To solve the problems of data acquisition,visualization,remote monitoring and management of production equipment in manufacturing enterprises,a remote visualization system of small manufacturing units in manufacturing enterprises based on B/S architecture was designed.Through the deep analysis of data acquisition and remote visualization in the production process of enterprises,the overall communication technical framework of remote visualization monitoring system was designed.The remote visualization system of small manufacturing cell based on B/S architecture was realized by using OPC and SQL technology.The system is composed of functional modules such as equipment status,storage management and operation monitoring.It intuitively reflects the equipment,storage and production of the manufacturing unit through charts,and greatly improves the management level in the production process of the enterprise through the visualization system.
