[0023] Figure 1A flow chart of a method for intelligent power control of mining equipment according to an embodiment of the present invention is exemplarily shown, the method comprising: step S101, obtaining the power of the mining equipment at the start time of the current control cycle, and obtaining multiple current data of the mining equipment and environmental data of the mining area at multiple times of the current control cycle, wherein the mining equipment is an electrically driven device including multiple power-consuming devices, and the environmental data includes temperature data, humidity data and harmful gas concentration data; step S102, determining an overload score according to the current data; step S103, determining a safety score according to the environmental data; step S104, obtaining the mining equipment at the end time of the current control cycle; amount and the remaining target mining amount; step S105, determining a completion score according to the mining amount and the remaining target mining amount; step S106, determining whether the power of the mining equipment in the next control cycle needs to be adjusted according to the overload score, the safety score and the completion score; step S107, if the power of the mining equipment in the next control cycle needs to be adjusted, determining the power of the adjusted mining equipment according to the power of the mining equipment in the current control cycle, the current data, the environmental data, the mining amount and the remaining target mining amount; step S108, at the start time of the next control cycle, setting the power of the mining equipment to the power of the adjusted mining equipment.

[0024] According to the mining equipment power intelligent control method of the embodiment of the present invention, by real-time monitoring of current data, it is possible to quickly identify whether the mining equipment is overloaded, thereby reducing mechanical wear and failure caused by overload. By evaluating the safety score through environmental data, it is possible to timely discover operational hazards, slow down the mining speed, reduce the accident rate, and ensure the safety of mining equipment. By monitoring the mining volume and the remaining target mining volume, the production progress and completion status can be understood in real time. The power of the mining equipment is adjusted based on the changes in the above various factors, which improves the automation and intelligence level of the mining equipment, reduces the need for manual intervention, and thus improves the efficiency of the mining equipment.

[0025] According to one embodiment of the present invention, in step S101, each control cycle can be set to 20 minutes, 30 minutes, etc., and the interval between adjacent moments can be set to 1 minute, 2 minutes, etc., which is not limited by the present invention. At the beginning of the current control cycle, the power of the mining equipment is measured and recorded. The mining equipment includes a plurality of power-consuming devices, that is, inside the mining equipment, there are a plurality of subsystems or components that rely on electricity to operate, such as electric motors, conveyor belts, pumps and other electrical equipment. At multiple moments of the current control cycle, the current data of the mining equipment is regularly recorded by a current sensor. The current data reflects the power usage of the mining equipment at different time points, which can help determine the load state of the mining equipment. At the same time, a variety of sensors are used to collect environmental data related to the mining area. The temperature data is used to measure the temperature of the mining area and understand the changes in environmental heat. The humidity data is used to record the humidity level in the air, which affects the mining equipment and the safety of operations. The harmful gas concentration data is used to monitor the concentration of harmful gases (such as methane, carbon monoxide, etc.) in the mining area to reflect the safety of the working environment.

[0026] According to an embodiment of the present invention, in step S102, the collected current data is analyzed to determine an overload score so as to evaluate the load status of the mining equipment in the entire control cycle.

[0027] According to an embodiment of the present invention, determining the overload score according to the current data includes: determining the overload score according to formula (1): ,

[0028] (1)

[0029] in, is the current data of the ith power-consuming device at the kth moment of the current control cycle, is the current data threshold of the i-th power consuming device, is the number of power consuming devices, is the number of moments in the control cycle, i≤ , k≤ , and i, k, and All are positive integers, and if is a conditional function.

[0030] According to one embodiment of the present invention, in formula (1), When the current data of the i-th power-consuming device at the k-th moment in the current control cycle is greater than or equal to the current data threshold of the i-th power-consuming device, the conditional function value is 1, indicating that the power-consuming device is in an overloaded state at this moment; otherwise, the conditional function value is 0, indicating that the power-consuming device is not overloaded at this moment. The ratio of the number of overloaded power-consuming devices at multiple moments that meet the conditions to the total number of power-consuming devices at multiple moments is the overload score. The overload score reflects the overall overload situation of the power-consuming devices in the entire control cycle. The higher the overload score, the more power-consuming devices are in an overloaded working state, and the more the mining equipment power needs to be adjusted.

[0031] In this way, the overload score can be determined based on the comparison results of the current data and the current data threshold, and the load status of the mining equipment can be quantitatively evaluated, which improves the accuracy and objectivity of the overload score, thereby optimizing the operation of the mining equipment, reducing downtime and maintenance costs caused by equipment failure, and improving the utilization efficiency of the mining equipment.

