An embodiment of the present invention provides a method for determining a product status, and referring to fig. 2, fig. 2 is a schematic flowchart of a first embodiment of a method for determining a product status according to the present invention. It should be noted that, although a logical order is shown in the flow chart, in some cases, the steps shown or described may be performed in an order different than that shown or described herein. The executed product determination method may be a device such as a personal computer, a smart phone, a server, etc., and is not limited in this embodiment, and for convenience of description, the following description of the executed subject is omitted. In this embodiment, the product state determination method includes:

step A10, acquiring first test information obtained by performing reliability test on a first to-be-detected product in a failure undetected state;

the reliability test is a test performed after production in order to evaluate the service life of a product. The reliability test is a continuous cyclic process, i.e., multiple rounds of testing of the product are required. During a reliability test, when a product has an abnormal condition in a round of test, the product can be marked as a failure undetected state; on a test line, the reliability test of the current round is not carried out on the product marked as the undetected state of failure, but after the engineer carries out failure analysis on the product marked as the undetected state of failure, the reason of the abnormal condition of the product is determined according to the result of the failure analysis or whether the abnormal condition of the product affects the actual use of the user is determined; if the use of the product is influenced, the reliability test of the product is ended, namely, the next round of test is not started; if the actual use of the user is not influenced, namely the reliability test is not influenced by the abnormal condition of the product, the product in the failure undetected state can be put into the next round of test.

When a product in a state of failure undetected is put into a next round of test, if the product has an abnormal condition in a new round of test, an engineer is required to perform failure analysis on the product again, if the abnormal condition of the product in the new round of test is the same as that in the previous round of test, the engineer is caused to perform repeated failure analysis, and in order to avoid unnecessary repeated analysis by the engineer, the product in the state of failure undetected can be marked as the state of failure found when the same abnormal condition occurs in the new round of test. In the test, when the same abnormal condition occurs again in the product marked as the failure found state, the test is not suspended for the engineer to analyze the reason, so that the test time is saved until a new abnormal condition occurs. However, at present, the judgment of the failure found state of the product needs manual operation, so that the judgment efficiency is low, and the judgment result accuracy is low.

In the embodiment, in order to solve the problems of low efficiency and low accuracy of the determination result in the determination of the detected failure state of the product in the reliability test process, a product state determination method is provided, and the determination efficiency and the determination result accuracy can be improved by automatically determining the detected failure state of the product.

Specifically, in the present embodiment, a product to be subjected to a reliability test is referred to as a product to be inspected, and a determination process of a failure found state of one product to be inspected is described below as an example, and the product to be inspected is referred to as a first product to be inspected to be distinguished from other products to be inspected.

Test information (hereinafter referred to as first test information for distinction) during a reliability test of the first product to be tested in a failure undetermined state can be acquired. In the reliability test, the test information of the product to be tested can be obtained from the test station. The test information includes information that can embody a test result of the product or various normal or abnormal conditions in the test, and the content included in the test information is different according to the type of the product or the test requirement, that is, what information can be specifically included is not limited in this embodiment. In one embodiment, the test information may include a plurality of test values reflecting different test results or different abnormal conditions of the product. The test value may be recorded in a table form or a document form, and is not limited in this embodiment.

In a specific embodiment, a product to be tested in a failure undetermined state can be marked correspondingly, whether the first product to be tested is in the failure undetermined state can be seen according to whether the first product to be tested carries the mark in the failure undetermined state, and if the first product to be tested is determined to be in the failure undetermined state, test information of the first product to be tested, namely the first test information, can be acquired from a test station.

A step a20 of comparing the first test information with target rule information determined based on second test information for determining that the product is in a failure-undetermined state obtained in a reliability test of the product;

after the first test information is obtained, the first test information may be compared with the target rule information. The rule information is information for determining whether the test information of the product to be detected is consistent with the test information when the product to be detected enters the failure undetermined state before the test information, and the rule information for determining whether the first test information is consistent with the test information when the product to be detected enters the failure undetermined state before the test information is referred to as target rule information. The target rule information may be determined based on test information (hereinafter referred to as second test information) obtained by a product to be inspected in a reliability test for determining that the product to be inspected is in a failure-undetermined state.

