Abstract: A componentware flow chart of the platform for agricultural intelligent system is analyzed in detail and a component oriented and adaptive software integrated model is put forward in this paper. The assembling and assembling guide of the system function components can be carried out according to the model. A basic framework of common component is built which can be extended and cut down freely, and the framework adopts respective method to describe interfaces, restrictions and mutual protocols of the reusable components, and provides the extending mechanism in XML. An agricultural intelligent system platform for componentwares is developed on the basis of the study of the framework. The platform provides agricultural information technician a uniform, convenient development entironment and tool. It is significant to improve the quality and shorten the development cycle for agricultural intelligent system.
