Description

Technical Field

[0001] The present invention relates to the technical field of energy-saving control of air compressor stations, and in particular to an energy-saving control system of an air compressor station based on operation monitoring. Background Art

[0002] Air compression stations are important places for providing compressed air in industrial production. They consume a lot of electricity during operation. Currently, after professionals select and match air compressors and subsequent processing equipment such as cold dryers, air storage tanks, filters and adsorption dryers, users usually install the air compressors and subsequent processing equipment such as cold dryers, air storage tanks, filters and adsorption dryers separately in the air compression station room.

[0003] During the operation of existing air compression stations, on the one hand, the air compressor cannot accurately match the actual gas demand. When the actual gas consumption is small, the air compressor still runs at a high power, resulting in energy waste. On the other hand, there is a lack of effective coordination mechanism between the collaborative work of multiple air compressors in the air compression station. Each air compressor operates independently and cannot achieve the optimal combined operation according to the changes in the overall gas consumption, further reducing energy utilization efficiency. In addition, it is impossible to rationalize energy-saving replacement according to the operating status of the air compressor in the air compression station, which leads to an increased risk of abnormal energy consumption in the air compression station and the problem of energy waste in the air compression station.

[0004] In view of the above technical defects, a solution is now proposed. Summary of the Invention

[0005] The purpose of the present invention is to provide an energy-saving control system for an air compressor station based on operation monitoring to solve the technical defects mentioned above. The present invention initially analyzes from the perspective of the status of the air compressor in the air compressor station, divides the air compressor into dynamic air compressors and static air compressors, and performs discrimination analysis based on the energy consumption of the dynamic air compressor, so as to perform energy-saving management of the air compressor station according to the information feedback to reduce the risk of abnormal energy consumption. At the same time, in-depth analysis is performed from the perspective of energy consumption tracking to achieve energy-saving management of dynamic air compressors with abnormal energy consumption and reduce unnecessary energy consumption losses. The normal efficiency coefficient of the static air compressor of the same type is rationally replaced to achieve the effect of intelligent energy-saving replacement. At the same time, the dynamic air compressor and the static air compressor in the air compressor station are rationally started and stopped according to the gas demand of the air compressor station, thereby achieving the effect of energy-saving control and avoiding the problem of energy waste.

[0006] The object of the present invention can be achieved by the following technical solutions: an air compressor station energy-saving control system based on operation monitoring, comprising an air compressor station energy-saving control platform, an energy-saving supervision unit, a state division unit, an energy-saving replacement unit, an energy-saving control unit and an energy-saving management unit;

If the time period deviation value is equal to zero, a normal signal is generated, and the corresponding dynamic air compressor is judged to be a normal device. If the time period deviation value is not equal to zero, an abnormal signal is generated, and the corresponding dynamic air compressor is judged to be an abnormal device.

[0014] Preferably, the rational replacement consumption reduction processing analysis process is as follows:

[0015] Obtain the exhaust flow corresponding to the abnormal device, obtain the static air compressor corresponding to the same exhaust flow, and set the static air compressor corresponding to the same exhaust flow as the replacement air compressor;

[0016] The maximum and minimum working efficiency values ​​of each replacement air compressor are obtained, and at the same time, the total operating energy consumption value of each replacement air compressor within the time threshold is obtained, and the ratio between the maximum working efficiency and the total operating energy consumption value is set as the period performance peak value, and the ratio between the minimum working efficiency value and the total operating energy consumption value is set as the period performance valley value, and half of the sum of the period performance peak value and the period performance valley value is set as the normal efficiency coefficient, and the normal efficiency coefficients are sorted in order from large to small, and the first replacement air compressor corresponding to the sorted normal efficiency coefficient is set as the first selected air compressor.

