[0022] Please refer to Figure 1 , Figure 1 This is a flow chart of a pump group energy saving and consumption reduction intelligent control method in some embodiments of the present application. This pump group energy saving and consumption reduction intelligent control method is used in terminal equipment, such as computers, mobile terminals, etc. This pump group energy saving and consumption reduction intelligent control method includes the following steps: S101, obtaining energy efficiency parameter information of the pump group in a preset area under a preset environment to extract flow stability data, head capacity data and pump group energy consumption data; S102, comparing the flow stability data with a preset stability threshold to determine whether the flow stability meets the requirement, and comparing the lift capacity data with a preset capacity threshold to determine whether the lift capacity meets the requirement; S103, processing the flow stability data, the head capacity data and the pump group energy consumption data to obtain a pump group energy efficiency index; S104, performing correction processing according to the pump group energy efficiency index to obtain a pump group energy efficiency correction index; S105 .

[0023] Among them, the present application obtains the pump group energy efficiency parameter information in a preset area under a preset environment to extract flow stability data, head capacity data and pump group energy consumption data, compares the flow stability data with the preset stability threshold, and judges whether the flow stability meets the requirements, compares the head capacity data with the preset capacity threshold, and judges whether the head capacity meets the requirements, and then processes the flow stability data, head capacity data and pump group energy consumption data in combination with the pump group pipeline layout characteristic data to obtain the pump group energy efficiency index, and then corrects the pump group energy efficiency index according to the average energy efficiency index of pump groups in multiple different areas with the same preset environment to obtain the pump group energy efficiency correction index, which is compared with the preset energy efficiency index threshold to judge whether the pump group energy efficiency meets the requirements. This application not only takes into account the two key performance indicators of flow stability and head capacity, but also introduces the energy consumption and pipeline layout characteristic data of the pump group, comprehensively evaluates the energy efficiency of the pump group from multiple angles, and corrects the pump group energy efficiency index by introducing the average energy efficiency index of the pump group in multiple different areas with the same preset environment. It takes into account regional differences and differences between pump groups, improves the accuracy and reliability of the evaluation results, and comprehensively considers multiple factors such as the operating performance, energy consumption and pipeline layout of the pump group, ensuring the comprehensiveness and systematicness of the evaluation, and providing strong data support for the pump group to maintain high-efficiency operation and regular maintenance.

[0024] Please refer to Figure 2 , Figure 2 The flowchart of a pump group energy saving and consumption reduction intelligent control method in some embodiments of the present application for judging whether the flow stability meets the requirements. According to an embodiment of the present invention, the flow stability data is compared with a preset stability threshold to judge whether the flow stability meets the requirements, specifically: S201, comparing the flow stability data with a preset stability threshold; S202, if the flow stability data is less than the stability threshold, obtain flow abnormality data and count them to obtain flow abnormality frequency data; S203, comparing the traffic anomaly number data with a preset anomaly number threshold; S204: If the flow abnormality frequency data is greater than or equal to the abnormality frequency threshold, a pump group flow unstable alarm message is sent.

[0025] Among them, in order to determine whether the flow stability of the pump group meets the requirements, the flow stability data can be obtained by monitoring the flow changes of the pump group in real time and calculating its stability, and then compared with the preset stability threshold. If the flow stability data is less than the stability threshold, it means that the flow stability of the pump group is poor and there may be an abnormality. The flow abnormality data is obtained and counted to obtain the flow abnormality number data, and the flow abnormality number data is compared with the preset abnormality number threshold. If the flow abnormality number data is greater than or equal to the abnormality number threshold, it means that the flow stability of the pump group has not met the requirements for many consecutive times and there may be serious operating problems. In this way, the pump group flow instability alarm information is sent to remind the operator or maintenance personnel to conduct inspections and repairs in time.

