As a technology that can transmit data and electrical energy simultaneously in a single network data cable, PoE (Power over Ethernet) has been widely used in fields such as video surveillance, wireless access points (APs), and smart homes. Due to its high efficiency and convenience, multi-port PoE power supply devices have gradually become an important device form in the market.

[0027] The following will further illustrate the technical solutions of the present invention with reference to the accompanying drawings and through specific implementation manners.

[0028] Embodiment 1:

[0029] Embodiment 1:

[0030] As Figure 1 shown, this application provides a multi-port POE power supply method, including steps S100 to S500.

[0031] Step S100, collect the port power supply parameters of the multi-port power supply device, perform data processing on the port power supply parameters, and obtain the port power data and the power supply priority data.

[0032] In this step, the port power supply parameters of each port of the multi-port power supply device are collected in sequence, including information such as the current, voltage, and load type of each port, and the collected data is parsed and calculated through a data processing algorithm. Specifically, the processing algorithm operates on 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.

[0033] For example, in practical applications, for an 8-port PoE power supply device, the collected port power supply parameters include a current value of 0.3A - 0.8A and a voltage value of 48V for each port. Through calculation, the power range for each port can be obtained as 14.4W - 38.4W, and priority data is allocated according to the type of port load (such as cameras, APs, etc.).

[0034] 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.

[0035] In this step, by visualizing the port power data calculated in step S100, a port load map for each port is generated. This map shows the power requirements 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 requirements of high-priority ports are preferentially met in the strategy.

[0036] For example, in a monitoring system, port 1 is connected to a high-power infrared camera, and ports 2 - 4 are connected to ordinary cameras. Using the port load map, it can be observed that the power requirement of port 1 is higher than that of other ports. By mapping the power supply priority data, the allocation strategy will preferentially meet the power requirement of port 1.

[0037] 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.

[0038] In this step, based on the port power allocation strategy, the maximum power allocation upper limit for each port, that is, the port power threshold, is calculated, and the total remaining power data of the multi-port power supply device is calculated. Specifically, according to the port power threshold and the remaining power data, a power supply control sequence is generated. This sequence contains instructions for adjusting the power of each port. Subsequently, the port adjustment data is generated by parsing the power supply control sequence. The port adjustment data contains specific port adjustment schemes, such as reducing power, shutting down low-priority ports, etc.

[0039] For example, assume that the total power of the device is 100W. The port power allocation strategy determines that port 1 is 38.4W, and ports 2 - 4 are each 14.4W. The total demand is 81.6W, and the remaining power is 18.4W. If a device with a load of 15W needs to be turned on at port 5, the port adjustment data will release power resources by shutting down the low-priority port 4.

[0040] Step S400: Optimize the port power allocation strategy according to the port adjustment data to obtain an optimized port power allocation strategy, and use the optimized port power allocation strategy to detect the abnormal ports of the multi-port power supply device to obtain port power data and port power supply status data.

[0041] In this step, optimize the port power allocation strategy according to the port adjustment data, update the power allocation rules to improve power supply adaptability, and at the same time, use the optimized port power allocation strategy to detect the power supply status of each port in real time, focusing on monitoring the power data fluctuations and power supply abnormalities of abnormal ports. Specifically, the anomaly detection algorithm compares the port power data and the power supply status data to quickly locate the abnormal ports.

[0042] For example, during the operation of a certain device, the power of port 2 surges due to a load short circuit. The optimized port power allocation strategy detects this anomaly in a timely manner and automatically isolates port 2 to ensure normal power supply to other ports.

[0043] Step S500: Calculate the port power data and the port power supply status data to obtain the global power supply balance parameter, and use the global power supply balance parameter to optimize the control of the power supply of the multi-port power supply device.

[0044] In this step, generate the global power supply balance parameter by summarizing and calculating the port power data and the port power supply status data of all ports. 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.

