Description

Technical Field

[0001] The present application relates to the field of electrical appliance testing technology, and specifically to an automated performance testing method, testing device and system for a membrane switch. Background Art

[0002] Membrane switch is a human-machine interface element widely used in various electronic devices, usually used to control devices such as buttons, display screens and keyboards. It has the characteristics of simple structure, waterproof and dustproof, durable and thin. The main working principle of membrane switch is to trigger the key and transmit the signal through the interaction between the conductive layer and the insulating layer in its structure, that is, when the key is pressed, the circuit is closed; when the key is released, the circuit is disconnected. Since the membrane switch needs to achieve specific electrical performance, sensitivity and feedback capabilities to be used normally, it is particularly important to perform automated testing on the membrane switch to obtain service life and working stability. In the prior art, the performance test method of the membrane switch is to press the finished membrane switch through automated equipment, and use sensors to automatically record the electrical parameters, response time, etc. from the beginning to the end of pressing, so as to analyze the actual working performance of the membrane switch. However, the pressing angle and pressing mode of the automated equipment are different from the habits of real operators. For example, when the fingers or pressing device are covered on the switch surface, the pressing device can only exert force evenly in one direction, while the human hand can apply force differently in each pressing process due to the different pressing angles and pressing positions of the fingers, which leads to lower authenticity of the detection results of the automated equipment.

DETAILED DESCRIPTION

[0032] In order to solve the technical problem that the existing detection method proposed in the background technology makes the detection result of the membrane switch less authentic, the present application proposes an automatic performance detection method of the membrane switch, such as Figure 1 As shown, the automatic performance detection method of the membrane switch includes steps S100 to S500.

[0033] Step S100: forming a usage database based on multiple usage parameters of the membrane switch.

[0034] In this embodiment, various usage parameters are acquired in advance, and each usage parameter includes at least the pressing force, pressing angle, pressing time, gender, age, and working time of the operator when the membrane switch is used. It should be noted that before forming a usage database, the specific usage scenario of the membrane switch needs to be determined. Because the user groups and usage environments of the membrane switch are different in different usage scenarios, different usage scenarios will affect the parameter settings for the automatic detection of the membrane switch. In the embodiments below, the membrane switch test in the usage scenario of the factory assembly line is taken as an example to illustrate the automatic performance detection method of the membrane switch proposed in this application. It does not mean that the automatic performance detection method of the membrane switch proposed in this application is only applicable to the membrane switch test in the factory assembly line. It should be understood that the automatic performance detection method of the membrane switch proposed in this application is applicable to the membrane switch test in any usage scenario.

[0035] In this embodiment, the relevant information of the membrane switch operator can be obtained through questionnaires, public databases, etc., for example, the relevant information of the workers on a factory assembly line can be obtained. It should be noted that the relevant information of the operator includes physical information (age, gender, etc.), work environment information (temperature and humidity, etc.), and work information (work intensity, work hours, etc.). Furthermore, the pressing force and pressing time of the workers on the assembly line when pressing the membrane switch are collected through sensors (pressure sensors and timers, etc.), thereby forming a usage database.

[0036] Step S200: Based on the usage database, a first pressure parameter range is obtained.

[0037] It should be clear that the first pressure parameter range includes the first minimum pressing force and the first maximum pressing force when the membrane switch is tested. That is to say, in this embodiment, the range between the first minimum pressing force and the first maximum pressing force is the first pressure parameter range. Each membrane switch has a minimum trigger pressure, so the first minimum pressing force can be the minimum trigger pressure of the membrane switch. The first maximum pressing force can be the maximum pressing force in the database. If the first maximum pressing force is the maximum pressing force in the database, the authenticity of the test parameters randomly generated in step S300 is poor. If the authenticity of the test parameters is poor, the authenticity of the membrane switch detection results is still low. In order to obtain test parameters with higher authenticity, in one embodiment of the present application, step S200, based on the usage database, obtains the first pressure parameter range, including steps S210 to S250.