[0032] According to one embodiment of the present invention, in step S103, the environmental data includes temperature data, humidity data and harmful gas concentration data, which are related to the mining area and reflect the safety issues of the mining area environment, thereby determining the safety score.

[0033] According to one embodiment of the present invention, step S103 includes: obtaining the temperature average value and the humidity average value of the current control cycle based on the temperature data and the humidity data; obtaining the concentration threshold of each harmful gas; and determining the safety score based on the temperature data, the humidity data, the temperature average value, the humidity average value, the harmful gas concentration data and the harmful gas concentration threshold.

[0034] According to one embodiment of the present invention, the collected temperature data is averaged to obtain the average temperature value of the current control cycle. Similarly, the humidity data is averaged to obtain the average humidity value. The concentration threshold of each harmful gas is obtained based on industry standards or regulatory requirements. Changes in environmental factors can affect the operating efficiency and safety of mining equipment. Therefore, the safety of the working environment is evaluated based on the safety score.

[0035] According to an embodiment of the present invention, determining a safety score according to the temperature data, the humidity data, the temperature average value, the humidity average value, the harmful gas concentration data and the harmful gas concentration threshold value includes: determining the safety score according to formula (2): ,

[0036] (2)

[0037] in, is the temperature data at the kth moment of the current control cycle, is the preset temperature, is the average temperature, is the humidity data at the kth moment of the current control cycle, To preset humidity, is the average humidity value, is the harmful gas concentration data of the jth harmful gas at the kth moment in the current control cycle, is the harmful gas concentration threshold of the jth harmful gas, , and is the preset weight, is the number of moments in the control cycle, is the amount of harmful gases, k≤ , j≤ , and k, j, and All are positive integers, if is a conditional function, max is a maximum value function, and min is a minimum value function.

[0038] According to one embodiment of the present invention, in formula (2), It is the relative difference between the temperature data and the preset temperature at the kth moment of the current control cycle. The larger the relative difference, the greater the difference between the temperature data and the preset temperature, and the worse the temperature condition in the mining area. The relative difference is averaged to obtain the temperature deviation degree at all moments. It is the ratio of the difference between the maximum and minimum values ​​of the temperature data at multiple moments of the current control cycle to the average temperature value, that is, the relative difference between the maximum and minimum values ​​of the temperature data at multiple moments of the current control cycle. The larger the relative difference, the greater the degree of temperature change in the current control cycle, and the worse the temperature condition in the mining area. The severity of the temperature condition in the mining area can be obtained by multiplying the temperature deviation degree at all moments by the relative difference between the maximum and minimum values ​​of the temperature data at multiple moments of the current control cycle. It is the relative difference between the humidity data at the kth moment of the current control cycle and the preset humidity. The larger the relative difference, the greater the difference between the humidity data and the preset humidity, and the worse the humidity situation in the mining area. The relative difference is averaged to obtain the humidity deviation degree at all moments. It is the ratio of the difference between the maximum and minimum values ​​of the humidity data at multiple moments in the current control cycle to the average value of humidity, that is, the relative difference between the maximum and minimum values ​​of the humidity data at multiple moments in the current control cycle. The larger the relative difference, the greater the change in humidity in the current control cycle, and the worse the humidity situation in the mining area. The severity of the humidity situation in the mining area can be obtained by multiplying the humidity deviation degree at all moments by the relative difference between the maximum and minimum values ​​of the humidity data at multiple moments in the current control cycle. When the harmful gas concentration data of the jth harmful gas at the kth moment of the current control cycle is greater than or equal to the harmful gas concentration threshold of the jth harmful gas, the conditional function value is 1, otherwise, the conditional function value is 0. The conditional functions corresponding to the harmful gas concentration data of multiple harmful gases at multiple moments of the current control cycle are averaged to obtain the concentration severity of multiple harmful gases at all moments. The weighted sum of the severity of the temperature conditions, the severity of the humidity conditions, and the severity of the harmful gas concentration in the above-mentioned mining area can be obtained. The larger the result, the more unsafe the mining area environment. Subtracting the result from 1 is the safety score. The larger the safety score, the safer the mining area environment.

[0039] In this way, the safety score can be determined based on the severity of the environment in the mining area, and the mining area environment can be evaluated from three aspects: temperature, humidity and harmful gas concentration. This improves the comprehensiveness, objectivity and accuracy of the safety score, and can promptly detect potential safety hazards and adjust the power of mining equipment accordingly, thereby effectively preventing accidents and ensuring the safety of mining equipment.

