[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, rather than 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 of the present invention belong to the scope of protection of the present invention.

[0023] Please refer to Figure 1 As shown, the present invention provides an intelligent monitoring and analysis method for the performance of a range hood control panel, which includes: Step 1. Monitoring the operation performance of the range hood: Monitor the operation performance information of the range hood control panel, and the operation performance information includes each use response duration and button image.

[0024] It should be added that the process of obtaining each use response duration of the range hood control panel: Monitor through a high-precision touch sensor installed in the touch sensing area of the range hood control panel. When the user touches the panel, the touch sensor immediately senses the signal and triggers the connected timing module to start timing. Then, when the range hood performs the corresponding operation, the feedback signal triggers the timing module to stop timing again, so as to obtain each use response duration of the range hood control panel.

[0025] It should be added that the button image of the range hood control panel is obtained by shooting with a camera installed above the range hood control panel.

[0026] Step 2. Analysis of the operating performance of the range hood: According to the operating performance information of the range hood control panel, analyze the qualified index η1 of the operating performance of the range hood control panel.

[0027] Please refer to Figure 2 As shown, exemplarily, the analysis of the qualified index of the operating performance of the range hood control panel includes: W1. According to the usage response time of each part of the range hood control panel, count the qualified index δ1 of the response time of the range hood control panel.

[0028] Further, the counting of the qualified index of the response time of the range hood control panel includes: W1-1. Select the maximum value from the usage response times of each part of the range hood control panel as the maximum usage response time of the range hood control panel, and denote it as T max .

[0029] W1-2. Calculate the average value of the usage response times of each part of the range hood control panel, and take the calculation result as the average usage response time of the range hood control panel, denoted as

[0030] W1-3. Count the qualified index δ1 of the response time of the range hood control panel, where T′ is the set reference usage response time.

[0031] It should be added that T′ is extracted from the technical specification table for the performance analysis of the range hood control panel.

[0032] W2. According to the button images of the range hood control panel, count the qualified index δ2 of the operation convenience of the range hood control panel.

[0033] Further, the counting of the qualified index of the operation convenience of the range hood control panel includes: W2-1. Locate the distances between the center points of each button and the center points of its adjacent buttons from the button images of the range hood control panel.

[0034] In a specific embodiment, assume that we have a range hood control panel with a total of 5 buttons, numbered button 1, button 2, button 3, button 4, and button 5 respectively.

[0035] Obtain the key images of the range hood control panel through an image acquisition device, and use image analysis software to locate the center points of each key. Suppose the obtained center point coordinates are as follows: the center point coordinates of key 1 are (x1, y1), the center point coordinates of key 2 are (x2, y2), the center point coordinates of key 3 are (x3, y3), the center point coordinates of key 4 are (x4, y4), and the center point coordinates of key 5 are (x5, y5). Among them, the adjacent key to key 1 is key 2, the adjacent keys to key 2 are key 1 and key 3, the adjacent keys to key 3 are key 2 and key 4, the adjacent keys to key 4 are key 3 and key 5, and the adjacent key to key 5 is key 4.

[0036] Calculate the distances between the center points of each key and the center points of its adjacent keys. For example, the distance d between key 1 and key 2 12 can be calculated by the following formula: And so on, calculate the distances d between the center points of each key and the center points of its respective adjacent keys 23 、d 34 and d 45 .

[0037] W2 - 2. If the distance between the center point of a certain key and the center point of its adjacent key is within the set reference key distance range, then mark this key and its adjacent key as a distance - qualified key group, and count the number of distance - qualified key groups.

[0038] W2 - 3. Combine the key and its adjacent key to form a key group, count the number of key groups, and take the ratio of the number of distance - qualified key groups as the operation convenience qualified index of the range hood control panel, denoted as δ2.

[0039] In a specific embodiment, assume that the set distance range is [2 cm, 4 cm]. If d 12 is within the range of [2 cm, 4 cm], then key 1 and key 2 are marked as a distance - qualified key group. Suppose after judgment, the following key combinations are marked as distance - qualified key groups: key 1 and key 2, key 2 and key 3. Then the number of distance - qualified key groups is 2. If the number of key groups is 4, and the statistical operation convenience qualified index = the number of distance - qualified key groups ÷ the number of key groups, then

[0040] W3. Calculate the average value of the response duration qualified index and the operation convenience qualified index of the range hood control panel, and then take the calculation result as the operation performance qualified index of the range hood control panel, denoted as η1.

