Description

Technical Field

[0001] The present application relates to the field of failure risk determination, and in particular, to a method, device, storage medium and electronic device for determining the failure risk of an event. Background Art

[0002] When modern factories produce products, it is necessary to conduct potential failure mode analysis on the production line design and production process corresponding to each product. Through potential failure mode analysis, the places where problems may occur during the production of the product are listed one by one. Then, by analyzing the data generated during the production of each product, the failure risk of the production line design and production process corresponding to the product is obtained, so as to improve the product's assembly line design and production process in time, so that the process can proceed smoothly, avoid producing more defective products, and reduce the company's losses.

[0003] However, the current method of conducting potential failure mode analysis on production line design and production process is usually for process personnel to manually compile failure mode analysis tables. During the compilation process, the failure modes need to be filled in the potential failure mode analysis table one by one, and the production data needs to be manually summarized and analyzed to finally obtain the corresponding failure risk of the product. However, the manual compilation method is mostly based on manual experience, and errors may occur in the design of failure modes. At the same time, errors may occur in the analysis results of production data analysis, resulting in incorrect judgment of the failure risk of the product production process, causing the company to bear unnecessary losses.

[0021] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0022] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0023] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequential order. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present application described here. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device comprising a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0024] According to an embodiment of the present application, a method for determining the failure risk of an event is provided.

[0025] Figure 1 1 is a flow chart of a method for determining the failure risk of an event provided in an embodiment of the present application. Figure 1 As shown, the method comprises the following steps:

[0026] Step S102, obtaining a process template corresponding to the target event and a plurality of failure mode information corresponding to the target event, wherein the process template includes process information required to complete the target event, and the failure mode information is used to characterize the failure phenomenon information corresponding to the process of the target event.

[0027] Specifically, the target event may be the production of product A, where product A needs to be produced using an assembly line. Each assembly line contains multiple processes, and each process may correspond to multiple failure mode information. For example, product A may be a water cup, which may include processes such as producing a cup lid, producing a cup body, producing a handle, and coloring. There may be multiple failure modes in the process of producing the cup lid, such as cracking of the cup lid, oversize of the cup lid, etc.

[0028] It should be noted that the method for determining the failure risk of an event provided in this embodiment can first obtain a process template corresponding to the target event, wherein the process template contains all the process contents corresponding to the target event. For example, the process template corresponding to product A may include processes such as producing a cup lid, producing a cup body, producing a handle, and coloring. At the same time, multiple failure mode information corresponding to the target event will also be obtained. For example, if product A is a water cup, relevant failure mode information about the cup lid, cup body, handle, and color will be obtained.

[0029] Step S104 , matching the multiple failure mode information with the process information in the process template to obtain a target template, and determining the failure index value corresponding to each failure mode information.

[0030] Specifically, after obtaining the process template and multiple failure mode information corresponding to the target event, each failure mode information and the process corresponding to the failure mode information are matched and connected to generate a target template corresponding to the target event, wherein the target template can be used to judge the failure risk of the target event. In each failure mode information, the failure cause and failure index value of each failure mode are included. For example, a failure mode corresponding to product A is: the crack of the cup cover exceeds 1 cm, and the failure index value is 450, which means that there is a crack on a cup cover, and when the crack exceeds 1 cm, the cup cover is a defective product, that is, it is failed, and when the actual index value is greater than 450, it means that the failure mode of the work station has a failure risk, that is, there is a high risk of defective products in production and outflow, etc., and it is necessary to make corresponding improvements in product design and product production for the failure mode of the work station to avoid the occurrence of the failure risk.

[0031] Step S106, obtaining characteristic values ​​corresponding to the failure mode information matched by each process in the target event, comparing each characteristic value with the failure index value corresponding to the failure mode information to obtain multiple comparison results, and determining the failure risk result of the target event based on the multiple comparison results.

[0032] Specifically, the characteristic values ​​corresponding to each failure mode in each process of the target event in actual production are obtained, wherein the characteristic values ​​may include the severity caused by the failure, the frequency of failure, and the difficulty of detecting the failure phenomenon, that is, the detection degree. After obtaining the characteristic values, the characteristic values ​​can be calculated and compared with the corresponding failure index values, or the characteristic values ​​can be compared with the corresponding failure index values, and the failure risk results corresponding to each process can be obtained by different methods, thereby obtaining the failure risk results corresponding to the target event.

[0033] For example, a failure mode corresponding to product A is: the crack on the cup cover exceeds 1 cm, and the failure index value is 450. In the actual production process, the severity of the crack on the cup cover exceeding 1 cm is 7, the frequency of occurrence is 4, and the detection degree is 4. The characteristic index value can be obtained by multiplication as 112, which is less than the failure index value of 450. This proves that the current production method and the inspection method for cup cover cracks exceeding 1 cm do not have risks, and the result is normal.

