Description

Technical Field

[0001] The present invention relates to the technical field of train marshaling, and in particular to a flexible train marshaling system and method. Background Art

[0002] Flexible marshaling technology refers to connecting multiple unit trains (a train with independent operation capability is called a unit train) to turn the multiple unit trains into a collection that operates as a whole; multiple unit trains that operate through flexible marshaling technology are called train formations; and flexible marshaling technology also includes disassembling a train formation into multiple independently operating unit trains, that is, a reciprocating process.

[0003] This technology allows rail transit operators to dynamically adjust online according to actual passenger and freight flows, thereby matching capacity and volume. Therefore, relevant units have conducted a lot of research in recent years, and some are already undergoing trials or in operation. Flexible marshaling technology is based on the different coupling forms used between unit trains in the train formation. The train formation formed by multiple unit trains is divided into two modes, namely mechanical flexible marshaling and virtual flexible marshaling.

[0004] The difference between virtual flexible marshaling and mechanical flexible marshaling is that there are no mechanical connection devices such as couplers between the unit trains in virtual flexible marshaling. Instead, several flexible marshaling on-board equipment installed on each unit train are coordinated and controlled through wireless communication, so that multiple unit trains can achieve the effect of coordinated operation of the train formation.

[0005] With flexible marshaling technology, the intervals between adjacent unit trains in a train formation are smaller than the intervals between adjacent unit trains when multiple unit trains are operated in traditional fixed block or mobile block. Therefore, the flexible marshaling on-board equipment and the flexible marshaling management unit for operation instructions and management need to design corresponding interfaces and mechanisms to ensure the safe operation of all unit trains in the train formation, and to ensure that no errors will occur during the formation, operation and release of the train formation, which will cause the train formation to be in danger.

[0006] The biggest challenge in solving this problem is that it is necessary to carefully and comprehensively consider the specific circumstances when the operating status of the train formation changes, especially during the formation and disbanding of the train formation. For example, when one or more unit trains are on or about to enter the station approach, it is necessary to consider possible hazardous scenarios and make safety protections. However, the problem that follows is that due to the complexity of the relevant scenarios, excessive safety protection design goes against the original intention of adopting flexible formation technology.

[0007] At present, it is proposed that a solution is not to allow the formation and disbanding of train formations when the unit train is on the station approach or about to enter the station approach, but this solution will greatly limit the line area range of the formation and disbanding of train formations. Furthermore, the line area (such as station tracks, station sections or other non-branching sections) that is more suitable for the formation and disbanding of train formations on the railway line where the train is running is often limited in length. Considering the length of the unit train and the necessary safety interval between adjacent unit trains, the line area for the formation and disbanding of train formations can accommodate a limited number of unit trains. Therefore, how to realize the formation and disbanding of train formations of any number of unit trains within the limited length of the line area has become a problem that needs to be solved urgently.

[0040] The following will be combined with the attached embodiment of the present invention Figure 1 ~Attached Figure 7 , the technical solutions, structural features, objectives achieved and effects in the embodiments of the present invention are described in detail.

[0041] It should be noted that the drawings are in a very simplified form and use non-precise proportions. They are only used to conveniently and clearly assist in explaining the embodiments of the present invention, and are not used to limit the conditions for the implementation of the present invention. Therefore, they have no substantive technical significance. Any structural modification, change in proportional relationship or adjustment of size, without affecting the effects and purposes that can be achieved by the present invention, should still fall within the scope of the technical content disclosed by the present invention.

[0042] It should be noted that, in the present invention, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only the elements explicitly listed, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0043] The present invention provides a flexible train marshaling system, which is used to flexibly marshall a plurality of unit trains, and realize train formation and train formation release of the plurality of unit trains within a line area of ​​limited length.

[0044] like Figure 1 and Figure 6 As shown, the flexible grouping system includes:

[0045] Multiple flexible coupling on-board units (FCOBs) and multiple flexible coupling management units (FCMUs); multiple flexible coupling on-board units and multiple flexible coupling management units, multiple flexible coupling on-board units, and multiple flexible coupling management units all exchange data; if there is only one flexible coupling management unit, data exchange between the flexible coupling management units is not required;

[0046] Each of the flexible marshaling on-board units is respectively arranged on each unit train to obtain the operating status information of the unit train to which it belongs; the flexible marshaling management unit calculates the train marshaling indication information based on all the operating status information; and the flexible marshaling on-board unit controls the operation of the unit train to which it belongs according to the train marshaling indication information.

