[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to the Chinese patent application filed with the China Patent Office on November 29, 2023, with application number 202311611573.3, and application name “A Power Supply System and Electronic Device”, all contents of which are incorporated by reference into this application. Technical Field

[0003] The present application relates to the field of power supply technology, and in particular to a power supply system and electronic equipment. Background Art

[0004] The era of big data places higher demands on the reliability and efficiency of equipment. The power supply system can provide power to each load unit on the equipment. In practical applications, the corresponding load units can be deployed according to the required functions of the equipment. To ensure the stable and reliable power supply provided by the power supply system to the load units and the safe operation of the power supply system without downtime, backup power protection methods such as backup power supply units (Battery Battery Units, BBUs) are often used. Board-level power supplies use dual power modules for redundant power supply to power the load units. However, this implementation method does not undergo logical problem analysis and judgment, and cannot provide the optimal solution within a short period of time when a load unit power supply anomaly occurs, let alone fundamentally correct the load unit power supply anomaly. In addition, the dual power supply method of using one active and one backup in the board-level power supply results in cost waste and also leads to current sharing issues.

[0005] For high-speed link load units in power supply systems, such as high-speed network cards, serial link cards, and Fibre Channel (FC) cards, as network card performance continues to improve, data transmission rates have also increased to 32G or even 64G. High-speed links are easily affected by environmental interference or performance anomalies, resulting in card loss and interruption of business data processing.

[0058] The following will be combined with the accompanying drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0059] The terms "including" and "having," as well as any variations thereof, in the specification and claims of this application and the accompanying drawings, are intended to cover a non-exclusive inclusion. For example, a process, method, system, product, or apparatus comprising a series of steps or elements is not limited to the listed steps or elements and may include steps or elements that are not listed.

[0060] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0061] Next, a power supply system provided by an embodiment of the present application is described in detail. The power supply system provided by an embodiment of the present application can be applied to heat dissipation equipment, computers, servers, switch units, etc. Figure 1 is a schematic structural diagram of a power supply system provided by an embodiment of the present application, which includes a monitoring unit 11, a control unit 12, a double-layer capacitor 13, a first power supply unit 14, and a second power supply unit 15.

[0062] Among them, the first power supply unit 14 includes a plurality of voltage converters, each of which is connected to its corresponding load unit 16. The second power supply unit 15 includes a plurality of voltage divider components, each of which is connected to its corresponding next-level load unit 16 through a voltage divider component. The monitoring unit 11 is connected to the load unit 16, and the monitoring unit 11 is used to obtain the status information of each load unit 16 and transmit each status information to the control unit 12. The control unit 12 is respectively connected to the double-layer capacitor 13, the first power supply unit 14 and the second power supply unit 15. The control unit 12 is used to: receive each status information transmitted by the monitoring unit 11, and in response to determining that the status information of the target load unit 16 is abnormal, control the voltage divider component connected to the target load unit 16 to be turned on, and use the double-layer capacitor 13 to supplement the power supply to the target load unit 16.

[0063] In practical applications, the status information of each load unit 16 may include a voltage value. When the power supply of a load unit 16 is abnormal, its voltage value will change. Therefore, in the embodiment of the present application, the power supply abnormality can be detected in a timely manner by monitoring the voltage value of each load unit 16.

[0064] In the embodiment of the present application, the monitoring unit 11 can obtain the voltage value of each load unit 16 and transmit each voltage value to the control unit 12. After receiving the voltage values ​​transmitted by the monitoring unit 11, the control unit 12 can determine whether each voltage value is abnormal. In response to determining that the target voltage value corresponding to the target load unit 16 is abnormal, the control unit 12 controls the voltage divider connected to the target load unit 16 to conduct, and uses the double-layer capacitor 13 to supplement the power supply to the target load unit 16.