[0026] Please refer to Figure 3 , Figure 3 It is a flow chart of a pump group energy saving and consumption reduction intelligent control method in some embodiments of the present application for judging whether the head capacity meets the requirements. According to an embodiment of the present invention, the head capacity data is compared with a preset capacity threshold to judge whether the head capacity meets the requirements, specifically: S301, comparing the lift capacity data with a preset first lift capacity threshold and a preset second lift capacity threshold, wherein the first lift capacity threshold is smaller than the second lift capacity threshold; S302: If the lift capacity data is less than the first lift capacity threshold, the lift capacity of the pump group is too low; S303: If the lift capacity data is greater than or equal to the first lift capacity threshold and less than or equal to the second lift capacity threshold, the lift capacity of the pump group meets the requirement but needs maintenance and adjustment; S304: If the lift capacity data is greater than the second lift capacity threshold, the lift capacity of the pump group is good.

[0027] Among them, in order to determine whether the head capacity of the pump group meets the requirements, the head capacity data is compared with the preset first head capacity threshold and the second head capacity threshold respectively. The head capacity data is obtained through real-time monitoring, reflecting the head size that the pump group can provide under specific working conditions. The first head capacity threshold is less than the second head capacity threshold. If the head capacity data is less than the first head capacity threshold, the head capacity of the pump group is too low and may not be able to meet the needs of normal operation. If the head capacity data is greater than or equal to the first head capacity threshold and less than or equal to the second head capacity threshold, it means that although the head capacity of the pump group meets the current operating requirements, there may be a risk of performance degradation or potential failure. The pump group needs to be maintained and adjusted to ensure its long-term stable operation. If the head capacity data is greater than the second head capacity threshold, the head capacity of the pump group is good and can easily cope with the current and possible future increased load demands.

[0028] Please refer to Figure 4 , Figure 4 The flowchart of obtaining the energy efficiency index of a pump group in an intelligent control method for energy saving and consumption reduction of a pump group in some embodiments of the present application is as follows. According to an embodiment of the present invention, the energy efficiency index of the pump group is obtained by processing the flow stability data, the head capacity data and the energy consumption data of the pump group, specifically: S401, obtaining pump group pipeline layout characteristic data in a preset area under a preset environment; S402, processing the flow stability data, the head capacity data and the pump group energy consumption data in combination with the pump group pipeline layout characteristic data through a preset pump group energy efficiency evaluation model to obtain a pump group energy efficiency index.

[0029] Among them, in order to comprehensively evaluate the efficiency status of the pump group, first obtain the pump group pipeline layout characteristic data in the preset area under the preset environment, including pipeline resistance data, pipeline physical characteristic data and pipeline layout structure data, and process the pump group pipeline layout characteristic data through the preset pump group energy efficiency evaluation model according to the flow stability data, head capacity data and pump group energy consumption data, and obtain the pump group energy efficiency index to reflect the energy efficiency level of the pump group under the current working conditions. By comparing the energy efficiency indexes of different pump groups, their energy efficiency differences can be intuitively evaluated, and data support can be provided for subsequent energy efficiency improvement measures; The calculation formula of the pump group energy efficiency model is: ; in, is the energy efficiency index of the pump group, They are flow stability data, head capacity data, pump unit energy consumption data and pump unit pipeline layout characteristic data. It is the preset characteristic coefficient (the characteristic coefficient is obtained by querying the preset pump group high-efficiency control database).

[0030] Please refer to Figure 5 , Figure 5 It is a flow chart of obtaining a pump group energy efficiency correction index in a pump group energy saving and consumption reduction intelligent control method in some embodiments of the present application. According to an embodiment of the present invention, the pump group energy efficiency correction index is obtained by performing correction processing according to the pump group energy efficiency index, specifically: S501, obtaining and calculating the energy efficiency indexes of the pump groups in a plurality of different areas that are the same as the preset environment, and obtaining an average energy efficiency index of the pump groups; S502 , correcting the pump group energy efficiency index through an energy efficiency index correction model according to the pump group energy efficiency average index to obtain a pump group energy efficiency correction index.

[0031] Among them, in order to further accurately reflect the operating efficiency status of the pump group, firstly, the energy efficiency index of the pump group in multiple different areas that are the same as the preset environment is obtained and calculated to obtain the average energy efficiency index of the pump group, which reflects the general energy efficiency level of the pump group under the preset environment. Then, the energy efficiency index of the pump group is corrected by the energy efficiency index correction model to obtain the energy efficiency correction index of the pump group; The calculation formula of the energy efficiency index correction model is: ; in, is the pump group energy efficiency correction index, is the energy efficiency index of the pump group, is the average energy efficiency index of the pump group, It is the preset characteristic coefficient (the characteristic coefficient is obtained by querying the preset pump group high-efficiency control database).