[0040] According to one embodiment of the present invention, in step S104, the mining volume is the total amount of mineral resources actually mined at the end of the current control cycle. The remaining target mining volume is equal to the entire target mining volume, minus the mining volume completed in the historical control cycle and the current control cycle. For example, the entire target mining volume is 100 tons, the mining volume completed in the historical control cycle is 50 tons, and the mining volume completed in the current control cycle is 2 tons, then the remaining target mining volume is 100-50-2=48 tons. Among them, the target mining volume is the mining volume of the task indicator to be completed. Using high-precision measuring equipment such as total stations and laser scanners, the surface of the ore body is scanned to generate three-dimensional point cloud data to obtain the volume of the ore body. According to the density or grade of the ore body, the measured volume can be converted into weight, thereby obtaining the mining volume.

[0041] According to one embodiment of the present invention, in step S105, a completion score is determined according to the mining volume and the remaining target mining volume.

[0042] According to an embodiment of the present invention, step S105 includes: setting the remaining target control cycle number; and determining the completion score according to the remaining target control cycle number, the mining volume and the remaining target mining volume.

[0043] According to one embodiment of the present invention, the remaining number of target control cycles to be performed is determined. The remaining number of target control cycles is the total number of target control cycles minus the number of historical control cycles and the number of a current control cycle. The target number of control cycles is the number of control cycles divided to achieve a given target mining volume. For example, if 100 control cycles are required to complete the target mining volume, i.e., the target number of control cycles, 50 historical control cycles have been implemented, and the remaining number of target control cycles is the target number of control cycles minus the number of historical control cycles and the number of a current control cycle, i.e., 100-50-1=49. The completion score can evaluate the progress of mining by comparing the actual mining volume with the degree of completion of the target mining volume.

[0044] According to one embodiment of the present invention, the completion score is determined according to the remaining target control cycle number, the mining volume and the remaining target mining volume, including: determining the completion score according to formula (3): ,

[0045] (3)

[0046] in, For the remaining target mining volume, is the mining amount of the current control cycle, is the number of remaining target control cycles, and if is the conditional function.

[0047] According to one embodiment of the present invention, in formula (3), It is the ratio of the remaining target mining volume to the mining volume of the current control cycle, indicating the number of control cycles required for the mining equipment to complete the remaining target mining volume according to the mining volume of the current control cycle. For example, if the mining volume of the current control cycle is 2 tons and the remaining target mining volume is 20 tons, then the number of control cycles required is 10. It means that when the ratio of the remaining target mining volume to the mining volume of the current control cycle is greater than or equal to the number of remaining target control cycles, the completion score is , when the ratio of the remaining target mining volume to the mining volume of the current control cycle is less than the number of remaining target control cycles, the completion score is 1. It is the relative difference between the ratio of the remaining target mining volume to the mining volume of the current control cycle and the number of remaining target control cycles, indicating the extent to which the number of control cycles required for the mining equipment to complete the remaining target mining volume according to the mining volume of the current control cycle exceeds the number of remaining target control cycles. The larger the relative difference, the greater the extent to which the number of control cycles required for the mining equipment to complete the remaining target mining volume according to the mining volume of the current control cycle exceeds the number of remaining target control cycles, and the lower the completion score. The smaller the relative difference, the smaller the extent to which the number of control cycles required for the mining equipment to complete the remaining target mining volume according to the mining volume of the current control cycle exceeds the number of remaining target control cycles, and the higher the completion score. The result of 1 minus the relative difference is the completion score.

[0048] In this way, the completion score can be determined based on the relationship between the number of control cycles required for the mining equipment to complete the remaining target mining volume according to the mining volume of the current control cycle and the remaining target control cycle number, and the progress of the mining project can be quantitatively evaluated to understand the production progress and completion status in real time. The power of the mining equipment can be adjusted to help quickly respond to changes in the production process and enable the smooth execution of the production plan.

[0049] According to one embodiment of the present invention, in step S106, the overload score, safety score and completion score respectively reflect the working status of the mining equipment, the operational safety and the progress of the mining project. The power of the mining equipment is adjusted based on the overload score, safety score and completion score to optimize the performance of the mining equipment.

[0050] According to an embodiment of the present invention, determining whether the power of the mining equipment in the next control cycle needs to be adjusted according to the overload score, the safety score and the completion score includes: obtaining a first condition C1, a second condition C2 and a second condition C3 according to formula (4);

[0051] (4)

[0052] in, Score the overload. is the overload score threshold, Score for safety, is the safety score threshold, Score the completion. is the completion score threshold; when any one of the first condition C1, the second condition C2 and the second condition C3 is met, it is determined that the power of the mining equipment in the next control cycle needs to be adjusted.

