Claim 6:
7. The OPC UA-based centralized user configuration method for a time-sensitive network according to claim 5, wherein the communication between the UA-TSN configuration management middleware and the UA-TSN coordinator is that the communication between the UA-TSN configuration management middleware and the LDS-ME discovery server in the UA-TSN coordinator through a user device discovery module, the discovery process between the user device discovery module and the LDS-ME discovery server comprising the following steps:
creating a second OPC UA server for the user device discovery module, initializing the configuration, performing multicast domain name system (mDNS) service, setting an application type and URL information of the second OPC UA server, randomly allocating a server port number, and adding server information,
starting the second OPC UA server and waiting for LDS multicast discovery, and calling a corresponding callback function when other new LDS-ME discovery server is discovered through mDNS multicast, to obtain URL information and port information of the new LDS-ME discovery server, and
checking whether the new LDS-ME discovery server supports signature and encryption, calling a function to generate a corresponding second registration client, connecting the second OPC UA server to the new LDS-ME discovery server, and registering, by the second OPC UA server, with the new LDS-ME discovery server.
