Automatic generation method and system for adjusting running diagram at equal intervals

The invention discloses a method and a system for automatically generating an equal-interval adjustment working diagram. The method comprises the following steps of: 1) calculating to-be-adjusted duration of a train; 2) generating a prediction plan line of each train; (3) adjusting times C = 0; 4) adding 1 to the adjustment times; 5) calculating adjustable factors of the task lines in the prediction plan lines, and selecting the task line with the maximum adjustable factor; (6) the arrival and departure time of each station in the selected task line is adjusted, so that the to-be-adjusted duration of the corresponding train tends to be 0; (7) judging whether an unprocessed task line exists or not, and if so, returning to the step (5); otherwise, next step; 8) judging whether the arrival and departure time of the station on any task line is changed or not; if so, the next step is carried out; and (9) judging whether the adjustment frequency C is smaller than the maximum adjustment frequency Cmax, and if so, ex
