摘要
提出了一个可以进行远程报警的无线跌倒监控系统。跌倒检测是通过佩戴在人体的终端设备获取人体运动时产生的加速度信号,然后通过跌倒算法对数据进行处理识别。终端识别跌倒信号后,通过ZigBee无线网络将信号传输到网关,网关通过发送AT指令到SIM300模块来发送报警短信到监护人手机上。实验结果表明,系统可以100%检测到人体跌倒,使医护人员及家属在5s内收到跌倒报警信息。
This paper presents a system of wireless fall-monitoring with remote alarm. The fall-detection technology is based on the signals of acceleration during a fall and processed by fall-algorithm. When an accidental fall is detected, an alarm message will be sent to the monitor＇ s mobile phone through the ZigBee wireless network. The experiment results demonstrate that the system has a 100% accuracy of fall-detection, and the monitor can receive the alarm message within 5 seconds.
