Description
本申请要求在2020年12月22日提交中国专利局、申请号为202011532924.8、发明名称为“整机柜服务器中子节点的异常断电保护系统、方法及设备”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。
本申请涉及电子技术领域，特别涉及一种整机柜服务器中子节点的异常断电保护系统、方法、电子设备及计算机可读存储介质。
在服务器行业内，单节点服务器的供电通常为CRPS(Common Redundant Power Supplies，公共冗余电源)的1+1冗余设计，即，若其中一个CRPS电源发生故障或出现异常掉电，则另外一个CRPS电源可单独给整个服务器节点供电，以便保护服务器数据不受电源故障或异常掉电而丢失。
但是，在整机柜服务器中，其子节点服务器的供电通常依靠于整机柜后端的供电铜排，由供电铜排给整机柜内的所有子节点同时供电。子节点的供电夹子一旦离开供电铜排，该子节点服务器系统就会直接断电。因此，整机柜服务器无法仿照单节点服务器做类似的电源1+1冗余供电设计。
一般在正常关机操作下，用户会首先按压子节点的电源开关，此时系统主电供电网络会按照预先设计的时序有序掉电(在等待主电电源完全关闭后再关闭待机电源)，而有序掉电的过程中包含了数据存储等操作，可避免服务器数据丢失。
然而，在整机柜服务器的机房中，维护工程师经常会在服务器正常工作时，未按压电源按钮就直接拔出子节点机箱，由此造成了异常断电。这使得子节点主板端的输入电源直接从正常工作电位掉至零电压，板端各级供电网络触发欠压保护而自动关闭，因此子节点的待机电源和系统主电电源将同时关闭，未遵守系统原定的关机掉电时序，进而导致子节点系统内的数据丢失。 同时，子节点内供电单元带载异常掉电也可能在短时间内产生反向电压，损坏系统内的敏感电子元器件。
鉴于此，提供一种解决上述技术问题的方案，已经是本领域技术人员所亟需关注的。

为了对本申请实施例中的技术方案进行更加清楚、完整地描述，下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行介绍。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
在整机柜服务器中，其子节点服务器的供电通常依靠于整机柜后端的供电铜排，由供电铜排给整机柜内的所有子节点同时供电。子节点的供电夹子一旦离开供电铜排，该子节点服务器系统就会直接断电。因此，整机柜服务器无法仿照单节点服务器做类似的电源1+1冗余供电设计。
一般在正常关机操作下，用户会首先按压子节点的电源开关，此时系统主电供电网络会按照预先设计的时序有序掉电(在等待主电电源完全关闭后再关闭待机电源)，而有序掉电的过程中包含了数据存储等操作，可避免服务器数据丢失。
然而，在整机柜服务器的机房中，维护工程师经常会在服务器正常工作时，未按压电源按钮就直接拔出子节点机箱，由此造成了异常断电。这使得 子节点主板端的输入电源直接从正常工作电位掉至零电压，板端各级供电网络触发欠压保护而自动关闭，因此子节点的待机电源和系统主电电源将同时关闭，未遵守系统原定的关机掉电时序，进而导致子节点系统内的数据丢失。同时，子节点内供电单元带载异常掉电也可能在短时间内产生反向电压，损坏系统内的敏感电子元器件。
鉴于此，本申请提供了一种整机柜服务器中子节点的异常断电保护方案，可有效解决上述技术问题。
参见图1所示，本申请实施例公开了一种整机柜服务器中子节点的异常断电保护系统，整机柜服务器通过供电铜排为各子节点供电，异常断电保护系统包括逻辑控制模块101以及插拔触发模块102；
