With the national economic recovery and development, people's living standards, a number of urban cities, in the garden department in charge of urban construction, the process of transformation, as well as to beautify the environment and cultural atmosphere of the fountain of the demands put forward innovative widely used in the fountain of the process, there have been some problems and deficiencies, such as the low level of automation, high-energy consumption industries, such as restricting the development of the fountain. Therefore, improving the fountain level of automation control systems to ensure that the fountain effect, saving the cost of running the fountain, the fountain ofour industry isof great practical significance. PLC to control the use of fancy fountain, with easy to use, reliable operation and design of control procedures simple. Programming using ladder methods, design ideas can make a clear, simple programming. If need to change the water pattern and water time, the design of adjustment programs donot have tobe great, as long as the control procedures be amended accordingly, to achieve the control purpose. In this paper, details of fountain control systems engineering requirements, and in accordance wi
