[0002] In mine production, crushers are widely used in ore crushing and processing. The crusher, also known as a rock crusher, is an important part of the entire mine production line. The efficient operation of the crusher is crucial to ensure the crushing effect and production efficiency of the ore. As one of the main equipment in the mine, it is responsible for crushing the raw large ore into the required particle size through mechanical force. It is usually driven by an electric motor and achieves ore crushing and classification through rotor or pressure plate crushing elements. The operation effect of the crusher directly affects the subsequent beneficiation, grinding and concentrate processes, so its stable operation state and accurate parameter control are crucial.

[0003] However, the current key parameters of the crusher cannot be accurately monitored and adjusted in real time. Due to the lack of real-time monitoring, the operating personnel cannot accurately grasp the working state of the crusher, and cannot adjust the parameters in time to ensure the best crushing effect and production efficiency.

DETAILED DESCRIPTION

[0078] The following Figures 1-3 Further details of the present application will be described in the embodiments of the present application, and the terms used in the embodiments of the present application are only for the purpose of describing specific embodiments, and are not intended to be limiting.

[0079] The crusher is responsible for crushing the original large ore into the required particle size by mechanical force, usually driven by an electric motor, and the crushing and classification of the ore are realized through the crushing elements such as rotor or pressure plate. The operation effect of the crusher directly affects the subsequent beneficiation, grinding and concentrate process, so its stable operation state and accurate parameter control are crucial. However, there is a significant problem at present, that is, the crusher cannot be accurately monitored and adjusted due to too many operation parameters and technical problems to be considered. This includes important parameters such as discharge particle size, rotating speed, pressure, current of the crusher. Due to the lack of real-time monitoring, the operating personnel cannot accurately grasp the working state of the crusher, and cannot adjust the parameters in time to ensure the best crushing effect and production efficiency. More seriously, if some parameters exceed the safe range, it may cause equipment overload, damage or even safety accidents, which has a significant impact on production.

[0080] The present application realizes accurate monitoring and dynamic adjustment of key parameters of the crusher by introducing an advanced monitoring and control system. Such technical means not only can improve the operation stability and safety of the crusher, but also can maximize the crushing effect and production efficiency, thereby bringing significant technical progress and economic benefits to the mine production.

[0081] With reference Figure 1 The intelligent control method of the mine crusher according to the present application specifically comprises:

[0082] Step S1: acquiring historical parameters of component adjustment parameters, and constructing a component adjustment model according to the historical parameters of the component adjustment parameters;

[0083] Step S2: acquiring liner thickness information and moving cone position information, inputting the liner thickness information and the moving cone position information into the component adjustment model to obtain updated moving cone position information;

[0084] Step S3: performing instruction matching according to the updated moving cone position information to obtain position adjustment instructions for adjusting the position of the moving cone;

[0085] Step S4: acquiring current material information, and matching the current material information with pre-set moving cone rotating speed range information to obtain first updated moving cone rotating speed information;

[0086] Step S5: According to the first moving cone update speed information, the instruction matching is performed to obtain the speed adjustment instruction for adjusting the moving cone speed.

[0087] Specifically, the crusher delivers the stone to be crushed to the feeding device by a conveying belt or the like, and the feeding device delivers the stone to the inside of the crusher as the feeding port of the crusher. The inside of the crusher is specifically composed of a movable cone located in the middle part and being adjustable in lifting and a liner plate installed on the inclined inner wall of the crusher. A stone crushing channel is formed between the side wall of the movable cone and the liner plate, and the size of the stone crushing channel needs to be adjusted according to different materials. The stone crushing channel is used to limit the passage of oversized stones, and the stones located in the stone crushing channel are crushed by the friction between the movable cone and the liner plate, so that the crushed stones fall to the discharge port below, and then the discharged stones are transported away by a conveying device. In this operation process, the method of the application is implemented by the intelligent control device of the stone crusher. The control device obtains data by connecting a plurality of sensors or detection devices inside and outside the control device.

[0088] The application obtains the historical parameters of the component adjustment parameters in the operation process of the crusher, and constructs a component adjustment model based on the historical parameters of the component adjustment parameters. The historical parameters of the component adjustment parameters are the corresponding data of the movable cone and the liner plate in the operation process of the crusher. The obtained liner plate thickness information and movable cone position information are input into the component adjustment model for analysis to obtain suitable movable cone update position information, which is output to the external movable cone control system, so that the movable cone is adjusted to a suitable position, so that the movable cone can cooperate with the liner plate worn to a certain extent to always crush the stone to a suitable size range. According to the current material information, the movable cone speed range information is matched to obtain the first movable cone update speed information, which is output to the external movable cone control system, so that the movable cone performs the crushing work at a suitable speed, adjusts the crusher parameters in real time, and improves the working efficiency and reliability of the crusher.

