[0024] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0025] Embodiment 1: Embodiment 1: like Figure 1 As shown, the present application provides a multi-port POE power supply method, including steps S100 to S500.

[0026] Step S100: collecting port power supply parameters of a multi-port power supply device, performing data processing on the port power supply parameters, and obtaining port power data and power supply priority data.

[0027] In this step, the port power supply parameters of each port of the multi-port power supply device are collected in turn, including the current, voltage, load type and other information of each port, and the collected data is parsed and calculated through the data processing algorithm. Specifically, the processing algorithm calculates the port current and voltage data to obtain the actual port power, and generates the power supply priority data of the port in combination with the device configuration file.

[0028] For example, in actual applications, for an 8-port PoE power supply device, the collected port power supply parameters include the current value of each port is 0.3A-0.8A and the voltage value is 48V. Through calculation, it can be obtained that the power range of each port is 14.4W-38.4W, and priority data is allocated according to the type of port load (such as camera, AP, etc.).

[0029] Step S200: Generate a port load map based on the port power data, map the port load map and the power supply priority data, and obtain a port power allocation strategy.

[0030] In this step, the port power data calculated in step S100 is visualized to generate a port load map for each port, which shows the power demand of each port and the load relationship between adjacent ports. Specifically, the port load map is combined with the power supply priority data to establish a power supply priority rule to ensure that the power supply demand of high-priority ports is met first in the strategy.

[0031] For example, in a surveillance system, port 1 is connected to a high-power infrared camera, and ports 2-4 are connected to ordinary cameras. The port load map shows that the power demand of port 1 is higher than that of other ports. By mapping the power supply priority data, the allocation strategy will give priority to meeting the power demand of port 1.

[0032] Step S300: Calculate the port power allocation strategy to obtain the port power threshold and the remaining power data, generate a power supply control sequence based on the port power threshold and the remaining power data, and generate port adjustment data based on the power supply control sequence.

[0033] In this step, the maximum power allocation upper limit of each port, i.e., the port power threshold, is calculated based on the port power allocation strategy, and the total remaining power data of the multi-port power supply device is calculated. Specifically, a power supply control sequence is generated based on the port power threshold and the remaining power data, and the sequence includes instructions for adjusting the power of each port. Subsequently, port adjustment data is generated by parsing the power supply control sequence, and the port adjustment data includes specific port adjustment schemes, such as reducing power, closing low-priority ports, etc.

[0034] For example, assuming the total device power is 100 W, the port power allocation policy determines that port 1 is 38.4 W, ports 2-4 are 14.4 W each, the total demand is 81.6 W, and the remaining power is 18.4 W. If port 5 needs to turn on a device with a load of 15 W, the port adjustment data will release power resources by shutting down the low-priority port 4.

[0035] Step S400: Optimize the port power allocation strategy according to the port adjustment data to obtain the optimized port power allocation strategy, and use the optimized port power allocation strategy to detect abnormal ports of the multi-port power supply device to obtain port power data and port power supply status data.

[0036] In this step, the port power allocation strategy is optimized according to the port adjustment data, and the power allocation rules are updated to improve the adaptability of power supply. At the same time, the power supply status of each port is detected in real time through the optimized port power allocation strategy, focusing on monitoring the power data fluctuations and power supply abnormalities of abnormal ports. Specifically, the anomaly detection algorithm combines the port power data and power supply status data for comparison to quickly locate the abnormal port.

[0037] For example, when a device is running, a power surge occurs on port 2 due to a load short circuit. The optimized port power allocation strategy detects the anomaly in time and automatically isolates port 2 to ensure normal power supply to other ports.

[0038] Step S500: Calculate the port power data and the port power supply status data to obtain a global power supply balancing parameter, and use the global power supply balancing parameter to optimize and control the power supply of the multi-port power supply device.

[0039] In this step, the port power data and port power supply status data of all ports are summarized and calculated to generate a global power supply balancing parameter. Specifically, this parameter is used to measure the overall power supply balance of the current device and guide the dynamic adjustment of the power supply control logic to achieve the goal of balanced power supply.

[0040] For example, in a power supply device, the global power balancing parameters can reflect the impact of excessive power demand on a certain port on the overall power supply. The device adjusts the power supply of low-priority ports based on the parameters to balance the power distribution among the ports.

