[0044] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0045] It should be noted that the following detailed descriptions are all illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

[0046] Embodiment 1:

[0047] A full-cycle control system for rail vehicle component maintenance, such as Figure 1 , Figure 2 As shown, including:

[0048] A basic information management module, configured to obtain and store basic data of rail vehicle components;

[0049] A maintenance prediction module is configured to extract the maintenance process information of the corresponding component and the vehicle operation information from the basic data, comprehensively consider the two kinds of information, and predict the time interval of the next maintenance of the component;

[0050] The maintenance judgment module is configured to receive the maintenance request of the component, find the corresponding predicted maintenance time interval, and judge whether the maintenance request is reasonable. If so, the maintenance scheduling management module is triggered, otherwise, the component usage is traced;

[0051] The maintenance scheduling management module is configured to determine the maintenance process flow and required time according to the maintenance component information in the maintenance request, arrange the maintenance time according to the maintenance department's process and time, and generate a maintenance work order;

[0052] The maintenance process management module is configured to continuously record and update the fault information, execution process information, maintenance status information and working time information of the maintenance work order until the maintenance process flow is completed;

[0053] The maintenance quality inspection management module is configured to detect and record the maintenance quality, form a quality inspection record, associate the quality inspection record with the maintenance work order, and then close the maintenance work order;

[0054] The maintenance material management module is configured to monitor and track the maintenance material and quality inspection material information involved in the maintenance work order, and update the corresponding material status based on the monitoring and tracking.

[0055] This embodiment realizes the full life cycle management of components by coordinating maintenance prediction, maintenance scheduling (planning), maintenance execution, maintenance quality inspection and Internet of Things management, avoids missed maintenance and excessive maintenance of components, improves the quality of component maintenance, and reduces the cost of component maintenance.

[0056] It can not only record the parts maintenance tasks of our company, but also perform parts maintenance for other companies. When performing parts maintenance tasks for other subsidiaries, the authority is isolated through the material serial number. The parts serial number is shipped out of other companies and entered into our company. After entering the factory, the current part’s history information can be viewed to realize data sharing of parts maintenance.

[0057] For repair tasks of parts that are not owned by the vehicle, unified management methods are adopted to achieve full coverage and control of maintenance business, laying a good foundation for subsequent enhancement of market competitiveness.

[0058] First, the maintenance process management module is introduced. The maintenance process management module is configured to digitize the information of the actual component structure and convert it into basic data, establish component configuration and instantiated unit configuration, associate maintenance requirements and maintenance data with the maintenance configuration, and associate operating data and maintenance history with the instantiated unit configuration, so as to drive the maintenance process with data and form a closed-loop system maintenance management data flow.

[0059] When a new product is delivered to a customer, it is necessary to establish basic data for it in the maintenance process management module, build a maintenance configuration, create maintenance requirements and instantiate the configuration.

[0060] The maintenance prediction module can calculate the time interval for the next maintenance of the component by combining the component maintenance cycle (maintenance cycle rhythm, theoretical time, upper time tolerance, lower time tolerance, theoretical mileage, upper mileage tolerance, lower mileage tolerance) and the operation information of the train where the component is installed (current cumulative running mileage, cumulative number of days, last maintenance cycle, last maintenance round, last cumulative mileage, last cumulative maintenance days, average daily running mileage), thereby providing data support for long-term procurement and material preparation and resource planning.

[0061] The maintenance judgment module is used to manage component maintenance requirements and component access types; it uses the rule-based maintenance strategy representation and judgment method in the system to calculate the maintenance activities and plans required for the product to be repaired. Taking the information of the component to be repaired as input, first obtain the maintenance component, quantity and planned cycle of the component, and then calculate the personalized maintenance activities of the component through the maintenance procedure judgment tool to determine whether the maintenance request is reasonable. If it is reasonable, the maintenance scheduling management module is triggered, and the process corresponding to the maintenance requirement is used as the operation guide. If it is unreasonable, a component access containing a work order is generated to trace the use of the component.

[0062] The maintenance scheduling management module is used to find all process networks under the component according to the component model, and schedule the production according to the sequence of the main maintenance processes of the process network, combined with the maximum capacity of the key processes, and the time of the main process of the system. Then, according to the relationship between the main process and the process, the system calculates the time of the process, and then calculates the start date of the work order through the work order of the maintenance object where the process is located. After calculating the date, according to the process task list, arrange the person in charge, labor time quota and material quota corresponding to the activity, generate and output the work order, and pass the material demand information to the SAP system, which generates procurement requirements and executes procurement. When the planner issues the plan, he can summarize and issue the overall maintenance schedule, or adjust the maintenance schedule of a single component according to the details. After completing the preliminary plan, a specific work order can be optimized to generate a maintenance schedule that meets the actual situation and form an executable work order.

