相关申请的交叉引用
本申请要求在2020年11月09日提交中国专利局，申请号为202011239502.1，发明名称为“一种服务器电源供电保护方法及装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本公开涉及服务器供电保护领域，特别是涉及一种服务器电源供电保护方法及装置。
背景技术
随着科技的进步，服务器的供电需求越来越大，服务器的供电方法越来越多，目前服务器电源的供电是通过一个总电源通过一个供电系统多个电压调节系统连接多个线路进行多个负载装置的同时供电。
目前的服务器电源供电保护方法是，只要当其中一个线路输出端发生故障，系统检测到故障后马上关闭供电系统的使能信号，当供电系统的使能信号被关闭后，供电系统停止供电，整个系统处于断电状态，此工作原理是当线路输出端发生故障时，线路的输入端会因为故障而使电平升高，总而影响整个系统的供电状态，故停止整个系统的供电来对系统进行保护。
此种方法对服务器电源供电保护过于繁琐，当其因为电压调节系统本身或者使能信号出现问题时，对系统断电是没有必要的，反而会影响系统的运行，增加系统排错和后期的维护次数，并且不利于进行故障修复时对故障的定位分析。
发明内容
在一些实施方式中，公开了一种服务器电源供电保护方法，包括：
基于服务器电源的供电系统中至少一条、例如每条线路的电压调节模块，为至少一个、例如每个电压调节模块提供监控单元，监控单元分别与电压调节模块的输入端和基板管理控制器连接；

在一些实施方式中，当总供电模块的使能信号被拉低时，供电系统断电。在一些实施方式中，当所述出现故障的电压调节模块所属线路的使能信号被关闭时，所属线路断电，其他线路的电压调节模块继续输出电压。
在一些实施方式中，当电压调节模块出现故障时，若电压调节模块输入端的电流或电压过高，例如是大于所述电压调节模块的工作电流或工作电压的1.2倍，则基板管理控制器检测到的所述电压信号状态为异常。在一些实施方式中，若电压调节模块输出端不影响其他输入端的电流或电压，例如是电压调节模块输出端的电流或电压不大于所述电压调节模块的工作电流或工作电压的1.2倍，则基板管理控制器检测到的所述电压信号为正常。
在一些实施方式中，若电压调节模块输入端电流过高，例如是大于所述电压调节模块的工作电流的1.2倍，所述监控单元将电压调节模块输入端的电流信号转换成电压信号传输给基板管理控制器。
在一些实施方式中，当基板管理控制器检测到的电压信号状态为异常时，供电系统判断该基板管理控制器所在的电压调节模块会影响其他线路的电压调节模块。在一些实施方式中，当基板管理控制器检测到的电压信 号状态为正常时，供电系统判断所述基板管理控制器所在的电压调节模块不会影响其他线路的电压调节模块。
在一些实施方式中，所述电压调节模块设有故障显示单元，当电压调节模块出现故障时，电压调节模块输出端不输出电压，故障显示电路接通，LED灯亮。在一些实施方式中，当电压调节模块无故障时，电压调节模块输出端输出电压，故障显示电路不接通，LED灯不亮。
在一些实施方式中，若所述电压调节模块无故障时，所述基板管理控制器控制复杂可编程逻辑器件抬高总供电模块的使能信号，总供电模块对系统进行供电。
在一些实施方式中，公开了一种服务器电源供电保护装置，包括：
总供电模块和多个电压调节模块，至少一个、例如每个电压调节模块中设有监控单元、基板管理控制器、复杂可编程逻辑器件和故障显示单元，所述监控单元包括两个精密电阻和一个电流电压监控芯片，所述故障显示单元包括三极管、调节电阻、LED灯；
所述总供电模块通过线缆分别与多个电压调节模块连接；
所述监控单元通过总线与基板管理控制器连接，监控单元通过导线和电压调节模块输入端连接，两个所述精密电阻两端分别通过导线与电流电压监控芯片和电压调节模块输入端连接；

