Detailed Description
In order that those skilled in the art will better understand the present invention, a technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in which it is apparent that the described embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the present invention without making any inventive effort, shall fall within the scope of the present invention.
Fig. 1A is a flowchart of a control method of a train group according to an embodiment of the present invention, where the method may be performed by a control device of a train group, where the control device of the train group may be implemented in hardware and/or software, and the control device of the train group may be configured in an electronic device with corresponding processing capability. As shown in fig. 1B, the method includes:
s110, extracting target train group information at a target train station and front train group information at a front train station point from a train group linked list.
The train group is that a plurality of trains are used as a dispatching main body for dispatching, so that occupation of dispatching resources and route resources in a dispatching process can be effectively reduced, and dispatching efficiency is improved. The train group link list records the vehicle grouping information at each station site through which the train group passes during traveling. The train group information is group structure information inside the train group, such as train identification of trains in the group, arrangement relation of multiple trains, communication mode and the like.
Specifically, the train group passes through a plurality of train stations in the process of running according to a preset route, and the train stations can be used as target train stations, and the last train station of the target train stations driven by the train group is used as a forward train station. During operation of a train group, a change in train group information may occur, for example, in planning of a group linked list, train a may need to exit the group at station 1, train B may need to join the group at station 2, and thus the group information at different stations may be different.
Illustratively, the definition of the linked list content may be:
typedef struct TrainNode
{ TrainSta oTrainSta; train state information/struct train node priority, next; train nodes before and after/}
TrainNode,*TrainLinkList；
typedef struct TrainSta
{ uint32 tranid; train ID/GrpLinkType ePrior; train forward group status (initial status, command issued, adjustment completed)/GrpLinkType eNext; train backward group status (initial status, command issued, adjustment completed)/}
TrainSta。
And S120, if the target train group information and the front train group information are different, generating a train group control task for the target train station according to the target train group information and the front train group information.
The train group control task refers to a group structure changing task of a train group, for example, an exit de-compiling task of a certain train in the train group, a joining and adding service of a certain train, a train replacing task of a certain train to an original train in the group, and the like.
Specifically, the obtained target train group information and the previous train group information may be compared respectively, and whether the group information such as the train identification and the arrangement mode contained in the target train group information and the previous train group information are the same may be obtained respectively. If the group information is different, the group information of the train group at the target train station is changed relative to the group information of the last train station, namely the train group performs group structure change at the target train station, and the train group is required to perform train group control tasks at the target train station. Thus, when it is determined that there is a difference between the train group information and the preceding train group information, a specific train control task is generated according to the specific difference.
Optionally, the generating a train group control task for the target train station according to the target train group information and the front train group information includes:
comparing the train information in the target train group information and the front train group information; if the fact that the train to be compiled exists in the target train group information is determined according to the comparison result, generating a train group control task at least comprising a train compiling task at the target train station; and if the train to be decomplexed exists in the target train group information according to the comparison result, generating a train group control task at least comprising the decomplexed task at the target train station.
Specifically, the train identifications in the target train group and the train identifications in the front train group are compared, and if the train identifications which do not exist in the front train group appear in the target train group, the train group is indicated to be at least additionally encoded with a new train to be encoded, so that the train group control task at least also comprises the encoding task corresponding to the train to be encoded. If the target train group lacks the existing vehicle identification in the previous train group, it is indicated that at least one train to be decompressed exits the train group at the target station, and therefore the train group control task at least also comprises the corresponding decompressing task to be decompressed. When the control task of the train group needs to be described, the control task of the train group can simultaneously comprise different coding or decoding services, and the control task of more complex replacement and the like can be realized by combining the coding and decoding services.
Fig. 1B is a schematic diagram illustrating a group plan establishment according to an embodiment of the present invention.
Trains T01 and T02 start consist at "station 1", then run to "station 2", T03 joins consist, run sequentially to "station 3", "station 4", and exit consist at station 4, T02. Creating a train group linked list, generating a 1 st node, { station 1, train linked list [ T01/T02] }, adding the linked list, and sequentially adding a 2 nd node { station 2, train linked list [ T01/T02/T03] }, a 3 rd node { station 3, train linked list [ T01/T02/T03] }, and a 4 th node { station 4, train linked list [ T01/T03] } according to the same principle. And the subsequent ground planning center issues a plan according to group information at different train station points, and generates a train group control task of adding T03 into a train chain after reaching station 2, generates no control task after reaching station 3, and generates a train group control task of deleting T02 from the train chain after reaching station 4.
