单兵作战系统中嵌入式GIS研析.pdf

南京理工大学硕士学位论文单兵作战系统中嵌入式GIS的研究摘要目前,信息战被认为是未来战争的主要作战样式。在信息战下战场必将是数字化的战场。因此,各国都在研究单兵作战系统,(GIS)功能是非常必要的。针对此背景,结合GIS、嵌入式Linux、Q'r/Embedded、路径寻优等技术,本文旨在开发一个具有自主知识产权的、安全的、无后门的嵌入式GIs,应用于单兵作战系统。本文研究了嵌入式GIS及其相关技术,对IAnux下开发嵌入式GIs的大致流程进行了研究和探讨。本文在嵌入式Linux操作系统上采用QT/Embedded作为图形用户界面(GUI)设计工具,设计了系统的GUI,在此基础上实现了嵌入式GIS的空间数据管理、地图显示、信息标注等部分功能模块。另外,本文还对路径寻优进行了研究,分析了原始Dijkstra算法及直线优化Dijkstra算法的原理,并设计了实现算法的数据结构。整个系统的设计运用面向对象编程思想,采用纯C++语言来编程实现,具有良好的移植性和通用性。关键词:单兵作战系统,嵌入式GIS,嵌入式Linux,QT/EmbeAded,路径寻优, Dijkswa算法 Abstract 硕士论文 Abstract Nowadays,information warfare isconsidered asthechieffightiIlg form offuture the Information warfare,the battlefield would became di百￡, inorder todlllance bat caDabililies andsurvivabilityof individual-soldier on the futuredi百tal battlefield,eachconmry isdoing some research on individual-soldier verynecessary tointegrateGeographic InformationSystem(GIS) forindividual- 011thisbackground,with bination of sometechnologies such asGIS、Embedded Linux、QT/Embedded、Path—finding and SO Oll,this thesis aims tode’rdop a safeEmbedded GIS withindependent intellectual property right and without Embedded GIS will be used in individual—soldierfighting system.
