Abstract: In order to solve the problem of data collection and unified monitoring caused by various industrial equipment protocols,a data collection system based on OPC UA is studied.Taking industrial equipments,such as PLC,industrial robot and CNC machine tool as research object.Connection between industrial equipment and local monitoring server is established through industrial Ethernet.On the local monitoring server,different data acquisition drivers and data conversion plug-ins are designed and unified management according to different industrial equipment communication protocols.Based on the OPC UASDK and the XML file generated by the configuration interface,the OPC UA address space is constructed to build the OPC UA server,which is used to store the converted data and interact with the OPC UA client.Meanwhile,the collected converted data is uploaded to the cloud storage system for further data analysis.The system is developed based on .net platform,using C# language and .net framework to build the whole local monitoring server,using WPF to design the monitoring and configuration interface of the local monitoring server.The cloud combines Redis and MySQL to realize the storage of operating data.Finally,the feasibility and integrity of the system are verified through experiments.

Key words: .Net, Data collection, Industrial equipment, OPC UA, Redis
