Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the circuit diagram of the control circuit of the utility model embodiment.
Detailed description of the invention
Below by detailed description of the invention, the utility model is described in further detail:
Reference numeral in Figure of description comprises: U-shaped frame 1, rolling curtain roller 2, slot 3, press strip 4, motor 5, curtain 6, control box 7, photodiode VD, resistance R1, resistance R2, resistance R3, resistance R4, resistance R5, resistance R6, resistance R7, electrochemical capacitor C1, electric capacity C2, motor M, reset switch SB, changeover switch S1, switch S 2
As shown in Figure 1, a kind of automatic light-adjustment curtain 6 comprises screw and is connected to U-shaped frame 1 on wall, and shape size and the window of U-shaped frame 1 match.The upper side frame of U-shaped frame 1, left frame and left frame are all straight groove structure and fit with the top of window, the left side and the right respectively.Left end in the upper side frame of U-shaped frame 1 is provided with the motor M of motor 5(and Fig. 2 of tubulose), the output shaft of motor 5 connects rolling curtain roller 2, and rolling curtain roller 2 is connected in upper side frame by bearing.The right-hand member of rolling curtain roller 2 connects slot 3, and slot 3 is the zipper structure of 1/2nd, and one end of slot 3 connects the top of curtain 6, and the other end of slot 3 connects the bottom of curtain 6.Slot 3 can slide along the left frame of U-shaped frame 1.The bottom of curtain 6 be socketed with there is constant weight can by press strip 4 stretching for curtain 6.Be provided with control box 7 in the left frame of U-shaped frame 1, control box 7 is provided with for controlling curtain 6 control circuit with an automatic light meter.The outer wall of control box 7 is welded with control panel, control box 7 has opening and can press reset switch SB.
As shown in Figure 2, the outer wall of control box 7 is equipped with control panel, control panel is provided with motor M and normally closed switch S 2, reset switch SB and the switch S 2 of the opening wide parallel connection in control box 7 is also connected anode.The other end of reset switch SB connects one end of the 4th pin resistance R4 and the anode of photodiode VD of amplifier KD28.Series capacitance C2 and resistance R7 between 3rd pin of amplifier KD28 and the 5th pin, connects motor M between the 3rd pin and the 5th pin simultaneously.7th pin of amplifier KD28 connects the 1st pin and connects the anode of electrochemical capacitor C1 and one end of resistance R6, one end of other end contact resistance R1 of resistance R6 and the negative electrode of photodiode VD.2nd pin of amplifier KD28 connects the 8th pin and connects one end of the negative electrode of electrochemical capacitor C1, the other end of resistance R4 and resistance R5.The other end of resistance R5 connects one end of changeover switch S1, the 6th pin of amplifier KD28 and the negative pole of battery.The other end of changeover switch S1 is the gear can selected for changeover switch S1, four gears be followed successively by night, strong, in, weak, representing intensity of illumination is respectively night, high light, middle light and the low light level.Night, gear was unsettled, and strong gear is connected between resistance R1 and resistance R2, and middle gear is connected between the series arm of resistance R2 and resistance R3, weak gear contact resistance R3.
In work, photodiode VD and resistance R1, resistance R4 and resistance R5 form balanced bridge.When illumination is suitable, A, B 2 current potentials are identical, are the half of supply voltage, and output the 3rd pin of amplifier KD28 is also identical with the 5th pin current potential, and motor M does not turn, and curtain 6 maintains the original state.When outdoor optical is according to when strengthening, indoor illumination also strengthens, photodiode VD internal resistance diminishes, A point current potential rises, amplifier KD28 output the 3rd pin current potential raises, and the 5th pin current potential declines, and motor M rotates forward, curtain 6 is slowly closed, and weakens, till the resistance of photodiode VD rises to and make electric bridge rebalancing until indoor illumination.Otherwise when illumination weakens, motor M is reversed, and curtain 6 is slowly opened.Electrochemical capacitor C1 and resistance R6 plays time-lag action, and control procedure is slowly carried out, and can avoid the starting repeatedly causing motor M because wind accidentally blows curtain 6 open.
The power of indoor illumination can be divided into by force on demand, in, weak three gears select.To night, even if indoor illumination is turned on light and can not be reached that weak gear requires, curtain 6 can all open.As closed curtain 6, changeover switch S1 can be moved to " gear at night ", at this moment A point current potential height overall is in B point current potential, and motor M rotates forward, and curtain 6 is closed.
When motor M is in curtain 6 standard-sized sheet or full cut-off, still have electric current.The switch S 2 of extreme position automatic stop must be arranged on for this reason.When motor M runs to extreme position, switch S 2 disconnects, and power supply is cut off.When restarting, click reset switch SB, circuit ON curtain 6 exits extreme position, and switch S 2 is recovered to connect, and control circuit can normally control again.
Control circuit and battery are contained in a control box 7 and are placed in the left frame of U-shaped frame 1, and the top of photodiode VD in control box 7 can not by light direct irradiation.
Above-described is only embodiment of the present utility model, and in scheme, the general knowledge such as known concrete structure and characteristic does not do too much description at this.Should be understood that; for a person skilled in the art, under the prerequisite not departing from the utility model structure, some distortion and improvement can also be made; these also should be considered as protection domain of the present utility model, and these all can not affect effect and the practical applicability of the utility model enforcement.The protection domain that this application claims should be as the criterion with the content of its claim, and the detailed description of the invention in manual etc. record the content that may be used for explaining claim.
