Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of server heat dissipation monitoring, in particular to a server cluster radiator energy consumption intelligent monitoring system. BACKGROUND

[0002] In the information age, as the core carrier of data processing and storage, the stable operation of the server cluster is directly related to the smooth operation of various business systems. With the explosive growth of data volume and the continuous improvement of computing demand, the scale of the server cluster continues to expand, and the heat generated during operation also increases significantly. As a key device for maintaining the temperature balance of the server cluster, the energy consumption state of the radiator is closely related to the heat dissipation efficiency. Once the energy consumption is abnormal, not only will it increase the operating cost, but also it may cause the server to overheat and shut down, resulting in data loss or business interruption. The energy consumption monitoring of the server cluster radiator mostly adopts the traditional fixed cycle collection mode, and the collection frequency cannot be dynamically adjusted according to the actual heat dissipation demand. When the radiator has slight energy consumption fluctuations, the fixed cycle collection method may not be able to capture abnormal signals in time, resulting in a lag in abnormality discovery; while in the stable heat dissipation state, too frequent collection will cause resource waste. In terms of threshold judgment, the existing system usually only performs simple threshold comparison to generate a single abnormality prompt, lacking quantitative analysis of the deviation degree of the energy consumption parameter from the preset threshold, and it is difficult to accurately judge the severity and influence range of the abnormality. For the evaluation of heat dissipation efficiency, the existing technology often focuses on the monitoring of the heat dissipation result, while ignoring the time consumption and lag problem in the heat dissipation regulation process. This makes it impossible for the operation and maintenance personnel to fully grasp the response speed of the heat dissipation system, and it is difficult to optimize the regulation strategy. In addition, the regulation mechanism lacks dynamic correction ability, and the regulation strength is fixed and unchanged, which cannot be adaptively adjusted according to the change of the heat dissipation regulation efficiency, resulting in the occurrence of insufficient regulation or excessive regulation in some scenarios. The existing monitoring system lacks attention to overall stability and lacks statistical analysis of the total amount of abnormal signals and the frequency of loss of control. In the long-term operation process of the server cluster, a single abnormality may not immediately cause the system to fail, but after the accumulation of multiple abnormalities, the risk of loss of control will increase significantly. Due to the lack of effective loss of control frequency evaluation mechanism, the operation and maintenance personnel are difficult to predict the potential risk of the system in advance, and often only after the system fails to make remedial measures, increasing the difficulty of troubleshooting and recovery. These problems together lead to the lack of precision, timeliness and adaptability of the current server cluster radiator energy consumption monitoring, which cannot meet the demand of efficient operation and maintenance of large-scale server clusters.

[0007] Preferably, the regulation correction unit generates a collection period shortening instruction and sends it to the energy consumption collecting unit when the heat dissipation regulation lagging ratio exceeds the allowed range, and the energy consumption collecting unit shortens the collection period based on the heat dissipation regulation lagging ratio; The regulation modification unit generates a regulation intensity enhancement instruction and sends it to the threshold judgment unit when the heat dissipation regulation efficiency is lower than the preset standard, and the threshold judgment unit improves the power level of the heat dissipation regulation operation according to the regulation intensity enhancement instruction.

[0013] Preferably, the system stability monitoring unit obtains the total number of heat dissipation paths of the server cluster through the heat dissipation topology modeling unit, verifies the triggering validity of the system failure signal in combination with the proportional relationship between the out-of-control frequency and the total number of paths.

[0014] Compared with the prior art, the application has the beneficial effects that: The server cluster radiator energy consumption intelligent monitoring system effectively improves the limitations of the traditional monitoring mode through the collaborative work of each unit. The energy consumption collection unit adopts a periodic collection method to provide continuous basic data support for subsequent abnormality judgment. However, the collection period is not fixed and can be dynamically adjusted under the action of the regulation and correction unit, so that the collection frequency can be increased to capture detailed changes when the heat dissipation state fluctuates greatly, and the frequency can be reduced to reduce resource occupation when the state is stable, thereby achieving a balance between collection efficiency and resource consumption. The threshold judgment unit is no longer limited to simple threshold comparison, but generates different types of abnormal signals such as temperature, flow or pressure according to the specific values of the energy consumption parameters, so that the identification of abnormal types is more accurate. This classification identification method allows operation and maintenance personnel to quickly locate the source of the abnormality, avoids blind troubleshooting under the traditional single abnormality prompt, and reduces the time cost of problem diagnosis. The heat dissipation efficiency analysis unit realizes quantitative evaluation of the abnormality degree by calculating the deviation of the energy consumption parameter from the preset threshold, and the generated heat dissipation regulation lag ratio can directly reflect the response delay of the heat dissipation system to the abnormality. At the same time, the statistics of the time consumption of the heat dissipation regulation process provides a key basis for evaluating the heat dissipation regulation efficiency, so that operation and maintenance personnel can clearly understand the dynamic response capability of the heat dissipation system, and provide a direction for the optimization of subsequent regulation strategies. The regulation and correction unit performs bidirectional adjustment based on the heat dissipation regulation lag ratio and the heat dissipation regulation efficiency. On the one hand, by adjusting the collection period of the energy consumption collection unit, it ensures that abnormal signals can be captured in time to avoid missed judgment of abnormalities due to collection lag; on the other hand, by adjusting the heat dissipation regulation intensity, it makes the regulation measures match the actual heat dissipation demand, avoiding the expansion of abnormalities caused by insufficient regulation, and preventing energy waste caused by excessive regulation. The system stability monitoring unit can fully grasp the long-term running state of the heat dissipation system by calculating the out-of-control frequency in combination with the running time based on the total amount of abnormal signals. When the out-of-control frequency exceeds the preset threshold, the system failure signal can generate a potential system risk warning in advance, so that operation and maintenance personnel can take preventive measures before the system fails substantially, reduce business interruptions caused by sudden failures, and improve the continuity and reliability of the server cluster operation as a whole. The organic combination of each unit makes the entire monitoring system have stronger adaptability, accuracy and preventability, and can better cope with the complex and variable running environment of the server cluster radiator.

