Description

Technical Field

[0001] The invention relates to the field of control panel performance testing and analysis, and in particular to an intelligent analysis system for performance testing of a household appliance control panel. Background Art

[0002] As the core control unit of modern smart appliances, home appliance control boards are embedded electronic devices that integrate a microprocessor, sensor interface, power driver module, and communication unit. They use pre-programmed logic to monitor and precisely control the appliance's operating status in real time. Typical applications include air conditioning temperature control systems, washing machine timing controllers, and microwave oven power regulation modules. The performance of a control board directly determines the functional reliability, energy efficiency, and safety of home appliances. Key indicators such as hardware circuit stability, software algorithm robustness, and anti-interference capabilities have a decisive impact on the end-user experience.

[0003] However, existing household appliance control panel performance testing methods still have some limitations and shortcomings in practical applications.

[0004] For example, Chinese patent CN114764109A discloses a method, device, equipment, and system for testing electrical appliance performance. This method uses a test terminal to perform the following steps: sending a test command to the appliance under test to trigger it to execute a preset functional program; acquiring real-time performance parameter data while the appliance is operating; and comparing and analyzing these parameters against preset thresholds to generate a test report. This solution replaces manual testing with an automated process, effectively reducing labor costs and operational errors, significantly improving test efficiency and result accuracy, and meeting the quality control requirements of large-scale production. The system correspondingly includes a command issuing module, a data acquisition module, and an analysis and processing module to implement these functions.

[0005] For example, the Chinese patent with authorization announcement number CN117075018B discloses a BMS control panel performance test intelligent analysis and management system, which is characterized by including: a sample division module, an electrical performance test module, an electrical performance analysis module, a working performance test module, a working performance analysis module, a performance analysis module and a test result feedback terminal; through overcurrent, overvoltage and working performance tests, a performance compliance coefficient is generated and a multi-dimensional analysis is performed; combined with an in-depth analysis of the display times, values ​​and response time accuracy in the discharge test, the feedback is fed back to the test terminal to achieve the improvement of the timeliness and effect of production plan optimization, while ensuring display accuracy and response timeliness.

[0006] The above patent adopts a single performance testing strategy for the performance test of the control panel, that is, detecting various performance indicators of the control panel and comparing them with the set values ​​or standard values, and then conducting performance evaluation and judging whether the control panel is qualified. It does not take into account the differences in the performance of the control panel under different working environments and does not test the performance of the control panel under different working environments based on the principle of a single variable, nor does it analyze the sensitivity of the control panel to the working environment. Therefore, it cannot provide reference opinions for manufacturers to optimize the design of performance shortcomings. Summary of the Invention

[0007] In view of the above problems, the present invention proposes an intelligent analysis system for performance testing of household appliance control panels, which realizes the function of testing and analyzing the performance of control panels.

[0008] The technical solution adopted by the present invention to solve its technical problem is: the present invention provides an intelligent analysis system for performance testing of household appliance control panels, including: a working environment simulation module: according to environmental variables such as temperature, relative humidity, voltage fluctuation ratio, mechanical vibration frequency, salt spray concentration, and dust concentration, various working environments of the control panel are set based on the single variable principle.

[0009] Control group setting module: Set the control working environment for each group and place the control board in it to power on and run the benchmark test, and collect the control performance parameters of each group of control boards.

[0010] Environmental adaptability test module: Tests the performance parameters of the control board under various working environments, and compares them with the reference performance parameters and performance parameter standards to obtain the scores of the electrical performance indicators, functional indicators, and reliability indicators of the control board under various working environments.

[0011] Performance qualification evaluation module: Based on the scoring results of the control board, the qualification of the control board is determined, and the failure rate of the electrical performance, function, and reliability of the control board under various working environments is calculated.

[0012] Environmental sensitivity analysis module: Evaluates the control panel's sensitivity ranking to the working environment and the ranking of the degree of impact of the working environment on indicators, and obtains the environmental sensitivity analysis results of the control panel.

[0013] Database: Stores the security range of environment variables and control panel performance parameter standards.

