[0016] Hereinafter, embodiments of the present application will be described with reference to the accompanying drawings. However, it should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the present application. In the following detailed description, for the sake of explanation, many specific details are set forth to provide a comprehensive understanding of the embodiments of the present application. However, obviously, one or more embodiments can also be implemented without these specific details. In addition, in the following description, descriptions of well-known structures and technologies are omitted to avoid unnecessarily confusing the concepts of the present application.

[0017] The terms used herein are merely for describing specific embodiments and are not intended to limit the present application. The terms "including", "comprising", etc. used herein indicate the presence of the described features, steps, operations, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, or components.

[0018] All terms used herein (including technical and scientific terms) have the meanings commonly understood by those skilled in the art, unless otherwise defined. It should be noted that the terms used herein should be interpreted as having a meaning consistent with the context of this specification and should not be interpreted in an idealized or overly rigid manner.

[0019] In the case of using expressions such as "at least one of A, B, and C, etc.", generally, it should be interpreted according to the meaning commonly understood by those skilled in the art (for example, "a system having at least one of A, B, and C" should include, but is not limited to, a system having only A, only B, only C, having A and B, having A and C, having B and C, and / or having A, B, and C, etc.).

[0020] In the related art, the server is powered directly by a PSU that converts AC to DC. The specific solution is as follows: The mains power is input to the PSU, and the PSU converts the alternating current into direct current suitable for the server to use and supplies power to each component of the server.

[0021] However, when the PSU meets the power supply requirements of diverse and complex server nodes, its flexibility is insufficient. Different server node components, such as CPUs, GPUs, memories, etc., have different requirements for power supply voltage accuracy, current dynamic response capabilities, etc. It is difficult for the PSU to accurately adapt to these differentiated requirements.

[0022] In addition, the existing monitoring of the PSU mostly uses simple hardware sensors, which can only obtain basic electrical parameters such as voltage and current. This method cannot comprehensively reflect the working state of the power supply board. For example, it is difficult to capture key information such as the working temperature of the chips inside the power supply board, the load balance situation, and potential circuit fault hazards, and it is difficult to meet the high requirements of modern data centers for server power supply management. Therefore, the embodiments of the present application provide a power supply detection method for a power distribution board to more efficiently, flexibly, and expansively implement the power supply detection of the power distribution board.

[0023] Figure 1 Fig. shows an application scenario diagram of the power supply detection method for a power distribution board according to an embodiment of the present application.

[0024] As Figure 1 shown, the application scenario 100 according to this embodiment may include power distribution board 1 to power distribution board n and server node 120. Among them, taking power distribution board 1 as an example, power distribution board 1 includes a voltage regulating device 111, a programmable logic device 112, and a monitoring device 113; the server node 120 includes a baseboard management controller 121; n is an integer greater than or equal to 1.

[0025] The baseboard management controller 121 in the server node 120 can send a power status query instruction to the programmable logic device 112 arranged on the power distribution board 1, send a reading instruction to the voltage regulating device 111 arranged on the power distribution board 1, and send a health status query instruction to the monitoring device 113 arranged on the power distribution board 1. Thus, the baseboard management controller 121 can perform power supply detection on the power distribution board 1 according to the power input status received from the programmable logic device 112, the electrical parameters received from the voltage regulating device 111, and the power distribution board health status parameters received from the monitoring device 113, and obtain a detection result.

[0026] Among them, the electrical parameters include the electrical parameters provided by the power distribution board 1 to the server node 120.

[0027] According to an embodiment of the present application, one server node can correspond to one or more power distribution boards.

[0028] It should be understood that Figure 1 the number of server nodes and power distribution boards in

[0029] is merely illustrative. According to the implementation requirements, there can be any number of server nodes and power distribution boards. Figure 1 The following will be based on Figures 2 to 3 the described scenario to describe in detail the power supply detection method for the power distribution board according to the embodiments of the present application through

[0030] Figure 2 FIG. schematically shows a flowchart of the power supply detection method for the power distribution board according to the embodiments of the present application.

[0031] The BMC (Baseboard Management Controller) in the server node executes the power supply detection method for the power distribution board.

[0032] As Figure 2 shown, the method 200 includes operations S210 to S240.

[0033] In operation S210, a power status query instruction is sent to the programmable logic device disposed on the power distribution board.

[0034] According to an embodiment of the present application, the programmable logic device disposed on the power distribution board (PDB, Power Distribution Board) can be a CPLD (Complex Programmable Logic Device).