[0032] According to an embodiment of the present invention, the comparison between the pump group energy efficiency correction index and a preset energy efficiency index threshold is used to determine whether the pump group energy efficiency meets the requirements, specifically: Comparing the pump group energy efficiency correction index with a preset energy efficiency index threshold, obtaining an energy efficiency index deviation rate; Comparing the energy efficiency index deviation rate with a preset index deviation rate threshold; If the energy efficiency index deviation rate is less than the index deviation rate threshold, the pump group is in a high-efficiency operation state; If the energy efficiency index deviation rate is greater than or equal to the index deviation rate threshold, the pump group is in a low-efficiency operation state.

[0033] Among them, in order to determine whether the energy efficiency of the pump group meets the requirements, the energy efficiency correction index of the pump group is compared with the preset energy efficiency index threshold to obtain the energy efficiency index deviation rate, which is compared with the preset index deviation rate threshold. If the energy efficiency index deviation rate is less than the index deviation rate threshold, it means that the energy efficiency operation state of the pump group is good and it is in a high-efficiency operation state. It can be considered that the energy efficiency level of the pump group meets or exceeds the expected standard, and no additional energy efficiency improvement measures are required. If the energy efficiency index deviation rate is greater than or equal to the index deviation rate threshold, it means that the energy efficiency operation state of the pump group is not good and it is in a low-efficiency operation state. The pump group needs to be further improved to improve its energy efficiency level.

[0034] According to an embodiment of the present invention, it also includes: Comparing the energy consumption data of the pump group with a preset energy consumption threshold, obtaining an energy consumption deviation rate; comparing the energy consumption deviation rate with a preset energy consumption deviation rate threshold; If the energy consumption deviation rate is less than the energy consumption deviation rate threshold, the energy consumption of the pump group is within the normal range; If the energy consumption deviation rate is greater than or equal to the energy consumption deviation rate threshold, the energy consumption of the pump group is abnormal.

[0035] Among them, in order to reduce the energy consumption of the pump group, the energy consumption data of the pump group is compared with the preset energy consumption threshold to obtain the energy consumption deviation rate, which is compared with the preset energy consumption deviation rate threshold. If the energy consumption deviation rate is less than the energy consumption deviation rate threshold, it means that the energy consumption of the pump group is within the normal range and meets the expected energy efficiency standards. It can be considered that the energy consumption of the pump group is properly managed and no additional energy consumption improvement measures are required. If the energy consumption deviation rate is greater than or equal to the energy consumption deviation rate threshold, it means that the energy consumption of the pump group is abnormal, and there may be problems of excessive energy consumption or low energy efficiency. Further energy consumption analysis and diagnosis of the pump group are required to find out the cause of the abnormal energy consumption.

[0036] According to an embodiment of the present invention, it also includes: Obtain water demand information of users in a preset area under a preset environment, and extract water consumption data; Comparing the water volume data with a preset water volume threshold; If the water volume data is greater than or equal to the water volume threshold, abnormal water usage data is obtained and timed to obtain abnormal water usage duration data; Comparing the abnormal water use duration data with a preset abnormal time threshold; If the abnormal water usage duration data is greater than or equal to the abnormal time threshold, there is a possibility of failure in the user-side water outlet device and an alarm message is sent.

