Description

Technical Field

[0001] This invention relates to the field of intelligent coal feeding technology, and in particular to an intelligent coal feeding method and system for bucket wheel excavators. Background Technology

[0002] Currently, with the increasing population and rapid technological development, the demand for coal resources remains substantial, and the stockpiling and transportation of coal resources remains a key concern for coal development companies.

[0003] However, the existing equipment systems for mining, stockpiling, and transporting coal are not yet perfect, resulting in issues such as excavation collapse and inaccurate excavation, which leads to waste of bucket wheel excavator equipment.

[0004] Therefore, the present invention provides an intelligent coal feeding method and system for bucket wheel excavators. Summary of the Invention

[0005] This invention provides an intelligent coal loading method and system for bucket wheel excavators, which determines the working attribute parameters of the bucket wheel excavator by means of the stacking parameters of the target coal pile, and adjusts them based on key coal parameters, so that the obtained working attribute parameters are more accurate. Furthermore, the original working instructions are optimized based on operability, so that the issued working instructions are more precise.

[0006] This invention provides an intelligent coal feeding method for bucket wheel excavators, comprising:

[0007] Step 1: Obtain key parameters of the current target coal pile and key parameters of the coal in real time;

[0008] Step 2: Based on the stacking key parameters, upload them to the intelligent management terminal of the bucket wheel excavator to determine the first working attribute parameters of the bucket wheel excavator;

[0009] Step 3: Adjust the first working attribute parameters of the bucket wheel excavator based on the key coal parameters to obtain the second working attribute parameters, and issue the original working command based on the second working attribute parameters;

[0010] Step 4: Determine the operability of the original work instruction. If it is operable, control the bucket wheel excavator to intelligently feed coal based on the original work instruction. Otherwise, optimize the original work instruction based on the intelligent management terminal.

[0011] In one possible implementation, key parameters of the current target coal pile's stacking and key parameters of the coal are acquired in real time, including:

[0012] Step 11: Measure the stacking parameters of the target coal pile from all angles using preset instruments and transmit the data to the parameter management terminal in real time;

[0013] Step 12: Based on the historical data of the parameter management terminal, select the available parameters from the stacking parameters as the key stacking parameters for the target coal pile;

[0014] Step 13: Collect and test coal samples from several areas of the target coal pile using the preset coal quality testing tools, obtain the key parameters of the coal in the target coal pile, and upload them to the parameter management terminal.

[0015] In one possible implementation, the first operating attribute parameters of the bucket wheel excavator are determined by uploading the key stacking parameters to the intelligent management terminal of the bucket wheel excavator, including:

[0016] Step 20: Based on the obtained key parameters of the target coal pile and key parameters of the coal, perform data preprocessing to obtain the first key parameters of the pile and the first key parameters of the coal.

[0017] Step 21: Determine the key parameters of the first stacking;

[0018] If there are no error parameters in the first stacking key parameters, then retain the current first stacking key parameters;

[0019] Conversely, if the current key parameters for the first pile are not found, the pile parameters for the target coal pile are collected again.

[0020] Step 22: The intelligent management terminal based on the bucket wheel excavator identifies and detects the first key stacking parameters that are retained, thereby determining the first working attribute parameters of the bucket wheel excavator.

[0021] In one possible implementation, the intelligent management terminal based on the bucket wheel excavator identifies and detects the retained first key stacking parameters, thereby determining the first operating attribute parameters of the bucket wheel excavator, including:

[0022] Step 221: The intelligent management terminal based on the bucket wheel excavator identifies the first stacking key parameters that have been retained, and fills each parameter of the first stacking key parameters into the corresponding position of the key parameter table based on the identification results;

[0023] Step 222: Calculate the filling results of the filled part of the key parameter table to obtain the first original working attribute parameters of the bucket wheel excavator corresponding to the first stacking key parameters;

[0024] The unfilled parts in the key parameter table are filled in based on the corresponding standard parameters, and then combined with the first original working attribute parameters to obtain the first working attribute parameters of the bucket wheel excavator.

