[0019] Figure 1 FIG. 1 shows a schematic diagram of a digital twin system of a bogie axle drive maintenance line provided by an exemplary embodiment of the present disclosure, as shown in FIG. Figure 1 As shown, the first digital twin system 100 includes a building information model 101, a data collection terminal 102, and a display terminal 103. The first digital twin system 100 can be implemented based on a computer device.

[0020] The first digital twin system 100 is used to simulate the structure of the bogie axle drive maintenance line.

[0021] The building information model 101 is used to simulate the bogie axle drive maintenance line. Here, the building information model 101 is BIM (Building Information Modeling).

[0022] The data acquisition terminal 102 is connected to the building information model 101 and is used to obtain the Internet of Things data on the bogie axle drive maintenance line and input the obtained Internet of Things data into the building information model 101.

[0023] Optionally, the IoT data collected by the data collection terminal 102 includes: status data and detection data.

[0024] The status data includes operating status, performance indicators, fault and warning information, usage history, configuration information, and energy consumption data. The status data is collected through sensors installed in the bogie axle drive maintenance line.

[0025] Here, the operating status refers to the operating status of the equipment, such as running, stopping, and pausing; performance indicators include temperature data, pressure data, speed data, vibration data, current and voltage data, displacement data, etc., which are used to evaluate the operating efficiency and wear degree of the equipment; fault and warning information are crucial for fault diagnosis and maintenance; usage history records the usage time and number of startups of the equipment, which helps to manage its maintenance cycle and lifespan; energy consumption data records the energy consumption of the equipment, which is used for energy management and cost control.

[0026] Figure 2 is a schematic diagram of the detection data. Figure 2 As shown in Figure 1, the inspection data is used to indicate detailed performance parameters and component status during operation, such as component wear, mechanical properties, electrical output, and other key performance indicators. Inspection data is mainly collected through sensors and professional diagnostic equipment.

[0027] The display terminal 103 is connected to the building information model 101 and is used to display the changes of the Internet of Things data in the bogie axle drive maintenance line simulated by the building information model 101.

[0028] Figure 3It is a schematic diagram of the bogie axle drive maintenance line. Figure 4 This is a schematic diagram of the structure of the bogie wheel axle drive. Figure 3 and Figure 4 The working process of the bogie axle drive maintenance line is explained.

[0029] like Figure 2 As shown, the bogie wheel axle drive maintenance line includes a drive disassembly area 301, a wheelset disassembly area 302, a wheel cake maintenance area 303, an axle maintenance area 304, an axle box assembly area 305, a drive assembly area 306 and a running-in test area 307 which are connected in sequence.

[0030] like Figure 3 As shown, the bogie wheel axle drive 400 includes: an axle box 401, a gear box 402, a wheel cake 403, an axle 404 and a traction motor 405. Two wheel cakes 403 are respectively installed on both sides of the axle 404, the two wheel cakes 403 and the axle 404 constitute a wheelset, the gear box 402 is installed on the wheelset, the traction motor 405 is connected to the axle 404, and the axle box 401 is installed at both ends of the axle 404.

[0031] The drive decomposition area 301 is used to decompose the gearbox 402, the axle box 401 and the traction motor 405 from the bogie wheel axle drive 400 to obtain the gearbox 402, the axle box 401, the traction motor 405 and the wheel set. For example, before decomposing the gearbox 402, it is necessary to remove the lower box drain plug of the gearbox 402, put the lubricating oil in the gearbox 402 into a designated storage container, and then decompose the gearbox 402 from the bogie wheel axle drive 400. It is also possible to record the vehicle number and position of the drive device, the traction motor 405, the wheel factory code and number, the gearbox 402, the suspension beam, and the number of the grounding device; during the decomposition process, the numbers of the axle box bearings, the axle box 401, the axle 404, the master and slave gears and other related accessories can be recorded. The wheelset disassembly area 302 is used to disassemble the wheelset to obtain the wheel axle 404 and the wheel cake 403. For example, before disassembling the wheelset, the wheelset needs to be hoisted onto the wheel withdrawal equipment, the guide sleeve is installed on the shaft head neck, the screw plug on the oil filling hole of the wheel cake 403 is removed, and the oil pipe connection joint is installed at the oil filling hole and tightened. Then the wheel withdrawal counter-press can be started to disassemble the tooth side wheel cake from the wheel axle 404. The disassembled wheel cake 403 is transferred to the wheel cake maintenance area 303 and the disassembled wheel axle 404 is transferred to the wheel axle maintenance area 304 by the overhead crane, thereby completing the wheelset disassembly operation.

[0032] The wheel cake repair area 303 is used to repair the wheel cake 403. Exemplarily, repairing the wheel cake 403 includes: disassembling and repairing the brake disc on the wheel cake 403, and then assembling the brake disc back to the wheel cake after the brake disc repair is completed. Optionally, the brake disc is automatically assembled by an assembly robot to achieve automation and standardization of brake disc assembly, thereby ensuring the assembly speed and quality of the brake disc.