[0047] Among them, a unit train can be equipped with one flexible marshaling on-board unit or multiple flexible marshaling on-board units; the flexible marshaling on-board unit and the flexible marshaling management unit can be understood as an integrated module, for example, which may include a train control module, a perception system, a sensor or other system interfaces. This type of technology is an existing technology, so it will not be elaborated here.

[0048] The following is a detailed introduction to the flexible marshaling on-board unit, the flexible marshaling management unit, and how to conduct large-scale data interaction.

[0049] (I) Flexible grouping of onboard units

[0050] The flexible marshaling onboard unit is an important device installed on the unit train. As mentioned above, its functions focus on obtaining operation information and executing train marshaling instruction information;

[0051] The running status information includes, but is not limited to, the location of the unit train, the speed of the unit train, the running condition of the unit train, the running mode of the unit train, the integrity of the running status information, the coupling status of adjacent unit trains, the fault information of the unit train, the formation status information, etc. Among them, the formation status information needs to be emphasized. The formation status information is the running status information of the train formation, which includes the number of unit trains, the unique identification of each unit train, the unit train formation status (formed, not formed or other possible states), and other information related to the train formation, which can be used to determine whether the train is running independently or as a group.

[0052] Here, the train formation instruction information is introduced in this section. The train formation instruction information is the information of the train operation instruction calculated by the flexible formation management unit through all the operation status information (preferably, it can also be combined with the external information used for calculation as needed, and the external information includes: the plan or instruction for the formation of the train formation and the state of the signal interlocking system); specifically, the train formation instruction information includes the train formation formation instruction information and the train formation disengagement instruction information. As the name implies, the train formation formation instruction information refers to the instruction for controlling the corresponding single unit train to be coupled with the adjacent unit train; the train formation disengagement instruction information refers to the instruction for controlling the corresponding single unit train to be disengaged from the adjacent unit train; wherein, the train formation formation instruction information and the train formation disengagement instruction information do not only refer to the actions at the moment of coupling and disengagement; they also include the preparatory work before the completion of coupling and disengagement of multiple unit trains, such as controlling the adjacent unit trains to open the interval, controlling the communication connection between multiple unit trains, etc.

[0053] As mentioned above, the flexible marshaling on-board unit has the function of controlling the operation of the train. Therefore, after the flexible marshaling on-board unit receives the corresponding train formation instruction information or the train formation release instruction information, all the flexible marshaling on-board units belonging to the same unit train operate together to control the unit train to which they belong. The coordinated operation of multiple unit trains can realize the formation of the train formation (the execution result of the aforementioned "connection instruction") and the release of the train formation (the execution result of the aforementioned "release instruction").

[0054] (II) Flexible grouping management unit

[0055] The flexible marshaling management unit is a device that generates train formation indication information and train formation disengagement indication information based on operating status information; the installation location is not mentioned above because there is no restriction on the installation location of the flexible marshaling management unit. It can be fixedly installed on a non-train operating path, or on a train operating path, or on a unit train; the focus of the flexible marshaling management unit is to generate train formation indication information and train formation disengagement indication information through operating status information, and the focus is on data interaction rather than installation location, so as long as it is able to interact with data, there is no special requirement for the installation location.

[0056] Specifically, the overall idea of ​​train formation and train formation dissolution is introduced below. The flexible formation management unit receives external information for calculation and forms train formation indication information with train operation status information; specifically, the external information includes: a plan or instruction for train formation formation and information related to non-train entities such as a signal interlocking system status; specifically, the following are two embodiments:

[0057] (1) Train formation

[0058] The plan or instruction for train formation formation is input into the flexible marshaling management unit in advance. Such "plan or instruction for train formation formation" is equivalent to a plan or instruction for triggering the generation of train formation formation instruction information under a specific condition. Such plan and instruction are pre-set by the flexible marshaling management unit. When multiple unit trains meet certain conditions (for example, when the first unit train of a total of N unit trains described later enters the marshaling area), the flexible marshaling management unit will calculate the train formation formation instruction information based on the train operation information, and send the train formation formation instruction information to the corresponding flexible marshaling on-board unit, thereby completing the coupling of multiple unit trains.

