[0036] The method embodiments provided in the embodiments of the present application can be executed in a mobile terminal, a computer terminal or a similar computing device. Taking running on a mobile terminal as an example, Figure 1 1 is a hardware structure block diagram of a mobile terminal of a display method for electric wheel maintenance of a mining truck according to an embodiment of the present invention. Figure 1 As shown, the mobile terminal may include one or more ( Figure 1 Only one is shown in the figure) a processor 102 (the processor 102 may include but is not limited to a processing device such as a microprocessor MCU or a programmable logic device FPGA) and a memory 104 for storing data, wherein the mobile terminal may also include a transmission device 106 and an input / output device 108 for communication functions.

[0038] In this embodiment, a display method for electric wheel maintenance of a mining truck running on a mobile terminal, a computer terminal or a similar computing device is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0039] Figure 2 FIG. 1 is a flow chart of a method for displaying the maintenance of an electric wheel of a mining truck according to an embodiment of the present application. Figure 2 As shown, the method comprises the following steps:

[0040] Step S201, obtaining basic information, wherein the basic information includes one or more of user-related information, production line workstation information, and process parameter information, wherein the user-related information is information about personal information and authority configuration related to the user, the production line workstation information is information about work positions and areas in the production line, and the process parameter information is information about equipment operation during production and maintenance;

[0041] Specifically, user-related information includes the personal information of operators and managers, such as work number, name, contact information, etc. More importantly, it includes their permission configuration information. Permission configuration ensures that each user can only access and operate the relevant data and functions within their scope of responsibility, which is crucial to maintaining the security of the system and the standardization of operations.

[0042] Production line workstation information refers to the detailed data of each work position and area on the production line, including the workstation code, name, function description, location on the production line, etc.

[0043] Process parameter information is the key data for equipment operation during production or maintenance, including the set process flow, parameter settings (such as temperature, pressure, torque, etc.), equipment status, and possible process change records.

[0044] Step S202, using the MES system to store the above basic information;

[0045] Specifically, MES (Manufacturing Execution System) is the core of the digital maintenance system, which is responsible for storing, managing and processing real-time data of all workstations on the production line. After obtaining the basic information in step S201, the MES system stores this information in the database and builds a comprehensive basic data platform. Through the storage function of the MES system, enterprises can establish a complete information library, including user permissions, the layout and functions of production line workstations, the settings of process parameters and historical records, etc. These data are crucial for production scheduling, quality control, resource management and other aspects.

[0046] Step S203, when receiving a retrieval request, retrieve the basic information from the MES system and display the basic information in a display interface, wherein the retrieval request is a request for retrieving data.

[0047] Specifically, when users (such as operators, workshop managers, or system administrators) need to view or use this basic information, they can initiate a retrieval request through the interface. After receiving the request, the MES system will retrieve and extract the required basic information from the stored database, and then present this information to the display interface for users to view and operate. For example, an operator can retrieve the process parameters related to the current workstation through the industrial computer at the workstation, or a manager can retrieve the workstation layout and status of the entire production line for production scheduling or resource allocation.

[0048] Through this embodiment, information is uploaded to the MES system as a digital signal. The MES system supports data query and traceability, so that data can be saved through the MES system and retrieved through the MES system when needed, reducing dependence on paper records and facilitating the storage and retrieval of electric wheel information.

[0049] Specifically, this solution involves providing a digital maintenance solution based on electric wheels of large-tonnage mining trucks, including a maintenance MES system based on realizing digital management of the electric wheel maintenance system and analyzing and processing the data obtained from the inspection, as well as a set of maintenance process parameter information, personnel information, dimensional measurement, and flaw detection results and other data that can be traced in real time to achieve full-process maintenance quality control. Digital maintenance work step guidance operation system for electric wheels.

[0050] In the existing scheme, all maintenance is done manually, with heavy workload, low efficiency and high work intensity. At present, intelligent technology has become the world-recognized core technology for improving the overall competitiveness of the manufacturing industry. Digital mines have put forward higher requirements for the intelligence, high-end, customization and reliability of maintenance workshops. Based on this, the maintenance process of electric wheels of large-tonnage mining trucks is studied to realize the intelligent transformation of the maintenance process and improve the overall intelligence level of mines. The disassembly of electric wheels requires the disassembly and assembly of a large number of bolts of various specifications, among which the disassembly torque of large-size bolts reaches 6500Nm. The maintenance information such as bolt torque data and dimensional measurement data are recorded on paper, which is not convenient for storage and retrieval. It is urgent to introduce a digital system to achieve quality traceability and strengthen maintenance quality control. At present, large wrenches are used for manual disassembly, and the handheld tools weigh up to 10 kilograms, with low operating efficiency and high labor intensity. The disassembly and assembly parts of various types of electric wheels are large in size and weight, and cannot be carried by manpower. At present, the operation of overhead cranes and semi-gantry cranes is manually controlled, and the operation efficiency is low. In addition, there are certain safety hazards when people and equipment cross during operation. The key disassembled parts need to be inspected for size and defects. Currently, this is only done through manual visual observation and empirical judgment. Manual measurement is difficult, has low accuracy, and lacks theoretical basis and data support.

[0051] The existing maintenance platform is unable to digitally record and hierarchically manage maintenance data, production scheduling, execution, process quality management and product traceability of maintenance work to meet the needs of information-based manufacturing execution of each module. Develop a digital maintenance MES platform and a digital maintenance MES system for electric wheels. The MES system is located at the production data management and manufacturing execution level to realize the functions of production scheduling, execution, process quality management and product traceability of maintenance work, visualize the maintenance process data information, help enterprises formulate reasonable maintenance plans, and improve product maintenance quality. It provides a solid data foundation and scientific basis for improving the production management level of enterprises, saving production costs, and enhancing the market competitiveness of enterprises.

[0052] Specifically, the main functions of this solution include basic information management, process management, maintenance scheduling management, maintenance execution management, material management, quality management, maintenance resource management, exception management, kanban management, AGV equipment management, vertical warehouse equipment management, automatic flip equipment management, automatic bolt removal equipment management, flaw detection equipment management, three-coordinate detection equipment management, and auxiliary equipment management.

[0053] Specifically, a digital maintenance MES system for electric wheels of large-tonnage mining trucks can be developed. The MES system includes: realizing digital management of the electric wheel maintenance system, analyzing and processing the data obtained from the detection, realizing digital remote office, and intuitively presenting the maintenance process information in the form of charts; and based on the maintenance process parameter information, personnel information, dimensional measurement and flaw detection results and other data, real-time traceability can be achieved to realize the whole process control of maintenance quality.

[0054] Specifically, this solution can realize the digital management of the electric wheel maintenance system, analyze and process the data obtained from the inspection, realize digital remote office, and intuitively present the maintenance process information in the form of charts; and based on the maintenance process parameter information, personnel information, dimensional measurement and flaw detection results and other data, real-time traceability can be achieved to realize the whole process control of maintenance quality.

[0055] Based on the digital maintenance MES system platform of large-tonnage mining truck electric wheels, the main technical architecture is as follows: Figure 3 As shown, it integrates some existing independent information systems: basic information management, process management, maintenance scheduling management, maintenance execution management, material management, quality management, maintenance resource management, exception management, and kanban management. The control module mainly includes: AGV equipment management, vertical warehouse equipment management, automatic flip equipment management, automatic bolt removal equipment management, flaw detection equipment management, three-coordinate detection equipment management, and auxiliary equipment management.

