Description

Technical Field

[0001] The present invention relates to the field of train sending and receiving vehicles, and in particular to an automatic sending and receiving vehicle system and a sending and receiving vehicle method for a non-fully automatic yard. Background Art

[0002] In the urban rail transit industry, the yard, as an important and inseparable part, plays a vital role in daily work and operation. Among the existing yards, there are still many non-fully automatic yards that have certain problems in receiving and sending vehicles.

[0003] At present, the mode of combining partial automation with manual operation is mostly used to realize non-fully automatic yard dispatching and receiving vehicles, and manual intervention and operation are relied on in some links. This mode has certain flexibility in actual operation, but it also has corresponding efficiency and accuracy problems, especially in the case of large business volume and frequent operations.

[0004] In the current non-automatic yard vehicle receiving and dispatching process, in the core links such as plan preparation, vehicle dispatching, and dispatch management, some work can be handled by the system's automation function. However, due to the low degree of system automation, when it comes to operations such as dispatching adjustments and departure time changes, operators still need to manually input and adjust. Although this mode can adapt to flexible dispatching needs, the workload of the operation is large, and the system can only complete automated operations within the established planning framework, and cannot achieve dynamic real-time automatic adjustments.

[0005] Also, due to the low degree of automation of the system, operators frequently participate in various links of the plan adjustment and execution process, which not only increases the workload but also easily leads to human errors. Faced with the increasingly complex railway business needs, the existing system is insufficient in data integration, automated scheduling, intelligent early warning and other aspects. For example, when dealing with complex scenarios such as temporary trains and emergency scheduling, the system often cannot respond effectively and in a timely manner, and still requires manual decision-making and intervention.

[0006] Moreover, in non-automatic sites, the transmission and feedback of information depends on manual communication and data connection between systems. This mode results in low timeliness of information transmission, especially in the communication between the dispatch center and on-site operators, which is prone to problems such as information lag and untimely instruction transmission. This directly affects the operational efficiency of the site, especially in the scenario of emergency dispatch, the response speed is not fast and flexible enough.

[0007] The statements herein merely provide background art related to the present invention and do not necessarily constitute prior art. Summary of the invention

[0008] Based on the above problems, the purpose of the present invention is to propose an automatic vehicle sending and receiving system and vehicle sending and receiving method for a non-fully automatic yard, which can automate the train sending and receiving, scheduling, management and other tasks in the non-fully automatic yard, thereby improving the efficiency, accuracy and safety of the yard's vehicle sending and receiving, effectively reducing the burden of manual operation, reducing operational errors, and improving emergency response capabilities.

[0009] To achieve the above-mentioned purpose, the present invention proposes an automatic vehicle receiving and dispatching system for non-fully automatic yards, comprising: a communication module, an available vehicle list generation module, a plan formulation module and an execution management module;

[0010] The communication module is connected with the maintenance system, the construction system, the signal system, the train ATS system and the interlocking system, and is used to obtain the maintenance plan in the maintenance system, the construction plan in the construction system, the train operation diagram of the day, track information and train status information;

[0011] The available vehicle list generation module is connected to the communication module and is used to generate an available vehicle list and an available track list according to the maintenance plan and the construction plan;

[0012] The plan making module is connected with the communication module, the available vehicle list generating module and the execution management module, and is used to make a vehicle sending and receiving plan, and send the completed vehicle sending and receiving plan to the communication module and the execution management module, and the communication module also sends the vehicle sending and receiving plan to the interlocking system;

[0013] The execution management module is also connected to the communication module and is used to obtain track information and train status information in real time, so as to monitor the execution process of the train sending and receiving plan.

[0014] Preferably, the planning module also receives the real-time track information, the maintenance plan, the construction plan, and the train status information sent by the communication module to dynamically adjust the vehicle sending and receiving plan; the track information includes the equipment status and track occupancy status in the track; the train status information includes train operation information and train equipment status information.

[0015] Preferably, the automatic vehicle sending and receiving system for a non-fully-automatic yard section also has an operation window, which is used to display the available vehicle list, the available track list and the vehicle sending and receiving plan; the operation window also has an interactive function, through which the available vehicle list, available track list and vehicle sending and receiving plan displayed can be fine-tuned.

