Embodiment Construction

[0020] The present invention will be further illustrated below through an implementation case.

[0021] The invention uses an ARM7 microprocessor and its peripheral circuit as a controller, combined with a solar bracket designed with a biaxial structure. In the bracket structure, the worm gear motor 3 fixed on the outer edge of the pillar is used to drive the support shaft 8 to rotate in the horizontal direction, thereby driving the solar panel 2 to rotate in the horizontal direction; and the lifting motor 4 is used for Drive the rotation of the solar panel 2 in the vertical direction. Under the combined effect of the two, the rotation of the solar panel 2 at any angle within the range of 270 degrees horizontally and 120 degrees vertically can be realized. (See figure 2 )

[0022] The light intensity sensor is installed in the center of the plane of the solar panel, and a light intensity collector cylinder 6 with a cylindrical shell is provided, and a photoresistor is resp...

Abstract

The invention relates to a sunflower-type solar energy generating system. In the system, a photoresistor is adopted as a light intensity induction part, an ARM7 microprocessor and a peripheral circuit thereof are taken as controllers, and the light intensity induction part and the controller are combined with a solar energy support designed into a biaxial structure, thereby realizing that a solar energy battery board faces the direction of the maximum solar illumination intensity all along so that the effective generated energy is greatly increased. After one-day tracking is completed, the system automatically restores to a state of waiting the morrow sun to rise, thereby realizing diurnal cycle operation. Moreover, the system is integrated with a liquid crystal display (LCD) screen and a storage battery charging and discharging circuit utilizing a maximum power point tracking (MPPT) technology, thereby breaking the mode that the traditional solar energy generating system comprises a plurality of independent units. Such design reduces the volume and the weight of equipment and moreover reduces the operation power consumption of the whole system.

Description

technical field [0001] The invention relates to the field of automatic control, especially the technical field of embedded computers. Background technique [0002] In recent years, photovoltaic power generation has developed rapidly in the world. In 2007, the newly installed solar energy capacity in the world reached 2826MWp, of which Germany accounted for about 47%, Spain accounted for about 23%, Japan accounted for about 8%, the United States accounted for about 8%, and my country accounted for less than 1%. In 2007, a large amount of investment in the solar photovoltaic industry chain was concentrated on the improvement of new production capacity. In addition, the loan financing amount of solar photovoltaic enterprises increased by nearly 10 billion US dollars in 2007, making the scale of the industry continue to expand. In 2008, the global photovoltaic market increased to 5.5GW, among which Spain ranked first by region and Germany second. In 2008, the total amount of g...