DETAILED DESCRIPTION

[0016] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the 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 in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0017] Please refer to Figure 1 The present application provides a server cluster radiator energy consumption intelligent monitoring system, which comprises: The temperature, flow, pressure and other energy consumption parameters of the server cluster radiator are periodically collected by the energy consumption collection unit, and the collection results are transmitted to the threshold judgment unit for threshold range comparison. When the parameters exceed the preset threshold range, the corresponding temperature abnormal signal, flow abnormal signal or pressure abnormal signal is generated. The radiator efficiency analysis unit receives the abnormal signal and related energy consumption parameters, calculates the deviation of the parameters from the threshold, generates the radiator regulation lag ratio, and calculates the regulation efficiency by counting the regulation time. The regulation correction unit dynamically adjusts the collection period according to the lag ratio and optimizes the regulation intensity based on the regulation efficiency. The system stability monitoring unit counts the total amount of abnormal signals and the running time, calculates the out-of-control frequency and generates a system failure signal when the threshold is exceeded, realizing real-time monitoring of the system state.

[0018] Embodiment 1: Please refer to Figure 2The threshold judgment unit receives the heat dissipation temperature, cooling liquid flow rate and pipeline pressure data transmitted by the energy consumption collection unit, and respectively compares them with the preset temperature threshold range, flow rate threshold range and pressure threshold range in real time. The temperature threshold range is set to 25-35°C, the flow rate threshold range is 5-8 L / min, and the pressure threshold range is 0.3-0.5 MPa. When it is detected that the heat dissipation temperature reaches 36°C, a temperature abnormality signal is generated; when the cooling liquid flow rate drops to 4.8 L / min, a flow rate abnormality signal is triggered; and when the pipeline pressure exceeds 0.52 MPa, a pressure abnormality signal is generated. The heat dissipation efficiency analysis unit extracts the specific parameter value corresponding to the abnormal signal, such as the 36°C value when the temperature is abnormal, and calculates the difference with the threshold endpoint 35°C to obtain a parameter offset of 1°C. The offset and the preset reference value 2°C generate a heat dissipation regulation lag ratio of 50%. At the same time, the time consumed from the temperature abnormality trigger to the recovery to 34°C is recorded, which is 180 seconds, compared with the standard time of 150 seconds to obtain a heat dissipation regulation efficiency coefficient of 1.2. For the flow rate abnormality condition, the 0.2 L / min offset of 4.8 L / min and the lower threshold 5 L / min is calculated, based on the reference value 0.5 L / min to generate a lag ratio of 40%, and the corresponding efficiency coefficient is recorded by recording the regulation time. The specific implementation is as follows: The energy consumption collection unit monitors the server cluster heat dissipation system in real time through a distributed sensor network. The sensor nodes are arranged at key positions such as the inlet and outlet of the radiator, the key nodes of the cooling pipeline and the surface of the heat exchanger. Each sensor node is equipped with a temperature probe, a flow meter and a pressure sensor, forming a multi-parameter synchronous collection capability. The collection module uses a polling mechanism to read data from all monitoring points according to a preset period, and the collection frequency is initially set to 60 seconds each time. The raw data collected is filtered and amplified by a signal conditioning circuit, and transmitted to the central processing unit through the CAN bus.

[0019] The threshold judgment unit has a multi-stage comparator array, which processes temperature, flow rate and pressure parameters respectively. The temperature comparator receives temperature data from the CPU heat sink and GPU heat dissipation module, and sets a double threshold comparison window. When it is detected that the temperature of a certain heat sink continuously exceeds the upper threshold, the comparator outputs a high level to trigger the temperature abnormality signal generation circuit. The flow rate comparator uses a differential input design to compare the flow rate difference between the cooling liquid main pipeline and the branch pipeline in real time, and judges in combination with the preset flow rate fluctuation range. The pressure comparator is configured with overvoltage and undervoltage detection channels, which immediately locks the abnormal state when the pipeline pressure exceeds the safe range.

[0020] The heat dissipation efficiency analysis unit includes a parameter offset calculation module and a regulation time consumption statistics module. The parameter offset calculation module receives the abnormal parameter value transmitted by the threshold judgment unit, first identifies the abnormal type and calls the corresponding threshold reference data. For temperature abnormality, the calculation module automatically selects the closest threshold boundary value for difference operation to obtain the absolute offset. The offset is sent to the proportional converter for proportional conversion with the preset standard offset to output the dimensionless lag proportion value. The regulation time consumption statistics module starts timing from the time when the abnormal signal is triggered, accurately captures the critical point when the parameter returns to the normal range by continuously monitoring the energy consumption parameter change curve, and records the complete regulation time span.

[0021] During the temperature abnormality processing process, when the heat dissipation fin temperature of a certain server node reaches an abnormal threshold, the sensor data packet is marked with a time stamp and transmitted to the central processor. The threshold judgment unit analyzes the data packet content, extracts the temperature measurement value and compares it with the set safety range. If a continuous over-limit condition is detected, a digital signal containing the abnormal node ID, abnormal type and over-standard value is immediately generated. The signal is transmitted to the event processing queue of the heat dissipation efficiency analysis unit through the data bus.

