Description

Technical Field

[0001] The present invention relates to the technical field of mine production and management and control, and in particular to an open-pit mine safety production and management and control system based on full-time and space elements. Background Art

[0002] Mine production and management are core aspects of mining resource extraction. Their goal is to achieve safe and efficient production by optimizing resource allocation and coordinating equipment operations in real time. However, existing technologies still have significant shortcomings in multi-system collaboration, dynamic response, and intelligent decision-making.

[0003] The current existing technology in China, patent publication number: CN117787582A, provides an ore vehicle loading scheduling optimization method based on an improved particle swarm algorithm. This technical solution obtains basic mine information and then imports it into mine-related three-dimensional software to generate a mine texture report and calculate the mine storage volume. Then, the basic parameters of the mining equipment are input, and the average mining volume of the mining equipment is calculated to optimize the input of surrounding mine vehicles. In this way, the acquisition, storage, transmission, and deep processing of mine information are achieved, and various production indicator data are collected in real time, thereby solving the problems of dynamic management of mine production and mine production planning. The technical solution involves obtaining basic mine information and building relevant three-dimensional mine software to determine the mine storage volume, as well as obtaining the basic parameters of the mining equipment and optimizing the surrounding mining vehicles, thereby solving the dynamic management of mine production.

[0027] Furthermore, the intelligent analysis module is also used to determine to reduce the preset engine power based on the comparison result between the dust concentration and the preset dust concentration, and the reduction range of the preset engine power is proportional to the dust concentration.

[0028] Furthermore, the intelligent analysis module is further configured to determine, based on a comparison result of the abnormal power variance with a preset abnormal power variance, why the construction of the production plan does not meet the standards and generate corresponding instructions based on the reasons, and determine corresponding processing based on the instructions, including: re-determining corresponding processing based on a comparison result of the average excavation distance with a preset average excavation distance, increasing a filter window length in a preprocessing process, or issuing a maintenance notice for the mining equipment;

[0032] The excavation distance difference is the difference between the average excavation distance and the preset average excavation distance.

[0033] Furthermore, the intelligent analysis module is further configured to determine, based on a comparison result of the vibration velocity mean value with a preset vibration velocity mean value, whether to increase the filter window length, and the increase in the filter window length is proportional to the vibration velocity mean value;

[0035] Compared with the existing technology, the beneficial effect of the open-pit mine production safety and management system based on full-time and space elements of the present invention is that the system obtains mine geographic information and ore resource distribution information as well as the location information of several mining equipment in the mine through the production scheduling module, and constructs a production plan based on the information; generates and sends real-time control signals to the corresponding mining equipment through the collaborative control module, and periodically collects the engine power of several mining equipment; transmits the production plan constructed by the production scheduling module to the collaborative control module through the integration connection module, so that the collaborative control module generates real-time control signals based on the production plan; obtains the engine power corresponding to several mining equipment through the intelligent analysis module and compares it with the preset engine power to determine whether the construction process of the production plan meets the standards, and determines the cause when it is determined that the construction process does not meet the standards, generates corresponding instructions based on the cause, determines the corresponding correction processing method based on the instructions, and then adjusts the various parameters in the production plan to improve the production efficiency of the mine.

[0040] Furthermore, when the present invention determines that the filter window length in the preprocessing process needs to be increased based on the comparison between the abnormal power variance and the preset abnormal power variance, the increase range of the filter window length can be determined based on the comparison between the vibration velocity mean and the preset vibration velocity mean, thereby improving the system's preprocessing capability for data, reducing data abnormalities, and thus optimizing the system's data processing process.

[0052] The spatiotemporal data acquisition unit is used to collect a number of data information, wherein the data information includes the mine geographic information, the ore resource distribution information, the mining equipment location information and the dust concentration information; the spatiotemporal data processing unit is connected to the spatiotemporal data acquisition unit, and is used to perform standardization processing on the several data information to obtain standardized data information, and to perform time stamping on the standardized data information; the spatiotemporal data storage construction unit is connected to the spatiotemporal data processing unit, and is used to classify the several standardized data information to obtain geographic information, resource distribution information and equipment location information, and to construct a hierarchical data storage architecture based on the geographic information, resource distribution information and equipment location information; the production plan construction unit is connected to the spatiotemporal data storage construction unit, and is used to construct the production plan based on the hierarchical data storage architecture.

