伴随着电子信息技术的迅发展, 嵌入式系统已经在以光学和机械为导向的传统天文望远镜领域中发挥着越来越大的作用。以往的寻星过程需要观测者依靠手动调整天文望远镜，要求操作者有较高的天文知识，并且精度不高，尤其对于新手来说较为困难。本文根据天文学基础理论知识，结合实际需要，归纳设计了一套恒星位置计算方法，并基于MSP430单片机完成了自动寻星系统的开发，整个系统具有以下优点：操作方便、成本低、精度高。
本文首先概述了国内外自动寻星技术的背景和发展现状，结合目前实际，提出了自动寻星系统的现实意义，并由此提出了课题的具体研究内容。在第二章中，详细介绍了天球坐标系等基本的天文知识，阐述了天球坐标系间的换算以及时间计量系统。第三章介绍了系统硬件电路设计，详细描述了驱动电路和控制电路的设计、并详细介绍了MSP430单片机。最后一章则介绍了程序的设计，并成功完成调试和运行。21688

Title The design of the auto-star telescope
Abstract
With the rapid development of electronic information technology in the traditional optical and mechanical-based astronomical telescope field , the embedded system has been vigorously promoted and applications. The traditional star-searching process requires the observer to rely on manual adjustment of the telescope, which is complicated and imprecise, especially difficult for entry-level amateur astronomers. According to the theoretical knowledge of astronomy combined with the reality of equatorial mount, the thesis introduce an algorithm of star-searching with high-precision and the development of auto star-searching system based on MSP430. The whole system has the following advantages: easy to operate, low cost and high accuracy. This paper outlines the background and development of the status quo of the auto star system at home and abroad , combined with the current reality, proposed the significance of auto-star system , and thus put forward specific research topics. In the second chapter , detailing the basic knowledge of astronomy celestial coordinate system , etc. , explained translation between different celestial coordinates and the time metering system . The third chapter describes the hardware circuit design of the system , a detailed description of the operating functions of the system , the drive circuit design , MSP430 MCU and functional module design based on it. The final chapter describes the program of the system , functions and features of the system are also summarized.
Keywords auto-star astronomical theory hardware circuit driver circuit MSP430
