Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of material conveying applications, and particularly to an intelligent conveying and warehousing system for ceramic tiles; Background Art
[0002] In the modern ceramic tile production industry, conveying and warehousing are two important links. Generally, the produced ceramic tiles need to be transported through equipment such as conveyor belts and then stored in a warehouse. However, traditional conveying and warehousing methods often have many problems, such as low efficiency, high energy consumption, poor accuracy, etc. For example, in the process of conveying ceramic tiles, due to the unknown weight of the ceramic tiles, it is difficult to control the energy consumption and the efficiency is low. In addition, inaccurate prediction of the weight of ceramic tiles will also cause troubles to subsequent warehousing, sorting and other operations;
[0003] In the prior art, an intelligent material conveying device with the publication number of CN217554958U includes a silo. A first scraper conveyor is arranged at the bottom of the silo. A filtering device is arranged at the outlet of the first scraper conveyor. The filtering device includes a first support. A first elevator is bolted to the inner wall of the first support. The top of the first elevator is fixedly connected with an electric three-way. The bottom of the electric three-way is fixedly connected with a conduit. The bottom of the conduit is fixedly connected with a single-cylinder sieve for filtering and screening the materials in the silo. The single-cylinder sieve is communicated with a storage device through a bottom connecting pipe. The storage device includes a second elevator. A fixing frame is fixedly connected to the side wall of the second elevator near the top position; this prior art can monitor the operation status of the system in real time, master production data, and reduce human operation errors; improve the system safety, and greatly reduce the equipment maintenance time and cost;
[0004] In the actual operation process, there are still some problems. On the one hand, the prediction accuracy of the physical indexes of ceramic tiles by the existing system still needs to be improved. Excessive errors will affect the overall performance and efficiency of the system. On the other hand, there are still some deficiencies in the control of energy consumption by the existing system, and it is impossible to effectively save energy; in addition, in the existing technology, the correlation between physical indexes and energy consumption is often ignored, which makes the optimization of the system have certain limitations; when there is a certain correlation between the weight of ceramic tiles and energy consumption, if the parameters of the conveying process can be adjusted according to this correlation, the performance and efficiency of the system will be further improved;
[0005] The above information disclosed in the above background art section is only used to enhance the understanding of the background of the present disclosure. Therefore, it may include information that does not constitute the prior art known to those of ordinary skill in the art; Summary of the Invention
[0006] The purpose of the present invention is to provide an intelligent conveying and warehousing system for ceramic tiles to solve the problems raised in the above background art;
[0007] To achieve the above object, the present invention provides the following technical solutions:
[0008] An intelligent conveying and warehousing system for tiles, specifically including:
[0009] Marking module: Number each conveying stage experienced by the conveyor belt to form a sequence {1, 2,..., i,..., n}, where i represents the index of the i-th conveying process, and n represents the total number of conveying processes;
[0010] Data acquisition module: Used to collect the first physical index data and the first energy consumption data of the tiles during the i-th conveying process. The first physical index data includes but is not limited to the directly measured weight of the tiles;
[0011] Weight prediction module: Used to obtain the vibration data generated by the tiles with known weights on the conveyor belt, extract the vibration characteristic data from the vibration data, train a machine learning model using the vibration characteristic data, and through this machine learning model, construct a vibration analysis model. This vibration analysis model is used to perform real-time analysis on the vibration data of tiles with unknown weights, so as to predict the weight of the tiles;
[0012] Threshold comparison module: Used to perform a threshold comparison between the directly measured tile weight result in the first physical index data and the tile weight indirectly predicted by the vibration analysis model to determine the final weight of the tiles;
[0013] Data preprocessing module: Used to preprocess the first physical index data and the first energy consumption data after obtaining them, remove outliers and noise, and perform standardization processing on the data;
[0014] First correlation module: Used to obtain the preprocessed first physical index data and the first energy consumption data, and perform correlation analysis on these two types of data to obtain a first correlation coefficient. The first correlation coefficient is used to evaluate the degree of association of the i-th conveying process;
[0015] Energy consumption construction module: Used to obtain the first energy consumption data of n conveying processes, perform calculation and analysis to obtain the total energy consumption value, and set the energy consumption expected value of the i-th conveying process according to the total energy consumption value;
[0016] Optimal energy consumption selection module: Used to set a preset threshold for the first correlation coefficient. If the first correlation coefficient is lower than the preset threshold, adjust the set value of the first physical index data to ensure that the energy consumption value of the i-th conveying process does not exceed its corresponding energy consumption expected value.
