[0018] like Figure 1 As shown, the power system 10 includes a power supply device 100 for supplying power to the target, a data acquisition circuit 200, and a detection device 300.

[0019] The acquisition circuit 200 is located between the power supply device 100 and the target power supply to acquire the actual output inductance value, actual feedback voltage value, actual output voltage value and actual overcurrent protection value of the corresponding power supply device 100.

[0020] Optionally, in one embodiment of this application, the acquisition circuit 200 includes: at least one inductance detection circuit, at least one feedback voltage detection circuit, at least one output voltage detection circuit, and at least one output current detection circuit.

[0021] At least one inductance detection circuit is used to receive the analog inductance signal of the power supply device 100 and determine the digital inductance signal of the power supply device 100 based on the analog inductance signal, so as to determine the actual output inductance value according to the digital inductance signal.

[0022] At least one feedback voltage detection circuit is used to receive the analog feedback voltage signal of the power supply device 100 and determine the digital feedback voltage signal of the power supply device 100 based on the analog feedback voltage signal, so as to determine the actual feedback voltage value according to the digital feedback voltage signal.

[0023] At least one output voltage detection circuit is used to receive the analog output voltage signal of the power supply device 100 and determine the digital output voltage signal of the power supply device 100 based on the analog output voltage signal, so as to determine the actual output voltage value according to the digital output voltage signal.

[0024] At least one output current detection circuit is used to receive the analog output current signal of the power supply device 100 and determine the digital output current signal of the power supply device 100 based on the analog output current signal, so as to determine the actual overcurrent protection value according to the digital output current signal.

[0025] As one possible implementation, the power system in this application embodiment may include, but is not limited to, a power supply device 100, a data acquisition circuit 200, and a detection device 300. The power supply device 100 is used to supply power to the target, and the data acquisition circuit 200 is used to acquire the actual output inductance value, actual feedback voltage value, actual output voltage value, and actual overcurrent protection value of the corresponding power supply device 100.

[0031] For example, in combination Figure 2 As shown, the power supply system proposed in this application embodiment may include, but is not limited to: a POL power supply, an inductor detection circuit, a feedback voltage detection circuit, an output voltage detection circuit, an output current detection circuit, a DSP (Digital Signal Processor) control system, and a BMC (Baseboard Management Controller) control module, with each module directly connected via electrical signals.

[0032] The POL power supply receives the P5V_EN signal (the enable signal for the P5V load point power supply) from the DSP control system and controls whether the POL power supply operates based on the high or low level of the P5V_EN signal. The POL power supply transmits the P5V_PG (5V power supply detection signal) detection signal to the DSP control system so that it can monitor the status of the P5V_PG detection signal. When the DSP control system outputs P5V_EN=1, the POL power supply starts to work, outputs the P5V voltage, and P5V_PG goes high.

[0033] Furthermore, in this embodiment, the POL power supply transmits the analog inductor signals P5V_L_DP and P5V_L_DN to the inductor detection circuit via L31; transmits the analog feedback voltage signals P5V_FB_DP and P5V_FB_DN to the feedback voltage detection circuit via R33 and R34; transmits the analog output voltage signals P5V_MONITOR_DP and P5V_MONITOR_DN to the output voltage detection circuit via R35 and R36; and detects the load current via R37 to obtain the analog output current signals Iout_P5V_DP and Iout_P5V_DN, which are then transmitted to the output current detection circuit.

[0034] The inductance detection circuit receives the analog inductance signals P5V_L_DP and P5V_L_DN from the POL power supply, converts them into digital inductance signals, and transmits the digital inductance signals to the DSP control system via I2C (Inter-Integrated Circuit) communication.

[0035] The feedback voltage detection circuit receives the analog feedback voltage signals P5V_FB_DP and P5V_FB_DN from the POL power supply, converts them into digital feedback voltage signals, and transmits the digital feedback voltage signals to the DSP control system via I2C communication.

[0036] The output voltage detection circuit receives the analog output voltage signals P5V_MONITOR_DP and P5V_MONITOR_DN from the POL power supply, converts them into digital output voltage signals, and transmits the digital output voltage signals to the DSP control system via I2C communication.

