[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] See also Figure 1 As shown, the present invention provides a method for intelligent monitoring and analysis of range hood control panel performance, the method comprising: step one, range hood operation performance monitoring: range hood operation performance monitoring: monitoring the operation performance information of the range hood control panel, the operation performance information including each use response duration and button image.

[0024] It should be added that the process of obtaining the response time of each use of the range hood control panel is: monitored by 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 timing module connected to it to start timing. Then, when the range hood performs the corresponding operation, the feedback signal triggers the timing module again to stop timing, thereby obtaining the response time of each use of the range hood control panel.

[0025] It should be added that the button images of the range hood control panel are captured by a camera placed above the range hood control panel.

[0026] Step 2: Analysis of range hood operating performance: Analyze the operating performance qualification index η1 of the range hood control panel based on the operating performance information of the range hood control panel.

[0027] See also Figure 2 As shown, exemplarily, the analysis of the operating performance qualification index of the range hood control panel includes: W1, according to each use response time of the range hood control panel, calculating the response time qualification index δ1 of the range hood control panel.

[0028] Furthermore, the statistical response time qualification index of the range hood control panel includes: W1-1, selecting the maximum value from the response times of the range hood control panel as the maximum response time of the range hood control panel, and recording it as T max .

[0029] W1-2, calculate the average response time of each range hood control panel, and use the result as the average response time of the range hood control panel, recorded as

[0030] W1-3, calculate the qualified index δ1 of the response time of the range hood control panel, T' is the usage response time of the setting reference.

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

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

[0033] Furthermore, the statistical operation convenience qualified index of the range hood control panel includes: W2-1, locating the distance between the center point of each button and the center points of its adjacent buttons in the button image of the range hood control panel.

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

[0035] The button images of the range hood control panel are obtained through an image acquisition device, and the center point of each button is located using image analysis software. It is assumed that the center point coordinates are as follows: the center point coordinates of button 1 are (x1, y1), the center point coordinates of button 2 are (x2, y2), the center point coordinates of button 3 are (x3, y3), the center point coordinates of button 4 are (x4, y4), and the center point coordinates of button 5 are (x5, y5), where the adjacent key of button 1 is button 2, the adjacent keys of button 2 are button 1 and button 3, the adjacent keys of button 3 are button 2 and button 4, the adjacent keys of button 4 are button 3 and button 5, and the adjacent key of button 5 is button 4.

[0036] Calculate the distance between the center point of each key and the center point of its adjacent key, for example, the distance d between key 1 and key 2 12 It can be calculated by the following formula: Similarly, calculate the distance d between the center point of each key and the center point of each adjacent key 23 d 34 and d 45 .

[0037] W2-2. If the distance between a key center point and a certain adjacent key center point is within a set reference key distance interval, the key and the adjacent key are recorded as a key group with qualified distance, and the number of key groups with qualified distance is counted.

[0038] W2-3. Group the buttons with their adjacent buttons into button groups, count the number of button groups, and use the ratio of the distance to the number of qualified button groups as the qualified index of convenient operation of the range hood control panel, recorded as δ2.

[0039] In a specific embodiment, assuming that the set distance interval is [2 cm, 4 cm], if d 12 If the distance between the two buttons is within the interval of [2 cm, 4 cm], then button 1 and button 2 are recorded as the qualified distance button group. Assuming that after judgment, the following button combinations are recorded as qualified distance button groups: button 1 and button 2, button 2 and button 3, then the number of qualified distance button groups is 2. If the number of button groups is 4, the statistical operation convenience qualified index = the number of qualified distance button groups ÷ the number of button groups, then

[0040] W3. Calculate the average of the response time qualification index and the operation convenience qualification index of the range hood control panel, and then use the calculation result as the operation performance qualification index of the range hood control panel, and record it as η1.

[0041] The embodiment of the present invention analyzes the operational performance qualification index of the range hood control panel according to the response time qualification index and the operational convenience qualification index of the range hood control panel, thereby breaking the current shortcomings of the operational convenience analysis of the range hood control panel, thereby ensuring the accuracy of the operational performance analysis of the range hood control panel and ensuring the timeliness of the discovery of potential operational problems.

[0042] Step 3: Range hood stability performance monitoring: monitor the stability performance information of the range hood control panel, which 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 button 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, temperatures and humidities.