[0053] Specifically, in this embodiment, the production scheduling module includes a spatiotemporal data acquisition unit, a spatiotemporal data processing unit, a spatiotemporal data storage construction unit and a production plan construction unit; the spatiotemporal data processing unit is connected to the spatiotemporal data acquisition unit and the spatiotemporal data storage construction unit respectively, and the spatiotemporal data storage construction unit is connected to the production plan construction unit.

[0054] Among them, the spatiotemporal data acquisition unit includes several different types of sensors, and several sensors are set at corresponding positions of the mine and several mining equipment. The signals emitted by each sensor are used to obtain the actual parameters of the mine, the location information of each mining equipment in the mine, and the dust concentration information generated by the mining equipment when mining ore; wherein, the actual parameters of the mine include mine geographic information and ore resource distribution information; specifically, several different types of sensors include geographic information sensors, resource distribution sensors, GPS receivers and environmental monitoring sensors; wherein, the geographic information sensor can accurately obtain the topography of the mine by using a three-dimensional laser scanner to determine the geographic information of the mine, the GPS receiver can determine the specific geographical point position of the mining equipment in the mine, the resource distribution sensor can detect the resource distribution status of different areas of the mine by using ore grade sensors and reserve detection radars, and the environmental monitoring sensor can determine the dust concentration corresponding to the area where each mining equipment is located when the ore is mined by using air quality monitoring sensors.

[0055] Among them, the spatiotemporal data processing unit includes a data format automatic identification and conversion engine, which uses the data format automatic identification and conversion engine to convert the format of several data information obtained by the sensor and automatically convert it into a standardized data format uniformly adopted in the system to obtain standardized data information. The standardized data information has good readability and versatility, which provides convenience for subsequent data processing processes; then the standardized data information is time-stamped to complete the spatiotemporal coordinate assignment for several data information, and provide spatiotemporal positioning of ores, equipment, etc. in the subsequent production scheduling process, so as to facilitate the rapid acquisition of corresponding data information; among them, the standardized data information includes several mine geographic information, ore resource distribution information and mining equipment location information.

[0056] Among them, the spatiotemporal data storage construction unit can classify a number of data information according to their sources and their own characteristics or obtain geographical information, resource distribution information and equipment location information; then build a basic layer based on geographical information, build a resource layer based on resource distribution information, and build a dynamic layer based on equipment location information, thereby forming a layered data storage architecture, distributing and storing a number of data information on different storage nodes, and performing data backup operations regularly to prevent a number of data information from being lost due to hardware failure, natural disasters or human operation. Among them, the topography, slope and direction, and geological structure data of the mine are divided out through geographical information to determine the terrain undulation and fault direction of the mine, the ore reserve scale and ore grade information of different areas are determined through resource distribution information, and the location and quantity of a number of mining equipment in different areas of the mine are determined through equipment location information, and subsequent production plans can be constructed based on this.

[0057] Among them, the production construction unit can use artificial intelligence algorithms to build a production plan based on a hierarchical data storage architecture and combined with production tasks; among them, artificial intelligence algorithms include decision trees and neural networks, and production tasks include ore mining volume targets, etc.

[0058] In this embodiment, a multi-level index is further established based on the base layer, resource layer, and dynamic layer, such as a spatial grid index on the base layer, a spatial and resource attribute index on the resource layer, and a time and device ID index on the dynamic layer, to improve the efficiency of data retrieval, thereby more efficiently constructing a production plan. In other embodiments, indoor positioning technology can be used instead of a GPS receiver. Indoor positioning technology can use Bluetooth Low Energy (BLE), ultra-wideband (UWB), and other means to obtain the specific geographic location of mining equipment in a mine in an indoor environment or in an area with limited GPS signals, thereby ensuring accurate acquisition of mining equipment location information.

[0059] See also Figure 3As shown in FIG, it is a schematic diagram of the collaborative control module in this embodiment. The collaborative control module includes a device control unit, a device data transmission unit, a device data acquisition unit, and a device data processing unit, wherein:

[0060] The equipment control unit is connected to the production plan construction unit to generate a real-time control signal based on the production plan; the equipment data transmission unit is respectively connected to the equipment control unit and several of the mining equipment to obtain the real-time control signal and transmit it to the corresponding mining equipment; the equipment data acquisition unit is connected to several of the mining equipment to periodically collect the engine power of each mining equipment; the equipment data processing unit is connected to the equipment data acquisition unit to obtain several of the engine powers and perform data preprocessing to obtain the processed engine power.

