The Design Of Weed Chemical Control Computer Expert System

The system was built as a software according to the problem existed in the weed chemical control and the trend to the application of computer in the weed science. Our office staffs developed "weed chemical control computer expert system" software in order to solved the painful identification, herbicide misapplication and the problem that concerned the chemical control. This system, which made use of the ADO technique of Delphi to make the expert's knowledge into knowledge database was created by software Installshield with inquiry function and a certain intelligence. Without an expert, you can still identify weed, control weed at the same time. Visible programming technique together with friendly windows made the operation more vivid, convenient, fast. System supported fuzzy inquiry. Knowledge database can be continuously modified and enlarged along with the knowledge renewed continuously.This system included weed identification subsystem, herbicide information subsystem, weed control subsystem.The subsystem identified a weed according to the name, character of a weed, preparing for weed control. The database was arising from the collection of domestic and international book, it included the content of identification of the plant, seedling, anthotaxy, fruit and weed control. At the same time it contained the picture and introduction. The contents were thorough, and operation method was easy and fast.Herbicide information subsystem belonged to chemical control system, and gathered the related information of herbicide to integral one. It included the method of 11 kinds of interactive inquiry methods, and the customer can freely choose the inquiry method. The system showed the related information of matching the qualification and picture of chemical construction and the detailed information.According to the expert's knowledge, from the step of weed control, selecting farmland, selecting mode of the herbicide application and control subject, the weed control subsystem can give much advice to control weed.
