Problems solved by technology

However, the current marshalling methods of trains all adopt the fixed-point docking method. The disadvantage of this method is that it takes a long time to stop and a large number of stops, but there are not enough platforms in some small stations to realize the docking of trains. Simultaneous docking of or multiple trains, so it is necessary to reduce the density of train stops, which often reduces the normal transport efficiency of trains
In addition, the process of starting and stopping the train will cause higher energy consumption, so it also relatively increases the operating cost of the train

Embodiment 1

[0042] figure 1 It is a flow chart of a train docking control method provided by an embodiment of the present invention. Please refer to figure 1 , the specific steps of the docking control method of the train include:

[0043] Step S10: Obtain the separation distance between the main train and the docking train in real time.

[0044] Wherein, the main train and the docking train run in the same direction on the same main line, and the main train is the front car of the docking train.

[0045] It can be understood that since the docking between the main train and the docking train is required, the two must run on the same main line and in the same direction. The main train is the front vehicle of the docking train in the direction of travel speed. Under the condition of ensuring the safety of the main train and the docking train, there is no specific limitation on the initial speed of the main train and the docking train.

[0046] Step S11: Judging whether the separation d...

Embodiment 2

[0060] On the basis of the above embodiments, as a preferred implementation manner, the interval threshold is specifically:

[0061] L z =L a +L b +L s +L e ; where L a is the running distance between the start of braking and the effective braking of the docking train, L b is the common braking distance of the docking train, L s is the safe distance between the docking train and the main train, L e is the error distance.

[0062] It should be noted that the interval threshold is at least the distance between the main train and the docking train, and the interval threshold is the distance traveled by the docking train during a series of docking operations. Therefore, in order to ensure that the docking train will not collide with the main train, In order to ensure the safety of the main train, the interval threshold should at least take into account the running distance L between the start of braking and the effective braking of the docking train a , The usual braking ...

Embodiment 3

[0080] An embodiment of a train docking control method has been described in detail above. The present invention also provides a train docking control device. Since the embodiment of the device part corresponds to the embodiment of the method part, the device part For the embodiments, please refer to the description of the embodiments in the method part, and details will not be repeated here.

[0081] Figure 4 It is a structural diagram of a train docking control device provided by an embodiment of the present invention. Such as Figure 4 As shown, a docking control device for a train provided in an embodiment of the present invention includes:

[0082] The obtaining module 10 is used to obtain the separation distance between the main train and the docking train in real time.

[0083] The first judging module 11 is used to judge whether the separation distance is less than or equal to the separation threshold, and if so, execute the setting module 12 .

[0084] The settin...

Abstract

The invention discloses a train docking control method, device and medium. The method includes the following steps that the spacing between a main train and a docking train is obtained in real time, wherein the main train and the docking train drive in the same direction on the same main line, and the main train is the power train of the docking train; whether the spacing is smaller than or equalto a spacing threshold; if yes, a speed change rule is set, wherein the speed change rule refers to the positive correlation between the speed of the docking speed and the spacing; according to the speed change rule, the docking train is controlled to catch up with the main train to dock with the main train. It can be seen that the method can achieve the smooth docking between the two trains whenthe two trains are in drive, the overall transport efficiency is improved, energy consumption is reduced, and the operation cost of the train is reduced. In addition, the invention further discloses the train disengagement control device and medium, and the beneficial effects are as described above.

Description

technical field [0001] The invention relates to the field of rail transportation, in particular to a method, device and medium for controlling the docking of trains. Background technique [0002] With the continuous development of rail transit, more and more people choose to use rail transit to travel, which puts forward relatively high requirements for the current capacity of rail transit. [0003] Combining trains is an effective measure to increase the capacity of existing railways. According to the experience of various railway bureaus, running combination trains on busy lines can increase line capacity by 30%-40%. However, the current marshalling methods of trains all adopt the fixed-point docking method. The disadvantage of this method is that it takes a long time to stop and a large number of stops, but there are not enough platforms in some small stations to realize the docking of trains. Or the simultaneous docking of multiple trains, so it is necessary to reduce ...
