Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

It should be noted that the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or server that includes a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or modules that are not explicitly listed or inherent to these processes, methods, products or devices.

Embodiment 1, as shown in FIG1 , the present application provides a method for monitoring the working state of a high-speed laser film-making and slitting machine, the method comprising:

Receive the predetermined working parameters of the high-speed laser film-making and slitting machine, and obtain the predetermined control plan of the equipment and the predetermined working environment information of the equipment.

In an embodiment of the present application, when the high-speed laser film-making and striping machine is ready to run, the system terminal will receive a series of predetermined operating parameters of the device. These parameters are the benchmarks for the device to perform tasks according to specific requirements, such as laser power, cutting speed, material thickness, etc. Based on these predetermined operating parameters, the system terminal obtains a predetermined control scheme for the device. This scheme specifies how the device should adjust the status of each component during operation to ensure that the overall performance is optimized. At the same time, the predetermined working environment information of the device is also obtained, including external factors such as temperature, humidity, vibration, etc. that may affect the operation of the device. By understanding this information, the device can be appropriately adjusted or configured in advance to cope with possible environmental challenges.

The component characteristics are disassembled according to the predetermined control scheme of the equipment to obtain the predetermined control decision of each component of the high-speed laser film-making and slitting machine.

In one embodiment, after obtaining the predetermined control scheme of the high-speed laser film-making and striping machine, the system terminal performs component feature disassembly on the scheme, that is, decomposing the complex control process of the entire device into specific control tasks of each component, such as the laser, cutting head, transmission system, etc. Through component feature disassembly, the system terminal can understand the role of each component in the operation of the device and how to accurately control them according to the predetermined control scheme. After completing the component feature disassembly, the system terminal generates a series of predetermined control decisions for each component. These decisions are the key to the smooth operation of the device according to the predetermined control scheme. They ensure that each component in the device can work together to realize the overall function of the device.

According to the predetermined control decisions of each component, a first component predetermined control decision corresponding to the first component of the high-speed laser film-making and slitting machine is extracted.

In one embodiment, the system terminal randomly extracts a component from the components of the high-speed laser film-making and slitting machine as the first component, and uses the corresponding predetermined control decision as the first component predetermined control decision for subsequent health prediction of the working status of the first component.

The working state health prediction of the first component is performed according to the predetermined working environment information of the equipment and the predetermined control decision of the first component to obtain a first component health state prediction matrix.

In one embodiment, the system terminal performs a health prediction on the working state of the first component based on the predetermined working environment conditions of the device and the preset control strategy of the first component. This prediction process is intended to evaluate in advance whether the first component will be in good operating state in the future. The system terminal generates a health state prediction matrix for the first component through steps such as registration recognition and concentrated interval recognition. This matrix contains information about the health state of the first component in different time periods or under different working conditions in the future, which helps to discover potential problems in advance and optimize the control strategy to ensure the overall performance and stability of the device.

Further, the present application provides a method of performing working state health prediction on the first component according to the predetermined working environment information of the device and the predetermined control decision of the first component to obtain a first component health state prediction matrix, including:

According to the high-speed laser film-making and striping integrated machine, health status monitoring records are retrieved to obtain a first health status monitoring record set corresponding to the first component; the first health status monitoring record set is aligned and identified according to the predetermined working environment information of the equipment and the predetermined control decision of the first component to obtain a first health status prediction alignment space; data cleaning and classification are performed according to the first health status prediction alignment space to obtain multiple health status prediction alignment domains.

Preferably, the system terminal retrieves the health status monitoring records related to the first component according to the operation history of the high-speed laser film-making and striping machine to form a first health status monitoring record set. This first health status monitoring record set reflects the working status of the first component in different time periods and working environments. Subsequently, the system terminal uses the predetermined working environment information of the equipment and the predetermined control decision of the first component as a reference to align and identify the first health status monitoring record set. This process is to construct a first health status prediction alignment space that meets the predetermined requirements by performing weighted alignment calculation on the health status monitoring records in the first health status monitoring record set. This space is a framework for analyzing and comparing the health status data of the first component under the same benchmark. Afterwards, in the first health status prediction alignment space, the system terminal cleans the internal working status monitoring data to remove noise and irrelevant data, and checks whether there are missing values, records the number and location of missing values, and then uses the mean of the five adjacent data to supplement the missing values. After the data cleaning is completed, the system terminal determines the neighborhood size ε and the minimum number of points MinPts as the DBSCAN algorithm input parameters according to actual needs and data characteristics. Then, the distance between each two working state monitoring data after cleaning is calculated according to the Euclidean distance, and then the configured DBSCAN algorithm is used to divide these working state monitoring data into different clusters to obtain multiple health state prediction registration domains. Each registration domain represents a different health state mode that the first component may present under specific working conditions or time periods. This helps to more accurately predict and diagnose the future health status of the first component, providing strong support for maintenance and optimization.

