1、毕业论文（设计）摘要跟着我国的都会化历程的加快和人丁的多量会聚，环境也是让人们更加的重视了，优良环境能让人的心情更为舒服并能使服务效能升高。此中喷泉也能够润湿四周的空气并能减削尘土同时也可让气温下降。喷泉细小水滴和四周空气份子抨击，也许爆发大批的负氧离子，有利于改良住区的脸蛋和督促住民身心康健。花样喷泉选用可编程控制器PLC和变频器，用器件完成对花样喷泉运转的节制，可信性也大的升高。节制系统布局简易，外面路线简易，便利的增添或变更控制收效，也许实行故障逐动检测与报警闪现出来，升高运转安好性，并便于查验。用SFC法子编程,能够使计划思绪
2、清楚,编程简洁。以其卓越的速度技能逆变器、制动性能、高效率、高功率器件和节能效果，可控制水位的高地喷泉，范围一般是很多其他的优势，被国内和国外公认是最有前希望的速度。于是，可编程控制器技能加变频器变速成了今世喷泉行业的一个多样。这策画是把持PLC和变频器的变速技能，是以有三种喷水的花样可以供选；可以节制每个环喷水管喷水的那个高度；喷水的时候要有灯光表现出来；能够按照分别天色、个别场所可转变喷水的样子。将各类水的形状和灯的光，依照开始制定的序列组合的实行来控制程序的策画，经过计算机地运转来发来控制讯号，使水地形状和灯的光有林林总总的转变