[0056] Specifically, based on the digital maintenance MES system platform for large-tonnage mining truck electric wheels, the overall logical architecture is as follows: Figure 4 As shown in the figure, the digital maintenance MES platform and the electric wheel digital maintenance MES system are located at the production data management and manufacturing execution level. They mainly perform functions such as production scheduling, execution, process quality management and product traceability of maintenance work. They synchronize data with cMES, PLM, ERP and card adjustment systems upstream, and undertake operational data such as process information, project requirements, and material storage information. They connect with automatic AGVs, automatic trusses, tool and fixture warehouses and other equipment downstream to obtain various input and output signals of the equipment support layer, send production instructions to each device and receive equipment feedback results in real time.

[0057] Specifically, the MES system support functions of this solution include process management, planning management, production execution, quality management, line-side warehouse management, basic information, kanban management, exception management, production resources, system settings and other modules.

[0058] Specifically, for basic information management, the central control system can mainly manage the basic data of the workstations under the management of the workshop. Through the basic information maintenance configured in the workstation, the basic information of the workstation can be created. It is also possible to add, delete, modify, query, and export the basic information of the workstation, and the basic information can be created by importing a fixed-format EXCEL template. Basic information management is one of the core components of the digital maintenance system. It ensures the accuracy and real-time nature of all relevant data and provides necessary information support for other modules. The central control system is responsible for the management of all workstations in the workshop, including basic data maintenance, allowing the creation, update, and management of detailed information for each workstation. The maintenance of the basic information of the workstation includes the code, name, location, etc. of the workstation, and also supports operations such as data import, addition, deletion, modification, and query, which facilitates flexible management and updating of data.

[0059] Basic material data is maintained in the MES system. If the upstream system can support it, the basic material data can be directly interacted and synchronized. The MES system is the core of material data management. It contains detailed information about materials, such as material code, name, specification, inventory status, etc. If there is an upstream system (such as ERP, Enterprise Resource Planning system), it can interact with the MES system to automatically synchronize material information, reduce manual input, and improve data accuracy and real-time performance. It can mainly manage the following data:

[0060] User basic data: operations such as adding, deleting, modifying and checking user basic information and organizational relationships; user-related basic information such as work number and phone number. The MES system records the detailed information of all users, including user work number, phone number, email address, position, etc., and supports adding, deleting, modifying and checking user information. The management of user basic data ensures that each user in the system has a clear identity and contact information, which facilitates internal communication and management;

[0061] User roles: assign and maintain permissions for different user roles to form different role classifications; assign corresponding roles to users to achieve effective permission control, assign specific roles to different users, and each role has different permissions, such as data viewing, modification, approval, etc., to achieve effective permission control. Role permission management ensures the security of the system, prevents unauthorized personnel from accessing sensitive information, and also facilitates the standardization of operating procedures;

[0062] Notification message push management: The MES system has a system-wide message push function. The MES system has a built-in message push function that can push notifications such as production tasks, abnormal situations, and approval requests to specific users to ensure timely delivery of information. Through message push, users can understand the dynamics of the system in real time and quickly respond to production needs or abnormal situations;

[0063] Menu management: basic maintenance of all menus. The menu structure is maintainable and menu items can be added or deleted as needed to facilitate user operations. Menu management ensures the neatness of the system interface and the scalability of functions, and provides a personalized operating environment.

[0064] Production line station management: Production line management can add, delete, modify, and query production lines. The data includes production line codes and production line names. The MES system supports the management of the entire production line, including the addition, deletion, modification, and query of production lines, and records basic information such as the production line code and name. Production line station management ensures a clear production layout and facilitates adjustment and optimization of production lines.

[0065] Workstation management: Workstations can be added, deleted, modified, and queried. The data includes the workstation code, workstation name, and the production line to which it belongs. For specific workstations, detailed maintenance can be performed, including adding, deleting, modifying, and querying workstations, recording the workstation code, name, and production line information. Workstation management refines the production links, ensures that the responsibilities and functions of each workstation are clear, and facilitates task allocation and execution monitoring.

[0066] Specifically, for process management, there are 7 products on site. The overhaul and maintenance processes of these 7 products are planned (the overhaul process includes the minor repair process), and the process is selected according to the situation during the disassembly process. Whether it is an overhaul process or a minor repair process, it is necessary to manually select the process in the process according to the actual situation, select the required process and confirm it, and the MES system will execute the maintenance of related products according to the selected process. The process consists of work instructions, maintenance elements such as people, machines, materials, and environment, and work steps. The work steps include data collection steps, maintenance steps, must-replace / replacement list confirmation steps, inspection steps, and transfer steps. The process planning is carried out for 7 different products on site, including two maintenance modes: overhaul and minor repair. The overhaul process is usually more complicated than the minor repair process, including more processes and checkpoints. During the disassembly process, according to the specific condition of the electric wheel, the staff can flexibly choose the overhaul or minor repair process. This selection is based on the preliminary diagnosis of the electric wheel, such as the degree of wear of the parts and the type of fault. Whether it is a major overhaul or a minor overhaul, it is necessary to manually select specific procedures based on the actual situation of the electric wheel. These procedures include various operating instructions, required personnel, machines, materials, environmental conditions, and specific work steps. There are many types of work steps, such as data collection steps (used to collect key parameters and data), maintenance steps (used to perform specific repair or replacement operations), must-replace / replacement list confirmation steps (used to confirm the list of parts that need to be replaced), inspection steps (used for inspection of finished products), and transfer steps (used for the transfer of materials or workpieces).

[0067] Process management (maintenance process planning): mainly includes AGV path configuration. AGV equipment performs tasks and sends material pallets from the starting position to the end position, which is a path. AGV path configuration is a key link in process management. It involves entering the destination and recovery path of each pallet into the system so that when performing tasks, AGV can automatically identify the logistics path and transport the materials from the starting position to the end position. Through AGV path configuration, the efficient flow of materials is ensured, the workload of manual handling is reduced, and the accuracy and safety of logistics are improved. It is necessary to enter each destination and recovery path of each pallet into the system so that the system can automatically call it. There are 7 products on site. The overhaul and maintenance processes of these 7 products are planned (the overhaul process includes the minor repair process), and the process is selected according to the situation during the disassembly process. Whether it is an overhaul process or a minor repair process, it is necessary to manually select the process in the process according to the actual situation, select the required process and confirm it, and the MES system will execute the maintenance of related products according to the selected process. The process consists of operation instructions, maintenance elements such as people, machines, materials, and environment, and work steps. The work steps include data collection step, maintenance step, necessary replacement parts / replacement parts list confirmation step, inspection step, transfer step, etc. The specific configuration process is as follows:

[0068] Workstation configuration: It can input all maintenance workstations on site and bind personnel, equipment, AGV stations and workstations so that the system can associate the material requirements of the workstations with the AGV stations. It allows the input of all maintenance workstation information, including workstation codes, names, etc., and binds the workstations with the corresponding personnel, equipment and AGV stations. Through such configuration, the system can automatically associate the material requirements of the workstations with the logistics paths of the AGVs to realize intelligent distribution of materials.

[0069] Tool and tooling configuration: Configure the tools and tooling required for the products to be overhauled on the production line, and configure the tools and tooling needed during the overhaul process to ensure that each workstation can call on the correct tools and tooling when needed, thereby improving work efficiency and safety;

[0070] Equipment configuration: Bind the equipment required for each process of the production line so that it can be checked before production and called during maintenance. Bind the equipment required for each process of the production line to the system so that the equipment status can be checked before production and called during maintenance as needed.

[0071] Quality inspection configuration: Configure the quality control items of the production line, such as flaw detection, testing, load testing and other quality processes, set key points of quality control, such as flaw detection, size inspection, load testing, etc., to ensure that the quality standards of the production process are complied with. At the same time, the system can record and track these quality data for subsequent analysis;

[0072] Work instruction display: For semi-automatic workstations, the system supports uploading and displaying work instructions. It supports displaying work instructions on semi-automatic workstations, providing operators with clear step-by-step instructions and specifications, reducing operating errors and improving production consistency and quality.