And S130, adjusting the target train group relation at the target train station according to the train group control task.
Specifically, since the train group is a plurality of trains serving as a main body to be scheduled, certain requirements are required for the group relationship inside the group, such as the front-back relationship, the safety distance, the communication relationship and the like among different trains inside the train group. After the need of adding or removing the codes is determined, the group relation is adaptively adjusted so as to ensure that the train group still normally operates according to the train group linked list planning after the train group control task is executed.
According to the train group control task scheduling method and device, the train group information is planned in the form of the linked list, whether the train group control task needs to be generated and executed is determined based on the train group information at different train stations in the linked list content, so that orderly planning when a plurality of trains are operated as a scheduling main body is achieved, and the scheduling efficiency of the trains is improved.
Optionally, the adjusting the target train group relationship at the target train station according to the train group control task includes:
determining a new communication relationship between a train to be adjusted and the train to be adjusted at a target train station according to the train group control task; the new communication relationship comprises a new forward communication relationship and/or a new backward communication relationship; and sending a group relation adjustment instruction to the train to be adjusted according to the new communication relation, wherein the group relation adjustment instruction is used for indicating the train to be adjusted to carry out communication relation adjustment.
The train to be regulated is a train whose communication relationship needs to be regulated in the process of the group control task, and can be a train newly joining or exiting from a group, or a train whose communication relationship needs to be regulated in an associated way due to the regulation of other trains. The forward communication relation and the backward communication relation are respectively the identification of the forward communication train and the backward communication train of the train to be adjusted.
Specifically, when a plurality of trains operate as a train group, communication relations between different trains in the same group need to be established so as to ensure the consistency of behaviors in the operation process. After determining that there is a change in train group information to generate a train group control task, it is necessary to adaptively adjust the communication relationship between train groups. And determining the train to be regulated and the communication direction which need to be regulated, thereby generating a new communication relation. After the new communication relation is determined, issuing a group relation adjustment instruction and security certificate (MA) information to the trains to be adjusted in each group, so that the trains to be adjusted can determine communication objects of the new communication relation according to the group relation adjustment instruction, and establish the new communication relation through authentication of the communication objects based on the MA information.
Optionally, the method further comprises: under the condition that any train to be added is newly added into the target train group information, the group state of the train to be added in the target train group information is an initial state; the group status includes a forward group status and/or a backward group status; after a group relation adjustment instruction is sent to the train to be coded, the group state of the train to be coded is a command issued state; and after the communication relation is successfully regulated by adopting the group relation regulating instruction of the train to be compiled, the group state of the train is the regulated state.
Specifically, for each train in the train group, there are forward and backward group states for implementing ordered control of the train group in the process of executing the train group control task. For the train to be added which is not added into the group, both are in an initial state, for the train which has already executed the group relation adjustment instruction, the group state is the completed adjustment state, and for the train which has received the group relation adjustment instruction but has not completed the instruction, the corresponding state is the order issued state.
Illustratively, the train T01 is added to the linked list in the train group linked list, and both the forward group status and the backward group status of the train T01 are set to be "initial status". Adding the train T02 into a linked list, setting the backward direction of the T01 as T02, setting the forward direction of the T02 as T01, and updating the backward direction group state of the T01 and the forward direction group state of the T02 as 'order issued'. And the trains T01 and T02 respectively complete communication establishment with another vehicle to be regulated according to the received group relation regulation instruction of the ground control center and MA information of the other train, feed back successful grouping connection information, update the backward group state of the ground control center to be 'completed regulation', and update the forward group state of the ground control center to be 'completed regulation'.
In the method, the generation and the issuing of the group linked list can be performed by the same main body, or the generation and the issuing of the linked list can be performed by a cloud server, the ground planning center determines whether to generate the train group control task, and the ground control center performs the train group control task and adjusts the group relation of the train group. The ground planning center and the ground control center can be deployed at each train station independently or can be shared by a plurality of train stations, the specific execution mode is determined according to the requirement, and the invention is not excessively limited.
Fig. 2A is a flowchart of a control method for a train group according to another embodiment of the present invention, where the embodiment is optimized and improved based on the foregoing embodiment. As shown in fig. 2A, the method includes:
s210, extracting target train group information at a target train station and front train group information at a front train station from a train group linked list;
s220, if the target train group information and the front train group information are different, generating a train group control task for the target train station according to the target train group information and the front train group information;
and S230, adjusting the relation of the target train group at the target train station according to the train group control task.
