基于物联网的农产品质量安全溯源系统

摘要

By using QR two-dimension code, traceability and information technology, agricultural products traceability system for quality and safety based on internet of things (IOT) was developed. The system is characterized by multilevel, multi-role and multifunction. The system includes web management, SMS management, smartphone management, barcode printing system, supermarket system, and website. Environmental information is automatically collected to the central database by IOT equipment, and the photos of production process are uploaded with mobile phone via 3G net. The traceability code has 20 numbers, including type, administrative division, company, product, date and batch number. Consumers could get the safety information of products purchased by the QR code, which is made of the system with 20 traceability codes. In other word, the system could be a kind of service platform for agricultural products safety evaluated by consumers.%采用QR二维码、溯源、物联网等技术,结合农产品产业链的特点,开发了多层次、多角色、多功能的农产品质量安全溯源系统.该系统包括网络管理、短信管理、智能手机管理、条码打印、查询机软件和查询网站.通过物联网自动采集环境信息和手机拍照快速上传生产过程图片,作为农产品的源头信息.使用20位的农产品追溯码(由类别、行政区划、公司、产品、日期和批次组成),并对此码进行网址转换,自动生成通用的QR溯源码,形成一个具有三方满意和消费者评级功能的便民服务平台.
