Abstract
Description
Technical Field
[0001] This invention relates to the field of coal mine hot air handling unit technology, and in particular to an energy-saving control system and method based on coal mine hot air handling unit. Background Technology
[0002] Coal mines, as important energy production bases, are themselves high-energy-consuming units. In frigid regions or during winter, coal mine hot air units (also known as mine heating units) play a crucial role in ensuring safe production and personnel comfort, providing insulation, frost protection, and preheating for ventilation at air intakes, underground work areas, and surface industrial areas. These devices typically have enormous power and long operating hours, and their energy consumption accounts for a significant proportion of the total energy consumption in the mining area, making them an important optimization link for enterprises to reduce costs, increase efficiency, and achieve "dual carbon" goals.
[0003] However, practice has shown that traditional hot air handling unit control mainly relies on the experience of operators for manual adjustment. In practice, operators usually set the operating parameters of the hot air handling unit manually based on historical experience, limited environmental perception (such as the temperature of individual points), and subjective judgment. Once the parameters are set, if the operators do not actively adjust the operating parameters, the hot air handling unit will often operate based on these manually set operating parameters for a long time. This results in the phenomenon that when the internal and external environment of the mine changes, and the actual temperature and humidity in some areas have reached or even exceeded the comfort requirements, the hot air handling unit continues to supply heat and air according to the original set operating parameters, i.e., overheating supply, which causes the hot air handling unit to operate continuously with high energy consumption.
[0004] Therefore, it is particularly important to propose a technical solution to improve the accuracy of energy-saving control of coal mine hot air units. Summary of the Invention

[0118] Based on the calculated usage requirement satisfaction value and security requirement satisfaction value of each partition, determine whether they are greater than or equal to their respective preset satisfaction thresholds.
[0119] When it is determined that the usage requirement satisfaction value and safety requirement satisfaction value of a preset number of partitions are greater than or equal to their respective preset satisfaction thresholds, the mine is determined to meet the preset priority requirement satisfaction condition.
[0120] In this embodiment of the invention, for the calculation of the degree of satisfaction of the usage requirements, the following can be selected as inputs: zone environmental parameters: such as working surface A temperature 23℃, humidity 60%; equipment status parameters: current air volume of fan in zone A 800m³ / h (target requires 1000m³ / h).
[0121] Calculation steps:
[0122] Environmental deviation: Calculates the deviation (e.g., +1℃) of the temperature from the preset target range (18-22℃).
[0123] Equipment compatibility: such as calculating the ratio of actual air volume to target air volume (800 / 1000=0.8).
[0124] Weighted synthesis: Combines environmental deviations and equipment matching degree according to weight (e.g., 7:3) into a satisfaction value.
[0125] Further optional, for the calculation of the safety requirement satisfaction value, the input can be: safety environment parameters: such as the gas concentration in roadway B is 0.6% (critical value 0.8%); safety equipment status: whether the standby fan is in normal standby status (yes=1, no=0).
[0126] Calculation steps:
[0127] Safety deviation: Calculate the ratio of the difference between the gas concentration and the critical value (e.g., (0.8-0.6) / 0.8=0.25).
[0128] Equipment compatibility: Check the availability of the backup fan (if normal, compatibility = 1).
[0129] Weighted aggregation: Combined into a satisfaction value according to safety weight.
[0130] Further optionally, for the global judgment logic, when the usage / security satisfaction value of ≥80% of the partition is ≥0.7 (preset threshold), energy-saving control is triggered.
[0131] Further optionally, the priority requirement satisfaction conditions include the usage requirement satisfaction conditions and / or safety requirement satisfaction conditions for each zone of the mine; in actual application, when it is necessary to choose one to use, the unused conditions can be 0 or empty when calculating the corresponding specific satisfaction value.
[0132] As can be seen, implementing this optional embodiment can improve the refinement of demand assessment and the targeting of zoned governance by independently calculating the demand satisfaction value and safety demand satisfaction value for each zone. This is conducive to accurately identifying the individual shortcomings of different zones, and in turn, to building a multi-dimensional dynamic profile of the overall mine operation status, thus upgrading from extensive management to precise zoned governance. By using a preset quantity threshold triggering mechanism, the interference intensity of local anomalies on energy-saving decisions is reduced, which helps to ensure the stability of the system under some fluctuating operating conditions. This, in turn, helps to maximize the capture of global energy-saving opportunities and achieve synergistic enhancement of resource utilization efficiency and system robustness.
[0133] In this optional embodiment, as an optional implementation method, the specific method by which the judgment module 102 calculates the usage demand satisfaction value of each zone of the mine based on the zoned environmental parameters in the first multi-dimensional environmental parameters and the zoned equipment status parameters in the multi-dimensional status parameters includes:
[0134] For each partition, calculate a first distance value between the partition environment parameters of that partition and the preset target range of the partition environment requirements for that partition. The first distance value is used to represent the degree of deviation between the partition environment parameters and the corresponding preset target range of the partition environment requirements.
