Development of High-Precision Solar Tracking System Based on 51 Microcontroller
In conventional solar tracking system design, optical tracking method and visual tracking method were mainly used. A machine is designed to track the sun automatically based on a CMOS camera, and a virtual software developement is developed by NI company. The sun’s azimuth and elevation are calculated through the relevant algorithm in real time, converted into the desired motor running pulses, and transmitted to 51 single-chip through the RS232. The motor rotation is controlled by the microcontroller to appropriate angle, so that the sun is always in the center of the spot position of the image. The experimental apparatus has a high tracking accuracy and good stability, the minimum tracking error can reach 0.002°.