[0035] In operation S220, a read instruction is sent to the voltage regulating device disposed on the power distribution board.

[0036] According to an embodiment of the present application, the voltage regulator disposed on the power distribution board can be a VR (Voltage Regulator) for regulating voltage.

[0037] In operation S230, a health status query instruction is sent to the monitoring device disposed on the power distribution board.

[0038] According to an embodiment of the present application, the monitoring device disposed on the power distribution board can be a custom-made Monitor. That is, the parameters on the power distribution board to be collected by the monitoring device can be customized.

[0039] Since the power distribution board converts direct current into the direct current required by the server nodes, it is necessary to perform a power supply detection on the power distribution board to ensure the stable operation of the server nodes.

[0040] During the power supply detection of the power distribution board, the BMC can send a power status query instruction to the programmable logic device arranged on the power distribution board, a read instruction to the voltage regulation device arranged on the power distribution board, and a health status query instruction to the monitoring device arranged on the power distribution board.

[0041] Among them, the order and time of the BMC sending the power status query instruction, the read instruction, and the health status query instruction can be arbitrary, and the BMC can regularly send the power status query instruction, the read instruction, and the health status query instruction.

[0042] In operation S240, in response to receiving the power input status from the programmable logic device, the electrical parameters from the voltage regulation device, and the health status parameters of the power distribution board from the monitoring device, according to the power input status, the electrical parameters, and the health status parameters, perform a power supply detection on the power distribution board to obtain a detection result.

[0043] Among them, the electrical parameters include the electrical parameters provided by the power distribution board to the server nodes.

[0044] After the BMC sends a power status query instruction to the programmable logic device, the programmable logic device, in response to the power status query instruction, obtains the power input status of the power distribution board and sends the obtained power input status to the BMC.

[0045] The voltage regulation device obtains the electrical parameters output by the power distribution board to the server nodes in real time. After the BMC sends a read instruction to the voltage regulation device, the voltage regulation device will send the obtained electrical parameters to the BMC.

[0046] The monitoring device monitors and collects the health status parameters of the power distribution board in real time. After the BMC sends a health status query instruction to the monitoring device, the monitoring device will send the collected health status parameters to the BMC.

[0047] According to an embodiment of the present application, after receiving the power input status, the electrical parameters, and the health status parameters, the obtained power input status, the electrical parameters, and the health status parameters can be stored in a database for subsequent query and analysis. Thus, a power supply detection can be performed on the power distribution board according to the power input status, the electrical parameters, and the health status parameters to obtain a detection result for the power distribution board. At the same time,

[0048] In one embodiment, the BMC and the programmable logic device can interact through I2C (Inter-Integrated Circuit); the BMC and the voltage regulation device can interact through the PM Bus (Power Management Bus, a communication protocol for power management); the BMC and the monitoring device can interact through I2C.

[0049] According to an embodiment of the present application, a programmable logic device, a voltage regulation device, and a monitoring device are arranged on the power distribution board. The BMC on the server node can interact with the programmable logic device, the voltage regulation device, and the monitoring device on the power distribution board, so as to obtain information on the power input state, electrical parameters, health status, etc. of the power distribution board, perform power supply detection on the power distribution board, and achieve comprehensive monitoring of the power supply of the power distribution board. Moreover, since the power distribution board is detected from aspects such as the power input state, electrical parameters, and health status, potential fault risks in the power distribution board can be discovered in advance, and maintenance can be carried out in a timely manner, further improving the reliability of the power supply of the power distribution board.

[0050] Moreover, since the power distribution board supplies power to each component in the server node respectively, when a certain power distribution board fails, it will not affect the normal operation of other server nodes, reducing the risk of the entire server shutting down due to the power failure of the power distribution board.

[0051] According to an embodiment of the present application, power supply detection is performed on the power distribution board according to the power input state, electrical parameters, and health status parameters, and the detection result is obtained, including: when the verification of the power input state, electrical parameters, and health status parameters passes, the power status of the power distribution board is detected according to the power input state, and the first detection sub-result is obtained; the power supply status of the power distribution board is detected according to the electrical parameters and the preset electrical index values, and the second detection sub-result is obtained; the health status of the power distribution board is detected according to the health status parameters of each component of the power distribution board and the preset health index values, and the third detection sub-result is obtained.

[0052] Among them, the detection result includes the first detection sub-result, the second detection sub-result, and the third detection sub-result.

