A large number of servers and other IT devices are deployed inside the data center, and these devices will generate a large amount of heat during operation.

Detailed implementation manners

[0057] In order to make the objectives, technical solutions and advantages of the present application clearer and more understandable, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0058] All terms used in this application (including technical and scientific terms) have the meanings commonly understood by those skilled in the art, unless otherwise defined. It should be noted that the terms used herein should be interpreted as having a meaning consistent with the context of this specification, and should not be interpreted in an idealized or overly rigid manner.

[0059] For example, terms such as "first" and "second" used in this application may be used herein to describe various elements, but these elements are not limited by these terms. These terms are only used to distinguish the first element from another element.

[0060] This application provides a water usage monitoring system for a data center, which is used to monitor the water usage of the water-cooling system in the data center. As shown in combination Figure 1 The water-cooling system includes: a makeup water loop network 20, a cooling water loop network 30, a chilled water loop network 40, and also includes a cooling water treatment subsystem 50, a chilled water treatment subsystem 55, a refrigeration device (not shown in the figure), a cooling device 65, an end device 70, a sewage pipe 80, and a water inlet loop network 10.

[0061] Among them, the inlet end of the makeup water loop network 20 is connected to the system water supply department, and the outlet end is connected to the cooling device 65.

[0062] The main function of the makeup water loop network 20 includes supplementing water source to the cooling device 65. The makeup water loop network 20 is composed of a series of pipelines and valves arranged on the pipelines. The pipeline may include an annular pipeline main body, and the water in the pipeline can circulate in the annular pipeline main body. The pipeline main body is provided with a plurality of inlet ends and a plurality of outlet ends.

[0063] The inlet end of the makeup water loop network 20 is connected to the system water supply department, and through the pipeline and valve control system, the continuity and stability of the water source are ensured. The outlet end of the makeup water loop network 20 is connected to the cooling device 65 (such as a cooling tower) to supplement water source to the cooling device 65. When it is detected that the water volume of the cooling device 65 is insufficient, water is automatically supplemented to the cooling device 65 through the makeup water loop network 20. The water supplement process is realized through the pipeline and valve control system to ensure the continuity and stability of the water source.

[0064] The cooling water loop network 30 is also composed of a series of pipelines and valves arranged on the pipelines. The pipeline may include an annular pipeline main body, and the water in the pipeline can circulate in the annular pipeline main body. The pipeline main body is provided with a plurality of cooling water inlet and outlet ends, a plurality of cooling water circulation ends, and / or cooling water treatment ends. The cooling water inlet and outlet ends on the pipeline main body of the cooling water loop network 30 are connected to the cooling device 65, and the cooling device 65 releases the heat in the cooling water to the external environment through heat exchange technology. The cooling device 65 may specifically be one or more devices such as a cooling tower and / or an air-cooled radiator, etc.

[0065] The cooling water circulation end of the cooling water loop network 30 is connected to a refrigeration device (not shown in the figure), and the chilled water circulation end of the chilled water loop network 40 is also connected to the refrigeration device. The refrigeration device is, for example, a chiller. The refrigeration device provides circulating refrigeration for the chilled water in the chilled water loop network 40. There can be multiple refrigeration devices, and each refrigeration device is respectively connected to the cooling water loop network 30 and the chilled water loop network 40.

[0066] The chilled water loop network 40 is also composed of a series of pipes and valves arranged on the pipes. The pipes can include an annular pipe body, and the chilled water in the pipes can circulate in the annular pipe body. The pipe body is provided with multiple chilled water makeup ends, multiple chilled water circulation ends, multiple end device connection ends, and / or chilled water treatment ends.

[0067] The chilled water makeup end of the chilled water loop network 40 is communicated with the system water supply part, the end device connection end of the chilled water loop network 40 is communicated with the end device 70, and the chilled water in the chilled water loop network 40 flows through the end device 70 to absorb heat generated in, for example, the computer room. The end device 70 is, for example, an air-conditioning terminal. The chilled water circulation end of the chilled water loop network 40 is connected to the refrigeration device, and the chilled water exchanges heat with the cooling water in the refrigeration device and then returns to the chilled water loop network 40 again to form a continuous cycle.