[0041] In this implementation, the port power supply parameters of the multi-port power supply device are collected and the port power supply parameters are processed to generate port power data and power supply priority data. Then, a port load spectrum is generated based on the port power data, and the port power allocation strategy is obtained by combining the port load spectrum and the power supply priority data mapping. The port power allocation strategy is further calculated to obtain the port power threshold and the remaining power data, and a power supply control sequence is generated based on the port power threshold and the remaining power data, and finally the port adjustment data is generated based on the power supply control sequence. After optimizing the port power allocation strategy using the port adjustment data, the abnormal ports of the multi-port power supply device are detected to obtain the port power data and the port power supply status data, and the global power supply balancing parameters are calculated. Finally, the global power supply balancing parameters are used to optimize the power supply of the multi-port power supply device. Efficient power allocation and power supply management of the multi-port power supply device are realized, the port power allocation strategy is optimized, and the power supply efficiency is improved. Its innovation lies in generating a power supply control sequence and detecting abnormal ports in real time based on it to ensure the overall performance and stability of the power supply device. In addition, by obtaining global power supply balancing parameters, the problem of low power supply efficiency caused by dynamic changes in port load and abnormal ports is effectively solved, thereby achieving precise control of multi-port power supply equipment and maximizing resource utilization, and improving the problems of uneven power distribution, low power supply efficiency and untimely identification of abnormal ports when the port load changes dynamically or the equipment is abnormal.

[0042] Embodiment 2: In step S100, port power supply parameters of a multi-port power supply device are collected, wherein the port power supply parameters include port voltage data and port current data.

[0043] The port voltage data and port current data are collected by sampling all ports of the multi-port power supply device one by one. Specifically, the port voltage value and port current value are collected in real time using a high-precision sampling circuit, and the collected data is preliminarily filtered to remove interference noise. At the same time, the voltage change and current change of each port are recorded using a timing sampling technology to construct a port current change sequence and a port voltage change sequence. These sequences contain the electrical characteristic information of the port, and the port current change sequence and the port voltage change sequence are further calculated using the power calculation formula to obtain the port power data and port electrical stability data. The port power data indicates the actual power usage of each port, and the port electrical stability data reflects the load stability of the port and the fluctuation amplitude of the electrical state.

[0044] For example, in actual applications, the port voltage range of a multi-port PoE power supply device is 47V-49V, and the port current range is 0.3A-0.8A. Through the timing sampling technology, the fluctuation sequence of the port voltage between 47.5V and 48.8V and the change sequence of the port current between 0.35A and 0.75A can be recorded. According to the power calculation formula (power = voltage × current), the power data range of each port can be calculated as 16.625W to 36.6W. At the same time, by analyzing the stability of voltage and current, the electrical stability data of the port can be determined, such as whether the port has a short-term current fluctuation or the voltage drop exceeds the threshold.

[0045] The port voltage data and the port current data are sampled in time series, and the port current change sequence and the port voltage change sequence are constructed based on the sampling results. The port current change sequence and the port voltage change sequence are calculated to obtain the port power data and the port electrical stability data.

[0046] By comparing and analyzing the port electrical stability data, the stability data is combined with the load type and port usage records of the multi-port power supply device. Specifically, the port electrical stability data is evaluated in detail in combination with the demand characteristics of the load device to construct a stability curve, and the port electrical stability data is mapped to generate port load status data. The port load status data can comprehensively characterize the power supply load situation of each port and the power supply change trend.

[0047] For example, in the process of generating port load status data, if the port electrical stability data detects that the port current fluctuation range exceeds the set threshold (such as ±0.5A) in a short period of time, the port load status is determined to be unstable and affected by non-standard equipment or overload. After data mapping processing, the results reflecting the port electrical fluctuation and the real-time load status can be obtained in the port load status data.

[0048] The port electrical stability data is mapped to obtain the port load status data, and the port power data is correlated and analyzed using the port load status data to obtain the port status data.

[0049] By processing the port electrical stability data into a structured data, the port electrical stability data is mapped to the port load status data. The mapping process includes stability value classification and load status mark generation. Specifically, the port electrical stability data is characterized and quantified in combination with the port's operating environment and load type, and the load status category of each port is marked, such as "light load", "medium load", "heavy load", etc. At the same time, the port load status data is combined with the port power data through an algorithm, and correlation analysis is performed to generate the port status data. The port status data comprehensively reflects the real-time load situation and stability of the port.

