Description
Technical field
The utility model relates to the control circuit on a kind of solar automatic tracker, specifically a kind of photovoltaic electricity solar automatic tracker solar tracking circuit.
Background technology
The automatic sun tracking controller is used for solar attachment, the rotation of control solar attachment.In the existing automatic sun tracking controller, an a kind of light sensor and Schmidt trigger or monostalbe trigger of being to use arranged, constitute light-operated Schmidt trigger or light-operated monostalbe trigger and control stopping, changeing of motor, but because throughout the year, the strong and weak variation range of early, middle and late surround lighting and sunlight is all very big, so the big sun with sort controller can be difficult to the round-the-clock tracking sun of the four seasons by receiving trap, the tracking Control effect is relatively poor relatively.
Summary of the invention
The purpose of this utility model is to design a kind of photovoltaic electricity solar automatic tracker solar tracking circuit.

Description of drawings
Fig. 1 is the structural representation that photodiode is arranged at housing two sides.
Fig. 2 is circuit theory diagrams of the present utility model.
Embodiment
Below in conjunction with drawings and Examples the utility model is described further.
As shown in the figure, the utility model comprises housing 1 and comparator circuit 3, the photosensitive sensing circuit 2 be located in the housing 1, and comparator circuit 3 is connected with photosensitive sensing circuit 2.Comparator circuit 3 comprises first comparator circuit and second comparator circuit.First comparator circuit comprises operational amplifier U1A, resistance R 1, and resistance R 1 is connected on 2 pin of operational amplifier U1A.Second comparator circuit comprises operational amplifier U1B, resistance R 2, and resistance R 2 is connected on 6 pin of operational amplifier U1B.
Photodiode D1 and photodiode D4 are installed on a side of housing 1, and photodiode D2 and photodiode D3 are installed on the opposite side of housing 1.
Principle of work of the present utility model is: when photodiode D1, D2, D3 and D4 were subjected to the naturally effect of light simultaneously, the central point voltage of potentiometer W1 and W2 was constant.If have only photodiode D1, D4 to be subjected to solar light irradiation, the internal resistance of photodiode D3 reduces, and the 3. pin current potential of U1A raises, 1. pin is exported high level, and photodiode D2 internal resistance simultaneously reduces, and the 5. pin current potential of U1B descends, by single-chip microcomputer output control signal, motor M is just changeed again.In like manner, if having only photodiode D2, D3 to be subjected to solar light irradiation, then by single-chip microcomputer output reverse control signal, motor M counter-rotating.When the illuminance that forwards housing (double as vertical sunshade plate) both sides to is identical, just stall of motor M.Ceaselessly in the migration process, the power of housing (vertical sunshade plate) both sides illuminance is alternate constantly at the sun, and motor M is changeed---stop, change---and stopped, and makes solar attachment face the sun all the time.4 photodiodes of the utility model intersect the benefit of arranging like this and are: when the 3. pin current potential of (1) U1A raise, 5. the pin current potential then reduced, and when the 5. pin current potential of U1B raise, 3. the pin current potential then reduced, and the rotating work that makes motor not only simply but also reliable.
