The system comprises a user terminal station, UA-TSN configuration management middleware and a centralized user configuration entity, wherein the user terminal station comprises a plurality of field devices and a UA-TSN coordinator; after embedded OPC UA servers of the devices are registered to the UA-TSN coordinator, the UA-TSN configuration management middleware acquires an OPC UA address information list by means of accessing the UA-TSN coordinator, communicates with the field devices by means of corresponding address information, and collects device information; and the centralized user configuration entity extracts and parses TSN flow demand information aggregated by the UA-TSN configuration management middleware, and performs scheduling calculation by using the information, so as to complete configuration. By means of the present application, the automatic transmission and configuration of TSN scheduling information are realized, thereby alleviating the problem of operation complexity during a large-scale TSN configuration process.
