Description

Technical Field

[0001] The present invention relates to the technical field of solid rocket engines, and in particular to a solid rocket engine resume management system and method. Background Art

[0002] The solid rocket engine resume management system is one of the important technical means to ensure the comprehensive support and use of solid rocket engines throughout their life cycle. In modern warfare, especially informatized warfare, all branches of the armed forces are involved, weapons and equipment are of many types, consumption is high, and the war damage rate is high, and there is a strong dependence on equipment support. In a sense, military confrontation has evolved to a certain extent into a confrontation between comprehensive support systems for weapons and equipment. In recent years, with the increase in model design tasks and the continuous development of digitalization of weapons and equipment, in order to ensure that model missile engines meet user needs and overall missile requirements, it is necessary to apply a new generation of development methods, tools and means to ensure the delivery and after-sales service of a new generation of solid engines.

[0003] As the requirements for quality and efficiency of weapons and equipment development become increasingly stringent, my country's military enterprises in aviation, aerospace, shipbuilding and other fields that have applied digital technology have carried out research on product comprehensive support technology since 2000. Domestically, represented by Jinhang Digital, it has taken the lead in comprehensive support in the field of domestic digital military industry and established a relatively complete and mature comprehensive support service system. The construction and application of digital comprehensive support related projects (IETM, visual maintenance equipment, etc.) have been carried out at different levels, especially in the research and development of special information systems and special IT tools for overall after-sales service technology of weapons. To a certain extent, it has promoted the integration of weapon equipment design and comprehensive support.

[0004] At present, there are many problems in the comprehensive guarantee of engine after-sales service, such as backward engine after-sales service guarantee model, lack of digital management methods for after-sales service, lack of data recording means for on-site technical support, and difficulty in review due to lack of electronic resume management methods. On the one hand, these problems seriously hinder the rapid development of information technology and digital technology for comprehensive guarantee of after-sales service of solid rocket engines. On the other hand, they lead to low quality of after-sales service of solid rocket engines and inability to guarantee working reliability. Summary of the invention

[0005] The present invention proposes a solid rocket engine resume management system and method to solve the problems of obvious record loss and insufficient management in the current after-sales service guarantee, and the inability to ensure work reliability.

[0006] In order to solve the above-mentioned technical problems, one of the objects of the present invention is to provide a solid rocket engine record management method, which collects engine maintenance record data through information technology, manages and updates the record according to mission requirements, and realizes rapid tracing of engine record information. Through information system construction, an engine maintenance record library and a technical maintenance record library are constructed to optimize the management of solid rocket engine record information. According to the engine maintenance management method, an engine maintenance information management method is constructed. According to the technical requirements of the model, a maintenance plan is generated regularly to realize early warning and reminder management of products that need maintenance, so as to facilitate the preparation of maintenance resources and the preparation and issuance of maintenance plans in advance.

[0007] Further, the method comprises:

[0008] Establish an engine factory product library, strengthen the management of delivered products, and reconstruct the product composition from the perspective of after-sales service based on the EBOM in the PDM system to form an SBOM. Push the basic information and structural information of engine products, component history data, product data packages, and structured technical data and required maintenance resources of the IETM system from the production support management system through the integrated interface, and associate the SBOM to form the engine maintenance BOM.

[0009] Generate products and plans that need to be refurbished annually or regularly according to model requirements, issue early warnings and statistical reminders for related work through the system homepage, fill out after-sales service notices in the digital service guarantee system based on user feedback or annual plans, form maintenance plans or training plans and push them to the ERP system, and carry out spare parts planning and production management in advance according to spare parts production cycle;

[0010] After the maintenance plan or training plan is reviewed and approved, and the task is assigned and executed, fill in the technical service notification form, as well as technical escort service information, maintenance information, replacement of components, maintenance records and other information to form an electronic record of engine maintenance, and automatically associate it with the engine components. According to the information of the replaced components, update the current status of the engine components, push the maintenance quality summary report and escort flight report to the PDM system, and push the maintenance record and technical escort record to the generated guarantee management system. Push the engine record information and after-sales maintenance information to the technical data analysis software, and then fill in the product after-sales service report. After the training plan is executed, fill in the training record, register the instructor and trainee information, upload the training materials, etc. Finally, fill in the spare parts consumption registration and update the spare parts ledger;

[0011] Select a maintenance plan or training plan, complete a user satisfaction survey, and send completion information to the ERP system.

