[0060] Please refer to Figure 1 , Figure 1 This is a flow chart of a method for intelligently controlling energy conservation and consumption reduction of a pump group in some embodiments of the present application. This method for intelligently controlling energy conservation and consumption reduction of a pump group is used in a terminal device, such as a computer, a mobile phone terminal, etc. This method for intelligently controlling energy conservation and consumption reduction of a pump group includes the following steps:

[0061] S101, obtaining pump group energy efficiency parameter information within a preset area under a preset environment to extract flow stability data, head capacity data, and pump group energy consumption data;

[0062] S102, comparing the flow stability data with a preset stability threshold to determine whether the flow stability meets the requirements, and comparing the lift capacity data with a preset capacity threshold to determine whether the lift capacity meets the requirements;

[0063] 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;

[0064] S104, performing correction processing according to the pump group energy efficiency index to obtain a pump group energy efficiency correction index;

[0065] S105 , comparing the pump group energy efficiency correction index with a preset energy efficiency index threshold to determine whether the pump group energy efficiency meets the requirements.

[0066] Among them, the present application extracts flow stability data, head capacity data and pump group energy consumption data by obtaining the pump group energy efficiency parameter information in a preset area under a preset environment, and compares the flow stability data with the preset stability threshold to determine whether the flow stability meets the requirements, and compares the head capacity data with the preset capacity threshold to determine 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 a pump group energy efficiency index, and then corrects the pump group energy efficiency index according to the average energy efficiency index of multiple different areas with the same preset environment to obtain a pump group energy efficiency correction index, and compares it with the preset energy efficiency index threshold to determine 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 evaluating the energy efficiency of the pump group from multiple angles, and correcting 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.

[0067] Please refer to Figure 2 , Figure 2 This is a flow chart of a method for intelligently controlling energy conservation and consumption reduction of a pump group in some embodiments of the present application for determining whether 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 determine whether the flow stability meets the requirements, specifically:

[0068] S201, comparing the flow stability data with a preset stability threshold;

[0069] S202: If the flow stability data is less than the stability threshold, obtain flow anomaly data and count them to obtain flow anomaly frequency data;

[0070] S203, comparing the traffic anomaly number data with a preset anomaly number threshold;

[0071] S204: If the flow abnormality times data is greater than or equal to the abnormality times threshold, a pump group flow unstable alarm message is sent.

[0072] Among them, in order to judge 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. 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 failed to meet the requirements for many consecutive times and there may be serious operating problems. In this way, a pump group flow instability alarm message is sent to remind the operator or maintenance personnel to conduct timely inspection and maintenance.

[0073] Please refer to Figure 3 , Figure 3 This is a flow chart of a method for intelligently controlling energy saving and consumption reduction of a pump group in some embodiments of the present application for determining whether the lift capacity meets the requirements. According to an embodiment of the present invention, the lift capacity data is compared with a preset capacity threshold to determine whether the lift capacity meets the requirements, specifically:

[0074] S301: comparing the lift capacity data with a first lift capacity threshold and a second lift capacity threshold, respectively, where the first lift capacity threshold is smaller than the second lift capacity threshold;

[0075] S302: If the lift capacity data is less than the first lift capacity threshold, the lift capacity of the pump group is too low;

[0076] 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 requirements but needs maintenance and adjustment;

[0077] S304: If the lift capacity data is greater than the second lift capacity threshold, the lift capacity of the pump group is good.

[0078] 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 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.

[0079] Please refer to Figure 4 , Figure 4 This is a flow chart of obtaining a pump group energy efficiency index in a method for intelligently controlling energy saving and consumption reduction of a pump group in some embodiments of the present application. According to an embodiment of the present invention, the pump group energy efficiency index is obtained by processing the flow stability data, head capacity data, and pump group energy consumption data, specifically as follows:

[0080] S401, obtaining pump group pipeline layout characteristic data within a preset area under a preset environment;

[0081] 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.

[0082] To comprehensively evaluate the performance of a pump unit, the system first obtains the pump unit pipeline layout characteristic data within a preset area under a preset environment, including pipeline resistance data, pipeline physical characteristic data, and pipeline layout structure data. The system then processes the flow stability data, head capacity data, and pump unit energy consumption data in combination with the pump unit pipeline layout characteristic data through a preset pump unit energy efficiency evaluation model to obtain a pump unit energy efficiency index, which reflects the energy efficiency level of the pump unit under the current operating conditions. By comparing the energy efficiency indexes of different pump units, it is possible to intuitively assess their energy efficiency differences and provide data support for subsequent energy efficiency improvement measures.

[0083] The calculation formula of the pump group energy efficiency model is:

[0084] ;

[0085] 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).