[0014] Compared with the prior art, the intelligent analysis system for performance testing of household appliance control panels described in the present invention has the following beneficial effects: 1. Comprehensive coverage of multi-environmental variable testing to improve test accuracy: The present invention simulates multiple environmental variables such as temperature, humidity, voltage fluctuations, mechanical vibrations, salt spray concentration, dust concentration, etc., and tests the adaptability of the control panel one by one based on the single variable principle. It can comprehensively cover the complex environmental conditions that may be encountered in actual use, avoid test errors caused by multi-variable interference, and significantly improve the accuracy and reliability of the test results.

[0015] 2. Benchmarking and standardized assessment to ensure comparability of results: This invention provides a unified benchmark for performance testing in different environments by setting a reference working environment and running benchmark tests. In combination with international / industry standard parameters, it achieves standardized comparison of test results, ensuring the objectivity and comparability of the evaluation process and providing a scientific basis for quality control.

[0025] Furthermore, the specific working process of the working environment simulation module is: taking temperature, relative humidity, voltage fluctuation ratio, mechanical vibration frequency, salt spray concentration, and dust concentration as environmental variables of the control panel working environment.

[0026] It should be noted that temperature, humidity, voltage fluctuations, mechanical vibrations, salt spray, and dust are common environmental factors during the use of household appliances.

[0027] Extracts the security scope of environment variables stored in the database.

[0028] Each environmental variable is treated as the only variable that changes, and other environmental variables except the only variable that changes are maintained constant within the corresponding safety range. The test gear of the only variable that changes is set according to the preset rules, and then the only variable that changes is adjusted to place the control board in different gears for testing. The working environment of the control board with each environmental variable as the only variable that changes is obtained, which is recorded as various working environments and assigned corresponding labels.

[0029] In a specific embodiment, the values ​​of the environment variables other than the only variable being changed are set to the median of their safety ranges.

[0030] It should be noted that the labels corresponding to various working environments include temperature label, relative humidity label, voltage fluctuation ratio label, mechanical vibration frequency label, salt spray concentration label, and dust concentration label.

[0031] As a preferred solution, various working environments of the control panel are set based on the single variable principle. The specific process is: temperature is used as a changing environmental variable, and all environmental variables except temperature are maintained constant within the corresponding safety range. High temperature, low temperature and temperature cycle are set according to preset rules, where the temperature cycle includes the upper temperature limit, the lower temperature limit, and the interval length and number of switching between the upper and lower temperature limits.

[0034] The mechanical vibration frequency is used as a changing environmental variable, and all environmental variables except the mechanical vibration frequency are maintained constant within the corresponding safety range. The test mechanical vibration frequency is set according to the preset rules, and then the mechanical vibration frequency is regulated so that the control board is placed at each test mechanical vibration frequency for the set time in turn. The fourth working environment of the control board is obtained and a mechanical vibration frequency label is assigned.

[0035] The salt spray concentration is taken as the changing environmental variable, and all environmental variables except the salt spray concentration are kept constant within the corresponding safety range. The test salt spray concentration is set according to the preset rules, and then the salt spray concentration is regulated so that the control panel is placed in each test salt spray concentration for the set time in turn. The fifth working environment of the control panel is obtained and assigned a salt spray concentration label.

[0036] Dust concentration is used as a changing environmental variable, and all environmental variables except dust concentration are maintained constant within the corresponding safety range. Each test dust concentration is set according to the preset rules, and then the dust concentration is regulated so that the control panel is placed in each test dust concentration for the set time in turn. The sixth working environment of the control panel is obtained and a dust concentration label is assigned.

[0037] In a specific embodiment, in the first working environment of the control panel, the high temperature is set to +45°C and the low temperature is set to -10°C. In the temperature cycle, the upper temperature limit is +40°C, the lower temperature limit is -10°C, the interval between the upper and lower temperature limits is 3.5h, and the number of switches is 10 times.

[0038] As a preferred solution, the first working environment of the control board is that the control board successively experiences high temperature, low temperature and temperature cycle. The temperature cycle is that the temperature cycles within a temperature range consisting of a lower temperature limit and an upper temperature limit.

[0039] As a preferred solution, the control panel is placed in each test relative humidity in order from low to high, and the time maintained at each test relative humidity is the same, which is the set time.

