Traditional train maintenance methods rely to a large extent on manual regular inspections and preventive maintenance strategies. Although this maintenance mode can ensure the basic operation status of trains to a certain extent, its inherent limitations are becoming increasingly prominent. Specifically, traditional train maintenance usually follows a fixed maintenance cycle. This periodic maintenance method often ignores the individual differences and dynamic changes in the actual operation process of trains, resulting in uneven distribution of maintenance resources and low efficiency. In addition, since most maintenance work is completed manually, not only is the labor intensity high, but it is also easily affected by human factors, and the possibilities of missed inspections and misjudgments are relatively high.

Detailed implementation manners

[0023] In order to enable those skilled in the art to better understand the technical solutions in the present application, the following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0024] The Internet of Things refers to connecting physical devices to the Internet through sensors, software and other technologies, enabling them to collect and exchange data. Devices can communicate in real time and make corresponding decisions or automatically execute tasks. Based on the Internet of Things technology, the present application provides a method and system for intelligent maintenance management of rail transit, which is used for the maintenance work of rail transit trains to solve the problems such as fixed maintenance cycle, low efficiency, and inability to monitor in real time in the current maintenance process of rail transit trains, improve the safety and reliability of train operation, and ensure the stable operation of the urban rail transit system.

[0025] The following will detail the method and system for intelligent maintenance management of rail transit provided by the present application with reference to the accompanying drawings.

[0026] Referring to Figure 1 as described Figure 1 is a flowchart of a method for intelligent maintenance management of rail transit provided by the embodiments of the present application.

[0027] A method for intelligent maintenance management of rail transit provided by the present application includes: S100: Based on the Internet of Things platform, obtain fault information and on-site terminal device information, and transmit them to the maintenance platform to generate a maintenance plan.

[0028] In the present application, the fault information should be understood in a broad sense, including problems found in the daily maintenance process, problems found in regular overhauls and maintenance work, and problems or abnormal states that occur during the operation of rail transit trains. The on-site terminal devices include but are not limited to intelligent material cabinets, intelligent tool cabinets, intelligent access control systems, monitoring cameras, and vehicle positioning systems. The maintenance process information includes at least one of material information, tool information, operator information, process methods, and quality inspection results.

[0029] Among them, the intelligent material cabinet is used to store and manage the materials required for maintenance, and realizes the real-time monitoring and management of the material status and usage through the Internet of Things platform. Specifically, an intelligent label shelf and an edge industrial control computer are provided in the intelligent material cabinet. A high-performance reader-writer is installed in the shelf, and RFID electronic tags are installed on the goods placed on the shelf. The reader-writer captures the tag information to identify the location and quantity of the goods, and quickly and accurately identify the goods placed on the shelf. After summarizing the goods information, the edge industrial control computer in the intelligent material cabinet sends it to the Internet of Things platform for data analysis and processing, obtains the initial data and stores it.

[0030] The intelligent tool cabinet is used to store and manage maintenance tools. Similarly, an intelligent label shelf and an edge industrial control computer are provided in the intelligent tool cabinet. After summarizing the tool information, the edge industrial control computer sends it to the Internet of Things platform to monitor the storage and usage of tools through the Internet of Things platform, ensuring the availability and maintenance of tools.

[0031] The intelligent access control system integrates a face recognition device or an IC card reader to verify the identity of employees by face recognition or reading the IC card information held by employees, and controls the opening and closing of the access control. The intelligent access control system has opened the API interface of the Http protocol. The program regularly calls the API to first query the ID list of the access control devices in the factory area, and then according to the ID, calls the API to query the access records on each access control device. Finally, the returned data is parsed and processed, encapsulated in the data format required by the Internet of Things, and sent to the Internet of Things platform via the MQTT protocol.

[0032] The monitoring camera is installed in key areas in the workshop for security monitoring, such as the raw material storage area, production line, finished product stacking area, entrance and exit, etc.

[0033] S200: Issue the maintenance plan based on the Internet of Things platform, obtain real-time maintenance process information during the execution of the maintenance plan, and monitor and adjust the execution of the maintenance plan according to the real-time maintenance process information.