[0016] The present invention also proposes an automatic vehicle receiving and dispatching method for a non-fully automatic yard section, using the automatic vehicle receiving and dispatching system for a non-fully automatic yard section, comprising the following steps:

[0017] S1. The communication module automatically synchronizes the maintenance plan of the maintenance system and the construction plan of the construction system in the field section, and sends them to the available vehicle list generation module; the available vehicle list generation module generates an available vehicle list and an available track list based on the maintenance plan and the construction plan;

[0018] S2, the plan making module automatically generates the train's dispatching and sending plan according to the train operation diagram of the day in the signal system, the available car list and the available track list, and based on certain algorithm design rules;

[0019] S3. The plan formulation module sends the generated sending and receiving vehicle plan to the interlocking system to execute the sending and receiving vehicle plan; at the same time, the sending and receiving vehicle plan is also sent to the execution management module, so that the execution management module monitors the execution of the sending and receiving vehicle plan.

[0020] Preferably, in step S1, after being generated, the available vehicle list and the available track list are also displayed on the operation window, and the available vehicle list and the available track list are adjusted according to actual conditions.

[0021] Preferably, step S2 comprises the following steps:

[0022] S21, the communication module obtains the train operation diagram of the day from the signal system, obtains the train number, service number and corresponding outbound track and inbound track information of the train running on the day, and sends it to the planning module;

[0023] The available vehicle list generating module sends the available vehicle list and the available track list to the planning module;

[0024] S22. According to the information in the daily operation diagram, the available vehicle list and the available track list, the planning module automatically generates a train dispatching and receiving plan for the yard based on priority rules, track occupancy rules, equipment and train status inspection rules, and path optimization rules.

[0025] Preferably, step S22 includes the following steps:

[0026] S221. For all trains L in the available train list, the planning module assigns a corresponding priority P(l) to each train according to the priority rule built therein, and then sorts all trains L in the available train list according to the priority P(l), and obtains L′=Sort(L, by P(l));

[0027] S222. For the train l with the highest priority in L′, assign it track t. * And the time of sending and receiving vehicles:

[0028] t * = arg min t∈T {C(l,t)+ω1·(1-S(t))+ω2·O(t,t now )}

[0029] Among them, ω1 and ω2 are weight parameters used to balance path cost, device status and occupancy, C(l, t) is the path cost, S(t) is the device status, O(t, t now ) is the track occupancy status. According to the above formula, the train plan Plan(l)=(l,t * ); the train dispatching and receiving time is determined based on the running time l of the train in the running diagram of the day;

[0030] S223, determining track t for each train l in the available train list in sequence according to the priority sorting. * The train dispatching and receiving time form the train dispatching and receiving plan set Schedule = {Plan (l) | l∈L′} for the day, which includes the time for each train to leave or return to the depot and the corresponding departure track or return track.

[0031] Preferably, in step S22, the communication module communicates with the signal system in real time to obtain real-time track equipment status and track occupancy status, and sends them to the planning module; the communication module also communicates with the train ATS system in real time to obtain real-time train status information and sends it to the planning module;

[0032] When the plan making module finds, based on the real-time track equipment status, track occupancy status and train status information, that there is a track occupancy conflict in the generated train dispatching and receiving plan, the train departure time overlaps with the arrival time, or the train or track is unavailable due to abnormal track equipment status, the generation of the train dispatching and receiving plan will be stopped, and the detailed cause of the conflict will be displayed in the operation window.

[0033] Preferably, step S3 comprises the following steps:

[0034] S31, after the plan making module generates the sending and receiving vehicle plan, the sending and receiving vehicle plan is displayed on the operation window for the dispatcher to confirm, and then the confirmed sending and receiving vehicle plan is sent to the execution management module and to the interlocking system through the communication module;

[0035] S32, after receiving the train dispatching and receiving plan, the interlocking system executes it as the basic in-and-out plan for the day, and performs corresponding in-and-out operations at corresponding times according to the train dispatching and receiving plan, so that the train can enter and exit the warehouse smoothly;

[0036] Among them, when the interlocking system executes the vehicle sending and receiving plan, the communication module obtains the track information and the train operation information in real time, and sends it to the execution management module, and the execution management module monitors the execution of the vehicle sending and receiving plan according to the track information and the train operation information; when the execution management module monitors that the track that the train is about to enter is occupied, it sends an adjustment request to the plan making module, so that the plan making module automatically adjusts the vehicle sending and receiving plan.

