[0044] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0045] It should be noted that in the embodiments of the present application, words such as "exemplary" or "for example" are used to represent examples, illustrations or explanations. Any embodiment or design solution described as "exemplary" or "for example" in the embodiments of the present application should not be construed as being more preferred or more advantageous than other embodiments or design solutions. Rather, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific manner.

[0046] In order to facilitate a clear description of the technical solutions of the embodiments of the present application, in the embodiments of the present application, words such as "first" and "second" are used to distinguish identical or similar items with basically the same functions and roles. Those skilled in the art can understand that words such as "first" and "second" do not limit the quantity and execution order.

[0047] Before introducing the air conditioner control method provided by the present application in detail, the application scenarios and implementation environments involved in the present application will be briefly introduced.

[0048] First, the application scenarios involved in the present application will be briefly introduced.

[0049] As described in the background art, with the explosive computing power requirements of enterprises and the market, data centers are built on a large scale and in clusters. In the information technology (IT) computer rooms of the actually built and put into operation data centers, due to the peak-valley fluctuations of customer services and the differences in the rental situations of IT cabinets in the computer room, there will be differences in the operating power consumption of IT cabinets inside the computer room, resulting in high heat generation near the cabinets with high power consumption. If the air conditioner (which can also be called an air conditioner unit) in the computer room cannot perform timely air supply control, local hot spots will appear in the computer room, which will further affect the normal operation of the IT cabinets and even pose safety hazards such as fires. However, timely controlling the operation of the air conditioner to reduce local hot spots requires a large amount of electric energy. Therefore, while reducing local hot spots in the computer room, energy conservation is required.

[0050] General technologies can predict the power consumption of computer room cabinets and determine the air conditioner operation strategy based on the predicted cabinet power consumption to reduce local hot spots in the computer room. General technologies can also determine the air conditioner operation strategy for air conditioner energy conservation and computer room energy conservation to reduce local hot spots in the computer room.

[0051] However, general technologies cannot accurately control the temperature reduction of local hot spots in the computer room and will incur relatively high economic costs.

[0052] In view of the above problems, an embodiment of the present application provides an air conditioner control method. First, obtain the gas flow information in the computer room, the energy storage information of the air conditioner in the computer room, and the power supply information of the data center park to which the computer room belongs. Among them, the power supply information includes: new energy predicted power supply information and electricity price. Then, determine the air conditioner operation strategy of the air conditioner in the computer room according to the gas flow information. Next, obtain the operating power of the air conditioner in the computer room when the air conditioner operation strategy is executed. Next, determine the air conditioner power supply strategy of the air conditioner in the computer room according to the operating power, energy storage information, and power supply information. Next, control the operation of the air conditioner in the computer room according to the air conditioner operation strategy and the air conditioner power supply strategy.

[0053] As can be seen from the above, the present application can determine the air conditioner operation strategy of the air conditioner in the computer room according to the gas flow information. In this way, the air conditioner operation strategy determined based on the gas flow information in the computer room is more accurate, and can achieve precise cooling in the computer room. The present application can also determine the air conditioner power supply strategy of the air conditioner in the computer room according to the operating power of the air conditioner in the computer room when the air conditioner operation strategy is executed, the energy storage information of the air conditioner in the computer room, the new energy predicted power supply information and the electricity price of the data center park to which the computer room belongs. In this way, when determining the air conditioner power supply strategy, the present application not only considers the new energy predicted power supply information and the energy storage information, but also considers the electricity price of the data center park to which the computer room belongs, so as to reduce the economic cost of the operation of the air conditioner in the computer room.

[0054] The implementation environment of the above air conditioner control method can be the air conditioner control system provided by the embodiment of the present application.

[0055] Figure 1 The structural schematic diagram of the air conditioner control system provided by the embodiment of the present application is shown. As Figure 1 shown, the air conditioner control system includes: an air conditioner control device 101, a data storage device 102, a data acquisition device 103, and an air conditioner 104.

[0056] Among them, the air conditioner control device 101 is communicatively connected to the data storage device 102, the data acquisition device 103, and the air conditioner 104 respectively.

[0057] The data storage device 102 is communicatively connected to the data acquisition device 103.