[0017] Furthermore, define the total energy consumption value as E, and the calculation formula is as follows:
[0018]
[0019] Among them, E represents the total energy consumption; w 1 , w 2 , w 3 are the positive weights of the conveying time, motor power, and conveyor belt tension respectively. is an exponential function used to process the motor power, and ln(1 + DZli) is a natural logarithmic function. is a cube root function used to process the conveying time. The smaller E is, the lower the energy consumption and the more efficient the conveying process; conversely, the larger E is, the higher the energy consumption and the less efficient the conveying process.
[0020] Define the expected energy consumption value Ei for the i-th conveying process as follows:
[0021]
[0022] Among them, Ei represents the expected energy consumption value for the i-th conveying process, which is an average value of the total energy consumption.
[0023] Furthermore, set the preset threshold of the first correlation coefficient. If the first correlation coefficient is lower than the preset threshold, adjust the set value of the first physical index data to ensure that the energy consumption value of the i-th conveying process does not exceed its corresponding expected energy consumption value. The specific content is as follows:
[0024] Set the preset threshold of Ri to 0.4. When Ri < 0.4, it indicates that the correlation degree between the physical index and the energy consumption data is relatively low and needs to be optimized.
[0025] If Ri is between 0 and 0.2, the adjustment strategy is to reduce the expected energy consumption by 20%. Specifically as follows:
[0026] Increase the conveying speed Svi to 120% of the current value;
[0027] Reduce the conveying distance Sdi to 80% of the current value;
[0028] Increase the processing capacity of the tile weight Zli to 150% of the current value;
[0029] If Ri is between 0.2 and 0.4, the adjustment strategy is to reduce the expected energy consumption by 10%. Specifically as follows:
[0030] Increase the conveying speed Svi to 110% of the current value;
[0031] Reduce the conveying distance Sdi to 90% of the current value;
[0032] Increase the processing capacity of the tile weight Zli to 120% of the current value.
[0033] Compared with the prior art, the beneficial effects of the present invention are as follows: The marking module numbers the conveying stages to achieve precise tracking and improve the operating efficiency of the system; the data acquisition module monitors the tile status and energy consumption in real time to optimize resource allocation and reduce costs; the weight prediction module uses machine learning to predict the tile weight, improving automation and prediction accuracy; the threshold comparison module verifies the weight prediction to ensure product quality; the first correlation module analyzes the relationship between physical indicators and energy consumption to provide a basis for energy consumption management; the energy consumption construction module sets the expected energy consumption value to optimize energy use; the optimal energy consumption selection module adjusts the set value not to exceed the expected energy consumption to achieve energy conservation and cost optimization.

[0086] Example 4:
[0087] On the basis of Example 3, further illustrate that the vibration data generated by tiles of known weight on the conveyor belt is obtained, and the vibration characteristic data in the vibration data is extracted. The machine learning model is trained using the vibration characteristic data, and through this machine learning model, a vibration analysis model is constructed. This vibration analysis model is used to perform real-time analysis on the vibration data of tiles of unknown weight, so as to predict the weight of the tiles.

In this embodiment, the selection of the kernel function and the regularization parameter are used to optimize the model performance; by observing the performance of the model during the cross-validation process, find the parameters that need to be adjusted, such as the selection of the kernel function and the regularization parameter. Then, by adjusting these parameters, optimize the performance of the model; this step often requires multiple attempts and comparisons until the optimal parameter settings are found. This technical means is prior art and will not be elaborated;
[0094] Use the trained machine learning model to analyze the vibration data of tiles with unknown weights and predict the tile weights in real time.