Centralized interval recognition is performed according to the multiple health status prediction and registration domains to obtain multiple health prediction and registration recognition results; and the first component health status prediction matrix is generated according to the multiple health prediction and registration recognition results.

Preferably, after obtaining multiple health status prediction registration domains, the system terminal uses the working status monitoring data in each registration domain as a data point, and applies the K-means clustering algorithm to perform cluster analysis on all working status monitoring data. Among them, the cluster number K value is selected based on the elbow rule. After the clustering is completed, each data point will be assigned to a cluster center. For each cluster center, the corresponding prediction value range, that is, the concentrated interval, is calculated, and then the frequency of each concentrated interval is determined, that is, the proportion of the working status monitoring data in the interval in all working status monitoring data, and the weight of the interval is determined according to the frequency of the interval. The concentrated interval that appears at a high frequency is given a higher weight. Subsequently, the recognition results of each registration domain are integrated, and the concentrated interval of each working status monitoring data is summarized to form multiple health prediction registration recognition results. In the summary process, the system terminal performs weighted calculation on the summarized results by the Bayesian weighted average method to ensure the accuracy of the comprehensive results. Afterwards, based on these health prediction registration recognition results, the system terminal generates a health status prediction matrix of the first component. This matrix is a two-dimensional array, which contains the health status prediction information of the first component at different times or conditions. Each row of the matrix represents a specific time point or condition, while each column represents different health status prediction information. By looking at this matrix, you can quickly understand the health status change trend of the first component and the health problems that may occur under different conditions.

Further, the present application provides registering and identifying the first health status monitoring record set according to the predetermined working environment information of the device and the predetermined control decision of the first component to obtain a first health status prediction registration space, including:

Traverse the first health status monitoring record set and extract the first health status monitoring record, wherein the first health status monitoring record includes the first sample working environment information, the first sample control decision and the first healthy sample working status monitoring information corresponding to the first component; perform a weighted registration analysis on the first health status monitoring record according to the predetermined working environment information of the equipment and the predetermined control decision of the first component to generate a first sample comprehensive registration coefficient.

Optionally, the system terminal traverses the first health status monitoring record set and extracts the first health status monitoring record therefrom. The first health status monitoring record records in detail the first sample working environment information, the first sample control decision and the first healthy sample working status monitoring information corresponding to the first component. Subsequently, the system terminal uses the predetermined working environment information of the equipment and the predetermined control decision of the first component as a benchmark, and performs registration and identification on the first health status monitoring record according to the pre-built environment registration and identification channel and the control registration and identification channel to obtain the corresponding registration coefficient. Afterwards, the obtained registration coefficient is weightedly calculated based on the weighted registration weight condition to generate the first sample comprehensive registration coefficient. This first sample comprehensive registration coefficient reflects the degree of closeness between the actual working environment, control decision and working status in the record and the predetermined ideal state, thereby helping to evaluate the health status of the component.

Determine whether the first sample comprehensive registration coefficient is greater than/equal to the predetermined comprehensive registration coefficient; if the first sample comprehensive registration coefficient is greater than/equal to the predetermined comprehensive registration coefficient, add the first healthy sample working status monitoring information to the first health status prediction registration space.

Optionally, after calculating the first sample comprehensive registration coefficient, the system terminal determines whether the first sample comprehensive registration coefficient is greater than or equal to a predetermined comprehensive registration coefficient. This predetermined comprehensive registration coefficient is a threshold set based on historical experience and expert advice, and is used to measure the degree of compliance between the health status monitoring record and the standards required by the health status prediction registration space. If the first sample comprehensive registration coefficient is greater than or equal to the predetermined comprehensive registration coefficient, it means that the working status monitoring information reflected by the first health status monitoring record matches the requirements of the health status prediction registration space. Therefore, the system terminal adds the first health sample working status monitoring information of the first health status monitoring record to the first health status prediction registration space. The purpose of this is to accumulate more high-quality data in order to more accurately predict and evaluate the health status of components.

