Among them, the N power supply modules are named as power supply module 1, power supply module 2, power supply module 4...power supply module N according to their response time from shortest to longest.
具体来说，电源模块用于：为根据主从调整指令控制自身的供电模式服务器供电，并根据供电状态输出供电指示信号；还有用于采集供电指示叠加信号，用于确定工作的电源模块数量，并发送至服务器电源模块。每个电源模块上均设有电源备援指示信号端口，电源备援指示信号端口互相并联，用于发送和侦测电源备援指示信号。Specifically, the power supply module is used to: supply power to the server in the power supply mode that controls itself according to the master-slave adjustment command, and output a power supply indication signal according to the power supply status; it is also used to collect power supply indication superposition signals to determine the number of working power supply modules, And send to the server power module.

具体的，如图2所示，单片机包括：控制单元、指示单元、第一检测单元、第二检测单元和通讯单元，所述控制单元分别与指示单元、第一检测单元、第二检测单元和通讯单元连接；所述指示单元，用于根据电源模块的供电状态生成供电指示信号并发送至模拟加法器；所述第一检测单元，用于采集模拟加法器生成的供电指示叠加信号；所述第二检测单元，用于侦测电源备援指示信号；所述通讯单元，用于与服务器CPU进行信号传输。Specifically, as shown in Figure 2, the single-chip microcomputer includes: a control unit, an indication unit, a first detection unit, a second detection unit and a communication unit, and the control unit is connected with the indication unit, the first detection unit, the second detection unit and the communication unit respectively.

Then the server CPU communicates through I2C to instruct the power module to enter the intelligent control mode. The power module can adjust the power supply to operate in a state with better efficiency according to the detected information.
实施例二：Embodiment two:
基于实施例一，如图3所示，本发明还公开了一种服务器电源智能调配方法，具体包括如下步骤：Based on Embodiment 1, as shown in FIG. 3 , the present invention also discloses a server power supply intelligent allocation method, which specifically includes the following steps:
S1：采集供电指示叠加信号，根据供电指示叠加信号和供电指示信号确定运行的电源模块数量N。S1: collect the superimposed signal of the power supply indication, and determine the number N of running power modules according to the superimposed signal of the power supply indication and the power supply indication signal.
具体来说，若供电指示叠加信号的值为供电指示信号的N倍，则确定当前有N个电源模块运行。Specifically, if the value of the power supply indication superimposed signal is N times that of the power supply indication signal, it is determined that there are currently N power supply modules running.
其中，需要特别说明的是，N个电源模块根据其反应时间由短至长依次命名为电源模块1至电源模块N。即反应时间最短的电源模块命名为电源模块1，根据反应时间的升序为电源模块命名，则电源模块N的反应时间是最长的。Wherein, it should be specially noted that the N power modules are named as power module 1 to power module N in sequence according to their response time from shortest to longest. That is, the power module with the shortest response time is named power module 1, and the power modules are named according to the ascending order of response time, and the response time of power module N is the longest.
S2：通过服务器CPU分别向N个电源模块发送主从调整指令。S2: The server CPU sends master-slave adjustment instructions to the N power modules respectively.
S3：电源模块收到主从调整指令后，依序按照设定的反应时间进行主从供电模式的调整。S3: After receiving the master-slave adjustment command, the power module adjusts the master-slave power supply mode in sequence according to the set reaction time.
具体的，电源模块1通过单片机内的第二检测单元侦测电源备援指示信号；若电源备援指示信号为低电平，则认定当前未有电源模块被设置为主电源；此时，将电源备援指示信号设置为输出信号，并通过电源备援指示信号输出高电平将电源模块1设置为主电源。至此，系统的主电源已设定完毕。最后，将其它N-1个电源模块依序进行备援设置。Specifically, the power supply module 1 detects the power backup indication signal through the second detection unit in the single-chip microcomputer; if the power backup indication signal is low level, it is determined that no power supply module is currently set as the main power supply; at this time, the The power backup indication signal is set as an output signal, and the power supply module 1 is set as the main power supply through the power backup indication signal outputting a high level. So far, the main power of the system has been set. Finally, the other N-1 power supply modules are sequentially set for backup.
作为示例的，其它N-1个电源模块依序进行备援设置的过程如下：As an example, the process of sequentially performing backup settings for other N-1 power modules is as follows:
为了便于说明，将其它N-1个电源模块中的任一电源模块命名为电源模块n。For ease of description, any power module among the other N-1 power modules is named power module n.
首先，电源模块n通过单片机内的第二检测单元侦测电源备援指示信号；若电源备援指示信号为高电平，则认定当前有电源模块被设置为主电源；将电源备援指示信号设置为输入侦测功能，并通过侦测高电平将电源模块n设置为电源模块n-1的从电源。First, the power supply module n detects the power backup indication signal through the second detection unit in the single-chip microcomputer; if the power backup indication signal is high level, it is determined that a power supply module is currently set as the main power supply; the power backup indication signal Set it as the input detection function, and set the power module n as the slave power supply of the power module n-1 by detecting the high level.
通过上述设置，实现了电源模块2为从-1电源、电源模块3为从-2电源、电源模块4为从-3电源……电源模块N为从-(N-1)电源。Through the above settings, the power supply module 2 is the slave-1 power supply, the power module 3 is the slave-2 power supply, the power module 4 is the slave-3 power supply...the power module N is the slave-(N-1) power supply.
S4：当前作为主电源的电源模块发生异常时，停止输出并对其它正常的电源模块进行初始化设置。S4: When the power module currently serving as the main power supply is abnormal, stop the output and initialize the other normal power supply modules.
具体来说：电源模块1发生异常时，停止输出，将其电源备援指示信号转化为低电平；将电源模块1的供电模式由作为主电源的电源备援模式恢复为标准模式；其它N-1个电源模块侦测到电源备援指示信号为低电平后，分别将其供电模式恢复为标准模式。Specifically: when the power supply module 1 is abnormal, stop the output, and convert its power backup indication signal to low level; restore the power supply mode of the power supply module 1 from the power backup mode as the main power supply to the standard mode; other N - One power supply module restores its power supply mode to the standard mode after detecting that the power backup indication signal is at a low level.
S5：对当前正常的电源模块依序按照设定的反应时间进行主从供电模式的调整。S5: Adjust the master-slave power supply mode for the currently normal power supply modules in sequence according to the set response time.