[0022] The heat dissipation efficiency analysis unit starts the abnormality processing process and extracts key parameters from the signal. Taking temperature abnormality as an example, the analysis unit first queries the historical running data of the node to obtain the temperature change trend curve. According to the difference between the current temperature value and the upper limit of the threshold, the instantaneous offset is calculated. At the same time, the regulation timer is started to monitor the change of the subsequent temperature data points. When the temperature value falls within the safety range, the timer stops and records the total time consumption. The system automatically compares the time consumption with the standard processing time of the same type of abnormality to generate an efficiency evaluation coefficient.

[0023] Flow abnormality processing uses a similar mechanism, but adds a flow fluctuation rate analysis function. When the cooling liquid flow is abnormal, the system not only detects the instantaneous flow value, but also calculates the flow change gradient in unit time. This helps to distinguish between sudden abnormalities and gradual failures. Pressure abnormality processing focuses on the pressure change rate and calculates the potential risk coefficient in combination with the pipe volume parameter.

[0024] The calculation of parameter offset uses a dynamic reference adjustment strategy. The system maintains a reference value database to record the typical offset range of various parameters under different working conditions. When calculating the current offset proportion, the system automatically refers to the statistical average value in the recent period of time, so that the calculation result is more consistent with the actual running state. For newly deployed nodes or replaced components, the system uses a gradual learning mechanism, using conservative reference values in the initial stage, and gradually optimizing the calculation model as the running data accumulates.

[0025] The regulation time-consuming statistics module adopts a multi-thread design, which can simultaneously track the disposal process of multiple abnormal events. Each abnormal event is assigned an independent timing channel to record the whole process time data from signal generation to parameter recovery. The system analyzes the time-consuming composition and distinguishes between active regulation time and system natural response time, providing more detailed data support for efficiency evaluation. The statistical results are stored according to the abnormal type and form a historical database for trend analysis.

[0026] The abnormal signal processing flow contains multiple verification links. When the threshold judgment unit generates an abnormal signal, it needs to be confirmed for three consecutive acquisition cycles before being officially recorded. This effectively avoids false alarms caused by transient interference. The confirmed abnormal event is assigned a unique event number, including information such as timestamp, node location, abnormal type, and severity level. Complete event records are written to non-volatile memory, and the real-time state database is updated simultaneously.

[0027] The output interface of the heat dissipation efficiency analysis unit provides a standardized data format, including the lag ratio value, regulation efficiency coefficient, and event characteristic code. These data are transmitted to the regulation correction unit through a high-speed data channel and are also collected by the system stability monitoring unit for long-term trend analysis. All data processing processes follow strict timing requirements to ensure the synchronization of real-time monitoring data and subsequent regulation instructions.

[0028] The system adopts a hierarchical alarm mechanism, automatically determining the abnormal level based on parameter deviation and regulation time. Level one triggers the regular regulation process, level two starts the enhanced regulation mode, and level three triggers the system-level emergency response. Each level corresponds to different acquisition frequency adjustment strategies and regulation intensity parameters, forming a step-by-step response plan. This design ensures system response speed while avoiding resource waste caused by excessive regulation.

[0029] The data acquisition link uses adaptive sampling technology, maintaining a basic sampling frequency under normal conditions and automatically increasing sampling density when detecting increased parameter fluctuations. Each sensor node has local cache capability, which can temporarily store critical data when communication is interrupted. The transmission protocol uses differential encoding and CRC checking to ensure data integrity and real-time performance. The central processing unit is configured with a dual-channel receiver mechanism, with the main channel processing regular data and the emergency channel dedicated to the priority transmission of abnormal event data.

[0030] The threshold management module supports dynamic adjustment, which can automatically optimize the threshold range based on environmental temperature, server load, and other external factors. Different temperature threshold curves are used for summer and winter conditions, and different pressure warning lines are set for high and low load periods. This dynamic threshold strategy effectively reduces the false alarm rate caused by seasonal factors and changes in operating mode. Threshold parameters are stored in programmable memory, supporting remote configuration and batch updates.

[0031] The abnormal signal generation circuit employs opto-isolation to prevent power interference from affecting signal quality. The digital signal output port is equipped with an impedance matching network to ensure signal integrity over long distances. All comparator circuits undergo periodic self-calibration, correcting for zero drift and gain errors using a built-in reference source. The analog signal processing channel is equipped with an anti-aliasing filter to eliminate the impact of high-frequency noise on measurement accuracy.

[0032] The heat dissipation efficiency evaluation algorithm employs a sliding window statistical method, analyzing the processing data of several recent abnormal events to calculate a moving average efficiency value. The evaluation results are standardized and converted into a percentage score for system decision-making reference. Algorithm parameters can be adjusted online based on actual operating performance to maintain the objectivity and applicability of the evaluation results. Historical efficiency data is stored in time series, supporting trend queries and comparative analysis for any time period.

[0033] Example 2: See Figure 3 The control and correction unit receives real-time data streams from the heat dissipation efficiency analysis unit. These data packets contain the heat dissipation control lag ratio and the heat dissipation efficiency coefficient. The system has an internal lag ratio evaluation window that continuously monitors the trend of this ratio. When the lag ratio exceeds the allowable upper limit three times consecutively, the instruction generation module initiates the cycle correction program. This program uses a proportional-differential algorithm to calculate a new acquisition cycle value, dynamically compressing the original 60-second reference cycle according to the current lag ratio. The correction instruction is transmitted to the control register of the energy consumption acquisition unit via a high-speed serial bus. The port mapped to address 0x3F8 receives the 32-bit control word. The high 16 bits of the control word store the correction coefficient, and the low 16 bits define the execution delay parameter. The clock management circuit of the energy consumption acquisition unit adjusts the sampling timer accordingly, shortening the cycle to the target value. The execution result is returned through the status register, completing the closed-loop control.