[0050] For example, in an actual scenario, the electrical stability data of a port shows that the voltage variation is within 0.5V and the current fluctuation is ±0.1A, and the "stable-medium load" load status data is generated through mapping. Through correlation analysis, the port power data is matched and supplemented to the port status data, showing that the power usage is 24W and the electrical fluctuation is stable.

[0051] A port operation sequence is generated based on the port power data and the port status data, and the port status data is mapped using the port operation sequence to obtain port load characteristic data and port historical power supply mode data.

[0052] By performing time series analysis on the port power data and port status data, the real-time operation information of the port is integrated into a port operation sequence, which records the state change trend of each port in different time periods. Specifically, the port operation sequence is dynamically mapped with the port status data using a mapping algorithm to generate port load characteristic data, which captures the load change law, fluctuation characteristics and long-term stability of the port. At the same time, by performing historical data comparison and analysis on the port operation sequence, the historical power supply mode data of the port is extracted to describe the power supply behavior and characteristic mode of the port.

[0053] For example, in a cycle, the operation sequence of a port shows that the power gradually increases from 10W to 25W and remains stable. Its status data is mapped to load characteristic data, indicating that the port load gradually increases but the fluctuation is small. Combined with this, its historical power supply mode shows that it has been in a medium-load power supply state for a long time, with occasional peak power supply demand.

[0054] The port load characteristic data is calculated to obtain the port stability parameter, and the port historical power supply mode data is processed based on the port stability parameter to obtain the power supply priority data.

[0055] By calculating the fluctuation characteristics, load trends and load balancing in the port load feature data, the port stability parameter is generated, which quantitatively describes the load stability and operation reliability of the port. Specifically, the port stability parameter is combined with the port historical power supply mode data for in-depth analysis, and the matching algorithm is used to classify and prioritize the historical power supply behavior of the port, thereby generating power supply priority data. The power supply priority data indicates the importance and priority of the port power supply demand.

[0056] For example, the stability parameter calculated from the load characteristic data of a port is a high stability level, and the historical power supply mode shows that the port is connected to a high-load device. Its power supply priority data is ultimately set to "priority power supply level 1", indicating that its power supply demand should be met first in multi-port devices.

[0057] In step S200, a port load spectrum is generated based on the port power data, and the port load spectrum is calculated to obtain port load balancing data and port load fluctuation data.

[0058] By analyzing and structuring the acquired port power data, a port load map is constructed, which shows the power distribution status of all ports and the relative load conditions between ports. Specifically, the port power data is normalized using mathematical modeling methods to reflect the proportion of actual power usage of different ports to the total power. At the same time, the port load balancing data is calculated in combination with the load distribution to quantitatively evaluate the power distribution balance of each port. In addition, the port power data is dynamically monitored using timing analysis technology to record the changes in port load at different times, thereby calculating the port load fluctuation data to measure load stability and fluctuation range.

[0059] For example, in an 8-port PoE power supply device, the port power data shows that port 1 consumes 35W, and the power consumption of the other ports is 10W. The load map shows that port 1 accounts for 35% of the total power, and the load balance is low. At the same time, through the analysis and recording of fluctuation data, it is found that the power fluctuation range of port 1 is ±5W, while the fluctuation range of other ports is ±1W, indicating that port 1 needs to be optimized.

[0060] The port load balancing data and the power supply priority data are used to generate a port load optimization map, and the port load fluctuation data is mapped using the port load optimization map to obtain the port dynamic adjustment parameters.

[0061] By combining the port load balancing data with the power supply priority data, the power distribution between ports is optimized and modeled, and a port load optimization map is generated. The map focuses on the optimized power distribution strategy and the degree of load balancing between ports. Specifically, in the process of generating the optimization map, the power distribution of ports with higher power supply priority is prioritized, and the ports with lower power supply priority are adjusted to reduce unnecessary power waste. In addition, based on the port load optimization map, it is mapped and analyzed with the port load fluctuation data, and the port dynamic adjustment parameters are extracted and calculated. The parameters are used to guide the real-time adjustment of power distribution to cope with dynamically changing load demands.