[0053] According to an embodiment of the present application, on the basis that the BMC obtains the power input state, electrical parameters, and health status parameters from the programmable logic device, voltage regulation device, and monitoring device on the power distribution board, the obtained data will be verified first to ensure the accuracy and integrity of the data.

[0054] According to an embodiment of the present application, the power input status may include information such as whether there is an input power supply on the power distribution board and whether the input power supply is normal.

[0055] Based on the power input status, the power status of the power distribution board can be detected to obtain a first detection sub-result. This first detection sub-result can be used to characterize whether the power status of the power distribution board is normal.

[0056] According to an embodiment of the present application, the electrical parameters may include the voltage and current output by the power distribution board to the server node, and the power calculated based on the voltage and current.

[0057] Based on the electrical parameters and preset electrical index values, the power supply status of the power distribution board can be detected to obtain a second detection sub-result. This second detection sub-result can be used to characterize whether the power supply status of the power distribution board is normal.

[0058] Among them, the preset electrical index values can represent the electrical index values for the normal operation of the preset server node.

[0059] In one embodiment, the electrical parameters can be compared with the preset electrical index values to obtain a comparison result. Based on the comparison result, the second detection sub-result can be obtained.

[0060] According to an embodiment of the present application, the health status parameters may include the health status parameters of each component of the power distribution board. The health status parameters may include parameters such as the temperature and operating frequency of each component of the power distribution board, and these parameters can reflect the health status of the power distribution board.

[0061] Based on the health status parameters of each component of the power distribution board and the preset health index values, the health status of the power distribution board can be detected to obtain a third detection sub-result. This third detection sub-result can be used to characterize whether the health status of the power distribution board is normal.

[0062] Among them, the preset health index values can represent the health index values for the normal operation of the preset power distribution board.

[0063] In one embodiment, the health status parameters can be compared with the preset health index values to obtain a comparison result. Based on the comparison result, the third detection sub-result can be obtained.

[0064] According to an embodiment of the present application, based on the power input status, the power status of the power distribution board can be detected; based on the electrical parameters, the power supply status of the power distribution board can be detected; and based on the health status parameters, the health status of the power distribution board can be detected, realizing multi-faceted detection of the power distribution board. Such that based on the obtained first detection sub-result, second detection sub-result, and third detection sub-result, it is possible to more accurately determine whether there is an abnormality in the power distribution board and respond to the abnormal situation in a timely manner.

[0065] According to an embodiment of the present application, the power supply detection method for the power distribution board further includes: sending an alarm message when at least one of the first detection sub-result, the second detection sub-result, and the third detection sub-result indicates a failed detection.

[0066] According to an embodiment of the present application, when the first detection sub-result characterizes that the input power supply of the power distribution board is abnormal or there is no input power supply, it can indicate that the detection of the power supply status of the power distribution board fails.

[0067] According to an embodiment of the present application, when the second detection sub-result characterizes that the electrical parameters are abnormal compared with the preset electrical index values, it can indicate that the detection of the power supply status of the power distribution board fails.

[0068] For example, the abnormal electrical parameters can characterize a situation where a certain parameter should not be too high and this parameter is greater than the preset electrical index value; for a situation where a certain parameter should not be too low, this parameter is less than the preset electrical index value.

[0069] In another embodiment, for a certain parameter in the electrical parameters, the corresponding preset electrical index value can include two values to form a preset range. If this parameter exceeds the preset range, then this parameter is abnormal.

[0070] According to an embodiment of the present application, when the third detection sub-result characterizes that the health status parameter is abnormal compared with the preset health index value, it can indicate that the detection of the health status of the power distribution board fails.

[0071] For example, the abnormal health status parameter can characterize a situation where a certain parameter should not be too high and this parameter is greater than the preset health index value; for a situation where a certain parameter should not be too low, this parameter is less than the preset health index value.

[0072] According to an embodiment of the present application, when at least one of the first detection sub-result, the second detection sub-result, and the third detection sub-result indicates a failed detection, it indicates that there is an abnormal situation with the power distribution board, and the BMC can send an alarm message.

[0073] In one embodiment, the alarm message can be sent in various ways, such as by text message, pop-up window, email, etc.

[0074] According to an embodiment of the present application, when at least one of the first detection sub-result, the second detection sub-result, and the third detection sub-result indicates a failed detection, an alarm message is sent to promptly prompt that there may be a potential fault risk with the power distribution board, so that the administrator can promptly check and maintain the power distribution board.