When a feedback instruction is generated, the number of static air compressors in each exhaust combination is obtained and set as the running number, and the exhaust combination corresponding to the minimum value in the running number is set as the preferred exhaust combination;

[0020] Obtain the normal efficiency coefficient of the static air compressor in each preferred exhaust combination, and perform discrimination processing on the normal efficiency coefficient. If the normal efficiency coefficient is the maximum value, the corresponding static air compressor is determined to be the preferred device; if the normal efficiency coefficient is not the maximum value, the corresponding static air compressor is determined to be the alternative device;

[0021] The proportion values ​​of the preferred devices in each exhaust combination are obtained, and the exhaust combination corresponding to the maximum proportion value of the preferred devices is set as the preferred energy-saving combination.

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] References to "embodiments" herein mean that a particular feature, structure, or characteristic described in connection with the embodiment may be included in at least one embodiment of the present invention. The appearance of the phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute a separate or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments;

[0030] Example 1:

[0031] See also Figures 1 to 2 As shown, the present invention is an energy-saving control system for an air compressor station based on operation monitoring, comprising an energy-saving control platform for the air compressor station, an energy-saving supervision unit, a state division unit, an energy-saving replacement unit, an energy-saving control unit, and an energy-saving management unit. The energy-saving control platform for the air compressor station is connected to the energy-saving supervision unit in a one-way communication manner, the energy-saving supervision unit is connected to the state division unit, the energy-saving control unit, and the energy-saving management unit in a one-way communication manner, the state division unit is connected to the energy-saving replacement unit in a one-way communication manner, the energy-saving replacement unit is connected to the energy-saving management unit in a one-way communication manner, and the energy-saving control unit is connected to the energy-saving management unit in a one-way communication manner;

[0032] The air compressor station energy-saving control platform is used to retrieve the operating status information of each air compressor in the air compressor station and send the operating status information to the energy-saving supervision unit for abnormal energy consumption safety supervision analysis, so as to perform energy-saving management of the air compressor station based on the information feedback to reduce the risk of abnormal energy consumption. The specific abnormal energy consumption safety supervision analysis process is as follows:

[0033] The operating time period of the air compressor station is collected and set as a time threshold. The operating status information of each air compressor in the air compressor station within the time threshold is obtained. The operating status information includes an operating state and a standby state. The operating status information of the air compressor is judged and processed. If the operating status information is an operating state, the corresponding air compressor is judged to be a dynamic air compressor. If the operating status information is a standby state, the corresponding air compressor is judged to be a static air compressor.

[0034] Obtain the operating energy consumption data of all dynamic air compressors within the time threshold. The operating energy consumption data includes the total operating energy consumption value and the total ineffective operating energy consumption value. The total ineffective operating energy consumption value represents the total energy consumed by the dynamic air compressor in the form of heat loss, no-load, etc.

[0035] The value obtained by subtracting the total invalid operating energy consumption from the total operating energy consumption is set as the effective operating energy consumption. The ratio between the effective operating energy consumption and the total operating energy consumption is set as the effective proportion. The value obtained by subtracting the set effective proportion from the effective proportion is set as the effective floating value, and the effective floating value is discriminated:

[0036] If the effective floating value is greater than or equal to the preset effective floating value threshold, a stable signal is generated;

[0037] If the effective floating value is less than the preset effective floating value threshold, a fluctuation signal is generated. The energy-saving management unit responds to the stable signal or the fluctuation signal and immediately performs the preset warning operation corresponding to the stable signal or the fluctuation signal, so as to perform energy-saving management of the air compressor station based on the information feedback and reduce the risk of abnormal energy consumption;

[0038] When a fluctuation signal is generated, the state division unit is used to perform energy consumption interference tracking and feedback analysis on the collected operating parameter information of the dynamic air compressor, and then conduct targeted management of the dynamic air compressors in the air compression station, so as to achieve energy-saving management of dynamic air compressors with abnormal energy consumption and reduce unnecessary energy consumption losses. The specific energy consumption interference tracking and feedback analysis process is as follows:

