Description

Technical Field

[0001] The present invention relates to the technical field of equipment maintenance, and in particular to a RCM analysis method and equipment based on auxiliary function analysis optimization. Background Art

[0002] In RCM (Reliability-Centered Maintenance, RCM for short), the first and most important step is to write the main functions and auxiliary functions. The main function is the reason for the existence of the product and is easy to write, but the auxiliary functions involve various needs and are easy to be omitted during the analysis process. Therefore, in RCM analysis, a special parallel classification of ESCAPES (environmental integrity, protection, safety and economy, control, efficiency, inclusion, appearance, redundancy, comfort, corresponding to English as Environmental integrity, Safety / structural integrity, Control / containment / comfort, Appearance, Protection, Economy / efficiency, Superfluous functions) is provided for analysis guidance.

[0003] However, the parallel categories of ESCAPES are not mutually exclusive at the same level, but a hierarchical relationship between the demand level class and the implementation level class functions. For example, containing SF6 decomposition products is a requirement of the safety / environmental protection class implemented by the containment class function; controlling the temperature of the transformer insulating oil is a requirement of the economy class implemented by the control class function. Placing the demand class function and the implementation class function in parallel at the same level cannot reflect the logical relationship between the functional dimensions of ESCAPES and the fact that specific functions (such as containing SF6 decomposition products and controlling the temperature of the transformer insulating oil) can only be placed in the implementation class function (containment, control) or the demand class function class (safety / environmental protection, economy). Moreover, the dimensional division of the implementation class function of ESCAPES is more suitable for product function analysis directly related to users, and is not very instructive in the auxiliary function writing of production enterprises such as power transmission and distribution systems (for example, display / control / alarm / trip is a typical implementation class function in the power transmission and distribution scenario, but ESCAPES does not have a display / alarm / trip function dimension; there is no demand class function dimension for operation and maintenance in ESCAPES; the comfortable implementation class function in ESCAPES is poorly applicable to non-manual production scenarios. Summary of the invention

[0004] The technical problem to be solved by the present invention is that the existing auxiliary function classification method analysis cannot effectively guide production enterprises to perform auxiliary function analysis of RCM.

DETAILED DESCRIPTION

[0017] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, specific embodiments of the present invention are now described in detail with reference to the accompanying drawings.

[0018] In the following description, specific details such as specific system structures, technologies, etc. are provided for the purpose of illustration rather than limitation, so as to provide a thorough understanding of the embodiments of the present invention. However, it should be clear to those skilled in the art that the present invention may be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to prevent unnecessary details from obstructing the description of the present invention.

[0019] An embodiment of the present invention provides an RCM analysis method based on auxiliary function optimization, such as Figure 1 As shown, the RCM analysis method based on auxiliary function optimization includes the following steps: S10: Acquire the function information file of the target system analyzed by RCM.

[0020] Optionally, the systems to be analyzed are screened and the target systems are determined based on the analysis period and the complexity of the systems to be analyzed. Exemplarily, the analysis period refers to the time required to complete the RCM analysis. In this example, RCM analysis is a systematic and detailed process, including steps such as functional analysis, failure mode analysis, and maintenance strategy formulation. Therefore, it is necessary to evaluate which systems can be analyzed within the limited period when the project time is limited. Exemplarily, the systems to be analyzed refer to all equipment or systems planned for RCM analysis. Optionally, the systems to be analyzed include mechanical systems / equipment, electrical systems / equipment, instrument systems / equipment, etc. In this example, the systems to be analyzed are screened and the target systems are determined by analyzing the period and the complexity of the systems to be analyzed, so that in the RCM analysis, according to the period required for the analysis and the complexity of the system, the target systems with high priority and suitable for analysis are selected to ensure the efficiency and effectiveness of the analysis work.

[0021] Furthermore, the functional information files of the target system include but are not limited to technical files, reliability data files, maintenance and repair files, safety and environmental files, standards and guidelines related to the target system.

[0022] S20: Determine the main functions of the target system according to the function information file.

[0023] Optionally, keyword extraction technology is used to extract the functional description and key performance indicators of the device from the functional information file, and then the main functions are determined according to the design purpose and expected use of the target system. Exemplarily, the device functions and performance data are extracted from the functional information file, and then the main functions of the device are clarified in combination with the design goals and actual uses of the device, so as to focus on the key parts in the analysis, avoid resource waste, and ensure that the analysis results have higher accuracy.

[0024] S30: Generate auxiliary functions of the target system according to the function information file.

