Description

Technical Field

[0001] The present invention relates to the field of simulation software architecture design and remote fault diagnosis, and particularly to a remote fault diagnosis system based on the simulation software architecture design of a project plan. Background Art

[0002] Currently, when building a new project (engineering or system), it is first necessary to carry out a plan design, the main contents of which include design requirement analysis, system function analysis, technical means analysis, implementation progress analysis, acceptance method analysis, etc. Traditional design plans are based on experience summary, using empirical formulas, charts, and design manuals formed by mechanics and mathematics as the design basis, characterized by static passive analysis, approximate calculation, empirical design, and manual labor, and repeatedly communicate and rectify with users.

[0003] Secondly, after the project is delivered, to ensure the normal operation of the system, it is necessary to detect or predict system faults and take corresponding measures to repair the faults on this basis. The three stages of diagnosis include fault detection, fault isolation, and fault identification. Fault detection methods mainly include offline manual detection, single-machine centralized detection, local area network distributed detection, and Internet remote detection, etc. Most of the current market fault diagnoses adopt on-site distributed detection.

[0004] The following problems are brought about by traditional plan design and traditional detection methods: (1) It is impossible to deeply understand user requirements, and it is necessary to repeatedly communicate and rectify the plan, consuming a lot of time and energy; (2) The design lacks novelty and features, and the design needs to be continuously improved; (3) After the design is completed, the detection method is not perfect and the effect cannot be effectively predicted; (4) On-site distributed detection is vulnerable to human factors, geographical environment, technical conditions, and cannot be monitored in real time; (5) It is impossible to make full use of information databases and manufacturer technical support. Especially for the diagnosis of complex systems, it takes more time and economic costs.

[0005] Therefore, it is necessary to construct a reasonable and highly adaptable simulation software architecture that can directly apply the plan design to the simulation software, with the help of new technical means, based on the whole, integrate system functions with beautiful interfaces, effectively reduce investment risks and safety risks, reduce research time, and improve the efficiency and quality of plan design. By collecting real-time status information of equipment operation through monitoring points on the equipment, establishing a remote service platform, and using remote fault diagnosis methods for monitoring, faults can be detected in a timely manner, equipment repair time can be shortened, cost consumption can be reduced, the degree of system automation can be improved, and economic benefits can be enhanced.

[0062] Embodiment 1: A design solution developed based on the Linux platform for the simulation architecture of the present invention mainly includes: a requirements analysis module, an overall design module, a detailed design module, a solution simulation module, a system function module, and an information feedback module. The analysis data obtained by the requirements analysis module is implemented into the overall design; the overall layout of the overall design module is specifically implemented by the detailed design module; whether the detailed design module meets the user requirements is verified by the solution simulation module; the result data of the solution simulation is displayed by the system function module; after the system function is inspected by the user and relevant personnel, the data is transmitted to the requirements analysis module through the information feedback module to rectify the solution.

[0063] This simulation architecture can separate the functional software from the data. With the help of simulation technology, it integrates the system function with the aesthetic appearance of the interface, deeply understands the user requirements through feedback opinions, effectively reduces the number of communications, shortens the development time, and improves the efficiency and quality of solution design.

[0064] The requirements analysis module is a functional module in which developers conduct in-depth and meticulous research and analysis, accurately understand the requirements of users and projects for functions, performance, reliability, etc., conduct analysis and sorting, and form a complete, clear, and standardized document, including functional requirements, non-functional requirements, and design constraints, etc. The work in the requirements analysis stage is divided into problem identification, analysis and synthesis, specification formulation, and review. The data and specification documents obtained through the requirements analysis module are the guiding principles for the overall design module.

[0065] The overall design module is a general design of global problems and also the composition and layout of system design, divided into software overall design and hardware overall design. The former includes computer configuration design, system module structure design, database design, code design, and system reliability design, etc.; the latter includes hardware selection, hardware arrangement, hardware interface, hardware installation, and environmental requirements, etc., which is the basis for the detailed design module and determines the overall architecture, main performance parameters, technical indicators, appearance, and cost of the system.

[0066] The detailed design module is a further refinement of the overall design module, which transforms the functional description into an accurate and structured process description. It mainly includes software interface design, implementation of specific module functions, such as model disassembly and assembly, operation process, power-on operation, and fault diagnosis, the specific models of the selected hardware, interfaces, spatial arrangement positions, connection methods between hardware, required power supply models, etc. The detailed design module directly affects the implementation of the scheme simulation and the simulation results.

