嵌入式地理信息系统硬件平台设计
|
摘要
本文根据军用战术无线信息终端的立项要求，提出了一种基于嵌入式处理器系统的地理信息系统硬件平台设计方案，依据项目需求和在对国内外相关技术方案比较的基础上，确定了平台的体系结构、模块组成和器件选型；同时详细给出复合视频转换模块、触屏控制部分以及数字RGB、模拟RGB和TV三种LCD显示接口的设计方法，最后给出了样机的测试结果和结论。
This paper puts forward a design of the geographic information system hardware platform ,according to the project-building demand of the military tactics wireless information terminal. And the designed platform is based on the embedded processor system. The system structure of the platform, the makeup blocks and the apparatus selection are given in the paper according to the project demand and the comparison among relative projects. This article introduces the design of the complex video transform block, the touching-screen control block, and the display interfaces which consist of digital RGB mode, analog RGB mode and TV LCD mode . Finally the paper gives the test result of the model machine and the conclusion.
