Abstract

The invention discloses a train multi-interval operation curve rapid optimization method. The method comprises the steps that S1, data, including train parameters, line data and whole line operation time, of a train number model to be optimized are acquired; S2, setting speed curve optimization parameters; S3, preprocessing the train parameters and the line data in the step S1; S4, calculating thestate space, the state transition equation and the state transition cost in each interval; S5, connecting the state spaces of the intervals into a whole, and performing dynamic programming algorithmsolution in combination with a weight adaptive adjustment method to obtain a dynamic programming optimization result under the constraint of the whole line operation time; and S6, analyzing and outputting a dynamic planning optimization result to obtain a multi-interval energy-saving operation speed curve and the distributed operation time of each interval.

Description

technical field [0001] The invention belongs to the technical field of train operation curve planning, and in particular relates to a fast optimization method for train multi-section operation curves. Background technique [0002] As an important means of transportation, trains are constantly improving both in terms of speed and density, and are playing an increasingly important role in the national transportation field. As a large-capacity passenger transportation tool, how to ensure the safe and comfortable operation of trains is an important issue. On the other hand, due to the huge economic cost of train traction energy consumption, the issue of energy-saving maneuvering is also a research hotspot in this field. And all of this must be based on the punctual operation of the train to realize the efficient transportation of the entire line. [0003] In the traditional manual driving mode of trains, the driver formulates a rough interval operation plan based on the curren...