[0073] Process change: When changing the content of maintenance process planning, the change process needs to be followed. During the production process, if the process needs to be changed, such as adding or modifying a process, the system provides a change process to ensure the compliance of the change and the integrity of the records. Change management also includes the approval and implementation tracking of the change content to ensure the stability and efficiency of the production process.

[0074] Specifically, for production management, 7 process routes are edited for 7 electric wheel models. The process routes are mainly for the creation and maintenance of required replacement parts and optional replacement parts and processes. The required replacement parts and optional replacement parts list is the material list for the entire electric wheel.

[0075] For each process, a production order is created based on the workstation, tools, equipment, process parameters, and action points (trigger points for calling automated equipment such as overhead cranes or AGVs), or a production order is accepted from the upstream system. The workshop planner creates a production task based on the production order. This task is a workstation-based task, and each workstation has a large task.

[0076] Each workstation corresponds to multiple processes under a large task, and each process corresponds to various points of the AGV. For example, the inspection station corresponds to the three-coordinate measurement process and the 3D scanning process. The three-coordinate measurement process and the 3D scanning process correspond to the three-coordinate measurement points and 3D scanning points. There can be multiple points.

[0077] Daily inspection is required before starting a workstation task, mainly for the inspection of the tools, equipment, materials and environment of the workstation. On-site personnel only need to click to confirm. Only after completing the daily inspection can the production task be executed.

[0078] After completing daily inspection, the operator needs to start work on the major tasks at the workstation. If it is a disassembly or assembly workstation, the system automatically calls the intelligent overhead crane to the workstation. Then the workers at the workstation manually operate the overhead crane.

[0079] Before the overhead crane lifts the workpiece to the equipment, the operator needs to unbind the single workpiece and the pallet. If it is a batch of workpieces, the operator needs to manually input the workpiece into the system, and the system automatically unbinds it by default after input. When the workpiece and the pallet are untied, the system automatically considers the workpiece to start the task execution, and records the start time and completion time of the workpiece task. The running time of all workpieces in this station is the working time of the personnel in this station.

[0080] After the inspection is completed, the operator calls the intelligent overhead crane and then lifts the workpiece to the pallet for binding. After binding, the operator selects the next station for each workpiece in the system. For example, if the next flow station of the workpiece is the three-coordinate inspection station and the 3D scanning station in the large inspection station, the operator needs to select the three-coordinate inspection station and the 3D scanning station on the workpiece flow page. After selecting the station, call the AGV, and the AGV will automatically deliver the workpiece to the selected station in order according to the logic.

[0081] After the personnel select the workstation information for delivery, the system will automatically generate the corresponding workstation tasks. For example, if the personnel at the previous workstation selects the workpiece and the next workstation is a three-coordinate inspection workstation and a 3D scanning workstation, the system will directly generate three-coordinate inspection workstation and 3D scanning workstation tasks. If several workpieces are delivered, several workstation tasks will be automatically generated. After receiving the workpiece, the personnel at the inspection workstation will manually start the work. After the work is completed, the operator needs to unbind the workpiece at this workstation. After all the workpieces at this workstation are unbinded, the AGV will pull the remaining material pallets and deliver them to another workstation.

[0082] Specifically, for production scheduling management, the revision order is created / maintained autonomously in the MES system. The main contents are as follows:

[0083] Maintenance task management: In the MES system, maintenance tasks can be created based on the maintenance order. Maintenance task management is based on the MES system to create specific maintenance tasks based on the maintenance order; the maintenance order usually contains information such as the model, quantity, and estimated completion time of the electric wheel that needs to be repaired. After receiving the maintenance order, the MES system can automatically generate or adjust the maintenance tasks according to the preset process flow and production line resources, including the task priority, completion time, required resources (such as personnel, equipment, materials), etc.; this step ensures that each maintenance task has a clear plan and execution plan, which is convenient for subsequent tracking and management;

[0084] Pause of maintenance tasks: When an abnormality occurs on site, relevant personnel can pause the maintenance tasks in progress. The suspended tasks do not need to be executed. When the processing is completed, they can be continued in the system. During the production process, various abnormal situations may be encountered, such as equipment failure, material shortages, personnel scheduling problems, etc., which may affect the normal execution of maintenance tasks; at this time, relevant personnel can pause the maintenance tasks being executed through the MES system. The suspended task will be temporarily stopped until the abnormal situation is resolved. Then, the operator can reactivate the task in the system to continue its execution. This flexibility enables the system to adapt to emergencies on the production site, avoid unnecessary production stagnation, and ensure the quality and safety of task execution;

[0085] Maintenance task modification: After the maintenance task is created but before it is issued, the relevant personnel can modify it according to the actual situation. After the maintenance task is created but before it is issued to the specific workstation, the relevant personnel can modify the maintenance task according to the actual needs of the site, including task details, resource requirements, completion time, etc. Modification of maintenance tasks needs to be done in the MES system to maintain the uniformity and accuracy of data; this dynamic adjustment capability enables the digital maintenance system to quickly respond to changes in production needs, optimize resource allocation, and improve production efficiency;

[0086] Maintenance tasks are issued. Only issued tasks can generate corresponding tasks. Maintenance tasks can only be started and executed after they are confirmed and adjusted and formally issued to relevant workstations through the MES system. Issuing maintenance tasks is a formal step in production scheduling. It transmits task information to front-line operators and equipment, triggering the preparation work of the workstation, such as material preparation, tool and fixture preparation, equipment preheating, etc. Only issued tasks can generate specific operation instructions, ensuring the orderliness and effectiveness of production scheduling.

[0087] Task feedback: Operation feedback, task fulfillment and other information, you can specify the date to print relevant reports. During the production process, operators feedback operation progress, task completion, equipment status, material consumption and other information through the MES system. These feedbacks are real-time and can be viewed immediately in the system, which is convenient for dispatchers to monitor production conditions and adjust production plans in time. In addition, the MES system also supports report printing, allowing users to generate relevant production reports on a specified date, such as task completion reports, equipment usage reports, material consumption reports, etc. These reports not only provide data records of the production process, but can also be used for subsequent analysis and decision-making, helping management optimize production strategies, improve production efficiency and reduce costs.

[0088] Specifically, for production execution management, the system automatically generates inspection tasks once in the morning and once in the evening, such as material inspection, equipment inspection, safety inspection, and tool and fixture inspection. The specific contents are as follows:

[0089] Task dispatching: After the maintenance task is issued, the maintenance task is generated according to the maintenance order. The status of the maintenance task can be viewed on site. Task dispatching mainly dispatches specific maintenance tasks to individuals, so that the individual maintenance execution status can be managed. At the same time, the site can add personnel to report work at any time for statistics; before the maintenance task officially begins, the MES system will dispatch the task to the specific operator. This is usually after the maintenance task is issued, the system automatically matches and assigns the task to the corresponding operator according to the preset scheduling rules and personnel capabilities. Operators can view the maintenance tasks they are responsible for through industrial computers or other mobile terminals, and understand the detailed requirements of the tasks, such as the processes to be performed, material requirements, and preparation of tools and tooling. At the same time, the task dispatching mechanism also allows on-site managers to add or adjust operators in real time to cope with sudden changes in manpower demand and ensure the smooth execution of production tasks;

[0090] Task status feedback: Real-time feedback of maintenance status, operation progress, personnel and other information; during the execution of maintenance tasks, the system collects and updates the task status in real time, including maintenance progress, equipment status, material consumption, operator work status and other information. These status information are fed back to production scheduling personnel and management through the MES system, enabling them to monitor production progress and resource usage in real time, adjust production plans in a timely manner, and handle possible abnormal situations;

[0091] Process information collection: From the time the electric wheel enters the factory to the last process, the MES system collects maintenance process information; from the time the electric wheel enters the factory to the final shipment, the MES system will track and collect all data information related to the maintenance process, including but not limited to material usage records, equipment operation data, tooling usage information, quality inspection results, personnel working hours, etc. The collection of this information helps to form a complete production record, providing a detailed data foundation for subsequent quality tracing, cost analysis, production optimization, etc.

