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，围一般是很多其他的优势，被国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。

With the acceleration of the urbanization process of our country and population of a large number of convergence, the environment is being more and more important, a good environment can make the psychosomatic more fortable, increase work efficiency. The fountain in the wet surrounded by air, can also reduce and amend dust, falling the temperature. Fountain of tiny water droplets to air part, perhaps outbreak of a large number of negative oxygen ions, is advantageous to the improvement of munity face and urged residents physical and mental health.
fancy fountain chooses programmable controller PLC and frequency converter, using software to plete the automatic control of the fancy fountain, reliability is greatly increased. Control system layout is simple, simplify the external line and can be convenient to add or change control results, perhaps implements automatic fault detection and alarm, higher safety, operation and convenient for inspection. Using SFC programming way, programming simple. With its excellent speed skills inverter, braking performance, high efficiency, high power device and the energy saving effect, can control the water level high fountain, range is usually a lot of other advantages, is considered by domestic grandpa the speed of the most promising. So, programmable controller PLC skills and frequency converter speed regulation technology has bee a focus in the modern fountain industry.
This policy is the control of PLC and frequency converter speed control skill, and is based on three kinds of water spray pattern to choose from; The height of the water can control each ring spray pipe; A light when spraying performance; Can according to the climate, different places will change the pattern of water. Will all kinds of water type and light, according to the preset plotting the permutation and bination of control procedures, operating through the puter program signal from control, make the plain shape and the light of the lamp has many changes.
Key words: programmable controller PLC; Fancy fountain; Ladder diagram; Frequency converter; Control; The water pump
