摘要

针对老年人的保健需求,本文设计了一种基于CC2431无线定位系统和SCA3060三轴加速度计的跌倒检测室内定位系统。CC2431定位引擎的定位算法基于RSSI值。盲节点会同时采集自身和参考节点的RSSI值,然后通过输入相应的环境参数对倒下的老人进行定位。三轴加速度计通过收集X、Y、z轴加速度计来判断老年人跌倒的方向和水平。当加速度超过某个阈值时,将向盲节点发送信号以定位位置并发出警报。

Design of smart home monitoring system based on ZigBee
For the health-care needs of the elderly people, a fall detection indoor positioning system based on CC2431 wireless positioning system and SCA3060 tri-axis accelerometer is designed in this paper. CC2431 location engine positioning algorithm is based on the RSSI values. The blind node will collect the RSSI value from both itself and the reference nodes and then locate the fallen elderly people by entering the corresponding parameters of the environment. The tri-axis accelerometer can determine the elderly fall direction and level by collecting X, Y, Z-axis accelerometer. When the acceleration exceeds some threshold, a signal will be sent to the blind node to locate the position and send alerts.
