The design of living area of water supply monitoring system based on Kingview

Abstract:With the social and economic development, urban construction and development is very fast, and the infrastructure has put forward higher requirements. People on the reliability of water quality and water supply systems continues to increase. The use of advanced automation technology, control technology and communication technology to design high-performance, energy-efficient water technology has become an inevitable trend.

     The design of the core Kingview monitoring, surveillance system and two-site operation box can be controlled, it can be automatically switched hand, local and remote switches. Intuitive configuration screen, you can display the pipe network pressure and pump operation. Sampling and control signal measurement signals output by the PLC module, between the computer and PLC communication modules implement the transmission of information to Kingview software platform control software and PC management software, to achieve the living quarters of the water flow control. Due to the design application Kingview monitoring software, the use of technology-based programming configuration Kingview and inverter control constant pressure water supply systems, energy efficient, automatic, reliable, easy maintenance, easy management advantages

Keywords:  Kingview; PLC; water supply control system
