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 method for a non-fully automatic yard. Background Art

[0002] In the urban rail transit industry, the yard, as an integral and important part, plays a vital role in daily operations and management. However, many current yards are not fully automated and still have certain problems in receiving and sending vehicles.

[0003] Currently, a combination of partial automation and manual operation is often used to implement non-fully automated yard dispatching and receiving vehicles, relying on manual intervention and operation at certain stages. This model offers a certain degree of flexibility in actual operations, but also presents corresponding efficiency and accuracy issues, which are particularly prominent in situations with high business volumes and frequent operations.

[0004] In the current, non-fully automated yard vehicle dispatching and receiving process, core tasks such as planning, vehicle scheduling, and departure management can be handled by the system's automated functions. However, due to the system's low level of automation, manual input and adjustments are still required for scheduling adjustments and departure time changes. While this model can accommodate flexible scheduling needs, it is labor-intensive. The system can only perform automated operations within a pre-defined planning framework and cannot achieve dynamic, real-time automatic adjustments.

[0005] Similarly, due to the system's low level of automation, operators frequently have to participate in various stages of the plan adjustment and execution process, which not only increases the workload but also easily leads to human error. Faced with the increasingly complex demands of railway business, the existing system's capabilities in data integration, automated scheduling, and intelligent early warning are insufficient. For example, when handling complex scenarios such as temporary train schedules and emergency dispatch, the system often fails to respond promptly and effectively, still requiring human decision-making and intervention.

[0006] Furthermore, in non-fully automated yards, information transmission and feedback rely on manual communication and inter-system data integration. This model results in inefficient information transmission, particularly between the dispatch center and on-site operators, which is prone to information lags and delayed instruction delivery. This directly impacts yard operational efficiency, especially in emergency dispatch scenarios, where response speed is insufficient and inflexible.

[0007] The statements herein merely provide background information 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 train sending and receiving system and method for non-fully automatic yards, which can automate the train sending and receiving, scheduling, management and other tasks in non-fully automatic yards, thereby improving the efficiency, accuracy and safety of the yard's train 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 to the maintenance system, construction system, signal system, train ATS system and 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 generating 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 to the communication module, the available vehicle list generating module and the execution management module, and is used to make a plan for sending and receiving vehicles, and send the completed plan to the communication module and the execution management module. The communication module also sends the 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 train sending and receiving plan; the track information includes the equipment status in the track and the track occupancy status; the train status information includes the train operation information and the train equipment status information.

[0015] Preferably, the automatic vehicle sending and receiving system for non-fully automatic yards 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, and the available vehicle list, available track list and vehicle sending and receiving plan displayed therein can be fine-tuned through the operation window.

[0016] The present invention also proposes a method for automatically sending and receiving vehicles for a non-fully automated yard, which uses the automatic sending and receiving vehicle system for a non-fully automated yard, and includes 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 yard 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 planning module automatically generates a train dispatching and receiving plan based on the current day's train operation diagram 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 vehicle sending and receiving plan to the interlocking system to execute the vehicle sending and receiving plan; at the same time, the plan is also sent to the execution management module so that the execution management module monitors the execution of the vehicle sending and receiving 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 includes 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 the information 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. Based on 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 built-in priority rule. Then, the planning module sorts all trains L in the available train list according to the order of priority P(l) to obtain 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 state. According to the above formula, the train plan Plan(l)=(l,t * The receiving and dispatching time is determined based on the running time of the train in the daily operation diagram l;

[0030] S223, determine track t for each train l in the available train list in sequence according to priority. * The train dispatching and receiving time are combined to form the train dispatching and receiving plan set Schedule = {Plan(l)|l∈L′} for the day. The train dispatching and receiving plan set 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 the information 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 the information 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 track equipment status is abnormal, causing the train or track to be unavailable, 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 includes the following steps:

[0034] S31, after the plan making module generates the dispatching and receiving plan, the plan is displayed on the operation window for confirmation by the dispatcher, and the dispatching and receiving plan is then sent to the execution management module and to the interlocking system via the communication module;

[0035] S32: After receiving the train dispatching and receiving plan, the interlocking system executes it as the basic entry and exit plan for the day. According to the train dispatching and receiving plan, the corresponding entry and exit operations are performed at the corresponding time to ensure smooth entry and exit of trains.