[0068] In the water-cooled system of this application, the loop network structures of the cooling water loop network 30, the chilled water loop network 40, and the makeup water loop network 20 all adopt an annular design to ensure the continuous circulation and efficient utilization of the system. Each loop network structure is composed of pipes, valves, pumps, and key equipment, and realizes the efficient heat dissipation and energy conservation of the data center through synergy; in addition, the makeup water loop network 20 is used to supply water sources to the cooling water loop network 30 and the chilled water loop network 40, which can improve the stability of water source replenishment; and then the refrigeration device is used to exchange heat between the water in the cooling water loop network 30 and the chilled water loop network 40, further improving the utilization efficiency of the water source.

[0069] In one embodiment, as shown in Figure 1 the water-cooled system further includes a cooling water treatment subsystem 50 and a chilled water treatment subsystem 55. The water treatment end of the cooling water treatment subsystem 50 is communicated with the cooling water treatment end of the cooling water loop network 30 for treating the water quality of the cooling water in the cooling water loop network 30; the water treatment end of the chilled water treatment subsystem 55 is communicated with the chilled water treatment end of the chilled water loop network 40 for treating the water quality of the chilled water in the chilled water loop network 40.

[0070] The cooling water treatment subsystem 50 includes a cooling water treatment pipeline 53, water treatment equipment disposed on the cooling water treatment pipeline 53, and a sewage pipe 80. The cooling water treatment pipeline 53 is connected to the cooling water loop network 30. After a part of the cooling water is treated by the water treatment equipment on the cooling water treatment pipeline 53, it returns to the cooling water loop network 30. The water treatment equipment is used for water quality treatment and may include one or more of a chemical dosing treatment device 51 and / or a filtration treatment device 52, etc. The sewage / waste water after being treated by one or more water treatment devices is discharged through the sewage pipe 80.

[0071] Optionally, there may be multiple cooling water treatment subsystems 50, and each cooling water treatment subsystem 50 is respectively connected to the cooling water treatment end of the cooling water loop network 30. The water treatment equipment in each cooling water treatment subsystem 50 is not necessarily the same. For example, Figure 1 as shown, it includes two cooling water treatment subsystems 50. A chemical dosing treatment device 51 is arranged on one of the cooling water subsystems; two filtration treatment devices 52 are arranged on the other cooling water subsystem.

[0072] The chilled water treatment subsystem 55 includes a chilled water treatment pipeline 56, water treatment equipment disposed on the chilled water treatment pipeline 56, and a sewage pipe 80. The chilled water treatment pipeline 56 is connected to the chilled water loop network 40. After a part of the chilled water is treated by the water treatment equipment on the chilled water treatment pipeline 56, it returns to the chilled water loop network 40. The water treatment equipment is used for water quality treatment and may also include one or more of a chemical dosing treatment device 51 and / or a filtration treatment device 52, etc. The sewage / waste water after being treated by one or more water treatment devices is discharged through the sewage pipe 80.

[0073] Optionally, there may be multiple chilled water treatment subsystems 55, and each chilled water treatment subsystem 55 is respectively connected to the chilled water treatment end of the chilled water loop network 40. The water treatment equipment in each chilled water treatment subsystem 55 is not necessarily the same. For example, Figure 1 as shown in, the water treatment equipment arranged in one of the chilled water treatment subsystems 55 is a chemical dosing treatment device 51.

[0074] By providing multiple cooling water treatment subsystems 50 and multiple chilled water treatment subsystems 55, the water quality in the cooling water loop network 30 and the chilled water loop network 40 can be independently treated as needed, improving the flexibility of water quality treatment; and by providing multiple cooling water treatment subsystems 50 and multiple chilled water treatment subsystems 55, it can prevent other cooling water treatment subsystems 50 and chilled water treatment subsystems 55 from working independently when some of the cooling water treatment subsystems 50 or chilled water treatment subsystems 55 fail, so as to ensure the stability of water quality treatment.

[0075] In one embodiment, the system water supply section includes a water inlet ring network 10. The first water outlet end of the water inlet ring network 10 is connected to a production water inlet pipe 24. A production water tank 22 and a pump 21 are sequentially arranged on the production water inlet pipe 24. Optionally, a non-negative pressure pipe 25 is also connected to the production water inlet pipe 24. As Figure 1 shown, the non-negative pressure pipe 25 communicates with the production water inlet pipe 24 and a make-up water ring network 20. A non-negative pressure make-up water device 23 is arranged on the non-negative pressure pipe 25, so that the water flowing out of the water inlet ring network 10 can directly flow to the make-up water ring network 20 through the non-negative pressure make-up water device 23. The water inlet ring network 10 is communicated with the make-up water ring network 20 through the production water inlet pipe 24 and the non-negative pressure pipe 25.

