摘要: 本文结合物联网思想和多种无线传输技术设计了一种多功能智能家居系统.设计的系统由感知层、网络层和应用层三部分组成.感知层设备包括智能门禁、环境参数检测和家电控制,该层各设备均
支持Gigbee协议通信.网络层包括Gigbee网络、控制终端和全球移动通讯系统/通用分组无线服务网络.控制终端与前端感知设备之间通过星型拓扑结构的Gigbee网络通信,前者作为协调器,后者作为普
通半功能节点.应用层通过手机和全球移动通讯系统网络实现与用户的交互.当感知层设备检测到出现异常时,会通过Gigbee网络将异常信息发送至控制终端,终端再通过全球移动通讯系统网络将信息发
送至用户手机.用户也可向控制终端发送短消息以实现对家电或安防设备的远程操作.由于全部采用无线通信,且全球移动通讯系统网络是我国覆盖面最广、最稳定的无线公网,因此本系统的安装为一便、无需
布线,即使在偏远地区同样能提供可靠服务.
