The invention relates to an automatic designing and generating system for a carrier rocket flight time sequence, and belongs to the field of spacecraft electrical system automation design. Standard automatic output of the flight time sequence is achieved, the problem that manual design errors are easy to brought in when a sequence chart is drawn manually is avoided, and the design efficiency is improved; battery analysis and interpretation data automatic export functions are provided, so that the reliability of interpretation and reexamination is strengthened; management on the flight time sequence of rockets with different types, states and launching times is achieved through a database, the repeated work is reduced, and the control on the technical state change of the flight time sequence is achieved reasonably and effectively.