[0037] The output current detection circuit receives the analog output current signals Iout_P5V_DP and Iout_P5V_DN from the POL power supply, converts them into digital output current signals, and transmits the digital output current signals to the DSP control system via I2C communication.

[0038] This application embodiment converts the analog signal acquired by the acquisition circuit 200 into data, avoiding the quantization error introduced by direct digital signal sampling, improving signal accuracy and anti-interference capability, adapting to different range and accuracy requirements, and enhancing environmental adaptability and diagnostic capability.

[0039] The detection unit 300 is used to identify the power status of the power supply device 100 based on at least one operating parameter of the power supply device 100; detect whether the power supply device 100 meets preset abnormal conditions based on the power status, and collect the target output inductance value, target feedback voltage value, target output voltage value and target overcurrent protection value of the power supply device 100; when the power supply device 100 is detected to meet the preset abnormal conditions, calculate the first difference between the actual output inductance value and the target output inductance value, the second difference between the actual feedback voltage value and the target feedback voltage value, the third difference between the actual output voltage value and the target output voltage value and the fourth difference between the actual overcurrent protection value and the target overcurrent protection value, and identify the actual abnormal result of the power supply device 100 based on the first difference, the second difference, the third difference and the fourth difference.

[0040] It is understood that, in the embodiments of this application, the operating parameters may include, but are not limited to, electrical parameters, time parameters, status signals, and environmental parameters. Among them, electrical parameters may include, but are not limited to, output voltage, output current, power factor, efficiency, ripple voltage, harmonic distortion, etc., and this application does not impose specific limitations; time parameters may include, but are not limited to, cumulative operating time, load change response time, fault duration, etc., and this application does not impose specific limitations; environmental parameters may include, but are not limited to, ambient humidity, temperature, air pressure, dustproof and waterproof rating, etc., and this application does not impose specific limitations; status signals may include, but are not limited to, indicator light signals, alarm signals, vibration / noise abnormality signals, etc., and this application does not impose specific limitations.

[0041] In some embodiments, this application can detect whether the power supply device 100 meets certain abnormal conditions by power status detection, and use the acquisition circuit 200 to acquire the target output inductance value, target feedback voltage value, target output voltage value, and target overcurrent protection value of the power supply device 100. The certain abnormal conditions can be set by those skilled in the art according to actual conditions, and this application does not impose specific limitations.

[0042] It should be noted that, in the embodiments of this application, the target output inductance value can be understood as the inductance value expected to be achieved by the inductance detection circuit in the acquisition circuit 200; the target feedback voltage value can be understood as the voltage value expected to be achieved by the feedback voltage detection circuit in the acquisition circuit 200; the target output voltage value can be understood as the voltage value expected to be achieved by the output voltage detection circuit in the acquisition circuit 200; and the target overcurrent protection value can be understood as the current value expected to be achieved by the output current detection circuit in the acquisition circuit 200. This application does not impose any specific limitations.

[0043] Furthermore, in this embodiment of the application, when the power supply device 100 is detected to meet certain abnormal conditions, the first difference between the actual output inductance value and the target output inductance value, the second difference between the actual feedback voltage value and the target feedback voltage value, the third difference between the actual output voltage value and the target output voltage value, and the fourth difference between the actual overcurrent protection value and the target overcurrent protection value are calculated, and then the actual abnormal result of the power supply device 100 is identified based on the first difference, the second difference, the third difference, and the fourth difference.

[0044] For example, embodiments of this application can be combined with Figure 2 As shown, the DSP control system receives digital inductance signals from the inductor detection circuit via I2C communication, digital feedback voltage signals from the feedback voltage detection circuit via I2C communication, digital output voltage signals from the output voltage detection circuit via I2C communication, and digital output current signals from the output current detection circuit via I2C communication. Through a series of complex algorithms, it identifies the power supply status of the power supply device 100 and sequentially determines any abnormal results of the power supply device 100, such as... Figure 3 As shown, the following are, in order: inductor malfunction; loop malfunction; output current reaching the OCP set value; FB malfunction of the POL power chip; POL power chip malfunction, etc. This application does not impose specific limitations.