[0067] Scheme simulation is a direct test of whether the detailed design module is reasonable and can meet the expected requirements.

[0068] The system function module is the effect display of the simulation module. It feeds back the requirements to the requirements analysis module at one time through the information feedback module, revises the overall design, and improves the efficiency and quality of the scheme design.

[0069] The remote fault diagnosis of the present invention is a remote diagnosis system based on the browser / server (B / S) architecture, mainly including: a client module, a network server module, a database server module, and a diagnostic expert system, etc. The client is responsible for data acquisition and processing, and handling the interaction with users. The user accesses the network server of the remote diagnosis center through the unified address URL of the browser to transmit the collected data file. The network server is the business logic processing center of the whole system. It can respond to the collected data files sent by multiple users, start the inference engine of the expert diagnosis system for diagnosis. The diagnostic inference engine obtains the fault analysis results and maintenance suggestions according to the corresponding knowledge base and fault diagnosis rules. Finally, the network server organizes the fault analysis results and maintenance suggestions into an HTML page for the user to download and view. The database server responds to the database requests from the network server and manages the definition, maintenance, access, and update of data.

[0070] This structure can realize network resource sharing, form a rich diagnostic database and diagnostic knowledge base, and has openness and flexibility; it can realize remote collaborative diagnosis of a multi-diagnosis system with human-machine cohabitation, and improve the overall diagnostic ability; the software system development is independent, which is convenient for system design, production, operation, and round-the-clock uninterrupted maintenance.

[0071] The simulation software architecture design of the present invention is based on the Linux technology platform. According to the different needs of different users, different design schemes and the arrangement positions of hardware are generated for 3D modeling and simulation, giving users an intuitive display and experience. According to the user feedback, the scheme design is adjusted in time to finally adapt to the user's needs. The simulation scheme design can effectively reduce the number of repeated communications with users, avoid wasting a lot of time and energy, and improve economic benefits.

[0072] After the system is set up, to ensure its stable operation, it is necessary to conduct real-time detection of the system to promptly discover and eliminate faults. By leveraging the advantages of network information technology and based on diagnostic resources and expert systems, a remote fault diagnosis system is adopted for diagnosis. In this way, users can remotely repair and regulate faults occurring in multiple remote systems without having to reach the site, which facilitates centralized management by users and improves the stability, effectiveness, and economy of the system.

[0074] The requirements analysis module mainly investigates the user's requirements for the functions, performance, reliability, etc. of the project, analyzes and organizes them, and forms a complete, clear, and standardized document. The general design module is the overall layout of the project design, which realizes module division, interface design, database design, and hardware selection and arrangement, and determines the overall architecture, main performance parameters, technical indicators, appearance, and cost of the project. The detailed design module is a refinement of the general design. Based on the module division of the general design, it realizes the algorithm design of each module, the user interface design, the refined design of the data structure, and the selection of specific hardware models and interfaces. The scheme simulation module migrates the scheme design to the simulation software and conducts simulation experiments according to the operation process. The system function module shows through simulation whether the scheme design meets the user's requirements and presets the function implementation status. The information feedback module belongs to the data transmission level and feeds back the experimental simulation data and user opinions to the requirements analysis module to rectify the scheme.

[0075] Refer to the appendix Figure 2 As shown, the remote diagnosis system based on the B / S architecture is divided into four layers, specifically including: a client module, a network server module, a database server module, and a diagnostic expert system, etc. The client module belongs to the user level and is responsible for collecting the status information of the operating equipment, analyzing and processing it, and uploading the processed data in a packaged form to the network server of the remote diagnosis center linked by the unified address URL of the browser. The network server module belongs to the application level and is the business logic processing center of the diagnosis system. It responds to the collected data file and starts the inference engine of the expert diagnosis system for diagnosis. The database server module belongs to the database level and responds to the database requests of the network server and manages the definition, maintenance, access, and update of data. The diagnostic expert system belongs to the knowledge base level and is the soul of the remote diagnosis center. According to the corresponding knowledge base and fault diagnosis rules, it obtains the fault analysis results and maintenance suggestions and transmits the data to the network server module.
