【摘要】 组合导航系统利用两种或两种以上的导航分系统提供多重数据,采用数据融合技术来获得最优的导航信息。在组合导航技术迅速发展的背景下,导航设备能否安全、可靠地运行成为评价其导航能力优劣的重要标志,然而现在大多数机构对组合导航的理论研究和实际研发并未有效地统一起来,同时也缺少对多元导航数据的实时显示和对导航设备性能的有效监测。基于以上考虑,本文以实际课题研究为依托,在深入研究了组合导航系统原理的基础上,设计了组合导航评价验证系统。按照设计需求,评价系统分为三大部分,即硬件平台的设计,数据采集系统软件设计和评价系统应用软件设计。论文首先介绍了系统的总体设计思路,详细阐述了系统的功能结构和软硬件设计方案；然后以philips ARM7-LPC2292处理器为硬件核心,进行了最小系统、串口扩展和A/D转换等主要模块的电路设计；接着实现了系统的软件设计,主要包括硬件设备驱动程序和评价计算机应用程序的开发,其中硬件设备驱动程序是在ADS 1.2 Code Warrior IDE集成环境下采用C语言来实现,而应用程序是在Windows操作系统下利用Visual 6.0 C++开发工具来设计；最后,系统采用Access2003创建后台数据库,前端则利用ADO技术来实现对数据库的访问。该评价系统进行了软硬件调试和相关模拟实验,运行结果表明系统可以采集多元导航数据,并在对数据进行解析和处理后完成真值数据和被测数据的输出比较和实时显示,能够有效监测导航设备的性能,满足设计需求。更多还原

【Abstract】 Integrated navigation system has two or more navigation subsystems to provide multiple datas, and can get the best navigation information by the use of data fusion technology. With the rapid development of integrated navigation technology, whether it can operate safely and reliably is an important symbol of quality evaluation of navigation equipment.However, most institutions make their researches on integrated navigation with theory and practice separated, and the normal development system also lacks the real-time display technology of multiple navigation datas and the effective monitoring of navigation equipment performance.In this paper, after doing thorough research on system development process,an evaluation system for the performance of integrated navigation based on a deep theory research is designed. According to the design requirements, the design of system is divided into three parts. There are hardware development, software design with data acquisition system and the procedure program system.Firstly,the holistic considering of system design is introduced.System function,seheme design and configuration are described in details. Then, the hardware design of syetem based on ARM processor LPC2292 is discussed, which is mainly composed of reduced system,serial-port expansion and A/D converting. What’s more, the software platform with data acquisition system and application software system is developed. The drivers of hardware devices make use of C to develop in the ADS1.2 Code Warrior IDE,and the application software is carried out in the use of Visual 6.0 C++. Finally,the system establishs the database in the use of Access2003.and can visit the database by a method of ADO.The hardware-software codesign and debugging of the system are realized, and the test results show that the system can collect multiple navigation datas. At the same time, it can measure the performance of navigation equipment through data comparison and real-time display. At present, the system can meet the requirements of production.更多还原