[0065] In actual applications, the voltage value of each load unit 16 under normal power supply status can be recorded in the memory. For the sake of distinction, the voltage value under normal power supply status can be referred to as the theoretical voltage value. In implementation, the control unit 12 can read the theoretical voltage value corresponding to each load unit 16 under normal power supply status from the memory. It is determined whether the voltage value corresponding to each load unit 16 matches its theoretical voltage value. In the case where the voltage value of the target load unit 16 does not match its theoretical voltage value, it means that the power supply of the target load unit 16 is abnormal. In order to ensure the stability of the business on the target load unit 16, the control unit 12 can control the voltage divider connected to the target load unit 16 to be turned on. At this time, the upper-level voltage converter of the target load unit 16 is connected to the target load unit through the voltage divider, thereby realizing short-term power supply to the target load unit 16.

[0066] Furthermore, in order to ensure that the previous voltage converter will not be overloaded due to power replenishment, when the double-layer capacitor 13 meets the discharge conditions, the double-layer capacitor 13 can be used to supplement the power supply to the target load unit 16, and the voltage divider connected to the target load unit 16 can be switched to the disconnected state.

[0067] The double-layer capacitor 13, also known as a supercapacitor, has the characteristics of short charging time and long service life. Its starting efficiency and reliability are higher than those of traditional batteries, and it can be used as a supplementary power supply for the load unit 16. The double-layer capacitor 13 can be a supercapacitor with a capacity of 1F. In the initial state, the first power supply unit 14 can charge the double-layer capacitor 13, and the double-layer capacitor 13 enters a static state after being fully charged. After the double-layer capacitor 13 is fully charged, it has a corresponding full-charge voltage value. In actual application, it can be determined whether the voltage value of the double-layer capacitor 13 is equal to the full-charge voltage value. When the voltage value of the double-layer capacitor 13 is equal to the full-charge voltage value, it means that the double-layer capacitor 13 meets the discharge conditions.

[0068] In the embodiment of the present application, when the voltage value of the target load unit 16 does not match its theoretical voltage value, it indicates that a power supply abnormality has occurred in the target load unit 16. In addition to supplying additional power to the target load unit 16, the treatment method for the target load unit 16 can be further determined based on the power supply time that the double-layer capacitor 13 can support. There are two possible treatment methods: one is to repair the target load unit 16, and the other is to back up the target load unit 16.

[0069] In actual applications, the monitoring unit 11 can transmit the read capacitance value of the double-layer capacitor 13, the recharging voltage value of the double-layer capacitor 13, and the load current value of the target load unit 16 to the control unit 12 when the voltage value of the target load unit 16 does not match its theoretical voltage value. The control unit 12 determines the recharging time based on the received capacitance value of the double-layer capacitor 13, the recharging voltage value of the double-layer capacitor 13, and the load current value of the target load unit 16. If the recharging time is greater than the power supply anomaly repair time, it means that the power of the double-layer capacitor 13 can support the target load unit 16 to complete the repair, and the target load unit 16 can be repaired at this time.

[0070] In practical applications, the control unit 12 may multiply the capacitance of the double-layer capacitor 13 by the charging voltage of the double-layer capacitor 13 , and divide the product by the load current of the target load unit 16 to obtain the charging time.

[0071] The calculation formula for the charging time is as follows: T=C*U / I;

[0072] Wherein, T represents the charging time, C represents the capacitance value of the double-layer capacitor, U represents the charging voltage value of the double-layer capacitor, and I represents the load current value of the target load unit.

[0073] In an embodiment of the present application, the repair times corresponding to different types of power supply anomalies can be recorded in a non-volatile memory. In response to determining that a power supply anomaly has occurred in the target load unit 16, the monitoring unit 11 can identify the type of power supply anomaly of the target load unit 16 by obtaining log information of the target load unit 16. Based on the power supply anomaly type, the corresponding repair time can be obtained from the non-volatile memory. For ease of distinction, this repair time can be referred to as the power supply anomaly repair time.

[0074] In response to determining that the recharging time is greater than the power supply anomaly repair time, the target load unit 16 may be repaired. To determine the cause of the power supply anomaly, the monitoring unit 11 may read the potential value of each pin of the target load unit 16 and transmit the potential value of each pin of the target load unit 16 to the control unit 12.

