Description

Data Analysis-Based Coarse and Fine Coal Slurry Classification Report Generation System Technical Field

[0001] This invention relates to the field of coarse and fine coal slime classification technology, specifically a coarse and fine coal slime classification report generation system based on data analysis. Background Technology

[0002] A coarse and fine coal slime grading report refers to the process of determining and analyzing the physical and chemical properties of coarse and fine coal slime, obtaining the grading results, and compiling the results into a report. This report typically includes the basic properties of the coal slime, the content of major chemical elements, ash content, volatile matter, fixed carbon, moisture, and other indicators, as well as the results of classifying the coal slime into different grades according to certain standards.

[0003] The existing coarse and fine coal slime grading report generation system relies on manual data input, which is prone to errors and slows down processing. This significantly prolongs report generation time and reduces work efficiency. Incorrect coal slime data can lead to the classification of actual coarse and fine coal slime samples as one grade lower or higher than their actual grade. Since lower-grade coarse and fine coal slime is usually cheaper than higher-grade, classifying actual high-grade coarse and fine coal slime as low-grade can increase production costs. The grade of coarse and fine coal slime determines its calorific value and other physicochemical properties; using lower-grade coarse and fine coal slime during production can affect the quality of the final product. Furthermore, when a certain indicator in the coarse and fine coal slime grading report fluctuates, staff need to manually search the repository for related grading reports for reference, which is time-consuming and labor-intensive.

[0004] To address the aforementioned shortcomings, a data analysis-based system for generating coarse and fine coal slime classification reports is provided. Summary of the Invention

[0005] The purpose of this invention is to solve the problems of inaccurate and rapid classification of coarse and fine coal slime and the inability to find specific previous coarse and fine coal slime classification reports related to abnormal fluctuations when such reports show abnormal fluctuations. Therefore, this invention proposes a coarse and fine coal slime classification report generation system based on data analysis.

[0006] The objective of this invention can be achieved through the following technical solution: a data analysis-based coarse and fine coal slime grading report generation system, including a server; and also including an information query terminal, a data acquisition and detection terminal, and a sampling and sample preparation terminal connected to the server;

[0007] The data acquisition and detection terminal compares and analyzes the detected values ​​of coarse and fine coal slime with the coarse and fine standard content group to obtain the coal slime classification, detected value and grade value, and marks them as a report group to be sent to the server for storage;

[0008] The sampling and preparation end labels the coarse and fine coal slime to obtain the coarse and fine coal slime label and sends it to the server for storage. At the same time, the sampling and preparation speed is adjusted according to the feedback signal from the server. After adjustment, a repeat verification command is sent to the server to obtain the coarse and fine coal grade value and perform numerical analysis to obtain the grade change value. When the grade change value is greater than the preset change value, the adjustment is recorded as valid; otherwise, it is recorded as invalid and a coarse and fine coal slime separation process adjustment signal is generated and sent to the server for display.

[0009] When the server receives Report Component 1, it extracts the number of samplings and the coal slime detection value from the previous sampling from Report Component 1, calculates the difference to obtain the parameter value, and performs numerical dispersion analysis on the parameter value to determine whether the coal slime parameter value is stable or fluctuating, the corresponding parameter value and fluctuation time, and marks it as Report Component 2.

[0010] The information query terminal receives the user's input time node and retrieves Report Component 1 and Report Component 2 corresponding to the sampling time closest to the time node from the server. Report Component 1 and Report Component 2 corresponding to the sampling time are marked as analysis reports. When the coal slime parameters in the analysis report are stable, the analysis report is marked as a coal slime grading report and displayed. When the coal slime parameters in the analysis report fluctuate, all coal slime grading reports that overlap with the parameters in the fluctuations of the coal slime parameters in the analysis report are retrieved and marked as comparison reports. The number of overlapping fluctuating parameter values ​​is retrieved, and the difference between the fluctuating overlapping parameter values ​​and the parameter values ​​in the analysis report is calculated to obtain the overlap value. The time difference between the sampling time of the analysis report and the sampling time of the comparison report is calculated to obtain the duration value.

