Abstract

The invention relates to an automatic sun tracking method and device, the method adopted is similar to the working principle of a sundial and comprises the following steps of: vertically arranging a pointer in the centre of a disk, using the shadow projected by sun to measure the position of sun, namely, detecting the position and direction of the shadow on the disk, and enabling the disk to rotate towards a direction opposite to the shadow to make the shadow finally disappear on the disk when the pointer points to the sun and the disk faces the sun. By the simple method, the sun can be automatically tracked. Moreover, an automatic sun tracking device is provided based on the method, wherein an upper, a lower, a left and a right solar panels are arranged at the front face of the disk; since the projected shadow may cause a voltage difference between two panels in bilateral symmetry or in longitudinal symmetry, once the state is detected by a detector, the orientation of a tracker is adjusted to make the shadow on the disk disappear, and at the same time, the symmetrical panels have no voltage difference, a motor stops rotation, and the disk faces sun; and thus, sun tracking is realized. The sun tracking device is simple in principle, skillful in structure, completely unmanned, high in tracking precision, and can be widely used in the development and the utilization of solar energy.

Description

technical field [0001] The invention relates to a light source detection and tracking method and device, in particular to a sun automatic tracking method and device in the technical field of solar energy development and application. Background technique [0002] With the development of the economy and the progress of the society, the traditional non-renewable energy sources such as coal, oil, and natural gas are increasingly scarce, and finding new energy sources has become an urgent issue facing mankind. Solar energy is a clean and renewable new energy, which is favored by more and more people. The development and utilization of solar energy will become more and more extensive, and it will become one of the important energy sources for survival. Accurate sun tracking is an important prerequisite to ensure the utilization of solar energy. Sun tracking is to use the sun tracking device to make the sunlight always enter the surface of the solar receiver vertically, so as to en...