[0041] In an embodiment of the present invention, by analyzing the operation performance qualification index of the range hood control panel based on the response duration qualification index and the operation convenience qualification index of the range hood control panel, the deficiency in the current analysis of the operation convenience of the range hood control panel is broken, thereby ensuring the accuracy of the operation performance analysis of the range hood control panel and at the same time ensuring the timeliness of discovering potential operation problems.

[0042] Step 3: Monitor the stability performance of the range hood: Monitor the stability performance information of the range hood control panel, where the stability performance information includes anti-interference information and working stability information.

[0043] It should be added that the anti-interference information of the range hood control panel includes: the number of key response failures, the number of display clarity failures, the number of function switching failures, and the total number of uses of the range hood control panel under various electromagnetic interference intensities, various temperatures, and various humidities.

[0044] It should be added that the method for obtaining the number of key response failures, the number of display clarity failures, the number of function switching failures, and the total number of uses of the range hood control panel under various electromagnetic interference intensities: Detect the electromagnetic interference intensity near the range hood control panel through an electromagnetic interference sensor installed near the range hood control panel. At the same time, connect the key circuit of the range hood control panel to a data acquisition system, and then use devices such as a microcontroller or a data acquisition card to determine whether the key responds normally by monitoring the change in the electrical signal generated when the key is pressed. And through the monitoring software, when the data acquisition system detects the key press signal but the range hood does not have the corresponding action, the software will record a key response failure.

[0045] It should be added that the method for obtaining the number of display clarity failures of the range hood control panel under various electromagnetic interference intensities: Set a high-definition camera or an image sensor in front of the range hood control panel, aiming at the display area of the range hood control panel. The camera can capture the display content in real time and transmit the image to a computer for analysis. Then use image analysis software to process the captured image to determine whether the display is clear. For example, the contrast, brightness, and resolution of the image can be detected, and then the contrast of the image is matched and compared with the contrast intervals corresponding to each contrast score to obtain the contrast score of the image. And the brightness score and resolution score of the image are obtained in the same way as the matching method of the contrast score of the image.

[0046] Sum up the contrast score, brightness score, and resolution score of the image, and use the sum result as the image display quality. When the image display quality is less than the set reference image display quality, record a display clarity failure.

[0047] It should be added that the method for obtaining the number of function switching failures of the range hood control panel under different electromagnetic interference intensities is as follows: Connect the function switching circuit of the range hood control panel to the data acquisition system, monitor the signal changes generated during function switching. When the user operates the control panel for function switching, the data acquisition system detects the switching signal and records it. At the same time, verify whether the function switching is successful by observing the actual function changes of the range hood. If the data acquisition system detects a function switching signal, but the range hood does not correctly switch to the corresponding function mode, record one function switching failure.

[0048] It should be added that the method for obtaining the total number of uses of the range hood control panel under different electromagnetic interference intensities is as follows: Integrate a counter into the circuit of the range hood control panel, and then implement it through software or hardware. Whenever the user operates the control panel, whether it is a button press, function switching or other operations, the counter increments by one, so as to accurately record the total number of uses of the control panel.

[0049] It should be added that the method for obtaining the number of button response failures, display clarity failures, function switching failures and total number of uses of the range hood control panel under different temperatures and humidities is as follows: Monitor the temperature and humidity near the range hood control panel through temperature sensors and humidity sensors installed around the range hood control panel respectively. Then, in the same way as the above-mentioned obtaining methods, obtain the number of button response failures, display clarity failures, function switching failures and total number of uses of the range hood control panel under different temperatures and humidities.

[0050] Step Four: Analysis of the stability performance of the range hood: Analyze the stability performance qualification index η2 of the range hood control panel according to the stability performance information of the range hood control panel.