[0034] For heat dissipation regulation efficiency data, the control and correction unit employs a two-level judgment mechanism. The primary judgment compares the current efficiency coefficient with a preset standard value, while the secondary judgment analyzes the rate of change of this coefficient over time. When the coefficient value is below the standard threshold and the rate of change shows a negative growth trend, the enhanced instruction generation sequence is activated. The instruction code includes a control intensity level identifier; the current version defines four intensity levels from 0 to 3. Instruction transmission uses a reliable transmission protocol with a retransmission mechanism to ensure accurate reception by the threshold judgment unit. The instruction parser of the threshold judgment unit updates the heat dissipation control parameter mapping table based on the level identifier. The table records the fan speed curve coefficient, cooling pump duty cycle parameters, and refrigerant flow valve opening reference value. Taking a two-level to three-level upgrade as an example, the fan speed reference increases by 15%, the cooling pump duty cycle is adjusted from 60% to 75%, and the flow valve opening increases by 8%. The actuator receives the updated parameter set and outputs the corresponding control waveform through a pulse width modulation signal driver.

[0035] Meanwhile, the heat dissipation topology modeling unit initiates the node discovery program. This program polls the connection status registers of each heat dissipation node in the server cluster to obtain the physical connection topology between nodes. The main controller chip traverses the address space of the heat dissipation nodes via the I2C bus, reading the level identifier of each node. The level determination is based on the coolant flow direction: nodes directly connected to the main heatsink are defined as level one, nodes connected via a level one splitter are defined as level two, and the end heatsink belongs to level three. The node relationship matrix construction module converts the obtained connection information into an adjacency matrix for storage. The matrix row numbers represent node numbers, and the column values ​​record the connection direction identifier. The direction encoding uses an 8-bit binary scheme: East 00000001, West 00000010, South 00000100, North 00001000.

[0036] The node sorting algorithm reconstructs the adjacency matrix according to hierarchical priority. The system initializes the sorting index array, placing all first-level nodes at the beginning of the sequence, second-level nodes in the middle, and third-level nodes at the end. Nodes at the same level are arranged in ascending order of node number. After sorting, a node sequence array is generated, with each element containing the node ID, level value, and position index. Based on this sequence, the topology building engine extracts the distance data between adjacent nodes. The distance parameter comes from the physical coordinate values ​​in the node configuration register; the system automatically calculates the Euclidean distance and converts it into a standardized span value. The topology descriptor generation module encapsulates the node sequence, direction encoding, and span parameters into structured data packets. Each data packet contains: a node path identifier (4 bytes), the number of path nodes (2 bytes), a node ID sequence (variable-length array), a connection direction vector set (stored bitwise), and a span parameter array (floating-point sequence). Finally, a heat dissipation path topology database is constructed and stored in non-volatile memory in binary tree format.

[0037] The system periodically executes a topology verification process. The verification program reconstructs a connection graph based on the node sequence and compares it with the actual connection status returned by the physical probes. When a mismatch between the path topology and physical links is detected, a topology database reconstruction process is initiated. The reconstruction process employs an iterative correction algorithm: first, abnormal path data is frozen; then, node connection status is re-collected through a dedicated diagnostic interface; and finally, the confirmed connection information is incrementally updated to the topology database. A version control mechanism ensures that other modules can access historical topology data normally during the reconstruction period.

[0038] The execution status monitoring of control commands employs a dual-channel feedback mechanism. The main channel receives real-time status codes from the actuators, while the secondary channel monitors the actual heat dissipation parameter change curves. The main channel feedback information includes fan drive current, cooling pump operating frequency, and valve position sensor readings. These data are converted into execution percentages and dynamically compared with the command requirements. When the deviation consistently exceeds the tolerance value, the control correction unit triggers a compensation command sequence, automatically increasing the output strength of the control signal. The secondary channel uses temperature and flow rate change gradient data acquired by the energy consumption acquisition unit to verify the actual effectiveness of the control operation. The dual-channel data are aligned and analyzed on the time axis to generate a control quality assessment report, which is used to optimize subsequent command generation parameters.

[0039] The topology data access interface uses a paginated query method. Clients can query complete path information by specifying a path identifier code, or query related paths in reverse order by node number. Query requests are decomposed by the data routing processor and converted into multi-level index retrieval operations. The first-level index locates the path storage page, the second-level index extracts the path node list, and the third-level index obtains the connection direction and span parameters. Query results are returned in a structured data block containing node sequences and auxiliary parameters, prioritizing path completeness.

[0040] The heat dissipation node discovery program has dynamic expansion capabilities. When a new heat dissipation node is added to the server cluster, the node address is automatically added to the polling list. The system assigns a temporary hierarchical identifier to the new node and automatically corrects the hierarchical affiliation during the topology construction phase. The node location index update uses an incremental sorting algorithm, which only reorganizes the index value after the new node is inserted, improving system response efficiency.

[0041] The coolant flow direction detection mechanism employs a thermodynamic marking method. A tracer is injected at the main radiator inlet, and sensors at each node monitor the arrival time of the tracer. The system calculates the flow direction based on the propagation time difference to determine the node connection direction. This method is executed periodically to correct for possible changes in physical connections. Version control is introduced into the direction coding update process, and a complete change record of historical direction data is retained for analysis.

[0042] Ambient temperature compensation is incorporated into the calculation of the span parameter. After the distance sensor collects raw data, it performs linear correction according to a preset formula based on the current ambient temperature. The compensation coefficients are stored in a temperature-distance mapping table, which is generated through experimental calibration and includes compensation parameters ranging from -10℃ to 50℃. The calculation results are rounded to two decimal places before being stored in the topology database.

