This unit comprises multiple air compressors, each with constant parameter settings. However, this approach has limitations in understanding the overall gas consumption characteristics of the plant, and the air compressor units within the operating unit generally suffer from low operating efficiency. Furthermore, in practical applications, it is usually necessary to predict the overall plant's flow demand to determine whether to start and stop the air compressors within the operating unit, and consequently, the number of compressors. This can lead to excessive start-ups and shutdowns, affecting the lifespan of the air compressors and increasing maintenance costs.

[0053] To more clearly illustrate the embodiments of this application, the accompanying drawings used in the embodiments will be briefly introduced below. Obviously, the drawings described below are only some embodiments of this application. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0056] Figure 3 This is a schematic diagram of an air compressor operation setup device provided in an embodiment of this application. Detailed Implementation

[0057] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this application.

[0058] The core of this application is to provide an air compressor operation setting method, device, equipment and medium, so as to more rationally set the air compressor equipment operation combination, realize the balance of compressed air supply and demand, and improve the operating efficiency and service life of the air compressor.

[0059] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0060] With the rapid development of industry, compressed air is increasingly used in manufacturing. Air compressors produce compressed air; the rationality of their recommended operating combinations directly impacts energy efficiency and system operational safety. Typically, the on / off states and parameters of the air compression system at different times can be optimized and set to match the air output of the air compressor operating combinations with the factory's air consumption, thereby reducing the number of units required to operate and minimizing energy consumption. Therefore, how to rationally design the combination of units in an air compression system has always been a key research focus for technical personnel.

[0061] Currently, in factory production, air supply is typically provided around the clock using a single air compressor operating unit. This unit comprises multiple air compressors, each with constant parameter settings. However, this approach has limitations in understanding the overall gas consumption characteristics of the plant, and the air compressor units within the operating unit generally suffer from low operating efficiency. Furthermore, in practical applications, it is usually necessary to predict the overall plant's flow demand to determine whether to start and stop the air compressors within the operating unit, and consequently, the number of compressors. This can lead to excessive start-ups and shutdowns, affecting the lifespan of the air compressors and increasing maintenance costs.

[0062] Therefore, in order to address the problem that the existing air compressor operation combination mode, in which the number of units in operation and the exhaust pressure setting value remain basically unchanged, does not clearly define the compressed air demand at the air consumption end and does not adjust according to changes in the air consumption demand, this application provides an air compressor operation setting method.

[0063] Figure 1 A flowchart illustrating an air compressor operation setup method provided in this application embodiment. Figure 1 As shown, the method includes:

[0064] S10: Obtain historical gas consumption data and divide it into multiple gas consumption cycles.

[0065] The gas consumption data differs in each gas consumption cycle.

[0066] In practice, the first step is to acquire historical gas consumption data. This historical data represents gas consumption data from factories or other gas-using scenarios over a preset period prior to the current moment. Within this historical data, time and gas consumption data are correlated one-to-one. For example, gas consumption data for each of the 24 hours within the previous 7 consecutive days can be collected.

[0067] Multiple gas consumption cycles are defined based on historical gas consumption. It's understandable that in actual production processes, the demand for compressed air in factories and other gas-consuming scenarios is not constant but fluctuates. If a uniform gas supply method is used, it may lead to a mismatch between gas production and consumption, resulting in excessive gas production and waste, or insufficient gas production, adversely affecting the production process.

[0068] Therefore, to enable the air compressor operation combination to produce and supply gas more effectively and in a targeted manner, this embodiment needs to divide the gas consumption data into multiple gas consumption cycles, determining the time boundary points of different gas consumption cycles. This results in different gas consumption data within each gas consumption cycle, specifically, larger differences in gas consumption between different gas consumption cycles and smaller differences in gas consumption within the same gas consumption cycle. By dividing the gas consumption cycle, a more comprehensive understanding of the changing trends in gas consumption in different scenarios can be obtained, providing a valid basis for recommending the settings of subsequent air compressor operation combinations.

