摘 要
隨著經(jīng)濟(jì)條件的發(fā)展，人們對(duì)于日常生活的衣、食、住、行的要求越來(lái)越高。食品方面，市場(chǎng)對(duì)各種各樣的反季蔬菜水果、綠色無(wú)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(duì)于解決日益增長(zhǎng)的市場(chǎng)需求和傳統(tǒng)技術(shù)無(wú)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(guò)對(duì)國(guó)內(nèi)外溫室系統(tǒng)的分析和研究，設(shè)計(jì)出一種溫室智能監(jiān)控系統(tǒng)。
所設(shè)計(jì)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(wú)線傳感器網(wǎng)絡(luò)三部分。
整個(gè)系統(tǒng)是基于B/S架構(gòu)設(shè)計(jì)的，客戶端可以是任何一臺(tái)連入因特網(wǎng)的PC機(jī)，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(huà)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(tái)。嵌入式Web服務(wù)器主要實(shí)現(xiàn)兩個(gè)功能：首先，與無(wú)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(duì)其下達(dá)控制命令。其次，通過(guò)Internet與客戶端通信，實(shí)現(xiàn)本地?cái)?shù)據(jù)的遠(yuǎn)程共享。
無(wú)線傳感器網(wǎng)絡(luò)由三種節(jié)點(diǎn)組成：協(xié)調(diào)器節(jié)點(diǎn)、路由節(jié)點(diǎn)、終端節(jié)點(diǎn)。協(xié)調(diào)器節(jié)點(diǎn)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(yùn)行。路由節(jié)點(diǎn)負(fù)責(zé)傳遞信息。終端節(jié)點(diǎn)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(lèi)傳感器節(jié)點(diǎn)的設(shè)計(jì)均遵從了低功耗的設(shè)計(jì)思想。
在對(duì)系統(tǒng)軟硬件設(shè)計(jì)的基礎(chǔ)上，課題還對(duì)針對(duì)周年生產(chǎn)的溫室進(jìn)行了控制算法的設(shè)計(jì)。針對(duì)周年生產(chǎn)的溫室需要適應(yīng)溫度跨度大的特點(diǎn)，設(shè)計(jì)一種基于模糊控制算法和切換控制思想的一類(lèi)經(jīng)濟(jì)、節(jié)能的控制方案。相對(duì)與在設(shè)計(jì)完成后，利用MATLAB/Simulink仿真工具對(duì)控制方案進(jìn)行仿真，驗(yàn)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