[0075] According to an embodiment of the present application, the power supply detection method for the power distribution board further includes: in response to a power switch instruction, sending a power control signal to a programmable logic device, so that the programmable logic device controls a power switch device on the power distribution board to perform a power-on or power-off operation in response to the power control signal; in response to receiving an execution result from the programmable logic device, sending the execution result to a management platform to confirm the execution status of the power-on or power-off operation.

[0076] According to an embodiment of the present application, when it is necessary to operate the power supply of a server node, such as turning on the power supply to the server node or turning off the power supply to the server. A power switch instruction can be sent from the management platform to the BMC, and after receiving the power switch instruction, the BMC sends a power control signal to a programmable logic device.

[0077] The programmable logic device controls a power switch device on the power distribution board to perform a power-on or power-off operation in response to the power control signal, so as to turn on or off the power supply of the server node.

[0078] The programmable logic device sends the execution result to the BMC, and the BMC then sends the execution result to the management platform, so as to confirm the execution status of the power-on or power-off operation of the power switch device on the power distribution board on the management platform.

[0079] Among them, the execution status can indicate that the power switch device has turned on the power supply or turned off the power supply.

[0080] According to an embodiment of the present application, in the case of operating the power supply of a server node, a power control signal is sent to a programmable logic device to control a power switch device on the power distribution board to turn on or off through the programmable logic device, so as to control the power supply of the server node, that is, the power supply control of the server node, so that the power distribution board can be flexibly managed according to the actual situation of the server node to meet the power supply requirements of the server node.

[0081] According to an embodiment of the present application, the power supply detection method for the power distribution board further includes: obtaining a power supply policy corresponding to the load status of the server node; sending a voltage output value and a current output value to a voltage regulating device, so that the voltage regulating device adjusts the voltage and current output by the power distribution board to the server node according to the voltage output value and the current output value; sending the working states of each component to a programmable logic device, so that the programmable logic device adjusts the working states of each component on the power distribution board according to the working states of each component to implement the power supply policy.

[0082] Among them, the power supply policy can include the voltage output value, the current output value of the power distribution board, and the working states of each component.

[0083] According to an embodiment of the present application, a power supply policy for server nodes is set in the management platform. For example, when the server node is under low load, it is necessary to reduce the power output to save energy; when the server node is under high load, it is necessary to ensure a stable power supply.

[0084] Thus, the BMC can obtain the power supply policy for the load status from the management platform according to the load status of the server node.

[0085] The BMC can send the voltage output value and current output value in the power supply policy to the voltage regulator, and the voltage regulator adjusts the voltage and current output from the power distribution board to the server node according to the voltage output value and current output value.

[0086] The BMC can send the operating states of each component in the power supply policy to the programmable logic device, and the programmable logic device adjusts the operating states of each component on the power distribution board according to the operating states of each component.

[0087] Thus, the power supply policy is realized by adjusting the voltage and current output from the power distribution board to the server node and the operating states of each component on the unit distribution board.

[0088] According to an embodiment of the present application, the load status of the server node is monitored in real time, so as to obtain the power supply policy for the load status of the server node, and send corresponding parameters to the voltage regulating device and the programmable logic device respectively, so that the voltage regulating device and the programmable logic device adjust the power distribution board based on the parameters in the power supply policy to realize the power supply policy. Thus, the power distribution board is adjusted based on the power supply policy, realizing flexible management of the power distribution board, which is beneficial to improving energy utilization efficiency and meeting the high requirements for power supply management of the power distribution board.

[0089] According to an embodiment of the present application, the above power supply detection method for the power distribution board further includes: obtaining the electrical parameter information of each component in the server node; determining the abnormal component in the server node according to the electrical parameter information of the component.

[0090] According to an embodiment of the present application, the BMC will monitor the electrical parameter information of each component in the server node in real time to determine whether there is an abnormality in the server node based on the electrical parameter information of each component. Among them, the abnormal component can represent abnormal power consumption, abnormal power supply, excessive power consumption, etc.

[0091] According to an embodiment of the present application, based on the refined monitoring and management of each component of the server node by the BMC, electrical parameter information of each component in the server node can be obtained, such as voltage, current, power consumption, etc. According to the electrical parameter information, it is possible to determine whether there are abnormal components in the server node. And in the case of component abnormalities, the abnormal components in the server node can be quickly and timely determined, so as to take measures to solve the problem in time and ensure the stable operation of the server node.