[0025] In one possible implementation, the first operating attribute parameters of the bucket wheel excavator are adjusted based on the key coal parameters to obtain second operating attribute parameters, and the original operating instructions are issued based on the second operating attribute parameters, including:

[0026] Step 31: Determine the coal quality of the target coal pile based on the first key coal parameters, and compare it with the preset quality table to obtain the quality grade of the target coal pile;

[0027] Step 32: Compare the standard working attribute parameters corresponding to the quality level with the first working attribute parameters, calculate the executability of the first working attribute parameters, and obtain the second working attribute parameters;

[0028] If the executability of the first working attribute parameter is less than the preset executability, then the first working attribute parameter is adjusted based on the standard working attribute parameter to obtain the second working attribute parameter.

[0029] Conversely, the first working attribute parameter is used as the second working attribute parameter;

[0030] Step 33: Use the second working attribute parameter as the original working parameter of the bucket wheel excavator and issue the original working command.

[0031] In one possible implementation, the operability of the original work instruction is determined. If operable, the bucket wheel excavator is controlled to intelligently feed coal based on the original work instruction; otherwise, the original work instruction is optimized based on the intelligent management terminal, including:

[0032] Step 41: Based on the original work instructions, combined with real-time environmental factors, bucket wheel excavator equipment wear factors, and external factors, determine the operability of the instructions on the intelligent management terminal of the bucket wheel excavator;

[0033] If the operability of the instruction is greater than 1, then the original work instruction is determined to be operable, and the bucket wheel excavator is controlled to perform intelligent coal feeding based on the original work instruction.

[0034] Conversely, the second working attribute parameter is adjusted based on the external factors to obtain the third working attribute parameter, and the first working instruction is obtained based on the third working attribute parameter.

[0035] Step 42: Determine the operability of the instruction again based on the first working instruction;

[0036] If the operability of the instruction is greater than 1, then the first working instruction is determined to be operable, and the bucket wheel excavator is controlled to perform intelligent coal feeding based on the first working instruction.

[0037] Conversely, if the current bucket wheel excavator malfunctions, then fault detection, prompts, and troubleshooting will be performed.

[0038] In one possible implementation, the current bucket wheel excavator is identified as malfunctioning, and fault detection, alerts, and troubleshooting are performed, including:

[0039] Step 421: Transmit instructions with an operability of no more than 1 to the bucket wheel excavator fault management terminal, and collect real-time equipment information of the bucket wheel excavator based on the fault management terminal;

[0040] Step 422: Based on the equipment information and the corresponding instructions, obtain the fault index corresponding to the current bucket wheel excavator, and then make a fault judgment;

[0041] If the fault index is less than the first preset range, then the fault of the bucket wheel excavator is determined to be a bucket wheel excavator equipment fault.

[0042] If the bucket wheel excavator malfunction is classified as a bucket wheel excavator equipment malfunction, the malfunction index is compared with the malfunction analysis table to determine the equipment malfunction level of the bucket wheel excavator.

[0043] If the equipment failure level of the bucket wheel excavator is Level 1, then the bucket wheel excavator is currently in a minor fault condition and can continue to be used. The operating parameters of the bucket wheel excavator can be adjusted based on the current fault condition, thereby enabling intelligent coal feeding based on the adjusted operating parameters.

[0044] If the equipment fault level of the bucket wheel excavator is not at the first level, the actual working parameters of the bucket wheel excavator will be transmitted to the bucket wheel excavator fault management terminal to provide a fault prompt.

[0045] If the fault index is not less than the first preset range, the fault of the bucket wheel excavator is determined to be a fault of the parameter acquisition equipment, and the equipment is inspected and alerted.

[0046] Step 424: Analyze the fault prompts based on the fault management terminal to troubleshoot the fault.

[0047] In one possible implementation, determining that the fault of the bucket wheel excavator is a fault of the parameter acquisition equipment, and then detecting and alerting the equipment, including:

[0048] If the current fault of the bucket wheel excavator is due to a fault in the parameter acquisition equipment, then all parameter acquisition equipment should be classified.