[0075] The target load unit 16 has a large number of pins. In practical applications, only the potential values ​​of power-related pins may be obtained, wherein the power-related pins may include feedback pins, compensation pins, protection pins, and bootstrap pins.

[0076] After receiving the potential values ​​of each pin of the target load unit 16 transmitted by the monitoring unit 11, the control unit 12 can read the theoretical potential values ​​of each pin of the target load unit 16 under normal power supply conditions from the memory. If the target potential value of a target pin is inconsistent with its target theoretical potential value, it indicates that there is a problem with the power supply of the target pin. In this case, the potential value of the target pin can be adjusted to the target theoretical potential value.

[0077] When the recharging time is less than or equal to the power supply abnormality repair time, it means that the power of the double-layer capacitor 13 cannot support the target load unit 16 to complete the repair. In this case, in order to ensure the normal processing of business data, the target load unit 16 can be backed up.

[0078] In actual applications, a power supply system includes at least two controllers, and load units 16 with the same functions are deployed on different controllers. Taking two controllers as an example, the two controllers are mutually controlled devices. For example, controller A and controller B, controller A is the controlled device of controller B, and controller B is the controlled device of controller A. The backup of the target load unit 16 can be to transfer the business data of the target load unit 16 to the corresponding load unit on the controlled device. By transferring the business data of the target load unit 16 to the corresponding load unit on the controlled device, although the data processing efficiency will be reduced, the uninterrupted processing of business data can be guaranteed, and the business can still be executed normally.

[0079] In an embodiment of the present application, a baseboard management controller (BMC) may be provided. The monitoring unit 11 is connected to the BMC and is configured to transmit an alarm message to the BMC in response to determining that the voltage value of the target load unit 16 does not match its theoretical voltage value, and trigger the BMC to record an abnormality log.

[0080] In addition to power supply anomalies, in actual applications, when power supply is normal, the load unit 16 may have high-speed link load communication anomalies. In the embodiment of the present application, the monitoring unit 11 can obtain the load communication data of each load unit 16 and transmit the load communication data to the control unit 12.

[0081] The processing method of each load unit 16 is similar. For the convenience of description, one target load unit 16 is used as an example for explanation.

[0082] In response to determining that the target voltage value of the target load unit 16 is normal, the control unit 12 may determine whether the load communication data corresponding to the target load unit 16 is abnormal after receiving the load communication data of each load unit 16 transmitted by the monitoring unit 11 .

[0083] When the target load communication data corresponding to the target load unit 16 is abnormal and the target voltage value is normal, it means that the target load unit 16 currently has a high-speed link load communication abnormality, but has not stopped working or lost the card or data. In order to avoid the storage power supply coefficient from being down due to the target load unit stopping working or losing the card or data, the business data on the abnormal target load unit 16 can be backed up in advance.

[0084] In actual applications, the business data of the target load unit 16 can be transferred to the corresponding load unit on the control device. After receiving the business data, the corresponding load unit on the control device can process the business data, set a mark for the processed new business data, and cache it in the memory.

[0085] By setting a mark on the new service data, the control unit 12 can distinguish which data is generated due to service transfer. In addition, caching the new service data in the memory can facilitate fast access to the new service data.

[0086] When a high-speed link load communication anomaly occurs on the target load unit 16, the processing of service data on the target load unit 16 can be separated from the load link of the target load unit 16, and the service data can be distributed to the corresponding load unit on the controlled device for execution. At this time, the control unit 12 can send a reset signal to the target load unit 16, so that the target load unit 16 can restart based on the reset signal.

[0087] The monitoring unit 11 can monitor the target load communication data of the target load unit 16 and transmit the target load communication data to the control unit 12. After receiving the target load communication data, the control unit 12 can determine whether the target load communication data has returned to normal. If the target load communication data is normal, it indicates that the target load unit 16 can resume processing service data. At this time, the control unit 12 can read the marked new service data from the memory and send the marked new service data to the target load unit 16. After receiving the marked new service data, the target load unit 16 can process the marked new service data and store the processing results to the hard disk.

