[0029] The present application embodiment provides an intelligent control system for a sand and gravel separator, such as Figure 1 As shown, the system comprises:

[0030] The sand and gravel separation target acquisition module 10 is used to determine the sand and gravel pile to be separated, and obtain the sand and gravel separation target of the sand and gravel pile to be separated, and the sand and gravel separation target is the target value of multiple separation indicators. Specifically, the sand and gravel pile to be separated refers to a sand and gravel pile body that needs to be subjected to sand and gravel separation operation, and these sand and gravel piles contain sand and gravel mixtures with different particle sizes, water contents and impurity contents. The specific area or pile body that needs to be separated is identified or located by preset geographic coordinates, image recognition (such as using a camera to shoot and identify the location of the sand and gravel pile) or manual input. After the area is identified, it is confirmed that the area is a sand and gravel pile to be separated by comparing it with the preset identification of the sand and gravel pile to be separated (such as a specific label, color or shape). Read the preset sand and gravel separation target, which refers to the sand and gravel quality index expected to be obtained after the sand and gravel separation operation, including particle size distribution (such as the ratio of sand and gravel in different particle size ranges), water content (the content of water in sand and gravel) and impurity content (such as the content of impurities such as soil, stone, and organic matter). These target values ​​are used to guide the sand and gravel separation operation to ensure that the separated sand and gravel meet specific quality requirements or usage requirements. The sand and gravel separation target is set based on industry standards, customer needs, or historical data.

[0031] The sand and gravel sample information acquisition module 20 is used to uniformly sample the sand and gravel pile to be separated, obtain multiple sand and gravel samples, collect information on the multiple sand and gravel samples, and obtain multiple sand and gravel sample information, wherein the sand and gravel sample information includes the particle size, water content and impurity content of the sand and gravel samples. Specifically, according to the size, shape and texture of the sand and gravel pile to be separated, multiple sampling points are determined through a preset algorithm or the experience of the operator. These sampling points are distributed at different positions and depths of the sand and gravel pile to ensure the representativeness of the samples. Use appropriate tools (such as shovels, samplers, etc.) to collect sand and gravel samples at selected sampling points, and collect sufficient sample volume at each sampling point for subsequent information collection and analysis. The collected sand and gravel samples are analyzed for particle size by screening method, laser particle size analyzer or other particle size measuring equipment. The proportion of sand and gravel in different particle size ranges in the sand and gravel samples is determined by particle size analysis; the moisture content of the sand and gravel samples is measured by moisture content measuring instruments (such as oven method, moisture meter, etc.), and the moisture content in the sand and gravel samples is measured and expressed as a percentage; the impurity content in the sand and gravel samples is detected by chemical analysis, spectral analysis or image recognition, where impurities include soil, stone, organic matter, etc., and their types and contents are specifically determined. The information such as particle size, moisture content and impurity content of each sand and gravel sample is recorded and integrated into a sand and gravel sample information database or data set.

[0032] A control parameter library generation module 30 is used to generate a control parameter library of the sand and gravel pile to be separated based on the multiple sand and gravel sample information and the sand and gravel separation target, and the control parameter library includes multiple sets of separation control parameters. Specifically, the control parameter library generation module 30 receives multiple sand and gravel sample information from the sand and gravel sample information acquisition module 20, including particle size, water content and impurity content, and reads the sand and gravel separation target, that is, the target value of multiple separation indicators, from the sand and gravel separation target acquisition module 10. Statistical analysis is performed on the sand and gravel sample information to determine the overall physical and chemical properties of the sand and gravel pile to be separated, such as particle size distribution, water content distribution and impurity content distribution, etc., analyze the relationship between the sand and gravel separation target and the sand and gravel sample information, and determine which control parameters have a direct impact on achieving the sand and gravel separation target. According to the sand and gravel separation target and sand and gravel sample information, multiple groups of separation control parameters are generated through algorithms or expert systems and stored in the control parameter library, wherein the separation control parameters are parameters used to configure the sand and gravel separator to achieve specific separation targets, including vibration frequency, screen aperture, flushing water volume, flushing time, etc. The control parameter library is a database that stores multiple groups of control parameters for guiding the sand and gravel separator to perform sand and gravel separation, and contains enough separation control parameter combinations to meet the needs of different sand and gravel piles and separation targets.