[0058] In practical applications, the air conditioner control device 101 can be connected to any number of data storage devices 102, and the air conditioner control device 101 can be connected to any number of data acquisition devices 103. For the sake of easy understanding, Figure 1 take an example that one air conditioner control device 101 is respectively connected to one data storage device 102 and one data acquisition device 103 for illustration.

[0059] In practical applications, the air conditioner control device 101 can be connected to all the air conditioners 104 in the computer room. For the sake of easy understanding,Figure 1 Taking the example of an air conditioner control device 101 connecting two air conditioners 104 for illustration.

[0060] In the embodiment of the present application, the data acquisition device 103 is used to acquire the information of the computer room space, the energy consumption information in the computer room, and the information of the park environment status.

[0061] The data storage device 102 is used to store the data collected by the data acquisition device 103, and the data generated by the air conditioner control device 101 during the process of determining the air conditioner operation strategy and the air conditioner power supply strategy.

[0062] The air conditioner control device 101 is used to determine the air conditioner operation strategy and the air conditioner power supply strategy, and control the air conditioner 104 in the computer room based on the air conditioner operation strategy and the air conditioner power supply strategy.

[0063] Optionally, the physical device of the air conditioner control device 101 can be a server, or a terminal, or other types of electronic devices, and the embodiment of the present application does not limit this.

[0064] Optionally, the above terminal can be a device that provides voice and / or data connectivity to users, a handheld device with a wireless connection function, or other processing devices connected to a wireless modem. The wireless terminal can communicate with one or more core networks via a radio access network (RAN). The wireless terminal can be a mobile terminal, such as a mobile phone (or called a "cellular" phone) and a computer with a mobile terminal, or a portable, pocket-sized, handheld, computer-integrated or vehicle-mounted mobile device, which exchanges language and / or data with the wireless access network. For example, a mobile phone, a tablet computer, a laptop computer, a netbook, a personal digital assistant (PDA).

[0065] Optionally, the above server can be a server in a server cluster (composed of multiple servers), or a chip in the server, or a system-on-chip in the server, or can also be implemented by a virtual machine (VM) deployed on a physical machine, and the embodiment of the present application does not limit this.

[0066] Optionally, the air conditioner control device 101 and the data storage device 102 can be two independent devices, or integrated in the same device. When the air conditioner control device 101 and the data storage device 102 are integrated in the same device, the data storage device 102 can be a storage module (such as a database, etc.) of the air conditioner control device 101.

[0067] It is easy to understand that when the air conditioner control device 101 and the data storage device 102 are integrated into the same device, the communication method between the air conditioner control device 101 and the data storage device 102 is the communication between internal modules of this device. In this case, the communication process between the two is the same as that between the air conditioner control device 101 and the data storage device 102 when they are independent of each other.

[0068] For ease of understanding, this application takes the case where the air conditioner control device 101 and the data storage device 102 are independent of each other as an example for illustration.

[0069] In some embodiments, Figure 2 shows a schematic structural diagram of a control module in an air conditioner control system provided by an embodiment of this application.

[0077] The air conditioner control module is used to control the operation of the air conditioner in the computer room based on the air conditioner operation strategy and the air conditioner power supply strategy.

[0090] In the embodiments of the present application, for a communication device, the software programs stored in the memory 32 are different, so the functions implemented by the communication device are different. The functions performed by each device will be described in conjunction with the following flowcharts.

In this way, the present application can not only achieve precise cooling in the computer room, but also reduce the economic cost.

[0118] Combined with Figure 1 , the air-conditioning control device 101 can control the operation of the air conditioners 104 in the computer room according to the air-conditioning operation strategy and the air-conditioning power supply strategy.

[0119] Optionally, the air-conditioning control device can control the air-conditioning operation control switch and the air-conditioning power supply control switch to control the operation of the air conditioners in the computer room.

[0120] Among them, automation devices and terminal components such as the air-conditioning operation control switch and the air-conditioning power supply control switch are produced and configured based on the existing electrical device production technology, and the product performance will be more integrated and better overall.

[0121] In an implementable manner, the air-conditioning control device can retrieve the air-conditioning operation strategy and the air-conditioning power supply strategy, and execute the air-conditioning operation strategy and the air-conditioning power supply strategy to control the operation of the air conditioners in the computer room.