Further, the present application provides performing weighted registration analysis on the first health status monitoring record according to the predetermined working environment information of the device and the predetermined control decision of the first component to generate a first sample comprehensive registration coefficient, including:

Based on the twin neural network, the environment registration and recognition channel and the control registration and recognition channel are constructed.

Optionally, in order to perform accurate weighted registration analysis, the system terminal constructs an environmental registration recognition channel and a control registration recognition channel based on the architecture of the twin neural network, including the number of neurons in the input layer, hidden layer and output layer of each self-network, loss function, etc. The core functions of these two channels are to use the characteristics of the twin neural network to identify the similarity between input data, but they differ in training data and target applications. For the environmental registration recognition channel, the system terminal divides the sample device predetermined working environment information, sample working environment information, and sample environment registration coefficient to obtain a training set and a test set. The training set is then divided into multiple small batches, each of which contains multiple pairs of sample device predetermined working environment information, sample working environment information and their corresponding sample environment registration coefficients. For each small batch, the system terminal inputs the paired input samples into the two sub-networks of the environmental registration recognition channel for forward propagation calculation. In the output layer, the Euclidean distance is used to calculate the distance between the embedded vectors output by the two sub-networks, and the predicted value of the environmental registration coefficient is calculated based on the distance. Subsequently, the difference between the predicted environment registration coefficient and the sample environment registration coefficient is calculated using the contrast loss function to obtain the loss value. According to the loss value, the gradient of each parameter in the environment registration recognition channel is calculated by the back propagation algorithm. Then the optimization algorithm SGD is used to update the parameters of the environment registration recognition channel according to the gradient to minimize the loss function. Repeat the above steps until the training round reaches the preset upper limit. After that, the trained environment registration recognition channel is evaluated using the test set, and the environment registration recognition accuracy, recall rate and other indicators of the environment registration recognition channel on unseen data are calculated, and the performance of the environment registration recognition channel under different working environment conditions is analyzed to identify possible deviations and deficiencies. If the evaluation result does not meet the actual needs, the environment registration recognition channel is optimized and adjusted, including adjusting hyperparameters such as learning rate, batch size, loss function weight, and introducing regularization technology to prevent overfitting. Otherwise, the current environment registration recognition channel is output. For the control registration recognition channel, the system terminal uses the same training method as above to train the final control registration recognition channel according to the sample component predetermined control decision, sample control decision, and sample control registration coefficient.

The predetermined working environment information of the device and the first sample working environment information are input into the environmental registration identification channel to generate a first sample environmental registration coefficient; based on the predetermined control decision of the first component and the first sample control decision, according to the control registration identification channel, a first sample control registration coefficient is obtained; based on the weighted registration weight condition, the first sample environmental registration coefficient and the first sample control registration coefficient are weightedly calculated to obtain the first sample comprehensive registration coefficient.

Optionally, after constructing the environment registration recognition channel and the control registration recognition channel, the system terminal takes the predetermined working environment information of the device and the first sample working environment information as input and inputs them into the environment registration recognition channel. The environment registration recognition channel compares and analyzes the two inputs based on the feature representation and similarity measurement method learned during the training process, and outputs the first sample environment registration coefficient, which quantifies the degree of registration between the first sample working environment and the predetermined working environment. Similarly, the system terminal inputs the first component predetermined control decision and the first sample control decision into the control registration recognition channel to generate the first sample control registration coefficient. After obtaining the first sample environment registration coefficient and the first sample control registration coefficient, the system terminal calculates the first sample comprehensive registration coefficient according to the weighted registration weight condition. Among them, the weighted registration weight condition specifies two weights, which correspond to the importance of the first environment registration coefficient and the first control registration coefficient in the calculation of the comprehensive registration coefficient, and the two weights are determined based on historical experience and expert advice. The system terminal calculates the first sample comprehensive registration coefficient by multiplying the two registration coefficients by their corresponding weights and summing them. This coefficient comprehensively considers the alignment of both the working environment and the control decision, providing a more comprehensive basis for subsequent decision-making or evaluation.

The high-speed laser film-making and slitting machine is controlled based on the predetermined control decisions of each component, and the high-speed laser film-making and slitting machine is monitored in real time through a sensor monitoring network to obtain the working status monitoring information of the first component.