[0037] Among them, in order to monitor in real time whether the water use at the user end is normal, the water demand information of the user end in a preset area under a preset environment is obtained, the water volume data of the water use is extracted, and compared with the preset water volume threshold. This preset water volume threshold is set according to the normal water use of the user end, historical water use data or industry standards. If the water volume data is greater than or equal to the water volume threshold, the abnormal water use data is obtained and timed, and the water use abnormality duration data is obtained. The water use abnormality duration data is compared with the preset abnormal time threshold. This preset abnormal time threshold is set according to the water use habits of the user end, the equipment maintenance cycle or the industry standard, and is used to determine whether the water use abnormality continues to the extent that attention needs to be paid. If the water use abnormality duration data is greater than or equal to the abnormal time threshold, the water outlet device at the user end may have a fault and send an alarm message, indicating that the water use abnormality at the user end has lasted for a long time, and there may be a risk of water outlet device failure. By sending an alarm message, relevant personnel can be reminded to pay attention to and deal with the abnormal water use problem at the user end in a timely manner to avoid further expansion of the fault or cause unnecessary losses.

[0038] According to an embodiment of the present invention, it also includes: Extracting water volume data, water pressure data, water time data and water period data according to the user-side water demand information; According to the water consumption data, water pressure data, water use time data and water use period data, a preset pump group high-efficiency control database is queried to obtain the corresponding pump group speed data within the pump group high-efficiency range and adjust the pump group speed.

[0039] Among them, in order to maintain the high-efficiency operation state of the pump group and meet the water use demand of the user end, water volume data, water pressure data, water time data and water period data are extracted according to the water use demand information of the user end. The water volume data is obtained by recording the water consumption of the user each time or each time period. The water pressure data is obtained by monitoring the water pressure at the user end to ensure that the water pressure is stable and meets the user's needs. The water time data records the specific time of each water use by the user. The water period data refers to the different time periods when the user habitually uses water. According to the water volume data, water pressure data, water time data and water period data, the preset pump group high-efficiency control database is queried to obtain the corresponding pump group speed data within the pump group high-efficiency range and adjust the pump group speed. The preset pump group high-efficiency control database records the pump group speeds corresponding to different water demands under the high-efficiency operation state of the pump group.

[0040] The present invention also discloses a pump group energy-saving and consumption-reducing intelligent control system, comprising a memory and a processor, wherein the memory comprises a pump group energy-saving and consumption-reducing intelligent control method program, and when the pump group energy-saving and consumption-reducing intelligent control method program is executed by the processor, the following steps are implemented: Obtain the energy efficiency parameter information of the pump group in the preset area under the preset environment to extract the flow stability data, head capacity data and pump group energy consumption data; Comparing the flow stability data with a preset stability threshold value to determine whether the flow stability meets the requirement, and comparing the head capacity data with a preset capacity threshold value to determine whether the head capacity meets the requirement; Processing the flow stability data, the head capacity data and the pump group energy consumption data to obtain a pump group energy efficiency index; Perform correction processing according to the pump group energy efficiency index to obtain a pump group energy efficiency correction index; The pump group energy efficiency correction index is compared with a preset energy efficiency index threshold to determine whether the pump group energy efficiency meets the requirements.

[0044] According to an embodiment of the present invention, comparing the lift capacity data with a preset capacity threshold to determine whether the lift capacity meets the requirement is specifically as follows: Comparing the lift capacity data with a preset first lift capacity threshold and a preset second lift capacity threshold, respectively, the first lift capacity threshold being smaller than the second lift capacity threshold; If the head capacity data is less than the first head capacity threshold, the head capacity of the pump set is too low; If the head capacity data is greater than or equal to the first head capacity threshold and less than or equal to the second head capacity threshold, the head capacity of the pump unit meets the requirements but needs maintenance and adjustment; If the head capacity data is greater than the second head capacity threshold, the head capacity of the pump group is good.

[0045] Among them, in order to determine whether the head capacity of the pump group meets the requirements, the head capacity data is compared with the preset first head capacity threshold and the second head capacity threshold respectively. The head capacity data is obtained through real-time monitoring, reflecting the head size that the pump group can provide under specific working conditions. The first head capacity threshold is less than the second head capacity threshold. If the head capacity data is less than the first head capacity threshold, the head capacity of the pump group is too low and may not be able to meet the needs of normal operation. If the head capacity data is greater than or equal to the first head capacity threshold and less than or equal to the second head capacity threshold, it means that although the head capacity of the pump group meets the current operating requirements, there may be a risk of performance degradation or potential failure. The pump group needs to be maintained and adjusted to ensure its long-term stable operation. If the head capacity data is greater than the second head capacity threshold, the head capacity of the pump group is good and can easily cope with the current and possible future increased load demands.

