Description

Technical Field

[0001] The present invention relates to the field of power supply control, and more particularly to a compatibility method, system and medium for a multi-voltage adapter based on Feiteng D3000. Background Art

[0002] As a key hardware platform for domestically produced CPUs, the Feiteng (FT) D3000 platform's power management architecture directly impacts system stability and compatibility. Existing technology uses a fixed voltage adaptation mode for the FT D3000 motherboard's power input. This means that after the adapter is directly connected to the motherboard via a power socket, the internal power conversion module (such as a DC-DC step-down circuit) generates the 3.3V, 5V, and 1.2V voltages required by the chips. In practice, the input voltage is typically 12V, 19V, or 24V, but the motherboard only supports a single voltage input. For example, if the motherboard is designed for 12V input, it will not be compatible with a 19V or 24V adapter, and vice versa. The core issue with this architecture is the lack of a multi-voltage adaptive mechanism, which can lead to damage to the power module or motherboard due to the mis-insertion of adapters with different voltages.

[0003] Furthermore, existing technologies lack adaptability to complex operating conditions. For example, after long-term use, the output voltage of an adapter may drift due to component aging. However, traditional solutions cannot dynamically adjust the voltage threshold, further exacerbating compatibility issues. Therefore, power supply architectures based on the FT D3000 platform have significant deficiencies in compatibility, safety, and energy efficiency. A solution that supports multi-voltage adaptive input, integrated intelligent protection, and dynamic optimization is urgently needed. Summary of the Invention

DETAILED DESCRIPTION

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

On the contrary, the various steps may be processed in reverse order or simultaneously. At the same time, other operations may be added to these processes, or one or more steps may be removed from these processes.

[0021] In addition, the functional modules in the various embodiments of the present invention may be integrated together to form an independent part, or each module may exist independently, or two or more modules may be integrated to form an independent part.

[0022] Figure 1 The figure shows a topological connection diagram of a compatible circuit of a multi-voltage adapter based on Feiteng D3000.

[0023] like Figure 1 As shown, a compatible circuit 10 of a multi-voltage adapter based on Feiteng D3000 includes: The CPLD module 101 is used to isolate and output a logic switch control signal based on a judgment logic signal of an input voltage; A first power switch module 102, configured to switch on or off a first power source according to the switch control signal; A second power switch module 103, configured to switch on or off a second power source according to the switch control signal; The voltage regulating module 104 is configured to adjust the second power supply to a specified voltage range according to the voltage regulating parameters; The voltage measurement module 105 is configured to measure the voltage value of the first power supply or the adjusted voltage value of the second power supply.

[0024] It should be noted that the CPLD module receives input voltage from the adapter and generates a logic switch control signal based on the input voltage to control the first and second power switch modules. The logic switch control signal is an isolated signal. The first power switch module controls the on / off state of the first power supply. In practical applications, the first power supply is a 12V power supply. The second power switch module controls the on / off state of the second power supply. In practical applications, the second power supply is a 19V or 24V power supply. The voltage regulation module steps down the second power supply to provide output power. The voltage measurement module measures the output voltage.

[0025] Figure 2 The flowchart of the compatibility method of the multi-voltage adapter based on Feiteng D3000 of the present invention is shown.

[0026] like Figure 2 As shown, the first aspect of the present invention discloses a compatibility method for a multi-voltage adapter based on Feiteng D3000, the method comprising: S202, detecting a DC voltage input by the adapter to obtain first voltage information; S204, generating a first switch control signal according to the first voltage information based on a preset voltage threshold comparison logic; S206, determining whether the first switch control signal is a first power-on signal; S208, if yes, turning on the first power supply and obtaining second voltage information according to the first voltage information; If not, then turn on the second power supply, configure the first voltage regulation parameter of the voltage regulation module based on a preset voltage regulation logic, and obtain second voltage information according to the first voltage information. S212, obtaining first confidence information according to the second voltage information based on a preset confidence setting logic; S214, determining whether the first confidence information exceeds a preset first confidence threshold; S216: If yes, adjust the first voltage regulation parameter or trigger a redundant protection mechanism.