[0086] Please refer to Figure 5 , Figure 5 This is a flow chart of obtaining a pump group energy efficiency correction index in a method for intelligent control of energy saving and consumption reduction of a pump group in some embodiments of the present application. According to an embodiment of the present invention, the correction processing is performed based on the pump group energy efficiency index to obtain the pump group energy efficiency correction index, specifically:

[0087] 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 to obtain an average energy efficiency index of the pump groups;

[0088] S502 : Correcting the energy efficiency index of the pump group using an energy efficiency index correction model according to the average energy efficiency index of the pump group to obtain a corrected energy efficiency index of the pump group.

[0089] Among them, in order to further accurately reflect the operating efficiency status of the pump group, the energy efficiency index of the pump group in multiple different areas with the same preset environment is first 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 in the preset environment. Then, the energy efficiency index of the pump group is corrected by the energy efficiency index correction model to obtain the pump group energy efficiency correction index;

[0090] The calculation formula of the energy efficiency index correction model is:

[0091] ;

[0092] 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).

[0093] 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:

[0094] Comparing the pump group energy efficiency correction index with a preset energy efficiency index threshold to obtain an energy efficiency index deviation rate;

[0095] Comparing the energy efficiency index deviation rate with a preset index deviation rate threshold;

[0096] 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;

[0097] 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.

[0098] Among them, in order to judge whether the energy efficiency of the pump group meets the requirements, the energy efficiency index deviation rate is obtained by comparing the pump group energy efficiency correction index with the preset energy efficiency index threshold, and 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.

[0099] According to an embodiment of the present invention, the further embodiment includes:

[0100] Comparing the energy consumption data of the pump group with a preset energy consumption threshold to obtain an energy consumption deviation rate;

[0101] comparing the energy consumption deviation rate with a preset energy consumption deviation rate threshold;

[0102] 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;

[0103] 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.

[0104] 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, and 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.

[0105] According to an embodiment of the present invention, the further embodiment includes:

[0106] Obtain user-side water demand information within a preset area under a preset environment and extract water consumption data;

[0107] Comparing the water consumption data with a preset water consumption threshold;

[0108] If the water consumption data is greater than or equal to the water consumption threshold, abnormal water consumption data is obtained and timed to obtain abnormal water consumption duration data;

[0109] Comparing the abnormal water use duration data with a preset abnormal time threshold;

[0110] 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.

[0111] Among them, in order to monitor whether the water use at the user end is normal in real time, the water demand information of the user end in a preset area under a preset environment is obtained, the water volume data is extracted, and compared with the preset water volume threshold. This preset water volume threshold is set according to the normal water use at 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 water use abnormality 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. It is used to determine whether the water use abnormality continues to a level that requires attention. If the water use abnormality duration data is greater than or equal to the abnormal time threshold, there is a possibility of failure in the water outlet device at the user end and an alarm message is sent, 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 water use abnormality problem at the user end in a timely manner to avoid further expansion of the fault or unnecessary losses.

[0112] According to an embodiment of the present invention, the further embodiment includes:

[0113] Extracting water volume data, water pressure data, water use time data, and water use period data based on the user-side water demand information;

[0114] 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.

[0115] Among them, in order to maintain the high-efficiency operation state of the pump group and meet the water demand of the user end at the same time, water volume data, water pressure data, water time data and water period data are extracted according to the water 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 pump group speed data corresponding to the pump group high-efficiency range and adjust the pump group speed. The preset pump group high-efficiency control database records the pump group speed corresponding to different water demands under the pump group high-efficiency operation state.

[0116] The present invention also discloses an intelligent control system for energy saving and consumption reduction of a pump group, comprising a memory and a processor. The memory comprises a program for an intelligent control method for energy saving and consumption reduction of a pump group. When the program is executed by the processor, the following steps are implemented:

[0120] Performing correction processing according to the pump group energy efficiency index to obtain a pump group energy efficiency correction index;

[0121] 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.

[0122] Among them, the present application extracts flow stability data, head capacity data and pump group energy consumption data by obtaining the pump group energy efficiency parameter information in a preset area under a preset environment, and compares the flow stability data with the preset stability threshold to determine whether the flow stability meets the requirements, and compares the head capacity data with the preset capacity threshold to determine 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 a pump group energy efficiency index, and then corrects the pump group energy efficiency index according to the average energy efficiency index of multiple different areas with the same preset environment to obtain a pump group energy efficiency correction index, and compares it with the preset energy efficiency index threshold to determine 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 evaluating the energy efficiency of the pump group from multiple angles, and correcting 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.