[0089] As one of the embodiments, the specific steps of obtaining the historical parameters of the component adjustment parameters and constructing the component adjustment model based on the historical parameters of the component adjustment parameters are as follows: analyzing the historical liner plate thickness and the historical movable cone position in the historical parameters of the component adjustment parameters to obtain a first adjustment change relationship value; and obtaining the component adjustment model according to the first adjustment change relationship value, the historical liner plate thickness and the historical movable cone position.

[0090] Specifically, the historical liner thickness and the historical cone position are obtained by corresponding sensors, respectively, such as the cone position data, and the control device of the application records one cone position data as one of the historical cone position data each time the control device sends instruction information to the cone control device. The liner thickness is detected and obtained by the corresponding sensor every interval, and the liner thickness data obtained by the control device of the application is the historical liner thickness. The liner thickness data and the cone position data are one-to-one corresponding through time information, that is, each thickness data in the historical liner thickness corresponds to the cone position data in the historical cone position. In the embodiment of the application, the cone position data is specifically the height data of the cone

[0091] Because the recording methods of the cone position data and the liner thickness data are different, there are usually more liner thickness data than cone position data, so that the data cannot be corresponding. In the embodiment of the application, the time point data is used to classify which one of the redundant liner thickness data corresponds to the cone position data, for example, the cone position data changes at 12:30:10 on July 10, 2020, and the next change time is at 12:32:10 on July 10, 2020, and the interval acquisition time of the liner thickness data is 30 seconds, so the time points of the liner thickness data from 12:29:30 on July 10, 2020 are 12:29:30, 12:30:00, 12:30:30, 12:31:00, 12:31:30, 12:32:00, and 12:32:30. The time points of the liner thickness data 12:29:30 and 12:30:00 correspond to the cone position data that changes once before 12:30:10, the time points of the liner thickness data 12:30:30, 12:31:00, 12:31:30, and 12:32:00 correspond to the cone position data that changes at 12:30:10, and the time point of the liner thickness data 12:32:30 corresponds to the cone position data that changes at 12:32:10.

[0092] After obtaining the historical liner thickness and the historical cone position, the embodiment of the application constructs a liner thickness and cone height relationship by the liner thickness data in every two historical liner thicknesses and the cone position data in the historical cone position, which is specifically a linear relationship, calculates a plurality of adjustment parameters k, and then calculates the average value of the plurality of adjustment parameters k to obtain an initial adjustment parameter, that is, a first adjustment change relationship value, and constructs a component adjustment model through the first adjustment change relationship value. The model and the above linear relationship are the same concept, which is specifically: H=H0+k(T0-T).

[0093] H = H0+ k (T - T0), wherein H is the moving cone updated position information, k is the first adjustment change relationship value, H0is the last moving cone position data, T0is the liner thickness data corresponding to H0, and T is the next liner thickness data corresponding to T0. The feasibility of the component adjustment model is re-verified through the historical parameters of the component adjustment parameters, and a final component adjustment model is obtained, thereby providing a basis for automatically adjusting the moving cone position according to the change in the liner thickness.

[0094] As one of the embodiments, the liner thickness information and the real-time position information of the moving cone are obtained, and the liner thickness information and the moving cone position information are input into the component adjustment model. Specifically, the liner thickness information and the moving cone position information obtained at a last preset time are obtained, wherein the liner thickness information includes liner first thickness data obtained at a last preset time and liner second thickness data obtained in real time, the liner first thickness data, the liner second thickness data, and the moving cone position information are input into the component adjustment model, and moving cone updated position information is obtained.

[0095] Specifically, in the embodiment of the application, the liner first thickness data is obtained at a last preset time, i.e., at a last time, and the liner first thickness data corresponds to the moving cone position information. The liner second thickness data is data at a current time. The H moving cone updated position information is obtained by inputting the liner first thickness data, the liner second thickness data, and the moving cone position information into the component adjustment model. The control device of the application outputs a corresponding control instruction to the moving cone control device through the moving cone updated position information, so that the moving cone control device adjusts the moving cone to a suitable height according to the instruction. In the case where the liner thickness is consumed by grinding, the height of the moving cone is usually adjusted to be lowered, so that the worn liner and the moving cone still remain within a suitable range, thereby realizing real-time adjustment of the crusher parameters, keeping the operation of each device of the crusher normal, reducing human intervention, and improving the working efficiency and reliability of the crusher.