[0025] Specifically, after extracting the functional description and key performance indicators of the device from the functional information file using keyword extraction technology, all device functions of the device are determined, the main function determined in step S20 is removed from all device functions, and the functions that need to be implemented in conjunction with the main functions are screened out to generate auxiliary functions of the target system. That is, the auxiliary functions include other device functions other than the main functions removed from the functional information file, as well as device functions used to implement the main functions in other aspects. Furthermore, the device functions implemented in conjunction with the main functions are analyzed and listed from six aspects: safety / environmental protection, production, economy, operation and maintenance, management, and others.

[0026] S40: Perform fault management analysis on main functions and auxiliary functions to obtain target system analysis guidelines.

[0027] Specifically, identify the potential failure modes, effects, and causes of each auxiliary function and main function, and conduct risk assessment. Based on these analyses, formulate preventive and corrective measures, and integrate all this information to generate target system analysis guidelines.

[0028] The present invention obtains auxiliary functions through main functions and function information files, and deduces auxiliary functions according to the logical relationship between auxiliary functions and main functions and devices, thereby ensuring the integrity and standardization of auxiliary functions and improving the quality and efficiency of RCM analysis.

[0029] In some executable embodiments, in step S20, determining the main functions of the target system according to the function information file includes: S21: Acquire the upstream system and downstream system of the target system from the function information file.

[0030] S22: Determine the main function according to the output data of the upstream system and the input data of the downstream system.

[0031] As an example, based on the functional information file, analyze the functional description, input and output parameters, interfaces and dependencies between systems of the target system, and obtain the upstream and downstream systems of the target system based on the functional description, input and output parameters, interfaces and dependencies between systems of the target system.

[0032] As another example, the function of the target system is determined according to the functional module division in the single-line diagram in the functional information file. The target system is a switch cabinet, the upstream system is a transformer, and the downstream system can be understood as a power transmission user. Therefore, the main function of the switch cabinet is to controllably distribute the power supply of the transformer to the downstream load, that is, the power transmission user. The output data of the upstream system and the input data of the downstream system include voltage, current, power, frequency, power quality, etc.

[0033] In some executable embodiments, in step S30, the auxiliary function of the target system is generated according to the function information file, including: S31: Obtain implementation class functions according to the connection relationship of the devices or components provided in the function information file.

[0034] Specifically, the recorded information about the implementation class function in the function information file is extracted by using keyword extraction technology or based on semantic understanding, and the implementation class function is obtained by combining the recorded information with the connection relationship between the device or component. For example, in the function information file, the recorded information about the implementation class function refers to a detailed description related to the specific function implementation of the device, system or component. The recorded information usually involves how the device performs a task, the operation process to meet specific requirements, the required conditions and related parameters, etc.

[0035] S32: Classify the implementation class functions according to the preset requirement functions to obtain auxiliary functions.

[0036] Specifically, implementation functions refer to specific functions that target system equipment needs to meet when implementing demand functions. For example, there are safety requirements in the target system of the power distribution system, and there are further lower-level implementation function requirements: eliminating industrial safety risks during the operation of power transmission and distribution. On the basis of this demand function, the industrial safety requirements of the power distribution system can be solved by implementing class functions including grounding the housing of live equipment from the function information file. Therefore, the corresponding auxiliary functions include grounding the housing of live equipment.

[0037] In some scenarios, you can also review whether the implementation functions are complete based on user needs. For example, you can obtain user needs through requirement documents and then determine whether the implementation functions can meet user needs.

[0038] In some scenarios, semantic understanding technology can be used to extract relevant function records from the function information file according to the preset required functions, and obtain the implementation functions under each type of preset required functions. Further, the implementation functions are analyzed and summarized to obtain auxiliary functions.

[0039] Optionally, a level of classification can be added between the preset demand functions and the implementation functions. The implementation functions under each preset demand function can be divided into protection functions, alarm functions, control functions, display functions, isolation functions, efficiency functions, inclusion functions, appearance functions, redundancy functions, and comfort functions.

[0040] Among them, protection functions are used to ensure that the target system can continue to operate in the face of external threats or operational errors.

[0041] Among them, the alarm function is used to notify the user or administrator of the target system when an abnormality or emergency is detected.

[0042] Among them, control functions involve the management and regulation of target system operations, such as user input processing, automated control logic, and decision making, thereby ensuring that the target system responds to user instructions and internal state changes in a predetermined manner.

