So all kinds of parks in urban planning,which will build some fountain for people to relax, watch. Fancy fountain in the scorching sun of summer can reduce the temperature and increase the humidity effect。 can also make the waterflowing, for water self purification ability increase to prevent water black odor phenomenon. In some large and mediumsized cities, urban construction and Landscape Design Department of the fountain in the landscape to beautify the environment and cultural atmosphere of the proposed new requirements. Relevant professionals a lot of outstanding fountain, waterscape. A delightful,delightful, for people with a high degree of enjoyment in vision, hearing, get a good reflection of the social and social benefits. Many professional fountain equipment processing factory and pany began the rapid formation and development in this period, provide laid a good foundation for the future development of the fountain, the fountain has gradually bee an important means tobeautify the city, improve the environment. Fancy fountain is the core of PLC, is an electronic device designed for applications in industrial environments and design of digital puting operations. It can be programmed using the memory,used to perform the logic operation, sequence operation, timing, counting and arithmetic operationin its internal storage instructions, and through digital or analog input and output, machinery or production process control of various types. PLC and its associated peripheral equipment should be in accordance with the industrial control system is easy to form a whole, easy to extend its functions and design principles. This design is mainly to the programmable controller PLC control function, through the control of each switch, to meet the needs of the people of vision, to achieve the use of programmable controller to control the fountain patterns function, has the characteristics of simple wiring, easyprogramming, easy to expand etc.. When the fountains function increase or decrease the need for appropriate, as long as the increase or decrease the corresponding program and output function,want to change the place will be relatively less, the test results show that, in terms of practicability,sensitivity, accuracy and reliability, have reached the design requirements. Through this design, Ilearned a lot of useful things on the job in earnest and careful attitude has also been improved. And the programmable device to better understand the function.
