1. An open platform communications unified architecture (OPC UA)-based centralized user configuration system for a time-sensitive network, at least comprising user terminal stations, a unified architecture-time-sensitive network (UA-TSN) configuration management middleware and a centralized user configuration entity, the user terminal station comprising field devices adopting different industrial protocols and a UA-TSN coordinator, the UA-TSN configuration management middleware obtaining an OPC UA address information list by accessing the UA-TSN coordinator after embedded OPC UA servers of the field devices in the user terminal station actively register with the UA-TSN coordinator, the UA-TSN configuration management middleware communicating with the field devices in the user terminal station through corresponding OPC UA address information and collecting device information, the centralized user configuration entity extracting and analyzing time-sensitive network (TSN) stream demand information aggregated in the UA-TSN configuration management middleware, and the TSN stream demand information being scheduled and calculated to complete configuration,
the process of the embedded OPC UA servers of the field devices in the user terminal station actively register with the UA-TSN coordinator comprising the following steps:, creating embedded OPC UA servers according to first registration information required by the embedded OPC UA servers, and initializing the configuration,
defining an analytic function and a reading and writing method of data source information, and constructing address spaces of the embedded OPC UA servers according to the reading and writing method of data source information,
calling the analytic function to process data, and adding the processed data information to nodes corresponding to the address spaces of the OPC UA servers,
starting the embedded OPC UA servers to collect data information of the field devices, and calling the analytic function to obtain dynamic data of the field devices,
creating a first registration client and initializing the configuration of the first registration client, and
starting the first registration client and querying a local discovery server-multicast extension (LDS-ME) discovery server in the UA-TSN coordinator, and completing, by the embedded OPC UA servers, registration in the LDS-ME discovery server after the first registration client queries the LDS-ME discovery server.