[0034] The method for determining the failure risk of an event provided in the embodiment of the present application is to obtain a process template corresponding to a target event and multiple failure mode information corresponding to the target event, wherein the process template includes the process information required to complete the target event, and the failure mode information is used to characterize the failure phenomenon information corresponding to the process of the target event; multiple failure mode information is matched with the process information in the process template to obtain the target template, and the failure index value corresponding to each failure mode information is determined; the characteristic value corresponding to the failure mode information matched by each process in the target event is obtained, each characteristic value is compared with the failure index value corresponding to the failure mode information, and multiple comparison results are obtained, and the failure risk result of the target event is determined according to the multiple comparison results. The problem that the failure risk in the product production process cannot be obtained quickly and accurately in the related art is solved. By automatically matching the template and the failure mode, a risk judgment template is generated, and the failure risk is judged by automatically calculating and comparing the characteristic value to obtain the failure risk result, so as to achieve the effect of quickly and accurately obtaining the failure risk result in the product production process, thereby rectifying the product design and production method.

[0035] Optionally, in the method for determining the failure risk of an event provided in an embodiment of the present application, obtaining a process template corresponding to a target event and multiple failure mode information corresponding to the target event includes: identifying keywords of the target event; searching a first database for a process template corresponding to the keyword, wherein the first database stores multiple process templates, and each process template contains preset process information; searching a second database for failure mode information corresponding to the keyword, and obtaining multiple failure mode information corresponding to the target event, wherein the second database stores multiple failure mode information.

[0036] Specifically, one or more keywords corresponding to the target event are first input, and the process template corresponding to the keyword is obtained in the first database through the keyword, and all failure mode information corresponding to the keyword is obtained in the second database. For example, if the target event is the production of water cup A, the keyword can be a water cup including a cup lid and a handle, then the process template corresponding to the process of producing water cup A can be obtained from multiple process templates in the first database, and the failure mode information corresponding to the processes of producing cup lid, producing cup body, producing handle, etc. can be selected in the second database, and the failure mode information related to the cup lid in the failure mode information can be matched with the process of producing the cup lid in the process template, and the failure mode information related to the cup body in the failure mode information can be matched with the process of producing the cup body in the process template, so as to obtain the target template corresponding to the production of water cup A.

[0037] Optionally, in the method for determining the failure risk of an event provided in an embodiment of the present application, each eigenvalue includes multiple sub-eigenvalues, and each eigenvalue is compared with a failure index value corresponding to the failure mode information to obtain multiple comparison results, including: multiplying all sub-eigenvalues ​​in the same eigenvalue to obtain a target eigenvalue, and comparing the target eigenvalue with the failure index value corresponding to the eigenvalue to obtain a comparison result.

[0038] Specifically, after obtaining the eigenvalue corresponding to each failure mode information, the sub-eigenvalues ​​in the eigenvalue can be multiplied, and the failure index value corresponding to each failure mode information can be obtained, and the calculation result is compared with the corresponding failure index value to obtain a comparison result, wherein the failure index value can be a preset RPN (Risk Priority Number risk coefficient value).

[0039] For example, a failure mode corresponding to product A is: the cup height is less than 50cm, and the preset RPN is 300. In the actual production process, the severity of the cup height less than 50cm is 8, the frequency of occurrence is 2, and the detection degree is 5. The characteristic index value can be obtained by multiplication to be 80, which is less than the preset RPN. This proves that the current production method and the inspection method for the cup height less than 50cm have no risks, and the result is normal.

[0040] Optionally, in the method for determining the failure risk of an event provided in an embodiment of the present application, determining the failure index value corresponding to each failure mode information includes: obtaining all failure mode information in the target template, and obtaining a preset template containing at least all failure mode information from a third database to obtain a standard template, wherein the third database stores multiple preset templates, each preset template includes preset process information, preset failure mode information and a failure index value corresponding to each preset failure mode information, and each failure index value includes multiple sub-indicator values; obtaining the failure index values ​​corresponding to all failure mode information in the target template from the standard template; each characteristic value includes multiple sub-characteristic values, and each characteristic value is compared with the failure index value corresponding to the failure mode information to obtain multiple comparison results, including: determining the sub-indicator value of each sub-characteristic value in each characteristic value under the corresponding failure index value, and comparing each sub-characteristic value with the corresponding sub-indicator value to obtain a group of sub-comparison results, and determining a group of sub-comparison results as one comparison result.

[0041] Specifically, after obtaining the target template, all failure mode information in the target template can be obtained, and a preset template containing all failure mode information in the target template can be obtained in the third database. For example, there are 20 failure mode information in the target template. At this time, search in the third database and try to obtain a preset template, wherein the preset template contains 20 failure mode information in the target template. For example, the preset template contains 30 failure mode information, among which 20 failure mode information are the same as the 20 failure mode information in the target template.

[0042] It should be noted that after obtaining the preset template corresponding to the target template, the AP (Active Priority) value in the preset template is obtained and compared with the characteristic value in the target template, wherein the preset template may be an AP data table, and the AP value may be a plurality of sub-indicator values ​​in the failure indicator value corresponding to each preset failure mode information. Each sub-indicator value is compared with the sub-characteristic value in the characteristic value corresponding to the corresponding failure mode information in the target template, so as to obtain the failure risk result corresponding to each failure mode information.

