[0049] like Figure 1 As shown, the embodiment of the present application provides a quality monitoring method for an automobile industry chain, including the following method steps:
[0050] S201: Obtain historical vehicle fault data.
[0051] Specifically, obtain the historical vehicle parts failure data and the historical vehicle assembly failure data. Automobile quality failures are usually caused by failures of the parts themselves and assembly failures caused by the assembly process. Therefore, whether it is the manufacturer's own production process or the after-sales process, a large amount of failure data will be accumulated to facilitate maintenance and improvement. Therefore, the failure data can be read directly from the third-party platform; the corresponding failure data can also be obtained from the third-party platform, and a failure database is established after aggregation. The failure database includes all historical failure data of the entire production chain of a specific model. For different models, other special failure databases are established to correspond to the production chain of the model.
[0052] S202: Acquire corresponding vehicle production links according to the historical fault data.
[0053] Historical failure data includes defective parts and unqualified assembly data. Depending on the cause of the failure, each corresponds to one or more vehicle production links. When enough sample data is accumulated, the historical failure data can show the vehicle production link where the failure data occurs.
[0054] In a preferred embodiment, the product failure rate of the corresponding vehicle production link is calculated based on the historical failure data; the product failure rates of all the vehicle production links are sorted to obtain the vehicle production link with the highest product failure rate within a preset range.
[0055] Specifically, there are many reasons for automobile failures, and the corresponding production links may be large in number. If all vehicle production links that cause failure data are monitored, the manpower workload and data statistics will be very large and complicated. Therefore, in order to improve the monitoring efficiency while ensuring accurate positioning of the monitoring range, it is chosen to sort the product failure rates of the vehicle production links. The product failure rate of the vehicle production link is obtained by calculating the ratio of the number of product failure data in the vehicle production link to the total output of the vehicle production link. Sort the product failure rates of all vehicle production links after calculation, and select the relevant vehicle production links with higher product failure rates for subsequent quality monitoring steps. For example, it can be preset to obtain relevant vehicle production links with product failure rates in the top 20% for quality monitoring.
[0056] According to practical experience, the probability of failure in different vehicle production links is different. In general, most of the failures at the end of the vehicle production chain do not run through the entire production chain, but are concentrated in a few production links. For different models, if you want to ensure that the preset range of product failure rate is within a reasonable range, you should count the failure rate of all production links in the production chain of the model and adjust it according to the actual situation. In a specific example, suppose that according to statistics, there are 100 production links with failures in the production chain of a certain model, among which the product failure rate of link A is 30%, the product failure rate of link B is 20%, the product failure rate of link C is 15%, the product failure rate of link D is 13%, and the product failure rate of link E is 10%; from the above, it can be seen that the product failure rate of the five links A, B, C, D, and E has exceeded 80%, and the other 95 types of failures are less than 20%. At this time, if the preset fixed monitoring range is directly used, the monitoring range may be expanded, and some production links with relatively low product failures will be included in the monitoring range, which will waste human resources to a certain extent and reduce the efficiency of quality monitoring. Therefore, for the above example, quality monitoring can be limited to the relevant vehicle production links with failure rates in the top 5%. This will not only concentrate quality monitoring of the automobile production chain on links with high failure rates, but also improve quality monitoring efficiency.
[0057] S203: Acquire the test data of the vehicle production process and determine whether there is any test data that does not meet the quality inspection requirements.
[0058] Since the entire process of automobile production has high requirements for production quality, a large number of performance tests are included in the production and subsequent assembly of automobile parts, and relevant test data are saved. Therefore, the existing test data of the vehicle production process can be retrieved to judge whether the quality is qualified or not based on the existing test data. If there is no relevant test data, the data on the production line can be directly collected in real time as test data. If no test data that does not meet the quality inspection requirements is found after testing according to the specified quality qualification index data, the qualified test data will be backed up and stored to facilitate quick troubleshooting in the future.
[0059] S204: If there is the test data that does not meet the quality inspection requirements, the unqualified product information corresponding to the test data is obtained and stored in the defective database.
[0060] Specifically, the defective parts or assembly parts are identified, and their defective data are stored in a defective database; wherein each defective part or assembly part is assigned an identity ID as an identifier to facilitate quick search in the defective database.
[0061] In a preferred embodiment, in the subsequent production links, problems that may cause downstream production failures due to unqualified products should also be pre-checked. Specifically, the incoming material information of the downstream production link of the automobile industry chain is obtained; according to the defect database, it is determined whether the unqualified product information exists in the incoming material information; if the unqualified product information exists, a warning message is generated. The warning information includes but is not limited to: defective, once tested defective but retested after repair, and reminder to replace, etc.
[0062] In a preferred embodiment, as the test data increases, the historical component failure data and historical assembly failure data are also updated, so the database storing the relevant data should be updated in a timely manner. At the same time, a data encryption algorithm module should be set for the relevant database to prevent the data from being tampered with.
[0063] In a preferred embodiment, if the failure rate of a certain production link is continuously monitored to be high, for example, if the failure rate is set to be continuously higher than 5-10%, a shutdown inspection warning message is issued to instruct relevant staff to troubleshoot the problem in the production link, starting from fundamental issues such as raw materials and design to avoid recurrence of failures.
[0064] The embodiment of the present application provides a quality monitoring method for the automobile industry chain, which obtains the historical fault data of the vehicle; then obtains the corresponding vehicle production link based on the historical fault data; and simultaneously obtains the test data of the vehicle production link to determine whether there is the test data that does not meet the quality inspection requirements; if there is the test data that does not meet the quality inspection requirements, the unqualified product information corresponding to the test data is obtained and stored in the defective database. Based on the data information in the defective database, other faults that may be caused by unqualified products in the downstream production links can be checked to prevent the occurrence of faults in advance. The embodiment of the present application realizes the pre-prevention and in-process management of automobile production quality monitoring from the perspective of the entire industry chain, which can effectively improve the efficiency of vehicle quality inspection and ensure the quality of finished products of the terminal products of the production chain.
