[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] To make the objectives, technical solutions and advantages of the present invention more clear, embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0028] In a first aspect, an embodiment of the present invention provides a method for managing a railway port digital freight yard system fault.

[0029] In one embodiment, referring to Figure 1 , Figure 1 This is a flow chart of an embodiment of the method for managing a fault in a digital freight yard system at a railway port according to the present invention. Figure 1 As shown, the fault management method of the railway port digital freight yard system includes:

[0030] Step S10, obtaining the corresponding relationship between each business operation and the status of each subsystem of the railway port digital freight yard system;

[0031] In this embodiment, the railway port digital freight yard system is the railway port digital freight yard dispatching and control integrated system, which will be used hereinafter. By managing the asset information of the railway port digital freight yard dispatching and control integrated system indoors, the production date, manufacturer, production date, name, model, service life, purchase contract number, and registrant information of the railway port digital freight yard dispatching and control integrated system and its maintainable units are recorded, facilitating the establishment and maintenance of the railway port digital freight yard dispatching and control integrated system ledger.

[0032] Specifically, the operational status of in-use equipment in the railway port digital freight yard system is monitored at four levels: the freight yard, the machine room, the cabinet, and the board. 3D visual technology is used within the machine room to intuitively display the operational status of on-site equipment. This interface provides asset information, physical location information, and operational status information for maintainable units, enabling maintenance personnel to gain timely access to comprehensive equipment operational information and quickly locate boards.

[0033] Reference Figure 2 , Figure 2 Schematic diagram of the corresponding relationship between the business operations of the present invention and the status of each subsystem of the railway port digital freight yard system. Figure 2 As shown, the business operation information of spare parts and the railway port digital freight yard system is managed, and the business operation types run through the entire life cycle of the equipment. Business operations include: the warehousing, out-warehouse, shelving, de-shelving, loaning, returning, overhauling, repairing, reporting, sending for repair, and scrapping of spare parts of the railway port digital freight yard system, as well as the shelving, de-shelving, damage, repair, and repairing of on-track components of the railway port digital freight yard system. The status of each subsystem of the railway port digital freight yard system includes: fault status, in-use status, pending repair status, inventory status, scrapped status, repair status, loan status, and under-maintenance status. Each equipment status has its corresponding business operation, where there is a one-to-many correspondence between equipment status and business operations. For example, the business operations corresponding to the fault state include removal from shelves and repair; the business operations corresponding to the in-use state include damage, putting on shelves and taking off shelves; the business operations corresponding to the pending repair state include scrapping and sending for repair; the business operations corresponding to the inventory state include reporting for repair, returning, overhauling, outbound, inbound and putting on shelves; the business operations corresponding to the repaired state include scrapping and repairing; the business operations corresponding to the loaned state include returning; and the business operations corresponding to the under-repair state include scrapping and repairing.

[0034] Among them, the "in-use equipment" of the railway port digital freight yard system refers to subsystems that are already in operation, including the container management subsystem, digital twin subsystem, level crossing automatic control subsystem, electronic red card subsystem, train pick-up and delivery gate automatic opening and closing subsystem, reach stacker positioning and container number collection subsystem, gantry crane positioning and container number collection subsystem, container forklift positioning and container number collection subsystem, IGV guided vehicle dispatching and control subsystem, switch equipment, red card equipment, and road crossing signal equipment. Spare parts refer to spare parts prepared in accordance with relevant rules and standards for the above subsystems or equipment, corresponding to 2% of the total number of boards and 2% of the total number of equipment in the system. This ensures that spare parts are available nearby for timely replacement or replacement of boards or equipment when troubleshooting. The above content includes unified management and information entry of production date, manufacturer, production time, name, model, service life, purchase contract number, registrant information, supplier technical support, QR code, etc.

[0035] Step S20: constructing a railway port digital freight yard system operation and maintenance scheduling model based on the set model assumptions and set model constraints;

[0036] In this example, the total maintenance time for equipment is minimized given limited maintenance personnel and spare parts resources. Due to the varying distances between the freight yard and the dispatch center, the maintenance sequence determines the overall maintenance time and the waiting time for each piece of equipment. Furthermore, due to varying levels of equipment failure, each piece of equipment is assigned a different weight. The goal of the railway port digital freight yard system's operation and maintenance scheduling model is to minimize the total equipment maintenance time and the preparation time for maintenance personnel.

[0037] The model assumptions for the equipment operation and maintenance scheduling model for the railway port digital freight yard system include: a) maintenance personnel have fixed maintenance times for specific equipment; b) each piece of equipment is maintained by only one maintenance personnel at a time; and c) each piece of equipment cannot fail multiple times within a preset timeframe. Furthermore, the model constraints for the railway port digital freight yard system operation and maintenance scheduling model include: a) a maintenance personnel can only maintain one piece of equipment at a time; b) each piece of equipment is maintained by only one maintenance personnel; and c) the number of spare parts in use is less than the number in reserve.

