Abstract
The utility model relates to a controller for forward-backward rotation of a light-control motor, which is used for the automatic opening-closing of a curtain. The controller comprises the motor (1) and a light-control circuit (2); the light-control circuit (2) comprises a trigger switch (21), a Schmitt trigger (22), a phase inverter (231), a monostable trigger I (232), a monostable trigger II (233), a power amplifier (24) and a power supply (25). As for the controller, a photoresistor is utilized as the trigger switch and a switch signal is transmitted through the Schmitt trigger and the power supply, and the controller has the advantages of being simple in circuit, strong in interference resistance and low in cost, and enabling the forward-backward rotation operation of the motor to be convenient and stable.
Description
Technical field
The utility model relates to a kind of light-operated motor positive and negative rotating controller, belongs to photoelectricity automatic control technology field.
Background technology
Progress along with society, popularizing of the raising of people's living standard and photo-electric control technology, household electrical appliance have been applied to the various aspects of family, but also there is certain deficiency aspect the control automatically at the photoelectricity of curtain, especially in the prior art in the light-operated motor positive and negative rotating controller, mostly adopt relay and travel switch in its control circuit, cause its circuit structure complexity, cost height, fluctuation of service.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and convenient stable, strong interference immunity of a kind of, motor rotating operation simple without relay and travel switch, circuit structure and the low light-operated motor positive and negative rotating controller of cost are provided.
The purpose of this utility model is achieved in that a kind of light-operated motor positive and negative rotating controller, and it is characterized in that: described controller includes motor and light-operated circuit; Described light-operated circuit includes trigger switch, Schmidt trigger, inverter, monostable flipflop one, monostable flipflop two, power amplifier and power supply unit; Described trigger switch is made of photo resistance, described Schmidt trigger is made of 555 timers, described trigger switch is connected to Schmidt trigger, described monostable flipflop one is made of 555 timers, described monostable flipflop two is made of 555 timers equally, the signal of described Schmidt trigger is exported one the tunnel and is connected to monostable flipflop one through inverter, another road is connected to monostable flipflop two, and described monostable flipflop one all amplifies the rear drive motor through power amplifier with the output signal of monostable flipflop two; Described power supply unit is made of bridge rectifier filter circuit and voltage-stabiliser tube, described power supply unit is powered to entire circuit, and described power supply unit is connected to described trigger switch, Schmidt trigger, inverter, monostable flipflop one, monostable flipflop two and power amplifier.
The beneficial effects of the utility model are:
Utilize photo resistance as trigger switch, and transmit switching signal, have that circuit structure is simple, convenient stable a, strong interference immunity of motor rotating operation, advantage that cost is low by Schmidt trigger and monostable flipflop.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is elaborated:
Fig. 1 is the utility model light-operated circuit schematic diagram.
Fig. 2 is the utility model light-operated circuit circuit diagram.
Among the figure:
Motor 1, light-operated circuit 2, trigger switch 21, Schmidt trigger 22, inverter 231, monostable flipflop 1, monostable flipflop 2 233, power amplifier 24, power supply unit 25.
Embodiment
Referring to Fig. 1 and Fig. 2, the utility model relates to a kind of light-operated motor positive and negative rotating controller, and described controller includes motor 1 and light-operated circuit 2; Described light-operated circuit 2 includes trigger switch 21, Schmidt trigger 22, inverter 231, monostable flipflop 1, monostable flipflop 2 233, power amplifier 24 and power supply unit 25; Described trigger switch 21 is made of photo resistance, described Schmidt trigger 22 is made of 555 timers, described trigger switch 21 is connected to Schmidt trigger 22, described monostable flipflop 1 is made of 555 timers, described monostable flipflop 2 233 is made of 555 timers equally, the signal of described Schmidt trigger 22 is exported one the tunnel and is connected to monostable flipflop 1 through inverter 231, another road is connected to monostable flipflop 2 233, and described monostable flipflop 1 all amplifies rear drive motor 1 through power amplifier 24 with the output signal of monostable flipflop 2 233; Described power supply unit 25 is made of bridge rectifier filter circuit and voltage-stabiliser tube, 25 pairs of entire circuit of described power supply unit are powered, and described power supply unit 25 is connected to described trigger switch 21, Schmidt trigger 22, inverter 231, monostable flipflop 1, monostable flipflop 2 233 and power amplifier 24.
When using the utility model device, resistance decreasing when the photo resistance of trigger switch 21 is subjected to solar radiation, the incoming level of Schmidt trigger 22 reduces, the output level of Schmidt trigger 22 upset when reaching threshold voltage, output signal enters power amplifier 24 behind monostable flipflop 1 and monostable flipflop 2 233 subsequently, and the signal after the amplification exports turning to of motor 1 control motor to.
