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。In order to solve the issue that the information transfer of fresh produce supply chain is not continuous, incomplete and untrue, and to prevent agricultural health threat to people＇s lives, this study has developed a data collection terminal based on near-field communication technology. At present, China fresh produce market for primary agricultural products, food processing and consumer demand increases year by year, but the infrastructure and information technology applications of fresh produce supply chain are behind, resulting in high loss of fresh produce throughout the supply chain in the circulation process, as well as low efficiency and poor reliability of the information, and therefore it is difficult to meet the needs of the modern market of fresh produce. In recent years, the consumption of fresh agriculture products has been continuing to rise with the development of society and the growth in people’ s living standard. However, an increasing number of safety problems like poisoning and polluting have been triggered because of the quality problem of fresh agriculture products, which directly influences consumers＆#39; health and environmental security. Eventually, it has aroused widespread concern in the whole society. The discontinuity of fresh agriculture product supply chain information is one of the important reasons for the emergence of faulty products. The backwardness of data acquisition equipment and means in each link of fresh agriculture product supply chain, and the data in key link being not able to be collected due to environmental factors, are the main reasons for discontinuous information of fresh agriculture product supply chain. The paper first analyzes data collecting equipments of fresh agriculture product supply chain and its corresponding working conditions. Then, based on near field communication （NFC）, bei dou system （BDS） and global system for mobile communications （GSM）, it develops the integration technology data collection terminal of fresh agriculture produ