[0088] The monitoring unit 11 can be used to obtain the voltage value and load communication data of the load unit 16. In actual applications, the monitoring unit 11 can obtain the voltage value of each load unit 16 through multiple sampling pins and obtain the load communication data of each load unit 16 through multiple serial bus (Inter Integrated Circuit, I2C) links.

[0089] The monitoring unit 11 stores the voltage value and load communication data of each load unit 16 in the non-volatile memory, and updates the data recorded in the non-volatile memory according to the voltage value and load communication data of each load unit 16 read in real time.

[0090] Considering the limited storage space of the non-volatile memory, in order to ensure the availability of the non-volatile memory, the available storage space of the non-volatile memory can be monitored. The monitoring unit 11 can detect the available storage space of the non-volatile memory. If the available storage space of the non-volatile memory is less than a set threshold, the data recorded in the non-volatile memory is deleted based on the data storage time.

[0091] The threshold value can be determined based on the total storage space of the non-volatile memory and the proportion of the reserved emergency space in the total storage space. For example, 80% of the capacity can be used for data storage, and 20% of the capacity can be used as emergency space. Generally, the emergency space does not store data. Assuming that the total storage space of the non-volatile memory is 512KB, the threshold value can be set to 512 * 20% = 102.4KB. If the available storage space in the non-volatile memory is less than 102.4KB, the data stored in the non-volatile memory the longest can be deleted.

[0092] In the embodiments of the present application, by recording the load unit's voltage value and load communication data in non-volatile memory, the controller can easily understand the load unit's operating status. By updating the data recorded in the non-volatile memory in real time, the non-volatile memory is guaranteed to store the latest voltage value and load communication data. Furthermore, by monitoring the available storage space in the non-volatile memory, the non-volatile memory is ensured to be always available, improving the reliability of data storage.

[0093] In the embodiment of the present application, the first power supply unit 14 may be a multi-channel voltage converter. Considering that different types of load units 16 require different supply voltages, the supply voltage of the multi-channel voltage converter can be set based on the power supply requirements of the load units 16.

[0094] In the embodiment of the present application, a second power supply unit 15 is provided to realize the downward compatible power supply of the multi-channel voltage converter. The second power supply unit 15 may include a multi-channel voltage dividing component.

[0095] Each voltage dividing component may include a switch component and a voltage dividing resistor, wherein the switch component may be a transistor (Metal Oxide Semiconductor, MOS).

[0096] In practical applications, the supply voltages of multiple voltage converters can be divided in sequence according to the power supply levels of the load units 16 , and the supply voltage of each voltage converter is equal to the load voltage of its corresponding load unit 16 and higher than the load voltage of the next level load unit 16 .

[0097] For example, the power supply levels can be divided into: 5V, 3.3V, 2.5V, 1.8V, 1.2V and below 1V. Each power supply level can correspond to one or more voltage converters. For ease of description, the voltage converter corresponding to the power supply level below 1V can be called the first power supply unit of this level, the voltage converter corresponding to the power supply level of 1.2V can be called the first power supply unit of the previous level, and the voltage converter corresponding to the power supply level of 1.8V can be called the first power supply unit of the previous two levels, and so on. The voltage converters corresponding to different power supply levels can be named by level.

[0098] The second power supply unit 15 and the double-layer capacitor 13 are used to provide a compatible power supply to the load unit when a power supply anomaly occurs on the load unit. The double-layer capacitor 13 can also provide supplementary power to the load unit with the current power supply anomaly.

[0099] The backward compatible power supply provided by each voltage converter in the first power supply unit 14 means that when the 3.3V power supply experiences an anomaly, 5V power is used to provide short-term supplemental power. When the 2.5V power supply experiences an anomaly, 3.3V power is used to provide short-term supplemental power. Similarly, when power supply anomalies below 1V occur, 1.2V power is used to provide supplemental power.

