Referring to fig. 1, the method includes:

The initial list may be generated by the control device, and the control device may be, for example, the central integrated scheduling system in fig. 2, without limitation.
In the specific execution process, the information of the train is sent to the train control equipment, so that the train control equipment generates an initial list according to the information of each train; an initial list distributed by the train control device is received.
For example, the central integrated dispatching system may obtain information of each train on the track, generate an initial list according to the information of each train, and distribute the initial list to each train, where the information is used to establish a communication connection between each train, and the information is, for example, a train identity, or some corresponding communication protocols, and the like, which is not limited thereto.
S102: the method comprises the steps of obtaining current first operation information of the train and receiving current second operation information of other trains, sequencing the trains according to the first operation information and the second operation information to obtain first sequencing results, and sending the first sequencing results to the other trains respectively.
It is understood that the embodiment of the present invention may be applied to any one of the trains in fig. 2, the operation information of the current train performing S102 may be referred to as first operation information, and the first operation information may be, for example, state information (e.g., start or operation), position information, speed, and other information related to train operation of the current train.
The operation information received by the current train and sent by other trains may be referred to as second operation information, and the second operation information may be, for example, state information (e.g., start or operation) of other trains, location information, and other train operation related information.
In the embodiment of the invention, each train can receive the second operation information through the communication connection directly established between each train, and compared with the related technology in which the information is received through the communication connection established by the trackside equipment, the embodiment of the invention effectively guarantees the timeliness and the precision of the communication.

s301: and judging whether the operation is abnormal or not according to the first sequencing result and second sequencing results sent by other trains received by the self, and triggering and executing a preset control strategy when the operation is abnormal.
In the specific implementation process of the embodiment of the invention, when the running sequence of each train on the track indicated by the first sequencing result is determined to be different from the running sequence of each train on the track indicated by the second sequencing result, the running abnormality can be judged.
In the embodiment of the invention, the actual running scene of the train is combined, because the possible track running abnormity exists and the possible judgment error exists in the technical limitation, each train in the embodiment of the invention maintains a first sequencing result, when the running abnormity is determined, the judgment is carried out by combining the first sequencing result obtained by the train and the received second sequencing results of other trains, the data source is wider, and therefore, the communication control accuracy is improved from another dimension.
For example, if there are train a, train B, train C, and train D currently running on the track, the first sequencing result of train a is: B. c, D, A, and the second sequencing result sent by the train B received by the train a is: B. d, C, A, the second sequencing result sent by the train C received by the train a is: B. d, C, A, the second sequencing result sent by the train D received by the train a is: B. c, D, A, the embodiment of the present invention can determine the train C and the train D as the abnormal vehicles, and then trigger S302 in real time.
S302: and determining a target train with abnormal operation, judging whether the actual operation position of the target train is within the operation range of the target train, and triggering to perform braking control when the actual operation position of the target train is within the operation range.
In the specific implementation process, before judging whether the actual running position of the target train is within the running range of the target train, the current running position of the target train can be determined; and taking the running range within a preset distance before and after the current running position as the running range of the self running range.
In the specific implementation process of the embodiment of the invention, each train determines the target train with abnormal operation, judges whether the actual operation position of the target train is within the operation range of the train, and performs braking control if the actual operation position of the target train is within the operation range.
The target trains with abnormal operation determined by the above example are train C and train D, or the train with abnormal operation may be determined by using other strategies in combination with the actual application scenario, which is not limited.
The running range of each train can be preset, for example, how many meters ahead of the train is defined as the running range, or the running range is calculated by the front train of the train, or the running range can be defined within a certain distance in two possible directions of a turnout under the condition of the turnout, and the train can be flexibly configured according to the actual application scene and the shape of the route.
In this embodiment, if there is a train with abnormal operation, which is a related train in the operation range of the train, the train of the train is emergently braked and the center is alerted, and if there is a train with abnormal operation, which does not affect the operation of the train temporarily, the center is alerted and no special processing is performed, and the train-to-train communication and the sequencing interactive comparison are continued.
