Abstract
The present invention relates to a cross-network time synchronization method for industrial wireless network and TSN fusion, which belongs to the field of Industrial Internet, comprising the following steps: S1: conducting clock synchronization by a TSN module of a border gateway with a TSN switch of a TSN 2 in a slave clock state; S2: inside the border gateway, using the TSN module as a master clock of an industrial wireless module, and conducting clock synchronization by the industrial wireless module with the TSN module through a serial port; S3: conducting clock synchronization by a routing device in the industrial wireless network with the industrial wireless module of the border gateway through a beacon frame synchronization mode in the slave clock state, and conducting clock synchronization by the routing device as the master clock of a node device for the node device; S4: conducting clock synchronization by a terminal side conversion node in the slave clock state with the node device in the industrial wireless network through a timestamp-free synchronization mode, and finally, synchronizing a TSN switch of a TSN 1 with the terminal side conversion node in the slave clock st…