[0040] In a specific embodiment, the second working environment of the control panel is set to test relative humidity of 50%, 60%, 70%, and 80%, respectively, and the duration of maintaining each test relative humidity is 2 hours.

[0041] As a preferred solution, the control board is placed in each test voltage fluctuation ratio in order from small to large, and the time maintained at each test voltage fluctuation ratio is the same, which is the set time length.

[0042] In a specific embodiment, in the third working environment of the control board, the test voltage fluctuation ratios are set to -15%, -10%, +10%, and +15% of the nominal voltage, respectively, and the duration of maintaining each test voltage fluctuation ratio is 30 minutes.

[0043] As a preferred solution, the control board is placed at each test mechanical vibration frequency in sequence from low to high, and the time maintained at each test mechanical vibration frequency is the same, which is the set time length.

[0044] In a specific embodiment, in the fourth working environment of the control panel, the test mechanical vibration frequencies are set to 60 Hz, 80 Hz, 100 Hz, 150 Hz, and 200 Hz, respectively, and the duration of maintaining each test mechanical vibration frequency is 10 minutes.

[0045] As a preferred solution, the control panel is placed in each test salt spray concentration in order from low to high salt spray concentration, and the time maintained at each test salt spray concentration is the same, which is the set time length.

[0046] In a specific embodiment, the fifth working environment of the control panel sets the test salt spray concentrations to 0.15 mg / m³, 0.20 mg / m³, 0.25 mg / m³, and 0.30 mg / m³, respectively, and the duration of maintenance at each test salt spray concentration is 24 hours.

[0047] As a preferred solution, the control panel is placed in each test dust concentration in order from low to high dust concentration, and the time maintained at each test dust concentration is the same, which is the set time length.

[0049] It should be noted that the present invention simulates multiple environmental variables such as temperature, humidity, voltage fluctuation, mechanical vibration, salt spray concentration, dust concentration, and tests the adaptability of the control board one by one based on the single variable principle. It can comprehensively cover the complex environmental conditions that may be encountered in actual use, avoid test errors caused by multivariate interference, and significantly improve the accuracy and reliability of the test results.

[0050] The control group setting module sets the control working environment of each group and respectively places the control panels therein to power on and run the benchmark test, and collects the control performance parameters of each group of control panels.

[0051] Furthermore, the specific working process of the control group setting module is: according to the safety range of each environmental variable, each value is selected from the safety range of each environmental variable in an equal gradient from low to high according to the set rules to obtain each group of control working environments of the control panel.

[0052] It should be noted that relevant tests should be performed on the control panel after it is installed.

[0053] In one specific embodiment, the control panel's stable operating temperature range is 0°C to 30°C, the relative humidity range is 20% to 40%, the voltage fluctuation ratio range is ±10% of the nominal voltage, the mechanical vibration frequency range is 5Hz to 50Hz, the salt spray concentration range is ≤0.1mg / m³, and the dust concentration range is ≤10mg / m³. The control panel's various control operating environments are obtained based on the specified rules. See Table 1 for details.

[0054] Table 1. Several groups of control panel working environments

[0055]

[0056] It should be noted that the above-mentioned method of setting the control panel's various groups of control working environments uses a moderate gradient to ensure that the values ​​of the environmental variables are evenly distributed, which can systematically cover the entire safety range and reduce accidental errors. Taking values ​​in sequence from low to high helps to observe linear changes or nonlinear mutations of the control panel.

[0057] Samples are taken from the control boards of the same production batch and powered on to run benchmark tests under each group of control working environments. The performance parameters under each group of control working environments are obtained and recorded as each group of control performance parameters of the control board. The performance parameters include electrical performance parameters, functional parameters, and reliability parameters.

[0058] The environmental adaptability test module tests the performance parameters of the control board under various working environments, and compares them with the control performance parameters and performance parameter standards to obtain scores of the electrical performance indicators, functional indicators, and reliability indicators of the control board under various working environments.