[0059] (2) Train formation disbanding

[0060] A plan or instruction for disbanding the train formation is input in advance into the flexible marshaling management unit. Such "plan or instruction for disbanding the train formation" is equivalent to a plan or instruction for triggering the generation of train formation disbanding instruction information under a specific condition. Such plan and instruction are pre-set by the flexible marshaling management unit. When multiple unit trains meet certain conditions (for example, when the first unit train of a total of N unit trains described later enters the disbanding area), the flexible marshaling management unit will calculate the train formation disbanding instruction information based on the train operation information, and send the train formation disbanding instruction information to the corresponding flexible marshaling on-board unit, thereby completing the disbanding of the train formation.

[0061] For example, when multiple unit trains are in a train formation and enter a specific area, all flexible marshaling on-board units obtain the train operation information of each unit train and transmit it to several flexible marshaling management units. Several flexible marshaling management units check whether the train formation operation can be maintained from two levels: on-board and ground interlocking signals. If the train formation maintenance conditions are not met, the train formation will be released.

[0062] In addition, in order to ensure the safety of the train formation and train formation release processes, preferably, in order to ensure the timely responsiveness of the flexible marshaling on-board unit in executing the train formation instruction information from the flexible marshaling management unit, and to prevent the flexible marshaling on-board unit from starting the corresponding operation only after receiving the train formation instruction information, thereby affecting the operation efficiency; the flexible marshaling management unit can pre-set a certain time or a certain buffer distance before the train formation is formed and the train formation is released according to the train operation information, and send the preview information of the train formation instruction information or the preview information of the train formation release instruction information to the flexible marshaling on-board unit in advance.

[0063] (III) Data Interaction

[0064] The focus of the present invention's proposal of "data interaction between the flexible marshaling on-board units and the flexible marshaling management units, between the flexible marshaling on-board units, and between the flexible marshaling management units" is on "data interaction". The connection structure between the flexible marshaling on-board units and the flexible marshaling management units does not limit how the data is transmitted; for example, it can be through direct transmission from the first flexible marshaling on-board unit to the second flexible marshaling on-board unit; it can also be through indirect transmission from the first flexible marshaling on-board unit to the first flexible marshaling management unit to the second flexible marshaling management unit; or when there are multiple flexible marshaling management units, it can be through indirect transmission from the first flexible marshaling on-board unit to the first flexible marshaling management unit to the second flexible marshaling on-board unit; or indirect transmission from the first flexible marshaling on-board unit to the second flexible marshaling on-board unit to the third flexible marshaling on-board unit, etc.

[0065] It can be said that any flexible marshaling on-board unit and any flexible marshaling management unit are capable of receiving all the information of the entire flexible marshaling system, because in the actual operation process, it is not only the operation status information and train marshaling instruction information that are transmitted, but also some other necessary information, so this expression is adopted; the description of the flexible marshaling management unit transmitting information to the flexible marshaling on-board unit mentioned later only represents the transmission direction of the corresponding information, and does not mean that only this type of transmission capability exists.

[0066] The purpose of data interaction is not only to communicate the aforementioned data, but also to ensure the consistency of the entire flexible marshaling system. During the formation and disbanding of train formations, or when the formation remains unchanged, continuous data interaction is carried out to ensure the safety and efficiency of the train route during the formation and disbanding process.

[0067] Take the flexible marshaling on-board unit executing the corresponding train marshaling instruction information as an example. During the process of train formation, train formation operation and train formation release, the flexible marshaling on-board unit cannot rely solely on the train marshaling instruction information from one flexible marshaling management unit. It is also necessary to constantly exchange signals with other flexible marshaling management units to prevent special situations such as a unit train being disconnected or a unit train being in an abnormal state but not being identified by the flexible marshaling management unit. The accuracy of data transmission can even be ensured through secondary transmission of the same train marshaling instruction information.

[0068] Especially for formation status information, if the formation status information is only transmitted through flexible grouping of on-board units to exchange data with each other, there will be certain loopholes due to the lack of an overall verification process. Therefore, this kind of large-scale data interaction can ensure the accuracy of relevant data to the greatest extent.

[0069] The basic structure of the present invention is described above, and several embodiments of the flexible grouping system will be described in detail below.

[0070] (1) Figure 2 As shown, the flexible marshaling system is provided with a flexible marshaling management unit and multiple flexible marshaling on-board units. Each flexible marshaling on-board unit is connected to the flexible marshaling management unit, and the multiple flexible marshaling on-board units communicate with each other. This structure is suitable for simple functional operations because the multiple flexible marshaling on-board units are at the same level.

