Embodiment 1

[0086] Embodiment 1 of the present invention provides a train control method. figure 1 It is a schematic flowchart of the train control method provided by Embodiment 1 of the present invention. Such as figure 1 As shown, the method in this embodiment may include the following steps:

[0087] Step 101. When the train is in the acceleration phase, if it is detected that it needs to enter the deceleration phase, enter the transition phase from the current acceleration phase.

[0088] Step 102, enter the deceleration phase after running for a preset time in the transition phase.

[0089] Wherein, the transition stage operates in an idle mode.

[0090] The method in this embodiment can be applied to the automatic driving process of the train. The execution subject of the method in this embodiment may be the vehicle controller. During the operation of the train, it may go through multiple stages such as acceleration and deceleration. In each stage, the on-board controller can c...

Embodiment 2

[0102] Embodiment 2 of the present invention provides a train control method. In this embodiment, on the basis of the technical solution provided in Embodiment 1, the judgment of the train control level is added, and the transition stage is entered only when the level is relatively large.

[0103] figure 2 It is a schematic flowchart of the train control method provided by Embodiment 2 of the present invention. Such as figure 2 As shown, the method in this embodiment may include the following steps:

[0104] Step 201. When the train is in the acceleration phase, if it is detected that the train needs to enter the deceleration phase, obtain the current train control level of the train.

[0105] Step 202, judging whether the vehicle control level is greater than a preset level threshold.

[0106] Step 203, if greater than, enter the transition phase from the current acceleration phase.

[0107] Step 204, enter the deceleration phase after running for a preset time in the ...

Embodiment 3

[0116] Embodiment 3 of the present invention provides a train control method. This embodiment subdivides the deceleration stage into the target point deceleration stage and the stop point deceleration stage on the basis of the technical solutions provided by the above-mentioned embodiments, and adds other stages of train operation to control the train more comprehensively.

[0117] Specifically, if other conditions are met, if the priority speed reduction point in front is the speed limit descent point or the end point of the movement authorization, then it is determined that it will enter the target point deceleration stage; if the priority speed reduction point is a parking point, then it is determined that What will enter is the deceleration phase at the parking point.

[0118] When it is detected that it is necessary to enter the deceleration stage of the target point or the deceleration stage of the parking point, the vehicle control level can be judged. If the level is l...

Abstract

The invention discloses a train control method and device. The train control method comprises the following steps that when a train is in an acceleration phase, if it is detected that the train needsto enter into a deceleration phase, the train enters a transition phase from the current acceleration phase; and after the train runs in the transition phase for a preset time, the train enters the deceleration phase, wherein the train runs in an idle running mode in the transition phase. The train control method and device can avoid the sudden change of the train from acceleration to deceleration, effectively ensure the smooth running of the train, reduce energy consumption, and enable passengers to be buffered when the acceleration and the deceleration are alternated, thereby improving the riding comfort.

Description

technical field [0001] The invention relates to the technical field of train control, in particular to a train control method and device. Background technique [0002] With the continuous development of science and technology, the operation of trains is becoming more and more intelligent. The automatic driving algorithm of the train can control the running direction, running interval and running speed of the train to ensure the safe and efficient operation of the train. [0003] The traditional automatic train control is mainly based on the ATO (Automatic Train Operation, automatic train operation) speed limit and the automatic control algorithm of the train and the installation of a fixed traction, coasting, braking vehicle control model to carry out automatic driving control on the train, which causes In addition, the speed control is too rigid, and the number of sudden acceleration and deceleration is too many, which is not conducive to the smooth operation of the train, ...
