Provided with lifting drive control circuit in the control board, described lifting drive control circuit theory diagrams are as schemed
Shown in 5, by interior reference signal produce shaping circuit, outer reference signal shaping circuit, signal gating circuit, frequency and phase discrimination circuit,
Low-pass filter circuit, drive circuit, sampling amplification circuit, comparison circuit, motor speed signal shaping circuit composition.
Interior reference signal generation circuit is made up of quartz oscillator and frequency divider.Quartz oscillator produces stable
Waveform, after divided device, the frequency signal required for output, while the waveform produced to oscillator has carried out shaping,
Waveform is set to become square wave or pulse signal with precipitous rising and falling edges.
As shown in fig. 6, outer reference signal shaping circuit and motor speed signal shaping circuit are by resistance R1~R3, electric capacity
C1~C3, diode V1, V2 and operational amplifier N1 compositions, can be by it with filtering, amplitude limit and waveform translation function
Its waveform signal is shaped to the square wave or pulse signal of suitable phase frequency detector needs.
As shown in Fig. 7, when outer reference signal occurs in input, outer reference signal is filled by R1 and V1 to C1
Electricity.Because the discharge circuit time constant that R2 and C1 is constituted is normal much larger than the charging circuit time that R1 and C1 is constituted
Number, therefore will maintain high level in A points.The high level will make frequency divider keep reset state, its closing is output to D1A
The interior reference signal of 2 pin of OR gate, while outer reference signal is inputted from 1 pin of D1A OR gates, it is defeated from 3 pin output ends
Go out there is provided frequency and phase discrimination circuit is given, be used as the reference signal of frequency and phase discrimination.When removing outer reference signal, C1 passes through R2
Electric discharge, A points become low level, and 2 pin of the interior reference signal of frequency divider output to OR gate, the 3 pin output through OR gate is sent to
Frequency and phase discrimination circuit, is used as the reference signal of frequency and phase discrimination.
As shown in figure 8, D1 and R1 constitutes frequency and phase discrimination circuit, reference rotation speed signal is inputted from D1 14 pin,
Motor speed signal is inputted from D1 3 pin, and frequency and phase discrimination result is exported from D1 13 pin.Phase frequency detector is by electricity
The frequency and phase of machine tach signal are compared with the frequency and phase of reference rotation speed signal, are produced not according to different situations
Same output.When the frequency of motor speed signal is less than the frequency of reference rotation speed signal, phase frequency detector output high level；
When the frequency of motor speed signal is higher than the frequency of reference rotation speed signal, phase frequency detector output low level.When the frequency of the two
When rate is equal, phase frequency detector compares the phase of the two, when the phase of motor speed signal lags behind the phase of reference rotation speed signal
During position, phase frequency detector output positive pulse；When the phase of motor speed signal is ahead of the phase of reference rotation speed signal, mirror
Frequency phase discriminator exports negative pulse.When the frequency of the two is equal and during identical phase, phase frequency detector is output as high-impedance state.
Low pass filter is made up of R2, R3, C1, C2 and C3, and it is the pulse letter for exporting phase frequency detector that it, which is acted on,
Number filtering is DC level.
The common effect of phase frequency detector and low pass filter is exactly the output one when motor speed is less than egulation rotating speed
Higher level, and when motor speed is higher than egulation rotating speed, export a relatively low level.
Shown in Fig. 9, drive circuit is sampling switch type of drive, and the function of drive circuit is to work as low pass filter
Output level it is higher when, provide stronger driving to motor, accelerate motor；When the output level of low pass filter is relatively low
When, weaker driving is provided motor, makes decelerating through motor.
With reference to Figure 10, current foldback circuit is by operational amplifier N1, comparator N2, resistance Rq, R1~R6 and arteries and veins
Wide modulating driver composition.Rq in Fig. 7 is the Rq in Fig. 6.When power tube output current, in sample resistance
Pressure drop will be produced on Rq.Feeding comparator N2 in-phase input end after the amplified circuit amplification of the pressure drop, and N2's are anti-
The current potential of phase input is compared.When the output current of power output tube is no more than the size allowed, sample resistance Rq
On the amplified end of oppisite phase less than comparator N2 of pressure drop reference voltage Vref, comparator output low level, pulsewidth
Modulating driver normal work, driving power pipe normal work.When the output current of power output tube exceedes the size allowed
When, the reference voltage Vref of the amplified end of oppisite phase more than comparator N2 of pressure drop on sample resistance Rq, comparator
High level is exported, pulse-width-modulation driver output high level, the high level closes power tube, so as to reach protection power tube
Purpose.
The above described is only a preferred embodiment of the present invention, any formal limitation not is made to the present invention, though
So the present invention is disclosed above with preferred embodiment, but is not limited to the present invention, any to be familiar with this professional technology people
Member, without departing from the scope of the present invention, when the technology contents using the disclosure above make a little change or modification
For the equivalent embodiment of equivalent variations, as long as being the content without departing from technical solution of the present invention, the technical spirit according to the present invention
Any simple modification, equivalent variations and the modification made to above example, in the range of still falling within technical solution of the present invention.
