具体实施方式Detailed ways
下文中将参考附图并结合实施例来详细说明本申请的实施例。Embodiments of the present application will be described in detail below with reference to the drawings and in combination with the embodiments.
在相关技术中，通过外部电源向服务器中的多个电源模块供电，以外部电源为12V电源，第一个电源模块P3V3、第二个电源模块P1V8、第三个电源模块P1V0为例，如图1所示，外部电源与三个电源模块依次连接，每个电源模块包括：EN(enable，使能端)和PG(powergood，输出正常信号)，可以理解的是，在12V电源上电后，按预设顺序驱动输出，分别是P3V3,P1V8,P1V0，在12V电源掉电的情况下，三个电源模块下电的顺序与上电顺序相同，例如：每个电源模块的下电间隔时长大于40毫秒。In related technologies, an external power supply is used to supply power to multiple power modules in the server. Take the external power supply as a 12V power supply, the first power module P3V3, the second power module P1V8, and the third power module P1V0 as an example, as shown in the figure 1, the external power supply is connected to three power modules in sequence, and each power module includes: EN (enable, enabling terminal) and PG (powergood, outputting a normal signal). It is understandable that after the 12V power supply is powered on, Drive the output according to the preset order, which are P3V3, P1V8, and P1V0 respectively. In the case of a 12V power failure, the power-off sequence of the three power modules is the same as the power-on sequence. For example, the power-off interval of each power module is longer than 40 milliseconds.
但是在实际的应用场景中，未考虑异常掉电尤其是服务器高负载工作状态下的异常掉电时序，在服务器高负载工作过程中异常掉电，各电源模块的电平会急速下降到零，三个电源模块的下电间隔时长无法满足预设时长，例如：40毫秒。为解决上述问题，在本实施例中提供了一种服务器下电时序控制系统，如图2所示，包括：第一控制模块10、第二控制模块20和多个电源模块30；其中，第一控制模块10和第二控制模块20分别与多个电源模块30连接，第一控制模块10与第二控制模块20连接；第一控制模块10用于确定服务器的负载状态，在服务器掉电且负载状态为第一状态的情况下，控制第一控制模块10中的多个储能模块向多个电源模块30放电，以控制多个电源模块30按照预设时序下电；在服务器掉电且负载状态为第二状态的情况下，由第二控制模块20向多个电源模块30输出电平，以控制多个电源模块30按照预设时序下电。However, in the actual application scenario, abnormal power-off, especially the abnormal power-off sequence under the high-load working state of the server, is not considered. When the server is abnormally powered off during high-load work, the power level of each power module will drop to zero rapidly. The power-off interval of the three power modules cannot meet the preset duration, for example: 40 milliseconds. In order to solve the above problems, a server power-off sequence control system is provided in this embodiment, as shown in FIG. 2 , including: a first control module 10, a second control module 20 and a plurality of power supply modules 30; A control module 10 and a second control module 20 are respectively connected to a plurality of power supply modules 30, and the first control module 10 is connected to the second control module 20; the first control module 10 is used to determine the load status of the server, when the server is powered off and When the load state is the first state, control the multiple energy storage modules in the first control module 10 to discharge to the multiple power supply modules 30, so as to control the multiple power supply modules 30 to be powered off according to the preset sequence; when the server is powered off and When the load state is the second state, the second control module 20 outputs levels to the multiple power supply modules 30 to control the multiple power supply modules 30 to be powered off according to a preset sequence.
例如：第一控制模块10接收服务器的负载状态，确定服务器的负载状态为第一状态，第一控制模块10通过其中的储能模块向多个电源模块30供电，供电时长根据下电时序确定，例如：多个电源模块30按照连接顺序从左往右依次下电，则储能模块向电源模块30的供电时长，就由左到右依次增长。For example: the first control module 10 receives the load state of the server, determines that the load state of the server is the first state, the first control module 10 supplies power to a plurality of power supply modules 30 through the energy storage module therein, and the power supply duration is determined according to the power-off sequence, For example, if multiple power modules 30 are powered off from left to right according to the connection sequence, the duration of power supply from the energy storage modules to the power modules 30 will increase from left to right.
需要说明的是，本申请的说明书和权利要求书及上述附图中的术语“第一”、“第二”等是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。It should be noted that the terms "first" and "second" in the description and claims of the present application and the above drawings are used to distinguish similar objects, but not necessarily used to describe a specific sequence or sequence.
在实际的应用场景中，第二控制模块20可以是CPLD(复杂可编程逻辑器件)，也可以是MCU(微控制单元)等可以进行控制的微处理芯片。In an actual application scenario, the second control module 20 may be a CPLD (Complex Programmable Logic Device), or a microprocessing chip such as an MCU (Micro Control Unit) that can be controlled.
