Description
Technical field:
The utility model relates to a kind of sun blind, specifically a kind of light-operated louver curtain that can automatically open or close according to indoor light power certain angle.
Background technology:
At present, sun blind have been widely used in the places such as household, office, and sun blind have that daylighting is even, air permeability good, lower-price characteristic.Existing sun blind are all folding angles of the moving adjusting vane of armrest, there is no on the market a kind of sun blind that can automatically control according to indoor light intensity.
Summary of the invention:
In order to overcome the defect of prior art, the utility model provide a kind of simple in structure, easy to process, with low cost, be applicable to light-operated louver curtain indoor, that light sensing position changeable is moving.
A kind of light-operated louver curtain, comprise sun blind, motor, shaft coupling, light sensing circuit and control circuit, light sensing circuit comprises: light resistor circuit, analog to digital conversion circuit, single-chip microcomputer one, radio transmitter, and control circuit comprises: wireless receiving circuit, single-chip microcomputer two, motor-drive circuit; It is characterized in that: described light sensing circuit is attached to indoor, in described light sensing circuit, light resistor circuit is connected with single-chip microcomputer one by analog to digital conversion circuit, single-chip microcomputer one is connected with radio transmitter, in described control circuit, wireless receiving circuit is connected with single-chip microcomputer two, single-chip microcomputer two is connected with stepper motor by motor-drive circuit, and motor is connected with sun blind rotating shaft by shaft coupling; Whole device adopts DC power supply.
The utility model is on existing sun blind, to install stepper motor and control circuit additional, at the indoor light sensing circuit that installs additional, utilization is installed at indoor light resistor circuit inductance indoor light intensity, by analog to digital conversion circuit, light intensity is converted to digital quantity, data after conversion send single-chip microcomputer one to, between single-chip microcomputer one and single-chip microcomputer two, carry out transfer of data by radio transmitter and wireless receiving circuit, single-chip microcomputer two passes through motor-drive circuit control step electric machine rotation according to the light intensity size receiving, and then the folding angle of control sun blind, reach indoor light is controlled to the effect in certain optimum range, adopt Wireless Data Transmission, can conveniently adjust light sensing circuit placement location, realize indoor diverse location and reach required light intensity.The utlity model has the features such as simple in structure, easy to process, stable performance, light sensing position changeable be moving, be applicable to the place that classroom, conference room, office etc. need light intensity in conditioning chamber.
Accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model.
Wherein 1-sun blind; 2-stepper motor; 3-shaft coupling; The rotating shaft of 4-sun blind
The specific embodiment:
Specific implementation method below in conjunction with accompanying drawing explanation the utility model embodiment:
As shown in Figure 1, adopt as the prior art sun blind 1 structure, different is at the indoor light sensing circuit that is equipped with, control circuit is housed on sun blind, light sensing circuit comprises light resistor circuit, analog to digital conversion circuit, single-chip microcomputer one, radio transmitter, control circuit comprises wireless receiving circuit, single-chip microcomputer two, motor-drive circuit, light resistor circuit is connected with single-chip microcomputer one by analog to digital conversion circuit, single-chip microcomputer one is connected with radio transmitter, wireless receiving circuit is connected with single-chip microcomputer two, single-chip microcomputer two is connected with stepper motor 2 by motor-drive circuit, stepper motor 2 is connected with sun blind rotating shaft 4 by shaft coupling 3.
After switching on power, be attached to light intensity in indoor light sensing circuit meeting nernst cell, by analog to digital conversion circuit, intensity of illumination is converted to data signal and sends single-chip microcomputer one to, single-chip microcomputer one sends the intensity of illumination that converts data signal to single-chip microcomputer two by radio transmitter and wireless receiving circuit, single-chip microcomputer two is according to the light intensity size receiving and set the difference between light intensity, rotate by motor-drive circuit control step motor 2, stepper motor drives sun blind rotating shaft 4 to rotate by shaft coupling, thereby realize the automatic control of the folding angle of sun blind 1, reach indoor light is controlled to the effect in certain optimum range.
