农产品追溯的物联网应用模式

The Application of Internet of Things for Agricultural Products Traceability

物联网应用于农产品追溯是未来经济社会发展趋势,物联网的内容包括物体标准化标识、物物网络化连接、物体智能化管理;而在农产品追溯中,追溯目标是"借物管人",追溯内容是"人物信息",追溯要件是"目标兼容",追溯精度是"个批结合"。这表明物联网与农产品追溯具有内在的契合性。物联网应用于农产品追溯体系架构主要包括感知层、网络层和应用层,其中感知层是基础,将"物"纳入"网";网络层是保障,解决追溯链条"信息孤岛"问题;应用层是目标,是物联网价值所在。感知层具体应用模式主要包括信息采集内容、信息采集主体、信息采集方式、信息标识方式、信息存储方式;网络层主要包括传输内容、传输渠道、传输方式、传输安全;应用层主要包括应用层次、应用内容、应用方式。物联网技术应用于农产品追溯具体应用模式多种多样,必须因地制宜。

the application of Internet of Things for agricultural products traceability is the future trend of economic and social development, the internet of things can be summarized as： object standardized identification, physical network connection, object intelligent management; agricultural products traceability can be defined as： tracing target is ＂managing physical by people＂, traceability content is ＂people and physical information＂, traceability elements is ＂target compatible＂, traceability accuracy is ＂ combination single and a lot of＂. The Internet of Things and agricultural products traceability has internal fit. The system architecture of networks application in agricultural product traceability mainly includes perception layer, network layer and application layer, the perception layer is the foundation, which puts ＂material＂ into the ＂net＂： network layer is to protect and solve traceability chain ＂information isolated island＂ problem; the application layer is the goal, which is the traceability value. The specific application mode of perception layer includes information collection contents, collection subject, collection methods, identification methods, storage methods; network layer mainly includes transmission contents, transmission channels, transmission methods, transmission safe; application layer mainly includes application layers, application contents and application methods. The specific application methods of network application in agricultural traceability are various, which should be adapted to local conditions.
