[0045] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0046] In addition, the term "and / or" in this article is only a description of the association relationship between the associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0047] In the present disclosure, firstly, the train automatic monitoring system obtains information data of all trains on the entire line and stores it in a key-value pair manner to generate a key-value pair data set, wherein the train unit number is used as the key and the platform information data of the corresponding train is planned to pass as the value; secondly, according to the train type and manually set information or plan diagram, the marshaling-related status of the platform that the corresponding train is planned to pass through in the key-value pair data set is updated; the updated key-value pair data set is converted into a preview information list, and the preview information list is dynamically updated according to the real-time operation status of the train; finally, based on the dynamically updated preview information list, in different marshaling and unmarshaling scenarios, the corresponding marshaling information status is sent to the platform passenger information system through the marshaling information interface; the platform passenger information system displays the operation information of the flexible marshaling train based on the received and summarized marshaling information status. In this way, the problem that the traditional platform passenger information system does not have the advance information for announcing flexible train operations can be solved, so that in a complex and changeable train operation environment, especially in scenarios where train marshaling and disassembly are flexible and changeable, effective management and real-time updating of train marshaling information can be achieved, and accurate and timely marshaling information status can be provided to the platform passenger information system, which not only improves the passengers' riding experience, but also improves the service quality and operational efficiency of rail transit.

[0048] In conjunction with the accompanying drawings, a method for calculating and displaying train operation information supporting flexible formation provided by an embodiment of the present disclosure is described in detail below through specific embodiments.

[0049] Figure 1 A flow chart of a method for calculating and displaying train operation information supporting flexible marshaling provided by an embodiment of the present disclosure is shown, such as Figure 1 As shown, a method 100 for calculating and displaying train operation information supporting flexible marshaling may include the following steps:

[0050] S110, obtaining information data of all trains on the entire line, and storing them in a key-value pair format to generate a key-value pair data set, wherein the train set number is used as the key and the platform information data of the corresponding train is used as the value.

[0051] Exemplarily, after obtaining the raw data, data parsing operations are performed, and data cleaning is performed during the parsing process to eliminate erroneous, duplicate or inconsistent data, for example: checking data integrity to ensure that each train has complete train number and planned route information; removing duplicate data to avoid the same train number being recorded multiple times; formatting data to ensure that all platform information follows the same format.

[0052] The cleaned data is organized into the form of key-value pairs, where the key is the train set number and the value is the information data of all platforms that the train is scheduled to pass through. The defined single platform information includes but is not limited to: the estimated arrival time of the train at the platform, the planned departure time, and the status related to the flexible marshaling status, etc.

[0053] S120, updating the marshaling-related status of the platform that the corresponding train is scheduled to pass through in the key-value pair data set according to the train type and the manually set information or the plan diagram.

[0054] In some embodiments, if the train is a head train, the marshaling-related status of the corresponding platform that the train passes through is updated according to the manually set information;

[0055] If the train is a planned train, the marshaling-related status of the corresponding platform that the train passes through will be updated according to the planned diagram.

[0056] For example, the lead train refers to a train that is the first or independently operated train in actual operation, whose operation is not affected by other trains and has independent operation plans and marshaling requirements.

[0057] The update process generally includes the following steps:

[0058] First, obtain relevant setting information of the first wagon through the station's control system or manual operation interface, including but not limited to train number, marshaling method (such as the number and type of carriages, etc.), stop platform, etc.

[0059] Secondly, based on the obtained setting information, the marshaling-related status of the platform through which the corresponding train passes is automatically or manually updated. This includes reflecting the train's marshaling status in real time on the control system or display screen at the station so that station staff and passengers can accurately understand the train information.

[0060] Finally, after the update is completed, the system automatically verifies to ensure the accuracy and consistency of the information. At the same time, it provides necessary feedback mechanisms, such as sound and light signals or information prompts, to inform the operator of the update status.

[0061] Exemplarily, a planned train refers to a train that runs according to a pre-determined operation plan (such as a train timetable), and its operation and marshaling status are usually arranged based on a plan diagram.

[0062] The update process generally includes the following steps:

[0063] First, obtain the latest train operation plan through the central control room or relevant management system of the railway system, including detailed information such as train number, departure time, stop stations, and marshaling method.

[0064] Secondly, according to the plan, the marshaling status of the corresponding platform that the train passes through is automatically updated, which includes adjusting the station's display system to reflect the train's real-time marshaling and arrival information.

[0065] Finally, during operation, if there are train delays, cancellations, or changes in train formation, the system must be able to adjust the train formation status in real time based on the latest schedule information.

[0066] S130, converting the updated key-value pair data set into a forecast information list, and dynamically updating the forecast information list according to the real-time running status of the train.

[0067] In some embodiments, a preview information key-value pair list is created based on the updated key-value pair data set, wherein the platform number is used as the key and the train information data passing through the corresponding platform in sequence is used as the value, and only the train information data of less than 3 trains can be stored in the value, and the train information in the value is dynamically updated according to the real-time operation status of the train.

