Disclosed is an OPC UA-based centralized user configuration method and system for a time-sensitive network. The system includes user terminal stations, a UA-TSN configuration management middleware and a centralized user configuration entity. The user terminal station includes a plurality of field devices and a UA-TSN coordinator; the UA-TSN configuration management middleware obtains an OPC UA address information list by accessing the UA-TSN coordinator; and the centralized user configuration entity extracts and analyzes TSN stream demand information aggregated in the UA-TSN configuration management middleware. According to the present disclosure, the automatic transmission and configuration of TSN network scheduling information are realized, and the operation complexity in the large-scale TSN network configuration process is reduced.

The present invention relates to an IPv6 wireless sensor network node mobility management method based on RPL routing protocol. The present invention achieves the following: first, placing an RSSI in an ACK frame so as to detect the mobile state of a node and improve the accuracy of mobile detection; second, on the premise of compatibility with an original RPL routing protocol, improving the options for DIS and DAO in selecting the optimal parent node and updating a routing table; and finally, designing a cache method to prevent messages sent to the mobile node from being lost in the process of moving, and designing a new 6LoWPAN header so as to complete message caching.
