基于Zigbee技术的智能家电控制系统设计 摘 要 首先，本文在分析了国内外智能家电系统技术现状，针对智能家电系统存在的布线难、造价高、结构复杂等问题，提出采用基于Zigbee无线通信技术的智能家电系统设计方案，进行无线数据的采集和传输。 通过对智能家电网络的分析、对比和研究，采用星型网络组建智能家电系统的内部网络；利用TI的射频芯片CC2420 Zigbee模块和Microchip的微控制器PIC18LF4620设计并构架成一种低成本，高灵活性、通用的Zigbee无线智能家电网络。然后，介绍智能家电控制系统的软件部分实现。利用Microchip提供的Zigbee协议，结合具体要实现的功能进行编程。 关键词：智能家电；Zigbee；PIC18LF2420；CC2420； The Design of Smart Home Electrical Appliances Based on Zigbee Technology Abstract This article uses the wireless communication technology to carry through the Home electrical appliances network, which makes all kinds of home facility (such as illumination, home electrical and home environment etc.) interconnect, to reflect the convenience and security of the wireless communication technology. First, through the analyze the present status from domestic to overseas contraposed the problem of hard-routing, high-cost, complex-structure existing in the Smart Home electrical appliances, and proposed a design options by adopting Zigbee wireless communication technology, for the wireless data of gather and transmission. This article on the smart appliance network analysis, comparison and research, the use of stars to form smart network appliance systems internal network; the use of TIs radio frequency chip CC2420 Zigbee modules and PIC18LF4620 microcontroller Microchip design and architecture into a low-cost, highly flexible, general-purpose network Zigbee wireless intelligent home appliances. And then, this article introduce the smart home appliances control system whose software to achieve, Microchip provides the use of the Zigbee protocol, combined with the functionality to achieve specific program.