[0043] Among them, the display function is responsible for providing information to the user, including screen display, indicator light, sound prompt, etc. These functions ensure that the user can intuitively understand the target system status and operation results.

[0044] Among them, isolation functions are used to provide physical or logical isolation between different parts of the target system to prevent fault spread or protect sensitive areas. This is particularly important in power target systems, network communications, and data management.

[0045] Among them, efficiency functions focus on improving the performance and resource utilization of the target system, such as energy management, task scheduling, and load balancing. These functions are designed to optimize the operation of the target system, reduce waste, and improve response speed.

[0046] Among them, the containment function ensures that the target system can contain the substance within a certain space and avoid releasing it into the environment.

[0047] Among them, appearance functions involve the aesthetic design of the target system, including shape, color, material and overall style. These functions affect the user's first impression and usage experience, and are crucial to brand image and market acceptance.

[0048] Among them, redundancy functions refer to redundant elements in the target system design, such as backup power supplies, backup sensors, or multiple safety checks, to ensure that the target system can continue to operate when key components fail, maintaining the normal operation of the main functions.

[0049] Among them, comfort functions focus on improving user comfort and convenience, such as temperature control, noise suppression and ergonomic design.

[0050] In some scenarios, auxiliary functions provide support for the realization of the main functions and safety and production management from multiple aspects, and logically correspond to the main functions and the external requirements that the main functions need to meet according to the demand-type functions. Specifically, external requirements include regulatory requirements, industry requirements, enterprise requirements, and customer requirements.

[0051] In some executable embodiments, before step S32, before classifying the implementation class functions according to the preset requirement functions to obtain the auxiliary functions, the following steps are included: S50: Determine the device list of the target system from the function information file.

[0052] It should be noted that the accuracy of the equipment can be ensured by obtaining the equipment list from the function information file, and the integrity of the auxiliary functions can be ensured in the subsequent verification.

[0053] S60: Verify whether the implementation class function list of the implementation class function corresponds to at least one device in the device list, and whether all devices in the device list correspond to at least one implementation class function in the implementation class function list.

[0054] S70: If the verification is passed, the implementation class functions are classified according to the preset requirement functions to obtain the auxiliary functions.

[0055] Specifically, the positive and negative methods of auxiliary function analysis are set through the logical relationship between the main function and auxiliary function, between auxiliary function and auxiliary function, and between auxiliary function and equipment, and the results of the two methods complement each other. The positive method of auxiliary function analysis is to divide the auxiliary functions into demand-type functions and implementation-type functions. The demand-type functions are defined as the requirements of all relevant parties for the main functions, and the implementation-type functions are defined as the implementation methods of the demand-type functions. The reverse method of auxiliary function analysis is to correspond all equipment to the implementation-type functions.

[0056] In some scenarios, the implementation class functions are classified according to the preset required functions to obtain auxiliary functions, which also include: if the verification fails, it is fed back that there are anomalies in the implementation class function list and re-analysis is required.

[0057] Specifically, the device should correspond to at least one implementation function to ensure that the device is a necessary device, not a redundant device. When a device lacks a corresponding implementation function, it means that the corresponding auxiliary function lacks an assessment of the device function, the auxiliary function is incomplete, and there are safety issues. Therefore, the integrity of the auxiliary function is enhanced through re-analysis, and the quality of RCM analysis is improved.

[0058] It should be noted that due to the logical relationship between the main functions and the auxiliary functions, the integrity of the auxiliary functions can be verified and the stability of the main functions can be improved to ensure the safety of the target system production.

[0059] In some executable embodiments, the preset demand functions include: safety and environmental protection functions, production functions, economic and efficiency functions, operation and maintenance functions, and management functions.

[0060] Specifically, security and environmental protection functions: Security functions ensure the security of the target system, including physical security, information security, and usage safety. Environmental protection functions focus on the impact of the target system on the environment. Various types of emissions and power consumption must meet the requirements of the functional information document to ensure that the operation of the target system complies with environmental protection standards and regulations.

[0061] Production functions include production efficiency optimization, quality control, production monitoring and production planning management, etc. The goal of production functions is to improve productivity, reduce costs and ensure product quality.

[0062] Economic and efficiency functions include cost control, revenue growth, return on investment (ROI) analysis, and market competitiveness improvement. Economic and efficiency functions are designed to maximize profits, optimize resource allocation, and improve market competitiveness.

