隨著再生能源及無線網路技術的應用越來越廣泛，傳統的監督控制與資料擷取(SCADA，Supervisory Control and Data Acquisition)系統應用所提供監控主機的電源線佈署，以及監控末端至中央監控中心間資料線佈署，可以被取代利用。本論文主題「電源自給式之無線遠端監控與資料擷取工業電腦」，整合太陽能再生能源以及無線網路技術，讓放置在戶外空曠的監控主機，仰頼太陽能所產生的電源，利用無線網路技術作現場監控，並利用GSM手機通訊模組以及Zigbee無線模組，免去實體佈線而將資料傳回遠端的中央監控中心。由於太陽能供電系統的不確定，本論文也深入探討能源電力採集的多寡，倘若電力不足時，依監控末端資料採集狀況，分為四種資料採集策略，依照這四種資料採集策略，而決定系統的用電時機，使得監控末端點所採集的資料能夠24小時持續性的收集，回傳給中央監控中心。也因為太陽能供電的不穩定，資料的保存也是相當重要的，資料從監控末端點、監控主機最後到中央監控中心，針對資料的保存方法，提出利用虛擬EEPROM讓短暫的電源消失時，資料能夠安全的存放，使資料不被遺失。

With the increasingly wide range of applications for renewable energy and wireless network technology, the conventional SCADA (Supervisory Control and Data Acquisition) system that employs power cable deployment for the remote terminal units and data line network between the monitoring end point and SCADA host center can being replaced. This study examined “Solar Powered Industrial Computer for Wireless Supervisory Control and Data Acquisition Applications”. The integration of renewable photovoltaic energy and wireless network technology enables a remote terminal units located in an open outdoor area to conduct on-site monitoring with photovoltaic power through GSM mobile phone communication module and Zigbee wireless module, transmitting data back to SCADA host center without physical wiring. Considering the unreliability of photovoltaic power systems, this thesis also makes an in-depth study on the availability of photovoltaic energy. In the event of power shortage, one of four data acquisition strategies is deployed depending on data acquisition conditions at monitoring end point. The strategy that is deployed will decide on a power utilization schedule in order to ensure 24-hour continuous data acquisition at monitoring end point and transmission of data back to the SCADA host center. Moreover, the unreliability of photovoltaic energy also makes data preservation crucial. Virtual EEPROM is proposed as a specific data preservation method for storing information that is transmitted from monitoring end point and remote terminal units back to SCADA host center, enabling safe data storage and no data loss during short-term power failure.
