摘要

依國家發展委員會報告指出，在民國82年台灣己成為高齡化社會，推估將於民國107年邁入高齡社會，民國115年邁入超高齡社會，根據衛生福利部新聞公告，65歲以上老人事故傷害死亡原因第二位就是老人跌倒(落)。所以關於老人跌倒在近年來己成為是一個不可忽視的問題，本論文提出一套加速度偵測系統，具有偵測到跌倒後提醒的功能。
在此篇論文中我們使用意法半導體所開發的STM32F302R8以及ADI所開發的三軸加速度傳感器ADXL345並透過其演算法來實現跌倒偵測功能，在使用者跌倒時可立即偵測到並發出警訊，以期待長者跌倒時能快速讓周邊的人知道，並能立即給予救援。

According to the report of the National Development council, we became an aging society in year 1993, and estimated that it will enter the aging society in year 2018. In year 2026, we will enter the hyper-aged society.
According to the news of the Ministry of Health and Welfare, fall is the second to cause of death for the age more than 65 years old. So the fall of the elderly in recent years has become a problem which cannot be ignored, this paper presents a set of acceleration detection system with the fall detection and warning functions.
In this paper, we use the STM32F302R8 developed by STMicroelectronics and the ADXL345 developed by ADI to realize the fall detection function through its algorithm, which can be detected and issued immediately when the user falls, and people around can quickly know and give the relief.
