The utility model relates to an automatic curtain lifting control circuit, in particular to an automatic curtain photoelectric controller used to achieve automatic lifting. The automatic curtain photoelectric controller consists of a DC electrical source V, a general diode D, a photodiode VD, two triodes VT1 and VT2, two resistors R1 and R2 and a relay J; the relay J consists of contacts JK1 and JK2, push switches K1 and K2, a three single-pole/double-throw switch K3, a two-way alternating current motor M and an AC power of 220 volts. The device can automatically lift and land curtains according the strongness and the weakness of light, and the curtain can stop automatically when rising or landing to a scheduled position; when necessary, manual operation of curtain movement can also be available. The whole device is simple in structure and easy to be used.

Description

Curtain automatic lifting photoelectric controller

Technical field

The utility model belongs to curtain automatic lifting control circuit, specifically a kind of curtain automatic lifting photoelectric controller.

Background technology

As everyone knows, curtain keep the sun off because of it has, isolated sight line and beautify effect such as room and be widely used.But no matter be manually or electrically driven curtain, the operation of lifting curtain all will be by manually finishing, and is very inconvenient.

The utility model content

The purpose of this utility model is in order to solve the deficiency that the above-mentioned background technology exists, a kind of curtain automatic lifting photoelectric controller to be provided.

The technical solution of the utility model: curtain automatic lifting photoelectric controller comprises a direct current power supply V, general-purpose diode D, photodiode VD, two triode VT1 and VT2, two resistance R 1 and R2 and a relay J.Wherein, the minus earth of power supply V; Resistance R 1 is connected with back-biased photodiode VD, the input termination power V of resistance R 1, the output head grounding of photodiode VD; The output terminal of the base stage connecting resistance R1 of triode VT1, collector connects power supply V, grounded emitter by resistance R 2; The base stage of triode VT2 connects the collector of triode VT1, and collector connects power supply V, grounded emitter by the parallel circuit of relay J and diode D.

Described curtain automatic lifting photoelectric controller, its relay J is made of contact JK1 and JK2, push switch K1 and K2, single-pole triple-throw (SPTT) K switch 3, alternating-current bidirectional motor M and 220 volts of AC power.Relay contact JK1 links to each other with the cb winding of alternating current generator M by push switch K2, and contact JK2 links to each other with the ab winding of alternating current generator M by push switch K1; Other has single-pole triple-throw (SPTT) K switch 3, its 1 termination power, and 2 ends link to each other with the ab winding of alternating current generator M, and 3 ends are vacant, and 4 ends link to each other with the cb winding of alternating current generator M.

Advantage of the present utility model is: the user only needs closed power switch, and curtain can be according to the strong and weak automatic lifting of illumination, and curtain can stop after being elevated to the precalculated position voluntarily; When needing, but also hand-operated lifting curtain.Whole apparatus structure is simple, easy to use.

Embodiment

Describe the physical circuit of the present utility model and the course of work in detail below in conjunction with drawings and Examples:

Fig. 1 is curtain automatic lifting photoelectric controller circuit theory diagrams, comprises a direct current power supply V, general-purpose diode D, photodiode VD, two triode VT1 and VT2, two resistance R 1 and R2 and a relay J.The minus earth of power supply V; Resistance R 1 is connected with back-biased photodiode VD, the input termination power V of resistance R 1, the output head grounding of photodiode VD; The output terminal of the base stage connecting resistance R1 of triode VT1, collector connects power supply V, grounded emitter by resistance R 2; The base stage of triode VT2 connects the collector of triode VT1, and collector connects power supply V, grounded emitter by the parallel circuit of relay J and diode D.

Fig. 2 is the circuit theory diagrams of Fig. 1 repeat circuit J, comprises contact JK1 and JK2, push switch K1 and K2, single-pole triple-throw (SPTT) K switch 3, alternating-current bidirectional motor M and 220 volts of AC power.Relay contact JK1 links to each other with the cb winding of alternating current generator M by push switch K2, and contact JK2 links to each other with the ab winding of alternating current generator M by push switch K1; Other has single-pole triple-throw (SPTT) K switch 3, its 1 termination power, and 2 ends link to each other with the ab winding of alternating current generator M, and 3 ends are vacant, and 4 ends link to each other with the cb winding of alternating current generator M.

The utility model course of work is as follows:

(1) daytime, because the irradiation of high light, the back resistance of photodiode VD reduces, thereby dividing potential drop reduces, and makes triode VT1 end, triode VT2 conducting, relay J is in closure state because of there being electric current to flow through in the coil, and promptly its contact JK1 disconnects, contact JK2 closure; At this moment, the energising of the ab winding of motor M, the running of motor forward is fallen curtain; When curtain dropped to the precalculated position, the cross bar compressing push switch K1 of curtain bottom disconnected K1, and motor M shuts down.

When (2) evening or light were very weak, the back resistance of photodiode VD increased, thereby dividing potential drop increases, make triode VT1 conducting, triode VT2 ends, and relay J is in off-state because of no current in the coil flows through, be that its contact JK2 disconnects contact JK1 closure; At this moment, the energising of the cb winding of motor M, the motor antiport rises curtain; When curtain rose to the precalculated position, the cross bar compressing push switch K2 of curtain bottom disconnected K2, and motor M shuts down.

(3) when stirring single-pole triple-throw (SPTT) K switch 3, can realize the hand-operated lifting of curtain: connect 1,2 ends, can fall curtain; Connect 1,4 ends, can rise curtain; Connecting 1,3 ends, is off-position.