[0053] According to one embodiment of the present invention, in formula (4), the first condition C1 indicates that the overload score is greater than or equal to the overload score threshold, the mining equipment is in an overloaded working state, and the power of the mining equipment in the next control cycle needs to be adjusted. The second condition C2 indicates that the safety score is less than or equal to the temperature detection safety score threshold, the mining area environment is serious, affecting the operating safety of the mining equipment, and the power of the mining equipment in the next control cycle needs to be adjusted. The third condition C3 indicates that the completion score is less than or equal to the completion score threshold, the mining equipment cannot complete the remaining target mining volume within the remaining target cycle number according to the mining volume of the current control cycle, and the power of the mining equipment in the next control cycle needs to be adjusted.

[0054] According to an embodiment of the present invention, when at least one of the first condition C1, the second condition C2 and the third condition C3 is satisfied, it is determined that the power of the mining equipment in the next control cycle needs to be adjusted.

[0055] In this way, the overload score, safety score and completion score can be used to determine whether the power of the mining equipment in the next control cycle needs to be adjusted, and the adjustment of the mining equipment power can be decided based on the scoring results, thereby improving the accuracy of the judgment on adjusting the power of the mining equipment in the next control cycle, so that the mining operation can flexibly respond to different operating conditions and external conditions, thereby improving operational efficiency and resource utilization.

[0056] According to one embodiment of the present invention, in step S107, if the power of the mining equipment in the next control cycle needs to be adjusted, the power of the adjusted mining equipment is determined based on the power of the mining equipment in the current control cycle, the current data, the environmental data, the mining volume and the remaining target mining volume.

[0057] According to one embodiment of the present invention, if the power of the mining equipment in the next control cycle needs to be adjusted, the power of the mining equipment after adjustment is determined according to the power of the mining equipment in the current control cycle, the current data, the environmental data, the mining amount and the remaining target mining amount, including: determining the power of the mining equipment after adjustment according to formula (5) ,

[0058] (5)

[0059] in, is the power of the mining equipment in the current control cycle, For the remaining target mining volume, is the mining amount of the current control cycle, is the remaining target control cycle number, is the current data of the ith power-consuming device at the kth moment of the current control cycle, is the current data threshold of the i-th power consuming device, is the temperature data at the kth moment of the current control cycle, is the preset temperature, is the humidity data at the kth moment of the current control cycle, To preset humidity, is the harmful gas concentration data of the jth harmful gas at the kth moment in the current control cycle, is the harmful gas concentration threshold of the jth harmful gas, is the number of power consuming devices, is the amount of harmful gases, is the number of moments in the control cycle, i≤ , j≤ , k≤ , and i, j, k, , and All are positive integers.

[0060] According to one embodiment of the present invention, in formula (5), It is the ratio of the number of control cycles required for the mining equipment to complete the remaining target mining amount according to the mining amount of the current control cycle to the remaining target control cycles. The closer the ratio is to 1, the smaller the impact of the number of control cycles required for the mining equipment to complete the remaining target mining amount according to the mining amount of the current control cycle on the power of the mining equipment. It is the ratio of the current data of the ith power consuming device at the kth moment of the current control cycle to the current data threshold of the ith power consuming device. The closer the ratio is to 1, the smaller the impact of the current data change on the power of the mining equipment. It is the ratio of the temperature data at the kth moment of the current control cycle to the preset temperature. The closer the ratio is to 1, the smaller the impact of the temperature data change on the power of the mining equipment. It is the ratio of the humidity data at the kth moment of the current control cycle to the preset humidity. The closer the ratio is to 1, the smaller the impact of humidity data changes on the power of the mining equipment. It is the ratio of the harmful gas concentration data of the jth harmful gas at the kth moment in the current control cycle to the harmful gas concentration threshold of the jth harmful gas. The closer the ratio is to 1, the smaller the impact of the change in harmful gas concentration data on the power of the mining equipment. It indicates that the number of control cycles required for the mining equipment to complete the remaining target mining volume according to the mining volume of the current control cycle is positively correlated with the power of the mining equipment, and the current data, temperature data, humidity data and harmful gas concentration data are negatively correlated with the power of the mining equipment. For example, when the number of control cycles required for the mining equipment to complete the remaining target mining volume according to the mining volume of the current control cycle is larger, the mining volume needs to be increased, that is, the running speed of the mining equipment is accelerated, and the power required by the mining equipment is larger, so that the production task can be completed on time. When the current data is larger, the load of the power-consuming equipment increases, and the power of the mining equipment needs to be reduced, so as to reduce the problem of damage to the mining equipment due to long-term overload operation. When the temperature data, humidity data and harmful gas concentration data are larger, the mining environment is worse, and the electrical performance of the mining equipment is more easily affected. The power of the mining equipment needs to be reduced to protect the mining equipment and extend its service life. Therefore, the items related to the number of control cycles required for the mining equipment to complete the remaining target mining volume according to the mining volume of the current control cycle are placed in the numerator, indicating that the number of control cycles required for the mining equipment to complete the remaining target mining volume according to the mining volume of the current control cycle is larger relative to the number of remaining target control cycles, that is, The larger the value, the greater the power of the mining equipment. The items related to current data, temperature data, humidity data and harmful gas concentration data are placed in the denominator, that is, , , and The smaller the value, the more powerful the mining equipment. The power of the mining equipment in the current control period of multiple power-consuming devices and multiple harmful gases at multiple moments in the current control period is weighted averaged to obtain the adjusted power of the mining equipment.