In one embodiment, the system terminal guides and controls the operation of the high-speed laser film-making and striping machine according to the predetermined control decisions of each component. Each component in the high-speed laser film-making and striping machine will follow the decision content to perform its specific function to ensure that the entire device can operate in a coordinated and efficient manner. In order to grasp the operating status of the high-speed laser film-making and striping machine in real time and discover potential problems in a timely manner, the system terminal collects various real-time data such as temperature, pressure, vibration, speed, etc. based on the deployed sensor monitoring network. The data collected by these sensors will be summarized by the system terminal to generate the first component working status monitoring information, which reflects in detail the current working status, performance parameters and possible abnormal conditions of the high-speed laser film-making and striping machine.

Based on the health status prediction matrix of the first component and according to the working status monitoring information of the first component, risk prediction is performed on the first component to generate a first component status risk coefficient.

In one embodiment, the system terminal organizes and transforms the working status monitoring information of the first component to obtain the first component status monitoring matrix corresponding to the working status monitoring information of the first component. Subsequently, the first component status monitoring matrix and the first component health status prediction matrix are evaluated for deviation depth, and the deviation depth evaluation results are compared with predetermined requirements. If the deviation depth evaluation results meet the predetermined requirements, the system terminal performs risk prediction on the deviation analysis results of the first component status monitoring matrix and the first component health status prediction matrix based on the first component risk prediction channel to generate a first component status risk coefficient. This first component status risk coefficient is a quantitative indicator that reflects the health status risk level of the first component at present and in the future. If the risk coefficient is high, it means that the first component has a higher risk of failure. On the contrary, it indicates that the first component is currently in a relatively healthy state.

Further, the present application provides a method for performing risk prediction on the first component based on the health status prediction matrix of the first component and according to the working status monitoring information of the first component to generate a first component status risk coefficient, including:

Organizing the first component working status monitoring information and establishing a first component status monitoring matrix; performing deviation analysis based on the first component health status prediction matrix and the first component status monitoring matrix to obtain a first component status health deviation analysis result; performing deviation depth evaluation based on the first component status health deviation analysis result to obtain a first component health deviation depth coefficient;

Preferably, the system terminal comprehensively organizes the obtained first component working state monitoring information, which includes the measured values of multiple parameters such as temperature, pressure, vibration frequency, etc. at different time points. By arranging these information in the same format and order as the first component health state prediction matrix, a first component state monitoring matrix is established. This matrix is a data set that reflects the working state of the first component in real time, and provides a basis for subsequent analysis. Subsequently, the first component health state prediction matrix and the first component state monitoring matrix are subjected to deviation analysis to find the difference or deviation between the current monitoring state and the predicted health state. In the process of deviation analysis, the system terminal first aligns the time node in the first component health state prediction matrix with the time node in the first component state monitoring matrix to ensure that the two are compared in the same time frame, and then ensures that the parameter items in the prediction matrix and the monitoring matrix correspond one to one, so as to perform direct comparative analysis later. Subsequently, for each parameter item, the absolute difference between the monitoring value and the predicted value, that is, the deviation degree, is calculated, and each calculated deviation degree is compared with the deviation threshold value to determine which parameter monitoring values exceed the threshold range of the predicted value, and obtain the first component state health deviation analysis result, which reveals the mismatch between the current health state of the first component and the predicted health state. Afterwards, the system terminal traverses the obtained health deviation analysis results of the first component state. In each traversal, the traversed deviation is compared with the depth deviation threshold, and the deviation greater than or equal to the depth deviation threshold is determined as the depth deviation. Among them, the deviation threshold and the depth deviation threshold are set according to the characteristics and operating requirements of the first component, and are used to measure the degree of deviation. Then, the system terminal assigns a weight to each deep deviation based on the importance of the indicators represented by these deep deviations, combined with historical experience and expert advice. Finally, each deep deviation is multiplied by the corresponding weight, and the results are accumulated to calculate the health deviation depth coefficient of the first component. This coefficient reflects the degree to which the health state of the first component deviates from the normal level. The higher the coefficient, the deeper the deviation and the worse the health state of the component.

Determine whether the health deviation depth coefficient of the first component is greater than/equal to a predetermined health deviation depth coefficient; if the health deviation depth coefficient of the first component is greater than/equal to the predetermined health deviation depth coefficient, activate a pre-constructed first component risk prediction channel; based on the health deviation analysis result of the first component state, obtain the first component state risk coefficient according to the first component risk prediction channel.

