    Abstract: 本文探討設計一個三軸之低成本的電子式飛機失事感測器。此失事感測器的主要功能為持續監視飛機飛行狀態,並在飛機失事之瞬間,自動送出警示信號給緊急定位信號發射器,發送飛機位置訊號,以縮短搜救的時間。失事成測器之桔心為微機電加速儀,利用PIC 單晶丹微控制器負責執行加速度信號擷取、分析及屆主動警示命令等動作。
    This paper discusses the design and implementation of a low cost three-axes electronic crash sensor for airborne application. The primary function of crash sensor is to continuously monitor the flying situation of air vehicle, and to engage the ELT system in the case of crash incident occurs. The core component of the crash sensor is the MEMS accelerometers. The data acquisition, reduction, and crash determination are accomplished using a low cost PIC microcontroller.
    The crash condition is determined based on vehicle acceleration and variation of velocity. A backup Li-Ion battery is incorporated into the system to prevent power shut down. A drop test is also developed and performed to investigate the characteristics of impact accelerations.
