【摘要】 用Visual FoxPro数据库管理系统管理数据,用ADO控件连接数据库,用Visual Basic编写程序代码,完成了神经网络测报模型,作为病虫害测报系统软件的一个功能模块,该模块包括六个功能子模块:数据导入子模块用于将数据从磁盘文件中导入系统;参数设置子模块用于对各种初始参数进行设置;数据标准化处理子模块用于对原始数据进行标准化处理;激活函数的选择子模块用于选择不同的激活函数;学习训练子模块用于对模型进行学习训练;测报子模块用于预测预报病虫害的发生情况。为病虫害的预测预报提供了一个操作简单、方便实用的工具软件平台。测报工作者可以根据自己实际的原始数据组建成当地实用的神经网络模型,并测报应用。更多还原

【Abstract】 The neural network forecasting model,as a function module of the pest and disease forecasting system software,was designed and implemented by Visual Basic,using Visual FoxPro database management system to manage data,with the ADO control objects to connect to the database.There were six functional sub-modules in the module,such as: Data inputting sub-module was used to input data from a disk file;Parameter setting sub-module was used to set various initial parameters;Data Standardization processing sub-module was used to standardize the Original data;Active function Selecting sub-module was used to select a different active function;Learn training sub-module was used to train learn for real model;Forecasting sub-module was used to predict and forecast the occurrence of pests and diseases.Prediction of workers may use this platform to set up the real neural network forecasting model and release the real occurrence of pests and diseases.It provided a simple,convenient and practical tools software for pests and diseases forecasting.更多还原
