Zusammenfassung:The invention provides a time synchronization method for EtherCAT and 5G fusion networking, and belongs to the technical field of industrial internet and 5G fusion. The method comprises the following steps: adding a time delay measurement module in an EtherCAT and 5G fusion networking architecture, and detecting 5G network time delay through the time delay measurement module; according to the detected 5G network time delay, the time delay measurement module sends a time delay compensation value to an EtherCAT master station of each network segment, the master station sends a master station clock after time delay compensation to a first slave station of the network segment of the master station, and other slave stations carry out offset compensation and static drift compensation according to the first slave station clock; and the dynamic synchronization process is circulated subsequently, and the time delay measurement module dynamically detects the time delay change condition of the 5G network, so that the dy