[0051] Exemplarily, the analysis of the stability performance qualification index of the range hood control panel includes: S1. According to the anti-interference information of the range hood control panel, count the anti-interference qualification index of the range hood control panel

[0052] Furthermore, the counting of the anti-interference qualification index of the range hood control panel includes: S1-1. Extract the number of button response failures, display clarity failures, function switching failures and number of uses of the range hood control panel under different electromagnetic interference intensities from the anti-interference information of the range hood control panel. Then, count the total number of button response failures, total number of display clarity failures, total number of function switching failures and total number of uses of the range hood control panel under electromagnetic interference, and record them as D1, D2, D3 and D′ respectively.

[0053] S1-2. Count the anti-electromagnetic interference qualification index ψ1 of the range hood control panel Let z1, z2, and z3 be the weights of the set key response qualification index, display clarity qualification index, and function switching qualification index respectively, where z1 + z2 + z3 = 1, and z1 > z2 > z3.

[0054] It should be added that the key response is directly related to the basic operation control of the range hood by the user. If the key fails to respond in a timely manner or gives an incorrect response under electromagnetic interference, it will greatly affect the user experience and satisfaction with the product. The display clarity allows the user to intuitively understand information such as the working status and set parameters of the range hood. Although it is also important, its direct impact on user operation is relatively smaller compared to the key response. Function switching is not an operation that users frequently perform in daily use. Moreover, in some cases, even if the function switching is interfered to a certain extent, users may still be able to achieve the required function through other means (such as re - operating or waiting for the interference to disappear). Therefore, z1 > z2 > z3 is set. Specifically, z1 can be set to 0.5, z2 can be set to 0.3, and z3 can be set to 0.2.

[0055] In a specific embodiment, assume that the total number of electromagnetic interference times is 100 times, the key response fails 4 times, the display clarity fails 2 times, and the function switching fails 3 times.

[0056] The anti - electromagnetic interference qualification index of the range hood control panel = (1 - 4 / 100)×0.5+(1 - 2 / 100)×0.3+(1 - 3 / 100)×0.2 = 0.96×0.5 + 0.98×0.3 + 0.97×0.2 = 0.968.

[0057] S1 - 3: Extract the number of key response failures, display clarity failures, function switching failures, and total usage times of the range hood control panel at each temperature and each humidity from the anti - interference information of the range hood control panel. Then, in the same way as the statistical method of ψ1, statistically calculate the anti - temperature interference qualification index and anti - humidity interference qualification index of the range hood control panel, and denote them as ψ2 and ψ3 respectively.

[0058] In a specific embodiment, assume that the total number of temperature interference times is 100 times, the key response fails 3 times, the display clarity fails 1 time, and the function switching fails 2 times.

[0059] The anti - temperature interference qualification index of the range hood control panel = (1 - 3 / 100)×0.5+(1 - 1 / 100)×0.3+(1 - 2 / 100)×0.2 = 0.97×0.5 + 0.99×0.3 + 0.98×0.2 = 0.978.

[0060] In a specific embodiment, assume that the total number of humidity interference times is 100 times, the key response fails 2 times, the display clarity fails 2 times, and the function switching fails 1 time.

[0061] The humidity interference resistance qualification index of the range hood control panel = (1 - 2 / 100) × 0.5 + (1 - 2 / 100) × 0.3 + (1 - 1 / 100) × 0.2 = 0.98 × 0.5 + 0.98 × 0.3 + 0.99 × 0.2 = 0.982.

[0062] In the embodiment of the present invention, by analyzing the electromagnetic interference resistance qualification index of the range hood control panel according to the weights of the set key response qualification index, display clarity qualification index, and function switching qualification index, the performance of the range hood control panel in terms of electromagnetic interference resistance is comprehensively evaluated by multiple indicators, avoiding the one-sidedness of single-index evaluation, thereby improving the comprehensiveness of the evaluation of the range hood control panel. At the same time, by setting the weights, the accuracy of reflecting the true performance of the range hood control panel in various electromagnetic interference environments is improved.

[0063] S1-4. Statistically analyze the interference resistance qualification index of the range hood control panel ψ1′, ψ2′, and ψ3′ are respectively the electromagnetic interference resistance qualification index, temperature interference resistance qualification index, and humidity interference resistance qualification index set as references.

[0064] It should be added that ψ1′, ψ2′, and ψ3′ are all extracted from the technical specification table for the performance analysis of the range hood control panel.

[0065] S2. Extract the maximum temperature of the range hood control panel during each use from the working stability information of the range hood control panel.

