摘要
近年来,RFID技术的高速发展掀起了物联网的革命性应用,但RFID技术存在着读写器成本较高、推广难度大等缺陷,限制了物联网在国内的进一步发展。对RFID及其衍生技术NFC进行研究,提出一种基于NFC技术的物联网溯源系统,旨在提供一种廉价的、易于大规模推广的物联网解决方案。该系统以智能手机作为NFC读写设备和GPS定位设备,在不增加硬件成本的前提下解决了标签防伪、信息溯源、GPS定位等物联网关键技术。同时支持不依赖互联网的全流程离线操作,使其更加适合中国部分农村地区网络条件差的实情。该系统已在出口农产品物流领域进行推广应用,对于探索我国出口农产品物联网监管新模式具有重要意义,也在其他物联网应用领域有着广泛的应用前景。
In recent years,the rapid development of RFID technology has caused the revolutionary application of IoT,but the high cost of RFID devices limits the further development of IoT in China. In this paper,we studied RFID and NFC technologies and proposed a traceability system of IoT based on NFC technology. It aimed to provide an inexpensive and easy-to-promote IoT solution. This system solve the key technologies of IoT such as label security,information traceability,GPS positioning without increasing the hardware cost by using smart phones as NFC reading/writing devices and GPS positioning devices. The System supported an off-line operation without internet,making it more suitable for some poor-network-condition area of China. The system has been promoted and applied in the field of agricultural products exporting. It has great significance to explore the new mode of IoT regulation of agricultural products exporting in China. It has board application prospect in other fields of Internet of things.