[0027] It should be noted that the first voltage information is the input voltage value of the compatible circuit of the multi-voltage adapter, that is, the DC voltage value input by the adapter; the first switch control signal is a logic control signal used to drive the first power switch module and the second power switch module; the second voltage information is the output voltage value of the compatible circuit of the multi-voltage adapter; the first voltage regulation parameter is a control parameter used to adjust the output state of the voltage regulation module; and the first confidence information is used to determine that the output voltage is in an abnormal state.

[0028] In this embodiment, first, by detecting the DC voltage input by the adapter, first voltage information, i.e., the input voltage, is obtained. Then, based on the comparison of the input voltage value with a preset voltage threshold range, a corresponding first switch control signal is generated to drive the corresponding power switch module to select the power path. When the first power source is connected, the output voltage is directly output based on the first power source. When the second power source is connected, the first voltage regulation parameter of the voltage regulation module is configured using a preset voltage regulation logic to obtain the output voltage. This achieves compatibility with multiple voltage adapters. Furthermore, based on a preset confidence setting logic, the voltage curve of the output voltage is analyzed to obtain the probability of being in an abnormal state, i.e., the abnormality confidence level. When the abnormality confidence level exceeds the preset first confidence threshold, it indicates the presence of an abnormality. In this case, the voltage regulation module is adjusted to reduce the output voltage or limit the output current, or a redundant protection mechanism is triggered to form multiple protections, thereby improving the reliability and safety of the product.

[0029] Figure 3 The flowchart of the operation of a voltage threshold comparison logic provided by an embodiment of the present invention is shown.

[0030] According to an embodiment of the present invention, Figure 3 As shown, the preset voltage threshold comparison logic generates a first switch control signal according to the first voltage information, specifically: S302, determining whether the first voltage information is within a preset first voltage threshold range; S304, if yes, generate a first switch control signal according to the first power-on signal; S306, if not, determining whether the first voltage information is within a preset second voltage threshold range; S308, if yes, generating a first switch control signal according to the second power-on signal, and setting the system to enter the first voltage regulation mode; S310: If not, generate a first switch control signal according to the third power-on signal, and set to enter the second voltage regulation mode.

[0031] It should be noted that the first power-on signal is used to drive the first power switch module to turn on the first power supply; the second power-on signal is used to drive the second power switch module to turn on the second power supply and to set the device to enter the first voltage regulation mode; the third power-on signal is used to drive the second power switch module to turn on the second power supply and to set the device to enter the second voltage regulation mode.

[0032] In this embodiment, the operating process of the voltage threshold comparison logic provided is specifically as follows: if the first voltage information is within a preset first voltage threshold range, a first switch control signal is generated according to a first power-on signal; if the first voltage information is within a preset second voltage threshold range, a first switch control signal is generated according to the second power-on signal, and the first voltage regulation mode is set to be entered.

[0033] As an implementation method, for example, in a 12V FT D3000 power supply system, if the input voltage is within the range of [11.5V, 12.5V], it means that a 12V adapter is connected. At this time, the first switch control signal is set to the first power-on signal. If the input voltage is within the range of [18V, 20V] or [22.5V, 25.5V], it means that a 19V or 24V adapter is connected. At this time, the first switch control signal is set to the second power-on signal, and the first voltage regulation mode is entered. If the input voltage is not within the above range, it means that a non-standard voltage adapter is connected. At this time, the first switch control signal is set to the third power-on signal, and the second voltage regulation mode is entered. The above process can achieve the purpose of compatibility with multiple voltage adapters.

[0034] Figure 4 A flowchart of the operation of a voltage regulation logic provided by an embodiment of the present invention is shown.

[0035] According to an embodiment of the present invention, Figure 4 As shown, the first voltage regulation parameter of the voltage regulation module is configured based on the preset voltage regulation logic, and the second voltage information is obtained according to the first voltage information, specifically: S402, determining whether to enter the first voltage regulation mode; S404: If yes, setting the first voltage regulation parameter according to a preset first voltage regulation reference value; S406, if not, query historical voltage regulation parameters and set the first voltage regulation parameters; S408: Configure the voltage regulation module according to the first voltage regulation parameter to obtain second voltage information.

