基于PLC变频恒压供水监控系统设计

Design of Water Supply in Constant Pressure and Frequency Conversion Based on PLC

由计算机、PLC、变频器构成智能变频控制系统,取代水塔、水箱、气压罐等设备,调节水泵的输出流量,实现恒压供水的节能目的。论文重点介绍了变频恒压供水系统的设计和PLC与上位机的数据交换的通讯实现。

For saving energy to keep water supply in constant pressure, we adopt a intelligent control system composed of PC, PLC and transducer, instead of water supply equipment such as water tower, water tank ect. The design of water supplying system with constant pressure and data exchanging between PLC and PC are presented in the paper.
