when the ID of a target car in the inserted car list is a set insertion identifier and the target car is marked, then the ID of a car that is consecutively arranged after the target car is a set insertion identifier and the consecutively arranged cars are marked;

when the ID of a target car in the insert car list is not a set insert identifier and the target car is not marked, then the consist consecutively arranged after the target car identifies that the same car is not marked.

As shown in fig. 2a, the technical solution provided by the embodiment of the present invention includes:

s210: an inserted car list in the insertion order is determined.

S220: marking the carriage which is inserted into the carriage list and has the same ID as the current train running carriage list; the inserted carriage list comprises a carriage ID which is a carriage identification and a carriage with an inserted identifier.

In the embodiment of the present invention, the car list includes cars with IDs respectively being car identifications and set insertion identifiers, where the set insertion identifiers may be "-", or may also be other insertion identifiers. For example, the list of inserted cars may be illustrated as "A-D-E", where A, D and E are the actual car identifications and "-" is the set insertion identifier, respectively.

In the embodiment of the present invention, the current train operation car list may be specifically obtained from the database, the train operation car list is sequentially traversed, a car with the same ID as that in the current train operation car list is searched from the inserted car list, and the car with the same ID as that in the current train operation car list is marked in the inserted car list.

S230: and taking the formation identifier of the carriage in the current train operation carriage list, which is the same as the inserted carriage list ID, as the formation identifier of the corresponding carriage in the inserted carriage list.

In the embodiment of the invention, after the train with the same ID as that in the current train operation train compartment list is inserted into the train compartment list, the grouping identification of each train in the current train operation train compartment list is respectively assigned to the train with the same ID as that in the inserted train compartment list. For example, the list of inserted cars may be denoted as "A-D-E" and the list of current train running cars may be denoted as "A B C D E", where the cars with the same ID in the list of current train running cars and the list of inserted cars are "A", "D", and "E", respectively. Then the marshalling identifications in which the 'AD E' in the current train operation carriage list are respectively positioned are sequentially assigned to the 'AD E' inserted into the carriage list.

S240: and determining the carriage with the different ID in the current train running carriage list and the last train running carriage list according to the last train running carriage list, and taking the carriage as a newly found carriage.

In the embodiment of the invention, the train running carriage list corresponding to the last running of the train can be obtained from the database, namely the last train running carriage list, the last train running carriage list is compared with the current train running carriage list, and the carriages with different IDs are determined to be newly found carriages. For example, the current train operating car list may be denoted as "a B C D E", the last train operating car list may be denoted as "a D E", and "B" and "C" are newly found cars in the current train operating car list.

S250: and marking the compartment of which the ID corresponding to the specific compartment in the inserted compartment list is a set identifier, and taking the group identifier of the newly found compartment as the group identifier of the compartment of which the corresponding ID in the inserted compartment list is the set identifier.

In the embodiment of the present invention, when there is a newly found car in the current train operation car list, the car inserted into the car list corresponding to the newly found car is: the ID is the car for which the insertion identifier is set. Wherein, newly found carriage and the carriage inserted into the carriage list are corresponding carriages: and inserting the compartment with the same position as the newly found compartment in the compartment list, and taking the grouping identification of the newly found compartment as the grouping identification of the compartment with the same position and the ID set as the insertion identifier in the compartment list. For example, if the list of inserted cars may be denoted as "A-D-E," the list of current train operating cars may be denoted as "A B C D E," and the list of last train operating cars may be denoted as "A D E," then "B" and "C" are the newly found cars in the list of current train operating cars. The grouping identifications of the 'B' and 'C' are respectively used as the grouping identifications of the 'A' and 'D' which are inserted between the 'A' and the 'D' in the carriage list, and the ID is 'minus' carriage.

In the embodiment of the present invention, optionally, a process of specifically marking the car may refer to fig. 2 b. Optionally, when the insertion identifier may be set to be "-", a specific process of marking the car inserted into the car list may be:

the method comprises the following steps: the first car in the current train operating car list in the database is taken out. Wherein the ID of each car in the current train operating car list and the consist number where it is located are known. The consist number of each car in the inserted car list in the insertion instruction is unknown, and the ID of the car in the inserted car list includes a car identification (car actual ID) and a set insertion identifier "-".

Step two: and finding the carriage with the same ID as the carriage taken out from the current train running carriage list in the inserted carriage list, marking the carriage with the same ID as the taken-out carriage in the inserted carriage list if the carriage is found, and recording the position of the current carriage in the inserted carriage list.

Step three: if the car with the same ID as the car extracted in the second step is not found, the first ID of the unmarked car with the "-" is found from the position of the last recorded car, and the marshalling number of the car extracted from the current train running car list is assigned to the unmarked car with the first ID of the inserted car list with the "-", so that the newly found car can be corresponding to the gap inserted in the car list in the insertion command.

Step four: and if the position of the carriage in the inserted carriage list cannot be determined in the second step and the third step, the inserted carriage list in the insertion command does not accord with the set insertion strategy, the insertion command is rejected, and the processing is finished.

Step five: and taking out the next carriage in the current train running carriage list in the database, repeating the step two, the step three and the step four until each carriage in the current train running carriage list in the database is processed, and finishing the processing.

Therefore, the method marks the carriage inserted into the instruction list, and the marking of the carriage can be accurately and quickly realized.

S260: each car is sequentially retrieved from the insertion order list, and the unmarked car is taken as a car gap.

