Leading locomotive operation is a type of common and complex operation at hub stations.A new dynamic management scheme is designed to conduct operation management on the basis of the real-time records of leading locomotives,so as to solve the problems of the existing CTC3.0 system in term of management functions for leading locomotive operation at busy stations,such as frequent manual intervention,complex operations and poor practicability.The real-time record table for leading locomotives is dynamically maintained according to the real-time locomotive number and location at stations and the arriving and departing locomotive information in the train plan.During route setting,the dynamic programming method is adopted to automatically select the optimal running path and assist signalmen in selecting and setting shunting routes,by combing self-learning system path library with manual selection.Field application verifies that the proposed dynamic management scheme is more suitable for the actual requirements of busy stations,and can effectively improve system availability and reduce the workload of station operators.