[0045] For example, in a power supply device, the global power supply balance parameter can reflect the impact of excessive power supply demand at a certain port on the overall power supply. The device adjusts the power supply power of low-priority ports according to the parameter to balance the power distribution among ports.

[0046] In this embodiment, by collecting the port power supply parameters of the multi-port power supply device and processing the port power supply parameters, port power data and power supply priority data are generated. Then, based on the port power data, a port load map is generated, and a port power allocation strategy is obtained by mapping the port load map and the power supply priority data. Further, the port power allocation strategy is calculated to obtain a port power threshold and remaining power data, and a power supply control sequence is generated based on the port power threshold and the remaining power data. Finally, 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, thereby obtaining port power data and port power supply status data, and calculating global power supply balance parameters from them. Finally, the power supply of the multi-port power supply device is optimized and controlled using the global power supply balance parameters. This realizes efficient power allocation and power supply management of the multi-port power supply device, optimizes the port power allocation strategy, and improves the power supply efficiency. The innovation lies in generating a power supply control sequence and detecting abnormal ports in real time based on this sequence to ensure the overall performance and stability of the power supply device. In addition, by obtaining the global power supply balance parameters, the problem of low power supply efficiency caused by dynamic changes in port loads and abnormal ports is effectively solved, thereby realizing precise control and maximizing the utilization of resources of the multi-port power supply device, and improving the problems of uneven power distribution, low power supply efficiency, and untimely identification of abnormal ports when port loads change dynamically or the device is abnormal.

[0047] Embodiment 2:

[0048] In step S100, the port power supply parameters of the multi-port power supply device are collected, where the port power supply parameters include port voltage data and port current data.

[0049] The port voltage data and port current data are collected by sampling each port of the multi-port power supply device one by one. Specifically, a high-precision sampling circuit is used to collect the port voltage value and port current value in real time, and the collected data is preliminarily filtered to remove interference noise. At the same time, a timing sampling technique is adopted to record the voltage change and current change of each port to construct a port current change sequence and a port voltage change sequence. These sequences contain the electrical characteristic information of the port. Further, the port current change sequence and the port voltage change sequence are calculated using the power calculation formula to obtain 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 amplitude of electrical state fluctuations.

[0050] For example, in practical 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 technique, 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 the voltage and current, the port electrical stability data can be determined, such as whether there are short-term current fluctuations or voltage drops exceeding the threshold at the port.

[0051] Perform timing sampling on the port voltage data and port current data, and based on the sampling results, construct the port current change sequence and port voltage change sequence. Calculate the port current change sequence and port voltage change sequence to obtain the port power data and port electrical stability data.

[0052] Through comparative analysis of the port electrical stability data, combine the stability data with the load type and port usage records of the multi-port power supply device. Specifically, conduct a detailed evaluation of the port electrical stability data in combination with the demand characteristics of the load device to construct a stability curve, and perform data mapping on the port electrical stability data to generate port load status data. The port load status data can comprehensively characterize the power supply load situation and power supply change trend of each port.

[0053] For example, during the generation process of the port load status data, if the port electrical stability data detects that the fluctuation range of the port current exceeds the set threshold (such as ±0.5A) within a short period of time, it is determined that the load status of this port is unstable and is affected by non-standard devices or overload conditions. Through data mapping processing, the results reflecting the port electrical fluctuation situation and the real-time load status can be obtained in the port load status data.

[0054] Map the port electrical stability data to obtain the port load status data, and use the port load status data to conduct correlation analysis on the port power data to obtain the port status data.

[0055] Through data structuring processing of the port electrical stability data, map the port electrical stability data to the port load status data. The mapping process includes stability value classification and load status marker generation. Specifically, in combination with the operating environment and load type of the port, quantify the characteristics of the port electrical stability data and label the load status categories of each port, such as "light load", "medium load", "heavy load", etc. At the same time, through an algorithm, combine the port load status data with the port power data for correlation analysis, thereby generating the port status data, which comprehensively reflects the real-time load situation and stability of the port.