[0122] In some embodiments, the new energy predicted power supply information includes: the new energy predicted power supply power, and the energy storage information includes: the air-conditioning energy storage. Combined with Figure 4 , such as Figure 5 shown, in S404, according to the operating power, the energy storage information and the power supply information, determine the air-conditioning power supply strategy for the air conditioners in the computer room, specifically including:

[0123] S501. Determine the output power corresponding to the air-conditioning energy storage.

[0125] S502. Determine the sum of the output power corresponding to the air-conditioning energy storage and the new energy predicted power supply power as the output power of the data center park.

[0126] The new energy predicted power supply power is the power E that the data center park can provide for the operation of the air conditioner in the case of a short-term power outage. pre .

[0127] It can be understood that the output power corresponding to the air-conditioning energy storage and the new energy predicted power supply power are the powers that the data center park can provide for the operation of the air conditioner in the case of a power outage.

[0128] S503. Determine the air-conditioning power supply strategy according to the output power, the operating power and the electricity price of the data center park.

[0129] In the embodiments of the present application, the air conditioner control strategy can determine whether the air conditioner energy storage and the predicted new energy power supply can meet the air conditioner operation power supply requirements under the execution of the air conditioner operation strategy. Further, the air conditioner control device can determine the air conditioner power supply strategy in combination with the electricity price.

[0130] Therefore, the air conditioner control device can determine the output power corresponding to the air conditioner energy storage, and determine the sum of the output power corresponding to the air conditioner energy storage and the predicted new energy power supply as the output power of the data center park. The air conditioner control device can also determine the air conditioner power supply strategy according to the output power, operation power and electricity price of the data center park.

[0131] In some embodiments, in combination with Figure 5 , such as Figure 6 shown, in S503, according to the output power, operation power and electricity price of the data center park, determining the air conditioner power supply strategy specifically includes:

[0132] S601. When the output power, operation power and electricity price of the data center park meet the first preset condition, determine the air conditioner power supply strategy as: using commercial power or UPS to supply power to the air conditioners in the computer room.

[0133] The first preset condition includes: the output power of the data center park is greater than or equal to the operation power and the electricity price is less than the first electricity price threshold, or the output power of the data center park is less than the operation power and the electricity price is greater than the second electricity price threshold.

[0134] The second electricity price threshold is greater than the first electricity price threshold.

[0135] It can be understood that the output power of the data center park is greater than or equal to the operation power, that is, the predicted new energy power generation and the air conditioner energy storage can meet the air conditioner operation power supply requirements under the air conditioner operation strategy. The output power of the data center park is less than the operation power, that is, the predicted new energy power generation and the air conditioner energy storage cannot meet the air conditioner operation power supply requirements under the air conditioner operation strategy.

[0136] It can be understood that the electricity price is less than the first electricity price threshold, that is, the electricity price is a low electricity price (which can also be called the electricity price valley section). The electricity price is greater than the second electricity price threshold, that is, the electricity price is a high electricity price (which can also be called the electricity price peak section).

[0137] Therefore, when the predicted new energy power generation and the air conditioner energy storage can meet the air conditioner operation power supply requirements under the air conditioner operation strategy and the electricity price is a low electricity price, commercial power or UPS should be selected to supply power to the air conditioners in the computer room. That is, when the output power of the data center park is greater than or equal to the operation power and the electricity price is less than the first electricity price threshold, the air conditioner control device determines the air conditioner power supply strategy as: using commercial power or UPS to supply power to the air conditioners in the computer room. In this way, the economic cost can be saved.

[0138] When the power generation from new energy prediction and the air-conditioning energy storage cannot meet the power supply demand for air-conditioning operation under the air-conditioning operation strategy, and the electricity price is high, the mains power or UPS should be selected to supply power to the air-conditioning in the computer room. That is, when the output power of the data center park is less than the operating power and the electricity price is greater than the second electricity price threshold, the air-conditioning power supply strategy is determined as: using the mains power or UPS to supply power to the air-conditioning in the computer room.

[0139] S602. When the output power, operating power, and electricity price of the data center park meet the second preset condition, the air-conditioning power supply strategy is determined as: using new energy power generation and air-conditioning energy storage to supply power to the air-conditioning in the computer room.

[0140] The second preset condition includes: the output power of the data center park is greater than or equal to the operating power and the electricity price is greater than the second electricity price threshold.

