摘要
目前,温室农业正在我国蓬勃发展,每年温室面积都以几百万公顷的速度增长,温室农业已经成为我国农业中不可替代的产业,对我国经济的增长也有重大贡献,然而与我国农业大国极不相称的是我国在温室农业方面,技术落后,尤其是在温室环境监控方面,这极大的限制着我国温室农业的发展,因而,研究温室监控系统显得越来越重要。
本文设计了基于无线传感器网络的温室监测系统,该系统主要由终端节点、路由节点和网关节点组成,终端节点主要作用是采集温湿度数据并且无线传输数据,硬件采用了ATMEGA 2420无线通信模块、SHT15温湿度传感器;路由节点主要作用是转发由终端节点上传的温湿度数据和由网关节点下发的命令,在硬件方面,与终端节点相同,也采用了ATMEGA 2420无线通信模块、SHT15温湿度传感器;网关节点主要作用是管理终端节点和路由节点、创建无线网络以及对上传的温湿度数据进行显示、存储和远程发送,在硬件方面,该节点采用了以S3C24lO芯片为核心的平台,包括键盘模块、液晶显示屏模块、GSM模块、U盘存储模块。

ABSTRACT
Currently, greenhouse agriculture is China's booming, annual greenhouse area growth rate of tens of millions of hectares of greenhouse agriculture has e irreplaceable in China's agricultural industry, have made significant contributions to China's economic growth, however, a big agricultural country with China's vastly disproportionateChina in greenhouse agriculture, technological backwardness, especially in the greenhouse environment monitoring, which greatly limit the development of greenhouse agriculture in China, and thus to study the greenhouse control system has e increasingly important.
Designed greenhouse monitoring system based on wireless works, the system is mainly divided into two modules, the first module is a wireless work is posed by the wireless sensor node, the node hardware used ATMEGA 128L microcontroller, CC2420 munication module, SHT15 temperature and humidity sensors, the software portion of applications specifically for wireless works, TinyOS operating system and the nesC language, the temperature and humidity data acquisition and wireless transmission function; the second module is the gateway node, the node hardware used to with chip S3C24lO as the core platform, including the keyboard module, LCD module, GSM module, U disk storage module, the software part of the application of the most
