Therefore, the method is to firstly judge whether the original file needs to be updated or not based on the relationship between the updated file and the original file box of the updated file box, and in the judging process, the method is based on the relationship between the active characteristic of the updated file and the original configuration file, and only H (i) is more than or equal to 1, which indicates that the updated file needs to be updated; h (i) < 1, indicating no need for updating. When the updating is needed, whether the updating can be carried out or not is judged, because the control box does not know one, the updating sequence is fast or slow, and even some configuration files are updated, the Euclidean distance is introduced, and the original files and the content are judged to be incapable of being updated based on the exponential function. And the last step is to realize updating based on the updating model, and further judge that the dynamic updating can not be continued according to the updating result, and when the K is 0, the control box can perform dynamic updating. When K is greater than 0, the control box does not need to be updated; and when K is less than 0, the updated content has interference data packets.