[0141] When the power generation from new energy prediction and the air-conditioning energy storage can meet the power supply demand for air-conditioning operation under the air-conditioning operation strategy, and the electricity price is high, the mains power or UPS should be selected to supply power to the air-conditioning in the computer room. That is, when the output power of the data center park is greater than or equal to the operating power and the electricity price is greater than the second electricity price threshold, the air-conditioning control device determines the air-conditioning power supply strategy as: using new energy power generation and air-conditioning energy storage to supply power to the air-conditioning in the computer room. In this way, the present application can save economic costs.

[0142] Optionally, the air-conditioning control device can judge whether the new energy power generation and the air-conditioning energy storage can meet the power supply demand for air-conditioning operation under the air-conditioning operation strategy according to the output power of the data center park. When the new energy power generation and the air-conditioning energy storage can meet the power supply demand for air-conditioning operation under the air-conditioning operation strategy, the air-conditioning control device can further determine the air-conditioning power supply strategy according to the electricity price. That is, when the electricity price is at the peak period, new energy power generation and air-conditioning energy storage are preferentially selected to supply power to the air-conditioning. When the electricity price is at the valley period, the mains power or UPS is preferentially selected to supply power to the air-conditioning in the computer room. When the new energy power generation and the air-conditioning energy storage cannot meet the power supply demand for air-conditioning operation under the air-conditioning operation strategy, the air-conditioning control device can only select the mains power and UPS to supply power to the air-conditioning in the computer room.

[0143] In some embodiments, in combination with Figure 6 , such as Figure 7 shown, in S402, according to the gas flow information, determining the air-conditioning operation strategy of the air-conditioning in the computer room specifically includes:

[0144] S701. Input the gas flow information in the computer room into the first LSTM model and output the air-conditioning operation strategy.

[0145] The first LSTM model is trained according to the historical gas flow information and historical air-conditioning operation status in the computer room.

[0146] The historical gas flow information is the gas flow information in the computer room when there is a refrigeration demand in the computer room during a historical time period.

[0147] The historical air conditioner operating state is the operating state of the air conditioner in the computer room when the gas flow information in the computer room is the historical gas flow information.

[0148] In the embodiments of the present application, the air conditioner control device can input the gas flow information in the computer room into a trained first LSTM model to output an air conditioner operation strategy.

[0149] The core of the LSTM model (i.e., the LSTM network model) lies in the control through the model cell state, memory update unit, input gate, output gate, and forget gate.

[0150] Among them, the input gate unit state (which can also be called the value of the input gate) satisfies the following formula:

[0151] i C (t) = σ(W i,x ·x t +W i,h ·h t-1 +b i );

[0152] Among them, i C (t) is the output information after the input gate operation at the current time t, σ is the sigmoid function, W i,x is the input weight matrix, x t is the input data at the current time t (i.e., the data in the dataset used to train the LSTM model), h t-1 is the output hidden state of the prediction in the previous stage, W i,h is the weight coefficient matrix of the output prediction h t-1 in the previous stage of the input gate, b i is the input bias term of the input gate.

[0153] Among them, σ is used to map i C (t) to a value between 0 and 1, and the value of i C (t) is used to represent the importance of the input data. The closer i C (t) is to 1, the more important the input data is.

[0154] The candidate unit state for the above cell state update satisfies the following formula:

[0155]

[0156] Among them, tanh is the hyperbolic tangent function, W C is the weight coefficient matrix of the candidate cell unit, x tis the input data at the current time t, h t-1 is the output hidden state of the prediction result in the previous stage, b C is the input gate cell state bias term.

[0157] The above-mentioned tanh is an activation function, and its function expression satisfies the following formula:

[0158]

[0159] where e is the base of the natural logarithm, with a value approximately equal to 2.71828, and x is the input data.

[0160] The cell state of the above-mentioned memory update unit C(t) satisfies the following formula:

[0161]

[0162] where C(t) is the cell state of the memory update unit after updating the cell state, retaining important information and discarding unimportant interference information, f C (t) is the output information of the forget gate, C(t - 1) is the memory unit state information in the previous stage, i C (t) is the output information of the input gate, is the output information of the candidate unit.