[0056] For example, in an actual scenario, the electrical stability data of a certain port shows that the voltage change range is within 0.5V and the current fluctuation is ±0.1A. After mapping, "stable - medium load" load status data is generated. Through correlation analysis, the power data of this port is matched and supplemented into the port status data, showing that the power consumption is 24W and the electrical fluctuation is stable.

[0057] Generate a port operation sequence based on the port power data and port status data, and use the port operation sequence to map the port status data to obtain port load characteristic data and port historical power supply mode data.

[0058] Through time - series analysis of the port power data and port status data, integrate the real - time operation information of the port into a port operation sequence. The port operation sequence records the state change trend of each port at different time periods. Specifically, use a mapping algorithm to dynamically map the port operation sequence and port status data 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, through historical data comparison and analysis of the port operation sequence, extract the port historical power supply mode data to depict the power supply behavior and characteristic mode of the port.

[0059] For example, within a cycle, the operation sequence of a certain 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 amplitude 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 demands.

[0060] Calculate the port load characteristic data to obtain port stability parameters, and based on the port stability parameters, process the port historical power supply mode data to obtain power supply priority data.

[0061] By calculating the fluctuation characteristics, load trend, and load balance in the port load characteristic data, generate port stability parameters, which quantitatively describe the load stability and operation reliability of the port. Specifically, conduct in - depth analysis by combining the port stability parameters and port historical power supply mode data, and use a matching algorithm to classify and determine the priority of the port's historical power supply behavior, thereby generating power supply priority data. The power supply priority data indicates the importance and priority guarantee of the port's power supply demand.

[0062] For example, the stability parameter calculated from the load characteristic data of a certain port is at a high - stability level, and the historical power supply mode shows that this port is connected to high - load devices. Its power supply priority data is finally set to "priority power supply level 1", indicating that its power supply demand should be preferentially met among multi - port devices.

[0063] In step S200, a port load map is generated based on the port power data, and the port load map is calculated to obtain port load balance data and port load fluctuation data.

[0064] By analyzing and structuring the obtained port power data, a port load map is constructed, which shows the power distribution status of all ports and the relative load conditions among ports. Specifically, using mathematical modeling methods, the port power data is normalized to reflect the proportion of the actual power usage of different ports to the total power. At the same time, the port load balance 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 time series analysis techniques, and the changes in port load at different times are recorded, so as to calculate the port load fluctuation data, which is used to measure the load stability and fluctuation range.

[0065] 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 remaining ports is 10W each. Through the load map, it can be known that port 1 accounts for 35% of the total power, and the load balance is relatively low. At the same time, through the analysis and recording of the fluctuation data, it is found that the power fluctuation range of port 1 is ±5W, while that of other ports is ±1W, indicating that port 1 needs to be optimized.

[0066] A port load optimization map is generated using the port load balance data and the power supply priority data, and the port load optimization map is used to map the port load fluctuation data to obtain port dynamic adjustment parameters.

[0067] By combining the port load balance data and the power supply priority data, an optimization model for power distribution among ports is established to generate a port load optimization map, which mainly shows the optimized power distribution strategy and the load balance degree among ports. Specifically, in the process of generating the optimization map, ports with higher power supply priority are guaranteed their power distribution first, and 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. This parameter is used to guide the real-time adjustment of power distribution to meet the dynamically changing load requirements.

[0068] For example, the optimization map shows that the power supply priority of port 1 is the highest, and its optimized power is adjusted to 30W. The power of port 6 with low priority is adjusted from 10W to 5W. At the same time, the mapping of the port load fluctuation data shows that port 2 needs to improve its power supply stability because its fluctuation exceeds ±3W.

[0069] The instantaneous power of the port dynamic adjustment parameter is calculated to obtain the port instantaneous power adjustment parameter, and the initial power distribution parameter of the port of the multi-port power supply device is optimized by using the port instantaneous power adjustment parameter to obtain the port power distribution strategy.