S270: determining that the list of inserted cars meets a set insertion policy if the cars in the list of inserted cars meet the following conditions:

when the ID of a target car in the inserted car list is a set insertion identifier and the target car is marked, the ID of a car that is consecutively arranged after the target car is a set insertion identifier and the consecutively arranged cars are marked;

In the embodiment of the invention, when the target car inserted into the car list is marked and has N consecutive gaps in front of the target car, the group identification of the target car is different from the group identification of the last marked non-gap car of the target car, which indicates that the car to be inserted (the car with the ID set as the insertion identifier) in the inserted car list is inserted between two different groups. For example, if the list of inserted cars is indicated as "a-D-E," D "in the list of inserted cars is marked and the last marked non-gap car that preceded" D "has 2 consecutive gaps, D is a, if the consist identifications of D and a are not the same, indicating that the car to be inserted is inserted between two different consists.

In the embodiment of the present invention, when the ID of the target car inserted in the car list is the set insertion identifier and the target car is marked, the ID of the car arranged consecutively after the target car is the set insertion identifier and the consecutively arranged cars are marked. If the ID of the target compartment is the set insertion identifier and the target compartment is marked, indicating that the target compartment corresponds to the newly discovered compartment; if the ID of the cars consecutively arranged behind the target car is the set insertion identifier and is marked, it indicates that the number of target cars in the inserted car list is the same as the number of newly found cars, i.e., the number of gaps in the inserted car list is the same as the number of newly found cars corresponding to the gaps.

In the embodiment of the present invention, when the ID of the target car inserted into the car list is not the set insertion identifier and the target car is not marked, it indicates that there is no car corresponding to the target car in the current train running car list and also indicates that the target car is the car that disappears in the current train running car list. When the cars in the consist that are consecutively arranged behind the target car and identify the same car are not marked, it indicates that the car that disappears from the current train running car list is a complete consist.

The method flow of specifically inserting whether the car list conforms to the set insertion policy may also refer to fig. 2c, and specifically may be divided into two parts:

the first partial flow may be as follows:

step one, setting hasGap as 0; the values of both preCstNo and currstno are set to 0, and the car inserted in the car list is taken out.

Step two, if the target car is marked and the consist number of the car is recorded into currCstNo, the consist number of the last marked non-gap car of the car is recorded into PRECstNo. If the hasGap flag has been set to 1 (N gap cars ahead of the car) and the values of PRECstNo and CurCstNo are the same, this indicates that a car was inserted within the same consist, and the prescribed policy is not met, exiting, and the process ends. If the values of PRECstNo and CurCstNo are different, the prescribed policy is met and the process continues. The hasGap (here gap) flag is set to 0.

And step three, if the target compartment is not marked, setting the hasGap (gap in the case of the target compartment) mark as 1.

And step four, taking out the next carriage inserted into the carriage list, and performing the same processing from the step 1.

Through the above-described procedure, it is necessary to determine whether the formation numbers of the front and rear cars of each gap are the same. If the two are the same, a new car is inserted inside the consist, and the specified strategy is not met.

The second part of the process may be as follows:

the method comprises the following steps: and taking out each marked carriage inserted into the carriage list.

Step two: if the target car ID is "-" and marked, the following consecutively arranged cars whose IDs are "-" are checked in order from the target car. If there is a car with an ID of "-", but the car is not marked, the check fails, and the set insertion policy is not met.

Step three; if the ID of the target car is not "-" and is marked, the following cars having the same consecutive consist number are checked in sequence from the target car. If there is a marked car, the check fails and the set insertion strategy is not met.

Thus, by performing the check on the marked inserted car list, if there is a car disappearance, the whole cars in the consist disappear. If a gap car is found between two non-gap cars, all intervening gap cars between the two non-gap cars are found. Otherwise, the set insertion strategy is not met.

In the embodiment of the present invention, the method may further include: and when the head carriage in the last train running carriage list is the same as the head carriage in the current train running carriage list and the tail carriage in the last train running carriage list is the same as the tail carriage in the current train running carriage list, judging that the inserted carriage list conforms to the set insertion strategy. That is, when the car inserted into the car list satisfies the three conditions described in S270, and "the head car in the last train operation car list is the same as the head car in the current train operation car list, and the end car in the last train operation car list is the same as the end car in the current train operation car list, it is determined that the inserted car list satisfies the set insertion policy", it is determined that the inserted car list satisfies the set insertion policy.

S280: and updating the train re-running list according to the inserted carriage list to form a new train running carriage list.

Therefore, by marking the cars inserted into the car list and judging whether the inserted car list conforms to the set insertion strategy or not according to the marking result, the strategy conformance check can be quickly, efficiently, stably and reliably carried out, and the method is an important supplement and refinement for the IEC61375-2-3 train topology database protocol.

On the basis of the above embodiment, it may further include updating the train operation marshalling sequence according to the new train operation car list. Each carriage in the new train operation carriage list has a marshalling identifier, a newly inserted carriage in the new train operation carriage list can have an independent marshalling, the marshalling identifier of each carriage in the new train operation carriage list is determined, and the train operation marshalling sequence is updated to form a new train operation marshalling sequence.

In the embodiment of the invention, according to the IEC61375-2-3 protocol standard, a Train marshalling directory (Train direction) and marshalling information (Train information) can be obtained through a Train target computing state machine (Train direction computing state machine) in a Train control management system. The Train direction is a Train formation sequence physically connected in a reference direction, and is used as a first Train formation sequence. The reference direction may be determined according to a set rule, or may also need to be determined. The Train direction can be determined by the Train target computer state machine according to the received message of each marshalling. The Train direction includes attribute information of each consist in a Train, and the attribute information includes a direction of the consist and car sequence information in the consist.

When the direction of each consist in the second train consist sequence and the car sequence information within the consist are integrated into a consist data structure, the consist data structure includes the car sequence information within each consist and each consist, and may also include the direction of the consist. For example, a schematic diagram of integrating the respective consist directions in fig. 3b and 3c in S310 and the car sequence information of the consist into a consist data structure with reference to the opposite direction and the opposite running direction is shown in fig. 3 d.
