Description

Technical Field

[0001] This application relates to the field of power supply technology, and in particular to a power supply fault monitoring method, apparatus, device, and storage medium. Background Technology

[0002] With the increasing demands for massive data transmission and storage brought about by e-commerce, social media, and big data analytics, the construction and development of large-scale data centers has become one solution. The main hardware equipment of a data center consists of servers and power distribution facilities. Power plants transmit standard AC and high-voltage DC power to large data centers. Power supplies within the servers convert high-voltage DC to low-voltage DC to provide the accurate operating voltage for the servers. A typical server is equipped with two to four power supplies to maintain system operation, outputting corresponding wattages, resulting in extremely high overall power consumption. Furthermore, since large data centers can contain hundreds or even thousands of servers, the number of power supplies is also large. If a power supply fails, it can lead to minor issues such as the power supply shutting down, requiring redundant power supplies to maintain voltage; or serious issues such as power supply damage affecting server circuitry safety.

[0003] In traditional implementations, power supplies typically have power output connectors and signal pins to enable power output and data transmission to the server. When a power supply malfunctions during operation, it forcibly shuts down the power output and stops supplying power until the fault is resolved before restoring power. Furthermore, during troubleshooting, communication between the server's baseboard management controller and the power supply is solely through communication, resulting in inaccurate fault location and untimely fault resolution. Summary of the Invention

[0004] Based on this, this application provides a power supply fault monitoring method, device, equipment, and storage medium to solve the defects of inaccurate fault location and untimely fault elimination in the prior art, so as to facilitate power supply maintenance personnel to accurately and timely eliminate power supply faults and restore power supply.

[0041] Figure 5 This is a schematic structural diagram of a computer device in one embodiment. Detailed Implementation

[0042] The present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the scope of the present application.

[0043] For ease of understanding, the system to which this application applies will first be described. The power supply fault monitoring method provided in this application can be applied to, for example... Figure 1 The power supply fault monitoring system architecture shown includes: an external monitoring device 101, a power supply 103, and a baseboard management controller 105; the power supply includes a primary-side DSP and a secondary-side DSP, the primary-side DSP is communicatively connected to the external monitoring device, and the secondary-side DSP is communicatively connected to the baseboard management controller, and both the power supply 103 and the baseboard management controller 105 are located on a server.

[0044] Here, the hardware design of the power supply is entirely digital, with a DSP (Digital Signal Processor) controlling the main functions and peripheral circuitry within the power supply. Generally, the power supply internally requires electrical isolation and performs voltage conversion. Therefore, the power supply consists of a primary-side DSP and a secondary-side DSP. These two DSPs provide voltage isolation, and a universal asynchronous transceiver is used to facilitate data exchange between them.

[0045] Figure 2 A flowchart illustrating a power supply fault monitoring method provided in this application embodiment is provided. This method can be performed by, for example... Figure 1 The system shown is executing. (As indicated) Figure 2 As shown, the method may include the following steps:

[0046] Step 201: External monitoring equipment reads the fault code number of the power supply in real time.

[0047] The power supply unit (PSU) is used to provide the voltage / current conversion required by the server load. It rectifies the external AC mains voltage (110V / 220V) to obtain an unstable DC voltage, then charges it into a stable DC voltage via a capacitor. This stable DC voltage is then switched into an alternating positive and negative voltage by a power switch unit before being stepped down by a transformer. Finally, a filter unit composed of inductors and capacitors forms a standard DC power supply output. However, during this conversion process, the power supply's protection operation may be triggered for known or unknown reasons, causing it to stop converting. This can lead to overvoltage, undervoltage, or overheating within the power supply. Furthermore, the server may require higher voltage during operation, triggering overcurrent protection. Instability in the external AC mains input can also cause the power supply to enter overvoltage or undervoltage protection mode. All of these situations can cause the power supply to stop supplying power and enter standby mode, awaiting troubleshooting by personnel.

