The invention belongs to the technical field of rail transit, and particularly relates to a train traction calculation method and device based on interval speed limit correction. Under the service braking performance of the train, the maximum allowable speed of each speed limiting starting point in the current position and the follow-up set range is calculated in an iterative mode, it can be guaranteed that overspeed does not occur at the next speed limiting starting point after service braking is conducted at the current position as long as the speed of the train is controlled not to exceed the maximum allowable speed of the current position, and the speed limiting effect is guaranteed. And the overspeed is avoided in the subsequent speed limit interval. In the whole iteration process, automatic iteration can be completely achieved through the algorithm, and manual repeated attempts are not needed. The technical problem that in the prior art, the overspeed problem can be avoided only by manually trying to adjust the calculation step length for multiple times is solved.
本发明属于轨道交通技术领域,具体涉及一种基于区间限速修正的列车牵引计算方法和装置。本发明在列车常用制动性能下,迭代计算当前位置以及后续设定范围内的每个限速起点的最高允许速度,只要控制列车速度不超过当前位置的最高允许速度,就能保证在当前位置进行常用制动后,在下个限速起点处不产超速,并且在后续的限速区间内也不超速。在整个迭代过程中可完全由算法自动迭代,无需手工多次尝试。本发明解决了现有技术中需要手工多次尝试调整计算步长,才有可能避免超速问题的技术问题。