[0033] In a possible implementation, the control parameter library generation module 30 includes: a historical separation parameter library interaction unit, the historical separation parameter library interaction unit is used to interact with the historical separation parameter library, the historical separation parameter library includes historical sand and gravel information, historical separation control parameters and historical separation results. Specifically, the historical separation parameter library interaction unit establishes a data connection with the historical separation parameter library to access and retrieve the data in the library in real time, and reads the historical sand and gravel information, historical separation control parameters and corresponding historical separation results from the historical separation parameter library as needed, wherein the control parameters used in the past sand and gravel separation process and their corresponding sand and gravel information and separation results are stored in the historical separation parameter library, which can be used for parameter optimization and matching. A multiple-group separation control parameter acquisition unit, the multiple-group separation control parameter acquisition unit is used to bind the multiple sand and gravel sample information and the sand and gravel separation target respectively, input them into the historical separation parameter library, match them with the historical sand and gravel information and historical separation results, obtain the historical separation control parameters matching each sand and gravel sample information, and obtain multiple groups of separation control parameters. Specifically, each sand and gravel sample information is bound to the sand and gravel separation target to form a query request, the query request is input into the historical separation parameter library, matched with the historical sand and gravel information and the historical separation results, and the corresponding historical separation control parameters are extracted from the matching results as candidate parameters. The above steps are repeated for each sand and gravel sample information to obtain multiple groups of separation control parameters. A mapping storage unit is used to map and store multiple sand and gravel sample information and multiple groups of separation control parameters to generate a control parameter library. Specifically, each sand and gravel sample information is mapped one by one with its corresponding separation control parameter, and the mapping relationship is stored in the control parameter library to form a data set that can be used for subsequent query and use. This implementation method constructs a control parameter library by acquiring historical separation control parameters similar to the current sand and gravel sample information from the historical separation parameter library, thereby achieving the technical effect of improving the efficiency and pertinence of the control parameter library generation.

[0034] The sand and gravel material information acquisition module 40 to be separated is used to acquire the sand and gravel material to be separated, and collect information about the sand and gravel material to be separated to acquire information about the sand and gravel material to be separated. Specifically, the sand and gravel material to be separated is the sand and gravel input into the sand and gravel separator for separation each time, positioned to the sand and gravel pile to be separated, and confirmed by visual recognition or other sensor technology. The sand and gravel material to be separated is a part of the sand and gravel in the sand and gravel pile to be separated. According to the preset sampling rules, a certain number of representative samples are extracted from the sand and gravel material to be separated, and the same information as the multiple sand and gravel samples described in the sand and gravel sample information acquisition module 20 is collected for these samples to obtain information such as the particle size, water content, and impurity content of the sand and gravel material to be separated, and the various sand and gravel information collected is recorded in detail and integrated into a sand and gravel material information data set to be separated.

[0035] In a possible implementation, the sand and gravel information acquisition module 40 to be separated also includes: a feeding condition judgment unit, which is used to collect the material flow parameters of the sand and gravel to be separated in real time, and judge whether the sand and gravel to be separated meets the feeding conditions according to the material flow parameters and the rated processing capacity of the sand and gravel separator. Specifically, sensors or other measuring equipment are used to collect the material flow parameters of the sand and gravel to be separated in real time, including the flow rate, moisture content, particle size distribution, etc. of the sand and gravel, and obtain its rated processing capacity from the technical specifications or control system of the sand and gravel separator, that is, the maximum or recommended sand and gravel flow rate, moisture content and other parameter values ​​that the sand and gravel separator can handle under normal working conditions, compare the collected material flow parameters with the rated processing capacity of the sand and gravel separator, and judge whether the current sand and gravel to be separated meets the feeding conditions. The information collection unit of the sand and gravel to be separated is used to introduce the sand and gravel into the feed port of the sand and gravel separator if the feeding conditions are met, and obtain the information of the sand and gravel to be separated at the same time; if the feeding conditions are not met, the frequency of the feeding pump and the opening of the feeding valve are adjusted to control the material flow parameters until the feeding conditions are met, and then the sand and gravel are introduced into the feed port of the sand and gravel separator to obtain the information of the sand and gravel to be separated. Specifically, the judgment result of the feeding condition judgment unit is checked to confirm whether the sand and gravel to be separated meets the feeding condition. If the feeding condition is met, the sand and gravel are introduced into the feeding port of the sand and gravel separator through the feeding system (such as the feeding pump and the feeding valve). When the sand and gravel enter the sand and gravel separator, the detailed information of the sand and gravel to be separated is obtained by using sensors or other equipment, such as specific flow rate, actual moisture content, actual particle size distribution, etc.; if the feeding condition is not met, the frequency of the feeding pump (equipment for controlling the flow rate of sand and gravel, which changes the conveying speed of sand and gravel by adjusting the frequency) and the opening of the feeding valve (valve for controlling the flow rate of sand and gravel, which changes the flow rate of sand and gravel by adjusting the opening) are adjusted to control the material flow parameters. After the adjustment is completed, the feeding condition is checked again, and the steps of introducing sand and gravel and collecting information are performed until the conditions are met. This implementation method ensures that the sand and gravel separator operates within the rated processing capacity by setting the feeding condition judgment unit, avoids equipment damage or poor processing effect caused by overload or underload, and achieves the technical effect of ensuring the safe and stable operation of the sand and gravel separator.

