摘 要
随着经济条件的发展,人们对于日常生活的衣、食、住、行的要求越来越高。食品方面,市场对各种各样的反季蔬菜水果、绿色无公害产品、转基因产品的需求日益增大,温室技术对于解决日益增长的市场需求和传统技术无法满足这种需求两者之间的矛盾有非常重大的意义。本文通过对国内外温室系统的分析和研究,设计出一种温室智能监控系统。
所设计的温室智能监控系统主要包括客户端、嵌入式Web服务器、无线传感器网络三部分。
整个系统是基于B/S架构设计的,客户端可以是任何一台连入因特网的PC机,并且不需要安装任何专用的软件就可以查看温室智能监控系统的监控画面。
嵌入式Web服务器采用ARM7TDMI-S微控制器LPC2210为硬件核心,μCLinux操作系统为软件平台。嵌入式Web服务器主要实现两个功能:首先,与无线传感器网络通信,接收其采集的环境数据并分析、处理,以及对其下达控制命令。其次,通过Internet与客户端通信,实现本地数据的远程共享。
无线传感器网络由三种节点组成:协调器节点、路由节点、终端节点。协调器节点负责与嵌入式Web服务器通信,协调自己所在的星型网络的运行。路由节点负责传递信息。终端节点根据所接受到的调节命令控制终端调节器,调节环境参数。各类传感器节点的设计均遵从了低功耗的设计思想。
在对系统软硬件设计的基础上,课题还对针对周年生产的温室进行了控制算法的设计。针对周年生产的温室需要适应温度跨度大的特点,设计一种基于模糊控制算法和切换控制思想的一类经济、节能的控制方案。相对与在设计完成后,利用MATLAB/Simulink仿真工具对控制方案进行仿真,验证了其有效性。

Abstract
With the development of economic conditions, people’s demand of everyday clothing, food, shelter become increasing too. As foods, the market of off-season fruits and vegetables, green pollution-free products, and GMO products are biger day after day, however,greenhouse technology just solve the conflict between the growing market demand and the reality that traditional technologies can not meet this demand .Based on analysis and research the domestic and international greenhouse system, subjects design a greenhouse intelligent monitoring system.
The intelligent monitoring system designed for the greenhouse include client, embedded Web server, wireless sensor networks three parts.
The whole system is based on B/S structure, the client can be any PC connected to the Internet witch does not need to install any special software and you can view the intelligent monitoring system for monitoring the greenhouse picture.
Embedded Web server using LPC2210 ARM7TDMI-S microcontroller core for the hardware,and μCLinux operating system software for platform. Embedded Web server to achieve two main functions: First, communicat with wireless sensor network and received the environmental data it collection then analysis, processing, and give it control command. Secondly, communicate with clients through the Internet, to share local data of the remotly.
Wireless sensor network consists of three nodes: the coordination node, routing node, terminal node. Coordinator node is responsible for communication with the embedded Web server, and coordinate the star network where they operations. Routing node transmission the information. Terminal node may adjust the terminal regulator according to the command and control to regulate the environmental parameters. Design of various types of sensor nodes follow a low-power design.
On the basis of hardware and software design, subjects also carried out for the annual production of greenhouse control algorithm design. For annual production of greenhouse need to adapt to the characteristics of a large temperature span, the design based on fuzzy control algorithm and switching control of a class of economic thought and energy control
program. After the design is complete, using MATLAB / Simulink simulation tool to simulate the control program to verify its effectiveness.
