Vision-based rotating light tracking type solar panel device

Abstract

The invention relates to a vision-based rotating light tracking type solar panel device, which comprises a base (4) and a solar panel (1) mounted on the base (4), and further comprises a horizontal rotating mechanism, a vertical pitching mechanism, a visual tracking mechanism and a controller. The horizontal rotating mechanism is mounted on the base (4) and can make rotating motion in the horizontal direction relative to the base (4), the vertical pitching mechanism is movably mounted at the top of the horizontal rotating mechanism and can make pitching motion in the vertical direction relative to the horizontal rotating mechanism, the solar panel (1) is fixed to the vertical pitching mechanism, the visual tracking mechanism is mounted on the solar panel (1) and used for tracking the sun center, and the horizontal rotating mechanism, the vertical pitching mechanism and the visual tracking mechanism are all connected to the controller. Compared with the prior art, the structure is simple and reliable, and the power generation effect is high.

Description

Technical field [0001] The invention relates to a solar panel device, in particular to a vision-based rotating chasing solar panel device. Background technique [0002] The incoming solar radiation (sunlight) from the Earth in the upper atmosphere received 174 petawatts (PW). Approximately 30% of the solar energy is reflected back to space, while the remaining solar energy is absorbed by clouds, oceans and land. The solar energy spectrum on the earth's surface is mostly distributed in a small part of the near ultraviolet, all visible light, and near infrared spectrum. [0003] The solar energy absorbed by the earth’s atmosphere, oceans and land is approximately 3,850,000 EJ per year. In 2002, there was more solar energy in one hour than the world used in one year. The biomass energy obtained from photosynthesis is about 3000 EJ per year. The technical potential of biomass energy is 100-300 EJ / year. The amount of the sun’s energy reaching the surface of the earth is so huge tha...

Problems solved by technology

[0007] However, the traditional solar tracker has some disadvantages: due to the functional limitations of the solar tracker, its installation environment is relatively harsh, and it needs to withstand the variable outdoor temperature, wind, frost, rain and snow. The traditional light intensity sensor is relatively simple and only has the sensor function. When the temperature changes, the measurement accuracy will change greatly

The light-following strategy of traditional solar trackers is relatively simple, just relying on feeling to give a deflection angle or light-sensitive position, so the best light-following effect cannot be achieved

The light sensor used in the traditional solar tracker does not have a linear relationship with the light intensity, but only an approximate linear relationship, so it has a great influence on the measurement results