[0076] The second water outlet end of the water inlet ring network 10 is connected to the chilled water make-up end of a chilled water ring network 40 through a chilled water inlet pipe 26.

[0077] In this embodiment, the water inlet ring network 10 is also composed of a series of pipes and valves arranged on the pipes. The pipes may include an annular pipe body, and the water in the pipes can circulate in the annular pipe body. The water inlet end of the water inlet ring network 10 can be connected to the municipal water supply of the park. The water inlet end may include multiple ones to improve the stability of water inlet. Production water is stored in the production water tank 22, and the water in the production water tank 22 can flow to the water inlet end of the make-up water ring network 20 and the chilled water make-up end of the chilled water ring network 40.

[0078] For example Figure 1 as shown in Figure 1 there are two production water tanks 22. One of the production water tanks 22 is only used to supply water to the make-up water ring network 20 through the production water inlet pipe 24, and the other production water tank 22 is not only used to supply water to the make-up water ring network 20 through the production water inlet pipe 24, but also supplies water to the chilled water ring network 40 through a chilled water quick make-up pipe 27. As

[0079] Specifically, one end of the chilled water quick replenishment pipeline 27 is connected to the pipeline section downstream of the production water inlet pipeline 24 in the production water tank 22, and the other end can be directly connected to the chilled water replenishment end or connected to the chilled water inlet pipeline 26 to achieve connection with the chilled water loop network 40 through the chilled water inlet pipeline 26. For example, the chilled water quick replenishment pipeline 27 extending from the production water inlet pipeline 24 can form multiple branches, one of which is directly connected to the chilled water replenishment end, and the other is communicated with the chilled water inlet pipeline 26. In this way, the water from the chilled water quick replenishment pipeline 27 can supply water to the chilled water loop network 40 independently or supply water to the chilled water loop network 40 after merging with the production water inlet pipeline 24. Among them, control valves can be provided in the pipeline section before the branch of the production water inlet pipeline 24, and corresponding control valves are provided in the pipeline section after each branch, so as to control the water supply mode to the chilled water loop network 40 through the chilled water quick replenishment pipeline 27.

[0080] In one embodiment, a soft water control valve 41 and a soft water device 42 are provided on the chilled water inlet pipeline 26, and the soft water device 42 is communicated with the chilled water inlet pipeline 26 in parallel with the soft water control valve 41.

[0081] Among them, in the normal state, the soft water control valve 41 is in a normally closed state, so that the water flowing into the chilled water loop network 40 needs to be treated by the soft water device 42, improving the quality of the water entering the chilled water loop network 40. When there is a water supply shortage, the soft water control valve 41 is directly opened, so that the water in the water inlet loop network 10 can directly flow into the chilled water loop network 40. Among them, a constant pressure water replenishment device 43 is also arranged downstream of the soft water control valve 41 and the soft water device 42, so that the water flowing into the chilled water loop network 40 enters the chilled water loop network 40 through the constant pressure water replenishment device 43 after passing through the soft water control valve 41 and / or the soft water device 42, improving the stability of the water entering the chilled water loop network 40.

[0082] In addition, the water use monitoring system is also provided with a humidification variable frequency water replenishment pipeline 28, which is connected to the chilled water inlet pipeline 26 and is specifically arranged between the downstream of the soft water control valve 41 and the upstream of the constant pressure water replenishment device 43. A humidification variable frequency water replenishment device 44 and a variable frequency water replenishment control valve 45 are provided on the humidification variable frequency water replenishment pipeline 28. When the variable frequency water replenishment control valve 45 is opened, the water in the water inlet loop network 10 can flow through the chilled water inlet pipeline 26 to the humidification variable frequency water replenishment pipeline 28; when the variable frequency water replenishment control valve 45 is closed, the water in the chilled water inlet pipeline 26 does not pass through the humidification variable frequency water replenishment pipeline 28.