[0048] Specifically, since each fault code number is pre-set with corresponding fault information, the power supply will output a fault code number after a fault occurs, and the external monitoring equipment will read the fault code number of the power supply in real time.

[0049] Step 203: The baseboard management controller obtains fault commands from the power supply in real time.

[0050] The baseboard management controller can be a BMC (Baseboard Management Controller).

[0051] Here, since each fault command has a corresponding fault information preset, when the power supply fails, the power supply will report to the BMC using the corresponding fault command. After the BMC obtains the corresponding fault command, it will parse it to obtain the fault information corresponding to the fault command.

[0052] Step 205: The external monitoring device reads the fault code number and the baseboard management controller obtains the fault command. If neither the fault code number nor the fault command is read, proceed to step 207. If the fault code number is read and the fault command is obtained, proceed to step 209.

[0053] Here, the operating status of the power supply is determined based on the fault code number and the reading and acquisition of fault commands.

[0054] Step 207 confirms that the power supply is working properly.

[0055] If the external monitoring device does not read the fault code number and the baseboard management controller does not receive the fault command, it means that the power supply has not failed, and that the power supply is in normal working condition.

[0056] Step 209 determines that the power supply is faulty; and based on the consistency between the fault information corresponding to the fault code number and the fault information corresponding to the fault command, automatically generates corresponding operation information to instruct the staff to operate the power supply.

[0057] Here, if the external monitoring equipment reads the fault code number and the baseboard management controller obtains the fault command, the power supply fault can be determined. However, since each fault code number has a corresponding fault information preset, and each fault command also has a corresponding fault information preset, it is necessary to automatically generate corresponding operation information based on the consistency between the fault information corresponding to the fault code number and the fault information corresponding to the fault command to instruct the staff to operate the power supply, so as to achieve the effect of timely and accurate troubleshooting of the power supply fault and restoration of power supply.

[0058] As can be seen, this embodiment of the application reads the fault code number of the power supply in real time through an external monitoring device; the baseboard management controller obtains the fault command of the power supply in real time; if the external monitoring device does not read the fault code number and the baseboard management controller does not obtain the fault command, the power supply is confirmed to be working normally; if the external monitoring device reads the fault code number and the baseboard management controller obtains the fault command, the power supply is determined to be faulty; and based on the consistency between the fault information corresponding to the fault code number and the fault information corresponding to the fault command, corresponding operation information is automatically generated to instruct the staff to operate the power supply. The above operation adopts dual monitoring of the power supply fault by the external monitoring device and the baseboard management controller, and automatically generates corresponding operation information based on the consistency of the corresponding fault information to instruct the staff to operate the power supply, thereby achieving the effect of facilitating power supply maintenance personnel to analyze and troubleshoot power supply faults in a timely and accurate manner and quickly restore power supply.

[0059] In conjunction with the above embodiments, a detailed description will be given of step 209, which involves "automatically generating corresponding operation information to instruct staff to operate the power supply based on the consistency between the fault information corresponding to the fault code number and the fault information corresponding to the fault command".

[0060] The system determines the consistency between the fault information corresponding to the fault code number and the fault information corresponding to the fault command. If they are consistent, the system automatically generates a corresponding troubleshooting operation instruction to instruct the staff to troubleshoot the power supply based on the corresponding fault information. If they are inconsistent, the system automatically generates a replacement operation instruction to instruct the staff to replace the power supply.

[0061] The fault code numbers include fault codes with known causes and fault codes with unknown causes. Fault codes with known causes include, but are not limited to, 001-input overvoltage, 002-input undervoltage, 003-output overvoltage, 004-output undervoltage, 005-output overcurrent, 006-temperature abnormality, and 007-fan abnormality. Fault codes with unknown causes are 008-replace fault information.

