Description

Technical Field

[0001] The present disclosure relates to the technical field of rail vehicle scheduling and management, and more specifically, to a vehicle maintenance scheduling method, device, and train based on a vehicle-ground integrated system. Background Art

[0002] Under traditional electromechanical system integration, each discipline, such as vehicles, signals, and yards, is designed independently, information is isolated, and control is decentralized. Regarding rail vehicle maintenance, the current conventional urban rail ground maintenance system has separate functions for train dispatching, section dispatching, and yard dispatching. When a vehicle malfunctions, manual communication is required for dispatching, resulting in low efficiency for both vehicle maintenance and operational scheduling. Furthermore, the lack of interaction between vehicle maintenance and operational data creates information silos, leading to delayed feedback on maintenance status, significant site occupancy issues, and increasing maintenance costs year after year. Summary of the Invention

[0007] According to an embodiment of the present disclosure, each maintenance duration is generated based on the information of each component to be repaired and the historical maintenance information, including: for each component to be repaired, extracting the vehicle model information on which the component to be repaired has been assembled from the information of the component to be repaired; determining at least one historical maintenance duration corresponding to the vehicle model information and the information of the component to be repaired from the historical maintenance information; and calculating the maintenance duration based on the at least one historical maintenance duration.

[0008] According to an embodiment of the present disclosure, the above method further includes: determining candidate tracks corresponding to information of each component to be repaired; and determining a target track from the candidate tracks based on operation status information on each candidate track.

[0009] According to an embodiment of the present disclosure, based on the maintenance scheduling strategy information, each vehicle is scheduled to enter the ground maintenance and repair site according to its corresponding track information to wait for maintenance, including: determining the track information for each vehicle to enter its corresponding track and the time information of each vehicle arriving at the ground maintenance site based on the maintenance scheduling strategy information; sending the time information of each vehicle arriving at the ground maintenance site and the track information for each vehicle to enter its corresponding track to each vehicle, so that each vehicle can generate a vehicle operation control strategy based on the time information, track information and operation status information of each vehicle to control each vehicle to enter the ground maintenance and repair site according to its corresponding track information to wait for maintenance.

[0010] According to an embodiment of the present disclosure, the historical mileage of each vehicle and the initial fault diagnosis information of each vehicle are analyzed to determine the information of each component to be repaired, including: in response to the historical mileage being greater than a predetermined threshold, determining that the component to be repaired is a traction motor bearing; and in response to the historical mileage being less than or equal to a predetermined threshold and the initial fault diagnosis information being a traction motor grounding, determining that the component to be repaired is a traction motor.

[0011] Another aspect of the present disclosure provides a vehicle maintenance scheduling device based on a vehicle-body integrated system, comprising: a first acquisition module for acquiring operating status information, initial fault diagnosis information and ground maintenance operation status information of multiple vehicles; wherein the operating status information includes operating position, operating speed and historical operating mileage; an analysis module for analyzing the historical operating mileage of each vehicle and the initial fault diagnosis information of each vehicle to determine the information of each component to be repaired; a calculation module for calculating the driving time required for each vehicle to reach a ground maintenance site according to the operating position of each vehicle and the operating speed of each vehicle; a generation module for generating maintenance scheduling strategy information for multiple vehicles based on the information of each component to be repaired, each driving time and ground maintenance operation status information; wherein the maintenance scheduling strategy information indicates the track information of each vehicle when waiting for maintenance at the ground maintenance site; and a scheduling module for scheduling each vehicle to enter the ground maintenance site according to its corresponding track information to wait for maintenance based on the maintenance scheduling strategy information.

[0016] According to an embodiment of the present disclosure, a vehicle-ground integrated system promptly acquires vehicle operating status information, initial fault diagnosis information, and ground maintenance operation status information. Based on this information, information about components to be repaired can be determined, and the time required for the vehicle to arrive at the ground maintenance site can be calculated. A vehicle maintenance scheduling strategy is generated based on the aforementioned information about components to be repaired, the time required to arrive at the ground maintenance site, and the ground maintenance operation status information. The vehicle is scheduled according to the scheduling strategy and awaits repair. During this process, vehicle-ground communication between the vehicle and the ground maintenance system enables data exchange and sharing, connecting the ground maintenance system data flow with the vehicle data and information flow.

