本文以四顆單晶片為核心處理器，並搭配飛行時所需之感測器與航電儀器，架構成無人飛行載具的飛行電腦暨航電系統，並使之能連結地面監控軟體站。飛行電腦包含了飛行資訊的收集、處理，以及資料的傳輸、通訊，其中更重要的部分在執行決策並即時作出判斷與下達指令使飛行載具動作。本文針對單晶片的工作方式與硬體架構做一探討，並提出以I2C(Inter-Integrated Circuit)通訊介面作為單晶片間溝通的橋樑。 以Microchip公司所出產之MCU PICR系列單晶片PIC18F2550為飛行電腦的核心，負責資料的整合與決策，PIC16F88和PIC18F2550分別擔任GPS與Data Link的資料緩衝區，還有一顆PIC16F88為飛行模式手動或自動的切換。依本文所完成之航電系統裝置所需，設計與製作一無人飛行載具為實驗平台並實際應用之。此套航電系統裝置的完成，更在成本的花費上大幅的降低，在所需體積空間上，也較具優勢。 實驗平台主要的設計出發點為修改現有之無人飛行載具的氣動力外型，以求更佳的飛行性能。 An avionics system which contains four microchips and relevant sensors is studied. The system performs not only the functions of flight information collection, processing, data transmission and communication but also the judgment and decision of unmanned aerial vehicle (UAV) movement. The topic of this paper is the interface of I2C (Inter-Integrated Circuit) for microchips communication and discussion of function and framework for microchip. One of four microchips PIC18F2550 that is produced from Microchip Corporation PICR series MCU as flight computer’s core, handling the integrated and decision of flight information. The data buffer of GPS and Data Link are PIC16F88 and PIC18F2550. Other PIC16F88 is the changing of flight pattern manual or automatic. For the need to verify the avionics system, designing and manufacturing a vehicle. The completion of avionics system advantages not only reduction spent of cost but also volume of size. The design of experiment platform is the modifying of aerodynamic shape that on have for better flight performance.
