[0002] With the continuous expansion of the scale of data centers and the complexity of the operating environment, traditional operation and maintenance monitoring methods are difficult to meet the requirements of rapid perception of multi-source information, spatial positioning and trend prediction. The current common data center monitoring system mainly uses two-dimensional panels, tabular data or local video display, which has the significant shortcomings of information fragmentation, delayed abnormal response, lack of causal support for control operation, etc. Especially in the face of complex events such as sudden temperature rise and equipment failure spread, there is a lack of unified modeling and semantic linkage mechanism for multi-modal data, which leads to insufficient intelligent analysis and prediction ability, affecting system stability and operation efficiency.
[0003] Some existing research has proposed a scheme combining sensor data and image information for state monitoring, such as combining camera images and thermal sensor data for anomaly detection, but it is mostly limited to local areas, single modal features or static analysis, lacking multi-modal fusion, interactive visualization and control decision support capabilities based on a unified spatial model. In the field of image processing, although multi-modal visual models such as CLIP and ViT have been widely used in image-text semantic understanding, there is still a lack of mature solutions on how to collaboratively build a system-level analysis and control framework with heterogeneous information such as physical data and operation logs.

[0107] The data fusion unit is used for fusing the physical features, visual features and semantic features in the unified three-dimensional space coordinate system and time dimension, to generate a multi-modal fusion feature tensor wherein x, y, z represent three-dimensional space coordinates, and t represents time.
[0108] (2) Three-dimensional particle modeling module
[0109] The three-dimensional particle modeling module is used to construct a particle space structure of the data center based on a Voronoi diagram and a Delaunay triangulation method, to establish a mapping relationship between the particles and data items in the multi-modal fusion feature tensor, and to dynamically adjust the visualization resolution level of the particles according to the distance between the particles and the current view angle, and to output the current particle state set.
[0110] Specifically, as shown in Figure 3 the construction method of the particle space structure includes:
[0111] The physical sensor nodes (such as temperature and humidity sensors, power consumption meters, smoke sensors, etc.) deployed in the space of the data center are taken as space seed points, and a weighted Voronoi diagram is used for three-dimensional space region division, wherein the weight value of each physical sensor node is related to the sensor perception coverage, the historical abnormal record frequency, or the importance of the region (such as the core server area being more important than the peripheral area); based on the above weighted results, the three-dimensional space sub-region dominated by each sensor node is demarcated, ensuring that the space division is reasonable and has fault sensitivity;
[0112] The centroid set (i.e. the geometric center or feature point of the region) is extracted in the weighted Voronoi region, and Delaunay triangulation is performed on the centroid set to construct a three-dimensional particle network structure; the network has good spatial coverage and topological analyzability, which is beneficial to subsequent information propagation, reasoning and visualization operation;
[0113] After the construction, a one-to-one mapping relationship is established according to the tensor values in the multi-modal fusion feature tensor in the region where each particle is located, so that each particle can carry the fusion perception information of the region where it is located; the mapping data includes but is not limited to: current values of physical sensors (temperature and humidity, power consumption), video visual features, semantic event labels, etc.; the mapping relationship gives the particles multiple source attributes, making the particles become the carrying units of spatial data.
[0114] The three-dimensional particle modeling module monitors the local variation gradient of the multi-modal fusion feature tensor during system operation, and dynamically adjusts the particle distribution structure based on a preset reconstruction threshold, refines the particles in high heterogeneity regions (such as rapid temperature changes), increases the particle density to improve the monitoring accuracy, and performs particle aggregation reconstruction in stable regions (slow changes, low risk), reduces the particle density to reduce the computational burden.
[0115] The three-dimensional particle modeling method described in this embodiment enables the system to construct an efficient and adjustable spatial particle model based on the actual deployment environment, significantly improving the visualization and spatial analysis capabilities of multimodal data.
[0116] Furthermore, the 3D particle modeling module determines the visualization resolution level of each particle based on the spatial distance between each particle and the current viewpoint center point and the temperature gradient of the region where the particle is located. The resolution level scheduling mechanism specifically includes:
[0117] For each particle p i Calculate the Euclidean distance d between the particle and the center of the viewpoint. i Simultaneously calculate the magnitude of the temperature gradient in the local region where the particle is located.

