近數十年來，數位航電匯流排新技術之研發，已經成為航電系統不可或缺的角色，並藉以提升通用航空飛機的性能，而控制區域網路(CAN)在許多應用上皆有極佳性能。隨著電子技術的發展，微控制器也成為控制和監測的重要核心元件，本論文把此技術與觀念植入以控制區域網路為基礎的航電系統中。
本論文建構與設計一個適合小型飛機數位航電的控制區域網路匯流排系統；實驗尋求以微控制器與數位資料匯流排相互結合的應用方式，透過目前已整合CAN Bus的C8051F060微控制器，建立分散式的監測系統，此系統有著低成本、簡單監測線路、體積小的優點；本實驗設計以C8051F060為核心的硬體電路板當成節點，每個節點在應用上都可以接到真正的儀器或感測器或者模擬訊號源，飛行員可以透過電子飛行儀表(EFIS)了解目前飛行位置與航機本身的狀況。

In recent decades, new technology developments on digital avionics data bus system have become important and necessary infrastructure to enhance future general aviation aircraft system. Controller Area Network (CAN)-based data bus technology has presented its function capability for such applications. With the development of electronic technology, the microcontroller becomes the important core in control and monitor. This thesis implements CAN-based avionics system with above technology and conception.
This thesis presents a prototype fabrication and verification for digital avionics for small aircraft systems; the experiment searches the application that microcontroller has union of data bus. The experiment establishes the dispersed monitor system by using C8051F060 microcontroller which integrates CAN bus. The avionics system has advantage of low cost, simple electronic wire and small volume. The electronic board with C8051F060 is to be the node, and which node can connect real sensor or simulate signal source. Pilot can know the information of location and airplane situation via electronic flight instrument system (EFIS).
