sound head work pulse duration ratio in view of the above.Its operation principle is summarized as follows:
When start powers on, MCU controls PLL, in the frequency range of setting, search for 500HZ stepping frequency conversion, frequency step of every change, promptly detect the output stage operating current, when transducer and transmission medium reach optimum matching, this moment, reflected energy was less, the operating current maximum, rather than during best match frequency, reflect bigger, operating current is less, thus the output stage operating current reflected transducer under different frequencies with the matching state of medium, this operating current sampled, deliver to MCU after the A/D conversion, MCU notes the working current value in the whole frequency range, and after intact to whole frequency range search, MCU Ji Suan goes out the frequency parameter under the corresponding maximum operating currenbt, and control PLL, follow the tracks of in this Frequency point.In actual use, corresponding to the human body different parts, its medium impedance may change, reflex to output stage, its operating current can change, and after MCU detected this variation, control PLL fine setting operating frequency made transducer and human body coupling readjust the optimum matching state.If the medium impedance is undergone mutation (as moving away to the air from human body), MCU detects reflected energy and surpasses the setting thresholding, and control PLL searches for again, changes tracking after finding good match point again over to.
1, MCU+ATC forms thermostatic control, adapts to the human body subjective sensation.
MCU regularly detects the sound head temperature, and control work pulse duration ratio, makes the sound head hull-skin temperature under the condition that maintains under the do-nothing operation state than human body temperature Lue height (about 38 ℃), feels the most comfortable being advisable when human body is contacted again.
2, each several part is formed:
A. in the block diagram, PLL comprises the reference frequency Fr that MCU produces, the phase bit comparison, loop filtering, why voltage controlled oscillator (VCO) and frequency divider (÷ N) etc. are referred to as the variant of PLL, be because among traditional PLL, its reference frequency Fr is fixed (being called reference frequency) and in using, Fr is variable herein, to realize search, the functional requirement of following the tracks of.
