摘  要
本文采用無線技術(shù)進(jìn)行組建室內(nèi)家電控制系統(tǒng)網(wǎng)絡(luò)，使各種家用設(shè)施(如照明、家電和室內(nèi)環(huán)境等)通過網(wǎng)絡(luò)進(jìn)行互聯(lián)，體現(xiàn)無線技術(shù)的方便和安全。
首先，本文在分析了國(guó)內(nèi)外智能家電系統(tǒng)技術(shù)現(xiàn)狀，針對(duì)智能家電系統(tǒng)存在的布線難、造價(jià)高、結(jié)構(gòu)復(fù)雜等問題，提出采用基于Zigbee無線通信技術(shù)的智能家電系統(tǒng)設(shè)計(jì)方案，進(jìn)行無線數(shù)據(jù)的采集和傳輸。
通過對(duì)智能家電網(wǎng)絡(luò)的分析、對(duì)比和研究，采用星型網(wǎng)絡(luò)組建智能家電系統(tǒng)的內(nèi)部網(wǎng)絡(luò)；利用TI的射頻芯片CC2420 Zigbee模塊和Microchip的微控制器PIC18LF4620設(shè)計(jì)并構(gòu)架成一種低成本，高靈活性、通用的Zigbee無線智能家電網(wǎng)絡(luò)。然后，介紹智能家電控制系統(tǒng)的軟件部分實(shí)現(xiàn)。利用Microchip提供的Zigbee協(xié)議，結(jié)合具體要實(shí)現(xiàn)的功能進(jìn)行編程。

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 system's internal network; the use of TI's 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.
Key words: Smart Home electrical appliances；Zigbee；PIC18LF2420；CC2420；
