Description

Technical Field

[0001] The present invention belongs to the technical field of industrial production monitoring, and in particular relates to an industrial production anomaly detection method based on information mask and a related device. Background Art

[0002] In the existing industrial production process, anomaly detection is a key link in quality control and production efficiency optimization. It can not only help companies detect abnormal conditions on the production line in a timely manner and prevent potential product defects, but also reduce downtime and resource waste, significantly improving overall operational efficiency.

[0003] Industrial production systems are becoming increasingly complex, and the scale of data is growing explosively. Existing traditional anomaly detection methods are gradually exposing their limitations. Explanation: Most of the existing traditional anomaly detection methods rely on artificially set fixed thresholds or simple statistical methods based on historical data, such as standard deviation, mean and other statistics to determine whether the data deviates from the normal range. The above existing methods can still play a certain role in the production environment with relatively stable and clear data characteristics; however, in today's highly dynamic and changeable industrial scenarios, the data in the industrial production process often presents nonlinear, high-dimensional, strong noise and other characteristics, making it difficult for fixed thresholds and simple statistical methods to effectively capture subtle changes and complex patterns in the data, resulting in frequent missed detections and false detections, and greatly reducing the detection effect and generalization ability.

[0004] To sum up, with the advancement of technology, especially the integrated application of technologies such as artificial intelligence and big data, industrial anomaly detection is gradually moving towards a new stage of greater intelligence and precision. In order to adapt to the anomaly detection needs of different industrial environments, it is urgent to develop a new industrial production anomaly detection solution. Summary of the invention

[0049] In order to make the purpose, technical solutions and advantages of the present invention clearer, the technical solutions in the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments and technical solutions are only part of the embodiments of the present invention, not all of the embodiments.

In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device including 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.

[0051] See also Figure 1 , an industrial production anomaly detection method based on information mask disclosed in an embodiment of the present invention comprises the following steps:

[0052] Step 1, obtaining the original industrial signal data to be detected in industrial production;

[0053] Step 2, based on the original industrial signal data obtained in step 1, reconstruct the data using the reconstruction model to obtain a data reconstruction result;

[0054] Step 3, obtaining a reconstruction error between the data reconstruction result and the original industrial signal data, and comparing the reconstruction error with a preset reconstruction error threshold, and obtaining an industrial production anomaly detection result based on the comparison result;

[0055] In the reconstruction model, a mask network layer is provided to avoid the original industrial signal data X=[x1,x2,…,x i ,…,x n ] to data reconstruction results In the mapping process, the i-th original data point x i To the i-th reconstructed data point Direct mapping.

[0056] The embodiment of the present invention discloses a new method for detecting anomalies in industrial production, which combines information masking and data reconstruction technology, aiming to improve the wide adaptability of anomaly detection in industrial signal data. Specifically, the embodiment of the present invention proposes an anomaly detection scheme based on information masking, which is specially designed for industrial production environment and can identify abnormal situations in the production process in real time and effectively. The core of the method is to use data reconstruction and information masking technology to process the input industrial signal data, thereby realizing anomaly detection. On the basis of data reconstruction, the present invention implements masking operation on part of the information, that is, hides or modifies part of the data to avoid the model directly relying on the simple mapping relationship between the reconstructed data and the original data. This step prompts the model to learn deeper and more generalized data patterns; through information masking technology, the model is forced to learn the general laws between data rather than the characteristics of specific samples, thereby improving its adaptability in different workshops, production lines and even industrial environments; the combination of information masking and data reconstruction enables the model to capture more subtle abnormal signals, improving the accuracy and sensitivity of anomaly detection.

[0057] To further explain, the model provided by the embodiment of the present invention can effectively detect abnormal individuals in industrial signals. When the model is migrated from experimental data to similar products in different workshops during deployment, the detection performance is better.

[0058] See also Figure 2 and Figure 3 In one embodiment of the present invention, further explanation of the reconstruction model is as follows:

[0059] The input data of the reconstruction model is the original reconstructed data, and the output target data is the data reconstruction result of the original reconstructed data. The input and output should be as consistent as possible. This model is trained on normal data and has not learned the pattern of abnormal samples. Therefore, the reconstruction error when reconstructing abnormal samples will become higher, resulting in poor reliability. In view of the problems existing in the above-mentioned existing reconstruction models, in the reconstruction model of the embodiment of the present invention, different from the scheme of using each dimension of the input data to construct a mapping to the output in the existing traditional network, the technical solution of the present invention sets a mask network layer to avoid the direct mapping of each data segment in the reconstructed data to the data segment corresponding to the data reconstruction result, forcing the model to learn a more general data pattern to improve the detection level.

[0060] Specifically, first, the original reconstructed data is divided into multiple small data segments, such as [x1, x2, x3] is a data segment of length 3; then, a convolution kernel is used to perform a convolution operation on the data segment, and a mask network layer is inserted between the data segment and the convolution kernel. The input of the mask network layer is the data segment, and the output is the masked data segment. For example, the input is [x1, x2, x3], and the output is [x1, 0, x3]. Through this information masking processing method, the data point in the middle of the data segment is lost; the convolution kernel and the data segment have the same size, which ensures that the convolution kernel will not move on the data segment, and the output of the convolution kernel It is a number after the convolution operation; the model uses multiple convolution kernels to perform convolution operations with the data segment at the same time. The results of multiple convolutions will be flattened to form a new sequence. For example, after the data segment [x1, x2, x3] passes through the mask network layer and the convolution operation, a new sequence [y1, y2, y3] is obtained. The new sequence does not contain the information of the x2 data point in the input data segment sequence, which results in information discarding. By masking part of the data, the model is forced to reconstruct the result not to depend on the reconstructed data, but to learn a more global and general data pattern. The new sequence obtained after flattening the convolution result is reduced to 1 dimension using multiple linear layers to obtain the reconstructed data. In addition, by placing multiple mask network layers and convolution kernels in parallel, we can reconstruct the following in the order of [x1,x2,x3], [x2,x3,x4]:

[0061] To explain further, the original reconstructed data sequences x1 and x n Then we use the operation of adding 0 to the beginning part. Specifically, we design [0,x1,x2] and [x n-1 ,x n ,0] is used to get and Will arrive Arrange them in sequence to get the complete data reconstruction result.

[0062] See also Figure 4 In one embodiment of the present invention, a reconstruction error between a data reconstruction result and the original industrial signal data is obtained, and the reconstruction error is compared with a preset reconstruction error threshold, and in the step of obtaining an industrial production anomaly detection result based on the comparison result,

[0063] Original industrial signal data X = [x1, x2, ..., x i ,…,x n ] and data reconstruction results The reconstruction error is expressed as ||·||2 represents the Euclidean norm. If the calculated reconstruction error is greater than a preset reconstruction error threshold, the original industrial signal data is called abnormal data.

[0064] In a further preferred technical solution, the preset reconstruction error threshold is designed as follows: the reconstruction error of each sample is arranged from small to large, and α% of the samples in the last part are abnormal.

[0065] In a specific embodiment of the present invention, taking a specific industrial production scenario as an example, the signal data collected on the production line is first subjected to an information masking operation, and then input into a reconstruction model for training; after the model training is completed, the newly collected data is monitored in real time through an abnormal scoring mechanism to promptly discover and report abnormal situations.