[0028] Hereinafter, embodiments of the present disclosure will be described with reference to the accompanying drawings. However, it should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the present disclosure. In the detailed description below, for ease of explanation, many specific details are set forth to provide a comprehensive understanding of the embodiments of the present disclosure. However, it is apparent that one or more embodiments may also be implemented without these specific details. In addition, in the following description, descriptions of well-known structures and technologies are omitted to avoid unnecessary confusion of the concepts of the present disclosure.

[0029] The terms used herein are only for describing specific embodiments and are not intended to limit the present disclosure. The terms "comprise," "include," etc. used herein indicate the presence of the features, steps, operations, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, or components.

[0030] All terms used herein (including technical and scientific terms) have the meanings commonly understood by those skilled in the art unless otherwise defined. It should be noted that the terms used herein should be interpreted as having a meaning consistent with the context of this specification and should not be interpreted in an idealized or overly rigid manner.

[0031] When expressions such as "at least one of A, B, and C, etc." are used, they should generally be interpreted in accordance with the meaning commonly understood by those skilled in the art (for example, "a system having at least one of A, B, and C" should include but is not limited to a system having A alone, B alone, C alone, A and B, A and C, B and C, and / or A, B, C, etc.).

[0032] In the embodiments of this disclosure, the collection, updating, analysis, processing, use, transmission, provision, disclosure, and storage of all data involved (including, but not limited to, user personal information) comply with relevant laws and regulations, are used for legitimate purposes, and do not violate public order and good morals. In particular, necessary measures have been taken to prevent unauthorized access to user personal information data and to safeguard the security of user personal information, network security, and national security.

[0033] In the embodiments of the present disclosure, the user's authorization or consent is obtained before obtaining or collecting the user's personal information.

[0034] Under the traditional electromechanical system integration method, the vehicles, signals, power supply, sections and other disciplines are designed independently, information is isolated, and control is decentralized. In particular, the coordination efficiency between ground systems and vehicles is low, and it is difficult to achieve effective breakthroughs in improving the performance of the entire system.

[0035] In the current conventional urban rail ground maintenance system, the operator, section, and yard dispatchers each perform their own separate functions. When a vehicle malfunctions, the driver must communicate with the yard dispatcher via phone or fax to complete repair and dispatch. This manual dispatching method is inefficient. Furthermore, the vehicle maintenance data from each maintenance system is not interactive with operational data. For example, there is no data exchange between the overhaul system and the vehicle. This results in information silos between the maintenance systems and the vehicle. This leads to untimely feedback on maintenance status, significant site occupancy issues, and increasing maintenance costs year by year.

[0036] In recent years, some progress has been made in intelligent management and control systems for rail vehicle systems. For example, the DCC integrated management model has been explored for subways, and some subway depots have implemented intelligent management and control systems. Some train depots have also adopted automated assembly lines and logistics equipment for the maintenance of certain components, which has significantly improved the operational scheduling and management efficiency of rail vehicles. Therefore, to address the problems existing between vehicle fault maintenance systems and vehicles, it is necessary to propose a new intelligent management and control method to achieve timely feedback and repair of vehicle faults, thereby improving the efficiency of vehicle maintenance and repair.

[0037] In view of this, the embodiments of the present disclosure utilize an integrated vehicle-ground system to promptly obtain vehicle operating status information, initial fault diagnosis information, and ground maintenance operation status information. Based on this information, information about components to be repaired can be determined, and the time required for the vehicle to arrive at the ground maintenance site can be calculated. A vehicle maintenance scheduling strategy is generated based on the aforementioned information about components to be repaired, the time required to arrive at the ground maintenance site, and the ground maintenance operation status information. The vehicle is scheduled according to the scheduling strategy and awaits repair. During this process, vehicle-ground communication between the vehicle and the ground maintenance system enables data exchange and sharing, connecting the ground maintenance system data flow with the vehicle data and information flow. When a vehicle malfunctions, the vehicle operating status information and fault information can be promptly combined with ground maintenance records and ground maintenance operation status information to generate a reasonable vehicle scheduling and maintenance strategy. This at least partially addresses the issue of vehicle fault repair efficiency being impacted by untimely dispatch from the ground maintenance site, improves vehicle fault repair efficiency, shortens the waiting period for vehicle fault repair, and enables the repaired vehicle to promptly participate in vehicle operation scheduling, thus reducing the time cost of fault repair.