[0163] The above-mentioned forget gate f C (t) has a cell state that satisfies the following formula:

[0164] f C (t) = σ(W f,x ·x t +W f,h ·h t-1 +b f );

[0165] where f C (t) is the output information after the forget gate operation at the current time t, W f,x is the input weight matrix of the forget gate, σ is the sigmoid function, h t-1 is the output hidden state of the prediction result in the previous stage, W f,h is the weight coefficient matrix of the output prediction h t-1 in the previous stage of the forget gate, b f is the cell state bias term of the forget gate.

[0166] The forget gate determines the information forgotten in the cell state at the previous moment.

[0167] The cell state formula of the above-mentioned output gate o C (t) is:

[0168] oC o(t) = σ(W o,x · x t + W o,h · h t-1 + b o );

[0169] Wherein, o C (t) is the output information after the output gate operation at the current time t (the output result of the LSTM model), σ is the sigmoid function, x t is the input data at the current time, h t-1 is the output hidden state of the prediction result in the previous stage, W o,x is the output gate weight matrix, W o,h is the weight coefficient matrix of the output prediction h t-1 in the previous stage of the output gate, b o is the output gate cell state bias term.

[0170] Exemplarily, Figure 8 shows a schematic architecture diagram of an LSTM model.

[0171] Wherein, C t-1 is the memory cell state information in the previous stage, h t-1 is the hidden state in the previous stage, x t is the input data at the current time, σ is the sigmoid function, tanh is the hyperbolic tangent function, h t is the output hidden state of the prediction result in the current stage, C t is the memory cell state in the current stage, and h is the output result of the LSTM model.

[0172] It can be known from Figure 8 that in the LSTM model, the memory cell state information C t-1 in the previous stage, the input data x t at the current time, and the hidden state h t-1 in the previous stage undergo a series of operations such as the sigmoid function, the hyperbolic tangent function, element-wise multiplication of vectors, element-wise sum, and vector concatenation, and the output hidden state h t of the prediction result in the current stage, the memory cell state C t in the current stage, and the output result h can be determined.

[0173] In some embodiments, the air conditioner control device can train the first LSTM model according to the historical gas flow information in the computer room (including: historical air flow distribution organization and historical refrigeration demand) and the historical air conditioner operation state.

[0174] That is, in the embodiments of the present application, x tIncluding: historical gas flow information (e.g., the gas flow organization distribution information A corresponding to the refrigeration demand in the computer room ds ), and the historical air conditioner operation status. W f,x is the forgetting weight coefficient matrix of the historical air conditioner operation status, historical air flow distribution organization, and historical refrigeration demand. The input information of the first LSTM model is the gas flow information in the computer room, and the output information is the air conditioner operation strategy.

[0175] Optionally, the air conditioner control device can also determine the operating power E of the air conditioners in the computer room under the air conditioner operation strategy based on the first LSTM model air .

[0176] In some embodiments, the air conditioner control device can simulate the computer room in a historical time period according to the CFD gas flow simulation model to determine the historical gas flow information in the computer room.

[0177] In some embodiments, in combination Figure 7 , such as Figure 9 shown, in S401, obtaining the new energy predicted power supply of the data center park to which the computer room belongs specifically includes:

[0178] S901. Obtain the current park environment status information of the data center park.

[0179] In the embodiments of the present application, the air conditioner control device can predict the new energy power supply according to the current park environment status information, that is, the air conditioner control device can determine the new energy predicted power supply of the data center park according to the current park environment status information. Therefore, the air conditioner control device can obtain the current park environment status information of the data center park to determine the new energy predicted power supply and further determine the air conditioner power supply strategy.

[0180] The park environment status information E Sdate includes: park environment temperature, park environment air pressure, light intensity, light duration, park environment humidity, and park wind speed.

[0181] In combination Figure 1 , the air conditioner control device 101 can obtain the current park environment status information of the data center park from the data acquisition device 103.

[0182] S902. Input the current park environment status information into the second LSTM model, and output the new energy predicted power supply of the data center park.

[0183] The second LSTM model is trained according to the historical park environment status information and historical new energy power supply.

[0184] In the embodiments of the present application, the air-conditioning control device may input the current park environmental state information into the trained second LSTM model to output the predicted power supply of new energy.

[0185] In some embodiments, the air-conditioning control device may train the second LSTM model according to the historical park environmental state information and the historical new energy power supply.