[0100] When the control unit 12 detects that the power supply of the load unit 16 is abnormal, on the one hand, the control unit 12 promptly provides a conduction signal to the MOS connected to the previous voltage converter of the abnormal load unit 16. At this time, the previous voltage converter simultaneously supplies power to the original load unit and provides power to the abnormally powered load unit, ensuring that the operation of the abnormally powered load unit will not be abnormal in a short period of time, thereby leaving a certain amount of discharge preparation time for the double-layer capacitor. On the other hand, the monitoring unit 11 can record the status of the group of load units and provide it to the control unit 12, so that the control unit 12 can determine the power replenishment time based on the capacitance value of the double-layer capacitor, the power replenishment voltage value of the double-layer capacitor, and the load current value of the load unit with abnormal power supply. The measures to be taken are determined based on the length of the power replenishment time.

[0101] Each voltage converter is processed similarly. Taking any one of the voltage converters as an example, the connection relationship and operation of that voltage converter will be described in detail. For ease of distinction, this voltage converter can be referred to as the first voltage converter. The switch component connected to the first voltage converter is referred to as the first switch component, and the load unit 16 directly connected to the first voltage converter is referred to as the first load unit. The voltage divider resistor connected to the first switch component is referred to as the first voltage divider resistor, and the load unit 16 connected to the first voltage divider resistor is referred to as the second load unit.

[0102] In practical applications, a first voltage converter is connected to its corresponding first load unit. The first voltage converter is connected to a second load unit via a first switch component and a first voltage divider resistor. The supply voltage of the first voltage converter is equal to the load voltage of the first load unit and higher than the load voltage of the second load unit. The resistance value of the first voltage divider resistor is set based on the supply voltage of the first voltage converter, the load voltage of the second load unit, and the load current. The first voltage converter is any one of a plurality of voltage converters.

[0103] The control unit 12 controls the connection and disconnection between the voltage converter and the next-stage load unit by controlling the on and off of the switch component. The switch component can be of various types, such as a field-effect transistor (MOS) or a transistor. For ease of description, the following description uses a transistor as an example.

[0104] FIG2 is a schematic diagram of the connection relationship of a second power supply unit provided in an embodiment of the present application. FIG2 takes two voltage-dividing components as an example, and both voltage-dividing components include transistors and voltage-dividing resistors. Considering the difference in the voltage-dividing values ​​required to be achieved by the two voltage-dividing components, the resistance values ​​of the two voltage-dividing resistors in FIG2 may be different, and are represented by voltage-dividing resistor 1 and voltage-dividing resistor 2 in FIG2 , respectively. For ease of distinction, the transistor connected to voltage-dividing resistor 1 may be referred to as transistor 1, and the transistor connected to voltage-dividing resistor 2 may be referred to as transistor 2.

[0105] In Figure 2, the first power supply unit of this stage is directly connected to load unit a. The first power supply unit of the previous stage is directly connected to load unit b. To achieve backward compatibility, the first power supply unit of the previous stage connects to load unit a via transistor 1 and voltage divider resistor 1, and the first power supply units of the previous two stages connect to load unit b via transistor 2 and voltage divider resistor 2. Taking Figure 2 as an example, for the first power supply unit of the previous stage, load unit a is equivalent to the load unit of this stage, and load unit b is equivalent to the load unit of the next stage.

[0106] In the initial state, all transistors can be in the off state. When a power supply anomaly occurs in a load unit, the control unit 12 can control the transistor connected to the load unit to conduct. For example, when the control unit detects a power supply anomaly in load unit a, it can control transistor 1 to conduct. At this time, the link between the first power supply unit of the previous stage and load unit a is in the conducting state, and the first power supply unit of the previous stage can replenish power to load unit a.

[0107] In conjunction with the above example, the previous-stage first power supply unit originally needs to supply power to load unit b. If the previous-stage first power supply unit supplies power to load unit a for a long time on this basis, the previous-stage first power supply unit may be overloaded. Therefore, in the embodiment of the present application, after the double-layer capacitor 13 is discharged and ready to supply power to load unit a, the control unit can control the transistor 1 to switch to the off state. At this time, the previous-stage first power supply unit only needs to supply power to load unit b, thereby ensuring that the previous-stage first power supply unit will not be overloaded due to supplying power to load unit a.

