[0044] To make the objectives, technical solutions and advantages of the present invention clearer, the following will clearly and completely describe the technical solutions in the present invention in conjunction with the drawings in the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art without creative efforts based on the embodiments in the present invention fall within the scope of protection of the present invention.

[0045] Systems engineering is a scientific method for analyzing and studying the components, organizational structure, information flow, control mechanisms, etc. of a system in order to best achieve the purpose of the system. It uses various organizational management techniques to coordinate and match the relationship between the whole and the parts of the system, and achieve the optimal overall operation. Systems engineering is different from general traditional engineering. The objects it studies are not limited to specific engineering material objects, but any kind of system.

[0046] Industrial products are often composed of multiple parts to jointly achieve multiple required functions and performances. The long-term stable reliability of their key functions and performances is the premise for the product to have complete functions and good performances. Metrology is a technical means to ensure that the accuracy indicators of the key functions and performances of industrial products are in good condition.

[0047] In the related methods, industrial metrology is to verify and calibrate the test instruments and equipment used in the product R & D and production process. There is no systematic consideration of the metrology requirements of the product in the product design process, resulting in many problems in later metrology, such as the inability to detect the performance of some products, the lack of necessary hardware interfaces, signal adapters or necessary test software; the quality of the detection and calibration methods of some equipment is not high, the metrology traceability chain is not clear, and the effectiveness of detection and calibration cannot be determined; the existing resources are not effectively combined and fully utilized, the configuration is improper or unreasonable, and the metrology cost is high. To avoid these problems, it is necessary to carry out metrology design activities in the product design process according to the detection and calibration requirements of the product in the stages of development, production, use, maintenance, etc., so that the product has metrology, ensure that all parameters that need to be measured to ensure the normal and accurate operation of the product are easy to obtain and measure, and minimize the number and duration of required detection and calibration. The significance of metrology design mainly lies in that if the product has metrology, the changes in the key function and characteristic values can be found through regular detection and calibration with measurement traceability, and then the out-of-tolerance, abnormality and failure of the product can be judged and disposed according to the value changes and their measurement uncertainties.

[0048] The idea of systems engineering has been widely applied in many fields of industrial product design. Metrology design should be combined with the idea of systems engineering and organically integrated into the product design process to improve the reliability of industrial products while reducing the manufacturing and use costs, and there is no effective method for metrology design of industrial products in the related methods.

[0049] Aiming at the defects in the related methods, the present invention proposes a metrology design method for industrial products, Figure 1 which is a schematic flow chart of the metrology design method for industrial products provided by the present invention. Referring to Figure 1 , the metrology design method for industrial products provided by the present invention may include:

[0050] Step 110: Generate the compliance requirement text for the industrial product based on the compliance requirement information of the industrial product, and perform text analysis on the compliance requirement text to determine multiple quantitative requirements of the industrial product;

[0051] Step 120: Analyze the multiple quantitative requirements using a Model - Based Systems Engineering (MBSE) tool to determine the importance, occurrence probability, and assurance cost of each quantitative requirement;

[0052] Step 130: Screen the multiple quantitative requirements based on the importance, occurrence probability, and measurement cost to obtain the measurement requirement information of the industrial product;

[0053] Step 140: Perform measurable design on the industrial product based on the measurement requirement information.

[0054] The execution subject of the industrial product measurable design method provided by the present invention can be an electronic device, a component in the electronic device, an integrated circuit, or a chip. The electronic device can be a mobile electronic device or a non - mobile electronic device. Exemplarily, the mobile electronic device can be a mobile phone, a tablet computer, a laptop computer, a handheld computer, an ultra - mobile personal computer (UMPC), a netbook, or a personal digital assistant (PDA), etc., and the non - mobile electronic device can be a server, a Network Attached Storage (NAS), or a personal computer (PC), etc. The present invention does not make specific limitations.

[0055] Taking a computer executing the industrial product measurable design method provided by the present invention as an example, the technical solution of the present invention will be described in detail below.

[0056] In step 110, based on the compliance requirement information of the industrial product, generate the compliance requirement text for the industrial product, and perform text analysis on the compliance requirement text to determine multiple quantitative requirements of the industrial product.

[0057] Determine the compliance requirements as the input for subsequent measurable analysis. The compliance requirements can include safety standards, product standards, metrology technical specifications, and stakeholder requirement information, etc.

