Abstract
The invention relates to an automatic solar tracker. Highest solar intensity points are detected by use of photosensitive resistors sensitive to light intensities, and by taking differences of highest light intensities detected by the multiple photosensitive resistors as an input quantity of a servo motor, a cell panel is controlled to flexibly and accurately defect in two degrees of freedom. Such a system detects positions of the sun and the photosensitive sensors constantly and inputs detected signals after amplification into a single-chip microcomputer, how the solar panel deviates and a deviation angle are obtained through calculation and analysis in the single-chip microcomputer, and deviation signals drive the servo motor through a servo circuit and accordingly drive the cell panel to deflect so as to reach an optimal position. Through an onsite test, the apparatus provided by the invention is accurate in tracking and high in conversion efficiency, thereby having obvious realistic significance.

Background technology
Entering 21 century, along with developing rapidly of all trades and professions such as industry, the usage amount of Fossil fuel is great increase, people
Have to face two stern realities: resource worsening shortages and the great deterioration of ecological environment.In order to alleviate these problem generation
Jie Ge state all takes a series of policy and measure, vigorously supports and develops energy-conserving and environment-protective industry, wherein solar panel
It it is exactly an important field.Owing to Various Seasonal, area, time period sun light intensity point of maximum intensity always change, and other
The impact of uncertain factor, when utilizing solar energy, has naturally occurred as soon as a problem, that is, cell panel is the most certainly
Motion tracking sun direct projection so that transformation efficiency is the highest.
Summary of the invention
Technical problem: the problem existed for above-mentioned prior art, the present invention provides a kind of automatic sun energy tracker.
Technical scheme: the present invention relates to a kind of automatic sun energy tracker, uses the photoconductive resistance detection sensitive to light intensity
Sun light intensity point of maximum intensity, detects high light is strong the difference input quantity as servomotor according to multiple photoconductive resistance, controls electricity
Plate two degree of freedom in pond the most accurately deflect；The position of this system time the detection sun and light sensor, and will detect
Signal is input to single-chip microcomputer through amplification, show how solar panel offsets and offset through calculating and analysis in monolithic
Angle, this shifted signal is driven servomotor by drive circuit, and then drives cell panel to deflect, and arrives optimum position.
The method have the advantages that
1, apparatus of the present invention are tested by scene, and it is followed the tracks of accurately, transformation efficiency is high, has obvious realistic meaning.
2, apparatus of the present invention can regulate in real time along with the four seasons, one day sun direct projection different situations sooner or later, improves too
Sun transformation of energy efficiency.
Accompanying drawing explanation
Fig. 1 is apparatus of the present invention System Working Principle figures.
Fig. 2 is signal processing circuit figure in the present invention.
Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment further illustrates technical scheme.
As it is shown in figure 1, a kind of automatic sun energy tracker, use to the sensitive photoconductive resistance detection sun light intensity of light intensity
Strong point, detects high light is strong the difference input quantity as servomotor according to multiple photoconductive resistance, control cell panel two from
By degree the most accurately deflection；This system time detection sun and the position of light sensor, and by the signal detected through putting
It is input to greatly single-chip microcomputer, in monolithic, draws, through calculating and analysis, the angle how solar panel offsets and offset, should
Shifted signal is driven servomotor by drive circuit, and then drives cell panel to deflect, and arrives optimum position.
As in figure 2 it is shown, apparatus of the present invention use the photoconductive resistance that sensitivity is higher, it is distributed in 4 edges of cell panel
Heart position, light intensity is different, then its resistance is different, and the signal that Chip Microcomputer A/D gathers is different, and the data changed out are the most different, according to
The difference of the upper and lower photoconductive resistance of cell panel, as the input quantity of control system, calculates corresponding pulses signal through programmed algorithm,
Exported by single-chip microcomputer, control servomotor 1, regulating cell plate downward shift；R_Uin is cell panel top photoconductive resistance collection letter
Number, R_Din is that the photoconductive resistance of cell panel bottom gathers signal, through each amplifying, then carries out amplification of checking the mark, obtains output signal
Uout is transported to Chip Microcomputer A/D acquisition port.
