Method and device for continuous calculation of train running speed curve

Abstract

The invention discloses a method and device for continuously calculating the speed curve of a train to realize the purpose of automatically and continuously calculating the speed curve. , for at least one calculation interval, perform the following overspeed processing steps, including: judging whether there is an overspeed interval whose speed exceeds the speed threshold range corresponding to the first calculation interval in the first speed curve of the first calculation interval; if it exists, find Exit the end point of the speed limit interval towards the starting point of the operation, calculate the first speed limit value that the train should reach when passing the end point, recalculate the first speed curve of the train passing through the first calculation interval, and return to judging whether the first speed curve is There is a step of exceeding the speed limit interval in which the speed exceeds the speed threshold range corresponding to the first calculation interval; if not, start to calculate the speed curve of the next calculation interval of the first calculation interval.

Description

technical field [0001] The invention relates to the field of train running simulation, in particular to a method and device for continuously calculating train running speed curves. Background technique [0002] In the construction of rail transit, in order to give full play to the running quality of the train, it is necessary to simulate the running of the train and calculate the speed curve of the running of the train. [0003] At present, before calculating the speed curve of the train, the speed limit point and the speed corresponding to the speed limit point will be preset according to the route situation, and then the entire operation interval will be divided into various calculation intervals according to the preset speed limit point. The speed at the end point of the interval will be used as the starting speed of the next calculation interval of the calculation interval to calculate the running speed curve, so as to calculate the speed curves of each calculation inter...

Problems solved by technology

[0004] However, if the speed curve is calculated only based on the preset speed limit point and speed limit value, in the case of insufficient train braking force (for example, a long downhill slope), there will be an area exceeding the speed limit in the speed curve of a certain calculation interval. Happening

Since the existing technology only calculates the speed curve according to the preset speed limit point and speed limit value, if you want to correct the speed curve in this calculation interval without affecting the accuracy of the speed curve in the next calculation interval of this calculation interval, at this time You can only interrupt the calculation, manually modify the preset speed limit point and the preset speed limit value, and recalculate the speed curve of the calculation interval

Therefore, the existing technology cannot automatically and continuously calculate the speed curves of each calculation interval where the speed does not exceed the speed limit, which not only wastes manpower but also has low efficiency