[0036] The target separation control parameter acquisition module 50 is used to input the information of the sand and gravel to be separated into the control parameter library, match the information with multiple sand and gravel sample information, and obtain the target separation control parameters when there is matching information. Specifically, the information of the sand and gravel to be separated is received from the sand and gravel information acquisition module 40, including physical and chemical properties such as particle size distribution, water content, and impurity content. The sand and gravel information to be separated is compared with the multiple sand and gravel sample information in the control parameter library, that is, multiple parameters are compared one by one, including particle size distribution, water content, impurity content, etc. For each sand and gravel sample information, the matching degree between it and the sand and gravel information to be separated is calculated. The matching degree calculation can be based on different algorithms, such as Euclidean distance, cosine similarity, etc. According to the preset matching degree threshold, the sand and gravel sample information with a higher matching degree is screened out, and the separation control parameters corresponding to these sand and gravel sample information are used as candidate target separation control parameters. Among the candidate target separation control parameters, a group with the highest matching degree or the best comprehensive effect is selected as the target separation control parameter. Verify the acquired target separation control parameters to ensure their rationality and feasibility. For example, check whether the vibration frequency is within the allowable range of the equipment, whether the flushing water volume meets the supply conditions, etc. Output the verified target separation control parameters to the sand and gravel separator or other related equipment to guide the sand and gravel separation operation.

[0037] In a possible implementation, the target separation control parameter acquisition module 50 further includes: a separation parameter generation model construction unit, the separation parameter generation model construction unit is used to pre-construct a separation parameter generation model, and the separation parameter generation model is constructed based on the historical separation parameter library. Specifically, historical sand and gravel information, historical separation control parameters and corresponding historical separation results are extracted from the historical separation parameter library as training data, and the extracted historical data is pre-processed and feature extracted to identify key features that have a significant impact on the separation control parameters. Based on the extracted features, a suitable machine learning or deep learning algorithm is selected or designed to construct a separation parameter generation model. The separation parameter generation model is trained using the training data so that the separation parameter generation model learns the mapping relationship from sand and gravel information to separation control parameters. The trained separation parameter generation model is verified and evaluated by cross-validation, test set verification and the like to ensure its performance and generalization ability, and the trained separation parameter generation model is stored. A target separation control parameter generation unit, the target separation control parameter generation unit is used to input the sand and gravel information to be separated into the separation parameter generation model when there is no matching information, and obtain the target separation control parameters. Specifically, when there are no separation control parameters matching the information of the sand and gravel to be separated in the control parameter library, the information of the sand and gravel to be separated is input into the separation parameter generation model, and the separation parameter generation model automatically calculates the predicted separation control parameters based on the input sand and gravel information, verifies the predicted separation control parameters to ensure that they meet the operating range and restrictions of the equipment, and outputs the verified separation control parameters for configuring the sand and gravel separator. In this implementation method, when there are no separation control parameters that completely match the information of the sand and gravel to be separated in the control parameter library, the separation parameter generation model can make predictions based on the existing historical data and generate reasonable separation control parameter recommendations, achieving the technical effect of effectively coping with insufficient data.