[0061] In this way, the power of the adjusted mining equipment can be determined through the power, current data, environmental data, mining volume and remaining target mining volume of the mining equipment in the current control cycle. The influence of the current data, environmental data, mining volume and remaining target mining volume on the power of the mining equipment can be comprehensively considered, so as to determine the power of the adjusted mining equipment based on the influence and the power of the mining equipment in the current control cycle, so that the power of the adjusted mining equipment can adapt to different working conditions, working environments and production needs, thereby improving the comprehensiveness and accuracy of the power of the adjusted mining equipment.

[0062] According to one embodiment of the present invention, in step S108, at the start of the next control cycle, the mining equipment is operated according to the adjusted power of the mining equipment. At the start of each control cycle, the power of the mining equipment is dynamically adjusted according to real-time data, thereby improving the efficiency and performance of the mining equipment.

[0063] According to the mining equipment power intelligent control method of the embodiment of the present invention, by real-time monitoring of current data, it is possible to quickly identify whether the mining equipment is overloaded, and reduce mechanical wear and failure caused by overload. By evaluating the safety score through environmental data, it is possible to timely discover operational hazards, slow down the mining speed, reduce the accident rate, and ensure the safety of mining equipment. By monitoring the mining volume and the remaining target mining volume, the production progress and completion status can be understood in real time. The power of the mining equipment is adjusted based on the changes in the above various factors, which improves the automation and intelligence level of the mining equipment, reduces the need for manual intervention, and thus improves the efficiency of the mining equipment. When determining the overload score, the overload score can be determined based on the comparison result of the current data and the current data threshold, and the load state of the mining equipment can be quantitatively evaluated, which improves the accuracy and objectivity of the overload score, thereby optimizing the operation of the mining equipment, reducing the downtime and maintenance costs caused by equipment failure, and improving the use efficiency of the mining equipment. When determining the safety score, the safety score can be determined based on the severity of the environment in the mining area, and the mining area environment can be evaluated from three aspects: temperature, humidity and harmful gas concentration. The comprehensiveness, objectivity and accuracy of the safety score are improved, and potential safety hazards can be discovered in time, and the power of mining equipment can be adjusted accordingly, so as to effectively prevent accidents and ensure the safety of mining equipment. When determining the completion score, the completion score can be determined based on the relationship between the number of control cycles required for the mining equipment to complete the remaining target mining volume according to the mining volume of the current control cycle and the number of remaining target control cycles. The progress of the mining project can be quantitatively evaluated and the production progress and completion status can be understood in real time. Adjusting the power of mining equipment can help to quickly respond to changes in the production process and enable the production plan to be smoothly executed. When determining whether the power of the mining equipment in the next control cycle needs to be adjusted, the overload score, safety score and completion score can be used to determine whether the power of the mining equipment in the next control cycle needs to be adjusted. The adjustment of the mining equipment power is determined according to the score results, which improves the judgment accuracy of adjusting the power of the mining equipment in the next control cycle, so that the mining operation can flexibly respond to different operating conditions and external conditions, thereby improving operational efficiency and resource utilization. When determining the power of the adjusted mining equipment, the power of the adjusted mining equipment can be determined through the power, current data, environmental data, mining volume and remaining target mining volume of the mining equipment in the current control cycle. The influence of the current data, environmental data, mining volume and remaining target mining volume on the power of the mining equipment can be comprehensively considered, so as to determine the power of the adjusted mining equipment based on the influence and the power of the mining equipment in the current control cycle, so that the power of the adjusted mining equipment can adapt to different working conditions, working environments and production needs, thereby improving the comprehensiveness and accuracy of the power of the adjusted mining equipment.