[0135] Calculate the first matching degree value between the partition device state parameters of the partition and the theoretical device state parameters required to achieve the partition environment requirement target range of the partition. The first matching degree value is used to represent the degree of matching between the partition device state parameters and the corresponding theoretical device state parameters.
[0136] Based on all first distance values and all first matching degree values and their corresponding preset first priority values, calculate the usage requirement satisfaction value for each partition of the mine. The preset first priority value is associated with the attribute parameters of each partition.
[0137] In this embodiment of the invention, optionally, the calculation of the first distance value is as follows:
[0138] Target range deviation:
[0139] Example: The target temperature for zone C is 20±2℃, the actual temperature is 25℃, the deviation is 25-22=3℃ (exceeding the upper limit).
[0140] Normalization: The percentage of the deviation value relative to the target range width (e.g., if the target range is 4℃, then the deviation rate = 3 / 4 = 75%).
[0141] Further, optionally, the first matching degree value is calculated as follows:
[0142] Theoretical equipment status: Calculate the required fan power based on the thermodynamic model (e.g., 50kW fan power is required for the target temperature).
[0143] Actual matching degree: Actual power 45kW, matching degree = 45 / 50 = 0.9.
[0144] Further optional, for priority weighting:
[0145] Weighting: Set according to the importance of the zone (e.g., coal face weight 0.9, transport roadway weight 0.5).
[0146] Final satisfaction: Satisfaction = (1 - distance value) × distance weight + matching degree × matching weight (e.g., distance weight 0.6, matching weight 0.4, satisfaction = (1 - 0.75) × 0.6 + 0.9 × 0.4 = 0.57).
[0147] In this embodiment of the invention, optionally, the attribute parameters of the partition refer to the inherent, essential attributes of the partition that do not change with short-term operating conditions, used to define the basic characteristics and long-term requirements of the partition, including but not limited to:
[0148] Functional types: coal mining face, transport roadway, electromechanical chamber, refuge chamber, etc.
[0149] Function: To determine the environmental requirements of the zone (e.g., the coal face needs to be kept at a low temperature, and the electromechanical chamber needs to be moisture-proof).
[0150] Location topology: The spatial location of a zone within the mine (such as its depth from the main shaft opening and the connection relationship between adjacent zones).
[0151] Function: To influence the energy consumption coupling calculation of the hot air delivery path (e.g., higher air pressure is required for remote zones).
[0152] Safety risk level: gas emission level (high / medium / low), coal seam spontaneous combustion tendency level.
[0153] Function: Determines the stringency of safety thresholds (e.g., lower safety thresholds in high-gas areas).
[0154] Equipment configuration specifications: rated power, maximum air volume, and supported control modes (variable frequency / fixed frequency) of the hot air blower.
[0155] Function: To limit the range of adjustment of state parameters (e.g., small fans cannot be overclocked).
[0156] Example: A certain partition attribute: {Function type: "Coal mining face", Depth: "500m from the wellhead", Gas level: "Class III", Fan model: "FBD-6.3"}.
[0157] It is evident that implementing this optional embodiment can quantify the degree of environmental parameter deviation through the first distance value, improve the accuracy of the numerical representation of environmental demand deviation, thereby facilitating the dynamic positioning of high-deviation zones that require priority control, and further helping to eliminate response delays caused by experience-based decision-making, thus achieving an objective assessment of the mine's environmental demand satisfaction. By associating equipment status with theoretical requirements through the first matching degree value, the risk of disconnect between equipment operating capacity and target requirements is reduced, thereby helping to identify hidden bottlenecks of equipment resource redundancy or insufficiency, and further helping to optimize the load balancing strategy of equipment clusters, achieving a precise improvement in the operating efficiency of hot air units. By dynamically weighting the calculation through a preset first priority value, the decision weight of core zones is increased, thereby facilitating the implementation of differentiated guarantee strategies under resource constraints, and further helping to focus on the environmental stability of key areas, achieving strategic support for mine production efficiency.
[0158] In this optional embodiment, as another optional implementation, the specific method by which the judgment module 102 calculates the safety requirement satisfaction value of each zone of the mine based on the safety environment parameters in the first multi-dimensional environmental parameters and the safety equipment status parameters in the multi-dimensional status parameters includes:
[0159] For each partition, a second distance value is calculated between the security environment parameters of that partition and the preset security threshold value of that partition. The second distance value is used to represent the degree of deviation of the security environment parameters from the corresponding security threshold value. The security threshold value is used to define the preset security boundary of the key security indicators of that partition.
[0160] Calculate the second matching degree value between the safety equipment status parameters and the safety equipment baseline status parameters of the partition. The safety equipment baseline status parameters are used to characterize the minimum equipment operation requirements to meet the preset safety requirements. The second matching degree value is used to indicate the degree of matching between the safety equipment status parameters and the safety equipment baseline status parameters.
[0161] Based on all second distance values and all second matching degree values and their corresponding preset second priority values, calculate the safety requirement satisfaction value for each zone of the mine; the preset second priority value is associated with the current work items of each zone.