插拔触发模块102用于通过金属探针检测子节点的供电夹子与供电铜排在第二插接深度处的接触状态，转换生成检测信号并发送至逻辑控制模块101；其中，第二插接深度大于第三插接深度且不大于第一插接深度，第一插接深度和第三插接深度分别对应于供电铜排的最大可插接深度处和浅层边缘处；
逻辑控制模块101用于在根据检测信号判定供电夹子脱离供电铜排的第二插接深度处之后，在供电夹子脱离供电铜排的第三插接深度处之前，先后依次关闭子节点的主电电源和待机电源，以便子节点执行正常关机掉电逻辑。
需要指出的是，申请人注意到，业内为保障供电的接触稳定，子节点的供电夹子(例如常用的“鳄鱼夹”)在正常使用时会深插入供电铜排以便保障充分接触。一般地，供电夹子插入供电铜排的最大可插接深度D
max在20～30mm范围内，也就是说，供电夹子与供电铜排有20～30mm的接触深度。
因此，子节点服务器的完全拔出是有一定过程的：从供电夹子脱离供电铜排的最大可插接深度D
max处，同时也是本申请中的第一插接深度D
1处，直至供电夹子脱离供电铜排的浅层边缘处，同时也是本申请中的第三插接深度D
3处。并且，申请人还发现，供电夹子与供电铜排的整个分离过程所持续的时间一般至少在几百毫秒以上，甚至是1秒以上。由此，申请人发现，可以利用上述分离过程所造成的时间机会，基于逻辑控制模块101抢在系统完全断电之前执行正常关机掉电逻辑。
具体的，本申请中的插拔触发模块102，具体是用于检测子节点供电夹子与供电铜排第二插接深度D
2处的接触状态，即，一旦子节点的供电夹子离开供电铜排的第二插接深度处，插拔触发模块102便会变换输出对应的检测信号。其中，0＝D
3<D
2≤D
1＝D
max。
同时，本申请中逻辑控制模块101分别与子节点主板上的主电电源和待机电源连接，一旦发现供电夹子与供电铜排的第二插接深度处脱离，逻辑控制模块101便可判定供电夹子与供电铜排的分离过程刚刚开始，子节点正在但还未完全被拔出，因此可立即控制子节点的主电电源关闭，并在主电电源关闭之后控制待机电源关闭。
通过控制主电电源先于待机电源关闭，即执行了正常关机掉电逻辑。在正常关机掉电逻辑的设计中，系统内部数据会自动得以保存，由此便可有效避免了系统数据丢失。同时，各级供电网络有序掉电，避免了因欠压而损坏内部的敏感元器件，保障了电路安全。
还需要说明的是，依据现代电子器件已达到的数据处理时钟频率水平，逻辑控制器件执行关闭主电电源的操作最多仅需几十毫秒，远小于1秒，两者不在同一个数量级。因此，从实际操作层面，逻辑控制器件完全可以做到在供电夹子完全脱离供电铜排的第三插接深度处之前，先后依次关闭子节点的主电电源和待机电源，即本方案具有充分的可行性。
需要说明的是，本领域技术人员需要在(0，D
max]范围内合理设置第二插接深度D
2的大小。根据上述基于时间机会的检测原理可知：D
2越大，可用于先后关闭主电电源、待机电源的总时间裕量越多，因此D
2不宜过小。
在一个具体实施例中，第二插接深度可等于第一插接深度，即D
2＝D
1＝D
max。此时，金属探针检测的便是供电夹子与供电铜排在最大可插接深度处的接触状态。如此虽然可获取最大的总时间裕量，但是容易出现误动作：例如，一旦子节点服务器因自然晃动导致供电夹子稍微位移而脱离了最大可插接深度，则此时金属探针便会误报。
为此，在另一个具体实施例中，第二插接深度略小于第一插接深度，例如，可令D
2＝0.8·D
max。如此，便可为供电夹子提供了(D
2，D
max]范围内的误动作区间，当供电夹子在该插接深度范围内活动时，金属探针不会改变电位输出状态，从而避免了误报、提高了准确度。