[0043] A handshake protocol is established for the transmission of control commands. Upon receiving a new command, the threshold judgment unit returns an acknowledgment code; if the adjustment and correction unit does not receive acknowledgment within a timeout period, it initiates a retransmission process. Three consecutive transmission failures trigger a fault alarm, notifying maintenance personnel to check the communication link. Command execution results utilize a feedback receipt mechanism; after completing parameter changes, the actuator sends a status report containing the actual output control signal characteristic values. This data is recorded in the execution log library as the primary basis for system performance evaluation.

[0044] The heat dissipation parameter adjustment operation is set with safety boundary limits. When increasing the intensity of regulation, the system monitors the pressure limit of the cooling system in real time. When the regulation command causes the pressure to approach the safety threshold, an adjustment buffer phase is automatically inserted. This phase adopts a gradual enhancement strategy: the initial adjustment is 60% of the target value, 80% is executed in the next control cycle, and finally the full adjustment is completed. This segmented execution method avoids oscillations caused by sudden changes in system load.

[0045] The topology visualization service module runs on a dedicated processor. This module reads structured data from the topology database and converts it into a graphical description language. Nodes are arranged hierarchically on different horizontal planes, with connecting arrows indicating flow direction, and line segment width positively correlated with span value. The visualization engine supports 3D view rotation, allowing users to interactively examine the details of each heat dissipation path. The topology map is updated synchronously with the modeling units to ensure real-time information presentation.

[0046] Example 3: See Figure 4 The path cross-analysis unit receives path topology data packets generated by the heat dissipation topology modeling unit via a high-speed data channel. Each data packet contains complete node sequence information. The data parser first extracts the path identifier and node count fields, converting the variable-length array format node ID sequence into a standardized set data structure. The system maintains a global node mapping table, recording the index of each node ID's occurrence position in all paths. The cross-detection algorithm employs multi-level hash comparison technology, first filtering potential cross nodes and then verifying actual cross relationships in the second round. For path A (node ​​sequence N1→N3→N5→N7) and path B (node ​​sequence N2→N3→N6→N7), the algorithm detects that nodes 3 and 7 exist in both paths simultaneously and marks them as candidate cross points.

[0047] The frequency statistics algorithm uses a sliding window counting method to analyze the distribution of each candidate node across all paths. The system establishes a node frequency matrix F, where rows represent node IDs and columns record the frequency of occurrence in different paths. The cross-validation module calculates the co-occurrence probability of nodes across multiple paths and filters out significant cross-nodes. Node 3 appears in 5 paths, and node 7 appears in 3 paths; these data are recorded in the cross-feature database. The frequency threshold comparator compares the actual frequencies with a dynamically adjusted benchmark value, which is automatically adjusted according to the system's operational phase: set to 2 times during initialization, increasing to 4 times during stable operation, and decreasing to 3 times during high-load phases. Node 3's 5 occurrences exceed the current phase threshold and are therefore confirmed as a valid cross-node.

[0048] The path cross-set generator uses verified cross nodes as the core of the association and reverse-searches for all paths containing those nodes. The search process employs an inverted index technique, quickly locating relevant path identifiers via node IDs. For node 3, the system finds shared relationships between paths A, B, and C, forming a preliminary cross-set. The set integrity validator checks the associations of these paths outside the cross nodes, confirming that node 7 also exists in the three paths, enhancing the credibility of the cross-set. The final generated cross-set data structure includes: a list of cross node IDs, an array of associated path identifiers, and a cross-strength coefficient. The cross-strength coefficient is calculated using the following formula: in: Indicates the cross strength coefficient. The number of cross nodes, It is the weight factor of the i-th intersection node (determined according to the node level). This represents the frequency of the i-th node in the path. This represents the highest frequency of occurrence among all nodes. This coefficient is used to quantify the density of path intersections, and its value ranges from 0 to 1.

[0049] The thermal label classification unit acquires cross-aggregate data through a dedicated interface and initiates the endpoint node analysis process. The endpoint node locator extracts the last node ID from the node sequence of each path and queries the corresponding location coordinates in the physical layout database of the server cluster. The infrared thermal imaging data acquisition module obtains a real-time thermal distribution map from the distributed temperature sensor network based on the coordinate information. The image processing algorithm converts the thermal data into standardized temperature range labels.

[0050] The visualization rendering engine for cross paths transforms the analysis results into graphical elements. In the 3D topology map, cross nodes are displayed as red cubes, and associated paths are represented by curves of different colors. Heat maps are presented through color rings at the ends of the paths: red rings represent high-temperature zones, and blue rings represent low-temperature zones. The visualization system supports interactive queries; clicking on any cross node displays detailed frequency statistics and associated path information.

[0051] The system implements a dynamic label update mechanism. When thermal imaging data changes significantly, the label reassessment trigger is automatically activated. A change detector continuously monitors temperature sensor readings; when the temperature change in a certain area exceeds 15% of the historical baseline value, a local label update process is triggered. The reassessment process prioritizes high-weight nodes and uses incremental updates to correct the label database. The version control system retains records of all label changes, supporting the retrospective analysis of thermal distribution at any given time.

[0052] The path cross-validation unit implements a multi-factor verification mechanism. The raw data validator checks the integrity and continuity of the node sequence to ensure there are no missing or duplicate node IDs. The logic validator confirms that the path direction conforms to the physical constraints of the cooling system, such as prohibiting loop paths. The frequency statistics validator compares real-time calculation results with historical trend data to detect abnormal fluctuations. When data anomalies are detected, the system automatically isolates the problematic data segment and reprocesses it using redundant calculation nodes.