[0038] The sand and gravel separation module 60 is used to configure the sand and gravel separator through the target separation control parameters, and control the sand and gravel to be separated for sand and gravel separation. Specifically, the sand and gravel separation module 60 receives the target separation control parameters from the target separation control parameter acquisition module 50, and adjusts the vibration system of the sand and gravel separator according to the vibration frequency setting value in the target separation control parameters (the vibration frequency affects the separation effect and speed of the sand and gravel to be separated on the screen), wherein the sand and gravel separator is a mechanical device for effectively separating the mixed sand and stone, including a feeding system, a screening system, a conveying system and a slag discharge system; according to the screen aperture specified in the target separation control parameters, the size of the screen aperture on the screen is selected or adjusted (screens with different apertures are used to separate sand and gravel of different particle sizes); according to the set value of the flushing water volume in the target separation control parameters, the water volume of the flushing system is controlled to ensure that the mud and impurities in the sand and gravel to be separated are effectively flushed away during the separation process. After the configuration is completed, the sand and gravel separator is started, the sand and gravel to be separated are separated, and the separation process is monitored in real time to ensure that the sand and gravel separator operates according to the set parameters. The embodiment of the present application adopts technical means such as generating a control parameter library of sand and gravel piles to be separated according to sand and gravel sample information and sand and gravel separation targets, matching in the control parameter library according to the sand and gravel information to be separated, obtaining target separation control parameters for sand and gravel separation, etc., to achieve the technical effect of accurately setting control parameters and improving the stability of sand and gravel separation.

[0039] In a possible implementation, the sand and gravel separation module 60 further includes: a sand and gravel separation product collection unit, which is used to collect the sand and gravel separation products after the sand and gravel materials to be separated are subjected to sand and gravel separation. Specifically, after the sand and gravel separator completes the sand and gravel separation operation, a special collection container or system is used to collect the sand and gravel separation products processed by the sand and gravel separator, and the collected sand and gravel separation products are classified and stored according to different types (such as sand, gravel, etc.). A sand and gravel separation index acquisition unit, which is used to evaluate the sand and gravel separation products based on the multiple separation indicators and obtain sand and gravel separation indicators. Specifically, multiple quantitative separation indicators for evaluating the sand and gravel separation effect are predefined, such as sand purity, gravel size distribution, etc., and corresponding measuring tools or equipment are used to measure and evaluate the collected sand and gravel separation products, obtain the specific values ​​of each separation indicator, and summarize and record the measured values ​​of each separation indicator to form a sand and gravel separation indicator report. A parameter optimization instruction generation unit, the parameter optimization instruction generation unit is used to compare the sand and gravel separation index with the sand and gravel separation target, and generate a parameter optimization instruction when the sand and gravel separation index does not meet the sand and gravel separation target. Specifically, the acquired sand and gravel separation index is compared and analyzed with the pre-set sand and gravel separation target. If the sand and gravel separation index does not meet the sand and gravel separation target, it is determined that parameter optimization is required, and a parameter optimization instruction is generated. The parameter optimization instruction is an instruction to optimize and adjust the target separation control parameters. A new separation control parameter acquisition unit is added, the new separation control parameter acquisition unit is used to optimize the target separation control parameters based on the parameter optimization instruction and obtain the new separation control parameters. Specifically, according to the parameter optimization instruction, the target separation control parameters are adjusted and optimized, such as adjusting the vibration frequency, the mesh aperture or the flushing water volume, to achieve a better separation effect, and the new separation control parameters (adjusted and optimized separation control parameters) are obtained, and the new separation control parameters are verified to ensure that they meet the equipment operation requirements and the sand and gravel separation target. A control parameter library adding unit is used to map and associate the information of the sand and gravel materials to be separated with the newly added separation control parameters, and add them to the control parameter library. Specifically, the information of the sand and gravel materials to be separated and the newly added separation control parameters are mapped and associated, and the associated information is added to the control parameter library, and the control parameter library is updated to ensure the accuracy and integrity of the data. This implementation method realizes closed-loop control from sand and gravel separation to parameter optimization by updating the control parameter library, achieving the technical effect of providing a more reliable reference and basis for subsequent sand and gravel separation operations.

[0040] In a possible implementation, the newly added separation control parameter acquisition unit includes: an indicator deviation extraction subunit, the indicator deviation extraction subunit is used to extract multiple indicator deviations of the sand and gravel separation indicator and the sand and gravel separation target. Specifically, the sand and gravel separation indicator provided by the sand and gravel separation indicator acquisition unit is compared with the preset sand and gravel separation target, and for each compared separation indicator, its deviation from the separation target is calculated. The deviation can be an absolute value deviation, a percentage deviation, etc., and the calculated multiple indicator deviations are extracted, wherein the indicator deviation reflects the difference or degree of difference between the sand and gravel separation indicator and the sand and gravel separation target, and is used to measure the gap between the current separation effect and the target effect. A sand and gravel separation simulation platform construction subunit, the sand and gravel separation simulation platform construction subunit is used to build a sand and gravel separation simulation platform, and the target separation control parameters and the multiple indicator deviations are input into the sand and gravel separation simulation platform. Specifically, according to actual needs, a suitable simulation tool or platform is selected to simulate the sand and gravel separation process, and a simulation environment similar to the actual sand and gravel separation environment is set in the simulation tool, including sand and gravel material characteristics, equipment parameters, etc. The target separation control parameters and multiple index deviations extracted from the index deviation extraction subunit are input into the sand and gravel separation simulation platform to simulate the sand and gravel separation process, wherein the sand and gravel separation simulation platform can simulate the separation effect under different separation control parameters, which is used to provide a reference for parameter optimization. The control parameter gradient adjustment subunit is used in the sand and gravel separation simulation platform to use the target separation control parameters as a reference, and to perform gradient adjustment on each control parameter in the target separation control parameters according to multiple index deviations to generate a newly added separation control parameter. Specifically, according to the separation effect simulated in the sand and gravel separation simulation platform, combined with multiple indicator deviations, the control parameters that need to be adjusted and their adjustment directions are determined. According to the size of the indicator deviation and actual needs, the adjustment step of the control parameters is set, that is, the amplitude of each adjustment. The target separation control parameters are used as the benchmark, and the control parameters are adjusted in a gradient manner according to the set adjustment direction and step size. The adjusted control parameters are input into the sand and gravel separation simulation platform again for simulation verification to observe whether the separation effect is improved. If the simulation verification results meet expectations, new separation control parameters are generated; otherwise, the above adjustment process is repeated. This implementation method achieves the technical effect of avoiding the risks and costs that may be directly brought about in actual operations by building a sand and gravel separation simulation platform and testing and adjusting the control parameters in a simulated environment.