[0096] As one of the embodiments, the method further includes: in the case where the moving cone updated position information is obtained, a change relationship optimization model is constructed according to the liner second thickness data and the moving cone updated position information, a second adjustment change relationship value is obtained through the change relationship optimization model, and the first adjustment change relationship value of the component adjustment model is replaced according to the second adjustment change relationship value.

[0097] Specifically, the embodiment of the application is usually executed after the moving cone updated position information is obtained. The liner second thickness data and the moving cone updated position information are corresponding data, and the change relationship optimization model is constructed through the real-time corresponding data. The specific steps of constructing the change relationship optimization model are as follows:

[0098] First, an optimization objective needs to be obtained, for example, minimizing the error between the actual measurement data and the prediction of the straight line model, usually using mean square error MSE or other loss function to define, so that the prediction result of the adjustment parameter and the moving cone update position information is as close as possible to the actual data. In the case of obtaining the second thickness data of the liner and the moving cone update position information, the mean square error is calculated according to the last liner and thickness data obtained and the second thickness data of the liner and the moving cone update position information.

[0099] Then, an optimization algorithm is selected, for example, gradient descent, to adjust the value of the adjustment parameter k to minimize the loss function. In the gradient descent method, the gradient of the error with respect to the adjustment parameter can be calculated, and the value of the adjustment parameter can be adjusted in the negative gradient direction to gradually reduce the error.

[0100] The optimized adjustment parameter value is fed back to the control system or the adjusting device in real time, specifically, as the second adjustment change relationship value to replace the first adjustment change relationship value of the component adjustment model, to adjust the control of the moving cone. This feedback control mechanism can periodically or as needed adjust the value of the adjustment parameter to adapt to different working conditions or environmental changes. And according to manual or automatic periodic verification and adjustment of the optimization method, it is ensured that the adjustment strategy of the adjustment parameter is still effective, and necessary modification and improvement are made according to the actual situation.

[0101] It should be noted that the data obtained by the present application has sufficient accuracy and real-time performance, which improves the effect of optimizing the adjustment parameter. When designing the control system, the uncertainty and stability requirements of the environment are considered, so that the real-time adjusted adjustment parameter value can maintain reasonable stability and robustness under various working conditions. Through the real-time optimization of the adjustment parameter value in the embodiments of the present application, the straight line model can maintain the optimal adjustment state under different working conditions, so as to more accurately predict and control the change of the moving cone height with the liner thickness.

[0102] The specific implementation content of the implementation scheme provided by the embodiments of the present application is as follows:

[0103] First, the optimization objective is determined by adjusting the adjustment parameter value to make the prediction value of the straight line model, i.e., the component adjustment model, as close as possible to the actual measured liner thickness height data. In order to quantify the difference between the model prediction and the actual data, a loss function needs to be selected. The mean square error MSE is selected in the embodiments of the present application, and the method for calculating the mean square error MSE is

[0104] Wherein, H i is the moving cone height data of the i-th vehicle, i.e., the moving cone update position information, T i is the second thickness data of the liner corresponding to the moving cone update position information, T 0iis the first thickness data of the last liner, n is the sample size. After obtaining the value of the mean square error, an optimization algorithm such as gradient descent is selected to adjust the value of the adjustment parameter to minimize the loss function.

[0105] Specifically, the gradient of the loss function with respect to the adjustment parameter is calculated, and the value of the adjustment parameter k is updated in the opposite direction of the gradient, specifically: Where α is the learning rate, a constant that controls the step size of each update, that is, the magnitude of each parameter update, the size of the adjustment parameter change in each iteration;

[0106] k is the state before and after updating, k1 is the updated k value, and k2 is the k value before updating;

[0107] MSE is the mean square error, the abbreviation of Mean Squared Error, which is a method to measure the difference between the predicted value and the actual observed value. In this formula, MSE is a function of the adjustment parameter k, and the error is minimized by adjusting the adjustment parameter;

[0108] is the symbol representing the partial derivative in mathematics, which is used to describe the rate of change of a function when a certain variable changes while other variables remain unchanged; is the loss function, specifically the partial derivative of the mean square error MSE with respect to the adjustment parameter k, so that the rate of change or gradient direction of the loss function MSE when the adjustment parameter k changes is known. In the gradient descent algorithm, the gradient information is used to update the value of the adjustment parameter to reduce the value of the loss function.

