This eliminates flow rate errors caused by environmental pressure and temperature deviations, resulting in a converted actual air inlet flow rate data. This effectively improves the accuracy of the actual air inlet flow rate data. An energy consumption ratio algorithm is used to calculate the ratio between the actual air inlet flow rate data and the unit power data, yielding an actual energy consumption ratio value that can be used to evaluate energy consumption. Preset energy consumption monitoring conditions are used as energy consumption reference indicators to monitor the actual energy consumption ratio value in real time. The actual energy consumption ratio value is monitored according to different environmental factors to improve the sensitivity and accuracy of monitoring. If the actual energy consumption ratio value is abnormal, it indicates that a module of the air compressor may be malfunctioning, causing abnormal energy consumption. Therefore, alarm data is generated to alert the user, enabling the user to quickly troubleshoot the air compressor.

It should be understood that such data can be interchanged where appropriate so that the embodiments described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" or "having," and any variations thereof, are intended to cover a non-exclusive inclusion.

[0029] For example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or that are inherent to those processes, methods, products, or devices.

[0030] For ease of understanding, the specific process of the embodiments of the present invention is described below. Please refer to [link / reference]. Figure 1 One embodiment of the air compressor energy consumption monitoring method of the present invention includes:

[0034] 104. The actual energy consumption ratio value is obtained by calculating the actual flow rate data of the air intake and the power data of the unit through the energy consumption ratio algorithm.

[0035] In this embodiment, pressure sensors, temperature sensors, power meters, and flow meters are used to acquire real-time environmental data, air compressor inlet environmental data, air compressor inlet flow data, and unit power data of the air compressor to obtain basic data for monitoring. Then, the real-time environmental data, air compressor inlet environmental data, and air compressor inlet flow data are calculated using an actual air compressor flow algorithm to correct the air compressor inlet flow data, correcting some flow errors caused by environmental pressure and temperature deviations, to obtain the converted actual intake flow data. This method effectively improves the accuracy of the actual intake flow data. In addition, an energy consumption ratio algorithm is used to calculate the ratio between the actual intake flow data and the unit power data to obtain an index data (i.e., actual energy consumption ratio value) that can be used to evaluate energy consumption. This allows users to judge the actual operating status of the air compressor based on the actual energy consumption ratio value. If the actual energy consumption ratio value is abnormal, users can troubleshoot the components in the air compressor.

[0036] 105. Monitor the actual energy consumption ratio according to the preset energy consumption monitoring conditions. If the actual energy consumption ratio does not meet the preset energy consumption monitoring conditions, generate alarm data based on the actual energy consumption ratio.

If a module malfunctions and causes abnormal energy consumption, alarm data is generated to monitor the actual energy consumption ratio based on the user's environmental factors (i.e., atmospheric pressure and ambient temperature) to improve the sensitivity and accuracy of monitoring. If the actual energy consumption ratio is abnormal, it indicates that the air compressor may be malfunctioning and an alert is issued so that the user can quickly troubleshoot the air compressor.

[0038] In this embodiment of the invention, the actual air compressor flow rate algorithm, combined with real-time environmental data and air compressor supply port environmental data, is used to correct the air compressor supply port flow rate data. This eliminates some flow rate errors caused by environmental pressure and temperature deviations, resulting in a converted actual air intake port flow rate data. This method effectively improves the accuracy of the actual air intake port flow rate data. An energy consumption ratio algorithm is used to calculate the ratio between the actual air intake port flow rate data and the unit power data, yielding an actual energy consumption ratio value that can be used to evaluate energy consumption. Preset energy consumption monitoring conditions are used as energy consumption reference indicators to monitor the actual energy consumption ratio value in real time. The actual energy consumption ratio value is monitored according to different environmental factors to improve the sensitivity and accuracy of monitoring. If the actual energy consumption ratio value is abnormal, it indicates that a certain module of the air compressor may have malfunctioned, causing abnormal energy consumption. Therefore, alarm data is generated to alert the user, enabling the user to quickly troubleshoot the air compressor.

[0044] In this embodiment, real-time environmental data, air compressor inlet environmental data, and air compressor inlet flow rate data are filtered to obtain a value q that can be used to calculate the actual flow rate at the intake port. v The parameters are used to calculate the flow rate F at the air supply test point using the ambient atmospheric pressure P1, the intake ambient temperature T1, the supply ambient pressure P2, and the supply ambient temperature T2, in order to deduce the actual flow rate q at the intake. v It can provide effective and accurate basic parameters for the conversion of energy consumption index values.

[0045] Furthermore, the actual flow rate algorithm of the air compressor calculates the actual flow rate q at the intake port based on the ambient atmospheric pressure P1, the intake port ambient temperature T1, the supply port ambient pressure P2, the supply port ambient temperature T2, and the flow rate F at the supply port test point. v ,include:

[0046] q v =F*(P1+P2)*(A+T1) / (A+T2) / P1,

[0047] Where A is the Kelvin temperature constant, A = 273.15.

[0048] In this embodiment, the ambient temperature values ​​T1 at the intake port and T2 at the supply port are converted using the Kelvin temperature constant to convert Celsius to Kelvin temperature, thereby standardizing the temperature parameters and reducing the computational load of the actual flow rate algorithm of the air compressor.

If the difference between the actual energy consumption ratio X and its corresponding standard energy consumption ratio X1 is greater than the preset difference, generate alarm data.

[0061] In this embodiment, the standard energy consumption ratio value X1 is pre-calculated according to different working scenarios (i.e., different atmospheric pressure environments and different temperature working environments) to obtain multiple standard energy consumption ratio values ​​X1 under different usage scenarios.

The monitoring module 605 uses preset energy consumption monitoring conditions as energy consumption reference indicators to monitor the actual energy consumption ratio value in real time. It monitors the actual energy consumption ratio value according to different environmental factors to improve the sensitivity and accuracy of monitoring.

The second calculation module is used to calculate the actual flow rate data of the air intake and the power data of the unit through the energy consumption ratio algorithm to obtain the actual energy consumption ratio value. The monitoring module is used to monitor the actual energy consumption ratio based on preset energy consumption monitoring conditions. If the actual energy consumption ratio does not meet the preset energy consumption monitoring conditions, alarm data is generated based on the actual energy consumption ratio.
