Design Of Large Scale Irrigation District Information System

With the rapid development of our economy, agricultural water total contradictions have become increasingly prominent, China's 402 large irrigation district, the total effective irrigation area of 240 million mu, accounting for the arable land area of 13%, is the main force of the agricultural production in china. The irrigation district informationization is an important means to improve the large scale irrigation district management and service level and quality, reduce the cost, is an important measure to realize the "total control" and "quota management" two sets of index system, is the inevitable direction of large-scale irrigation in the future construction and development.In light of the current situation of China large scale irrigation district information, using the knowledge of software engineering, discussed the large irrigation district information system requirement analysis, overall design and detailed design. Construction of large-scale irrigation from the information collection, transmission, processing to application software system, the large scale irrigation district information software system can greatly improve the accuracy of information acquisition and processing and transmission of the timeliness, feedback and forecast timely, accurate, and provide a scientific basis for the management of large irrigation area, enhance the efficiency and effectiveness of management irrigation district.The system design process, according to the information collection sensor devices in various forms and irrigation business diversity and individuality characteristic, uses the modular design, the system has strong scalability, function module can be configured to meet the irrigation area, different business needs.Construction and application of this system will establish a management system for large irrigation area leading, leading the development of irrigation area with modern science and technology, enhance the level of modern management of large irrigation area, the modernization of large-scale irrigation development along a healthy and scientific direction.