[0036] It should be noted that this embodiment provides a flow chart for operating the voltage regulation logic. Entering the first voltage regulation mode indicates that a standard adapter (19V or 24V) is connected. In this case, the voltage regulation reference values ​​corresponding to the standard adapter are used to set the first voltage regulation parameters. Otherwise, this indicates that a non-standard adapter is connected. In this case, the first voltage regulation parameters are set based on the most recent voltage regulation parameters from the historical voltage regulation parameters. By selecting the first voltage regulation parameters in this manner, the time required to adjust the input voltage to the target voltage is minimized, thereby improving voltage regulation speed.

[0037] According to an embodiment of the present invention, the further embodiment includes: Calculating a difference between the second voltage information and preset target voltage information to obtain first deviation information; Based on a preset feedback adjustment algorithm, the first voltage adjustment parameter is updated according to the first deviation information; configuring the voltage regulation module according to the first voltage regulation parameter and updating the second voltage information; The first voltage information and the first voltage regulation parameter are recorded and stored.

[0038] It should be noted that the target voltage information is the target value of the output voltage after voltage regulation. In this embodiment, a feedback regulation algorithm is used to control the voltage regulation module to output the target voltage value. As an implementation method, the feedback regulation operation is implemented using a PID algorithm. First, the deviation between the current output voltage and the target output voltage is calculated; then, the deviation value is passed to the PID algorithm to obtain a regulation variable, which is used to update the first voltage regulation parameter; finally, the updated regulation variable is configured in the voltage regulation module to achieve the purpose of adjusting the output voltage. In addition, the input voltage and the first voltage regulation parameter of the voltage regulation module are recorded and stored as historical voltage regulation parameters.

[0039] According to an embodiment of the present invention, the first confidence information is obtained according to the second voltage information based on the preset confidence setting logic, specifically: obtaining a voltage curve according to the second voltage information; According to the voltage curve, obtaining a fluctuation amplitude of the second voltage information when the second voltage information is in a steady state stage; Based on a preset fluctuation range, the first confidence information is updated according to the fluctuation amplitude.

[0040] It should be noted that in this embodiment, an operational process for the confidence setting logic is provided. When the output voltage is in a steady-state phase, the output voltage fluctuation amplitude is collected; wherein, the steady-state phase is the period within a preset time window in which the average value of the output voltage is within the target voltage range. Then, based on the relationship between the fluctuation amplitude and the fluctuation range, the first confidence information is updated. As an embodiment, when the fluctuation amplitude exceeds the preset fluctuation range, the first confidence information is adjusted upward; when several consecutive obtained fluctuation amplitudes are within the preset fluctuation range, the first confidence information is adjusted downward.

[0041] According to an embodiment of the present invention, the further embodiment includes: When determining that the redundant protection mechanism is triggered; An abnormality log is generated and stored according to the voltage curve, the fluctuation amplitude and the first voltage regulation parameter.

[0042] It should be noted that when the redundant protection mechanism is triggered, an audio / visual prompt will be generated. As an implementation, in systems with a backup power supply, the input power source will be switched to the backup power source. In addition, an abnormality log will be generated based on the output voltage curve, voltage fluctuation amplitude, and the first voltage regulation parameters for subsequent query and analysis.

[0043] It is worth mentioning that it also includes: When the first power supply or the second power supply is turned on, obtaining first current information; Obtaining a current change rate according to the first current information; If the current change rate exceeds a preset change rate threshold, the first power switch module or the second switch module is driven to enter a slow shutdown mode.

[0044] It should be noted that the first current information is the real-time current value when the first power switch module or the second switch module performs a switching action. In this embodiment, a slow shutdown operation process is provided. During the power switching operation, if the rate of change of the switching current exceeds a preset rate of change threshold, it indicates that there is a sudden change in the current and there is an abnormal risk. At this time, the CPLD module drives the first power switch module or the second switch module to enter the slow shutdown mode, and by adjusting the delay time of the delay circuit, it plays a role in protecting the device.

[0045] It is worth mentioning that it also includes: When it is determined that the second power supply is turned on; Acquiring temperature information of the voltage regulation module; Determining whether the temperature information exceeds a preset temperature threshold; If so, the voltage regulation module is configured to enter the current limiting mode.

[0046] It should be noted that this embodiment provides an over-temperature protection process. When the temperature of the voltage regulator module exceeds a preset temperature threshold, to ensure the operational reliability of the voltage regulator module and the entire circuit system, it will enter current limiting mode, reducing the current output to achieve the purpose of cooling.