[0046] According to an embodiment of the present invention, the flow stability data, the head capacity data and the pump group energy consumption data are processed to obtain the pump group energy efficiency index, specifically: Obtain the pump group pipeline layout characteristic data in a preset area under a preset environment; The flow stability data, head capacity data and pump group energy consumption data are combined with the pump group pipeline layout characteristic data through a preset pump group energy efficiency evaluation model to obtain a pump group energy efficiency index.

[0047] Among them, in order to comprehensively evaluate the efficiency status of the pump group, first obtain the pump group pipeline layout characteristic data in the preset area under the preset environment, including pipeline resistance data, pipeline physical characteristic data and pipeline layout structure data, and process the pump group pipeline layout characteristic data through the preset pump group energy efficiency evaluation model according to the flow stability data, head capacity data and pump group energy consumption data, and obtain the pump group energy efficiency index to reflect the energy efficiency level of the pump group under the current working conditions. By comparing the energy efficiency indexes of different pump groups, their energy efficiency differences can be intuitively evaluated, and data support can be provided for subsequent energy efficiency improvement measures; The calculation formula of the pump group energy efficiency model is: ; in, is the energy efficiency index of the pump group, They are flow stability data, head capacity data, pump unit energy consumption data and pump unit pipeline layout characteristic data. It is the preset characteristic coefficient (the characteristic coefficient is obtained by querying the preset pump group high-efficiency control database).

[0048] According to an embodiment of the present invention, the correction processing is performed according to the pump group energy efficiency index to obtain the pump group energy efficiency correction index, specifically: Obtaining and calculating the energy efficiency indexes of the pump groups in a plurality of different areas that are the same as the preset environment, and obtaining an average energy efficiency index of the pump groups; The energy efficiency index of the pump group is corrected by using an energy efficiency index correction model according to the average energy efficiency index of the pump group to obtain a pump group energy efficiency correction index.

[0049] Among them, in order to further accurately reflect the operating efficiency status of the pump group, firstly, the energy efficiency index of the pump group in multiple different areas that are the same as the preset environment is obtained and calculated to obtain the average energy efficiency index of the pump group, which reflects the general energy efficiency level of the pump group under the preset environment. Then, the energy efficiency index of the pump group is corrected by the energy efficiency index correction model to obtain the energy efficiency correction index of the pump group; The calculation formula of the energy efficiency index correction model is: ; in, is the pump group energy efficiency correction index, is the energy efficiency index of the pump group, is the average energy efficiency index of the pump group, It is the preset characteristic coefficient (the characteristic coefficient is obtained by querying the preset pump group high-efficiency control database).

[0050] According to an embodiment of the present invention, the comparison between the pump group energy efficiency correction index and a preset energy efficiency index threshold is used to determine whether the pump group energy efficiency meets the requirements, specifically: Comparing the pump group energy efficiency correction index with a preset energy efficiency index threshold, obtaining an energy efficiency index deviation rate; Comparing the energy efficiency index deviation rate with a preset index deviation rate threshold; If the energy efficiency index deviation rate is less than the index deviation rate threshold, the pump group is in a high-efficiency operation state; If the energy efficiency index deviation rate is greater than or equal to the index deviation rate threshold, the pump group is in a low-efficiency operation state.

[0051] Among them, in order to determine whether the energy efficiency of the pump group meets the requirements, the energy efficiency correction index of the pump group is compared with the preset energy efficiency index threshold to obtain the energy efficiency index deviation rate, which is compared with the preset index deviation rate threshold. If the energy efficiency index deviation rate is less than the index deviation rate threshold, it means that the energy efficiency operation state of the pump group is good and it is in a high-efficiency operation state. It can be considered that the energy efficiency level of the pump group meets or exceeds the expected standard, and no additional energy efficiency improvement measures are required. If the energy efficiency index deviation rate is greater than or equal to the index deviation rate threshold, it means that the energy efficiency operation state of the pump group is not good and it is in a low-efficiency operation state. The pump group needs to be further improved to improve its energy efficiency level.

