基于MMA7455的跌倒检测和报警系统

Fall Detection and Alarm System Based on MMA7455

跌倒是老年人意外伤亡的首要原因,老年人跌倒后不能马上救治更是延误了最佳的抢救时间。基于此,本文提出了一种基于三轴加速传感器的老年人跌倒检测和报警系统。三轴加速传感器MMA7455可以获得老人运动数据,本文通过分析日常活动和跌倒的特征,设计出跌倒检测算法。报警模块使用android手机端,通过百度地图提供的定位和地址反解析功能,可以向家人和医院发送精准的报警数据。

Falling is one of the main factors that cause of accidental death in elderly people. The elderly people can not get timely treatment would miss the best rescue time. To face this problem, this article presents a fall detection and alarm system using a tri - axis accelerometer. Since the M MA7455 can capture elderly people＇s motion data, it designs fall detection algorithm by analyzing the feature of daily activities and fall detection. The alarm system uses android mobile terminal based android system. By location and location parsing provided by Baidu Maps, the terminal will send accurate information to family and hospital after falline.