[0033] The wheel axle maintenance area 304 is used to repair the wheel axle 404 and install the wheel axle 404 and the wheel cake 403 to obtain a wheelset. Exemplarily, repairing the wheel axle 404 includes: cleaning, measuring, flaw detection and other maintenance operations on the disassembled wheel axle 404 to ensure the quality of the wheel axle 404. When the wheel axle 404 and the wheel cake 403 are installed to obtain a wheelset, the wheel axle 404 and the wheel cake 403 can be hoisted to the wheel pressing equipment by an overhead crane, and the wheel pressing equipment is used to press the wheel axle 404 and the wheel cake 403.

[0034] Axle box assembly area 305 is used to install axle box 401 on the wheel pair. Here, after needing to confirm that the model and number of each assembly component are all correct, the axle box assembly workstation can be used to carry out the assembly operation of axle box 401.

[0035] The drive assembly area 306 is used to install the traction motor 405 and the gear box 402 on the wheelset to obtain the assembled bogie wheel axle drive 400. During the assembly of the traction motor 405 and the gear box 402, the assembly quality can be ensured by torque control.

[0036] The running-in test area 307 is used to perform a running-in test on the assembled bogie axle drive 400. When the assembled bogie axle drive 400 passes the running-in test, the assembled bogie axle drive 400 has completed the overhaul and can be transferred to an idle buffer area.

[0037] In the disclosed embodiment, the scattered digital information on the bogie axle drive maintenance line is integrated, summarized, analyzed and counted through the data acquisition terminal; the changes in the Internet of Things data in the bogie axle drive maintenance line simulated by the building information model can be intuitively displayed through the building information model and the display terminal, thereby helping the staff to manage and grasp the real-time production status of the maintenance line, thereby solving the problem of scattered basic data on site and lack of digital means of maintenance management, and realizing real-time, accurate and effective management of the bogie axle drive maintenance line.

[0038] Figure 5 A structural schematic diagram of a bogie axle drive maintenance line digital twin system provided by another exemplary embodiment of the present disclosure is shown. The first digital twin system 100 can be implemented based on a computer device.

[0039] like Figure 5As shown, the data acquisition terminal 101 of the first digital twin system 100 is connected to the maintenance execution management system 501 , and the Internet of Things data is sent to the data acquisition terminal 101 through the maintenance execution management system 501 .

[0040] The maintenance execution management system is a system used to manage the bogie axle drive maintenance line.

[0041] Figure 6 is a schematic diagram of the building information model, such as Figure 6 As shown, optionally, the building information model 101 is also used to simulate the physical environment of the bogie axle drive maintenance line, the staff operating on the bogie axle drive maintenance line, the first bogie axle drive being maintained on the bogie axle drive maintenance line, and the maintenance execution management system for managing the bogie axle drive maintenance line.

[0042] That is, the building information model 101 is used to simulate the bogie axle drive maintenance line in five aspects: product, equipment, personnel, environment and system, so as to simulate a virtual workshop. The product is the bogie axle drive that is maintained on the bogie axle drive maintenance line; the equipment is the multiple equipment involved in various areas of the bogie axle drive maintenance line; the personnel is the staff operating the bogie axle drive maintenance line; the environment is the physical environment of the bogie axle drive maintenance line; and the system is the maintenance execution management system 501.

[0043] Figure 7 It is a workflow diagram of building information modeling, such as Figure 7 As shown, after the data acquisition terminal 102 sends the IoT data to the building information model, the building information model 101 first performs initialization processing on the data, such as format conversion, clearing abnormal values, etc. The IoT data after initialization processing can be sent to the virtual workshop simulated by the building information model. Since the IoT data is sent in real time, the virtual workshop can also perform real-time data linkage with the equipment in the actual bogie axle drive maintenance line after receiving the data.

[0044] For example, in terms of products, the building information model 101 can simulate the full life cycle information of the bogie axle drive in real time. For example, the product's process data, quality data, work order data, etc. can be dynamically stored in the virtual product's label, accompanying the product's entire life cycle.

[0045] In terms of equipment, the building information model 101 can link the actions of multiple devices involved in various areas of the bogie axle drive maintenance line (that is, simulate the operation of the equipment in real time), and can also monitor the working status of these devices. For example, the actions, spatial positions, and operating states of various devices such as robots, AGVs, and maintenance equipment in the bogie axle drive maintenance line can be linked in real time to achieve simulation of each device.

[0046] In terms of personnel, the building information model 101 can link the actions of the staff (that is, simulate the actions of the staff in real time).

[0047] In terms of environment, the building information model 101 can analyze and monitor environmental information. For example, it can display the current maintenance environment parameter information of the workshop and the changes in the workshop environment parameters over a period of time in real time, and can issue early warnings for environmental parameters according to manufacturing process requirements.

[0048] In terms of the system, the building information model 101 can control the production process of the maintenance execution management system 101, and can also monitor the maintenance execution management system 101. For example, it can link the production plan progress, operation plan progress, process progress and other information in real time. Among them, the inventory status, logistics situation, maintenance station process, the number of products under repair and other information can also be visualized and analyzed and managed in the digital space.

