[0002] With the rapid development of information technology, data centers play a crucial role in today's digital age. The scale of data centers continues to expand, and the data volume and computing tasks they carry are becoming increasingly heavy. Against this background, the requirements for servers are constantly increasing.

[0024] The power supply system of the whole cabinet server mainly consists of multiple power supply modules, and these power supply modules are connected to the server unit through a bus. The power supply module includes a main power supply module, a backup power supply module, a DPM power distribution module, and an energy efficiency monitoring module. In addition, the system also includes a redundancy design module and a thermal simulation software-assisted heat dissipation design, etc.

[0025] Embodiment 1,

[0026] Reference Figure 1 , the present invention provides an embodiment, a power supply system for a whole cabinet server, including multiple power supply modules, and the power supply modules are connected to the server unit through a bus. Among them, the power supply module includes: a main power supply module for providing the DC power required by the system, and the main power supply module is controlled through a power management module to dynamically adjust the output voltage and current to meet the requirements of different loads; a backup power supply module, which automatically connects to work when the main power supply module fails to ensure the continuous power supply of the system; a DPM power distribution module for distributing power from the main power supply unit or the backup power supply unit to several server units as needed, and each server unit receives power supply of different voltage levels according to needs; an energy efficiency monitoring module for real-time monitoring of the energy efficiency status of the power supply system and feedbacking the monitoring information to the central processor through a communication interface.

[0027] The main power supply module is used to provide the DC power required by the system. It is controlled through a power management module and can dynamically adjust the output voltage and current to adapt to the requirements of different loads. For example, when the server load is light, the output voltage and current are reduced to improve energy utilization efficiency; when the server load increases, the output voltage and current are correspondingly increased to ensure the stable operation of the server.

[0028] The backup power supply module automatically connects and operates when the main power supply module fails, ensuring continuous power supply to the system. The backup power supply module adopts a hot-swappable design, facilitating replacement and maintenance without affecting the system operation. For example, when the main power supply module fails, the system can quickly switch to the backup power supply module to ensure that the server will not interrupt services due to power failure. At the same time, the system will issue an alarm to notify the operators for timely repair and replacement.

[0029] The DPM power distribution module is used to distribute power from the main power supply unit or the backup power supply unit to several server units as needed. Each server unit receives power supply at different voltage levels according to requirements. The power management unit collects server load and energy efficiency data in real time and presets the output mode of the power supply. It preprocesses the server load energy efficiency data to provide accurate data support for subsequent power distribution. For example, the load condition and energy consumption of the server are monitored in real time through sensors, and these data are transmitted to the power management unit for analysis and processing. The cloud monitoring subunit collects the historical energy efficiency data and real-time working status data of several server units through big data analysis, and dynamically adjusts the cabinet power supply configuration in combination with machine learning algorithms. For example, the cloud server analyzes the energy efficiency data of a large number of servers to find the laws and trends of energy efficiency optimization, and then adjusts the cabinet power supply configuration according to these laws and trends to improve energy utilization efficiency. The adaptive power interface subunit automatically switches the power output mode according to the real-time load demand to adapt to different usage scenarios of servers. For example, when the load demand of the server changes, the adaptive power interface subunit can automatically adjust the power output mode to meet the different needs of the server.

[0030] The DPM power distribution module includes a power management unit that collects server load and energy efficiency data in real time, presets the output mode of the power supply, and preprocesses the server load energy efficiency data; a DPM power distribution unit that realizes dynamic load distribution for several server units according to the embedded DPM algorithm, and outputs the power distribution analysis result according to the power consumption demand and real-time load change of the server unit; a multi-level dynamic energy efficiency regulation unit that receives the power distribution analysis result data in the DPM power distribution unit and dynamically regulates the power input of each server unit, including automatically switching the power mode and performing energy-saving optimization processing on low-load units; a fault detection and self-repair unit that is used to automatically detect and diagnose the fault cause when an abnormality occurs in the power supply unit or the server unit, isolate the fault area through the self-repair mechanism, and automatically switch to the backup power supply or the repair path.

[0031] The data collection subunit receives the load energy efficiency data of the server unit in real time. By deploying a number of sensors and data acquisition devices, the load conditions and energy consumption of the server unit are collected in real time, and these data are transmitted to the data collection subunit for analysis and processing.

[0032] The DPM algorithm control subunit inputs the collected data into it, and conducts data analysis and processing on the power consumption requirements and load status of the current system according to the embedded DPM algorithm. For example, using the DPM algorithm to analyze the load conditions and energy consumption of the server, and finding the optimal power allocation strategy to improve energy utilization efficiency.

[0033] The steps in the DPM algorithm control subunit, the core idea is to model through the diffusion process and the inverse diffusion process. First, a power allocation model is constructed, and the application formula is

[0034] The goal of the DPM algorithm is usually to minimize energy consumption, under the premise of meeting the task performance requirements. For example, for a system processing tasks, our goal may be to minimize the total power while ensuring that the performance requirements of each task are not violated. It can be achieved through the following optimization goals, and the formula is

[0035]

[0036] The power allocation calculation subunit decides the power supply allocation strategy result according to the load demand, power consumption prediction and system configuration. For example, according to factors such as the load demand, power consumption prediction and system configuration of the server, calculate the optimal power supply allocation strategy, and then allocate the power supply to each server unit.

[0037] The prediction and optimization subunit presets a data prediction model, predicts the power consumption requirements and load change trends according to historical data, compares with the data prediction model, and adjusts the power supply allocation strategy result in real time. For example, using historical data to establish a data prediction model, predicting the power consumption requirements and load change trends of the server, and then adjusting the power supply allocation strategy according to the prediction results to improve energy utilization efficiency.

