近年来,国内外农产品安全事故频发,建立农产品安全追溯系统是保障农产品安全的重要技术措施之一,受到了越来越多的关注,并在农产品的生产和流通中加以应用和推广。本文首先总结介绍了农产品安全追溯系统的含义和意义,然后介绍了发达国家以及中国农产品安全追溯的现状包括法律法规相关标准的制定以及追溯系统的具体实施等,由此分析出我国农产品安全追溯系统存在法律法规和标准体系不健全,技术不够成熟成本高等问题,并结合我国国情提出了合理的改进方向如政府通过给予补贴推广该系统等,最后预测了农产品安全追溯系统的发展趋势之一是通过数据分析实现指导农业生产和资源分配等。 相似文献

可追溯体系与食品安全——基于委托代理模型的分析 总被引:2,自引:0,他引:2
在食品供应链中建立可追溯体系,能够显著地影响与食品安全相关的道德风险问题。可追溯体系的精确程度决定着食品安全的责任划分,从而决定着食品供应者应承担多大比例的食品安全成本。该文通过建立一个食品安全委托代理模型,分析了降低食品供应链中道德风险所必需的最低追溯精确度水平,并据此讨论了食品安全监管的相关政策建议。 相似文献

A method for combining data stored in an RFID microchip implanted inside grapevine plants and a GPS system is described. GIS software was used to register geographic coordinates of detected points, and to develop a specific database in which information useful for the positioning phase are stored. The final product is a digital map accessible via mobile or desktop systems that represents the “virtual vineyard”. In this digital representation, each grapevine plant marked by RFID can be selected, viewed and edited. Free-to-use software was implemented for use by consumers. 相似文献

Documentation is a major component of any traceability system where traceability is defined in the ISO Regulation 8402:1994 as the ability to trace the history, application and location of what is under consideration. Traceability systems are record keeping systems designed to track the flow of product or product attributes through the production process or supply chain. All international supply chains are forced to comply with traceability requirements. In this paper, we develop and implement an end-to-end mobile application prototype that traces the poultry production. This application consists of front-end and back-end systems. At the front-end, the worker uses a GPRS enabled handheld device (cell phone, PDA, etc.) to capture information on poultry operations collected at a remote chicken farm and transmit it to a back-end server in the main office. Through customized application the back-end server analyses all information received from the front-end and based on a built-in business process and business rules, intelligently updates various stakeholders of any breach of bio-security measures that requires immediate attention. The proposed system administrators can also access this application via Internet for management decision making. The back-end system consists of web server, defined business application logic and database server. 相似文献

[目的]针对生猪养殖阶段特点,设计基于RFID技术的畜产品可追溯系统。[方法]阐述电子标签和读写器的天线设计方法,并采用不同的天线对可追溯系统进行通信测试。[结果]数据传输率等参数设置相同时,外接天线的通讯距离比PCB天线要远;3种外接天线比较而言,同轴天线和壁挂天线的通讯距离较远;500kbps数据传输卒时通讯距离在28m范围内,250kbps数据传输率时通讯距离在40m范围内。从硬件成本角度考虑,壁挂天线价格远高于同轴天线,在相同通讯距离要求时,系统选用同轴天线。[结论]在生猪养殖阶段采用该研究设计的有源电子标签和读写器,可提高猪肉产品的安全性,并对彻底实现食品的“源头”追踪和提供食品安全的透明化管理提供技术支撑。 相似文献