[0038] Specifically, the various subsystems of the railway port digital freight yard dispatching and control integration system include container management subsystem, digital twin subsystem, level crossing automatic control subsystem, electronic red card subsystem, train pick-up and delivery car door automatic opening and closing subsystem, front loader positioning and box number collection subsystem, gantry crane positioning and box number collection subsystem, container forklift positioning and box number collection subsystem, IGV guided vehicle dispatching and control subsystem, switch equipment, red card equipment and road crossing signal equipment. Taking each freight yard as a unit, the freight yard has the above subsystems and equipment. The 10 equipment and 1 subsystem in the freight yard are guaranteed and undertaken by one maintenance personnel, and the maintenance personnel of the freight yard are allocated to all subsystems and equipment one by one according to the number of people, and an exhaustive model is established, that is, 1 Maintenance personnel are responsible for the equipment in the freight yard and a certain digital freight yard subsystem. All subsystems and equipment in a freight yard will be completed by N maintenance personnel. In the actual fault handling process, one or multiple faults may occur. When multiple faults occur, one maintenance personnel cannot complete the fault handling and needs to dispatch the No. 2 maintenance personnel in the adjacent nearest area to assist. According to the fault prompt and work order display, by coordinating the processing time, maintenance personnel workload and current work status, maintenance personnel in other areas are dispatched to assist. At this time, if a fault occurs in an adjacent area, the maintenance personnel in the boundary area of the adjacent area will be dispatched to assist in handling the fault in that area. This exhaustive model is the operation and maintenance scheduling model of the integrated scheduling and control system of the railway port digital freight yard.

[0039] Step S30: determining a fault management strategy for the railway port digital freight yard system based on the corresponding relationship and the operation and maintenance scheduling model.

[0040] In some specific embodiments, step S30 includes:

[0041] The operation and maintenance scheduling model is solved by a tabu search algorithm to obtain a maintenance personnel scheduling decision plan;

[0042] A fault management strategy for the railway port digital freight yard system is determined based on the corresponding relationship and the maintenance personnel scheduling decision plan.

[0043] In this embodiment, Figure 3As shown in the figure, the P1 area mainly includes a container management subsystem and subsystems of the railway port digital freight yard dispatching and control integration system numbered 1-5 (one electronic red card derailer switch, one level crossing automatic control column machine, one highway signal machine, and two reach stacker positioning and container number collection terminals). The P2 area mainly includes a digital twin security subsystem and subsystems of the railway port digital freight yard dispatching and control integration system numbered 6-8 (one gantry crane positioning and container number collection terminal, one container forklift positioning and container number collection terminal, and one set of automatic opening and closing device for train pick-up and delivery doors). At this time, if an equipment failure occurs at the five-pointed star position at the intersection of P1 and P2, the maintenance personnel at the subsystem numbered 1, 5, 6 or 8 will handle it nearby in accordance with the principle of the nearest maintenance personnel being responsible for the equipment. The fault handling at this location is completed by two maintenance personnel, that is, the maintenance personnel numbered 1 or 5 in the P1 area and the maintenance personnel numbered 6 or 8 in the P2 area perform maintenance. If a fault occurs at another location in the P1 area, the corresponding maintenance personnel in the P3 area adjacent to P1 will assist in handling it. During the handling process, if the P1 and P2 boundary handling personnel complete their work ahead of time, they will rush to the junction of the P1 and P3 areas to handle the fault. The main purpose of the operation and maintenance scheduling model of the integrated scheduling and control system for the digital freight yard of the railway port is to ensure that there are personnel to handle each fault, the handling time of each fault is the shortest, and the handling personnel of each fault are dispatched nearby to reach the fault location point as quickly as possible.

[0044] Because the operation and maintenance scheduling problem of the integrated dispatching and control system for digital freight yards at railway ports is similar to the vehicle routing problem, a similar solution method to vehicle routing is considered for solving the operation and maintenance scheduling model. The vehicle routing problem has been proven to be NP-hard, and therefore the operation and maintenance scheduling problem is also NP-hard, with the complexity of the solution increasing exponentially with the problem size. NP-hard problems are those that cannot be solved efficiently in polynomial time, but whose solutions can be verified in polynomial time.

[0045] The operation and maintenance scheduling model is solved using the tabu search algorithm. As a metaheuristic algorithm, the tabu search algorithm is an extension of local domain search. Tabu search involves concepts such as neighborhood, tabulist, tabu length, candidate solution, and aspiration criterion.

