[0010] 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.

[0011] Furthermore, the intelligent analysis module is also used to determine the reason why the construction of the production plan does not meet the standard based on the comparison result of the abnormal power variance and the preset abnormal power variance and generate corresponding instructions based on the reason, and determine the corresponding processing based on the instructions, including: re-determining the corresponding processing based on the comparison result of the average excavation distance and the preset average excavation distance, increasing the filter window length in the preprocessing process, or issuing a maintenance notice for the mining equipment; Among them, the intelligent analysis module is also used to record the 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 as an abnormal equipment, and to perform variance calculation based on the engine powers of several abnormal equipment to obtain the abnormal power variance; the average excavation distance is the average value of several excavation distances obtained by the spatiotemporal data acquisition unit when several mining equipment are mining in the mine.

[0012] Furthermore, the intelligent analysis module is also used to re-determine whether to increase the signal transmission power of the engine power sensor based on the comparison result between the average digging distance and the preset average digging distance.

[0013] Furthermore, the intelligent analysis module is also used to determine, based on the comparison result of the excavation distance difference and the preset excavation distance difference, to increase the signal transmission power of the engine power sensor, and the increase range of the signal transmission power is proportional to the excavation distance difference; The excavation distance difference is the difference between the average excavation distance and the preset average excavation distance.

[0027] 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 respectively connected to the spatiotemporal data acquisition unit and the spatiotemporal data storage construction unit, and the spatiotemporal data storage construction unit is connected to the production plan construction unit.

[0028] 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 sent 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 the geographic information of the mine and the distribution information of ore resources; 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.

[0029] Among them, the spatiotemporal data processing unit includes a data format automatic identification and conversion engine, through which the data format automatic identification and conversion engine converts the format of several data information acquired by the sensor and automatically converts 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 the spatiotemporal positioning of ores, equipment, etc. is provided in the subsequent production scheduling process, so as to facilitate the rapid acquisition of corresponding data information; wherein, the standardized data information includes several mine geographic information, ore resource distribution information and mining equipment location information.

[0030] Among them, the spatiotemporal data storage construction unit can classify some 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, so as to form a hierarchical data storage architecture, distribute and store some data information on different storage nodes, and perform data backup operations regularly to prevent some data information from being lost due to hardware failure, natural disasters or human operation. Among them, the topography, slope and aspect, geological structure and other 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 regions are determined through resource distribution information, and the location and quantity of some mining equipment in different regions of the mine are determined through equipment location information, and subsequent production plans can be constructed based on this.

[0031] 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.

[0032] In this embodiment, a multi-level index is further established based on the basic layer, resource layer and dynamic layer, such as establishing a spatial grid index on the basic layer, establishing a spatial and resource attribute index on the resource layer, and establishing a time and device ID index on the dynamic layer, so as to improve the efficiency of data retrieval, thereby building a production plan more efficiently. 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 geographical point location of the mining equipment in the mine in an indoor environment or in an area where the GPS signal is limited, so as to ensure the accurate acquisition of the location information of the mining equipment.

[0033] See also Figure 3As shown, it is a module 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: The equipment control unit is connected to the production plan building 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.

[0034] 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.

[0035] 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.

[0036] 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, so as to realize 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.

[0037] 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.

[0038] Among them, the equipment data processing unit includes a central data processing center, through which several engine powers can be obtained and then data preprocessing can be performed. The preprocessing process includes noise reduction processing on the acquired 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) as a type of mining equipment, the engine power is between 500 kilowatts and 600 kilowatts (including 600 kilowatts) as a type of mining equipment, and the engine power is between 600 kilowatts and 700 kilowatts (including 700 kilowatts) as a type of mining equipment. There are other mining equipment in the future, and so on. 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 type one mining equipment is set to 500 kilowatts, the preset engine power of type two mining equipment is set to 600 kilowatts, and the preset engine power of type three mining equipment is set to 700 kilowatts. The preset engine power is determined based on the production plan.

[0039] 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.

[0040] 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: S1: Acquire actual mine parameters and location information of several mining equipment in the mine through a production scheduling module, and construct a production plan based on actual environmental parameters and location information of the mining equipment, wherein the actual mine parameters include mine geographic information and ore resource distribution information.

[0041] S2: Generate and send a real-time control signal to the corresponding mining equipment through the collaborative control module, and periodically obtain the engine power of the mining equipment.

[0042] 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.

[0043] S4: Acquire 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.

[0044] S5: Acquire the instruction through the regulating module respectively connected to the intelligent analysis module, the production scheduling module and the coordinated control module and determine the preset engine power or issue a maintenance notice for the mining equipment based on the instruction.

