摘要针对传统的喷泉控制系统一旦设计好控制电路,就不能随意改变喷水花样及喷水时间等问题, 本设计结合西门子 S7-200 可编程控制器设计能适应不同季节、不同场合的喷水要求目的的花样喷泉系统。该花样喷泉控制系统不但实现了自动转换花样喷泉的喷水样式,而且提高了系统的可靠性和安全性,具有一定的工程应用和推广价值。关键词: PLC ;花样喷泉;控制系统 The pattern design based on PLC fountain Abstract According to the traditional fountain control system design control circuit, if cannot change pattern and spray water, time, etc. This design with Siemens S7-200 PLC design can adapt different season, the different requirements of the water fountain system designs purpose. This figure fountain control system not only realizes the automatic conversion pattern of the fountain of the water, and improve the system of style, the reliability and safety of engineering application and dissemination value. Key words : PLC control , pattern fountain system 目录摘要......................................................................................................................................................