[0061] Specifically, in this embodiment, the collaborative control module includes an equipment control unit, an equipment data transmission unit, several engine power sensors, an equipment data acquisition unit and an equipment data processing unit; the equipment control unit is connected to the production plan construction unit through an integrated connection module, the equipment data transmission unit is respectively connected to the equipment control unit and several mining equipment, and the equipment data acquisition unit is respectively connected to several mining equipment and the equipment data processing unit.

[0062] Among them, the equipment control unit includes a control signal generation center, which can transmit the production plan generated by the production plan construction unit to the control signal generation center through the integrated connection module, and then analyze the production plan and generate corresponding real-time control signals based on the analysis results.

[0063] Among them, the equipment data transmission unit can obtain the real-time control signal, and then send the real-time control signal to the corresponding mining equipment, thereby realizing the start and stop control of each mining equipment; in order to ensure the security of the data transmission process, the real-time control signal can be encoded and encrypted.

[0064] Among them, an engine power sensor is configured on each mining equipment, and the engine power signal is sent through the engine power sensor. The equipment data acquisition unit receives the engine power signal to complete the periodic collection work.

[0065] Among them, the equipment data processing unit includes a central data processing center, which can obtain several engine powers and then perform data preprocessing. The preprocessing process includes noise reduction processing on the obtained engine power data to reduce the abnormal state of the data, thereby ensuring the accuracy of subsequent analysis. The engine power here refers to the total engine power used when the mining equipment is fully engaged in mining work. In order to ensure subsequent analysis, the power obtained after data collection for each mining equipment can be divided according to the preset engine power. Taking the cutting part of the coal mining machine in the mining equipment as an example, the engine power in the cutting part is between 400 kilowatts and 500 kilowatts (including 500 kilowatts) and is set as Class I mining equipment, the engine power is between 500 kilowatts and 600 kilowatts (including 600 kilowatts) and is set as Class II mining equipment, and the engine power is between 600 kilowatts and 700 kilowatts (including 700 kilowatts) and is set as Class III mining equipment. There are other mining equipment in the future and so on, and the same type of mining equipment can be monitored and judged; after completing the classification of mining equipment, all mining equipment can be divided into several categories. For the same type of mining equipment, the preset engine power is in the same range, such as the preset engine power of Class I mining equipment is set to 500 kilowatts, the preset engine power of Class II mining equipment is set to 600 kilowatts, and the preset engine power of Class III mining equipment is set to 700 kilowatts. The preset engine power is determined based on the production plan.

[0066] Furthermore, the production scheduling module and the collaborative control module are integrated through the integration connection module and data and signals are transmitted between each other to realize data interaction, so that the mining equipment can be controlled in real time through the production plan constructed by the production scheduling module to improve the efficiency of intelligent production management of mines.

[0067] See also Figure 4 As shown, it is a flow chart of the method of applying the open-pit mine safety production and management system based on full-time and space elements in this embodiment. The process includes at least the following steps:

[0068] S1: Obtaining actual mine parameters and location information of several mining equipment in the mine through a production scheduling module, and building a production plan based on the actual mine parameters and location information of the mining equipment, wherein the actual mine parameters include mine geographic information and ore resource distribution information.

[0069] S2: Generate and send real-time control signals to the corresponding mining equipment through the collaborative control module, and periodically obtain the engine power of the mining equipment.

[0070] S3: The production plan is transmitted to the collaborative control module by connecting the integration connection module with the production scheduling module and the collaborative control module respectively, so that the collaborative control module generates the real-time control signal based on the production plan.

[0071] S4: Obtain the engine power through an intelligent analysis module connected to the collaborative control module and determine whether the construction of the production plan meets the standards based on the engine power, and generate corresponding instructions based on the determined reasons when it is determined that the construction of the production plan does not meet the standards.

[0072] S5: Obtain the instruction through the adjustment module connected to the intelligent analysis module, the production scheduling module and the coordinated control module respectively, and determine the preset engine power or issue a maintenance notice for the mining equipment based on the instruction.