图2是本公开的一些实施方式中，服务器电源供电保护装置示意图；
图3是本公开的一些实施方式中，服务器电源供电保护装置中电压调节模块的电路结构图。
具体实施方式
下面结合附图对本公开的较佳实施例进行详细阐述，以使本公开的优点和特征能更易于被本领域技术人员理解，从而对本公开的范围做出更为清楚明确的界定。
见图1，提供了本公开的一个实施例，包括：
一种服务器电源供电保护方法200，包括：
为服务器电源的供电系统中至少一条、例如每条线路的至少一个、例如每个电压调节模块，提供监控单元，监控单元分别与电压调节模块的输入端和基板管理控制器连接。在一些实施方式中，为服务器电源的供电系统中至少一条、例如每条线路的至少一个、例如每个电压调节模块，提供故障显示单元，故障显示单元与电压调节模块的输出端连接。
系统上电后，总供电模块输出12V电压给电压调节模块，在供电过程中，基板管理控制器接收电压调节模块在电压调节模块故障时发送的故障信号。若电压调节模块其输出端正常，则控制复杂可编程逻辑器发送使能信息给总供电模块，总供电模块正常供电；若电压调节模块其输出端异常，即发生故障(条件201)，则该线路为故障线路，第一电压调节模块向所述第一基板管理控制器发送故障信号(动作210)。在电压调节模块中引入监控单元，电流通过监控单元的电阻和电流电压监控芯片转换成电压信号传递给基板管理控制器，电压调节模块的基板管理控制器接收到的来自监控单元的电压信号(动作220)，判断其是否电压过高。当基板管理控制器接收到的电压信号为异常状态，则控制复杂可编程逻辑器件关闭总供电模块的使能信号(动作231)，此时整个系统断电，服务器宕机。当基板管理控制器接收到的电压信号为正常状态，则控制复杂可编程逻辑器件关闭该 基板管理控制器对应的线路，即故障线路的使能信号(动作232)，此时故障线路断电，其他线路正常供电。在一些实施方式中，基板管理控制器接收到的电压信号大于其工作电压的1.2倍，则将其接收到的电压信号判断为异常状态，即收到了异常的电压信号。在一些实施例中，基板管理控制器接收到的电压信号小于或等于其工作电压的1.2倍，则将其接收到的电压信号判断为正常状态(或说，非异常状态)，即收到了正常(或说，非异常)的电压信号。在一些实施方式中，基板管理控制器为可输出高电平和低电平的芯片。在一些实施方式中，基板管理控制器接收复杂可编程逻辑器件的指令来输出高电平或低电平。在一些实施方式中，监控单元持续传送电压信号到基板管理控制器。当系统中因为电压调节模块本身或者负载装置发生异常时，基板管理控制器检测其输出端为异常，然后对来自监控单元的电压信号进行检测，此时因为系统中是因为电压调节模块本身或者负载装置发生异常，所以输入端电流电压不受输出端影响，所以来自监控单元的电压信号正常，此时基板管理控制器控制复杂可编程逻辑器只关闭该故障线路的使能信号，该故障线路断电，但是其他线路正常运行，这样避免了服务器不必要的宕机，提升了服务器的可靠性。
当系统输出端故障时，电压调节模块的输出端不输出电压，故障显示电路的三极管接通，LED灯点亮，这样对故障线路进行了标识，便于后期服务器的维护。
第二方面，见图2和图3，本说明书实施例还提供一种服务器电源供电保护的装置1，包括：
总供电模块20和多个电压调节模块10，多个电压调节模块10例如连接处理器31,32、内存33、显卡34，所述多个电压调节模块10中设有监控单元110、基板管理控制器120、复杂可编程逻辑器件130、故障显示单元140，所述监控单元110包括两个精密电阻R4和R3和一个电流电压监控芯片111，所述故障显示单元140包括三极管Q3、调节电阻R5、LED灯D1；

供电正常时，电压调节模块10的复杂可编程逻辑器件130控制金氧半场效晶体管(MOSFET)Q1和MOSFET Q2的开合来输出电压；
当电压调节模块10出现故障时，输入端101电压信号发送至基板管理控制器120，基板管理控制器120接收所述信号，输入端101电流信号流过精密电阻R3并通过电流电压监控芯片111转换成电压信号经过总线传输给基板管理控制器120，基板管理控制器120接收所述电压信号，若基板管理控制器120接收到的电压信号异常，基板管理控制器120通过总线控制复杂可编程逻辑器件130对总供电模块20的使能信号进行拉低，以便对其他线路的电压调节模块10进行保护，若基板管理控制器120接收到的电压信号正常，基板管理控制器120通过总线控制复杂可编程逻辑器件130对其所在的电压调节模块10的使能信号进行关闭，则出现故障的电压调节模块10所在线路断电，故障显示单元的三极管Q3接通，LED灯点亮，其他线路继续输出电压。本申请的一些实施例中，区别于现有技术，具有以下效果：
1)增加了监控单元提升了服务器的可靠性，使服务器灵活判断每个故障信号，避免不必要的服务器宕机。
2)增加了故障显示电路，能够快速定位发生故障的线路，提高了服务器的可维护性。
3)本方法还可以在其他服务器的电源应用场合中使用。
在一些实施方式中，提供的方法与装置能够解决当服务器中是由于硬件本身的问题造成的输出端故障时，服务器供电系统断电使服务器宕机而影响服务器的可靠性，增加服务器的维护次数以及故障排查难度大的问题。
在一些实施方式中，提供的方法与装置能够使服务器灵活应对不同种类的故障信号，提升服务器的可靠性，避免服务器进行不必要的宕机，提高了服务器后期的维护性。
上述方法与装置中所述的各个模块，可全部或部分通过软件、硬件及其组合来实现。上述各模块可以硬件形式内嵌于或独立于服务器中的处理器中，也可以以软件形式存储于服务器中的存储器中，以便于处理器调用执行以上各个模块对应的操作。
