Description

Visible light compound eye steady arm

Technical field

The present invention relates to a kind of visible light positioning system, can be fit to the position application of the visible lights such as ray trace location of solar photoelectric and photo-thermal.

Background technology

At present, solar energy tracking has been widely used in various solar energy application systems, track and localization technical development to sunshine is rapid, the general orientation of adjusting solar panel that sun light tracking is located is made up of photosensitive or heat sensitive component and some control system, photosensitive or heat sensitive component by being arranged on diverse location on the solar panel is to the difference of the induction amount of different angles sunshine illumination, import data into control system, the solar panel orientation is proofreaied and correct.Because the sunshine light path directly contacts with sensed components and parts without the intermediate medium beyond the air, the visual field of location is little, and the reaction velocity of system is slow, and the poor anti jamming capability of system.

Summary of the invention

For the visual field that overcomes prior art location little, the reaction velocity of system is slow, and the deficiency of the poor anti jamming capability of system, the invention provides a kind of visible light compound eye steady arm, employing optics compound eye structural and Circuits System are gathered visible light and are handled, this system can not only increase the visual field and the reaction velocity of location, and volume is little, in light weight, energy consumption is low, can be applied to easily in the track and localization of various solar panel arrays.

The technical solution adopted for the present invention to solve the technical problems is: comprise the dome-type compound eye; circuit module and dsp processor; adopt the convex lens assembling to join a semisphere compound eye; the hemisphere face of semisphere compound eye laterally is divided into 360 parts; vertically be divided into 90 parts; so just hemisphere face is divided into 32400 little lattice; each one of little lattice assembling is simple eye; each is simple eye to constitute by connecing cylindric optical fiber under the convex lens; each is simple eye to connect two photoresistance modules; be respectively adjacent row resistive module (a photoresistance and a fixed value resistance series connection that shields by vertical arrangement constitute) and row resistive module (constituting) by transversely arranged a photoresistance and a fixed value resistance series connection that shields; so just by resistive module forming circuit module; adopt row parallel connection or row paralleling model between the resistive module wherein, circuit module provides power supply by the external dsp processor of voltage sensor and by dsp processor.When light source shines to the compound eye hemisphere face, light source conducts to optical fiber after each simple eye convex lens amplifies focusing, optical fiber conducts visible light, transmission of visible light be directed at each simple eye corresponding photoresistance on, because each simple eye angle difference of accepting illumination, the intensity of illumination difference is accepted in its corresponding photoresistance, this photoresistance resistance reads magnitude of voltage and is sent to dsp processor by the parallel resistance module of voltage sensor to each row and each row like this because of being subjected to the illumination decrease also different.The circuit module paralleling model of being expert at of at first working, each row parallel resistance circuit is read magnitude of voltage, after 360 row circuit values finish, turn to the row paralleling model and begin the row parallel circuit is read magnitude of voltage by the dsp processor control circuit, after finishing, 90 column circuits values finish circuit working state, by dsp processor the data that read are handled, the common factor photoresistance module of the row of the row of magnitude of voltage maximum and magnitude of voltage maximum is the resistive module of asking, pairing simple eye according to it, can obtain the angle of pitch and the position angle of illumination.

The invention has the beneficial effects as follows: when illumination process compound eye lens group, compound eye convex lens group is amplified and focused light source light intensity, simultaneously convex lens fiber section down conducts visible light, has gathered visible light effectively and handles, and has improved the reaction velocity and the precision of locating.System bulk is little, in light weight, simple in structure and energy consumption is low, is convenient to assembling and uses.