[0062] For example, the optimization chart shows that port 1 has the highest power supply priority, and its optimized power is adjusted to 30W, and the power of port 6 with low priority is adjusted from 10W to 5W. At the same time, the mapping of port load fluctuation data shows that port 2 has a fluctuation of more than ±3W, and its dynamic adjustment parameters are recommended to improve power supply stability.

[0063] Instantaneous power calculation is performed on the dynamic adjustment parameters of the ports to obtain the instantaneous power adjustment parameters of the ports, and the initial power allocation parameters of the ports of the multi-port power supply device are optimized by using the instantaneous power adjustment parameters of the ports to obtain the port power allocation strategy.

[0064] By using dynamic adjustment parameters to calculate the instantaneous power of each port, combined with the current port load characteristics and real-time operating status, the port instantaneous power adjustment parameters are generated to accurately reflect the power adjustment requirements of each port in a short period of time. Specifically, the port instantaneous power adjustment parameters are applied to the initial power allocation parameters of the multi-port power supply equipment, and the power allocation strategy of each port is dynamically optimized to achieve the rational use of power supply resources and real-time optimization of power allocation. Finally, a port power allocation strategy that adapts to actual operating conditions is formed to improve the overall power supply efficiency and stability of multi-port equipment.

[0065] For example, during operation, the instantaneous power calculation shows that the instantaneous power demand of port 3 is reduced from 15W to 10W, and the generated instantaneous power adjustment parameter is -5W. After applying this parameter to the initial power allocation parameter, the port power allocation policy will readjust port 3 to 10W and allocate the released 5W to port 7 first to meet its increased instantaneous power demand.

[0066] In step S300, the port power allocation strategy is calculated to obtain a port power threshold and a port safety power range, and the current remaining power data of the port is calculated based on the port power threshold and the port safety power range.

[0067] The port power threshold and port safety power range are determined by analyzing and calculating the port power allocation strategy one by one. Specifically, based on the port load characteristics and power requirements, the basic power allocation parameters of each port are combined with the power dynamic adjustment rules to form the port power threshold. At the same time, the load adaptability of the port is analyzed through historical power behavior and electrical stability data, and the port safety power range is obtained to ensure the safety and stability of power allocation during port operation. Finally, the current remaining power data of each port is calculated based on the port power threshold and the port safety power range.

[0068] For example, in an 8-port power supply device, the basic power allocation parameter of port 1 is 35W, and its power threshold is calculated to be 40W after dynamic adjustment rules. The historical power behavior shows that the fluctuation range of port 1 is within the range of ±5W, and its safe power range is set to 30W-45W. The current remaining power data of the port is obtained by the difference between the actual power allocation and the threshold, showing that the remaining power is 5W.

[0069] The remaining power data is mapped to obtain a port power adjustment factor and a port load adaptation parameter, a power supply control sequence is generated based on the port power adjustment factor, and the port load adaptation parameter is processed using the power supply control sequence to obtain port adjustment data.

[0070] By analyzing the remaining power data in detail and mapping it with the real-time load characteristics of the port, the port power adjustment factor and port load adaptation parameters are calculated. Specifically, the power adjustment factor quantifies the power adjustment range required for the port under the current operating conditions, and the load adaptation parameter provides a guiding value for the adjustment process by analyzing the port load demand and power supply adaptability. Subsequently, a power supply control sequence is generated based on the power adjustment factor, which contains instructions for optimizing power allocation and power supply priority, and the load adaptation parameters are processed to finally form the port adjustment data.

[0071] For example, during the power supply control process, the remaining power data of a port shows a negative power adjustment requirement of -3W, and the mapping generates a power adjustment factor value of -3. At the same time, the load adaptation parameter calculated in combination with the device load demand recommends shutting down low-priority devices. The power supply control sequence includes instructions: shut down the device with a port connection device priority value of 5, and the port adjustment data is processed and applied to the device execution layer.

[0072] Among them, the steps of calculating the port power allocation strategy, obtaining the port power threshold and the port safety power range, and calculating the current remaining power data of the port based on the port power threshold and the port safety power range include: calculating the port power allocation strategy, obtaining the port basic power allocation parameter and the port load adaptation parameter, and generating the port power threshold based on the port basic power allocation parameter.