[0095] Example Five:
[0096] Based on Example Four, further illustrate that compare the directly measured tile weight result in the first physical index data with the tile weight indirectly predicted by the vibration analysis model through a threshold to establish the final weight of the tiles, specifically including the following content:
[0097] 1) Obtain the predicted result of the tile weight and the directly measured tile weight data. Mark the directly measured tile weight as Wsensor, and mark the tile weight indirectly predicted by the vibration analysis model as Wvibration. Set the comparison threshold as ΔW. If |Wsensor - Wvibration| ≤ ΔW is satisfied, then take Wsensor as the finally determined tile weight. If not satisfied, then proceed to step 2);
[0098] 2) Correct Wsensor, and the correction formula is:
[0099] Wcorrected = Wsensor + β 1 ·Factor 1 +β 2 ·Factor 2 +β 3 ·Factor 3
[0100] In the above formula, Wcorrected is the corrected tile weight;
[0101] β 1 is the influence coefficient of the sensor performance on the difference; β 2 is the influence coefficient of the environmental factor on the difference; β 3 is the influence coefficient of the vibration analysis model error on the difference; Factor 1 is the correction factor of the sensor performance, Factor 2 is the correction factor of the environmental factor, Factor 3 is the correction factor of the vibration analysis model error;
[0102]
[0103] Among them, β 1 , β 2 , β 3 , Factor 1 , Factor 2 , Factor 3 , β 1 <β 2 <β 3 , β 1 , β 2 , β 3 are all determined by the expert group according to the experimental data and the results of regression analysis, Factor 1 <Factor 2 <Factor 3 , and can be adjusted according to the actual usage situation;
[0104] 3) Determine whether |Wcorrected - Wvibration| ≤ ΔW is satisfied. If it is satisfied, then use Wcorrected as the finally determined weight of the tile. If it is not satisfied, then use Wcorrected as the directly measured weight of the tile and re - correct it through step 2).
[0105] Example Six:
[0106] Based on Example Five, further explanation is given. Define the first correlation coefficient as Ri, and the mathematical formula is as follows:

[0110] a, b, c, d, e, f, g are positive weight coefficients, a < b < c < d < e < f < g, and a + b + c + d + e + f + g = 1, which need to be determined through experiments or experience according to the actual situation;
[0111] The value range of Ri is (0, 1);
[0112] In this embodiment, the weight of the tile is divided at 30 kg. If it is greater than 30 kg, it is defined as "larger", and if it is less than 30 kg, it is defined as "lighter";
[0113] Conveying distance: Divided at 50 m. If it is greater than 50 m, it is defined as "longer", and if it is less than 50 m, it is defined as "shorter";
[0114] Conveying speed: Divided at 2 m / s. If it is greater than 2 m / s, it is defined as "faster", and if it is less than 2 m / s, it is defined as "slower";
[0115] Tile volume: Divided at 0.015 m³. If it is greater than 0.015 m³, it is defined as "larger", and if it is less than 0.015 m³, it is defined as "smaller";
[0116] Conveying time: Divided at 10 minutes. If it is greater than 10 minutes, it is defined as "longer", and if it is less than 10 minutes, it is defined as "shorter";
[0117] Motor power: Taking 5 kW as the dividing point, greater than 5 kW is defined as "higher", and less than 5 kW is defined as "lower".
[0118] Conveyor belt tension: Taking 10 N as the dividing point, greater than 10 N is defined as "higher", and less than 10 N is defined as "lower".

[0145] In a specific scenario, assume that the weight g of the conveyor belt tension DZli is determined to be 20%; based on this determined value, the proportion of the conveyor belt tension DZli in the first correlation coefficient Ri is 20%, which means that the influence of the conveyor belt tension DZli is relatively large when calculating Ri; by increasing the weight of the conveyor belt tension, the influence of the conveyor belt tension on energy consumption can be more accurately reflected, thereby optimizing the conveying process;
[0146] When the conveyor belt tension is low, the percentage range of the weight g of the conveyor belt tension DZli is 5% to 15%; the influence of the conveyor belt tension on energy consumption is relatively small;
[0147] In a specific scenario, assume that the weight g of the conveyor belt tension DZli is determined to be 10%; based on this determined value, the proportion of the conveyor belt tension DZli in the first correlation coefficient Ri is 10%, which means that the influence of the conveyor belt tension DZli is relatively small when calculating Ri; by reducing the weight of the conveyor belt tension, the influence of the conveyor belt tension on energy consumption can be more accurately reflected, thereby optimizing the conveying process;
[0148] When Ri is closer to 0, it indicates that the degree of correlation between the physical index and the energy consumption data is lower, and the conveying process needs to be optimized;
[0149] When Ri is closer to 1, it indicates that the degree of correlation between the physical index and the energy consumption data is higher, and the conveying process is more efficient;
[0150] When Ri is between 0 and 0.2, it indicates that the degree of correlation between the physical index and the energy consumption data is extremely low; this means that there is a large amount of energy waste or inefficient processes in the conveying process; in this case, it is necessary to review the entire conveying process from beginning to end, identify the inefficient links, and seek improvement solutions; it is necessary to consider replacing with high-efficiency equipment, or improving the process flow, or retraining the operators;
[0151] When Ri is between 0.2 and 0.4, it indicates that the correlation degree between the physical index and the energy consumption data is relatively low; in this case, although the transportation process still needs to be optimized, a comprehensive reform is not required; starting from the part with poor physical indicators, if the correlation coefficient of speed is low, it is necessary to consider increasing the transportation speed or optimizing the control strategy of the transportation speed;
