N2 - In the field of information and communication, data model is used to describe the data organization form of information. It is the pilot work to establish the corresponding database. In Space Environment Simulation and Research Infrastructure, the form of data is various. This article first analyzes the data needs to be collected and a unified data model for monitoring based on the Space Environment Simulation and Research Infrastructure is established; Secondly, the adaptability of the unified data model to the Space Environment Simulation and Research Infrastructure was analyzed and the data conversion plan of the non-unified data model was designed; Finally, UaModeler is used to model the constructed unified data model for OPC UA information, and the communication protocol efficiency is calculated according to the OPC UA communication protocol mapping process. The results show that the model has good scalability and versatility. The data carried by the model can provide effective support for the experimental monitoring function of the Space Environment Simulation and Research Infrastructure. The OPC UA protocol can further realize the interoperability between devices on the basis of the use of a unified data model, and has a higher efficiency in multi-data transmission with a small amount of data, and meets the communication requirements of the Space Environment Simulation and Research Infrastructure.