[0071] (2) Figure 3As shown, the flexible marshaling system is provided with a flexible marshaling management unit and five flexible marshaling onboard units; wherein the flexible marshaling onboard unit 1 and the flexible marshaling onboard unit 2 are respectively connected to the flexible marshaling management unit; the flexible marshaling onboard unit 11 and the flexible marshaling onboard unit 12 are respectively connected to the flexible marshaling onboard unit 1; the flexible marshaling onboard unit 2 is connected to the flexible marshaling onboard unit 21; in this embodiment, the flexible marshaling onboard unit 1 and the flexible marshaling onboard unit 2 are two onboard units with different functions, and the flexible marshaling onboard unit Either the on-board unit 1 or the flexible marshaling on-board unit 2 has a branch of the next level (for example, the flexible marshaling on-board unit 11 is a branch of the next level of the flexible marshaling on-board unit 1). The principle is that by setting different flexible marshaling on-board units and the corresponding next-level branches, the design of several different functions of the flexible marshaling system can be realized; for example, the flexible marshaling on-board unit 1 is used to realize the safety protection function, and the flexible marshaling on-board unit 2 is used to realize the automatic driving function; and so on, more flexible marshaling on-board units can realize communication topology, information system, maintenance system and other functions.

[0072] (3) Figure 4 As shown, the flexible marshaling system shows a flexible marshaling system including an ATP system (Automatic Train Protection) and an ATO system (Automatic Train Operation); in this embodiment, the flexible marshaling on-board unit with this function and the flexible marshaling management unit form a flexible marshaling system as shown in FIG. Figure 4 A hierarchical structure (partial diagram). A flexible marshaling management unit is connected to multiple flexible marshaling onboard units equipped with ATP systems, and multiple flexible marshaling onboard units equipped with ATP systems communicate with each other. Each flexible marshaling onboard unit equipped with ATP system is connected to a flexible marshaling onboard unit equipped with ATO system.

[0073] (4) Figure 5As shown, further, the flexible marshaling management unit, as an operation node for the management of the flexible marshaling system, must consider its performance and capacity in actual operation. Therefore, multiple flexible marshaling management units may be set up at the same time due to performance reasons. Among them, in this embodiment, multiple flexible marshaling management units are adjacently connected in the order of first and second; it should be explained here that it does not exclude the connection between multiple flexible marshaling management units, and the focus is on ensuring data interaction. In this embodiment, generally, multiple unit trains appear in the process of operation, and may be managed by another flexible marshaling management unit due to entering a specific line area or multiple changes in the train formation; therefore, setting up multiple flexible marshaling management units can design different plans and instructions for the operating status of the train formation in different scenarios, thereby increasing the safety of train operation. Among them, for each flexible marshaling management unit, there is a system based on Figure 3 The connection structure of the flexible grouping on-board units is shown.

[0074] The following will take "Operation Status Information" as an example to Figure 3 The data interaction under the embodiment is explained in detail; Figure 3 There are two different levels of branches in the flexible marshaling onboard unit 11, flexible marshaling onboard unit 12, and flexible marshaling onboard unit 21 as the first node; flexible marshaling onboard unit 1 and flexible marshaling onboard unit 2 as the second node; and the flexible marshaling management unit as the main node.

[0075] In this embodiment, the first node sends the running status information to the corresponding second node, and the second node sends the running status information to the master node; in a specific embodiment, the train running status information extracted by some flexible marshaling onboard units is not necessary, so there may be vacant operations of flexible marshaling onboard units, for example, in this embodiment, there may be vacant flexible marshaling onboard units 12. After extracting the formation status information from the running status information, the master node sends it to the second node, and the second node sends it to the first node, but in essence it is still the master node that sends the formation status information to the first node and the second node; the above is an embodiment of the data interaction of "running status information"; in addition, the mode of data interaction of running status information can adopt a sending confirmation mode or a periodic sending mode.