[0059] Further, see Figure 3 As shown, the specific working process of the environmental adaptability test module includes: extracting a set number of samples from the control boards of the same production batch to test their electrical performance parameters, functional parameters, and reliability parameters in a working environment with a temperature label, wherein the electrical performance parameters include voltage, current, insulation resistance, power consumption, and efficiency; the functional parameters include key response time, screen display quality, control instruction response time, communication transmission speed, and sensor input signal response time; and the reliability parameters include the number of failures such as overheating, freezing, restarting, false triggering, short circuit, leakage, sensor failure, and communication interruption.

[0060] As a preferred solution, the screen display quality is evaluated by integrating the brightness, contrast and integrity of the control panel screen display.

[0061] Furthermore, the specific working process of the environmental adaptability test module also includes: screening each group of control electrical performance parameters of the control board from each group of control performance parameters of the control board.

[0062] The electrical performance parameters of each sample in the working environment with a temperature label are compared with the electrical performance parameters of each group of controls to obtain the deviation of each sub-item of the electrical performance parameters of each sample in the working environment with a temperature label relative to each control group. The mode of the deviation of the electrical performance parameter sub-item relative to each control group is used as the deviation of the electrical performance parameter sub-item relative to the control group. The deviation of each sub-item of the electrical performance parameter of each sample relative to the control group is further obtained. The deviation is input into a preset electrical performance parameter deviation-first evaluation coefficient relationship model to output the first electrical performance evaluation coefficient of each sample in the corresponding temperature environment. The relationship model includes a quantitative mapping relationship between the electrical performance parameter deviation and the evaluation coefficient.

[0063] As a preferred solution, the smaller the deviation of each sub-item of the electrical performance parameter relative to the control group, the larger the first evaluation coefficient of the electrical performance.

[0064] It should be noted that the electrical performance of the control board in a control working environment will be better than the electrical performance in an environment with a temperature label. In this scenario, the closer the electrical performance parameters of the control board sample in the working environment with a temperature label are to the electrical performance parameters of the control board in the control working environment, the better the electrical performance of the control board sample in the working environment with a temperature label.

[0065] Furthermore, the specific working process of the environmental adaptability test module also includes: screening standard values ​​of electrical performance parameters from the control panel performance parameter standards stored in the database.

[0066] The electrical performance parameters of each sample under the working environment with a temperature label are compared with the corresponding standard values ​​to obtain the deviation of each sub-item of the electrical performance parameters of each sample under the corresponding temperature environment relative to the performance parameter standard. The deviation is input into the preset electrical performance parameter deviation-second evaluation coefficient relationship model to output the second evaluation coefficient of the electrical performance of each sample under the corresponding temperature environment.

[0067] The first evaluation coefficient and the second evaluation coefficient of the electrical performance of each sample in the working environment with the temperature label are comprehensively calculated according to the preset rules to generate the electrical performance evaluation index of each sample in the temperature environment.

[0068] As a preferred solution, the smaller the deviation of each sub-item of the electrical performance parameter relative to the performance parameter standard, the larger the second evaluation coefficient of the electrical performance.

[0069] It should be noted that the electrical performance of the control board in an operating environment with a temperature label will be lower than the electrical performance standard of the control board. In this scenario, the closer the electrical performance parameters of the control board sample in an operating environment with a temperature label are to the standard values, the better the electrical performance of the control board sample in the operating environment with a temperature label.

[0070] In one specific embodiment, a weighted average of the first and second electrical performance evaluation coefficients of each sample in an operating environment with a temperature label is calculated to obtain an electrical performance evaluation index for each sample in an operating environment with a temperature label. The weights of the first and second electrical performance evaluation coefficients are set values, and their cumulative sum is 1.

[0071] Furthermore, the specific working process of the environmental adaptability test module also includes: setting a relationship comparison table between the electrical performance evaluation index range and the electrical performance index score, and matching the electrical performance index score of each sample under the temperature environment according to the electrical performance evaluation index of each sample under the working environment with a temperature label.

[0072] Similarly, obtain the scores of functional indicators and reliability indicators of each sample under the temperature environment.

[0073] As a preferred solution, the method for obtaining the functional index and reliability index scores of each sample in the working environment with a temperature label is based on the same principle as the method for obtaining the electrical performance index scores of each sample in the working environment with a temperature label.

