具体实施方式
为使本公开的目的、技术方案和优点更加清楚明白，下文中将结合附图对本公开的实施例进行详细说明。需要说明的是，在不冲突的情况下，本公开中的实施例及实施例中的特征可以相互任意组合。
通常，BBU通过外部设备提供的时钟源，完成与不同类型的射频天线之间的时间同步，但是，若BBU与射频天线之间的通信链路发生异常(例如，通信链路发生断链故障等)，则BBU与射频天线之间就无法进行时间的精准同步，易导致采集到的与射频天线对应的测量信息或配置维护信息无法与BBU的实时运行时间对齐，使得整个通信网络的时钟异常，BBU只能通过局部分析或单侧的推测来定位射频天线可能存在的异常，降低了异常定位的效率。
例如，图1示出根据本公开的实施例的BBU与射频天线之间的连接关系示意图。如图1所示，基站机房110中安装有多种设备：传输装置111、第一网络机柜112、第二网络机柜113、电源114、备用电池115、空调设备116和监控系统117等。
第一网络机柜112包括基带处理单元(BBU)1121，该基带处理单元1121通过光纤与射频拉远单元(RRU)121相连接，该RRU 121与射频天线122通信连接(例如，RRU 121与射频天线122通过馈线相连接)。
第二网络机柜113包括：分布单元(Distributed Unit，DU)1131和中心单元(Centralized Unit，CU)1132。DU 1131与有源天线单元(Active Antenna Unit，AAU)130之间通过光纤连接。
需要说明的是，基带处理单元1121通过外部设备(例如，全球定位系统(Global Positioning System，GPS)设备等)与射频天线122之间完成时钟同步；DU 1131也可以通过GPS设备与AAU 130之间完成时钟同步。
若基带处理单元1121与射频天线122之间的通信链路发生断链故障，则基带处理单元1121只能通过单侧局部分析或单侧的推测来定位射频天线122(或RRU 121)可能存在的异常，降低了异常定位的效率。同样地，若DU 1131与AAU 130之间的通信链路发生断链故障，则DU 1131也只能通过单侧局部分析或单侧的推测来判断可能存在的异常，无法对故障进行精准定位。
本公开提供一种维测时间的确定方法、装置、设备、电子设备和存储介质，用以解决上述问题。
图2示出根据本公开的实施例的维测时间的确定方法的流程示意图。该维测时间的确定方法可应用于第一设备。如图2所示，本公开实施例中的方法包括但不限于以下步骤。
步骤S201，获取第一设备的实时运行时间和预先存储的第一时间。
第一时间为第一设备与第二设备完成时钟同步时的绝对时间，第二设备与第一设备通信连接。
步骤S202，依据第一时间和实时运行时间，确定与测量维护信息对应的维测时间。
测量维护信息是第一设备对通信参数进行测量时和/或第二设备对第一设备的工作参数进行配置维护时获得信息。
例如，该第一设备的工作参数可以包括：第一设备中的芯片电压、时钟锁定信息、中频模块的工作参数、射频模块的工作参数和天线参数中的至少一种。在实际工作的过程中，第一设备可以通过一键采集的方式获取第二设备对其工作参数进行配置维护的配置信息，以 方便后续使用。
在本实施例中，通过第二设备与第一设备通信连接，并获取第一设备的实时运行时间和预先存储的第一时间，其中，第一时间为第一设备与第二设备完成时钟同步时对应的绝对时间，以方便对时间信息的处理；依据第一时间和实时运行时间，确定与测量维护信息对应的维测时间，能够获得精准的维测时间，以使第一设备对通信参数进行测量时，和/或，第二设备对第一设备的工作参数进行配置维护时，获得的测量维护信息可以与维测时间进行准确对接，提升测量维护信息的准确性，方便对通信故障的准确定位，提升第一设备的安全性。
