相关申请的交叉引用
本申请基于申请号为202111174265.X、申请日为2021年10月09日的中国专利申请提出，并要求该中国专利申请的优先权，该中国专利申请的全部内容在此引入本申请作为参考。
技术领域
本公开涉及电子技术领域，尤其涉及一种电压监控方法及装置、电子设备及存储介质。
背景技术
目前的计算机设备往往需要极高的功耗比，因而设备的算力板中的专用集成电路(Application Specific Integrated Circuit，ASIC)芯片对供电电压十分敏感。若由于长时间大功率输出导致线路或元器件老化，或者由于电网抖动等原因，出现偶发瞬时欠压，将导致ASIC芯片异常。即使后续欠压消失，算力板也无法正常工作。
现有的产品中，是通过每10秒主动控制外围接口控制器(Peripheral Interface Controller，PIC)芯片获取一次当前电压，以进行电压的监控，但是缺少对瞬时电压的持续监控。如果遇到瞬时欠压或过压，并不能及时地识别定位。目前针对欠压的情况是通过调整母线电容数目来控制的，但是并没有一种可以长期使用的监控方案。
发明内容

本公开实施例中提供的技术方案，获取算力板上负载的电压值；确定所述电压值是否小于第一取值；当所述电压值小于所述第一取值时，根据所述电压值对电源进行供电保护。通过电压值的获取，以及与第一取值的比对，可确定算力板负载是否存在瞬时欠压，从而减少相关技术中电压值获取周期较长导致对瞬时电压监控的即时性较差的现象。根据即时获取的电压值进行供电保护，可以充分提高不同电压值表征不同电压波动情况下的供电保护灵活性和供电安全性。

图8是根据一示例性实施例示出的一种电压监控方法的流程示意图。
具体实施方式
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本发明实施例相一致的所有实施方式。相反，它们仅是本发明实施例的一些方面相一致的装置和方法的例子。
在本公开实施例使用的术语是仅仅出于描述特定实施例的目的，而非旨在限制本公开实施例。在本公开所使用的单数形式的“一种”、“所述”和“该”也旨在包括多数形式，除非上下文清楚地表示其他含义。还应当理解，本文中使用的术语“和/或”是指并包含一个或多个相关联的列出项目的任何或所有可能组合。
应当理解，尽管在本公开实施例可能采用术语第一、第二、第三等来描述各种信息，但这些信息不应限于这些术语。这些术语仅用来将同一类型的信息彼此区分开。例如，在不脱离本公开实施例范围的情况下，第一信息也可以被称为第二信息，类似地，第二信息也可以被称为第一信息。取决于语境，如在此所使用的词语“如果”可以被解释成为“在……时”或“当……时”或“响应于确定”。
如图1所示，本公开实施例提供一种电压监控方法，包括：
S110：获取算力板上负载的电压值；
S120：确定所述电压值是否小于第一取值；
S130：当所述电压值小于第一取值时，根据所述电压值对电源进行供电保护。
在本公开实施例中，算力板可以为用于提供算力资源的算力板，或者计算机设备中用于提供处理资源的工作电路模组等。负载可以为算力板上的运算模组和/或ASIC芯片等。电源可以为与算力板连接，用于为算力板提供工作电压的外部电源，例如可以为电源模组，也可以为外部的电源等。
在一个实施例中，获取算力板上负载的电压值，可以为获取ASIC芯片等负载的母线上的电压值。这里，可以通过与算力板连接用于向算力板提供控制指令的上位机，和/或，通过位于算力板上的监控模块、处理模块等获取负载的电压值。这里，监控模块、处理模块可以为算力板上的微控制器(Micro Controller Unit，MCU)。
