Description
Technical Field
[0001] The invention relates to the technical field of application data interaction, and in particular to an application data interaction method based on cloud manufacturing collaboration. Background Art
[0002] Cloud manufacturing collaboration aims to integrate manufacturing resources distributed in different geographical locations and organizations to achieve efficient collaborative production. The application data interaction method is a key link, which ensures the accurate, timely and effective flow of data throughout the collaborative process. In the field of cloud manufacturing collaboration, the existing application data interaction methods are diverse, but there are many shortcomings. Common data preprocessing methods are usually simple data cleaning and basic standardization operations. Data reading relies on traditional methods and has limited ability to process unstructured data. Data mining mostly uses traditional algorithms, which are unable to cope with complex large-scale data and mine deep associations. System analysis mainly relies on simple statistical analysis and chart display, which makes it difficult to deeply analyze system uncertainty. The existing interaction methods are selected because their technology is relatively mature and stable with low risk; second, the cost is relatively low, which meets the resource constraints of enterprises; third, the technical personnel are familiar with it, the operation threshold is low, and it is easy to promote.
[0003] However, existing methods have obvious problems. Data preprocessing is difficult to effectively remove complex noise and abnormal data, which affects the accuracy of subsequent analysis. Data reading cannot fully handle multiple data types, which limits data utilization. Data mining is not deep enough, making it difficult to discover complex associations and patterns. The value of data is not fully mined, and system analysis is not comprehensive and accurate, which cannot effectively support decision-making. In addition, the overall efficiency and performance are low, and the speed of processing large-scale data is slow, making it difficult to meet real-time requirements.
[0004] The application scenarios of cloud manufacturing collaboration are characterized by wide data sources, complex collaboration needs, high uncertainty and high real-time requirements. Existing data interaction methods are difficult to cope with these complex scenarios and cannot meet the growing needs. Summary of the invention
[0005] The present invention provides an application data interaction method based on cloud manufacturing collaboration, which improves the data quality of the cloud manufacturing system, removes noise and abnormal data and standardizes the data format; realizes efficient and accurate reading and integration of multiple data types, breaks down data type barriers, enhances the depth and accuracy of data mining, and discovers complex data relationships and patterns; deeply analyzes the uncertainty of the cloud manufacturing system, and provides intuitive, clear and powerful data support and decision-making basis for collaborative work.
[0006] In order to solve the above problems, the technical solution adopted by the invention is:
[0007] An application data interaction method based on cloud manufacturing collaboration, characterized by comprising the following steps:
[0008] S1 data preprocessing step, deeply processes the data output by the cloud manufacturing system, removes noise and abnormal data, and standardizes and normalizes the data to obtain high-quality ideal data for system uncertainty analysis;
[0009] S2 data reading step, which efficiently and accurately reads various data types of files that are imported or newly created after preprocessing, including but not limited to structured, semi-structured and unstructured data;
[0010] S3 data mining step, which displays the read pre-processed data in the form of a multi-dimensional matrix, accurately screens out concept pairs with strong correlation by calculating the conditional entropy and relative mutual information between concepts, and deeply mines the complex effective association rules and accurately determines the corresponding fine sub-patterns for information-dominated concept pairs based on the strictly preset high confidence and high support, and then integrates the information entropy of the sub-patterns in each information-dominated concept pair;
[0011] In the S4 system analysis step, a comprehensive and accurate cloud manufacturing system information association cognitive map is constructed based on the above mining results, the uncertainty of the cloud manufacturing system is deeply analyzed, and the analysis results are displayed and output in an intuitive and clear manner, providing strong data support and decision-making basis for cloud manufacturing collaboration.
[0012] The beneficial effects of this program are:
[0013] Beneficial effects:
[0014] By deeply preprocessing the output data of the cloud manufacturing system, removing noise and abnormal data and standardizing and normalizing it, high-quality ideal data is provided for subsequent analysis. At the same time, multi-dimensional matrix system analysis technology constructs an information association cognitive map, which can accurately mine the association rules and hidden patterns in the data, and deeply analyze the system uncertainty, so that decision makers can make wise decisions based on more accurate, comprehensive and in-depth information, reduce decision-making errors and improve decision accuracy.
[0015] It has the ability to efficiently and accurately read files of various data types, including structured, semi-structured and unstructured data, breaking the limitations of data types and ensuring the integrity and comprehensiveness of data. This helps to have a more comprehensive understanding of the system status, reasonably allocate manufacturing resources, and reduce collaboration barriers caused by data incompatibility and poor circulation, thereby improving the collaborative efficiency of the cloud manufacturing system and reducing production costs.
[0016] Advanced data mining technology can discover complex effective association rules and potential innovation patterns, providing new ideas and directions for the development and optimization of cloud manufacturing collaboration models. Comprehensive and in-depth system analysis helps stimulate innovative thinking, enhance innovation capabilities, and promote continuous progress in the field of cloud manufacturing. During the entire data interaction process, data compression, encryption and other processing measures are taken to ensure data security and privacy, reduce the risk of data leakage, and provide a reliable environment for the stable operation of cloud manufacturing collaboration.
