Technical Field

[0001] This application relates to the field of electronic technology, and in particular to a power supply management method and system. Background Technology

[0002] In modern data centers, servers undertake the tasks of storing, processing, and transmitting massive amounts of data, making the performance of their hardware power supply system crucial. However, current server hardware electrical systems suffer from numerous problems: on the one hand, the stability of the power supply is insufficient, and fluctuations in mains power or momentary power outages can easily lead to server hardware damage or data loss. Existing power supply systems mostly use simple uninterruptible power supplies (UPS), but their switching time is long and cannot meet the needs of servers with extremely high requirements for power supply continuity. On the other hand, the internal power supply connections of servers are complex, with numerous cables intertwined, which not only occupies a lot of space and increases the difficulty of heat dissipation, but also easily causes electrical faults due to poor contact, and troubleshooting is difficult.

[0003] Meanwhile, the lack of effective real-time monitoring and intelligent management methods for server operation status makes it impossible to detect potential faults in a timely manner and hinders refined operation and maintenance of the power supply system. For example, in some data centers, server motherboards may burn out due to power supply voltage fluctuations, and the complex cable layout makes troubleshooting electrical faults take several hours or even longer, seriously affecting the normal operation of servers and the work efficiency of the data center.

Detailed Implementation

[0015] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this application.

[0016] It should be noted that, in the description of this application, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. The terms "first," "second," etc., in this application are used to distinguish similar objects and are not used to describe a specific order or sequence.

[0017] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0018] In current server hardware designs, the dual power supply unit (PSU) power supply scheme is a common way to ensure power supply reliability. This is similar to the high-stability power supply module design concept of this application. The dual PSU power supply scheme usually adopts a redundant design, with two PSUs working simultaneously to supply power to the various hardware components in the server. When one PSU fails, the other PSU can seamlessly take over all power supply tasks, preventing the server from shutting down due to power failure.

[0019] Dual power supply unit operating mode: Load sharing mode: Under normal circumstances, the two PSUs each bear a portion of the server's power load, for example, each is responsible for 50% of the power supply task. In this mode, the PSUs operate under low load for a long time, which can effectively reduce heat generation, extend service life, and better cope with sudden high power demand scenarios of the server.

[0020] Primary / backup mode: One PSU acts as the main power supply to power the server, while the other PSU is in hot standby mode. When the main power supply fails, such as in the event of a short circuit, overcurrent, or abnormal voltage, the backup PSU will automatically start and take over the power supply in a very short time (usually within milliseconds) to ensure the continuous operation of the server.

[0021] However, the relevant technology has the following drawbacks: 1. Traditional dual-PSU power supply solutions, even in primary / standby mode, typically have a switching time of tens of milliseconds or even longer. 2. Generally, dual-PSU power supply schemes only provide power supply and redundancy backup functions, and lack effective means to deal with problems such as voltage fluctuations and high-frequency interference in the mains power supply. 3. In a typical dual-PSU power supply scheme, the two PSUs are usually AC power and do not have energy storage function. If there is a long-term power outage, the server will still stop due to the interruption of external power. 4. The dual-PSU power supply scheme has a relatively fixed system architecture and control logic, lacks intelligent monitoring and management functions, and is insufficient in terms of PSU fault warning and intelligent load adjustment. It may also lead to compatibility issues between the two PSUs.

[0022] Embodiments of this application provide a power supply management method, such as... Figure 1 As shown, the method is applied to the first controller in a power supply management system, and the method includes: The first controller acquires the voltage information of the mains power supply at the main power source; If the mains voltage is outside the voltage fluctuation threshold range, the operating status data of the dual power supply module is obtained, and the voltage and / or current fluctuation trend information in the operating status data of the dual power supply module is analyzed. Based on the voltage and / or current fluctuation trend information, it is determined whether the dual power supply module is abnormal. If the dual power supply module is functioning normally, the system acquires the operating environment data of the electrical equipment and analyzes the temperature and humidity data in the operating environment data. Based on the temperature and humidity data, the system determines the comprehensive environmental health index and judges whether the operating environment of the electrical equipment is safe. If the operating environment of the electrical equipment is in a safe state, the main power supply and the backup power supply will be switched.

