摘要
针对智能家居系统存在布线难、功耗大、后期装修费用高等问题,结合IEEE 802.15.4e标准设计了一种无线自组织、终端自适应网络。同时,针对不同类型终端设备,设计了定时-外部中断休眠和定时-接收端发起这两种低功耗模式。以无线射频芯片CC2430为核心,搭建了一个基于IEEE 802.15.4e的自组织网络。通过上层界面、智能终端等对传感器节点进行环境、体征的实时监控及下行控制,使智能家居网络可以稳定、低功耗地运行,从而满足现代智能家居的实际应用需要。该方法对现代智能家居网络设计具有一定的指导意义。
In smart home systems, complex wiring or cabling, large power consumption, and high costs of post-renovation are very common. Combining with IEEE 802. 15.4e standard, the wireless self-organizing terminal adaptive network has been designed. In accordance with different types of the terminal devices, the timing-external interruption sleep mode and the timing-receiving end launching low power consumption mode are designed. With wireless RF chip CC2430 as the kernel, the self：organizing network based on IEEE 802.15.4e is built. Through the upper level interface and intelligent terminal, etc. , real time environment and sign monitoring for sensor nodes, and the downlink control are conducted. Thus, the smart home network can he operated stably with low power consumption for satisfying practical demands of modem smart home. The method possesses certain guiding significance to network design of modem smart home.