[0109] After obtaining the updated k value, that is, the second adjustment change relationship value, the optimized adjustment parameter k value is fed back to the control system in real time to adjust the control of the moving cone height. Finally, the effectiveness of the optimization method is verified regularly, and the model or optimization strategy is adjusted according to the actual situation to ensure system stability and superior performance.

[0110] Adjusting the adjustment parameter k in real time to optimize the component adjustment model can dynamically adjust the model according to the actual liner thickness data, making the prediction ability of the model more accurate and precise. And the system can capture the changes of the liner thickness and the height of the moving cone position in time and make corresponding adjustments to improve the accuracy and stability under different working conditions. By minimizing the error between the predicted value and the actual measured value, waste and adjustment time in the production process can be reduced, thereby improving production efficiency. The adjustment parameter k value can be adjusted according to the changes of the liner thickness in the actual production environment, making the system more adaptable and flexible, suitable for different production conditions and requirements. By continuously collecting real-time data and optimizing the adjustment parameter k value, the system can make more accurate decisions based on actual data, avoiding reliance on static or outdated models. Regularly verify the effectiveness of the optimization method and adjust the adjustment parameter k value and optimization strategy according to feedback to help the system continuously improve and optimize and maintain optimal performance. In summary, by adjusting the adjustment parameter k in real time, the system can be more intelligent and responsive, improving the efficiency and accuracy of the production process. The effects of the embodiments of the present application are embodied in:

[0111] Optimized performance, which is reflected in the adjustment of the adjustment parameter k, which can help optimize the operation of the crusher. For example, the crusher may have different working conditions, such as different raw materials, different environmental conditions, by adjusting the adjustment parameter k, the crusher can have higher processing capacity or better crushing effect under different working conditions;

[0112] Energy saving, which is reflected in the reasonable adjustment of the adjustment parameter k, which can help save energy and resources. For example, in some cases, adjusting the parameter can reduce the energy consumption of the machine, improve the energy utilization efficiency, and thus reduce the operating cost;

[0113] Strong adaptability, which is reflected in the real-time adjustment, the crusher can better adapt to changes in the running environment. For example, in the face of changes in the particle size requirements of different raw materials or changes in the load, the adjustment parameter can make the crusher maintain stable performance in these changes;

[0114] Reducing the failure rate, which is reflected in the timely adjustment of the parameter, which can reduce the failure rate of the equipment, because it can maintain optimal state operation, reducing the risk of mechanical wear and overload;

[0115] Improving product quality, which is reflected in that for part of the production process, the parameter adjustment of the crusher may directly affect the product quality. By optimizing the adjustment parameter k, the particle size, uniformity or other quality indicators of the product can be controlled to ensure that the product meets the specification requirements.

[0116] As one of the implementation manners, it also includes:

[0117] According to the matching of the current material information and the pre-set working current range information, the working current reference range is obtained;

[0118] obtaining real-time main motor current information, judging whether the real-time main motor current information exceeds a working current reference range, and obtaining dynamic cone position adjustment information in the case that the real-time main motor current information exceeds the working current reference range;

[0119] performing instruction matching according to the dynamic cone updated position information to obtain position adjustment instructions for adjusting the position of the dynamic cone.

[0120] Specifically, the embodiment of the application is used to detect that hard objects such as iron blocks are mixed in the stone during the crushing process, which causes the real-time main motor current to rise to an abnormal value. Generally, the current change needs to be detected first, and then the current change condition is compared with the working current range information to judge whether the current is out of range, that is, the current is abnormal. Then, the position of the dynamic cone is adjusted according to the range exceeding the position of the dynamic cone, that is, the dynamic cone position adjustment information is obtained. The control device of the application sends the dynamic cone position adjustment information to the main motor control system, so that the main motor control system sends instructions to control the position of the dynamic cone. The specific steps are as follows:

[0121] First, according to the characteristics of the material and the preset working parameters, a reference range of working current, that is, working current range information, is set. The working current range information is determined based on the type, particle size, density and other factors of the material, so that the equipment can run in a safe and efficient working condition. The system obtains the current information of the main motor in real time. The main motor is usually responsible for driving the crushing process of the crushing chamber in the equipment, specifically providing rotating force for the dynamic cone. The change of current reflects the current working load and running state of the main motor. It is judged whether the real-time current exceeds the working current reference range. The real-time current information of the main motor is compared with the preset working current range. If the real-time current exceeds the set range, it indicates that the equipment is facing overload or other abnormal conditions, and measures need to be taken to adjust. In the case that the real-time current exceeds the working range, the system triggers the process of obtaining the dynamic cone position adjustment information. The dynamic cone is usually used to adjust the discharge of the material in the crushing chamber and the size of the crushed stone. Its position adjustment can affect the crushing efficiency and current load. Adjusting the position of the dynamic cone involves communicating and connecting the hydraulic adjustment to control the high and low positions, so as to ensure that the equipment returns to a safe and efficient working state. The embodiment is a feedback control system. The system adjusts the position of the dynamic cone or restores the stable running state of the equipment through other control means according to the change of the real-time current. This includes monitoring and timely adjusting the working parameters to reduce the overload of the equipment or other potential problems, while maximizing the service life and efficiency of the equipment.

[0122] As one of the implementation manners, it further comprises:

[0123] matching the current material information with the preset dynamic cone pressure range information to obtain a dynamic cone pressure reference range;

[0124] obtaining real-time dynamic cone pressure information, determining whether the real-time dynamic cone pressure information exceeds a dynamic cone pressure reference range, and obtaining dynamic cone position adjustment information in the case that the real-time dynamic cone pressure information exceeds the dynamic cone pressure reference range;

[0125] performing instruction matching according to the dynamic cone updated position information to obtain position adjustment instructions for adjusting the dynamic cone position.

[0126] Specifically, the embodiment of the present application is used to detect that hard objects such as iron blocks are mixed in the stone during the crushing process, which causes the real-time dynamic cone pressure to rise to an abnormal value. Generally, the real-time dynamic cone pressure information needs to be detected first, and then the dynamic cone pressure is compared with the compared dynamic cone pressure reference range to determine whether the current pressure exceeds the range, i.e., the current pressure is abnormal. Then, the dynamic cone position is adjusted according to the exceeded range, i.e., the dynamic cone position adjustment information is obtained. The control device of the present application sends the dynamic cone position adjustment information to the main motor control system, so that the main motor control system sends instructions to control the position of the dynamic cone. The specific steps are as follows:

[0127] First, a dynamic cone pressure reference range is preset according to the type and particle size of the material and the design of the equipment. This range is to ensure that the equipment operates in the most effective and safe state, and to reduce the situation that the performance of the equipment is reduced or damaged due to excessively high or low dynamic cone pressure. Real-time dynamic cone pressure information is obtained, and the system monitors and obtains the pressure information of the dynamic cone in real time. The dynamic cone is usually used to adjust the discharge of materials and the particle size of crushed stone in the crushing chamber, and the change of its pressure reflects the working state and load of the dynamic cone when processing stone. It is determined whether the dynamic cone pressure exceeds the reference range. The obtained real-time dynamic cone pressure information is compared with the preset dynamic cone pressure reference range. If the real-time pressure exceeds the set safe range, it indicates that the equipment encounters an abnormal situation, and measures need to be taken to adjust. When the real-time dynamic cone pressure exceeds the preset range, the system triggers the process of obtaining the dynamic cone position adjustment information. Adjusting the position of the dynamic cone can change the flow and discharge mode of the materials in the crushing chamber to reduce the pressure of the dynamic cone and readjust the working state of the equipment. The present embodiment is an automatic feedback system that ensures the stability and efficiency of the equipment under various working conditions. The system can adjust the position of the dynamic cone, optimize the material feeding method, or adjust other process parameters to cope with the abnormal dynamic cone pressure caused by hard objects in the stone.

[0128] In the face of the challenge of hard objects such as iron blocks mixed in the stone during the crushing process, the system monitors the dynamic cone pressure in real time and adjusts dynamically, so that the equipment can process materials in a safe and efficient operating state, and maximize the service life and processing efficiency of the equipment.

[0129] As one of the implementation manners, it further includes:

[0130] According to the matching of the second liner thickness data and the pre-set liner thickness range information, a thickness state is obtained, and in the case that the thickness state is abnormal, second dynamic cone update speed information is obtained;

[0131] The first dynamic cone update speed information is replaced according to the second dynamic cone update speed information.