[0073] The port power threshold is generated by collaboratively analyzing the basic power allocation parameters and the port load adaptation parameters in the port power allocation strategy. Specifically, the basic power allocation parameters indicate the power allocation rules of the port under normal operation, and combined with the port load adaptation parameters, the power adaptability of the port under load fluctuation conditions is evaluated. The port power threshold ensures the rationality and safety of power allocation through comprehensive calculation of the two.

[0074] For example, the basic power allocation parameter of a port is 20 W. The load adaptation parameter shows that its adaptation range is ±5 W. The final generated port power threshold is 25 W.

[0075] The historical power data and instantaneous power data of ports of a multi-port power supply device are obtained, and the historical power data of the ports are analyzed to obtain the port power trend data and the port power fluctuation data.

[0076] Through in-depth analysis of the port historical power data recorded during the long-term operation of the equipment, combined with the port instantaneous power data, the port power distribution and fluctuation behavior are modeled and analyzed to generate port power trend data and port power fluctuation data. Specifically, the power trend data shows the long-term change law and growth trend of the port power, while the power fluctuation data quantifies the power fluctuation amplitude and dynamic behavior of the port in a short period of time.

[0077] For example, by analyzing the historical power data of the port, it is shown that the long-term power trend of port 1 is gradually increasing from 15W to 30W, and the power fluctuation data analysis shows that the power fluctuation range in a short period of time is ±2W.

[0078] The port power trend data and the port load adaptation parameter are used to calculate the port safety power range, and the port power threshold is adjusted based on the port power fluctuation data to obtain the corrected port power threshold.

[0079] By combining the port power trend data and the port load adaptation parameters, the power range is dynamically evaluated and set to generate a port safety power range. Specifically, the power trend data provides a reference for port power changes, while the load adaptation parameters quantify the port's ability to withstand dynamic load conditions. At the same time, based on the power fluctuation data, the power threshold is adjusted to cope with the change trend, and finally a revised port power threshold is generated.

[0080] For example, the port trend data shows that the power gradually increases to 50W, the load adaptation parameter is ±10W, and the safe power range is set to 40W-60W. Combined with the fluctuation data, it is found that the power surges to 65W in a short period of time. After adjustment, the correction threshold is set to 60W.

[0081] The corrected port power threshold is applied to calculate the instantaneous power data of the port to obtain the instantaneous remaining power data of the port, and the port safety power range is used to process the instantaneous remaining power data of the port to obtain the long-term remaining power data of the port and the port power supply adjustment factor.

[0082] By applying the corrected power threshold to the instantaneous power data of the port, the instantaneous remaining power data is generated, and the current power usage of the port and the margin within the safe range are analyzed. Specifically, the instantaneous remaining power data is combined with the safe power range, and long-term data processing is performed on it to obtain the long-term remaining power data of the port, and the port power supply adjustment factor is generated to guide the direction and rules of dynamic power adjustment.

[0083] For example, the instantaneous power data of the port shows that the power consumption is 45W, the correction threshold is 50W, and the calculated instantaneous remaining power data is 5W. Combined with the data processing within the safety range, the long-term remaining power data is generated as 7W, and the power supply adjustment factor recommends increasing the power allocation of high-priority devices.

[0084] A port power adjustment sequence is generated based on the long-term remaining power data of the port, and the port power adjustment sequence is optimized using the port power supply adjustment factor to obtain the current remaining power data of the port.

[0085] By dynamically adjusting the long-term remaining power data, a port power adjustment sequence is generated, which records the real-time power allocation and the adjustment rules of the remaining power, and optimizes the power adjustment sequence in combination with the power supply adjustment factor to ensure the rationality and priority of power adjustment. The final port current remaining power data reflects the actual power margin after the power allocation of each port.

[0086] For example, the power supply adjustment factor recommends reducing the power consumption in the port power allocation strategy to release resources. After optimizing the port adjustment sequence, the current remaining power data of the port shows that the remaining power of port 5 has increased by 10W.

[0087] In step S400, the port power allocation strategy is optimized using the port adjustment data to obtain an optimized port power allocation strategy, the abnormal ports of the multi-port power supply device are detected using the optimized port power allocation strategy, and port power supply deviation data and port abnormality identification data are generated based on the detection results.

