    Abstract: 本論文研究目的為設計一可將電表所顯示的用電量資訊傳回電腦並做分析,再將用電量的相關資訊透過電腦分析給使用者知道的裝置,而因為是透過Arduino開發板以及外接的小型相機來擷取相關的資料的關係,所以使用者也可以自己根據不同的需求來加入其他功能,並不會受到廠商硬體規格的限制,而軟體開發的部分因為是採用Arduino的關係,一般的使用者也可以自行撰寫相關的功能,透過這樣的關係讓一般的使用者或開發者可以大大的掌握自己的技術跟想法,而不再局限於市售廠商制式的軟硬體規格。

    目前在市面上這種相關的電表用電資訊辨識裝置,大部份都是採用高價位的運算晶片且程式都已經預先寫好燒錄進去,因此功能有限,無法再針對我們自己想要的部分特殊功能再另外加入或修改,且因為採用的晶片價格較高,所以整體裝置的總價格相對高昂,從數千至數萬元不等,而如果因為有其他需求還要額外的購買另外的配備來做結合,整體預算相較於本研究所設計出的裝置高昂許多。

    本研究論文透過Arduino Uno Rev3開發板來做為電表資訊辨識裝置的控制板,透過板子控制相機進行電表資訊的擷取接著再透過預先在電腦寫好的辨識程式進行用戶的用電量分析等功能,而Arduino的相關語法淺顯易懂且網路上有很多其他開發者免費公開分享的資料可以學習,且價格便宜好入手,讓一般的使用者可以不再被市場所販售的產品局限功能而進行客制化。
    ;The purpose of this research is to design an Arduino-based device that can receive a power meter′s usage data for further analysis. By using the Arduino Uno Rev3 development board and the JPEG camera, users can add customized features such as the ones for this research and integrate them into a single device. One significant feature of our device is that it can recognize regular text or numbers that are displayed on any power meter because of reusing the OCR (optical character reader) library. Currently, similar devices on the market are more expensive and do not allow users to develop new functions. Hence, if users want to add more functions, they need to pay for the extension components or plugins, which undoubtedly increase the overall cost. Various font types and characters, which were displayed on power meters and captured by the JPEG camera, were used to test the correctness of our device functionality. The results showed that it can continuously send actual meter readings to a computer for further analysis.