[0039] The operating parameter information of each dynamic air compressor within the time threshold is obtained, and the operating parameter information includes exhaust pressure, exhaust flow, operating current, etc. The amplitude mean corresponding to the operating parameter information within the time threshold is obtained, and the amplitude mean corresponding to the operating parameter information is set as the time period operating parameter information, and the time period operating parameter information is judged and processed, and the number of parameter values ​​in the time period operating parameter information that exceeds the preset threshold is set as the time period deviation value, and the time period deviation value is judged and processed. If the time period deviation value is equal to zero, a normal signal is generated, and the corresponding dynamic air compressor is judged to be a normal device. If the time period deviation value is not equal to zero, an abnormal signal is generated, and the corresponding dynamic air compressor is judged to be an abnormal device. The energy-saving management unit responds to the normal signal and the abnormal signal, and the normal device corresponding to the normal signal is marked green, and the abnormal device corresponding to the abnormal signal is marked red, and then the dynamic air compressor in the air compression station is targeted for management, so as to achieve energy-saving management of dynamic air compressors with abnormal energy consumption and reduce unnecessary energy consumption losses.

[0040] Example 2:

[0041] Analyze from the perspective of abnormal equipment replacement, and then make reasonable replacement based on the normal efficiency coefficient of the same type of static air compressor, so as to achieve the effect of intelligent energy-saving replacement;

[0042] When an abnormal signal is generated, the energy-saving replacement unit is used to perform a reasonable replacement and consumption reduction processing analysis on the exhaust flow corresponding to the abnormal equipment collected, thereby achieving the effect of intelligent energy-saving replacement and helping to effectively control the energy saving of the air compressor station. The specific reasonable replacement and consumption reduction processing analysis process is as follows:

[0043] Obtain the exhaust flow corresponding to the abnormal device, obtain the static air compressor corresponding to the same exhaust flow, and set the static air compressor corresponding to the same exhaust flow as the replacement air compressor;

[0044] The maximum and minimum working efficiency values ​​of each replacement air compressor are obtained, and the total operating energy consumption value of each replacement air compressor within the time threshold is obtained. The ratio between the maximum working efficiency and the total operating energy consumption value is set as the performance peak value of the period, and the ratio between the minimum working efficiency and the total operating energy consumption value is set as the performance valley value of the period. Half of the sum of the performance peak value and the performance valley value of the period is set as the normal efficiency coefficient. The normal efficiency coefficients are sorted in descending order, and the first replacement air compressor corresponding to the sorted normal efficiency coefficient is set as the first selected air compressor. The energy-saving management unit controls the shutdown of the abnormal equipment and starts the first selected air compressor corresponding to the abnormal equipment, thereby achieving the effect of intelligent replacement, that is, the abnormal equipment is replaced sequentially according to the sorted normal efficiency coefficients, and at the same time helps to effectively control the energy saving of the air compressor station.

[0045] Among them, it should be noted that the normal efficiency coefficient is an evaluation coefficient that reflects the low-consumption and high-efficiency operation of the static air compressor. The larger the value of the normal efficiency coefficient, the better the energy-saving effect of the static air compressor.

[0046] When a stable signal is generated, the energy-saving control unit is used to perform equipment energy-saving control management analysis on the total gas consumption of the collected air compression station. That is, it rationalizes the start and stop management of the dynamic air compressor and the static air compressor in the air compression station according to the gas demand of the air compression station, thereby achieving the effect of energy-saving control and avoiding the problem of energy waste. The specific equipment energy-saving control management analysis process is as follows:

[0047] Get the total gas consumption of the air compression station within the time threshold, and also get the sum of the gas consumption of the dynamic air compressors in the air compression station within the time threshold. Set the sum of the dynamic air compressor gas consumption in the air compression station as the started gas consumption, and compare and analyze the total gas consumption with the started gas consumption:

[0048] If the total gas usage is less than the activated gas usage, a reduction signal is generated;

[0049] If the total gas consumption is equal to the activated gas consumption, a normal signal is generated. When the normal signal is generated, energy-saving monitoring continues;

[0050] If the total gas consumption is greater than the activated gas consumption, an increase signal is generated;

