AbstractWhat is a music fountain?Music fountain is the fountain that will playmusic,and at the same time,the light of the fountain and the form of fountainfountain water will change with the rhythm of music.It can not only bring peoplevisual enjoyment,but also bring people auditory feast.It is the combination oflandscape and art.And with the continuous progress of the times and the continuousdevelopment of the economy,people's living standards are also improving year byyear.People are no longer just pursuing material prosperity,but also graduallybeginning to seek spiritual satisfaction.So music fountain,which can beautify theenvironment,but also bring people double enjoyment of vision and hearing,isrespected by modern people.Through our research and analysis of music fountain,we find that themodern control system of music fountain is not perfect.It has two disadvantages.Oneis the former control system of music fountain.It is to amplify the frequency of themusic and then control the solenoid valve or water pump when the music is playing.Then the water flow will flow from the music fountain.Sprinkler spray out,whichwill lead to the music and fountain spray out of sync,that is,when the fountain sprayreaction rate can not keep up with the rhythm of music,for example,the fountain isequivalent to a total of singers out of tune,singing will never be tuned up.The secondis the former music fountain,the fountain pattern is very few,very single,is a music,only a set of corresponding fountain pattern,and as long as the fountain form of thissong once formed,it can not be changed.In this paper,the above two issues are studied and discussed,and a musicfountain control system based on PLC and frequency converter is designed.Theoverall structure of our design is composed of console and server software.Our musicfountain control system based on PLC and frequency converter,in addition to havingthe original function,we still need to solve the problem that the fountain can not keepup with the music rhythm when spraying through multi-sound card technology