[0049] Compare the same parameters obtained by the same type of equipment based on the same type of parameters;

[0050] Determine whether the deviation value of the current parameter is greater than the preset deviation range based on the comparison results between the same type of parameters;

[0051] If the deviation is greater than the preset deviation range, the device number of the device will be obtained by filtering out the parameters corresponding to the parameters with large deviations.

[0052] The device number and corresponding parameter values ​​are transmitted to the fault management terminal, and a fault prompt is given.

[0053] Conversely, if the parameter acquisition device corresponding to the current parameter is not faulty, the remaining parameters are checked until the faulty parameter acquisition device is found, and the device number and corresponding parameter value are transmitted to the fault management terminal, and a fault prompt is issued.

[0054] This invention provides an intelligent coal feeding system for bucket wheel excavators, comprising:

[0055] Parameter acquisition module: Real-time acquisition of key stacking parameters and key coal parameters of the current target coal pile;

[0056] Parameter determination module: Based on the key stacking parameters uploaded to the intelligent management terminal of the bucket wheel excavator, the first working attribute parameters of the bucket wheel excavator are determined;

[0057] Parameter adjustment module: Adjusts the first working attribute parameters of the bucket wheel excavator based on the key coal parameters to obtain the second working attribute parameters, and issues the original working command based on the second working attribute parameters;

[0058] Control optimization module: Determines the operability of the original work instruction. If operable, it controls the bucket wheel excavator to intelligently feed coal based on the original work instruction. Otherwise, it optimizes the original work instruction based on the intelligent management terminal.

[0065] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0066] Example 1:

[0067] This invention provides an intelligent coal feeding method for bucket wheel excavators, such as... Figure 1 As shown, it includes:

[0068] Step 1: Obtain key parameters of the current target coal pile and key parameters of the coal in real time;

[0069] Step 2: Based on the stacking key parameters, upload them to the intelligent management terminal of the bucket wheel excavator to determine the first working attribute parameters of the bucket wheel excavator;

[0070] Step 3: Adjust the first working attribute parameters of the bucket wheel excavator based on the key coal parameters to obtain the second working attribute parameters, and issue the original working command based on the second working attribute parameters;

[0071] Step 4: Determine the operability of the original work instruction. If it is operable, control the bucket wheel excavator to intelligently feed coal based on the original work instruction. Otherwise, optimize the original work instruction based on the intelligent management terminal.

[0072] In this embodiment, the target coal pile refers to the portion of the coal pile that requires coal loading using a bucket wheel excavator.

[0073] In this embodiment, the key parameters of stacking refer to the key parameters among the stacking parameters of the target coal pile that will affect the coal loading of the bucket wheel excavator. For example, the key parameters of stacking include the inclination, height, bottom area, and top area of ​​the target coal pile.

[0074] In this embodiment, key coal parameters refer to the key parameters among the coal parameters of the target coal pile that will affect the coal loading of the bucket wheel excavator. For example, key coal parameters include the moisture content, calorific value, and caking index of the target coal pile.

[0075] In this embodiment, the first working attribute parameter refers to the working parameters for normal operation of the bucket wheel excavator determined based on the key parameters of the target coal pile. For example, if the height of the coal pile is 20 meters and the depth of one bucket of the bucket wheel excavator is 2 meters, then one of the working attribute parameters of the bucket wheel excavator is a height of 18 meters.

[0076] In this embodiment, the second working attribute parameter refers to the working parameter of the bucket wheel excavator after adjusting the first working attribute parameter based on the key coal parameters of the target coal pile. For example, if the adhesion index of the target coal pile in the key coal parameters is 1.2, then the bucket wheel running speed of the bucket wheel excavator is 0.8 times the normal speed.

[0077] In this embodiment, the original working instruction refers to the working instruction issued to the bucket wheel machine based on the parameter conditions of the second working attribute parameter, such as raising the bucket wheel height to a position of 18 meters.

