High-speed train dynamic scheduling and operation control collaborative optimization method and system

The invention discloses a high-speed train dynamic scheduling and operation control collaborative optimization method and system, and relates to the technical field of high-speed train dynamic scheduling and operation control. The method comprises the following steps: 1, acquiring train operation information of a dispatching section; 2, establishing a train dynamic scheduling model which comprises a train scheduling objective function and constraint conditions; 3, solving a dispatching scheme of train dynamic dispatching by utilizing an ant colony algorithm to obtain an adjusted actual working diagram; 4, generating a feasible optimized speed position curve according to the adjusted actual working diagram, interval basic conditions and train basic parameters; and 5, tracking the optimized speed position curve. The method can achieve the dynamic scheduling of train delay, generates a new scheduling scheme, executes the scheduling scheme through the operation control module, reduces the train delay time, recovers the normal operation of a train, breaks through the boundary of a dynamic scheduling system and an operation control system, and achieves the integrated cooperation of dynamic scheduling and operation control.
