Title:
TIME DIVISION CONTROL BASED ENERGY-SAVING OPERATION METHOD AND APPARATUS FOR TRAIN
Document Type and Number:
WIPO Patent Application WO/2023/216441
Kind Code:
A1
Abstract:
The present invention provides a time division control based energy-saving operation method and apparatus for a train. The time division control based energy-saving operation method for a train comprises: determining a target route section of the a train between adjacent platforms; determining, on the basis of the target route section, a ceiling speed curve and a target speed curve of the train operating in the target route section; determining a target coasting section from the target route section on the basis of the ceiling speed curve and the target speed curve, the target coasting section corresponding to a target coasting threshold; generating, on the basis of the target coasting section, the ceiling speed curve, and the target speed curve, a target control instruction for controlling the operation state of the train. According to the time division control based energy-saving operation method for a train of the present invention, a train speed can be globally and dynamically planned, strong adaptability, a small calculation amount, high calculation accuracy and high smoothness are achieved, and the efficiency of generating an energy-saving operation speed curve of the train is effectively improved; energy consumption can further be effectively reduced, so that energy saving and punctual operation are both achieved.