[0108] In an embodiment of the present application, a voltage divider component is provided between the voltage converter and the load unit, so that the voltage converter can not only supply power to the originally connected load unit, but also provide supplementary power supply to the next-level load unit, so that when a power supply abnormality occurs in the load unit, power can be supplemented in time to ensure normal processing of the business.

[0109] In an embodiment of the present application, a microcontroller unit (MCU) can be used as the monitoring unit 11. The monitoring unit 11 can include two parts: a potential monitoring unit and a communication monitoring unit. The MCU provides multiple sampling pins that can read the current voltage value of the load unit 16 in a timely manner. The MCU also provides multiple I2C pins that can read the current load communication data in real time via the I2C link. The MCU can access and update the currently read data in real time, continuously updating the current pin potential value and load communication data.

[0110] The MCU can be an STMicroelectronics module (STM32F446RCT6TR), which provides four I2C interfaces for acquiring load communication data. This allows control unit 12 to evaluate the normal operation of the high-speed link load communication based on the load communication data. The MCU also provides 24 ADC pins for voltage detection and 512KB of memory for data storage.

[0111] The control unit 12 can be centered around a Complex Programmable Logic Device (CPLD) to control the voltage converter's backward-compatible power supply and the functional repair or backup of abnormal load units. The logic control unit can utilize an integrated circuit module (LCMXO3LF-9400C-5BG484C), which provides 1175 logic array blocks (LABs) and supports the simultaneous operation of a large number of logic resources. This allows for efficient power supply control and state repair during power supply anomalies.

[0112] The first power supply unit 14 is the power supply core of the power supply system. The first power supply unit 14 includes a multi-channel DC converter (DCDC) voltage converter. The voltage converter can adopt a high-frequency synchronous buck converter (MPQ8633A). The MPQ8633B can provide a current output of 20A and a voltage output of 0.6V to 5.5V, which can cover most power supply situations of the current board-level power supply.

[0113] It can be seen from the above technical solution that the power supply system includes a monitoring unit, a control unit, a double-layer capacitor, a first power supply unit, and a second power supply unit. Among them, the first power supply unit includes a multi-channel voltage converter. Each voltage converter is connected to its corresponding load unit. The second power supply unit includes a multi-channel voltage divider component. Each voltage converter is connected to its corresponding next-level load unit through a voltage divider component. The monitoring unit is connected to the load unit, and the monitoring unit is used to obtain the status information of each load unit and transmit each status information to the control unit. The control unit is connected to the double-layer capacitor, the first power supply unit, and the second power supply unit respectively. The control unit is used to receive each status information transmitted by the monitoring unit, and in response to determining that the status information of the target load unit is abnormal, controls the voltage divider component connected to the target load unit to conduct, and uses the double-layer capacitor to supplement power to the target load unit. The beneficial effect of this application is that voltage compatibility can be achieved by cooperating with the first power supply unit through the second power supply unit, so that in addition to supplying power to its corresponding load unit, the first power supply unit can also provide the required voltage to the next-level load unit via the second power supply unit when the next-level load unit has power supply needs. The double-layer capacitor can achieve supplementary power supply to the load unit with abnormal power supply. Even when a power supply abnormality occurs in a load unit, short-term redundant power supply to the abnormal load unit can be achieved through double-layer capacitors and voltage compatibility, avoiding system downtime caused by power supply abnormality, ensuring the stability of business data processing, and increasing the reliability of the power supply system.

[0121] FIG4 is a flow chart of a method for providing supplementary power to a load unit with abnormal power supply, provided in an embodiment of the present application, which includes:

[0122] S401: Reading the theoretical voltage value corresponding to each load unit under the normal power supply state from the memory.

[0123] In practical applications, the voltage value of each load unit under normal power supply status may be recorded in a memory. For ease of distinction, the voltage value under normal power supply status may be referred to as a theoretical voltage value.

[0124] S402: Determine whether the voltage value corresponding to each load unit matches its theoretical voltage value.