[0186] Optionally, the air-conditioning control device may train the second LSTM model according to the historical park environmental state information, the energy consumption information, and the historical new energy power supply.

[0187] The energy consumption information includes: the actual load power of the cabinets in the computer room, the operating power of the air conditioners in the computer room, the air-conditioning energy storage (which can also be referred to as the power supply capacity of the air-conditioning energy storage system), and the UPS power supply capacity.

[0188] That is, in the embodiments of the present application, x t includes: the historical park environmental state information and the historical new energy power supply. W f,x is the forgetting weight coefficient matrix of each item of information in the historical park environmental state information and the energy consumption information. The input information of the second LSTM model is the current park environmental state information, and the output information is the predicted power supply of new energy under the data state of the park environmental state information collected in real time.

[0189] In some embodiments, in combination with Figure 9 , as Figure 10 shown, in S401, obtaining the gas flow information in the computer room specifically includes:

[0190] S1001. Obtain the computer room space information of the computer room and the energy consumption information in the computer room, and construct a CFD gas flow simulation model corresponding to the computer room based on the computer room space information and the energy consumption information.

[0191] The computer room space information C Rdate of the computer room includes: the computer room space size, the cabinet position coordinates, the cabinet size, the air-conditioning unit coordinates, the air-conditioning air supply outlet position coordinates, the air-conditioning air supply temperature, the air-conditioning air return outlet position coordinates, the air-conditioning air return temperature, the air-conditioning cooling capacity and operating mode, the computer room temperature, the computer room humidity, and the computer room air pressure.

[0192] The energy consumption information E Cdate in the computer room includes: the actual load power of the cabinets in the computer room, the operating power of the air conditioners in the computer room, the air-conditioning energy storage, and the UPS power supply capacity.

[0193] In combination with Figure 1, when there is 5G network coverage, the air conditioner control device 101 can obtain the computer room space information and the energy consumption information in the computer room from the data acquisition device 103 through the 5G communication uRLLC network slice.

[0194] In some embodiments, the air conditioner control device may construct a CFD gas flow simulation model corresponding to the computer room based on the computer room space information and the energy consumption information.

[0195] Specifically, the air conditioner control device may perform grid division on the internal space of the computer room based on the computer room space information and the energy consumption information, and set physical models, boundary conditions, initial conditions, material properties, and solution parameters to construct a CFD gas flow simulation model.

[0196] S1002. Simulate the computer room based on the CFD gas flow simulation model to determine the gas flow information in the computer room.

[0197] The gas flow information includes: the air flow organization distribution A ds and the cooling requirements of different regions in the computer room.

[0198] In some embodiments, the air conditioner control device may simulate the computer room based on the CFD gas flow simulation model to determine the gas flow information in the computer room.

[0199] Specifically, the air conditioner control device may perform numerical simulation calculations based on the CFD solver in the CFD gas flow simulation model and perform visualization processing on the calculation data to determine the air flow organization distribution in the computer room and the cooling requirements of different regions in the computer room.

[0200] Optionally, the air conditioner control device may determine the air flow organization, temperature distribution, hot spot positions, etc. in the computer room based on the CFD gas flow simulation model.

[0201] Optionally, the present application may also set a normal temperature range, an abnormal temperature range, and an alarm temperature range based on the region where the data center park is located and the actual temperature of the region where the data center park is located, and set different sampling frequencies for different temperature ranges.

[0202] The schematic diagram of the correspondence between the temperature range and the sampling frequency is as Figure 11 shown.

[0203] When the temperature in the computer room is within the normal temperature range (i.e., from 0°C to temperature node T1), sample the data in the computer room based on the low-frequency heartbeat message sampling frequency.

[0204] When the temperature in the computer room is within the abnormal temperature range (i.e., from temperature node T1 to temperature node T2), increase the sampling frequency (for example, second-level, sub-second-level) to sample the data in the computer room.

[0205] When the temperature in the computer room is within the alarm temperature range (i.e., higher than the temperature node T2), the data in the computer room is sampled based on an ultra-high sampling frequency.

[0206] That is, when the temperature in the computer room is within different temperature ranges, the data in the computer room is sampled based on different sampling frequencies.

