Abstract:The application of industrial control computer,manmachine interface (MMI),PLC and other functional modules in the control system of sealant internal mixer production line was introduced.In order to achieve the requirements for integration of distributed network control of sealant mixer production line,the design scheme of software and design principle of mixer production of integrated control system of distributed network system were put forward.The practical application proves that the control system of sealant internal mixer improves the functional control,the product quality and producing efficiency of the mixer,and implements intelligent control and information sharing function of the process of internal mixer.