[0038] Step S210: Based on the usage database, a clustering algorithm is used to obtain a plurality of clusters.

[0039] It should be clear that in the factory assembly line, since the pressure applied by male and female operators to the membrane switch is different, the pressure applied by males is generally greater, while the pressure applied by females is smaller. Operators of different age groups also apply different pressures to the membrane switch. Generally, young and middle-aged people apply greater pressures, while middle-aged and elderly people apply less pressure. If the maximum pressure applied in the database is used as the upper limit of the first pressure parameter range, the authenticity of the test parameters subsequently obtained is poor. Based on this, in this embodiment, clustering is performed for each usage parameter in the usage database. In this embodiment, the age span of each clustering cluster is 5 years old, and the gender of the operator in each usage parameter in the same clustering cluster is the same. Of course, in other embodiments, the age span of each clustering cluster can be other age values, for example, 2 years old or 3 years old.

[0040] Step S220: Based on each cluster, obtain the standard pressing force corresponding to each cluster.

[0041] In the embodiment of the present application, the standard pressing force is at least used to characterize the average pressing force of each operator in each cluster. That is, in this embodiment, the average pressing force in each cluster can be used as the standard pressing force corresponding to each cluster.

[0042] It should be noted that the older the operator is, the smaller the pressure applied by the operator. For the same operator, as the working time increases, his fatigue increases, and the pressure applied to the membrane switch becomes smaller. In order to further improve the authenticity of the test parameters obtained subsequently, in one embodiment of the present application, step S220, based on each cluster, obtains the standard pressure corresponding to each cluster, including steps S221 to S224.

[0043] Step S221: Based on each cluster, obtain a first cluster.

[0044] In this embodiment, the first cluster is any cluster among the clusters. That is to say, in this application, the standard pressing force corresponding to each cluster can be obtained by referring to the method for obtaining the standard pressing force of the first cluster.

[0045] Step S222: Based on the first cluster, obtain a first usage parameter.

[0046] In this embodiment, the first usage parameter is any usage parameter except the usage parameters with the maximum and minimum pressing force in the first cluster. That is, in this embodiment, the usage parameters with the maximum and minimum pressing force in the first cluster are removed to reduce data collection errors.

[0047] Step S223: Based on the first usage parameter, obtain a corresponding penalty coefficient.

[0048] In this embodiment, the penalty coefficient at least represents the size of the product of the age value and the working time value corresponding to the first usage parameter. In this embodiment, the penalty coefficient can be directly the product of the age value and the working time value corresponding to the first usage parameter. In order to facilitate the adjustment of the standard pressing force by the penalty coefficient in the subsequent process, in one embodiment of the present application, step S223, based on the first usage parameter, the calculation formula for obtaining the corresponding penalty coefficient can be as follows: in, Represents the penalty coefficient corresponding to the jth usage parameter in the i-th cluster; represents the value of the working time in the jth usage parameter in the i-th cluster, where Greater than 0; represents the value of the operator's age in the jth usage parameter in the i-th cluster; It indicates that the normalization function is used to map the value in the brackets to the interval range of [-0.5, 0.5]. That is to say, in this embodiment, if an operator is older or has worked longer, the corresponding penalty coefficient will be larger.

[0049] Step S224: based on the first usage parameter and the corresponding penalty coefficient, obtaining the standard pressing force corresponding to the first cluster.

[0050] In this embodiment, any reasonable method may be used to obtain the standard pressing force corresponding to the first cluster based on the first usage parameter and the corresponding penalty coefficient. For example, in step S224, the calculation formula for obtaining the standard pressing force corresponding to the first cluster based on the first usage parameter and the corresponding penalty coefficient may be as follows: in, represents the standard pressing force corresponding to the i-th cluster; represents the number of parameters used in the i-th cluster, where is a positive integer greater than 2; Represents the penalty coefficient corresponding to the jth usage parameter in the i-th cluster; Represents the pressing force in the jth usage parameter in the ith cluster. In this embodiment, the standard pressing force is adjusted by the penalty coefficient so that the standard pressing force approaches the pressing force of a normal user at this age. It is easy to understand that in this embodiment, if the operator is older and has a longer working time, the pressing force applied to the membrane switch is increased accordingly by the penalty coefficient. If the operator is younger and has a shorter working time, the pressing force applied to the membrane switch is decreased accordingly by the penalty coefficient so that the obtained standard pressing force approaches the pressing force of a normal user at this age.