[0162] In this embodiment of the invention, optionally, the calculation of the second distance value is as follows:
[0163] Safety boundary deviation:
[0164] Example: The critical gas value for zone D is 0.8%, the actual value is 0.9%, and the deviation is (0.9-0.8) / 0.8=12.5%.
[0165] Negative value handling: If the actual measured value is 0.7%, the deviation value is negative (safety redundancy).
[0166] Further, optionally, the second matching degree value is calculated as follows:
[0167] Baseline status parameters: Minimum requirements for safety equipment (e.g., two redundant wind turbines must be online).
[0168] Matching score: 1 device is actually online, matching score = 0.5.
[0169] Further optional, regarding job association priority:
[0170] Dynamic weight: If a blasting operation is underway in a zone, the safety weight is increased from 0.6 to 0.9.
[0171] Satisfaction calculation: Satisfaction = (1 - Deviation value) × Deviation weight + Matching degree × Matching weight (Example: Deviation weight 0.7, Satisfaction = (1 - 0.125) × 0.7 + 0.5 × 0.3 = 0.76).
[0172] Optionally, work items refer to temporary production or safety activities currently underway in a zone, used to dynamically adjust the priority of safety requirements, including but not limited to:
[0173] Production activities include blasting operations, coal transportation, equipment installation, and tunnel excavation.
[0174] Purpose: The dust concentration threshold needs to be more stringent during tunneling operations.
[0175] Safety incident status: Gas over-limit warning, fire risk monitoring, equipment malfunction alarm.
[0176] Function: When a gas warning is issued, the safety priority is automatically raised to the highest level.
[0177] Maintenance tasks: Equipment overhaul and ventilation system calibration.
[0178] Purpose: To allow for temporary relaxation of environmental parameter requirements during maintenance.
[0179] Example: Current task: {Activity type: "Blasting operation", Safety event: "None", Maintenance status: "Wind turbine A under maintenance"}.
[0180] It is evident that implementing this optional embodiment can quantify the critical state of safety margin through the second distance value, improving the sensitivity and operability of safety risk early warning. This facilitates proactive defense and control at the safety boundary, thereby helping to break the chain of accident escalation and achieving proactive intervention capabilities in safety management. By verifying the readiness of safety equipment through the second matching degree value, the potential for emergency response failure is reduced, which helps to ensure the real-time availability of the safety protection system and improve the overall fault tolerance of the system, achieving dynamic reinforcement of safety redundancy. By dynamically adjusting the second priority value associated with operations, the intensity of safety resource allocation in high-risk scenarios is increased, which helps to match the intensity of mine operations with the real-time safety requirements of mine operations, thereby avoiding resource mismatch caused by fixed strategies and achieving scenario-adaptive optimization of safety protection.
[0181] The control module 103 is used to generate dynamic energy-saving control instructions for the coal mine hot air unit based on the priority demand satisfaction condition and the newly acquired second multi-dimensional environmental parameters of the mine when the judgment module 102 determines that the mine meets the priority demand satisfaction condition, so as to regulate the multi-dimensional state parameters.
[0182] In this embodiment of the invention, optionally, the second multi-dimensional environmental parameter is used to generate a dynamic energy-saving control command in combination with the priority demand satisfaction condition. The second multi-dimensional environmental parameter can correspond to the first multi-dimensional environmental parameter.
[0183] Further optional, in terms of time sequence, the first multi-dimensional environmental parameter can be the "snapshot" data initially acquired by the system for quick decision-making; the second multi-dimensional environmental parameter can be the updated data acquired later, or even more detailed real-time data, to reflect the dynamic changes in the current mine environment, or even predict the dynamic changes in the mine environment within a preset time period, for fine control.
[0184] In this embodiment of the invention, optionally, the above-mentioned dynamic energy-saving command generation is as follows:
[0185] Input: Target value in the priority conditions (such as temperature range), real-time environmental data (such as current working surface temperature 25℃).
[0186] Output: The PID algorithm calculates that the fan speed needs to be reduced by 10%, and the air valves in non-core areas need to be closed to reduce total power consumption while maintaining environmental compliance in critical areas.
[0187] It is evident that implementing the embodiments of the present invention can improve the comprehensiveness and real-time performance of data acquisition by obtaining the first multi-dimensional environmental parameters of the mine and the corresponding multi-dimensional state parameters of the coal mine hot air blower unit. This enhances the accuracy, comprehensiveness, and timeliness of the perception of the overall mine operation status, breaks through the limitations of traditional single-point control, and improves the reliability of the system's decision-making basis. By establishing a judgment mechanism for the mine's priority demand satisfaction conditions, from the three dimensions of perception of the mine's overall operation status, satisfaction conditions of usage demands, and satisfaction conditions of safety demands, it improves the accuracy and comprehensiveness of the analysis and judgment of triggering the system's energy-saving control and the accuracy of energy-saving control of the coal mine hot air blower unit, ensuring that safety and usage demands always take precedence over energy saving. The goal is to achieve a unified multi-dimensional analysis and control of coal mine hot air blower units, encompassing energy conservation, safety assurance, and demand supply. When the judgment result is positive, dynamic energy-saving control commands are generated based on priority demand satisfaction conditions and newly acquired second-dimensional environmental parameters of the mine. This improves the adaptability, flexibility, accuracy, and comprehensiveness of the control scenarios for coal mine hot air blower units, facilitating real-time matching with dynamic changes in the mine environment. This helps avoid ineffective or excessive energy supply, enabling refined and flexible on-demand allocation of energy consumption around the clock. Ultimately, this improves coal mine production efficiency, ensures safe production, enhances energy consumption management capabilities, and contributes to the realization of smart and green mines.
