Abstract: Most home networks achieve wireless coverage based on WiFi and ZigBee,but these networks are sometimes unevenly covered due to wireless network devices with different configuration,and too many wireless network devices may lead to high-radiation energy.Aiming at these problems,this paper proposes a cooperative smart home network architecture based on Controller Area Network(CAN) and Bluetooth network,which is divided into backbone network and terminal network,and implements the prototype system.The backbone network is built by CAN,and the terminal network is set up by Bluetooth network.Experimental result shows that the system implemented by the proposed architecture has the advantages of wider coverage,higher communication quality and lower energy radiation,which can effectively support the application requirements of green home network.

摘要： 目前家居网络大多基于WiFi和ZigBee等进行无线覆盖,但由于家庭无线路由器的配置不同,网络可能覆盖不均匀,并且过多的无线网络设备会导致辐射能量过高。为此,提出一个基于控制器局域网(CAN)和蓝牙网络的智能家居协同网络架构,并进行原型系统实现。该架构包括家庭骨干网络和末端网络,网络骨干部分利用CAN搭建,末端网络通过蓝牙网络搭建。实验结果表明,利用该架构实现的系统具有覆盖范围广、通信质量好、无线通信能量辐射低的优势,可满足绿色环保的家庭网络应用要求。
