3S技术的农产品溯源模拟系统的设计与实现

Design of Agricultural Products Traceability System Based on 3s Technologies

现有农产品溯源系统存在平台不统一、系统不兼容、缺少农产品生长时的估产、病虫害的监控数据而使统数据不能共享等缺点。针对这些问题研究将整个溯源系统划分成浏览器、服务器、数据库三部分,利用Adobe Dreamweaver CS5软件、CSS标签以及HTML语言进行浏览器的开发,tomcat软件以及servlet、jsp技术制作服务器,以及SQL语言支持数据库的管理。同时在系统中融入了3S技术,利用RS影像监测农产品生长中的病虫害并估产,以GPS技术来跟踪农产品运输的过程,利用GIS技术来进行农产品适宜性评价以及对整个系统中产生的数据进行按地区分类的空间数据处理,并将所有处理后的数据以最直接的形式呈现在系统中。

At present, lack of national unified traceability system and incompatibility of various regional traceability systems make date on agricultural products traceability systems unsharable around the country .Moreover, the existing traceability systems are not quali-fied with functions of estimating production and recording the products＆#39;history of plant diseases and insect pests.To slove the problem, the study establishes a new traceability system by improving its function from three aspects：the browser, the server, and the database.Adobe Dreamweaver CS5, CSS and Html language are used to perfect the function of the browser .The server is designed by tomcat software and technologies like servelt and jsp.SQL language help to optimize database operation.Additionally, 3S technologies are used in the system. Plant diseased and insect pests, which products suffered with, can be recorded by RS Image.The production of agricultural products also can be estimate according to RS Image .GPS will trace the transport rout of products .GIS not only makes a evaluation on the product suit-ability, but also classifies data by region and present them by the system in an understandable way .
