摘 要 随着我国经济文化不断的加速发展，物质生活水平的提高促使着人们迫切的追求更高的生活享受，花样喷泉可以在人们周围随处可见，比如广场、、、花样喷泉的核心是PLC，是一种以微处理器为核心、带有指令存储器和输入输出接口、综合了微电子技术、计算机技术、自动控制技术、通信技术的新一代工业控制装置。它能够存储和执行指令，进行位置控制、逻辑控制、顺序控制、定时、计数和算术运算等操作，通过数字式和模拟式的输入和输出，控制各种类型的机械或生产过程。、、  Abstract With the accelerated development of Chinas economic and cultural improvement of material living standards prompted the urgent pursuit of higher enjoyment of life pattern fountain in the people around everywhere, such as square, buildings, residential, parks, etc.. So large and small parks have sprung up in the new urban planning, which is bound to build some of the fountain for people to relax, and watch. Pattern fountain is a man-made climate, can play the role of humidification and cooling during the hot summer: water oxygenation, increase in water self-purification capacity, and serve to prevent the role of black-odor water. Synchronized fountain core is PLC, is a microprocessor core, with the instruction memory, and input and output interfaces, a combination of micro-electronics technology, computer technology, automatic control technology, communications technology, a new generation of industrial control devices. It can store and execute instructions, position control, logic control, sequence control, timing, counting and arithmetic operations such as digital and analog inputs and outputs to control various types of machinery or production processes. This design mainly to the programmable controller PLC control functions through the control of each switch, to meet the needs of the people on the visual, realized easily programmable controller to control the function of the pattern fountain, with the wiring is simple, intuitive programming, expansion and so on. Synchronized fountain feature adds only need to increase the function of the corresponding procedures and output changes less debug results show that the adaptability, flexibility, accuracy and reliability, have met the design requirements. With this design, I learned a lot,