[0045] Furthermore, in the embodiments of this application, when a fault occurs, the DSP control system can be controlled to output P5V_EN=0, shutting down the POL power supply. Simultaneously, fault information such as inductor abnormality, loop abnormality, output current reaching the OCP set value, POL power chip FB abnormality, and POL power chip malfunction is transmitted to the BMC control module via I2C communication so that it can inform the user and alert them to the system fault status.

[0046] When the BMC control module receives a fault signal from the DSP control system, it promptly informs the user to replace the corresponding board and records fault information such as inductor abnormality, loop abnormality, output current reaching the OCP set value, POL power chip FB abnormality, and POL power chip abnormality in the log, thus alerting the user to the system fault status.

[0047] It should be noted that the DSP control system in this embodiment monitors and acquires the actual output inductance value, actual feedback voltage value, actual output voltage value, and actual overcurrent protection value of the power supply device 100 in real time. Then, it stores the actual output voltage P5V of the P5V power supply, the reference voltage of the POL power chip feedback point (i.e., the actual feedback voltage value) P5V_FB, the output filter inductance value (i.e., the actual output inductance value) L, and the OCP protection value (i.e., the actual overcurrent protection value) Iocp_P5V in the register. In addition, the DSP control system can also store the first target output voltage value P5V_RMS_set, the fourth target output voltage value (i.e., the target output voltage ripple value P5V_RIPPLE_set), the target feedback voltage value P5V_FB_ref, the target output inductance value L_set, and the target overcurrent protection value Iocp_P5V_set in the register.

[0048] Optionally, in one embodiment of this application, the detection element 300 includes: a first calculation unit, configured to calculate a first target output voltage value, a second target output voltage value, and a third target output voltage value of the power supply device 100 based on a target output voltage value, and to calculate a fourth target output voltage value between the second target output voltage value and the third target output voltage value based on the second target output voltage value and the third target output voltage value; a second calculation unit, configured to calculate a first actual output voltage value, a second actual output voltage value, and a third actual output voltage value of the power supply device 100 based on an actual output voltage value, and to calculate a fourth actual output voltage value between the second actual output voltage value and the third actual output voltage value based on the second actual output voltage value and the third actual output voltage value; a third calculation unit, configured to calculate a first output voltage difference between the first target output voltage value and the first actual output voltage value, and to calculate a second output voltage difference between the fourth target output voltage value and the fourth actual output voltage value; and a generation unit, configured to obtain a third difference based on the first output voltage difference and the second output voltage difference.

[0049] In some embodiments, the first calculation unit in this application embodiment can calculate the first target output voltage value, the second target output voltage value, and the third target output voltage value of the power supply device 100 based on the target output voltage value, and calculate the fourth target output voltage value between the second target output voltage value and the third target output voltage value based on the second target output voltage value and the third target output voltage value.

[0050] For example, in the embodiments of this application, the effective value of the output voltage of P5V electrical P5V_RMS_set (i.e., the first target output voltage value), the second target output voltage value and the third target output voltage value can be determined by the first calculation unit, and then the ripple P5V_RIPPLE_set (i.e., the fourth target output voltage value) can be calculated by the second target output voltage value and the third target output voltage value.

[0051] In some embodiments, the second calculation unit in this application embodiment can calculate the first actual output voltage value, the second actual output voltage value, and the third actual output voltage value of the power supply device 100 based on the actual output voltage value, and then calculate the fourth actual output voltage value between the second actual output voltage value and the third actual output voltage value.

[0052] For example, in the DSP control system of this application embodiment, the number of times the P5V output voltage is sampled within the switching cycle T1 is N1, respectively. ,in, For the first The instantaneous voltage value of the next sample. For the first The instantaneous voltage value of the next sample. For the first The instantaneous voltage value of the sampled voltage is used to calculate the effective value of the output voltage of P5V (i.e., the first actual output voltage value), the maximum output voltage value (i.e., the second actual output voltage value), and the minimum output voltage value (i.e., the third actual output voltage value). The operating frequency of the DSP control system can be 1000MHz; this application does not impose specific limitations.

