Description

Technical Field

[0001] The present invention relates to the technical field of intelligent cat doors, and particularly to an electronic product aging test system. Background Art

[0002] With the improvement of people's living standards and the increasing attention to pets, the pet supplies market has been continuously heating up. As an electronic product that provides convenient access for pet cats while ensuring home safety, the market demand for intelligent cat doors is growing day by day. Consumers' requirements for the quality and reliability of intelligent cat doors are also getting higher and higher. They expect to buy products with stable performance and long service life. Therefore, electronic product enterprises need a scientific and effective aging test system to ensure the quality of intelligent cat doors, meet market demands, and enhance product competitiveness.

[0003] The prior art lacks performance detection of intelligent cat doors, strict aging tests and quality evaluations, which may lead to product failures during use, affect user experience, and even damage the enterprise's brand image. Obviously, this construction method has at least the following problems: 1. The prior art lacks an effective initial test classification module and may not be able to accurately classify and test according to the models of intelligent cat doors, resulting in different models of products being tested together. This not only increases the complexity and time cost of testing, but also may affect the accuracy of test results due to mismatched test conditions, and cannot accurately reflect the true aging performance of each model of product. At the same time, there is a lack of a mechanism for dynamically adjusting test settings based on historical user feedback data. The test settings may be relatively fixed and single, and cannot be optimized according to the characteristics of different models of products and the problems that occur in actual use. This may lead to some potential quality problems not being fully detected. For example, certain models of intelligent cat doors are prone to failures in specific components, but these problems are missed in the test stage because the test settings do not cover relevant conditions, thus affecting the quality and reliability of the products.

[0004] 2. The prior art may not be able to systematically set multiple acquisition time points to comprehensively collect the mechanical performance indicators and sensor performance indicators of intelligent cat doors, and can only conduct simple and limited tests. It is impossible to obtain the performance changes of the product at different stages, and it is difficult to comprehensively and deeply evaluate the aging performance of the product, so it is impossible to accurately judge whether the product truly meets the quality requirements. The lack of scientific evaluation models such as the mechanical performance evaluation analysis model, sensor performance evaluation analysis model, and comprehensive aging performance evaluation model in the above solutions makes it difficult to quantitatively evaluate and comprehensively judge the performance of intelligent cat doors. This may lead to the quality evaluation process being too subjective and ambiguous, unable to accurately distinguish the quality grades of products, being unfavorable for the enterprise to strictly control product quality, and increasing the risk of unqualified products flowing into the market.

[0005] 3. The existing technology lacks a grading warning mechanism based on the quantity of unqualified products, and enterprises may not be able to promptly detect quality anomalies during the production process. When a large number of unqualified products occur, due to the lack of effective warning information transmission and corresponding countermeasures, the problem may be further exacerbated, increasing production losses and quality risks, and affecting the enterprise's production plan and market supply. It is impossible to accurately analyze the quality status of each model of the intelligent cat door production line, and thus it is difficult to formulate targeted maintenance plans. This may lead to a "one-size-fits-all" approach in the production line maintenance of enterprises, unable to effectively solve the actual problems of different production lines, not only wasting resources but also possibly unable to fundamentally improve the stability of the production line and product quality, affecting the production efficiency and economic benefits of the enterprise.

[0006] 4. The existing technology may not have an integrated system to collect, collate, and analyze various data related to the quality of intelligent cat doors, such as test data, user feedback data, etc., resulting in the dispersion of data in different departments and systems, making it difficult to conduct effective integration and mining. This prevents enterprises from fully utilizing these data to optimize production processes, improve product designs, and enhance the level of quality management, restricting the development and competitiveness improvement of enterprises. Due to the lack of comprehensive and accurate data support, enterprises may rely more on experience and intuition rather than objective data and analysis when making important decisions such as formulating production plans, quality control strategies, and product R & D directions. This increases the risk and uncertainty of decision-making, and may cause enterprises to miss opportunities or make wrong decisions in the market competition, affecting the long-term development of the enterprise.

