| In the coming decades, there will be a growing worldwide shortage of water resources. In China, water, as a natural resource, is not only insufficient, but also unevenly distributed over the country. The agriculture accounts for 80% of water consumption. Automatic control in agricultural irrigation can raise the yield of crops and cut down the cost of production as well as solving the problem of water shortage. In the view of particularity of agricultural irrigation and the situation of my country, there will be a expensive foreground of application of wireless control irrigation system. In this paper the composition, the characteristics and the functions of every part in this system are introduced; the hardware's structure is explained in detail; the control flows of software are researched. In the end, the existing problems of the system and the ideas of software and hardware in further contents and approaches are proposed. |
