基于Zigbee技术的智能家电系统设计.docVIP

摘 要 这篇文章运用无线技术进行组建室内家电控制网络系统，让不同的家庭设施(如照明、家电和室内环境等)通过网络进行互联，体现无线技术的方便与安全。 本文首先分析了国内外智能家电系统技术的现状，然后针对智能家电系统存在的布线困难、造价较高、构复杂等其他问题，提出运用基于Zigbee无线通信技术的智能家电系统的设计方案，进行无线数据的采集和传输。 通过对智能家电的网络分析、对比和研究，运用星型网络建立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设计并构成一种低成本，灵活性高、可广泛运用的Zigbee无线智能家电网络。接下来，介绍智能家电控制系统软件部分的实现。运用Microchip提供的Zigbee协议，再结合具体要实现的功能进行编程。 关键词：智能家电；Zigbee；PIC18LF2420；CC2420； Abstract This article uses the wireless comunication technology to carry through the Home electrical appliances network, which makes all kinds of home facility (such as illuination, home electrcal and home environment etc.) interconnect, to reflect the conveience and security of the wireless comunication technlogy. First, throgh the analyze the prsent 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.