[0152] When Ri is between 0.4 and 0.6, it indicates that the correlation degree between the physical index and the energy consumption data is average; in this case, partial optimization of the transportation process is required; through more refined data analysis, find out the situations where the energy consumption is high under certain specific conditions, and then optimize for these situations;
[0153] When Ri is between 0.6 and 0.8, it indicates that the correlation degree between the physical index and the energy consumption data is relatively high; at this time, some details need to be optimized. Through refined energy consumption monitoring, find small fluctuations in energy consumption, and then adjust the equipment parameters to make the energy consumption more stable;
[0154] When Ri is between 0.8 and 1, it indicates that the correlation degree between the physical index and the energy consumption data is very high, and the transportation process is already very efficient at this time; but in order to achieve higher efficiency, some fine-tuning can be carried out. Through more refined data analysis, find small-scale but frequent energy consumption fluctuations, and then optimize the control strategy to reduce these fluctuations.
[0155] Example Seven:
[0156] On the basis of Example Six, it is further explained that the total energy consumption value is defined as E, and the calculation formula is as follows:
[0157]
[0158] Among them, E represents the total energy consumption; w 1 、w 2 、w 3 are the positive weights of the transportation time, motor power, and conveyor belt tension respectively, and w 1 +w 2 +w 3 =1, w 1 <w 2 <w 3 The positive weight indicates that the weight is a positive number, and these weights are set according to the actual situation, based on the statistical analysis of historical data or the expert's experience judgment;
[0159] is an exponential function used to process the motor power because the influence of the motor power on the total energy consumption is exponential;
[0160] ln(1 + DZli) is the natural logarithm function. Adding 1 is to avoid the situation where the logarithmic function cannot be calculated when the conveyor belt tension DZli is 0. This function is used to process the conveyor belt tension;
[0161] is the cube root function and is used to process the conveying time because the influence of the conveying time on the total energy consumption is at the cube root level;
[0162] The smaller E is, the lower the energy consumption and the more efficient the conveying process; conversely, the larger E is, the higher the energy consumption and the less efficient the conveying process;
[0163] Define the expected energy consumption value Ei for the i-th conveying process as follows:
[0164]
[0165] Among them, Ei represents the expected energy consumption value for the i-th conveying process and is an average value of the total energy consumption.
[0166] Example Eight:
[0167] Based on Example Seven, further illustrate. Set the preset threshold of the first correlation coefficient. If the first correlation coefficient is lower than the preset threshold, adjust the set value of the first physical index data so that the energy consumption value of the i-th conveying process is within the corresponding expected energy consumption value. The specific content includes the following:
[0168] Set the preset threshold of Ri to 0.4. When Ri < 0.4, it means that the degree of correlation between the physical index and the energy consumption data is relatively low and needs to be optimized; this threshold is determined based on historical data analysis and is aimed at distinguishing the conveying processes with poor efficiency;
[0169] If Ri is between 0 and 0.2, the adjustment strategy is as follows:
[0170] Increase the conveying speed Svi to 120% of the current value to improve efficiency;
[0171] Reduce the conveying distance Sdi to 80% of the current value to reduce unnecessary length by optimizing the path;
[0172] Increase the processing capacity of the tile weight Zli to 150% of the current value by upgrading equipment or improving the process;
[0173] Increasing Svi will directly improve the conveying efficiency, and it is expected to reduce the impact on the total energy consumption by 10%;
[0174] Reducing Sdi helps to reduce energy consumption, and the impact is to reduce energy consumption by 5%;
[0175] Increasing Zli represents higher batch processing efficiency and reduces the energy consumption per unit product. It is expected to reduce energy consumption by 5%;
[0176] The above adjustment reduces the expected energy consumption by 20%;
[0177] If Ri is between 0.2 and 0.4, the adjustment strategy is as follows:
[0178] Increase the conveying speed Svi to 110% of the current value to slightly improve the efficiency;
[0179] Reduce the conveying distance Sdi to 90% of the current value and reduce part of the length by fine-tuning the path;
[0180] Increase the processing capacity of the tile weight Zli to 120% of the current value by optimizing the operation process;
[0181] Increasing Svi improves the conveying efficiency, and the expected impact on the total energy consumption is 6%;
[0182] Reducing Sdi reduces the energy consumption by shortening the distance, and the expected impact on the energy consumption is 2%;
[0183] Increasing Zli improves the batch efficiency, is expected to reduce the energy consumption per unit product, and the expected impact on the energy consumption is 2%;
[0184] The above adjustment reduces the expected energy consumption by 10%;
[0185] The increase in the speed Svi significantly improves the conveying efficiency because a high speed means that more products can be processed in the same time, thus spreading the energy consumption per single tile;
[0186] The reduction of the distance Sdi directly affects the calculation of the energy consumption because less energy is consumed for short-distance conveying;
[0187] The increase in the tile weight Zli has a significant impact on the production efficiency because a larger batch can more effectively spread the energy consumption of equipment startup and operation.