[0053] The formula for calculating the first actual output voltage value can be, but is not limited to, the following: , The formula for calculating the second actual output voltage value can be, but is not limited to, the following: , The third actual output voltage value can be, but is not limited to: , Furthermore, in embodiments of this application, a fourth actual output voltage value, i.e., the output voltage ripple value, can be calculated based on the second and third actual output voltage values. The calculation formula may be, but is not limited to, the following: , in, This indicates the second actual output voltage value. This represents the third actual output voltage value.

[0054] Furthermore, in this embodiment of the application, the third calculation unit can calculate the first output voltage difference between the first target output voltage value and the first actual output voltage value, and the second output voltage difference between the fourth target output voltage value and the fourth actual output voltage value, and then use the generation unit to obtain the third difference.

[0055] In this embodiment, the first and second calculation units calculate multi-level target values, actual values, specific target differences, and specific actual differences based on target values ​​and actual values, respectively. Then, the third calculation unit calculates the corresponding level differences and synthesizes them to obtain the third difference. Voltage-related data is obtained from different dimensions, achieving comprehensive coverage of multi-level calculations. This enables accurate location of the root cause of anomalies, enhances the reliability of anomaly detection, facilitates fault classification and handling, and adapts to complex and ever-changing power supply environments.

[0056] Optionally, in one embodiment of this application, the detection element 300 includes: a judgment unit, used to judge whether a third difference meets a preset difference condition; a first identification unit, used to identify an actual abnormal result based on the first difference when the third difference meets the preset difference condition; and a second identification unit, used to identify an actual abnormality based on the second difference and the fourth difference when the third difference does not meet the preset difference condition.

[0057] It can be understood that a certain difference condition can be that P5V_RMS is within the range of P5V_RMS_set±10%, and P5V_RIPPLE is not within the range of P5V_RIPPLE_set±10%. The specific settings can be made by those skilled in the art according to the actual situation, and this application does not impose specific restrictions.

[0058] In some embodiments, the present application can determine whether the third difference meets certain difference conditions, and if it does, identify the actual abnormal result based on the first difference; and if it does not meet the conditions, identify the actual abnormal result based on the second difference and the fourth difference.

[0059] For example, embodiments of this application can determine whether P5V_RMS is within the range of P5V_RMS_set±10% and whether P5V_RIPPLE is not within the range of P5V_RIPPLE_set±10%. When P5V_RMS is within the range of P5V_RMS_set±10% and P5V_RIPPLE is not within the range of P5V_RIPPLE_set±10%, the third difference is determined to meet a certain difference condition, and the actual abnormal result is identified based on the first difference. When P5V_RMS is not within the range of P5V_RMS_set±10% or P5V_RIPPLE is within the range of P5V_RIPPLE_set±10%, the third difference is determined not to meet a certain difference condition, and the actual abnormality is identified based on the second and fourth differences.

[0060] In this embodiment, the judgment unit can determine whether the third difference meets a certain difference condition, and the first and second recognition units can determine whether the actual abnormal result is obtained based on the first difference or based on the second and fourth differences. This conditional triggering mechanism reduces the false judgment rate, avoids over-diagnosis, focuses on key faults, improves diagnostic accuracy, suppresses transient interference, and enhances robustness.

[0061] Optionally, in one embodiment of this application, the first identification unit includes: a first judgment subunit, used to determine whether the first difference is less than a preset inductance threshold; a first determination subunit, used to determine that the actual abnormal result is a power chip loop abnormality of the power supply device 100 when the first difference is less than the preset inductance threshold; and a second determination subunit, used to determine that the actual abnormal result is an inductance abnormality of the power supply device 100 when the first difference is greater than or equal to the preset inductance threshold.

[0062] In some embodiments, this application can determine whether the first difference is less than a certain inductance threshold when the third difference meets a certain difference condition. If the difference is less than the certain inductance threshold, the actual abnormal result is determined to be a power chip loop abnormality of the power supply device 100; and if the difference is greater than or equal to the certain inductance threshold, the actual abnormal result is determined to be an inductance abnormality of the power supply device 100. The certain inductance threshold can be set by those skilled in the art according to actual conditions, and this application does not impose specific limitations.

