Based Embedded System Mount Automatically Find The Star System

On the basis of astronomy, an MCU-based and an ARM-based automatic starfinder system for equatorial are designed. In this dissertation, the astronomical observation fundamentals and methods are introduced. In addition, the hardware and software designs for these two solutions are explicated. Traditionally, in order to find the object star, the observers have to operate the astronomical telescope manually. The embedded system design is adopted to drive the equatorial, and the hardware and software designs of the Philips' P89C51RD2-based system and SAMSUNG'S S3C44B0X-based system are finished, so that the system can automatically go to and trace the object star.This dissertation consists of six chapters. The first chapter introduces the classification of the starfinders, compares the automatic starfinder technology home and abroad and points out the significance and background of this project, so that the objective and task of this study are presented. In the second chapter, the astronomical theory element refers to the design is presented. In the third chapter, the overall scheme of the system and the automatic star tracing and finder technology that concerns the design are presented. The fourth chapter describes the designs of the hardware and software of the P89C51RD2-based system, explains the system functions and manipulation, and puts emphasis on the ISP function and database programming ADO technology. In the fifth chapter, an ARM-based system is introduced, including the hardware and software implementation, the keyboard and step motor extensions and the EMGUI programming technology. The last chapter gives a summary and prospect of the two solutions.