[0076] A flexible marshaling system is described in detail above. A flexible marshaling method for trains is described below. Train formation / train formation disassembly is performed on N unit trains, n=1, 2, 3...N. The method includes:

[0077] Step S1, when a unit train enters the marshaling / unmarshaling area and meets the marshaling point / unmarshaling point inspection conditions, the train formation / train formation unmarshaling is performed on the unit train that meets the conditions; when the formation changes during the formation and unmarshaling process, step S3 is executed until the train formation / train formation unmarshaling of the Nth unit train is completed, and step S4 is entered; when the marshaling point / unmarshaling point inspection conditions are not met at a certain moment, step S2 is entered;

[0078] Among them, how to determine N unit trains to form a train formation / disband a train formation is through the "flexible formation management unit pre-inputs a plan or instruction for forming a train formation" as mentioned above, and inputs information of multiple unit trains to form a train formation / disband a train formation in advance, which is equivalent to determining in advance multiple unit trains that need to form a train formation / disband a train formation. When the first unit train of the total N unit trains enters the formation / disbanding area, the process starts;

[0079] Specifically, when the first unit train enters the marshaling / disbanding area, several flexible marshaling management units generate train marshaling indication information of all flexible marshaling on-board units according to the train operation status information, and transmit it to the corresponding flexible marshaling on-board units. The flexible marshaling on-board units to which the unit train belongs then realize the train formation / train formation disbanding from the first unit train to N unit trains; at the same time, several flexible marshaling management units perform marshaling point / disbanding point inspections. When the marshaling point / disbanding point inspection conditions are met at all times, step S3 is executed when the formation changes during the formation and disbanding process, and the status quo is maintained until the Nth train formation / train formation is formed and disbanded, and step S4 is entered; when the marshaling point / disbanding point inspection conditions are not met at a certain moment, step S2 is entered; for the marshaling / disbanding area, it is the area where the train forms a train formation / train formation is disbanded, and the marshaling point / disbanding point inspection is described in detail later.

[0080] In addition, in step S1, the "when the unit train enters the marshaling / unmarshaling area" is not limited to the first unit train of a total of N unit trains in some specific embodiments. The condition can be set to when the nth train of a total of N unit trains enters the marshaling / unmarshaling area; for example, when the second unit train enters the marshaling / unmarshaling area, the third unit train enters the marshaling / unmarshaling area, etc.; it should be noted here that if this condition setting is to be adopted, it is necessary to plan the length design of the marshaling / unmarshaling area when a total of N unit trains are coupled and uncoupled.

[0081] Step S2, if the train formation is formed at this time, the formation of the train formation is stopped immediately, the formed train formation is disbanded or maintained, and the process goes to step S4; if the train formation is disbanded at this time, the status quo is maintained and the subsequent train is waited to enter the disbanding area, and then the process goes back to step S1;

[0082] Specifically, several flexible marshaling management units send instructions to all flexible marshaling on-board units including stopping train formation / train formation disbanding, wherein such instructions are not sudden interruption type instructions, but rather instructions for safely stopping train formation / train formation disbanding; as described later, if a train formation is formed at this time, the corresponding flexible marshaling on-board unit completes the operation of disbanding the formed train formation or maintaining the status quo; if a train formation is disbanded at this time, the status quo is maintained, while waiting for subsequent trains to enter the disbanding area and continuing to execute the corresponding disbanding operation.

[0083] Step S3, according to the running status of the train formation, complete the locking management and allocation management of the routes in the marshaling area / disassembling area;

[0084] Specifically, this step is to ensure that the unit train can run safely under any circumstances.

[0085] As can be seen from the foregoing, the entire method relies on various operations between the flexible marshaling management unit and the flexible marshaling on-board unit to operate, and will not be elaborated on later.

[0086] In a preferred embodiment, when the connection between any of the flexible marshaling on-board units and any of the flexible marshaling management units is interrupted, both parties should clear the train marshaling indication information, set the formation status information to a dangerous state, and guide all unit trains to the safe side in accordance with safety design principles.

[0087] In step S1, as mentioned above, there is a judgment condition in the flexible marshaling management unit, that is, when the unit train should stop forming the train formation / disengaging the train formation, and a marshaling point / disengaging point inspection is required; (1) The marshaling point inspection is used to prohibit the unit train from forming a train formation when it is within a certain distance from the end of the marshaling area; because if the unit train forms a train formation within the range close to the end, there will be a great risk that the entire process cannot be completed in the marshaling area, which will bring great hidden dangers to the train operation; (2) The same applies to the disengaging point, prohibiting the unit train from disengaging the train formation when it is within a certain distance from the end of the disengaging area, because if the unit train disengages the train formation within the range close to the end, there will be a great risk that the entire process cannot be completed in the disengaging area, which will bring great hidden dangers to the train operation.