[0036] Among them, when the interlocking system executes the train sending and receiving plan, the communication module obtains track information and train operation information in real time and sends it to the execution management module. The execution management module monitors the execution of the train sending and receiving plan based on the track information and 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 train 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 vehicle receiving and dispatching 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 in real time to monitor the operation of the train and whether the operation of the track equipment in the yard complies 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 does not comply with the plan, the adjustment requirements and reasons for the adjustment are sent to the planning module, so that the planning module adjusts the train sending and receiving plan; the planning module adopts different adjustment strategies according to the urgency and impact range of the adjustment reason.

[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 train sending and receiving plan and the adjustment of the train sending and receiving plan; during the execution of the train sending and receiving 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, an early 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 that 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 through 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 that integrates multi-source data provides strong support for the accurate generation and efficient execution of vehicle dispatching and sending plans, while also improving the automation level of the system.

[0042] In this technical solution, when generating a train dispatching and receiving plan, 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 train dispatching and receiving tasks are carried out in compliance with safety regulations, and greatly reduce the risk of accidents during plan execution.

[0043] During train operation, this technical solution can receive real-time monitoring of train status and track equipment status, and automatically adjust the dispatch and receive train schedule based on emergencies (such as train delays and equipment failures). The system can automatically select different adjustment strategies based on 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. This significantly improves the system's dynamic response capabilities and operational reliability. Through a variety of automatic adjustment strategies, emergencies can be handled in a timely manner, reducing the risk of train operation interruptions and ensuring scheduling continuity. In addition, automatic adjustment is combined with a manual confirmation mechanism to ensure that the optimal solution can be provided even in complex situations, improving overall emergency response efficiency.

[0044] This technical solution features reminder and early warning capabilities, enabling real-time monitoring of equipment status and train safety factors. When an anomaly is detected, it automatically issues an alarm and requests human intervention to ensure safe train operation. These real-time reminders and early warnings prevent potential safety hazards caused by operational errors or equipment failures, reducing the risk of accidents. Furthermore, operators receive timely task progress alerts, ensuring timely completion of tasks, further enhancing controllability and safety. BRIEF DESCRIPTION OF THE DRAWINGS

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

[0047] The following will be combined with the embodiment of the present invention Figures 1 and 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 should still fall within the scope of the technical content disclosed in the present invention without affecting the efficacy and purpose that can be achieved by the present invention.

[0049] It should be noted that, in the present invention, relational terms such as first and second, etc. are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus comprising a series of elements includes not only the elements explicitly listed, but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus.

[0050] At present, in non-fully automated 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 heavy operational workload when facing scheduling adjustments and departure time changes, inability to respond promptly and effectively to complex scenarios such as temporary trains and emergency dispatches, as well 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 automated yards. By introducing a multi-source data integration mechanism, it automatically synchronizes the plan information of multiple systems, reduces the workload of manual input, and improves the reliability of the generated dispatching and receiving plans by automatically generating and detecting dispatching and receiving plans. In addition, by setting an automatic adjustment strategy, the emergency handling efficiency of the system is improved.

[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 according to an embodiment of the present invention is as follows: 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 connects to multiple data sources to obtain information about trains and track equipment. Specifically, the communication module interfaces with both the maintenance and construction systems, automatically synchronizing the maintenance plan in the maintenance system with the construction plan in the construction system. It also interfaces with the yard's signaling system to obtain the day's train schedule and track information. It also interfaces with the train's Automatic Train Supervision (ATS) system, communicating 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 braking 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 planning module is connected to the communication module and the available vehicle list generation module. It receives train operation information from the daily train timetable sent by the communication module, the available vehicle list and available track list sent by the available vehicle list generation module, and formulates a train dispatch and reception plan. The planning module also receives real-time track information, real-time maintenance and construction plans, and real-time train status information from the communication module to dynamically adjust the dispatch and reception plan. After completing the dispatch and reception plan, the planning module sends it to the communication module for subsequent execution.

[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 planning module, which transmits the dispatch and reception plan to the execution management module, enabling it to generate corresponding alerts to assist in executing the plan. The execution management module is also connected to the communication module, which receives track information and train status information to monitor the accurate execution of the dispatch and reception plan. If issues arise during the execution of the dispatch and reception plan and adjustments are required, the execution management module sends the adjustment request and reason to the planning module. The execution management module also generates alerts to prompt action.