[0188] In this embodiment of the invention, as another optional implementation, the control module 103 generates dynamic energy-saving control instructions for the coal mine hot air unit based on the priority demand satisfaction condition and the newly acquired second multi-dimensional environmental parameters of the mine. The specific methods for regulating the multi-dimensional state parameters include:
[0189] Extract the usage requirement satisfaction value and safety requirement satisfaction value of each zone of the mine from the priority requirement satisfaction condition, as well as their corresponding preset first priority value and preset second priority value;
[0190] Based on the extracted usage demand satisfaction value, safety demand satisfaction value, preset first priority value, preset second priority value, and newly acquired second multi-dimensional environmental parameters of the mine, the target state parameters to be regulated for each zone of the mine are determined respectively; the target state parameters are used to characterize the operating state of the corresponding hot air blower equipment in the zone that is required to achieve energy saving under the condition of satisfying the priority demand satisfaction of the corresponding zone.
[0191] Based on the target state parameters determined by all zones and their corresponding preset first priority value and preset second priority value, a collaborative control strategy for coal mine hot air blower units is generated; the collaborative control strategy is used to coordinate the resource allocation and operating parameter settings of hot air blower equipment in different zones.
[0192] Based on the coordinated control strategy, dynamic energy-saving control commands for coal mine hot air units are generated to regulate multi-dimensional state parameters.
[0193] In this embodiment of the invention, optionally, the target state parameters are determined as follows:
[0194] Input Extraction:
[0195] Zoning priority: Coal face usage weight 0.8, safety weight 0.9; Roadway usage weight 0.4.
[0196] Real-time environment: For example, the temperature in partition E rises to 26°C (exceeding the target of 22°C).
[0197] Calculation objective:
[0198] Allocate resources according to priority: increase the power of coal face ventilation fans to 110%, and reduce the power of roadways to 70%.
[0199] Target parameter: Increase the speed of fan A from 1000 rpm to 1200 rpm.
[0200] Further, alternatively, for coordinated regulation strategies:
[0201] Resource coordination:
[0202] Conflict identified: Total power capacity 1000kW, current demand 1200kW.
[0203] Dynamic adjustment: Reduce the quota of low-weight zones according to priority (e.g., close the air valves in non-operational areas).
[0204] Instruction generation:
[0205] Output JSON command package: {Fan A: Speed +20%, Valve B: Close}.
[0206] It is evident that implementing this optional embodiment can improve the customization level and scenario fit of energy-saving strategies by independently calculating target state parameters for each partition. This facilitates accurate matching of the actual operating conditions of each partition, thereby eliminating local energy waste caused by "one-size-fits-all" control and enabling in-depth exploration of energy-saving potential. Through multi-partition collaborative control strategies, resource contention between devices is reduced, which helps promote cross-partition energy consumption complementarity and linkage optimization. This, in turn, helps to leverage the system's cascade energy-saving effect and achieve a systematic reduction in overall energy consumption and global optimization of resource utilization.
[0207] In this optional embodiment, as an optional implementation method, the control module 103 determines the specific method by which it determines the target state parameters to be regulated for each zone of the mine based on the extracted usage requirement satisfaction value, safety requirement satisfaction value, preset first priority value, preset second priority value, and newly acquired second multi-dimensional environmental parameters of the mine.
[0208] For each partition, based on the partition's usage demand satisfaction value and the preset first priority value, the first dynamic adjustment coefficient of the partition's usage dimension is calculated. The first dynamic adjustment coefficient is used to represent the intensity of state parameter adjustment required based on the current usage demand satisfaction and its importance level.
[0209] Based on the security requirement satisfaction value and the preset second priority value of the partition, the second dynamic adjustment coefficient of the security dimension of the partition is calculated. The second dynamic adjustment coefficient is used to represent the intensity of state parameter adjustment required based on the current security requirement satisfaction and its urgency level.
[0210] Based on the current environmental parameters in the newly acquired second multi-dimensional environmental parameters of the mine and the preset environmental parameter benchmark values for the partition, the environmental state offset of the partition is determined; the current environmental parameters are used to represent the latest environmental status of the corresponding partition; the environmental parameter benchmark values are used to characterize the reference environmental level of the partition under preset typical working conditions;
[0211] Based on the first dynamic adjustment coefficient, the second dynamic adjustment coefficient, the environmental state offset, and the rated operating parameters of the hot air blower equipment in the zone, the preliminary target state parameters that need to be regulated in the zone are calculated; the rated operating parameters are used to define the standard operating capacity range of the hot air blower equipment in the zone.