[0058] Optionally, the specific requirement analysis process can be as Figure 2 shown in the requirement analysis process schematic diagram provided by the present invention. The process of capturing compliance requirements specifically includes:

[0059] Combined with the requirements for measurement accuracy, consistency, and traceability of the product itself and testing equipment in stages such as the research and development, production, use, and maintenance of industrial products, refine the functional scenarios that require metrology;

[0060] Based on the functional scenarios, identify the groups or organizations that are directly or indirectly related to the metrology activities in the scenarios, and form a stakeholder information table;

[0061] With the help of MBSE tools, decompose the requirements proposed by stakeholders, including functional requirements and performance requirements, to form a stakeholder requirements decomposition table;

[0062] Statistically record the compliance requirements in the above-mentioned multiple tables obtained, and generate a compliance requirement text. Conduct text analysis on the compliance requirement text, and according to whether it has quantitative value characteristics, classify and determine the quantitative metrology requirements for capturing measurable requirements, and obtain a measurable requirement parameter capture table.

[0063] After obtaining the measurable requirement parameter capture table, classify the measurable requirement parameters in the measurable requirement parameter capture table.

[0064] Based on the analysis of the degree of out-of-tolerance hazard and the frequency of out-of-tolerance occurrence, calculate the measurable requirement level number, classify based on the measurable requirement level number, determine critical, important, and general requirements, and conduct a comprehensive analysis of the measurable requirements to obtain a comprehensive analysis table of measurable requirements.

[0065] Optionally, conduct text analysis on the compliance requirement text, which can specifically include:

[0066] Obtain the compliance requirement text, use data mining and machine learning techniques to analyze a large amount of compliance requirement text data, and mine the hidden patterns and rules therein to determine multiple quantitative requirements of industrial products.

[0067] Alternatively, use a text classification algorithm to classify the compliance requirement text according to the requirement type or theme to better organize and analyze relevant information, and thus extract quantitative requirements.

[0068] In step 120, based on the model-based systems engineering MBSE tool, analyze the multiple quantitative requirements to determine the importance of each quantitative requirement, the occurrence probability of each quantitative requirement, and the metrology cost of each quantitative requirement.

[0069] MBSE tools refer to Model-Based Systems Engineering tools, which are used to support systems engineers in adopting a model-driven approach during the system development process. These tools can help systems engineers create, manage, and analyze system models to better understand and describe the requirements, structure, behavior, and interaction relationships of the system.

[0070] MBSE tools provide various analysis tools and verification functions to help systems engineers check the consistency, integrity, and correctness of the models, identify potential problems, and make improvements. Moreover, MBSE tools support the simulation and emulation of system models to evaluate system performance, behavior, and interaction, and conduct virtual verification and validation.

[0071] Based on the MBSE tools, analyze the multiple quantitative requirements determined in step 110 to determine the importance of each quantitative requirement, the occurrence probability of each quantitative requirement, and the measurement cost of each quantitative requirement.

[0072] The specific analysis process can be as follows:

[0073] Based on the MBSE tools, analyze the multiple quantitative requirements to determine the severity of the impact of the demand deviation of each quantitative requirement on product production and use, the occurrence frequency of the demand deviation of each quantitative requirement, and the measurement and detection methods of each quantitative requirement. Among them, the demand deviation of a quantitative requirement usually refers to the situation where, during product production or use, a specific quantitative requirement fails to reach the expected level in actual testing or execution. This situation may lead to consequences such as product quality problems, user dissatisfaction, or project delays.

[0074] Based on the severity of the impact of the demand deviation of each quantitative requirement on product production and use, determine the importance of each quantitative requirement; based on the occurrence frequency of the demand deviation of each quantitative requirement, determine the occurrence probability of each quantitative requirement; based on the measurement and detection methods of each quantitative requirement, determine the measurement cost of each quantitative requirement.

[0075] In step 130, based on the importance, the occurrence probability, and the measurement cost, screen the multiple quantitative requirements to obtain the measurement requirement information of the industrial product.

[0076] It is possible to evaluate the demand level number based on the importance of the quantitative requirement, the occurrence probability of the quantitative requirement, and the measurement cost of the quantitative requirement, so as to realize the screening process of the quantitative requirement based on the evaluated level.

[0077] Specifically, it is necessary to evaluate the importance of each quantitative requirement for product production and use. Some requirements may be crucial for product performance, safety, or functionality implementation, while others may be less important. The importance level can be determined by discussing with stakeholders and weighing the contribution of each requirement to the project goals.

[0078] Based on the results of the requirement level assessment, the team can develop corresponding screening criteria and processes to prioritize high-level requirements, ensuring the rational allocation of resources and the achievement of product goals.

[0079] During the product production and use process, continuously monitor and update the requirement level assessment, and make adjustments and optimizations according to the actual situation.