在一个实施例中，第一取值可以为判断负载中发生瞬时欠压的临界值，可以根据电源电压，或者，根据电源电压和负载配置情况进行确定。示例性的，第一取值可以为电源电压的80％，比如在电源电压为220V时，第一取值可以为176V。
在一个实施例中，根据电压值对电源进行供电保护，可以为根据电压值大小不同，分别采取不同的供电保护策略。例如，可以停止电源向算力板供电，或者，也可以调整算力板负载功率等工作参数，或者，启动预设的电压补偿电路等。
如此，不再仅限于按一定周期采集算力板负载的电压值，可以有效提高算力板电压监控的实时性，抑制采集周期较长时导致对瞬时电压异常难以及时定位识别。另外，根据电压值进行供电保护，既可以实现在出现瞬时欠压情况下的智能供电保护，无需人工调试负载端母线电容等器件，又可以结合电压值指示的具体欠压情况，灵活提供供电保护方式。
在一些实施例中，S130可包括：
当电压值小于第一取值且大于第二取值时，降低负载的工作频率以减少电源所需向负载提供的供电功率；其中，第二取值小于第一取值；
和/或，
当电压值小于第二取值时，停止电源向负载供电。
在本公开实施例中，第一取值可以为判断是否出现欠压情况的临界值，第二取值低于第一取值， 可以为判断是否出现严重欠压情况的阈值。示例性的，第一取值可以为电源电压的80％，第二取值可以为电源电压的70％，比如电源的输出电压为220V，则第一取值为176V，第二取值为154V。
在一个实施例中，当前电压值小于第一取值且大于或等于第二取值时，表明当前负载电路出现了瞬时欠压，但并未达到严重欠压，即不会对电源、算力板负载或电路产生较大的瞬时危害。因此，可以通过调整负载的工作参数来消除瞬时欠压，例如可以降低负载工作频率、或者重新分配算力模块的算力资源等，降低负载的工作功率，以减少电源的供电功率，从而保证供电正常与电源以及负载设备的安全。
在一个实施例中，降低负载工作频率，可以为对算力板ASIC芯片中的中央处理器(central processing unit，CPU)进行降频，或者对其他处理器、运算模块等进行降频。
在一个实施例中，当前电压值小于第二取值时，表明当前负载电路处于严重欠压状态，则立即将算力板负载下电，以抑制对电源、负载造成严重损害。
在一个实施例中，可以在电源和负载之间设置电源控制电路，且与上位机或算力板上的监控模块连接，在电压值小于第二取值时，通过电源控制电路将负载下电。
在一个实施例中，算力板还可以包括：电压补偿电路，连接在负载和上位机之间，或者，连接在负载和算力板上监控模块之间。在检测到电压值小于第一取值且大于等于第二取值，或者，检测到电压值小于第二取值时，均可以通过开启电压补偿电路，来消除瞬时欠压情况。如此，可以无需对负载的当前工作状态进行调整改变，从而可以抑制对算力板正常工作进程的影响。
如此，基于电压值和第一取值、第二取值的比对情况，确定具体的瞬时欠压情况，进而针对不同的瞬时欠压情况，可以实现智能调整供电保护策略。例如对于瞬时欠压较小的情况，可以无需断电，通过降频等操作调整负载的欠压情况，抑制对负载正常工作的不必要中断。基于此，可以进一步提高算力板负载供电保护的智能性和灵活性。
在一些实施例中，如图2所示，S110，可包括：
S111：接收算力板上微控制器MCU采集的负载的电压值。
在本公开实施例中，可以通过上位机接收算力板上的微控制器MCU采集的电压值，MCU可以为算力板上的PIC芯片，例如PIC16F1704芯片等。PIC芯片可以通过内置的数模转换(Analog-to-Digital Converter，adc)模块采集负载的实时电压值。例如，如图3所示，通过adc模块的模拟输入引脚AN6连接负载，可以以预设频率采集负载的电压值。这里，预设频率为adc模块的采样频率，例如可以为10000Hz，即每秒采集10000次负载电压值。这里，VDD、VSS为电源连接端，RA0-RA5均为A定义I/O端口，RC0-RC5均为C定义I/O端口，ICSPDAT为串行编程数据I/O端口，ICSPCLK为串行编程时钟端口，AN6为adc模拟输入端口，PIC_EN为控制负载通断电的数字量引脚。
