摘　　要：借助于抗扰物联网技术,科技产业能够实现精细化管理、高效化运作。借助现代科技,基于NFC实现抗扰物联网监测系统的研究与设计。虽然我国当前已经逐步构建抗扰物联网通信系统,但其存在着布线难、操作难、数据传输难等阻碍问题,而据分析近距离通信技术构成的两级农业监测信息物联通信方案能够有效解决当前阻碍。因而通过设计Zigbee自组织网络改善系统内的各个模块的数据无线传输;在系统中纳入NFC技术,达到整个系统整体同移动终端的近距离无线传输,针对数据传输在检测中出现的干扰性较强的问题,提出运用捕获算法(PMF-FFT)。该算法融合了部分匹配滤波器和FFT技术,能够实现通信干扰对消除并比传统系统更加节约能源消耗。最终对基于NFC的抗扰物联网监测系统通过实践操作进行了验证。By means of agricultural IOT,agricultural production can achieve fine management andefficient operation.However,there are some problems such as difficulty in routing and operation of IOTin agriculture.In this paper,the communication scheme of the agricultural monitoring is proposed,which is composed of ZigBee self organizing network and close range wireless communicationtechnology(NFC).In this scheme,the design of ZigBee self organization network is realized from thedata acquisition node to the host module.The NFC technology is used to realize the wirelesstransmission of the whole system and the NFC mobile terminal.Aiming at the problem of highinterference in the process of agricultural monitoring data in wireless communication,a PMF-FFTalgorithm based on partial matched filter(FFT)is proposed.Through a set of experiments,theproposed communication scheme is verified.
