【摘要】：为了解决生鲜农产品供应链信息传递不连续、不完整、不真实等问题,防止农产品给人民生活健康带来威胁,该研究开发了基于近场通信技术的数据采集终端。该文分析了生鲜农产品供应链数据采集设备及工作环境的特点,开发一种基于近场通信技术(near field communication)、北斗系统(bei dou system)及全球移动通信系统(global system for mobile communications)集成技术的生鲜农产品供应链数据采集终端。该终端包含4个模块:NFC模块、系统CPU模块、北斗模块和GSM模块及电路系统。终端在写入数据时,同时将北斗加密数据通过NFC芯片PN532写入NFC标签,并通过GSM模块以短信的方式传递给后台数据库,利用RS232将数据信息传入节点企业平台,实现生鲜农产品数据信息的三重备份。该采集终端借助物联网及无线传感网的技术优势,实现生鲜农产品供应链各环节数据的自动智能采集并进行加密,满足企业在生产过程中不断变化环境下的数据采集及存储需求,该终端在极端环境下读取速度虽然降低了10%~25%,但存储率依然为100%,满足生鲜农产品供应链数据采集的需要,能够实现节点企业间信息连续度,为实现生鲜农产品可追溯提供参考。
[Abstract]:In order to solve the problems of discontinuity, incompleteness and unreality of supply chain information of fresh agricultural products, and to prevent agricultural products from threatening people's life and health, a data acquisition terminal based on near field communication technology was developed. This paper analyzes the characteristics of supply chain data acquisition equipment and working environment for fresh agricultural products. A data acquisition terminal for fresh agricultural products supply chain based on near-field communication technology (near field communication), Beidou system (bei dou system) and global mobile communication system (global system for mobile communications) integration technology is developed. The terminal consists of four modules: NFC module, system CPU module, Beidou module, GSM module and circuit system. When the terminal writes the data, the Beidou encryption data is written into the NFC tag through the NFC chip PN532, and transmitted to the background database by the GSM module in the form of short message, and the data information is passed to the node enterprise platform by RS232. Realize the triple backup of fresh agricultural product data information. With the help of the technology advantage of Internet of things and wireless sensor network, the collection terminal realizes the automatic intelligent data collection and encryption of the fresh agricultural product supply chain. To meet the requirements of data acquisition and storage in the changing environment during the production process, the terminal can read in extreme environments, although the speed of reading is reduced by 10% and 25%, but the storage rate is still 100, which meets the demand of fresh agricultural products supply chain data collection. It can realize the continuity of information between nodes and provide reference for the traceability of fresh agricultural products.