在一个实施例中，算力板的MCU采集电压值后，可以根据电压值和第一取值、第二取值的比对情况，确定具体的欠压情况，进而选择不同的供电保护策略，也可以提供给上位机，由上位机执 行电压值比对以及供电保护指令的下发。
在一个实施例中，MCU可以按一定上报周期，周期性地向上位机提供采集的电压值，例如，上报周期可以为10s或15s等预设时长。以上报周期为10s为例，上位机可以基于MCU每隔10s上报一次10s内采集的所有电压值，确定其中是否存在小于第一取值且大于等于第二取值的电压值。若存在，表明10s内算力板负载电路存在瞬时欠压，则降低负载工作频率，或者，开启算力板上的电压补偿电路等，以减少电源所需向负载提供的供电功率。MCU基于实时采集的电压值，确定电压值是否小于第二取值，若小于第二取值，表明当前出现严重的瞬时欠压，则停止电源向负载的供电。
在一个实施例中，MCU可以按一定上报周期，向上位机提供本上报周期内的最小电压值，例如上报周期为10s时，MCU可以确定10s内采集的电压值最小值，并发送给上位机，上位机基于最小值确定是否小于第一取值且大于等于第二取值，若是，表明存在瞬时欠压，则降低负载工作频率，或者，开启算力板上的电压补偿电路等，以减少电源所需向负载提供的供电功率。另外，MCU基于实时采集的电压值，确定电压值是否小于第二取值，若小于第二取值，表明当前出现严重的瞬时欠压，则停止电源向负载的供电。
在一个实施例中，当电压值小于第一取值时，根据电压值对电源进行供电保护，还可包括：
当电压值小于第一取值时，使用电源的备份与电源一起对负载进行供电。电源的备份包括：算力板上电容，电容在电源供电正常时充电或者不充电，电源供电不正常(例如，供电欠压时)，该电容与电源一起供电。
电源的备份与电源一起供电需要满足供电条件，该供电条件包括但不限于：电源的备份的剩余电量不低于预设值等。
即，电源值小于第一取值且电源的备份满足供电条件，则电源和电源的备份一起向负载供电。
若电压值小于第一取值且电源的备份不满足供电条件，则可以停止电源向负载的供电。
在一个实施例中，上位机可以存储MCU采集的负载的电压值，以记录算力板负载的电压变化情况。
在一些实施例中，MCU通过分压电路与负载的供电输入端并联；电压值被MCU采集之后写入预设存储区域。
在一个实施例中，负载和MCU之间，或者，负载和上位机之间，还可以设置图4所示的分压电路。MCU通过分压电路与负载供电输入端并联，例如，可以为PIC芯片的adc引脚即AN6引脚，通过分压电路与负载的母线连接，从而抑制负载电压直接输入MCU导致电压波动时对MCU造成损害。这里，R1718、R1719、R25、R28、R29、R32均为电阻，C21、C22均为电容，1nF50V代表耐压定值50V，电容量为1nF的电容。
在一个实施例中，MCU通过数模转换adc模块采集实时电压值后，将电压值存储在预设存储区域，例如，将电压值写入算力板上的随机存取存储器(Random Access Memory，RAM)中。如此，可以有效记录MCU采集的电压值，便于上位机获取采集的电压值。
在一些实施例中，如图5所示，S111可包括：
S111a：在达到上报时刻时，接收所述MCU发送的所述预设存储区域内存储的最小值。
在本公开实施例中，上报时刻可以为预设的上报规则指示MCU上报采集的电压值的时刻，例如，按一定上报周期确定的上报时刻等。
