摘要
介绍了一种基于西门子PLC的风机变频调速系统,是在工业控制网络实验室设计并实现成功的。该系统中,上位机采用西门子WinCC组态软件实现监控,下位机采用S7-400控制器,同时选用了ABB变频器。通过PLC算法实现的过程,比较变频控制与风门控制效果明显的区别,提出了风机变频调速系统的优越性。
This paper introduces a speed converting system of fan based on siemens PLC,which is realized in the industrial controlling network laboratory.In this system,the PC uses the configuration software——WinCC to watch and control,the bottom uses the advanced S7-400 controller,in addition of ABB converter.In the realization process of the PID Arithmetic,we compare the controlling effect of converter and fan.We find that converter is more excellent than fan.
