Disaster Reduction And Pollution-free Vegetable Planting Expert System Based On Web

At present, the function of web-based protected horticulture vegetable planting is single and the kinds of vegetable are few, in view of the shortage, the Disaster Reduction and Pollution-free Vegetable Planting Expert System Based on Web is presented and the design and realization of the system is introduced in the paper.In the full analysis of the user's demand, bathed on the experience summarized by the expert, the knowledge library, the inference machine, the database and its management system has been designed. The object-oriented knowledge expression, the pro and con inference strategy and the breadth first searching strategy are introduced. The pruning bathed on the typical character reduced the search time and enhanced the inference efficiency. The disease diagnosis, the management and the study function of the protected horticulture vegetable planting has been realized successfully, the collection usability.Based on Windows 2000 server operating system, take C# as the development platform and Microsoft Visual Studio.net as the development kit, the system is built by using object-oriented technology. The system consists of diagnoses subsystem, the inquiring subsystem, the forecast subsystem, the management pattern optimization, the weather disaster reduction, the knowledge maintenance, etc. Kinds of protected horticulture vegetable planting knowledge, the technology of the prevention and cure of diseases and the technology of agricultural establishment is integrated in the system.The technologies of expert system and the network and ASP.NET are introduced briefly, the constructing process and the main point of the technique are analyzed stressfully. The constructing method of the system is proposed in the paper, the technologies of ASP.NET and ADO.NET are introduced to access the dynamic database, the expert system network has been realized, the expert system application space has been expanded, the sharing of vegetable planting knowledge has been built up, and the foundation for further researching has been built in this paper.The system is developed for agricultural technicians and farmers, it provides service platform for non- environmental damage production, the recognition and controlling and scientific management, and so, there is more practical value and the development prospect for it.
