Description

Automatic timing controller for window curtain

The utility model belongs to electronic technology field, is a kind of device that curtain opens and closes of controlling.

At present, most of curtain need manually to open and close, and its switching of minority electrically driven curtain also needs Push switch, brings certain trouble for the live and work student, and is particularly more constant to the disabled person.

But the purpose of this utility model is the device that will provide a kind of timing controlled curtain to open and close.

Solution of the present utility model is that design is a kind ofly cut-off circuit by clock circuit, encoder, display, and the timing controller that relay and motor and travel switch constitute can set up on their own the time, makes the curtain automatic shutter.

Below in conjunction with accompanying drawing this practicality is newly specified:

Fig. 1 is the utility model circuit diagram;

Fig. 2 is the travel switch schematic diagram.

The utility model is made of power circuit 1, preparation power circuit 2, clock circuit 3, display 4, encoder 5, executive circuit 6,, power circuit 1 connects rectifier D by transformer B ₃-D ₆, connect voltage-stablizer IC again ₃Constitute, power circuit 1 connects preparation power circuit 2 and executive circuit 6 respectively, and preparation power circuit 2 is by relay J ₂, 1.5 Power supply, electrochemical capacitor C ₁Constitute, preparation power circuit 2 connects clock circuit 3 and encoder 5 again respectively, and clock circuit 3 connects display 4, and display 4 connects encoder 5, and encoder 5 has K ₀-K ₇Eight buttons.K ₀K ₇For manually controlling button, K ₁To K ₆Be key letter, encoder 5 passes through resistance R ₂Connect the triode BG in the executive circuit 6 ₁Base stage, executive circuit 6 is by triode BG ₁, BG ₂, relay J ₁Constitute, wherein BG ₂Emitter stage connect power circuit 1, its base stage is passed through resistance R ₄Connect BG ₁Colelctor electrode, BG ₂Collector connection relay J ₁, J ₁Two winding point J are arranged _1-1, J _1-2, J ₁During action, a _1-1With b _1-1, a _1-2With b _1-2Be communicated with J ₁During not adhesive, c _1-1With b _1-1, c _1-2With b _1-2Be communicated with a _1-1c _1-2Point connection power circuit 1, b _1-1Point is by travel switch K ₈Connect motor G and connect b again _1-2The point.Travel switch K ₈Be fixed on the curtain rod arm, two switch contacts of X, Y are arranged on the curtain rope.In power circuit 1,220 volts of voltages are through B transformation, D ₃-D ₆Rectification and ZC ₃After the voltage stabilizing, to the entire circuit power supply, in preparation power circuit 2, when power circuit 1 power supply, relay J ₂Adhesive, J _2-1The a of contact ₂With b ₂Conducting, to the time kind circuit 3, display 4 and encoder 5 power supplies, when power supply cuts off the power supply suddenly, J ₂Discharge J _2-1The C of contact ₂With b ₂Conducting, the power supply of 1.5V power supply, C ₁The short time discharge can make program stored reservation in the circuit.The button K of encoder 5 ₁To K ₆Can encode, can compile out the correct time that curtain opens and closes in the week, show by display 4, the time kind circuit 3 handle, supply with executive circuit 6 and carry out signals, promptly pass through resistance R ₂Power or do not power.K ₀And K ₇Be manual button, can directly control curtain after pressing and open and close.In executive circuit 6, encoder 5 is not to triode BG ₁Base stage when power supply, BG ₂Not conducting, relay J ₁Not adhesive, its contact J _1-1And J _1-2Middle b _1-1With c _1-1Point, b _1-2Point and c _1-2Point connects, and electric current passes through a _1-1Point is to c _1-2Point, b _1-2Point passes to motor G, as the curtain open mode, and travel switch K ₈K _8-1Point is closed, K _8-2Point disconnects, not conducting of circuit, and during the curtain closure state, K _8-2Closure, motor G clockwise rotates curtain is opened, and switch contact Y puts in place K _8-2Point disconnects, the motor stall.Encoder is to triode BG ₁Base stage when power supply, BG ₂Conducting, J ₁Adhesive, J _1-1And J _1-2A _1-1With b _1-1Point, a _1-2With b _1-2The point adhesive, when curtain is opened, K ₈K _8-1 closure, electric current is through a _1-1Point, b _1-1Point K _8-1Point inflow motor G ₁Pass through b again _1-2Point, a _1-2Point ground connection constitutes the loop, and motor G rotates counterclockwise curtain is opened, and switch contact X puts in place K _8-1Point disconnects, the motor stall.

The utility model is simple in structure, and is easy to use, and volume is little, and cost is low, and dependable performance is particularly suitable for luxurious hotel and has disabled person's family to use.