在一些具体实现中，在执行步骤S201中的获取所述第一设备的实时运行时间和预先存储的第一时间之前，还包括：每间隔预设时长，更新第一时间。
预设时长是可以根据实际需求进行设定的时长，例如，预设时长为8小时、9小时等。以上对于预设时长仅是举例说明，可根据实际需要进行具体的设定，其他未说明的预设时长也在本公开的保护范围之内，在此不再赘述。
通过每间隔预设时长就对第一时间进行更新，能够使更新后的第一时间体现不同时段内的第一设备的芯片的实时计数情况，提升后续对故障时长的定位准确性。
在一些具体实现中，在执行步骤S201中的获取第一设备的实时运行时间和预先存储的第一时间之前，还包括：在确定第一设备与第二设备之间的通信链路存在异常的情况下，依据第一设备执行复位操作前或第一设备掉电前的时间，更新第一时间。
第一设备执行复位操作前或第一设备掉电前的时间，能够更精准的对时间进行记录，提升对第一设备的故障时长的定位准确性。复位操作是第一设备进行断电后再上电，以使第一设备可以重新启动，减少第一设备因可能存在的异常而导致的通信故障的发生比例。异常包括：第一设备与第二设备之间的通信链路发生中断，或，第一设备自身存在故障等异常。
需要说明的是，获取该芯片的计数时间，能够明确第一设备具 体在哪个时刻进行了复位操作，从而依据该芯片的计数时间更新预先存储的第一时间，以使获得的更新后的第一时间能够表征第一设备具体在哪个时刻进行了复位操作，方便后续对第一设备可能发生故障的时段进行准确定位，从而对第一设备可能发生的异常进行排查和处理。
在一些具体实现中，步骤S202中的依据第一时间和实时运行时间，确定测量维护信息对应的维测时间，可以采用如下方式实现。
图3示出根据本公开的实施例的维测时间的校准方法的流程示意图。
如图3所示，该维测时间的校准方法包括但不限于如下步骤。
步骤S301，依据获取到的历史抖动时间信息，确定校准系数。
历史抖动时间信息可以包括：主频偏差信息，或，多次试验获得的时延抖动信息等。
步骤S302，依据更新后的第一时间和实时运行时间，确定待校准时间。
更新后的第一时间能够表征与第一设备进行复位操作的时刻对应的绝对时间，通过将该更新后的第一时间与实时运行时间进行加和处理，能够使获得的待校准时间体现第一设备从其复位开始，到目前获得测量维护信息的时刻之间的时长(即，待校准时间)。
步骤S303，依据校准系数对待校准时间进行校准，获得维测时间。
例如，可以将待校准时间与校准系数进行加和处理，或乘积处理，从而获得测量维护信息对应的维测时间。
通过校准系数对待校准时间进行校准，能够使维测时间更准确，以保证该维测时间能够与测量维护信息进行准确对应，提升测量维护信息的准确性。
在一些具体实现中，实时运行时间包括：定时更新的时间和第一设备中的芯片基于核计数功能确定的实时时间，定时更新的时间存储在第二寄存器中，第一设备中的芯片基于核计数功能确定的实时时间存储在第三寄存器中。
步骤S201中的获取第一设备的实时运行时间，可以采用如下方 式实现：
在确定获得第一设备执行复位操作的标识或第一设备主动发起掉电重启的标识的情况下，将第三寄存器中的时间累加至第二寄存器中；在确定第一设备完成复位操作或第一设备掉电重启的情况下，清空第三寄存器，第一设备中的芯片开始重新计时，将重新计时的实时时间存储至第三寄存器中；依据第二寄存器中存储的时间和第三寄存器中存储的时间，确定实时运行时间。
第一设备执行复位操作的标识用于表征第一设备即将进行复位操作，需要对第三寄存器中的时间进行记录，以保证时间的连续性。第一设备主动发起掉电重启的标识用于表征第二设备需要进行掉电重启，同样需要将第三寄存器中的时间进行保存记录。