[0078] In this embodiment, operability refers to the operability of the original work instructions. For example, if there is an error in the stacking key parameters, it may cause problems in the calculation of the work attribute parameters, and the operability of the corresponding original work instructions will be relatively low.

[0079] The beneficial effects of the above technical solution are: by determining the working attribute parameters of the bucket wheel excavator through the stacking parameters of the target coal pile, and adjusting them based on the key parameters of the coal, the obtained working attribute parameters can be more accurate; and by optimizing the original working instructions based on operability, the issued working instructions can be more precise.

[0080] Example 2:

[0081] Based on Example 1, the key parameters of the current target coal pile and the key parameters of the coal are acquired in real time, including:

[0082] Step 11: Measure the stacking parameters of the target coal pile from all angles using preset instruments and transmit the data to the parameter management terminal in real time;

[0083] Step 12: Based on the historical data of the parameter management terminal, select the available parameters from the stacking parameters as the key stacking parameters for the target coal pile;

[0084] Step 13: Collect and test coal samples from several areas of the target coal pile using the preset coal quality testing tools, obtain the key parameters of the coal in the target coal pile, and upload them to the parameter management terminal.

[0085] In this embodiment, the preset instruments include a level, an infrared measuring instrument, and sensors.

[0086] In this embodiment, the target coal pile refers to the portion of the coal pile that requires coal loading using a bucket wheel excavator.

[0087] In this embodiment, the stacking parameters refer to all measurable parameters of the target coal pile as measured by a preset instrument.

[0088] In this embodiment, historical data refers to the historical stacking parameters stored in the database of the parameter management terminal.

[0089] In this embodiment, the key parameters of stacking refer to the key parameters among the stacking parameters of the target coal pile that will affect the coal loading of the bucket wheel excavator. That is, all available parameters in the stacking parameters of the target coal pile. For example, the key parameters of stacking include the inclination, height, bottom area, and top area of ​​the target coal pile.

[0090] In this embodiment, the coal quality testing tool includes a sensor, a sampler, and a coal quality identification detector.

[0091] In this embodiment, the coal sample refers to the sample obtained after sampling at different heights and depths of the target coal pile.

[0092] In this embodiment, key coal parameters refer to the key parameters among the coal parameters of the target coal pile that will affect the coal loading of the bucket wheel excavator. For example, key coal parameters include the moisture content, calorific value, and caking index of the target coal pile.

[0093] The beneficial effects of the proposed technical solution are: by obtaining and screening the stacking parameters, key stacking parameters are obtained, thereby determining the working attribute parameters of the bucket wheel excavator, and adjustments are made based on the key coal parameters, which can make the obtained working attribute parameters more accurate.

[0094] Example 3:

[0095] Based on Example 2, the key stacking parameters are uploaded to the intelligent management terminal of the bucket wheel excavator to determine the first working attribute parameters of the bucket wheel excavator, including:

[0096] Step 20: Based on the obtained key parameters of the target coal pile and key parameters of the coal, perform data preprocessing to obtain the first key parameters of the pile and the first key parameters of the coal.

[0097] Step 21: Determine the key parameters of the first stacking;

[0098] If there are no error parameters in the first stacking key parameters, then retain the current first stacking key parameters;

[0099] Conversely, if the current key parameters for the first pile are not found, the pile parameters for the target coal pile are collected again.

[0100] Step 22: The intelligent management terminal based on the bucket wheel excavator identifies and detects the first key stacking parameters that are retained, thereby determining the first working attribute parameters of the bucket wheel excavator.

[0101] In this embodiment, data preprocessing refers to the unit unification and data standardization of the key parameters of the target coal pile and the key parameters of the coal.

[0102] In this embodiment, the first key stacking parameter and the first key coal parameter refer to the key stacking parameter and the key coal parameter after data preprocessing.

