The Design And Implementation Of Wheat Planting Decisions Support System Based On B/S Architecture

In the modern agriculture, the extent of informationization has become an important sign of measuring the agriculture level of a country. In recent years, countries have established their own crop decision support system based on their own crop growth simulation model. Such systems are essentially based on the C/S architecture, because the C/S architecture can effectively solve the usage problems caused by poor performance of early computers or the immature of server technologies depend on its distributed architecture. And the single platform support can reduce the development cycle of system. However, as network and server technology matures, the distributed architecture of C/S is not conducive to the maintenance of the system. Furthermore, C/S architecture model does not allow the software based on different platforms run cross-platform, and it need amount of work to optimizing. These disadvantages make the C/S architecture technology significantly worse than B/S architecture technology. To solve these problems, a wheat planting system has been designed based on B/S architecture, and introduced in this dissertation. The main contents are as follows:(1) At home and abroad, the research status of crop decision support system has been introduced, and the deficiencies of the current system of planting decisions have been analyzed. Then the design of wheat planting decision support system is proposed based on B/S architecture technology. From the perspective of the technology, the aid decision support system is used as a blueprint to design the system. The technical support is provided by the computer software technology in the NET framework sets and ASP technology,the ADO and SQL Server technology of database technology, B/S architecture technology in software architecture. The software requirements analysis is performed in three aspects: functional system requirements, user requirements and performance requirements. System architecture diagram components of the system and the system function of each module have been obtained by analyzing the user case diagram.(2) The presentation layer, business logic layer and data layer of wheat planting design system are proposed based on the system architecture, and then it is designed and implemented. First, the growth anddevelopment model water dynamic equilibrium model and production management and technical knowledge model in wheat planting process are analyzed, a mathematical model is established and the relevant algorithms are compiled. Then, based on the Visual Studio 2010 development environment, C #development language is used to design and implement the interface design, database design, planting technology modules, fertilization program module, weed prevention module, species selection module,disease control module, water management module and other aspects, and the selected functional modules as core code sowing technology modules are described in detail.(3) Finally, the wheat planting design system has been tested, and the black box testing draw ideas are used for reference. Some testing has been taken to proof the functionality and performance of the system,such as feature implementation testing, system load capacity testing, system testing, fault tolerance, and the test results are confirmed the efficiency and reliability of the proposed systems.
