Research Of Dynamic Solar-tracking Technology Based On High-precision Algorithm

In the contemporary society where energy crisis happens frequently, thereforesolar energy are attracting pupils for its clean and huge energy. To harness solarenergy efficiently it is necessary to employ the highly precise dynamicsolar-tracking technique. Simple algorithms were often employed in some studiesto approach the basic tracking with worse precision.Based on the High-precision sensors, the position of the sun trackingalgorithms were studied.The current energy status was introduced and the research status andapplication of the solar-tracking technology were analyzed. The basic principle ofthe solar motion was introduced, and the technology of astronomical sun-tracking,electro-optical sun-tracking and their combination were elaborated. According tothe high-precision algorithm design dynamic tracking system, the technology andapplication of the GPS was studied and high-precision dynamic tracking algorithmsbased on GPS, photo detector dynamic tracking algorithm and technique ofmechanic power were analyzed.The software of the improved algorithm wasachieved. And the interface of the high-precise algorithm based on the sensors wasdemonstrated by the software of the QT design. The running results was presentedexplicitly.The1st ring of the city of Hefei was chose as the observation spot, andthe GPS based algorithm accuracy was analysed with the calibration of NASAofficial calculator. The algorithm was verified to meet the need of application andwill provide much valuable reference for the consequent research and application.The tracking system studied here has attributes of high precision, dynamic,all-weather capability, comprehension and self-adjusting. It is of great practicalsignificance in highly precise solar-tracking, utilization improvement,measurement of solar radiation and meteorological parameters and monitoring ofsandstorm.