[0212] Based on the topological relationships between the zones of the mine and the coupling characteristics of equipment operation, the energy consumption coupling influence factor of the zone relative to other zones is determined; the energy consumption coupling influence factor is used to quantify the degree of indirect impact of the zone's state parameter adjustment on the overall system energy consumption.
[0213] Based on the initial target state parameters and energy consumption coupling influence factors, the final target state parameters required for regulation in this partition are obtained by correction.
[0214] In this embodiment of the invention, optionally, the current environmental parameters in the newly acquired second multi-dimensional environmental parameters of the mine correspond to the aforementioned partitioned environmental parameters.
[0215] Further optional, for the calculation of dynamic adjustment coefficients:
[0216] Using dimensionality coefficients:
[0217] If a satisfaction level of 0.6 is used (below the threshold of 0.7), and a weight of 0.8 is applied, the adjustment coefficient = (1-0.6)×0.8=0.32 (requiring stronger regulation).
[0218] Security Dimension Coefficient:
[0219] If the safety satisfaction level is 0.9 (meets the standard), the weight is 0.9, and the adjustment coefficient is (1-0.9)×0.9=0.09 (weak regulation).
[0220] Further optional, for environmental offset correction:
[0221] Parameter association:
[0222] Example: Humidity in zone F is increased to 80% (baseline value 60%), offset = +20%.
[0223] Revised target: Dehumidification power needs to be increased, and the target value for fan power is increased by 15%.
[0224] Further optional, for coupling influence factors:
[0225] Topological association:
[0226] If the fan speed in zone G decreases, resulting in insufficient air pressure in the adjacent zone H, the coupling factor is 0.3 (moderate impact).
[0227] Final goal revised:
[0228] Initial target: speed reduction of 10%, but due to coupling effects, the actual speed reduction was corrected to 7%.
[0229] It is evident that implementing this optional embodiment can improve the intelligent adaptability of the control intensity by dynamically adjusting the coefficients associated with the urgency level of the demand, thereby facilitating rapid resource allocation response to urgent needs and avoiding inefficient averaging, thus achieving hierarchical agility in resource scheduling. By quantifying the regional correlation characteristics through energy consumption coupling influencing factors, the risk of systemic fluctuations caused by local adjustments is reduced, which helps to predict and offset cross-regional energy consumption chain reactions, thereby maintaining the overall operational stability of the hot air unit and achieving global collaborative optimization of energy-saving control and proactive offsetting of energy consumption fluctuations.
[0230] In this optional embodiment, as another optional implementation, the control module 103 generates a coordinated control strategy for the coal mine hot air unit based on the target state parameters determined by all partitions and their corresponding preset first priority values and preset second priority values in the following specific ways:
[0231] Determine the total dispatchable resources and operational constraints of the coal mine hot air unit; the operational constraints include the equipment safety threshold of the hot air unit and the preset minimum resource guarantee for each zone;
[0232] Identify the resource difference between the resource requirement corresponding to the target state parameters of each partition and the total schedulable resources;
[0233] Based on the preset first priority value, preset second priority value and resource difference of each partition, the target status parameters of each partition are dynamically adjusted.
[0234] Based on the adjusted target state parameters, a coordinated control strategy for coal mine hot air units is generated.
[0235] Optionally, resource constraint processing is performed in this embodiment of the invention as follows:
[0236] Dispatchable resources: Total power supply 800kW, equipment safety limit: Single fan power ≤200kW.
[0237] Minimum guarantee: At least 50kW must be allocated to each partition.
[0238] Further optional adjustments to resource discrepancies:
[0239] Demand identification:
[0240] Zone A has a demand of 180kW (priority 0.9), Zone B has a demand of 150kW (priority 0.5), and the total demand is 330kW, which is greater than the available capacity of 300kW.
[0241] Dynamic reallocation:
[0242] Area A will be fully satisfied according to priority (180kW), and the allocation for Area B will be 150×(300-180) / 150=120kW.
[0243] Further optional, for policy generation:
[0244] Output instructions:
[0245] Power curtailment mode: B zone fan power reduced to 80%, C zone non-core air valves closed to release 50kW.
[0246] It is evident that implementing this optional embodiment can improve the flexible decision-making capability in resource-constrained scenarios by dynamically adjusting the target parameters driven by resource differences. This is conducive to ensuring the basic supply of key zones according to priority, thereby avoiding operational crashes caused by system overload and achieving optimal trade-off control under limited resources. Through the priority-oriented resource reallocation mechanism, the proportion of ineffective energy consumption in low-value areas is reduced, which is conducive to focusing the energy supply intensity of high-priority zones, thereby maximizing the production efficiency output per unit of energy consumption, and realizing the strategic value focus of energy allocation and precise empowerment of energy efficiency transformation.