[0063] For example, in this embodiment of the application, when P5V_RMS is within the range of P5V_RMS_set±10% and P5V_RIPPLE is not within the range of P5V_RIPPLE_set±10%, it can determine whether the inductance value L is within the range of L_set±20%. If the inductance value L is within the range of L_set±20%, it determines that the actual abnormal result is a loop abnormality of the POL power chip, outputs P5V_EN=0, shuts down the POL power supply, and transmits the fault information to the BMC control module. If the inductance value L is not within the range of L_set±20%, it determines that the actual abnormal result is an inductor abnormality, outputs P5V_EN=0, shuts down the POL power supply, and transmits the fault information to the BMC control module.

[0064] The embodiments of this application can use a first judgment subunit to determine whether the first difference is less than a certain inductance threshold, and use a first determination subunit to determine that the actual abnormal result is a power chip loop abnormality of the power supply device 100, and use a second determination subunit to determine that the actual abnormal result is an inductance abnormality of the power supply device 100. By using the difference between inductance characteristics and loop response, a binary fault isolation mechanism is constructed, which significantly improves the accuracy, efficiency and maintainability of power supply fault diagnosis.

[0065] Optionally, in one embodiment of this application, the second identification unit includes: a second judgment subunit, configured to determine whether a fourth difference is greater than or equal to a preset current threshold; a third determination subunit, configured to determine that the actual abnormal result is that the output current of the power supply device 100 reaches the target value when the fourth difference is greater than or equal to the preset current threshold; a third judgment subunit, configured to determine whether a second difference is less than or equal to a preset voltage threshold when the fourth difference is less than the preset current threshold; a fourth determination subunit, configured to determine that the actual abnormal result is that the power supply chip of the power supply device 100 is abnormal when the second difference is less than or equal to the preset voltage threshold; and a fifth determination subunit, configured to determine that the actual abnormal result is that the voltage of the power supply device 100 is abnormal when the second difference is greater than the preset voltage threshold.

[0066] In some embodiments, if the third difference does not meet a certain difference condition, this application can determine whether the fourth difference is greater than or equal to a certain current threshold. If it is greater than or equal to, the actual abnormal result is determined to be that the output current of the power supply device 100 has reached the target value. Otherwise, it can determine whether the second difference is less than or equal to a certain voltage threshold. If it is less than or equal to, the actual abnormal result is determined to be that the power supply chip of the power supply device 100 is abnormal. Otherwise, the actual abnormal result is determined to be that the voltage of the power supply device 100 is abnormal. The certain current threshold and the certain voltage threshold can be set by those skilled in the art according to actual conditions, and this application does not impose specific limitations.

[0067] For example, in this embodiment of the application, when P5V_RMS is not within the range of P5V_RMS_set ± 10%, or P5V_RIPPLE is within the range of P5V_RIPPLE_set ± 10%, the output current Iout_P5V is used to determine whether the output voltage is abnormal due to OCP triggered by the output current. When Iout_P5V ≥ 1.05 * Iocp_P5V_set, the P5V output current reaches the OCP set value, P5V_EN = 0 is output, the POL power supply is turned off, and the fault information is transmitted to the BMC control module; when Iout_P5V < 1.05 * Iocp_P5V_set, the output current reaches the OCP set value, P5V_EN = 0 is output, the POL power supply is turned off, and the fault information is transmitted to the BMC control module; when Iout_P5V < 1.05 * Iocp_P5V_set, the output current reaches the OCP set value, the output current reaches the OCP set value, P5V_EN = 0 is output, the POL power supply is turned off, and the fault information is transmitted to the BMC control module. When 5V_set is applied, it checks whether P5V_FB is within the range of P5V_FB_ref±5%. If P5V_FB is not within the range of P5V_FB_ref±5%, the actual abnormal result is determined to be an abnormal chip FB voltage, and P5V_EN=0 is output, the POL power supply is turned off, and the fault information is transmitted to the BMC control module. If P5V_FB is within the range of P5V_FB_ref±5%, the actual abnormal result is determined to be an abnormal POL power chip, and P5V_HDD_EN (the enable signal of the electronic fuse of P5V_HDD)=0 is output, the POL power supply is turned off, and the fault information is transmitted to the BMC control module.

