摘　　要：经过对人体跌倒中所经历状态的分析,设计了一种基于检测加速度变化来判断跌倒的远程跌倒报警仪。这种跌倒检测报警仪的工作原理是通过对佩戴人发生跌倒时身体姿态的变化所引起的传感器3个轴上的加速度变化来监测人体是否跌倒。当检测到人体跌倒后,跌倒检测报警仪自身发出声光报警信号,并自动将跌倒报警的信息通过GPRS以短信或拨打电话的方式通知监护人员,同时通过IEEE 802.15.4e无线的方式将报警信息发到智能家居的远程监控网页,进行远程报警提示和报警信息的存储。Based on the analysis of human body falling state, a kind of fall detection alarming apparatus is designed based on the change of acceleration. The working principle is through detecting the wearer when he falls in the change of body posture caused the 3-axis＇ s acceleration change to moni- tor the human body is falling. When the body fall signal is detected, the fall detection alarming apparatus audible alarm signals, and the alarm information automatically through GPRS module are both sent to the other family members＇ phone. At the same time, the alarm information is send to the smart home server as IEEE 802.15.4e wirelessly, and is forwarded to the smart home remote monitoring page.
