摘 要
隨著經(jīng)濟條件的發(fā)展，人們對于日常生活的衣、食、住、行的要求越來越高。食品方面，市場對各種各樣的反季蔬菜水果、綠色無公害產(chǎn)品、轉(zhuǎn)基因產(chǎn)品的需求日益增大，溫室技術(shù)對于解決日益增長的市場需求和傳統(tǒng)技術(shù)無法滿足這種需求兩者之間的矛盾有非常重大的意義。本文通過對國內(nèi)外溫室系統(tǒng)的分析和研究，設(shè)計出一種溫室智能監(jiān)控系統(tǒng)。
所設(shè)計的溫室智能監(jiān)控系統(tǒng)主要包括客戶端、嵌入式Web服務(wù)器、無線傳感器網(wǎng)絡(luò)三部分。
整個系統(tǒng)是基于B/S架構(gòu)設(shè)計的，客戶端可以是任何一臺連入因特網(wǎng)的PC機，并且不需要安裝任何專用的軟件就可以查看溫室智能監(jiān)控系統(tǒng)的監(jiān)控畫面。
嵌入式Web服務(wù)器采用ARM7TDMI-S微控制器LPC2210為硬件核心，μCLinux操作系統(tǒng)為軟件平臺。嵌入式Web服務(wù)器主要實現(xiàn)兩個功能：首先，與無線傳感器網(wǎng)絡(luò)通信，接收其采集的環(huán)境數(shù)據(jù)并分析、處理，以及對其下達(dá)控制命令。其次，通過Internet與客戶端通信，實現(xiàn)本地數(shù)據(jù)的遠(yuǎn)程共享。
無線傳感器網(wǎng)絡(luò)由三種節(jié)點組成：協(xié)調(diào)器節(jié)點、路由節(jié)點、終端節(jié)點。協(xié)調(diào)器節(jié)點負(fù)責(zé)與嵌入式Web服務(wù)器通信，協(xié)調(diào)自己所在的星型網(wǎng)絡(luò)的運行。路由節(jié)點負(fù)責(zé)傳遞信息。終端節(jié)點根據(jù)所接受到的調(diào)節(jié)命令控制終端調(diào)節(jié)器，調(diào)節(jié)環(huán)境參數(shù)。各類傳感器節(jié)點的設(shè)計均遵從了低功耗的設(shè)計思想。
在對系統(tǒng)軟硬件設(shè)計的基礎(chǔ)上，課題還對針對周年生產(chǎn)的溫室進(jìn)行了控制算法的設(shè)計。針對周年生產(chǎn)的溫室需要適應(yīng)溫度跨度大的特點，設(shè)計一種基于模糊控制算法和切換控制思想的一類經(jīng)濟、節(jié)能的控制方案。相對與在設(shè)計完成后，利用MATLAB/Simulink仿真工具對控制方案進(jìn)行仿真，驗證了其有效性。

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.

Key words greenhouse intelligent monitoring; embedded Web server; wireless sensor networks; ZigBee