[0037] Preferably, after step S3, the method further includes: S4, the execution management module stores the execution status and process of the receiving and dispatching vehicle plan for subsequent analysis and tracking.

[0038] Preferably, before step S32, the execution management module also receives real-time train status information and real-time track information sent by the communication module to monitor whether the operation of the train and the operation of the track equipment in the yard are in line with the plan in the train operation diagram of the day. Once it is found that the operation of the train or the operation of the track equipment is inconsistent with the plan, the adjustment requirements and reasons for the adjustment are sent to the planning module, so that the planning module adjusts the plan for receiving and sending vehicles; the planning module adopts different adjustment strategies according to the urgency and impact range of the adjustment reasons.

[0039] Preferably, the execution management module displays a departure reminder and a plan adjustment reminder on the operation window according to the time in the sending and receiving train plan and the adjustment of the sending and receiving train plan; during the execution of the sending and receiving train plan, when the execution management module monitors that the track that the train is about to enter is occupied and sends an adjustment request to the plan making module, a warning message is also displayed in the operation window.

[0040] Compared with the prior art, the technical solution of the present invention has the following advantages and beneficial effects:

[0041] This technical solution introduces a multi-source data integration mechanism, which can automatically synchronize the maintenance and construction plan information in the maintenance system and the construction system, and automatically generate a list of available vehicles in combination with the status data of trains and equipment; it can also generate a list of available vehicles by manual entry. This combination of manual entry and automatic synchronization ensures the comprehensiveness and accuracy of the data, making data input more efficient and accurate; through the automatic synchronization of multi-source data, the workload and error probability of manual input are reduced, ensuring the real-time consistency of train status, equipment status and operation plan; the intelligent input mechanism integrating multi-source data provides strong support for the accurate generation and efficient execution of vehicle dispatching and sending plans, and also improves the automation level of the system.

[0042] In this technical solution, when generating a plan for sending and receiving trains, the system will automatically perform conflict detection on the plan based on multiple factors such as priority, track occupancy information, equipment and train status. If the detection fails, the system will stop generating the plan and provide feedback on the cause of the conflict to avoid erroneous plan execution, effectively improving the reliability and safety of plan generation. Through automated conflict detection, the system can prevent operational errors caused by conflicts in resources such as tracks and equipment, reduce negligence or errors that may be caused by human intervention, ensure that the tasks of sending and receiving trains are carried out in compliance with safety regulations, and greatly reduce the risk of accidents during plan execution.

[0043] During the operation of the train, this technical solution can receive real-time monitoring of the train status and track equipment status, and automatically adjust the dispatching and receiving plans according to emergencies (such as train delays and equipment failures). The system can automatically select different adjustment strategies according to the urgency of the situation, such as automatically adjusting the route sequence for short-term delays and rescheduling the overall plan for serious equipment failures, which greatly improves the system's dynamic response capabilities and operational reliability; through a variety of automatic adjustment strategies, it can handle emergencies in a timely manner, reduce the risk of train operation interruptions, and ensure the continuity of scheduling. In addition, automatic adjustment is combined with a manual confirmation mechanism to ensure that the best solution can be provided even in complex situations, improving the overall emergency handling efficiency.

[0044] This technical solution has reminder and warning functions, which can receive real-time monitoring equipment status and safety factors of train operation. When an abnormality is detected, it can automatically issue an alarm and request manual intervention to ensure the safety of train operation. Through real-time reminders and warnings, it can prevent safety hazards caused by possible operational errors or equipment failures and reduce the risk of accidents. In addition, operators can receive task progress reminders in a timely manner to ensure that various tasks are completed on time, further improving controllability and safety.

[0046] Figure 2 The present invention is a flowchart of a method for automatically sending and receiving vehicles in a non-fully automatic yard according to an embodiment of the present invention. DETAILED DESCRIPTION

[0047] The following will be combined with the embodiments of the present invention Figure 1-2 , the technical solutions, structural features, objectives achieved and effects in the embodiments of the present invention are described in detail.

