本文討論設計一組以微機電系統為基礎之飛行資訊量測組件，包含慣性及大氣數據量測組件與磁羅盤量測組件兩套次系統。慣性及大氣數據量測組件所提供之量測功能包含三軸加速度; 三軸角速度; 壓力; 壓差與溫度等資訊;磁羅盤系統則負責提供三軸磁場大小之量測。兩系統均以Microchip PIC 單晶丹微控制器來負責成測器訊號之擷取與轉換，並將訊號傳送至電腦接收端以進行後績之訊號分析與處理。慣性與及大氣數據量測組件之訊號傳送介面為RS-232 '磁羅盤則為USB 介面。本設計完成飛行資訊量測組件之軟; 硬體整合與訊號傳遞之編解碼過程，並完成功能驗證。 This paper summarizes the development of a MEMS-based flight information system, It includes an inertial and air data measurement unit and an electronic compass unit. The inertial and air data measurement unit provides the capability for three-axis accelerations, three-axis angular rates, airspeed, altitude, temperature, and angle of attack measurements. The compass system is used to measure the magnitude of the external magnetic fields. A Microchip PIC micro-controller is used in each measuring unit to perform data acquisition and deduction and to transfer the results to the host system for further analysis and processing. The inertial and air data measurement unit uses the RS232 serial port to interface with the host system while the compass unit uses the USB bus. A hardware-software integrated, function tested real system is accomplished in this design.