[0103] In this embodiment, the error parameter refers to the parameter in the stacking parameters that has a large error compared to other corresponding parameters. For example, if the bottom area of ​​the target coal pile is 80 square meters and the top area is also 80 square meters, then there is an error in the acquisition of the area parameter, which is the error parameter.

[0104] In this embodiment, the first working attribute parameter refers to the working parameters for normal operation of the bucket wheel excavator determined based on the key parameters of the target coal pile. For example, if the height of the coal pile is 20 meters and the depth of one bucket of the bucket wheel excavator is 2 meters, then one of the working attribute parameters of the bucket wheel excavator is a height of 18 meters.

[0105] The beneficial effect of the proposed technical solution is that by judging the key parameters of the target coal pile, the working attribute parameters of the bucket wheel excavator can be determined, and adjustments can be made based on the key parameters of the coal, so that the obtained working attribute parameters can be more accurate.

[0106] Example 4:

[0107] Based on Embodiment 3, the intelligent management terminal of the bucket wheel excavator identifies and detects the retained first key stacking parameters to determine the first working attribute parameters of the bucket wheel excavator, including:

[0108] Step 221: The intelligent management terminal based on the bucket wheel excavator identifies the first stacking key parameters that have been retained, and fills each parameter of the first stacking key parameters into the corresponding position of the key parameter table based on the identification results;

[0109] Step 222: Calculate the filling results of the filled part of the key parameter table to obtain the first original working attribute parameters of the bucket wheel excavator corresponding to the first stacking key parameters;

[0110] The unfilled parts in the key parameter table are filled in based on the corresponding standard parameters, and then combined with the first original working attribute parameters to obtain the first working attribute parameters of the bucket wheel excavator.

[0111] In this embodiment, the first stacking key parameter refers to the stacking key parameter after data preprocessing.

[0112] In this embodiment, the key parameter table refers to the table corresponding to the first stacking key parameters, wherein the first column of the key parameter table represents the parameter attribute and the second column represents the parameter attribute value.

[0113] In this embodiment, the first original working attribute parameter refers to the working parameters for normal operation of the bucket wheel excavator determined based on the key parameter table of the filled portion.

[0114] In this embodiment, the first working attribute parameter refers to the working parameters for normal operation of the bucket wheel machine determined based on the key parameter table filled with the key parameters of the target coal pile and the standard parameter values ​​of the unfilled parts. For example, if the height of the coal pile is 20 meters and the depth of one bucket of the bucket wheel machine is 2 meters, based on the key parameters of the target coal pile, then one of the working attribute parameters of the bucket wheel machine is a height of 18 meters.

[0115] The beneficial effects of the proposed technical solution are: by processing the key parameters of the target coal pile and adjusting them based on the standard parameter values ​​in the key parameter table, the working attribute parameters of the bucket wheel excavator can be determined, and by adjusting them based on the key parameters of the coal, the obtained working attribute parameters can be made more accurate.

[0116] Example 5:

[0117] Based on Example 3, the first working attribute parameters of the bucket wheel excavator are adjusted according to the key coal parameters to obtain the second working attribute parameters. Based on the second working attribute parameters, the original working instructions are issued, such as... Figure 2 As shown, it includes:

[0118] Step 31: Determine the coal quality of the target coal pile based on the first key coal parameters, and compare it with the preset quality table to obtain the quality grade of the target coal pile;

[0119] Step 32: Compare the standard working attribute parameters corresponding to the quality level with the first working attribute parameters, calculate the executability of the first working attribute parameters, and obtain the second working attribute parameters;

[0120] If the executability of the first working attribute parameter is less than the preset executability, then the first working attribute parameter is adjusted based on the standard working attribute parameter to obtain the second working attribute parameter.

[0121] Conversely, the first working attribute parameter is used as the second working attribute parameter;

[0122] Step 33: Use the second working attribute parameter as the original working parameter of the bucket wheel excavator and issue the original working command.

[0123] In this embodiment, coal quality refers to the quality of coal obtained based on the first key coal parameter. For example, the target coal pile is determined to be mainly coking coal based on the first key coal parameter, thereby determining the quality range of the target coal pile.