[0132] Specifically, in the embodiment of the present application, the system obtains second liner thickness data. The liner is usually used to protect the internal components of the machine from material wear or impact. The system compares the second liner thickness data with the pre-set liner thickness range. This range is determined in advance according to the design and operating conditions of the equipment, and is used to determine whether the liner is in a normal working state.

[0133] According to the matching result, the system will determine the thickness state of the liner, which is set with a certain classification. In the embodiment of the present application, four levels are set, such as normal, good, thin, and too thin, and the levels gradually change from good to bad. If the thickness of the liner is determined to be too thin, it means that the liner has been worn to the extent that affects the operation or safety of the equipment.

[0134] When the thickness state of the liner is identified as too thin, the system will generate second dynamic cone update speed information according to the pre-set algorithm or logic. The second dynamic cone update speed information has the same effect as the first dynamic cone update speed information, both of which are sent to the dynamic cone control system to be converted into instructions, thereby adjusting the speed of the dynamic cone. The dynamic cone is usually one of the key components for adjusting the material handling performance and efficiency of the equipment. The update speed information is the rotational speed of the second dynamic cone to adapt to the additional wear or other effects caused by the too thin liner. Among them, the speed is usually set to change from fast to slow, so as to reduce the heating of the liner and thus reduce the wear.

[0135] The embodiment of the present application constitutes a feedback and adjustment system, which monitors the thickness of the liner and adjusts the speed of the dynamic cone as needed, so that the equipment improves the ability to safely operate and efficiently handle materials under various working conditions, adjusts the parameters of the crusher in real time, and improves the working efficiency and reliability of the crusher.

[0136] As one of the implementation manners, it further includes:

[0137] Obtain hydraulic temperature information, and match the hydraulic temperature information with pre-set hydraulic temperature range information to obtain a hydraulic temperature state. In the case that the hydraulic temperature state is overheated, third dynamic cone update speed information is obtained;

[0138] The first dynamic cone update speed information is replaced according to the third dynamic cone update speed information.

[0139] obtain lubrication temperature information, match the lubrication temperature information with pre-set lubrication temperature range information to obtain a lubrication temperature state, and obtain fourth movable cone updated rotating speed information in a case where the lubrication temperature state is that a lubrication parameter is overheated;

[0140] replace the first movable cone updated rotating speed information with the fourth movable cone updated rotating speed information.

[0141] Specifically, in the embodiments of the present application, the parameters of the hydraulic system and the lubrication system are monitored and adjusted.

[0142] The hydraulic system of the crusher is one of the key parts, which is responsible for providing power for the movable cone adjustment position and controlling various operations. The hydraulic system usually includes hydraulic pumps, hydraulic cylinders, hydraulic valves and other components, which are used to drive the adjustment of the movable cone, the start and stop of the equipment and other important functions. Among them, the hydraulic pump is responsible for sucking hydraulic oil from the oil tank and delivering it to each component in the system through pressure; the hydraulic cylinder is used to realize the motion control of the movable cone and the crushing mechanism, such as adjusting the position of the movable cone or applying crushing force. The hydraulic valve controls the flow direction, pressure and flow of hydraulic oil in the hydraulic system to ensure the coordinated operation of each executing component.

[0143] The role of the lubrication system in the crusher is to reduce friction and wear, thereby prolonging the service life of the equipment and improving the working efficiency. Among them, the lubricating oil is used to lubricate each moving part of the crusher to reduce friction and heat. The lubrication pump is responsible for delivering lubricating oil from the oil tank to the parts that need to be lubricated to ensure sufficient supply of lubricating oil. The lubrication pipeline and nozzle accurately deliver lubricating oil to the key parts of the crusher, such as the movable cone bearing and gear, to ensure the lubrication effect during high load and high speed operation.

[0144] The above two systems are related to the generation of heat due to the execution steps of the work, so that the oil temperature rises, affecting the normal work of the system or the internal structure of the crusher, and increasing the risk of damage and durability of the crusher during the working process.

[0145] Therefore, it is necessary to obtain the relevant information of the hydraulic temperature and the lubrication temperature respectively, and analyze the steps of obtaining the corresponding third movable cone updated rotating speed information and the fourth movable cone updated rotating speed information. Among them, the step of obtaining the third movable cone updated rotating speed information:

[0146] First, obtain the hydraulic temperature information. The control device system of the embodiments of the present application monitors and obtains the temperature data of the hydraulic system through an external sensor. The embodiments of the present application set that the temperature sensor of the hydraulic system collects data every certain time, for example, every minute.

