摘要

我国的农业正在向现代化、规模化、智能化发展。温室大棚作为现代农业生产中不可缺少的部分，对温室环境的有效管理能提高温室作物生产效率和农民经济效益。温室环境的湿度、温度、光照强度等因数对温室作物的生长有很大的影响。针对温室控制的需要，设计了一个基于无线传感器网络的温室控制系统。该系统通过分布在温室区域内的大量传感器节点采集信息，数据以Zigbee无线传送方式发送至汇聚节点。汇聚节点通过GPRS网络与远程服务中心通信，同时汇聚节点能接收远程服务中心发出的控制命令，控制部署在温室的控制节点，进而调节温室各参数达到合适要求。 关键词： 无线传感器网络，温室，ZigBee技术

Abstract Abstract

China's agriculture is to modern, large-scale, intelligent development. Greenhouse an indispensable part of modern agricultural production, the effective management of the greenhouse environment can improve the efficiency of greenhouse crop production and farmers' economic benefits. Greenhouse environment, humidity, temperature, light intensity and other factors on the growth of greenhouse crops have a great impact. A greenhouse control system based on wireless sensor network is designed for the needs of greenhouse control. The system collects information through the sensor nodes distributed in the greenhouse area, and the data is sent to the sink node in ZigBee wireless transmission mode. The convergence node communicates with the remote service center through the GPRS network, and the collection node can receive the control commands issued by the remote service center to control the control nodes deployed in the greenhouse, and then adjust the greenhouse parameters to meet the requirements. The system has the advantages of low cost and convenient deployment.