[0051] Step S230: Obtain the gender ratio of operators in the usage database.

[0052] As can be seen from the above, the pressing force of the membrane switch by male and female operators is also different. It is easy to understand that if the membrane switch operators are mostly female, the pressing force of the membrane switch is generally smaller when used, and if the membrane switch operators are mostly male, the pressing force of the membrane switch is generally larger when used. In other words, the maximum pressing force of the membrane switch when used is closely related to the gender ratio of the operators.

[0053] Step S240: obtaining a first maximum pressing force based on the male-female ratio and the standard pressing force corresponding to each cluster.

[0054] In this embodiment, the first maximum pressing force can be obtained based on the male-female ratio and the standard pressing force corresponding to each cluster in any reasonable manner. For example, in step S240, the calculation formula for obtaining the first maximum pressing force based on the male-female ratio and the standard pressing force corresponding to each cluster can be as follows: in, Indicates the first maximum pressing force; indicates the proportion of males using the operators in the database; Represents the average value of the standard pressing force corresponding to each male cluster; indicates the proportion of women using the operators in the database; Represents the average value of the standard pressing force corresponding to each female cluster.

[0055] Step S250: acquiring a first pressure parameter range based on the first maximum pressing force.

[0056] As can be seen from the foregoing, in this embodiment, the lower limit of the first pressure parameter range is the minimum triggering pressure of the membrane switch, and the upper limit of the first pressure parameter range is the first maximum pressing force.

[0057] Step S300: Generate test parameters based on the first pressure parameter range.

[0058] In an embodiment of the present application, the test parameters at least include the pressing force, pressing angle and pressing duration during the membrane switch test. It should be noted that the pressing force, pressing angle and pressing duration during the membrane switch test in the test parameters can be randomly generated. For example: the pressing force during the membrane switch test can be randomly generated within the first pressure parameter range, and the pressing angle and pressing duration during the membrane switch test can also be randomly generated. In this embodiment, the pressing angle during the test can be greater than or equal to the smallest pressing angle in the usage database, and less than or equal to the largest pressing angle in the usage database. The test pressing duration can be greater than or equal to the smallest pressing duration in the usage database, and less than or equal to the largest pressing duration in the usage database. It should be clear that randomly generating a certain value from a certain range of values ​​is a mature technology and will not be elaborated here.

[0059] It should be noted that in the detection process, in order to improve the coverage of the test results, the detection is carried out by randomly generating test parameters, so as to simulate the randomness of the operator's pressing in the real use scenario and improve the authenticity of the detection results. The pressing angle has an impact on the pressing force. It should be clear that the minimum triggering pressure of the membrane switch refers to the minimum force that can successfully press the membrane switch in the direction perpendicular to the membrane switch. As can be seen from the foregoing, different users have different usage habits. If the applied force is not in the vertical direction and the magnitude of the applied force is equal to the minimum triggering pressure of the membrane switch, it is likely that the membrane switch will not be successfully pressed. In other words, if the randomly generated test parameter pressing angle is not perpendicular to the membrane switch, and the pressing force is close to the minimum triggering pressure of the membrane switch, the membrane switch may not be successfully pressed according to the test parameters. If the membrane switch cannot be successfully pressed, the test process is invalid, that is, the authenticity of the test results is poor.

[0060] In order to ensure that each test parameter can successfully press the membrane switch to improve the authenticity of the test result, in one embodiment of the present application, step S300 generates a test parameter based on the first pressure parameter range, including steps S310 to S350.