[0045] See also Figure 5 As shown, it is a logical judgment diagram for judging whether the construction process of the production plan meets the standards based on the absolute value of power in this embodiment. The intelligent analysis module is also used to make a judgment based on the comparison result of the absolute value of power and the preset absolute value of power, or to draw a dust change curve based on the obtained dust concentration information and re-judge whether the construction of the production plan meets the standards based on the dust change curve; when it is determined that the construction of the production plan does not meet the standards, the intelligent analysis module determines the reason for non-compliance based on the difference between the absolute value of power and the preset absolute value of power; wherein, the absolute value of power is the absolute value of the difference between the average value of the engine power of several mining equipment and the preset engine power.

[0046] Specifically, in this embodiment, an analysis is performed with a rated power of 500 kilowatts for a type of mining equipment as an example, the engine power of each mining equipment in the same type of mining equipment is obtained, and then the power average value is calculated, and then the absolute value of the difference between the power average value and the preset engine power is 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, and the preset power absolute value standard F3=45 kilowatts, F1=F3-5, F2=F3+5 is set. It should be noted that F1, F2 and F3 can also be adjusted according to relevant parameters; the comparison process based on the power absolute value F with F1 and F2 is as follows: If the power absolute value F is less than or equal to the first preset power absolute value F1, it means that the current power absolute value is relatively small, which is the 10%‌ instantaneous power fluctuation allowed by the cutting part. Therefore, it can be determined that the engine power of each mining device in the same type of mining equipment is not much different from the preset engine power, that is, most mining equipment can work normally as expected in the production plan, so it is determined that the construction of the production plan meets the standards. The minimum value of the power absolute value F is greater than 0.

[0047] 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 corresponding mining equipment area, and based on the curve, it can be further determined whether the construction of the production plan meets the standards.

[0048] If the power absolute value F is greater than the second preset power absolute value F2, it means that the current power absolute value is relatively large, so it can be determined that the engine power of most mining equipment of the same type of mining equipment is greatly different from the preset engine power, that is, most mining equipment cannot work normally as expected in the production plan, so it is determined that the construction of the production plan does not meet the standards. It is clear that the power absolute value F is not an infinite value.

[0049] Furthermore, the intelligent analysis module is also used to determine whether to reduce the preset engine power based on the comparison result of the dust change slope average value and the preset dust change slope average value; wherein, the dust change slope average value is the average value of the curve slopes of several mining equipment at corresponding points on the dust change curve.

[0050] 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 for coal 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 1 000-3000mg / m³, in this embodiment, the dust concentration range of the area where a single mining equipment is located during machine mining in the mine can be set to ‌1000–1500mg / m³‌; the preset dust change slope average value V0 is set to 80, it should be noted that V0 can be calculated according to relevant parameters to obtain other values, without specific limitation, and the dust total 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: If the dust change slope average value V is less than or equal to the preset dust change slope average value V0, 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.

[0051] If the dust change slope average value V is greater than the preset dust change slope average value V0, 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 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 at this time because it is affected by the dust concentration. The excessive dust concentration causes deviations 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.

[0052] 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.

[0053] 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=1300mg / m³, N1=N3-100, N2=N3+100 can be set. It should be noted that N1, N2 and N3 can also be set to other values ​​according to actual conditions, and the setting of N3 is in line with the existing technical standards; the comparison process based on the dust concentration N with N1 and N2 is as follows: Take 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 1000mg / m³, 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, and reduces 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, and reduces 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 1500mg / m³, the intelligent analysis module generates a third preset power adjustment coefficient instruction, and the adjustment module obtains the third preset power adjustment coefficient instruction to adjust the preset engine power in the intelligent analysis module, and reduces the preset engine power to 0.85 times the initial value. In this embodiment, the reduction ratio of the preset engine power can also be set to other values, but the maximum reduction range is usually not more than 15%, with the goal of effectively reducing the dust concentration in the corresponding area without affecting the ore mining work.

[0054] See also Figure 6As shown, it is a logical decision diagram for determining the reasons and corrections for the process of constructing the production plan that does not meet the standards based on the abnormal power variance in this embodiment. The intelligent analysis module is also used to determine the reasons why the construction of the production plan does not meet the standards based on the comparison results of the abnormal power variance and the preset abnormal power variance and generate corresponding instructions based on the reasons, and determine the corresponding processing based on the instructions, including: re-determining the corresponding processing based on the comparison results of the average excavation distance and the preset average excavation distance, increasing the filter window length in the preprocessing process, or issuing a maintenance notice for the mining equipment; wherein, the intelligent analysis module is also used to record the 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 as an abnormal equipment, and to perform variance calculation based on the engine power of several abnormal equipment to obtain the abnormal power variance; the average excavation distance is the average value of several excavation distances obtained by the spatiotemporal data acquisition unit when several mining equipment are mining in the mine.

