The maintenance tasks of the non-own vehicle parts are uniformly controlled in a full-life cycle management mode, and a good foundation is laid for the subsequent enhancement of market competitiveness.
First, an overhaul process management module is introduced, wherein the overhaul process management module is configured to digitize information of an actual component structure, convert the information into basic data, establish a component configuration and an instantiated unit configuration, correlate overhaul requirements and overhaul data with the overhaul configuration, correlate operation data and overhaul history with the instantiated unit configuration, and push an overhaul flow with data to form a closed-loop system overhaul management data stream.
When a new product is delivered to a customer, basic data needs to be established for the new product in an overhaul process management module, an overhaul configuration is established, and overhaul requirements and an instantiation configuration are created.
The overhaul prediction module can calculate the time interval of the next overhaul of the component by combining the overhaul process (maintenance overhaul Cheng Jiepai, theoretical time, time upper tolerance, time lower tolerance, theoretical mileage, mileage upper tolerance and mileage lower tolerance) of the component and the operation information (current operation accumulated mileage, accumulated days, last overhaul process, last overhaul round, last overhaul accumulated mileage, last accumulated overhaul days and daily average operation mileage) of the train where the component is installed, and provides data support for purchasing material preparation and resource planning of a long period.
And the overhaul judging module is used for managing the overhaul requirements and the access types of the components, and calculating overhaul activities and plans to be carried out for the products to be repaired by using an overhaul strategy representation and judging method based on rules in the system. Taking the information of the parts to be overhauled as input, firstly obtaining overhauling parts, quantity and planning period of the parts, then calculating personalized overhauling activities of the parts through an overhauling rule judging tool, judging whether an overhauling request is reasonable or not, triggering an overhauling schedule management module if the overhauling request is reasonable, and taking a process corresponding to the overhauling requirement as an operation guide. If not, generating the part access containing the work order, and tracing the use condition of the part.
The overhaul schedule management module is used for searching all process networks under the part according to the model of the part, carrying out scheduling according to the sequence of overhaul main working procedures of the process networks and combining the maximum productivity of key working procedures, calculating the working procedure time according to the relation between the main working procedures and the working procedures, calculating the starting date of the working order through the work order of a maintenance object where the working procedure is located, arranging a responsible person corresponding to the activity, the working hour quota and the material quota according to the working procedure task list after calculating the date, generating the working order and outputting the working order, transmitting material requirement information into the SAP system, and generating purchasing requirements and executing purchasing by the SAP system. When a planner issues a plan, the overall overhaul scheduling can be summarized, and the overhaul scheduling of a single part can be adjusted according to the detail. After the preliminary planning is completed, a specific work order can be optimized to generate overhaul and production scheduling meeting the actual conditions, and an executable work order is formed.
And the overhaul process management module is used for managing overhaul processes and overhaul production, namely, carrying out standardized management on a specific overhaul activity process so as to ensure overhaul quality.
The main content of the maintenance production related module comprises maintenance team information, alternative teams, material information, material drawing numbers, evaluation types, factories, inventory, maintenance sources, factory level routes, material inventory WBS, material substitution relations, quality inspection information, quality inspection execution states, item classification, maintenance contents, maintenance standards, item point categories, maintenance methods, maintenance tool requirements, environmental requirements, measured values, procedure overhauling installation positions, historic material codes, historic manufacturers, historic production dates, component repair procedures and technical documents.

Before the production is executed, the serial number and the history are first checked, if the serial number is wrong, the maintenance object can be changed, and after the serial number is checked, maintenance producers acquire contents (product manufacturing process information and product maintenance history information) related to the work so as to assist maintenance work.
The main information in execution comprises the steps of acquiring technical documents (document numbers, document names, document catalogues, document versions and document names), acquiring tool tools according to tool requirements (tool codes, tool descriptions, tool types, tool specifications, tool types and tool numbers), checking the qualification of maintenance personnel according to personnel qualification requirements (qualification codes, qualification descriptions and qualification grades), disassembling according to operation steps, installing, performing self-checking, mutual checking and special checking according to the planning content (checking content, checking standards, quality grades, operators, measuring upper and lower limit values, measuring units, maintenance appliances and valve serial numbers).
The system records corresponding maintenance state information (operation tool, self-check/mutual check/special detection value, abnormal description) according to the maintenance result after maintenance, working time information (working time type, personnel and working time) and feeds back the execution progress in the system. And after the overhaul activity is completed, the system records the modified overhaul configuration, and closes the work order after closing all the operation steps, thereby marking that all the overhaul works are completed.
The maintenance quality inspection management module is used for taking charge of inspection planning (inspection content, inspection standard, quality grade, operators, upper and lower limit values of measurement, metering units, maintenance tools and valve serial numbers) of a maintenance process before maintenance and dynamic assembly history management (positions, procedure names, material codes, history serial numbers, history manufacturers, history production dates, disassembly and assembly serial numbers, whether scrapped pieces, whether old pieces are put in storage, overhauled dates, overhaulers, installation dates and installers) of quality inspection measurement value records (operators, upper and lower limit values of measurement, metering units and maintenance tools) and quality inspection approval processes (whether self-inspection, mutual inspection and special inspection personnel). Meanwhile, a fault management system for maintenance is established, and the fault management system comprises a fault dictionary and fault management.
Fault management is another important content in inspection quality management, including fault dictionary and fault scheme management (i.e., fault resolution process management).
The fault dictionary includes fault objects (current node, number, description), fault phenomena (pattern coding, pattern category, pattern description, source), fault causes (whether valid, reason code, reason name, reason code, reason classification, reason description, fault reason classification) and fault solutions (solution coding, solution classification, solution process solution), fault resolution process management (fault worker management), including reporting, analysis and resolution after finding a fault, and fault analysis afterwards (principal responsibility unit, other responsibility unit, final reason analysis, final handling measure, fault object, fault mode, fault solution), thereby forming a fault closed loop management.
The overhaul material management module is mainly used for solving the material management problem for the part overhaul service and has the functions of material demand planning, material warehouse-in and warehouse-out, outsourcing management, warranty period management, serial number management of materials and the like. The system monitors all system business operations (material input and output storage, material request, material acquisition and return, material maintenance result feedback and the like) related to material state transfer, accurately updates material resume table information in real time, and tracks and reversely tracks all relevant information of a specific material at each business stage in the life cycle at any time, so that guarantee is provided for material state and structure tracking.
In the aspect of the database, the system continuously uses the existing frame overhaul system database and data table structure to customize and develop new system data structures and applications, and when each module performs business processing operation, the system directly connects with the existing Oracle database to perform operations such as data adding, deleting, modifying and checking. The system can distinguish the data between different users and business categories in a data authority separation mode, and each user can only inquire and operate the data belonging to the user, so that the data security is ensured.
In the aspect of interaction between system application service and database, the logic of the existing urban rail frame overhaul system is comprehensively and detailed estimated, and the system operation efficiency is integrally improved according to optimization as required according to application conditions. Meanwhile, in the work of optimizing logic, the configurability is emphasized, and all the modification logics have good expansibility of being reversely applied to the overhaul business of the motor train unit components in the future.