[0124] In this embodiment, the quality grade refers to the coal grade in the coal database based on the coal quality. For example, the coal quality corresponding to prime coking coal is B+.

[0125] In this embodiment, the standard working attribute parameters refer to the working attribute parameters of the bucket wheel excavator based on the coal quality grade corresponding to the target coal pile.

[0126] In this embodiment, the first working attribute parameter refers to the working parameters for normal operation of the bucket wheel machine determined based on the key parameter table filled with the key parameters of the target coal pile and the standard parameter values ​​of the unfilled parts. For example, if the height of the coal pile is 20 meters and the depth of one bucket of the bucket wheel machine is 2 meters, based on the key parameters of the target coal pile, then one of the working attribute parameters of the bucket wheel machine is a height of 18 meters.

[0127] In this embodiment, executability refers to the executability of the first working attribute parameter determined based on the comparison result after comparing the first working attribute parameter with the standard working attribute parameter.

[0128] In this embodiment, the second working parameter refers to the working parameter for normal operation of the bucket wheel excavator obtained by adjusting the first working attribute parameter based on the key coal parameters of the target coal pile. For example, if the adhesion index of the target coal pile in the key coal parameters is 1.2, then the bucket wheel running speed of the bucket wheel excavator is 0.8 times the normal speed.

[0129] In this embodiment, the preset executability refers to the preset executability determined in advance based on the comparison results of historical first working attribute parameters and standard working attribute parameters. The more historical first working attribute parameters are referenced, the more accurate the preset executability will be.

[0130] In this embodiment, the first adjustment is to adjust the corresponding parameters in the first working attribute parameters based on the parameters in the standard working attribute parameters. The first adjustment mainly involves adjusting the first working attribute parameter part corresponding to the standard parameter value in the key parameter table.

[0131] In this embodiment, the original working instruction refers to the working instruction issued to the bucket wheel machine based on the parameter conditions of the second working attribute parameter, such as raising the bucket wheel height to a position of 18 meters.

[0132] The beneficial effects of the above technical solution are: by adjusting the first working attribute parameters of the bucket wheel excavator using key coal parameters, the obtained working attribute parameters can be more accurate, and by optimizing the original working instructions based on operability, the issued working instructions can be more precise.

[0133] Example 6:

[0134] Based on Example 5, the operability of the original work instruction is determined. If operable, the bucket wheel excavator is controlled to intelligently feed coal based on the original work instruction; otherwise, the original work instruction is optimized based on the intelligent management terminal, including:

[0135] Step 41: Based on the original work instructions, combined with real-time environmental factors, bucket wheel excavator equipment wear factors, and external factors, determine the operability of the instructions on the intelligent management terminal of the bucket wheel excavator;

[0136]

[0137] Among them, T i M represents the operability of the i-th instruction in the current work instruction; i α is the instruction value corresponding to the i-th instruction; i αi represents the historical average parameter value of the i-th work instruction under different real-time environmental factors; αj represents the parameter value corresponding to the j-th real-time environmental factor; αj s β1, β2, and β3 are the standard average parameter values ​​of the i-th work instruction under different standard environmental factors; β1, β2, and β3 are the weighted influence coefficients of real-time environmental factors, bucket wheel excavator equipment wear factors, and external factors; η is the bucket wheel excavator equipment wear index; η s δ represents the standard failure index of the bucket wheel excavator; m represents the total number of real-time environmental factors;

[0138] If the operability of the instruction is greater than 1, then the original work instruction is determined to be operable, and the bucket wheel excavator is controlled to perform intelligent coal feeding based on the original work instruction.

[0139] Conversely, the second working attribute parameter is adjusted based on the external factors to obtain the third working attribute parameter, and the first working instruction is obtained based on the third working attribute parameter.

[0140] Step 42: Determine the operability of the instruction again based on the first working instruction;

[0141] If the operability of the instruction is greater than 1, then the first working instruction is determined to be operable, and the bucket wheel excavator is controlled to perform intelligent coal feeding based on the first working instruction.

