Abstract

The invention discloses an automatic sun tracking device and a control method, mainly solves the problems that a mono-shaft tracking method is large in tracking error although being simple in implementation, and a dual-shaft tracking method is complex in structure and larger in technical difficulty although being high in tracking precision, and provides an automatic tri-freedom-degree sun tracking device under a horizontal coordinate system. The device comprises a tri-freedom-degree moving platform on which a circuit part is mounted. The circuit part is formed by a main control module, a posture measuring module, a time module, a motor driving module, an optical signal detecting module, a data storage module, a communication module, a power supply module and a watchdog circuit. The main control module is used for the work of operation, processing, commanding, coordinating and managing of the whole equipment and is of a core part of the equipment. The automatic sun tracking device and the control method realize the automatic tracking on the sun, and have the advantages of reasonable product structure, stable circuit work, high efficiency, being less influenced by external conditions and the like.

Description

Technical field [0001] The invention relates to an automatic sun tracking device and a control method, in particular to an automatic sun tracking device with a three-degree-of-freedom sun tracking target in a horizontal coordinate system, belonging to the technical field of solar energy application. Background technique [0002] At present, the development and utilization of solar energy has attracted much attention, and how to improve the utilization rate of solar energy has become the focus of research. In addition to improving the conversion efficiency of solar energy equipment to light energy, tracking the sun is an effective means to improve solar energy utilization. According to experiments, the solar energy utilization rate of the equipment with automatic sun tracking is 35% higher than that of the fixed-angle equipment. Therefore, it is very necessary for solar energy equipment to track the sun in the development and utilization of solar energy. [0003] For the sun autom...