[0047] It is worth mentioning that it also includes: Sending the exception log to a preset exception processing neural network model to obtain feedback adjustment weights; The operation weight of the feedback adjustment algorithm is updated according to the feedback adjustment weight.

[0048] It should be noted that in this embodiment, the exception processing neural network model also analyzes the exception log to obtain updated values ​​for the PID algorithm operation weights. By adjusting the PID algorithm operation weights, the purpose of reducing the fluctuation amplitude and frequency of the output voltage curve is achieved, thereby improving output stability.

[0049] It is worth mentioning that it also includes: Real-time monitoring of the output voltage transient change rate at the moment of power switching; If the transient change rate exceeds a preset safety threshold, the CPLD is immediately triggered to generate a voltage slow start control signal; The MOSFET gate capacitor in the first power switch module or the second power switch module is driven by the slow start control signal, so that the output voltage slowly rises to the target value in the form of an exponential curve.

[0050] It should be noted that in this embodiment, when a power switching instruction is issued through the CPLD, the high-speed voltage sampling circuit immediately monitors the transient change rate of the voltage at the power output end at a frequency of microseconds. The transient protection algorithm built into the CPLD compares the change rate with the preset safety threshold in real time. If a transient overshoot risk is detected, such as the capacitor charging too quickly causing the change rate to exceed the standard, the CPLD immediately generates a slow-start digital pulse sequence. The slow-start pulse is input to the MOSFET driver chip of the power switch module to control the charging current slope of the MOSFET gate capacitance. The gate voltage then slowly rises in an exponential curve, and eventually the output voltage is smoothly ramped to the target value. The CPLD continuously verifies the stability of the output voltage until the transient change rate drops below the safety threshold and then exits the protection mode.

[0051] It is worth mentioning that it also includes: Obtaining the real-time load current and ambient temperature of the voltage regulation module; Based on the preset three-dimensional compensation model, the voltage regulation compensation coefficient under the current working conditions is obtained; adding the compensation coefficient to the first voltage regulation parameter to generate a dynamically optimized second voltage regulation parameter; If the first deviation information does not converge after N consecutive updates, the redundant voltage regulation strategy in the three-dimensional compensation model is switched to and an alarm is issued.

[0052] It should be noted that during the operation of the voltage regulation module, a high-precision Hall current sensor collects load current data in real time, while a temperature sensor monitors the heat sink temperature. Both data are converted by ADC and input into the processor. Based on the preset voltage-current-temperature three-dimensional compensation model, a lookup table method or linear interpolation algorithm is used to match the optimal compensation coefficient according to the current current value and temperature value. The compensation coefficient is superimposed on the original voltage regulation parameter to generate a dynamic optimization parameter, which is configured to the voltage regulation module. At the same time, the deviation between the output voltage and the target value is calculated. If the deviation still exceeds the preset deviation threshold after three consecutive adjustments, it is determined that the model has failed and automatically switches to the redundant voltage regulation strategy. As an implementation method, the PWM duty cycle is fixed to 50% and forced air cooling is started. At the same time, the voltage regulation fault code is sent to the background and an alarm is triggered, and the current, temperature and parameter adjustment sequence are recorded in the non-volatile memory for fault analysis.

[0053] Figure 5 The block diagram of the compatible system of the multi-voltage adapter based on Feiteng D3000 of the present invention is shown.

[0054] like Figure 5 As shown, the second aspect of the present invention discloses a compatible system 5 for a multi-voltage adapter based on Feiteng D3000, comprising a memory 51 and a processor 52. The memory includes a compatible method program for a multi-voltage adapter based on Feiteng D3000. When the compatible method program for a multi-voltage adapter based on Feiteng D3000 is executed by the processor, the following steps are implemented: detecting a DC voltage input by the adapter to obtain first voltage information; Based on a preset voltage threshold comparison logic, generating a first switch control signal according to the first voltage information; determining whether the first switch control signal is a first power-on signal; If yes, turning on the first power supply and obtaining second voltage information according to the first voltage information; If not, turning on the second power supply, configuring the first voltage regulation parameter of the voltage regulation module based on a preset voltage regulation logic, and obtaining the second voltage information according to the first voltage information; Based on a preset confidence setting logic, obtaining first confidence information according to the second voltage information; Determining whether the first confidence information exceeds a preset first confidence threshold; If so, the first voltage regulation parameter is adjusted or a redundant protection mechanism is triggered.

