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 e
