Embodiment approach

[0064] see image 3 , as an implementation manner, S40 specifically includes:

[0065] S401. Determine whether each characteristic data in the characteristic data set obeys a normal distribution;

[0066] In the specific implementation process, each characteristic data in the characteristic data set belongs to the production process of different types of products, and does not necessarily obey the normal distribution. In order to generate the production process of different types of products into the same control chart, it is necessary to generate Before making the control chart, ensure that the characteristic data obey the normal distribution. Therefore, it is first necessary to judge whether each characteristic data in the characteristic data set obeys a normal distribution.

[0067] Specifically, the probability paper can be used to obtain the normality correlation coefficient of each characteristic data to judge whether the data obey the normal distribution. If not, exe...

Abstract

The embodiment of the invention discloses a product production process quality control method and device, equipment and a storage medium, and the method comprises the steps: obtaining a characteristic data set of a production process, and the characteristic data set comprises the characteristic data of a plurality of production processes of different products; constructing a control chart about the plurality of production processes based on the characteristic data set; judging whether each production process is in a controlled state or not based on the control chart; and inputting target characteristic data corresponding to the target production process into the weighted online sequential extreme learning machine obtained by training to obtain an abnormal mode result of the target production process. The technical problem that the recognition effect of the abnormal mode of the control chart of the multi-variety and small-batch products is poor is solved, and the recognition accuracy of the abnormal mode of the control chart in the production process of the multi-variety and small-batch products is improved.

Description

technical field [0001] This application relates to the technical field of product quality control, in particular to a product production process quality control method, device, equipment and storage medium. Background technique [0002] With the continuous increase in the variety and quantity of industrial products, the manufacturing industry has gradually changed from the traditional mass production mode to the multi-variety and small-batch production mode. In order to ensure the final product quality, it is necessary to carry out quality control during the manufacturing process. To determine whether there is an abnormality in the manufacturing process. When performing quality control, SPC (Statistical Process Control) control chart technology is a widely used method. According to the state of the control chart, it can be judged whether the production process is abnormal and reveals potential quality problems in the manufacturing process. Therefore, the effective identific...