在一个实施例中，MCU发送预设存储区域内存储的最小值，可以为确定从上一次上报到当前时刻期间，MCU写入到预设存储区域内的电压值中的最小值。示例性的，达到上报时刻时，MCU确定从上一个上报时刻到当前上报时刻形成的时间段内，写入预设存储区域的电压值中最小值，并将该最小值上报给上位机。该预设存储区域可为闪存区域等。
在一个实施例中，MCU在达到上报时刻，向上位机上报采集的电压值或电压值中的最小值后，清空预设存储区域内存储的电压值，以供重新写入新采集的电压值。如此，可以抑制MCU在达到下一个上报时刻时，仍会通过上一上报时刻前采集的电压值比较确定最小值，导致供电保护出现错误。
在一个实施例中，MCU基于一定的采样频率采集电压值，每采集到一个电压值，与预设存储区域内已存储的历史电压值进行比对，若大于或等于预设存储区域内的历史电压值，则不存储该电压值；若电压值小于预设存储区域内的历史电压值，则将该电压值取代历史电压值写入预设存储区域。如此，MCU基于采集的电压值随时更新预设存储区域内存储的电压值，可以保证预设存储区域内存储的为当前采集的电压值最小值。
如此，在达到上报时刻时，上位机可以直接接收MCU发送的预设存储区域内存储的数值，该数值即为所有采集到的电压值中的最小值。
可以理解的是，MCU还可以在基于采集的电压值随时更新预设存储区域内存储的电压值基础上，每完成一次电压值最小值的上报后，将预设存储区域内存储的电压值重置为预设值，例如预设值可以为电源额定电压值。如此，可以保证不同上报阶段采集的电压值不会相互干扰。
在一个实施例中，上位机接收到最小值后，可以将最小值与第一取值和第二取值比较，当最小值小于第一取值且大于第二取值时，降低负载的工作频率；和/或，当最小值小于第二取值时，停止电源向负载供电。
在一个实施例中，上位机接收到最小值后，可以将最小值与第一取值和第二取值比较，当最小值小于第一取值且大于第二取值时，降低负载的工作频率。MCU实时比对采集的电压值和第二取值，若电压值小于第二取值，MCU停止电源向负载供电。
如此，上位机仅需获取一个最小值即可完成对算力板的供电保护，抑制MCU将采集的全部电压值发送上位机，导致数据传输量和处理量过大，进而占据较多的数据处理资源，影响工作效率。
在一些实施例中，上报时刻可包括以下至少之一：
根据上报周期确定的时刻；
检测到上报触发事件确定的时刻。
在本公开实施例中，根据上报周期确定上报时刻，可以为将上报周期结束时对应的时刻作为上报时刻，例如，上报周期为10s时，则每10s上报一次预设存储区域内存储的最小值。如此，可以 降低上位机的工作负荷，抑制持续实时获取电压值对上位机的传输和处理负担。
在一个实施例中，当上报周期为10s时，MCU可以确定10s内采集的电压值最小值，并发送给上位机，上位机基于最小值确定是否小于第一取值且大于等于第二取值，若是，表明存在瞬时欠压，则降低负载工作频率，或者，开启算力板上的电压补偿电路等，以减少电源所需向负载提供的供电功率。另外，MCU基于实时采集的电压值，确定电压值是否小于第二取值，若小于第二取值，表明当前出现严重的瞬时欠压，则停止电源向负载的供电。如此，由于上位机仅用于检测较为轻微的瞬时欠压情况，不会对算力板和电源产生即时的严重损害，因此上位机可以周期性地获取MCU采集的电压值最小值，并确定是否需要调整负载工作频率。基于此，可以大大降低上位机和MCU均需实时采集处理电压值造成的数据处理资源浪费，减轻工作负荷。