[0011] The number of overlaps (HS), overlap value (HC), and duration value (SC) are calculated using a preset formula. The similarity value XSZ is obtained, where d1, d2, and d3 are preset weight coefficients, and γ is a preset correction coefficient. All comparison reports are sorted from largest to smallest according to their similarity values. The sampling time and the corresponding coarse and fine coal slime separation process parameters of the comparison reports are retrieved and marked as report group three. Report group one, report group two, and report group three are marked as coal slime grading reports and displayed and sent to the server for storage.

[0012] In a preferred embodiment of the present invention, the coal slime grading includes superior grade one coarse coal slime, qualified coarse coal slime, subgrade one coarse coal slime, superior grade one clean coal slime, qualified clean coal slime, and subgrade one clean coal slime; the test values ​​include coal slime moisture content, ash content, volatile matter content, and fixed carbon content; the coarse standard content group includes coarse standard moisture range, coarse standard ash range, coarse standard volatile matter range, and coarse standard fixed carbon range, and the fine standard content group includes fine standard moisture range, fine standard ash range, fine standard volatile matter range, and fine standard fixed carbon range.

[0013] As a preferred embodiment of the present invention, the specific steps for generating a report composition are as follows:

[0014] The detection values ​​of coarse and fine coal slime were compared and analyzed with the standard content group of coarse and fine coal slime to obtain the moisture correlation value, ash correlation value, volatile matter correlation value and fixed carbon correlation value of coarse and fine coal slime. The four values ​​were normalized to obtain the grade value of coarse and fine coal slime. The grade value of coarse and fine coal slime was compared and analyzed with the grade range of coarse and fine coal slime to obtain the classification of coarse and fine coal slime. The coal slime grade, detection value, classification and grade value were marked as a report component.

[0015] As a preferred embodiment of the present invention, the specific steps for generating report component two are as follows:

[0016] The differences between the moisture content, ash content, volatile matter content, and fixed carbon content of coal slime and the results from the previous sampling time are calculated to obtain the corresponding differences in moisture content, ash content, volatile matter content, and fixed carbon content. These differences are then labeled as parameter values. All parameter values ​​for the current day are retrieved and plotted as points on a two-dimensional rectangular coordinate system to obtain a trend chart of parameter values ​​for coarse and fine coal slime on that day. The differences between parameter values ​​from adjacent time periods are calculated to obtain the parameter differences. The variance of the parameter difference is calculated. When the variance of the parameter difference is greater than the preset variance value, it indicates that the parameter difference is unstable, and a parameter value fluctuation signal is output. The parameter value fluctuation signal includes the fluctuation signals of coal slime moisture content, ash content, volatile matter content, and fixed carbon content. When the variance of the parameter difference is less than or equal to the preset variance value, it indicates that the parameter difference does not fluctuate significantly, and a parameter value stability signal is output. The parameter value stability signal includes the stability signals of coal slime moisture content, ash content, volatile matter content, and fixed carbon content.

[0017] When the output is a parameter value fluctuation signal, a preset threshold is used. When the parameter value exceeds the preset threshold, the two time points corresponding to the parameter value are retrieved, and the time period corresponding to these two time points is marked as the fluctuation period. Specifically, when the output is a coal slime moisture difference fluctuation signal, a preset moisture threshold is used. When the coal slime moisture difference exceeds the preset coal slime moisture threshold, it indicates that the coal slime moisture difference is fluctuating greatly. Therefore, the two time points corresponding to the coal slime moisture difference are retrieved, and the time period corresponding to these two time points is marked as the fluctuation period.

[0018] The report consists of two parts: one where the coal slime parameter values ​​are stable or fluctuate, along with the corresponding parameter values ​​and the time period of the fluctuation.