[0083] Specifically, in the normal state, the chilled water quick replenishment pipeline 27 is in a disconnected state, and water is supplied to the chilled water loop network 40 through the chilled water inlet pipeline 26. When the water demand of the chilled water loop network 40 exceeds the preset required water consumption, the chilled water quick replenishment pipeline 27 and the chilled water inlet pipeline 26 are simultaneously activated, so that water can be supplied to the chilled water loop network 40 through the chilled water quick replenishment pipeline 27 and the chilled water inlet pipeline 26 at the same time, so as to ensure that the water in the chilled water loop network 40 meets the water demand. Among them, the on-off state of the chilled water quick replenishment pipeline 27 can be controlled by a quick replenishment control valve 46 arranged on the chilled water quick replenishment pipeline 27.

The water consumption of the terminal device can be obtained from the data measured by the nineteenth water flow rate monitoring devices 60-19.

[0093] In one embodiment, a water consumption monitoring method for a data center is provided, and this method is applied to the water-cooled system of the data center in any embodiment of the present application. As Figure 2 shown, this includes:

[0094] Step 210, obtain the water flow rate data measured by each water flow rate monitoring device arranged at the corresponding positions of the water inlet end and the water outlet end of the makeup water loop network, the cooling water inlet and outlet ends of the cooling water loop network, and the chilled water makeup end of the chilled water loop network.

[0095] In this embodiment, the corresponding positions of the relevant ports of each ring network can be appropriate positions on the pipelines connected to the relevant ports. The water flow monitoring devices on each ring network and the corresponding nodes such as the relevant pipelines can measure the flowing water flow in real time. The water flow data can be the real-time cumulative water consumption flow and / or the real-time water flow. Based on the cumulative water consumption flow and / or the real-time water flow, combined with the collected duration, the water consumption within different durations can be calculated.

[0096] Specifically, a corresponding water usage cycle is preset. The water usage cycle can be any appropriate duration such as 12 hours, one day, two days, one week, one month, one quarter, one year, etc. Through the real-time collected water flow data, the water consumption of each node under the corresponding current water usage cycle or each historical water usage cycle can be calculated.

[0097] Furthermore, the water flow data measured by each water flow monitoring device arranged at the corresponding positions of the cooling water treatment end and the chilled water treatment end is also obtained.

[0098] For example, corresponding water flow monitoring devices are provided on the pipelines corresponding to each outlet end (including the first outlet end and the second outlet end) of the inlet ring network, each inlet end, each outlet end of the makeup water ring network, the cooling water ring network, and the chilled water ring network, each circulating water end of the cooling water ring network and the chilled water ring network, and the sewage discharge ends of the cooling water treatment subsystem and the chilled water treatment subsystem. The water flow data can include the real-time water consumption flow or the real-time water flow of the above-mentioned corresponding ports.

[0099] Such as Figure 1 shown, the node can be the above-mentioned production inlet pipeline 24, non-negative pressure pipeline 25, chilled water inlet pipeline 26, chilled water quick makeup pipeline 27, cooling water treatment pipeline 53, chilled water treatment pipeline 56, sewage discharge pipe 80, or can also be the pipeline corresponding to each inlet end of the makeup water ring network 20, the pipeline corresponding to the cooling water inlet and outlet ends of the cooling water ring network 30, and the pipeline corresponding to the connection end of the end equipment of the chilled water ring network 40. The corresponding water flow data can be obtained by acquiring the measured values of the water flow monitoring devices on the corresponding nodes.

[0100] Among them, the sum of the water consumption of each outlet end of the inlet ring network is the total water consumption of the data center. That is, the sum of the water consumption measured by the above-mentioned first water flow monitoring device 60-1 and the fifth water flow monitoring device 60-5 is the total water consumption.

[0101] The total water consumption on the cooling side is the sum of the water consumption at each water inlet end of the cooling water loop network, for example, the water consumption calculated from the water flow data of the two production water tanks and the non-negative pressure pipeline as described above. Optionally, it can be the sum of the water consumption measured by each of the above-mentioned second water flow monitoring devices 60-2 (or the first water flow monitoring device 60-1) and the third water flow monitoring device 60-3, minus the water consumption measured by the fourth water flow monitoring device 60-4, and the result is the total water consumption on the cooling side.

[0102] The total water consumption on the refrigeration side is the sum of the water consumption at each water inlet end of the chilled water loop network, for example, the sum of the water consumption in each of the above-mentioned chilled water inlet pipelines 26 and the chilled water quick replenishment pipeline 27. That is, the sum of the water consumption measured by the fifth flow monitoring device 60-5 and the fourth flow monitoring device 60-4.