[0017] Furthermore, the S1 adopts a convolutional neural network algorithm based on deep learning. By learning a large number of noise and abnormal data samples, it can accurately identify and remove noise and outliers in the data. At the same time, it uses an automatic encoder to reconstruct the data, accurately remove noise and outliers, and reconstruct the data, which significantly improves the accuracy and completeness of the data, and provides a more reliable and high-quality data foundation for subsequent analysis and decision-making. The processed data is purer, making the models trained based on these data or the analysis conducted more robust and able to better cope with various complex situations and interferences.
[0018] Furthermore, the S2 utilizes lexical analysis, syntactic analysis, and semantic understanding algorithms in natural language processing technology to deeply analyze the text content in unstructured data, extract key information, and convert it into a structured or semi-structured data format, converting unstructured text data into a structured or semi-structured format to facilitate integration and unified processing with other types of data, thereby improving the efficiency of data management. Through the comprehensive use of lexical analysis, syntactic analysis, and semantic understanding algorithms, key information can be extracted more accurately, information omissions and errors can be reduced, and unstructured text data that was originally difficult to process and utilize becomes easy to analyze and use, thereby expanding the scope of data availability.
[0019] Furthermore, the S3 introduces an optimization mechanism based on an evolutionary algorithm, which dynamically adjusts the preset values of confidence and support by simulating the inheritance, mutation and selection operations in the biological evolution process, and continuously optimizes these two parameters according to the distribution characteristics of the data and the mining objectives. By optimizing the confidence and support according to the data distribution characteristics and the mining objectives, it is possible to more accurately mine truly valuable association rules, reduce misjudgments and omissions, and dynamically adjust parameters so that the data mining process can adapt to the ever-changing data situation and maintain a good mining effect, rather than relying on fixed preset values, thereby avoiding invalid mining or over-mining caused by unreasonable initial preset values, saving computing resources and time, and improving overall mining efficiency.
[0020] Furthermore, the S4 uses visual analysis tools to present the analysis results in the form of charts, graphs and interactive dashboards. Through data visualization layout design, color coding and animation effects, the intuitiveness and readability of the analysis results are enhanced. Complex data and analysis results are presented in the form of charts, graphs, etc., and abstract data is converted into intuitive visual elements, so that users can see the main trends and key features of the data at a glance. Users can quickly grasp key information and quickly understand the meaning behind the data, so as to make more informed decisions in a short period of time, which is especially advantageous when time is tight.
[0021] Furthermore, S1 also includes compressing the data, using a lossless compression algorithm to reduce data storage space, and at the same time, encrypting the data using an advanced encryption standard encryption algorithm. The use of a lossless compression algorithm can significantly reduce the storage space occupied by the data and reduce storage costs, especially for large-scale cloud manufacturing data, which can save a lot of hardware resources. Using an advanced encryption standard encryption algorithm to encrypt the data keeps the data in an encrypted state during storage and transmission, making it difficult to decipher even if it is illegally obtained, thereby effectively preventing data leakage and unauthorized access.
[0022] Furthermore, the S3 adopts a distributed computing framework to decompose large-scale data processing tasks into multiple computing nodes for parallel execution. Through data partitioning, task scheduling and fault-tolerant mechanisms, it fully utilizes computing resources and significantly accelerates the data mining process. Large-scale data processing tasks are parallelized, and multiple computing nodes work simultaneously, which greatly shortens the data mining time and enables rapid acquisition of analysis results. The fault-tolerant mechanism ensures that when some computing nodes fail, the tasks can continue to be executed and the entire data mining process will not be interrupted due to failures of individual nodes.
[0023] Furthermore, the S4 combines discrete event simulation with simulation technology to simulate and verify the uncertainty of the cloud manufacturing system multiple times. By adjusting the input parameters and model structure, the system performance is optimized. Through multiple simulations and verifications of uncertainty, potential risks can be assessed in advance, possible problems can be predicted, and a basis can be provided for enterprises to formulate response strategies. The input parameters and model structure can be adjusted based on the simulation results to help decision makers find the best solutions and strategies before actual operations, thereby improving the scientificity and accuracy of decision-making. Simulation and verification are performed in a virtual environment to avoid the high costs and potential losses that may be caused by conducting experiments in actual systems.
[0024] Furthermore, the S2 adopts data caching technology to store frequently accessed data in high-speed memory. By optimizing the cache strategy and setting an appropriate cache expiration time and update mechanism, the speed and efficiency of data reading are improved. Storing frequently accessed data in high-speed memory can significantly reduce the time for data reading, achieve fast response, improve user experience, reduce frequent access to the back-end storage system, and reduce I / O operations, thereby reducing the overall burden of the system and improving system stability.
