電機與電子技術的發展，引領著航電系統快速地向前邁進。在許多的控制和監測系統中，微控制器一直都是重要的核心元件；而數位資料匯流排更是數位航電系統的骨幹，不同的資料匯流排具有不同的特性與適用的範疇。此兩者緊密的結合，將使航電系統能夠有更高層次的發展和更普及的應用。
在這論文中，提出一個已經使用於商業客機上的系統，即斷路器狀態監測系統；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C8051F040微控制器，建立分散式的監測系統；改善現有監測系統線路過於複雜的情況，以簡化航機線路的配置。藉由實驗的結果，驗證了這架構的可行性；這些成果將有助於微控制器在數位航電系統上，提供更即時與更有效益的應用。

The development of electrical and electronic techniques leads the avionic systems to move forward speedily. In many of the controlling and monitoring applications, the microcontroller functions as the core unit of importance continuously. The digital data bus is the backbone of digital avionics; the different data buses have particular characteristics and applicable scope. The close combination of microcontrollers and digital data buses will be able to improve further developments and more widespread applications upon the technology of avionics.
This thesis proposes a practice used on the commercial airplane, namely the circuit breaker status monitoring; seeking a appropriate manner that integrates microcontroller with digital data bus, established the distributed monitoring system by means of the C8051F040 microcontroller with Controller Area Network bus connectivity; amend the complex wiring routing in the original architecture, to reduce the amount of wiring routed in the aircraft. The analysis of results conforms that the implementation is a satisfyingly feasible way; and these achievements will be helpful for the microcontrollers provide more instantaneous and effective applications in avionic systems.