[0052] According to an embodiment of the present invention, it also includes: Comparing the energy consumption data of the pump group with a preset energy consumption threshold, obtaining an energy consumption deviation rate; comparing the energy consumption deviation rate with a preset energy consumption deviation rate threshold; If the energy consumption deviation rate is less than the energy consumption deviation rate threshold, the energy consumption of the pump group is within the normal range; If the energy consumption deviation rate is greater than or equal to the energy consumption deviation rate threshold, the energy consumption of the pump group is abnormal.

[0053] Among them, in order to reduce the energy consumption of the pump group, the energy consumption data of the pump group is compared with the preset energy consumption threshold to obtain the energy consumption deviation rate, which is compared with the preset energy consumption deviation rate threshold. If the energy consumption deviation rate is less than the energy consumption deviation rate threshold, it means that the energy consumption of the pump group is within the normal range and meets the expected energy efficiency standards. It can be considered that the energy consumption of the pump group is properly managed and no additional energy consumption improvement measures are required. If the energy consumption deviation rate is greater than or equal to the energy consumption deviation rate threshold, it means that the energy consumption of the pump group is abnormal, and there may be problems of excessive energy consumption or low energy efficiency. Further energy consumption analysis and diagnosis of the pump group are required to find out the cause of the abnormal energy consumption.

[0054] According to an embodiment of the present invention, it also includes: Obtain water demand information of users in a preset area under a preset environment, and extract water consumption data; Comparing the water volume data with a preset water volume threshold; If the water volume data is greater than or equal to the water volume threshold, abnormal water usage data is obtained and timed to obtain abnormal water usage duration data; Comparing the abnormal water use duration data with a preset abnormal time threshold; If the abnormal water usage duration data is greater than or equal to the abnormal time threshold, there is a possibility of failure in the user-side water outlet device and an alarm message is sent.

[0055] Among them, in order to monitor in real time whether the water use at the user end is normal, the water demand information of the user end in a preset area under a preset environment is obtained, the water volume data of the water use is extracted, and compared with the preset water volume threshold. This preset water volume threshold is set according to the normal water use of the user end, historical water use data or industry standards. If the water volume data is greater than or equal to the water volume threshold, the abnormal water use data is obtained and timed, and the water use abnormality duration data is obtained. The water use abnormality duration data is compared with the preset abnormal time threshold. This preset abnormal time threshold is set according to the water use habits of the user end, the equipment maintenance cycle or the industry standard, and is used to determine whether the water use abnormality continues to the extent that attention needs to be paid. If the water use abnormality duration data is greater than or equal to the abnormal time threshold, the water outlet device at the user end may have a fault and send an alarm message, indicating that the water use abnormality at the user end has lasted for a long time, and there may be a risk of water outlet device failure. By sending an alarm message, relevant personnel can be reminded to pay attention to and deal with the abnormal water use problem at the user end in a timely manner to avoid further expansion of the fault or cause unnecessary losses.

[0056] According to an embodiment of the present invention, it also includes: Extracting water volume data, water pressure data, water time data and water period data according to the user-side water demand information; According to the water consumption data, water pressure data, water use time data and water use period data, a preset pump group high-efficiency control database is queried to obtain the corresponding pump group speed data within the pump group high-efficiency range and adjust the pump group speed.

[0057] Among them, in order to maintain the high-efficiency operation state of the pump group and meet the water use demand of the user end, water volume data, water pressure data, water time data and water period data are extracted according to the water use demand information of the user end. The water volume data is obtained by recording the water consumption of the user each time or each time period. The water pressure data is obtained by monitoring the water pressure at the user end to ensure that the water pressure is stable and meets the user's needs. The water time data records the specific time of each water use by the user. The water period data refers to the different time periods when the user habitually uses water. According to the water volume data, water pressure data, water time data and water period data, the preset pump group high-efficiency control database is queried to obtain the corresponding pump group speed data within the pump group high-efficiency range and adjust the pump group speed. The preset pump group high-efficiency control database records the pump group speeds corresponding to different water demands under the high-efficiency operation state of the pump group.