[0055] It should be noted that the first voltage information is the input voltage value of the compatible circuit of the multi-voltage adapter, that is, the DC voltage value input by the adapter; the first switch control signal is a logic control signal used to drive the first power switch module and the second power switch module; the second voltage information is the output voltage value of the compatible circuit of the multi-voltage adapter; the first voltage regulation parameter is a control parameter used to adjust the output state of the voltage regulation module; and the first confidence information is used to determine that the output voltage is in an abnormal state.

[0056] In this embodiment, first, by detecting the DC voltage input by the adapter, first voltage information, i.e., the input voltage, is obtained. Then, based on the comparison of the input voltage value with a preset voltage threshold range, a corresponding first switch control signal is generated to drive the corresponding power switch module to select the power path. When the first power source is connected, the output voltage is directly output based on the first power source. When the second power source is connected, the first voltage regulation parameter of the voltage regulation module is configured using a preset voltage regulation logic to obtain the output voltage. This achieves compatibility with multiple voltage adapters. Furthermore, based on a preset confidence setting logic, the voltage curve of the output voltage is analyzed to obtain the probability of being in an abnormal state, i.e., the abnormality confidence level. When the abnormality confidence level exceeds the preset first confidence threshold, it indicates the presence of an abnormality. In this case, the voltage regulation module is adjusted to reduce the output voltage or limit the output current, or a redundant protection mechanism is triggered to form multiple protections, thereby improving the reliability and safety of the product.

[0057] According to an embodiment of the present invention, the first switch control signal is generated according to the first voltage information based on the preset voltage threshold comparison logic, specifically: Determining whether the first voltage information is within a preset first voltage threshold range; If yes, generating a first switch control signal according to the first power-on signal; If not, determining whether the first voltage information is within a preset second voltage threshold range; If yes, generating a first switch control signal according to the second power-on signal, and setting the device to enter the first voltage regulation mode; If not, a first switch control signal is generated according to the third power-on signal to set the device to enter the second voltage regulation mode.

[0058] It should be noted that the first power-on signal is used to drive the first power switch module to turn on the first power supply; the second power-on signal is used to drive the second power switch module to turn on the second power supply and to set the device to enter the first voltage regulation mode; the third power-on signal is used to drive the second power switch module to turn on the second power supply and to set the device to enter the second voltage regulation mode.

[0059] In this embodiment, the operating process of the voltage threshold comparison logic provided is specifically as follows: if the first voltage information is within a preset first voltage threshold range, a first switch control signal is generated according to a first power-on signal; if the first voltage information is within a preset second voltage threshold range, a first switch control signal is generated according to the second power-on signal, and the first voltage regulation mode is set to be entered.

[0060] As an implementation method, for example, in a 12V FT D3000 power supply system, if the input voltage is within the range of [11.5V, 12.5V], it means that a 12V adapter is connected. At this time, the first switch control signal is set to the first power-on signal. If the input voltage is within the range of [18V, 20V] or [22.5V, 25.5V], it means that a 19V or 24V adapter is connected. At this time, the first switch control signal is set to the second power-on signal, and the first voltage regulation mode is entered. If the input voltage is not within the above range, it means that a non-standard voltage adapter is connected. At this time, the first switch control signal is set to the third power-on signal, and the second voltage regulation mode is entered. The above process can achieve the purpose of compatibility with multiple voltage adapters.

[0061] According to an embodiment of the present invention, configuring the first voltage regulation parameter of the voltage regulation module based on the preset voltage regulation logic and obtaining the second voltage information according to the first voltage information is specifically as follows: Determining whether to enter the first voltage regulation mode; If yes, setting the first voltage regulation parameter according to a preset first voltage regulation reference value; If not, query the historical voltage regulation parameters and set the first voltage regulation parameters; The voltage regulation module is configured according to the first voltage regulation parameter to obtain second voltage information.