If a product to be detected is detected with test information in the reliability test, the product to be detected is judged to be in a failure undetected state according to the test information, and when the failure undetected state of the product to be detected is determined not to influence the reliability test, namely the reason that the product to be detected is in the failure undetected state or the use of a user is not influenced, the test information of the product to be detected can be used as second test information. When the test information obtained by performing the reliability test on the same product to be tested or other products to be tested is consistent with the second test information of the product to be tested, the same product to be tested or other products to be tested which are to be tested and the product to be tested can be determined to be in the same failure undetected state. Then, a target rule information can be determined according to the second test information of the product to be tested, so that when the test information obtained by the subsequent test aiming at the same product to be tested or other products to be tested is consistent with the target rule information in comparison, the same product to be tested or other products to be tested which are tested can be considered to show the same failure undetected state as that in the previous test.

The specific manner of determining the target rule information according to the second test information is not limited in this embodiment, that is, as long as the target rule information can be used to determine that the state of the product to be tested is consistent with the failure undetected state represented by the second test information. In a specific embodiment, determining the target rule information based on the second test information may be directly using the second test information as the target rule information, that is, the target rule information is completely consistent with the second test information, or may be analyzing the second test information, and determining the target rule information according to an error allowable range of the test value. For example, in one embodiment, the test value of the second test information may be analyzed to determine an error allowable range of the test value, determine a test value range according to the error allowable range of the test value, and use the test value range as the target rule information. For example, when the test value in the second test information obtained by performing the temperature test on one product to be inspected is 80 ℃, the temperature value is subjected to error analysis, and if it is determined that the temperature is floating within the range of 70 ℃ to 90 ℃, it can be considered that the product to be inspected is still in the same undetected state of failure, and one temperature range can be determined as the target rule information according to 70 ℃ to 90 ℃.

The second test information may be test information obtained by the first product to be tested in the failure undetected state before the current round of reliability test, or may be test information of other products to be tested in the reliability test that is determined as the failure undetected state and the abnormal condition does not affect the reliability test, which is not limited in this embodiment.

Specifically, in this embodiment, the acquired first test information of the first to-be-detected product is compared with the target rule information based on the second test information, and when the first test information is consistent with the target rule information, it may be determined that the state of the first to-be-detected product is the same as the non-ascertained state of failure in the previous test. When the first test information is inconsistent with the target rule information, it may be determined that the state of the first product to be tested is different from the failure undetected state in the previous test.

Step a30, when the first test information is consistent with the target rule information, determining the status of the first product to be tested as a failure ascertained status.

In the reliability test, when the product to be detected in the non-detection failure state is in the same abnormal condition in the new reliability test, the state of the product to be detected can be determined to be consistent with the non-detection failure state in the previous test, at the moment, the state of the product to be detected is determined to be the non-detection failure state, the reliability test is continued on the product to be detected in the non-detection failure state, and the failure analysis is not carried out on the product to be detected in the test period until the new abnormal condition occurs on the product to be detected.

In this embodiment, by comparing the first test information with the target rule information determined based on the second test information for determining that the product to be inspected is in the failure undetermined state, when the first test information coincides with the target rule information, it can be determined that the state of the first product to be inspected is the same as the failure undetermined state in the previous test, that is, it can be determined that the first product to be inspected is in the failure found state in the current reliability test.

Further, in an embodiment, after the first to-be-detected product is determined to be in the failure ascertained state, the first to-be-detected product in the failure ascertained state may be further marked.

Compared with the manual judgment of the undetected state of the product, the judgment speed of the judgment by using an automatic method is higher, the working efficiency is higher, and the judgment result is more accurate.

Further, in one embodiment, step a10 includes:

a101, acquiring third test information obtained by performing reliability test on a first product to be tested;

in this embodiment, after the state of the product to be tested is determined, a marking can be made in the test information of the product to be tested, which marking is used to indicate that the product to be tested is in a failure undetermined state or a failure detected state during the reliability test. The test information obtained by performing reliability test on the product to be tested may or may not include a mark of the product state. If the product to be tested is determined to be in a failure undetermined state in a previous reliability test, the test information comprises an mark of the failure undetermined state; if the product to be tested is not in a failure undetermined state in a previous reliability test or if the product to be tested has not been subjected to the reliability test previously, the test information does not include a mark.

In this embodiment, the first product to be tested may not be marked before the current round of reliability test is performed, or may already be marked as a non-failure-found state, and the reliability test is performed on the first product to be tested to obtain test information (hereinafter referred to as third test information), where the third test information may not include the non-failure-found mark, or may include the non-failure-found state mark, and it may be determined whether the first product to be tested is in the non-failure-found state or not in the reliability test according to the third test information.