[0046] The solution form of the operation and maintenance scheduling model of the integrated scheduling and control system of the digital freight yard at the railway port is as follows:

[0047] The length of the solution to the operation and maintenance scheduling model is equal to the number of faulty devices + the number of maintenance personnel + 1. The interval between two zeros represents a faulty device repaired by a maintenance personnel. The neighborhood of the current solution refers to the set of solutions adjacent to the current solution. Neighborhood solutions can be obtained by performing a one-step transformation on the current solution, such as randomly swapping two (or several) digits in the solution or reversing a segment of the digit sequence. The taboo process algorithm used in the operation and maintenance scheduling model is as follows:

[0048] Step 1: Initialize the taboo table and the current solution, and set the current solution to be equal to the optimal solution;

[0049] Step 2: Select N1 best neighbors from the N neighbors of the current solution;

[0050] Step 3: Check whether the N1 best neighbors are all in the tabu list. If they are, go to step 5; otherwise, go to step 4.

[0051] Step 4: Set the current solution equal to the best neighbor that is not tabooed and update the taboo table;

[0052] Step 5: Check whether the current solution is better than the optimal solution. If so, the optimal solution is equal to the current solution.

[0053] Step 6: Check whether the number of times the optimal solution has not been updated reaches the maximum value M. If it reaches the maximum value M, the algorithm ends, otherwise go to step 2.

[0054] The operation and maintenance scheduling model is solved using the tabu search algorithm. The solution to the operation and maintenance scheduling model provides a personnel scheduling decision plan, namely, "when and by whom to maintain and repair which equipment", which provides a reference for management personnel's decision-making. The maintenance personnel scheduling decision plan is shown in Table 1.

[0055] Table 1

[0056] Maintenance personnel Device 1 Device 2 Device 3 … Device n Maintenance Personnel 1 1:00-2:00 * * … 5:00-6:00 Maintenance Personnel 2 * 2:00-3:00 * … *

[0057] As can be seen from Table 1, maintenance personnel 1 needs to perform maintenance on equipment 1 from 1:00 to 2:00 and on equipment n from 5:00 to 6:00; maintenance personnel 2 needs to perform maintenance on equipment 2 from 2:00 to 3:00.

[0058] To monitor maintenance operations, the railway port digital freight yard dispatching and control integrated system displays maintenance personnel's location information on its user interface. This information is obtained by the maintenance personnel's terminal device using mobile network or Wi-Fi communication. The location is determined based on Beidou, carrier base stations, and Wi-Fi, and then transmitted to a web server.

[0059] Currently, positioning technologies are mainly divided into three categories: Beidou-based positioning, mobile network-based positioning, and hybrid positioning. Beidou positioning offers high accuracy but is demanding on the environment; it may not be able to cover obstacles. Mobile network-based positioning, on the other hand, has relatively loose environmental requirements but offers lower accuracy. Taking into account practical considerations, this embodiment utilizes Beidou RTK + mobile network hybrid positioning technology to improve positioning accuracy while ensuring successful positioning. Furthermore, it stores personnel location information and supports playback of personnel's historical routes.

[0060] The correspondence between each business operation and the status of each subsystem of the railway port digital freight yard system is sent to the terminal equipment of the maintenance personnel, so that the maintenance personnel can timely and comprehensively understand the operation information of each subsystem of the railway port digital freight yard system through the terminal equipment. Combined with the personnel scheduling decision-making plan, each subsystem is monitored and maintained in an all-round way, which greatly improves the maintenance personnel's fault management efficiency during the operation of each subsystem of the railway port digital freight yard system.

[0061] In this application, through the above steps, a comprehensive monitoring subsystem of the railway port digital freight yard dispatching and control integrated system is obtained, such as Figure 4 As shown, the comprehensive monitoring subsystem includes the railway port digital freight yard system monitoring subsystem and the maintenance and repair process management subsystem. The comprehensive monitoring subsystem covers the freight yard, the freight yard workshop, and the freight yard work team. It encompasses all railway port digital freight yard systems and serves as an office support system for general maintenance personnel, reminding and urging them to complete maintenance tasks promptly. As a decision-making support system for managers, it provides visual management of all equipment and spare parts, providing query statistics on equipment, faults, and repair tasks. It also allows for the timely issuance of process and fault work orders to relevant maintenance personnel, shortening repair time for faulty equipment and improving the completion rate of repair tasks.

[0062] The comprehensive monitoring subsystem adopts a B / S structure (browser / server structure), which can support 100 users to access and operate simultaneously and manage 500 railway port digital freight yard systems.
