【摘要】 越来越多食品安全问题的出现,使食品安全问题在当今社会成为一个受到广泛关注的问题。与此同时,物流信息科技的发展以及二维条码技术的成熟,使得二维条码技术在食品追溯中发挥着越来越重要的作用。二维条码具有的信息容量大、可靠性高、安全性好,可以存储数字、字符等文本信息以及存储图像信息等特性,都使二维条码在当今社会条件下得到了快速的发展及应用。本课题基于食品安全问题,提出了利用二维条码中QRcode条码,建立以QRcode为载体的食品安追溯系统,这对于解决长久以来的食品安全问题具有重要的指导意义。本文根据QRcode的特点,研究了二维条码中QRcode条码的编解码技术以及图像处理技术；分析了食品安全追溯的研究现状,通过实现对各种追溯编码技术以及数据库技术的综合比较、选定,明确了食品追溯系统建设以及要达到的功能目标；提出了建立食品安全追溯系统的具体实施方案和方法。最后,以果品为例建立了基于QRcode果品安全的追溯系统,并阐述了基于QRcode食品追溯系统的数据库建设以及模块设计。通过对果品种植阶段,生产加工阶段,质量检疫阶段和销售流通阶段的实时信息录入,确保了果品安全追溯可靠性,从而实现果品追溯管理的全程跟踪与管理,保证了果品质量的安全追溯。更多还原

【Abstract】 Currently, food safety is becoming more and more concerned about as the the emergence of food safety issues. Meanwhile, two-dimensional bar code technology plays a more and more important role in the food traceability with the development of logistics information technology and the maturity of two-dimensional bar code technology.Two-dimensional bar code has been under rapid development and application in today’s society because of its large capacity, high reliability, safety, and its store characters of number, text and image information. Based on food safety problems, a food safety traceability system using two-dimensional bar code features and QRcode as a carrier is put forward, which is great useful for resolving the food safety problems.According to the characteristics of QRcode, the QRcode coding, image processing, decoding is introduced. The research status of food safety traceability is described. The construction of food traceability system and the functional objectives are defined by the comparison of kinds of traceability code and database technology. The specific models and methods of food safety traceability system are set up in the paper,Finally, a safety food traceability system based on a fruit example is described and the model design used QRcode is introduced. The reliability of fruit safety traceability is ensured by the instant data entry from the stage of plant, product and process, quality quarantine, etc. Thus, it can realize the whole process traceability, management and safe quality of fruit food.更多还原