[0080] By comprehensively evaluating and screening quantitative requirements, the project can be planned and managed more effectively, ensuring that key requirements are fully met, minimizing project risks, and increasing the likelihood of project success.

[0081] In step 140, based on the metrological requirement information, the industrial product is designed for metrology.

[0082] Clarify the metrological requirement information of the industrial product, that is, clarify the various quantitative requirements that the product should meet, such as dimensions, weight, speed, power, etc.

[0083] Convert the clarified quantitative requirements into specific parameters of the product design, ensuring that each quantitative requirement has corresponding design indicators. The design parameters should be measurable, that is, they can be verified whether they meet the requirements through actual measurement or testing means.

[0084] In the product design stage, consider how to measure and verify to ensure that the design parameters can be accurately measured and verified. Appropriate sensors, instruments, or specific test devices can be selected to achieve the measurement and verification of the design parameters.

[0085] For key design parameters, risk assessment is required to determine their allowable range, and corresponding tolerance design should be considered during the design process. Ensure that even if there are certain fluctuations or errors in the actual production process, the product can still meet the quantitative requirements.

[0086] Optionally, the metrological design can mainly include the following steps:

[0087] Detection scheme design. The detection scheme is a scheme for detecting the metrological requirements of industrial products, specifically including:

[0088] Measurement and testing methods selected or compiled item by item according to the product measurement requirements and demand levels; testing equipment selected or designed according to the measurement requirements and measurement and testing methods; testing interfaces and testing cycles designed according to the measurement requirements, measurement and testing methods, and testing equipment.

[0089] Calibration plan design. The calibration plan is a plan for calibrating the testing equipment of industrial products, specifically including:

[0090] Calibration requirements and calibration methods confirmed based on the testing equipment proposed in the testing plan; calibration equipment selected or designed according to the calibration requirements and calibration methods; calibration interfaces and calibration cycles designed according to the calibration requirements, calibration methods, and calibration equipment.

[0091] Construct a traceability chain. Based on the industrial products, testing equipment, and calibration equipment in the foregoing steps, reasonably construct a traceability chain that can be traced back to the measurement standard.

[0092] Design integration. Integrate the contents of the testing plan and calibration plan, analyze redundant situations such as different parameters and the possible use of the same equipment and the same interface in testing or calibration, and streamline the testing interfaces, testing equipment, calibration interfaces, calibration equipment, etc.

[0093] Compliance analysis. Analyze the compliance of the testing / calibration requirements, testing / calibration methods, testing / calibration equipment, testing / calibration interfaces, testing / calibration cycles, and the construction of the traceability chain based on the measurement requirements.

[0094] Optional, as Figure 3 As shown in the schematic diagram of the metrology design analysis process provided by the present invention, the design analysis includes the following steps:

[0095] Testing plan design. The testing plan is a plan for testing the parameters that need to be measured for the industrial product itself, specifically including:

[0096] Clarify the testing requirements. Screen and confirm the metrology requirement information, and determine the testing parameters and related information that need to be designed;

[0097] Determine the measurement and testing method. Determine a suitable measurement and testing method according to the confirmed testing requirements. Generally, if there are corresponding regulations and specifications, refer to the measurement and testing methods in the regulations and specifications; if there are no corresponding regulations and specifications or they are not applicable, compile the measurement and testing method by oneself;

[0098] Recommend testing equipment. Select the testing equipment that can meet the equipment testing requirements as the recommended testing equipment according to the testing requirements and measurement and testing methods;

[0099] Design the testing interface. Complete the design of the testing interface according to the measurement requirements, measurement and testing methods, and the recommended testing equipment;

[0100] Recommended detection period.

[0101] Calibration scheme design. The calibration scheme is a scheme for calibrating the detection equipment of industrial products, specifically including:

[0102] Clarify calibration requirements. According to the detection equipment proposed in the detection scheme, confirm its corresponding calibration requirements, including but not limited to calibration parameter names, value ranges, measurement uncertainties, calibration conditions, calibration positions, calibration methods, etc.

[0103] Determine the calibration method. Determine a suitable calibration method according to the confirmed calibration requirements. Generally, for those with corresponding regulations and specifications, refer to the calibration methods in the regulations and specifications; for those without corresponding regulations and specifications or those not applicable, self-develop calibration methods.

[0104] Recommend calibration equipment. Based on the calibration requirements and calibration methods, select calibration equipment that can meet the calibration requirements of the detection equipment as the recommended calibration equipment.