[0066] S3. Compare the maximum temperature of the range hood control panel during each use with the set reference temperature threshold.

[0067] S4. If the maximum temperature of the range hood control panel during a certain use is less than the set reference temperature threshold, then record this use of the range hood control panel as a temperature-qualified use, and then statistically analyze the number of temperature-qualified uses, and take the ratio of it to the number of uses as the temperature qualification ratio of the range hood control panel, denoted as λ.

[0068] S5. Extract the number of failures and the total usage duration of the range hood control panel within the set usage period from the working stability information of the range hood control panel.

[0069] S6. Take the ratio of the number of failures to the total usage duration as the failure rate of the range hood control panel, denoted as

[0070] In a specific embodiment, the formula for the failure incidence rate is: failure incidence rate = number of failures ÷ usage time (in hours). For example, if during a three - month monitoring period, the control panel has 5 failures, and the range hood is used for 2 hours per day on average, then the usage time is 3×30×2 = 180 hours, and the failure incidence rate = 5÷180×≈2.78%.

[0071] S7. Statistically analyze the working stability qualification index of the range hood control panel λ′ and are respectively the temperature qualification ratio and the failure incidence rate set as references, and e is the natural constant.

[0072] It should be added that λ′ and are both extracted from the technical specification table for the performance analysis of the range hood control panel.

[0073] S8. Import and into the stability performance qualification index judgment model to obtain the stability performance qualification index of the range hood control panel, denoted as η2.

[0074] It should be added that the judgment process of the stability performance qualification index judgment model: when , take the anti - interference qualification index of the range hood control panel as the stability performance qualification index of the range hood control panel; when , take the working stability qualification index of the range hood control panel as the stability performance qualification index of the range hood control panel.

[0075] Step Five. Safety performance monitoring of the range hood: Monitor the safety performance information of the range hood control panel. The safety performance information includes the insulation resistance at each monitoring time point, as well as the control panel image of the range hood, the number of times the buttons get stuck during use, and the total number of times the buttons are used.

[0076] It should be added that the insulation resistance of the range hood control panel at each monitoring time point is monitored by an insulation resistance tester installed on the range hood control panel.

[0077] It should be added that the control panel image of the range hood control panel is captured by a camera installed above the range hood control panel.

[0078] It should be added that the method for obtaining the number of times the buttons on the range hood control panel are used with jamming and the total number of times the buttons are used: Connect a monitoring device to the button circuit of the range hood control panel. When the user presses a button, the monitoring device will collect the signal changes in the button circuit in real time, and then analyze and process the collected signals to determine whether the button is pressed, the length of time it is pressed, and the stability of the signal, etc. Thus, according to the preset judgment criteria, the data processing unit will judge whether the button operation is jammed. For example, if the change process of the signal is discontinuous or there are abnormal fluctuations, and this situation lasts for more than a certain threshold, it is considered that jamming has occurred. Each time jamming occurs, the jamming times counter will increase, and at the same time, the total button usage times counter will also increase accordingly.

[0079] Step Six: Analysis of the safety performance of the range hood: Analyze the safety performance qualification index η3 of the range hood control panel according to the safety performance information of the range hood control panel.

[0080] Please refer to Figure 3 As shown, exemplarily, the analysis of the safety performance qualification index of the range hood control panel includes: F1. According to the insulation resistance of the range hood control panel at each monitoring time point, count the electrical performance qualification index l1 of the range hood control panel.

[0081] Further, the counting of the electrical performance qualification index of the range hood control panel includes: F1-1. Combine each monitoring time point with its next monitoring time point to obtain each monitoring time group.

[0082] F1-2. If the front insulation resistance and the rear insulation resistance in a certain monitoring time group are respectively denoted as α1 and α2.

[0083] F1-3. Count the insulation resistance change rate μ of this monitoring time group, and then obtain the insulation resistance change rates of each monitoring time group.

[0084] F1-4. If the absolute value of the insulation resistance change rate of a certain monitoring time group is less than the absolute value of the set reference insulation resistance change rate, then mark this monitoring time group as a qualified monitoring time group, and count the number of qualified monitoring time groups and the number of monitoring time groups.