[0038] Figure 1 The schematic diagram of the vehicle-ground integrated system applicable to the vehicle maintenance scheduling method according to the embodiment of the present disclosure is shown schematically. It should be noted that, Figure 1 The examples shown are merely examples of system architectures to which the embodiments of the present disclosure may be applied, to help those skilled in the art understand the technical content of the present disclosure, but do not mean that the embodiments of the present disclosure may not be used in other devices, systems, environments or scenarios.

[0039] The above-mentioned vehicle-ground integrated system 100 that can be applied to the vehicle maintenance and scheduling method includes a vehicle-ground collaborative maintenance system. Specifically, it is mainly composed of a vehicle part and a ground part. The vehicle part mainly involves the TCMS, PHM subsystem of the vehicle system 140, and related traction and braking subsystems; the ground part mainly includes a signal system 130, a ground maintenance system 110, and a corresponding ground application service platform 120.

[0040] During vehicle operation, information such as the vehicle's mileage, PHM, and major fault information can be transmitted to the ground application service platform 120 in real time via the vehicle-to-ground communication channel. The signal system 130 superimposes the vehicle position information and forwards the vehicle operation status data on the line to the ground inspection and maintenance system 110 via the ground application service platform 120. At the same time, it obtains inspection and maintenance data in real time through the ground communication connection, and feeds back the inspection and maintenance data, fault handling data and other information to the vehicle system 140, so that each vehicle is managed in a specific file.

[0041] Compared with the traditional ground inspection and maintenance system, the ground inspection and maintenance system 110 involved in the present disclosure is newly equipped with an intelligent management and control platform 111 and an intelligent inspection and maintenance system 112, wherein the intelligent inspection and maintenance system includes an intelligent rack overhaul system 112-1.

[0042] The intelligent management and control platform 111 can compile vehicle maintenance scheduling and inbound and outbound plans based on vehicle operating status and fault diagnosis information, with planning and dispatching personnel combining data such as vehicle mileage. Vehicles are parked on appropriate tracks awaiting maintenance based on the return to depot and maintenance plans. Maintenance personnel collect work orders for fault repairs, and after taking into account the status of the equipment in the yard and collecting materials, they carry out the repairs. After the repairs are completed, the work order is submitted for feedback. Dispatchers schedule vehicle outbound travel based on the maintenance completion status and vehicle outbound travel plan, and simultaneously feed maintenance information back to the vehicle system 140 to complete the record of the train's maintenance status. Data mining and application analysis are performed on the fault data and maintenance data generated during the maintenance process, and fault data is connected to the vehicle system 140's PHM subsystem and the ground application service platform 120 to implement fault model maintenance guidance.

[0043] Figure 2 The following schematically shows the working principle of the intelligent management and control platform according to an embodiment of the present disclosure.

[0044] like Figure 2 As shown, the intelligent management and control platform includes intelligent management in DCC section yard dispatching operations, vehicle maintenance information management and control, section yard equipment asset status and evaluation, maintenance operation safety assurance and linkage, and maintenance data application analysis. The intelligent management module in DCC section yard dispatching operations sends the management plan to the vehicle maintenance information management and control module. The vehicle maintenance information management and control module and the section yard equipment asset status and evaluation module respectively send maintenance data and equipment data to the maintenance data application analysis module to realize intelligent management and control of ground maintenance. Operators perform related operations corresponding to the above modules. For example, maintenance team members and quality inspection operators interact with the vehicle maintenance information management and control module to realize work order collection and backfilling operations. The ground maintenance system communicates and exchanges data with the ground application service platform, ground signal system and vehicle system to realize vehicle-ground collaborative vehicle intelligent maintenance and dispatching management.

[0045] Taking intelligent overhaul system 112-1 as an example, the operation of the intelligent maintenance and inspection system is described. After intelligent overhaul system 112-1 obtains train mileage and fault diagnosis information, planning and dispatching personnel automatically arrange overhaul vehicles to appropriate maintenance tracks based on the compiled vehicle overhaul plan. Overhaul team maintenance personnel, based on the maintenance plan and work orders, are responsible for all maintenance steps, including vehicle disassembly and component disassembly, cleaning, assembly, testing, and final assembly and commissioning. Material management personnel, through material warehouse management, ensure timely material distribution. The overhaul information system provides dynamic maintenance process guidance and collects maintenance data during the maintenance process, creating an electronic component maintenance history. This maintenance information is then fed back to the vehicle system 140 to complete the train maintenance status record and update relevant key vehicle information, such as wheelset automatic correction information.