[0062] It should be noted that this embodiment provides a flow chart for operating the voltage regulation logic. Entering the first voltage regulation mode indicates that a standard adapter (19V or 24V) is connected. In this case, the voltage regulation reference values ​​corresponding to the standard adapter are used to set the first voltage regulation parameters. Otherwise, this indicates that a non-standard adapter is connected. In this case, the first voltage regulation parameters are set based on the most recent voltage regulation parameters from the historical voltage regulation parameters. By selecting the first voltage regulation parameters in this manner, the time required to adjust the input voltage to the target voltage is minimized, thereby improving voltage regulation speed.

[0063] According to an embodiment of the present invention, the further embodiment includes: Calculating a difference between the second voltage information and preset target voltage information to obtain first deviation information; Based on a preset feedback adjustment algorithm, the first voltage adjustment parameter is updated according to the first deviation information; configuring the voltage regulation module according to the first voltage regulation parameter and updating the second voltage information; The first voltage information and the first voltage regulation parameter are recorded and stored.

[0064] It should be noted that the target voltage information is the target value of the output voltage after voltage regulation. In this embodiment, a feedback regulation algorithm is used to control the voltage regulation module to output the target voltage value. As an implementation method, the feedback regulation operation is implemented using a PID algorithm. First, the deviation between the current output voltage and the target output voltage is calculated; then, the deviation value is passed to the PID algorithm to obtain a regulation variable, which is used to update the first voltage regulation parameter; finally, the updated regulation variable is configured in the voltage regulation module to achieve the purpose of adjusting the output voltage. In addition, the input voltage and the first voltage regulation parameter of the voltage regulation module are recorded and stored as historical voltage regulation parameters.

[0065] According to an embodiment of the present invention, the first confidence information is obtained according to the second voltage information based on the preset confidence setting logic, specifically: obtaining a voltage curve according to the second voltage information; According to the voltage curve, obtaining a fluctuation amplitude of the second voltage information when the second voltage information is in a steady state stage; Based on a preset fluctuation range, the first confidence information is updated according to the fluctuation amplitude.

[0066] It should be noted that in this embodiment, an operational process for the confidence setting logic is provided. When the output voltage is in a steady-state phase, the output voltage fluctuation amplitude is collected; wherein, the steady-state phase is the period within a preset time window in which the average value of the output voltage is within the target voltage range. Then, based on the relationship between the fluctuation amplitude and the fluctuation range, the first confidence information is updated. As an embodiment, when the fluctuation amplitude exceeds the preset fluctuation range, the first confidence information is adjusted upward; when several consecutive obtained fluctuation amplitudes are within the preset fluctuation range, the first confidence information is adjusted downward.

[0067] According to an embodiment of the present invention, the further embodiment includes: When determining that the redundant protection mechanism is triggered; An abnormality log is generated and stored according to the voltage curve, the fluctuation amplitude and the first voltage regulation parameter.

[0068] It should be noted that when the redundant protection mechanism is triggered, an audio / visual prompt will be generated. As an implementation, in systems with a backup power supply, the input power source will be switched to the backup power source. In addition, an abnormality log will be generated based on the output voltage curve, voltage fluctuation amplitude, and the first voltage regulation parameters for subsequent query and analysis.

[0069] It is worth mentioning that it also includes: When the first power supply or the second power supply is turned on, obtaining first current information; Obtaining a current change rate according to the first current information; If the current change rate exceeds a preset change rate threshold, the first power switch module or the second switch module is driven to enter a slow shutdown mode.

[0070] It should be noted that the first current information is the real-time current value when the first power switch module or the second switch module performs a switching action. In this embodiment, a slow shutdown operation process is provided. During the power switching operation, if the rate of change of the switching current exceeds a preset rate of change threshold, it indicates that there is a sudden change in the current and there is an abnormal risk. At this time, the CPLD module drives the first power switch module or the second switch module to enter the slow shutdown mode, and by adjusting the delay time of the delay circuit, it plays a role in protecting the device.

[0071] It is worth mentioning that it also includes: When it is determined that the second power supply is turned on; Acquiring temperature information of the voltage regulation module; Determining whether the temperature information exceeds a preset temperature threshold; If so, the voltage regulation module is configured to enter the current limiting mode.

[0072] It should be noted that this embodiment provides an over-temperature protection process. When the temperature of the voltage regulator module exceeds a preset temperature threshold, to ensure the operational reliability of the voltage regulator module and the entire circuit system, it will enter current limiting mode, reducing the current output to achieve the purpose of cooling.