[0085] F1-5. Take the ratio of the number of qualified monitoring time groups to the number of monitoring time groups as the electrical performance qualification index of the range hood control panel, denoted as l1.

[0086] F2. According to the control panel image, the number of times the buttons on the range hood control panel are used with jamming, and the total number of times the buttons are used, count the mechanical performance qualification index l2 of the range hood control panel.

[0087] Further, the method for statistically analyzing the mechanical performance qualification index of the range hood control panel includes: F2-1. Extract the number of scratches and the length of each scratch on the range hood control panel from the panel image of the range hood control panel, and then screen out the maximum scratch length therefrom, denoted as L. max .

[0088] It should be added that the method for obtaining the number of scratches and the length of each scratch on the range hood control panel is as follows: Import the panel image into an image editing software or a dedicated image analysis software, and then use functions such as zooming and contrast adjustment of the software to more clearly display the scratches, automatically detect and count the scratches, and measure the length of the scratches, so as to obtain the number of scratches and the length of each scratch on the range hood control panel.

[0089] F2-2. Calculate the average value of the lengths of each scratch on the range hood control panel to obtain the average scratch length of the range hood control panel, denoted as And denote the number of scratches on the range hood control panel as D″.

[0090] F2-3. Statistically analyze the appearance qualification index ξ1 of the range hood control panel. D″′ and L′ are respectively the set permitted number of scratches and the permitted scratch length.

[0091] F2-4. Extract the number of times the buttons on the range hood control panel are stuck during use and the total number of times the buttons are used from the mechanical performance information of the range hood control panel, and denote them as ω1 and ω2 respectively.

[0092] F2-5. Statistically analyze the mechanical qualification index ξ2 of the range hood control panel.

[0093] F2-6. Statistically analyze the mechanical performance qualification index l2, where l2 = min(ξ1, ξ2).

[0094] F3. Screen out the minimum value from the electrical performance qualification index and the mechanical performance qualification index of the range hood control panel as the safety performance qualification index of the range hood control panel, and denote it as η3.

[0095] In the embodiment of the present invention, by analyzing the safety performance qualification index of the range hood control panel based on the electrical performance qualification index and the mechanical performance qualification index of the range hood control panel, the comprehensiveness of the safety performance analysis of the range hood control panel is improved, thereby improving the quality qualification of the range hood control panel.

[0096] Step Seven. Range hood performance qualification analysis: Analyze the performance qualification index of the range hood control panel according to the operation performance qualification index, the stability performance qualification index, and the safety performance qualification index of the range hood control panel.

[0097] Exemplarily, analyzing the performance qualification index of the range hood control panel includes: extracting the operation performance qualification index η1, the stability performance qualification index η2, and the safety performance qualification index η3 of the range hood control panel.

[0098] Statistical performance qualification index of the range hood control panel r1, r2, and r3 are the weights of the set operation performance qualification index, stability performance qualification index, and safety performance qualification index respectively, r1 + r2 + r3 = 1, and r3 > r2 > r1.

[0099] It should be added that safety is the primary consideration for any electrical product. If there are safety hazards in the range hood control panel, it may lead to serious consequences such as electric shock and fire, posing a direct threat to the life and property safety of users. The stability performance determines the reliability of the range hood during use. If the control panel is unstable, problems such as frequent failures, crashes, and misoperations may occur, affecting the normal use experience of users. The operation performance mainly affects the convenience and comfort of users in using the product. Although good operation performance can improve the user experience, its importance is relatively low compared to safety and stability performance. Therefore, r3 > r2 > r1 is set. For the convenience of analysis, r1 can be specifically set to 0.2, r2 can be specifically set to 0.3, and r3 can be specifically set to 0.5.

[0100] In the embodiment of the present invention, by analyzing the performance of the range hood control panel from three dimensions: operation performance, stability performance, and safety performance, the problem of insufficient attention to the stability performance and safety performance of the current range hood control panel is avoided, and comprehensive performance analysis is realized according to the operation performance, stability performance, and safety performance of the range hood control panel. Furthermore, the accuracy of the performance analysis of the range hood control panel is ensured, thereby improving the comprehensiveness of the performance analysis of the range hood control panel, and thus ensuring and improving the reliability of the performance analysis of the range hood control panel.
