[0050] Referring to Figures 1 and 2, the first embodiment of the present invention provides a method for optimizing the operation of intelligent mining trucks based on environmental characteristics, including:
[0051] S1: Collect mining truck operating status data based on sensors installed around the mining truck, transmit the data to a central database via the Internet, and design intelligent data processing algorithms in the database to dynamically adjust the collected data.
[0052] Among them, the mining truck operation status data includes the acceleration, angle and position information of the mining truck obtained by the sensor and the surrounding environment image drawn. The acceleration, angle and position information of the mining truck are calculated based on wind speed, temperature, humidity and air pressure.
[0053] The formula for calculating the acceleration of a mine car is:
[0054] Among them, a i Represents time t i acceleration, v w The wind speed is represented by m, the mass of the mine car is represented by w. ijk The weight parameters are represented by i, j, and k, which represent the order of the polynomial.
[0055] The formula for calculating the angle of the mine car is:
[0056] Where, θ i+1 Represents time t i+1 The angles are k1, k2, k3, and k4, which represent coefficients, and I represents the moment of inertia of the mine car.
[0057] The formula for calculating the location information of the mining truck is:
[0058] Where, x i+1 Represents time t i+1 Position, v i and v i+1 v represents the velocity at adjacent moments. mid The value represents the median of adjacent velocities, Δt represents the sampling time interval, and v w The wind speed is represented by m, and the mass of the mine car is represented by m.
[0059] S1.1: The design of intelligent data processing algorithms includes the calculation results of the mine car running status data dynamically adjusted by a deep learning-based neural network model, the establishment of a multilayer perceptron intelligent data algorithm model, and the input of the mine car acceleration, mine car angle and mine car position information as the input of the intelligent data algorithm model. At this time, the output result is the dynamically adjusted result.
[0060] The specific calculation formula for the intelligent data algorithm model is: h(1) =g (1) (W (1) ·X+b (1) h (2) =g (2) (W (2) ·h (1) +b (2) ... h (n) =g (n) (W (2) ·h (n-1) +b (n) Y = W (n+1) ·h (n) +b (n+1)
[0061] Where X represents the calculated results of the input acceleration, angle, and position, and h (i) W represents the output of the i-th hidden layer. (i) and b (i) The weights and biases of the i-th layer, g (i) Y represents the activation function of the i-th layer, and Y represents the output of the model, i.e., the adjusted result.
[0062] Furthermore, the design of intelligent data processing algorithms includes dynamically adjusting the calculation results of mining truck operating status data based on a deep learning-based neural network model, and establishing an intelligent data algorithm model of a multilayer perceptron. When the input acceleration, angle, and position calculation results are a... i =2.5, θ i =30°, x i =100.
[0063] S2: Analyze the operating status of the mining truck based on the results of dynamic adjustment data, establish a machine learning prediction model based on the analysis results, sample the operating status data of the mining truck based on the prediction model, and optimize the operation of the mining truck based on the sampling results.
[0064] The prediction model includes labeling the adjusted results as target variables. Labeling includes standardizing the target variables based on time series data and calculating the target variables using a nearest neighbor interpolation algorithm. The interpolation algorithm includes polynomial interpolation and linear interpolation.
[0065] If the target variable feature X = {x i x2, ..., x n When dealing with missing values x in the target variable, i When a marker is detected around the target variable, a linear interpolation algorithm is used to sample the target variable.
[0066] When no markers are detected around the target variable, a polynomial interpolation algorithm is used to sample the target variable, and the missing values are estimated based on the sampling results.
[0067] The specific formula for the linear interpolation algorithm is as follows:
[0068] in, Indicates missing value x i The estimated value, x nearest x represents i The known value before, x next x represents i The known value after that, d represents x i With x nearest The distance between them, Δ represents x next and x nearest The distance between them;

[0071] Furthermore, the distances mentioned above include two: the distance between the missing value and the previous known value, and the distance between the missing value and the next known value. Assuming the distance between the missing value and the previous known value is d1 = 10, and the distance between the missing value and the next known value is d2 = 15, this means the missing value is 10 units of time away from the previous known value and 15 units of time away from the next known value. The distances between the missing and next values are shown in Table 1 below.
