All-whether high-precision sun tracking control system

Abstract

The invention discloses an all-whether high-precision sun tracking control system, which comprises a base, a support, a sunlight sensor, a speed reduction actuating mechanism and a controller. The base is used as a carrier for the whole system. The support is mounted on the base and a plurality of condensers are arranged on the support uniformly. The sun sensor capable of collecting data of sunlight intensity and sun position is mounted at the edge of the support. The speed reduction actuating mechanism is mounted between the base and the support and used for controlling action of the support. The controller controlling movement of the speed reduction actuating mechanism is mounted on the base and electrically connected with the sun sensor. Besides, the sun sensor consists of right-angle prisms facing the east, the south, the west and the north, a photosensitive diode and infrared transmission glass, and thus high-precision tracking is realized according to the principle of critical angle of total reflection. In addition, the controller can be guided into the corresponding light control and time control tracking modes by the photosensitive diode regardless of the sun, and accordingly all-whether high-precision sun tracking is realized.

Problems solved by technology

Compared with conventional energy sources, solar energy also has many advantages such as large total energy, long-term durability, universality, and no pollution.

[0003] In the existing technology, there are many ways to track the sun, but there are not many practical and stable applications and promotions. The reason is that system cost and reliability, stability and tracking accuracy are the biggest problems restricting solar tracking applications: reliability and cost are both difficult to meet

Also useful hydraulic structure is more complex, the price is higher, and the current sunlight sensing control system uses a spherical lens to sense the focal spot or a photosensitive diode or a four-quadrant photodetector, etc., the structure is complex, the cost is high, the sensing error tolerance angle is small, and the tracking accuracy is not good. advanced defects

[0004] In addition, in complex weather conditions, since the sunlight sensing angle range that the sun tracking sensor can sense is small, it may cause misjudgment and deviate beyond the sensing angle range, and the sun cannot be found.
