Description
Technical field
The utility model relates to field of solar thermal power generation, relates in particular to a kind of solar panel automatic tracking system.
Background technology
The development of sensor technology makes the use of sun power enter new epoch, and series of new solar cell continues to bring out, but conversion efficiency is not high, and cost is very expensive.When general placement solar panel, towards fixing, and the position of the sun is different, cannot ensure that sunshine is all the time perpendicular to cell panel, and conversion efficiency is reduced, and causes required cell panel area to increase, and equipment cost increases, and is unfavorable for promotion and application.
Current existing design proposal has: timing method, and according to the sun movement angle of middle per minute on high, calculate the angle that solar panel per minute should rotate, thereby determine the rotating speed of motor, make cell panel according to the position of the sun and corresponding variation.This method is called timing method. and its advantage is that circuit is simple, but due to the asynchronism(-nization) of Various Seasonal sunrise sunset, can reduce the degree of accuracy that this system is adjusted.Coordinate method, by 3 phototriodes be placed on different towards, one vertically towards sky, one towards positive east, another is towards positive west.The sun is irradiated to the light intensity difference of 3 photosensitive tubes from different perspectives, the photocurrent intensity difference that they produce.Sunshine direction can change with the positive angle p in east and the relation of light intensity (or photocurrent).Adjust the angle of solar panels according to 8 values, make solar panel always towards the direction of the sun.It is higher that its advantage is to adjust degree of accuracy, but it is too complicated to realize circuit.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of solar panel automatic tracking system.
The technical scheme that the utility model solves the problems of the technologies described above is as follows: a kind of solar panel automatic tracking system, comprise power supply, and described power supply is connected with sensing acquisition module, data processing module, CPU control module, stepper motor respectively; Described sensing acquisition module is connected with data processing module, realize collection and the processing of data, described data processing module is connected with CPU control module, realize analysis, the identification of data, described CPU control module is connected with stepper motor, according to the change of data-signal, CPU control module control step motor is made corresponding change.
Described sensing acquisition module is bridge circuit by the circuit theory that photoresistance realizes signals collecting, the output signal of circuit only be radiated at two photoresistance on the relative value of light intensity relevant, be not subject to the impact of external environment, increased the antijamming capability of device.
On the basis of technique scheme, the utility model can also do following improvement.
Further, described data processing module comprises: linear amplification unit, zero potential adjustment unit, rp unit, perturbation screen unit.Described data processing module adopts the non-amplification connection of swinging to, by operation amplifier unit and the linear amplifying unit of peripheral resistor group thereof, zero potential adjustment unit is to offset the direct current signal of zero point drift, because comprising a certain amount of undersuing after zeroing, provide positive voltage signal with rp unit for next stage circuit, input signal is judged, in the time that the intensity of output signal is greater than certain value, give high level signal of next stage; Otherwise, low level signal is provided, can shield like this disturbance of some tiny signals, make the work of system more stable.
The beneficial effects of the utility model are: simple in structure, control highly sensitively, and can effectively improve the utilization factor of solar panel to sunshine.
