Description

Technical Field

[0001] The present invention relates to the technical field of computer room space energy consumption prediction, and in particular to a computer room space energy consumption prediction method based on a long short-term memory network. Background Art

[0002] Traditional data center energy management relies primarily on sensor-based linear control algorithms and static prediction models. These methods have significant limitations when dealing with complex and changing computer room environments (such as dynamic load changes, non-uniform temperature distribution, and sudden equipment failures). Specifically,

[0003] 1. Data sample limitations:

[0004] Real computer room operating data usually only covers routine operating conditions within a safe range, and lacks data on abnormal scenarios (such as air conditioning failures and extreme high temperatures). This results in a single model training sample and makes it difficult to predict energy consumption and risks in extreme situations.

[0005] Neural networks trained on real data are prone to overfitting, lack generalization capabilities, and are unable to adapt to complex nonlinear dynamic systems in reality.

[0006] 2. Static nature and experience dependence of control strategy:

[0007] Traditional methods are mostly based on fixed rules (such as setting a constant temperature threshold) or manual experience to adjust air conditioning parameters. They lack dynamic optimization capabilities and find it difficult to balance energy efficiency (PUE optimization) and safety (overheating risk avoidance) in real time.

[0008] Existing algorithms have a weak ability to capture time series features and cannot effectively model the long-term dependence between energy consumption and temperature changes in computer rooms.

[0009] 3. Lack of visualization and management tools:

[0010] Key parameters such as the computer room's airflow organization and temperature distribution lack intuitive visualization, making it difficult for administrators to quickly locate hot spots or evaluate the effectiveness of control strategies.

[0011] The decision-making process relies on offline analysis and manual intervention, which has a slow response speed and cannot meet the energy consumption optimization needs with high real-time requirements.

[0012] Therefore, a method for predicting computer room space energy consumption based on long short-term memory network is proposed. Summary of the Invention

[0062] Example

[0063] The method for predicting energy consumption of computer room space based on long short-term memory network provided in this embodiment is as follows: Figure 1 As shown, the following steps are included:

[0064] (a) Build a 3D digital twin model of the target computer room and generate time-series simulation data based on computational fluid dynamics (CFD) simulation. The time-series simulation data includes temperature distribution, power usage effectiveness (PUE), and air conditioning operating parameters.

[0069] By adopting the above technical solution, multi-dimensional time series data is generated through digital twin models and CFD simulation. Energy consumption and overheating risks are predicted by LSTM networks, and energy-saving suggestions are dynamically generated and visualized. This achieves accurate prediction and safe optimization control of computer room energy consumption, thereby improving energy management efficiency.

[0084] Among them, CFD simulation data covers the operating status of the computer room under abnormal working conditions, including air conditioning failure or extreme ambient temperature, to enhance the generalization ability of the LSTM model.

[0085] By adopting the above technical solution and training the model with simulation data covering abnormal working conditions, the system's predictive adaptability to extreme scenarios (such as air conditioning failure and high temperature environment) is enhanced, and the model generalization and system robustness are improved.

[0093] The LSTM model training module uses the Adam optimization algorithm, with a learning rate of 0.001, a maximum number of iterations of 3000, and a batch size of 64.

[0094] By adopting the above technical solution, through optimizing algorithms (such as Adam) and training parameter settings, the model convergence speed is accelerated, the training efficiency is improved, and the global optimality of the model parameters is ensured.

[0095] The inputs of the operation suggestion generation module include the current PUE, the number of air conditioners in operation, and the temperature set point, and the output is one of "turn off one air conditioner", "increase the temperature set point", or "maintain the current state".

[0114] Summary of working principle process:

[0115] 1. Data generation and model building stage:

[0116] Step 1: Build a 3D digital twin model of the target computer room. Use CFD simulation to simulate the temperature distribution, PUE, and air conditioning operating parameters of the computer room under different operating conditions (normal and abnormal), and generate simulation data with time series characteristics.

[0117] Step 2: Preprocess the simulation data, including:

[0118] Step 2.1 Sliding window division: Divide the continuous time series data into segments of fixed length (such as 64 time steps) to form model input samples.

[0119] Step 2.2 Wavelet transform denoising: decompose the data into different frequency bands, filter out high-frequency noise, and extract low-frequency effective features as model input.

[0120] Step 2.3 Feature extraction: Select key parameters (such as temperature gradient and air conditioning load) as training data to improve the input information density.

[0121] 2. Model training and prediction stage:

[0122] Step 3: Build an LSTM network model. Its structure includes an input layer (receiving preprocessed data), a dual LSTM layer (capturing temporal dependencies), a dropout layer (randomly discarding some neurons to prevent overfitting), a fully connected layer (integrating features), and an output layer (predicting PUE and overheating probability).

[0123] Step 4: The Adam optimization algorithm (learning rate 0.001) is used to train the model, and the parameters are updated through back propagation. The maximum number of iterations (3000) ensures model convergence, and the batch size (64) balances training efficiency and memory usage.

[0124] 3. Run the suggestion generation phase:

[0125] Step 5: Based on the current computer room operating parameters (such as the number of air conditioners, temperature set point, and real-time PUE), the trained LSTM model is used to predict the PUE change and overheating risk of two energy-saving strategies (turning off one air conditioner and raising the temperature set point).

[0126] Step 6: Generate recommendations based on security criteria:

[0127] If shutting down an air conditioner can reduce PUE without triggering overheating, and the current number of air conditioners is greater than 3, it is recommended to shut down one air conditioner.

[0128] If increasing the temperature set point can reduce PUE without risking overheating, then adjusting the temperature is recommended;

[0129] If none of the above conditions are met, maintain the current state to ensure safety first.

[0130] 4. Visualization and decision support stage:

[0131] Step 7: Use the Unity3D visualization interface to display the computer room's operating status in real time:

[0132] Cabinet temperature and air conditioning power are dynamically mapped in the form of heat maps, intuitively reflecting local hot spots and energy consumption distribution;

[0133] Operation suggestions are pushed through the interactive panel, and administrators can adopt them with one click or manually adjust parameters (such as adjusting air conditioning temperature with a slider);

[0134] The multi-view observation function allows administrators to view the airflow organization in the computer room, helping to optimize equipment layout or adjust cooling strategies.

[0135] 5. Closed-loop optimization and expanded applications:

[0136] The system continuously collects real-time data from the computer room, updates the digital twin model, and iteratively trains the LSTM network to form a dynamic optimization closed loop;

[0137] The modular design supports functional expansion (such as new sensor data access and multi-computer room collaborative management) to adapt to future technology upgrade needs.

[0138] Core logic closed loop:

[0139] Data generation → feature optimization → model prediction → security decision-making → visual feedback → dynamic iteration form a complete chain from simulation to actual application, realizing intelligent and refined energy consumption management of the computer room.
