Auto sun-tracking system of solar energy gathering device

Abstract

The invention belongs to the technical field of solar energy application, in particular relates to an automatic sun tracking system of a solar collector. The system consists of a motor which drives the solar collector to track the sun, a mechanical transmission mechanism and a tracking control circuit which controls the mechanical transmission mechanism to operate; the system is characterized in that a GPS receiver arranged on the solar collector and an attitude sensor are used for outputting the signals of the position, the orientation, and the like, of the collector to a microprocessor; the microprocessor outputs control signals to the motor, so as to control the mechanical transmission mechanism to drive the solar collector to face the sun directly after working out the difference value of the orientation of the collector and the position of the sun. The system can realize the accurate all-round sun tracking in real time by adopting the GPS location finding technique without the influence of weather and environment, and is suitable for the solar collector which has the fixed position on the earth or the solar collector which is arranged on the moving car body and a transocean vessel to track the sun.

Description

technical field [0001] The invention belongs to the technical field of solar energy application and relates to an automatic solar tracking system of a solar energy concentrator. technical background [0002] As a kind of clean energy, solar energy is inexhaustible and inexhaustible, and it is the new energy with the most development potential. The energy released by the sun per second is about 16×1023KW, and the total amount of solar energy reaching the earth’s surface in one year is equivalent to about 1.892×1019 million tons of standard coal, which is 10,000 times the proven reserves of major energy sources in the world. my country's solar energy resources are very rich, but at present, the utilization of domestic solar energy is far from enough. This is mainly due to some weaknesses in solar energy resources: low density of sunlight, intermittent irradiation time, and constant changes in spatial distribution. Because of these weaknesses, the utilization rate of solar en...

Problems solved by technology

When there is intermittent cloudy weather, rainy weather, or even just clouds temporarily covering the sun in the sky, the sensing unit of this type of tracking method cannot reflect the changes in the sun's light. When the rain or clouds pass, the sun may have deviated larger angle

This tracking method requires the sensing and detection unit to be able to respond to changes in the sun's rays in a wide range, which is difficult to implement. The current tracking methods are only suitable for tracking the sun with fixed concentrators on the earth, and are not suitable for The moving car body and the solar concentrator on the ocean-going ship track the sun