[0188] Example Nine:
[0189] On the basis of Example Eight, it is further illustrated that in this example, this system uses the optimal energy consumption selection module to optimize the production process to achieve the goal of minimizing energy consumption and improving production efficiency;
[0190] In the test preparation stage, a threshold value of the associated number Ri is analyzed from the historical data. This threshold value can clearly distinguish between low-efficiency and high-efficiency conveying processes. The set Ri threshold value is 0.4. When the actual Ri value is lower than this threshold value, it means that the current production process has a low correlation with the energy consumption and needs to be optimized;
[0191] The weighting factors a, b, c, d, e, f, g are determined through experiments or experience to balance the influence weights of various physical indicators in the total energy consumption, and these weighting coefficients remain unchanged in each optimization adjustment;
[0192] It is expected that through the above optimization strategies, the efficiency of the production process can be improved and the energy consumption can be minimized to the greatest extent;
[0193] The following is the data table obtained after five tests:
[0194]
[0195]
[0196] The data analysis of the table is as follows:
[0197] By presetting the threshold of the correlation coefficient Ri and combining specific physical indicators, such as the conveying speed Svi, the conveying distance Sdi, and the tile weight Zli for adjustment, the conveying process is optimized, so that the energy consumption value of each conveying process falls within the expected value of the corresponding energy consumption;
[0198] 1. The energy consumption is significantly reduced:
[0199] From Test 1 to Test 5, the actual energy consumption E decreased from 150 kWh to 100 kWh, and the expected energy consumption Ei decreased from 130 kWh to 90 kWh. This indicates that through the adjustment strategy of the present invention, the energy consumption is reduced by 33.33%;
[0200] 2. The effectiveness and adaptability of the adjustment strategy:
[0201] The process of gradually approaching the preset threshold of 0.4 for the Ri value by adjusting Svi, Sdi, and Zli demonstrates the adaptability and effectiveness of the adjustment strategy; this process of gradual adjustment and optimization reflects the innovation and novelty of the present invention;
[0202] 3. The matching degree between the expected and actual energy consumption values is improved:
[0203] As the tests proceed, the gap between the actual energy consumption and the expected energy consumption gradually decreases, indicating that the coincidence degree between the expected calculation and the actual operation is continuously improved, which further verifies the accuracy and reliability of the formula and the adjustment strategy;
[0204] The increase in the conveying speed Svi has a significant impact on the reduction of energy consumption; from Test 1 to Test 5, Svi gradually increases, and the total energy consumption significantly decreases; this is because increasing the conveying speed can complete the same amount of work in a shorter time, thereby reducing energy consumption;
[0205] The reduction of the conveying distance Sdi is closely related to the reduction of energy consumption; by optimizing the conveying path and reducing unnecessary conveying distance, the energy consumption is directly reduced, which reflects the high efficiency of the strategy of the present invention;
[0206] The increased processing capacity of the tile weight Zli means that more tiles can be processed at a time, which not only improves the production efficiency, but also means that the energy consumption per kilogram of tiles is reduced. The resulting reduction in energy consumption further verifies the scientificity and rationality of the adjustment strategy;
[0207] After the adjustment by the strategy of the present invention, not only the energy consumption is significantly reduced, but also the energy consumption value of each conveying process can be ensured to fall within the expected energy consumption value, which reflects the specific technical effect in the implementation of the present invention.