[0069] S11: Obtain the operating combination of multiple air compressors under each gas usage cycle.

[0070] Each operating combination includes at least one air compressor, and the total exhaust volume of each operating combination meets the air demand flow for the application air cycle.

[0071] Furthermore, it is necessary to obtain the operating combinations of multiple air compressors. It is understood that an air compressor operating combination should contain at least one air compressor; in practical applications, multiple air compressors are usually present in the operating combination. It is important to note that the generation of operating combinations is based on the rated pressure values ​​of multiple air compressors and the total discharge volume within the gas usage cycle. The total discharge volume of each operating combination should meet the gas demand flow rate for the application gas cycle. For example, there are three air compressors, A, B, and C, with the same rated pressure value and a discharge volume of 200m³ / h each. 3 / min, 200m 3 / min, 100m 3 / min; when the periodic gas demand flow rate of the gas consumption scenario is 500m³ / min. 3 When the gas consumption rate is 1 / min, the three air compressors A, B, and C combined can meet the periodic gas consumption demand of the current gas usage scenario. Therefore, the three air compressors A, B, and C can form an operating combination.

[0072] S12: Obtain the set pressure value and total power value of each operating combination under each gas consumption cycle.

[0073] After obtaining the gas consumption cycle and multiple operating combinations, to ensure normal production needs, while meeting the gas flow requirements within the gas consumption cycle, it is also necessary to lower the set pressure value of the operating combinations and estimate the total power of the operating combinations. Specifically, the set pressure value and total power value of each operating combination under each gas consumption cycle are obtained so that the operating combinations can be screened based on the total power value later.

[0074] In this embodiment, there are no restrictions on the specific methods for obtaining the set pressure value and total power value of the operating combination; the specific implementation method will be determined accordingly.

[0075] S13: Select the target operating combination from each operating combination according to the corresponding total power value, so as to output and set the target operating combination and set pressure value under the application gas cycle.

[0076] Finally, based on the corresponding total power value, a target operating combination is selected from each operating combination to output and set the target operating combination and set pressure value for the application gas cycle. It can be understood that the target operating combination is the ultimately recommended operating combination of the air compressor for the gas cycle; different gas cycles correspond to their own target operating combinations.

[0077] It should be noted that the selection process for the target operating combination is not limited in this embodiment. It can be selected based on the relationship between the total power and the threshold, or based on the relationship between the total power values, depending on the specific implementation. There is also no limit to the number of target operating combinations selected; an optimal target operating combination can be selected, or multiple target operating combinations can be selected, depending on the specific implementation.

[0078] In this embodiment, historical gas consumption data is acquired and divided into multiple gas consumption cycles, each with different gas consumption data. Multiple air compressor operating combinations are obtained for each gas consumption cycle, with each operating combination containing at least one air compressor. The total discharge capacity of each operating combination meets the gas demand flow rate for the application gas cycle. The set pressure and total power values ​​of each operating combination for each gas consumption cycle are acquired. Based on the corresponding total power value, a target operating combination is selected from each operating combination to output and set the target operating combination and set pressure value for the application gas cycle. Therefore, the above scheme divides gas consumption cycles with different gas consumption data using historical gas consumption data. By combining different gas consumption cycles, it recommends selecting air compressor operating combinations and set pressure values ​​that meet the requirements of the application gas cycle, achieving more accurate and intelligent selection of air compressor operating combinations. This achieves the goal of matching gas production with gas consumption, reducing waste from excessive gas production, curbing the adverse effects of insufficient gas production on the production process, and realizing a balance between compressed air supply and demand. At the same time, by eliminating the limitations of human experience, the workflow is standardized, improving the operating efficiency and lifespan of air compressors, and enabling widespread adoption.

[0079] To better obtain the operating combinations, based on the above embodiments, as a preferred embodiment, obtaining the operating combinations of multiple air compressors under each gas consumption cycle includes:

[0080] S100: Obtain the gas demand flow rate for the gas consumption cycle;

[0081] S101: Collects operating data from multiple air compressors.