[0063] Operation and maintenance functions involve the daily operation and maintenance of the target system, including target system monitoring, troubleshooting, performance optimization, and regular maintenance. These functions ensure the stability and reliability of key functions and target systems, reduce outage time, and improve overall service quality.

[0064] Management functions support the organization's daily management tasks of target systems or major functions, such as human resource management, financial management, project management and decision support. These functions help management monitor business performance, formulate strategies and optimize business processes.

[0065] Each type of demand function is an important part of the target system, reflecting the needs and expectations of different stakeholders. When implementing these functions, it is necessary to take into account their interdependencies and potential conflicts and ensure that they are consistent with the overall goals and strategies of the organization.

[0066] Furthermore, the preset requirement class function also includes other classes.

[0067] If there are implementation functions that cannot be classified into the above types, they will be classified into other categories. It can be understood that the names of other categories are not limited and can be set according to actual needs.

[0068] In some executable embodiments, in step S40, fault management analysis is performed on the auxiliary functions and the main functions to obtain target system analysis guidelines, including the following steps: S41: Determine the devices or components corresponding to the main functions and auxiliary functions according to the function information file.

[0069] Furthermore, a list of corresponding equipment or components may be obtained based on the single-line diagram in the function information file and / or the equipment internal component diagram in the equipment manual.

[0070] S42: Generate failure modes corresponding to equipment or components, compile failure impacts, failure consequences, failure prevention measures, and failure consequence management measures, and obtain target system analysis guidelines.

[0071] Specifically, in some scenarios, failure prevention measures and failure consequence management measures can be classified into one category, such as maintenance strategy.

[0072] Specifically, the failure mode template includes the failure modes corresponding to all devices in the target system. According to the failure mode, the failure impact is analyzed, the failure consequence is determined, and the failure prevention measures and failure consequence management measures are determined according to the cause of the failure.

[0073] The consequence of the auxiliary function failure must be coordinated with its demand-type function. If it cannot be coordinated, the position of the implementation function in the demand-type function should be adjusted retroactively.

[0074] In some executable embodiments, in step S42, a failure mode corresponding to the device or component is generated, and the failure impact, failure consequence, failure prevention measures, and failure consequence management measures are written, including: S421: Extract the failure mode of the device or component from the failure mode library using a keyword extraction method.

[0075] Specifically, the failure mode library includes a list of failure modes. Each device or component corresponds to at least one failure mode. For example, the switch device corresponds to mis-opening, mis-closing, refusal to open, refusal to close, poor contact, and insulation breakdown.

[0076] S422: Generate fault impact according to the usage scenarios corresponding to the main functions, auxiliary functions and target systems.

[0077] Furthermore, the fault impacts caused by different usage scenarios are inconsistent. The specific results are based on the results recorded in the functional letter document. This includes the fault impacts provided by the customer and the fault impacts obtained based on the professional knowledge involved in the target system.

[0078] S423: Match the fault consequence according to the fault impact.

[0079] Specifically, the failure consequence is the final impact, that is, the worst result that will occur when this failure mode occurs.

[0080] S424: Obtain basic operation and maintenance strategies of the equipment or components from the function information file using keyword extraction technology.

[0081] S425: Obtain fault prevention measures and consequence management measures based on the basic operation and maintenance strategy, usage scenarios, and user levels involved in the target system.

[0082] Specifically, the user levels can be divided into important and ordinary. When facing important level customers, the maintenance time in the basic operation and maintenance strategy can be shortened by 10%.

[0083] In an executable embodiment, when the failure mode is generated, the devices or components involved are also listed.

[0084] In an executable embodiment, fault management analysis is performed on the main functions and auxiliary functions to obtain target system analysis guidelines, which also includes: Each main function and auxiliary function is divided into corresponding functional faults according to the functional information file.

[0085] Specifically, functional failure includes complete unavailability of functions and partial availability of functions.

[0086] Furthermore, functional failures may be classified according to threshold requirements for target systems or functions in the functional information file.

[0087] It can be understood that the connection relationship between equipment and components is analyzed, the equipment and components involved in the corresponding functional failure are obtained, and then the failure mode, failure impact, failure consequence, failure prevention measures and failure consequence management measures are generated, and finally the target system analysis guidelines are obtained.

[0088] In some executable embodiments, the functional information files include design specifications, maintenance records, equipment descriptions, and operation manuals.

[0089] Specifically, the design specification document describes in detail the design intent, structure, components, working principle and performance standards of the target system or product. These documents usually include the target system architecture diagram, component specifications, interface definitions, user interface design and user experience process. The design specification provides the development team with specific guidance on how to build the target system to ensure that the final product can meet the predetermined functional and performance requirements.

