摘要: 针对当前食品安全事件频发的情况,设计和实现了基于COM技术的PDF417二维条码编解码组件,并将其应用到食品安全回溯系统中,通过对食品生命周期的有效监控,对问题食品进行回溯,迅速实现问题食品源头和流向的快速定位.Abstract: Because the current situation of the frequent occurrence of food security events,PDF417 two-dimensional bar code encoding and decoding components were designed and implemented based on COM technology,and applied to the food safety backtracking system.Through effective monitoring of the life cycle of problems food,they can be traced quickly,and the source can be found and the fast positioning of the flow of food can be achieved.