S240, updating the train group linked list according to at least one of the working state of the train, the working state of the train station and the train group change information.
Specifically, when the train group runs on the predetermined route, various unexpected situations may be encountered, for example, a certain train in the train group needs to be removed from the train group due to sudden abnormality, a certain train station on the predetermined route needs to bypass due to failure, different train groups need to be temporarily combined into one group at the target station, and the like. Therefore, the working state of the train station and the train group change information need to be monitored, and when the problem that occurs is determined to influence the normal implementation of the planning of the train group linked list, the train group linked list is updated when corresponding to ensure that the updated train group linked list can be normally executed.
Optionally, updating the train group linked list according to the working state of the train and/or the working state of the train station includes:
if any train is abnormal at any train station, acquiring at least one other train station positioned behind the train station, and rejecting the train from other train group information of other train stations; if any train station is abnormal, determining a replacement station of the train station and replacement train group information of the replacement station, and replacing the abnormal train group information of the train station in the train group linked list by adopting the replacement train group information of the replacement station.
Specifically, in order to avoid the problem that a control instruction related to a train cannot be normally processed at a subsequent train station when an abnormality occurs in a certain train and the train cannot continue to run as a part of a train group, the invention eliminates the train from other train group information of other subsequent train stations when the abnormality occurs in the train.
Fig. 2B is a schematic diagram illustrating temporary adjustment of train group plans according to another embodiment of the invention. When the train arrives at the station 2 in the normal running process, the train T01 suddenly breaks down, needs to be maintained and exits from operation, and the train T04 is newly added from the station 3 to be added into the marshalling operation, and at the moment, the train group linked list information in the planned stations 3 and 4 is adjusted. The 3 rd station is adjusted to be changed into { station 3 and train linked list [ T01/T02/T03] }, and the 4 th station is changed into { station 4 and train linked list [ T03/T04] } from { station 4 and train linked list [ T01/T03] }.
FIG. 2C is a schematic diagram of a temporary adjustment stop plan according to another embodiment of the present invention:
when the train group normally operates and reaches the station 2, the station 3 burst line closure needs to bypass the station 5 and the station 6, at the moment, the station information of the original planning node 3 is modified, and after a new node is added to group trains to operate to the station 2, the station 3 is closed, at the moment, the 3 rd node is regulated to be modified from { station 3, a train linked list [ T01/T02/T03] } to { station 5, a train linked list [ T01/T02/T03] }, and the node 5{ station 6 and the train linked list [ T01/T02/T03] } are directly added to the original 3 rd node and the 4 th node.
Optionally, updating the train group linked list according to the train group change information includes:
if the train group changing information is group disassembling information of any train station, the train group information of the train station is disassembled into at least two new train group information; and if the train group changing information is the group combination information of any train station, combining at least two train group information of the train station into new train group information.
Specifically, the scheduling resources in a certain time in the station are fixed, and in general, the inbound or outbound between different scheduling subjects are staggered in the planning, and the different scheduling subjects can occupy the inbound and outbound resources in a peak-shifting manner. However, when one scheduling entity deviates from the planned operation and delays the incoming/outgoing or other actions needing to occupy the scheduling resources outside the plan, the two different scheduling entities may need to rob the same scheduling resource in a certain time. According to the invention, whether the train group needs to be changed is determined according to the working state of the station, different two train group information can be temporarily combined into one new train group information, and the conflict between the dispatching main body and the dispatching resource is eliminated through the combination of the two dispatching main bodies; when the dispatching resources are rich, the train group information can be split into at least two new train group information, so that the dispatching efficiency is further improved.
Fig. 2D is a schematic diagram illustrating an overline adjustment plan according to another embodiment of the present invention.
The original programming runs independently for group 1[ T01/T02/T03] and group 2[ T04/T05], where group 2[ T04/T05] enters L1 from L2 at site 3. Group 1[ T01/T02/T03] requires rescaling the plan at a later point, and continues to run after "site 3" group 1[ T01/T02/T03] is grouped together with group 2[ T04/T05] from L2. And modifying the linked list of the original group, and at the moment, regulating the 3 rd node to merge 2 train chains, wherein { site 3 and train linked list [ T01/T02/T03] } are modified into { site 3 and train linked list [ T01/T02/T03/T04/T05] }.
The embodiment of the invention determines the burst problem by detecting the working state of the train, the working state of the train station and the train group change information, and updates the train group information according to the burst problem, so that the train group linked list to be executed can be updated according to the actual situation, and the effectiveness of the train group linked list and the normal execution can be ensured.