[0023] It is understood that this application adopts a dual-redundant power switching system design, uses a high-energy-density lithium battery pack as a backup power module design, and implements a modular power supply connection design and the application of flexible flat cables (FFC), as well as the implementation of an intelligent monitoring and management system and the application of artificial intelligence analysis. This application provides a highly stable and intelligent server hardware power supply management system. Through innovative dual power supply design, optimized electrical connection structure and intelligent monitoring and management scheme, it effectively solves the problems of poor stability, battery life and compatibility of existing server hardware power supply systems, and improves the reliability of server operation and maintenance efficiency.

[0024] Embodiments of this application provide a power supply management method, such as... Figure 2As shown, the method is applied to the first controller in a power supply management system. The power supply management system also includes a dual power supply module and electrical equipment. The first controller is connected to both the dual power supply module and the electrical equipment. The dual power supply module is connected to the electrical equipment and includes a main power supply and a backup power supply. The method includes: Step S01: Obtain the voltage information of the mains power at the main power source.

[0025] In step S02, in response to the mains voltage being outside the voltage fluctuation threshold range, the first controller (central control unit) acquires the operating status data of the dual power supply module; it analyzes the voltage and / or current fluctuation trend information in the operating status data of the dual power supply module through a data analyzer, and determines whether the dual power supply module is abnormal based on the voltage and / or current fluctuation trend information.

[0026] Step S021, the power supply management system also includes a voltage sensor and a current sensor. The voltage sensor and current sensor are set in the dual power supply module. The first controller includes a data analyzer, which collects the operating status data of the dual power supply module through the voltage sensor and current sensor. Obtain the main power supply circuit voltage V1(t) and the backup power supply circuit voltage V2(t) at the current time t; Obtain the current I1(t) of the main power supply circuit and the current I2(t) of the backup power supply circuit at the current time t. The voltage difference ΔV(t) between the main power supply and the backup power supply can be calculated using the formula: ΔV(t)=|V1(t)-V2(t)|. When the voltage difference between the main power supply and the backup power supply is less than the first threshold (1% of the rated voltage), the voltage of the dual power supply module is determined to be stable. When the voltage difference between the main power supply and the backup power supply is greater than or equal to the first threshold, it is determined that the dual power supply module has a voltage regulation failure problem. And / or, calculate the current difference ΔI(t) between the main power supply and the backup power supply using the formula: ΔI(t)=|I1(t)-I2(t)|; When the current difference between the main power supply and the backup power supply is less than the second threshold (5-10%), the current of the dual power supply module is determined to be stable. When the current difference between the main power supply and the backup power supply is greater than or equal to the second threshold, it is determined that the dual power supply module has an overload or current failure problem. Calculate the Pearson correlation coefficient between the main power supply circuit voltage V1(t) and the backup power supply circuit voltage V2(t); When the Pearson correlation coefficient is greater than the first preset value (0.95), it is determined that the dual power supply module's main and backup power supplies respond synchronously to load changes. When the Pearson correlation coefficient is less than the second preset value (0.8), it is determined that either power circuit of the dual power supply module is slow to respond or out of control.

[0027] Specifically, the following key parameters are collected: Main power supply circuit voltage V1(t), backup power supply circuit voltage V2(t); Current signals: main power supply circuit current I1(t), backup power supply circuit current I2(t); Calculate the voltage difference: ΔV(t) = |V1(t) - V2(t)|; When ΔV is very small and stable (<±1% of rated voltage), the voltage of the dual power supply module is stable; When ΔV continues to increase, the power supply module fails to regulate voltage, indicating that the power supply module has a voltage regulation failure problem. Calculate the current difference: ΔI(t) = |I1(t) - I2(t)|; Normal: The current of the main power supply and the backup power supply are close (current sharing error <5~10%). Abnormality: If the current of one of the main power supply or backup power supply is significantly higher than normal, it may be due to overload or failure of the other power supply. Calculate the Pearson correlation coefficients r between V1 and V2, and between I1 and I2; When r>0.95, the two power supplies respond synchronously to load changes; When r < 0.8, it indicates that a certain power supply is slow to respond or out of control.

[0028] Step S03: In response to the normal operation of the dual power supply module, the operating environment data of the electrical equipment is obtained, and the temperature and humidity data in the operating environment data of the electrical equipment are analyzed. The comprehensive environmental health index is determined based on the temperature and humidity data, and the operating environment of the electrical equipment is judged to be safe based on the comprehensive environmental health index.