[0061] Step S310: Randomly generate a test angle and a test duration based on the usage database.

[0062] In this embodiment, the test angle is the pressing angle during the test, and the test duration is the pressing duration during the test. The test angle is greater than or equal to the smallest pressing angle in the usage database, and less than or equal to the largest pressing angle in the usage database. The test duration is greater than or equal to the smallest pressing duration in the usage database, and less than or equal to the largest pressing duration in the usage database.

[0063] Step S320: Based on the test angle, obtain the contact area during the test.

[0064] It is easy to understand that, in general, the more vertical the direction in which the finger presses the membrane switch, the larger the contact area between the finger and the membrane switch, and the smaller the pressing force required to successfully press the membrane switch. In other words, the larger the deviation between the pressing angle and the direction perpendicular to the membrane switch, the smaller the contact area between the finger and the membrane switch, that is, the greater the pressing force required to successfully press the membrane switch. Based on this, in step S320, based on the test angle, the calculation formula for obtaining the contact area during the test can be as follows: in, Indicates the contact area during the test corresponding to the xth test parameter; Indicates the maximum contact area of ​​the membrane switch; It indicates the angle between the direction of the test angle in the xth test parameter and the direction of vertically pressing the membrane switch. It is easy to understand that in this embodiment, the larger the angle between the direction of the test angle and the direction of vertically pressing the membrane switch, that is, the greater the difference between the two pressing directions, the smaller the contact area during the test.

[0065] Step S330: Based on the contact area and the first pressure parameter range, a second pressure parameter range during testing is obtained.

[0066] In this embodiment, the second pressure parameter range during the test is obtained in order to subsequently randomly generate the test pressure in the test parameter from the second pressure parameter range. It is easy to understand that the more accurate the second pressure parameter range is, the more reasonable the test pressure obtained is. That is to say, in this embodiment, the second pressure parameter range includes the second minimum pressing force and the second maximum pressing force during the membrane switch test; the second minimum pressing force is greater than or equal to the first minimum pressing force; the second maximum pressing force is less than or equal to the first maximum pressing force.

[0067] As can be seen from the foregoing, the second minimum pressing force is positively correlated with the contact area during the test. If the contact area is smaller, the second minimum pressing force is larger; if the contact area is larger, the second minimum pressing force is smaller. In other words, in this embodiment, as long as the above rules are met, any reasonable method can be used to obtain the second pressure parameter range during the test based on the contact area and the first pressure parameter range. For example, in a specific embodiment of the present application, step S330, based on the contact area and the first pressure parameter range, obtains the second pressure parameter range during the test, including steps S331 to S333.

[0068] Step S331: Based on the first pressure parameter range, taking the first maximum pressing force as the second maximum pressing force.

[0069] In this embodiment, the upper limit of the second pressure parameter range is the second maximum pressing force.

[0070] Step S332: Based on the contact area and the first minimum pressing force, obtain the second minimum pressing force.

[0071] As can be seen from the foregoing, since the second minimum pressing force is related to the contact area during the test, the calculation formula for the second minimum pressing force can be as follows: in, Indicates the second minimum pressing force corresponding to the xth test parameter; Indicates the minimum triggering pressure of the membrane switch; Indicates the contact area during the test corresponding to the xth test parameter; Indicates the maximum contact area of ​​the membrane switch.

[0072] Step S333: Based on the second minimum pressing force and the second maximum pressing force, obtain a second pressure parameter range during the test.

[0073] As can be seen from the foregoing, the upper limit of the second pressure parameter range is the second maximum pressing force, and the lower limit is the second minimum pressing force. If the second minimum pressing force and the second maximum pressing force are obtained, the second pressure parameter range is obtained.

[0074] Step S340: randomly generating a test pressure based on the second pressure parameter range.

[0075] In this embodiment, the test pressure is the pressing force during the test, and the test pressure is within the second pressure parameter range. In this embodiment, the pressing force generated based on the second pressure parameter range takes into account the pressing direction. Compared with the pressing force generated without considering the pressing direction, the pressing force randomly generated in this embodiment is more authentic. That is, the authenticity of the test results obtained subsequently is also higher.