[0068] This application embodiment can use a second judgment subunit to determine whether the fourth difference is greater than or equal to a certain current threshold, and use a third determination subunit to determine that the actual abnormal result is that the output current of the power supply device 100 has reached the target value. Alternatively, the third judgment subunit can determine whether the second difference is less than or equal to a certain voltage threshold, and use a fourth determination subunit to determine that the actual abnormal result is that the power chip of the power supply device 100 is abnormal. The fifth determination subunit can determine that the actual abnormal result is that the voltage of the power supply device 100 is abnormal. By adopting a current-priority hierarchical judgment strategy, it first confirms whether the protection is triggered due to output current overload, and then investigates voltage-related faults. This avoids the complexity of simultaneous analysis of multiple parameters, reduces misjudgments, improves diagnostic efficiency, and has clear logic. It balances response speed and diagnostic comprehensiveness, and can maximize the protection of equipment safety. It is especially suitable for power supply monitoring scenarios with high real-time requirements.

[0069] Optionally, in one embodiment of this application, it further includes: a first identification module, configured to identify repairable and unrepairable anomalies in the actual abnormal results after identifying the actual abnormal results of the power supply device 100; a first generation module, configured to generate a repairable instruction for the power supply device 100 based on the repairable anomaly, and repair the power supply device 100 according to the repairable instruction; and a second generation module, configured to determine the anomaly level of the power supply device 100 based on the unrepairable anomaly, and generate an alarm indication for the power supply device 100 according to the anomaly level.

[0070] It is understood that, in the embodiments of this application, repairable anomalies can be understood as faults that can be recovered through parameter adjustment, component replacement, or software configuration, while unrepairable anomalies can be understood as faults where the core hardware of the power supply device 100 is damaged or requires complete replacement. Specific settings can be made by those skilled in the art according to actual circumstances, and this application does not impose specific limitations. Generally speaking, in the embodiments of this application, inductor anomalies, power chip loop anomalies, and voltage anomalies of the power supply device 100 can be identified as repairable anomalies; power chip anomalies and output current reaching a target value of the power supply device 100 can be identified as unrepairable anomalies, and this application does not impose specific limitations.

[0071] In some embodiments, the actual abnormal results of the power supply device 100 can be divided into repairable abnormalities and unrepairable abnormalities. The specific settings can be made by those skilled in the art according to the actual situation, and this application does not impose any specific limitations.

[0072] Furthermore, in this embodiment of the application, for repairable anomalies, a repairable instruction for the power supply device 100 can be generated, and then the power supply device 100 that has malfunctioned can be repaired according to the repairable instruction.

[0073] For example, in the case where the actual abnormal result is an inductor malfunction in the power supply device 100, the repairable instruction can be determined to be replacing the inductor component or adjusting circuit parameters, etc., and this application does not impose specific limitations; in the case where the actual abnormal result is a power chip loop malfunction in the power supply device 100, the repairable instruction can be determined to be recalibrating the loop parameters or replacing the sampling resistor or optocoupler, etc., and this application does not impose specific limitations; in the case where the actual abnormal result is a voltage malfunction in the power supply device 100, the repairable instruction can be determined to be checking the pin circuit connection or replacing the voltage divider resistor, etc., and this application does not impose specific limitations. Furthermore, in this embodiment of the application, for unrepairable anomalies, the anomaly level of the power supply device 100 can be determined, and an alarm indication for the power supply device 100 can be generated.

[0074] For example, in the embodiment of this application, when the actual abnormal result is that the power chip of the power supply device 100 is abnormal, the abnormality level can be determined to be "serious" and an alarm indication combining red light flashing and buzzer alarm can be given; when the actual abnormal result is that the output current of the power supply device 100 reaches the target value, the abnormality level can be determined to be "serious" and red light flashing can be given. The specific settings can be made by those skilled in the art according to the actual situation, and this application does not impose specific limitations.

[0075] This application embodiment can use a first identification module to classify actual abnormal results into repairable abnormalities and unrepairable abnormalities. Then, for repairable abnormalities, a first generation module generates a repairable instruction for the power supply device 100 and repairs the power supply device 100 according to the repairable instruction. For unrepairable abnormalities, a second generation module determines the abnormality level of the power supply device 100 and generates a corresponding alarm indication. Through differentiated processing, faults can be accurately located, repair time can be shortened, repairable and unrepairable abnormalities can be distinguished, dynamic resource allocation can be achieved, maintenance costs can be optimized, abnormality levels can be quantified, risk classification and control can be achieved, system security can be improved, and the adaptability to scenarios can be more diversified.