[0070] By using the dynamic adjustment parameter to calculate the instantaneous power of each port, combining the current port load characteristics and real-time operating status, the port instantaneous power adjustment parameter is generated to accurately reflect the power adjustment requirements of each port in a short time. Specifically, the port instantaneous power adjustment parameter is applied to the initial power distribution parameter of the multi-port power supply device, and the power distribution strategy of each port is dynamically optimized to realize the rational utilization of power supply resources and the real-time optimization of power distribution. Finally, a port power distribution strategy adapted to the actual operating conditions is formed to improve the overall power supply efficiency and stability of the multi-port device.

[0071] For example, during operation, it is known through instantaneous power calculation that the instantaneous power demand of port 3 decreases from 15W to 10W, and the generated instantaneous power adjustment parameter is -5W. After applying this parameter to the initial power distribution parameter, the port power distribution strategy will readjust port 3 to 10W and preferentially allocate the released 5W to port 7 to meet its increased instantaneous power demand.

[0072] In step S300, the port power distribution strategy is calculated to obtain the port power threshold and the port safe power range, and the current remaining power data of the port is calculated based on the port power threshold and the port safe power range.

[0073] By analyzing and calculating the port power distribution strategy one by one, the port power threshold and the port safe power range are determined. Specifically, based on the port load characteristics and power demand, the basic power distribution parameter of each port is combined with the power dynamic adjustment rule to form the port power threshold. At the same time, through historical power behavior and electrical stability data, the load adaptation ability of the port is analyzed to obtain the port safe power range to ensure the safety and stability of power distribution during the operation of the port. Finally, according to the port power threshold and the port safe power range, the current remaining power data of each port is calculated.

[0074] For example, in an 8-port power supply device, the basic power distribution parameter of port 1 is 35W, and its power threshold is calculated to be 40W through dynamic adjustment rule calculation. The historical power behavior shows that the fluctuation range of port 1 is within ±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 distribution and the threshold, showing a remaining power of 5W.

[0075] Map the remaining power data to obtain the port power adjustment factor and the port load adaptation parameter. Generate a power supply control sequence based on the port power adjustment factor, and use the power supply control sequence to process the port load adaptation parameter to obtain the port adjustment data.

[0076] By analyzing the remaining power data in detail, mapping it to the real-time port load characteristics, the port power adjustment factor and the port load adaptation parameter are calculated. Specifically, the power adjustment factor quantifies the range of power adjustment required by 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 the power supply adaptation ability. Subsequently, a power supply control sequence is generated based on the power adjustment factor, which contains instructions for optimizing power distribution and power supply priority, and processes the load adaptation parameter to finally form the port adjustment data.

[0077] For example, during the power supply control process, the remaining power data of a certain port shows that the negative power adjustment demand is -3W. The mapped power adjustment factor value is -3. At the same time, combined with the device load demand, the load adaptation parameter is calculated to suggest turning off low-priority devices. The power supply control sequence contains the instruction: turn off the device with a priority value of 5 connected to the port. The port adjustment data is processed and applied to the device execution layer.

[0078] Among them, the steps of calculating the port power distribution strategy to obtain the port power threshold and the port safe power range, and calculating the current remaining power data of the port based on the port power threshold and the port safe power range include: calculating the port power distribution strategy to obtain the port basic power distribution parameter and the port load adaptation parameter, and generating the port power threshold based on the port basic power distribution parameter.

[0079] Generate the port power threshold through the collaborative analysis of the basic power distribution parameter and the port load adaptation parameter in the port power distribution strategy. Specifically, the basic power distribution parameter indicates the power distribution rule of the port under normal operating conditions. Combining the port load adaptation parameter, the power adaptability of the port under load fluctuation conditions is evaluated. The port power threshold is calculated through the comprehensive calculation of the two to ensure the rationality and safety of power distribution.