[0088] By combining the port adjustment data with the original power allocation strategy, the power allocation rules of each port are adjusted using a dynamic optimization algorithm to generate an optimized port power allocation strategy. Specifically, according to the power demand changes and load priority adjustment information recorded in the port adjustment data, power resources are reallocated to optimize the power supply balance between ports. Subsequently, the optimized power allocation strategy is used to detect power supply anomalies on all ports. The detection process analyzes the power deviation of each port and generates port power supply deviation data. The abnormal ports are further identified based on the power supply deviation data to form port anomaly identification data and locate the cause of the power supply anomaly.

[0089] For example, during device operation, the port adjustment data shows that the actual power demand of port 6 has increased from 20W to 35W. The optimized power allocation strategy promptly transfers power from low-priority ports to port 6 to ensure that it has sufficient power. However, the power supply detection shows that port 3 has insufficient power output (actual power 10W, target power 15W). The power supply deviation data records this anomaly, and the anomaly identification data shows that the load fluctuation of the device connected to port 3 exceeds the standard range.

[0090] The port abnormality identification data is mapped based on the port power supply deviation data to obtain abnormal port failure mode data, and the abnormal port failure mode data is calculated to obtain the port power supply adjustment parameter and the port recovery strategy.

[0091] By analyzing the power supply deviation data and the abnormal identification data, the fault mode mapping of the abnormal port is established, and the abnormal port fault mode data is generated. Specifically, the abnormal port fault mode data is classified and labeled according to the abnormal type (such as short circuit, low voltage, etc.) and the fault law. Subsequently, the corresponding port power supply adjustment parameters and port recovery strategies are calculated based on the fault mode. The port power supply adjustment parameters are used to adjust the power output of the abnormal port, and the recovery strategy provides clear operation guidance to quickly repair the fault.

[0092] For example, the port abnormality identification data shows that port 7 has intermittent power outages, and combined with the power supply deviation data analysis, the port load short circuit abnormality is found. The fault mode data records the characteristics of the short circuit behavior, and the adjustment parameters are calculated to generate a recommendation to temporarily reduce the port power output to 0W. At the same time, the recovery strategy indicates to check the connected equipment and replace the damaged load module.

[0093] The target port is powered on using the port power adjustment parameters to obtain the port power data, and the abnormal port is powered on using the port recovery strategy to obtain the port power status data; the target port is a port that meets the preset port power optimization conditions; the abnormal port is a port where power abnormality is detected or the load fluctuation exceeds the preset threshold.

[0094] By applying the power supply adjustment parameters, the target port is adjusted in real time to gradually restore the normal operation of the target port. Specifically, according to the power supply optimization conditions, the target port is adjusted to increase or decrease the voltage or limit the power. At the same time, the abnormal port takes remedial measures (such as temporary isolation or degradation) according to the recovery strategy, corrects and restores its power supply, and generates updated port power supply status data, which reflects the power supply recovery process and results.

[0095] For example, in the case of short-term power shortage of port 5 (current power 15W, target power 20W), the power adjustment parameters indicate that the power should be increased to 20W. After the adjustment is completed, the port power data shows that it has returned to normal. In the case of abnormal load overload of port 8, the recovery strategy indicates to disconnect the device and reset the port power allocation. Finally, the power supply status data shows that port 8 has returned to no-load operation.

[0096] In step S500, the port power data is calculated to obtain a port power stability parameter and a port power supply fluctuation parameter, and a local power supply balancing factor is calculated based on the port power stability parameter and the port power supply fluctuation parameter.

[0097] By analyzing the timing characteristics and dynamic fluctuations in the port power data, the power stability parameters and power supply fluctuation parameters of the port are extracted using statistical and computational algorithms. Specifically, the power stability parameter evaluates the continuity and stability of power by calculating the mean and standard deviation of the port power data; the power supply fluctuation parameter measures the dynamic change amplitude of power output by measuring the peak and trough amplitude and frequency characteristics of the port power data. Subsequently, the power stability parameter and the power supply fluctuation parameter are input into the balancing model, and weighted calculation is performed in combination with the correlation between ports to obtain the local power supply balancing factor, which is used to quantify and guide the optimization of local power supply.