[0076] Optionally, in one embodiment of this application, it further includes: an acquisition module, used to acquire historical abnormal results of the target power device before generating a repairable instruction for the power device 100; a second identification module, used to identify historical repairable abnormalities in the historical abnormal results; and a third generation module, used to construct a fault repair database and / or a fault repair model based on the historical repairable abnormalities and the historical repairable instructions corresponding to the historical repairable abnormalities, so as to generate repairable instructions using the fault repair database and / or the fault repair model.

[0077] It is understood that the embodiments of this application generate corresponding repairable instructions by constructing a fault repair database or a fault repair model.

[0078] The fault repair model can be, but is not limited to, a rule-based expert system model, a machine learning-based classification model (such as decision trees, neural networks, etc., which are not specifically limited in this application), and a physical model-based simulation model, or a combination of multiple models. The specific configuration can be determined by those skilled in the art based on actual conditions, and this application does not impose specific limitations. Specifically, the model can be as follows: First, the identified historical repairable anomalies are input into each model. The rule-based expert system model quickly determines repair methods for some common faults based on the target rule base. For example, if the anomaly is caused by simple parameter fluctuations, the rule base will clearly indicate the instruction to adjust the parameters. The machine learning-based classification model learns from a large number of historical repairable anomalies and corresponding historical repairable instructions to more accurately classify the anomalies and predict possible repairable instructions. The physical model-based simulation model simulates the operating state of the power supply device 100 under different repairable instructions to verify the feasibility of the repairable instructions. Finally, the output results of the three models are combined to generate the optimal repairable instruction, such as "replace the sampling resistor, change the specifications, and adjust the resistance R2 on the circuit board to 2 ohms," which is not specifically limited in this application.

[0079] In addition, the repair process of the power supply device 100 can also be regarded as a reinforcement learning problem in the embodiments of this application. By defining the state space as various operating parameters and historical abnormal results of the power supply device 100, the action space as various possible historical repairable instructions, and the reward function set according to the performance of the repaired device and the repair cost, a corresponding fault repair model can be constructed.

[0080] In addition, this application embodiment can also use augmented reality technology to overlay the historical abnormal results, historical repairable abnormalities and historical repairable instructions of the power supply device 100 in real time in the field of vision of the technician, thereby constructing a corresponding three-dimensional structural model to help the technician complete the repair work more accurately and efficiently.

[0081] As one possible approach, embodiments of this application can obtain historical anomaly results of the target power supply device, identify the corresponding historical repairable anomalies and historical repairable instructions, thereby constructing a fault repair model and generating repairable instructions.

[0082] In some embodiments, this application can construct a fault repair database by obtaining historical anomaly results of the target power device and identifying the corresponding historical repairable anomalies and historical repairable instructions, thereby generating repairable instructions.

[0083] This application embodiment acquires historical anomaly results of the target power supply device through an acquisition module and identifies historical repairable anomalies based on a first identification module. Then, a third generation module constructs a fault repair database or fault repair model, and generates repairable instructions for the power supply device 100 based on this database or model. This fully leverages the value of historical data, avoiding data idleness and waste. It achieves data accumulation and knowledge retention, providing solid support for subsequent equipment maintenance and repair work. By constructing the database or model, when equipment anomalies occur, repair instructions can be quickly generated, shortening repair time, improving equipment repair efficiency, reducing manual intervention, and avoiding repair delays caused by insufficient human experience or negligence. This gives the system a certain degree of autonomous analysis and decision-making capability.

[0084] Optionally, in one embodiment of this application, it further includes: a judgment module, used to determine whether the actual state of the acquisition circuit 200 is in normal working condition before acquiring the actual output inductance value, actual feedback voltage value, actual output voltage value and actual overcurrent protection value of the power supply device 100; a first acquisition module, used to prohibit the acquisition of the actual output inductance value, actual feedback voltage value, actual output voltage value and actual overcurrent protection value when the actual state is not in normal working condition; and a second acquisition module, used to allow the acquisition of the actual output inductance value, actual feedback voltage value, actual output voltage value and actual overcurrent protection value when the actual state is in normal working condition.