[0029] Step S031, the power supply management system also includes a temperature sensor and a humidity sensor. The temperature sensor and humidity sensor are set on the motherboard or storage device of the electrical equipment. The power supply management system also includes an alarm module. The first controller is connected to the alarm module. In response to the normal operation of the dual power supply module, the temperature and humidity data in the operating environment data of the electrical equipment are analyzed by the data analyzer. Based on the temperature and humidity data, it is determined whether the operating environment of the electrical equipment is safe. The operating environment data of the electrical equipment is collected using temperature and humidity sensors. Obtain the current ambient temperature T and the current ambient relative humidity RH of the electrical equipment; The ambient dew point temperature Td of electrical equipment can be calculated using the formula: Td=T-(100-RH) / 5; Obtain the current temperature of the electrical equipment; Determine whether the current temperature of the electrical equipment is between the third threshold (15-35°C); If yes, then determine that the current ambient temperature of the electrical equipment is safe; if not, then determine whether the current temperature of the electrical equipment is greater than the third preset value (40°C). If the current temperature of the electrical equipment is greater than the third preset value, the first controller sends an alarm command to the alarm module, which then provides a high-temperature alarm to the electrical equipment. If the current temperature of the electrical equipment is less than or equal to the third preset value, the controller determines whether the current temperature of the electrical equipment is close to the dew point temperature. If the current temperature of the electrical equipment is close to the dew point temperature, it is determined that there is a risk of condensation in the operating environment of the electrical equipment. Determine whether the current relative humidity of the electrical equipment is within the fourth threshold (40-70%); If yes, then determine that the current ambient humidity of the electrical equipment is safe; if no, then determine whether the current humidity of the electrical equipment is greater than the fourth preset value (80%). If the current humidity of the electrical equipment is greater than the fourth preset value, it is determined that there is a high humidity risk in the operating environment of the electrical equipment; if the current humidity of the electrical equipment is less than or equal to the fourth preset value, it is determined that there is a low humidity static electricity risk in the operating environment of the electrical equipment. The first controller sends an alarm command to the alarm module, and the alarm module provides a low humidity alarm prompt to the electrical equipment.

[0030] Specifically, when water vapor in the air reaches saturation, it will condense into water droplets (condensation), which can easily cause a short circuit; If Td ≥ Tsurface (equipment surface temperature), condensation may occur. When Td > (T - 3°C), there is a risk of condensation.

[0031] Step S032: Obtain temperature data from the operating environment data of the electrical equipment; The temperature score function f(T) is obtained based on the temperature data in the operating environment data of electrical equipment; Obtain humidity data from the operating environment data of electrical equipment; The humidity score function g(RH) is obtained based on the humidity data in the operating environment data of electrical equipment; Obtain the weight coefficients w1 and w2; The comprehensive environmental health index EHIs is calculated using the formula: EHIs=w1×f(T)+w2×g(RH). When the comprehensive environmental health index is less than the fifth preset value (0.6), the operating environment of the electrical equipment is determined to be unsafe. When the comprehensive environmental health index is between the fifth and sixth preset values, the first controller will issue an early warning to the operating environment of the electrical equipment. When the comprehensive environmental health index is greater than the sixth preset value (0.8), the operating environment of the electrical equipment is determined to be safe.

[0032] Example scoring rules: When the ambient temperature of the electrical equipment is between 15 and 35°C, the temperature score function will receive 1 point. When the ambient temperature of the electrical equipment is 35~40°C, the temperature score function will receive 0.5 points. If the ambient temperature of the electrical equipment is >40°C, the temperature score function will receive 0 points. When the ambient humidity of the electrical equipment is between 40% and 70%, the humidity score function will receive 1 point. When the ambient humidity of the electrical equipment is between 70% and 80%, the humidity score function will receive 0.5 points. If the ambient humidity of the electrical equipment is >80% or <20%, the humidity score function will receive 0 points.

[0033] By rationally designing the temperature and humidity scoring functions and weights, we can achieve: automated scoring, real-time monitoring, hierarchical alarms, and data-driven operation and maintenance decisions. By embedding the comprehensive environmental health index model into the intelligent monitoring and management system, we can realize intelligent health management of the operating environment of electrical equipment.