At the same time, add the service life of the first mechanical failure and the service life of the first sensor failure corresponding to each user feedback of each model of intelligent cat door respectively, and then divide by the number of users who feedback the first mechanical failure and the first sensor failure respectively, so as to obtain the average service life of the first mechanical failure and the average service life of the first sensor failure corresponding to each model of intelligent cat door.

[0022] The comprehensive aging performance evaluation results of the intelligent cat door include values of 1 and -1. When the comprehensive aging performance evaluation result of a certain intelligent cat door in a certain model is 1, it indicates that the aging performance corresponding to this intelligent cat door in this model is qualified. On the contrary, when the comprehensive aging performance evaluation result of a certain intelligent cat door in a certain model is -1, it indicates that the aging performance corresponding to this intelligent cat door in this model is unqualified.

[0023] Preferably, the expression of the comprehensive aging performance evaluation model is: , where represents the comprehensive aging performance evaluation result corresponding to the h-th intelligent cat door in the g-th model, represents the comprehensive aging performance evaluation value corresponding to the h-th intelligent cat door in the g-th model, is the set threshold of the comprehensive aging performance evaluation value. g represents the number corresponding to each model, g is a positive integer, and h represents the number corresponding to each intelligent cat door, h is a positive integer.

Among them, and are the standard mechanical performance evaluation value and standard sensor performance evaluation value corresponding to the set intelligent cat door respectively, and and are the weight factors corresponding to the mechanical performance evaluation value of the set intelligent cat door and the weight factors corresponding to the sensor performance evaluation value respectively.

If the number of unqualified cat doors corresponding to a certain model of intelligent cat door is greater than or equal to the third warning unqualified cat door number, start the enterprise's highest-level emergency response procedure, establish a multi-department emergency handling team led by the enterprise's senior leadership, including production, quality control, R & D, and after-sales, issue an emergency notice warning to the whole company. The warning information includes the model and the number of unqualified cat doors, completely stop the production, sales and delivery of this model of intelligent cat door, seal and mark all inventory products, and the production department conduct a deep inspection and evaluation on the entire production chain.

[0028] Preferably, the production quality grades corresponding to the qualified intelligent cat doors in each model are evaluated as follows: The comprehensive aging performance evaluation values corresponding to the qualified intelligent cat doors in each model are compared with the comprehensive aging performance evaluation value ranges corresponding to the set production quality grades. If the comprehensive aging performance evaluation value corresponding to a qualified intelligent cat door in a certain model is within the comprehensive aging performance evaluation value range corresponding to a certain set production quality grade, the production quality grade in the database is recorded as the production quality grade corresponding to the qualified intelligent cat door in that model.

[0029] Preferably, the maintenance plans corresponding to the production lines of intelligent cat doors in each model are analyzed as follows: E1.

[0030] E2.

Obviously, the drawings in the following description are only some embodiments of the present invention. For those of ordinary skill in the art, other drawings can be obtained based on these drawings without creative efforts.

[0036] Figure 1 It is a schematic diagram of the connection of the system modules of the present invention. DETAILED DESCRIPTION OF THE INVENTION

[0037] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0038] As shown in the embodiments of the present invention Figure 1 An aging test system for electronic products includes: an initial test classification module, an aging performance analysis module, an intelligent cat door model evaluation module, a production quality grade evaluation module, and a database.

[0039] The aging performance analysis module is respectively connected to the initial test classification module and the intelligent cat door model evaluation module. The production quality grade evaluation module is respectively connected to the intelligent cat door model evaluation module. The database is respectively connected to the initial test classification module and the production quality grade evaluation module.

[0040] Initial test classification module: used to obtain the models corresponding to each intelligent cat door in the current batch of the target electronic product enterprise, and allocate each intelligent cat door to each initial test platform, so as to test the aging performance corresponding to each intelligent cat door in each model, and adjust the test settings for each model of intelligent cat door.

