[0002] Traditional bogie replacement systems are completed using a boom-type bogie jacking line. The train is parked on the maintenance track bridge, and the entire train body is lifted using the boom-type bogie jacking line. The mechanical connection between the faulty bogie and the car body is manually disconnected before the new bogie is installed. This method is inefficient and has a low degree of automation. Furthermore, while the aforementioned automated bogie replacement systems typically automate mechanical movements, they only use basic PLC control units and lack equipment status monitoring, information exchange and transmission, and safety monitoring and early warning functions. The digitization, intelligence, and visualization of the replacement equipment are insufficient, resulting in weak comprehensive management and control capabilities. Summary of the Invention

[0025] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention. Furthermore, the technical features involved in the various embodiments of this invention described below can be combined with each other as long as they do not conflict with each other.

[0026] The terms "first," "second," "third," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish different objects, not to describe a specific order. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or apparatus that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to these processes, methods, products, or apparatuses.

[0027] The first embodiment of the present invention proposes an automatic bogie replacement management system for rail transit trains, which includes, for example, a replacement process control subsystem, a replacement data monitoring subsystem, and an information interaction subsystem.

[0028] The bogie replacement process control subsystem is used to construct a digital visualization model of the operators and tools through intelligent devices, thereby guiding and controlling the on-site bogie replacement process. Furthermore, the intelligent devices are wearable devices equipped with operator behavior recognition, work scenario visualization, work guidance, and safety protection functions.

[0029] Specifically, the smart devices mentioned include smart gloves, smart helmets, smart work clothes, and smart headsets worn by on-site workers. The smart helmets can connect to the other devices and act as a central control unit. Workers receive guidance from the work instruction system through the smart headsets. During operation, sensors connected to the smart gloves and smart work clothes monitor the operator's steps through a behavior recognition system. At the same time, the smart helmet displays a virtual device model showing the current bogie assembly / disassembly status.

[0030] The bogie replacement data monitoring subsystem is used to collect safety operation monitoring data of relevant physical equipment during the bogie replacement process, based on the characteristics of the bogie replacement scenario. Specifically, the subsystem collects information such as sound, light, temperature, electricity, and heat from physical equipment through the data acquisition layer of IoT sensing technology. Video cameras and infrared PTZ cameras are used to monitor the factory interior and the replacement system; fire monitoring devices collect smoke information through smoke alarms; displacement sensors are installed in the foundation pit unit of the replacement system to monitor foundation pit settlement; infrared sensors are used to monitor train parking positions and for marking work areas; stress and strain sensors monitor the stress on the replacement equipment. All data is processed and stored by the data acquisition host. Furthermore, the collected data is transmitted via network cable or wireless AP to the virtual factory BIM model and MES system. The BIM model and MES system are updated with real-time data information, achieving real-time linkage between the physical world and the virtual model.

[0031] The information interaction subsystem includes a condition acquisition module and a communication module corresponding to each bogie replacement device, used to achieve real-time exchange of condition information between the bogie replacement devices in different replacement processes. Furthermore, the information interaction transmission system installs sensors on each bogie replacement device. The collected data is transmitted to a switch via network cable and a wireless access point (AP). The switch then transmits the information to a 5G communication module via the wireless AP. The 5G communication modules of each device are interconnected via the 5G frequency band to achieve information interaction and transmission functions. All 5G communication modules are controlled by the AC controller via the wireless AP.

[0032] Furthermore, the automatic bogie replacement management system for rail transit trains also includes an equipment self-inspection subsystem, which performs the equipment self-inspection method in the following three steps: Step S1: After the bogie replacement conditions are met, obtain the self-inspection command of the motor; Step S2: Unlock each replacement device, control all motors to rotate at idle speed, and activate the sensors; Step S3: Determine the health status of the motor and transmission system based on the sensor data.

[0033] Furthermore, the automatic bogie replacement management system for rail transit trains also includes, for example, a safety status monitoring subsystem. This subsystem comprises a data sensing module, a data processing module, a data analysis module, and a safety evaluation module. The data sensing module, for example, uses fiber optic grating sensors deployed on the bogie assembly / disassembly equipment to monitor the real-time stress on the equipment during operation; pressure sensors are deployed at load-bearing platform support points to monitor the stress at each point and prevent unbalanced stress states when carrying heavy loads; and displacement sensors are deployed within the foundation pit unit to monitor foundation settlement. The collected data signals are processed and analyzed by the data processing module and then uploaded to the safety evaluation module via the data transmission module for intelligent diagnostic decision-making.

[0034] Furthermore, the automatic bogie replacement management system for rail transit trains also includes, for example, an equipment safety early warning subsystem. This subsystem includes, for example, laser sensors installed in the maintenance depot to monitor personnel intrusion into hazardous areas and foreign object intrusion into the work area; pressure sensors to monitor the operating status of load-bearing equipment within the bogie replacement equipment and to monitor for abnormal pressure conditions; displacement sensors to monitor foundation settlement in the pit unit; fiber optic grating sensors to monitor for fire and smoke; and acoustic sensors installed above the maintenance depot to monitor for abnormal sounds within the depot. All sensors transmit signals to the terminal control system, which then sends commands to the alarm devices to implement the alarm function.

[0035] Furthermore, the automatic bogie replacement management system for rail transit trains also includes, for example, a remote guidance subsystem. This subsystem provides remote guidance for maintenance when a malfunction occurs in the bogie replacement system. The system uses a communication module for remote communication. During communication, experts use an AR (Anti-Fault Marking) module to mark potential fault locations and use the remote guidance module to guide on-site personnel in maintenance and bogie replacement through sound and images. The maintenance and replacement results, along with the AR-marked areas, are recorded in the management module. Simultaneously, the historical records in the management module can provide prior information for identifying fault points.

[0036] In summary, the automatic bogie replacement management system for rail transit trains proposed in this embodiment of the invention guides and controls the on-site bogie replacement process by constructing a digital visualization model of operators and tools using intelligent devices. Based on the characteristics of the bogie replacement scenario, corresponding sensors are set up to collect operational data from relevant physical equipment, enabling real-time monitoring of equipment operating conditions and operator movements. Furthermore, it manages and interacts with comprehensive equipment information, allowing for interconnectivity between devices and effectively improving bogie replacement efficiency and safety during the replacement process. It also provides safety status and early warning monitoring for each bogie replacement device, such as fatigue monitoring of the gantry crane's own structure and other safety features. The system monitors the balance of the moving track bridge, the structural reliability of the mobile lifting trolley platform, and the settlement of the foundation pit unit, and provides timely warnings of dangerous situations. This significantly improves the monitoring and management capabilities during bogie replacement, further ensuring operational safety. A corresponding virtual digital model is established based on the monitoring information of the physical equipment, allowing for real-time visualization of the automatic bogie replacement process, facilitating comprehensive monitoring by management personnel. For difficult-to-solve faults, AR technology is used, and remote expert guidance is provided via mobile devices such as smartphones and tablets to complete the work. This highly digitalized and reliable system provides strong support for the intelligent operation and maintenance of bogie replacement equipment.
