Train operation control method and system

Abstract

The embodiment of the present invention provides a train operation control method and system, by determining the set of alternative routes, and determining the route with the longest running time of the exit route from the set of alternative routes as the current running route of the train, providing A method for determining the train running path under the condition that all incoming tracks cannot be delivered is proposed. Moreover, based on the ATO command speed curve of the route with the longest running time, the target running time of the train between the starting station and the arriving station, and the longest running time of the route, it is determined that the train has the longest running time on the route The running speed on the incoming road can ensure the punctuality rate of the train, and at the same time expand the speed processing capacity of ATO. In the embodiment of the present invention, the ATO performs train operation control according to the target running time issued by the ATS, and can realize energy-saving operation at a time close to the operation plan under the premise of ensuring comfortable control of the train.

Description

technical field [0001] The invention relates to the technical field of urban rail transit, and more specifically, to a train operation control method and system. Background technique [0002] In the current fast-paced social environment, the punctual arrival of rail transit trains is very important, and the trains need to strictly implement the operation plan of the Automatic Train Supervision (ATS), that is, the train schedule. [0003] At present, the operation plan of the ATS can be delivered to the automatic train operation system (Automatic Train Operation, ATO) through the operation level. The running level is the speed percentage. After receiving the running level issued by the ATS, the ATO adjusts the running speed according to the speed percentage corresponding to the running level, and adjusts the running time in a disguised form. Domestic ATS usually adjusts the operation plan by adjusting the operation level issued to ATO. The ATS determines the operation time c...

[0004] However, the ATS in the prior art adjusts the operation plan by adjusting the operation level. It is necessary to estimate the operation time corresponding to a certain operation level and determine it after multiple adjustments. The process is relatively complicated.

Moreover, the operation level is discrete, and the operation time needs to be optimized when corresponding to the operation level. This approach is also likely to cause late and early trains

Using the running level is blunt Applying the speed percentage to the speed curve, it is inconvenient to adjust the speed limit according to the specific situation of the train
