摘要
针对信息化家电的发展趋势,结合嵌入式技术、短距离无线通信技术,设计了应用于信息家电无线控制的节点。节点设计采用CC2500系列2.4GHz射频芯片为无线通信模块,扩展了PCF8563为实时时钟,并以低成本的STC单片机为控制模块。并且在理论分析的基础上给出了软硬件设计要点。该节点体积小、功耗低、成本低,具有很好的应用前景。
With the trend of information appliance,this paper discussed the design of the wireless node which combines with the embed technology and the short range wireless communication technology used to control the information appliance.2.4GHz RF chip CC2500 and STC series microchip were adopted in this node as wireless communication module and CPU respectively.PCF8563 was used as an real-time clock.And some key design points based on the theory analysis were showed.With the advantages of small size,low power and low cost,the node has an bright practical prospect.