[0063] The maintenance process management module is used to manage maintenance processes and maintenance production, that is, to implement standardized management of specific maintenance activity processes to ensure maintenance quality.

[0064] The maintenance production related modules are driven by the issued work process instructions, and the main contents include: maintenance team information, alternative teams, material information, material drawing number, evaluation type, factory, inventory, maintenance source, factory-level route, material inventory WBS, material substitution relationship, quality inspection information, quality inspection execution status, project classification, maintenance content, maintenance standards, item category, maintenance method, maintenance tool requirements, environmental requirements, measurement values, process disassembly and installation location, history material code, history manufacturer, history production date, component repair process, and technical documents.

[0065] In other embodiments, the above contents may be modified.

[0066] The team execution personnel collect materials according to the material requirements in the operation process guide, and perform maintenance according to the standard procedures in the operation process guide. Before production execution, the serial number and history must be confirmed first. If they are wrong, the maintenance object can be changed. After confirmation, the maintenance production personnel obtain work-related content (product manufacturing process information and product maintenance history information) to assist in maintenance work.

[0067] The main information during execution includes: obtaining technical documents (document number, document name, document directory, document version, file name), collecting tools and tools according to tool and tooling requirements (tool code, tool description, tool type, tool specifications, tool model, tool quantity), checking the qualifications of maintenance personnel according to personnel qualification requirements (qualification code, qualification description, qualification level), disassembly and installation according to operating procedures, and conducting self-inspection, mutual inspection, and special inspection according to the quality inspection planning content (inspection content, inspection standard, quality level, operator, upper and lower limits of measurement, unit of measurement, maintenance equipment, valve serial number).

[0068] After the maintenance, the system records the corresponding maintenance status information (operating tools, self-inspection / mutual inspection / special inspection values, abnormal descriptions), working time information (type of working hours, personnel, working hours) according to the maintenance results, and feedbacks the execution progress in the system. After the maintenance activity is completed, the system records the changed maintenance configuration, and closes the work order after closing all operation steps, thus marking the completion of all maintenance work.

[0069] The maintenance quality inspection management module is responsible for the inspection planning of the maintenance process before maintenance (inspection content, inspection standards, quality level, operator, upper and lower limits of measurement, measurement unit, maintenance equipment, valve serial number), and dynamic assembly history management during the maintenance process (position, process name, material code, history serial number, history manufacturer, history production date, disassembly and installation serial number, whether it is scrapped, whether the old parts are put into storage, disassembly date, disassembly person, installation date, installer), quality inspection value records (operator, upper and lower limits of measurement, measurement unit, maintenance equipment), quality inspection approval process (whether self-inspection, whether mutual inspection, special inspection personnel). At the same time, a maintenance fault management system is established, including a fault dictionary and fault management.

[0070] Fault management is another important part of maintenance quality inspection management, including fault dictionary and fault solution management (i.e. fault resolution process management).

[0071] The fault dictionary includes fault object (current node, number, description), fault phenomenon (mode code, mode category, mode description, source), fault cause (whether valid, cause code, cause name, cause code, cause classification, cause description, fault cause classification) and fault solution (solution code, solution description, solution classification, solution process plan); fault resolution process management (fault work order management), including reporting, analysis and resolution after the fault is discovered, as well as post-fault analysis (main responsible unit, other responsible units, final cause analysis, final handling measures, fault object, fault mode, fault plan), thereby forming a closed-loop fault management.

[0072] The maintenance material management module is mainly used to solve material management problems for component maintenance business, and has functions such as material demand planning, material warehousing, outsourcing management, warranty period management, and material serial number management. It monitors all system business operations related to material status transfer (material warehousing, material request, material acquisition and return, material maintenance result feedback, etc.), updates material resume information in real time and accurately, and forward and reversely tracks all relevant information of specific materials at each business stage in their life cycle at any time, ultimately providing guarantee for material status and structure tracking.

[0073] In terms of database, the system continues to use the existing overhaul system database and data table structure, customizes and develops new system data structure and applications, and directly connects to the existing Oracle database to perform operations such as adding, deleting, modifying and checking data when each module performs business processing operations. The system will distinguish data between different users and business categories by separating data permissions. Each user can only query and operate his own data to ensure data security.

[0074] In terms of system application services and database interaction, a comprehensive and detailed evaluation of the existing urban rail overhaul system logic is conducted, and optimization is performed on demand according to application conditions to improve the overall system operation efficiency. At the same time, in the optimization of logic, configurability is emphasized, and all modified logics have good scalability for reverse application to EMU component maintenance business in the future.