在一个实施例中，检测到上报触发事件时，对应的时刻作为上报时刻，例如，上报触发事件可以为，采集的电压值达到一定阈值，表明出现了一定程度的瞬时欠压，则向上位机上报数据；或者，上报触发事件也可以为检测到负载的工作电流、工作电压等工作参数达到一定阈值，或者检测到负载电路的工作参数出现一定程度的波动，例如变化达到30％以上，则将电压值上报给上位机，供上位机确定是否出现严重的瞬时欠压情况。
在一些实施例中，第一取值可以为：
根据电源的供电情况确定的供电电压值；
或者，根据获取的历史电压值确定的。
在本公开实施例中，用于确定是否出现瞬时欠压情况的第一取值，可以根据电源供电情况确定，例如，根据电源额定电压确定，或者，根据电源额定电压和算力板负载的使用情况确定。示例性的，若电源额定电压为220V，则第一取值可以为额定电压的80％，即176V；或者，若根据额定电压220V和算力板负载的使用情况，当算力板负载使用率较高时，第一取值可以取较高的值，例如180V，当算力板负载使用率较低时，第一取值可以取较低的值，例如170V。
在一个实施例中，根据获取的历史电压值确定第一取值，可以为算力板MCU获取过的所有历史电压值的平均值确定，例如，确定获取的所有历史电压值的平均值，并确定该平均值的90％为第一取值，或者，也可以根据获取的所有历史电压值中低于电源额定电压的电压值平均值，确定第一取值。如此，可以使第一取值更加贴合所在算力板的负载与电源的实际运行情况，提高电压监控和供电保护的灵活性和准确性。
如图6所示，本公开实施例提供一种电压监控装置，装置包括：
获取单元10，被配置为获取算力板上负载的电压值；
确定单元20，被配置为确定电压值是否小于第一取值；
保护单元30，被配置为当电压值小于第一取值时，根据电压值对电源进行供电保护。
在一些实施例中，保护单元30，被配置为：
当电压值小于第一取值且大于第二取值时，降低负载的工作频率以减少电源所需向负载提供的 供电功率；其中，第二取值小于第一取值；
和/或，

在一些实施例中，获取单元10，被配置为：
接收算力板上微控制器MCU采集的负载的电压值。
在一些实施例中，MCU通过分压电路与负载的供电输入端并联；电压值被MCU采集之后写入预设存储区域。
在一些实施例中，获取单元10，被配置为：
在达到上报时刻时，接收MCU发送的预设存储区域内存储的最小值。
在一些实施例中，上报时刻包括以下至少之一：
根据上报周期确定的时刻；
检测到上报触发事件确定的时刻。
在一些实施例中，第一取值为：
根据电源的供电情况确定的供电电压值；
或者，
根据获取的历史电压值确定的。
以下结合上述任一实施例提供一个具体示例：
如图7所示，本公开实施例通过算力板端MCU即PIC16F1704芯片内置的adc，以10000Hz的频率实时监控电压，并在PIC端记录20s内的最高和/或最低电压，以供上位机的控制软件读取。这样通过更新算力板的PIC芯片固件，可以实现对算力板端电压的实时监控。负载异常时，上位机可以通过PIC芯片内的电压数据，有效定位出电源不良，减少了运维工作的难度和工作量；同时，负载运行时，上位机可以通过MCU内的电压数据，在发现电压欠压时，提出警告，并做相应补救措施，防止设备因为供电异常而损坏。
在一个实施例中，如图8所示：
1.硬件设计上：将算力板负载的母线电压经过分压电阻后，给到PIC芯片的adc引脚上。
2.PIC芯片固件上：通过PIC中adc的连续采集中断功能，保证PIC以10000Hz以上的频率做电压采集工作，并将数据存储下来，待上位机获取。
3.上位机软件上：每10s从PIC芯片端获取一次历史电压数据，发现电压比预期低一定值后，及时通过降频等操作，降低负载功率，保证供电正常与电源以及负载设备的安全。
4.上位机向PIC芯片设置一个最高与最低允许工作电压值；PIC芯片如果发现电压不在这个范围内，直接通过控制电路，将负载下电，以保证保护工作的实时性。
