extracting statistical features of the machine data, and generating a machine stabilizing function of the production machine according to the statistical features;
and generating the machine stability of the production machine by using the machine stability function.
In detail, the machine stability refers to the stability or reliability of the operating state of the production machine over a certain period of time; statistical features refer to statistics, such as mean, standard deviation, maximum, etc., used to describe a data set.
In detail, the statistical features of the machine data are extracted by cleaning the collected machine data to remove abnormal values and error information therein, thereby obtaining cleaning data. And classifying the cleaning data according to a certain characteristic attribute to obtain classified data. Finally, the classified data are converted into vector forms by using a vector conversion method, the statistical characteristics of the machine data are obtained, the running state and the performance index of the production machine can be known on the whole by extracting the statistical characteristics of the machine data, and a data basis is provided for the subsequent stability calculation.
In detail, by generating a machine stabilization function, machine data can be converted into a mathematical model to calculate the machine stability of the production machine.
Further, the generated machine stability function is used for calculating the machine stability of each production machine, namely, the machine stability is calculated according to the production record and the average value of the production machine, the stability and the reliability of the production machine can be evaluated through calculating the machine stability, potential problems are found and solved, and the production efficiency is improved.
In detail, the statistical features of the extracted machine data are:
performing data cleaning on the machine data to obtain cleaning data of the machine data;
performing data classification on the cleaning data to obtain classification data of the cleaning data;
and carrying out vector transformation on the classified data to obtain a transformation vector of the classified data, and generating statistical characteristics of the machine data by using the transformation vector.
In detail, the data cleaning refers to processing data, and removing interference factors such as abnormal values, missing values, repeated values, inconsistent values and the like in the data to obtain more standardized and more accurate data, wherein the data cleaning is one of important links of data preprocessing; data classification refers to the process of grouping data according to certain attributes or rules. By classifying the data, the organization and management of the data can be realized, and the internal rule among the data can be better found; vector transformation is the process of converting data from an original form into vectors. Representing the data set with vectors not only improves the efficiency of data processing, but also better describes the similarity and difference between the data.
In detail, the purpose of data cleaning is to remove interference factors and improve data quality and accuracy. Data cleansing is typically accomplished by the following steps: removing abnormal values: unreasonable, extreme or outlier data is eliminated, so that the data is more real and effective; filling up missing values: for the data with missing information, filling the missing values by adopting methods such as mean value, median and the like, so as to ensure the data integrity; and (5) de-duplication: if repeated records exist in the data, the repeated data need to be deleted, and the data redundancy is avoided; format conversion: and converting the data which does not meet the data format requirement into a correct format, and avoiding subsequent processing errors. For example, in factory machine data, there may be sensor damage or reading errors, etc., and these problems can be eliminated by data cleaning, ensuring the accuracy and authenticity of the machine data.
In detail, by classifying machine data, the data can be better organized and managed, and intrinsic laws between the data can be more effectively discovered. The specific implementation mode of data classification is as follows: classifying according to the attribute: data is divided into categories according to a certain attribute. For example, machine data is classified into two types of high and low temperature according to temperature size; classifying according to rules: the data are classified into different categories according to a rule set in advance. For example, machines whose machine yield is lower than a certain value for a certain period of time are classified as abnormal machines or damaged machines, or the like. For example, in factory machine data, machines may be categorized according to attributes such as production time, model, operating status, etc., to facilitate subsequent analysis.
In detail, the machine data is transformed into a vector form by means of vector transformation in order to better describe its statistical characteristics. The specific implementation mode is as follows: word bag model: representing each word in the text data as a vector, using the number of occurrences of each word in the text as a value for the corresponding position in the word vector; TF-IDF model: representing words in the text data as a vector, and multiplying the frequency of each word in the text by the frequency of the word in all the texts as a value of the corresponding position in the word vector; one-hot encoding: each discrete attribute value is represented as a vector in which the corresponding attribute value is 1 in position and 0 in other positions. For example, in plant machine data, various data information collected by the machine may be converted into a vector form, e.g., current and temperature may be converted into a two-dimensional vector, where the two components represent the values of current and temperature, respectively. In this way, various statistical features in the vector may be used to describe the machine's operating state and performance metrics.
Further, assuming multiple machines in a plant, each machine collects different data information including machine run time, current, temperature, etc. First, machine data is subjected to data cleaning and sorting, for example, operations of removing outliers, filling missing values, sorting by model, and the like. The classified machine data is then converted into a vector form, e.g., machine run time and current are converted into a two-dimensional vector, where the first component represents machine run time and the second component represents machine current. Through the statistical characteristics in the vector, performance indexes such as average running time, current variance and the like of each machine can be obtained, and the machine stability of each machine can be calculated according to the performance indexes. Through calculation and analysis of the machine stability, the reliability and stability of each machine can be evaluated.
In detail, the machine stabilization function comprises:
wherein,is->-machine stability of the production machine, < >>Is->Each of the production machines is atAverage production value in each cycle, +.>Is the total number of observation periods, +.>Is->The production machine is in observation period +.>Second production record,/->Is->The production machine is->Actual production quantity in cycle, +.>Is a machine identification of the production machine.
In detail, the machine stabilization function represents, for each machineFirst, calculate its average production value +.>Then, for each observation period, +.>The actual production quantity of the bench machine in the cycle +.>Next, the difference between the actual production quantity and the average production value of the machine in the observation period is calculated>For each observation period, the square of the difference is +.>Summing to obtain a sum of squares of the differences over the observation period, and finally dividing the sum of squares of the differences over the observation period by +.>Obtaining the machine stability of the machine>。
In detail, the machine stabilization function means by comparing the difference between the actual production quantity and the average production value in each observation periodTo evaluate the stability of the machine. If the number of machines produced is close to the average value per cycle, the sum of squares of the differences is small, and the machine stability is low Will be higher; conversely, if the production quantity of the machine fluctuates greatly, the sum of squares of the differences will be large, the machine stability +.>Will be lower.

acquiring production time data of a factory product in the target factory, defect product data corresponding to the factory product, qualified product data corresponding to the factory product and worker data corresponding to the factory product;
and collecting the production time data, the defective product data, the qualified product data and the worker data as product data of the target factory.
In detail, the product data includes information such as production time data of the factory product, defect product data, qualified product data, worker data, etc., wherein the production time data refers to the time spent by the factory product in the production process, and can be used for comparing the production efficiency between different products; defective product data refers to the number and type of products detected to have defects during the production process, and can be used to evaluate the quality level of the factory product; the qualified product data refers to the quantity and the category of products which are detected to meet the requirements in the production process, and can be used for evaluating the production efficiency and the quality level of factory products; worker data refers to worker information involved in the production of a factory product, including the number of workers, skill level, etc.
In detail, the relevant data is collected, consolidated and processed in the target plant by using a computer or other corresponding technical means, resulting in a complete product data set.