[0142] Conversely, if the current bucket wheel excavator malfunctions, then fault detection, prompts, and troubleshooting will be performed.

[0143] In this embodiment, operability is obtained by adjusting the corresponding instruction value.

[0144] In this embodiment, the original working instruction refers to the working instruction issued to the bucket wheel machine based on the parameter conditions of the second working attribute parameter, such as raising the bucket wheel height to a position of 18 meters.

[0145] In this embodiment, real-time environmental factors refer to environmental factors that affect the operation of the bucket wheel excavator, such as rain, snow, and strong winds.

[0146] In this embodiment, the equipment wear factors of the bucket wheel excavator refer to the equipment wear that exists during the operation of the bucket wheel excavator, such as the wear of the rotating bearings of the bucket wheel excavator.

[0147] In this embodiment, external factors refer to factors that cause malfunctions in the bucket wheel excavator under abnormal circumstances, such as human sabotage.

[0148] In this embodiment, operability refers to the operability of the original work instructions. For example, if there is an error in the stacking key parameters, it may cause problems in the calculation of the work attribute parameters, and the operability of the corresponding original work instructions will be relatively low.

[0149] In this embodiment, the second adjustment refers to adjusting the second working attribute parameters of the bucket wheel machine based on the influence parameters corresponding to external factors.

[0150] In this embodiment, the third working attribute parameter refers to the working attribute parameter obtained by adjusting the second working attribute parameter based on external factors.

[0151] In this embodiment, the first working instruction refers to the working instruction issued to the bucket wheel machine based on the parameter conditions of the third working attribute parameter, such as raising the bucket wheel height to a position of 18.2 meters.

[0152] In this embodiment, fault detection refers to determining that the bucket wheel machine is faulty if the first working command of the bucket wheel machine is also not operable, and then detecting the equipment that may be faulty.

[0153] The beneficial effects of the above technical solution are: by combining the original working instructions of the bucket wheel excavator with real-time external factors, the operability of the original working instructions can be determined, and the original working instructions can be optimized based on the operability, making the issued working instructions more accurate.

[0154] Example 7:

[0155] Based on Example 6, a fault is determined to be present in the current bucket wheel excavator, and fault detection, prompting, and troubleshooting are performed, including:

[0156] Step 421: Transmit instructions with an operability of no more than 1 to the bucket wheel excavator fault management terminal, and collect real-time equipment information of the bucket wheel excavator based on the fault management terminal;

[0157] Step 422: Based on the equipment information and the corresponding instructions, obtain the fault index corresponding to the current bucket wheel excavator, and then make a fault judgment;

[0158] If the fault index is less than the first preset range, then the fault of the bucket wheel excavator is determined to be a bucket wheel excavator equipment fault.

[0159] If the bucket wheel excavator malfunction is classified as a bucket wheel excavator equipment malfunction, the malfunction index is compared with the malfunction analysis table to determine the equipment malfunction level of the bucket wheel excavator.

[0160] If the equipment failure level of the bucket wheel excavator is Level 1, then the bucket wheel excavator is currently in a minor fault condition and can continue to be used. The operating parameters of the bucket wheel excavator can be adjusted based on the current fault condition, thereby enabling intelligent coal feeding based on the adjusted operating parameters.

[0161] If the equipment fault level of the bucket wheel excavator is not at the first level, the actual working parameters of the bucket wheel excavator will be transmitted to the bucket wheel excavator fault management terminal to provide a fault prompt.

[0162] If the fault index is not less than the first preset range, the fault of the bucket wheel excavator is determined to be a fault of the parameter acquisition equipment, and the equipment is inspected and alerted.

[0163] Step 424: Analyze the fault prompts based on the fault management terminal to troubleshoot the fault.

[0164] In this embodiment, operability refers to the operability of the original work instructions. For example, if there is an error in the stacking key parameters, it may cause problems in the calculation of the work attribute parameters, and the operability of the corresponding original work instructions will be relatively low.

