Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 1 is a flowchart of a method for switching a virtual hitching mode of a train according to an embodiment of the present invention, and as shown in fig. 1, the method includes:
step S01, a hitching plan and a hitching area are set according to the current passenger flow information of each platform.
In order to be able to adapt to different passenger flow quantities in different areas and different time periods, the passenger flow volume can be adapted in a way that a large consist train and a small consist train are combined to improve the service quality. The embodiment of the invention provides a combination of a virtual coupling technology and a Train automatic Control System (CBTC) Based on wireless Communication, and forms corresponding mixed running operation of multi-marshalling trains to improve the passenger transport efficiency by analyzing the passenger flow of each station of the whole line in each time period.
And estimating the requirements of each platform on a large marshalling train and a small marshalling train in different time periods according to the acquired passenger flow information of each platform in advance. The large train set can be achieved by virtually linking a plurality of small train sets to form a linked train, and the number of the small train sets corresponding to each large train set can be set according to actual needs, which is not specifically limited herein. However, for the sake of simplicity, in the following embodiments, only two trains to be coupled are combined into one coupled train as an example.
According to the requirements of each platform in different time periods, a coupling plan and a corresponding coupling area are set, wherein the coupling area is an area for combining the trains to be coupled into the coupling train.
And S02, screening out two trains to be linked according to the linkage plan, and indicating the two trains to be linked to enter the linkage area.
Monitoring all trains running on line, and if two trains to be linked meet the linking plan, firstly sending corresponding control instructions to the trains to be linked to enable the two trains to be linked to enter the linking area.
The coupling area may be a section on the normal driving route or a section outside the normal driving route, and is not specifically limited herein.
If the hitching area is a section on a normal driving route, in the process of monitoring the trains, only the trains entering the hitching area can be screened and judged to obtain two trains to be hitched meeting the hitching plan, and at the moment, the two trains to be hitched do not need to be instructed to enter the hitching area.
Or, the operation plan of each train can be compared with the coupling plan, two trains to be coupled meeting the coupling plan are screened out in advance, and corresponding commands are sent in advance, so that when the two trains to be coupled normally run to the coupling area, the subsequent virtual coupling process is automatically executed.
And step S03, controlling a rear train of the two trains to be linked to approach a front train to reach a preset linking distance.
And after the two trains to be linked enter the linking area, controlling a rear train of the two trains to be linked to approach a front train at a preset relative speed until the distance between the rear train and the front train is less than or equal to a preset linking distance.
Further, the step S03 specifically includes:
step S031, according to the driving mode of said two trains waiting to be linked, set up the corresponding control mode;
and S032, controlling a rear vehicle of the two trains to be linked to approach a front vehicle to reach a preset linking distance.
When controlling the two trains to be linked, a control mode corresponding to a driving mode needs to be set according to the respective driving modes of the two trains to be linked.
Further, the driving modes comprise a train automatic control system CBTC driving grade and a full-automatic unmanned FAM driving grade based on wireless communication.
For the CBCT driving level, since the control of the train is mainly derived from the manual operation of the driver, the driver needs to drive the train to be linked according to the received operation requirement.
And for the driving level of the FAM, the train to be linked directly moves according to the received operation instruction.
Step S04, executing a preset virtual coupling process to combine the two trains to be coupled into a coupling train, and operating in a virtual coupling mode; and the virtual coupling process comprises the step of establishing vehicle-to-vehicle communication between the two trains to be coupled.
And when the distance between the two trains to be linked reaches the linking distance, executing a preset virtual linking process.
The two trains to be linked are combined into one linked train, and the operation is carried out on the track in a virtual linked mode, so that point-to-point vehicle-to-vehicle communication needs to be established between the two trains to be linked. After the virtual hitching is completed, the result needs to be sent to the ground control system, so that the ground control system modifies the operation parameters and the communication mode between the virtual hitching and the trains to be hitched.
According to the embodiment of the invention, the coupling plan and the coupling area are set according to the passenger flow information of each platform, so that the virtual coupling process is executed on the two screened trains to be coupled, the vehicle-to-vehicle communication between the two trains to be coupled is established, and the train operation efficiency is improved.
Based on the above embodiment, further, after the step S04, the method further includes:
s05, performing safety protection on the coupled train according to a preset protection strategy corresponding to the coupled train; wherein the protection policy comprises:
protecting the coupled train by a ground control system;
and the two trains to be linked realize the distance control between the two trains to be linked according to the information interaction of the train-to-train communication.
Because the two trains to be linked, which form the linked train, are not physically linked, when a protection strategy for the linked train in the running process is set, the whole linked train needs to be protected by a ground control system so as to prevent accidents such as collision with other trains. The distance between two trains to be linked needs to be monitored in real time, and specifically, information interaction between the two trains to be linked can be maintained through preset train-to-train communication, so that the two trains to be linked can synchronously run at a preset distance.
The embodiment of the invention realizes the protection between the front and the back of the linked train and between two trains to be linked through the preset protection strategy, thereby ensuring the safety and the reliability of the operation of the linked train.
Based on the above embodiment, further, the step S032 specifically includes:
and stopping the front vehicle in a preset parking area, and controlling the rear vehicle to approach the front vehicle at a preset relative speed by collision movable authorization until the distance between the rear vehicle and the front vehicle is less than or equal to a preset coupling distance.
In the process of controlling the rear vehicle to approach the front vehicle, the front vehicle may be controlled to stop in a designated parking area, then the rear vehicle advances at a preset relative speed and approaches the front vehicle in a collision Movement Authority (MA) manner, and when the distance between the two vehicles reaches a preset coupling distance, the vehicle stops and a subsequent virtual coupling process is performed. And after the virtual coupling process is finished, driving away from the coupling area in a manner of coupling a train.
Of course, in the actual application process, the front vehicle may not be stopped, but the front vehicle may be operated at a relatively low speed, the rear vehicle approaches at a relatively high speed, and the subsequent virtual hitching procedure is started when the interval reaches the preset hitching distance.
According to the embodiment of the invention, the front vehicle stops and the rear vehicle can move in a collision authorization access mode, so that the distance between the rear vehicle and the front vehicle reaches the preset coupling distance, the virtual coupling process is smoother, and the switching efficiency of the operation modes of the train is improved.
Fig. 2 is a flowchart of a method for switching a virtual hitching mode of another train according to an embodiment of the present invention, and as shown in fig. 2, the step S01 specifically includes:
step S011, setting a linkage plan and a linkage area, and an un-editing plan and an un-editing area according to the current passenger flow information of each platform; correspondingly, the method for switching the virtual coupling mode of the train further comprises the following steps:
step S05, if the linked train meets a preset decommissioning plan, controlling the linked train to enter a decommissioning area;
and step S06, executing a preset linkage release process, releasing the virtual linkage mode of the linked train, and dividing the linked train into the two trains to be linked and respectively driving away from the de-editing area.
When the coupling plan and the coupling area are set according to the passenger flow information of each platform, a corresponding decompiling plan and a corresponding decompiling area are also needed to be set, and the virtual coupling mode of the coupled train serving as a large marshalling train is released in the area where only a small marshalling train is needed, so that the coupled train is divided into a plurality of trains to be coupled.
When it is determined that there is a coupled train that satisfies the solution plan, the coupled train may be controlled to enter the solution area first. And then executing a preset coupling releasing process in the de-compiling area, so that the coupling train does not operate in a virtual coupling mode any more, but is disassembled into two trains to be coupled again. And the vehicle-to-vehicle communication of the two disassembled train workshops to be linked is also simultaneously released, and the train workshops respectively drive to the dissociation area in an independent operation mode.
According to the embodiment of the invention, the linked train disconnection process meeting the decompiling calculation is executed through the preset decompiling plan and the decompiling area, so that the passenger flow information of each platform can be better adapted, and the running efficiency of the train is improved.
Fig. 3 is a schematic structural diagram of a switching device for a virtual hitching mode of a train according to an embodiment of the present invention, and as shown in fig. 3, the switching device includes: the system comprises a linkage setting module 10, a linkage screening module 11, a train control module 12 and a linkage execution module 13; wherein the content of the first and second substances,

