基于CNN-MLP-ThermoAttention的数据中心三维温度场预测OA
Prediction of three-dimensional temperature fields of data center based on CNN-MLP-ThermoAttention
数据中心温度场分布直接影响运维安全、设备性能及冷却能耗.现有主流的计算流体力学(CFD)模拟虽能获取三维温度云图,但受限于计算机硬件算力,单次仿真计算耗时可达数小时,难以满足数据中心的实时运维需求.因此,本文以CFD数据为训练样本,提出热力学约束的注意力机制(ThermoAttention)——将热力学定律物理约束嵌入多头注意力机制,与卷积神经网络(CNN)、多层感知器(MLP)相耦合,构建出了可实时预测三维温度场的CNN-MLP-ThermoAttention神经网络框架;再结合点云技术与粒子系统,即可在基于Unity 3D的数据中心智能运维平台中实现三维温度场云图的动态重建与可视化.实验显示,该模型预测误差≤2%,单次耗时缩短至分钟级甚至秒级,为数据中心实时运维提供了高效支撑,也为高维度物理场实时预测提供了新思路.
The temperature field distribution in data centers directly affects operational safety,equipment performance,and cooling energy consumption.While the mainstream computational fluid dynamics(CFD)simulation can obtain 3D temperature contour maps,it is constrained by computing power,with a single simulation taking hours to days,failing to meet the real-time requirements of actual data center operation scenarios.To address this,this paper used CFD data as training samples and proposed the thermodynamics-constrained attention(ThermoAttention)mechanism,which embedded thermodynamic laws into the multi-head attention mechanism and coupled it with convolutional neural networks and multi-layer perceptrons to construct a neural network framework capable of real-time prediction of 3D temperature fields.Combined with point cloud technology and particle systems,dynamic reconstruction and visualization of temperature field contour maps were realized in Unity 3D.Experimental results showed that the model's prediction error was≤2%and a single prediction was shortened to minutes or even seconds,providing efficient support for real-time operation and maintenance of data centers and offering a new approach to real-time prediction of high-dimensional physical fields.
