Provide embodiments of the invention below in conjunction with accompanying drawing.
Fig. 1 is a theory diagram of the present invention.
Fig. 2 is triangular wave generator circuit figure of the present invention (A1, A2, A3, A4 are a four high guaily unit LM324).
Fig. 3 leads control circuit, frequency dividing circuit, medium-frequency pulse generation circuit, modulator circuit figure (A5, A6, A7, A8 are that one four fortune is revolved LM324) for medicine of the present invention.
Fig. 4, Fig. 5 are power amplification circuit of the present invention, power circuit diagram.
As shown in Figure 1: A1 is a comparator, and output is square wave.A2 is an integrator, and output is triangular wave.The reference level of comparator is+5V, power supply is through R01, the 2.5V that obtains after the R02 dividing potential drop is added on inverting input 2 feet of A1, the in-phase input end of A1 is connected on by R4, on the potentiometer that R5 forms, obtain the triangle wave voltage of A2 output, when this voltage is higher than 2.5V, the square wave of an about 3.5V of A1 output, when the triangular wave of A2 output is lower than 2.5V, the square wave of an about 1.5V of A1 output, the output voltage of A1 is through the R03 current limliting, D01, the pressure control amplitude limit of D02 is sent on the K1-1 prescription selector switch, through selecting the corresponding resistance of prescription, deliver to reverse input end 6 feet of A2, and charge to C21, A2 is an integrator, in-phase input end 5 feet are received on the 2.5V reference voltage, and the outfan 7 feet output of A2 is 0 with 2.5V, linear good continuous positive and negative triangle wave voltage, this voltage is delivered on A3 voltage follower in-phase input end 10 feet, delivers to R1(15K Fig. 2 through isolating from outfan 8 feet of A3).A5 gets to close amplifier.By adjusting W1(68K) trimmer potentiometer, make peak dot and OV snap on the triangular wave of A5 outfan 7 feet, so just having obtained one, to go up peak dot be that OV bears triangular wave.
Need carry out medicine ion and import when some disease of treatment, the above-mentioned like this peak dot of going up is regulated and just can be realized having treated through dutycycle control, modulation, power amplification, dosage again by the negative continuous triangle ripple of 0 monolateral band.But some disease does not need medicine to import and the positive and negative double-side band triangular wave of needs is treated.Therefore lead switch by the K2 medicine and will bear triangular wave and become positive triangular wave, one positive one negative symmetrical triangular ripple has so just been arranged through the A6 phase inverter.This can not be used for the treatment of, because one positive one negative symmetrical wave cancels out each other, we is synthetic with it again so must be from the time respectively positive and negative triangular wave be shielded, and could realize connecing from a last positive triangular wave of time the continuous double-side band triangular wave of a negative triangular wave.The square wave of A1 output among Fig. 1, the triangular wave of A2 is to negative integration during greater than 2.5V, and the triangular wave of A2 is to positive integration during less than 2.5V.From the time is corresponding one by one and synchronous, if behind the square wave two divided-frequency with A1, controlling a door allows triangular wave pass through to shield worn-out positive triangular wave behind the positive triangular wave, and allow negative triangular wave pass through, just can synthesize useful electrical waveform, the square wave of A1 outfan 1 foot is through R31, D01, send into A4 in-phase input end 12 feet behind the D02 amplitude limit, A4 is a homophase input proportional amplifier, mainly be in order to reduce influence to functional generator, simultaneously square wave is amplified to the level of TTL digital circuit energy operate as normal, deliver to input 14 feet of IC1 74LS93 Fig. 3 from outfan 14 feet of A4,74LS93 is 2,8 frequency devices, send into the base stage of delivering to V1 9015 after the input 13 foot paraphase of IC2 74LS27 nor gate from the output of 12 feet through R8 from the signal of 2 frequency division output terminal, 12 feet output, V1 9015 is PNP transistors, its emitter stage is received+5V, colelctor electrode is received-5V by R9, its effect is to transfer the positive logic level that IC2 12 feet are exported to the mixed logic level, export to R5 and R6 from colelctor electrode then, the base stage of R5 control V3 9015PNP pipe, the base stage of R6 control V4 9014NPN pipe, V3 like this, V4 just is equivalent to two doors, when the V4 conducting then of V1 positive level, door is opened and is allowed positive triangular wave pass through, meanwhile the anti-cut-off gate partially of V3 is closed, negative triangular wave can not pass through, opening triangular wave when V1 negative level V3 conducting then door passes through, meanwhile the V4 cut-off gate is closed, and positive triangular wave can not pass through.Emitter stage at V3, V4 has just obtained from time difference one positive one negative successive double-side band triangular wave like this.What deserves to be mentioned is that functional generator can not adopt positive-negative power supply for above-mentioned reasons, otherwise can't adopt waveform synthetic method realization medicine to lead required waveform.
Control about modulation duty cycle: require to transfer triangular wave with the 1KHZ pulse.A8 has formed a 1KHZ agitator and since with A5, A6, the A7 1KHZ pulse that the common-battery source produces on the chip that coexists be the pulse of double-side band mixed logic, this pulse is delivered to V from the A8 outfan through R12
89014 transistorized base stage V8, effect is positive monolateral pulse with the 1KHZ pulse transition, the manipulator that cooperates V5, V6 composition from level, the monolateral positive pulse of V8 colelctor electrode output is delivered to the transistorized base stage of V9.9015 by R16, after the paraphase from colelctor electrode with grid and the source electrode of 1KHZ pulse to V5, V6, R7(300K) effect is to produce pressure reduction, just can make V5, V6 conducting, and V5, V6 are V
MosPipe utilizes V
MosIt is not controlled to manage anti-phase conducting, and forward conduction must add the characteristics of positive voltage at grid, so be positive triangular wave or the exportable modulating wave that is envelope with positive and negative double-side band triangular wave of source electrode of negative triangular wave V6 under the effect of positive pulse no matter V5 drain electrode adds.The realization of dutycycle is 4 frequency division ripples with IC1 output, and 8 frequency division ripples have obtained the dutycycle square wave of 1: 1 and 1: 3 again by the IC2 combination.1: 3 square wave is again after the paraphase of V29014 transistor, become the square wave of 3: 1 dutycycles, be added on the switch of K1-2, because K1-1 is with the one-level switch among K1-2 and Fig. 2 with 1: 1 square wave, K1-2 has also changed dutycycle automatically when changing prescription, and duty cycle signals is sent into V7V through behind the K1-2
MosThe grid of pipe, when high level came, the V7 conducting utilized V
MosConducting resistance is very little, the 1KHZ signal shorts that R12 is sent here and the short circuit of V8 emitter-base bandgap grading base stage ends, manipulator does not have positive pulse, can not conducting, so obtained whole required waveforms in dosage regulator potentiometer upper end, A7 delivers to D1, D2 light emitting diode after triangular signal that one voltage follower obtains the V5 drain electrode is isolated in addition, and red luminotron is bright when negative triangular wave occurs, edge color luminous tube is bright when positive triangular wave occurs, and has played the demonstration effect that prescription and medicine are led state.
