文档介绍：摘要
近年来,随着电子技术,信息技术的蓬勃发展与广泛应用,农业温室技术也在向自动化、信息化方向发展。本文从农业生产的实际情况出发,对控制网络与信息网络的融合技术进行了研究,,结合起来,的温室远程监控系统。
远程技术是控制技术借助现有的信息网络延伸其控制范围的监控技术,本文分析了控制网络同信息网络主要的融合方式,并在此基础上选择RS-485作为现场总线,远程传输数据构成远程监控系统。
针对温室地域上的分散分布、不易铺设专用线路等特点,的融合。
在分析了温室环境远程监控系统需求的基础上,设计了一种适合对大量温室进行管理的监控系统;同时,考虑到系统向信息化智能化发展的趋势,设计了适合同信息管理系统相结合的网络结构。
基于研究和温室实际需要,本文设计并实现了一基于GPRS和Web技术的温室环境远程监控系统,该系统具有C/S和B/S两种结构,在Web服务器上架设运行,系统采集的数据为农业科学研究提供了便利条件。

ABSTRACT
With the development of the technique in electronics and information in recent years, the technique in agricultural greenhouse are using more and more automation and information techniques. Based on this, this thesis researches on the amalgamation technique between work and work. For actual requirement of agricultural research, greenhouse field work and are connected in the greenhouse remote control system based on .
Remote control technique results from the spread work control. The approach of broaden the work ing from the existing work. This thesis analyzes the realization mode of amalgamation work and work and on basis of this, RS-485 is picked as field bus to the remote monitoring system with connection with .
Aimed at the characteristics of decentralization and having some trouble with laying the work in the greenhouse field, GPRS munication module is selected to realize the amalgamation between greenhouse field work and .
On analyzing the requirement of greenhouse environment remote control system, this thesis designs a system to manage large numbers of greenhouses. And considering the development trend of information and intelligence, this thesis designs work bined with information management system.
Based on the research above, this thesis develops an environment remote monitoring system for greenhouse with GPRS and Web. This system has C/S and B/S twofold modes, and operates on Web Server. The system makes it easier for agricultural science researchers to do research in
greenhouse.