Step a102, when it is determined that the third test information includes the flag of the failure undetermined state, the third test information is taken as the first test information.

When the third test information includes an indication of a failure unacknowledged state, it can be determined that the first product to be tested has been determined to be a failure unacknowledged state before the current round of reliability test.

In the present embodiment, when it is determined that the third test information already contains the mark of the failure undetected state, the third test information is used as the first test information for determining whether the failure undetected state of the first product to be tested in the current round of reliability test is the same as the failure undetected state in the previous test.

Further, in one embodiment, step a20 includes:

step A201, when the type of the test value in the first test information is character type, performing character string matching on the test value and the target value in the target rule information, and when the test value is consistent with the target value, determining that the first test information is consistent with the target rule information;

the test information may include a plurality of test values, and the test values may reflect different test results or different abnormal conditions of the product to be tested, where the type of the test value may be a character type, a numerical type, or a symbol mark, and the type of the test value is not limited in the specific implementation manner. The target rule information determined based on the second test information may also include a plurality of test values (hereinafter referred to as target values for distinction), and similarly, the type of the target value may be a character type, a numerical type, or a symbol mark, and the type of the target value is not limited in the specific embodiment.

In one embodiment, the test value in the first test information may be a character type, where the character type test value is a character string, and the first test information is compared with the target rule information, that is, the test value of the character type in the first test information is character string matched with the target value of the character type in the target rule information. When the character string matching of the test value and the target value is consistent, the test value and the target value can be determined to be consistent, namely the first test information and the target rule information can be determined to be consistent, namely the failure undetected state of the first to-be-detected product in the current reliability test can be determined to be the same as the failure undetected state in the previous test; when the character string matching of the test value and the character string matching of the target value are inconsistent, the test value and the target value can be determined to be inconsistent, namely the first test information and the target rule information can be determined to be inconsistent, namely the failure unacknowledged state of the first to-be-detected product in the current round of reliability test is determined to be different from the failure unacknowledged state in the previous round of reliability test.

Step A202, when the type of the test value in the first test information is numerical, comparing the test value with a target numerical range in the target rule information, and when the test value is within the target numerical range, determining that the first test information is consistent with the target rule information.

In one embodiment, the test value in the first test information may be a numerical value, wherein the numerical test value is a specific numerical value, and the first test information is compared with the target rule information, that is, the test value of the numerical value in the first test information is compared with a target numerical value range in the target rule information, wherein the numerical value range is determined based on the test value of the second test information of the product to be inspected in the failure non-ascertained state. When the test value of the first test information does not exceed the target value range in the target rule information, the first test information can be determined to be consistent with the target rule information, namely the failure undetected state of the first product to be detected in the current reliability test can be determined to be the same as the failure undetected state in the previous test; when the test value of the first test information exceeds the target value range in the target rule information, it may be determined that the first test information is inconsistent with the target rule information, that is, it may be determined that the failure undetected state of the first product to be tested in the current round of reliability test is different from the failure undetected state in the previous test.

In this embodiment, first test information obtained by performing a reliability test on a first to-be-detected product in a non-ascertained failure state is acquired, and the first test information is compared with target rule information, where the target rule information is determined based on second test information obtained in the reliability test of the product and used for determining that the product is in the non-ascertained failure state, and when the first test information is consistent with the target rule information, the state of the to-be-detected product is determined to be the ascertained failure state. According to the embodiment, the method and the device, the failure found state of the product is judged by using an automatic method in the reliability test process, and the judgment efficiency and the judgment result accuracy are improved.

Further, based on the first embodiment, a second embodiment of the product status determination method according to the present invention is provided, and in this embodiment, before step a20, the method further includes:

step A40, determining whether a preset abnormal condition occurs in the product to be detected according to abnormal value information obtained by reliability test of the first product to be detected;

in the reliability test, the abnormal condition of the product to be detected may exceed the expected abnormal condition, namely the preset abnormal condition, and whether the abnormal condition of the product to be detected is the preset abnormal condition can be determined according to the abnormal value information obtained by the reliability test of the product to be detected. The preset abnormal condition is usually a problem caused by an improper production process, for example, the charging type product cannot be charged, for example, the serial number of the product cannot be read, and when the preset abnormal condition occurs, the reliability test is no longer performed on the product to be detected. And the abnormal condition that the product is in the failure undetermined state is a condition that occurs in the reliability test and is irrelevant to the production process.