[0098] For example, in a multi-port device, the power stability parameter calculation of port 1 shows a standard deviation of 0.5W, indicating stable power output, while the power supply fluctuation parameter shows a fluctuation amplitude of 2W and a fluctuation frequency of 3 times per minute. Combined with other port-related parameters, the local balancing factor calculation shows that port 1 has a lower adjustment priority.

[0099] The port power supply status data is calculated to obtain the port load distribution data and the port power supply utilization data, and the global power supply adaptation parameters are calculated using the port load distribution data and the port power supply utilization data.

[0100] By performing multi-dimensional analysis on the port power supply status data, port load distribution data and port power supply utilization data are generated. Specifically, the load distribution data constructs an overall load distribution diagram by counting the power demand ratio of each port; the power supply utilization data evaluates the utilization efficiency of device resources by calculating the ratio of the actual power of the port to its power supply capacity. By cross-analyzing the load distribution data and the power supply utilization data, the global power supply adaptation parameter is calculated, which reflects the overall power supply efficiency and resource matching of the multi-port device and is used to adjust the global power supply strategy.

[0101] For example, in a certain operation scenario, the port power supply status data shows that the load distribution of the eight ports is 10%, 15%, 20%, etc., and the overall load diagram shows that port 2 and port 3 are the main power consumption ports. However, the utilization analysis shows that the actual utilization of port 3 is 90%, and port 5 is only 50%. Through the calculation of power supply adaptation parameters, it is recommended to transfer some low-priority loads to port 5.

[0102] The local power supply balancing factor and the global power supply adaptation parameter are used to generate the global power supply balancing parameter, and the global power supply balancing parameter is used to optimize the power supply strategy of the multi-port power supply device to obtain the optimized power supply control scheme.

[0103] By integrating the local power balancing factor and the global power adaptation parameter, a global power balancing parameter is generated, which uniformly measures the local and global power supply status, and constrains and adjusts it in the optimization model to formulate an optimized power supply control strategy. Specifically, the power supply strategy optimization process focuses on balancing the power distribution between ports, improving the overall power supply stability and utilization efficiency, while ensuring that high-priority load demands are met first. Finally, an optimized power supply control scheme is formed to guide the operation adjustment of the equipment.

[0104] For example, the global power balancing parameter optimization strategy shows that it is recommended to increase the power of port 1 from 20W to 25W to support higher priority devices, and reduce port 6 from 15W to 10W to release power resources for other high-load ports. The final optimized power supply control solution achieves efficient matching of device resources and improves overall stability.

[0105] By collecting the port voltage data and port current data of the multi-port power supply equipment, and performing time-series sampling and dynamic change analysis on them, the port current change sequence and port voltage change sequence are generated, and the port power data and port electrical stability data are further calculated. By mapping the port electrical stability data, the port load status data is generated, and the port power data is obtained by correlation analysis combined with the port power data. Based on the port status data and power data, the port operation sequence is constructed, and the port load characteristic data and the port historical power supply mode data are extracted by mapping. Subsequently, the port stability parameters are obtained by calculating the port load characteristic data, so as to optimize the port historical power supply mode data and generate the power supply priority data, providing a basis for port power management. The port load map is generated by using the port power data, and the port load balancing data and port load fluctuation data are obtained by calculation, and the port load optimization map is further generated in combination with the power supply priority data. The port dynamic adjustment parameters are obtained by mapping the port load fluctuation data, and the instantaneous power adjustment parameters are calculated to optimize the power allocation strategy of the multi-port power supply equipment. The port power allocation strategy is calculated to generate the port power threshold and the safe power range, and the historical and instantaneous power data are analyzed at the same time to generate the corrected port power threshold and the remaining power data. Based on the remaining power data, the port adjustment parameters and power supply control sequence are optimized, and the fault mode data, adjustment parameters and recovery strategies are generated for abnormal ports to dynamically optimize the power supply status. Finally, by calculating the local power supply balancing factor and the global adaptation parameters, the global power supply balancing parameters are generated to optimize the power supply strategy, forming an optimized power supply control scheme with high efficiency, stability and flexibility, realizing the precise management, dynamic adjustment and fault recovery of power distribution between ports, and effectively improving the overall performance and resource utilization of multi-port power supply equipment.
