Abstract

Abstract: As When the braking deceleration performance curve of trains need to be processed in a segmentation and approximation way, the braking curves of different types of trains are quite different, there is no unified braking curve segmentation scheme. This paper proposes a method of train braking curve segmentation based on particle swarm optimization. This method takes the braking segment point as the optimization parameter and the braking distance as the optimization target, which can realize the optimal approximation of any segment of the train braking curve. Since this method has nothing to do with the type of train, the shape of the braking curve, and the number of segments, it can be applied to the braking curve segmentation of all kinds of trains and has good application value

Key words: train control system, automatic train protection, particle swarm optimization, braking curve, electric multiple unit

摘要： 针对列车制动减速性能曲线进行分段近似处理时，遇到不同类型的列车制动曲线差别较大，没有统一的制动分段方法的难题，提出一种基于粒子群优化的列车制动曲线分段方法。该方法以制动分段点为优化参数，以制动距离为优化目标，可实现列车制动曲线的任意段最优近似。由于该方法与列车类型，制动曲线形态，分段个数均无关，因此可应用于各类车型的制动曲线分段，具有很好的应用价值