[0092] On-site execution management: manage the start and completion of on-site maintenance tasks. Operators obtain work dispatch information to perform start / completion operations. The system generates relevant information and feeds back to the maintenance tasks in real time. It is mainly divided into automatic workstations and semi-automatic workstations. Automatic workstations report work by themselves, and semi-automatic workstations require manual reporting. The on-site execution management module is responsible for managing the on-site execution of maintenance tasks, including the start and completion of tasks. At automatic workstations, equipment can communicate directly with the MES system and automatically report the start and completion status of tasks; at semi-automatic workstations, operators need to manually report work through industrial computers or handheld terminals to report the progress of task execution. This management mechanism ensures the transparency of production tasks and facilitates on-site managers to promptly understand the status of task execution and conduct effective resource scheduling and task coordination.

[0093] Work instruction display: The work instruction content is displayed on site; the operators operate according to the work instruction. The control points and execution information set for key processes are recorded and queried; the work drawings or other notes and other information are displayed; the work instructions and related drawings and notes are displayed on site through digital means to provide operators with clear work instructions. Operators operate according to the instructions displayed by the system, and the system records the execution information of key processes, including the tools, equipment, work steps, inspection results, etc., which will be used for process quality control and subsequent process optimization;

[0094] Material traceability: Collection of component codes, location and other information of key components; Summarize all workpiece inspection reports and generate data packages. Bind with products to facilitate subsequent traceability; MES system supports traceability management of key materials and components, and forms a full life cycle record of materials by collecting and storing material codes, location information, inspection reports, etc. This record is bound to specific products, making it convenient to query the use of materials and inspection results in the production process when needed, ensuring the traceability of product quality;

[0095] Material coding management: On-site operators will laser print the code for material inspection according to the system. If it cannot be printed, they will use labels to print it. In order to facilitate the management of materials and parts, the system will generate a unique code for each key material and mark the code on the material by laser printing or label printing. This coding management mechanism ensures the uniqueness of each material in the production process, facilitates the system to track the flow of materials, and also facilitates on-site operators to quickly identify and call the required materials, thereby improving work efficiency.

[0096] During the specific implementation process, after obtaining the basic information, the above method also includes the following steps: obtaining transportation information, wherein the above transportation information includes the equipment to be transported, the transportation starting point, the transportation path and the transportation end point; according to the above transportation information, controlling the AGV equipment to travel to the above transportation starting point, and transporting the equipment to be transported to the above transportation end point along the above transportation path; storing the above transportation information in the above MES system.

[0097] In this solution, the MES system can be integrated with AGV equipment to realize the automated handling of materials and equipment. The integration of the MES system and AGV not only improves the efficiency and accuracy of logistics, but also provides strong data support for production management, promotes the intelligence and refinement of workshop management, and thus improves the efficiency and quality of the entire maintenance process.

[0098] Specifically, in the digital maintenance process, whenever equipment or materials need to be transported from one station to another, the MES system will collect relevant transport information. This information may include: specific information about the equipment or materials to be transported, such as equipment name, material number, quantity, etc.; the starting point of the transport, that is, the current location of the equipment or material; the end point of the transport, that is, the destination to which the equipment or material needs to be transported; and the transport path, that is, the safe and efficient route planned by the system for the AGV.

[0099] Specifically, based on the acquired handling information, the MES system will send instructions to the AGV system to control the AGV equipment to travel to the handling starting point. After receiving the instructions, the AGV will automatically transport the equipment or materials to be transported from the starting point to the end point according to the specified handling path. The driving and handling process of the AGV equipment is completely automatically controlled by the MES system without manual intervention, which improves the handling efficiency and reduces labor costs and potential risks in the handling process.

[0100] Specifically, during the handling process, all handling information, including equipment information, starting point, end point, path, handling time, etc., will be recorded and stored in the MES system. This storage process provides a detailed data foundation for subsequent production scheduling optimization, equipment maintenance, performance analysis, and problem tracing. By analyzing the stored handling information, production bottlenecks can be discovered, handling paths can be optimized, and even equipment maintenance needs can be predicted, thereby further improving production efficiency and workshop management level.

[0101] Specifically, the generation of handling information can be based on multiple factors such as the scheduling of the maintenance process, bill of materials, equipment status, and workstation requirements. The MES system can automatically identify these requirements and generate handling information, reducing human errors and time waste. The handling path of the AGV can be automatically planned by the MES system, taking into account the dynamic distribution of other AGVs, material vehicles, and personnel in the workshop to avoid collisions and congestion, and ensure safe and efficient handling. The MES system performs real-time monitoring during the AGV handling process. Once any abnormality is detected (such as AGV equipment failure, material failure to arrive on time, etc.), the system can immediately adjust the handling plan or notify relevant personnel to avoid production interruption. The handling information stored in the MES system can be integrated and analyzed with other production data (such as equipment operation status, material consumption, workstation utilization, etc.) to provide data support for production decisions. For example, by analyzing the handling frequency and path, the warehouse layout or workstation design can be optimized to reduce the handling distance and time. The MES system usually has a visual interface that can display the current location, handling status, and estimated arrival time of the AGV in real time, providing on-site managers with intuitive monitoring methods to facilitate scheduling and decision-making.

[0102] Specifically, AGV equipment management mainly includes AGB task creation and maintenance. It includes the following contents:

[0103] Path configuration: Create / maintain AGV paths; this means that in the MES system, administrators or system engineers can plan and adjust the AGV's travel path. Path configuration is one of the core functions of the AGV system, which allows users to create or modify the AGV's navigation path based on the layout and needs of the production or maintenance line. These paths can be fixed or dynamically adjusted according to real-time needs to ensure that the AGV can travel efficiently and safely in the workshop and complete the material handling task;

[0104] AGV point management: point creation, new / maintaining AGV points; point management refers to the management of AGV docking points or operation points in the MES system. Each workstation or material storage area has its own specific AGV docking point, which needs to be accurately defined in the system so that the AGV can arrive and leave accurately. By creating and maintaining these docking points, it can ensure smoother logistics connection between AGV and each workstation, reducing waiting time and manual intervention during the handling process;

[0105] AGV call management: Through system integration, workers can call AGV equipment for materials through industrial computers, and AGV will deliver pallet materials to relevant workstations. AGV call management is a key function to achieve automatic material delivery. When a workstation needs materials, the operator can send a demand signal to the AGV system through the industrial computer, specifying the required material type and quantity. After receiving the call, the system will automatically dispatch the AGV to the designated material storage area to pick up the materials, and then deliver them to the called workstation. This on-demand calling mechanism reduces the waiting time of logistics and improves the response speed and flexibility of material distribution;

[0106] AGV monitoring and management: The system monitors the status of the equipment and provides real-time feedback on the execution status. The monitoring and management function ensures the stable operation and efficient scheduling of the AGV system. Through real-time communication with the AGV, the MES system can monitor the current status of each AGV, including its location, battery status, operating mode, task progress and other information. This information is fed back to the MES system in real time, allowing managers to instantly grasp the operating status of the AGV, optimize task scheduling, avoid equipment failures and traffic jams, and also help to quickly locate and solve problems when failures occur.