[0073] See also Figure 5 As shown, this is a logical decision diagram for determining whether the production plan construction process meets the standards based on the absolute power value in this embodiment. The intelligent analysis module is further configured to make a determination based on the comparison result of the absolute power value with a preset absolute power value, or to draw a dust change curve based on the obtained dust concentration information and re-determine whether the construction of the production plan meets the standards based on the dust change curve. If the intelligent analysis module determines that the construction of the production plan does not meet the standards, it determines the reason for non-compliance based on the difference between the absolute power value and the preset absolute power value. The absolute power value is the absolute value of the difference between the average engine power of the plurality of mining equipment and the preset engine power.

[0074] Specifically, in this embodiment, an analysis is performed using a rated power of 500 kilowatts for a type of mining equipment. The engine power of each mining equipment in the same type of mining equipment is obtained, and then the average power value is calculated. The absolute value of the difference between the average power value and the preset engine power is then calculated. In order to more accurately determine the determination result, the preset power absolute value F0 can be divided into a first preset power absolute value F1 and a second preset power absolute value F2. The preset power absolute value standard F3 is set to 45 kilowatts, F1 = F3-5, and F2 = F3+5. It should be noted that F1, F2, and F3 can also be adjusted according to relevant parameters. The specific process of comparing the power absolute value F with F1 and F2 is as follows:

[0075] If the absolute power value F is less than or equal to the first preset absolute power value F1, the current absolute power value is relatively small, within the 10% instantaneous power fluctuation allowed by the cutting unit. Therefore, it can be determined that the engine power of each mining device within the same type of mining equipment is not much different from the preset engine power. In other words, the vast majority of mining devices can operate normally as expected in the production plan, and therefore the production plan is determined to be in compliance with the standards. The minimum absolute power value F is greater than 0.

[0076] If the power absolute value F is greater than the first preset power absolute value F1 and less than or equal to the second preset power absolute value F2, it is impossible to accurately determine the difference between the engine power of each mining equipment and the corresponding preset engine power based on the power absolute value F. Then, a new judgment can be made based on obtaining some dust concentration information. A dust change curve can be drawn based on some dust concentration information and the area where the corresponding mining equipment is located, and based on this curve, it can be further determined whether the construction of the production plan meets the standards.

[0077] If the absolute power value F is greater than the second preset absolute power value F2, it indicates that the current absolute power value is relatively large. Therefore, it can be determined that the engine power of most mining equipment of the same type differs significantly from the preset engine power. In other words, most mining equipment cannot operate normally as expected in the production plan. Therefore, the production plan is determined to be non-compliant. It is clear that the absolute power value F is not an infinite value.

[0078] Furthermore, the intelligent analysis module is also used to determine whether to reduce the preset engine power based on the comparison result of the average value of the dust change slope and the preset average value of the dust change slope; wherein, the average value of the dust change slope is the average value of the curve slopes of the corresponding points of several mining equipment on the dust change curve.

[0079] Specifically, in this embodiment, the mine can be set as a coal mine and machine mining is carried out. The dust monitoring is aimed at the total dust concentration in the area where the machine mining equipment is located. The dust concentration information in the dust change curve is obtained from the same type of mining equipment. First, each dust change slope is obtained from the dust change curve, and then the average value is calculated based on each dust change slope to obtain the dust change slope average value; in the existing technical standards, taking machine mining without dust prevention measures as an example, the mine working face is the dust detection object, and the total dust concentration range standard of the working face can reach 1000-3000mg / m 3 In this embodiment, the dust concentration range of the area where a single mining device is located during machine mining in the mine can be set to 1000-1500 mg / m 3; Set the preset dust change slope average value V0 = 80. It should be noted that V0 can be calculated based on relevant parameters to obtain other values, and is not specifically limited. The total dust concentration range standard can also use other existing standards as the setting benchmark; the comparison process based on the dust change slope average value V and the preset dust change slope average value V0 is as follows:

[0080] If the average value V of the dust change slope is less than or equal to the preset average value V0 of the dust change slope, it means that the dust concentration generated by the current mining equipment in the area is relatively small. Therefore, if the power absolute value F is greater than the first preset power absolute value F1 and less than or equal to the second preset power absolute value F2, it can be determined that the construction of the production plan does not meet the standards, and the reason for non-compliance with the standards can be determined based on the difference between the power absolute value F and the second preset power absolute value F2.