[0041] In a specific embodiment, the process of allocating each intelligent cat door to each initial test platform is as follows: A1. First, scan the barcodes of each intelligent cat door through a scanning device, and then obtain the models corresponding to each intelligent cat door through the barcodes of each intelligent cat door.

[0042] A2. Then, automatically allocate each intelligent cat door of the same model to the corresponding initial test platform through an automatic sorting device.

[0043] In another specific embodiment, the aging performance of each smart cat door in each model is tested, and the test settings of each model of smart cat door are adjusted. The specific adjustment process is as follows: B1. Obtain the number of mechanical failures, number of sensor failures, first mechanical failure usage time and first sensor failure usage time corresponding to the feedback of each user of each smart cat door in each model in the historical period, and add up the number of mechanical failures and number of sensor failures corresponding to the feedback of each user of each model of smart cat door to obtain the total number of mechanical failures and total number of sensor failures corresponding to each model of smart cat door. At the same time, the first mechanical failure usage time and the first sensor failure usage time corresponding to the feedback of each user of each model of smart cat door are added respectively, and then divided by the number of first sensor failure users who reported the first mechanical failure, so as to obtain the average first mechanical failure usage time and the average first sensor failure usage time corresponding to each model of smart cat door.

[0044] It should be noted that the first mechanical failure usage time refers to the time span from the time the user starts using a certain model of smart cat door to the time when the smart cat door first experiences a mechanical failure. The first sensor failure usage time refers to the time span from the start of use of the smart cat door to the first occurrence of a sensor-related failure.

[0045] It should also be noted that when the company's after-sales service team provides users with repair and maintenance services, it will keep detailed records of the fault conditions of the repaired smart cat door, including the type of fault, the time when the fault occurred, and other information. By sorting and compiling the after-sales service records, the number of mechanical failures and sensor failures of each model of smart cat door can be obtained. When users report mechanical failures or sensor failures through customer service channels, in addition to recording the type of failure, customer service personnel must also ask users about the time from the beginning of using the smart cat door to the first occurrence of the failure, so as to obtain specific data on the duration of use of the first mechanical failure and the duration of use of the first sensor failure.

[0046] B2. Compare the total number of mechanical failures, total number of sensor failures, average usage time for the first mechanical failure and average usage time for the first sensor failure corresponding to each model of smart cat door with the total number of mechanical failures interval, total number of sensor failures interval, average usage time for the first mechanical failure and average usage time for the first sensor failure corresponding to each test setting adjustment value in the database. If the total number of mechanical failures, total number of sensor failures, average usage time for the first mechanical failure and average usage time for the first sensor failure corresponding to a certain model of smart cat door are all within the total number of mechanical failures interval, total number of sensor failures interval, average usage time for the first mechanical failure and average usage time for the first sensor failure corresponding to a certain test setting adjustment value in the database, then use the test setting adjustment value in the database as the test setting adjustment value of the smart cat door of this model and make adjustments.

[0047] Aging performance analysis module: After the aging performance tests for each intelligent cat door corresponding to each model are completed, it is used to evaluate whether the aging performance of each intelligent cat door corresponding to each model is qualified, and mark each intelligent cat door with unqualified performance in each model as each unqualified intelligent cat door, and mark each intelligent cat door with qualified performance in each model as each qualified intelligent cat door.

[0048] In a specific embodiment, the initial test classification module further includes a performance index acquisition unit and a performance index analysis unit.

[0049] The performance index acquisition unit is used to set a number of acquisition time points during the aging performance tests for each intelligent cat door corresponding to each model, and then collect the mechanical performance indexes and sensor performance indexes corresponding to each intelligent cat door in each model at each acquisition time point. The mechanical performance indexes include the maximum opening and closing angle, the compression amount of the sealing strip, and the door gap. The sensor performance indexes include the induction distance, the response duration, and the detection angle.