[0046] Figure 3 The following schematically shows the working principle of the intelligent rack overhaul system according to an embodiment of the present disclosure.

[0047] like Figure 3 As shown, the intelligent overhaul system includes information management and control of the overhaul process, automated maintenance of key vehicle components, and material warehousing management and distribution. The information management and control module of the overhaul process is used to issue maintenance process standards to the automated maintenance module of key vehicle components. The automated maintenance module of key vehicle components exchanges maintenance data with the information management and control module of the overhaul process. The material warehousing management and distribution module automatically distributes components to the automated maintenance module of key vehicle components. The user and the maintainer perform related operations corresponding to the above modules. For example, the warehouse logistics management personnel perform material management and matching operations, and coordinate with the material warehousing management and distribution. The ground inspection and maintenance system communicates and exchanges data with the ground application service platform, the ground signal system and the vehicle system to realize vehicle-ground collaborative intelligent inspection, maintenance and scheduling management.

[0048] It should be understood that Figures 1 to 3 The number of system modules and the connection relationship between them are only for illustration purposes. Depending on the implementation requirements, there may be any number and function of system modules.

[0049] Figure 4 A flowchart of a vehicle maintenance scheduling method based on a vehicle-body integrated system according to an embodiment of the present disclosure is schematically shown.

[0050] like Figure 4 As shown, the method 400 includes operations S410 to S450.

[0051] In operation S410 , operating status information, initial fault diagnosis information, and ground maintenance operation status information of a plurality of vehicles are acquired.

[0052] In operation S420 , the historical mileage of each vehicle and the initial fault diagnosis information of each vehicle are analyzed to determine information of each component to be repaired.

[0053] In operation S430 , the driving time required for each vehicle to reach the ground inspection and maintenance site is calculated based on the running position and running speed of each vehicle.

[0054] In operation S440 , maintenance scheduling strategy information for a plurality of vehicles is generated based on information of each component to be maintained, each driving time, and ground maintenance operation status information.

[0055] In operation S450, based on the maintenance scheduling strategy information, each vehicle is scheduled to enter a ground maintenance site according to its corresponding track information to wait for maintenance.

[0056] According to embodiments of the present disclosure, operating status information includes the vehicle's operating position, operating speed, and historical mileage. The historical mileage can reflect the cause of a vehicle failure and the service life of its components. Initial fault diagnosis information, including the faulty vehicle number and fault location, is used to identify the initial scope of the vehicle failure. For example, initial fault diagnosis information might read: "Train X1025's traction motor is faulty and unable to traction operate normally." Operating status information and initial fault diagnosis information can be obtained through communication with the vehicle system.

[0057] The ground maintenance operation status information indicates the specific situation of the ground maintenance and can be obtained through various ground subsystems.

[0058] According to embodiments of the present disclosure, the component to be repaired can be any malfunctioning vehicle component, such as a traction motor, a temperature sensor, a speed sensor, a bogie, a key vehicle body component, a bearing, and the like, without limitation. Information about the component to be repaired includes information such as the vehicle number to which the component belongs, the name and model of the component to be repaired, the cause of the malfunction, and a repair and maintenance plan for the component.

[0059] Based on the vehicle's historical mileage and initial fault diagnosis information, the information of the parts to be repaired can be determined. For example, based on the information "the mileage of the X1025 vehicle has reached 1.7 million kilometers, the traction motor bearing is faulty, and the traction operation has failed", the vehicle's mileage meets the overhaul plan and the traction motor bearing needs to be replaced. Therefore, the information of the parts to be repaired can be determined as "the traction motor bearing P1213 of the X1025 vehicle is severely worn and needs to be overhauled and the bearing replaced".

[0060] According to an embodiment of the present disclosure, after determining the information of the parts to be repaired, the location of the ground repair and maintenance site that the vehicle needs to enter can be determined according to the repair and maintenance plan, and the driving time required for the vehicle to reach the designated ground repair and maintenance site can be calculated based on the vehicle's operating position and operating speed.

[0061] Based on information about the components to be repaired, travel time, and ground maintenance operation status, a maintenance scheduling strategy tailored to the vehicle's specific situation is generated. This maintenance scheduling strategy specifies the track information the vehicle will be on while awaiting repair at the ground maintenance site, including track number and location. The maintenance scheduling strategy also indicates the time the vehicle will enter the designated track awaiting repair. Based on this maintenance scheduling strategy, the vehicle is dispatched to the ground maintenance site according to the corresponding track information to await repair.

