基于PLC的景观建筑供水水泵控制系统设计

Design of water supply pump for landscape architecture based on PLCAbstract:With the continuous improvement of people's living environment,the construction of the city isbecoming more and more beautiful.Waters cape has become a beautiful landscape in people's life.In largeparks,squares and scenic spots can be seen everywhere,but the size,control methods are different.This designis a construction waterfall water supply pump design,in this design,the use of PLC,frequency converter,thepump frequency conversion control.The annoying control of this design is to control the waterfall size by music.The application of PLC and theaudio signal is converted into a pulse signal,then input to the inverter,the inverter output frequency varieswith the audio signal,so that the pump speed,change the water supply reached the waterfall with the music tothe change of size.This uses frequency conversion speed regulation.Frequency of its excellent performance and the speed of braking performance,high efficiency,high powerfactor and energy saving effect,wide application range and many other advantages of being recognized as themost promising way to speed.Therefore,the use of PLC control pump water supply has become convenientand efficient.Key words:Motor,Variable frequency starting;PLC