[0050] It should be noted that for the aging test of mass-produced intelligent cat doors, an automated measurement system can be used. Install an optoelectronic sensor or a mechanical limit device on the test platform. When the door body is opened to the maximum position, the sensor or the limit device is triggered, and the system automatically records the angle data at this time, so as to obtain the maximum opening and closing angle. Install a displacement sensor near the sealing strip. When the door body is closed, the displacement sensor can monitor the deformation of the sealing strip in real time, so as to accurately obtain the compression amount data of the sealing strip. Use a laser rangefinder to measure the distances at different positions between the door frame and the door body when the door body is closed respectively, and obtain the accurate value of the door gap.

[0051] It also should be noted that use high-precision distance measurement equipment, such as a laser rangefinder or an infrared rangefinder, etc., to accurately measure the distance between the test object and the sensor. The automated test system controls the sending and receiving of signals through programming, and uses a timing module to accurately record the response duration. During the aging test process, multiple response duration tests are automatically carried out at set time intervals to monitor the change of the sensor response duration in real time. Fix the intelligent cat door on an angle rotation platform, and place a standard test object at a certain distance. Centering on the sensor, gradually rotate the angle rotation platform to change the angle between the test object and the sensor. When the sensor can just detect the test object, record the angle value at this time.

[0052] The performance index analysis unit is used to analyze and obtain the mechanical performance evaluation values and sensor performance evaluation values corresponding to each intelligent cat door in each model according to the mechanical performance indexes and sensor performance indexes corresponding to each intelligent cat door in each model at each acquisition time point.

[0053] In another specific embodiment, the mechanical performance evaluation values and sensor performance evaluation values corresponding to each intelligent cat door in each model are obtained through analysis. The specific analysis process is as follows: C1. Input the maximum opening and closing angle, compression amount of the sealing strip, and door gap corresponding to each intelligent cat door in each model at each acquisition time point into the mechanical performance evaluation analysis model, and output the mechanical performance evaluation values corresponding to each intelligent cat door in each model.

[0054] It should be noted that the analysis process of the mechanical performance evaluation values corresponding to each intelligent cat door in each model is as follows: Normalize the maximum opening and closing angle, compression amount of the sealing strip, and door gap corresponding to each intelligent cat door in each model at each acquisition time point, and denote the processed maximum opening and closing angle, compression amount of the sealing strip, and door gap corresponding to each intelligent cat door in each model at each acquisition time point as 、 and , substitute them into the analysis formula , and obtain the mechanical performance evaluation values corresponding to each intelligent cat door in each model. Here, y represents the number corresponding to each acquisition time point, y is a positive integer, g represents the number corresponding to each model, g is a positive integer, h represents the number corresponding to each intelligent cat door, h is a positive integer, 、 、 are respectively the weight coefficients corresponding to the maximum opening and closing angle of the intelligent cat door, the compression amount of the sealing strip, and the door gap.

[0055] It should be noted that according to the professional knowledge and research basis of domain experts, discussions and confirmations are carried out with industry organizations or professional institutions. The weight coefficients corresponding to the maximum opening and closing angle of the intelligent cat door, the compression amount of the sealing strip, and the door gap are set by experts based on their own experience and knowledge.

[0056] C2. Input the sensing distance, response duration, and detection angle corresponding to each intelligent cat door in each model at each acquisition time point into the sensor performance evaluation analysis model, and output the sensor performance evaluation values corresponding to each intelligent cat door in each model.

[0057] It should be noted that the analysis process of the sensor performance evaluation values corresponding to each intelligent cat door in each model is as follows: Normalize the sensing distance, response duration, and detection angle corresponding to each intelligent cat door in each model at each acquisition time point, and denote the processed sensing distance, response duration, and detection angle corresponding to each intelligent cat door in each model at each acquisition time point as 、 and , substitute them into the analysis formula , and obtain the sensor performance evaluation values , where y represents the number corresponding to each acquisition time point, y is a positive integer, g represents the number corresponding to each model, g is a positive integer, and h represents the number corresponding to each intelligent cat door, h is a positive integer. , , are respectively the weight coefficients corresponding to the set sensing distance of the intelligent cat door, the weight coefficients corresponding to the response duration, and the weight coefficients corresponding to the detection angle.

