Design And Implementation Of Management System Of Wheat Crop Information Based On DOA

With the rapid development of agricultural science and technology,the widespread application of agricultural information management technology makes the production of agriculture develop rapidly.But because of the agricultural information description,the standard of definition,acquisition,representation and information application environment has not yet been unified,which results in a large number of data information dispersed and independent,it is difficult to use in wide area and integrated environment,and a large number of different structure types of agricultural information management systems are complex and have low scalability.The result is that the agricultural data storage is scattered,the data sharing is comparatively low,the structure complexity is large,and the multi-source heterogeneity of agricultural data leads to the contradiction between the agricultural data is difficult to integrate management,and the information resource which is wasted by a large amount of data information resource is seriously deficient.In view of the diversity and heterogeneity of wheat crop information in large quantities,at the same time,in the face of the information management of wheat crop,the management system is jumbled and diverse,the agricultural data storage is scattered,one-sided,the lack of efficient and reasonable integrated management of wheat crop data and so on,put forward the wheat crop data as the research object,The design of wheat crop management system based on DOA architecture,combining the characteristics of wheat crop data and the characteristics of DOA architecture,the design and implementation of wheat crop management system based on DOA architecture is carried out.The wheat crop management system based on DOA architecture can unify,the management of wheat crop data efficiently and rationally,and the dynamic scalability and data sharing of wheat crop management system,the integration and management of wheat crop information diversity and heterogeneity,and the improvement of information service quality in wheat production,To some extent,the environmental quality monitoring,production process monitoring and product quality monitoring of precision agriculture are further strengthened,which has high application value to wheat production.At the same time,the design of wheat crop management system based on DOA realizes the application of DOA architecture in agricultural crop management system.The main contents of this paper are as follows:(1)The architecture of wheat crop management system based on DOA architecture is designed.According to the characteristic of DOA architecture,the design of data registry DRC metadata;According to the characteristics of farming,diversity and heterogeneity of wheat crop data,the scheme of data storage is designed,and the application function of the system is designed according to the process of wheat crop information collection,processing,analysis,management and display.(2)Methods for the storage of wheat crop data.The classification and characteristics of wheat crop data are analyzed,and the data storage design of different storage types is carried out according to the application requirements and performance of agricultural management system under the DOA architecture.(3)The application function of wheat crop management system based on DOA was designed.In view of the function demand of wheat crop information collection,processing,analysis,management and visualization,the system function design is made from the basic application function of wheat crop data management and the application function based on GIS.(4)Complete the implementation of the system.On the basis of(1)and(2)and(3),combined with practical application requirements,the system functions are integrated and developed,and the application functions of the system are realized from three systems of agricultural information collection and visualization subsystem,agricultural information data processing subsystem and agricultural information query and visualization subsystem.
