摘要
智能家居工作在智能电网的用电域,旨在提供直接与用户互动的交互环境。采用低速无线个人局域网的家庭自动化网络,可应用于家庭的照明、安防以及家电、设备等的自动控制。文章通过对家庭自动化系统架构和业务源特性的分析,构建了基于IEEE802.15.4标准的OPNET无线网络仿真模型,分析了时隙CSMA/CA机制和保证时隙机制的网络特性,评估了不同节点数和网络负载对时延和功耗的影响,对家庭自动化系统网络的参数设置和节点部署有一定的参考意义。
Smart Home work aims to provide an interactive environment in the customer domain of smart grid. Home Area Network adopts Low-Rate Wireless Personal Area Networks （LR-WPANs） to realize the automatic control of lighting system, safety system, smart appliances, smart devices, etc. This paper discusses the architecture of Home Automation, constructs the OPNET simulation model of wireless network based on IEEE802.15.4 standard, analyzes the performance of synchronous mechanism of the slotted CSMA/CA and the Guaranteed Time Slots, and evaluates the number of nodes and network load＇s impact on the energy consumption and end-to-end delay, which has some reference values on the parameter settings and deployment of nodes in home automation network system.