[0125] In implementation, the control unit may read the theoretical voltage value corresponding to each load unit in the normal power supply state from the memory, determine whether the voltage value corresponding to each load unit matches its theoretical voltage value, and execute S403 in response to determining that the voltage value of the target load unit does not match its theoretical voltage value.

[0126] S403: Control the voltage dividing component connected to the target load unit to be turned on.

[0127] When the voltage value of the target load unit does not match its theoretical voltage value, it indicates that there is an abnormality in the power supply of the target load unit. In order to ensure the stability of the business on the target load unit, the control unit can control the voltage divider component connected to the target load unit to be turned on. At this time, the upper-level voltage converter of the target load unit is connected to the target load unit through the voltage divider component, thereby realizing short-term power supply to the target load unit.

[0128] S404: When the electric double layer capacitor meets the discharge condition, the electric double layer capacitor is used to supply additional power to the target load unit, and the voltage dividing component connected to the target load unit is switched to a disconnected state.

[0129] In order to ensure that the previous voltage converter will not be overloaded due to power replenishment, when the double-layer capacitor meets the discharge conditions, the double-layer capacitor can be used to supplement the power supply to the target load unit, and the voltage divider connected to the target load unit can be switched to the disconnected state.

[0130] For the description of the features in the embodiment corresponding to FIG4 , reference can be made to the relevant description of the embodiment corresponding to FIG1 , and no further details will be given here.

[0131] It can be seen from the above technical solution that the theoretical voltage value corresponding to each load unit under normal power supply state is read from the memory. It is determined whether the voltage value corresponding to each load unit matches its theoretical voltage value. In the case that the voltage value of the target load unit does not match its theoretical voltage value, it means that there is an abnormality in the power supply of the target load unit. The control unit can control the voltage divider component connected to the target load unit to be turned on, thereby supplying power to the target load unit to ensure the normal operation of the business on the target load unit. When the double-layer capacitor meets the discharge conditions, the double-layer capacitor is used to supplement the power supply to the target load unit, and the voltage divider component connected to the target load unit is switched to the disconnected state, thereby ensuring that the first power supply unit connected to the voltage divider component will not be overloaded due to the supplementary power.

[0132] In response to determining that the voltage value of the target load unit does not match its theoretical voltage value, the control unit receives the capacitance value of the double-layer capacitor, the compensation voltage value of the double-layer capacitor and the load current value of the target load unit transmitted by the monitoring unit; determines the compensation time based on the capacitance value of the double-layer capacitor, the compensation voltage value of the double-layer capacitor and the load current value of the target load unit; in response to determining that the compensation time is greater than the power supply abnormality repair time, repairs the target load unit; in response to determining that the compensation time is less than or equal to the power supply abnormality repair time, backs up the target load unit.

[0133] In practical applications, the capacitance value of the double-layer capacitor can be multiplied by the charging voltage value of the double-layer capacitor, and the product value can be divided by the load current value of the target load unit to obtain the charging time.

[0134] The repair process of the target load unit can include receiving the potential value of each pin of the target load unit transmitted by the monitoring unit; reading the theoretical potential value of each pin of the target load unit under normal power supply state from the memory; and if the target potential value of the target pin is inconsistent with its target theoretical potential value, adjusting the potential value of the target pin to the target theoretical potential value.

[0135] The backup process of the target load unit may include transferring the service data of the target load unit to the corresponding load unit on the controlled device.

[0136] FIG5 is a flow chart of a method for repairing a high-speed link load communication anomaly provided by an embodiment of the present application, the method comprising:

[0137] S501: Receive load communication data of each load unit transmitted by a monitoring unit.

[0138] In addition to power supply anomalies, in actual applications, when power supply is normal, the load unit may have high-speed link load communication anomalies. In the embodiment of the present application, the monitoring unit can obtain the load communication data of each load unit and transmit the load communication data to the control unit.

[0139] S502: When the target load communication data corresponding to the target load unit is abnormal and the target voltage value is normal, the business data of the target load unit is transferred to the corresponding load unit on the controlled device, so that the corresponding load unit on the controlled device processes the business data, sets a mark for the processed new business data and caches it in the memory.

