Similarly, when the linkage group display adjustment instruction is sent, some sending cards cannot receive the linkage group display adjustment instruction due to factors such as network states, and therefore, the embodiment of the application also sets a repeated sending mechanism for the linkage group display adjustment instruction. Meanwhile, in order to prevent the sending card from repeatedly executing the same linkage group display adjustment instruction and improve the efficiency of grouping control, after step S203 is executed, steps S206 to S207 need to be executed, please refer to fig. 6, and steps S206 to S207 are specifically as follows:
