[0029] Embodiment 1

[0030] like Figure 1 As shown, an embodiment of the present application provides a monitoring and control method for a sand and gravel separator, the method is applied to a monitoring and control system, the system includes a monitoring and control device, the monitoring and control device includes an image acquisition device and a gravity sensor, and the method includes:

[0031] Specifically, the monitoring and control device is used to monitor and collect data during the monitoring process of the sand and gravel separator, and communicate and transmit the collected data to the monitoring and control system. The monitoring and control system analyzes and calculates the received data, obtains the corresponding control instructions, connects to the controller of the sand and gravel separator, sends the corresponding control adjustment instructions, and operates and controls the sand and gravel separator. The image acquisition device is a device for image acquisition, which acquires images of the sand and gravel, mixed liquid, separation results, etc. that need to be imaged. The gravity sensor is set on the side wall of the separator, and the gravity sensor senses and detects the pressure on the side wall of the separator.

[0032] Step S100: obtaining first image information through an image acquisition device, wherein the first image information includes the total amount of sand and gravel to be separated;

[0033] Specifically, images of the sand and gravel that need to be separated are collected through image acquisition equipment such as a camera. The first image information is an overall image of the sand and gravel to be separated, covering all states of the sand and gravel to be separated, including quantity and shape.

[0034] Step S200: obtaining sand and gravel amount information according to the first image information;

[0035] Further, such as Figure 2 As shown, the step S200 of obtaining the sand and gravel amount information according to the first image information includes:

[0036] Step S210: setting a first reference object, wherein the first reference object has a first weight;

[0037] Step S220: obtaining acquisition feature information according to the first image information;

[0038] Step S230: performing image acquisition on the first reference object based on the acquisition feature information to obtain third image information;

[0039] Step S240: extracting features from the first image information and the third image information to obtain first image features and second image features;

[0040] Step S250: obtaining a first corresponding relationship according to the first weight and the second image feature;

[0041] Step S260 obtains the gravel amount information based on the first corresponding relationship and the first image feature.

[0042] Specifically, the sand and gravel to be analyzed are usually located in a mixer truck, which is not convenient for measurement. At the same time, the measurement process is time-consuming and labor-intensive, and the error rate is large. In order to improve the rapid identification and measurement of the sand and gravel to be separated, the embodiment of the present application utilizes the processing and statistics of image features. By setting a first reference object, the first reference object is an object with a specific weight, namely, a first weight, and has a reference significance for sand and gravel measurement, such as sand and gravel per unit volume, and acquires the first image information. The acquisition feature information is the parameters in the process of acquiring the first image information, such as acquisition angle, acquisition pixels, acquisition distance, light environment, etc. The image of the first reference object is acquired according to the same acquisition feature information to ensure that the first image information The imaging effects of the third image information are similar, and the sand and gravel to be separated in the first image information can be accurately identified and quantitatively analyzed. By extracting image features of the first reference object with known weight and volume in the third image information, the second image feature is the image feature of the first reference object, and the corresponding calculation relationship between the first weight and the second image feature, that is, the first corresponding relationship, is obtained. The first image feature is the result of image feature extraction of the first image information. Based on the first corresponding relationship, that is, the mapping relationship between the image feature and the weight, the image features of the sand and gravel to be separated in the first image information are converted and analyzed to obtain the corresponding weight information of the sand and gravel to be separated in the first image feature, that is, the sand and gravel quantity information.

[0043] Step S300: input the sand and gravel amount information into the evaluation model to obtain water injection amount information;

[0044] Further, such as Figure 3 As shown, the sand and gravel amount information is input into the evaluation model to obtain the water injection amount information, and step S300 includes:

[0045] Step S310 constructs a neural network model;

[0046] Step S320: obtaining historical processing data, wherein the historical processing data includes information on the separation effect of the amount of sand and gravel processed and the amount of water injected;

[0047] Step S330: screening the analysis effect information according to preset requirements to obtain a screening processing data set, wherein the screening processing data set includes a processing sand and gravel volume and a water injection volume;

[0048] Step S340: obtaining model training data according to the screened and processed data set, training the neural network model through the model continuous data, and obtaining the evaluation model;

[0049] Step S350 obtains a second output result of the evaluation model, where the second output result includes the water injection volume information.

[0050] Specifically, the amount of water added is calculated according to the information of the amount of sand and gravel. Since the separation process requires the use of high-speed water flow to separate the sand and gravel, the amount of water for the sand and gravel to enter needs to be determined according to the state weight of the sand and gravel to be separated, so that the concentration of the sand and gravel mixed liquid obtained after adding water meets the separation requirements. The concentration of the sand and gravel mixed liquid has a certain influence on the separation effect. Too high or too low concentration is not conducive to separation. It is meaningful to keep it within a suitable concentration range to improve the separation effect. In order to improve the accuracy of force assessment, this application adds a neural network model, uses the historical data of previous operation separation to train the model, and uses the full concentration in the historical processing data The historical data of the foot separation effect is used as a training sample, and training data is randomly extracted from it to train the neural network model. The training process is essentially a supervised learning process. Each group of supervised data includes identification information of the amount of sand and gravel to be processed and the amount of water injection to be identified. The amount of sand and gravel to be processed is input into the neural network model. According to the identification information used to identify the amount of water injection, the neural network model continuously self-corrects and adjusts until the output result obtained is consistent with the identification information, then the supervised learning of this group of data is terminated and the supervised learning of the next group of data is carried out; when the output information of the neural network model reaches a predetermined accuracy rate / reaches a convergence state, the supervised learning process ends. Through supervised learning of the neural network model, the neural network model can process the input information more accurately, and the output water injection information can be more reasonable and accurate, so as to achieve the effect of accurately configuring the sand and gravel mixed liquid and improve the accuracy of the evaluation. The evaluation model is a trained and converged neural network model. Neural Networks (NN) is a complex neural network system formed by a large number of simple processing units (called neurons) that are widely connected to each other. It reflects many basic characteristics of human brain functions and is a highly complex nonlinear dynamic learning system. The neural network model is described based on the mathematical model of neurons. Artificial Neural Networks (ANN) is a description of the first-order characteristics of the human brain system. Simply put, it is a mathematical model. Through the training of a large amount of training data, the total amount of sand and gravel to be separated is input into the neural network model, and the matching water injection amount information is output, so as to realize the automatic evaluation of the water injection amount through computer machine learning, ensure that the mixed concentration of the sand and gravel mixture meets the separation effect, and effectively improve the operation efficiency and the reliability of the evaluation results by adding artificial intelligence technology, so as to avoid the errors caused by manual experience operation and affect the separation effect.

[0051] Step S400 obtains a torsion strength rule list, wherein the torsion strength rule list includes a correspondence between a sand-gravel mixture to be stirred, torsion strength, and separation results;

[0052] Specifically, the torsional strength rule list is a mapping relationship between torsional strength and sand-gravel mixture, torsional strength and separation results constructed according to historical data. It is data accumulated through practice and can ensure the reliability of the corresponding relationship. Different torsional strengths are set according to the weight and state of the sand-gravel mixture through the data relationship in the torsional strength rule list to obtain different separation results. Therefore, according to the torsional strength rule list, it is possible to achieve the matching of the corresponding torsional strength based on the requirements of the set separation results according to the weight of the sand-gravel mixture to be stirred.

[0053] Step S500: based on the torsional strength rule list, according to the water injection amount information and the sand and gravel amount information, obtain predicted torsional strength information;

[0054] Step S600 obtains a torsion control strategy based on the predicted torsion strength information, and controls the stirring speed of the sand and gravel separator according to the torsion control strategy.

[0055] Specifically, the weight and concentration information of the sand and gravel mixture to be separated are obtained according to the water injection information and the sand and gravel amount information. The corresponding separation result and torsional strength matching analysis are performed in the torsional strength rule list based on the obtained weight and concentration information of the sand and gravel mixture. After the separation result is ensured, the corresponding torsional strength can be obtained. If the separation result is certain, the corresponding torsional strength is determined according to the weight of the mixture to achieve the separation result. The torsional strength information is predicted, that is, the torsional strength matched with the mixed liquid information obtained according to the water injection information and the sand and gravel amount information. Different separation effects can be achieved by selecting different torsional strengths for sand and gravel mixtures with different weight and form requirements. Generally, a faster torsional speed will achieve a better separation effect, but too fast a torsional speed will cause energy consumption and equipment wear. How to balance the separation effect and equipment loss is the technical problem solved by the present application. The required torsional strength is calculated based on the weight of the liquid. The precise matching calculation of historical experimental data can avoid the influence of too low torsion on the separation effect and the equipment loss caused by too high torsion. The torsion control strategy includes setting the startup power of the sand and gravel separator, controlling the torsion speed and the torsion strength control during the entire separation process. For example, the startup speed is A, then accelerates to B and then remains stable. The set torsion control strategy is used to control the operation of the sand and gravel separator, and the corresponding separation control is achieved according to the specific state of the sand and gravel to be separated, which not only ensures the separation effect of sand and gravel, but also avoids unnecessary energy consumption and wear of the equipment. At the same time, the analysis and calculation process adds artificial intelligence technology to improve the calculation efficiency and result accuracy through machine learning, which solves the problem that the sand and gravel separator in the prior art operates according to a predetermined mode without considering the specific characteristics of the separated sand and gravel, and thus has the technical problem of poor sand and gravel separation effect and uncontrollable energy loss.

[0056] Further, such as Figure 4 As shown, the method includes:

[0057] Step S710: obtaining second image information through the image acquisition device, wherein the second image information includes characteristic information of the sand-gravel mixture;

[0058] Step S720: extracting features from the second image information to obtain feature information of the sand-gravel mixture;

[0059] Step S730: inputting the sand-gravel mixture characteristic information and the sand-gravel quantity information into a state evaluation model, wherein the state evaluation model is obtained through training convergence of multiple sets of training data, wherein each set of training data includes the sand-gravel mixture characteristic information, the sand-gravel quantity information, and identification information identifying the sand-gravel mixture concentration;

[0060] Step S740: obtaining a first output result of the state evaluation model, wherein the first output result includes a mixed state evaluation result, and the mixed state evaluation result is used to indicate the concentration of the sand-gravel mixed solution that matches the input sand-gravel mixed solution characteristic information and sand-gravel amount information;

[0061] Step S750 determines whether the mixed state evaluation result meets the first predetermined condition;

[0062] When the condition is not satisfied in step S760, the supplementary water injection amount information is obtained based on the mixed state evaluation result.

[0063] Specifically, during the sand and gravel separation process, the sand and gravel need to be stirred. For the sand and gravel mixture with high concentration, clean water needs to be added for stirring so that it is stirred evenly. Usually, how much water to inject and whether water injection is needed are manually judged, and its accuracy is inevitably affected by human factors. In the embodiment of the present application, the sand and gravel mixture is monitored in real time during the stirring process, and the stirred sand and gravel mixture is obtained by an image acquisition device. The second image information is the acquisition of the characteristics of the sand and gravel mixture during stirring. The image acquisition device is used to perform real-time image acquisition of the sand and gravel mixture during the stirring process, and the image information is used to extract the characteristic information of the sand and gravel mixture. The characteristic information of the sand and gravel mixture mainly reflects the concentration of the sand and gravel mixture, which is reflected by the mixing degree and fluidity parameters of the liquid. The characteristic information of the sand and gravel mixture and the sand and gravel amount information are comprehensively analyzed to determine whether the current mixture is stirred evenly and whether the concentration meets the requirements. If the concentration of the mixture is high, water injection is required. The amount of water injection is calculated according to the difference between the concentration and the requirement. The water pump is controlled to inject water according to the calculated amount of water injection to realize the automatic adjustment process of the concentration of the sand and gravel mixture, ensuring that the sand and gravel mixture is conducive to separation. Within the concentration range, in order to improve the accuracy of the mixed solution concentration evaluation results, the embodiment of the present application adds artificial intelligence technology, and analyzes and evaluates the concentration through machine deep learning. The state evaluation model is a neural network model through machine learning, and the training of the neural network model is converged using historical experimental data. The state evaluation model is obtained through training convergence through multiple sets of training data, and each set of training data includes sand and gravel mixed solution characteristic information, sand and gravel amount information, and identification information identifying the sand and gravel mixed concentration. The model learns that the sand and gravel mixed solution concentration evaluation algorithm is calculated and processed according to the input sand and gravel mixed solution characteristic information and sand and gravel amount information to obtain the sand and gravel mixed concentration information that matches it, that is, the mixed state evaluation result, which improves the calculation speed and calculation accuracy, and lays a solid foundation for accurate sand and gravel mixed solution concentration adjustment. When the mixed state evaluation result does not meet the first predetermined condition, the difference is calculated according to the mixed state evaluation result and the concentration value in the first predetermined condition, and the water injection amount is calculated according to the difference combined with the total amount of sand and gravel. The control operation of the water injection amount is performed according to the calculation result to ensure the concentration of the sand and gravel mixed solution, thereby ensuring the separation effect.

[0064] Furthermore, the method comprises:

[0065] Step S810: obtaining a first sensing force set and a second sensing force set through a gravity sensor, wherein the first sensing force set corresponds to a first position area, and the second sensing force set corresponds to a second position area;

[0066] Step S820: obtaining a first uniformity and a second uniformity according to the first sensing force set and the second sensing force set respectively;

[0067] Step S830: respectively judging whether the first uniformity and the second uniformity meet a second predetermined condition, and obtaining a judgment result;

[0068] Step S840 obtains an adjustment control strategy according to the judgment result.

[0069] Further, the control strategy is adjusted according to the judgment result, and step S840 includes:

[0070] Step S841: when the judgment result is the first result, the adjustment control strategy is to increase the stirring speed;

[0071] In step S842, when the judgment result is the second result, the adjustment control strategy is to maintain the stirring speed.

[0072] Specifically, the impact force of sand and gravel on the side wall during the mixing process is sensed and monitored by the gravity sensor arranged on the side wall of the separator. During the mixing and separation process, the rotating blades in the separator drive the lower sand and gravel mixture to rotate. The sand and gravel mixture will hit the side wall during the rotation process, thereby generating impact gravity. Since the separation of sand and gravel must be achieved during the mixing and rotating process, the sand and gravel will exist in different areas. As the separation process proceeds, the sensed impact force will gradually form a corresponding impact area. The first position area is the area where smaller particles of sand are rotated and hit, and the second position area is the area where larger particles of gravel are hit during the rotation process. The first sensing force set is the sum of the sensing forces for the areas where small particles of sand are hit. If the separation effect is good, the first sensing force set should be maintained within a uniform range. If the uniformity of the first sensing force set is poor, it indicates that the separation effect in the current area is uneven and there are different particle size ranges. When performing the first uniformity calculation, due to the differences in the particle morphology of the sand and the torque influence of the impact angle, there are differences. However, since they have common physical properties, the differences should be kept within a uniform range. Maintained within a certain range, so the reasonable range of sensing force should be considered when performing uniformity analysis, and data preprocessing is performed on the first sensing force set. The preprocessing can be a discreteness analysis of the first sensing force set, and the mean range of the data is obtained based on the discreteness analysis result, and the uniformity is calculated within the mean range. Similarly, the second sensing force set is the sum of the sensing forces collected in the second position area. Data analysis is performed on the second sensing force set to find the force range of the second position area, and the data in the second sensing force set that meets the force range is screened. The screened results are subjected to uniformity analysis. If the second uniformity meets the requirements, it indicates that the similarity of the particles in the area is high, otherwise it is low. If both the first uniformity and the second uniformity do not meet the requirements, and the overlapping range of the first sensing set and the second sensing set is large, it is judged that the current separation effect is not good, and the rotation speed needs to be increased to improve the separation effect. The first result is that the first uniformity and the second uniformity do not meet the second predetermined condition, wherein the first result includes multiple results such as the first uniformity and the second uniformity are not satisfied, one is satisfied, and / or the first sensing set and the second sensing set have a high degree of overlap. The second result is that the first uniformity and the second uniformity meet the second predetermined condition, which indicates that the current separation effect meets the requirements and no speed adjustment is required. The separation state is monitored in real time, and timely adjustments are made for separation effects that do not meet the requirements, avoiding rework due to poor separation and ensuring the technical effect of matching the separation machine operation parameter control with the separation effect.

[0073] Furthermore, the method comprises:

[0074] Step S910: obtaining device force information according to the first sensing force set and the second sensing force set;

[0075] Step S920: obtaining torsional strength information according to the torsion control strategy;

[0076] Step S930: input the equipment force information and torsional strength information into a loss prediction model;

[0077] Step S940 obtains a third output result of the loss prediction model, wherein the third output result includes a predicted loss result;

[0078] Step S950: When the predicted loss result exceeds the third preset condition, early warning information is obtained.

[0079] Specifically, in addition to the situation where the speed is insufficient to achieve the separation effect, there is also the situation where the speed is too fast and although the separation effect meets the requirements, there are energy consumption and wear of the equipment. In the case of the second result, that is, the first uniformity and the second uniformity both meet the requirements, the embodiment of the present application calculates the loss of the current equipment through the sensed gravity set combined with the torsional strength currently set in the torsional control strategy, and predicts the loss of the current equipment, such as the loss of the rotating impeller. The higher the speed, the greater the impact force of sand and gravel, which will cause the loss of the rotating impeller. The force information of the equipment, that is, the impact force sensed by the gravity sensor and the torsional strength information are analyzed and processed, and the impact force is calculated for the torsional strength information. According to the prediction, the predicted impact force is compared with the sensed force. If the sensed impact force is much greater than the predicted maximum impact force, it indicates that the current rotation speed is too large for the sand and gravel mixture being separated, or there are large particles in the sand and gravel mixture, which increase the sensed force and increase the wear of the equipment; if the difference between the predicted impact force and the sensed force is not large, it indicates that the requirements of the current operation separation are met and in line with expectations. The wear status is evaluated according to the exceeded impact force to obtain the predicted loss result, and it is determined whether the predicted loss result exceeds the preset requirements. If it exceeds the equipment loss requirements, an early warning is issued to remind that there is equipment wear in the current separator and corresponding adjustments need to be made. In order to improve the accuracy of the evaluation of the predicted loss results, the embodiment of the present application uses a neural network model for evaluation, calculates the centrifugal force based on the torsional strength information, and calculates the predicted force information based on the centrifugal force and the sand and gravel amount information; calculates the force difference based on the predicted force information and the equipment force information, and inputs the force difference and torsional strength information as input information into the loss prediction model. The loss prediction model is a neural network model in machine learning, which is obtained through training using multiple sets of training data. The multiple sets of training data all include force difference, torsional strength information, and identification information for identifying the loss results. The training process is essentially a supervised learning process. Each set of supervised data includes force difference, torsional strength information, and identification information for identifying the loss results. The force difference and torsional strength information are input into the neural network model. According to the identification information used to identify the loss results, the neural network model continuously corrects and adjusts itself until the output result obtained is consistent with the identification information, then the supervised learning of this set of data is terminated and the supervised learning of the next set of data is carried out; when the output information of the neural network model reaches a predetermined accuracy rate / reaches a convergence state, the supervised learning process ends. Through supervised learning of the neural network model, the neural network model can process the input information more accurately, and the output predicted loss results can be more reasonable and accurate, thereby achieving the technical effect of evaluating and warning of losses existing during the operation of the separator, and improving the calculation processing speed and the reliability of the prediction results.