[0034] Among them, the maintenance plan includes maintenance work orders, and the maintenance work orders include designated workstations, operation procedures, and quality standards. According to the real-time maintenance process information, understand the occupancy of the production line, as well as the arrangement of operators, the usage of spare parts and tools. By analyzing and processing this information, problems that may occur during the maintenance process, such as production line conflicts, improper personnel allocation, or shortage of spare parts, can be discovered and solved in a timely manner. Based on this information, reasonably formulate and execute the maintenance plan, optimize the maintenance work, so as to improve the maintenance efficiency and quality, and provide more powerful support for the production activities of the enterprise.

[0035] In some embodiments, the Internet of Things (IoT) platform is associated with at least one of a process management system, a production management system, an equipment management system, a quality management system, and a logistics management system. When formulating a maintenance plan, process documents and quality documents are associated with the maintenance plan through the IoT platform. When executing the maintenance plan, the process documents and quality documents are invoked through the IoT platform to improve the maintenance efficiency.

[0036] The IoT platform can closely associate with at least one or more of a process management system, a production management system, an equipment management system, a quality management system, and a logistics management system to form a highly integrated and collaborative working environment. During the process of formulating a maintenance plan, process documents and quality documents are associated with the maintenance plan to ensure that the maintenance work follows the established process standards and quality requirements.

[0037] Specifically, according to the fault information, the operation procedures and quality standards corresponding to the part where the fault information occurs are invoked through the IoT platform. The platform will automatically match the relevant process documents and quality documents to ensure that the maintenance work can be carried out according to the optimized plan. This not only improves the accuracy and feasibility of the maintenance plan but also greatly shortens the time for formulating the maintenance plan.

[0038] When executing the maintenance plan, the process documents and quality documents are invoked through the IoT platform to provide real-time guidance and support for the maintenance personnel. The maintenance personnel can view the relevant process parameters, quality standards, and maintenance steps through the IoT platform at any time and place, so as to ensure that the maintenance work can be carried out strictly in accordance with the established requirements. This not only improves the efficiency and quality of the maintenance work but also reduces the risks caused by improper operation or inaccurate information.

[0039] In addition, the IoT platform can also monitor the maintenance process in real time and perform data analysis to timely detect and handle potential problems. By collecting and analyzing the data during the maintenance process, the platform can objectively evaluate the effect of the maintenance work and provide strong support for subsequent improvement and optimization.

[0040] As an example, in some embodiments, the maintenance plan includes a maintenance work order, which details the maintenance tasks to be carried out, the required tools and materials, the expected completion time, and other information. Issuing the maintenance plan based on the IoT platform includes the circulation of the maintenance work order, and the circulation of the maintenance work order includes: S210: Assign the maintenance work order to the on-site terminal device at the designated work station based on the Internet of Things platform for the operator to trigger the start of the work order. The maintenance work order is the basic unit of the maintenance plan. Each work order includes information such as the process name, operation instruction manual, expected completion time, and responsible personnel, specifying the specific maintenance tasks and requirements, and is an important basis for the operator to carry out the maintenance work. By accurately assigning the maintenance work order to the corresponding work station, it can ensure that the maintenance work can proceed orderly according to the established plan, thereby improving the maintenance efficiency and quality. Specifically, set up an RFID integrated machine at the work station. Through RFID reading and writing technology and the human-machine interaction interface, the operator can interact with the device through simple operations, obtain the content of the maintenance work order from the Internet of Things platform and display it through the human-machine interaction interface, and then trigger the start of the work order through the human-machine interaction interface and feedback the start information to the Internet of Things platform. During the execution of the work order, feedback on the completion status of the process is provided for the operators and managers associated with the maintenance work order to understand the execution situation of the work order.

[0041] S220: Obtain the process documents and quality documents associated with the maintenance work order based on the Internet of Things platform for the operator to execute.

[0042] In some embodiments, the operator obtains the process documents and quality documents through the on-site RFID integrated machine via the Internet of Things platform and displays their content to guide the maintenance process and ensure the accuracy of the maintenance work.

[0043] S230: Upload the maintenance process information during the execution of the maintenance work order to the Internet of Things platform through the on-site terminal device to monitor and adjust the execution of the maintenance work order. Specifically, during the execution of the maintenance work order, the operator uploads the key information (real-time maintenance process information) during the maintenance process to the Internet of Things platform through the RFID integrated machine. The real-time maintenance process information includes at least one of material information, tool information, operator information, process method, and quality inspection result.

