Internet is one of the important network carriers of the industrial Internet of Things. Because of its dynamic changes, the path will expire when supporting the transfer of group control commands, which cannot achieves collaborative manufacturing to equipments scattered in different regions. This paper transformed the group control command transfer problem into constrained dynamic multi-Steiner trees problem firstly, and proposed a kind of improved dynamic genetic algorithm. The algorithm proposed a hybrid search strategy with static and dynamic dimensions. It executed static search strategy when network state didn' t change, static search strategy mainly considered alleviating premature phenomena. It executed dynamic search strategy when network state changed, dynamic search strategy mainly considered improving convergence and using static search strategy to alleviate premature phenomena. This paper verified the validity, convergence and global search ability of the algorithm from transfer success rate, convergence delay rate. [ABSTRACT FROM AUTHOR]