Specifically, the method comprises the following steps:
according to the requirements of each platform at different time intervals, the coupling setting module 10 sets a coupling plan and a corresponding coupling area, wherein the coupling area is an area for combining trains to be coupled into a coupling train.
The coupling screening module 11 monitors all trains running on line according to the coupling plan and the coupling area obtained by the coupling setting module 10, and if it is determined that two trains to be coupled meet the coupling plan, sends corresponding control instructions to the trains to be coupled first, so that the two trains to be coupled are driven into the coupling area.
The coupling area may be a section on the normal driving route or a section outside the normal driving route, and is not specifically limited herein.
If the hitching area is a section on a normal driving route, the hitching screening module 11 may only screen and judge the train entering the hitching area to obtain two trains to be hitched meeting the hitching plan in the process of monitoring the train, and at this time, it is not necessary to instruct the two trains to be hitched to enter the hitching area.
Or, the hitching screening module 11 may compare the operation plan of each train with the hitching plan, screen two trains to be hitched that satisfy the hitching plan in advance, and send corresponding commands in advance, so that when the two trains to be hitched normally run to the hitching area, the subsequent virtual hitching process is automatically executed.
When it is determined that the two trains to be linked enter the linking area, the linking and screening module 11 instructs the train control module 12 to control a rear train of the two trains to be linked to approach a front train at a preset relative speed until the distance between the rear train and the front train is less than or equal to a preset linking distance.
Further, the train control module 12 is specifically configured to:

Further, the driving modes comprise a train automatic control system CBTC driving grade and a full-automatic unmanned FAM driving grade based on wireless communication.
For the CBCT driving level, since the control of the train is mainly derived from the manual operation of the driver, the driver needs to drive the train to be linked according to the received operation requirement.
And for the driving level of the FAM, the train to be linked directly moves according to the received operation instruction.
When the distance between the two trains to be linked reaches the linking distance, the train control module 12 instructs the linking execution module 13 to execute a preset virtual linking process.
The two trains to be linked are combined into one linked train, and the operation is carried out on the track in a virtual linked mode, so that point-to-point vehicle-to-vehicle communication needs to be established between the two trains to be linked. After the virtual hitching is completed, the result needs to be sent to the ground control system, so that the ground control system modifies the operation parameters and the communication mode between the virtual hitching and the trains to be hitched.

and the two trains to be linked realize the distance control between the two trains to be linked according to the information interaction of the train-to-train communication.
Because the two trains to be linked forming the linked train are not physically linked, when the train protection module sets a protection strategy for the linked train in the running process, the whole linked train is required to be protected by the ground control system so as to prevent accidents such as collision with other trains. The distance between two trains to be linked needs to be monitored in real time, and specifically, information interaction between the two trains to be linked can be maintained through preset train-to-train communication, so that the two trains to be linked can synchronously run at a preset distance.
