以CAN-Bus設計飛行與量測資料顯示系統

鑒於近年來小型飛行器與無人載具盛行，但其航電系統卻普遍不足，且國內輕航機之飛行儀表現多為傳統模擬型儀表，大多無氣候感測、導航定位等相關飛行電腦，導致飛行載具於飛行時之安全性大為減低。另外，隨著飛行載具之航電機能越來越被重視，功能也越來越多，使得飛行載具上配線繁雜，檢修不易。因此，本文提出以控制區域網路匯流排(Controller Area Network-Bus，CAN-Bus)設計應用於飛行載具之飛行與量測資料顯示系統。CAN-Bus是一種多主方式的串列通訊匯流排，結構簡單，節點有優先權不互相衝突，抗電磁雜訊干擾，且有利於輕航機上之配線與檢修。以CAN-Bus設計飛行與量測資料顯示系統，將能達成有效率且易於操作、維修、整合與監控之多功能飛行載具航行電腦。

In view of recent years, the small aircraft and unmanned vehicles are more popular, but their avionics systems are insufficient, and the light aircraft flight instrument is mostly without climate sensing, navigation and other related flight computer, leads to aircraft in flight safety be greatly reduced. In addition, with the flight vehicle can be taken with more features, the flight vehicle wiring and, maintenance are not easy. Therefore, this paper proposes a control area network bus ( Controller Area Network-Bus, CAN-Bus ) design and can be applied to aircraft flight and display system. CAN-Bus is a major way over the serial communication bus, and has the advantages of simple structure, node priority that is not in conflict with each other. The CAN-Bus base design for flight and measurement data display system, will be able to achieve the efficient and easy way to operate, repair, integrate and monitor for aircraft navigation.