Preferably, after obtaining the health deviation depth coefficient of the first component, the system terminal compares the health deviation depth coefficient of the first component with the predetermined health deviation depth coefficient to determine whether the health status of the first component has reached a level that requires special attention. If the health deviation depth coefficient of the first component is greater than or equal to the predetermined health deviation depth coefficient, it means that the health status of the first component has or is about to exceed the acceptable range, and there is a high risk. At this time, the system terminal activates a pre-designed risk prediction channel. This channel contains a series of preset models for analyzing and predicting the risks that the first component may face. After the risk prediction channel is activated, the system terminal calculates a specific risk coefficient, namely the first component state risk coefficient, based on the health deviation analysis results of the first component state through the risk prediction channel. This risk coefficient quantifies the degree of risk that may be brought about by the current state of the first component, and provides a basis for subsequent decision-making and response.

Further, the present application provides a method for obtaining a risk coefficient of the first component state based on the first component state health deviation analysis result and according to the first component risk prediction channel, including:

The first component risk prediction channel includes K risk prediction models corresponding to the first component, where K is a positive integer greater than 1.

Optionally, in order to calculate the risk coefficient of the first component state, the system terminal constructs a first component risk prediction channel, which includes K risk prediction models corresponding to the first component, where K is a positive integer greater than 1. In the process of constructing the first component risk prediction channel, the system terminal first obtains K groups of sample state health deviation analysis results and K groups of sample risk prediction coefficients, and each sample risk prediction coefficient corresponds to a group of sample state health deviation analysis results. Subsequently, the system terminal pre-sets a neural network framework, including setting the number of neurons in the input layer, hidden layer, and output layer, setting ReLU as the activation function, setting the mean square error as the loss function, etc. After the neural network framework is set, the system terminal randomly extracts a group of sample state health deviation analysis results and a corresponding group of sample risk prediction coefficients, and divides these sample state health deviation analysis results and the corresponding sample risk prediction coefficients to obtain a training set and a validation set, and then uses random numbers to initialize the neural network framework, that is, assigning a small random value to the weight and bias. After that, the system terminal divides the training set into multiple small batches. In each iterative training, the system terminal inputs the data of the current small batch into the neural network, calculates it layer by layer through the network layer until it reaches the output layer, and calculates the risk prediction coefficient at the output layer, and then compares it with the sample risk prediction coefficient, and calculates the loss value through the mean square error. Then, the loss value is used to calculate the gradient of the network parameters, that is, the partial derivative of the loss value with respect to each parameter. This step involves the application of the chain rule to back-propagate the gradient from the output layer to the input layer. Then, the optimization algorithm SGD and the calculated gradient are used to update the network parameters to minimize the loss function, that is, adjust the parameters to make the prediction of the neural network on the training data more accurate. During the training process, in addition to using the training data to update the parameters of the neural network, the performance of the neural network is also evaluated on the validation set. If the performance of the neural network on the validation set does not improve significantly or decreases in multiple consecutive iterations, the training is stopped to avoid overfitting. After the training stops, the system terminal outputs the current neural network as a risk prediction model. Repeat the above training process, and use the remaining K-1 groups of sample state health deviation analysis results and K-1 groups of sample risk prediction coefficients to build K-1 risk prediction models. Finally, the system terminal connects the K risk prediction models in parallel to build the first component risk prediction channel.

Input the health deviation analysis results of the first component state into the K risk prediction models to obtain K risk prediction coefficients; perform proportion calculation according to the K risk prediction accuracy parameters corresponding to the K risk prediction models to obtain K risk prediction incentive coefficients; perform weighted calculation on the K risk prediction coefficients according to the K risk prediction incentive coefficients to obtain the first component state risk coefficient.

Optionally, after constructing the first component risk prediction channel, the system terminal inputs the first component state health deviation analysis result into the first component risk prediction channel, and the first component risk prediction channel generates K risk prediction coefficients based on the internal K risk prediction models. These coefficients represent the risk level that the first component risk prediction channel judges the component may have in the current state. Subsequently, the system terminal adds the risk prediction accuracy parameters of each model, and then uses the risk prediction accuracy parameters of each model and the summed result to calculate the proportion, and obtains the risk prediction incentive coefficient of each model. Among them, the risk prediction accuracy parameter of each model refers to the accuracy index obtained by testing the model using data that is not used for training and verification. Afterwards, the system terminal uses the calculated risk prediction incentive coefficient of each model as the weight of the model, multiplies it with the risk prediction coefficient corresponding to the model, and then sums the K products to obtain the first component state risk coefficient. This risk coefficient combines the prediction results of multiple models and reflects the overall risk level that the first component may face in the current state.