[0080] For example, the basic power distribution parameter of a certain port is 20W, and its adaptation range shown by the load adaptation parameter is ±5W. The finally generated port power threshold is 25W.

[0081] Obtain the port historical power data and the port instantaneous power data of the multi-port power supply device, and perform data analysis on the port historical power data to obtain the port power trend data and the port power fluctuation data.

[0082] By deeply analyzing the historical power data of the port recorded during the long-term operation of the device, combining it with the instantaneous power data of the port, modeling and analyzing the power distribution and fluctuation behavior of the port, power trend data and port power fluctuation data are generated. 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.

[0083] For example, by analyzing the historical power data of the port, it shows 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 amplitude within a short period of time is ±2W.

[0084] Calculate the port safety power range using the port power trend data and port load adaptation parameters, and adjust the port power threshold based on the port power fluctuation data to obtain the corrected port power threshold.

[0085] By combining the port power trend data with the port load adaptation parameters, dynamically evaluate and set the power range to generate the port safety power range. Specifically, the power trend data provides a reference basis for the change of port power, while the load adaptation parameters quantify the bearing capacity of the port under dynamic load conditions. At the same time, based on the power fluctuation data, adjust the power threshold to cope with the change trend, and finally generate the corrected port power threshold.

[0086] For example, the port trend data shows that the power gradually increases to 50W, the load adaptation parameter is ±10W, and the safety power range is set to 40W - 60W. Combining the fluctuation data, it is found that the short-term power surges to 65W, and after adjustment, the corrected threshold is set to 60W.

[0087] Calculate the port instantaneous remaining power data using the corrected port power threshold for the port instantaneous power data, and process the port instantaneous remaining power data using the port safety power range to obtain the port long-term remaining power data and the port power supply adjustment factor.

[0088] By applying the corrected power threshold to the calculation of the port instantaneous power data, generate the instantaneous remaining power data, and analyze the current power usage of the port and the margin within the safety range. Specifically, combine the instantaneous remaining power data with the safety power range and perform long-term data processing on it to obtain the port long-term remaining power data, and at the same time generate the port power supply adjustment factor to guide the direction and rules of dynamic power adjustment.

[0089] For example, the port instantaneous power data shows that the power consumption is 45W, the corrected threshold is 50W, and the calculated instantaneous remaining power data is 5W. Combining the data processing within the safety range, generate the long-term remaining power data of 7W, and at the same time the power supply adjustment factor recommends increasing the power allocation of high-priority devices.

[0090] Generate a port power adjustment sequence based on the long-term remaining power data of the port, and optimize the port power adjustment sequence using the port power supply adjustment factor to obtain the current remaining power data of the port.

[0091] By dynamically adjusting the long-term remaining power data, a port power adjustment sequence is generated. This sequence records the adjustment rules of real-time power distribution and remaining power, and combines the power supply adjustment factor to optimize the power adjustment sequence to ensure the rationality and priority of power adjustment. The finally formed current remaining power data of the port reflects the actual power margin after power distribution for each port.

[0092] For example, the power supply adjustment factor suggests reducing power consumption in the port power distribution 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.

[0093] In step S400, use the port adjustment data to optimize the port power distribution strategy to obtain the optimized port power distribution strategy. Use the optimized port power distribution strategy to detect the abnormal ports of the multi-port power supply device, and generate port power supply deviation data and port abnormal identification data based on the detection results.

[0094] By combining the port adjustment data with the original power distribution strategy, use a dynamic optimization algorithm to adjust the power distribution rules of each port, thereby generating an optimized port power distribution strategy. Specifically, according to the power demand changes and load priority adjustment information recorded in the port adjustment data, reallocate power resources to optimize the power supply balance between ports. Subsequently, use the optimized power distribution strategy to detect power supply abnormalities for all ports. The detection process analyzes the power deviation of each port to generate port power supply deviation data, and further identifies abnormal ports based on the power supply deviation data to form port abnormal identification data and locate the cause of power supply abnormalities.