[0088] Step S4, end the process.

[0089] The following will introduce the marshaling point / unmarshaling point check in step S1.

[0090] The marshaling point inspection in step S1 includes: Figure 6As shown, d before the end of the grouping area 编组 A marshaling checkpoint is set at a distance (wherein the illustrated distance is only for convenience of explanation and does not represent the actual distance ratio). When the first unit train of a total of N unit trains has not passed the marshaling checkpoint, it runs in a normal state, that is, no running error occurs; when the first unit train of a total of N unit trains passes the marshaling checkpoint, a number of flexible marshaling management units determine whether the N unit trains still need to form a train formation at this time according to the train running status information. If so, it means that the train formation formation is not completed, and the inspection is not satisfied, and the process goes to step S2; if not, it means that the train formation formation is completed, and the inspection is satisfied to maintain the status quo, and the process goes to step S3; for example, when the first unit train has passed the marshaling checkpoint, all unit trains have completed the train formation formation; that is, the flexible marshaling management unit can ensure that before the first unit train passes the marshaling checkpoint, the N unit trains have completed all operations of the train formation formation indication information, and can work with other systems (such as signal interlocking system, safety control system, etc.) to ensure that the protection mechanism of the marshaling area will not be unlocked as the train runs.

[0091] d 编组 The distance should not be less than: (communication timeout judgment time between the flexible marshaling management unit and the flexible marshaling on-board unit + train operation status information update cycle of the flexible marshaling on-board unit) × the maximum allowable speed of the first train in the unit train coupling process + system speed and distance measurement error.

[0092] The unwinding point check in step S2 includes: Figure 7 As shown, d before the end of the unlocking region 解开 The distance between the two trains is used to set the unbundling checkpoint (wherein the illustrated distance is only for convenience of explanation and does not represent the actual distance ratio). When the first unit train of a total of N unit trains has not passed the marshaling checkpoint, it runs in a normal state, that is, no running error occurs. When the first unit train of a total of N unit trains passes the unbundling checkpoint, a number of flexible marshaling management units determine whether the N unit trains still need to unbundle the train formation at this time according to the train running status information. If so, it means that the train formation unbundling is not completed, and the process goes to step S2. If not, it means that the train formation unbundling is completed, then Maintain the status quo and enter step S3. For example, when the first unit train has passed the unbundling checkpoint, all unit trains have completed the unbundling of the train formation; that is, the flexible marshaling management unit can ensure that before the first unit train passes the unbundling checkpoint, N unit trains have completed all operations of the train formation unbundling instruction information, and can work with other systems (such as signal interlocking system, safety control system, etc.) to ensure that the protection mechanism of the unbundling area will be normally unlocked as the train runs, thereby realizing the diversion of some unit trains (because of unbundling), so that the corresponding unit trains can run normally.

[0093] d 解开 The distance should not be less than: the length of the approaching section at the end of the unbundling area + the communication timeout judgment time between the flexible marshaling management unit and the flexible marshaling on-board unit * the maximum allowable speed of the train unbundling process + the system speed and distance measurement error.

[0094] The "simultaneous" in the aforementioned simultaneous "marshaling point / unmarshaling point inspection" means that the corresponding operation should be started when the first unit train of a total of N unit trains enters the marshaling / unmarshaling area, and it cannot be started until the first unit train of a total of N unit trains passes the marshaling / unmarshaling checkpoint. Instead, this inspection is in a state of instant operation, just like the above-mentioned normal state operation; because the last d 编组 With d 解开 The distance is essentially a buffer distance. As a high-speed train, the time difference caused by calculation should be reduced as much as possible.

[0095] Two embodiments will be described below when the first unit train enters the marshaling / unmarshaling area in step S1.

[0096] The first embodiment is when the first unit train enters the marshaling area.

[0097] The step S1 comprises: step T11, when the first unit train enters the marshaling area, the flexible marshaling management unit marks the information of the independent unit trains and the formed unit trains for a total of N unit trains according to the train running status information;

[0098] Among them, the unit trains are marked as independent unit trains and formed unit trains; as the name implies, the independent unit train is a unit train running alone, and the formed unit train refers to a unit train that has a formation relationship with other unit trains;

[0099] The information labeling should also perform a legality check on the train positions of the unit trains to ensure that all unit trains can travel to the marshaling area and that train formations can be formed in the marshaling area.