[0092] According to an embodiment of the present application, the above-mentioned power supply detection method for the power distribution board further includes: when the power consumption information of the abnormal component is greater than the preset power consumption value, sending a power consumption limit instruction to the voltage regulating device, so that the voltage regulator adjusts the power consumption output by the power distribution board to the abnormal component according to the power consumption limit instruction until the power consumption of the abnormal component is less than or equal to the preset power consumption value.

[0093] Among them, the electrical parameter information includes power consumption information.

[0094] According to an embodiment of the present application, when there is an abnormality in the power consumption of the abnormal component, that is, the power consumption information of the abnormal component is greater than the preset power consumption value. Among them, the preset power consumption value is the power consumption value of the preset normal operation of the component.

[0095] According to an embodiment of the present application, sending a power consumption limit instruction to the voltage regulator, the voltage regulator can adjust the power consumption output by the power distribution board to the component according to the power consumption limit instruction until the power consumption of the component is less than or equal to the preset power consumption value.

[0096] According to an embodiment of the present application, when the power consumption of the abnormal component is greater than the preset power consumption value, a power consumption limit instruction can be sent to the voltage regulating device, so that the voltage regulator adjusts the power consumption output by the power distribution board to the abnormal component, so as to limit the power consumption of the component to the preset power consumption value, realizing the power consumption control of the components in the server node through the power distribution board, and meeting the high requirements for the power supply management of the power distribution board.

[0097] Based on the above content, it can be seen that the power supply detection method for the power distribution board of the present application improves the real-time performance of the power supply monitoring of the power distribution board, ensures that the BMC can timely obtain the information of the power distribution board supplying power to the server node, and quickly responds to the abnormal situation of the power distribution board, ensuring the stable operation of the server. At the same time, it also enriches the functions of power supply monitoring, realizes more accurate detection of voltage, current, power, etc. of the power distribution board, and can also realize more flexible power switch control, power strategy setting and power consumption limit of the server node based on the power distribution board, meeting the diverse needs of server power supply in different application scenarios.

[0098] Figure 3Schematically shows a schematic diagram of a power supply system for a whole cabinet server according to an embodiment of the present application.

[0099] As Figure 3 shown, the whole cabinet server 310 can provide direct current power for the power distribution board.

[0100] Thus, taking the whole cabinet server providing direct current power for the power distribution board as an example, the power supply detection method for the power distribution board of the present application enhances the scalability of power supply detection, adapts to the increasing demand for the scale of the whole cabinet server, and reduces the wiring complexity.

[0101] The power supply detection method for the power distribution board of the present application is not only applicable to the power supply system of the whole cabinet server, but also applicable to other fields that require precise monitoring and management of power, such as industrial control equipment, communication base stations, etc.

[0102] Taking a communication base station as an example, in a communication base station, it is necessary to provide stable power for a large number of communication devices and monitor the power in real time to ensure the normal operation of the communication devices.

[0103] For example, the power input of a communication base station may be alternating current, which needs to be converted into direct current first, and then the power is distributed and converted through the power distribution board. Secondly, the monitoring device in the communication base station can be a BMC, which communicates with the monitoring devices on the power distribution board through the PM Bus protocol to realize the monitoring of parameters such as the power state, voltage, current, and power in the power distribution board. In terms of power control, the power strategy can be dynamically adjusted according to the change of the traffic volume of the communication base station. For example, at night when the traffic volume is low, the power supply power of some devices can be reduced to achieve the purpose of energy saving.

[0104] Thus, based on the power supply detection method for the power distribution board of the present application, it can provide efficient and reliable power monitoring and management for the communication base station, and improve the operation stability and energy utilization efficiency of the communication base station.

[0105] Based on the above power supply detection method for the power distribution board, the present application also provides a power supply detection device for the power distribution board. The following will be combined with Figure 4 to describe this device in detail.

[0106] Figure 4 Schematically shows a structural block diagram of a power supply detection device for a power distribution board according to an embodiment of the present application.

[0107] As Figure 4 shown, the power supply detection device 400 for the power distribution board in this embodiment includes a first sending module 410, a second sending module 420, a third sending module 430, and a detection module 440.

[0108] The first sending module 410 is configured to send a power status query instruction to the programmable logic device disposed on the power distribution board. In one embodiment, the first sending module 410 may be configured to perform the operation S210 described above, which will not be elaborated herein.
