同幅双速跟踪成像CCD相机NiosⅡ控制软件的设计

Design of a Control Software for a CCD Camera with Dual-Speed Tracking Imaging on Same Frame

介绍了同幅双速跟踪成像CCD相机对控制软件的设计要求,描述了该控制软件的设计思想及其基本结构,重点介绍了相机管理与控制模块和数据上传模块的设计方法与过程,包括如何对相机硬件进行控制的一些技术细节,给出了系统测试的结果,并对调试中出现的问题进行分析。

In order to observe moving objects（ such as satellites, space debris, and asteroids）and still objects（such as stars）at the same time by a single CCD camera, we develop a novel CCD imaging technique named as Dual-Speed Tracking Imaging on Same Frame（DSTIS）. As the analog circuit and digital controller of the camera have been made, what is needed is a software to control the camera. In this paper we present the design requirements of the camera control software, describe the design ideas and basic structure of the software, with the emphasis on the method and process of the design of the camera control module and the data upload module. These include the detailed methods for controlling the analog circuit. We finally present some test results and analyze problems that were encountered during the debugging .
