Study And Design Of DCS Mixture Monitor System Based On PLC And Kingview

In the current field of domestic chemical production, the controlling of producing wet ingredients mostly using local instrumentation combined with scene work to achieve the monitoring. In this case of the monitoring, the labor intensity is large, the working environment is harsh, the detection and repairing time is very long, the process of precision is not up to standard. So it often has low productivity and poor product quality. This paper proposed a corresponding solution based on the process flow and requirements of production according to the project of Wet Resin Ingredients System commissioned of Amway synthetic leather Limited by Share Ltd.Based on the actual requirements of producing wet resin ingredients, combining the control object and requirements of industrial production scene work, with rigorous and stable design ideas, we finalized the DCS control system solutions based on PLC and Kingview. This design’s hardware includes the design of power distribution circuit, design of kettle motor control circuit, design of the scene pumps and valves circuit and so on. We use S7-300PLC as the core of control system. Configuration software King View is used to design the system of man-machine interface. Industrial Ethernet is used to communicate PLC and DPC. What’s more, creatively combing the scene choice of materials combines and the operator station control, Simplicity and safety what the production process requires is combined together in the requirements of control system.The production monitoring system of wet resin ingredients has been put into production. Up to the present, the production process ran safety and the system ran stable. It greatly enhanced and developed the automation and visualization of producing wet resin ingredients. It improved product quality and production efficiency. And it meets customer needs.