[0053] The heat map tag database adopts a distributed architecture, with the primary replica stored on a central server and multiple read-only replicas deployed on edge computing nodes. The data synchronization mechanism uses incremental replication based on operation logs to ensure eventual consistency across replicas. The query optimizer automatically establishes a cache area for hot data based on request patterns, while frequently accessed tag data is retained in memory to accelerate query response.

[0054] The cross-node importance assessment module periodically performs a global analysis. The assessment algorithm comprehensively considers node cross-node frequency, thermal tag weights, and topological location factors to generate a node criticality score. The score results are used to optimize system resource allocation, with highly critical nodes configured with denser monitoring sampling frequencies and stricter anomaly detection thresholds. Node score data is also provided to the maintenance system to guide the optimization and modification of physical cooling facilities.

[0055] The system implements load balancing monitoring for cross-paths. The flow distribution analyzer calculates the coolant distribution ratio for each path using sensor data from the cross-nodes. When the load on a cross-node exceeds that of its adjacent nodes by 20%, a flow adjustment suggestion is generated. The adjustment algorithm considers path length, node level, and thermal tag factors to calculate the optimal flow redistribution scheme, and the output is the valve opening adjustment parameter.

[0056] The spatiotemporal correlation analysis module of thermal imaging data identifies anomalous thermal patterns. By comparing temperature distribution maps from different time periods, it detects the movement trajectory and diffusion trend of hotspot areas. The anomaly pattern identifier compares current thermal changes with a database of historical typical patterns to provide early warnings of potential heat dissipation bottlenecks. The warning information includes a list of affected paths and an estimated timeline of anomaly development.

[0057] The tag propagation model is used to predict changes in thermal distribution. Based on the current tag distribution and coolant flow direction, the algorithm simulates the heat transfer process in the path network. Model inputs include node heat capacity parameters, coolant flow rate, and ambient temperature; the output is a predicted tag distribution map for future time points. The prediction results are expressed in probabilistic form, assisting maintenance personnel in proactively deploying control measures.

[0058] The system implements multi-granularity cross-analysis capabilities. At the macro level, it analyzes the cross-analysis characteristics of the entire server cluster, identifying system-level thermal distribution patterns. At the meso level, it focuses on cross-analysis patterns in specific heat dissipation areas, assessing local heat dissipation efficiency. At the micro level, it delves into the detailed parameters of individual cross-analysis nodes, diagnosing potential flow resistance or heat exchange problems. The analysis results at each level are integrated and displayed through a unified interface, forming a complete health status report of the cooling system.

[0059] Example 4: The classification topology generation unit receives the heat dissipation path heat label groups processed by the heat label classification unit via the data bus. The data structure contains the mapping relationship between path identifiers and corresponding heat labels. The system initializes the label index table and merges heat dissipation paths with the same heat distribution labels into the same topology node. Taking a heat dissipation system actually deployed in a data center as an example, the system identifies three main types of heat labels: the "high temperature zone" label is associated with 5 paths, the "medium temperature zone" label is associated with 4 paths, and the "low temperature zone" label is associated with 3 paths. The merging process adopts a two-level clustering algorithm: the first round is coarse grouping according to label type, and the second round is fine adjustment based on path similarity.

[0060] Table 1: Topology node structure after heat dissipation path merging.

[0061] The topology node relationship builder creates an independent data structure for each merge group, recording the complete node sequence of all paths within the group. The structure includes a path topology fingerprint field, storing the hash value of the path's direction for fast comparison. The mapping relationship generator establishes a bidirectional index between topology nodes and merged paths. The forward index queries for contained paths using node IDs, while the reverse index locates the topology node to which the path belongs using its ID. The data structure uses a B+ tree organization, supporting efficient range queries and batch updates.

[0062] The generation of the server cluster thermal topology classification structure employs an iterative optimization method. The initial version is created based on static label assignment, and the system continuously receives real-time thermal data updates during operation. When a temperature change at the end node of a path causes a change in label type, the dynamic adjuster automatically removes the path from the original topology node and inserts it into the node corresponding to the new label. Migration operations maintain atomicity, ensuring that the system provides a consistent topology view at all times. The version control system records detailed information for each structural adjustment, including the change time, affected paths, and operation type.

[0063] The identification mechanism for high-load heat dissipation topology nodes is based on multi-dimensional evaluation. The node load calculator comprehensively considers three core indicators: duration of sustained temperature exceeding limits, flow rate fluctuation amplitude, and frequency of abnormal pressure. The evaluation process uses a sliding time window, assigning higher weight to indicator data within the most recent 15 minutes. The system calculates a dynamic load coefficient for each topology node, marking it as a high-load state when the coefficient exceeds the category baseline. Taking the TN-2024-01 node in Table 1 as an example, its maximum flow rate deviation of 22.4% triggers the high-load judgment condition.

[0064] After the heat dissipation efficiency analysis unit is connected to the classification topology, a dedicated monitoring channel is established to collect the operating parameters of high-load nodes. The data acquisition strategy distinguishes between two modes: normal sampling and anomaly tracking. In normal mode, basic temperature and flow data are collected at standard cycles; in anomaly tracking mode, the acquisition frequency is increased threefold and pressure gradient monitoring is added when parameter deviations are detected. The parameter processor performs moving average filtering on the raw data to eliminate the influence of transient interference on the analysis results.