Specifically, in the present embodiment, the abnormal value information of the first product to be detected is compared with the preset abnormal value information. When the abnormal value information is consistent with the preset abnormal value information, the first product to be detected can be determined to have a preset abnormal condition, and the reliability test of the first product to be detected is not performed any more; when the abnormal value information is inconsistent with the preset abnormal value information, it can be determined that the first product to be detected has no abnormal condition exceeding the expectation, and the reliability test can be continuously carried out on the first product to be detected.

Step a50, when the first product to be detected has no abnormal condition, executing the step of comparing the first test information with the target rule information.

When the first to-be-detected product is determined not to have the preset abnormal condition according to the abnormal value information of the first to-be-detected product, the first to-be-detected product can continue to carry out the reliability test, namely, the first to-be-detected product continues to be judged to be in a failure undetected state, namely, the step of comparing the first test information with the target rule information is carried out.

It should be noted that whether the preset abnormal condition occurs in the to-be-detected product is determined according to the abnormal value information of the first to-be-detected product, so that the product which has a problem in the production process is screened and eliminated before the state of the first to-be-detected product is judged, the judgment workload is reduced, the working efficiency is improved, and the accuracy of the judgment result is improved.

Further, based on the first embodiment, a third embodiment of the product status determination method according to the present invention is provided, where in this embodiment, before step a20, the method further includes:

step A60, obtaining a target production batch of a first product to be detected, and obtaining first rule information corresponding to the target production batch as target rule information from preset first rule information corresponding to various production batches, wherein the first rule information is determined based on second test information which is obtained by the products of the corresponding production batch in a reliability test and is used for judging that the products are in a failure undetected state;

in the reliability test, different test rounds can comprise different test conditions, different test stations can perform different function tests in the same test round, and products to be tested for the reliability test can be products from different production batches. On the test line, the reliability test of the to-be-tested products of different production batches can be carried out on a plurality of functions at a plurality of test stations under different test conditions, the reliability test of the to-be-tested products of one production batch can be carried out on a plurality of functions at a plurality of test stations under different test conditions, and the reliability test of the to-be-tested products of the same production batch can be carried out at a single test station under a single test condition.

In an embodiment, production equipment, raw materials, methods, environments, and the like used in production of products to be inspected in different production batches may have a certain difference, so that the products to be inspected in different production batches have a certain difference in performance, quality, and the like, and abnormal conditions may also have a difference, and then different rule information needs to be correspondingly set to determine the failure found state of the products to be inspected in different batches, that is, the rule information corresponding to the products to be inspected in different production batches is different, and the rule information corresponding to different production batches is referred to as first rule information for distinction hereinafter.

First rule information corresponding to a production lot may be determined based on second test information obtained in a reliability test of a product to be inspected of the production lot for determining that the product to be inspected is in a failure-undetermined state. Based on the same method, first rule information respectively corresponding to different production batches can be obtained.

Specifically, in the present embodiment, a production lot of the first product to be tested, i.e. a target production lot, is obtained. And acquiring first rule information corresponding to the target production batch from first rule information respectively corresponding to different production batches as target rule information for judging the failure ascertained state of the first product to be detected.

Step A70, acquiring target test conditions of a first product to be detected, and acquiring second rule information corresponding to the target test conditions from second preset rule information corresponding to various test conditions as target rule information, wherein the second rule information is determined based on second test information which is acquired by a product corresponding to the test conditions in a reliability test and is used for judging that the product is in a failure undetected state;

in another embodiment, different test contents, such as an environmental test, a life test, a screening test, a field use test, an identification test, and the like, may be set in each round of the reliability test, and the different test contents include different test conditions. For example, when the environment test is performed, the test conditions of high temperature and high humidity are respectively set to perform the reliability test on the same function of the products to be tested in one production batch, and the bearing capacities of the products to be tested in one production batch to the high temperature environment and the high humidity environment are different, so that the test information obtained by the products to be tested in one production batch under two different test conditions is different. Different rule information needs to be correspondingly set under different test conditions to judge the failure found state of the product to be detected, that is, the rule information corresponding to different test conditions is different, and the rule information corresponding to different test conditions is referred to as second rule information for distinguishing.

Second rule information corresponding to a test condition may be determined based on second test information obtained by performing a reliability test on a product to be tested under the test condition for determining that the product to be tested is in a failure undetermined state.