通过在确定获得第一设备执行复位操作的标识或第一设备主动发起掉电重启的标识的情况下，将第三寄存器中的时间累加至第二寄存器中，能够保证第二寄存器中存储的时间的延续性，方便后的对时间的追溯。在确定第一设备完成复位操作或第一设备掉电重启的情况下，清空第三寄存器，第一设备中的芯片开始重新计时，将重新计时的实时时间存储至第三寄存器中，以使第三寄存器中的时间能够体现芯片的实时计数情况，进而基于第二寄存器中存储的时间和第三寄存器中存储的时间，确定实时运行时间，例如，将第二寄存器中存储的时间和第三寄存器中存储的时间相加，获得实时运行时间，能够保证该实时运行时间的准确性。
在一些具体实现中，步骤S202中的依据所述第一时间和所述实时运行时间，确定与测量维护信息对应的维测时间，包括：获取第一设备与第二设备完成时钟同步之后第一设备与第二设备之间的通信链路处于正常状态下的运行时长；依据通信链路处于正常状态下的运行时长和实时运行时间，确定故障时长；依据故障时长和第一时间，确定维测时间。
使用实时运行时间减去通信链路处于正常状态下的运行时长，以获得故障时长，通过该故障时长能够表征第一设备可能发生故障的时间长度，以方便对该第一设备的测量维护信息进行时间对齐。
进一步地，可将该故障时长与第一时间进行加和处理，使获得的维测时间能够体现第一设备可能发生故障的故障时长，因其中的第一时间是预先存储的、能够表征第一设备与第二设备完成时钟同步时的绝对时间，提升维测时间的准确性。
在一些具体实现中，在执行步骤S201中的获取第一设备的实时运行时间和预先存储的第一时间之前，还包括：获取第一设备上电的第一时刻；获取第一设备与第二设备完成时钟同步的第二时刻；依据第一时刻和第二时刻，确定时间偏差。
时间偏差用于对维测时间进行校准。例如，时间偏差可以采用第二时刻与第一时刻之间的差值表示，以表征第一设备从上电开始，到其完成与第二设备之间的时钟同步的时差，从而使该时间偏差能够进一步对第一设备的维测时间进行精准校准，提升维测时间的准确性。
例如，可以将该时间偏差加入到维测时间中，以使该维测时间能够表征第一设备从上电开始的时间，提升维测时间的精准性。
需要说明的是，第一设备上电的第一时刻也可以是该第一设备在发生故障之后，重新启动并上电时的时刻，以方便第一设备对其维测时间进行精准估计，提升对故障时长的推测准确性。
在一些具体实现中，步骤S201中的获取第一设备的实时运行时间，包括：获取第一设备中的芯片记录的时间信息；依据预设时间转换规则对芯片记录的时间信息进行转换，获得实时运行时间。
预设时间转换规则可以包括：将芯片记录的时间信息进行不同时间单位之间的转换，以使获得的实时运行时间能够符合第一设备的使用需求。
例如，第一设备的芯片从某个时刻开始计数，获得计数数量(例如，1024个计数点)，然后，基于预先定义的每个计数点表示的时间单位(例如，5毫秒(ms)等)，则可计算获得第1024个计数点对应的实时运行时间为：1024*5ms＝5120ms＝5.12秒(s)，从而获得该第一设备的芯片记录的时间长度为5.12秒。
通过采用上述第一设备的芯片对时间进行记录的方式，能够方便第一设备内部的使用(例如，不同程序之间的调用等)，进一步地， 依据预设时间转换规则对芯片记录的时间信息进行转换，获得实时运行时间，能够使其他设备可以获知该第一设备的具体运行的时长，以方便其他设备与该第一设备之间进行时间同步，提升时钟同步的准确性。
在一些具体实现中，获取第一设备中的芯片记录的时间信息，包括：依据预设应用场景和计数位宽，对芯片运行过程中的时间进行记录，获得芯片记录的时间信息。
