Description

Train coupling method and device and train decompiling method

Technical Field

The invention relates to the technical field of rail transit, in particular to a train coupling method and device and a train decompiling method.

Background

In the prior art, most of trains in a conventional urban rail transit line are fixed marshalling trains, the marshalling structure of each pair of trains is fixed, the vehicles and the sequence of each pair of trains are fixed, and when the number of train compartments required by the trains in a peak period is met, the passenger carrying capacity of each train is increased by increasing the running interval of two workshops in a low peak period, so that the traveling efficiency and the traveling experience of passengers are reduced; or a marshalling mode of manually carrying out linkage and un-marshalling operation on the vehicle sections is adopted, so that the labor cost is increased, and the problem of passenger flow tide distribution cannot be solved more efficiently. In addition, when a single train has a fault and cannot be degraded to return to the garage, another train usually adopts a manual linkage mode, and a rear train pushes a front train to slowly move to a nearby platform to complete passenger clearing, and then a tail train pushes the front train to slowly return to the garage, so that normal passenger carrying operation of the route is seriously influenced. Because of the need to work in a specific place, the manual linkage and de-compilation mode is also restricted in space.

The defect of the prior art scheme is that when the number of train carriages required by a train in a peak period is met, the passenger capacity of each train is increased by increasing the running interval between two trains mostly in a low-peak period, so that the traveling efficiency and the traveling experience of passengers are reduced. Although the marshalling mode of manually performing the linked and un-marshalling operation on the vehicle sections can change the problems encountered by fixed marshalling to a certain extent, the problem of passenger flow tidal distribution cannot be solved more efficiently: firstly, the labor cost is wasted; secondly, when the passenger flow tide is very large or the passenger flow distribution of the distribution line is not uniform and obvious, the problem is solved with low efficiency; and when a train fault occurs, the normal passenger carrying operation of the line can be seriously influenced.

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.

A train linkage method and apparatus and a train decompiling method according to an embodiment of the present invention are described below with reference to fig. 1 to 13.

It should be noted that, during the process of linking and de-editing a train, the train may be divided into a front train and a rear train according to the position of the train, and the first terminal described in the following detailed description may be a VOBC (Vehicle On-board Controller) of the rear train, and correspondingly, the second terminal is a VOBC of the front train.

Of course, the order may be switched, and the first terminal may be the VOBC of the preceding vehicle, and correspondingly, the second terminal may be the VOBC of the following vehicle.

As shown in fig. 1, an embodiment of the present invention provides a Train coupling method, where an execution subject of the Train coupling method may be an ATS (Automatic Train Supervision) system, and the Train coupling method includes the following steps 100 to 400.

In step 110, based on a preset virtual grouping list, the hitching preparation information is sent to the first terminal, and the hitching preparation information has characteristic information corresponding to the first terminal and the second terminal.

It can be understood that the ATS system may compile a train list for virtual marshalling to be linked according to the peak time of train passenger flow, that is, a virtual marshalling list, and when the time reaches the linking time in the virtual marshalling list, automatically trigger event command issue, or manually confirm the command issue, and send linking preparation information to the first terminal in the virtual marshalling list, where the linking time needs to be linked.

The preset virtual grouping list may include: the virtual coupling time, the train group number of the virtual formation, the train VID within the virtual formation, the train coupling end information, and the coupled train IP information.

The information of the prepared linkage contains the characteristic information corresponding to the first terminal and the second terminal, and the first terminal and the second terminal can be matched, so that the first terminal and the second terminal can determine that the other terminal is the object of the linkage operation through the information of the prepared linkage.

And step 120, receiving the first terminal state information generated based on the hitching preparation information and sent by the first terminal.

It can be understood that the first terminal state information is generated when the first terminal determines that the hitching condition is satisfied based on the hitching preparation information, sends a virtual hitching request to the second terminal, determines that the vehicle control information generated based on the virtual hitching request and sent by the second terminal is received, and determines that the hitching state is satisfied.

The hitching preparation information may include: the train group number of the virtual formation, the train VID within the virtual formation, the train coupling end information, and the coupled train IP information.

The first terminal state information may include: the train group number of the virtual formation, the train VID within the virtual formation, the train coupling end information, the coupled train IP information, and the inter-coupled train wireless communication state information.

Step 130, receiving second terminal state information sent by the second terminal, where the second terminal state information is generated by the second terminal based on the received virtual attach request, and the virtual attach request is sent by the first terminal to the second terminal based on the attach preparation information.

It can be understood that the second terminal establishes a communication connection with the first terminal when receiving the communication request sent by the first terminal, receives the virtual attach request sent by the first terminal, determines whether the attach state is satisfied when determining that the virtual attach request passes verification, and sends the second terminal state information to the ATS system when determining that the attach state is satisfied.