[0081] If the average value V of the dust change slope is greater than the preset average value V0 of the dust change slope, it means that the dust concentration generated by the current mining equipment in the area is relatively large. Therefore, it can be determined that the situation where the power absolute value F is greater than the first preset power absolute value F1 and less than or equal to the second preset power absolute value F2 is due to the influence of dust concentration. The excessive dust concentration causes deviation in signal acquisition. At this time, the actual engine power of each mining equipment can be reduced by reducing the preset engine power, thereby reducing the dust concentration.

[0082] Furthermore, the intelligent analysis module is also used to determine to reduce the preset engine power based on the comparison result between the dust concentration and the preset dust concentration, and the reduction range of the preset engine power is proportional to the dust concentration.

[0083] Specifically, in this embodiment, taking the engine power of the cutting part of the coal mining machine as an example, the actual engine power of the equipment can be limited by reducing the preset engine power, thereby reducing the engine power during operation, and then reducing the generated dust concentration, thereby avoiding excessive dust from affecting the collection process of the sensor, so as to improve the data collection efficiency of the sensor for the mining location; in order to more accurately adjust the preset engine power, the preset dust concentration N0 can be divided into a first preset dust concentration N1 and a second preset dust concentration N2, and the preset dust concentration standard N3 can be set to 1300 mg / m 3 , N1=N3-100, N2=N3+100. It should be noted that N1, N2 and N3 can also be set to other values according to actual conditions. The setting of N3 is in line with existing technical standards. The comparison process based on dust concentration N with N1 and N2 is as follows:

[0084] Taking the hydraulic traction model as an example; if the dust concentration N is less than or equal to the first preset dust concentration N1 and greater than or equal to 1000 mg / m 3 , the intelligent analysis module generates a first preset power adjustment coefficient instruction, and the adjustment module obtains the first preset power adjustment coefficient instruction to adjust the preset engine power in the intelligent analysis module, reducing the preset engine power to 0.95 times the initial value; if the dust concentration N is greater than the first preset dust concentration N1 and less than or equal to the second preset dust concentration N2, the intelligent analysis module generates a second preset power adjustment coefficient instruction, and the adjustment module obtains the second preset power adjustment coefficient instruction to adjust the preset engine power in the intelligent analysis module, reducing the preset engine power to 0.9 times the initial value; if the dust concentration N is greater than the second preset dust concentration N2 and less than or equal to 1500 mg / m 3 The intelligent analysis module generates a third preset power adjustment coefficient instruction. The adjustment module uses this third preset power adjustment coefficient instruction to adjust the preset engine power in the intelligent analysis module, reducing the preset engine power to 0.85 times the initial value. In this embodiment, the preset engine power reduction factor can also be set to other values, but the maximum reduction is generally no more than 15%, with the goal of effectively reducing dust concentration in the corresponding area without affecting ore mining operations.

[0085] See also Figure 6 As shown, this is a logical decision diagram for determining the reason and correction for the non-standard production plan construction process based on abnormal power variance in this embodiment. The intelligent analysis module is further configured to determine the reason for the non-standard production plan construction process based on the comparison result of the abnormal power variance with the preset abnormal power variance, generate corresponding instructions based on the reason, and determine corresponding processing based on the instructions, including: re-determining the corresponding processing based on the comparison result of the average excavation distance with the preset average excavation distance, increasing the filter window length in the preprocessing process, or issuing a maintenance notice for the mining equipment. The intelligent analysis module is further configured to record as an abnormal equipment any mining equipment whose absolute value of the difference between the engine power and the preset engine power is greater than the preset power absolute value, and to calculate the variance of the engine power of several abnormal equipment to obtain the abnormal power variance. The average excavation distance is the average of several excavation distances acquired by the spatiotemporal data acquisition unit when the mining equipment is mining in the mine.