预设应用场景可以包括：应用于不同网元设备之间的同步场景，或，应用于需要精准计时的场景等。
网元设备可以包括：射频拉远设备、基站、服务器和终端中的至少两种。计数位宽可以包括以二进制数表示的16比特(bit)、32bit或64bit等二进制数的长度，也可以包括以十六进制数表示的不同长度的计数长度等。以上对于计数位宽仅是举例说明，可根据实际需要进行具体的设定，其他未说明的计数位宽都在本公开的保护范围之内，在此不再赘述。
通过预设应用场景和计数位宽对芯片运行过程中的时间进行记录，能够保证获得的时间信息可以适用于不同的预设应用场景，以使该芯片记录的时间信息更准确，满足不同应用场景中的使用需求，提升计数准确性。
在一些具体实现中，第一时间存储在第一寄存器中，第一寄存器设置于内存、闪存和固态硬盘(Solid State Disk，SSD)中。第一设备为射频拉远设备，第二设备为基带处理单元BBU。
射频拉远设备包括：有源天线单元AAU、射频拉远单元RRU和pRRU(pico RRU)中的任意一种。第一寄存器、第二寄存器和第三寄存器均还可以采用内存(flash)、闪存和SSD中的任意一种来实现。例如，在确定第一设备支持掉电自愈的情况下，可将上述三个寄存器可以部署在闪存中；在面向软件复位的应用场景中，上述三个寄存器可以部署在保留的内存区域。
在确定第一设备支持掉电自愈的情况下，需要设置掉电类型标签，该掉电类型标签用于标识所述设备是主动掉电，还是由于不可预 测的外部因素导致的掉电。
需要说明的是，以上对于寄存器的类别仅是举例说明，可根据实际需要进行具体的设定，其他未说明的寄存器的类别也在本公开的保护范围之内，在此不再赘述。
通过将第一时间存储在第一寄存器中，使射频拉远设备在其与BBU之间的通信链路发生异常的情况下，能够基于该第一时间和射频拉远设备的实时运行时间，确定与测量维护信息对应的维测时间，提升测量维护信息的准确性。
在一些具体实现中，在执行步骤S201中的获取第一设备的实时运行时间和预先存储的第一时间之前，还包括：采用网络时间协议(Network Time Protocol，NTP)网络时间协议NTP和/或网络测量和控制系统的精密时钟同步协议(Precision Clock Synchronization Protocol，PCSP)，与第二设备进行时钟同步。
NTP为应用层协议，用以使客户端和服务器之间进行时钟同步的协议。在本实施例中，可以采用NTP使第一设备与第二设备之间进行时钟同步，以保证两种不同类型的设备之间可以同步工作，提升工作效率。
网络测量和控制系统的精密时钟同步协议通过一个同步信号周期性的对通信网络中所有节点(例如，第一设备和第一设备等)的时钟进行校正同步，以使通信网络中设备之间能够精确同步，提升通信效率。
图4示出根据本公开的实施例的维测时间的确定方法的流程示意图。如图4所示，“t”表示时间轴，在时间轴上的不同的时刻处，射频拉远设备完成不同的操作。
在t0时刻，射频拉远设备上(即上述第一设备)电，开始工作。
在t1时刻，射频拉远设备中的芯片(如，ARM芯片、FPGA芯片和EPLD芯片中的任意一种)开始启动核计数功能，用于对射频拉远设备中的实时运行时间(即本地运行时间)进行计数。
t1时刻与t0时刻之间的差值很小(例如，t1-t0约为100ms)，该差值能够体现维测时间的准确性。具体实现时，可通过存储在不同 的寄存器中的时间信息确定该差值，以方便对维测时间做进一步的校准。
在t1时刻至t2时刻之间，射频拉远设备需要完成软件版本的加载，并与基带处理单元之间进行时钟的同步，该段时间内，射频拉远设备与基带处理单元之间的通信链路是处于异常状态。