[0207] Optionally, the air-conditioning control device can set a threshold based on the time after the action instruction (i.e., the instruction corresponding to the air-conditioning operation strategy and the air-conditioning power supply strategy) is issued, and sample the data in the computer room.

[0208] Combined with Figure 1 , when the temperature in the computer room is within different temperature ranges, the air-conditioning control device 101 controls the data acquisition device 103 to sample the data in the computer room based on different sampling frequencies.

[0209] Optionally, the air-conditioning control device can also determine the operating state of the computer room according to the data in the computer room.

[0210] Combined with Figure 1 , the air-conditioning control device 101 can store the operating state of the computer room in the data storage device 102.

[0211] Optionally, when the temperature in the computer room is within the alarm temperature range, the air-conditioning control device can send an alarm signal to notify the operation and maintenance personnel to carry out maintenance.

[0212] As can be seen from the above, after controlling the operation of the air-conditioning in the computer room according to the air-conditioning operation strategy and the air-conditioning power supply strategy, the air-conditioning control device can feedback and monitor the operating state of the computer room to generate a complete work message. In this way, the operation and maintenance personnel can be notified to conduct inspections and repairs, realizing the economy and accuracy of air-conditioning operation control from the aspects of low carbon and precise control.

[0213] Optionally, after the local hot spot in the computer room dissipates and the operating state of the computer room returns to the normal operating state, the air-conditioning control device can summarize the abnormal data when the computer room fails, the issued instructions of the air-conditioning operation strategy and the air-conditioning power supply strategy, as well as the key data such as the data in the computer room (i.e., the feedback data) and the processing time, etc., to generate a fault handling message.

[0214] Combined with Figure 1 , the air-conditioning control device 101 can store the key data and the fault handling message in the data storage device 102.

[0215] Based on the above, the schematic diagram of the working process of the air-conditioning control system is as Figure 12 shown.

[0216] Step 1: The data acquisition device collects the park environmental status information, the space information in the computer room, and the energy consumption information, and transmits them to the air conditioner control device through the uRLLU network slice of 5G.

[0217] Step 2: Based on the space information and energy consumption information in the computer room, the air conditioner control device constructs a CFD gas flow simulation model corresponding to the computer room, and simulates the computer room based on the CFD gas flow simulation model to determine the air flow organization distribution in the computer room and the cooling requirements in different areas of the computer room.

[0218] Step 3: The air conditioner control device trains the first LSTM model according to the historical gas flow information and the historical air conditioner operation status, and inputs the gas flow information in the computer room into the first LSTM model to output the air conditioner operation strategy and the air conditioner operation power.

[0219] Step 4: The air conditioner control device trains the second LSTM model according to the historical park environmental status information and the historical new energy power supply, and inputs the park environmental status information into the second LSTM model to output the predicted new energy power supply of the data center park.

[0220] Step 5: Based on the predicted new energy power supply, the air conditioner operation power, the air conditioner energy storage in the energy consumption information, and the electricity price, the air conditioner control device determines the air conditioner power supply strategy for the air conditioners in the computer room.

[0221] Step 6: The air conditioner control device controls the operation of the air conditioners in the computer room according to the air conditioner operation strategy and the air conditioner power supply strategy.

[0222] Step 7: Set the correspondence between the temperature threshold and temperature range in the computer room and the sampling frequency. When the temperature in the computer room is in different temperature ranges, the air conditioner control device controls the data acquisition device to sample the data in the computer room based on different sampling frequencies, and the air conditioner control device determines the operation status of the computer room according to the data in the computer room.

[0223] Step 8: After the local hot spots in the computer room dissipate and the operation status of the computer room returns to the normal operation status, the air conditioner control device can summarize the abnormal data when the computer room fails, the issued instructions of the air conditioner operation strategy and the air conditioner power supply strategy, as well as the key data such as the data in the computer room and the processing time, etc., to generate a fault handling message.

[0224] Among them, Step 1 belongs to the data monitoring and acquisition stage, Steps 2 to 4 belong to the model training and simulation stage, and Steps 5 to 8 belong to the strategy execution stage.

[0225] Optionally, combined with Figure 2 , Figure 13 shows a schematic diagram of the working process of another air conditioner control system.

[0226] First, the communication signal detection module of the data acquisition device detects the data center network signal to determine whether the 5G wireless communication condition is met.