[0124] Based on particle rendering weight W i Values in the range [0,1] correspond to different visualization resolution levels, and determine whether to retain, aggregate, or refine the rendering granularity of the particle in the current frame;
[0125] During system operation, the visualization resolution level of each particle can be dynamically updated, supporting continuous visual transitions and smooth presentation, ensuring that particles in abnormal hot spots are rendered delicately while areas far from the viewpoint and areas with slow changes are dynamically simplified.
[0126] In one preferred embodiment, the current particle state set at least includes:
[0127] a three-dimensional coordinate position (x i ,y i ,z i ) of the particle for spatial positioning;
[0128] a real-time monitored temperature value T i , a humidity value H i , and a power consumption value P i for characterizing the physical environment state of the space region corresponding to the particle;

[0138] Specifically, the local conceptual score LC is based on a weighted average method of fusing local semantic heat and mask area ratio, used to measure the semantic concept saliency of the local area where the particle is located.
[0139] The calculation formula of the local conceptual score LC is as follows:
[0140]
[0141] In the formula, p i represents the i-th particle, LC(p i ) is the local conceptual score of the particle p i ; α is a local saliency and heat weighting factor, 0 < α < 1; m i is the semantic mask area corresponding to the particle p i ; RTA(x, y) represents the semantic heat map intensity at the two-dimensional coordinate (x, y) (Refined Text Alignment); Area(m i ) is the area of the area corresponding to the mask m i ; Area(M) is the total area of all masks.
[0142] The global conceptual score GC is calculated by the image-text embedding similarity of the Alpha-CLIP model, used to evaluate the global semantic consistency between the particle image area and the target semantic text.
[0143] The global conceptual score GC is calculated by the Alpha-CLIP model as follows:
[0144]
[0145] In the formula, GC(p i ) is the global conceptual score of the particle p i ; is the normalized semantic embedding vector corresponding to the target text (such as the alarm description); is the normalized visual embedding vector corresponding to the image area where the particle p i is located.
[0146] The local visual score LV is obtained by calculating the feature similarity of the support image and the current image in the local area of the particle, and the local average aggregation of the spatial matching matrix is included in the calculation process.
[0147] The local visual score is used to evaluate the visual consistency between the area where the current particle is located and the support image and the current image. The score measures the visual semantic similarity between the known device or state area in the support sample and the corresponding area in the current operation scene, and is one of the important indicators for realizing spatial anomaly recognition and anomaly tracking.
[0148] In the specific implementation process, the calculation of the local visual score LV includes the following steps:
[0149] The support image I s and the current image I q are input into a pre-trained visual encoder (such as DINO v2, CLIP or Vision Transformer) at the same time.
[0150] For the three-dimensional spatial coordinates of each particle p i , the projection area R i of the particle in the image plane is located, and the corresponding set of visual embedding vectors is extracted:
[0151] F s = {f s (x, y)}, F q = {f q (x', y')}, (x, y), (x', y') ∈ R i ;
[0152] The cosine similarity calculation is performed on the embedding features of the support image and the current image in the local area R i of the particle, and a spatial matching matrix is obtained:
[0153]
[0154] On the basis of the matching matrix M, the local average aggregation is performed on the maximum matching value, and the local visual score LV of the particle is calculated: On the basis of the matching matrix M, the local average aggregation is performed on the maximum matching value, and the local visual score LV of the particle is calculated:
[0155]
[0156] The score reflects whether the local area of the current image has a similar semantic area in the support image, so as to be used for judging whether the device state is consistent, whether the structure is changed or whether the anomaly exists.
[0157] The visual encoder used in the application can be selected from the current mainstream image representation learning network, including but not limited to:
[0158] CLIP (Contrastive Language-Image Pretraining) model;
[0159] DINO or DINO v2;
[0160] LoFTR (Detector-Free Local Feature Matching);
[0161] Swin Transformer, ViT-B, and other lightweight self-attention structures.
[0162] The global visual score GV is the overall embedding distribution between the support image and the current image extracted by the ViT or DINO model, and the EMD (Earth Mover's Distance) is used to measure the similarity of the particle region feature distribution between different images.