[0169] In this embodiment, the equipment failure level refers to the degree of failure of the bucket wheel excavator. For example, it can be divided into five levels, namely level one to level five failures, or it can be divided into three levels, namely minor failure, major failure and major failure.

[0170] In this embodiment, the adjusted working parameters refer to the working attribute parameters obtained by adjusting the corresponding calculation method from key coal parameters and key stacking parameters to working attribute parameters based on the current equipment status of the bucket wheel excavator when it is under slight thumping conditions.

[0172] In this embodiment, troubleshooting refers to performing intelligent analysis based on the fault prompt content to determine the cause of the fault and the equipment, and then troubleshooting.

[0174] Example 8:

[0175] Based on Example 7, it is determined that the fault of the bucket wheel excavator is a fault of the parameter acquisition equipment. The equipment is then inspected and alerted, including:

[0176] If the current fault of the bucket wheel excavator is due to a fault in the parameter acquisition equipment, then all parameter acquisition equipment should be classified.

[0177] Compare the same parameters obtained by the same type of equipment based on the same type of parameters;

[0178] Determine whether the deviation value of the current parameter is greater than the preset deviation range based on the comparison results between the same type of parameters;

[0179] If the deviation is greater than the preset deviation range, the device number of the device will be obtained by filtering out the parameters corresponding to the parameters with large deviations.

[0180] The device number and corresponding parameter values ​​are transmitted to the fault management terminal, and a fault prompt is given.

[0181] Conversely, if the parameter acquisition device corresponding to the current parameter is not faulty, the remaining parameters are checked until the faulty parameter acquisition device is found, and the device number and corresponding parameter value are transmitted to the fault management terminal, and a fault prompt is issued.

[0182] In this embodiment, the parameter acquisition device refers to the device that acquires the stockpiling parameters and key parameters of the coal.

[0183] In this embodiment, the device for acquiring similar parameters refers to a device that measures similar parameters. For example, a device that measures the bottom area and top area of ​​a coal pile is a device for acquiring similar parameters.

[0184] In this embodiment, the same type of parameter refers to parameters with the same parameter type.

[0185] In this embodiment, the parameter deviation value refers to the deviation value between the same type of parameter.

[0186] In this embodiment, the preset deviation value refers to the maximum deviation value that can exist among the same parameter obtained by several devices. The preset deviation value is generally no greater than 0.3.

[0187] In this embodiment, the device number generally includes the location of the parameter acquisition device around or inside the target coal pile.

[0188] The beneficial effects of the above technical solution are: by accurately judging the fault of the parameter acquisition equipment, the faulty equipment can be replaced in a timely manner, thereby making the parameter acquisition more accurate, which in turn increases the operability of the bucket wheel excavator's working instructions and makes the issued working instructions more precise.

[0189] Example 9:

[0190] This invention provides an intelligent coal feeding system for bucket wheel excavators, such as... Figure 3 As shown, it includes:

[0191] Parameter acquisition module: Real-time acquisition of key stacking parameters and key coal parameters of the current target coal pile;

[0192] Parameter determination module: Based on the key stacking parameters uploaded to the intelligent management terminal of the bucket wheel excavator, the first working attribute parameters of the bucket wheel excavator are determined;

[0193] Parameter adjustment module: Adjusts the first working attribute parameters of the bucket wheel excavator based on the key coal parameters to obtain the second working attribute parameters, and issues the original working command based on the second working attribute parameters;

[0194] Control optimization module: Determines the operability of the original work instruction. If operable, it controls the bucket wheel excavator to intelligently feed coal based on the original work instruction. Otherwise, it optimizes the original work instruction based on the intelligent management terminal.

[0195] The beneficial effects of the above technical solution are: by determining the working attribute parameters of the bucket wheel excavator through the stacking parameters of the target coal pile, and adjusting them based on the key parameters of the coal, the obtained working attribute parameters can be more accurate; and by optimizing the original working instructions based on operability, the issued working instructions can be more precise.

Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
