Application of the S7-200PLC and KINGVIEW6.53to the constant pressure water supply system with variable frequency

摘要

With the rapid development social economy, on one hand, people's request to enhance the quality of water supply and the water supply system reliability is increased continuously. The design of the system is the VF water supply systems that controlled by PLC of Siemens S7-200 series and Kingview software.and have developed good operation management interface using Supervision Control and Data Acquisition. The operation results show that this system have constant water pressure, simple structure and high reliability.