[0044] It should be added that the number of button response failures, display clarity failures, function switching failures and total usage times of the range hood control panel under various electromagnetic interference intensities are obtained by: detecting the electromagnetic interference intensity near the range hood control panel through an electromagnetic interference sensor placed near the range hood control panel, and connecting the button circuit of the range hood control panel to the data acquisition system, and then using a microcontroller or data acquisition card and other devices to monitor the changes in the electrical signal generated when the button is pressed to determine whether the button responds normally, and through the monitoring software, when the data acquisition system detects a button press signal but the range hood does not have a corresponding action, the software will record a button 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 is as follows: a high-definition camera or image sensor is set in front of the range hood control panel and aimed 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, and then use image analysis software to process the collected image to determine whether the display is clear. For example, the image contrast, brightness, resolution and other parameters can be detected, and then the image contrast can be matched and compared with the contrast intervals corresponding to each contrast score to obtain the image contrast score, and the image brightness score and resolution score can be matched in the same way as the image contrast score.

[0046] The contrast score, brightness score and resolution score of the image are summed up, and the sum result is used as the image display quality. When the image display quality is less than the set reference image display quality, a display clarity failure is recorded.

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

[0048] It should be added that the total number of times the range hood control panel is used under various electromagnetic interference intensities is obtained by integrating a counter in the circuit of the range hood control panel, and then implementing it through software or hardware. Every time the user operates the control panel, whether it is pressing a button, switching functions or other operations, the counter increases by one count, thereby accurately recording the total number of times the control panel is used.

[0049] It should be added that the number of button response failures, display clarity failures, function switching failures and total usage times of the range hood control panel at various temperatures and humidities are obtained by respectively monitoring the temperature and humidity near the range hood control panel through temperature sensors and humidity sensors installed around the range hood control panel, and then obtaining the number of button response failures, display clarity failures, function switching failures and total usage times of the range hood control panel at various temperatures and humidities in the same way as above.

[0050] Step 4: Range hood stability performance analysis: Analyze the stability performance qualification index η2 of the range hood control panel based on the stability performance information of the range hood control panel.

[0051] Exemplarily, the analysis of the stability performance qualified index of the range hood control panel includes: S1, according to the anti-interference information of the range hood control panel, calculating the anti-interference qualified index of the range hood control panel

[0052] Furthermore, the statistical anti-interference qualified index of the range hood control panel includes: S1-1, extracting the number of key response failures, display clarity failures, function switching failures and usage times of the range hood control panel under various electromagnetic interference intensities from the anti-interference information of the range hood control panel, and then counting the total number of key response failures, display clarity failures, function switching failures and usage times of the range hood control panel under electromagnetic interference, and recording them as D1, D2, D3 and D′ respectively.

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

[0054] It should be added that the button response is directly related to the user's basic operational control of the range hood. If the button does not respond in time or responds incorrectly under electromagnetic interference, it will greatly affect the user's experience and satisfaction with the product. The display clarity allows the user to intuitively understand the working status, setting parameters and other information of the range hood. Although it is also very important, its direct impact on user operation is slightly smaller than that of the button response. Function switching is relatively not an operation that users perform frequently in daily use. In some cases, even if the function switching is subject to a certain degree of interference, the user may still be able to achieve the desired function through other methods (such as re-operation or waiting for the interference to disappear). Therefore, z1>z2>z3 is set, and z1 can be specifically taken as 0.5, z2 can be specifically taken as 0.3, and z3 can be specifically taken as 0.2.

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

[0056] The anti-electromagnetic interference qualified 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 button response failures, display clarity failures, function switching failures and total usage times of the range hood control panel at various temperatures and humidities from the anti-interference information of the range hood control panel, and then calculate the temperature interference resistance qualification index and humidity interference resistance qualification index of the range hood control panel in the same way as ψ1, and record them as ψ2 and ψ3 respectively.

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

[0059] The temperature interference resistance qualified 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, it is assumed that the total number of humidity interferences 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 qualified 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] The embodiment of the present invention analyzes the anti-electromagnetic interference qualified index of the range hood control panel according to the set weights of the button response qualified index, the display clarity qualified index and the function switching qualified index. Multiple indicators are used to comprehensively evaluate the performance of the range hood control panel in anti-electromagnetic interference, thereby avoiding the one-sidedness of a single indicator evaluation, thereby improving the comprehensiveness of the evaluation of the range hood control panel. At the same time, by setting weights, the accuracy of reflecting the actual performance of the range hood control panel in various electromagnetic interference environments is improved.

[0063] S1-4. Count the anti-interference qualified index of the range hood control panel ψ1′, ψ2′ and ψ3′ are respectively set reference anti-electromagnetic interference qualified index, anti-temperature interference qualified index and anti-humidity interference qualified index.

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

[0065] S2. extracting 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 each time it is used with a set reference temperature threshold.

[0067] S4. If the maximum temperature of the range hood control panel during a certain use is lower than the set reference temperature threshold, the use of the range hood control panel at that time is recorded as a qualified use of the temperature, and then the number of qualified uses of the temperature is counted, and the ratio of the qualified use of the temperature to the number of uses is used as the qualified temperature ratio of the range hood control panel, recorded as λ.

