Description
Technical field:
The invention belongs to the Application of Solar Energy field; Be particularly related to a kind of self-powered sun light tracking sensor device; Especially a kind of tracker is when steady state (SS); Whole tracker is 0 power consumption, improves solar energy photovoltaic system efficient to greatest extent, is applicable to two-dimensional tracking controls such as solar photovoltaic generation system, solar cooker, solar water heater.
Background technology:
In numerous relevant design; Purpose all is can follow the track of sunshine motion in order to control solar panel; Solar motion can be followed and perpendicular to sunray in the plane of control solar panel; The normal that is solar panel is parallel with sunray, improves photovoltaic efficiency to greatest extent.But common tracking control system all exists defective or deficiency:
1, most of both at home and abroad at present sunshine detection means of using, nothing more than using photoresistance or photodiode etc., indexs such as the sensitivity of this type device and the linearity are all pretty good, can be used for emulation people's eyes.Just get into the saturation region when sunshine is powerful in 500Lux, light intensity is 100, and when 000LUX was above, light resistance sharply descended, and causes photosensitive device to get into degree of depth saturation region, directly has influence on the reliability of photometry device, and this sight is similar to human eye can't look at sunshine straight.Therefore, have to adopt all shading dim light measures, get into the saturation region to avoid photoelectric curve, make total system greatly complicated, sensitivity and reliability also descend thereupon.
2, for this reason; The silicon photocell of employing is also arranged as light detector spare, like CN201392479Y, and CN201837893U; Four silicon photocells are in the same plane; And being separated into four light sample region by a cross light barrier or shadow shield, cornerwise two silicon photocells form one group, the variation of the corresponding East and West direction and the angle of pitch.Above patented technology; Unreasonable on the assembling skill of photometry device, also science not, the photometry device can only receive light in the front; Can't detect sunshine from the side or the back side; Cause the photometry device detection at any time not arrive sunshine, its reason: after one day tracking (promptly follow the sun and follow the tracks of one-period from the east to the west) of completion, then it is dark gets off; The light of the sun in second day morning when rise in local horizon in the east can only shine the back side of photometry device, is to cause to realize returning automatically one of reason in the east.They are two years old; If taked certain to force back eastern measure, make solar panel in the morning turn in the east, then begin to rain; Tracker stops to follow the tracks of; To fine sunny after the afternoon, sunshine at this time can only shine the side or even the back side of photometry device, and this also is the reason that causes reliability to descend greatly and comply with.Adopt structures such as complicated dim light or shading, can only receive light in the front, control system is difficult to realize return eastern function automatically or search for sunshine automatically.Common tracker all is to have added ancillary methods such as clock control, timer control, photometry unit, the back side at present, could realize getting back to function in the east, causes control system quite complicated, has increased the electrical source consumption of whole Detection & Controling circuit.
3, the design that has is with the change algorithm of solar motion track throughout the year, is cured to single-chip microcomputer after the programming, no matter fine raining, the loyal throughout the year scholar of controller carries out on ground the instruction of program curing.There are two defectives in this design: the one, and the longitude and latitude that the program curing incompatibility is different; The 2nd, tracking and driving system is overcast and rainy; Also to carry out unnecessary tracking and consume limited accumulator electric energy; Utilize the electric energy of the not at all easy lifting of sun tracking mechanism, but lot of consumption is in topworks, and topworks operation too frequently causes losing more than gain on the whole.
4, the mechanism design that has become per a few minutes with solar panels towards the four corners of the world four direction angle of tuningout initiatively; Whenever depart from a direction; The trend that system changes with regard to once sampling photovoltaic value is if the photovoltaic value is a downward trend, then toward the reverse direction adjustment: if the photovoltaic value is the trend that rises; Then continue the adjustment angle, and maintain.This type design exists topworks's operation too frequently to cause losing more than gain on the whole photovoltaic efficiency equally.