[0062] Fault commands include definitive commands and abnormal commands. Definitive commands include: 7Ch STATUS_INPUT=0x80 command - input overvoltage, 7Ch STATUS_INPUT=0x38 command - input undervoltage, etc., 7Ah STATUS_OUTPUT=0x80 command - output overvoltage, 7Ah STATUS_OUTPUT=0x10 command - output undervoltage, 7Bh STATUS_IOUT=0xA3 command - output overcurrent, 7Dh STATUS_TEMPERATURE=0x40 command - temperature abnormality, and 81h STATUS_FANs_1_2=0xA0 command - fan abnormality, etc. Abnormal commands include: STATUS commands - replace fault information, i.e., commands without any specific information.

[0063] Determine the consistency between the fault information corresponding to the fault code number and the fault information corresponding to the fault command; for example, if the fault code number read by the external monitoring device is 001 and the fault command obtained by the board management controller is 7ChSTATUS_INPUT=0x80, the corresponding fault information is both input overvoltage, which means that the corresponding fault information is consistent. Then, the corresponding fault troubleshooting operation information instruction is automatically generated to instruct the staff to perform fault troubleshooting operations on the power supply according to the corresponding fault information.

[0064] For example, if the external monitoring device reads fault code number 001 and the board management controller receives fault command 7Ah STATUS_OUTPUT=0x80, since fault code number 001 corresponds to input overvoltage and 7Ah STATUS_OUTPUT=0x80 corresponds to output overvoltage, it indicates that the corresponding fault information is inconsistent. Therefore, a replacement operation information instruction is automatically generated to instruct the staff to replace the power supply.

[0065] It should also be noted that if the fault code number read by the external monitoring equipment is an unknown code number, or if the fault command obtained by the baseboard management controller is an abnormal command, there is no need to verify consistency. Instead, a replacement operation instruction will be automatically generated to instruct the staff to replace the power supply. That is, the staff will replace the original power supply and install the backup power supply in the server, restoring the server to normal operation and reducing unnecessary time waste.

[0066] In some embodiments, if the external monitoring device reads a fault code number but the baseboard management controller does not receive a fault command, or if the external monitoring device does not read a fault code number but the baseboard management controller receives a fault command, then a power supply fault is determined; and a replacement operation information instruction is automatically generated to instruct the staff to perform a power supply replacement operation.

[0067] In one feasible approach, if an external monitoring device reads a fault code number, the power supply failure can be determined even if the baseboard management controller does not receive a fault command; and a replacement operation information instruction will be automatically generated to instruct the staff to perform the power supply replacement operation.

[0068] In another possible implementation, if the baseboard management controller receives a fault command, it can determine that the power supply is faulty even if the external monitoring equipment does not read the fault code number; and automatically generate replacement operation information instructions to instruct the staff to replace the power supply.

[0069] In some embodiments, an external monitoring device reads the fault code number of the power supply via a universal serial bus; the baseboard management controller obtains the fault command of the power supply via an I2C bus.

[0070] The Universal Serial Bus (USB) can be used; the USB interface can be a USB interface. The USB interface uses USB 3.0, and the corresponding USB bus is also USB 3.0. USB 3.0 is the third major revision of the Universal Serial Bus, employing a high-speed mode. Its main technical standards include full-duplex support, data packet transmission using transmit list segments, a power supply standard of 900mA, and a transmission speed of 5Gbit / s.

[0071] The reason for using a USB 3.0 design is that it is compatible with both USB 2.0 and USB 1.1, and uses a three-level multi-layer power management technology to provide different power management solutions for different devices. Furthermore, USB 3.0 employs a new packet routing transmission technology. The cable design includes eight internal lines: power and ground lines provide internal power voltage, while the remaining six are data transmission lines. Two differential signal lines are retained for compatibility with USB 2.0, and the four additional data transmission lines transform USB 3.0 into a simplex bus, allowing independent channels for transmission and reception, and enabling simultaneous bidirectional data transmission to meet the 5Gbps bandwidth requirement.

[0072] Here, the power supply is equipped with a USB 3.0 interface, and the primary-side DSP communicates with the USB 3.0 bus. When an external monitoring device is plugged into the power supply's USB 3.0 interface, a communication connection is established between the external monitoring device and the primary-side DSP, serving as a communication bridge between the external monitoring device and the power supply's internal components, so as to more accurately and quickly read the power supply's fault code number.