可见，本申请所提供的整机柜服务器中子节点的异常断电保护系统，在子节点服务器被误拔时，可基于金属探针探测到供电夹子与供电铜排分离过程的初始时刻，并利用该分离过程所造成的时间机会，在完全断电之前先后控制主电电源、待机电源关闭，实现正常关机掉电逻辑，从而有效避免了系统数据的丢失，并防止了异常掉电产生的反向电压损坏系统内的敏感电子元器件，保障了系统电路安全。
作为一种具体实施例，本申请实施例所提供的整机柜服务器中子节点的异常断电保护系统在上述内容的基础上，插拔触发模块102包括金属探针以及与金属探针的第一端连接的电平转换电路；
金属探针与子节点的供电夹子平行安装，且金属探针第二端相对于机壳的凸出距离小于供电夹子，以使在供电夹子插入至供电铜排的第二插接深度处时，金属探针的第二端恰好与供电铜排的第三插接深度处相接触。
对照参见图2～4，图2为本申请实施例公开的一种子节点服务器的安装示意图；图3为本申请实施例公开的一种供电夹子插入至供电铜排第二插接深度处的状态示意图；图4为本申请实施例公开的一种供电夹子插入至供电铜排某一中间深度的状态示意图。图中，201为子节点服务器，202为供电铜排的电源母排，203为供电铜排的接地母排，204为子节点服务器的供电夹子，205为金属探针。
如图2所示，供电铜排竖直安装，包括电源母排和接地母排。子节点服务器的机壳后方设置有两个鳄鱼夹即供电夹子，两个鳄鱼夹可分别插入电源母排和接地母排而取电。
此外，金属探针安装在供电夹子附近对应于供电铜排的一个位置，但是，金属探针凸出于机壳的长度较小，当鳄鱼夹插入至供电铜排的第二插接深度处时，金属探针才刚好可与供电铜排的第三插接深度处相接触，具体可参见图3。
此时，金属探针第一端的输出电位取决于其所接触的供电铜排的电位。图3中金属探针所接触的是供电铜排中的电源母排，则输出电位为高电平。若所接触的是供电铜排中的接地母排，则输出电位为低电平。
而当鳄鱼夹并没有插入至供电铜排的第二插接深度处，而是小于第二插 接深度的某个中间深度处时，金属探针便无法接触到供电铜排而处于悬空状态，具体可参见图4。此时金属探针第一端的输出电位既不是高电平也不是低电平，而是为高阻态电位。
参见图5，本申请实施例还公开了一种电平转换电路的电路结构。
作为一种具体实施例，本申请实施例所提供的整机柜服务器中子节点的异常断电保护系统在上述内容的基础上，电平转换电路包括相连的上拉电阻Rs和可控接地开关Q，上拉电阻Rs与可控接地开关Q的公共端作为电平转换电路的输出端与逻辑控制模块101连接；上拉电阻Rs的另一端与待机电源连接；可控接地开关Q的另一端接地；
可控接地开关Q的控制端与金属探针的第一端连接，以使当金属探针的第二端与供电铜排的第三插接深度处相接触时，可控接地开关Q闭合，当金属探针的第二端悬空时，可控接地开关Q断开。
需要说明的是，为了便于理解，图5中具体以一个等效开关S来表示金属探针。容易理解的是，当金属探针第二端悬空时，可控接地开关Q为常开状态，电平转换电路输出端的电平状态被上拉电阻Rs拉至高电平；当金属探针第二端与供电铜排的第三插接深度处接触时，金属探针的输出电位控制可控接地开关Q闭合，电平转换电路输出端的电平状态被可控接地开关Q拉低至低电平。
由此，基于本实施例所提供的电平转换电路，当检测信号由低电平变为高电平即出现上升沿时，便可判定子节点服务器的供电夹子已脱离至供电铜排的第二插接深度处。此外，本领域技术人员还可在上述电平转换电路的基础上增加滤波防抖电路等以进一步提高信号准确性，本申请对此并不进行限定。
作为一种具体实施例，本申请实施例所提供的整机柜服务器中子节点的异常断电保护系统在上述内容的基础上，供电铜排包括电源母排和接地母排，金属探针安装在机壳上与电源母排的对应位置处，以便在供电夹子插入至供电铜排的第二插接深度处时，金属探针的第二端恰好与电源母排的第三插接深度处相接触；可控接地开关Q为NMOS管。