[0107] In some embodiments, after obtaining the basic information, the method further includes the following steps: obtaining flaw detection information, wherein the flaw detection information is information of defect identification results of the electric wheel components collected by the flaw detection equipment when the electric wheel components enter the flaw detection station by the flaw detection equipment started by the MES system; generating a test report based on the flaw detection information, and storing the flaw detection information and the test report in the MES system.

[0108] In this solution, the flaw detection process and the management of flaw detection data can be automated through flaw detection equipment. This automated flaw detection process and data management greatly improves maintenance efficiency and quality control level, and is an important part of the digital maintenance system.

[0109] Specifically, when the electric wheel parts enter the designated flaw detection station, the MES system automatically starts the flaw detection equipment associated with the station. This process can be triggered by RFID, QR code scanning or other automated identification technologies to ensure automatic startup of the equipment and accurate identification of the parts. Once the flaw detection equipment is started, it automatically collects the defect identification results of the electric wheel parts. These results usually include key information such as the type, size, and location of the defect, which is used to evaluate the health and safety of the parts.

[0110] Specifically, based on the defect identification results collected by the flaw detection equipment, the MES system will automatically generate a detailed inspection report. The report not only contains specific defect information, but also includes additional data such as the parameter settings of the flaw detection equipment, operation time, operator information, etc. This information is crucial for problem tracing and quality control. The automatic generation of inspection reports avoids the subjectivity and errors of manual reports and ensures the accuracy and consistency of data.

[0111] Specifically, all collected flaw detection information and generated inspection reports will be stored in the MES system. This storage is not only for quality control in the current maintenance process, but more importantly, it provides a data basis for possible parts tracing, fault analysis and equipment maintenance in the future. The long-term preservation of data enables enterprises to establish a comprehensive quality database for continuous improvement of production processes and product design.

[0112] Specifically, through automatic identification technology, such as RFID, the information of the arriving electric wheel components can be determined instantly, triggering the start of the flaw detection equipment without manual operation, reducing waiting time and improving efficiency. The defect data collected by the flaw detection equipment is transmitted to the MES system in real time. The system uses built-in algorithms for analysis to determine the degree of damage and safety of the components, automatically generates a test report, and provides instant feedback. All flaw detection information and test reports are bound to the unique identification of the component (such as the serial number), so that when the component fails or needs to be repaired, its flaw detection history and test results can be traced back, providing a basis for problem solving. By analyzing historical flaw detection data, the MES system can identify potential failure modes and development trends, provide early warnings, take preventive measures, reduce unplanned equipment downtime, and improve overall production efficiency. The MES system can also monitor the performance indicators of flaw detection equipment, such as operating time, failure rate, and maintenance records, for equipment performance optimization and preventive maintenance.

[0113] For example, during a specific overhaul of the electric wheel of a large-tonnage mining truck, when the drive motor component in the electric wheel is automatically transported to the horizontal magnetic particle inspection station by AGV, the MES system automatically identifies the identification information of the motor component and starts the horizontal magnetic particle inspection equipment. The inspection equipment automatically inspects the drive motor and identifies surface cracks and internal defects. The inspection results are transmitted to the MES system in real time. The system automatically generates an inspection report based on the preset judgment criteria. The report lists in detail the type, size and location of each defect, as well as the parameter setting information of the inspection equipment. The report and all inspection data are stored in the MES system and bound to the unique serial number of the drive motor component, providing important data for subsequent quality tracking and fault analysis. At the same time, if the inspection report shows that a certain type of defect frequently occurs in multiple components, the MES system will automatically trigger the exception management process and notify the relevant engineers to review the equipment design or process flow to prevent similar problems that may occur in the future.

[0114] Specifically, for quality management, process inspection management mainly manages the quality during the production process. The system plans important processes and nodes in the manufacturing process, and conducts special inspections according to the planned items. In the pilot company, special inspections are used to collect production process data, which serves as the basis for subsequent data analysis and presentation.

[0115] Quality management personnel and process management personnel can set data collection action points in the process route and enter data collection nodes and collection item content. The data collection item content can be bolt torque, personnel information, dimensional measurement data, and flaw detection data. The data collection task will be initiated according to the specified nodes during production execution. The system will automatically prompt the data collection task and the staff will enter the data. The entered data items are all bound to the product batch number. All entered data can be queried by the batch number, realizing quality traceability without blind spots in the whole process.

[0116] The maintenance MES system supports the full process traceability of even replacement parts or necessary replacement parts. After the operator replaces the necessary replacement parts or occasional replacement parts, the necessary replacement parts or occasional replacement parts will be placed in the relevant tooling. The necessary replacement parts or occasional replacement parts will be scanned and bound, and the tooling information bound to the necessary replacement parts or occasional replacement parts will be stored in the system. When the relevant parts need to be traced, they can be directly queried in the system.

[0117] Specifically, for process inspection management, to grab the flaw detection equipment report, it is necessary to grab the flaw detection report (magnetic particle flaw detection), and ultrasonic flaw detection only requires confirmation.

[0118] The specific contents are as follows:

[0119] Capture inspection equipment reports: Inspection reports need to be captured; this function allows the MES system to directly communicate data with inspection equipment (such as flaw detection equipment) and automatically extract inspection reports. For example, after completing the flaw detection, the magnetic particle flaw detection equipment will generate a flaw detection report, which contains key information such as the flaw detection results, inspection location, and inspection time. The MES system can automatically capture these reports and integrate them into the records of maintenance tasks to form a complete quality data chain. For ultrasonic flaw detection, although the report is also automatically generated, because ultrasonic flaw detection may involve more real-time operations and manual judgment, the MES system mainly provides a confirmation interface for the operator to confirm the flaw detection results, and then the system automatically records the confirmation information and also includes it in the quality data chain;

[0120] Grab the test equipment report: It is necessary to interact with the load test bench to grab the load test report; during the maintenance process, the electric wheel may undergo a load test to verify its performance and reliability. After the load test bench completes the experiment, it will generate a test report, including test parameters, result analysis, test time and other data. The MES system can directly interact with the load test bench to grab the load test report, and bind these reports to specific maintenance tasks and electric wheel products to form a complete quality inspection record;

[0121] Quality traceability: During the maintenance process, process information data such as quality control (flaw detection, testing, load testing) can be viewed and traced. The quality traceability function is an important feature of the entire digital maintenance system. It allows users to query data and trace results for key quality control points (such as flaw detection, testing, load testing and other processes) during or after the maintenance process. Through this function, the system can provide all quality inspection data of each electric wheel during the maintenance process, including test reports, test reports, test time and results, etc., to ensure the transparency and traceability of each product quality control. This is extremely important for subsequent quality analysis, fault diagnosis and production optimization. At the same time, it provides users with quality confidence and increases the responsibility and reliability of the system.

[0122] During the specific implementation process, after obtaining the basic information, the above method also includes the following steps: obtaining abnormal reporting information, wherein the above abnormal reporting information includes one or more of abnormal workstations, abnormal products and abnormal processes reported at the work site; pushing the above abnormal reporting information to the target terminal used by the target object, wherein the above target object is the object responsible for maintenance.

[0123] In this solution, the MES system can respond to on-site abnormal reports and transmit abnormal information to the person responsible for maintenance in a timely manner. The abnormal reporting and response mechanism of the MES system not only speeds up problem handling and improves production efficiency, but also provides valuable data for fault analysis and preventive maintenance. It is a key link in ensuring quality control and production safety in the digital maintenance system.