[0100] Step T12, starting with the 1st unit train, judge the N unit trains one by one. If the n+1th unit train is an independent unit train, a new train formation is formed with the train formation to which the nth unit train belongs; if the n+1th unit is an already formed unit train, the formation to which the already formed unit train belongs and the train formation to which the nth unit train belongs form a new train formation. If the n+1th unit train has been added, the formation of a new train formation is skipped; during the formation of the train formation, a marshaling point inspection is performed simultaneously; when the marshaling point inspection conditions are met at a certain moment, the Nth judgment is completed and step S3 is entered; when the marshaling point inspection conditions are not met at a certain moment, step S2 is directly entered.

[0101] The following is a specific example that will explain in detail how to label information and determine the initial new train formation.

[0102] Assume that there are N unit trains, T1, T2, T3...T N-1 , T N In the process of establishing a new train formation, it is particularly important to determine the first train of the new train formation. The following describes an embodiment when the first unit train information is marked as a unit train and a unit train in the formation:

[0103] (1) T1 information is marked as an independent unit train. When the first unit train enters the marshaling area, the information is marked as an independent unit train. The new train formation formed at this time is [T1], and the subsequent unit trains are coupled according to the above mode;

[0104] (2) T1 information is marked as a unit train that has been formed. If the first unit train enters the marshaling area, the information is marked as a unit train that has been formed, then the flexible marshaling management unit should directly introduce several unit trains in the formed group into the new train formation, and set the first train as the first unit train of multiple unit trains in the new train formation to prevent subsequent confusion.

[0105] After the first train is determined, how to couple is introduced. If the n+1th unit train is an independent unit train, it will directly form a new train formation with the train formation to which the nth unit train belongs. For example, there is already a new train formation [T1, T2, T3], and there is an independent unit train T4. Since it is an independent unit train, it will directly form a new train formation [T1, T2, T3, T4] with [T1, T2, T3];

[0106] If the n+1th unit train is a formed unit train, then the train formation to which the formed unit train belongs and the train formation to which the nth unit train belongs form a new train formation, which is also obvious. In addition, it is also designed that if the n+1th unit train has been added, the process of forming a new train formation is skipped to avoid repeated addition of unit trains in the train formation to which the n+1 unit trains belong. For example, there is a new train formation [T1], and at this time [T2, T3] is an existing train formation. First, check whether T2 is a formed unit train, and then directly form a new train formation [T1, T2, T3]. Then check whether T3 is a formed unit train. Because it already exists, the process of forming a new train formation is skipped.

[0107] Here, on the basis of judging the unit trains in sequence, a step is added to prevent repeated addition to the new train formation to ensure the consistency of the sequence of the judged unit trains, which prevents judgment jumps and ensures that the same unit train will not be added to the new formation twice.

[0108] Preferably, within a certain time or at a certain distance before a train formation is formed for a plurality of unit trains, corresponding advance information is sent to all unit trains to notify relevant personnel or equipment to complete necessary preparations before the train formation is released.

[0109] In addition, during the formation of a train formation, it should be ensured that: (1) the direction of the marshaling area is along the running direction of the unit train; (2) the running status of the flexible marshaling onboard units meets the requirements for the formation of the new train formation; (3) there are no abnormalities in the signal interlocking equipment within the unit train range; (4) there are no obstacles between the coupled unit trains; and (5) there are certain safety restrictions on the distance conditions between adjacent unit trains and the speed of the front unit train when the train formation is running.

[0110] The second embodiment: when the first unit train enters the unlocking area.

[0111] The step S1 comprises: step Q11, when the first unit train enters the unbundling area, the flexible marshaling management unit marks the information of the independent unit trains and the formed unit trains for a total of N unit trains according to the train running status information;

[0112] At this point, there is no doubt that this is a confirmation information to ensure that the information labels of N unit trains are all formed unit trains, and it is helpful to eliminate certain dangerous situations, such as train decoupling; at this time, the first train is the first unit train, and it is more convenient to judge here than when the train enters the marshaling area;

[0113] Step Q12, disentanglement operation is performed on several unit trains among the N unit trains one by one; disentanglement point inspection is performed simultaneously in the process; when the disentanglement point inspection condition is met at a certain moment, the train formation of the Nth unit train is disentangled until it is completed, and when the disentanglement causes the formation to change, step S3 is entered; when the disentanglement point inspection condition is not met at a certain moment, step S2 is directly entered;

[0114] It should be noted here that the uncoupling operation does not only refer to the uncoupling of adjacent unit trains, but also the process of forming a new train formation by multiple unit trains that have not been uncoupled.