[0044] Among them, in terms of material information management, the Internet of Things platform can track the usage situation and remaining inventory of materials in real time according to the material information uploaded by the RFID integrated machine. This function is crucial for guiding material distribution, ensuring that the materials required for the maintenance work can be delivered to the work site in a timely and accurate manner, avoiding maintenance delays caused by material shortages, and at the same time optimizing inventory management, reducing unnecessary material backlogs and waste.

[0045] Collect and feedback operation process data in real time according to tool information to monitor whether the execution of the maintenance plan meets the operation procedures and quality standards. When operation errors occur, such as insufficient or excessive tightening torque, an alarm signal is sent to adjust the execution process of the maintenance work order; perform operation personnel scheduling according to operation personnel information to enable parallel implementation of multiple maintenance plans.

[0046] Uploading the real-time maintenance process information during the execution of the maintenance work order to the Internet of Things platform is a key step in achieving efficient monitoring and dynamic adjustment of maintenance work. This process not only improves the transparency of maintenance operations but also ensures the controllability of maintenance quality and maximizes operation efficiency. Specifically, on-site maintenance personnel use an RFID integrated machine to upload key information during the maintenance process to the Internet of Things platform in real time. This information includes, but is not limited to, material information, tool information, and operation personnel information.

[0047] In terms of material information management, the Internet of Things platform can track the usage status and remaining inventory of materials in real time based on the material information uploaded by the RFID integrated machine. This function is crucial for guiding material distribution, ensuring that the materials required for maintenance work can be delivered to the operation site in a timely and accurate manner, avoiding maintenance delays caused by material shortages, and at the same time optimizing inventory management, reducing unnecessary material backlogs and waste.

[0048] In terms of operation process data management, the Internet of Things platform obtains the parameter information of intelligent tools to monitor the maintenance process. Exemplarily, the tightening force is monitored through the torque value of an intelligent torque wrench to check whether it meets the process requirements, and the air pressure of a pressure vessel is monitored through a pressure sensor. In addition, the Internet of Things platform collects and feedbacks data during the operation process in real time, such as the usage frequency, wear degree, and operation efficiency of tools. Once a mistake or tool abnormality (such as excessive wear, improper operation, etc.) is detected during the operation process, the system will immediately send an alarm signal to prompt the operation personnel to take corresponding measures for adjustment, thereby effectively preventing the occurrence of safety accidents and ensuring the high-quality execution of the maintenance work order.

[0049] During the execution of the maintenance plan, obtain real-time maintenance process information through the Internet of Things platform, and monitor and adjust the execution status of the maintenance plan according to the real-time maintenance process information. Specifically, the Internet of Things platform also performs intelligent operation personnel scheduling based on operation personnel information, such as skill level, current location, etc., to ensure that multiple maintenance plans can be implemented in parallel without interference, improving the overall efficiency and response speed of maintenance work. For example, when a certain maintenance task requires emergency reinforcement due to special reasons, the platform can quickly identify and dispatch nearby operation personnel with corresponding skills to support, ensuring the smooth progress of the maintenance work.

[0050] Second aspect, the present application provides an intelligent maintenance management system for rail transit, which executes the above-mentioned intelligent maintenance management method for rail transit. The management system includes a collection module, an Internet of Things platform, and a maintenance platform. Among them, the collection module is installed on on-site terminal devices and is used to collect fault information, terminal device information, and real-time maintenance process information. Among them, collecting fault information includes uploading fault information through an RFID integrated machine or observing the fault location through an on-site camera, etc. The Internet of Things platform is used to receive the terminal device information and real-time maintenance process information and store them. The maintenance platform includes a maintenance plan management module and a maintenance execution management module. Among them, the maintenance plan management module calls the on-site terminal device information to generate a maintenance plan, and the maintenance execution management module executes the maintenance plan, monitors, and adjusts the execution process of the maintenance plan. The collection module and the Internet of Things platform implement data transmission based on the TCP protocol.

[0051] Among them, on-site terminal devices include but are not limited to intelligent material cabinets, intelligent tool cabinets, intelligent access control systems, monitoring cameras, and vehicle positioning systems. Through intelligent material cabinets, intelligent tool cabinets, and electronic tag shelves, precise management of materials and tools required for maintenance is realized. These devices can real-time track the inventory, usage, and location information of materials and tools, effectively avoiding the loss, waste, and misuse of materials and tools. The application of intelligent tools such as intelligent torque wrenches makes torque control during the maintenance process more precise and reliable. This not only improves the quality of maintenance work but also reduces the risk of equipment damage caused by improper operation. The configuration of intelligent access control systems and monitoring cameras strengthens the safety protection of the maintenance area. They can real-time monitor the personnel entry and exit and operation conditions in the maintenance area, promptly discover and handle potential safety hazards, and ensure the safe progress of maintenance work.

