Description
Technical field
The utility model relates to a kind of light signal sensing device.
Background technology
Along with continuous progress in science and technology, people's environmental consciousness strengthens gradually, and people are also more and more higher to the requirement of using energy source.With coal, oil is the resistance that the contamination type energy of representative is subjected to people gradually, and is the favor that the sustainable pollution-free green energy resource of representative is subjected to people gradually with water energy, wind energy, solar energy etc.Solar power generation is that people successfully utilize solar energy one of to use for the typical case that the mankind contribute.Solar power generation is the energy with the sunlight, generating on daytime and storage, and use evening, and safety and environmental protection is pollution-free, and is popular to people deeply.In order to make solar energy generating efficiency reach the highest, optical signal sensor generally all is installed, on device of solar generating so that make device of solar generating in real time over against sunlight.Traditional light signal sensing device, generally comprise a housing, two photocells are installed on housing, because two photronic sensitive surfaces are not on same plane, when sunlight is not that direct projection is when two photocells are middle, two photronic angles of solar light irradiation are different, different when so just causing two photronic output voltages, thereby make driving mechanism rotate two photocells, up to two photronic output voltage unanimities, so just reached the purpose of light signal sensing device over against the sun.Tradition light signal sensing device is simple in structure, and convenient to light, weak point is, in practice, be difficult to find two identical two photocells of the output signal of telecommunication under same illumination condition, therefore, tradition light signal sensing device lower to the light precision is unfavorable for making full use of of solar energy.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of light signal sensing device rational in infrastructure, higher to the light precision at above-mentioned deficiency.
For solving the problems of the technologies described above, this light signal sensing device comprises housing, its design feature is: the housing oral area be equipped with can optically focused lens, be provided with the adjacent setting of sensitive surface upper photocell, the next photocell, left side position photocell and right position photocell at grade in the housing, described photocell is that the center evenly distributes with the lens focus, and the processor to described photocell output signal of telecommunication contrast processing back output control signal also is installed in the housing.
The light signal sensing device of this structure is realized the light precision higher by the optically focused location structure.
The optically focused location structure mainly is meant the lens that are arranged on the housing, lens have the optically focused performance, when sun light positive is penetrated on lens, lens can be gathered into a focus spot with being close to parallel sunlight, at this moment, the sunlight intensity at focus spot place is identical with the sunlight intensity that sees through whole lens, but the light area dwindles greatly, and lens have played the effect of amplifying light intensity; In housing, also be provided with the upper photocell corresponding, the next photocell, left side position photocell and four photocells of right position photocell with the focus spot position, these four photronic sensitive surfaces are positioned on the same plane, and are that the center evenly distributes with the focus spot of lens; Like this, when sun light positive is penetrated lens, the focus spot that sunlight sees through the lens generation will be positioned at the lens focus place, and also be described four photronic symmetrical centre herein, therefore, this moment, four signals of telecommunication that photocell produced were identical, can not export the control signal that drives external agency's action after the processor contrast; When the lens of this optical signal sensor depart from sun light positive slightly and penetrate light, sunlight sees through the formed focus spot of lens also can depart from four photronic symmetrical centre, because focus spot has been assembled the sunray intensity of whole lens area, therefore the signal of telecommunication exported than other photocells of the signal of telecommunication exported of one or two photocell of mainly shining of focus spot is greatly a lot, at this moment, after the processor contrast is handled, to outwards export control signal, so that make this optical signal sensor of external drive mechanism urges timely, that follows the tracks of sunlight exactly just penetrates light.
As improvement, photronic sensitive surface is vertical with lens axis upper photocell, the next photocell, left side position photocell and right position is provided with.
Be provided with vertical of described four photocells with lens axis, can make the area of focus spot on the photocell sensitive surface behind the solar light focusing littler, following the tracks of sun light positive, to penetrate light more accurate.
As improvement, described lens are the Fei Nier lens, be coated with on the adjacent side of lens and photocell perspective film is housed.
Adopt the Fei Nier lens to use as collector lens, lens take up room littler, and spotlight effect is better.Be provided with after the perspective film, can strengthen the translucent effect of Fei Nier lens, help to strengthen the tracking accuracy of this optical signal sensor.
As further improvement, housing is provided with the cage of corresponding setting with lens, and the plane transmissive mirror is installed on the cage.
Cage is set on housing, can prevents external impurities, after on the cage transmissive mirror being set, both played the effect of insulation blocking lens, make things convenient for light to inject in the lens again, help the stable operation of this optical signal sensor attached on the lens.
In sum, adopt the light signal sensing device of this structure, rational in infrastructure, higher to the light precision, be adapted at using on the various solar energy systems, be particluarly suitable for using on the solar energy system that tracking accuracy has relatively high expectations, help to improve the utilization ratio of solar energy.