[0082] The operating data should include at least the rated power value, rated flow rate value, rated pressure value, guide vane opening value, actual pressure value, and actual pressure set value.

[0083] S102: Preprocess each running data to remove abnormal running data.

[0084] S103: Generate operating combinations for multiple gas consumption cycles based on gas demand flow rate and pre-processed operating data.

[0085] Since the generation of operating combinations is based on the rated pressure values ​​of multiple air compressors and the total discharge volume within the air usage cycle, the total discharge volume of the operating combinations should meet the air demand flow rate for the application air cycle. Therefore, in specific implementation, the air demand flow rate for the application air cycle must first be determined. Further, operating data of multiple air compressors within the air usage scenario is collected. This operating data includes at least the rated power value, rated flow rate value, rated pressure value, guide vane opening value, actual pressure value, and actual pressure setpoint. It is important to note that the guide vane opening value refers to the shortest distance from the end of any guide vane within the air compressor to the adjacent guide vane; it is a characteristic parameter representing the position of the guide vane during flow regulation. Further preprocessing of each operating data point is performed to remove abnormal operating data. For example, if the collected rated flow rate value is null, or the power value is higher than the rated power value, the abnormal value is removed from the sample. Finally, operating combinations for multiple air usage cycles are generated based on the air demand flow rate for the air usage cycle and the preprocessed operating data.

[0086] In this embodiment, by acquiring the gas demand flow rate of the gas consumption cycle, collecting the operating data of multiple air compressors, and preprocessing the operating data, the operating combinations of air compressors under multiple gas consumption cycles are generated by using the gas demand flow rate and the preprocessed data, thus ensuring the accuracy and reliability of subsequent calculations and analyses.

[0087] Based on the above embodiments, as a preferred embodiment, obtaining the set pressure value and total power value of each operating combination under each gas consumption cycle includes:

[0088] S120: Obtain the gas flow range and minimum required pressure value corresponding to the gas consumption cycle.

[0089] S121: Obtain the actual gas flow rate within the gas flow rate range.

[0090] S122: Obtain the minimum actual pressure value of the operating combination based on the actual gas flow rate and the rated pressure and rated flow rate of the air compressor in the operating combination.

[0091] S123: Determine whether the minimum actual pressure value is not greater than the minimum required pressure value; if yes, proceed to step S124; if no, proceed to step S125.

[0092] S124: Set the minimum required pressure value to the set pressure value.

[0093] S125: Set the minimum actual pressure value to the set pressure value.

[0094] S126: Obtain the total power value of the operating combination based on the set pressure value and the rated power value and rated pressure value of the air compressor in the operating combination.

[0095] In practical implementation, to select a suitable operating combination, it is necessary to explore the lowest actual pressure value that the operating combination can be set. Specifically, first, the gas flow rate range and minimum required pressure value under the gas consumption cycle are obtained, and then the actual gas flow rate value within the gas flow rate range is obtained. Further, based on the actual gas flow rate value and the rated pressure and rated flow rate values ​​of the air compressors within the operating combination, the lowest actual pressure value of the operating combination is obtained. This lowest actual pressure value is the pressure value that meets the actual gas flow rate within the gas consumption cycle. The calculation process is as follows:

[0096] P 实际 =P 额定 ×(Q 实际 / Q 额定 ) 2 ;

[0097] Among them, P 实际 This refers to the actual pressure value, which is also the minimum actual pressure value; P 额定 Q is the rated pressure value. 实际 Q represents the actual gas flow rate during the gas consumption cycle. 额定 This is the rated flow rate.

[0098] Further power estimation is performed to determine if the minimum actual pressure value is not greater than the minimum required pressure value. If so, the minimum required pressure value is set as the set pressure value; otherwise, the minimum actual pressure value is set as the set pressure value to ensure that the set pressure value of the operating combination can meet the minimum required pressure value during the gas usage cycle. Based on the set pressure value and the rated power and rated pressure values ​​of the air compressors in the operating combination, the total power value of the operating combination is obtained. The calculation process is as follows:

[0099] N 实际 =N 额定 ×(P 设定 / P 额定 ) 1.5 ;

[0100] Where, N 实际 This refers to the actual power value, i.e., the final total power value; N 额定 This is the rated power value; P 设定 To set the pressure value; P 额定 This is the rated pressure value.

