摘要
移动互联网快速发展和智能手机在农村普及为进一步完善精准施肥系统提供了有利条件。以当前主流的Android手机操作系统为平台,运用GPS定位、Baidu Map API和数据库等相关技术,设计并实现了基于手机LBS和移动GIS的玉米精准施肥系统。该系统通过无线网络进行用户端与服务器端的信息交互,服务器端运用土壤肥力丰缺指标法、玉米喜肥特性法以及养分平衡算法对数据进行分析和处理,生成施肥方案并推送给用户。结合测试表明,该系统通过GPS定位,定点定位误差<4 m,各模块响应速度在5~15 s。
The rapid development of mobile Internet and smart phones in rural areas provides favorable conditions for further improvement of precision fertilization system. Android, the mainstream smart-phone operating system, is used as the platform, coupled with such related technologies as GPS, Baidu Map API and database, precision fertilization system of corn is designed and realized based on mobile LBS and mobile GIS. With the help of wireless network, the system makes it possible to exchange information between user and server. The server analyzes and processes the data by applying soil fertility abundance index, fertilizer tolerant characteristics method and nutrient balance algorithm, and then comes up with the fertilization scheme and submits it to customer. Test results indicate that the system keeps the error of location within 4 m and the response speed of each module is within 5 to 15 seconds.