[0048] 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.

[0049] 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.

[0050] At present, in non-fully automatic yards, when executing train dispatching and receiving tasks, due to the use of a combination of partial automation and manual operation, there are problems such as large operating workload when facing scheduling adjustments and departure time changes, and the problem of being unable to respond to complex scenarios such as temporary trains and emergency dispatches in a timely and effective manner, as well as problems such as low timeliness of information transmission and information lag. In order to solve the above problems, the present invention proposes an automatic dispatching and receiving system and method for non-fully automatic yards, which automatically synchronizes the planning information of multiple systems by introducing a multi-source data integration mechanism, reduces the workload of manual input, and improves the reliability of the generated dispatching and receiving plan by automatically generating and detecting the dispatching and receiving plan, and improves the emergency handling efficiency of the system by setting an automatic adjustment strategy.

[0051] The automatic vehicle sending and receiving system and vehicle sending and receiving method for a non-fully automatic yard section of the present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0052] An automatic vehicle receiving and dispatching system for a non-fully automatic yard section according to an embodiment of the present invention, such as Figure 1 As shown, it includes a communication module, an available vehicle list generation module, a plan making module and an execution management module.

[0053] The communication module is connected to multiple data sources to obtain relevant information about trains and track equipment. Specifically: the communication module is connected to both the maintenance system and the construction system through interfaces, thereby automatically synchronizing the maintenance plan in the maintenance system and the construction plan in the construction system; the communication module is also connected to the signal system of the yard through an interface to obtain the train operation diagram and track information of the day from the signal system; the communication module is also connected to the train's ATS (Automatic Train Supervision) system through an interface, and communicates in real time to obtain train status information.

[0054] The track information includes the status of track equipment (turnouts, signals, etc.), track occupancy status, etc. The train status information includes train operation information, train equipment (such as brake system, electrical system) status information, etc.

[0055] The available vehicle list generating module is connected to the communication module to receive the maintenance plan and the construction plan, and generates an available vehicle list and an available track list according to the maintenance plan and the construction plan.

[0056] The plan making module is connected with the communication module and the available car list generation module, receives the train operation information in the train operation diagram of the day sent by the communication module, the available car list and the available track list sent by the available car list generation module, and makes a train dispatching and sending plan. The plan making module also receives real-time track information, real-time maintenance plan and construction plan, and real-time train status information sent by the communication module to dynamically adjust the dispatching and sending plan. After completing the dispatching and sending plan, the plan making module sends it to the communication module for subsequent execution process.

[0057] The communication module is also connected to the interlocking system so as to send the vehicle sending and receiving plan to the interlocking system for execution.

[0058] The execution management module is connected to the plan making module, so that the plan making module sends the dispatching and receiving car plan to the execution management module, so that the execution management module generates corresponding reminder information, thereby assisting in the execution of the dispatching and receiving car plan. The execution management module is also connected to the communication module, and obtains track information and train status information through the communication module to monitor the accurate execution of the dispatching and receiving car plan. When problems arise during the execution of the dispatching and receiving car plan and adjustments are required, the execution management module also sends the adjustment requirements and reasons for the adjustment to the plan making module, and the execution management module also generates warning information to prompt the work.

[0059] The automatic vehicle sending and receiving system also has an operation window to display the available vehicle list and available track list generated by the available vehicle list generation module, the vehicle sending and receiving plan generated by the plan formulation module, and the reminder information and warning information of the execution management module.

[0060] The operation window may also be interactive, through which the staff can fine-tune the available vehicle list, available track list and receiving and dispatching vehicle plan displayed.

[0061] Based on the above-mentioned automatic vehicle receiving and dispatching system for non-fully automatic yard sections, this embodiment also proposes an automatic vehicle receiving and dispatching method for non-fully automatic yard sections, such as Figure 2 As shown, the following steps are included:

[0062] S1. The available vehicle list generation module generates an available vehicle list and an available track list based on the maintenance plan and construction plan in the yard;

[0063] S2, the plan making module automatically generates a train dispatching and receiving plan based on the information of the signal system, the available car list and the available track list, and based on certain algorithm design rules;

[0064] S3. The plan making module sends the generated sending and receiving vehicle plan to the interlocking system through the communication module to execute the sending and receiving vehicle plan, and at the same time sends the sending and receiving vehicle plan to the execution management module so that the execution management module monitors the execution of the sending and receiving vehicle plan.

