基于北斗卫星导航系统的地理标志农产品地采集保真系统应用研究

Research on Application of Geographical Indication Agricultural Product Land Collection Fidelity System Based on Beidou Satellite Navigation System

北斗卫星导航系统是我国为全球用户提供全天候、全天时、高精度的定位、导航和授时服务的国家重要时空基础设施。当前一些地理标志农产品保真方案存在无法保证农产品原料来源问题,本文充分利用北斗卫星导航系统的高精度定位、时间信息,研制了基于北斗卫星导航系统的地理标志农产品地采集保真系统。该系统包含原产地地块监测集成设备、溯源认证二维码、电子围栏、时空区块链等模块,并在云南省部分地区农产品上进行了示范应用,结果发现,该系统对消除次品、提高品牌价值、促进农产品销售等具有很好的效果。

The Beidou satellite navigation system is an important national spatiotemporal infrastructure in China that provides global users with all-weather,all-day,high-precision positioning,navigation,and timing services.At present,some geographical indication agricultural product fidelity schemes cannot guarantee the source of agricultural raw materials.This paper fully utilized the high-precision positioning and time information of the Beidou satellite navigation system to develop a geographical indication agricultural product land collection fidelity system based on the Beidou satellite navigation system.The system included modules such as origin land monitoring integration equipment,traceability authentication QR code,electronic fence,spatiotemporal blockchain,etc.It had been demonstrated and applied on agricultural products in some areas of Yunnan Province.The results showed that the system had good effects on eliminating substandard products,improving brand value,and promoting agricultural product sales.
