人参食品追溯链地理信息可视化方法研究

Studies on the Geographic Information Visualization Method of Ginseng Food Traceability Chain

针对人参食品可追溯链在物流运输环节中动态地理定位信息可视化问题,在深入研究Android地理定位和Google Maps API技术的基础上,利用智能手机可移动通讯特点,以HTC Sensation手机为测试平台,提出了将人参食品追溯链地理位置及路径信息进行可视化显示的方法。软件测试结果表明,该方法通过用户手机提取包装条码信息的同时,可以动态显示食品的地理位置和历史路径可视化信息,有效辅助可追溯链的信息查询和管理。

In order to resolve the visualization problem of dynamic geographic location information in logistics transportantion of the ginseng traceability,the method based on studying Android geographic lacation and Goolge Maps API was proposed.The method with advantage of intelligent mobile phone communication features dynamically displayed information of the geographic location and path of ginseng food traceability chain on mobile phone-HTC Sensation.The software testing results showed that while extracting packing barcode imformation by using the intelligent mobile phone,it could dynamically display visual information of food geographical position and historical path on the phone to assist the information query and management of traceability chain effectively.