[0065] In step S1, upon receiving the task requirements from the dispatching center, the communication module automatically synchronizes the maintenance plan of the maintenance system and the construction plan of the construction system in the yard section, and sends them to the available vehicle list generation module. The available vehicle list generation module determines which trains and which tracks can be used in the process of sending and receiving vehicles based on the maintenance plan and the construction plan, thereby generating an available vehicle list and an available track list. For example, when a train is under maintenance on some tracks, the available vehicle list will not include the train, and the available track list will not include the track, so that when the automatic sending and receiving vehicle plan is generated later, it can accurately follow the actual situation and avoid using maintenance tracks or trains.

[0066] The available train list includes train information such as train formation information, train number, train status information, service number, etc. of the trains that can be included in the train dispatching and receiving plan. The available track list includes the track number and track information of the tracks that can be used in the train dispatching and receiving plan.

[0067] Furthermore, in step S1, after the available car list and available track list are generated, they can be manually fine-tuned. On the operation window of the automatic vehicle dispatching and receiving system, the generated available car list and available track list are reviewed and fine-tuned according to actual needs and on-site conditions to confirm whether the available car list and available track list meet expectations. This method improves the flexibility and controllability of the system and can also improve the accuracy of the subsequent vehicle dispatching and receiving plan. For example, after the available car list and available track list are automatically generated, the dispatcher can modify the train information or track information in the available car list and available track list according to the actual train priority and track status.

[0068] In other embodiments, in step S1, the communication module does not need to obtain the maintenance plan and the construction plan and send them to the available vehicle list generation module, but inputs the construction plan information, the maintenance plan information, the train information, the track information, etc. through the operation window of the automatic vehicle sending and receiving system, so that the available vehicle list generation module automatically generates the available vehicle list and the available track list according to the input information. Furthermore, after the available vehicle list and the available track list are automatically generated, they can also be reviewed and fine-tuned on the operation window of the automatic vehicle sending and receiving system.

[0069] Step S2 specifically includes the following steps:

[0070] S21, the communication module obtains the train operation diagram of the day from the signal system, obtains the train number, service number and corresponding outbound track and inbound track information of the train running on the day, and sends it to the planning module; the available car list generation module sends the generated available car list and available track list to the planning module;

[0071] S22, according to the information in the train operation diagram of the day, the available car list and the available track list, the planning module automatically generates a train dispatching and receiving plan for the yard based on certain rules;

[0072] Specifically, based on the priority rules, track occupancy rules, equipment and train status inspection rules, and path optimization rules, the planning module compiles the trains in the available train list into the train receiving and dispatching plan. The train receiving and dispatching plan includes a train receiving plan and a train dispatching plan, which correspond to train return and train departure, respectively. According to the train operation diagram, it is confirmed one by one whether each train should be included in the train receiving plan or the train dispatching plan.

[0073] The priority rules, track occupancy rules, equipment and train status inspection rules, and path optimization rules are built into the planning module.

[0074] The priority rules include train number priority rules and track priority rules. The train number priority rule means that the service number or train number of the train has different priorities, and the trains in the available train list are sorted according to the priority, so that when formulating the train sending and receiving plan, the outbound and return paths of high-priority trains are arranged in time to avoid waiting. The track priority rule means that different tracks have different priorities. For example, tracks close to entrances and exits have high priorities, and tracks far from entrances and exits have low priorities. Alternatively, other track priority rules can be used to assign corresponding priorities to each track and sort them according to priority.

[0075] The track occupancy rules include minimum occupancy rules and dynamic occupancy rules. The minimum occupancy rule means that when allocating tracks to trains, priority is given to the tracks that are currently unoccupied or occupied by the least trains, so as to ensure that the trains can leave the depot or return to the depot as soon as possible, thereby reducing the waiting time of the trains. The dynamic occupancy rule means that the occupancy of the track is detected in real time, and when the track changes from occupied to idle or is about to become idle, an outbound train or a return train is allocated to the track. Among them, the communication module communicates with the signal system in real time to obtain the track occupancy status and sends it to the planning module.

