摘要
针对田域环境面积大,有线组网方式成本高,布线困难等问题,提出了一种以ZigBee无线传感网络技术为核心的田域环境监测系统,并给出了节点能量优化方案。该系统包括信息采集部分和数据接收部分。信息采集部分由田域环境里布置的终端节点、路由器节点和协调器节点组成,终端节点和路由器节点负责采集空气温湿度,土壤电导率等参数,协调器节点负责汇聚信息。数据接收部分由网关服务器与手机、电脑组成。重点阐述了数据采集部分每层节点的硬件与软件设计,节点能量感知应用还有监测软件开发。试验结果表明:使用了能量感知方法和能效优化方案的网络,生存期最长,传送了更多的数据。系统的设计开发可为精细农业的发展提供数据支持。
Generally the size of farmland is large. It is high cost and poor flexibility to use wired network. Aiming at this situation, a farmland environment monitoring system by using the ZigBee wireless sensor network technology as the core and a scheme on node energy optimization are presented. This system includes two parts： the information collection and the data storage. The information collection consists of end-node, router-node and coordinator-node. Parameters such as temperature, humidity and soil electric conductivity are measured by end-node and router-node. Coordinator-node is responsible for collecting datum. The data storage consists of server and computer. The experimental result shows that the network which uses energy aware and energy efficiency method can live longer and send more data. This monitoring system may provide data support to the development of precision agriculture.