[0049] Optionally, the data acquisition terminal 102 acquires data on the bogie axle drive maintenance line through a twin coding system, and the twin coding system includes: maintenance process code, maintenance component code, equipment and facility code, and building structure geographic location code.

[0050] Among them, the maintenance process coding includes coding of vehicle models, maintenance processes, storage areas, maintenance spaces, procedures, and process steps.

[0051] The overhaul component coding includes coding of axles, wheel discs, gearboxes, traction motors and axle boxes.

[0052] Equipment and facility coding includes coding the type, model, manufacturer, and department to which the equipment belongs.

[0053] The geographic location coding of building structures includes the coding of building structures in different locations, different regions and different levels.

[0054] In the twin coding system, each product component, process, equipment and building has a unique code, which exists in both the actual bogie axle drive maintenance line workshop and the virtual workshop simulated by the building information model 101. In the IoT data acquired by the building information model 101, each data corresponds to a code, which is used to indicate the source of a certain data. The building information model 101 can import each data in the IoT data into the corresponding model through the code.

[0055] Alternatively, if Figure 5 As shown, the display terminal 103 includes a primary screen, a secondary screen and a tertiary screen.

[0056] Figure 8 is a schematic diagram of the primary screen, the secondary screen and the tertiary screen, where Figure 8 Part (a) is a schematic diagram of the primary screen. Figure 8 Part (b) is a schematic diagram of the secondary screen. Figure 8 Part (c) is a schematic diagram of the three-level screen. Figure 8 Describe the display side.

[0057] like Figure 8 As shown in part (a) of FIG. 1 , the primary screen is a large screen set in various areas of the bogie axle drive maintenance line. The primary screen is used to display the building information model 101 and key performance indicators, which are driven by real-time synchronized inspection data and status data and presented in a dynamic and detailed view through the building information model 101. Workers can use this information to quickly identify potential problem areas. Here, the key performance indicators can be set according to experience, for example, some data can be selected from the status data and inspection data as key performance indicators to be displayed on the primary screen.

[0058] like Figure 8 As shown in part (b) of FIG. 1 , the secondary screen is, for example, a display screen of a plurality of workstations. The secondary screen is used to display the local structure of the building information model 101. For example, the component view of a component in the building information model 101 and the status of each part of the component (including running, faulty, normal, etc.) can be displayed. The staff can perform more specific data analysis on the secondary screen to achieve detailed fault diagnosis.

[0059] like Figure 8 The third-level screen shown in part (c) is, for example, a screen of a production scheduling center. The third-level screen is used to statistically integrate the data in the building information model 101, and can quickly query and export key data. It is a data display page that integrates, summarizes, and statistically analyzes the collected system data.

[0060] Optionally, the three-level screen can be divided into three areas: a left screen area, a middle screen area, and a right screen area according to left, middle, and right. The left screen area is used to display the maintenance execution system 501. In the left screen area, historical work orders can be selected through a filter box (filtered by work order number, time, repair process, vehicle model, abnormality, etc.) to output a list of work orders that meet the requirements.

[0061] The middle screen area is used to display the work order number currently being repaired and its corresponding process flow line and current process (distinguishing between completed and unfinished processes). Clicking a process flow can display its maintenance (historical) data in the form of a drop-down box, and the unfinished process data is empty. In other words, there is data interaction between the left screen area and the middle screen area.

[0062] The right screen area is used to display the overall overview of the building information model 101 in a bird's-eye view. After the staff selects a work order in the middle screen area, the right screen area can display the process flow line and the process position of the current wheel drive in the virtual space in the form of visual lines (for example, in the form of highlight flashing reminders), and after the staff selects the process flow in the left screen area, the right screen area can connect the visual lines to present the process flow and maintenance data in a floating window. That is, the middle screen area can control the right screen area.

[0063] The first, second and third level screens can be used to trace the completed maintenance tasks, reproduce the operation process, read and count the maintenance process data, and assist production personnel in improving maintenance processes or investigating accident processes. It can also enable staff to accurately understand the on-site maintenance operation status, track and manage the production in the area in real time, and quickly grasp the on-site situation.

[0064] Optionally, in addition to the primary screen, the secondary screen and the tertiary screen, the display terminal may also include a portable screen (not shown). The portable screen is, for example, a screen on a handheld terminal device such as a mobile phone or a tablet computer. The staff can query data from the building information model through the portable screen, and can also upload status data and detection data from field surveys through the portable screen.

[0065] Through the portable screen, on-site operation data can be quickly reported, and instant reporting and quick query of on-site data can be achieved. The summary process of maintenance record sheets is unified, which greatly reduces repetitive work. It also realizes the synchronous display of on-site personnel operation data and equipment operation data, effectively improving the efficiency of on-site information management, realizing on-site paperless operations, and improving the timeliness of on-site task feedback.