[0041] like Figure 2As shown, in a possible implementation, the control parameter gradient adjustment subunit includes: a sand and gravel separation simulation space construction microunit, the sand and gravel separation simulation space construction microunit is used for the sand and gravel separation simulation platform to include a first sand and gravel separation simulation space and a second sand and gravel separation simulation space, wherein the first sand and gravel separation simulation space has a first adjustment step length, the second sand and gravel separation simulation space has a second adjustment step length, and the first adjustment step length is greater than the second adjustment step length. Specifically, two independent simulation spaces (virtual sand and gravel separation environments, used to simulate separation effects under different control parameters) are constructed in the sand and gravel separation simulation platform, namely the first sand and gravel separation simulation space and the second sand and gravel separation simulation space, a larger first adjustment step length is set in the first sand and gravel separation simulation space for global search; a smaller second adjustment step length is set in the second sand and gravel separation simulation space for local search. Wherein, the adjustment step length is the amplitude of adjusting the control parameters in the simulation space, and the larger the step length, the faster the parameter changes and the wider the search range. The first adjustment separation control parameter acquisition micro-unit is used to perform gradient adjustment on the target separation control parameter in the first sand and gravel separation simulation space according to the first adjustment step length to obtain the first adjustment separation control parameter; the first simulation result acquisition micro-unit is used to perform sand and gravel separation simulation according to the first adjustment separation control parameter to obtain the first simulation result; the preferred separation control parameter generation micro-unit is used to use the first adjustment separation control parameter as the preferred separation control parameter when the deviation of multiple indicators in the first simulation result is reduced. Specifically, according to the first adjustment step length, the target separation control parameter is gradient adjusted in the first sand and gravel separation simulation space. After the adjustment is completed, a new separation control parameter, i.e., the first adjustment separation control parameter, is obtained. The first adjustment separation control parameter is input into the sand and gravel separation simulation platform to perform sand and gravel separation simulation, and the separation result after simulation is obtained, including multiple indicator deviations. The multiple indicator deviations in the first simulation result are analyzed to determine whether they are reduced compared with the previous ones. If the deviations of multiple indicators are reduced, the first adjustment separation control parameter is used as the current optimal separation control parameter, i.e., the preferred separation control parameter. A second adjustment separation control parameter acquisition micro-unit, wherein the second adjustment separation control parameter acquisition micro-unit is used to perform gradient adjustment on the first adjustment separation control parameter in the second sand and gravel separation simulation space according to the second adjustment step length to obtain the second adjustment separation control parameter; a second simulation result acquisition micro-unit, wherein the second simulation result acquisition micro-unit is used to perform sand and gravel separation simulation according to the second adjustment separation control parameter to obtain a second simulation result; and a preferred separation control parameter update micro-unit, wherein the preferred separation control parameter update micro-unit is used to use the second simulation result as the preferred separation control parameter when the second simulation result is better than the first simulation result.Specifically, based on the first adjustment separation control parameter, according to the second adjustment step, a local gradient adjustment is performed in the second sand and gravel separation simulation space. After the adjustment is completed, a new separation control parameter, i.e., a second adjustment separation control parameter, is obtained. The second adjustment separation control parameter is input into the sand and gravel separation simulation platform to perform sand and gravel separation simulation and obtain the separation result after simulation, i.e., the second simulation result. The second simulation result is compared with the first simulation result to determine whether the second simulation result is better. If the second simulation result is better, the control parameter corresponding to the second simulation result is used as the new preferred separation control parameter. The parameter gradient iteration micro-unit is used to iteratively perform parameter gradient adjustment and use the final preferred separation control parameter as the newly added separation control parameter. Specifically, according to the simulation results and the adjustment of the control parameters, it is determined whether to continue the gradient adjustment iteration. If it is necessary to continue the iteration, it returns to the first adjustment separation control parameter acquisition micro-unit or the second adjustment separation control parameter acquisition micro-unit to perform a new round of gradient adjustment. When the iteration meets the termination condition, the final preferred separation control parameter is output as the newly added separation control parameter. This implementation method sets up two simulation spaces with different step sizes, which can quickly search for better control parameters in the global range, while making fine adjustments in the local range, achieving the technical effect of improving search efficiency and accuracy.

[0042] In a possible implementation, the second adjustment separation control parameter acquisition micro-unit also includes: a local parameter adjustment space construction sub-micro-unit, the local parameter adjustment space construction sub-micro-unit is used to construct a local parameter adjustment space with the first adjustment separation control parameter as the center and the first adjustment step as the span. Specifically, the size of the local parameter adjustment space is determined with the first adjustment separation control parameter (or the control parameter selected in the previous iteration) as the center and the first adjustment step (larger, used for global search) as the span, and on the basis of the center parameter, a local parameter adjustment space containing multiple possible control parameters is constructed according to the set span. The local parameter adjustment space is a multi-dimensional parameter range, each dimension corresponds to a control parameter, and is used to search for a better control parameter within a local range. The second sand and gravel separation simulation space configuration sub-micro-unit, the second sand and gravel separation simulation space configuration sub-micro-unit is used to configure the second sand and gravel separation simulation space according to the local parameter adjustment space. Specifically, the constructed local parameter adjustment space is obtained from the sub-micro unit of the local parameter adjustment space, and the second sand-stone separation simulation space is configured according to the parameter range in the local parameter adjustment space, including setting the parameter boundary, step size and other parameters in the simulation space. In the configured second sand-stone separation simulation space, the simulation is initialized using the initial or the control parameters selected in the previous iteration. This implementation method ensures that in each iteration, the search is concentrated in the local range near the control parameters selected in the previous iteration by setting the local parameter adjustment space, avoiding aimless global search and achieving the technical effect of more accurately searching for the local optimal solution.