[0247] Example 2
[0248] Please see Figure 2 , Figure 2 This is a schematic flowchart of another energy-saving control method based on a coal mine hot air unit disclosed in an embodiment of the present invention. Figure 2 The described energy-saving control method based on coal mine hot air units can be applied to coal mine hot air units, and also to intelligent devices associated with coal mine hot air units. These intelligent devices include, but are not limited to, one or more of the following: switching equipment, cloud equipment, edge computing equipment, relay equipment, base station equipment, urban management equipment, and intelligent connected equipment. This invention does not limit the scope of these applications. Figure 2 As shown, the energy-saving control method based on coal mine hot air units may include the following operations:
[0249] 201. Obtain the first multi-dimensional environmental parameters of the mine and the corresponding multi-dimensional state parameters of the coal mine hot air unit;
[0250] 202. Based on the first multi-dimensional environmental parameters and multi-dimensional state parameters, determine whether the mine meets the preset priority demand satisfaction conditions. The priority demand satisfaction conditions include the usage demand satisfaction conditions and / or safety demand satisfaction conditions for each zone of the mine.
[0251] 203. When it is determined that the mine meets the priority demand satisfaction condition, dynamic energy-saving control instructions for the coal mine hot air unit are generated based on the priority demand satisfaction condition and the newly acquired second multi-dimensional environmental parameters of the mine, so as to regulate the multi-dimensional state parameters.
[0252] It is evident that implementing the embodiments of the present invention can improve the comprehensiveness and real-time performance of data acquisition by obtaining the first multi-dimensional environmental parameters of the mine and the corresponding multi-dimensional state parameters of the coal mine hot air blower unit. This enhances the accuracy, comprehensiveness, and timeliness of the perception of the overall mine operation status, breaks through the limitations of traditional single-point control, and improves the reliability of the system's decision-making basis. By establishing a judgment mechanism for the mine's priority demand satisfaction conditions, from the three dimensions of perception of the mine's overall operation status, satisfaction conditions of usage demands, and satisfaction conditions of safety demands, it improves the accuracy and comprehensiveness of the analysis and judgment of triggering the system's energy-saving control and the accuracy of energy-saving control of the coal mine hot air blower unit, ensuring that safety and usage demands always take precedence over energy saving. The goal is to achieve a unified multi-dimensional analysis and control of coal mine hot air blower units, encompassing energy conservation, safety assurance, and demand supply. When the judgment result is positive, dynamic energy-saving control commands are generated based on priority demand satisfaction conditions and newly acquired second-dimensional environmental parameters of the mine. This improves the adaptability, flexibility, accuracy, and comprehensiveness of the control scenarios for coal mine hot air blower units, facilitating real-time matching with dynamic changes in the mine environment. This helps avoid ineffective or excessive energy supply, enabling refined and flexible on-demand allocation of energy consumption around the clock. Ultimately, this improves coal mine production efficiency, ensures safe production, enhances energy consumption management capabilities, and contributes to the realization of smart and green mines.
[0253] In this embodiment of the invention, as an optional implementation, the aforementioned coal mine hot air unit includes hot air blower equipment corresponding to each zone. Based on first multi-dimensional environmental parameters and multi-dimensional state parameters, it determines whether the mine meets preset priority demand satisfaction conditions, including:
[0254] Based on the partition environment parameters in the first multi-dimensional environmental parameters and the partition equipment status parameters in the multi-dimensional status parameters, the usage demand satisfaction value of each partition of the mine is calculated respectively; the partition environment parameters are used to represent the environmental conditions of the partition; the partition equipment status parameters are used to represent the operating status of the hot air blower equipment serving the partition;
[0255] Based on the safety environment parameters in the first multi-dimensional environmental parameters and the safety equipment status parameters in the multi-dimensional status parameters, the safety requirement satisfaction value of each zone of the mine is calculated respectively; the safety environment parameters are used to represent the preset key environmental indicators that affect the operational safety level of the mine; the safety equipment status parameters are used to represent the operational status indicators of safety-related hot air blower equipment.
[0256] Based on the calculated usage requirement satisfaction value and security requirement satisfaction value of each partition, determine whether they are greater than or equal to their respective preset satisfaction thresholds.
[0257] When it is determined that the usage requirement satisfaction value and safety requirement satisfaction value of a preset number of partitions are greater than or equal to their respective preset satisfaction thresholds, the mine is determined to meet the preset priority requirement satisfaction condition.
[0258] As can be seen, implementing this optional embodiment can improve the refinement of demand assessment and the targeting of zoned governance by independently calculating the demand satisfaction value and safety demand satisfaction value for each zone. This is conducive to accurately identifying the individual shortcomings of different zones, and in turn, to building a multi-dimensional dynamic profile of the overall mine operation status, thus upgrading from extensive management to precise zoned governance. By using a preset quantity threshold triggering mechanism, the interference intensity of local anomalies on energy-saving decisions is reduced, which helps to ensure the stability of the system under some fluctuating operating conditions. This, in turn, helps to maximize the capture of global energy-saving opportunities and achieve synergistic enhancement of resource utilization efficiency and system robustness.
