基于视频监测和可视化模拟的大麦生产管理专家系统设计与开发

为给大麦生产提供栽培咨询、农情监测、生长状况比对、田间管理决策等技术服务,设计开发了一套大麦专家系统。本系统结合甘肃大麦生产实际和专家种植栽培技术及经验,采用Visual Basic研发了主界面,由VC++调用OpenGL图像库开发的大麦生长模型的模拟结果,嵌入了LabVIEW设计的大麦田间监视窗口界面,并利用Access软件开发了其数据库。试验结果表明,该系统界面友好,生产咨询栏目浏览便利,远程视频监控大麦田间状况失帧率范围为1.02%~1.11%,可实时模拟大麦可视化生长,并能与田间实际比较分析,误差值为0.15~0.25,能实现大麦田间管理和病虫害防治等推理决策,可信度高,可为抢抓农时的生产管理提供一种农业信息化技术新途径。

Designing and Development of Barley Production Management Expert System Based on Monitoring and Visualization Simulation

The barley expert system was developed based on the expertise of experienced professionals and the data of barley collected from six ecological zones in Gansu province of China. It mainly provided query, monitoring, simulating visualization, reasoning and decision-making services about barley cultivation. In this system, Visual Basic software was taken as a developmental tool, and OpenGL graphics library in the VC++ and LabVIEW software were used to complete the simulation of growth process and monitoring, and Access software was used to develop database. The experimental debugging results showed that the system was easy to use.For example,it could provide a reasonable decision alternative,and meet the surveillance requirements for a broader area,and compare the actual with simulated growth process of actual with simulated, which provides a new way for users to manage farming field.