[0124] Specifically, if the on-site operator encounters any unexpected events during the maintenance process, such as equipment failure, material shortage, process problems, etc., he can immediately report the abnormality on the industrial computer or mobile terminal. The reporting information should at least include the workstation where the abnormality occurred, the products involved, and the specific circumstances of the abnormality, including but not limited to the type of fault, equipment status, material status or operation problems, etc. This instant abnormality reporting mechanism ensures the rapid identification and location of problems, reduces the retention time of problems, and improves the response speed.

[0125] Specifically, once the exception report information is submitted, the MES system will automatically identify and determine the target object that is most suitable for handling the exception, which may be the equipment maintenance team, material management personnel, process engineers or on-site supervisors, depending on the type of exception and the scope of impact. The system will quickly push the exception information to the target object through SMS, email, industrial computer display or dedicated maintenance team terminal, etc., to ensure timely communication of information so that the target object can take immediate action to solve the problem or make necessary repairs. This instant information push mechanism avoids delays in information transmission and ensures a quick response to abnormal situations.

[0126] Suppose that at the assembly station of the electric wheel, an on-site operator found an abnormality in the bolt connection of the electric wheel during the assembly process, and suspected cracks. The operator immediately reported the abnormality on the industrial computer, describing the abnormal situation in detail, including the abnormal station code, the serial number of the electric wheel product involved, and the abnormal description. After receiving the abnormality report information, the MES system automatically identified the abnormality type as "equipment failure" and pushed the abnormality information to the industrial computer and mobile terminal of the equipment maintenance team. After receiving the notification, the maintenance team immediately reviewed the relevant equipment history records and operation manuals, evaluated the possible causes and solutions of the bolt connection failure, and quickly dispatched maintenance personnel to the site for inspection and repair. At the same time, the MES system updated the progress of the abnormality handling and notified other operators at the assembly station to avoid similar problems from happening again. After the maintenance is completed, the maintenance team reports the maintenance results through the MES system, and the system automatically stores the abnormal information, handling process, and repair results in the database for future reference and analysis.

[0127] Specifically, for exception management, after the on-site personnel find the exception, they will report the exception, mainly managing the exception reports that occur during the production process. When an abnormal situation occurs during the production process, the system supports the function of reporting the abnormal situation. The user selects the workstation, product, exception type and other information that needs to be reported. The system obtains the product exception classification and exception support architecture, and enters the exception problem description. After the exception report is completed, the system automatically pushes the situation to the supporter of the exception support architecture, and the supporter handles the abnormal situation. The system automatically upgrades the unhandled exceptions according to the response level and response time of the product support architecture until the exception is closed.

[0128] Specifically, according to the abnormal basic configuration information, the responsible person is notified step by step according to the abnormal type to report and handle. The specific contents include the following:

[0129] Maintenance exception reporting: Maintenance process exception reporting reports the exceptions that occur during the maintenance process. You can select workstations, products, exception types and other information; during the maintenance process, when operators or equipment detect any abnormalities, such as equipment failure, material shortages, operating errors, etc., you can report the exceptions through the MES system. When reporting an exception, the operator needs to select the workstation where the exception occurred, the affected product, the type of exception and other detailed information. This reporting mechanism ensures the accuracy of the exception information and facilitates subsequent processing and analysis;

[0130] Exception handling: According to the exception classification and exception support structure, the system automatically pushes the exception information to the support person. The support person handles it. Unprocessed exceptions are upgraded until the exception is closed; after the exception is reported, the MES system automatically pushes the exception information to the designated responsible person or processing team according to the preset exception classification and support structure. After receiving the information, the responsible person needs to take immediate measures to resolve the exception, such as equipment maintenance, material replenishment, operation guidance, etc. If the exception is not resolved within the specified time, the system will automatically upgrade the exception level and notify the higher-level responsible person or management department to ensure timely handling of the problem. This mechanism improves the efficiency of exception handling while also reducing the impact of exceptions on production progress;

[0131] Maintenance exception query: The system records exceptions and handling results, and can query exception information according to various conditions. Users can obtain exception handling dynamics, reply content and other information in real time. Display relevant information in the visual dashboard. The MES system not only records the occurrence and handling process of exceptions, but also provides an exception query function. Users can query exception information according to various conditions, such as exception type, occurrence time, processing status, etc. The system will display the details of the exception, including exception description, handling results, handling personnel and processing time. The query results can be displayed in the visual dashboard, which is convenient for on-site managers to monitor abnormal situations in real time, conduct production scheduling and resource allocation. In addition, the accumulation of abnormal data also provides valuable analysis information for subsequent production process optimization. By analyzing the causes and frequency of abnormalities, the process flow and operating specifications can be improved in a targeted manner to reduce possible abnormalities in the future.

[0132] In some embodiments, after obtaining the basic information, the method further includes the following steps: obtaining material information, wherein the material information is information on logistics demand, use and circulation; importing the material information into the MES system; generating material codes for materials without material codes, wherein the material codes are unique identifiers of materials; generating a replacement parts list using the MES system, wherein the replacement parts list is used to prompt the maintenance object to replace materials, and the replacement parts list at least includes the material information and / or the material codes.

[0133] In this solution, the MES system can be used to manage material information, generate unique identifiers for materials without material codes, and guide material replacement during the maintenance process through a replacement parts list. The MES system's management of material information not only solves the problem of missing material codes, but also guides material replacement through a replacement parts list, thereby improving the efficiency of maintenance work and the level of quality control.

[0134] Specifically, during the maintenance process, material information tracking and management are crucial. The MES system obtains material information from multiple sources, including material requirements from the logistics department, material usage records from on-site operators, and material flow information between different workstations. This information can be obtained through barcode scanning, RFID reading, manual input or other automated technologies, ensuring the accuracy and real-time nature of material information.

[0135] Specifically, the acquired material information is imported into the MES system for centralized management and analysis. The system's material module can receive and store this information, while supporting data query, statistics and analysis, providing strong data support for production planning, material management and cost control.

[0136] Specifically, during the maintenance process, some materials may not have been assigned codes in advance, especially those non-standard or temporarily added materials. The MES system can automatically generate material codes for these materials. The coding follows certain rules, such as combining product codes, dates and sequence numbers to ensure that each material has a unique identifier for subsequent material tracking and management.

[0137] Specifically, in the maintenance process, the MES system will automatically generate a replacement parts list based on the maintenance requirements of the electric wheel and the real-time status of the materials. The list lists the information of the materials that need to be replaced, including the material name, quantity, material code, and possible reasons for replacement. The replacement parts list is an important guidance document for on-site operators. It clearly lists all the materials that need to be replaced in the current maintenance step, thereby avoiding misuse or omission of materials and ensuring the smooth progress of maintenance work.

[0138] Specifically, based on historical maintenance records and the working status of the electric wheel, it is also possible to predict possible material needs in the future, prepare materials in advance, and avoid production delays due to material shortages. Track the use of materials in different maintenance steps, analyze material consumption patterns, identify material waste and optimization opportunities, and thus reduce material costs. Connect with AGV, intelligent stereoscopic warehouses and other equipment to achieve automated material distribution, improve the efficiency of material circulation, and reduce errors and time waste in manual handling.

[0139] Suppose that at the laser grinding station for inspecting the electric wheel, the operator found that the surface of a drive shaft component of the electric wheel was worn and a new drive shaft needed to be replaced. However, the drive shaft was not assigned a material code in the bill of materials of the electric wheel because it was a replacement part. The operator reported this situation on the industrial computer, and the MES system immediately generated a material code for the drive shaft, such as "P001202307001". The system automatically generated a replacement list based on the replacement requirements of the drive shaft, which detailed the name, quantity, material code and replacement reason of the drive shaft. The replacement list was displayed to the operator through the industrial computer. At the same time, the MES system notified the intelligent stereoscopic warehouse to obtain the new drive shaft and automatically delivered the drive shaft to the laser grinding station through the AGV. After confirming that the material information was correct, the operator began to replace the drive shaft, and the replacement list and material code were used as the basis for recording this replacement process, ensuring the traceability of material use and the standardization of the inspection process.