[0086] Specifically, in this embodiment, taking the cutting part of a coal mining machine in a type of mining equipment as an example, the absolute value of the difference between the engine power and the preset engine power is greater than the second preset power absolute value F2; in order to more accurately determine the cause, the preset abnormal power variance E0 can be divided into a first preset abnormal power variance E1 and a second preset abnormal power variance E2, and the preset abnormal power variance standard E3 is set to 6.9, E1 = 0.97 × E3, and E2 = 1.02 × E3. It should be noted that E1, E2, and E3 can also be set to other values according to changes in relevant parameters; the comparison process based on the abnormal power variance E with E1 and E2 is as follows:

[0087] If the abnormal power variance E is less than or equal to the first preset abnormal power variance E1, the absolute value of the difference between the current engine power of each abnormal device and the preset engine power is relatively close overall. At this point, the spatiotemporal data acquisition unit can be used to obtain the location information of each abnormal device in the mine, and thus the excavation distance of the abnormal device when mining in the corresponding area of the mine. The excavation distance here refers to the shortest straight-line distance between the abnormal device and the spatiotemporal data acquisition unit. The average of several excavation distances is then calculated to obtain the average excavation distance. The corresponding handling method is then re-determined based on the comparison result of the average excavation distance with the preset average excavation distance. In this embodiment, the abnormal power variance E can be greater than or equal to 6.4.

[0088] If the abnormal power variance E is greater than the first preset abnormal power variance E1 and less than or equal to the second preset abnormal power variance E2, it means that the absolute value of the difference between the current engine power of each abnormal device and the preset engine power is between close and dispersed in overall value. At this time, it can be determined that there is a problem in the device data processing unit in the collaborative control module when pre-processing the engine power. The pre-processing process can be adjusted accordingly. In this embodiment, the central data processing center in the device data processing unit uses a sliding average filter to filter the data information. Specifically, the smoothness of the processed engine power can be improved by appropriately increasing the filter window length in the noise reduction process, thereby reducing the abnormality of the data. Among them, the initial setting of the filter window length is determined by the production plan.

[0089] If the abnormal power variance E is greater than the second preset abnormal power variance E2, the absolute values of the differences between the current engine power of each abnormal device and the preset engine power are relatively dispersed overall. Therefore, it can be determined that there is a problem with the abnormal device itself. A preset threshold A = 10 kilowatts is set. If the difference between the engine power of an abnormal device and the preset engine power is greater than A, a maintenance notification is issued for the abnormal device. In this embodiment, the abnormal power variance E can be less than or equal to 7.1.

[0090] Furthermore, the intelligent analysis module is further configured to re-determine whether to increase the signal transmission power of the engine power sensor based on a comparison result between the average digging distance and the preset average digging distance.

[0091] Specifically, in this embodiment, the intelligent analysis module can also obtain the location information of each mining equipment in the mine through the spatiotemporal data acquisition unit in the production scheduling module, so as to determine the excavation distance of each mining equipment; set a preset average excavation distance H0 = 300 meters. It should be noted that H0 can also be changed to other values according to changes in the location of the spatiotemporal data acquisition unit and the location of abnormal equipment; the comparison process based on the average excavation distance H and the preset average excavation distance is as follows:

[0092] If the average excavation distance H is less than or equal to the preset average excavation distance H0, it means that the current excavation distance of each abnormal equipment in the mine is relatively short. At this time, if it is determined that the construction of the production plan does not meet the standards, it can be determined that there is a problem with the abnormal equipment itself, and a maintenance notice can be issued for the abnormal equipment.

[0093] If the average excavation distance H is greater than the preset average excavation distance H0, it means that the current excavation distance of each abnormal equipment in the mine is relatively long. At this time, it can be determined that the reason why the construction of the production plan does not meet the standards is that the excavation distance is too long, resulting in problems in the data transmission process. It is determined that the signals emitted by each sensor have attenuated due to the long transmission distance. At this time, the collaborative control module can be adjusted through the adjustment module to increase the signal transmission power of each engine power sensor to suit long-distance data transmission. Among them, the initial setting of the signal transmission power of each engine power sensor is determined by the production plan.

[0094] Furthermore, the intelligent analysis module is also used to determine, based on a comparison result of the excavation distance difference with a preset excavation distance difference, to increase the signal transmission power of the engine power sensor, and the increase in the signal transmission power is positively correlated with the excavation distance difference; wherein the excavation distance difference is the difference between the average excavation distance and the preset average excavation distance.