[0019] As a preferred embodiment of the present invention, the specific steps for adjusting the sampling and sample preparation end are as follows:

[0020] Coarse and fine coal slime samples were collected and prepared from the outlets of coarse and fine coal slime to obtain coarse and fine coal slime samples, respectively. These samples were then labeled, with the labeling composition for the coarse coal slime being: C i +Date+Sampling Time+Sampling Time; The grade composition of the refined coal slime is J i +Date+Sampling Time+Sample Preparation Time, where i = 1, 2, 3...n1, n1 is a positive integer, and n1 represents the total number of sampling and sample preparations on that day;

[0021] Upon receiving a feedback signal from the server, the current sampling and sample preparation times are retrieved. The time difference between the sampling and sample preparation times is calculated to obtain the sampling and preparation duration, which is then denoted as Q. i The specific analysis of the sampling and preparation time is as follows:

[0022] Obtain the current sampling duration and apply it to the preset model. The sampled value QZY was obtained. i Where σ is a preset correction coefficient, when the sample value QZY is taken. i If the sampling time is less than the preset sampling value, it indicates that the current sampling time exceeds the specified time. This may be due to changes in the coal slime caused by the long sampling time, leading to inaccurate test results. In this case, output i and simultaneously control the speed of the sampling robotic arm to increase by one level. After adjustment, generate a repeat verification command and send it to the server to obtain the grade values ​​of coarse and fine coal slime from the i+n2 samplings and the grade values ​​of coarse and fine coal slime from the i-th sampling. Then, use the coarse grade value cdz from the i+n2 samplings. i+n2 And the quality level value CDZ i+n2 coarse grade value cdz of the ith order i And the quality level value CDZ i By preset formula The grade change value DJB is obtained, where f1 and f2 are preset weight coefficients, η is a preset correction coefficient, and n2 is a positive integer. When the grade change value is greater than the preset change value, an effective adjustment signal is output and an effective adjustment is recorded. Otherwise, an invalid adjustment signal is output and an invalid adjustment is recorded. A coarse and fine coal slime separation process adjustment signal is generated and sent to the server for display.

[0023] In a preferred embodiment of the present invention, when a repeat verification instruction is received, the grade values ​​of the coarse and fine coal slime samples taken in the (i+n2)th time and the grade values ​​of the coarse and fine coal slime samples taken in the (i)th time are retrieved. The coarse and fine grade values ​​from the (i+n2)th time and the coarse and fine grade values ​​from the (i)th time are processed to obtain a grade change value. When the grade change value is greater than a preset change value, an adjustment valid signal is output and an adjustment valid is recorded; otherwise, an adjustment invalid signal is output and an adjustment invalid is recorded. A coarse and fine coal slime separation process adjustment signal is generated and sent to the server for display.

[0024] Compared with the prior art, the beneficial effects of the present invention are:

[0025] 1. By comparing the test values ​​of coarse and fine coal slime with the standard content group of coarse and fine coal slime, the moisture, ash, volatile matter and fixed carbon correlation values ​​of coarse and fine coal slime are obtained. The four values ​​are normalized to obtain the coarse and fine grade value, and the grade of coarse and fine coal slime is determined accordingly. This enables rapid and accurate grading of coarse and fine coal slime. The coal slime number, test value, grade and grade value are marked as a report.

[0026] 2. When the coarse and fine coal slime is downgraded, the sampling time in the coal slime detection is analyzed to obtain the sampling value. Based on this, it is determined whether to accelerate the speed of the sampling robotic arm. The grade values ​​of the coarse and fine coal slime before and after the adjustment are analyzed and numerically processed to obtain the grade change value. At the same time, the grade change value is used to determine whether the current adjustment is effective. If it is ineffective, a coarse and fine coal slime sorting process adjustment signal is generated and sent to the server for display. This eliminates the possibility that the coal slime changes due to the long sampling time, which may lead to inaccurate detection results, thus making the coarse and fine coal slime detection values ​​more accurate.