[0095] For example, during device operation, it is known from the port adjustment data that the actual power demand of port 6 has increased from 20W to 35W. The optimized power distribution strategy promptly transfers power from low-priority ports to port 6 to ensure sufficient power. The power supply detection shows that there is a problem of insufficient power output at port 3 (actual power 10W, target power 15W). The power supply deviation data records this abnormality, and the abnormal identification data shows that the load fluctuation of the device connected to port 3 exceeds the standard range.

[0096] Map the port abnormal identification data based on the port power supply deviation data to obtain abnormal port fault mode data, and calculate the abnormal port fault mode data to obtain port power supply adjustment parameters and port recovery strategies.

[0097] By analyzing the power supply deviation data and anomaly recognition data, a fault mode mapping of the abnormal ports is established to generate the fault mode data of the abnormal ports. Specifically, the fault mode data of the abnormal ports are classified and labeled according to the anomaly type (such as short circuit, low voltage, etc.) and the fault pattern. 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 ports, and the recovery strategy provides clear operation guidance for quickly repairing the faults.

[0098] For example, the port anomaly recognition data shows that there is intermittent power outage at port 7. By analyzing the power supply deviation data, it is found that the port has a short circuit anomaly in the load. The fault mode data records the characteristics of the short circuit behavior. By calculation, the adjustment parameter is generated to temporarily reduce the port power output to 0W. At the same time, the recovery strategy instructs to check the connected devices and replace the damaged load module.

[0099] The power of the target port is adjusted using the port power supply adjustment parameters to obtain the port power data, and the power supply of the abnormal port is restored using the port recovery strategy to obtain the port power supply status data. Among them, the target port is the port that meets the preset port power supply optimization conditions; the abnormal port is the port where the detected power anomaly or load fluctuation exceeds the preset threshold.

[0100] By applying the power supply adjustment parameters to perform real-time power adjustment on the target port, the normal operating state of the target port is gradually restored. Specifically, according to the power supply optimization conditions, adjustment operations such as boosting, bucking, or power limiting are performed on the target port. At the same time, the abnormal port takes remedial measures (such as temporary isolation or downgrading) according to the recovery strategy to correct and restore its power supply, generating updated port power supply status data, which reflects the power supply recovery process and results.

[0101] For example, for the situation of short-term power shortage at port 5 (current power 15W, target power 20W), the power supply adjustment parameter indicates to increase the power to 20W. After the adjustment, the port power data shows that it has returned to normal. For the abnormal situation of port 8 due to overloaded load, the recovery strategy instructs to disconnect the device connection and reset the port power distribution. Finally, the power supply status data shows that port 8 has returned to no-load operation.

[0102] In step S500, the port power data is calculated to obtain the port power stability parameter and the port power supply fluctuation parameter, and the local power supply balance factor is calculated based on the port power stability parameter and the port power supply fluctuation parameter.

[0103] By analyzing the timing characteristics and dynamic fluctuations in port power data, statistical and computational algorithms are used to extract the power stability parameters and power supply fluctuation parameters of the ports respectively. Specifically, the power stability parameters are obtained by calculating the mean and standard deviation of the port power data to evaluate the persistence and stability of the power; the power supply fluctuation parameters are obtained by measuring the peak-to-valley amplitude and frequency characteristics of the port power data to measure the dynamic change range of the power output. Subsequently, the power stability parameters and power supply fluctuation parameters are input into the equilibrium model, and weighted calculations are performed in combination with the correlation between ports to obtain the local power supply equilibrium factor, which is used to quantify and guide local power supply optimization.

[0104] For example, in a multi-port device, the calculation of the power stability parameters of port 1 shows that the standard deviation is 0.5W, indicating stable power output, while the power supply fluctuation parameters show that the fluctuation amplitude is 2W and the fluctuation frequency is 3 times per minute. Combining the relevant parameters of other ports, the calculation of the local equilibrium factor shows that the adjustment priority of port 1 is relatively low.