[0025] Furthermore, the S4 establishes a prediction model based on the historical data analysis results using a time series prediction algorithm or an LSTM neural network. The model can consider factors such as seasonality, trend, and periodicity to predict future system status and performance. Based on the prediction of future system status and performance, enterprises can formulate strategies and plans in advance and make forward-looking decisions. BRIEF DESCRIPTION OF THE DRAWINGS
[0026] Figure 1 It is a flow chart of the principle of the present invention; DETAILED DESCRIPTION
[0027] The following is further described in detail through specific implementation methods:
[0028] Example 1
[0029] First, the data output by the cloud manufacturing system is collected, and a convolutional neural network algorithm based on deep learning is used to train the algorithm in advance using a large amount of sample data containing noise and outliers. When actually processing the data, the algorithm can quickly and accurately identify the noise and outliers in the current data and remove them. At the same time, the automatic encoder is used to reconstruct the processed data to further ensure the accuracy and completeness of the data.
[0030] After completing the above operations, the data is standardized and normalized. The Z-score standardization method is used to convert the data into a distribution with a mean of 0 and a standard deviation of 1. Then, Min-Max normalization is used to map the data to a specific interval.
[0031] The reason for doing this is that deep learning algorithms can learn complex data patterns, thereby removing noise and outliers more accurately, while standardization and normalization help eliminate the impact of data dimensions, making data with different characteristics comparable, providing a high-quality foundation for subsequent analysis, improving the accuracy and reliability of subsequent data processing and analysis, enhancing the robustness of the model, and reducing the error rate.
[0032] In the data reading stage, when the imported or newly created data file is received after preprocessing, it is processed using the lexical analysis, syntactic analysis and semantic understanding algorithms in natural language processing technology. For unstructured text data, lexical analysis is first performed to divide the text into basic elements such as words and punctuation marks. Then, the structure and grammatical relationship of the sentence are determined through syntactic analysis. Finally, the semantic understanding algorithm is used to extract key information.
[0033] Convert the extracted key information into a structured or semi-structured data format, convert the product specification information described in the text into a table, or convert user comments into key-value pairs. The reason for adopting this approach is that natural language processing technology can deeply understand the meaning of the text, accurately extract key information, and convert unstructured data into a structured or semi-structured format to facilitate subsequent storage, query and analysis, improve the efficiency of data management, reduce information omissions and errors, expand the available scope of data, and promote the integration and unified processing of different types of data.
[0034] The read preprocessed data is presented in the form of a multidimensional matrix, and the conditional entropy and relative mutual information between concepts are calculated to screen out concept pairs with strong correlation. For information-dominated concept pairs, an optimization mechanism based on evolutionary algorithms is introduced according to strict high confidence and high support thresholds set in advance. In the evolutionary algorithm, the inheritance, mutation and selection operations of biological evolution are simulated. According to the distribution characteristics of the data and the mining objectives, the preset values of confidence and support are dynamically adjusted, and these two parameters are continuously optimized to mine complex and effective association rules and determine the corresponding fine sub-patterns. Then, the information entropy of the sub-patterns in each information-dominated concept pair is integrated. Because the evolutionary algorithm can adaptively optimize parameters, it can better adapt to the characteristics of the data and mining needs, more accurately mine valuable association rules, reduce misjudgments and omissions, improve mining efficiency, avoid invalid or excessive mining, and save computing resources and time.
[0035] Based on the results of data mining, a comprehensive and accurate cognitive map of cloud manufacturing system information association is constructed. Visual analysis tools such as PowerBI or Tableau are used to present the analysis results in the form of charts, graphs and interactive dashboards. The intuitiveness and readability of the analysis results are enhanced through carefully designed layouts, color coding and animation effects.
[0036] At the same time, combined with simulation technology and discrete event simulation, the uncertainty of the cloud manufacturing system is simulated and verified multiple times. Based on the results of historical data analysis, a prediction model is established using time series prediction algorithm or LSTM neural network. This model fully considers factors such as seasonality, trend and periodicity, and predicts the future system status and performance. Visual analysis tools can intuitively present complex data relationships, simulation technology can assess risks and optimize systems in advance, and time series prediction algorithms can provide a basis for future decision-making, helping users quickly understand and gain insight into system uncertainties, optimize system performance, formulate strategies and plans in advance, make forward-looking decisions, and improve the efficiency and effectiveness of cloud manufacturing collaboration.
[0037] In addition, in S1, data is compressed and encrypted, the LZ77 algorithm is used to reduce data storage space, and the Advanced Encryption Standard (AES) algorithm is used to encrypt data to ensure data security.
[0038] In the data mining step, the distributed computing framework Hadoop or Spark is used to decompose large-scale data processing tasks into multiple computing nodes for parallel execution. Through data partitioning, task scheduling and fault-tolerant mechanisms, computing resources are fully utilized to accelerate the data mining process.
[0039] In the data reading step, Redis cache is used to store frequently accessed data in high-speed memory. By optimizing the cache strategy and setting appropriate cache expiration time and update mechanism, the speed and efficiency of data reading are improved.

These samples should cover various possible data patterns and abnormal situations.
