中文摘要：

病虫害的预测、预警,是保障粮食作物生产安全的关键技术,为克服传统的人工观测预报方式存在信息不准确、数据延迟等问题,设计基于物联网技术的寒地玉米大斑病预警系统。系统在ASP.NET平台下,通过WCF服务读取监测数据,采用Silverlight技术设计用户交互界面,调用ArcGIS的GP服务获取预警结果。应用实践表明,农田传感器监测网络获取的作物生长环境数据实时、准确,大斑病预测预警模型针对性强、实用可靠,预警结果简单直观,能够在一定程度上对寒地玉米生产起到辅助决策作用。

英文摘要：

Prediction and early-warning of disease and pests is the key technology to ensure the production safety of food crops.In order to overcome the problems such as information inaccuracy and data delay in the traditional artificial observation and forecast of the disease and pests,the early warning system of northern corn leaf blight based on internet of things technology was designed and implemented.The system is designed on the ASP.NET platform,getting the monitoring data through WCF service,using Silverlight to design the user interface and the GP service of ArcGIS to obtain the early warning results.Practical application shows that the environmental data acquired by field sensor network is real time and accurate,the early-warning models of northern corn leaf blight are targeted,practical and reliable,and the results are simple and intuitive.This system can play a supporting role in maize production to some extent.