[0034] Step S04: The power supply management system further includes a remote monitoring terminal, and the first controller is connected to the remote monitoring terminal; in response to an abnormality in the dual power supply module and / or a safety issue in the operating environment of the electrical equipment, the fault processor handles the fault.

[0035] Step S041: The fault processor sends alarm information to the alarm module and then sends the alarm information to the remote monitoring terminal. The electrical equipment is remotely controlled based on the alarm information. The step of remotely controlling the electrical equipment based on the alarm information includes: Determine the fault information based on the alarm information; In response to the fault information indicating an abnormality in the dual power supply module, the power output of the electrical equipment is adjusted, the electrical equipment is restarted, or the power supply circuit of the dual power supply module to the electrical equipment is cut off according to the fault information. If a fault message indicates a safety issue in the operating environment of the electrical equipment, the system will control the rate of temperature rise of the electrical equipment or cut off the power supply circuit of the dual power supply module to the electrical equipment based on the fault message.

[0036] Specifically, voltage sensors, current sensors, temperature sensors, and humidity sensors are installed in key components of the server, such as the power supply lines, motherboard, and storage devices. The data collected by the sensors is transmitted to the central control unit (first controller) through a serial communication interface. The central control unit uses a high-performance microprocessor and runs a fault prediction algorithm based on machine learning. When abnormal data is detected, the central control unit issues an alarm through an audible and visual alarm device and sends the alarm information to a remote monitoring terminal via the network. Administrators can view detailed fault information through the remote monitoring terminal and remotely control the server's power output, device restart, and other operations to achieve remote operation and maintenance management.

[0037] Understandably, when an abnormal status data is detected, the central control unit will immediately issue an alarm and automatically take corresponding measures, such as controlling and adjusting the power output to electrical equipment and cutting off faulty circuits.

[0038] Step S05: The first controller acquires the voltage and current information of the mains power and determines whether the voltage range of the mains power is within the voltage fluctuation threshold range (198V-242V) based on the voltage and current information of the mains power. When the voltage range of the mains power is within the voltage fluctuation threshold range, the main power supply is controlled to supply power to the electrical equipment and to charge the backup power supply. If the mains voltage is outside the voltage fluctuation threshold range and there is an abnormality in the dual power supply module, the switching operation between the main power supply and the backup power supply will be interrupted. If the mains voltage is outside the voltage fluctuation threshold range and the operating environment of the electrical equipment is in an unsafe state, the switching operation between the main power supply and the backup power supply will be interrupted.

[0039] Step S06: In response to the fact that the operating environment of the electrical equipment is in a safe state, the main power supply and the backup power supply are switched.

[0040] Step S061, the dual power supply module includes a second controller, which is connected to the main power supply and the backup power supply respectively, and is also connected to electrical equipment; The first controller sends control commands to the second controller, which then performs the switching operation between the main power supply and the backup power supply based on the phase-locked loop algorithm. The switching operation between the main power supply and the backup power supply is implemented based on the phase-locked loop algorithm, including: The pulse width modulation output of the backup power inverter is adjusted by a phase-locked loop algorithm to ensure that the voltage waveform of the backup power supply is in phase with that of the mains power. The pulse width modulation output of the backup power inverter is adjusted using a phase-locked loop algorithm to ensure that the voltage waveform of the backup power supply is in phase with the mains voltage waveform. This includes: Obtain the phase θin of the mains input Vin and the phase θout of the inverter output Vout of the backup power supply; The phase error is obtained by comparing the phase θin of the mains input Vin with the phase θout of the backup power inverter output Vout. ,in, =θin-θout; Obtain the proportional coefficient Kp, the integral coefficient Ki, and the time differential element dt; Through the formula: ω ctrl =Kp· +Ki·∫ ,dt, calculate the frequency correction signal parameter ω ctrl Among them, the frequency correction signal parameter ω ctrl The correction amount used to adjust the inverter output frequency of the backup power supply; Obtain the mains angular frequency ω grid ; Through the formula: ω ref =ω grid +ω ctrl Calculate the reference angular frequency ω output by the inverter of the backup power supply. ref ; Based on the frequency correction signal parameter ω ctrl Generate a preset phase θ synchronized with the mains power. ref ; Where, θ ref =∫ω ref ,dt; Obtain the target mains voltage amplitude V ref ; According to the preset phase θ of the mains power synchronization ref and target mains voltage amplitude V ref A pulse width modulation (PWM) output signal is generated, which drives the inverter of the backup power supply to output AC power that is synchronized with the amplitude of the mains power, and controls the voltage waveform of the backup power supply to be in phase with the voltage waveform of the mains power.