[0105] Calculations are performed on the port power supply status data to obtain the port load distribution data and the port power supply utilization rate data, and the global power supply adaptation parameters are calculated using the port load distribution data and the port power supply utilization rate data.

[0106] Through multi-dimensional analysis of the port power supply status data, the port load distribution data and the port power supply utilization rate data are generated. Specifically, the load distribution data is obtained by statistically analyzing the proportion of power demand of each port to construct an overall load distribution map; the power supply utilization rate data is obtained by calculating the ratio of the actual power of the port to its power supply capacity to evaluate the utilization efficiency of the device resources. By cross-analyzing the load distribution data and the power supply utilization rate data, the global power supply adaptation parameters are calculated, which reflect the overall power supply efficiency and resource matching of the multi-port device and are used to adjust the global power supply strategy.

[0107] For example, in a certain operating scenario, the port power supply status data shows that the load distributions of 8 ports are 10%, 15%, 20%, etc. respectively, and the overall load map shows that ports 2 and 3 are the main power consumption ports. The utilization rate analysis shows that the actual utilization rate of port 3 is 90% and that of port 5 is only 50%. The power supply adaptation parameter calculation suggests transferring some low-priority loads to port 5.

[0108] The global power supply equilibrium parameters are generated using the local power supply equilibrium factor and the global power supply adaptation parameters, and the power supply strategy of the multi-port power supply device is optimized using the global power supply equilibrium parameters to obtain an optimized power supply control scheme.

[0109] By comprehensively integrating the local power supply balance factor and the global power supply adaptation parameter, a global power supply balance parameter is generated. This parameter uniformly measures the local and global power supply states and is constrained and adjusted 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, and ensuring the priority satisfaction of high-priority load requirements. Finally, an optimized power supply control scheme is formed to guide the operation adjustment of the device.

[0110] For example, the optimization strategy based on the global power supply balance parameter shows that it is recommended to increase the power of port 1 from 20W to 25W to support higher-priority devices, while reducing the power of port 6 from 15W to 10W to release power resources to other high-load ports. The finally optimized power supply control scheme realizes the efficient matching of device resources and the improvement of overall stability.

[0111] By collecting the port voltage data and port current data of the multi-port power supply device, and performing time-series sampling and dynamic change analysis on them, a port current change sequence and a port voltage change sequence are generated. Further, the port power data and port electrical stability data are calculated. By mapping the port electrical stability data, the port load status data is generated, and through correlation analysis with the port power data, the port status data is obtained. Based on the port status data and power data, a port operation sequence is constructed, and the port load characteristic data and port historical power supply mode data are extracted through mapping. Subsequently, the port stability parameter is obtained by calculating the port load characteristic data, and the port historical power supply mode data is optimized with this to generate the power supply priority data, providing a basis for port power management. The port load map is generated using the port power data, and the port load balance data and port load fluctuation data are calculated. Further, the port load optimization map is generated by combining the power supply priority data. The port dynamic adjustment parameter is obtained by mapping the port load fluctuation data, and the instantaneous power adjustment parameter is calculated to optimize the power distribution strategy of the multi-port power supply device. The port power distribution strategy is calculated to generate the port power threshold and the safe power range, and at the same time, the historical and instantaneous power data are analyzed to generate the corrected port power threshold and the remaining power data. Based on the remaining power data, the port adjustment parameter and the power supply control sequence are optimized, and the fault mode data, adjustment parameter, and recovery strategy are generated for the abnormal port to dynamically optimize the power supply state. Finally, by calculating the local power supply balance factor and the global adaptation parameter, a global power supply balance parameter is 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 the power distribution between ports, and effectively improving the overall performance and resource utilization rate of the multi-port power supply device.
