Abstract
The utility model relates to a roller shutter door machine technical field, automatic voltage regulation circuit on rolling slats door current motor controller especially, compared with the prior art, this automatic voltage regulation circuit includes the alternating current input, stabilize DC output, D2 rectifier bridge heap, IC1 keeps apart opto -coupler and PWM control end, voltage variation through sampled signal, adjust the duty cycle of " PWM control end ", and keep apart the width of opening of photocoupler controlled Q1 switch tube through IC1, thereby reach the steady voltage of stabilizing DC output output direct current, as long as the automatic voltage regulation circuit is one input winding, reach very fixed stepless steady voltage, real -time pressure regulating, output voltage is undulant little, thereby reach roller blinds motor speed no. 1 to, pressure regulating control section is the low -pressure end in frequency transformer's output, thereby it keeps apart to reach the completion of high -low pressure, the lightning protection effect is good. The frequency transformer coiling is simple, and is with low costs.
Description
Technical field
The present invention relates to roller shutter door machine technical field, the automatic Regulation on particularly a kind of rolling screen door DC motor controller
Circuit.
Background technology
Rolling screen door controller of the prior art is two strands of input windings of coiling on Industrial Frequency Transformer, then according to civil power
Voltage is adjusted, when line voltage is less than 200V with relay closure boosting winding, so as to reach voltage regulation result but this
Voltage regulating mode has a disadvantage that：1st, pressure regulation point is few, and it is big unstable to easily cause output voltage fluctuation, rolling motor when voltage is different
Speed speed is far short of what is expected；2nd, by the switching of Control civil power high pressure winding, when causing to thunder, high pressure is easily by relay
Low voltage control end is channeled to from high-pressure side causes panel to damage, and lightning protection effect is poor, from the lightning protection effect for losing Industrial Frequency Transformer；3、
The input winding of Industrial Frequency Transformer is more, and coiling is more complicated, causes manufacturing cost high.
The content of the invention
For solving defect and problem in prior art existing for rolling screen door controller, there is provided a kind of rolling screen door direct current generator
Automatic voltage regulating circuit on controller.
The present invention for the solution technical scheme that adopts of its technical problem is：A kind of rolling screen door direct current generator control of the present invention
Automatic voltage regulating circuit on device processed includes alternating current input, stable DC outfan, D2 rectifier bridge stacks, IC1 isolation optocouplers
With PWM control ends；D2 rectifier bridge stacks are provided between alternating current input and stable DC outfan, after D2 rectifier bridge stacks
Voltage carries out sampling and obtains a sampled signal, by the change in voltage of sampled signal, adjusts the duty of " PWM control ends "
Than, and Q1 switching tubes are controlled by IC1 isolation optocouplers open width, so as to reach the steady of " DC output end " output direct current
Pressure.
The invention has the beneficial effects as follows：Compared with prior art, on rolling screen door DC motor controller of the invention from
As long as dynamic regulating circuit one input winding, then with adopt according to the sampled signal after D2 rectifier bridge stacks control source to monolithic
Machine, change of the single-chip microcomputer according to sampled voltage, adjustment " PWM control ends " dutycycle and frequency, reach real stepless voltage-stabilizing, defeated
Go out voltage pulsation little, rolling motor speed one to.The Regulation Control of this control is carried out in the outfan of Industrial Frequency Transformer, so as to
Up to the completely isolated of high-low pressure, lightning protection effect is good；Industrial Frequency Transformer coiling is simple, low cost.
Description of the drawings
With reference to the accompanying drawings and detailed description to automatic on a kind of rolling screen door DC motor controller of the present invention
Regulating circuit is described further.
Fig. 1 is the structural representation of the automatic voltage regulating circuit on a kind of rolling screen door DC motor controller of the present invention.
Specific embodiment
As shown in figure 1, the automatic voltage regulating circuit on a kind of rolling screen door DC motor controller of the present invention includes alternating current
Stream input, stable DC outfan, D2 rectifier bridge stacks, IC1 isolation optocouplers and PWM control ends.Alternating current input with
Be provided with D2 rectifier bridge stacks between stable DC outfan, be provided with R3 resistance and D1 diodes after D2 rectifier bridge stacks, R3 resistance and
After D1 diodes in parallel, R3 resistance and D1 diode pair D2 rectifier bridge stacks, voltage carries out sampling and obtains a sampled signal, adopts
To single-chip microcomputer, single-chip microcomputer is controlled " PWM control ends " and is accounted for according to sampled voltage control source by the change in voltage of sampled signal
Empty ratio and frequency, and width is opened by what IC1 isolation optocouplers controlled Q1 switching tubes, it is straight so as to reach " DC output end " output
The voltage stabilizing of stream, is real stepless voltage-stabilizing, and output voltage fluctuation is little, so as to reach rolling motor speed one to pressure regulation is in work
The outfan of frequency power transformer, so as to reach the completely isolated of height, lightning protection effect is good；Industrial Frequency Transformer coiling is simple, low cost.