[0065] The dynamic baseline update algorithm employs a gradual adjustment strategy. The system maintains two sets of baseline parameters: a long-term baseline calculated based on historical statistical values, reflecting the system's normal operating characteristics; and a short-term baseline derived from the average of the most recent 30 minutes, capturing changes in current operating conditions. When the parameter offset of a high-load node continuously deviates from the baseline, the regulator gradually corrects the baseline value in fixed steps, with each adjustment not exceeding 5% of the original value. This gentle adjustment method avoids drastic fluctuations in system parameters and maintains control stability.

[0066] The timing and statistics module enhances time measurement accuracy by employing a high-resolution clock to record the entire process of abnormal events. A timer is activated when an abnormal signal is generated by the threshold judgment unit, and a callback function mechanism listens for parameter recovery events. Time data is stored with nanosecond-level precision and can be converted to appropriate time units for subsequent analysis based on actual needs. Statistical results are archived by topological node category, and the timing data of multiple abnormal events within the same category form a time-series dataset.

[0067] The calculation of the lag ratio for heat dissipation regulation incorporates a topology weighting factor. The parameter offset calculation results for nodes in the high-temperature zone are multiplied by a correction factor of 1.2, while the values ​​for nodes in the mid-temperature zone remain unchanged, and nodes in the low-temperature zone are reduced by a factor of 0.8. This differentiated processing reflects the heat dissipation sensitivity of different thermal regions, making the generated lag ratio more consistent with actual regulation needs. The ratio value is limited before output to ensure that the result is within the effective range of 0-100%.

[0068] The system provides a topology visualization service, converting classification results into an interactive graphical interface. The main view displays the distribution of three types of topology nodes, using red, yellow, and blue colors to distinguish heat map label types. Clicking on any topology node expands a detailed information panel, displaying path animations and real-time parameter curves. The view supports timeline dragging, allowing users to trace back to any historical point in time regarding topology status and parameter changes.

[0069] The topology optimization suggestion engine periodically analyzes the classification results to identify potential heat dissipation bottlenecks. The analysis algorithm detects three types of abnormal patterns: cross-category path intersections, traffic imbalances within the same category, and blurred label boundaries. For detected problem patterns, the system generates a structured suggestion report, including a problem description, impact assessment, and adjustment plans. For example, when a node in a high-temperature zone is found to contain too many long paths, it is suggested to add intermediate heat dissipation points and reorganize the topology.

[0070] The reliability verification mechanism for thermal tags continuously monitors the match between the tag and the actual temperature. The verifier compares the current temperature of the end node with the range defined by the tag and calculates the tag confidence score. When the score is lower than the verification threshold, a tag reassessment process is triggered. The new tag allocation process incorporates historical path data analysis, referencing the thermal change patterns of the path over the past 24 hours to improve tag accuracy.

[0071] The system implements persistent storage and rapid recovery of the topology structure. The complete classification structure is periodically dumped into a compressed binary format, containing all path data, label mappings, and node relationships. A checksum is appended to the stored files to ensure data integrity, and corrupted files can be automatically recovered from a mirror copy. Upon system restart, the most recent valid topology snapshot is loaded first, and updates to the latest state are gradually performed in a background thread.

[0072] The operations and maintenance interface provides manual adjustment functionality for the topology. Authorized users can temporarily modify automatically generated classification results through the management console, such as forcing a specific path to be assigned to a particular topology node. Detailed operation logs are recorded for manual operations, including the state before modification, the content of the adjustment, and the operator's information. The system will refer to these manual adjustment records during subsequent automatic classification processes to gradually learn the classification preferences of operations and maintenance personnel.

[0073] The topology impact assessment module predicts and categorizes the impact of adjustments on the overall system. Before any structural changes are made, the simulator calculates the potential cascading effects, including changes in load on adjacent nodes and fluctuations in pressure at intersections. The assessment results are presented as a risk matrix to help operations personnel weigh the pros and cons of the adjustment plan. High-risk operations require secondary confirmation before execution to prevent accidental system instability.

[0074] Example 5: The system stability monitoring unit acquires abnormal signal records transmitted by the heat dissipation efficiency analysis unit via the data bus. These records include fields such as generation time, anomaly type, and recovery time. An internal circular buffer stores the most recent abnormal events, designed to store 72 hours of event data. The monitoring algorithm cyclically scans the buffer, counting the total number of abnormal events within the current observation window. The observation window duration is dynamically adjusted, defaulting to 24 consecutive hours, shortening to 8 hours when the average server cluster load exceeds 80% of the design capacity, and extending to 48 hours during low-load operation.

[0075] The runaway frequency calculation module employs a time-weighted statistical method. The module initializes a counter and a time accumulator. When a new abnormal signal is detected, the counter increments, and the time accumulator adds the duration of the event's impact. The clock management circuit triggers a calculation cycle every 300 seconds. The ratio of the number of abnormal events to the service runtime within the statistical cycle generates the raw frequency value. The raw data is smoothed using a second-order Butterworth filter to obtain the final runaway frequency output value. The calculation process considers clock drift correction, and all time parameters use UNIX timestamp format to avoid statistical errors caused by date switching.

[0076] The total number of heat dissipation paths is obtained in real time through the update interface of the heat dissipation topology modeling unit. When the topology changes, the modeling unit actively pushes path addition / reduction notifications. The monitoring unit maintains a mirror copy of the current total number of paths, and the copy update uses a dual-write mechanism to ensure data consistency. The path counter has an anti-jitter design; repeated topology reconstructions within a short period of time only trigger the final state update, avoiding intermediate states from interfering with calculation accuracy.

[0077] The failure verification process employs a three-level confirmation logic. When the out-of-control frequency first exceeds a preset threshold, the initial verification phase is initiated: analyzing the distribution characteristics of the ten most recent anomalies to check if they are concentrated in a specific topology category. The percentage of anomalies in high-temperature zone nodes is queried through the topology classification interface; if this percentage exceeds a warning line, secondary verification begins. Secondary verification focuses on the control response time, extracting the average recovery time for similar anomalies from the historical database and comparing it with the current recovery time. Tertiary verification calculates the distribution density of anomalies along the heat dissipation path to identify any chain reactions of localized path failures.