[0103] The cooling water discharge amount is the sum of the water consumption through each sewage pipe of the cooling water treatment subsystem, that is, the sum of the water consumption measured by each of the ninth flow monitoring devices 60-9; the chilled water discharge amount is the sum of the water consumption through each sewage pipe of the chilled water treatment subsystem, that is, the sum of the water consumption measured by each of the seventeenth flow monitoring devices 60-17.

[0104] Step 220: Calculate the total production water consumption of the data center in a target period based on the water flow data.

[0105] In this embodiment, taking the water flow data as the real-time cumulative water consumption as an example, the electronic device can extract the water consumption of each node at the starting moment of a target period and the water consumption of each node at the ending moment of the target period, calculate the difference in water consumption of the same node at the two moments, and then calculate the water consumption of the corresponding node in the target period. This node includes each water outlet end of the above-mentioned water inlet loop network, for example, includes the above-mentioned first water outlet end and the second water outlet end.

[0106] After obtaining the water consumption of each water outlet end of the water inlet loop network in a target period, add up the water consumption of each water outlet end, and the result is the total production water consumption of the data center in the target period.

[0107] Step 230: Obtain the total power consumption of the data center in the target period.

[0108] The total power consumption of the data center can be directly obtained or indirectly calculated from the relevant power monitoring system.

[0109] Step 240: Calculate the water utilization efficiency in the data based on the total production water consumption and the total power consumption.

[0110] Water utilization efficiency is used to measure the amount of water required for each degree of electricity consumed in a data center. Specifically, water utilization efficiency is the quotient of the total water consumption for production and the total electricity consumption, that is, water utilization efficiency = total water consumption for production / total electricity consumption. The lower the water utilization efficiency, the more efficient the water use in the data center.

[0111] Step 250: Determine whether there is abnormal water use in the data center in the target period based on the water utilization efficiency.

[0112] Among them, the electronic device also sets a water utilization efficiency threshold or a water utilization efficiency threshold range, which is a reference value or a reference value range for measuring whether there is abnormal water use in the data center.

[0113] Specifically, the water utilization efficiency threshold or the water utilization efficiency threshold range is a preset fixed value, or a value that adaptively changes dynamically according to the actual production situation. For example, the electronic device sets the water utilization efficiency threshold or the water utilization efficiency threshold range in different periods according to the historical water consumption and electricity consumption of the data center, so that the set water utilization efficiency threshold or the water utilization efficiency threshold range matches the actual state.

[0114] When the calculated water utilization efficiency is within the preset water utilization efficiency threshold range, or less than the preset water utilization efficiency threshold, it indicates that the water use status in the target period is normal; otherwise, it is determined that the water use status is abnormal.

[0115] In the water use monitoring method of the data center in this application, based on the above-mentioned water cooling system, the water consumption of each node in the target period can be calculated, and then based on this water consumption, the total water consumption for production in the target period can be calculated. Combining with the total electricity consumption of the data center, the water utilization efficiency of the data center can be calculated. Based on this water utilization efficiency, it can be determined whether the data center is in a normal water use state in the target period.

[0116] In one embodiment, the water flow data includes the cooling makeup water flow through the production inlet pipe, the non-negative pressure makeup water flow through the non-negative pressure pipe, the cooling water discharge volume through the cooling water treatment subsystem, and also includes the chilled water discharge volume through the chilled water treatment subsystem, and the chilled water side water consumption of each pipe (including the chilled water inlet pipe 26 and the chilled water quick makeup pipe 27) corresponding to the chilled water makeup end of the chilled water ring network. The total chilled water side water consumption can be the sum of the chilled water side water consumption of each pipe corresponding to the chilled water makeup end of the chilled water ring network.

[0117] Such as Figure 1As shown in the figure, the total water consumption for the chilled water measurement can be the sum of the constant pressure makeup water volume flowing through the pipelines where the two constant pressure makeup water devices 43 are located and the chilled water fast makeup volume flowing through the chilled water fast makeup pipeline 27. The specific water volume or water flow rate mentioned above can be calculated directly or indirectly through the water flow monitoring devices arranged on the corresponding pipelines. It can be calculated from the water consumption measured by one or more of the above-mentioned fifth flow monitoring device 60-5, fourth flow monitoring device 60-4, eleventh flow monitoring device 60-11, twelfth flow monitoring device 60-12, thirteenth flow monitoring device 60-13, fourteenth flow monitoring device 60-14, fifteenth flow monitoring device 60-15, etc. And the data measured by these flow monitoring devices can be used to verify whether there are abnormal conditions such as water leakage in the corresponding pipelines.

