Abstract:In order to realize the monitoring of the production process of composite filament winding machine,taking the winding machine and its auxiliary equipment as the research object, aiming at the diversity of actual processing equipment and the heterogeneity of processing data collection,the winding machine architecture model was established based on OPC UA.According to the OPC UA specification issued by the OPC Foundation and relevant industry standards,the information model and instantiation of filament winding machine system were established.Based on the open-source project open62541,the compiled information model code of the winding system was imported,a specification-compliant OPC UA server was customized and developed ,and then the UA client was used to connect the server.The client could query the processing data of the system through the server,the heterogeneity problem of processing data was solved,and the purpose of monitoring the production and processing process of the winding machine was realized.Finally,it is verified that the established fiber winding machine information model can be correctly imported into the open-source project open62541 and the processing data monitoring is realized.