[0140] Specifically, for line-side material management, materials can be managed in the MES system. Basic material information can be created or imported in a specified format file, so that all basic material types in the system have unique codes, and the existing materials are manually updated in the MES system in real time. Interfaces will be reserved for interaction with upstream systems in the future.

[0141] During production execution, after disassembly is completed, the MES system will directly display the list of materials for the necessary replacement parts and allow the operator to select the materials that need to be replaced. After confirmation, the MES system will output the list, and the operator will pick up the necessary replacement parts according to the list. As the disassembly is completed, the MES system will generate a list of optional replacement parts at any time during the inspection process and provide the operator with selection. After confirmation, the MES system will output the list of materials, and the operator will pick up the optional replacement parts according to the list.

[0142] The MES system will automatically generate codes for mandatory parts and optional parts that do not have material codes. The coding rule is product code + date + 001. For large and important workpieces, the codes are manually entered into the MES system for storage and association based on the company's existing material codes, so that the production process can be traced for materials without material codes.

[0143] The MES system manages consumables and can record the types of consumables and their collection information, including the type, quantity, time, and recipient information of the consumables.

[0144] Specifically, for material management, the MES system manages key parts on site such as electronics (with their own material codes). For materials that do not have material codes, such as must-replace parts and optional parts, the system generates codes on its own, and the coding rule is product code + date + 001; the MES system can handle different types of materials, and for those key parts that come with their own material codes, such as electronic components, the system can directly identify and track them. For materials such as must-replace parts and optional parts that may not have specific codes, the system uses a mechanism to automatically generate codes. The coding rule combines product codes and dates, such as "product code + date + 001", which ensures that even materials without preset codes can obtain unique identification in the system for easy tracking and management. This coding mechanism not only increases the flexibility of material management, but also ensures the traceability of all materials during the digital maintenance process;

[0145] Mandatory parts / optional parts list: During disassembly, the system will generate a material requirement list based on whether it is a major overhaul or a minor overhaul. If it is a major overhaul, the system will directly inspect the corresponding mandatory parts list for public operator selection. After inspection, the system will display the optional parts list based on the inspection results, and the workers will select the optional parts from the list as needed. During the overhaul of the electric wheels of large-tonnage mining trucks, the system can generate a corresponding material requirement list based on the nature of the overhaul (major or minor overhaul). In the case of major overhauls, the system will automatically generate a list of mandatory parts for the operator's reference and selection. In the case of minor overhauls or when more detailed inspections are required, the system will dynamically display a list of optional parts based on the inspection results, and workers can select specific parts from the list for replacement based on actual needs. This intelligent list management method can automatically provide material requirement information based on the actual situation of the overhaul, reducing manual errors and material waste, while improving maintenance efficiency;

[0146] Process monitoring: The MES system monitors the process from materials to semi-finished products and then to finished products, and also monitors the flow of materials and tasks. Process monitoring is a core function of the MES system, which covers the entire process from material storage, use, testing to the final finished product. The system can track the status of materials in real time, including whether they have been used, the current workstation, whether a certain process or test has been completed, etc. In addition, the MES system can also monitor the flow of materials within the maintenance line, including the distribution, receipt, storage and other links of materials, to ensure the transparent and efficient flow of materials. This function is of great significance for timely detection of logistics bottlenecks, material shortages or retention, and optimization of production scheduling.

[0147] During the specific implementation process, after obtaining the basic information, the above method also includes the following steps: when receiving a resource usage demand, using the above MES system to store the above user-related information of the object requesting to use the resource, wherein the above resource usage demand is the demand for using resources and / or resource out of the warehouse, and the above resources include tools and / or tooling; when receiving a resource return demand, using the above MES system to generate task details, wherein the above task details include one or more of the above user-related information, the above resources collected, the collection time and the return time, and the above resource return demand is the demand for returning resources and / or putting resources into the warehouse.

[0148] In this solution, the MES system can be used to manage the resource usage and return process to ensure effective tracking and efficient use of resources. The automation and refinement of the MES system in resource management not only improves the efficiency of tool and tooling use, but also ensures the full traceability of resources, which helps to standardize the maintenance process and control costs.

[0149] Specifically, when field operators need to use specific tools or tooling, they can submit resource usage requirements to the MES system through an industrial computer or mobile terminal. The requirements may include the name, quantity, usage time, and requester information (such as name, work number, and contact information) of the required tools / tooling. After receiving the requirements, the MES system will automatically record the user-related information of the object (i.e., operator) requesting the use of resources, such as name, work number, etc., as well as the specific content of the requirements, including the type and quantity of the required resources. This recording mechanism helps track and manage resources, ensures that the use of resources can be traced, and also facilitates subsequent resource allocation and scheduling.

[0150] Specifically, when a tool or tooling is returned, the operator submits a resource return request to the MES system again through an industrial computer or mobile terminal. After receiving the return request, the system will generate a detailed task list. This task list includes the operator information of the returned resource, the actual resource list, the resource collection time, and the resource return time. By storing this information, the MES system can accurately track the use cycle of each tool or tooling, realize the full monitoring of resource use, and help resource maintenance and cost control.

[0151] In addition, the MES system automatically schedules and allocates the required tools and tooling according to production plans and maintenance tasks, reducing the complexity and errors of manual scheduling. The system updates the inventory status and usage of resources in real time to ensure that operators can understand the availability of resources at any time and avoid production delays caused by resource shortages. The MES system can monitor the abnormal use of tools and tooling, such as failure to return them after a timeout or failure to use them as planned, and send reminders or alarms in time to ensure the rational use of resources. When tools or tooling need to be repaired or reach the scrap standard, the MES system will automatically generate the corresponding repair or scrapping tasks, provide maintenance records and scrapping reasons recording functions, and facilitate the full life cycle management of resources.

[0152] Assume that at the three-coordinate inspection station of the electric wheel, an operator needs to use a torque wrench to inspect parts. However, since torque wrenches are not always available at each station, the operator submits the tool usage requirements to the MES system on the industrial computer. The system records the operator's work number, name, and contact information, as well as the number of torque wrenches required and the estimated time of use. Since torque wrenches are in stock in the intelligent stereoscopic warehouse, the MES system automatically dispatches the AGV to take out the torque wrench from the stereoscopic warehouse and deliver it to the three-coordinate inspection station. After receiving the tool, the operator begins the inspection work.

[0153] Once the inspection work is completed, the operator submits the tool return request on the industrial computer. The MES system then generates a task detail, which includes the operator's information, the number of torque wrenches collected, the exact time of collection and the time of return. This detail is stored in the system as a record of tool use and return, and is used for subsequent tool inventory management and usage statistics.

[0154] Specifically, for production resource management, it supports the management of production resources such as tools, tooling, equipment, etc. at the production site, and the tools and tooling are stored in the vertical warehouse for management.