[0012] Furthermore, the filled-in information includes: technical service notification form, technical escort service information, maintenance information, replacement component status and maintenance records.

[0013] Furthermore, the SBOM management is specifically as follows: SBOM is based on EBOM and adjusted according to after-sales guarantee requirements. SBOM management is a product configuration tree organized by the after-sales service business department according to the needs of product repair and maintenance and according to the usage and maintenance methods. The data basis of SBOM is the design BOM in the PDM system, which is created through the PDM system interface. After the data in the PDM system is finalized, business personnel can query the product finalization baseline of the specified batch through the integrated interface. After the baseline is selected, the system interface will automatically transfer the data in PDM to the digital service guarantee system for data reconstruction to form the tree structure of SBOM.

[0014] Furthermore, the engine information includes basic information of the engine product, structural division and delivery history information of the product. The basic information and structural information of the product are pushed from the production support management system through the integrated interface. The delivery history information of the engine product is generated by pushing from the production support management system through the integrated interface. The specific operation of the engine product management is as follows:

[0015] 1) Engine management displays the engine information list as follows. The system should support the query, creation and batch import of engine factory history data, filter and export engine records according to different query conditions, and display the hierarchical structure of engine products in the form of a structure tree;

[0016] 2) Create new engine information and engine product delivery history information through the page method. To manually create engine information, first select SBOM data, create product BOM, and edit and save the engine product BOM pushed from the production support management system through the integrated interface. The page for adding or editing engine information and engine product delivery history information is as follows, and can be generated through offline Excel import.

[0017] Furthermore, the maintenance plan management is specifically as follows:

[0018] 1) Creation of after-sales service notifications. After receiving official notifications from superior authorities and customer service, scientific research and production management personnel create product after-sales service work notifications in the digital service guarantee system and create maintenance plans based on the product after-sales service work notifications. One after-sales service work notification can be associated with one or more after-sales service plans;

[0019] 2) The unified entry point for maintenance plans and technical support plans is the after-sales service work notice. Research and production management personnel first select the after-sales service work notice in the digital service support system, and then create an after-sales service plan. An after-sales service work notice can be associated with one or more after-sales service plans. At the same time, the system pushes the plan agent tasks to the unified information integration portal based on the person in charge and ID number of the plan, and finally sends the after-sales service plan to the ERP system;

[0020] The system supports early warning of after-sales service plans on the system homepage based on the planned start time and completion time.

[0021] Furthermore, during the service life, the equipment will undergo multiple repairs, modifications, refits, and technical upgrades. During this process, a large amount of equipment or device maintenance, installation, and disassembly information will be generated. The management of engine maintenance history is an important basis for managing and tracing the technical status of equipment. The maintenance management is specifically as follows:

[0022] 1) Creation of technical service (production follow-up) record sheets. After completing the service support tasks, the service support personnel fill out the technical service record sheets in the system. The replacement component status, maintenance records, and technical support information will be automatically associated with the engine components. At the same time, the status of the current engine components will be updated according to the information of the replaced components.

[0023] 2) Product after-sales service report. After completing the external service guarantee task, the service support personnel will fill in the product after-sales service report in the system. The replacement component status, maintenance records, and technical support information will be automatically associated with the engine component. At the same time, the status of the current engine component will be updated based on the information of the replaced component.

[0024] Based on the same inventive concept, the present invention also provides a solid rocket engine record management system, including two functional modules: service guarantee business management and maintenance support management. The digital service guarantee system based on this function realizes the acquisition of basic information and data update linkage, realizes information sharing and business process coordination between digital service guarantee software and other systems, and improves management efficiency and service quality.

[0025] Furthermore, the digital service support system integrates the ERP system, PDM system, IETM system, generation support management system, solid engine basic data analysis and application software, and unified information integration portal through interfaces.

[0026] The above one or more technical solutions of the present invention have at least one or more of the following technical effects:

[0027] The present invention relates to a solid rocket engine history management method, which can realize the digital management of engine product history data. The present invention can be used as a comprehensive guarantee method for the entire life cycle of the engine. Compared with the existing method, it improves the digital service guarantee capability of the engine and reduces the management difficulty of product delivery and after-sales service maintenance.

[0028] Compared with the existing technical solutions, the solid rocket engine history management method of the present invention improves the digital service level of the engine throughout its life cycle, and transforms the traditional offline decentralized management based on the functional division of military units into a unified and centralized information management method based on an information platform, which is of great significance for filling the gaps in digital after-sales service and comprehensive guarantee of the engine.