[0101] In this embodiment, when setting the set pressure value for the operating cycle, the minimum required pressure under the gas consumption cycle is met, ensuring that the operating combination meets the gas consumption requirements of the gas consumption cycle.

[0102] To better select the target operating combination, based on the above embodiments, as a preferred embodiment, selecting the target operating combination from each operating combination according to the corresponding total power value includes:

[0103] S130: Obtain the minimum total power value among all operating combinations.

[0104] S131: Set the threshold based on the minimum value.

[0105] S132: Determine whether the total power value of each operating combination is less than the threshold; if so, proceed to step S133.

[0106] S133: Select the operating combination whose corresponding total power value is less than the threshold as the target operating combination.

[0107] Specifically, to select the target operating combination, the minimum total power value among all operating combinations is first obtained, and a threshold is set based on this minimum value. This embodiment does not limit the specific method of setting the threshold; it depends on the specific implementation. In some embodiments, a multiple of the minimum value can be set as the threshold; for example, when the minimum value is M, 1.1M is set as the threshold. Further, it is determined whether the total power value of each operating combination is less than the threshold; if so, the operating combination with the corresponding total power value less than the threshold is selected as the target operating combination. It should be noted that since the threshold setting is based on the minimum total power value among all operating combinations, at least one operating combination will have a total power value less than the threshold, and thus be selected as the target operating combination.

[0108] In some embodiments, the total power of multiple operating combinations may meet a threshold requirement and can be selected as the target operating combination. Therefore, considering reducing the workload of the air compressor, based on the above embodiments, as a preferred embodiment, selecting operating combinations with a total power value less than the threshold as the target operating combination includes:

[0109] S140: Get the number of running combinations whose total power value is less than the threshold.

[0110] S141: If there is only one operating combination whose total power value is less than the threshold, then that operating combination is selected as the target operating combination.

[0111] S142: If there are multiple operating combinations with a total power value less than the threshold, then generate a set of candidate operating combinations and select the two candidate operating combinations with the lowest total power value from the set of candidate operating combinations.

[0112] S143: Select the target running combination from the two candidate running combinations.

[0113] Specifically, the number of operating combinations with a total power value less than a threshold is obtained. If there is only one operating combination with a total power value less than the threshold, that operating combination is selected as the target operating combination. If there are multiple operating combinations with a total power value less than the threshold, a set of candidate operating combinations is generated. It is understood that the set of candidate operating combinations contains multiple candidate operating combinations. Further, the total power value of each candidate operating combination is obtained from the set of candidate operating combinations, and the two candidate operating combinations with the lowest total power values ​​are selected. The target operating combination is then selected from these two candidate operating combinations. In this embodiment, the specific process of selecting the target operating combination from two candidate operating combinations is not limited and depends on the specific implementation.

[0114] In this embodiment, by obtaining the number of operating combinations whose total power value is less than a threshold, when there are multiple candidate operating combinations that can be selected as the target operating combination, further selection is made among the multiple candidate operating combinations while meeting the actual gas flow rate value within the gas consumption cycle, taking into account reducing the workload of the air compressor, thereby achieving a more reasonable selection of the target operating combination.

[0115] Based on the above embodiments, as a preferred embodiment, selecting the target running combination from the two candidate running combinations includes:

[0116] S150: Obtain the guide vane opening value of each air compressor under different operating conditions in each candidate operating combination.

[0117] S151: Generate regression curves for the guide vane opening value and actual power value of each air compressor under the corresponding actual pressure value.

[0118] S152: Based on the corresponding regression curve, obtain the actual power value of the candidate operating combination under each operating condition within the gas consumption cycle.

