Abstract
The invention discloses a solar tracking controller and the control method thereof. The controller comprises a light-proof sensor body, a sink hole formed on the sensor body and at least two light-sensitive elements distributed inside the sink hole. The solar tracking control method comprises the following steps: the light-sensitive elements inside the sink hole independently detect the intensity of the incident sun light in the sink hole and convert the light intensity signal into electrical signals which are output to a signal processing circuit; the signal processing circuit determines the deviation between the sun light direction and the sink hole axial direction according to the electrical signals from each light-sensitive element, and then adjusts the angle of the sensor body according to the deviation to ensure the direct solar radiation to the sink hole. The solar tracking controller has the advantages of simple structure and low manufacturing cost.
Description
Technical field
The present invention relates to the solar collecting device field, be specifically related to a kind of sun location tracking controller and the used control method of this controller.
Background technology
Because it is more and more higher to the cry of energy-saving and emission-reduction, solar collecting device has obtained development fast, as everyone knows, solar collecting device is to allow solar irradiation be mapped on the reflector, again the sunshine of reflector reflection is collected (focusing) and transformed absorption, the angle setting of reflector should guarantee that the sunlight of collecting can focus on together behind baffle reflection.The angle of reflector is fixed as a complete unit, and the crevice projection angle of sunshine changes, and adjusts so need follow the tracks of with this general direction to reflector sun direction of light; At present, solar position tracking transducer kind, specification are all many, but a common ground of existing solar position tracking transducer is that its structure is all very complicated, costs an arm and a leg.
Summary of the invention
The object of the present invention is to provide a kind of sun location tracking controller and the used control method of this controller, sun location tracking controller architecture of the present invention is simple, and manufacturing cost is low.
The present invention is achieved through the following technical solutions:
A kind of sun location tracking controller comprises lighttight sensor base, is provided with counterbore on sensor base, separately is laid with at least two light activated elements in counterbore.
The periphery of described counterbore bottom is provided with groove, and described each light activated element in the counterbore places in this groove.
Described light activated element in the counterbore is four.
Described four light activated elements in the counterbore evenly are laid in the periphery of described counterbore bottom.
The axial section of described counterbore is rounded.
This tracking control unit also includes treatment circuit, and described four light activated elements in the counterbore have eight terminals, and these eight terminals are end to end and form bridge circuit, and four wiring points are connected with treatment circuit.
Each is laid with a light activated element respectively on described sensor base opposite external side face, and this light activated element also is connected with described treatment circuit.
The line direction of two described light activated elements is consistent with the line direction of two light activated elements in the described counterbore at least on the described sensor base lateral surface.
A kind of sun location tracking control method, this method comprises the steps: at least
A, when the sun has just come out in the morning, when the sun had just come out after perhaps rain stopped, owing to do not have sunshine in the counterbore, need to adjust the reference position earlier: two light activated elements that are laid in the relative lateral surface of sensor base sensing are respectively injected the sun light intensity of both sides, and its light intensity is converted into electric signal exports treatment circuit to;
The electric signal that b, treatment circuit are imported according to two light activated elements of the relative lateral surface of sensor base, judge the deviation between sunshine direction and the counterbore axial direction, adjust the angle of sensor base again according to the deviation of being calculated, solar energy is injected in the counterbore, after sunshine was injected counterbore, the signal that treatment circuit is imported two light activated elements on the relative lateral surface of sensor base did not deal with;
C, separately be laid in light activated element sensing in the light tight sensor base counterbore and inject sun light intensity in the counterbore, and its light intensity is converted into electric signal exports treatment circuit to;
The electric signal that d, treatment circuit are imported according to each light activated element in the counterbore is judged the deviation between sunshine direction and the counterbore axial direction, adjusts the angle of sensor base again according to the deviation of being calculated, and the sunshine direct projection is gone in the counterbore.
It should be noted that because in use, sun location tracking controller of the present invention is to be installed on the reflector and with reflector to be synchronized with the movement, so " adjusting the angle of sensor base " promptly " adjusts the angle of reflector ".
