基于嵌入式及ZigBee技术的老人居室环境监测系统

摘要

为及时获取独居、空巢老人的居住环境信息,防止老年人出现意外事故无法得到及时处理,设计了一种基于嵌入式和ZigBee技术的居室环境监测系统.系统通过ZigBee无线传感器网络采集室内的环境信息,并上传至基于Easpberry Pi的嵌入式网关,通过对采集数据的分析和处理,实现对室内环境、老人活动状态的预警预报.可通过Internet或GPES/3G网络,访问网关获取监测数据,实现远程监控.系统结构简单,扩展方便,部署灵活,操作简单,适用于老人居住环境监测.%For timely access to the living environment information of the elderly people living alone,preventing old people cannot get timely treatment when an accident happens,an environment monitoring system for intel igent home is designed. The system acquires environmental data through the ZigBee wireless sensor network and transmits them to the embedded gateway which based on Easpberry Pi.If some environmental parameters exceed the set value,the system can alarm in ad-vance.The remote users can access to the gateway and get the monitoring data by Internet or GPES/3G network.