具体地，CPLD中的逻辑块类似于一个小规模PLD，通常一个逻辑块包含4～20个宏单元，每个宏单元一般由乘积项阵列、乘积项分配和可编程寄存器构成。每个宏单元有多种配置方式，各宏单元也可级联使用，因此可实现较复杂组合逻辑和时序逻辑功能。对集成度较高的CPLD，通常还提供了带片内RAM/ROM的嵌入阵列块。可编程互连通道主要提供逻辑块、宏单元、输入/输出引脚间的互连网络。输入/输出块(I/O块)提供内部逻辑到器件I/O引脚之间的接口。Specifically, a logic block in a CPLD is similar to a small-scale PLD. Usually, a logic block contains 4 to 20 macrocells, and each macrocell generally consists of a product term array, product term allocation and programmable registers. Each macro-unit has multiple configuration modes, and each macro-unit can also be used in cascade, so more complex combinational logic and sequential logic functions can be realized. For CPLDs with a higher degree of integration, embedded array blocks with on-chip RAM/ROM are usually provided. Programmable interconnection channels mainly provide interconnection networks between logic blocks, macrocells, and input/output pins. Input/Output Blocks (I/O Blocks) provide the interface between internal logic and device I/O pins.
CPLD需要根据实际需要而自行构造逻辑功能的数字集成电路。其基本设计方法是借助集成开发软件平台，用原理图、硬件描述语言等方法，生成相应的目标文件，通过下载电缆(“在系统”编程)将代码传送到目标芯片中，实现设计的数字系统。CPLD needs to construct digital integrated circuits with logic functions according to actual needs. The basic design method is to use the integrated development software platform to generate corresponding target files by means of schematic diagrams and hardware description languages, and transmit the code to the target chip through the download cable ("in-system" programming) to realize the designed digital system. .
在实际的应用场景中，利用集成开发软件写入硬件描述语言后进行编译，最后给出逻辑电路的输入激励信号，进行仿真，在输出结果符合预设条件的情况下，进行管脚输入、输出锁定(7128的64个输入、输出管脚可根据需要设定)，最后生成代码，通过下载电缆将代码传送并存储在CPLD芯片中。In the actual application scenario, use the integrated development software to write the hardware description language and then compile it. Finally, the input excitation signal of the logic circuit is given for simulation. When the output result meets the preset conditions, the pin input and output are performed. Lock (the 64 input and output pins of 7128 can be set according to the needs), finally generate the code, transmit the code through the download cable and store it in the CPLD chip.
在一种可选的方式中，如图3所示，第一控制模块10包括：基板管理控制器40、检测模块50、充电模块60和多个储能模块70；其中，检测模块50和多个储能模块70与基板管理控制器40连接，充电模块60与多个储能模块70连接，多个储能模块70与多个电源模块30连接；检测模块50，用于确定服务器的负载功率，并将负载功率发送给基板管理控制器40；基板管理控制器40，用于基于负载功率确定服务器的负载状态；以及在服务器掉电且负载状态为第一状态的情况下，控制多个储能模块70向多个电源模块30放电，在服务器掉电且负载状态为第二状态的情况下，向第二控制模块20发送指示信息，在服务器处于通电状态的情况下，控制充电模块60向多个储能模块70充电，其中，指示信息用于指示第二控制模块20控制多个电源模块30按照预设时序下电。In an optional manner, as shown in FIG. 3 , the first control module 10 includes: a baseboard management controller 40, a detection module 50, a charging module 60, and multiple
在实际的应用场景中，充电模块60可以是充电电路。In an actual application scenario, the charging module 60 may be a charging circuit.
可以理解的是，在服务器领域，通常通过负载功率的大小来确定服务器的负载状态，由此可以得出第一状态和第二状态的区分方法：基板管理控制器40，在负载功率大于预设功率阈值的情况下，确定服务器的负载状态为第一状态，在负载功率小于预设功率阈值的情况下，确定服务器的负载状态为第二状态。It can be understood that in the field of servers, the load state of the server is usually determined by the magnitude of the load power, and thus the method for distinguishing the first state from the second state can be obtained: the baseboard management controller 40, when the load power is greater than the preset In the case of the power threshold, it is determined that the load state of the server is the first state, and when the load power is less than the preset power threshold, it is determined that the load state of the server is the second state.
其中，预设功率阈值可以基于实际的工作需要预先设置。Wherein, the preset power threshold may be preset based on actual work needs.
需要进行说明的是，基板管理控制器中包括16位元或32位元微控制器以及用于数据储存的随机存取存储器、用于非挥发性数据储存的快闪记忆体和韧体。通过基板管理控制器可以用于系统状态监视；重启、重新供电、断电等底板控制等。It should be noted that the baseboard management controller includes a 16-bit or 32-bit microcontroller, random access memory for data storage, flash memory and firmware for non-volatile data storage. The baseboard management controller can be used for system status monitoring; baseboard control such as restart, re-power, and power-off.
第二控制模块20包括多个通用输入输出端口，其中，所述多个通用输入输出端口用于输入电平或输出电平。The second control module 20 includes multiple general input and output ports, wherein the multiple general input and output ports are used for input level or output level.