[0078] Path weight calculation takes topology location factors into account. The primary heat dissipation path is assigned a weight coefficient of 1.2, while secondary paths are assigned a weight of 0.8. Weight data is stored in the path attribute table and automatically assigned based on the hierarchical labeling of the topology modeling unit. During weighted calculation, each anomalous event is multiplied by the weight of its corresponding path, and the accumulated result is divided by the total weight to obtain the weighted runaway frequency. This design ensures that anomalies on the main path have a greater impact, preventing occasional failures on secondary paths from interfering with system-level judgment.

[0079] The system failure signal generation process incorporates multiple protections. The signal triggering circuit connects to three parallel comparator outputs, activating only when all three comparators simultaneously detect an out-of-range condition. The physical signal output interface is equipped with opto-isolation devices to prevent false triggering due to electromagnetic interference. The digital signal encoding uses Manchester code format to enhance anti-interference capabilities. The signal transmission channel uses a dedicated line independent of the data bus to ensure the transmission priority of alarm signals.

[0080] A dynamic tuning mechanism for the runaway frequency threshold operates continuously. The initial threshold baseline is set to 0.8 abnormal events per hour, and the system executes a threshold optimization program every 24 hours. The optimization algorithm analyzes the distribution characteristics of historical abnormal data and selects the 24 hours with the most stable operation over the past 30 days as the gold standard value. Considering the seasonal impact of ambient temperature, the operating threshold is increased by 20% in winter and maintained at the baseline value in summer. When signs of hardware aging are detected, the maintenance factor module automatically relaxes the threshold constraint.

[0081] The event attribution analysis module assists in failure diagnosis. This module labels each abnormal event with a possible cause code, including common fault types such as coolant loss, pump power reduction, and heat exchange blockage. It statistically analyzes the distribution ratio of different causes, generating a root cause analysis report for the failure event. The report data is correlated with corresponding failure signals, providing a reference for subsequent maintenance decisions.

[0082] System status recovery monitoring continues to run after a failure signal is issued. After maintenance personnel intervene, the monitor tracks the decline curve of the frequency of abnormal events. Three recovery judgment conditions are set: the failure frequency is below 75% of the threshold for six consecutive hours; the weighted frequency value returns to the normal range and continues for three statistical periods; the last abnormal event has not been reproduced for 24 hours. If any condition is met, the failure signal is turned off and a system recovery report is generated and archived to the log system.

[0083] Timestamp synchronization ensures the precise timing of event records. The system deploys an NTP server synchronized with satellite clocks, and all monitoring units use the same time source. Abnormal events are recorded with millisecond-level accuracy and time zone information is added for collaborative analysis across multinational data centers. A leap second compensation mechanism is added to time-series data storage to prevent event sequence corruption caused by time jumps.

[0084] The audit trail function for failure signals records the operation history in detail. Each time a signal is triggered or deactivated, an audit entry is generated, containing a complete snapshot of environmental parameters: server load rate, ambient temperature and humidity, cooling system operating mode, and other related parameters. Audit logs are encrypted and stored in tamper-proof storage, supporting full lifecycle accountability. The log analyzer automatically detects abnormal operation patterns to prevent unauthorized signal status changes.

[0085] The maintenance collaboration interface connects failure signals to the work order system. When a signal is activated, a fault work order is automatically generated and dispatched to the on-duty engineer. The work order includes the latest anomaly distribution diagram and root cause analysis summary. Engineers can confirm receipt on their mobile devices and close the work order using a verification code after maintenance is completed. The system automatically detects the work order processing time limit; if the work order is not processed within the time limit, the alarm level is automatically escalated.

[0086] A redundant monitoring mechanism is deployed to provide auxiliary monitoring channels. A backup computing core runs independently outside the main monitoring unit, receiving the same input data but using a simplified algorithm. The results from both channels are compared by an arbitrator; if the difference exceeds the tolerance range, a diagnostic mode is activated. The arbitrator prioritizes the main channel data, but seamlessly switches to the backup system when a hardware malfunction is detected in the main channel. The hot standby system maintains real-time data synchronization, ensuring that the switchover process does not affect continuous monitoring functionality.

[0087] The frequency of out-of-control events is visualized using a waterfall chart. The horizontal axis represents the timeline, and the vertical axis represents the frequency values. Different severity levels of out-of-control areas are rendered in different color zones. The view supports ten levels of time zoom, providing a comprehensive overview from minute-level details to monthly trends. Hovering the cursor displays detailed statistical parameters for the current time point, including a detailed list of abnormal events and a snapshot of the relevant topology.

[0088] The on-site simulation test interface is used for system self-testing. During testing, a simulated abnormal signal sequence is injected to check the response accuracy of the entire monitoring link. The test mode is physically isolated from the normal operation mode to prevent test data from contaminating real monitoring records. A compliance report of the test results is automatically generated, including latency data and calculation error rates for each processing stage, used for periodic calibration of monitoring accuracy.

[0089] The system continuously improves its analysis of historical data on failure signals. Machine learning algorithms identify early warning patterns that exceed frequency limits, such as continuous small anomalies increasing over specific periods. The predictive analytics engine provides early warnings of potential stability deterioration trends, shifting maintenance to a preventative phase. The system generates weekly monitoring performance reports, calculating the effective alarm rate and false alarm ratio, driving continuous optimization and updates to monitoring parameters.