[0038] The multi-level dynamic energy efficiency regulation unit receives the power supply allocation analysis result data in the DPM power allocation unit, dynamically regulates the power supply input of each server unit, including automatically switching the power supply mode, and at the same time conducts energy-saving optimization processing on low-load units. The multi-level voltage conversion subunit regulates the input voltage of the server unit. For example, according to the different requirements of the server unit, adjust the input voltage to an appropriate level to improve energy utilization efficiency.

[0039] The power mode switching sub-unit automatically adjusts the power mode of the server unit, receives the power distribution analysis data provided by the DPM, analyzes the load conditions of each server unit, determines whether it can switch to the energy-saving mode, dynamically switches the power mode, and automatically adjusts the power supply according to the real-time load requirements of the server unit. For example, when the load of the server unit is light, it automatically switches to the energy-saving mode to reduce power consumption; when the load of the server unit increases, it automatically switches to the normal mode to increase the power supply.

[0040] The load detection and power regulation sub-unit detects the real-time load of the server and dynamically adjusts the power input to adapt to the changes, and performs real-time power regulation according to the load conditions. For example, it monitors the load conditions of the server in real time through sensors, and adjusts the power input according to the load changes to ensure the stable operation of the server.

[0041] The low-load optimization sub-unit receives the status information of the low-load unit and decides whether to enter the low-power mode for the low-load unit according to the load conditions. For example, when the load of the server unit is low, the low-load optimization sub-unit switches it to the low-power mode to reduce power consumption.

[0042] The temperature and heat dissipation control sub-unit monitors the temperature status of the server unit, adjusts the power supply according to the temperature changes, reduces the power input in high-temperature situations to reduce the heat dissipation pressure, and provides feedback data on temperature and power regulation to the DPM power distribution unit to optimize the power distribution strategy. For example, it monitors the temperature status of the server unit in real time through temperature sensors, and when the temperature is too high, it reduces the power input to reduce the heat dissipation pressure to ensure the stable operation of the server.

[0043] The fault detection and self-repair unit is used to automatically detect and diagnose the cause of the fault when an abnormality occurs in the power unit or the server unit, isolate the faulty area through the self-repair mechanism, and automatically switch to the standby power supply or the repair path. For example, when a fault occurs in the power unit or the server unit, the fault detection and self-repair unit can quickly detect the cause of the fault and isolate the faulty area to prevent the spread of the fault. At the same time, it automatically switches to the standby power supply or the repair path to ensure the continuous power supply and stable operation of the system.

[0044] The energy efficiency monitoring module is used to monitor the energy efficiency status of the power supply system in real time and feedback the monitoring information to the central processor through the communication interface. For example, it monitors the energy efficiency status of the power supply system in real time through sensors and data acquisition devices, including parameters such as input power, output power, and energy consumption. It feeds back this monitoring information to the central processor through the communication interface for data analysis and processing to find the space and direction for energy efficiency optimization.

[0045] Redundant design module, which is used to monitor the power distribution unit and input lines in real time. When the main power line fails, it switches to the backup power module and issues an alarm to notify the operator. For example, through redundant design, it is ensured that when the main power line fails, the system can quickly switch to the backup power module to guarantee the continuous power supply of the system. At the same time, an alarm is issued to notify the operator for timely repair and replacement.

[0046] Use thermal simulation software to simulate and analyze the heat dissipation of the power supply system, and predict the temperature distribution and heat flow path under different working conditions. By adjusting the shape, size, layout of the heat sink, coolant parameter data, etc., ensure that the power module operates within the normal working temperature range. For example, use thermal simulation software to simulate and analyze the heat dissipation of the power supply system, find out the heat dissipation bottleneck and optimization direction. Then, by adjusting the shape, size, layout of the heat sink, coolant parameter data, etc., improve the heat dissipation efficiency and ensure that the power module operates within the normal working temperature range.

[0047] Several power supply modules in the system have communication interfaces for data interaction with the energy efficiency monitoring module, facilitating the operator to remotely monitor and maintain the power supply system. For example, through the communication interface, the operator can remotely monitor the operating status of the power supply system, including parameters such as input power, output power, energy consumption, temperature, etc. At the same time, the operation of the power supply system can also be remotely controlled, such as adjusting the output voltage and current, switching the power mode, etc.

[0048] This integrated cabinet server power supply system is applicable to various server application scenarios, such as data centers, enterprise server rooms, cloud computing centers, etc. In a data center, there are a large number of servers with frequent load changes, and very high requirements are placed on the reliability and energy efficiency of the power supply system.

For example, through the DPM power distribution module, the power distribution can be dynamically adjusted according to the load changes of the servers, improving the energy utilization efficiency; through the redundant design module, it is ensured that when the main power line fails, the system can quickly switch to the backup power module to guarantee the continuous operation of the data center. Enterprise server rooms usually need to provide stable power supply for various business systems of the enterprise. This integrated cabinet server power supply system can provide an efficient and reliable power supply solution for enterprise server rooms to ensure the stable operation of enterprise business systems. For example, through the energy efficiency monitoring module, enterprises can monitor the energy efficiency status of the power supply system in real time, find out the space and direction for energy efficiency optimization, and reduce energy costs; through the thermal simulation software-assisted heat dissipation design, it is ensured that the power module operates within the normal working temperature range, improving the reliability and stability of the system.
