The utility model content
The purpose of the utility model is the deficiency to above-mentioned technology, and a kind of fuzzy control, the asynchronous tracking automatic tracking rotation device to light is provided.
For achieving the above object, the technical scheme that the utility model adopted is:
A kind of automatic solar energy tracking device based on fuzzy control comprises base support, back shaft and solar panel, and its key is: also comprise fuzzy controller; The input end of said fuzzy controller is connected with optical sensor; First output terminal of this fuzzy controller is connected with first motor, and second of this fuzzy controller has been failed end and has been connected with second motor, and said first motor is fixed on the said base support; On the output shaft of first motor, driving gear is installed; The follower gear that is meshed with said driving gear is installed on said back shaft, and said second motor is fixed on the web member, and this web member is installed between back shaft and the solar panel; On the output shaft of second motor, be connected with screw pair, the other end of this screw pair is fixed on the said base support through screwing nut.
In fuzzy controller, be solidified with corresponding fuzzy control software; Fuzzy controller is gathered the situation of change of sun light intensity through optical sensor; Through comparing with the fuzzy control table that different time solar incident ray and earth geography position (longitude and latitude) are worked out in the variation of azel angle; After fuzzy operation is handled, send control signal to first motor and second motor, through the rotation drive corresponding mechanism action of first motor and second motor; Thereby the adjustment at travel direction angle and the adjustment of elevation angle, realize to the sun from motion tracking.
In order to make optical sensor sense sun light intensity signal better, said optical sensor is installed on the said solar panel, and the sensitive surface of this optical sensor is parallel with the side to light of solar panel.
In order to simplify the internal control algorithm of fuzzy controller, to be convenient to control signal and to carry out motor-driven, said first motor and second motor are permanent magnet DC motor.
In order to reduce energy dissipation, said fuzzy controller is that 6 ° of said first motors of control and second motor rotate with the stepping angle.That is to say, when the angle of sunray off-vertical solar panel reaches 6 °, just once adjust, thus realize to solar azimuth from motion tracking.
The remarkable result of the utility model is: the utility model is simple in structure, and it is convenient to implement, and can obviously improve dynamic performance, improves antijamming capability, avoids maloperation, increases reliability of operation; Select the stepping angle of the each adjustment of 6 ° of conducts for use, can reduce energy consumption, increase the sun power utilization ratio to greatest extent.
