【摘要】 随着信息技术的发展,传统的农业监测方式已不能适用人们对信息获取的需求。无线传感器网络(WSN)是一种以数据为中心的自组织网络,网络节点部署密集;网络拓扑结构具有自组织性与自调整性,可适应于复杂的地理和恶劣变化的环境下。本文以基于茶园旱情监测的无线传感器节点系统的设计与实现为研究背景。首先,介绍了无线传感器网络的体系结构和特点。其次,设计实现了茶园旱情检测节点系统,并以太阳能电池板和锂电池作为电源模块,有效的保证了节点的生命周期。第三,在深入分析和研究Tiny0S操作系统的基础上,编写了模块驱动程序,并将TinyOS应用到本文所设计的节点系统,实现了高效组织和管理硬件资源。最后,对茶园旱情监测无线传感器节点系统的功能和性能进行了测试,并在广东省农科院英德茶园基地部署节点,进行了组网实验,采集了环境温湿度和土壤水分含量的数据,验证了在茶园组网的可行性,对进一步研究利用WSN技术进行茶园旱情在线检测奠定了基础。更多还原

【Abstract】 With the development of information technology, the traditional way of monitoring agriculture can not be applied to people’s access to information needs. Wireless sensor network (WSN) is a self-organizing network based in data, of which nodes deployed densely; Network topology with a self-organizing and self-adjusting, and can be adapted to the complex and adverse changes in the geographical environment. In this paper, the background for the study is the design and implementation of monitoring system of tea plantation drought with wireless sensor node. First, it introduced the architecture and characteristicsa of a wireless sensor network. Second, it designed a tea garden of drought-node system, and this system used solar panels and lithium batteries as a power supply module, which guaranteed the life cycle of the node effectively. Third, on the basis of in-depth analysis and research Tiny0S operating system, we programmed the module drivers, and TinyOS this article would be applied to the design, which achieved a highly efficient organization and management of hardware resources. Finally, we tested the functionality and performance of this system, deployed nodes at the Academy of Agricultural Yingde tea base of Guangdong Provincial, carried out the experiment, collected environmental temperature and humidity and soil moisture content data and verifyed the feasibility of network. All those laid the foundation of further study of WSN technology in tea garden of drought-online measurement.更多还原
