[0002] Mining production involves many stages, such as mining operations, transportation, crushing and grinding, etc. These stages require the use of various equipment to complete them. Therefore, mining production is a typical high-energy-consuming industry. In order to reduce energy costs, it is particularly important to monitor, predict and optimize energy consumption in mining production. However, existing energy consumption monitoring, prediction, and optimization technologies typically rely solely on historical energy consumption data to predict future energy consumption trends, neglecting various operating parameters of equipment and the impact of equipment aging on energy consumption. Furthermore, they are unable to quickly identify the operating parameters that need to be adjusted first, resulting in inaccurate energy consumption monitoring and prediction and insufficient optimization efficiency. Summary of the Invention

Then, based on the energy consumption impact index analysis, a first future energy consumption value is obtained. Based on the future aging index of the corresponding operating equipment, a second future energy consumption value is obtained through corresponding preset second neural network models. The average of the first future energy consumption value and the second future energy consumption value is used to calculate the comprehensive future energy consumption value of the corresponding operating equipment; if the comprehensive future energy consumption value of the corresponding operating equipment is greater than its preset energy consumption threshold at the same time in the future, it is marked as an abnormal equipment. The energy consumption impact index of various operating data of each abnormal device is obtained, and the adjustment priority of various operating data of the corresponding abnormal device is obtained according to the order of the energy consumption impact index.
[0004] Furthermore, the step of analyzing the current aging index of the corresponding operating equipment through historical data specifically includes: Analyze the deviation (PL) and volatility (BD) of various historical operating data of the corresponding operating equipment; The failure impact index GS of the corresponding operating equipment is analyzed by historical maintenance data, and the performance degradation index XS is analyzed based on PL and BD. Analyze the current aging index LS of the corresponding operating equipment: LS = gsk × GS + xsk × XS; Among them, gsk and xsk are the preset fault weight and preset performance weight, respectively.

For the volatility of the i-th type of historical operating data corresponding to the operating equipment, For the preset data influence weight of the i-th type of historical operating data of the corresponding operating equipment, plk and bdk respectively preset deviation influence weight and preset fluctuation influence weight.
[0009] Furthermore, the prediction of the future aging index of the corresponding operating equipment based on current operating data specifically includes: Based on the analysis method of the current aging index, the historical aging degree of the corresponding operating equipment at multiple historical moments and the corresponding second historical operating data are obtained; The historical operation data and the corresponding historical aging index of a historical moment, the historical aging degree of the next adjacent historical moment, and the duration between the next adjacent historical moment are taken as a set of sample data, and then multiple sets of sample data are obtained. After the pre-built deep learning model is pre-trained using the multiple sets of sample data, the current operating data, current aging level, and required future duration of the corresponding operating device are used as inputs to output a predicted value of the future aging index.
[0010] Furthermore, the process of matching energy consumption impact indices to various operating data of corresponding operating equipment based on historical data specifically involves: The standard deviation of the historical energy consumption values of the corresponding operating equipment is calculated as its energy consumption volatility. Calculate the ratio of volatility to energy consumption volatility of various historical operating data for the corresponding operating equipment, and use it as the energy consumption driving index for the corresponding type of operating data; Based on the magnitude of the energy consumption drive index, sort the various operating data of the corresponding operating equipment from smallest to largest, starting with the serial number 1; Calculate the energy consumption impact index of various operating data for the corresponding operating equipment: ; ; This refers to the energy consumption impact index of the i-th type of operating data for the corresponding operating equipment. The weight of the level influence of the i-th type of operating data for the corresponding operating equipment. The pre-set weights for the i-th type of running data are manually assigned. Let i be the sequence number of the i-th type of running data.

The anomaly screening module is used to calculate the comprehensive future energy consumption value of the corresponding operating equipment by averaging the first future energy consumption value and the second future energy consumption value. If the comprehensive future energy consumption value of the corresponding operating equipment is greater than its preset energy consumption threshold at the same time in the future, it is marked as an abnormal device. The priority strategy module is used to obtain the energy consumption impact index of various operating data of each abnormal device, and to obtain the adjustment priority of various operating data of the corresponding abnormal device according to the order of the energy consumption impact index.