[0062] According to the embodiments of the present disclosure, the vehicle's operating status information, initial fault diagnosis information and ground maintenance operation status information are obtained in a timely manner through the vehicle-ground integrated system. Based on the above information, the information of the parts to be repaired can be determined, and the time required for the vehicle to arrive at the ground maintenance site can be calculated. Based on the above information of the parts to be repaired, the time required to arrive at the ground maintenance site, and the ground maintenance operation status information, a vehicle maintenance scheduling strategy is generated. The vehicle is scheduled to operate according to the above scheduling strategy and wait for maintenance. In this process, the vehicle and the ground maintenance system communicate with each other for data exchange and sharing, opening up the ground maintenance system data and vehicle data flow and information flow. When a vehicle breaks down, it can timely combine the vehicle's operating status information, fault information with the ground maintenance record information and the ground maintenance operation status information to generate a reasonable vehicle scheduling and maintenance strategy, thereby achieving the accuracy of vehicle maintenance and repair, improving the efficiency of vehicle fault repair, and reducing maintenance costs.

[0063] According to an embodiment of the present disclosure, maintenance scheduling strategy information for multiple vehicles is generated based on information on each component to be repaired, each driving time and ground maintenance operation status information, including: determining each waiting time and each maintenance time based on information on each component to be repaired and ground maintenance operation status information; wherein each waiting time represents the time required for each vehicle to wait for maintenance; each maintenance time represents the time required for repairing each vehicle; and generating maintenance scheduling strategy information based on each waiting time, each maintenance time and each driving time.

[0064] The duration of the entire vehicle maintenance process includes the time it takes for the vehicle to travel from its current location to the ground maintenance site, the time it takes to wait for maintenance, and the time required for the maintenance process. Therefore, it is necessary to comprehensively consider the waiting time, maintenance time, and driving time to formulate a reasonable maintenance scheduling strategy.

[0065] Figure 5AThe following schematically illustrates a process diagram for generating a vehicle maintenance scheduling strategy according to an embodiment of the present disclosure.

[0066] like Figure 5A As shown, based on the ground maintenance operation status information 541 and the information of the parts to be repaired 542, the waiting time 543 and the maintenance time 544 can be determined, and combined with the driving time 545 of the vehicle from the current position to the ground maintenance site, a maintenance scheduling strategy 546 is generated.

[0067] For example, based on the ground maintenance operation status information and the information of the parts to be repaired, it is determined that the waiting time is 2 days, the maintenance time is 7 days, and the driving time from the current location to the ground maintenance site is 5 hours, thereby generating a maintenance scheduling strategy.

[0068] According to the embodiments of the present disclosure, waiting time and maintenance time can be determined based on information about the components to be repaired and the status of ground maintenance operations. Combined with actual real-world applications, a maintenance scheduling strategy is generated by comprehensively considering the waiting time, maintenance time, and driving time of vehicles. This makes the scheduling strategy more reasonable, efficient, and in line with actual conditions, facilitating smooth vehicle maintenance scheduling, preventing prolonged maintenance track occupancy, and improving maintenance efficiency.

[0069] According to an embodiment of the present disclosure, each waiting time and each maintenance time is determined based on the information of each component to be repaired and the ground maintenance operation status information, including: obtaining the spare parts inventory information, historical procurement information and historical maintenance information of the ground maintenance site; generating the procurement time of each component to be repaired based on the spare parts inventory information, the information of each component to be repaired and the historical procurement information; obtaining the expected maintenance time of the waiting vehicles on each track from the ground maintenance operation status information; generating each waiting time based on the expected maintenance time of the waiting vehicles on each track and the procurement time of each component to be repaired; and generating each maintenance time based on the information of each component to be repaired and the historical maintenance information.

[0070] According to the embodiments of the present disclosure, the inventory and procurement status of spare parts determine the time required for spare parts procurement, which in turn affects the waiting time. In addition, the operating status of ground maintenance also affects the waiting time.

[0071] Figure 5B The following schematically shows a process diagram for generating the vehicle maintenance waiting time according to an embodiment of the present disclosure.

