摘 要
近年來，世界人口逐漸增加，耕地面積日益減少，環(huán)境惡化，自然災害頻發(fā)。但是市場對食品的數(shù)量和品質(zhì)要求卻日益提高。多層次立體栽培，大規(guī)模生產(chǎn)高品質(zhì)、無污染作物的植物工廠是解決上述矛盾的重要途徑。為滿足周年連續(xù)生產(chǎn)，植物工廠環(huán)境控制技術成為研究重點。
溫濕度是影響植物生長的關鍵因子。本文主要針對植物工廠環(huán)境控制技術的溫濕度采集和自動監(jiān)控，結(jié)合嵌入式技術、無線通信和網(wǎng)絡技術，設計了一種適合植物工廠的溫濕度遠程監(jiān)控系統(tǒng)。整個系統(tǒng)基于B/S架構設計，以嵌入式Web服務器為核心，ZigBee無線傳感器網(wǎng)絡為溫濕度采集終端，具有成本低、效率高、簡便實用的優(yōu)點。
嵌入式Web服務器以ARM7為硬件核心，通過連接CC2430無線通信模塊接收ZigBee無線傳感器網(wǎng)絡采集并傳送的溫濕度數(shù)據(jù)；為了實現(xiàn)數(shù)據(jù)的遠程查看，針對ARM7微處理器移植了μCLinux操作系統(tǒng)和Boa服務器，以TCP/IP協(xié)議棧為基礎，采用CGI接口實現(xiàn)動態(tài)網(wǎng)頁。用戶可以通過瀏覽器訪問嵌入式Web服務器，查看植物工廠溫濕度數(shù)據(jù)，授權用戶還可以根據(jù)數(shù)據(jù)做出判斷，發(fā)送控制命令，調(diào)節(jié)植物工廠內(nèi)溫濕度值。
溫度是影響植物生長最重要的環(huán)境因子，在完成系統(tǒng)軟硬件設計的基礎上，為了實現(xiàn)對溫度的自動控制，首先，建立了植物工廠溫度模型；其次，針對植物工廠多層立體栽培和溫度梯度變化的特征，從節(jié)能角度出發(fā)，提出了一種溫度場控制和模糊神經(jīng)網(wǎng)絡控制相結(jié)合的溫度控制方案；最后，對控制系統(tǒng)進行仿真，結(jié)果驗證了設計方案的有效性。

關鍵詞 植物工廠；無線傳感器網(wǎng)絡；遠程監(jiān)控；嵌入式Web服務器；溫度場；模糊神經(jīng)網(wǎng)絡










Abstract
In recent years, the world population increase gradually and the agricultural acreage decreases year by year. What’s more, environment degradation and more and more natural disasters. However, Public awareness and demand for food has risen. Multi-level stereo cultivation and mass production high quality pollution-free food could solve the contradictions. In order to meet the annual continuity of production, environmental control technology becomes the focus.
The temperature and humidity is the key factor of the effect on the plants growth.Combined with embedded technology, wireless communication technology and network technology, the paper study environment data acquisition and automatic monitoring of plant factory environment control system, and design remote monitoring system which is suitable for plant factory greenhouse. The whole system based on B/S framework, and embedded web sever as the core, ZigBee wireless sensor network as the temperature and humidity acquisition terminal. Low cost, high efficiency, easy and pratical are also the system’s advantages.
The embedded web server use ARM7 microcontroller as hardware core, which connected to CC2430 wireless communication module to receive humidity data collected by ZigBee wireless sensor network. In order to remote view, transplanting μCLinux operation system and Boa server to ARM7, TCP/IP protocol for the foundation, CGI application procedure for dynamic webpage. User could visit embedder web server and view humidity data by browser.The authorized user could send control instruction by analyzing data to realize the regulation of temperature and humidity.
The temperature is the most important environmental impact factor on the plants growth. Based on hardware and software, in order to realize automatic control of temperature, First, establish plant factory temperature model; Second, Put forward the control scenario combining temperature field with fuzzy neural network from energy saving angle according to the features which contain multilayer and temperature gradient change of plant factory; Finally, The simulation result verified the effectiveness of the designed algorithm.

Keywords Plant factory; wireless sensor network; remote control; embedded web server; temperature control; fuzzy neural network