[0058] It should be noted that according to the professional knowledge and research basis of domain experts, discussions and confirmations are carried out with industry organizations or professional institutions. The experts set the weight coefficients corresponding to the sensing distance of the intelligent cat door, the weight coefficients corresponding to the response duration, and the weight coefficients corresponding to the detection angle according to their own experience and knowledge.

[0059] In another specific embodiment, to evaluate whether the aging performance corresponding to each intelligent cat door in each model is qualified, the specific evaluation process is as follows: input the mechanical performance evaluation value and the sensor performance evaluation value corresponding to each intelligent cat door in each model into the comprehensive aging performance evaluation model, and output the comprehensive aging performance evaluation results of each intelligent cat door in each model.

[0060] The comprehensive aging performance evaluation results of the intelligent cat door include values of 1 and -1. When the comprehensive aging performance evaluation result of a certain intelligent cat door in a certain model is 1, it indicates that the aging performance corresponding to this intelligent cat door in this model is qualified; conversely, when the comprehensive aging performance evaluation result of a certain intelligent cat door in a certain model is -1, it indicates that the aging performance corresponding to this intelligent cat door in this model is unqualified.

[0061] In another specific embodiment, the expression of the comprehensive aging performance evaluation model is: , where represents the comprehensive aging performance evaluation result corresponding to the h-th intelligent cat door in the g-th model, represents the comprehensive aging performance evaluation value corresponding to the h-th intelligent cat door in the g-th model, is the set threshold of the comprehensive aging performance evaluation value, g represents the number corresponding to each model, g is a positive integer, and h represents the number corresponding to each intelligent cat door, h is a positive integer.

[0062] Record the mechanical performance evaluation value and the sensor performance evaluation value corresponding to each intelligent cat door in each model as and respectively, and substitute them into the calculation formula to obtain the comprehensive aging performance evaluation value corresponding to the h-th intelligent cat door in the g-th model, where , are respectively the set standard mechanical performance evaluation value and the standard sensor performance evaluation value corresponding to the intelligent cat door, , They are respectively the weight factors corresponding to the set mechanical performance evaluation values of the intelligent cat door and the weight factors corresponding to the sensor performance evaluation values.

[0063] It should be noted that , Both are greater than 0 and less than 1.

[0064] It should also be noted that through the summary of a large amount of research data and experimental data. According to the standard mechanical performance evaluation values and standard sensor performance evaluation values corresponding to the intelligent cat door set by professional institutions and research institutions, at the same time, based on the professional knowledge and research basis of domain experts, and through discussion and confirmation with industry organizations or professional institutions. The weight factors corresponding to the mechanical performance evaluation values of the intelligent cat door and the weight factors corresponding to the sensor performance evaluation values are set by experts according to their own experience and knowledge.

[0065] In the embodiments of the present invention, by comprehensively and meticulously testing the aging performance of various models of intelligent cat doors, including collecting and analyzing mechanical performance indicators such as the maximum opening and closing angle, the compression amount of the sealing strip, and the door gap, as well as sensor performance indicators such as the sensing distance, response duration, and detection angle, etc., it is possible to accurately evaluate the performance of the product in different aspects, timely discover potential quality problems, so as to ensure that only qualified products enter the market, effectively improve the overall quality of the product, enhance the reliability and stability of the product, and improve user satisfaction. Adjust the test settings of various models of intelligent cat doors according to the user feedback data in the historical cycle, making the test closer to the actual use situation and the weak links of the product, which can more accurately detect the possible problems of the product, further ensure the product quality, and help the enterprise continuously optimize the product design and production process, and improve the product quality from the source.

[0066] Intelligent cat door model evaluation module: used to count the number of unqualified intelligent cat doors corresponding to each model, so as to analyze the production warning plan corresponding to each model of intelligent cat door.