[0095] Specifically, in this embodiment, it is clear that several sensors including but not limited to the engine power sensor can perform adaptive signal transmission power adjustment according to the excavation distance difference L. Taking the cutting part of the coal mining machine as an example to perform corresponding sensor signal transmission power adjustment, the preset excavation distance difference L0 can be divided into a first preset excavation distance difference L1 and a second preset excavation distance difference L2, and the preset excavation distance difference L3 is set to 50 meters, L1 = L3-20, and L2 = L3+20. The specific comparison process based on the excavation distance difference L with L1 and L2 is as follows:

[0096] In normal excavation operations, as the excavation distance increases, the engine power sensor signal also increases accordingly; if the excavation distance difference L is less than or equal to the first preset excavation distance difference L1 and can be greater than or equal to 10 meters, the first signal transmission power adjustment coefficient instruction is generated by the intelligent analysis module, and the adjustment module obtains the first signal transmission power adjustment coefficient instruction to increase the signal transmission power of the engine power sensor arranged on the abnormal equipment, which is 0.4 times higher than the initial value; if the excavation distance difference L is greater than the first preset excavation distance difference L1 and less than or equal to the second preset excavation distance difference L2, the intelligent analysis module generates a first signal transmission power adjustment coefficient instruction. The block generates a second signal transmission power adjustment coefficient instruction, and the adjustment module obtains the second signal transmission power adjustment coefficient instruction to increase the signal transmission power of the engine power sensor arranged on the abnormal device, increasing it by 0.5 times the initial value; if the excavation distance difference L is greater than the second preset excavation distance difference L2 and can be less than or equal to 100 meters, the intelligent analysis module generates a third signal transmission power adjustment coefficient instruction, and the adjustment module obtains the third signal transmission power adjustment coefficient instruction to increase the signal transmission power of the engine power sensor arranged on the abnormal device, increasing it by 0.6 times the initial value. In this embodiment, the increase adjustment factor of the signal transmission power can also be set to other values to ensure that the signal sent by the engine power sensor can be effectively received by the device data unit, and the sensor power fluctuation is usually limited to a safe threshold through circuit design to avoid heat and energy consumption problems.

[0097] Furthermore, the intelligent analysis module is also used to determine the increase of the filter window length based on the comparison result of the vibration velocity mean and the preset vibration velocity mean, and the increase amplitude of the filter window length is proportional to the vibration velocity mean; wherein, the collaborative control module also includes a number of vibration sensors arranged on the corresponding mining equipment, and the equipment data acquisition unit is connected to the number of vibration sensors and collects the vibration velocity at the corresponding position of the mining equipment, and the average value of the vibration velocity is calculated based on the number of vibration velocities to obtain the vibration velocity mean.

[0098] Specifically, in this embodiment, the vibration velocity information of the cutting part of a coal mining machine in a type of mining equipment is collected as an example; the preset vibration velocity mean K0 can be divided into a first preset vibration velocity mean K1 and a second preset vibration velocity mean K2, and the preset vibration velocity mean standard K3 is set to 9 mm / s, K1 = 0.9 × K3, and K2 = 1.1 × K3. It should be noted that K1, K2, and K3 can also be set to other values when changing according to relevant parameters. The setting of K3 conforms to the vibration velocity standard setting of the cutting part of the coal mining machine; the comparison process based on the vibration velocity mean K with K1 and K2 is as follows:

[0099] If the vibration velocity mean K is less than or equal to the first preset vibration velocity mean K1, a first filter window length adjustment coefficient instruction is generated by the intelligent analysis module, and the filter window length of the equipment data processing unit during the preprocessing process is increased and adjusted by the adjustment module, and the filter window length is increased to 1.2 times the initial value; if the vibration velocity mean K is greater than the first preset vibration velocity mean K1 and less than or equal to the second preset vibration velocity mean K2, a second filter window length adjustment coefficient instruction is generated by the intelligent analysis module, and the filter window length of the equipment data processing unit during the preprocessing process is increased and adjusted by the adjustment module, and the filter window length is increased to 1.25 times the initial value; if the vibration velocity mean K is greater than the second preset vibration velocity mean K2, a third filter window length adjustment coefficient instruction is generated by the intelligent analysis module, and the filter window length of the equipment data processing unit during the preprocessing process is increased and adjusted by the adjustment module, and the filter window length is increased to 1.3 times the initial value. In this embodiment, the cutting part of the coal mining machine works under normal working conditions, and the filter window length growth rate can also be set to other values, but the growth rate should be set within an appropriate range to meet the growth range requirements under the corresponding working conditions.
