构建物联网采用的两大技术——无线射频识别技术(RFID)与无线传感网络(WSN)技术的融合是当前科学研究的一大热点.我国在这一领域上已取得了很多成果,虽然研发了许多物联网产品,但是目前RFID和WSN融合技术相关的详细资料非常少,其中大部分资料里硬件设计多采用功耗大的单片机,系统体积较大,使得样机的节能环保能力和便携性能都有缺陷.从实用性考虑,给出了低功耗小尺寸C8051F410单片机、便携式系统设计方法,重点讨论了RFID与WSN融合技术中,利用RFID模块MFRC522设计的技术细节,实现了XBee模块与单片机的硬件接口.还提出了基础功能函数和底层功能函数的概念,并结合系统调试需求,给出了一种使用串口调试RFID模块的详细方法.%Radio frequency identification (RFID) and wireless sensor network (WSN) fusion technology both of which construct the internet of things is one of the most popular scientific purposes. China has made great efforts on the subject. Although many progress has it made. There are very little detailed material at present about RFID and WSN. Most of the material uses high-power-consumption hardware designed of single-chip microcomputer,large size,makes the prototype system of energy conservation and environmental protection ability and portable performance are flawed. From practical point of view,this paper,based on the low-power-consumption C8051F410 single-chip microcomputer,small embedded system design method,and discusses the RFID and WSN fusion technology,the use of RFID technology MFRC522 design details,and provide a XBee software interface module and the realization of the design,realize the XBee and MCU hardware interface. On the basis of the completion of hardware and software interface,this paper puts forward the basic function and the underlying function and puts forward a RFID debug method of using a kind of serial port software and hardware.