[0076] Step S350: Generate a first test parameter based on the test angle, the test pressure and the test duration.

[0077] In this embodiment, the first test parameter is composed of a test angle, a test pressure and a test duration.

[0078] It should be clear that since the operator's pressing force when pressing the membrane switch cannot be as stable as a machine, that is, maintaining a stable pressing force, the pressing force fluctuates during the pressing process, so it is necessary to dynamically simulate the pressing force to further improve the authenticity of the detection result. Based on this, in one embodiment of the present application, in step S350, after generating the first test parameter based on the test angle, the test pressure and the test duration, the method also includes steps S360 to S380.

[0079] Step S360: Adjust the test angle and obtain the adjusted angle.

[0080] It should be clear that in the long-term working process, the pressure force of the operator on the membrane switch fluctuates greatly, while the fluctuation of the pressing angle is generally small. That is to say, in this embodiment, the test angle can be fine-tuned based on the test angle in the first test parameter. For example, the adjustment angle can be the test angle , or test angle wait.

[0081] Step S370: Based on the adjustment angle, obtain the adjusted contact area.

[0082] In this embodiment, based on the adjustment angle, the adjusted contact area is obtained, and the steps are the same as step S320, which will not be described in detail here.

[0083] Step S380: Generate a second test parameter based on the adjustment angle and the adjusted contact area.

[0084] In this embodiment, the step of generating the second test parameter based on the adjusted contact area refers to step S330 to step S350, which will not be described in detail here.

[0085] Step S400: Based on the test parameters, the membrane switch is tested to obtain a test result.

[0086] It should be noted that testing the membrane switch based on various test parameters (including the first test parameter and the second test parameter mentioned above) is a mature technology and will not be described in detail here. In this embodiment, the test results include electrical parameters (such as resistance and voltage, etc.), mechanical performance parameters (such as pressing stroke change and switch rebound speed, etc.) and working performance parameters (such as response delay and life, etc.) of the membrane switch.

[0087] Step S500: Generate a performance index based on the test results.

[0088] In this embodiment, the performance index is at least used to characterize the quality of the test performance of the membrane switch. In the embodiment of the present application, the performance index can be generated based on the test results in any reasonable manner. For example, by performing automated performance tests on a batch of membrane switches for their application scenarios, a large number of test result samples are obtained. Based on these test result samples, the step of generating the performance index includes steps S510 to S540.

[0089] Step S510: pre-process each test result sample (data cleaning, etc.).

[0090] It should be clear that data cleaning is a mature technology and will not be discussed in detail here.

[0091] Step S520: according to the requirements of the membrane switch usage scenario, corresponding weights are set for data of different dimensions.

[0092] It should be clear that, based on the requirements of the usage scenario, setting corresponding weights for data of different dimensions is a mature technology and will not be elaborated here.

[0093] Step S530: for the preprocessed test result samples, respectively calculate the data means of different data dimensions.

[0094] It should be clear that calculating the average of multiple data values ​​is a mature technology and will not be described in detail here.

[0095] Step S540: Generate a performance index based on the data means of different data dimensions and the weights of the data of different dimensions. The calculation formula for generating the performance index is as follows: in, represents the performance index corresponding to the membrane switch; m represents the number of data of different dimensions; Represents the weight corresponding to the v-th dimension data; Represents the data mean corresponding to the v-th dimension data; Represents the normalization function, which is used to The value of is normalized to [0, 1] and the dimension is removed.

[0096] In this embodiment, the quality of the membrane switch is directly judged based on the performance index. For example, a threshold value can be set. If the performance index is less than a preset value, it can be considered that the current batch of membrane switches does not meet the usage requirements of the scene; if the performance index is greater than or equal to the preset value, it can be considered that the current batch of membrane switches meets the usage requirements of the scene.