[0227] When the 5G wireless communication condition is met, the uRLLC network slice of 5G communication is used to transmit data. When the 5G wireless communication condition is not met, fiber optic communication is used to transmit data.

[0228] Then, the data acquisition device collects the park environmental status information, the space information in the computer room, and the energy consumption information, and transmits the data to the air conditioner control device.

[0229] Next, based on the computer room space information and energy consumption information, the air conditioner control device constructs a CFD gas flow simulation model corresponding to the computer room, and simulates the computer room based on the CFD gas flow simulation model to determine the air flow organization distribution in the computer room and the cooling requirements of different areas in the computer room.

[0230] Next, the air conditioner control device trains the first LSTM model according to the historical gas flow information and the historical air conditioner operation status, and inputs the gas flow information in the computer room into the first LSTM model to output the air conditioner operation strategy.

[0231] Next, the air conditioner control device trains the second LSTM model according to the historical park environmental status information and the historical new energy power supply, and inputs the park environmental status information into the second LSTM model to output the predicted new energy power supply of the data center park. The air conditioner control device conducts a comparative analysis on the output power corresponding to the air conditioner energy storage, the predicted new energy power supply, and the air conditioner operation power under the air conditioner operation strategy to determine whether the air conditioner energy storage and the predicted new energy power supply can meet the air conditioner operation power supply requirements under the implementation of the air conditioner operation strategy.

[0232] When the air conditioner energy storage and the predicted new energy power supply cannot meet the air conditioner operation power supply requirements under the implementation of the air conditioner operation strategy, commercial power or UPS is used to supply power to the air conditioners in the computer room.

[0233] When the air conditioner energy storage and the predicted new energy power supply can meet the air conditioner operation power supply requirements under the implementation of the air conditioner operation strategy, it is determined whether the electricity price is in the off-peak period.

[0234] When the electricity price is in the off-peak period, commercial power or UPS is used to supply power to the air conditioners in the computer room, and the new energy power supply is used to charge the air conditioner energy storage.

[0235] When the electricity price is not in the off-peak period, it is determined that the air conditioner power supply strategy is to use new energy power generation and air conditioner energy storage to supply power to the air conditioners in the computer room.

[0236] Next, the air conditioner control device controls the operation of the air conditioners in the computer room according to the air conditioner operation strategy and the air conditioner power supply strategy, and sets the correspondence between the temperature threshold and temperature range in the computer room and the sampling frequency. The air conditioner control device controls the data acquisition device to sample the data in the computer room based on different sampling frequencies, and the air conditioner control device determines the operation state of the computer room according to the data in the computer room.

[0237] Next, the air conditioner control device determines whether the local hot spots in the computer room have dissipated and whether the operation state of the computer room has returned to the normal operation state.

[0238] In the case where the local hot spots in the computer room have dissipated and the operation state of the computer room has returned to the normal operation state, the air conditioner control device can summarize the abnormal data when the computer room fails, the issued instructions of the air conditioner operation strategy and the air conditioner power supply strategy, as well as the key data such as the data in the computer room and the processing time, etc., to generate a fault handling message.

[0239] In the case where the local hot spots in the computer room have not dissipated and the operation state of the computer room has not returned to the normal operation state, it returns to the data acquisition stage, that is, the data acquisition device acquires the park environment state information, the space information in the computer room, and the energy consumption information.

[0240] As can be seen from the above, the air conditioner control method provided by the present application can monitor the hot spot distribution in the computer room and the operation state of the air conditioners in the computer room in real time to determine the local hot spots in the computer room, and accurately locate the local hot spots inside the computer room to control the operation of the air conditioners to eliminate the local hot spots in the computer room, so as to realize stable control of the operation temperature in the computer room. In this way, the operation stability of the computer room in the data center park can be improved, the power supply safety of communication equipment can be guaranteed, and the potential safety hazards of thermal runaway and even fire caused by local hot spots can be effectively avoided.

[0241] Secondly, the present application also fully considers new energy power supply, air conditioner energy storage power supply and electricity price to determine an economical and reliable air conditioner power supply strategy. The present application realizes the engineering method of low carbon and low electricity price based on demand side response, and can effectively reduce the power usage effectiveness (PUE) index and electricity price consumption of the data center operation while maintaining the stable operation of the data center.