[0051] When a reduction signal is generated, the value obtained by subtracting the total gas consumption from the started gas consumption is obtained, and the value obtained by subtracting the total gas consumption from the started gas consumption is set as the reduced displacement. Based on the reduced displacement, the reduced exhaust combination of the dynamic air compressor is obtained, the sum of the operating energy consumption values ​​of the dynamic air compressors in the reduced exhaust combination is obtained, and it is set as the combined energy consumption value, and the reduced exhaust combination corresponding to the maximum value in the combined energy consumption value is set as the first reduction combination. The energy-saving management unit controls the dynamic air compressors in the first reduction combination to be shut down one by one, thereby achieving the effect of intelligent energy-saving control and avoiding the problem of energy waste.

[0052] When an increase signal is generated, the value obtained by subtracting the started gas consumption from the total gas consumption is set as the displacement to be increased, and the exhaust combination of the static air compressor is obtained based on the displacement to be increased;

[0053] For example: when the displacement to be added is 50m 3 / min, start an exhaust flow of 30m 3 / min and an exhaust flow rate of 20m 3 / min static air compressor can meet the gas demand, or start an exhaust flow of 40m 3 / min and an exhaust flow rate of 10m 3 / min static air compressor can meet the gas demand;

[0054] The number of exhaust combinations is obtained and the number of exhaust combinations is judged. If the number of exhaust combinations is equal to 1, an execution signal is generated. When the execution signal is generated, the energy-saving management unit responds to the execution signal and immediately starts the static air compressor corresponding to the exhaust combination;

[0055] If the number of exhaust combinations is not equal to 1, a feedback instruction is generated. When the feedback instruction is generated, the number of static air compressors in each exhaust combination is obtained and set as the running number. The exhaust combination corresponding to the minimum running number is set as the preferred exhaust combination. The requirements can be met with a small number of static air compressors, which facilitates rapid control and management.

[0056] Obtain the normal efficiency coefficient of the static air compressor in each preferred exhaust combination, and perform discrimination processing on the normal efficiency coefficient. If the normal efficiency coefficient is the maximum value, the corresponding static air compressor is determined to be the preferred device; if the normal efficiency coefficient is not the maximum value, the corresponding static air compressor is determined to be the alternative device;

[0057] The proportion values ​​of the preferred devices in each exhaust combination are obtained, and the exhaust combination corresponding to the maximum proportion value of the preferred devices is set as the preferred energy-saving combination. The energy-saving management unit responds to the preferred energy-saving combination and immediately controls each static air compressor in the preferred energy-saving combination to work, thereby achieving the effect of energy-saving control, so that the static air compressor combination can achieve maximum energy saving;

[0058] In summary, the present invention preliminarily analyzes from the perspective of the status of the air compressor in the air compressor station, divides the air compressor into dynamic air compressors and static air compressors, and performs discrimination analysis based on the energy consumption of the dynamic air compressor, so as to perform energy-saving management of the air compressor station according to the information feedback, so as to reduce the risk of abnormal energy consumption. At the same time, it conducts in-depth analysis from the perspective of energy consumption tracking, and performs targeted management of the dynamic air compressor in the air compressor station, so as to achieve energy-saving management of the dynamic air compressor with abnormal energy consumption and reduce unnecessary energy consumption losses. From the perspective of abnormal equipment replacement, that is, reasonable replacement of the normal efficiency coefficient of the static air compressor of the same type is carried out, which helps to effectively control the energy saving of the air compressor station, thereby achieving the effect of intelligent energy-saving replacement. At the same time, according to the gas demand of the air compressor station, the dynamic air compressor and the static air compressor in the air compressor station are rationally managed to achieve the effect of energy-saving control and avoid the problem of energy waste.

[0059] The threshold is set to facilitate comparison. The size of the threshold depends on the amount of sample data and the number of bases set by technicians in this field for each set of sample data; as long as it does not affect the proportional relationship between the parameter and the quantized value.

[0060] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