[0140] When the target load communication data corresponding to the target load unit is abnormal and the target voltage value is normal, it means that the target load unit currently has a high-speed link load communication abnormality, but has not stopped working or lost cards or data. In order to avoid the storage power supply coefficient from being down due to the target load unit stopping working or losing cards or data, the business data on the abnormal target load unit can be backed up in advance.

[0141] In actual applications, the business data of the target load unit can be transferred to the corresponding load unit on the control device. After receiving the business data, the corresponding load unit on the control device can process the business data, set a mark for the processed new business data, and cache it in memory.

[0142] S503: Send a reset signal to the target load unit, so that the target load unit restarts based on the reset signal.

[0143] The control unit may send a reset signal to the target load unit, so that the target load unit restarts based on the reset signal.

[0144] S504: Receive the target load communication data of the target load unit transmitted by the monitoring unit.

[0145] The monitoring unit may monitor the target load communication data of the target load unit and transmit the target load communication data to the control unit.

[0146] S505: When the target load communication data is normal, read the marked new service data from the memory.

[0147] After receiving the target load communication data, the control unit can determine whether the target load communication data has returned to normal. If the target load communication data is normal, it means that the target load unit can take over the processing of business data again. At this time, the control unit can read the marked new business data from the memory.

[0148] S506: Send the marked new business data to the target load unit, so that the target load unit processes the marked new business data and stores the processing results in the hard disk.

[0149] The control unit sends the marked new service data to the target load unit. After receiving the marked new service data, the target load unit may process the marked new service data and store the processing result in the hard disk.

[0150] For the description of the features in the embodiment corresponding to FIG5 , reference can be made to the relevant description of the embodiment corresponding to FIG1 , and no further details will be given here.

[0151] It can be seen from the above technical solution that the load communication data of each load unit transmitted by the receiving monitoring unit. When the target load communication data corresponding to the target load unit is abnormal and the target voltage value is normal, the business data of the target load unit is transferred to the corresponding load unit on the control device, so that the corresponding load unit on the control device processes the business data, sets a mark for the processed new business data and caches it in the memory. A reset signal is sent to the target load unit so that the target load unit restarts based on the reset signal. The target load communication data of the target load unit transmitted by the receiving monitoring unit is received. When the target load communication data is normal, the new business data with the mark is read from the memory. The new business data with the mark is sent to the target load unit so that the target load unit processes the new business data with the mark and stores the processing result in the hard disk. The beneficial effect of the present application is that by monitoring the changes in the load communication data, the problem of abnormal high-speed link load communication can be discovered in time. In order to avoid the situation of downtime caused by card loss and data loss, data backup operations can be performed in advance, thereby achieving uninterrupted repair when the high-speed link load communication is abnormal. The control unit proactively sends a reset signal to the load unit experiencing the high-speed link load communication anomaly, restarting the load unit. After the restart, the high-speed link load communication status of the restarted load unit returns to normal. Once the current repair work is determined to be complete, the restored load unit can resume the previous business data processing process. Business data processing is uninterrupted throughout the entire process, and repairs are performed before the load loses its function due to card loss, thus avoiding system downtime.

[0152] The present application provides a hardware structure for a power supply system, which, in conjunction with a load unit power supply anomaly diagnosis and self-repair algorithm, can achieve short-term backup power after an abnormal power outage of the load unit without incurring additional costs. During the short-term backup power process, operations such as power supply repair or data backup of the load unit can be performed, ensuring that the power supply system makes optimal processing in a short period of time, thereby increasing or decreasing the reliability of the storage system. The high-speed link load communication anomaly repair solution provided by the present application repairs the load link anomaly while ensuring the normal operation of the business, so that the anomaly repair process will not cause losses such as data loss and business interruption, thereby improving the reliability of the power supply system operation.

[0153] The power supply system and electronic equipment provided in the embodiments of the present application can be used to repair abnormalities in a unified storage array load unit, and can also be used for equipment with high-speed link loads, and can be applied to business scenarios such as servers and military computers.