It also quantifies the degree and stability of equipment operating parameters deviating from preset expected values by analyzing deviation and volatility, effectively reflecting the performance degradation trend. It also analyzes the impact index of each fault type by combining different fault types, their frequency of occurrence, severity, and the severity of the last occurrence. In particular, it introduces the severity of the last occurrence to reflect the recent dynamics of the equipment in the corresponding fault type, and more comprehensively reflects the actual impact of the fault type on energy consumption. Meanwhile, the energy consumption driving index is quantified by the ratio of energy consumption volatility to operational data volatility, accurately identifying the operational parameters that have the greatest impact on energy consumption volatility. The energy consumption driving index is used to sort various operational data to reflect their impact on energy consumption. The final energy consumption impact index is obtained by combining the impact level with manually preset weights, thereby improving the effectiveness of the energy consumption impact index of each operational data and thus enhancing the accuracy of energy consumption optimization at the operational data level.

[0020] Example 1 See Figure 1 As shown, the present invention provides a method for monitoring and optimizing mine energy consumption based on big data, which specifically includes the following steps: S1. Obtain the current operating data and historical data of each operating device. The historical data includes historical operating data, historical maintenance data, and historical energy consumption values.
[0021] S2. Analyze the current aging index of the corresponding operating equipment through historical data, and then predict the future aging index of the corresponding operating equipment by combining the current operating data.
[0022] S3. Match energy consumption impact indices to various operating data of corresponding operating equipment based on historical data; S4. Based on various current operating data, multiple predicted energy consumption values are obtained through the corresponding preset first neural network model. Then, the first future energy consumption value is obtained by analyzing the energy consumption impact index. Based on the future aging index of the corresponding operating equipment, the second future energy consumption value is predicted through the corresponding preset second neural network model. S5. Calculate the comprehensive future energy consumption value of the corresponding operating equipment by averaging the first future energy consumption value and the second future energy consumption value; if the comprehensive future energy consumption value of the corresponding operating equipment is greater than its preset energy consumption threshold at the same time in the future, it is marked as an abnormal equipment. S6. Obtain the energy consumption impact index of various operating data of each abnormal device, and obtain the adjustment priority of various operating data of the corresponding abnormal device according to the order of the size of the energy consumption impact index.
[0023] In step S1, the current operating data of the running equipment is the operating data used by the equipment in the current work phase. The operating data of the equipment is set according to the preset production plan. Different types of running equipment have their own types of operating data, such as pressure, speed, etc. The corresponding type of operating data of each equipment is obtained according to actual needs.
[0024] The historical maintenance data is extracted from the equipment's maintenance records or maintenance logs, including but not limited to maintenance time, fault type, and specific maintenance content.
[0025] In step S1, all acquired data undergoes data preprocessing, including but not limited to missing value handling and outlier detection. Missing value handling identifies missing values in the data and can be completed using linear interpolation or mean imputation. Data segments with long-term, continuous missing values are marked as unusable and removed. Outlier detection uses existing statistical methods or box plots to identify outliers in the data, and then smooths or removes them.
[0026] In step S2, the step of analyzing the current aging index of the corresponding operating equipment through historical data specifically includes: Sa21, Analyze the deviation PL and volatility BD of various historical operating data of the corresponding operating equipment; Sa22, analyze the fault impact index GS of the corresponding operating equipment through historical maintenance data, and analyze the performance degradation index XS based on PL and BD; Sa23, Analyze the current aging index LS of the corresponding operating equipment: LS = gsk × GS + xsk × XS; Among them, gsk and xsk are the preset fault weight and preset performance weight, respectively.
[0027] The higher the current aging index, the more severe the current aging of the corresponding operating equipment.
[0028] The degree of deviation of equipment operating parameters from the preset expected value (deviation PL) and stability (volatility BD) are quantified to effectively reflect the performance degradation trend; by distinguishing the impact weight of failure and performance degradation, the rationality of aging assessment is improved.
[0029] In step Sa21, the analysis method for the deviation PL is specifically as follows: ; in, The deviation of the i-th type of historical operating data for the corresponding operating equipment. To obtain the amount of historical running data of the i-th type, Let be the value of the i-th type of historical running data at time t. Let be the preset expected value corresponding to the i-th type of historical running data at time t.
