摘　　要：针对农业低成本定位需求,设计了一种基于无线传感器网络的农业定位系统,系统由定位平台和定位节点两部分构成,其中定位节点包括锚节点和移动节点。定位系统部署完成后,首先各锚节点向定位平台发送包含自身位置、节点ID的数据包,定位平台建立网络拓扑图和数据链表;然后移动节点向所有锚节点发出定位请求,接收并存储各锚节点的RSSI值;最后定位平台采集移动节点与各锚节点通信的RSSI值,并应用定位模型确定移动节点的估算位置。试验表明,该定位系统具有简单易实现、定位效果好等特点。For the demand of agriculture low-cost localization,an agriculture localization system based on wireless sensor network was designed. The system is composed of localization node and localization platform. The localization node is composed of anchor nodes and mobile nodes. After system deployment,the data packet of node ID and location of each anchor node are sent to the localization platform to build the network topology and data linked list. And then the mobile nodes send the localization requests to all anchor nodes to receive and store RSSI values of each anchor node. Finally the localization platform is used to collect the RSSI values of mobile nodes and each anchor mode,and the localization model is used to determine the estimation location of the mobile nodes. The test results show that the system has the characteristics of easy implementation and good localization effect.