[0068] S5. Extracting the number of failures and the total usage time of the range hood control panel within a set usage cycle from the working stability information of the range hood control panel.

[0069] S6. The ratio of the number of failures to the total usage time is taken as the failure rate of the range hood control panel, denoted as

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

[0071] S7. Calculate the working stability qualification index of the range hood control panel λ′ and are the qualified ratio and failure rate of the set reference temperature respectively, and e is a natural constant.

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

[0073] S8. and The stability performance qualified index is introduced into the judgment model to obtain the stability performance qualified index of the range hood control panel, which is recorded as η2.

[0074] It should be added that the judgment process of the stability performance qualification index judgment model is: When the anti-interference qualified index of the range hood control panel is used as the stable performance qualified index of the range hood control panel, When the working stability qualified index of the range hood control panel is used as the stable performance qualified index of the range hood control panel.

[0075] Step 5. Range hood safety performance monitoring: 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, the number of button jams, and the total number of button usage.

[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 obtained by photographing a camera placed above the range hood control panel.

[0078] It should be added that the method for obtaining the number of times the buttons in the range hood control panel are stuck and the total number of times the buttons are used is as follows: a monitoring device is connected to the button circuit of the range hood control panel. When the user presses the 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., so that according to the preset judgment criteria, the data processing unit will determine whether the button operation is stuck. For example, if the signal change process is discontinuous or there are abnormal fluctuations, and this situation lasts for more than a certain threshold, it is considered that a jam has occurred. Each time a jam occurs, the jam count counter will increase, and the total number of button usage counter will also increase accordingly.

[0079] Step 6. Range hood safety performance analysis: Based on the safety performance information of the range hood control panel, analyze the safety performance qualification index η3 of the range hood control panel.

[0080] See also Figure 3 As shown, illustratively, 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, calculating the electrical performance qualification index l1 of the range hood control panel.

[0081] Furthermore, the statistical electrical performance qualification index of the range hood control panel includes: F1-1, combining 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 recorded as α1 and α2 respectively.

[0083] F1-3, calculate the insulation resistance change rate μ of the monitoring time group, Then the insulation resistance change rate of each monitoring time group is obtained.

[0084] F1-4. If the absolute value of the insulation resistance change rate of a monitoring time group is less than the absolute value of the insulation resistance change rate of the set reference, the monitoring time group is recorded as a qualified monitoring time group, and the number of qualified monitoring time groups and the number of monitoring time groups are counted.

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

[0086] F2. According to the control panel image, button jam times and total button usage times of the range hood control panel, calculate the mechanical performance qualification index l2 of the range hood control panel.

[0087] Furthermore, the statistical mechanical performance qualified index of the range hood control panel includes: F2-1, extracting the number of scratches on the range hood control panel and the length of each scratch from the panel image of the range hood control panel, and then screening out the maximum scratch length, which is recorded as L max .

[0088] It should be added that the number of scratches on the range hood control panel and the length of each scratch are obtained by importing the panel image into image editing software or special image analysis software, and then using the software's magnification, contrast adjustment and other functions to more clearly display the scratches while automatically detecting and counting the scratches, and measuring the length of the scratches, thereby obtaining the number of scratches on the range hood control panel and the length of each scratch.

[0089] F2-2. Calculate the average length of each scratch on the range hood control panel to obtain the average length of the scratch on the range hood control panel, which is recorded as The number of scratches on the range hood control panel is recorded as D″.

[0093] F2-6. Calculate the mechanical performance qualification index l2 of the range hood control panel, l2 = min (ξ1, ξ2).

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

[0095] The embodiment of the present invention analyzes the safety performance qualification index of the range hood control panel according to the electrical performance qualification index and mechanical performance qualification index of the range hood control panel, thereby improving the comprehensiveness of the safety performance analysis of the range hood control panel and thus improving the quality qualification of the range hood control panel.

[0096] Step 7. Range hood performance qualification analysis: Analyze the performance qualification index of the range hood control panel based on the operating performance qualification index, stability performance qualification index and safety performance qualification index of the range hood control panel.

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

[0098] Statistics on the performance qualification index of range hood control panel r1, r2 and r3 are the weights of the set operating performance qualification index, stability performance qualification index and safety performance qualification index respectively, r1+r2+r3=1, 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 user's life and property safety. Stable performance determines the reliability of the range hood during use. If the control panel is unstable, frequent failures, freezes, misoperations and other problems may occur, affecting the user's normal use experience. Operational performance mainly affects the user's convenience and comfort of using the product. Although good operational performance can improve the user's 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 taken as 0.2, r2 can be specifically taken as 0.3, and r3 can be specifically taken as 0.5.