[0123] According to an embodiment of the present invention, the flow stability data is compared with a preset stability threshold to determine whether the flow stability meets the requirement, specifically:

[0124] Comparing the flow stability data with a preset stability threshold;

[0125] If the flow stability data is less than the stability threshold, the flow abnormality data is obtained and counted to obtain the flow abnormality number data;

[0126] Comparing the traffic anomaly count data with a preset anomaly count threshold;

[0127] If the flow abnormality times data is greater than or equal to the abnormality times threshold, the pump group flow unstable alarm information is sent.

[0128] Among them, in order to judge 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. 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 failed to meet the requirements for many consecutive times and there may be serious operating problems. In this way, a pump group flow instability alarm message is sent to remind the operator or maintenance personnel to conduct timely inspection and maintenance.

[0129] According to an embodiment of the present invention, the lift capacity data is compared with a preset capacity threshold to determine whether the lift capacity meets the requirement, specifically:

[0130] comparing the lift capacity data with a first lift capacity threshold and a second lift capacity threshold, respectively, wherein the first lift capacity threshold is smaller than the second lift capacity threshold;

[0131] If the head capacity data is less than the first head capacity threshold, the head capacity of the pump set is too low;

[0132] 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;

[0133] If the head capacity data is greater than the second head capacity threshold, the head capacity of the pump group is good.

[0134] 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 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.

[0135] 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, which is specifically:

[0136] Obtain the pump group pipeline layout characteristic data within a preset area under a preset environment;

[0137] 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.

[0138] To comprehensively evaluate the performance of a pump unit, the system first obtains the pump unit pipeline layout characteristic data within a preset area under a preset environment, including pipeline resistance data, pipeline physical characteristic data, and pipeline layout structure data. The system then processes the flow stability data, head capacity data, and pump unit energy consumption data in combination with the pump unit pipeline layout characteristic data through a preset pump unit energy efficiency evaluation model to obtain a pump unit energy efficiency index, which reflects the energy efficiency level of the pump unit under the current operating conditions. By comparing the energy efficiency indexes of different pump units, it is possible to intuitively assess their energy efficiency differences and provide data support for subsequent energy efficiency improvement measures.

[0139] The calculation formula of the pump group energy efficiency model is:

[0140] ;

[0141] 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).

[0142] 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:

[0143] 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 to obtain an average energy efficiency index of the pump groups;

[0144] 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.

[0145] Among them, in order to further accurately reflect the operating efficiency status of the pump group, the energy efficiency index of the pump group in multiple different areas with the same preset environment is first 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 in the preset environment. Then, the energy efficiency index of the pump group is corrected by the energy efficiency index correction model to obtain the pump group energy efficiency correction index;

[0146] The calculation formula of the energy efficiency index correction model is:

[0147] ;

[0148] 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).

[0149] 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:

[0150] Comparing the pump group energy efficiency correction index with a preset energy efficiency index threshold to obtain an energy efficiency index deviation rate;

[0151] Comparing the energy efficiency index deviation rate with a preset index deviation rate threshold;

[0152] 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;

[0153] 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.

[0154] Among them, in order to judge whether the energy efficiency of the pump group meets the requirements, the energy efficiency index deviation rate is obtained by comparing the pump group energy efficiency correction index with the preset energy efficiency index threshold, and 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.

[0155] According to an embodiment of the present invention, the further embodiment includes:

[0156] Comparing the energy consumption data of the pump group with a preset energy consumption threshold to obtain an energy consumption deviation rate;

[0157] comparing the energy consumption deviation rate with a preset energy consumption deviation rate threshold;

[0158] 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;

[0159] 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.

[0160] 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, and 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.

[0163] Comparing the water consumption data with a preset water consumption threshold;

[0164] If the water consumption data is greater than or equal to the water consumption threshold, abnormal water consumption data is obtained and timed to obtain abnormal water consumption duration data;

[0165] Comparing the abnormal water use duration data with a preset abnormal time threshold;

[0166] 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.

[0167] Among them, in order to monitor whether the water use at the user end is normal in real time, the water demand information of the user end in a preset area under a preset environment is obtained, the water volume data is extracted, and compared with the preset water volume threshold. This preset water volume threshold is set according to the normal water use at 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 water use abnormality 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. It is used to determine whether the water use abnormality continues to a level that requires attention. If the water use abnormality duration data is greater than or equal to the abnormal time threshold, there is a possibility of failure in the water outlet device at the user end and an alarm message is sent, 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 water use abnormality problem at the user end in a timely manner to avoid further expansion of the fault or unnecessary losses.

[0170] 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.

[0171] Among them, in order to maintain the high-efficiency operation state of the pump group and meet the water demand of the user end at the same time, water volume data, water pressure data, water time data and water period data are extracted according to the water 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 pump group speed data corresponding to the pump group high-efficiency range and adjust the pump group speed. The preset pump group high-efficiency control database records the pump group speed corresponding to different water demands under the pump group high-efficiency operation state.