[0041] Specifically, it continuously monitors the voltage, frequency, and phase of the mains power. Controlling the backup power output: The PWM output of the backup power lithium battery inverter is adjusted through a phase-locked loop (PLL) algorithm to synchronize its AC output with the mains power. Ensure that the voltage waveform output by the inverter of the backup power supply is as consistent as possible with the mains waveform in terms of frequency, phase, and amplitude.

[0042] Step S07, the electrical equipment includes a motherboard, a storage device and a network communication module. In response to supplying power to the electrical equipment through a backup power supply, the load of the electrical equipment is supplied with power according to the load priority of the electrical equipment. Power is supplied to the loads of electrical equipment according to their load priority, including: Set the power supply priority for all loads of the electrical equipment; Power is supplied to the motherboard and storage devices preferentially according to the power supply priority of all loads of the electrical equipment; If the battery capacity of the backup power supply is less than the fifth threshold (30% of the total battery capacity), a shutdown command is sent to the network communication module through the first controller to cut off the power supply to the network communication module.

[0043] Specifically, it distinguishes between the motherboard core, key storage / network, and auxiliary devices; PMIC (Power Management IC) or PDU (Power Distribution Unit) can be used to achieve hierarchical power supply and dynamic power consumption management; When the backup power capacity is insufficient, non-critical loads are shut down or downgraded according to priority to protect core components. This refined power management allows for maximizing the uptime of critical business operations and data security within a limited backup power capacity.

[0044] Understandably, the main power module uses a high-efficiency switching power supply that meets server power supply standards, with an input voltage range of 90V - 264V AC, capable of adapting to mains voltage in different regions; the backup power module uses a high-energy-density lithium battery pack, with battery capacity rationally configured according to the server's power consumption and expected battery life; the intelligent switching controller uses a high-speed digital signal processor (DSP) to determine whether the mains voltage and current are normal by monitoring the mains voltage and current in real time; when the mains voltage is abnormal, the first controller quickly sends a control signal to trigger the switching circuit (second controller) to achieve rapid switching between the main power module and the backup power module.

[0045] The voltage stabilization circuit adopts an adaptive adjustment circuit based on field-effect transistors (MOSFETs), which adjusts the output voltage of the dual power supply module in real time through a feedback control mechanism; the filter circuit adopts a multi-stage LC filter structure to effectively filter out high-frequency interference signals in the mains power.

[0046] Here, this application acquires the operating status data of the dual power supply module and the operating environment data of the electrical equipment; it analyzes the voltage and current fluctuation trends in the operating status data of the dual power supply module using the data analyzer, and determines whether the dual power supply module is abnormal based on the voltage and current fluctuation trends; it analyzes the temperature and humidity data in the operating environment data of the electrical equipment using the data analyzer, and determines whether the operating environment of the electrical equipment is safe based on the temperature and humidity data; in response to the existence of an abnormality in the dual power supply module and / or a safety issue in the operating environment of the electrical equipment, the fault processor handles the fault problem. This application can effectively solve the problems of poor stability, battery life, and compatibility in existing server hardware power supply systems, and improve the reliability and maintenance efficiency of server operation.

[0047] In addition, analyzing the voltage and / or current fluctuation trends in the operating status data of the dual power supply module, and determining whether the dual power supply module is malfunctioning based on the voltage and / or current fluctuation trends, also includes: Obtain the main power supply circuit voltage V1(t) and the backup power supply circuit voltage V2(t) at the current time t; Obtain the current I1(t) of the main power supply circuit and the current I2(t) of the backup power supply circuit at the current time t. Based on the main power circuit voltage V1(t) and the backup power circuit voltage V2(t) at the current time t, it is determined whether the voltages of the main power supply and backup power supply of the dual power supply module are synchronized. If the voltage V1(t) of the main power supply circuit decreases and the voltage V2(t) of the backup power supply circuit increases, then the dual power supply module is considered to be functioning normally.