[0072] like Figure 5BAs shown, waiting time 543 can be determined by purchasing time 543-1 and estimated maintenance time 543-2 of the component to be repaired. Purchasing time 543-1 of the component to be repaired is determined by spare parts inventory information 543-11, historical purchasing information 543-12, and component to be repaired information 542. Estimated maintenance time 543-2 can be estimated based on ground maintenance operation status information 541.

[0073] Spare parts inventory information 543-11 includes the number of spare parts in stock and their storage locations. Historical procurement information 543-12 includes the historical procurement time required for the repaired parts. Spare parts inventory information and historical procurement information can be obtained through communication between the various ground maintenance subsystems. When estimating waiting time, the availability of spare parts may be affected if the repaired part requires replacement.

[0074] For example, the part to be repaired is the traction motor P1546, which requires replacement for 5 units. The spare parts inventory information for the same model of traction motor is "Traction motor P1546 in stock, 20 units available." This satisfies the replacement requirement. The material management staff only needs to retrieve the required number of parts from the warehouse and deliver them. The estimated procurement time for the part to be repaired is 3 hours. If the spare parts inventory information for the same model of traction motor is "Traction motor P1546 in stock, 0 units available," which does not meet the replacement requirement, the part needs to be re-purchased. Based on the historical procurement information, "Traction motor P1546 ordered on October 5, 2023, received on October 12, 2023, with a procurement time of 7 days," the procurement time for the part to be repaired is estimated to be 7 days.

[0075] The ground maintenance operation status information 541 includes the personnel status during the ground maintenance operation, the ground maintenance track occupancy status, the maintenance operation progress status information, etc. Based on the ground maintenance operation status information, the estimated maintenance time 543-2 can be determined. The estimated maintenance time indicates the time required to maintain the vehicle undergoing ground maintenance operation.

[0076] For example, all three maintenance tracks are currently in operation, with progress at 5%, 60%, and 85%, respectively, and maintenance personnel are working. Analysis of the maintenance status indicates that the time required for vehicles on the three tracks to complete the current maintenance work is 7 days, 3 days, and 1 day. Taking the minimum of these three values, the estimated maintenance time is 1 day. If any of the maintenance tracks is currently idle, the estimated maintenance time is 0 days.

[0077] According to the embodiments of the present disclosure, the procurement time for the repaired parts can be determined based on acquired spare parts inventory information, historical procurement information, and information about the parts to be repaired. The estimated repair time can be determined based on ground maintenance operation status information. The waiting time for vehicle repairs can be determined based on the procurement time and the estimated repair time. Comprehensive consideration of the possible factors affecting the waiting time makes the waiting time estimate more accurate, and the resulting maintenance scheduling strategy is more comprehensive and reasonable, thereby improving maintenance efficiency.

[0078] According to an embodiment of the present disclosure, each maintenance duration is generated based on the information of each component to be repaired and the historical maintenance information, including: for each component to be repaired, extracting the vehicle model information on which the component to be repaired has been assembled from the information of the component to be repaired; determining at least one historical maintenance duration corresponding to the vehicle model information and the information of the component to be repaired from the historical maintenance information; and calculating the maintenance duration based on the at least one historical maintenance duration.

[0079] According to an embodiment of the present disclosure, determining at least one historical maintenance duration corresponding to vehicle model information and component information to be repaired from historical maintenance information includes historical maintenance durations corresponding to both the same vehicle model information and the same component information to be repaired; also includes historical maintenance durations corresponding to the same vehicle model information and the same type of component information to be repaired; also includes historical maintenance durations corresponding to the same type of vehicle model information and the same component information to be repaired; and also includes historical maintenance durations corresponding to the same type of vehicle model information and the same type of component information to be repaired. The historical maintenance information may contain historical maintenance information that completely matches the component information to be repaired and the vehicle model information, but it may also be impossible to find completely matching historical maintenance information. In this case, the maintenance duration can be determined based on the same type of components and models.

[0080] In particular, when multiple historical maintenance durations are obtained based on historical maintenance information, the maintenance duration can be calculated by weighted summing or calculating the average of the historical maintenance durations.

[0081] According to the embodiments of the present disclosure, based on the information of the component to be repaired and the vehicle model information corresponding to the component to be repaired, the corresponding historical maintenance duration is determined from historical maintenance information, and the maintenance duration of the component to be repaired is then estimated to generate a maintenance scheduling strategy. Because the maintenance scheduling strategy takes into account actual maintenance conditions, the resulting maintenance scheduling strategy is more closely aligned with actual application scenarios, improving the rationality of the maintenance scheduling strategy.