[0155] Specifically, production resource management manages the basic information of tools and equipment, and clearly understands the information of tools and equipment. It provides tool scrapping function, tool repair function, equipment maintenance function, equipment failure function, and equipment inspection function. The specific functions are as follows:

[0156] Tool and tooling collection / return management: The MES system provides tool and tooling collection / return functions. When collecting tools and tooling, the system will store the information of the recipient. After returning, the system will close the task and generate a task detail. When operators need to use tools or tooling, they can collect them through the MES system. The system will record the information of the collector and the collection time. When the use is finished, the operator returns the tools or tooling, the MES system will close the collection task and generate a detailed collection / return record to facilitate tracking and analysis of the use of tools and tooling;

[0157] Tools and tooling access / recycling to intelligent three-dimensional warehouse management: MES system is integrated with the vertical warehouse system. Through production line process planning, during maintenance execution, the pre-configured outbound / inbound tasks of designated tools and tooling are executed at the preset action nodes, and the access / recycling tasks are supported. The outbound / inbound tasks can be issued manually. The system reads the inventory information of the intelligent three-dimensional warehouse and updates the inventory in combination with the tasks. Vertical warehouses (vertical warehouses) are used to store various tools and tooling. Through integration with the MES system, automation and information management are realized. The items in the vertical warehouse can be scheduled by the MES system at any time to meet production needs. At the same time, the system can update the inventory information of the vertical warehouse in real time; when the tooling reaches its service life or is damaged, the MES system provides a tooling scrapping function, which can record the scrapping status and reasons of the tooling, which is convenient for asset management and cost control. At the same time, the system also supports the recording and tracking of tooling repairs to ensure that the maintenance of tooling meets the standards. Regular maintenance of equipment is a key part of preventive maintenance. The MES system provides equipment maintenance plan formulation and execution tracking to reduce equipment failure rate. For equipment failures, the system can record failure information, including failure time, cause, and treatment measures, which helps to quickly respond and repair, and reduce production downtime. In order to ensure that the equipment is in good working condition, the MES system supports daily inspection of the equipment. Operators can use handheld terminals or industrial computers to check and confirm the equipment status. The system automatically records the inspection results to provide data support for subsequent equipment health analysis;

[0158] Bolt retrieval (there are empty spaces in the vertical warehouse) The condition for bolt management in the vertical warehouse is that all tools and fixtures can be stored in the vertical warehouse. If there are not enough grids, they cannot be managed. When managing bolts, only the number of bolts is managed, and nothing else is managed. When taking out bolts, the system quantity needs to be maintained, and manual intervention is required when recycling. After pressing the confirmation button, the system automatically fills the quantity. Bolts are stored in the vertical warehouse. When bolts are needed, the MES system will automatically or manually schedule the bolts to be shipped out of the warehouse and update the inventory information at the same time. When returning bolts, manual confirmation of the quantity is required, and the system will automatically adjust the inventory to ensure the accuracy of the bolt quantity and timely replenishment;

[0159] AGV pallet management: It can manage the basic information and status information of AGV pallets. The basic information includes the pallet name, number, and type, and the status information includes the current location and sealed status. The MES system can manage the basic information of AGV pallets, such as name, number, and type, as well as real-time status information, including the location of the pallet and whether it is sealed. This helps to optimize the task scheduling of AGVs and ensure the timely and accurate delivery of materials and workpieces;

[0160] Consumables management: basic data information of consumables, consumables collection information, and consumables collection data information. The MES system tracks and records the collection information of consumables, including the collection time, quantity, and collection person. At the same time, the system can summarize the collection data of consumables and conduct data analysis to help enterprises optimize the inventory management of consumables, reduce waste, and improve production cost control capabilities.

[0161] Specifically, for material flow management, the material flow between on-site workstations is mainly transported by AGV. According to the production process planning, AGV automatically distributes materials according to the material planning process between workstations. AGV automatically distributes materials between workstations. At the same time, when materials are needed, you only need to click the call material button, and AGV will deliver the materials needed for this workstation to the workstation.

[0162] In some embodiments, before using the MES system to store the above basic information, the method further includes the following steps: using digital twin technology to perform virtual mapping based on the above basic information to obtain a three-dimensional virtual model of the electric wheel.

[0163] In this solution, digital twin technology is used to create a three-dimensional virtual model of the electric wheel, which provides intuitive assembly guidance for operators and real-time fault analysis and maintenance guidance tools for remote experts, greatly improving the efficiency and quality of the maintenance process.

[0164] Specifically, digital twin technology is an advanced simulation model that integrates physical models, sensor data, operation history and other data to accurately simulate the performance and behavior of physical entities or systems. In the digital maintenance system of electric wheels, digital twin technology is used to create a three-dimensional virtual model of the electric wheel, which contains all the basic information of the electric wheel, such as structural design, material properties, dimensional parameters, assembly relationships, etc. Through this virtual mapping, the MES system can intuitively display the structure and status of the electric wheel, providing maintenance personnel with a visual work aid tool.

[0165] Specifically, based on the operating data of the electric wheel, the digital twin model can perform dynamic simulation to simulate the performance changes of the electric wheel under different working conditions, which helps to identify potential design defects and failure modes. Using the three-dimensional virtual model, the system can provide a virtual maintenance training environment, allowing new employees or operators to perform simulated operations in a real environment to improve their skill level and safety. Through the digital twin model, remote experts can view the operating status and test results of the electric wheel in real time, provide online guidance and technical support, optimize maintenance plans, and reduce downtime. Combined with historical operation and maintenance data, the model can perform intelligent optimization analysis, predict possible future failure points and maintenance needs, and provide a basis for production planning and resource allocation. The digital twin model, combined with the visual management function of the MES system, can display the actual position and status of the electric wheel on the production line, as well as the maintenance progress in real time, providing managers with an intuitive production monitoring interface.

[0166] Suppose that at the assembly station of the electric wheel, the operator finds that the assembly order and method of some parts are not clear enough when assembling the electric wheel assembly. At this time, the operator can call the three-dimensional virtual model of the electric wheel through the interface of the MES system. The model shows the assembly position, direction and order of each component in detail. The operator can rotate, enlarge and reduce the model to intuitively understand the assembly relationship and steps, avoid assembly errors and improve work efficiency. In addition, the operator can also use the virtual model to perform virtual assembly operations. The system will automatically check the collision risk and feasibility during the assembly process to ensure the smooth progress of the actual assembly process.

[0167] In another scenario, a remote expert discovered that the temperature of the motor of the electric wheel was abnormally high and suspected that there was a problem with the heat sink inside the motor. By calling the digital twin model of the electric wheel, the expert can conduct a virtual inspection of the motor's cooling system and simulate different heat sink designs and motor operating conditions to find out the problem. If it is confirmed that the problem is with the heat sink, the expert can guide the on-site personnel to conduct targeted inspections and replacements, avoiding unnecessary disassembly and waste, and improving the pertinence and efficiency of maintenance.

[0168] Specifically, the digital maintenance MES system platform based on the electric wheel of large-tonnage mining trucks combines digital twin reality technology to dynamically load the real-life 3D model of the production line. And combined with the joystick control device, the perspective can be switched at will, and every corner of the factory can be seamlessly browsed. In addition, the application of floating windows can display various real-time data on site, providing a basis for data visualization; the displayed model is as follows: Figure 5 and Figure 6 shown.

[0169] Specifically, the digital maintenance MES system platform based on the electric wheel of large-tonnage mining trucks has realized the alarm display for abnormal production line workstations. According to the automatic collection of real-time abnormal data of on-site equipment and abnormal alarms of personnel, it is displayed through a floating window to further improve the control ability of production line production. The application of data can also expose production problems and bottlenecks of production lines and effectively support management personnel to optimize the production process of production lines.

[0170] Specifically, the digital maintenance MES system platform based on the electric wheel of large-tonnage mining trucks realizes the display of the progress of production tasks at the production line stations; according to the acceptance of production tasks and the start of work reporting in the maintenance MES system by on-site personnel, the transparent sharing of production process information is realized in real time and effectively, and the on-site management personnel are effectively supported in controlling the production line tasks, thereby improving production.