[0118] Among them, the sum of the cooling makeup water flow rate through the production inlet pipeline and the non-negative pressure makeup water flow rate through the non-negative pressure pipeline is the water flow rate flowing into the cooling water ring network from each inlet end, that is, the total cooling water consumption mentioned above. The cooling water discharge volume of the cooling water treatment subsystem is the sum of the water consumption through each discharge end of the cooling water treatment subsystem.

[0119] The above method further includes: calculating the evaporation flow rate of the cooling equipment in the target period based on the cooling makeup water flow rate, non-negative pressure makeup water flow rate, and cooling water discharge volume; determining whether there is abnormal water use in the data center in the target period based on the evaporation flow rate.

[0120] In this embodiment, the evaporation flow rate is the difference between the total cooling water consumption and the cooling water discharge volume. That is, evaporation flow rate = total cooling water consumption - cooling water discharge volume = (cooling makeup water flow rate + non-negative pressure makeup water flow rate) - cooling water discharge volume. The cooling makeup water flow rate can be obtained from the data measured by the second flow monitoring device 60-2 and the fourth flow monitoring device 60-2, and the non-negative pressure makeup water flow rate can be obtained from the data measured by the third flow monitoring device 60-3.

[0121] Based on the total cooling water consumption and the cooling water discharge volume at the start time and end time in the target period, the total cooling water consumption in the corresponding target period and the cooling water discharge volume in the target period can be obtained, and further the evaporation flow rate in the target period can be calculated.

[0122] Similarly, the electronic device can preset the normal range or evaporation threshold of the evaporation flow rate, and this normal range or evaporation threshold can be determined based on relevant historical data (such as the average evaporation flow rate and its fluctuation range in the past few months or years). The normal range or evaporation threshold can be updated regularly to ensure its accuracy and reliability.

[0123] After obtaining the evaporation flow rate of the target period, compare it with a preset normal range or evaporation threshold. If the evaporation flow rate exceeds the normal range or reaches / exceeds the threshold, trigger an alarm mechanism to prompt the data center management that there may be abnormal water usage.

[0124] In one embodiment, the above method further includes: calculating the chilled water leakage volume on the chilled side in the target period based on the chilled water blowdown volume and the chilled water side water consumption; determining whether there is abnormal water usage on the chilled side in the target period based on the chilled water leakage volume.

[0125] The chilled water leakage volume is used to evaluate the leakage situation, pressure fluctuation, etc. on the chilled side. Specifically, the chilled water leakage volume = total chilled water side water consumption - chilled water blowdown volume. After obtaining the chilled water leakage volume of the target period, compare it with a preset leakage threshold. If the evaporation flow rate exceeds the leakage threshold, trigger an alarm mechanism to prompt the data center management that there may be abnormal water usage on the chilled side.

[0126] When detecting abnormal water usage, the management should immediately check the cooling system to find possible leakage points, blockages, or efficiency degradation problems. Take corresponding maintenance measures according to the inspection results, such as replacing damaged components, cleaning blocked pipes, or adjusting system parameters, etc.

[0127] By implementing the above method, the data center can achieve precise monitoring and abnormal detection of the evaporation flow rate of the cooling system, so as to timely discover and solve potential problems, and ensure the stable operation and high energy consumption of the data center.

[0128] In one embodiment, the above method further includes: calculating the total blowdown volume based on the cooling water blowdown volume and the chilled water blowdown volume; calculating the proportion of cooling water blowdown through the total cooling water side water consumption and the cooling water blowdown volume.

[0129] Among them, the total blowdown volume = cooling water blowdown volume + chilled water blowdown volume, which is used to evaluate the water quality situation of the data center. The proportion of cooling water blowdown = cooling water blowdown volume / total cooling water side water consumption, which is used to evaluate the percentage of the water volume used for blowdown on the cooling water side in the total cooling water side water consumption.

[0130] In one embodiment, the above method further includes the process of alarming for the water flow data not changing for a long time and over - quantity alarm. This process can be executed after step 210 above, for example, specifically after step 250, as Figure 3 shown, this process includes:

[0131] Step 310, calculate the change value of the water flow data over a preset time period.