[0147] Matching the hydraulic temperature information with the preset range, comparing the real-time acquired hydraulic temperature information with the preset hydraulic temperature range to determine the state of the hydraulic temperature, the preset hydraulic temperature range is 20-80 degrees Celsius, and sub-ranges within the range and the states of the sub-ranges are set;

[0148] Determining the hydraulic temperature state, according to the comparison result, if the hydraulic temperature state shows overheating, the system generates control information of the third dynamic cone update rotating speed according to the preset algorithm or logic, for example, if the real-time hydraulic temperature is 25 degrees Celsius, the state is normal, if the real-time hydraulic temperature is 85 degrees Celsius, the state is overheating, and if the real-time hydraulic temperature is 60 degrees Celsius, the state is normal;

[0149] Applying the third dynamic cone update rotating speed information: applying the calculated third dynamic cone update rotating speed information to the control system of the equipment to adjust the operating speed of the first dynamic cone to cope with the possible impact of the overheating of the hydraulic system, if the hydraulic temperature state shows overheating, for example, more than 80 degrees Celsius, the system generates control information of the third dynamic cone update rotating speed according to the preset algorithm to adjust the operating speed of the dynamic cone.

[0150] The steps of acquiring the fourth dynamic cone update rotating speed information are:

[0151] Acquiring lubrication temperature information, the system monitors and acquires the temperature data of the lubrication system through a sensor, and the temperature sensor of the lubrication system collects data every certain time, for example, every minute;

[0152] Matching the lubrication temperature information with the preset range, comparing the real-time acquired lubrication temperature information with the preset lubrication temperature range to determine the state of the lubrication temperature, the preset lubrication temperature range is 40-100 degrees Celsius, and sub-ranges within the range and the states of the sub-ranges are set;

[0153] Determining the lubrication temperature state, according to the comparison result, if the lubrication temperature state shows overheating, the system generates control information of the fourth dynamic cone update rotating speed according to the preset algorithm or logic, for example, if the real-time lubrication temperature is 45 degrees Celsius, the state is normal, if the real-time lubrication temperature is 110 degrees Celsius, the state is overheating, and if the real-time lubrication temperature is 70 degrees Celsius, the state is normal;

[0154] Applying the fourth dynamic cone update rotating speed information: applying the calculated fourth dynamic cone update rotating speed information to the control system of the equipment to adjust the operating speed of the first dynamic cone to cope with the possible impact of the overheating of the lubrication system, if the lubrication temperature state shows overheating, for example, more than 100 degrees Celsius, the system generates control information of the fourth dynamic cone update rotating speed according to the preset algorithm to adjust the operating speed of the dynamic cone.

[0155] These steps enable the system to adjust the speed of the moving cone in time when the temperature of the hydraulic or lubrication system is abnormal, thereby ensuring the safe operation and performance optimization of the crusher equipment.

[0156] As one of the embodiments, it further comprises:

[0157] Obtaining the material level height information, matching the material level height information with the pre-set material level height range information to obtain the material level height state, and obtaining the fifth moving cone updated speed information in the case that the material level height state is too high;

[0158] Replacing the first moving cone updated speed information with the fifth moving cone updated speed information.

[0159] Specifically, the embodiment of the present application is aimed at the discharging condition in the crusher. During the operation of the crusher, the material level height is a key operating parameter. The material level height refers to the material accumulation height inside the crusher or at the discharge port. A suitable material level height can ensure the crushing efficiency and the stability of the discharge, and an excessively high or low material level height may lead to the decline of the production efficiency or the abnormal operation of the equipment.

[0160] The material level height data is monitored and obtained in real time through the material level sensor installed at the discharge port of the crusher or other key positions. The real-time obtained material level height information is compared and matched with the pre-set material level height range. For example, the pre-set reasonable material level height range is 20-40 cm. If the real-time material level height is 25 cm, the state is normal, and if the real-time material level height is 45 cm, the state is too high. If the material level height state shows that it is too high, the system will generate the fifth moving cone updated speed information. The material level height information is used to judge and adjust the equipment operation state, so as to improve the efficiency of production and the safety of the equipment.