[0105] Design the calibration interface. For general detection equipment, there is no need to design a separate calibration interface. For special detection equipment, refer to the content of the detection interface design for calibration interface design.

[0106] Recommend the calibration period. Determine the calibration period according to the relevant metrological technical specifications of the equipment to be detected. In particular, it can also be determined based on actual detection data.

[0107] Construct a traceability chain. Based on the industrial products, detection equipment, and calibration equipment in the previous steps, reasonably construct a traceability chain that can be traced back to the metrological standard.

[0108] Design integration. Integrate the content of the detection scheme and the calibration scheme, analyze the redundancy situations such as different parameters and the possible use of the same equipment and the same interface in detection or calibration, and streamline the detection interface, detection equipment, calibration interface, calibration equipment, etc.

[0109] Compliance analysis. Based on the metrological requirements, analyze the compliance of the detection / calibration requirements, detection / calibration methods, detection / calibration equipment, detection / calibration interfaces, detection / calibration periods, and the construction of the traceability chain.

[0110] The industrial product metrology design method provided by the embodiments of the present invention constructs the design process of industrial product metrology from the perspective of systems engineering. This method follows the principle of forward design. Starting from requirements analysis, it completely gives the industrial product metrology requirements analysis method, obtains complete and effective metrology requirements, and gives a set of full-process design methods for the obtained requirements, filling the gap in the industrial product metrology design method and improving the accuracy and coverage of subsequent metrological detection of industrial products.

[0111] In one embodiment, text analysis is performed on the compliance requirement text to determine multiple quantitative requirements of the industrial product, including: identifying keywords in the compliance requirement text based on keyword extraction; and performing requirement analysis on the industrial product based on the keywords to determine multiple quantitative requirements of the industrial product.

[0112] For keyword extraction from the compliance requirement text, natural language processing techniques or specialized keyword extraction tools can be used. Keywords related to metrology requirements are identified, such as "dimension", "weight", "speed", "power", etc.

[0113] The extracted keywords are classified and filtered to better understand the corresponding metrology requirement fields. The keywords can be classified into different categories such as dimension category, weight category, speed category, power category, etc. for subsequent requirement analysis.

[0114] For each keyword category, metrology requirement analysis is performed to determine the quantitative requirements of the industrial product in the corresponding field. For example, in dimension requirements, the maximum dimension, precision requirements, tolerance range, etc. of the product can be analyzed. In weight requirements, the maximum weight, load capacity requirements, etc. of the product can be analyzed.

[0115] In one embodiment, a Model - Based Systems Engineering (MBSE) tool is used to analyze the multiple quantitative requirements to determine the importance, occurrence probability, and metrology cost of each quantitative requirement, including: analyzing the multiple quantitative requirements using the MBSE tool to determine the severity of the requirement deviation, the occurrence frequency of the requirement deviation, and the metrology detection method for each quantitative requirement; determining the importance of each quantitative requirement based on the severity of the requirement deviation; determining the occurrence probability of each quantitative requirement based on the occurrence frequency of the requirement deviation; and determining the metrology cost of each quantitative requirement based on the metrology detection method of each quantitative requirement.

[0116] Specifically, an MBSE tool is used to establish a system model, and each quantitative requirement is incorporated into the model in the form of parameters. The model data is analyzed to determine the deviation situation of each quantitative requirement, that is, the gap between the actual value and the required value.

[0117] Based on the numerical size and impact degree of the requirement deviation, the severity of the deviation of each quantitative requirement is evaluated. Quantitative indicators or evaluation models can be used to quantify the severity of the deviation, such as percentage error, degree of performance degradation, etc.

[0118] Analyze historical data or simulated data to determine the occurrence frequency of out-of-tolerance for each quantitative requirement, that is, the probability of out-of-tolerance occurring in actual applications of the requirement. Consider factors such as product characteristics, environmental factors, and operating conditions to evaluate the likelihood of out-of-tolerance occurrence.

[0119] Based on the characteristics and out-of-tolerance likelihood of each quantitative requirement, determine appropriate metrological detection methods to monitor the fulfillment of the requirement. Technologies such as sensor monitoring, real-time data acquisition, and simulation can be used for requirement detection.

[0120] Combined with the severity and scope of impact of requirement out-of-tolerance on product production and use, evaluate the importance of each quantitative requirement and determine its contribution to system performance and functions. Requirements with high importance require more stringent control and monitoring to ensure the overall system performance.

[0121] Combined with the occurrence frequency of requirement out-of-tolerance and the effectiveness of metrological detection methods, determine the occurrence probability of each quantitative requirement, that is, the likelihood of out-of-tolerance occurring within a certain period of time.