[0055] Specifically, in this embodiment, taking the cutting part of a coal mining machine in a type of mining equipment as an example, specifically, 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=6.9, E1=0.97×E3, E2=1.02×E3 is set. It should be noted that E1, E2 and E3 can also be set to other values ​​according to the changes in relevant parameters; the comparison process based on the abnormal power variance E with E1 and E2 is as follows: If the abnormal power variance E is less than or equal to the first preset abnormal power variance E1, it means that the absolute value of the difference between the current engine power of each abnormal device and the preset engine power is relatively close in value as a whole. At this time, the location information of each abnormal device in the mine can be obtained through the spatiotemporal data acquisition unit, and then the excavation distance of the abnormal device when mining in the corresponding area of ​​the mine can be obtained. The excavation distance here refers to the shortest straight-line distance between the abnormal device and the spatiotemporal data acquisition unit in space, and then the average value is calculated based on several excavation distances to obtain the average excavation distance, and the corresponding processing method is re-determined based on the comparison result of the average excavation distance and the preset average excavation distance. In this embodiment, the abnormal power variance E can be greater than or equal to 6.4.

[0056] 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 indicates that the absolute value of the difference between the engine power of each current abnormal device and the preset engine power is numerically between proximity and dispersion as a whole. At this time, it can be determined that there is a problem in the device data processing unit of the collaborative control module during the preprocessing of the engine power. Corresponding adjustments can be made to the preprocessing process. In this embodiment, the central data processing center in the device data processing unit uses a moving average filtering method to filter the data information. Specifically, the smoothing degree of the processed engine power can be improved by appropriately increasing the filtering window length during the noise reduction process, thereby reducing the abnormal conditions of the data. Among them, the initial setting of the filtering window length is determined by the production plan.

[0057] If the abnormal power variance E is greater than the second preset abnormal power variance E2, it indicates that the absolute value of the difference between the engine power of each current abnormal device and the preset engine power is relatively dispersed as a whole. It can be determined that there is a problem with the abnormal device itself. A preset critical value A = 10 kW is set. If the difference between the engine power in the abnormal device and the preset engine power is greater than A, a maintenance notice is issued for the abnormal device. In this embodiment, the abnormal power variance E can be less than or equal to 7.1.

[0058] Furthermore, the intelligent analysis module is also used to re - determine whether to increase the signal transmission power of the engine power sensor based on the comparison result between the average mining distance and the preset average mining distance.

[0059] Specifically, in this embodiment, the intelligent analysis module can also obtain the position information of each mining device in the mine through the spatio - temporal data acquisition unit in the production scheduling module, so as to determine the mining distance of each mining device; a preset average mining distance H0 = 300 m is set. It should be noted that H0 can also be changed to other values according to the changes in the positions of the spatio - temporal data acquisition unit and the abnormal device. The specific process of comparing the average mining distance H with the preset average mining distance is as follows: If the average mining distance H is less than or equal to the preset average mining distance H0, it indicates that the mining distance of each current abnormal device 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 device itself, and a maintenance notice for the abnormal device can be issued.

[0060] If the average excavation distance H is greater than the preset average excavation distance H0, it means that the current excavation distances of the various abnormal equipment in the mine are 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.

[0061] Furthermore, the intelligent analysis module is also used to determine whether to increase the signal transmission power of the engine power sensor based on the comparison result of the excavation distance difference and the preset excavation distance difference, and the increase in the signal transmission power is proportional to the excavation distance difference; wherein the excavation distance difference is the difference between the average excavation distance and the preset average excavation distance.

[0062] Specifically, in this embodiment, it can be clearly understood that a number of 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=50 meters, L1=L3-20, L2=L3+20 is set; the comparison process based on the excavation distance difference L with L1 and L2 is as follows: 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, 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. 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 in the engine power sensor arranged on the abnormal device, which is 0.5 times higher than 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 in the engine power sensor arranged on the abnormal device, which is 0.6 times higher than the initial value. In this embodiment, the increase adjustment ratio 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 heating and energy consumption problems.

[0063] 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 plurality of vibration sensors arranged on the corresponding mining equipment, and the equipment data acquisition unit is connected to the plurality of vibration sensors and collects the vibration velocity at the corresponding position of the mining equipment, and the vibration velocity mean is obtained by calculating the average value based on the plurality of vibration velocities.

[0064] Specifically, in this embodiment, the vibration velocity information of the cutting part of the 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=9mm / s is set, K1=0.9×K3, K2=1.1×K3, it should be noted that K1, K2 and K3 can also be set to other values ​​when the relevant parameters are changed, and 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: 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 through the intelligent analysis module, and the filter window length of the equipment data processing unit during the preprocessing process is increased and adjusted through 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 through the intelligent analysis module, and the filter window length of the equipment data processing unit during the preprocessing process is increased and adjusted through 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 through the intelligent analysis module, and the filter window length of the equipment data processing unit during the preprocessing process is increased and adjusted through 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.