[0076] The equipment and train status check rule means that when making a plan for sending and receiving trains, the status of the track equipment and trains in the available track list and the available car list are checked to ensure that the assigned track equipment is normal, avoid using faulty tracks, and only assign tracks to trains in good condition, so as to ensure the feasibility of subsequent plans for sending and receiving trains. The communication module collects the construction plan of the construction system and the maintenance plan of the maintenance system in real time and sends the updated data in the construction plan and the maintenance plan to the plan making module. When the plan making module finds that a track or train is under maintenance or construction, it stops making plans for sending and receiving trains for it; and when the plan making module finds that a track or train has finished maintenance or construction, it includes it in the available car list and the available track list, and makes plans for sending and receiving trains for it.

[0077] The optimal path rule means that when selecting tracks for trains, priority is given to outbound and return paths with short paths and few intersections, thereby shortening the inbound and outbound paths of trains.

[0078] Therefore, step S22 specifically includes the following steps:

[0079] S221. For all trains L in the available train list, the planning module assigns a corresponding priority P(l) to each train according to the priority rule built therein, and then sorts all trains L in the available train list according to the priority P(l), and obtains L′=Sort(L, by P(l));

[0080] S222. For the train l with the highest priority in L′, assign it track t. * and pick-up and dispatch times;

[0081] t * = arg min t∈T {C(l,t)+ω1·(1-S(t))+ω2·O(t,t now )}

[0082] Among them, ω1 and ω2 are weight parameters used to balance path cost, device status and occupancy. C(l, t) is the path cost, S(t) is the device status, O(t, t now ) is the track occupancy status. According to the above formula, the optimal track t is allocated to the train l with the highest priority by comprehensively considering the path cost, track equipment status and track idleness. * , forming a set of train plans Plan(l)=(l,t * ). The train receiving and dispatching time is determined based on the train's running time in the train's daily running diagram.

[0083] S223, determine the track t for each train in the available train list in turn according to the priority * The train dispatching and receiving time form the train dispatching and receiving plan set Schedule = {Plan (l) | l∈L′} for the day, which includes the time for each train to leave or return to the depot and the corresponding departure track or return track.

[0084] The train dispatching and receiving plan generated according to the above steps comprehensively considers the train priority, track occupancy information, etc., to ensure that the generated plan is optimally allocated in terms of time and track.

[0085] In the above process, if the track and the corresponding dispatching and sending time have been determined for a train, and the planning module obtains the updated information that the track is occupied through the communication module, the track will be deleted from the list of available tracks, and an alternative track for the train to dispatch and send at that time will be calculated to reallocate resources and update the dispatching and sending plan.

[0086] Further, in step S22, while the plan making module generates the dispatching and receiving car plan, it also performs conflict detection on the dispatching and receiving car plan. Specifically, the communication module communicates with the signal system in real time to obtain track information such as real-time track equipment status and track occupancy status, and sends it to the plan making module. The communication module also communicates with the train ATS system in real time to obtain real-time train status information and sends it to the plan making module. Since the track equipment status, occupancy status and train status information change in real time, when the plan making module finds that there is a track occupancy conflict in the generated dispatching and receiving car plan, the train departure time overlaps with the arrival time, the track equipment status is abnormal, and other problems cause the train or track to be unavailable, the dispatching and receiving car plan is stopped, and a detailed conflict reason is provided and displayed in the system's operation window to remind the dispatcher. The dispatcher can view the conflict reason in the operation window, and adjust the relevant parameters to resolve the conflict, or make the system re-formulate the dispatching and receiving car plan.

[0087] In more embodiments, after the sending and receiving car plan is formulated, it can also be fine-tuned manually. In the system operation window, the dispatcher can input adjustment information such as adjusting the train sequence and adjusting the track allocation. When the plan formulation module receives the adjustment information, based on step S22, the trains that need to be adjusted in the sending and receiving car plan are adjusted to complete the adjustment information and generate a new sending and receiving car plan.