Alternatively, it may also be determined whether there is a train with a communication failure in the track; and when the train with the communication fault exists and the actual operation position of the train with the communication fault is within the operation range of the train, triggering to perform braking control.
In this embodiment, when any train loses communication connection with a certain train, connection can be tried again, connection failure information can be sent to the central integrated dispatching system and other trains, and connection still cannot be performed for a certain number of times, it is determined whether the train losing connection is a related train in the train operation range (the train before losing connection, the train losing connection position and the train operation condition in the losing connection process need to be considered in the determination process), if there is a train losing connection and the actual operation position of the train losing connection is within the train operation range, emergency braking can be performed on the train, otherwise, the train can continue to operate and try connection.
In the embodiment of the invention, if the train information exists in the train list, for one train, if other N-1 trains lose communication connection with the train, and after the central comprehensive dispatching system confirms that the train exits from the track line, each train can delete the information of the train in the train list, thereby realizing the stability of communication objects of each train, effectively avoiding the phenomenon of frequent communication switching in the related technology and improving the communication efficiency.
Because the function of vehicle-to-vehicle communication is more concentrated on the vehicle and does not depend on trackside equipment, if a train list in an operation plan is not changed, a train communication object is fixed, and the communication object does not need to be frequently changed according to different target controller areas; the system is in real-time communication with the whole train, so that the state information of the whole train can be dynamically mastered, the flexible planning of the line is facilitated, the speed is adjusted, and the efficiency is improved; the train on the whole line is sequenced in real time, sequencing information is interacted among the trains, sequencing consistency is compared, and train operation safety is improved.
Optionally, in some embodiments, referring to fig. 4, the method may further include:
s401: and when the train operation plan is changed, acquiring the current actual train information after the train operation plan is changed.
S402: and sending the current actual train information to the train control equipment so that the train control equipment updates the initial list according to the current actual train information to obtain a new list.
S403: and receiving a new list distributed by the train control equipment.
Wherein, the new list is obtained by updating the initial list according to the change condition when the train operation plan is changed, and the new list comprises: and information on each train which is actually currently running on the track after the train operation plan is changed.
S404: and according to the new list, directly establishing communication connection with each changed train which actually runs currently.
The new list may be obtained by updating the initial list for the train control device.
For example, the central integrated dispatching system can judge whether the train operation plan is changed; if the change is generated, updating the initial list according to the change condition to obtain a new list; the new list is distributed to each train.
The change condition may be, for example, a newly added train being put into track operation, or a train having a fault and needing to quit track operation.
It can be understood that, when the train operation plan is changed, the situation of each train actually operating on the track may be different from the situation of the train on the track when the initial list is generated, therefore, after the initial list is updated, each train can directly perform real-time communication control between the trains actually operating on the changed track according to the new list, and can realize real-time communication control based on the situation of the train actually operating on the track.
In the specific implementation process of the embodiment of the invention, the communication connection between the trains can be established according to the information in the initial list or the new list.
For example, communication connection between trains can be directly established based on base stations as shown in fig. 2, and since real-time communication control between trains currently running is directly performed, compared with the related art in which communication is established with trains in jurisdiction by target controllers in trackside equipment, the embodiment of the present invention does not rely on trackside equipment, thereby realizing decoupling of trains running on a track from trackside equipment during communication control.
In this embodiment, each train on the track receives an initial list, where the initial list includes: the method comprises the steps that information of each train currently running on a track is obtained, current first running information of the train is obtained, current second running information of other trains is received, the trains are sequenced according to the first running information and the second running information, a first sequencing result is obtained, and the first sequencing result is respectively sent to the other trains; and calculating the movement authorization according to the first sequencing result and second sequencing results sent by other trains received by the mobile authorization device, so that each train running on the track is decoupled from trackside equipment in the communication control process, the timeliness and simplicity of the communication control of each train are improved, and the communication control effect is improved.
