【搭載強大嵌入式處理器的 IoT 裝置，電池總是不夠用～～～】

物聯網 (IoT) 終端裝置的典型特徵是功耗極低、體積小巧的裝置，可能採用自行供電或設計為只要一顆鈕釦型電池便能持續運作多年；但其實，USB 與乙太網路等有線資料連接方式，也能為目前要求最嚴苛的 IoT 終端裝置提供有效便利的供電解決方案。

有些搭載強大嵌入式處理器的 IoT 裝置——需要在本機處理資料以降低網路延遲和提高隱私，或只是降低最終成本，它們可能有一個機械子系統，像是具備平移傾斜變焦 (PTZ) 功能的攝影機，很容易又會增加整個系統的功率需求。在這些產品應用中，小電池無法滿足系統的最高功率需求，或是提供的電量並不足以滿足所需的執行時間，而需要定期更換電池。

然而，若終端裝置採用有線 USB 或乙太網路連線功能，設計人員就能利用各自的供電功能。乙太網路供電 (PoE) 和 USB Power Delivery (USB-PD) 使用相同的電纜進行供電與資料傳輸，可避開與電池及交流電源有關的缺點。USB 供電與 PoE 都有既定的標準，且以低電壓進行供電，終端用戶在操作裝置時也較為安全，可利用現成的 DC-DC 轉換器、穩壓器和保護裝置來克服電源方面的難題。

2002年，憑藉獨特敏銳度察覺到電子業界需求，《COMPOTECHAsia電子與電腦》於中國大陸取得《COMPOTECHChina》月刊發行權，為初到海外發展及當地讀者出具最具前瞻性且中肯的觀察，具有相當影響力，也成為一流國際大廠競相展示研發心血的首選。 2006年，有鑑於網路環境日趨成熟，《COMPOTECHAsia電子與電腦》再度領先同業，首創線上視頻平台CTOV (COMPOTECH Online Video)。自此，成為整合紙本、網站、電子報及線上視頻的全方位媒體。 2016年，為貫徹市場應用及開發技術的連結並擴大群眾基礎，陸續展開 Facebook、Twitter、LinkedIn 等社群平台經營。「就市論勢、就勢論市」是我們的信念。我們將於每週一、三、五下午在 FB 分享生活中隨處可見的科普知識，以平易近人的方式，用不一樣的角度觀察市場趨勢和技術走向，並不定時穿插轉載網路精彩佳作或趣聞。記得設為「搶先看」哦！ “COMPOTECHAsia/ China” issue on 8th monthly. It is the dependent media which focuses on electronic industry situation, end user market, and technology trend. The monthly magazine has become the main channel to get professional information for engineers, purchaser, R&D employees and decision-making management. We perceived the demand of electronic industry and strive to get the distribution rights of “China Edition” in Mainland China in 2002. It gives a lot of prospective and proper observation for the overseas workers and local readers. Gradually, COMPOTECH is getting to be the powerful. Nowadays, COMPOTECH is the first-choice platform for the first-class firms to display their R&D results. Furthermore, in 2006, we were ahead of our competitors to build the CTOV platform (COMPOTECH Online Video) due to the mature internet environment. Since then, COMPOTECH has become the integrated media. For having a thorough knowledge of market applications and technology migration, as well as expanding the base of the masses, we begin to manage the Facebook, Twitter and LinkedIn etc. in 2016.

智能系統設計／應用工程師、產品／專案開發主管、元器件／零組件／準系統採購者的交流園地，於每週一、三、五下午分享【科技應用取向】的趨勢議題。