[0030] In step Sa21, the analysis method for the volatility BD is specifically as follows: S211. Obtain the corresponding preset expected data segment based on the preset expected value corresponding to the historical operation data; S212. Divide the corresponding historical running data into multiple sub-segments by taking the same and consecutive preset expected values as a sub-segment in a preset expected data segment; S213. Calculate the standard deviation of each segment in the historical running data; S214. Calculate the mean of the standard deviations of various historical operating data to obtain the volatility of the corresponding historical operating data.
[0031] By dividing the data into segments, calculating the standard deviation of each segment, and then performing a mean calculation, the volatility of the corresponding historical operating data is represented. This avoids the impact of changes in actual parameter settings, thereby improving the effectiveness and accuracy of the volatility of the corresponding historical operating data.
[0032] To clearly illustrate the above volatility analysis method, the following examples will explain each step: Based on the preset expected value corresponding to the historical operating data, obtain the corresponding preset expected data segment. For example, if the historical operating data a of device A is obtained and arranged in chronological order as 2, 2, 3, 4, 6, 6, 1, 3, 2, the preset expected data segment corresponding to this historical operating data is the same chronological arrangement of the preset expected value corresponding to the time of each data point of the historical operating data. Assume that the preset expected data segment corresponding to historical operating data a is 2, 2, 2, 5, 5, 5, 2, 2, 2. The corresponding historical running data is divided into multiple sub-segments by taking the same and consecutive preset expected values as a sub-segment within a preset expected data segment. For example, the preset expected data segment mentioned above is divided into three sub-segments: [2, 2, 2], [5, 5, 5], and [2, 2, 2]. The corresponding historical running data a is divided into three sub-segments: [2, 2, 3], [4, 6, 6], and [1, 3, 2]. It should be noted that the values in the above examples are for illustrative purposes only and do not represent the actual data values.
[0033] In step Sa22, the analysis method of the fault impact index GS is as follows: S221. Analyze the impact index YS of each historical fault type of the corresponding operating equipment: ; ; in, This represents the impact index of the i-th historical fault type that occurred in the corresponding operating equipment. This represents the number of occurrences of the i-th historical fault type for the corresponding operating equipment. This represents the overall severity level of the i-th historical fault type corresponding to the operating equipment. To represent the severity level of the i-th historical fault type of the corresponding operating equipment at its last occurrence, pk, ck, and lk are the preset influence weights for the number of occurrences, the preset influence weight for the overall severity, and the preset influence weight for the final severity, respectively. This represents the severity level of the nth occurrence of the i-th historical fault type corresponding to the operating equipment. S222. Analyze the fault impact index GS of the corresponding operating equipment: ; Wherein, GN represents the number of historical fault types that have occurred in the corresponding operating equipment. The preset type influence weight for the i-th historical fault type that occurs in the corresponding operating equipment.
[0034] It should be noted that the severity level of the fault is determined by the maintenance personnel through an assessment of the fault according to a preset evaluation standard and recorded in the maintenance record or repair log.
[0035] The impact index of each fault type is analyzed by combining different fault types, their frequency of occurrence, severity, and the severity of the last occurrence. In particular, the severity of the last occurrence is introduced to reflect the recent dynamics of the equipment under the corresponding fault type, so as to more comprehensively reflect the actual impact of the fault type on energy consumption.
[0036] In step Sa22, the analysis method for the performance degradation index XS is as follows: ; Where YN1 represents the number of types of historical operating data for the corresponding operating device. For the volatility of the i-th type of historical operating data corresponding to the operating equipment, For the preset data influence weight of the i-th type of historical operating data of the corresponding operating equipment, plk and bdk respectively preset deviation influence weight and preset fluctuation influence weight.
[0037] In step S2, the prediction of the future aging index of the corresponding operating equipment based on the current operating data specifically includes: Sb21. Based on the analysis method of the current aging index, obtain the historical aging degree of the corresponding operating equipment at multiple historical moments and the corresponding second historical operating data; Sb22. Take the historical operation data and the corresponding historical aging index of a historical moment, the historical aging degree of the next adjacent historical moment, and the duration between the next adjacent historical moment as a set of sample data, and then obtain multiple sets of sample data. Sb23. After the pre-built deep learning model is pre-trained using the multiple sets of sample data, the current operating data, current aging level, and required future duration of the corresponding operating device are used as inputs to output the predicted value of the future aging index.