[0082] According to an embodiment of the present disclosure, the above method further includes: determining candidate tracks corresponding to information of each component to be repaired; and determining a target track from the candidate tracks based on operation status information on each candidate track.

[0083] Maintenance tracks include designated maintenance tracks for specific components and general maintenance tracks. For example, maintenance track x is only used for sensor replacement, while maintenance track y can be used for frame overhaul, that is, it can be used for all maintenance links such as vehicle disassembly and component disassembly, cleaning, assembly, testing, and vehicle final assembly and commissioning. Therefore, it is necessary to determine the candidate tracks based on the condition of the components to be repaired.

[0084] Based on the operating status information of candidate tracks, the target track is determined from each candidate track to avoid long maintenance wait times and track occupancy conflicts. For example, if the operating status of candidate track A is Idle, it can be determined as the target track. If the operating status of candidate track A is Operating, other candidate tracks can be determined as the target track.

[0085] According to the embodiments of the present disclosure, candidate tracks are selected based on the condition of the components to be repaired, enabling targeted and operational repairs. Determining the target track based on the operational status of the candidate tracks can reduce waiting times for repairs, avoid serious track occupancy, and improve repair efficiency.

[0086] According to an embodiment of the present disclosure, based on the maintenance scheduling strategy information, each vehicle is scheduled to enter the ground maintenance and repair site according to its corresponding track information to wait for maintenance, including: determining the track information for each vehicle to enter its corresponding track and the time information of each vehicle arriving at the ground maintenance site based on the maintenance scheduling strategy information; sending the time information of each vehicle arriving at the ground maintenance site and the track information for each vehicle to enter its corresponding track to each vehicle, so that each vehicle can generate a vehicle operation control strategy based on the time information, track information and operation status information of each vehicle to control each vehicle to enter the ground maintenance and repair site according to its corresponding track information to wait for maintenance.

[0087] According to embodiments of the present disclosure, the time each vehicle arrives at a ground maintenance site can be determined based on the aforementioned travel time. After obtaining the time of arrival at the ground maintenance site and the track information it enters, the vehicle's operation scheduling strategy can be determined based on this information, including when and where the vehicle departs, at what speed, and when and where it arrives at the designated maintenance track after traveling a target distance.

[0088] According to an embodiment of the present disclosure, the ground inspection and maintenance system generates a corresponding vehicle inspection and maintenance scheduling strategy based on information obtained from the vehicle system and the ground inspection and maintenance subsystem, and sends specific instructions of the vehicle inspection and maintenance scheduling strategy to the vehicle system to schedule vehicle operation.

[0089] The historical mileage of each vehicle and the initial fault diagnosis information of each vehicle are analyzed to determine the information of each component to be repaired. The following describes the process of determining the component to be repaired by taking the fault occurring in the vehicle traction system as an example.

[0090] Figure 6 An example judgment flowchart for determining a component to be repaired according to an embodiment of the present disclosure is schematically shown.

[0091] like Figure 6 As shown, the process 600 includes operations S621 to S625.

[0092] In operation S621 , the historical running mileage of each vehicle and the initial fault diagnosis information of each vehicle are analyzed.

[0093] In operation S622 , it is determined whether the historical running mileage of each vehicle is greater than a predetermined threshold. If the determination result is yes, operation S623 is executed; if the determination result is no, operation S624 is executed.

[0094] In operation S623 , it is determined that the component to be repaired is a traction motor bearing.

[0095] In operation S624 , it is determined whether the initial fault information is that the traction motor is grounded. If the determination result is yes, operation S625 is executed.

[0096] In operation S625 , it is determined that the component to be repaired is a traction motor.

[0097] For example, if vehicle X1235 has a historical mileage of 1.65 million kilometers, which is greater than the predetermined threshold of 1.5 million kilometers, the component to be repaired can be determined to be the traction motor bearing. If vehicle X1248 has a historical mileage of 1 million kilometers, which is less than the predetermined threshold of 1.5 million kilometers, and the initial fault information for this vehicle is a traction motor ground fault, the component to be repaired can be determined to be the traction motor.

[0098] According to the embodiments of the present disclosure, the condition of the components to be repaired can be accurately and quickly determined based on the vehicle's mileage and the vehicle's initial fault diagnosis information, so as to facilitate efficient subsequent vehicle repairs.