If the first component state risk coefficient is greater than/equal to a predetermined state risk coefficient, a first risk warning signal is generated, and an abnormal warning is issued to the high-speed laser film-making and slitting machine according to the first risk warning signal.

In one embodiment, if the calculated first component state risk coefficient is greater than or equal to the predetermined state risk coefficient, it means that the first component has hidden dangers or is in a high-risk state. At this time, the system terminal will immediately generate a first risk warning signal. The function of this signal is to issue a clear warning to the maintenance personnel, indicating that the first component of the high-speed laser filming and striping machine is currently in a high-risk state and may have hidden dangers of failure or performance degradation.

Furthermore, the present application provides an abnormal environment early warning, including:

According to the sensor monitoring network, the real-time working environment information corresponding to the high-speed laser film-making and slitting integrated machine is obtained; based on the predetermined working environment information of the equipment, the real-time working environment information is detected for abnormality to obtain abnormal working environment information; based on the abnormal working environment information, an abnormal level evaluation is performed to generate an abnormal environment level; based on the abnormal environment level, an abnormal environment warning is issued to the high-speed laser film-making and slitting integrated machine.

Preferably, during the operation of the high-speed laser film-making and striping machine, the system terminal obtains the working environment information of the device in real time through the sensor monitoring network deployed, including parameters such as temperature, humidity, and light intensity. This information is crucial to ensure the normal operation of the high-speed laser film-making and striping machine, because any abnormality of the environmental parameters may affect the performance and life of the high-speed laser film-making and striping machine. Subsequently, the system terminal compares the real-time acquired working environment information with the predetermined working environment information of the device. Through comparison and analysis, it is identified which environmental parameters have an absolute difference greater than or equal to the environmental deviation threshold with the predetermined environmental parameters, thereby determining the presence of abnormal working environment information. Once the abnormal working environment information is detected, the system terminal assigns a weight to each parameter according to the importance of the environmental parameters recorded in the abnormal working environment information, and then uses these weights to perform weighted summation on the absolute difference to obtain a comprehensive abnormal index. Afterwards, the position of this comprehensive abnormal index in the preset level interval is determined to generate the corresponding abnormal environment level. Among them, the preset level interval is set according to historical data, equipment specifications and safety standards. Then, based on this abnormal environment level, the system terminal will issue an abnormal environment warning to the maintenance personnel. The warning information will clearly indicate the specific situation, level and possible consequences of the current environmental abnormality, so that maintenance personnel can respond quickly and take necessary measures to adjust or improve the working environment to ensure the stable operation of the high-speed laser filming and slitting machine.

In summary, the embodiments of the present application have at least the following technical effects:

The embodiment of the present application first receives the working parameters and control scheme of the device, and obtains relevant working environment information. Based on this information, the various components of the device are analyzed and decomposed, and the control decision of each component is extracted. Subsequently, the health status of the component is predicted according to the working environment of the device and the control decision of the component, and a health status prediction matrix is generated. This matrix is used to judge the health status of each component. In the actual operation process, the working status of the device is monitored in real time using the sensor monitoring network. According to the real-time monitoring data and the health status prediction matrix, risk assessment is performed to generate the risk coefficient of the component. If the risk coefficient exceeds a predetermined threshold, an early warning signal is generated to indicate that the device may be abnormal. In order to generate the health status prediction matrix, relevant data is extracted from the historical monitoring records, and data cleaning and classification are performed. Then, the concentrated interval of the health status is identified through cluster analysis, and these results are integrated into the health status prediction matrix. In the registration and identification process, the health monitoring records are traversed, sample data is extracted and weighted analysis is performed, and a comprehensive registration coefficient is generated. If the registration coefficient meets the predetermined standard, these data are used for health status prediction. Afterwards, by collating and analyzing the real-time monitoring data, comparing it with the prediction matrix, evaluating the deviation, calculating the risk coefficient, and conducting risk prediction and early warning, the normal operation and maintenance of the equipment are ensured. These technical effects jointly solve the technical problem that the high-speed laser film-making and striping machine lacks effective means to monitor the working status of each component in real time and predict potential failure risks during its operation, resulting in untimely maintenance of the high-speed laser film-making and striping machine. It realizes the health status prediction and risk early warning of the key components of the high-speed laser film-making and striping machine, improves the stability and reliability of the operation of the high-speed laser film-making and striping machine, and reduces the failure downtime of the high-speed laser film-making and striping machine.