[0259] In this optional embodiment, as an optional implementation method, the above-mentioned calculation of the usage demand satisfaction value of each zone of the mine based on the zoned environmental parameters in the first multi-dimensional environmental parameters and the zoned equipment state parameters in the multi-dimensional state parameters includes:
[0260] For each partition, calculate a first distance value between the partition environment parameters of that partition and the preset target range of the partition environment requirements for that partition. The first distance value is used to represent the degree of deviation between the partition environment parameters and the corresponding preset target range of the partition environment requirements.
[0261] Calculate the first matching degree value between the partition device state parameters of the partition and the theoretical device state parameters required to achieve the partition environment requirement target range of the partition. The first matching degree value is used to represent the degree of matching between the partition device state parameters and the corresponding theoretical device state parameters.
[0262] Based on all first distance values and all first matching degree values and their corresponding preset first priority values, calculate the usage requirement satisfaction value for each partition of the mine. The preset first priority value is associated with the attribute parameters of each partition.
[0263] It is evident that implementing this optional embodiment can quantify the degree of environmental parameter deviation through the first distance value, improve the accuracy of the numerical representation of environmental demand deviation, thereby facilitating the dynamic positioning of high-deviation zones that require priority control, and further helping to eliminate response delays caused by experience-based decision-making, thus achieving an objective assessment of the mine's environmental demand satisfaction. By associating equipment status with theoretical requirements through the first matching degree value, the risk of disconnect between equipment operating capacity and target requirements is reduced, thereby helping to identify hidden bottlenecks of equipment resource redundancy or insufficiency, and further helping to optimize the load balancing strategy of equipment clusters, achieving a precise improvement in the operating efficiency of hot air units. By dynamically weighting the calculation through a preset first priority value, the decision weight of core zones is increased, thereby facilitating the implementation of differentiated guarantee strategies under resource constraints, and further helping to focus on the environmental stability of key areas, achieving strategic support for mine production efficiency.
[0264] In this optional embodiment, as another optional implementation, the above-mentioned calculation of the safety requirement satisfaction value of each zone of the mine based on the safety environment parameters in the first multi-dimensional environmental parameters and the safety equipment status parameters in the multi-dimensional status parameters includes:
[0265] For each partition, a second distance value is calculated between the security environment parameters of that partition and the preset security threshold value of that partition. The second distance value is used to represent the degree of deviation of the security environment parameters from the corresponding security threshold value. The security threshold value is used to define the preset security boundary of the key security indicators of that partition.
[0266] Calculate the second matching degree value between the safety equipment status parameters and the safety equipment baseline status parameters of the partition. The safety equipment baseline status parameters are used to characterize the minimum equipment operation requirements to meet the preset safety requirements. The second matching degree value is used to indicate the degree of matching between the safety equipment status parameters and the safety equipment baseline status parameters.
[0267] Based on all second distance values and all second matching degree values and their corresponding preset second priority values, calculate the safety requirement satisfaction value for each zone of the mine; the preset second priority value is associated with the current work items of each zone.
[0268] It is evident that implementing this optional embodiment can quantify the critical state of safety margin through the second distance value, improving the sensitivity and operability of safety risk early warning. This facilitates proactive defense and control at the safety boundary, thereby helping to break the chain of accident escalation and achieving proactive intervention capabilities in safety management. By verifying the readiness of safety equipment through the second matching degree value, the potential for emergency response failure is reduced, which helps to ensure the real-time availability of the safety protection system and improve the overall fault tolerance of the system, achieving dynamic reinforcement of safety redundancy. By dynamically adjusting the second priority value associated with operations, the intensity of safety resource allocation in high-risk scenarios is increased, which helps to match the intensity of mine operations with the real-time safety requirements of mine operations, thereby avoiding resource mismatch caused by fixed strategies and achieving scenario-adaptive optimization of safety protection.
[0269] In this embodiment of the invention, as another optional implementation, the above-mentioned generation of dynamic energy-saving control instructions for the coal mine hot air unit based on the priority demand satisfaction condition and the newly acquired second multi-dimensional environmental parameters of the mine, to regulate the multi-dimensional state parameters, includes:
[0270] Extract the usage requirement satisfaction value and safety requirement satisfaction value of each zone of the mine from the priority requirement satisfaction condition, as well as their corresponding preset first priority value and preset second priority value;
[0271] Based on the extracted usage demand satisfaction value, safety demand satisfaction value, preset first priority value, preset second priority value, and newly acquired second multi-dimensional environmental parameters of the mine, the target state parameters to be regulated for each zone of the mine are determined respectively; the target state parameters are used to characterize the operating state of the corresponding hot air blower equipment in the zone that is required to achieve energy saving under the condition of satisfying the priority demand satisfaction of the corresponding zone.
