| In developed countries, automatic management of irrigation water is an important way to progress efficient production agriculture. To fit the new model of irrigation agriculture, it has actual and far-reaching meaning to realize a water delivery and distribution system of automatic collection, net transmission, digital memory and scientific decision for irrigation areas and then to improve their automatic management level.First, under systematical analyzing the present condition and requirement of irrigation areas and the relative technologies' present condition and development direction of inside and outside countries, this paper apply new technologies, such as modern communication technology, automation measure technology, control technology, CIS and visual technology etc, to automatic water delivery and distribution in irrigation areas. Then, with a key researching on automatic record of stage-discharge, remote supervising of gates, supervising of pump houses with a computer and communication net' s building between irrigation areas, we constructed a visual decision-making system of dispatching management for water delivery and distribution in thrift irrigation areas through the combination of different vocations and subjects. With this system, the control center of water distribution can remote supervise the condition of water delivery and distribution and real-time control the gates and the pump houses, then a dispatching management system is formed with irrigation nets. Under the overall dispatch and management, the irrigation areas will preliminary realize automatic water supply on the condition of requirement quantity. At last, obeying the role of uniting theory with practice, we select Shimen irrigation area of Shaanxi province as a demonstration object. Then, according lots of investigations and previous study results, the paper give a best project of automatic water supply system and also develop a set of corresponding application soft for the research irrigation area. |
