基于嵌入式技术的舰船电子海图无线服务终端开发
|
摘要
电子海图系统和雷达系统是保障舰船安全航行以及作战能力的关键。为适应新形势下舰船对于电子海图使用的灵活需求,本文提出一种基于ARM11嵌入式系统和Wifi无线网络的舰船电子海图无线服务终端系统,对电子海图以及嵌入式系统进行基本介绍,详细分析了电子海图在μC/OS-II实时嵌入式操作系统上的绘制流程,并对嵌入式服务终端实现无线传输方案进行论证。本文提出的电子海图无线服务终端能够极大提高使用电子海图的方便程度,同时系统功耗小,适用性广,并且具有良好的稳定性。
Electronic chart system and radar system are the key to ensure the ship's safe navigation and combat capability. Ships in order to adapt to new situation for electronic chart using the flexible demand, this paper puts forward a kind of based on embedded system and ARM11 ship electronic chart of wireless Wifi network service terminal system, the electronic chart, and embedded systems is the basic introduction, detailed analysis of the electronic chart in μC/OS-II real-time embedded operating system on the drawing process,and the scheme of embedded wireless transmission service terminal. The electronic chart wireless service terminal proposed in this paper can greatly improve the convenience of using electronic chart, meanwhile, the system has small power consumption, wide applicability and good stability.