[0043] For example, a preset failure mode information in the preset template is: cup height is less than 50cm, severity is 7, frequency of occurrence is 1, and detection is 6. The corresponding preset failure mode information in the target template is: cup height is less than 50cm, severity is 8, frequency of occurrence is 2, and detection is 4. The sub-feature value of the target template is compared with the corresponding sub-indicator value in the preset template. The failure mode information with the sub-feature value greater than the sub-indicator value can be judged as a risk failure mode. Since the severity and frequency of the cup height less than 50cm are higher than the corresponding sub-indicator value in the preset template, the failure mode information is judged to be a risk failure mode. After matching each failure mode information in the target template, multiple matching results are combined to obtain the failure risk judgment result of the target event.

[0044] Optionally, in the method for determining the failure risk of an event provided in an embodiment of the present application, in the process of obtaining all failure mode information in the target template and obtaining a preset template containing at least all failure mode information from a third database, if the preset template containing at least all failure mode information cannot be obtained, an alarm information is generated.

[0045] Specifically, when obtaining a preset template from a third database, if the preset template corresponding to the target template cannot be obtained, an alarm message, such as a pop-up message, is issued to inform the user that the preset template cannot be obtained, and the product of multiple sub-feature values ​​in the target template can be automatically calculated, and the calculation result is compared with the corresponding preset RPN to obtain a comparison result.

[0046] Optionally, in the method for determining the failure risk of an event provided in an embodiment of the present application, after matching multiple failure mode information with process information in a process template to obtain a target template, the method further includes: determining whether the matching result between each process information and the matched failure mode information is correct; if the matching result is incorrect, obtaining the target process information and target failure mode information corresponding to the matching result, deleting the target failure mode information, and re-obtaining the failure mode information from the second database based on the target process information, and adding the acquired failure mode information to the target template to obtain an updated target template.

[0047] Specifically, after matching and connecting each failure mode information with the process corresponding to the failure mode information and generating a target template corresponding to the target event, it is necessary to check whether the target template is correct. When it is found that some processes in the target template and the failure mode information are mismatched, the mismatched failure mode information is deleted, and a check is made in the second database to see whether there is any failure mode information corresponding to the mismatched process of the target event. If there is any corresponding failure mode information, the failure mode information is obtained and matched with the process. If there is no corresponding failure mode information, the generation of the target template is completed.

[0048] It should be noted that, when there is no corresponding failure mode information, new failure mode information can be manually added to the third database, and the new failure mode information is matched with the process template to obtain the target template.

[0049] Optionally, in the method for determining the failure risk of an event provided in an embodiment of the present application, after determining the failure risk result of the target event based on multiple comparison results, the method also includes: determining the process with failure risk when the failure risk result indicates that the target event is at risk; obtaining a corrected characteristic value corresponding to the process with failure risk after correction; comparing each corrected characteristic value with the failure indicator value corresponding to the failure mode information to obtain multiple updated comparison results, and determining the failure risk result of the target event based on the multiple updated comparison results.

[0050] Specifically, after obtaining the failure risk results, the processes with failure risks and the failure mode information corresponding to the processes are determined according to the failure risk results, and the product design and process design are optimized and changed according to the failure mode information, and the corrected feature values ​​corresponding to each failure mode information are obtained after optimization. And in the target template, it is judged whether the corrected production method still has failure risks according to the corrected feature values.

[0051] Figure 2 is a flow chart of a method for determining failure risk of an optional event provided in an embodiment of the present application, such as Figure 2As shown, first input one or more keywords corresponding to the target event, obtain the process template corresponding to the keyword in the first database through the keyword, and obtain all the failure mode information corresponding to the keyword in the second database. Then, match the multiple failure mode information with the process information in the process template to obtain the target template, and determine the failure index value corresponding to each failure mode information.

[0052] Furthermore, the characteristic value of the target event is obtained, and the RPN calculation or AP data table comparison method is selected to calculate or compare the characteristic value, so as to obtain the failure risk judgment result corresponding to the target event, and judge whether the target event has a failure risk based on the result. If there is a failure risk, the product design or production method is rectified, and the RPN calculation or AP data table comparison is re-performed to obtain a new failure risk judgment result. If the new failure risk judgment result still shows that there is a failure risk, the product design and production process are re-rectified, and the target template corresponding to the target event is regenerated.

[0053] It should be noted that when it is judged that the corrected production method still has a failure risk based on the corrected characteristic values, it is necessary to re-optimize the design and production of the product. At the same time, a new target template needs to be created, and the new characteristic values ​​after optimization need to be judged through the new target template to obtain a new failure risk judgment result for the target event.

[0054] It should be noted that the steps shown in the flowcharts of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and that, although a logical order is shown in the flowcharts, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0055] The embodiment of the present application also provides a device for determining the failure risk of an event. It should be noted that the device for determining the failure risk of an event in the embodiment of the present application can be used to execute the method for determining the failure risk of an event provided in the embodiment of the present application. The device for determining the failure risk of an event provided in the embodiment of the present application is introduced below.