[0027] 3. By analyzing coal slime parameter values, the degree and duration of fluctuations in these values ​​are determined, resulting in stable or fluctuating coal slime parameter values, corresponding parameter values, and fluctuation time periods. These are then marked as Report Group Two. Simultaneously, based on the time node of the information query terminal, the sampling time closest to the time node is retrieved, along with its corresponding Report Group One and Report Group Two. Analysis of Report Group One and Report Group Two reveals similar fluctuations in previous coal slime grading reports, and the corresponding coarse and fine coal slime separation process parameters are retrieved. Similar previous coal slime grading reports and their corresponding coarse and fine coal slime separation process parameters are marked as Report Group Three. Report Group One, Report Group Two, and Report Group Three are marked as the Coal Slime Grading Report. This clearly displays the coal slime grading status at any given time node, the fluctuation state of coal slime parameter values, and the specific fluctuation-related past coarse and fine coal slime separation process parameters, reducing the tedious steps of frequent data collection and analysis of coal slime separation processes similar to the current fluctuations for the queryer. Attached Figure Description

[0028] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to the accompanying drawings.

[0029] Figure 1 is a system block diagram of the present invention. Detailed Implementation

[0030] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Please refer to Figure 1, which shows the data analysis-based coarse and fine coal slime grading report generation system, which includes a server, a sampling and preparation terminal, a data acquisition and detection terminal, and an information query terminal connected to the server.

[0032] Coarse and fine coal slime samples were collected and prepared from the outlets of coarse and fine coal slime to obtain coarse and fine coal slime samples, respectively. These samples were then labeled, with the labeling composition for the coarse coal slime being: C i +Date+Sampling Time+Sampling Time; The grade composition of the refined coal slime is J i +Date+Sampling Time+Sample Preparation Time, where i = 1, 2, 3...n1, n1 is a positive integer, and n1 represents the total number of sampling and sample preparations on that day;

[0033] Upon receiving a feedback signal from the server, the current sampling and sample preparation times are retrieved. The time difference between the sampling and sample preparation times is calculated to obtain the sampling and preparation duration, which is then denoted as Q. i The specific analysis of the sampling and preparation time is as follows:

[0034] Obtain the current sampling duration and apply it to the preset model. The sampled value QZY was obtained. i Where σ is a preset correction coefficient, when the sample value QZY is taken. i If the sampling time is less than the preset sampling value, it indicates that the current sampling time exceeds the specified time. This may be due to changes in the coal slime caused by the long sampling time, leading to inaccurate test results. In this case, output 'i' and simultaneously increase the speed of the robotic arm for sampling by one level. After adjustment, generate a repeat verification command and send it to the server to obtain the grade values ​​of coarse and fine coal slime from the (i+5)th sampling and the grade values ​​of coarse and fine coal slime from the (i)th sampling. The coarse grade value (cdz) from the (i+5)th sampling is then used. i+5 And the quality level value CDZ i+5 coarse grade value cdz of the ith order i And the quality level value CDZ i The preset formula DJB=η×[f1×(cdz) is used. i+5 -cdz i )+f2×(CDZ i+5 -CDZ iThe grade change value DJB is obtained, where f1 and f2 are preset weight coefficients, and η is a preset correction coefficient. When the grade change value is greater than the preset change value, an effective adjustment signal is output and an effective adjustment is recorded. Otherwise, an invalid adjustment signal is output and an invalid adjustment is recorded. A coarse and fine coal slime separation process adjustment signal is generated and sent to the server for display. The sampling value is obtained by analyzing the sampling time in the coal slime detection, and it is determined whether to accelerate the speed of the sampling robotic arm. The grade values ​​of coarse and fine coal slime before and after the adjustment are analyzed and numerically processed to obtain the grade change value. At the same time, the grade change value is used to determine whether the current adjustment is effective. If it is ineffective, a coarse and fine coal slime separation process adjustment signal is generated and sent to the server for display. This eliminates the situation where the coal slime changes due to the long sampling time, resulting in inaccurate detection results, and makes the coarse and fine coal slime detection value more accurate.