需要说明的是，在服务器处于通电状态的情况下，第二控制模块20中的多个通用输入输出端口接收外部电源输入的电信号，在服务器掉电且负载状态处于第二状态的情况下，第二控制模块20控制其中的多个通用输入输出端口转变信号传输方向，由输入变为输出，从而使第二控制模块20向多个电源模块30输出电信号从而控制多个电源模块30按照时序下电。It should be noted that, when the server is powered on, the multiple general-purpose input and output ports in the second control module 20 receive electrical signals input from an external power supply; when the server is powered off and the load status is in the second state, The second control module 20 controls the multiple general-purpose input and output ports to change the signal transmission direction from input to output, so that the second control module 20 outputs electrical signals to the multiple power supply modules 30 to control the multiple power supply modules 30 according to the sequence Power off.
在另一种可选的方式中，可以由基板管理控制器40直接与多个电源模块30连接，替换掉第二控制模块20，在这种方式中，由基板管理控制器40向多个电源模块30输出电平，以控制多个电源模块30按照预设时序依次下电。In another optional way, the baseboard management controller 40 can be directly connected to multiple power supply modules 30 to replace the second control module 20. In this way, the baseboard management The output level of the module 30 is used to control multiple power supply modules 30 to be powered off sequentially according to a preset time sequence.
可以理解的是，输出电信号的时长和多个电源模块30的下电时刻相关，例如：第二控制模块20接收第一控制模块10发送的服务器的负载状态，服务器的负载状态为第二状态，第二控制模块20通过其中的多个通用输入输出端口向多个电源模块30输出电平，以多个电源模块30按照连接顺序从左往右依次下电，则第二控制模块20向电源模块30输出电平的时长，就由左到右依次增长。It can be understood that the duration of the output electrical signal is related to the power-off time of multiple power supply modules 30, for example: the second control module 20 receives the load status of the server sent by the first control module 10, and the load status of the server is the second status , the second control module 20 outputs levels to the multiple power supply modules 30 through the multiple general-purpose input and output ports. The duration of the output level of the module 30 increases sequentially from left to right.
在一种可选的方式中，通用输入输出端口的数量与电源模块30的数量相同，通过一一对应的方式精准的控制每一个电源模块30的下电时刻，以达到预设下电时序。In an optional manner, the number of general-purpose input and output ports is the same as the number of power modules 30, and the power-off time of each power module 30 is accurately controlled in a one-to-one correspondence to achieve a preset power-off sequence.
多个储能模块70中包括多个电容，所述多个电容对应的额定电容由小到大的顺序与所述电源模块下电时序一致。The plurality of
需要说明的是，储能模块70中至少包括一个电容，用于存储电能，例如：多个电源模块30按照连接顺序从左往右依次下电，则储能模块70向电源模块30的供电时长，就由左到右依次增长，储能模块70中电容的额定电容大小顺序由左往右依次增大。It should be noted that the
在实际的应用场景中，第一控制模块10先根据检测模块50检测到的服务器的负载功率，判断服务器的当前负载状态是第一状态还是第二状态。In an actual application scenario, the first control module 10 first determines whether the current load state of the server is the first state or the second state according to the load power of the server detected by the detection module 50 .
在服务器处于第二状态的情况下，则第一控制模块10可以通过通知CPLD接管下电时序。当CPLD管脚GPIO1、GPIO2、GPIO3监测到异常掉电时，将输入改为输出，控制EN来使下电时序满足。When the server is in the second state, the first control module 10 can take over the power-off sequence by notifying the CPLD. When the CPLD pins GPIO1, GPIO2, and GPIO3 detect abnormal power-off, the input is changed to output, and EN is controlled to meet the power-off sequence.
在服务器处于第一状态的情况下，则第一控制模块10将模拟开关打开，将预充电完成的电容切换到各电源芯片的使能(EN)通路上，保证第一状态下掉电时，有足够的泄放时间。电容的大小可以按照下电的先后顺序，由小到大排布。When the server is in the first state, the first control module 10 opens the analog switch, and switches the pre-charged capacitors to the enable (EN) paths of each power supply chip to ensure that when the power is off in the first state, There is enough time to vent. The size of the capacitors can be arranged according to the order of power-off, from small to large.
通过引入第一控制模块和第二控制模块，第一控制模块和第二控制模块对不同负载状态下的服务器利用不同的控制方式来控制服务器中的多个电源模块按照预设时序下电，其中，第一控制模块通过控制多个储能模块向多个电源模块放电，第二控制模块通过向多个电源模块输出电平来延长电源模块的上电时长，进而控制电源模块的下电时刻，因此，可以解决服务器在异常掉电的情况下，其中的多个电源模块不能保证按照预设时序下电的问题，进而达到了服务器在异常掉电的情况下，其中的多个电源模块仍然可以按照预设时序下电的效果。By introducing the first control module and the second control module, the first control module and the second control module use different control methods for servers under different load states to control multiple power modules in the server to be powered off according to a preset sequence, wherein , the first control module controls the discharge of multiple energy storage modules to multiple power modules, and the second control module prolongs the power-on time of the power modules by outputting levels to multiple power modules, and then controls the power-off time of the power modules, Therefore, it can solve the problem that in the case of abnormal power failure of the server, the multiple power modules in it cannot be guaranteed to be powered off according to the preset sequence, and then achieve the problem that in the case of abnormal power failure of the server, the multiple power modules in it can still The effect of powering off according to the preset timing.