[0132] In this embodiment, the preset duration can be any suitable duration set arbitrarily, and this preset duration is less than the change period. For example, the preset duration can be any suitable duration such as 10 minutes, 30 minutes, 1 hour, 2 hours, etc. The change value within the preset duration can be calculated by the difference between the water flow data at the end moment of the preset duration and the water flow value at the start moment of the preset duration.

[0133] For example, the preset duration is 1 hour, and the electronic device extracts the water flow data at a certain node at 12:00 and 13:00 respectively, which are 100 cubic meters and 102 cubic meters. Then the water flow change value of this node within the preset duration is 2 cubic meters.

[0134] Step 320, detect whether the change value exceeds the corresponding preset first change threshold. When it does not exceed the change threshold, generate the first warning information indicating that the water flow monitoring device is abnormal.

[0135] In this embodiment, the first change threshold is a critical threshold for measuring whether the water flow monitoring device is normal. The first change thresholds corresponding to the water flow monitoring devices at different nodes are different. The electronic device can set the first change threshold according to the change values in the historical duration of each node and update the first change threshold regularly.

[0136] If the change value does not exceed the corresponding first change threshold, it means that the water flow monitoring device has not changed for a long time. At this time, the electronic device generates the first warning information, and the first warning information can be sent to the management personnel of the data center by means of email, text message or system interface, etc. for prompt.

[0137] Step 330, obtain the reference water use range corresponding to the total production water use.

[0138] In this application, the execution order between step 310 to step 320 and step 330 to step 340 can be not limited. For example, step 310 to step 320 and step 330 to step 340 can be executed in parallel.

[0139] Furthermore, the electronic device also sets a reference water use range, which represents the normal total production water use range of the data center within a target period. Similarly, this reference water use range can be any suitable fixed range set in advance, or a range set according to the total production water use in the historical target period. For example, the reference water use range can be calculated according to the total production water use in the normal state in the recent N historical target periods.

[0140] Specifically, taking the total production water consumption in the normal state under the N historical target cycles as the corresponding data set, calculate the upper quartile Q3 and the lower quartile Q1 corresponding to this data set, and calculate the upper limit value and the lower limit value of the reference water consumption interval based on the upper quartile Q3 and the lower quartile Q1, so as to determine the reference water consumption interval.

[0141] For the numerical sizes of the data in the data set, sort them in ascending order, select the numerical point at the 1 / 4 position in the sorting as the lower quartile Q1, and take the numerical point at the 3 / 4 position in the sorting as the upper quartile Q3, where Q3 > Q1.

[0142] For example, the upper limit value P3 = Q3 + K3; the lower limit value P1 = Q1 - K1, where K1 and K3 are appropriate deviation amounts. This deviation amount can be a fixed value or a value determined according to any one or more parameters of the current production environment and Q1, Q3. For example, K1 = k1×(Q3 - Q1); K3 = k3×(Q3 - Q1), where k1 and k3 can be coefficients adaptively adjusted according to the current production environment. The production environment includes the workload of the data center and external environment information, and the external environment information includes one or more of outdoor dry-bulb temperature, wet-bulb temperature, rainfall conditions, etc. For example, based on the production environment, it is calculated that k1 = 1.1 and k2 = 1.3.

[0143] Step 340, detect whether the total production water consumption is within the reference water consumption interval. When it is not within the reference water consumption interval, generate a second warning message for abnormal water consumption in the data center.

[0144] It can be compared whether the total production water consumption is greater than or equal to the above lower limit value P1 and less than or equal to the above upper limit value P3. If so, it means it is within the reference water consumption interval, otherwise it is not within the reference water consumption interval.

[0145] When it is not within the reference water consumption interval, generate a second warning message for abnormal water consumption. Similarly, the first warning message can be sent to the management personnel of the data center by means of email, text message or system interface, etc. for reminder.

[0146] If the total production water consumption is less than the lower limit value of the reference water consumption interval, it means that the total production water consumption in the target cycle is too little, and the second warning message contains the information that the total production water consumption is too little; if the total production water consumption is greater than the upper limit value, it means that the total production water consumption in the target cycle is too much, and the second warning message contains the information that the total production water consumption is too much.

[0147] When the water consumption is not within the reference water consumption range, it is possible to further detect which one or more nodes have abnormal water consumption. Specifically, the water consumption data of each node can be compared with the historical water consumption data of the same node or the water consumption threshold of the same node to further locate the abnormal water consumption nodes.