[0055] The system presets a fineness grade range. When the fineness grade value falls within this range, it indicates that the overall fine coal slime meets the requirements of coarse fine coal slime, and a qualified fine coal slime signal and fineness grade value are output. When the fineness grade value is less than the maximum value in the preset fineness grade range, the fine coal slime is downgraded to coarse coal slime, and a fineness grade value is output.

The coal slime classification includes Grade 1 excellent coarse coal slime, qualified coarse coal slime, Grade 1 inferior coarse coal slime, Grade 1 excellent fine coal slime, qualified fine coal slime and Grade 1 inferior fine coal slime.

[0057] The differences between the moisture content, ash content, volatile matter content, and fixed carbon content of coal slime and the results from the previous sampling time are calculated to obtain the corresponding differences in moisture content, ash content, volatile matter content, and fixed carbon content. These differences are then labeled as parameter values. All parameter values ​​for the current day are retrieved and plotted as points on a two-dimensional rectangular coordinate system to obtain a trend chart of parameter values ​​for coarse and fine coal slime on that day. The differences between parameter values ​​from adjacent time periods are calculated to obtain the parameter differences. The variance of the parameter difference is calculated. When the variance of the parameter difference is greater than the preset variance value, it indicates that the parameter difference is unstable, and a parameter value fluctuation signal is output. The parameter value fluctuation signal includes the fluctuation signals of coal slime moisture content, ash content, volatile matter content, and fixed carbon content. When the variance of the parameter difference is less than or equal to the preset variance value, it indicates that the parameter difference does not fluctuate significantly, and a parameter value stability signal is output. The parameter value stability signal includes the stability signals of coal slime moisture content, ash content, volatile matter content, and fixed carbon content.

[0058] When the output is a parameter value fluctuation signal, a preset threshold is used. When the parameter value exceeds the preset threshold, the two time points corresponding to the parameter value are retrieved, and the time period corresponding to these two time points is marked as the fluctuation period. Specifically, when the output is a coal slime moisture difference fluctuation signal, a preset moisture threshold is used. When the coal slime moisture difference exceeds the preset coal slime moisture threshold, it indicates that the coal slime moisture difference is fluctuating greatly. Therefore, the two time points corresponding to the coal slime moisture difference are retrieved, and the time period corresponding to these two time points is marked as the fluctuation period.

[0059] The report will be divided into two parts, which will include whether the coal slime parameter values ​​are stable or fluctuating, the corresponding parameter values ​​and the time period of fluctuation.

[0060] The information query terminal receives the time node input by the user, retrieves Report Component 1 and Report Component 2 corresponding to the sampling time closest to the time node from the server, and marks Report Component 1 and Report Component 2 corresponding to the sampling time as analysis reports; when the coal slime parameters in the analysis report are stable, the analysis report is marked as a coal slime grading report and output; when the coal slime parameters in the analysis report fluctuate, all coal slime grading reports that overlap with the parameters in the coal slime parameter fluctuations in the analysis report are retrieved and marked as comparison reports; the number of overlapping fluctuating parameter values ​​is retrieved and the fluctuations are... The overlap value is obtained by calculating the difference between the overlapping parameter values ​​and the parameter values ​​in the analysis report. Specifically, the fluctuations in moisture difference and fixed carbon difference in the analysis report are compared with the fluctuations in moisture difference, volatile matter difference, and fixed carbon difference in the comparison report. Therefore, the overlapping parameters between the parameter value fluctuations in the analysis report and the comparison report are moisture and fixed carbon. The difference in the overlapping parameter value is calculated by subtracting the moisture difference and fixed carbon difference in the comparison report from the moisture difference and fixed carbon difference in the analysis report, and then taking the absolute value. The duration value is obtained by calculating the time difference between the sampling time in the analysis report and the sampling time in the comparison report.