[0073] The secondary DSP communicates bidirectionally with the BMC via the I2C bus, serving as a communication bridge between the BMC and the power supply. This allows the board management controller to obtain fault commands from the power supply via the I2C bus. Since the I2C bus itself occupies very little space and processes relatively little data, it can meet data transmission requirements while saving space.

[0074] In some embodiments, the method further includes:

[0075] Step 301: The external monitoring equipment reads the operating parameters of the power supply in real time.

[0076] The operating parameters include, but are not limited to, input voltage, input current, input power, output voltage, output current, output power, fan speed, and internal temperature of the power supply.

[0077] Here, the power supply also needs to be monitored during normal server operation. Traditionally, this monitoring is done by the server, and the power supply's operating parameters are only accessible to the server. However, in this application, external monitoring equipment can read the power supply's operating parameters in real time, enabling tracking of server energy consumption and subsequent maintenance.

[0078] Step 303: Based on the working parameters and the preset parameter model, obtain the working variation curve of the power supply.

[0079] Here, after acquiring the operating parameters, the external monitoring equipment substitutes them into the preset parameter model to obtain the operating change curve of the power supply, so that the staff can analyze the operating parameter data of the power supply.

[0080] Step 305: Determine the operating stability of the power supply based on the operating change curve.

[0081] The operating variation curve reflects the stability of the mains voltage and the energy consumption of the server.

[0082] Here, by analyzing the trend of the power supply's operating curve, we can determine the power supply's operational stability, i.e., whether the power supply is currently in a stable state or requires maintenance and inspection. This enables real-time monitoring of the power supply.

[0083] In some embodiments, step 305 above, namely "determining the operating stability of the power supply based on the operating variation curve", is described in detail.

[0084] When the trend of the operating change curve is stable, the power supply is determined to be in a stable state; when the trend of the operating change curve is drastic, the power supply is determined to be in an abnormal state, and a corresponding abnormal information instruction is automatically generated to instruct the staff to check the power supply.

[0085] Here, when the operating curve shows a stable trend, the power supply is considered to be in a stable state, meaning no additional operation is required. When the operating curve shows a sharp change, it indicates an abnormal risk with the power supply, and corresponding abnormal information instructions can be automatically generated to guide staff to check the power supply based on the information. For example, when unstable mains voltage in the computer room, unstable power supply output voltage, abnormal power supply fan speed, or abnormal server energy consumption exceeding the power supply's rated output power are detected, the operating curve will change sharply, potentially causing the power supply to experience voltage spikes (overvoltage or undervoltage) and forcibly shut down its output power. Therefore, real-time analysis and monitoring of the power supply's operating curve are necessary for proper maintenance.

[0086] In some embodiments, external monitoring equipment and basic management controller control the primary and secondary DSPs to perform upgrade operations according to business needs.

[0087] In one feasible approach, the baseboard management controller can control the primary-side DSP and the secondary-side DSP to communicate and complete data transmission to achieve the effect of software upgrade, based on the business needs of the server manufacturer.

[0088] In another feasible approach, external monitoring equipment can control the primary and secondary DSPs to communicate and complete data transmission to achieve software upgrades, thereby extending the lifespan of the power supply.

[0089] It should be understood that, although Figures 2-3 The steps in the flowchart are shown sequentially as indicated by the arrows, but these steps are not necessarily executed in the order indicated by the arrows. Unless explicitly stated in this application, there is no strict order restriction on the execution of these steps, and they can be executed in other orders. Furthermore, Figures 2-3At least some of the steps in the process may include multiple sub-steps or multiple stages. These sub-steps or stages are not necessarily completed at the same time, but can be executed at different times. The execution order of these sub-steps or stages is not necessarily sequential, but can be executed in turn or alternately with other steps or at least some of the sub-steps or stages of other steps.
