【摘要】 在无线传感器网络(WSN)的应用中,物理信息与位置信息关联才具有实际的运用价值,由此无线传感器网络节点的位置信息至关重要,是传感器网络研究的难题及热点。本文以导航系统的为应用背景,在自主研究开发的一套无线传感器网络信息采集平台上实现了节点位置信息获取、处理及应用的导航系统的设计开发。首先,通过设计带有全球定位系统(GPS)节点的绝对定位和基于接收信号强度指示(RSSI)测距的无线传感器网络节点间相对定位,实现了满足室内外定位需求的无线定位系统;然后结合无线传感器网络系统开发了一套人机交互的地理信息系统(GIS),实现了节点位置信息的在电子地图上的处理及直观显示;最后,应用地理信息系统的位置信息资源设计了具有路径搜索、轨迹实时追踪功能的路径搜索系统,从而实现了一个完整的导航系统。整个导航系统的设计穿插在无线传感器网络平台的传感器节点系统、数据收集系统、数据存储和分析系统的设计中。在无线定位方面做了大量的针对性测试工作;在处理地理信息系统中电子地图的每个细节上也做了对应的工作,实现了无线传感器网络平台与地理信息系统的结合;经过改进最短路径算法的实现,在地理信息系统上实现了快捷的导航路径查询。最终本文在完成了系统全部设计和制造的基础上,以校园为实践模型进行了系统整体测试和使用,取得了良好的预期效果,证明了本系统的实用价值。更多还原

【Abstract】 It has the practical value for the Wireless Sensor Network (WSN) application only when the physical and location Information associated with each other. So the location-specific information is essential for WSN technology and it is also a hot research area for it. In this paper, it has introduced a self-developed information collection platform with the node location acquisition, processing and application to realize design and development of navigation system.In this paper, it first introduced how to design a wireless location node. The node has the function of the absolute location with the geographic information system (GPS) and the relatively location with the received signal strength indicator (RSSI) that the node has received. It meets the wireless location needs indoor and outdoor. Next the geographical information system (GIS) developed above the node is introduced. It has realized the map information processing and display directly to the user. Last the paper overviewed the whole system. It has the function of path search and track.WSN sensor node system, data collection system, data storage system and data analysis system design were introduced throughout the design of whole navigation systems. A lot of test work is done for the position function. Appropriate work has been done to complete the combination of WSN and GIS. Speedy path-search function is realized in GIS though improvement of the location algorithm. Finally, based on the design and manufacture of the whole system, a test case in campus as practice model was implemented for the system’s functions as a whole and a good expectant result are met in the test which proves its practical value of this system.更多还原
