“数字果园”GPS数据采集系统的设计与实现

Design and implementation of GPS data acquisition system of digital citrus orchard

我国是世界柑橘生产第一大国,但单产、品质与美国、巴西等柑橘生产大国相比并不占优,急需提高柑橘园管理水平,"数字果园"是实现其精确管理的有效方式。介绍了分布式GPS数据采集系统的设计原则、系统结构和系统的主要模块,并采用ESRI公司的ArcEngine组件开发环境结合Microsoft公司的.Net平台进行了系统的设计与开发。系统运行结果表明,柑橘园面积采集准确率达97.2%,对县域柑橘产量估算精确率达84.7%。本系统的建成和投入使用对提高柑橘种植管理效率和水平具有重要意义,并为相关领域的GPS数据采集系统开发具有借鉴作用。

China is the first worldwide citrus production nation, but the per area yield and quality of citrus is less than thoes of such citrus production nations as USA and Brazil. It＇s urgent to improve the management level of citrus production, while ＂Digital Orchard＂ is an effective way to achieve exact management. In the paper, firstly, the design principle, system architecture, main module and critical technology for developing this system were introduced in detail. The COM based on developing environment-ArcEngine of ESRI and .Net software development platform of Microsoft were used. The sytems running results showed that accuracy rate of citrus orchard area reached 97.2%, citrus production estimates outcome of Yilin county, Hubei province reached 84.7%. The deployment of this system has a significant meaning on improving the management of citrus orchard administrative department, moreover. It can be used as reference for developing other GPS collection systems in agricultural fields.