[0061] The number of overlaps (HS), overlap value (HC), and duration value (SC) are calculated using a preset formula. The similarity value XSZ is obtained, where d1, d2, and d3 are preset weighting coefficients, and γ is a preset correction coefficient. As shown in the formula, the larger the overlap value, the greater the difference in parameter value fluctuations between the comparison report and the analysis report; the larger the duration value, the further the time distance between the comparison report and the analysis report, and the lower its reference value. Therefore, the larger the overlap, the smaller the overlap value, the smaller the duration value, and the larger the similarity value, the greater the reference value of the parameter value fluctuations in the comparison report for the parameter fluctuations in the analysis report. All comparison reports are sorted from largest to smallest according to their similarity values. Simultaneously, the sampling time and the corresponding coarse and fine coal slime separation process parameters of the comparison reports are retrieved and marked as report group three.

[0062] Report components one, two, and three are marked as coal slime grading reports and displayed and sent to the server for storage. This clearly shows the coal slime grading status at any given time, the fluctuation status of coal slime parameter values, and the specific fluctuation-related past coarse and fine coal slime separation process parameters, reducing the tedious steps for users to frequently investigate data and analyze coal slime separation processes with similar fluctuations.

[0063] In use, this invention compares the detected values ​​of coarse and fine coal slime with the standard content group of coarse and fine coal slime to obtain the relevant values ​​of moisture, ash, volatile matter, and fixed carbon. These four values ​​are then normalized to obtain the coarse and fine coal slime grade value, which is used to determine the grade of the coarse and fine coal slime, achieving rapid and accurate grading. The coal slime number, detected value, grade, and grade value are grouped into a report. When the coarse and fine coal slime is downgraded, the sampling time in the coal slime testing is analyzed to obtain the sampling value. Based on this, it is determined whether to accelerate the speed of the sampling robotic arm, analyze the grade value of the coarse and fine coal slime before and after adjustment, and quantify it to obtain the grade change value. Simultaneously, the grade change value is used to determine whether the current adjustment is effective. If ineffective, a coarse and fine coal slime sorting process adjustment signal is generated and sent to the server for display. This eliminates the possibility of inaccurate test results due to changes in the coal slime caused by long sampling time, making the detected values ​​of coarse and fine coal slime more accurate. The analysis of coal slime parameter values ​​determines the degree and duration of fluctuations, identifying whether the parameters are stable or fluctuating, along with the corresponding values ​​and fluctuation periods, and designates this as Report Group Two. Simultaneously, based on the time node in the information query, the system retrieves the sampling time closest to that time node and its corresponding Report Group One and Report Group Two. Analysis of Report Group One and Report Group Two reveals similar fluctuations in previous coal slime grading reports, and the corresponding coarse and fine coal slime separation process parameters are retrieved. Similar previous coal slime grading reports and their corresponding coarse and fine coal slime separation process parameters are designated as Report Group Three. Report Group One, Report Group Two, and Report Group Three are then designated as the Coal Sliming Report. This system clearly displays the coal slime grading status at any given time node, the fluctuation state of coal slime parameter values, and the specific related past coarse and fine coal slime separation process parameters, reducing the tedious steps of frequent data collection and analysis of coal slime separation processes with similar current fluctuations.

When the output is a parameter value fluctuation signal, if the parameter value is greater than the preset threshold, the system retrieves two time points corresponding to the parameter value and marks the time period corresponding to these two time points as the fluctuation time period. Specifically, when the output is a coal slime moisture difference fluctuation signal, a preset moisture threshold is used. If the coal slime moisture difference is greater than the preset coal slime moisture threshold, it indicates that the coal slime moisture difference is fluctuating significantly. In this case, the system retrieves two time points corresponding to the coal slime moisture difference and marks the time period corresponding to these two time points as the fluctuation time period.