[0072] Table 1: Distance data between preceding and following values
[0073] The table above shows the distance between each missing value and the previous and next known values during interpolation calculations. This distance information is crucial for determining which interpolation algorithm to use and how to estimate the missing values.
[0074] S2.1: Sampling includes outlier detection of the calculation results of the target variable using quantile methods;
[0075] Calculate the median, first quartile, and third quartile of feature X. Identify outliers based on the interquartile range. Set thresholds for outliers as σ and τ. Replace outliers exceeding the threshold range with the median. The specific calculation formula for outlier detection is as follows:
[0076] Where, x i Q represents the observed value of feature X. 0.5 represents the median, Q 0.25 Q represents the first quartile. 0.75 The third quartile is represented by IQR, which represents the interquartile range.
[0077] S2.2: The replacement involves comparing the observations with the interquartile range to determine the sampling stage. The specific steps are as follows:
[0078] If x i Greater than Q 0.75 When +1.5×IQR, then x i It is at the upper limit outlier, and x is also... i Replace with median Q 0.5 At this point, we are in the first type of sampling phase;
[0079] If x i Less than Q 0.25 When x = -1.5 × IQR, then i It is at the lower limit outlier, and x is also... i Replace with median Q 0.5 This is currently in the second sampling phase.
[0080] Furthermore, the upper limit mentioned above is 1.5 times the interquartile range plus the third quartile, i.e., Q. 0.75 +1.5×IQR, the upper limit is obtained by using the third quartile Q 0.75 The result is obtained by adding 1.5 times the interquartile range (IQR).
[0081] S2.3: The first sampling stage includes analyzing the sampling data of the mine car's running speed to determine the predetermined path where the mine car has deviated;
[0082] The second sampling phase includes identifying fault warning signals of mining trucks based on a predetermined path and monitoring the operation of mining trucks in real time.
[0083] In a preferred embodiment, an intelligent mining truck operation optimization system based on environmental characteristics includes an adjustment module that transmits data to a central database via the Internet, and designs an intelligent data processing algorithm in the database to dynamically adjust the collected data.
[0084] The optimization module samples the mining truck's operating status data based on the prediction model and uses the sampling results to optimize the mining truck's operation.
[0085] The above-mentioned unit modules can be embedded in the processor of the computer device in hardware form or independent of it, or they can be stored in the memory of the computer device in software form, so that the processor can call and execute the corresponding operations of the above modules.
[0086] The computer device can be a terminal, comprising a processor, memory, communication interface, display screen, and input devices connected via a system bus. The processor provides computing and control capabilities. The memory includes non-volatile storage media and internal memory. The non-volatile storage media stores the operating system and computer programs. The internal memory provides an environment for the operation of the operating system and computer programs stored in the non-volatile storage media. The communication interface is used for wired or wireless communication with external terminals; wireless communication can be achieved through Wi-Fi, carrier networks, NFC (Near Field Communication), or other technologies. The display screen can be an LCD screen or an e-ink screen. The input devices can be a touch layer covering the display screen, buttons, a trackball, or a touchpad on the computer device's casing, or an external keyboard, touchpad, or mouse.
[0087] In summary, this invention utilizes intelligent mining truck operation optimization technology, employs sensors to collect data and dynamically adjusts it using intelligent algorithms, thereby achieving real-time monitoring and optimization of the mining truck's operating status. Through data analysis and machine learning prediction, it improves the efficiency and safety of mining truck operation, reduces accident risks, and ultimately enhances mine production efficiency and economic benefits.

The sampling time interval was set to 0.1 seconds, the wind speed to 3 m / s, and the weight of the mining truck to 1000 kg. The data was analyzed, and a deep learning-based neural network model was established to predict the status of the mining trucks. In the modeling process, two hidden layers were set, with 50 and 30 nodes in each layer, respectively.
[0091] After model training, dynamically adjusted data is input into the model for prediction. Data sampling is performed based on the prediction results, and the data is processed using a nearest neighbor interpolation algorithm. The sampling stage is determined based on outliers. The operation of the mining truck is optimized based on the sampling results, including analyzing speed data and identifying potential fault warning signals to monitor the operating status of the mining truck in real time. The entire experiment aims to improve the safety and efficiency of mining truck operation by comprehensively utilizing data processing and analysis techniques.