[0068] Exemplarily, an empty list of advance information key-value pairs is created, where the key is the platform number and the value is a list of train information data that passes through the platform in sequence. The train information data should include key information such as the train set number, estimated arrival time and estimated departure time.

[0069] Traverse the updated key-value pair data set. For each train, use each platform number that it plans to pass through as a key and look up the corresponding value in the forecast information key-value pair list.

[0070] If the platform number already exists in the list, check whether the current train information already exists in the train information data list of the platform (to avoid duplicate addition). If not, and the number of train information data in the list is less than 3, add the train information to the list; if the number of train information data in the list has reached 3, but the new train information has a higher priority (for example, a train closer to the current time or belonging to a specific category), then a piece of information in the list can be replaced according to preset rules.

[0071] The train information data list for each platform is sorted according to the estimated arrival time to ensure that the train information in the list is arranged in chronological order.

[0072] Through the central control room of the railway system, the train positioning system or related sensors, the train's operating status information, including current position, speed, estimated arrival time and estimated departure time, can be obtained in real time.

[0073] The train operation status information obtained in real time is matched with the train information in the list of advance information key-value pairs: if the match is successful, the train status (such as expected arrival time and expected departure time) in the train information data list of the corresponding platform is updated according to the real-time data; if the train is cancelled or the operation plan is changed for some reason, the corresponding train information is deleted or replaced from the list.

[0074] S140, based on the dynamically updated advance information list, in different marshaling and unmarshaling scenarios, sending corresponding marshaling information status to the platform passenger information system through the marshaling information interface.

[0075] In some embodiments, in a scenario where mechanical marshaling or static virtual marshaling is performed on the platform, the corresponding marshaling information status is sent to the platform passenger information system through the marshaling information interface;

[0076] In the scenario where the train runs to the platform in a virtual marshaling or mechanical marshaling state, the corresponding marshaling information state is sent to the platform passenger information system through the marshaling information interface;

[0077] In the scenario of mechanical unmarshaling or static virtual unmarshaling on the platform, the corresponding marshaling information status is sent to the platform passenger information system through the marshaling information interface;

[0078] In the scenario where a single vehicle arrives at the platform, the corresponding marshaling information status is sent to the platform passenger information system through the marshaling information interface.

[0079] In some embodiments, when mechanical marshaling or static virtual marshaling is performed on the platform, the marshaling train needs to report the marshaling information status to the platform passenger information system before entering the marshaling platform until the train completes marshaling;

[0080] After the train is marshaled, only the leading car is retained to report the marshaling information status to the platform passenger information system until the leading car leaves the marshaling platform.

[0081] In some embodiments, when running to the platform in a virtual marshaling or mechanical marshaling state, only the marshaling lead car is retained to report the marshaling information status to the platform passenger information system until the marshaling lead car leaves the marshaling platform.

[0082] In some embodiments, when mechanical unmarshaling or static virtual unmarshaling is performed on the platform, only the leading train of the marshaling is retained to report the marshaling information status to the platform passenger information system until the unmarshaling of the marshaling train is completed;

[0083] After the marshaling train is disassembled, only the leading car of the marshaling train is retained to report the marshaling information status to the platform passenger information system until the leading car of the marshaling train leaves the marshaling platform;

[0084] After the leading car of the marshaling leaves the marshaling platform, only the following car of the marshaling is retained to report the marshaling information status to the platform passenger information system until the following car of the marshaling leaves the marshaling platform.

[0085] In some embodiments, when running on the platform in a single-car state, the unit train reports the marshaling information status to the platform passenger information system until the marshaling lead car leaves the marshaling platform.

[0086] For example, in the scenario of mechanical marshaling or static virtual marshaling on the platform, before the leading car of the marshaling enters the marshaling platform, it needs to report the marshaling information status to the platform passenger information system as follows:

[0087] Marshalling status: indicates whether it is currently "virtual marshaling" or "mechanical marshaling";

[0088] Marshalling process status: set to "pending marshalling";

[0089] Position status of marshaling train: indicated as “leading train”;

[0090] Marshalling another car group number: fill in the "corresponding following car group number";

[0091] Destination of another vehicle: Fill in "Destination of the corresponding following vehicle";

[0092] Until the train is completed.

[0093] Accordingly, before the marshaling follower car enters the marshaling platform, it needs to report the marshaling information status to the platform passenger information system as follows:

[0094] Marshalling status: indicates whether it is currently "virtual marshaling" or "mechanical marshaling";

[0095] Marshalling process status: set to "pending marshalling";

[0096] Position status of marshaling train: indicated as "following train";

[0097] To marshal another car group number: fill in the "corresponding leading car group number";

[0098] Destination of another vehicle in the marshaling: Fill in the “corresponding destination of the lead vehicle”;

[0099] Until the train is completed.

[0100] After the train is marshaled, only the leading car is retained to report the marshaling information status to the platform passenger information system, while the following car no longer sends information. Its marshaling information status is as follows:

[0101] Marshalling status: indicates whether it is currently "virtual marshaling" or "mechanical marshaling";

[0102] Marshalling process status: set to "marshaling operation";

[0103] Position status of marshaling train: indicated as “leading train”;

[0104] Marshalling another car group number: fill in the "corresponding following car group number";

[0105] Destination of another vehicle: Fill in the "destination of the corresponding following vehicle";

[0106] This information will be retained until the lead car of the marshaling group leaves the marshaling platform.

