Two applications systems were introduced to demonstrate the capabilities of FS. System of FS consists of hardware and software. Sensors such as soil moisture sensor, temperature and humidity sensors, water level sensor and IP camera and actuators such as relay and solid state relay were used to control the active/enactive of lamps, alarm, fans, motors and foggers, etc. manually or automatically based on predefined controlled algorithm. Related software was developed based on VB.Net platform and data measured of all sensors can be stored into a database and retrieved afterward. Two application systems were developed including exhibition stand for ornamental pot plants with Internet wise remote monitoring and control functions and controlled environmental growth chamber with Internet wise remote and local control capabilities on lamps. Thanks to the advanced of IT technologies, both systems introduced make the term ‘remote control’ with new meanings. Although, both examples demoed were focusing on Bio-industrial applications, we are quite sure that such system can find vast applications in many other fields.摘要 i ABSTRACT ii 誌謝 iii 目錄 iv 表目錄 vii 圖目錄 viii 第一章 緒論 1 1.1前言 1 1.2研究目的 2 第二章 文獻探討 3 2.1環境伺服器系統 3 2.2無線感測網路(Wireless Sensor Network) 7 2.3網路架構 11 2.4無線區域網路 15 2.4.1 802.11b 17 2.4.2 802.11a 18 2.4.3 802.11g 18 2.4.4 802.15 20 2.5感測器 21 2.5.1 AD590感溫IC 23 2.5.2 PT-100 28 2.5.3 含水率感測器 31 2.5.4 水位感測器 32 第三章 材料與方法 33 3.1系統架構 33 3.1.1硬體設計一 34 3.1.2硬體設計二 36 3.2 感測器元件 40 3.2.1土壤含水率感測器 40 3.2.2溫度感測器 43 3.2.3水位開關 47 3.3 PICNIC 50 3.4無線AP與IP 攝影機 60 3.5電源系統之整合 64 3.6負載與繼電器 68 3.7第三代系統 70 第四章 結果與討論 83 4.1系統說明 83 4.1.1 近端使用方式 83 4.1.2 遠端使用方式 84 4.2硬體線路配置 86 4.3軟體規劃與界面說明 88 第五章 結論與建議 91 參考文獻 94 附錄一 PICNIC 原廠提供之使用說明 963072320 bytesapplication/pdfen-US田間伺服器環境伺服器感測器遠端監控Field ServerSensorRemote monitoring and controlthesishttp://ntur.lib.ntu.edu.tw/bitstream/246246/52842/1/ntu-96-R93631020-1.pdf