[0073] It is worth mentioning that it also includes: Sending the exception log to a preset exception processing neural network model to obtain feedback adjustment weights; The operation weight of the feedback adjustment algorithm is updated according to the feedback adjustment weight.

[0074] It should be noted that in this embodiment, the exception processing neural network model also analyzes the exception log to obtain updated values ​​for the PID algorithm operation weights. By adjusting the PID algorithm operation weights, the purpose of reducing the fluctuation amplitude and frequency of the output voltage curve is achieved, thereby improving output stability.

[0075] It is worth mentioning that it also includes: Real-time monitoring of the output voltage transient change rate at the moment of power switching; If the transient change rate exceeds a preset safety threshold, the CPLD is immediately triggered to generate a voltage slow start control signal; The MOSFET gate capacitor in the first power switch module or the second power switch module is driven by the slow start control signal, so that the output voltage slowly rises to the target value in the form of an exponential curve.

[0076] It should be noted that in this embodiment, when a power switching instruction is issued through the CPLD, the high-speed voltage sampling circuit immediately monitors the transient change rate of the voltage at the power output end at a frequency of microseconds. The transient protection algorithm built into the CPLD compares the change rate with the preset safety threshold in real time. If a transient overshoot risk is detected, such as the capacitor charging too quickly causing the change rate to exceed the standard, the CPLD immediately generates a slow-start digital pulse sequence. The slow-start pulse is input to the MOSFET driver chip of the power switch module to control the charging current slope of the MOSFET gate capacitance. The gate voltage then slowly rises in an exponential curve, and eventually the output voltage is smoothly ramped to the target value. The CPLD continuously verifies the stability of the output voltage until the transient change rate drops below the safety threshold and then exits the protection mode.

[0077] It is worth mentioning that it also includes: Obtaining the real-time load current and ambient temperature of the voltage regulation module; Based on the preset three-dimensional compensation model, the voltage regulation compensation coefficient under the current working conditions is obtained; adding the compensation coefficient to the first voltage regulation parameter to generate a dynamically optimized second voltage regulation parameter; If the first deviation information does not converge after N consecutive updates, the redundant voltage regulation strategy in the three-dimensional compensation model is switched to and an alarm is issued.

[0078] It should be noted that during the operation of the voltage regulation module, a high-precision Hall current sensor collects load current data in real time, while a temperature sensor monitors the heat sink temperature. Both data are converted by ADC and input into the processor. Based on the preset voltage-current-temperature three-dimensional compensation model, a lookup table method or linear interpolation algorithm is used to match the optimal compensation coefficient according to the current current value and temperature value. The compensation coefficient is superimposed on the original voltage regulation parameter to generate a dynamic optimization parameter, which is configured to the voltage regulation module. At the same time, the deviation between the output voltage and the target value is calculated. If the deviation still exceeds the preset deviation threshold after three consecutive adjustments, it is determined that the model has failed and automatically switches to the redundant voltage regulation strategy. As an implementation method, the PWM duty cycle is fixed to 50% and forced air cooling is started. At the same time, the voltage regulation fault code is sent to the background and an alarm is triggered, and the current, temperature and parameter adjustment sequence are recorded in the non-volatile memory for fault analysis.

[0079] The third aspect of the present invention provides a computer-readable storage medium, which includes a compatibility method program for a multi-voltage adapter based on Feiteng D3000. When the compatibility method program for a multi-voltage adapter based on Feiteng D3000 is executed by a processor, the steps of the compatibility method for a multi-voltage adapter based on Feiteng D3000 as described in any one of the above items are implemented.

[0080] In summary, the present invention provides a compatibility method, system, and medium for a multi-voltage adapter based on Feiteng D3000. First, based on the first voltage information input by the adapter, a first switch control signal is generated based on a preset voltage threshold comparison logic; then, based on the first switch control signal, the corresponding power path is connected to obtain the second voltage information, wherein, for the second power path, based on the preset voltage regulation logic, the first voltage regulation parameter is configured to obtain the second voltage information; finally, based on the preset confidence setting logic, the first confidence information is obtained according to the second voltage information to determine whether to trigger a redundant protection mechanism. The present invention solves the compatibility problem of the product through voltage detection and logical decision-making, and also forms multiple protections through dynamic voltage regulation and redundant protection to improve the reliability and safety of the product.
