摘要
为了改进音乐喷泉的效果,采用PLC多点控制系统代替大量的继电器线路,通过PLC对音乐喷泉控制系统的SSR、彩灯、射灯、水泵的多点控制,编写一些程序和简单的连接实现大量的开关量按照逻辑条件进行顺利动作和进行连锁保护动作的控制。结果表明,PLC的应用不仅能够进行多种水型切换,而且能控制喷泉随音乐上下起伏,同时花式更改方便,SFC编程设计思路清晰。
In order to improve the effect of musical fountain,PLC,multi-point control system,is applied to replace a large number of relay circuits.PLC can control SSR,the colorde lantern,the spotlight and the water pump in musical founain multi-points control system by writing some procedures and simple connections,and carry on the smooth movement and accomplish logic chain of protection for the control of movement according to the logical condition.The result indicates that PLC can not only achieve water-switching,but also control musical fountain up and down with music.The PLC make floral formula change easily and the design of programming SFC is clear.