Here, the ATS system receives second terminal status information sent by the second terminal, where the second terminal status information includes: the train group number of the virtual formation, the train VID within the virtual formation, the train coupling end information, the coupled train IP information, and the inter-coupled train wireless communication state information.

And step 140, sending the connection confirmation information to the first terminal and the second terminal based on the first terminal state information and the second terminal state information.

It can be understood that, the ATS system may confirm that the first terminal and the second terminal both enter the hitching state according to receiving the first terminal state information sent by the first terminal and the second terminal state information sent by the second terminal, and then send the hitching confirmation information to the first terminal and the second terminal, which is a second sending instruction relative to the first hitching preparation information sent to the first terminal, and this is just to ensure information confirmation by way of second confirmation, which can ensure the safety of information transmission, and can ensure the safety and stability of the hitching process, and reduce the risk of occurrence of accidents.

It should be noted that, in the embodiment of the present invention, the ATS system sends the hitching preparation information to the corresponding hitching train when the hitching timing is satisfied by building a virtual marshalling list, so that the excessive IP information of other trains locally stored in the VOBC of the train can be avoided, the hitching of the train and other trains can be more free, the limitation of the hitching operation of the train is reduced, and the virtual marshalling can be more flexible.

As shown in fig. 1, in some embodiments, step 140, sending the hitching confirmation information to the first terminal and the second terminal, and then further includes: and informing the area controllers where the first terminal and the second terminal are located not to calculate the mobile authorization of the first terminal and the second terminal, and not to send the mobile authorization to the first terminal and the second terminal.

It is understood that ZC (Zone Controller) is a ground core control device in rail transit, and is a hub for ground-vehicle information interaction. The system is mainly responsible for calculating and generating Mobile Authorization (MA) for the communication trains in the control range according to the position information reported by the communication trains and the track occupation/idle information provided by the access and trackside equipment arranged in an interlocking manner, ensures the safe operation of the communication trains in the control area, and has the capability of train management under various train control levels and driving modes.

It is worth mentioning that the ZC can calculate the movement authorization for the trains based on the route handling condition of the interlocking equipment, and the movement authorization of the two trains is ensured not to overlap each other through mutual exclusion of the enemy relation of the routes, so that the condition that the two trains collide with each other in the head-on direction is prevented. In other words, if the movement authorization is calculated and sent to two adjacent trains, the two trains can only be mutually exclusive and cannot approach each other, and once the two trains approach each other, the two trains are locked, so that the traveling areas of the two trains cannot be overlapped, and therefore, the collision linkage operation cannot be performed.

After the first terminal and the second terminal are determined to enter the linked state, the area controllers where the first terminal and the second terminal are located are notified not to calculate the mobile authorization for the first terminal and the second terminal, and the mobile authorization is not sent to the first terminal and the second terminal. At the moment, the train where the first terminal is located and the train where the second terminal is located can not be mutually exclusive, and the first terminal and the second terminal cannot be locked due to proximity, so that collision linkage operation can be carried out.

In a specific embodiment, the train coupling method provided by the embodiment of the invention includes the following steps: the ATS system sends linkage preparation information to a VOBC of a rear vehicle based on a preset virtual marshalling list; after receiving the linking preparation information, the VOBC of the rear vehicle sends a communication request to the VOBC of the front vehicle based on the received linking preparation information; after receiving a communication request sent by the VOBC of the rear vehicle, the VOBC of the front vehicle establishes communication connection with the VOBC of the rear vehicle; determining that the VOBC of the rear vehicle meets the linkage condition, and sending a virtual linkage request to the VOBC of the front vehicle; the VOBC of the front vehicle receives a virtual coupling request sent by the VOBC of the rear vehicle, confirms that the virtual coupling request passes verification, confirms that the coupling state is met, sends vehicle control information to the VOBC of the rear vehicle, and sends the VOBC state information of the front vehicle to the train automatic monitoring system; the VOBC of the rear vehicle determines that vehicle control information generated based on the virtual coupling request and sent by the VOBC of the front vehicle is received, determines that the coupling state is met, and sends the VOBC state information of the rear vehicle to the train automatic monitoring system; the ATS system receives VOBC state information of a front vehicle sent by VOBC of the front vehicle, receives VOBC state information of a rear vehicle sent by VOBC of the rear vehicle, sends linkage confirmation information to VOBC of the rear vehicle and VOBC of the front vehicle based on VOBC state information of the rear vehicle and VOBC state information of the front vehicle, informs a region controller where a first terminal and a second terminal are located not to calculate mobile authorization of the first terminal and the second terminal, and does not send the mobile authorization to the first terminal and the second terminal; and the VOBC of the rear car carries out linkage operation according to the car control information based on the received linkage confirmation information.