[0090] Maintenance records document the failures, maintenance activities, and maintenance history that occurred during the operation of the target system or equipment. These records include the description of the failure, the date of the repair, the parts replaced, the maintenance personnel, and the repair results. Maintenance records are very useful for analyzing the reliability of equipment, predicting potential problems, and optimizing maintenance plans. They also help comply with safety standards and regulatory requirements to ensure that equipment is properly maintained.

[0091] Equipment documentation provides operating instructions, technical specifications, performance parameters, and usage limitations for equipment. These documents typically include operating manuals, safety guidelines, maintenance procedures, and troubleshooting steps. Equipment instructions ensure that users can use the equipment correctly and safely and find solutions quickly when problems arise. They are essential for training operators, improving equipment efficiency, and reducing operating errors.

[0092] In some executable embodiments, in step S10, obtaining a function information file of a target system analyzed by RCM includes: S11: Determine the target system for RCM analysis from the system to be analyzed based on the technical documents of the system to be analyzed and the estimated analysis time limit.

[0093] Specifically, when conducting RCM analysis, you first need to determine the analysis object and divide the target system boundaries according to relevant standards, then build the target system structure diagram and determine its functions and performance indicators. Next, perform failure mode analysis on each device or component, assess risks, and formulate corresponding maintenance strategies. At the same time, within the estimated analysis time limit, it is also necessary to evaluate the reliability of the target system, including technical indicators such as the completion of performance indicators, to ensure the stability and performance of the target system. Through this series of steps, the system to be analyzed can be systematically divided, the target system for RCM analysis can be determined, and the comprehensiveness and effectiveness of the analysis can be ensured.

[0094] S12: According to the target system, obtain the design description, maintenance record, equipment description and operation manual from the data of the system to be analyzed, and determine the design description, maintenance record, equipment description and operation manual as functional information files.

[0095] Specifically, technical documents may include wiring diagrams, flow charts and logic diagrams.

[0096] In order to obtain functional information files from the data of the target system to be analyzed according to RCM analysis of the target system, it is necessary to determine the required file types, including design instructions, operation manuals, maintenance records, etc., and then collect these documents from the target system archives or relevant departments. Next, review the design documents to understand the target system design, analyze the operation and maintenance manuals to grasp the daily use and maintenance requirements, check the fault and maintenance records to identify problems and their frequency, evaluate the equipment specifications to understand the performance parameters, and organize user feedback to obtain actual experience and needs. Finally, compile a list of documents, verify the integrity of the documents, and archive them to ensure a comprehensive and accurate data basis for RCM analysis.

[0097] In one executable embodiment, Figure 2 As shown, the RCM analysis method based on auxiliary function optimization includes the following steps: Step 1: Define the analysis boundary (determine the target system for RCM analysis).

[0098] Step 2: Collect and analyze data (obtain functional information files of the target system).

[0099] Step 3: List the main functions (determine the main functions of the target system based on the functional information file).

[0100] Step 4: List the auxiliary functions (generate the auxiliary functions of the target system based on the main functions and function information files).

[0101] Furthermore, the auxiliary functions of the target system are obtained by combining the equipment list with the functions to realize various requirements (implementation functions). The various requirements mainly include the requirements to ensure the main functions, external safety requirements, external environmental protection requirements, external economic requirements, external cost requirements, external operation and maintenance requirements, external management requirements and other requirements.

[0102] Step 5: Use the failure mode template to list the failure mode, failure impact, failure consequences and management measures to obtain the target system analysis guidelines.

[0103] It should be noted that the specific implementation of the above steps 1 to 5 refers to the above steps S10 to S40, which will not be repeated here.

[0104] In one embodiment, a computer device is provided. The computer device may be a server, and its internal structure diagram may be as follows: Figure 3 As shown. The computer device includes a processor, a memory, a network interface and a database connected through a system bus. Among them, the processor of the computer device is used to provide computing and control capabilities. The memory of the computer device includes a non-volatile storage medium and an internal memory. The non-volatile storage medium stores an operating system, a computer program and a database. The internal memory provides an environment for the operation of the operating system and the computer program in the non-volatile storage medium. The database of the computer device is used for an RCM analysis method based on auxiliary function optimization. The network interface of the computer device is used to communicate with an external terminal through a network connection. When the computer program is executed by the processor, an RCM analysis method based on auxiliary function optimization is implemented.