[0148] The water consumption monitoring method for the data center in this application can monitor the water consumption of the data center in real time and generate alarm information in a timely manner when the water consumption is abnormal, which helps the management personnel of the data center to detect and handle abnormal water use equipment or excessive water use in a timely manner, thus ensuring the efficient operation of the data center and the reasonable utilization of resources.

[0149] In one embodiment, the above method further includes: regarding the water flow monitoring device that measures water flow data not exceeding the change threshold based on the first alarm information as an abnormal device; obtaining the historical water consumption data corresponding to the abnormal device, and calculating water consumption correction data based on the historical water consumption data; correcting the water flow data of the abnormal device based on the water consumption correction data.

[0150] For the abnormal device, the true water consumption data (i.e., water consumption correction data) of the node corresponding to the abnormal device can be inferred from the historical water consumption data of the abnormal device, and this true water consumption data is used as the water consumption.

[0151] The historical water consumption data can be the water flow data measured by the abnormal device within multiple past time periods. The historical water consumption data can be retrieved from a database or cloud storage to ensure the integrity and accuracy of the data. For each abnormal device, the system will collect a long enough sequence of historical water consumption data for subsequent analysis and calculation. Based on this historical water consumption data, the electronic device can calculate water consumption correction data based on a specific algorithm or model. These water consumption correction data are intended to reflect the water flow that should be in normal conditions, so as to correct the current abnormal measurement data.

[0152] Among them, the algorithm or model can include one or a combination of mathematical statistical methods (such as moving average, exponential smoothing, etc.), machine learning models (such as time series prediction models), or physical principle-based models (such as water flow dynamics models), etc. The calculation process can further consider the production environment where the historical water consumption data is located, so that the calculated water consumption correction data is more in line with the actual situation.

[0153] The calculated water consumption correction data is used to correct the water flow data of the abnormal device. When the repair or replacement of the abnormal device is completed, the water consumption correction data is used as the water flow data of the repaired or replaced abnormal device, thus avoiding false alarms and missed alarms caused by equipment failures or data errors.

[0154] In one embodiment, historical water use data corresponding to the abnormal device is obtained, and water use correction data is calculated based on the historical water use data, including: determining the abnormal time when the abnormal device becomes abnormal based on the water flow data of the abnormal device in the target period; obtaining external environmental information in a correction time interval, the start time of the correction time interval is the abnormal time, and the end time is the correction time for correcting the data of the abnormal device; obtaining the historical water use data of the abnormal device in a reference historical time interval corresponding to the correction time interval; and calculating the water use correction data based on the external environmental information and the historical water use data.

[0155] The abnormal moment is the starting moment when the abnormal device becomes abnormal. The electronic device can determine the moment when the abnormal change first occurs based on the water flow data collected by the abnormal device at each moment in the target cycle and the change trend reflected by the water flow data, and use this moment as the abnormal moment. The moment of abnormal change includes the moment when the change is too drastic or too slow. For example, when the abnormal device is damaged or powered off, its water flow data has not changed since a certain moment, which means that the starting moment when there is no change is the abnormal moment; or if it is detected that the water flow data has increased significantly since a certain moment and has maintained the trend of increasing significantly, which means that the moment when the significant increase begins is the abnormal moment.

[0156] After knowing the abnormal time, the workload and external environment information of the node corresponding to the abnormal device in the data center corresponding to the correction time interval can be obtained, and the historical water consumption data of the node corresponding to the abnormal device in the reference historical interval corresponding to the correction time interval can be obtained. The starting time of the correction time interval is the abnormal time, and the ending time is the correction time for correcting the abnormal device. For example, if the correction of the abnormal device is completed at a certain time, then this time is the correction time. The correction process includes the recovery process or replacement process of the abnormal device.

[0157] By obtaining the historical water consumption data in the reference historical duration interval, the reference water consumption of the node corresponding to the abnormal device in the corrected duration interval can be calculated. The reference water consumption is adjusted by combining the workload and external environment information in the corrected duration interval with the workload and external environment information in the reference historical duration interval to obtain the adjusted reference water consumption, and the water consumption correction data is calculated based on the adjusted reference water consumption.

[0158] Taking the abnormal device as a water meter as an example, the water flow data is the accumulated water consumption, and the water consumption correction data can be the sum of the water flow data of the abnormal device at the abnormal moment and the adjusted reference water consumption.

[0159] By using historical water consumption data within a reference historical duration range and external environmental information of the data center, the accuracy of correcting water flow data of abnormal devices can be improved.