[0122] Based on factors such as the complexity of metrological detection methods, required equipment, and resource investment, evaluate the metrological cost of each quantitative requirement. Metrological costs include direct costs such as personnel, equipment, and R & D required for detection, disassembly, and adjustment, as well as indirect costs brought about by the impact of metrological activities on product use.

[0123] In one embodiment, based on the importance, the occurrence probability, and the metrological cost, screen the multiple quantitative requirements, including: based on the requirement level index formula, determine the requirement level index of each quantitative requirement, and based on the requirement level index, screen the multiple quantitative requirements; the requirement level index formula is: ; where is the requirement level index of the quantitative requirement, is the importance of the quantitative requirement, is the occurrence probability of the quantitative requirement, is the metrological cost of the quantitative requirement.

[0124] Specifically, calculate the requirement level index and complete the classification of requirements. Screen the multiple quantitative requirements based on importance, occurrence probability, and metrological cost.

[0125] For the classification of importance, occurrence probability, and measurement cost, the importance can be divided into four levels: mild (1, 2, 3), medium (4, 5, 6), critical (7, 8), and catastrophic (9, 10); the occurrence probability of out-of-tolerance is classified. Generally, the occurrence probability can be divided into five levels: extremely low (1), relatively low (2, 3), medium (4, 5, 6), high (7, 8), and very high (9, 10); the measurement cost is classified. Generally, the measurement cost can be divided into five levels: extremely low (1), relatively low (2, 3), medium (4, 5, 6), high (7, 8), and very high (9, 10).

[0126] It can be understood that the requirement level index of quantitative requirements is determined based on the product of the importance of quantitative requirements, the occurrence probability of quantitative requirements, and the measurement cost of quantitative requirements. If the value of the product is larger, it indicates that the requirement level is higher; if the value of the product is smaller, it indicates that the requirement level is lower.

[0127] In one embodiment, based on the measurement requirement information, the metrology design of the industrial product is carried out, including: based on the measurement requirement information, determining the measurement interfaces of each measurement requirement, the signal adapters of each measurement requirement, and the test software of each measurement requirement; setting the measurement interfaces of each measurement requirement, the signal adapters of each measurement requirement, and the test software of each measurement requirement to carry out the metrology design of the industrial product.

[0128] According to the characteristics and data transmission requirements of each measurement requirement, determine the corresponding measurement interface types, including digital interfaces, analog interfaces, communication interfaces, etc. Determine the physical connection method and protocol standard of the measurement interface to ensure compatibility with the measurement device or system.

[0129] For different measurement requirements and measurement interfaces, select appropriate signal adapters to implement functions such as signal conversion, amplification, and filtering to ensure the accuracy and stability of the signal. Select the adapter according to signal types (analog signal, digital signal), characteristics such as voltage and current, and adjust the adapter parameters according to requirements.

[0130] For each measurement requirement, design the corresponding test software or configure the test plan to verify the correct connection of the measurement interface, the normal operation of the signal adapter, and the accuracy of data acquisition. Determine the functional modules, test processes, and data processing methods of the test software to ensure the reliability and consistency of the test results.

[0131] For the settings of the measurement interface, signal adapter, and test software, combined with the product design and manufacturing process, implement the metrology design scheme. Ensure the stability, reliability, and accuracy of the metrology system to meet the product quality control and monitoring requirements.

[0132] In one embodiment, after the metrological design of the industrial product is performed based on the metrological requirement information, the following steps are further included: determining the calibration requirements and the calibration method of the industrial product based on the metrological requirement information; and determining the detection periods of the metrological interface, the signal adapter, and the test software based on the calibration requirements and the calibration method.

[0133] Based on the metrological items in the metrological requirement information and in combination with the usage environment and application requirements of the product, determine the calibration requirements for each metrological item. The calibration requirements include accuracy requirements, stability requirements, repeatability requirements, etc., to ensure that the product can meet the accurate metrology requirements during use.

[0134] According to the calibration requirements and product characteristics, select appropriate calibration methods and standards to ensure the metrological accuracy and traceability of the product. The calibration methods can include laboratory calibration, on-site calibration, remote calibration, etc. The specific selection of the calibration method needs to consider the limitations of cost, time, and resources.

[0135] Based on the calibration requirements and the calibration method, determine the detection periods of the metrological interface, the signal adapter, and the test software. The detection periods can be determined according to factors such as the usage frequency of the product, environmental conditions, and calibration stability, and generally can be selected according to standard specifications or experience.