[0085] It is understood that the judgment module in this application embodiment can determine whether the actual state of the acquisition circuit 200 is a normal working state, and when the actual state is not a normal working state, the first acquisition module prohibits the acquisition of the actual output inductance value, the actual feedback voltage value, the actual output voltage value and the actual overcurrent protection value; when the actual state is a normal working state, the second acquisition module allows the acquisition of the actual output inductance value, the actual feedback voltage value, the actual output voltage value and the actual overcurrent protection value.

[0086] For example, the normal standard for the output voltage in this application embodiment can be that it is stable within ±2% of the nominal value (e.g., 5V ± 0.1V); the normal standard for the output current can be that it does not exceed 110% of the rated current, and the long-term operating current is ≤80% of the rated value; the normal standard for the power factor is ≥0.8 (ideal value 1); the normal standard for ripple and noise is that the peak-to-peak value of the ripple voltage is ≤50mV (DC power supply), and the harmonic distortion of the AC power supply is ≤5%, etc. This application does not impose specific limitations.

[0087] Furthermore, the embodiments of this application can determine that the actual state of the acquisition circuit 200 is not in normal working condition when the output voltage fluctuation exceeds ±5% or continuously deviates from the nominal value; when the output current continuously exceeds the limit or suddenly drops to 0; when the power factor is <0.7; and when the ripple exceeds the standard or the noise spectrum shows abnormal peaks. This can accurately identify the working state of the acquisition circuit 200 and ensure the reliability of data acquisition.

[0088] In this embodiment, before acquiring the actual output inductance value, actual feedback voltage value, actual output voltage value, and actual overcurrent protection value of the power supply device 100 using the acquisition circuit 200, it can first determine whether the actual state of the acquisition circuit 200 is in normal working condition. If it is not in normal working condition, acquisition is prohibited; otherwise, acquisition is performed normally. When the acquisition circuit 200 is abnormal, data acquisition is directly prohibited to avoid inputting erroneous data into the control algorithm, thereby blocking erroneous data from the source, improving the accuracy of system decision-making, refining fault location, shortening maintenance time, reducing operation and maintenance costs, and optimizing resource allocation.

[0108] Through the above description of the embodiments, those skilled in the art can clearly understand that the methods according to the above embodiments can be implemented by means of software plus necessary general-purpose hardware platforms. Of course, they can also be implemented by hardware, but in many cases the former is a better implementation method.

[0109] According to the power supply system proposed in the embodiments of this application, the actual output inductance value, actual feedback voltage value, actual output voltage value, and actual overcurrent protection value of the power supply device can be collected by the acquisition circuit. The power supply status of the power supply device can be identified based on operating parameters by the detection device, and it can be detected whether the power supply device meets certain abnormal conditions. The target output inductance value, target feedback voltage value, target output voltage value, and target overcurrent protection value are also collected. Furthermore, when certain abnormal conditions are detected, the system calculates the first difference between the actual output inductance value and the target output inductance value, the second difference between the actual feedback voltage value and the target feedback voltage value, the third difference between the actual output voltage value and the target output voltage value, and the fourth difference between the actual overcurrent protection value and the target overcurrent protection value. The difference is used to identify the actual abnormal results of the power supply equipment based on the first, second, third, and fourth differences. Therefore, it can solve the problem in related technologies where it is difficult to accurately locate the specific root cause of abnormal trigger voltage in the power supply system, and it is impossible to provide effective board repair guidance for maintenance personnel. At the same time, in-depth analysis of the actual abnormal results not only consumes a lot of manpower, but also easily causes serious consequences such as interruption of operation of downstream equipment, system power failure, and even damage to downstream equipment during the process of troubleshooting abnormalities. The technical effect of accurately analyzing the cause of abnormal trigger voltage in the power supply system is to reduce the cost of manpower analysis, guide maintenance personnel to repair faulty boards, and shut down the power supply system in a timely manner to avoid the impact of abnormal output voltage on downstream equipment and improve loop stability.
