Based On Nc Agriculture Intelligent System Integration Framework Of Realization

With the development of the intelligent information technology, the intelligent system (Expert System) is more and more maturated and perfect. It made big progress in Knowledge Acquisition, Knowledge Representation, Problem solving, reasoning technology, information security, use cost. As the same time the agriculture intelligent system development tool got effective improvement and breakthrough progress in every aspects too.Combining domestic independent Intellectual property right computer technology with advanced agriculture production technology on the base of the NC (Network Computer) is significant in solving the problem such as the lack of agriculture expert and technician, reducing the cost of development, accelerating the agricultural production level. The intelligent agriculture application software is the concrete application in agricultural production of modern information technology, it's the effective way to combine the new and high technology with traditional agriculture and it's also the important contents of revolution in agriculture science and technologies.The theses adopts Internet and distributed calculating technology and put forward a software integrated mechanism based on NC/Linux, developed series of components such as network service, data service, numerical value calculating, interface of man and machine and so on, made research in the partition of function components, project deployment and built a multiplayer, open, flexible and component integrated framework of agriculture intelligent system on the base of this, the integrated framework supports custom-built, assembly and cooperation development of agriculture intelligent system, which makes the agriculture expert system developed by it has high expansibility, reliability, mutual-operation and reusability and easily to use for different clients.The integrated framework has such three parts as development platform, system kernel and running environment. Development platform includes component interface supported IDL compiler, system debugging and measuring tools, description of distributed component and packing tools. System kernel includes the basic realization of distributed function component of Knowledge Acquisition, Knowledge Representation, reasoning control, explain tactic. Running environment can be divided into basic running environments and high available running environment, basic running environments is used for and support individual distributed intelligencesystem; High available running environment is used to support the high performances of server calculating and management and visual application in client end. The integrated framework supports from distributed component IDL definition to the whole distributed application development flow of setup, running, control of component application and the distributed components developed accord with component standard, can easily integrate with other software products which follow J2EE standard.The research and realization of integrated framework of agriculture intelligent system based on domestic NC/Linux is propitious for second developer to develop high quality and applied agriculture intelligent system and reduce the difficulty of building the distributed application and makes agriculture technicians to solve the agriculture questions with their all energy and experience. In addition, the research can accelerate the spread of our national computer software and hardware technology in agriculture field and it's significant to heighten the level of national agricultural informationization.