[0272] Based on the target state parameters determined by all zones and their corresponding preset first priority value and preset second priority value, a collaborative control strategy for coal mine hot air blower units is generated; the collaborative control strategy is used to coordinate the resource allocation and operating parameter settings of hot air blower equipment in different zones.
[0273] Based on the coordinated control strategy, dynamic energy-saving control commands for coal mine hot air units are generated to regulate multi-dimensional state parameters.
[0274] It is evident that implementing this optional embodiment can improve the customization level and scenario fit of energy-saving strategies by independently calculating target state parameters for each partition. This facilitates accurate matching of the actual operating conditions of each partition, thereby eliminating local energy waste caused by "one-size-fits-all" control and enabling in-depth exploration of energy-saving potential. Through multi-partition collaborative control strategies, resource contention between devices is reduced, which helps promote cross-partition energy consumption complementarity and linkage optimization. This, in turn, helps to leverage the system's cascade energy-saving effect and achieve a systematic reduction in overall energy consumption and global optimization of resource utilization.
[0275] In this optional embodiment, as an optional implementation method, the above-mentioned target state parameters to be regulated for each zone of the mine are determined based on the extracted usage requirement satisfaction value, safety requirement satisfaction value, preset first priority value, preset second priority value, and newly acquired second multi-dimensional environmental parameters of the mine, including:
[0276] For each partition, based on the partition's usage demand satisfaction value and the preset first priority value, the first dynamic adjustment coefficient of the partition's usage dimension is calculated. The first dynamic adjustment coefficient is used to represent the intensity of state parameter adjustment required based on the current usage demand satisfaction and its importance level.
[0277] Based on the security requirement satisfaction value and the preset second priority value of the partition, the second dynamic adjustment coefficient of the security dimension of the partition is calculated. The second dynamic adjustment coefficient is used to represent the intensity of state parameter adjustment required based on the current security requirement satisfaction and its urgency level.
[0278] Based on the current environmental parameters in the newly acquired second multi-dimensional environmental parameters of the mine and the preset environmental parameter benchmark values for the partition, the environmental state offset of the partition is determined; the current environmental parameters are used to represent the latest environmental status of the corresponding partition; the environmental parameter benchmark values are used to characterize the reference environmental level of the partition under preset typical working conditions;
[0279] Based on the first dynamic adjustment coefficient, the second dynamic adjustment coefficient, the environmental state offset, and the rated operating parameters of the hot air blower equipment in the zone, the preliminary target state parameters that need to be regulated in the zone are calculated; the rated operating parameters are used to define the standard operating capacity range of the hot air blower equipment in the zone.
[0280] Based on the topological relationships between the zones of the mine and the coupling characteristics of equipment operation, the energy consumption coupling influence factor of the zone relative to other zones is determined; the energy consumption coupling influence factor is used to quantify the degree of indirect impact of the zone's state parameter adjustment on the overall system energy consumption.
[0281] Based on the initial target state parameters and energy consumption coupling influence factors, the final target state parameters required for regulation in this partition are obtained by correction.
[0282] It is evident that implementing this optional embodiment can improve the intelligent adaptability of the control intensity by dynamically adjusting the coefficients associated with the urgency level of the demand, thereby facilitating rapid resource allocation response to urgent needs and avoiding inefficient averaging, thus achieving hierarchical agility in resource scheduling. By quantifying the regional correlation characteristics through energy consumption coupling influencing factors, the risk of systemic fluctuations caused by local adjustments is reduced, which helps to predict and offset cross-regional energy consumption chain reactions, thereby maintaining the overall operational stability of the hot air unit and achieving global collaborative optimization of energy-saving control and proactive offsetting of energy consumption fluctuations.
[0283] In this optional embodiment, as another optional implementation, the above-mentioned generation of a coordinated control strategy for coal mine hot air units based on the target state parameters determined by all partitions and their corresponding preset first priority values and preset second priority values includes:
[0284] Determine the total dispatchable resources and operational constraints of the coal mine hot air unit; the operational constraints include the equipment safety threshold of the hot air unit and the preset minimum resource guarantee for each zone;
[0285] Identify the resource difference between the resource requirement corresponding to the target state parameters of each partition and the total schedulable resources;
[0286] Based on the preset first priority value, preset second priority value and resource difference of each partition, the target status parameters of each partition are dynamically adjusted.
[0287] Based on the adjusted target state parameters, a coordinated control strategy for coal mine hot air units is generated.
[0288] It is evident that implementing this optional embodiment can improve the flexible decision-making capability in resource-constrained scenarios by dynamically adjusting the target parameters driven by resource differences. This is conducive to ensuring the basic supply of key zones according to priority, thereby avoiding operational crashes caused by system overload and achieving optimal trade-off control under limited resources. Through the priority-oriented resource reallocation mechanism, the proportion of ineffective energy consumption in low-value areas is reduced, which is conducive to focusing the energy supply intensity of high-priority zones, thereby maximizing the production efficiency output per unit of energy consumption, and realizing the strategic value focus of energy allocation and precise empowerment of energy efficiency transformation.