[0119] S153: Based on the actual power value under each operating condition within the gas consumption cycle and the proportion of the operating time of each operating condition within the gas consumption cycle, obtain the average power of the candidate operating combination within the gas consumption cycle.

[0120] S154: Select the candidate operating combination with the smaller corresponding average power from the two candidate operating combinations as the target operating combination.

[0121] To ultimately select the target operating combination from the candidate operating combinations, as a preferred embodiment, it is first necessary to obtain the guide vane opening value of each air compressor in each candidate operating combination under different operating conditions. In this embodiment, it is assumed that the guide vane opening value and the flow rate have a linear relationship, and the guide vane opening value of each air compressor is determined specifically under different operating conditions with different flow rate requirements.

[0122] Further, regression curves are generated for the guide vane opening value and actual power value of each air compressor under the corresponding actual pressure value. In the regression curve, the closer the goodness-of-fit test is to 1, the better the model fit. In this embodiment, the specific fitting process of the regression curve is not limited and depends on the specific implementation. The regression curve can be used to find the actual power value corresponding to the set pressure value and guide vane opening value under each production condition within the application air cycle.

[0123] At this point, the target operating combination is determined. Specifically, based on the actual power value under each operating condition within the gas consumption cycle and the proportion of the operating time of each operating condition within the gas consumption cycle, the average power of the candidate operating combination within the gas consumption cycle is obtained. The calculation process is as follows:

[0124]

[0125] Where, N 平均 Let N be the average power of the candidate operating combination, i be the operating condition corresponding to the flow demand under the gas consumption cycle, and N be the operating value. i Let T be the actual power under the i-th operating condition. i Let be the percentage of the operating time of the i-th operating condition within the application gas cycle.

[0126] Finally, after obtaining the average power of the candidate operating combinations, the candidate operating combination with the smaller corresponding average power is selected from the two candidate operating combinations as the target operating combination.

[0127] In this embodiment, by calculating the average power of the candidate operating combinations, the target operating combination with the smaller average power is selected from the two candidate operating combinations. This reduces the operating load of the air compressor in the target operating combination and improves the operating life of the air compressor.

[0128] Furthermore, based on the above embodiments, as a preferred embodiment, after outputting and setting the target operating combination and set pressure value under the applied gas cycle, the method further includes:

[0129] S14: Set an overall operation plan based on the target operating combination and set pressure value under each gas consumption cycle, so that each air compressor can operate according to the overall operation plan.

[0130] Specifically, after selecting the corresponding target operating combinations and set pressure values ​​for all gas consumption cycles, in order to ensure that the operating combinations of each air compressor in the gas consumption scenario can operate in an orderly manner, an overall operating plan can be set according to the target operating combinations and set pressure values ​​under each gas consumption cycle. The overall operating plan sets the target operating combinations that need to be started in each gas consumption cycle in chronological order and sets the corresponding set pressure values. Thus, each air compressor in the gas consumption scenario can operate according to the overall operating plan, achieving a match between gas production and gas consumption throughout the entire production process, reducing waste from excessive gas production, and curbing the adverse effects of insufficient gas production on the production process.

[0131] In the above embodiments, the air compressor operation setting method has been described in detail. This application also provides embodiments corresponding to the air compressor operation setting device.

[0132] Figure 2 This is a schematic diagram of an air compressor operation setting device provided in an embodiment of this application. Figure 2 As shown, the device includes:

[0133] The first acquisition module 10 is used to acquire historical gas consumption data and divide it into multiple gas consumption cycles; wherein the gas consumption data in each gas consumption cycle is different.

[0134] The second acquisition module 11 is used to acquire the operating combinations of multiple air compressors under each gas consumption cycle; wherein, the operating combination includes at least one air compressor, and the total exhaust volume of each operating combination meets the gas consumption demand flow for the application gas cycle.

[0135] The third acquisition module 12 is used to acquire the set pressure value and total power value of each operating combination under each gas consumption cycle.

[0136] Select module 13 is used to select the target operating combination from each operating combination according to the corresponding total power value, so as to output and set the target operating combination and set pressure value under the application gas cycle.