[0052] In addition, the terminal device also includes an RFID integrated machine. The RFID integrated machine set at the workstations on the production line completes data transmission with the Internet of Things platform based on the TCP protocol. Specifically, the Internet of Things platform sends a tag reading instruction to the RFID integrated machine, receives the tag information transmitted by the device, and after parsing and processing the information, reports it to the Internet of Things platform. The on-site access control system has opened an API interface of the Http protocol. The program regularly calls the API, first queries the ID list of access control devices in the factory area, and then according to the ID, calls the API again to query the access records on each access control device. Finally, the returned data is parsed and processed, encapsulated in the data format required by the Internet of Things, and sent to the Internet of Things platform using the MQTT protocol.

[0053] Data transmission between the intelligent torque wrench and the Internet of Things (IoT) platform requires obtaining the IoT platform's Appkey and Secret in advance. After logging in to the platform, a new device is created. Information such as the device name, model, ID, etc. is provided for the platform to manage and identify. The WiFi intelligent wrench is configured to connect to the IoT platform. Instructions can be sent to the device through the platform's API interface or console, and the device will perform corresponding operations according to the instructions and feedback the operation results to the platform. The program parses and processes the returned data, encapsulates it in the data format required by the IoT, and sends it to the IoT platform using the MQTT protocol.

[0054] The intelligent material and intelligent tool cabinet system has opened the API interface of the Http protocol. The program periodically calls the API to first query the ID list of intelligent materials or intelligent tool cabinets, and then according to the ID, calls the API again to query the status of each intelligent material or intelligent tool cabinet itself, and then queries the list of materials and the status of materials in the intelligent material or intelligent tool cabinet.

[0055] Finally, the returned data is parsed and processed, encapsulated in the data format required by the IoT, and sent to the IoT platform using the MQTT protocol.

[0056] In some embodiments, the rail transit intelligent maintenance management system further includes visual dashboards, which include work area dashboards, workshop dashboards, and work station dashboards, respectively set in the command center, production workshop, and on-site work stations to display maintenance process information.

[0057] There are many maintenance operators, and due to different divisions of labor, the phenomenon of untimely information transmission often occurs. Through the visual dashboards, anyone can timely understand the on-site maintenance information from the dashboards and master their own operation tasks, avoiding omissions in information transmission.

[0058] Among them, the main users of the work area dashboard are management personnel, providing them with overall statistics to assist management personnel in timely adjusting strategies and grasping the direction. The users of the workshop dashboard are relevant personnel in the on-site operation workshop, providing them with monitoring and statistical functions so that they can timely master the on-site implementation situation. The main users of the work dashboard are operators, providing them with functions such as relevant operation statistics and reminders to assist them in safe production operations and improve production operation efficiency.

[0059] In some embodiments, the system further includes a handheld mobile device, which is connected to the maintenance platform to formulate and execute a maintenance plan, and monitor and adjust the execution of the maintenance plan during the execution of the maintenance plan. Users can approve fault documents at any time and anywhere through the handheld device without relying on traditional fixed office locations.

[0060] Supports custom approval processes, and automatically pushes fault documents to corresponding approvers according to preset rules or conditions.

[0061] This application provides a method and system for intelligent maintenance management of rail transit. The acquisition module collects terminal device information and maintenance process information in real time, and the Internet of Things platform analyzes, processes, and stores this information, making the formulation of maintenance plans more scientific and reasonable. At the same time, the application of intelligent tools such as intelligent torque wrenches makes torque control during maintenance more precise, improving the quality and efficiency of maintenance work. On-site terminal devices such as intelligent material cabinets, intelligent tool cabinets, and electronic label shelves achieve precise management of materials and tools required for maintenance, avoiding the loss, waste, and misuse of materials and tools, and reducing operating costs.

[0062] It is easy to understand that those skilled in the art can combine, split, and reorganize the embodiments of this application based on several embodiments provided in this application to obtain other embodiments, and these embodiments do not exceed the protection scope of this application.