[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 vehicle dispatching and receiving plan displayed.

[0061] Based on the above-mentioned automatic vehicle receiving and dispatching system for non-fully automated yards, this embodiment also proposes an automatic vehicle receiving and dispatching method for non-fully automated yards, 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 planning module automatically generates a train dispatching and receiving plan based on the signal system information, the available car list and the available track list, and 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 a task request from the dispatch center, the communication module automatically synchronizes the maintenance plan for the maintenance system and the construction plan for the construction system within the depot and transmits them to the available vehicle list generation module. Based on these maintenance and construction plans, the available vehicle list generation module determines which trains and tracks can be used for dispatching and receiving trains, thereby generating a list of available vehicles and a list of available tracks. For example, if a train is under maintenance on a track, the available vehicle list will not include that train, nor will the track be included in the available track list. This allows the subsequent generation of the automatic dispatching and receiving train plan to accurately reflect the actual situation and avoid the use of tracks or trains under maintenance.

[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. In the automatic train dispatching and receiving system's operation window, the generated available car list and available track list can be reviewed and fine-tuned based on actual needs and on-site conditions to confirm whether they meet expectations. This approach improves the system's flexibility and controllability and also enhances the accuracy of subsequent train dispatching and receiving plans. 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 based on 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 construction plan and send them to the available vehicle list generation module. Instead, the construction plan information, maintenance plan information, train information, track information, etc. are entered through the operation window of the automatic vehicle dispatching and receiving system. The available vehicle list generation module then automatically generates the available vehicle list and available track list based on this input information. Furthermore, after the available vehicle list and available track list are automatically generated, they can also be reviewed and fine-tuned in the operation window of the automatic vehicle dispatching 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. Based on the information in the train timetable for the day, the list of available trains, and the list of available tracks, the planning module automatically generates a train dispatching and receiving plan for the depot based on certain rules.

[0072] Specifically, based on priority rules, track occupancy rules, equipment and train status inspection rules, and optimal routing rules, the planning module compiles trains from the available train list into a train receiving and dispatching plan. This plan includes both a train receiving plan and a train dispatching plan, corresponding to trains returning to the depot and trains leaving the depot, respectively. Based on the train timetable, each train is individually determined to be included in the train receiving or 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 car number priority rules and track priority rules. The train car number priority rule means that the service number or train number of the train has different priorities, and the trains in the available car 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 them 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, or 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 assigning tracks to trains, priority is given to tracks that are currently unoccupied or have the fewest trains occupying them, to ensure that trains can leave or return to the depot as quickly as possible, thereby reducing train waiting time. The dynamic occupancy rule means that the occupancy status of the track is detected in real time. When the track changes from occupied to idle or is about to become idle, an outbound train or a return train is assigned to the track. 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 rules refer to checking the status of the track equipment and trains in the available track list and available car list when formulating a train dispatch and departure plan, ensuring that the assigned track equipment is normal, avoiding the use of faulty tracks, and only assigning tracks to trains in good condition, thereby ensuring the feasibility of subsequent train dispatch and departure plans. 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 maintenance plan to the plan formulation module. When the plan formulation module finds that a track or train is under maintenance or construction, it stops formulating a train dispatch and departure plan for it. When the plan formulation module finds that a track or train has completed maintenance or construction, it adds it to the available car list and available track list and formulates a train dispatch and departure plan 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 train inbound and outbound paths.

[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 built-in priority rule. Then, the planning module sorts all trains L in the available train list according to the order of priority P(l) to obtain 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, considering the path cost, track equipment status and track vacancy, the optimal track t is assigned to the train l with the highest priority. * , forming a set of train plans Plan(l)=(l,t * The train dispatching and receiving time is determined based on the train's running time in the train's daily running diagram.

[0083] S223, determine track t for each train in the available train list according to priority. * The train dispatching and receiving time are combined to form the train dispatching and receiving plan set Schedule = {Plan(l)|l∈L′} for the day. The train dispatching and receiving plan set 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 takes into account 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 receiving times have been determined for a train, and the planning module obtains updated information that the track is occupied through the communication module, it will delete the track from the list of available tracks and calculate the alternative track for the train to dispatch and receive at that time, so as to reallocate resources and update the dispatching and receiving plans.