[0088] Step S3 specifically includes the following steps:

[0089] S31. After the plan making module generates the dispatching and sending plan, or after generating a new dispatching and sending plan, it is displayed on the operation window of the dispatching and sending system for the dispatcher to confirm, and then the confirmed dispatching and sending plan is sent to the execution management module, and sent to the interlocking system through the communication module. In other embodiments, after the dispatcher confirms, the communication module also sends the dispatching and sending plan to the dispatch center, for the approval personnel to confirm, and then sent to the interlocking system and the execution management module;

[0090] S32, after receiving the train dispatching and receiving plan, the interlocking system will execute it as the basic entry and exit plan for the day. According to the time and track arrangement of the train dispatching and receiving plan, the interlocking system will automatically switch the turnout, control the signal, update the train formation information and other entry and exit operations at the corresponding time to ensure the smooth entry and exit of the train;

[0091] Among them, when the interlocking system executes the train dispatching and receiving plan, the communication module communicates with the signal system and the ATS system, obtains track information such as turnout equipment and signal equipment in real time through the signal system, obtains train operation information in real time through the ATS system, and sends it to the execution management module. The execution management module compares the information sent by the signal system with the time and track allocation in the train dispatching and receiving plan to monitor the accuracy of each step of the operation. When the execution management module monitors the track information to find that the track that the train is about to enter is occupied, it sends an adjustment request to the plan making module, so that the plan making module automatically adjusts and arranges a new track for the train. After the plan making module adjusts the train dispatching and receiving plan, it sends the new train dispatching and receiving plan to the interlocking system and the execution management module, so that the train can complete the train dispatching and receiving task safely and orderly.

[0092] Finally, when the train has a task of receiving or sending a train, that is, after step S3, the following steps are also included:

[0093] S4. The execution management module stores the task execution status and process for subsequent analysis and tracking. Through this recording and feedback mechanism, the transparency and traceability of the vehicle receiving and dispatching process are ensured, which helps to improve the overall operational efficiency.

[0094] Furthermore, before step S32, that is, before the interlocking system executes the vehicle dispatching and sending plan, the execution management module also receives the real-time train status information and real-time track information sent by the communication module in real time, monitors the operation of the train and the operation of the track equipment in the yard in real time to see whether it conforms to the plan in the train operation diagram of the day. Once it is found that the train operation or the track equipment operation is inconsistent with the plan, such as train delays, track equipment failures, etc., the execution management module sends the adjustment requirements and adjustment reasons to the plan formulation module, so that the plan formulation module adjusts the vehicle dispatching and sending plan. The plan formulation module adopts different adjustment strategies according to the urgency and impact range of the adjustment reasons. For example, for a short-term train delay, based on step S22, the train's in-and-out order and track are adjusted, and the corresponding vehicle dispatching and sending plan is generated. At this time, there is no need to adjust the entire vehicle dispatching and sending plan, only the train order and track before and after the train need to be adjusted; and for the situation where the track equipment is seriously faulty, so that the track and the train cannot complete the existing vehicle dispatching and sending plan, the plan formulation module completely re-formulates a new vehicle dispatching and sending plan. After the plan making module adjusts or re-formulates the vehicle receiving and dispatching plan, the new vehicle receiving and dispatching plan will be displayed in the operation window for manual confirmation or fine-tuning before being sent to the interlocking system and execution management module, so that the interlocking system and execution management module can execute the new vehicle receiving and dispatching plan.

[0095] In more embodiments, the execution management module also has reminder and warning functions to assist in the execution of the dispatching and sending plan. Specifically, the execution management module displays the dispatching reminder, plan adjustment reminder, etc. on the system operation window according to the time in the dispatching and sending plan and the adjustment of the dispatching and sending plan, to ensure that the staff can make relevant preparations in time and ensure that the task is executed on time; during the execution of the dispatching and sending plan, when the execution management module monitors that the track that the train is about to enter is occupied and sends an adjustment request to the plan making module, it also displays a warning message in the operation window to prompt the operator to inspect or adjust.

[0096] Furthermore, during the execution of the plan, the communication module also obtains train operation information and track equipment status information such as the safety distance between trains and train signal status from the ATS system, and sends it to the execution management module, so that the execution management module monitors the equipment signals, power and train operation safety distance, etc. When an abnormality is detected (signal failure, power abnormality, insufficient safety distance), the execution management module issues an alarm through the operation window to prompt the operator to take corresponding safety measures.