具体地，若金属探针与电源母排对应安装，则当金属探针与电源母排的第三插接深度处接触时，金属探针的输出电位为高电平，故此，本实施例对 应选择了高电平有效的NMOS管作为可控接地开关Q。
类似地，本领域技术人员也可以将金属探针与接地母排对应安装，当金属探针与接地母排的第三插接深度处接触时，金属探针的输出电位为低电平，因此，当对应选择低电平有效的PMOS管作为可控接地开关Q。
作为一种具体实施例，本申请实施例所提供的整机柜服务器中子节点的异常断电保护系统在上述内容的基础上，逻辑控制模块101包括子节点的主板上的CPLD(Complex Programmable Logic Device，复杂可编程逻辑器件)。
具体地，CPLD是服务器主板上普遍使用的一种重要逻辑器件。它具有编程灵活、集成度高、适用范围宽等优点，可实现较大规模的电路设计，因此被广泛应用。因此，本实施例中可具体利用子节点服务器主板上的CPLD来作为逻辑控制模块101。
作为一种具体实施例，本申请实施例所提供的整机柜服务器中子节点的异常断电保护系统在上述内容的基础上，CPLD与子节点的电源按键连接，CPLD还用于：
在接收到来自电源按键的关机指令后，先后依次关闭主电电源和待机电源。
具体地，异常断电保护机制与正常关机操作的断电机制彼此并不冲突。无论是在用户按下电源按键之后，还是在检测到用户异常误拔子节点服务器后，本实施例中的CPLD均会先后关闭主电电源和待机电源，以执行正常关机掉电逻辑，保护系统数据安全和元器件安全。
如图6，作为一种具体实施例，本申请实施例所提供的整机柜服务器中子节点的异常断电保护系统在上述内容的基础上，逻辑控制模块101还包括子节点的主板上的BMC(Baseboard Management Controller，基板管理控制器)，BMC用于：
在根据检测信号判定供电夹子脱离供电铜排的第二插接深度处之后，生成针对本次异常断电的日志记录。
具体地，BMC是服务器主板上普遍使用的另一种重要逻辑器件。它可以通过传感器监控设备的运行状态，通过独立的连接线路和系统管理员进行通信，可以在机器未开机的状态下，对机器进行包括系统状态监视、重启、重新供电、断电、固件升级等底板控制操作。
本实例中，插拔触发模块102同样与BMC连接。为了便于后续故障分析，BMC可在判定供电夹子脱离供电铜排的第二插接深度处之后，立刻将本次异常断电记录在日志中。
参见图7所示，本申请实施例公开了一种整机柜服务器中子节点的异常断电保护方法，整机柜服务器通过供电铜排为各子节点供电；该方法应用于与子节点的主电电源和待机电源连接的逻辑控制模块101，主要包括：
S301：实时接收插拔触发模块102发送的检测信号；插拔触发模块102通过金属探针检测子节点的供电夹子与供电铜排在第二插接深度处的接触状态，并转换生成检测信号。
其中，第二插接深度大于第三插接深度且不大于第一插接深度，第一插接深度和第三插接深度分别对应于供电铜排的最大可插接深度处和浅层边缘处。
S302：根据检测信号判断供电夹子是否脱离供电铜排的第二插接深度处；若是，则进入S303。
S303：在供电夹子脱离供电铜排的第三插接深度处之前，先后依次关闭主电电源和待机电源，以便子节点执行正常关机掉电逻辑。
可见，本申请实施例所公开的整机柜服务器中子节点的异常断电保护方法，在子节点服务器被误拔时，可基于金属探针探测到供电夹子与供电铜排分离过程的初始时刻，并利用该分离过程所造成的时间机会，在完全断电之前先后控制主电电源、待机电源关闭，实现正常关机掉电逻辑，从而有效避免了系统数据的丢失，并防止了异常掉电产生的反向电压损坏系统内的敏感电子元器件，保障了系统电路安全。
