Claim 7:
8. The OPC UA-based centralized user configuration method for a time-sensitive network according to claim 5, wherein the UA-TSN configuration management middleware is connected to a plurality of field devices in the user terminal station and communicated with embedded OPC UA servers of a user device through the user data aggregation module, the communication process between the user data aggregation module and the embedded OPC UA servers comprising the following steps:
creating and initializing a third OPC UA server in the user data aggregation module, and adding required nodes and references to address spaces of the third OPC UA server;
starting the third OPC UA server, and creating a new OPC UA client to call a corresponding callback function, to obtain an address information list of the embedded OPC UA servers of the user terminal station;
creating and initializing a plurality of OPC UA clients according to the obtained address information, connecting the OPC UA clients to corresponding embedded OPC UA servers according to URL address information, reading, by the OPC UA clients, data of the embedded OPC UA servers, and writing the data into the address spaces of the third OPC UA server; and
interrupting the data interaction when the third OPC UA server receives a stop signal, disconnecting the communication connection between the OPC UA clients and the embedded OPC UA servers, and stopping the third OPC UA server and releasing the address spaces of the server.