[0038] In step S3, matching energy consumption impact indices to various operating data of the corresponding operating equipment based on historical data specifically involves: S31. Calculate the standard deviation of the historical energy consumption values of the corresponding operating equipment as its energy consumption volatility. S32. Calculate the ratio of the volatility of various historical operating data to the energy consumption volatility of the corresponding operating equipment, and use it as the energy consumption driving index of the corresponding type of operating data. S33. Sort the various operating data of the corresponding operating equipment in ascending order, starting from the number 1, according to the size of the energy consumption drive index; S34. Calculate the energy consumption impact index of various operating data for the corresponding operating equipment: ; ; This refers to the energy consumption impact index of the i-th type of operating data for the corresponding operating equipment. The weight of the level influence of the i-th type of operating data for the corresponding operating equipment. The pre-set weights for the i-th type of running data are manually assigned. Let i be the sequence number of the i-th type of running data. The sum of the sequence numbers of each operating data of the corresponding operating device is represented by k1 and k2, which are the first preset weight and the second preset weight, respectively.
[0039] The energy consumption driving index is quantified by the ratio of energy consumption volatility to operational data volatility. This accurately identifies the operational parameters that have the greatest impact on energy consumption volatility. The energy consumption driving index is used to rank various operational data to reflect their influence on energy consumption. The final energy consumption impact index is obtained by combining the influence level with manually preset weights. This improves the effectiveness of the energy consumption impact index for each operational data point, thereby enhancing the accuracy of energy consumption optimization at the operational data adjustment level.
[0040] In step S4, the process of predicting multiple predicted energy consumption values based on various current operating data using corresponding preset first neural network models, and then obtaining a first future energy consumption value based on energy consumption impact index analysis, specifically involves: ; This represents the first future energy consumption value of the corresponding operating equipment at time t. This represents the number of current operating data types for the corresponding running device. This represents the predicted energy consumption value corresponding to the i-th type of current operating data of the corresponding operating device at time t in the future.
[0041] The first neural network model is pre-trained by using multiple sets of historical operating data of corresponding types, corresponding historical energy consumption values, and corresponding time series as training samples.
[0042] In step S4, the second future energy consumption value is predicted by the corresponding preset second neural network model based on the future aging index of the corresponding operating equipment. The second neural network model is pre-trained by using multiple sets of historical aging indices of the corresponding operating equipment, the corresponding historical energy consumption values, and the corresponding time series as training samples.
[0043] In step S5, if the overall future energy consumption value of a corresponding operating device is greater than its preset energy consumption threshold at the same future time, it is marked as an abnormal device. That is, if the overall future energy consumption value of a certain operating device at a future time t is greater than the preset energy consumption threshold of that device at a future time t, then that device is marked as an abnormal device. The preset energy consumption threshold is set based on the timely completion of the production plan.
[0044] In step S6, the energy consumption impact index of various operating data of each abnormal device is obtained. According to the order of the energy consumption impact index, the adjustment priority of various operating data of the corresponding abnormal device is obtained. According to the production plan, the operator can quickly find the abnormal device while ensuring the timely completion of the production plan. The operator can also realize the adjustment priority of the abnormal device according to the magnitude of the comprehensive future energy consumption value. At the same time, according to the adjustment priority of the operating data, the various operating data of the device are adjusted in sequence to efficiently reduce energy consumption.

The historical data includes historical operating data, historical maintenance data, and historical energy consumption values. The aging analysis module is used to analyze the current aging index of the corresponding operating equipment through historical data, and then combine the current operating data to predict the future aging index of the corresponding operating equipment. The index matching module is used to match energy consumption impact indices to various operating data of corresponding operating equipment based on historical data; The first prediction module is used to predict multiple predicted energy consumption values based on various types of current operating data through corresponding preset first neural network models, and then to obtain the first future energy consumption value based on energy consumption impact index analysis. The second prediction module is used to predict the second future energy consumption value based on the future aging index of the corresponding operating equipment through a corresponding preset second neural network model. The anomaly screening module is used to calculate the comprehensive future energy consumption value of the corresponding operating equipment by averaging the first future energy consumption value and the second future energy consumption value. If the comprehensive future energy consumption value of the corresponding operating equipment is greater than its preset energy consumption threshold at the same time in the future, it is marked as an abnormal device. The priority strategy module is used to obtain the energy consumption impact index of various operating data of each abnormal device, and to obtain the adjustment priority of various operating data of the corresponding abnormal device according to the order of the energy consumption impact index.