[0163] The calculation formula of the global visual score GV is as follows:
[0164] GV(p i )=1-EMD(F s (p i ),F q (p i ));
[0165] In the formula, GV(p i ) is the global visual score of particle p i , the value closer to 1 indicates closer; F s (p i ) and F q (p i ) are the feature distributions of the support image and the current image in the region of particle p i .
[0166] Further, a context semantic consistency factor γ(p i ) is introduced in the multi-modal scoring analysis module, which gives the model a modeling structure for understanding the context, and scores the consistency of particle semantics and the global description of the current operation and maintenance scene by a multi-modal large model (such as LLaVA or GPT-4o), with a value range of [0, 1], which is used to adjust the local concept score and the global concept score to form the revised score item:
[0167] LC′(p i )=LC(p i )·γ(p i ), GC′(p i )=GC(p i )·γ(p i );
[0168] In the formula, LC′(p i ) is the revised particle p iLocal concept score; GC′(p i ) represents the corrected particle p i Global concept score;
[0169] Introducing semantic-behavior association vector a(p) i ), obtained through collaborative reasoning of text and video modalities, is used to predict the potential causal relationship between the region where the particle is located and historical operation and maintenance events, and to calculate the behavior enhancement weight term R(p i This is used to assess the degree of matching between particles and expected risk events.
[0170] R(p i )= <a(p i Emb event >;
[0171] In the formula, Emb event is the semantic embedding vector of a known historical fault event; <·,·> represents the vector dot product, which characterizes the potential causal relationship between the particle and the fault semantics;
[0172] Calculate the particle information entropy based on the multimodal score distribution of the local region where the particle is located:
[0173]
[0174] In the formula, H local (p i ) is particle p i Information entropy of the surrounding local score distribution; j is the score type index, j∈{1,2,3,4}, corresponding to local concept score, global concept score, local visual score, and global visual score, respectively; S j (p i ) is particle p i The score value of the j-th item; H global The mean entropy of the score distribution for all particles; i This indicates that the average value is taken over all particle numbers i.
[0175] Define the local-global entropy difference ΔH(p) i )=H local (p i )-H global The weights of each weighting term are adjusted as follows:
[0176] β′ j (p i )=β j ·(1+λ·△H(p i ));
[0177] In the formula, △H(p) i ) is particle p ithe local-global entropy difference of the anomaly score distribution; λ is the entropy difference adjustment coefficient, reflecting the amplification effect of score difference on weight; β j represents the base weight of the jth score; β′ j i is the jth weighted coefficient after dynamic adjustment for particle p i .
[0178] Calculate the final weighted score S of the particle:
[0179] S(p i )=β′1(p i )·LC′(p i )+β′2(p i )·GC′(p i )+β′3(p i )·LV(p i )+β′4(p i )·GV(p i );
[0180] In the formula, S(p i ) is the final weighted score of particle p i ; LV(p i ) is the local visual score of particle p i .
[0181] Determine whether it constitutes an abnormal hotspot area, and the abnormal prediction condition is as follows:
[0182]
[0183] In the formula, τ1 is an anomaly score threshold value for screening significant score areas; is the temperature change gradient at the position of particle p i , indicating the trend of temperature change; θ1 is a temperature change gradient threshold value, reflecting the risk boundary of rapid change area; M heat (p i ) is a historical failure mask; θ2 is a temperature mask heat intensity threshold value for screening high heat areas, and areas with insufficient heat change are excluded to improve recognition accuracy; ρ is a behavior correlation determination threshold value for screening areas most relevant to known fault types to prevent false positives.
[0184] Introduce a context semantic consistency factor to enhance the adaptability of the score to the context of operation and maintenance events and prevent local abnormal amplification misjudgment; introduce a behavior potential vector a(p i ), and by taking the dot product with the score results as the adjustment coefficient, the score heat map can improve the prediction ability of future possible failure trends; the score distribution difference between the particle peripheral region and the overall space is dynamically adjusted to fuse the weight, the score information entropy difference is introduced and mapped as a coefficient adjustment function, the weight expression of the abnormal concentration area is adaptively strengthened, and the balance between model sensitivity and robustness is improved.
