智能家居系统网络大致可分为外部网(因特网)、内部网(ZigBee自组网)和家庭网关。其中,家庭网关是核心部分,它负责家庭内部网络和外部网络的连接和协议转换。下面介绍内部网,这里的内部网就是ZigBee自组网,根据家庭布局采用树状或者星形网络拓扑。ZigBee自组网包括各个终端节点,这些节点配合继电器控制家庭中各种电器开关、温湿度传感器等家庭中需要被监控的设备对象,从而达到远程监控功能。从通信的
Smart home system network can be broadly divided into external network (Internet), intranet (ZigBee ad hoc network) and home gateway. Among them, the home gateway is the core part, which is responsible for the connection and protocol conversion of the intra-home network and the external network. The following describes the internal network, where the internal network is ZigBee ad hoc network, according to the family layout using tree or star network topology. ZigBee ad hoc network includes each terminal node, these nodes cooperate with the relay to control all kinds of household electrical switches, temperature and humidity sensors and other devices that need to be monitored in order to reach the remote monitoring function.
