Taking flexible manufacturing systems as the application scenario,a cloud platform information collection system was proposed utilizing OPC UA technology to integrate production process data with multiple interface protocols such as TCP/IP Ethernet and Modbus.The characteristics of current cloud platforms were analyzed.Based on the analysis,the overall structure of the cloud platform suitable for data collection was designed.A real simulation system was built using simulation software based on the on-site environment.Finally,an OPC UA server was built using the industrial software KEPServerEX,and the OPC UA client was developed on the.NET platform using C# programming language,with corresponding functional blocks designed.Finally,the collection and management of flexible manufacturing system data information was achieved by using the cloud data management platform.
