基于GPS的农产品原产地定位与标识系统

摘要

With the aim to ensure the integrity and objectivity of agricultural products traceability chain and provide agricultural information to consumers, a GPS-based origin positioning and identification system was designed for agricultural products, especially for the regional agricultural products and products labelled with protected destination of origin. The GPS model was integrated with electronic scales with the information of agricultural products. The practical application shows that the system can effectively verify the labeled information with GPS information to realize the origin positioning and identification for agricultural products.%针对区域特色农产品和受到“指定原产地保护”的农产品,设计了应用GPS的农产品产地定位与标识系统.通过将GPS模块集成到多功能溯源电子秤中,实现对农产品产地信息的获取、存储、加密以及标识打印.通过该系统,可以将产地名称与客观地理位置信息相关联,验证产品标识与实际信息的相符程度,将其反映至农产品标签中,并最终提供给用户,供其查询与验证.系统的实际测试结果表明,其产地判断准确率可以达到97％.