[0074] Furthermore, the specific working process of the environmental adaptability test module also includes: extracting a set number of samples from the control boards of the same production batch to test the electrical performance parameters, functional parameters, and reliability parameters of the samples in a working environment with labels of relative humidity, voltage fluctuation ratio, mechanical vibration frequency, salt spray concentration, and dust concentration, and analyzing the scores of the electrical performance indicators, functional indicators, and reliability indicators of each sample under various working environments.

[0075] As a preferred solution, the method for analyzing the electrical performance indicators, functional indicators, and reliability indicators of each sample in a working environment with labels of relative humidity, voltage fluctuation ratio, mechanical vibration frequency, salt spray concentration, and dust concentration has the same principle as the method for analyzing the electrical performance indicators, functional indicators, and reliability indicators of each sample in a working environment with labels of temperature.

[0076] As a preferred solution, the number of control panel samples tested under various working environments may be the same or different.

[0077] The performance qualification evaluation module determines the qualification of the control board based on the scoring results of the control board, and calculates the failure rate of the electrical performance, function and reliability of the control board under various working environments.

[0078] Furthermore, the specific working process of the performance qualification evaluation module is: setting scoring thresholds for electrical performance indicators, functional indicators, and reliability indicators.

[0079] The scores of the electrical performance indicators, functional indicators, and reliability indicators of each sample in the working environment with a temperature label are compared with the corresponding scoring thresholds. If the scores of the electrical performance indicators, functional indicators, and reliability indicators of a sample in the temperature environment are greater than or equal to the corresponding scoring thresholds, the sample is qualified; otherwise, the sample is unqualified, and the non-compliant indicator items are obtained.

[0080] The ratio of the number of unqualified samples that do not meet the electrical performance indicators, functional indicators, and reliability indicators under the temperature environment to the total number of samples tested under the temperature environment is counted to obtain the failure rate of the electrical performance, function, and reliability of the control board under the temperature environment.

[0081] Similarly, obtain the failure rate of the electrical performance, function, and reliability of the control board under various other working environments.

[0082] It should be noted that the present invention provides a unified benchmark for performance testing in different environments by setting a reference working environment and running benchmark tests. It combines international / industry standard parameters to achieve standardized comparison of test results, ensure the objectivity and comparability of the evaluation process, and provide a scientific basis for quality control.

[0083] The environmental sensitivity analysis module evaluates the control panel's sensitivity ranking to the working environment and the ranking of the degree of influence of the working environment on the indicators, and obtains an environmental sensitivity analysis result of the control panel.

[0084] Furthermore, the specific working process of the environmental sensitivity analysis module is as follows: S1: sorting the failure rates of the electrical performance, function, and reliability of the control board in the working environment with the temperature label from high to low to obtain the ranking of the degree of influence of the temperature environment on each indicator.

[0085] Similarly, we can obtain the ranking of the impact of various other working environments on various indicators.

[0086] S2: Accumulate the failure rates of the electrical performance, function, and reliability of the control board under the working environment with the temperature label to obtain the comprehensive failure rate of the control board under the temperature environment.

[0087] Similarly, the comprehensive failure rate of the control board under various other working environments is obtained.

[0088] Various working environments are sorted from high to low according to the comprehensive failure rate of the control board in the environment, and the sensitivity ranking of the control board to various working environments is obtained.

[0089] It should be noted that the present invention can guide enterprises to prioritize improving adaptability to highly sensitive environments and taking corresponding measures by ranking the degree of impact of different environments on the performance of the control panel and clarifying the types of sensitive environments and key weak indicators, thereby improving the overall reliability of the product.

[0090] The database stores the safety range of environmental variables and the control panel performance parameter standards.

[0091] It should be noted that the safe range of environment variables refers to the numerical range of the corresponding environment variables within which the control board can operate stably. It can be obtained by checking product manuals and technical documents, referring to similar product experience, and environmental testing.

[0092] It should be noted that the performance parameter standards of the control panel are set based on international standards and industry practices, and can be obtained from the product specifications of the control panel manufacturer.

[0093] The above contents are merely examples and explanations of the concept of the present invention. Those skilled in the art may make various modifications or additions to the described specific embodiments or replace them in a similar manner. As long as they do not deviate from the concept of the invention or exceed the scope defined by the present invention, they should all fall within the scope of protection of the present invention.