[0115] Among them, as mentioned above, it is necessary to judge the N unit trains one by one, because if the unit trains are jumped and released out of sequence at a fixed point, driving risks may occur; therefore, the flexible marshaling management unit judges the N unit trains one by one, and then generates corresponding train formation release information, that is, whether the first unit train and the second unit train are released and whether a new train formation is formed, and whether the nth unit train and the n+1th unit train are released and whether a new train formation is formed.

[0116] The following are specific examples:

[0117] The flexible marshaling management unit marks a total of N unit train information according to the train running status information as: [T1, T2, T3...T N-1 , T N ], the information labels of unit trains are all formed unit trains; for example, this purpose needs to be solved as [T1, T2, T3], and [T4, ...T N-1 , T N ], there is no doubt that the first train is the first unit train T1. At this time, several unit trains in the N unit trains are untied one by one. The first unit train and the second unit train are not untied. At present, there is a formation train [T1, T2, T3...T N-1 , T N ]; The second unit train and the third unit train are not separated, and they are currently a train formation [T1, T2, T3...T N-1 , T N ], the third unit train is separated from the fourth unit train to form two new train formations, [T1, T2, T3], [T4, ...T N-1 , T N ]; if you need to do [T4, ...T N-1 , T N ]If you need to unlock it, follow the same procedure.

[0118] Preferably, within a certain time or at a certain distance before the disengagement operation of the formed unit trains, corresponding advance information is sent to all unit trains to notify relevant personnel or equipment to complete the necessary preparations before the train formation is disengaged.

[0119] In addition, during the process of disentangling a train formation, it should be ensured that: (1) the multiple unit trains entering the disentangling area are an existing train formation that has already been formed; (2) the unit trains can disentangle the train formation in the disentangling area; (3) the direction of the disentangling area is along the running direction of the unit trains; (4) optionally, the corresponding routes are managed or allocated for the new train formation or unit trains after the disentangling.

[0120] It can be clearly concluded from the foregoing that the present invention is highly flexible and can carry out the corresponding coupling and uncoupling processes from the time the nth unit train enters the marshaling / uncoupling area, and can flexibly couple and uncouple trains, for example, 10 coupled unit trains can be uncoupled into 5 groups of 2 coupled train formations; or 5 groups of 2 coupled train formations can be coupled into a train formation of 10 unit trains.

[0121] The above describes how to form and dissolve a train formation for a total of N unit trains. The following describes two embodiments of immediately stopping the formation of a train formation / dissolving a train formation in step S2.

[0122] A first embodiment is to immediately stop the formation of the train formation.

[0123] The step S2 comprises: step T21, immediately stopping the train formation, and subsequently not performing the train formation of the remaining unit trains;

[0124] Step T22, retaining or disbanding the newly formed train formation;

[0125] Because the time is short and the speed is relatively consistent, there is no technical difficulty in retaining or unlocking it.

[0126] The second embodiment immediately stops the train formation from being untied.

[0127] The step S2 includes: step Q21, maintaining the status quo, waiting for the subsequent train to enter the unlocking area, and returning to step S1;

[0128] Step Q22, optionally, setting a timeout period, after which the subsequent train has not entered the unlocking area, then proceeding to step S4;

[0129] Because the time is short and the speed is relatively consistent, there is no technical difficulty in re-connecting.

[0130] In addition, in all steps, several flexible marshaling management units combine flexible marshaling plans or instructions, signal interlocking status, etc. to update the formation status information at all times. Especially in the process of forming a new train formation or disbanding an existing train formation, attention should always be paid to synchronizing the updated operation status information to other unit trains to ensure that each unit train has all the data of the entire flexible marshaling system, thereby increasing the safety of train operation.

[0131] Although the content of the present invention has been described in detail through the above preferred embodiments, it should be appreciated that the above description should not be considered as a limitation of the present invention. After reading the above content, it will be apparent to those skilled in the art that various modifications and substitutions of the present invention will occur. Therefore, the protection scope of the present invention should be limited by the appended claims.