[0107] For example, in the scenario where the train runs to the platform in a virtual marshaling or mechanical marshaling state, only the marshaling information state reported by the marshaling leading car to the platform passenger information system is retained, and the marshaling following car no longer sends information, and its marshaling information state is as follows:

[0108] Marshalling status: indicates whether it is currently "virtual marshaling" or "mechanical marshaling";

[0109] Marshalling process status: set to "marshaling operation";

[0110] Position status of marshaling train: indicated as “leading train”;

[0111] Marshalling another car group number: fill in the corresponding car group number of the following car;

[0112] Destination of another vehicle: fill in the destination of the corresponding following vehicle;

[0113] This information will be retained until the lead car of the marshaling group leaves the marshaling platform.

[0114] For example, when a marshaling train enters the disassembling platform, the platform passenger information system needs to display information according to the marshaling operation status. At this time, only the marshaling information status reported by the marshaling leading car to the platform passenger information system should be retained, and the marshaling following car no longer sends information. Its marshaling information status is as follows:

[0115] Marshalling status: indicates whether it is currently "virtual marshaling" or "mechanical marshaling";

[0116] Marshalling process status: set to "marshaling operation";

[0117] Position status of marshaling train: indicated as “leading train”;

[0118] Marshalling another car group number: fill in the corresponding car group number of the following car;

[0119] Destination of another vehicle: fill in the destination of the corresponding following vehicle;

[0120] This information will be retained until the train is disassembled.

[0121] When the marshaling train has stopped and the disassembly is completed, only the leading car of the marshaling train will be retained to report the marshaling information status to the platform passenger information system. However, at this time, the marshaling process status should be updated to "pending disassembly", and this status will continue until the front of the leading car of the marshaling train is pushed out of the platform.

[0122] When the leading car of the unmarshaled group is pushed out of the platform, the information of the leading car of the group is no longer sent. At this time, the following car of the group reports the group information status to the platform passenger information system and updates it as follows:

[0123] Marshalling status: still "virtual marshaling" or "mechanical marshaling";

[0124] Marshalling process status: remain as "pending for unmarshaling" (this status remains unchanged before the locomotive leaves the platform);

[0125] The position status of the marshaling train: updated to "following train";

[0126] Marshalling another car group number: set to the default value (indicates that there is no other car information at present);

[0127] Marshalling another car destination: set to the default value (indicates that there is no other car information at present);

[0128] This information will be retained until the locomotive of the following train also leaves the platform.

[0129] For example, when the unit train arrives at the platform in a single-vehicle state, the unit train reports the marshaling information state to the platform passenger information system as follows:

[0130] Marshalling status: set to the default value (since the train is in a single-car state, this field is mainly used to distinguish whether the train is in a marshaling state. Setting it to the default value or mark indicates that the train is not currently in any specific marshaling form in the marshaling process);

[0131] Marshalling process status: remain as "non-marshaling" (this status remains unchanged before the locomotive leaves the platform);

[0132] Train formation position status: set to default value;

[0133] Marshalling another car group number: set to the default value (indicates that there is no other car information at present);

[0134] Marshalling another car destination: set to the default value (indicates that there is no other car information at present);

[0135] This information will be retained until the lead car leaves the marshaling platform.

[0136] S150, the platform passenger information system displays the operation information of the flexible marshaling train based on the received and summarized marshaling information status.

[0137] Exemplarily, the platform passenger information system summarizes the received marshaling information to form a complete train marshaling information database, which not only contains the marshaling status of the current train, but also records the historical marshaling records of the train, providing passengers with comprehensive train operation information.

[0138] The platform passenger information system displays the operation information of flexible trains to passengers through display screens, mobile applications and other channels in the station, and predicts and displays the arrival time of trains based on the train operation plan and real-time location, providing travel references for passengers. For marshaled trains, the train number and destination information of each train group can also be displayed to help passengers choose the correct car and line. The platform passenger information system dynamically updates the train operation information on the display interface through the updated information of the train control system received in real time, which also ensures the accuracy and timeliness of the information.

[0139] Through the above method, we can solve the problem that the traditional platform passenger information system does not have the advance information for announcing flexible train operations, so that it can realize effective management and real-time update of train marshaling information in a complex and changeable train operation environment, especially in scenarios where train marshaling and disassembly are flexible and changeable, and provide accurate and timely marshaling information status to the platform passenger information system, which not only improves the passengers' riding experience, but also improves the service quality and operational efficiency of rail transit.

[0140] It should be noted that, for the aforementioned method embodiments, for the sake of simplicity, they are all described as a series of action combinations, but those skilled in the art should be aware that the present disclosure is not limited by the order of the actions described, because according to the present disclosure, certain steps can be performed in other orders or simultaneously. Secondly, those skilled in the art should also be aware that the embodiments described in the specification are all optional embodiments, and the actions and modules involved are not necessarily required by the present disclosure.