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

[0087] In more embodiments, after the train dispatching and sending 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 train dispatching and sending plan are adjusted to complete the adjustment information and generate a new train dispatching and sending plan.

[0088] Step S3 specifically includes the following steps:

[0089] S31. After the plan-making module generates a dispatching and receiving plan, or after a new dispatching and receiving plan is generated, it is displayed on the dispatching and receiving system's operation window for the dispatcher to confirm. The confirmed dispatching and receiving plan is then sent to the execution management module and to the interlocking system via the communication module. In other embodiments, after the dispatcher confirms the plan, the communication module also sends the dispatching and receiving plan to the dispatch center for approval by an approval officer before sending it to the interlocking system and the execution management module.

[0090] S32. After receiving the train dispatching and receiving plan, the interlocking system executes it as the basic entry and exit plan for the day. Based on the time and track arrangement of the train dispatching and receiving plan, the interlocking system automatically switches the switches, controls the signals, and updates the train formation information at the corresponding times to ensure smooth entry and exit of trains.

[0091] When the interlocking system executes the train dispatching and receiving plan, the communication module communicates with the signaling system and the ATS system, obtaining real-time track information such as switch equipment and signal equipment through the signaling system, and train operation information through the ATS system. The module then sends this information to the execution management module, which compares the information sent by the signaling system with the time and track allocation in the train dispatching and receiving plan to monitor the accuracy of each operation. If the execution management module detects that the track the train is about to enter is occupied through monitoring track information, it sends an adjustment request to the planning module, which automatically adjusts and arranges a new track for the train. After adjusting the train dispatching and receiving plan, the planning module sends the new plan to the interlocking system and the execution management module, allowing the train to complete the dispatching and receiving tasks safely and orderly.

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

[0093] S4. The execution management module stores task execution status and progress for subsequent analysis and tracking. This recording and feedback mechanism ensures transparency and traceability of the vehicle delivery and collection process, helping to improve overall operational efficiency.

[0094] Furthermore, before step S32, i.e., before the interlocking system executes the train dispatching and hauling plan, the execution management module also receives real-time train status information and track information from the communication module, monitoring the train's operating status and the operation of the track equipment in the yard to see if they conform to the plan in the day's train timetable. If a train's operating status or track equipment status deviates from the plan, such as a train delay or track equipment failure, the execution management module sends an adjustment request and reason to the plan formulation module, instructing it to adjust the train dispatching and hauling plan. The plan formulation module then adopts different adjustment strategies based on the urgency and impact of the adjustment reason. For example, if a train is temporarily delayed, the train's entry and exit sequence and track information are adjusted based on step S22, and a corresponding train dispatching and hauling plan is generated. In this case, the entire train dispatching and hauling plan need not be adjusted; only the sequence and track information of the trains before and after the train need to be adjusted. If a serious track equipment failure prevents the track and train from completing the existing train dispatching and hauling plan, the plan formulation module completely re-creates a new train dispatching and hauling plan. After the plan making module adjusts or re-formulates the plan for receiving and sending vehicles, the new 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 plan for receiving and sending vehicles.

[0095] In further embodiments, the execution management module also includes reminder and warning functions to assist in the execution of train dispatch and reception plans. Specifically, the execution management module displays departure reminders and plan adjustment reminders in the system's operation window based on the time and adjustments in the train dispatch and reception plan, ensuring that staff can make relevant preparations in a timely manner and ensure that tasks are executed on time. During the execution of the train dispatch and reception plan, if the execution management module monitors that the track the train is about to enter is occupied and sends an adjustment request to the planning module, a warning message will also be displayed in the operation window to prompt the operator to conduct maintenance or adjustments.

[0096] Furthermore, during the execution of the plan, the communication module also obtains train operation information and track equipment status information such as the safe 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 safe 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.

[0097] Although the present invention has been described in detail through the above preferred embodiments, it should be understood that the above description is not intended to limit the present invention. After reading the above description, various modifications and substitutions of the present invention will become apparent to those skilled in the art. Therefore, the scope of protection of the present invention should be defined by the appended claims.