当到达t2时刻时，射频拉远设备与基带处理单元之间完成时钟同步。此时，射频拉远设备需要记录与t2时刻对应的绝对时间Taboslute2(例如，将该绝对时间Taboslute2存储到第一寄存器中，该第一寄存器设置于内存或闪存中)。
射频拉远设备可以采用NTP和/或网络测量和控制系统的精密时钟同步协议，与基带处理单元进行时钟同步。
需要说明的是，在射频拉远设备与基带处理单元之间完成时钟同步之后，射频拉远设备正常工作。
在一些具体实现中，射频拉远设备还可以采用公式(1)计算t3时刻之前的与某个测量维护信息对应的维测时间Ttest-1：
Ttest-1＝Taboslute2+(T1-T2)+X           (1)
其中，Ttest-1表示t3时刻之前的、与某个测量维护信息对应的维测时间，测量维护信息包括：射频拉远设备对通信参数进行测量时的信息，和/或，基带处理单元对射频拉远设备的工作参数进行配置维护时获得的信息。
T1表示射频拉远设备中的芯片在t0时刻之后记录的实时运行时间对应的时长。例如，T1＝ttest-1-t0，T1可以存储在第一寄存器中。ttest-1表示与维测时间对应的时刻。
T1是基于预设时间转换规则对射频拉远设备中的芯片记录的时间信息进行转换获得的时间。T2表示第二寄存器中存储的、在时钟同步之后，且通信链路处于正常状态下的时长。例如，如图4所示，射频拉远设备中的芯片在t2时刻～t3时刻之间累计的时间长度。X表示校验系数，该校验系数是基于获得的历史抖动时间信息(例如，主频偏差信息或多次进行试验获得的时延抖动信息等)确定的系数。
例如，Ttest-1、T1、T2、Taboslute2均可以采用位宽为32bit的无符 号数表示，单位为秒(second)。射频拉远设备中的芯片的核计数功能对应的寄存器、第一寄存器和第二寄存器均需要进行防溢出的处理，以防止数据累计的位数超过32bit。上述对于各个寄存器的位宽(如，32bit)仅是举例说明，可根据实际需要进行具体设定(例如，可以采用16bit或64bit的位宽等)，其他未说明的寄存器的位数也在本公开的保护范围之内，在此不再赘述。
在一些具体实现中，第一寄存器不需要进行周期性维护，减少了中央处理器(Central Processing Unit，CPU)的额外开销。在面向软件复位的应用场景中，第一寄存器可以部署在保留内存区；在面向掉电自愈的应用场景中，第一寄存器可以部署在闪存中。
由于自愈断电是瞬态发生的，而其他的外部断电的时间是无法被感知和补偿的，因此，可通过掉电类别标志位区分是外部掉电或软件主动发起的掉电，并分类别进行处理。
当到达t3时刻时，射频拉远设备与基带处理单元之间的通信链路出现异常(例如，通信链路中断，或，该射频拉远设备出现故障等)，此时，射频拉远设备无法与基带处理单元进行精准的时钟同步，但射频拉远设备中的芯片的核计数功能一直处于正常工作状态，即射频拉远设备中的芯片保持持续计数状态不变。
需要说明的是，当射频拉远设备与基带处理单元之间的通信链路的异常时长超过预设时长(例如，3秒或5秒等)时，射频拉远设备会自动执行复位操作，但在执行复位操作之前，会将射频拉远设备的芯片的实时运行时间记录下来，例如，将该射频拉远设备的芯片的实时运行时间设置为芯片计数时间，并使用该芯片计数时间对第一寄存器中存储的Taboslute2进行累计更新，从而获得更新后的第一时间，即Taboslute4，如图4所示，Taboslute4表示与t4时刻对应的绝对时间。
在t4时刻，射频拉远设备执行复位操作。
在t4时刻～t5时刻之间，射频拉远设备需要完成软件版本的加载等操作。
当到达t5时刻时，射频拉远设备与基带处理单元之间完成软件版本的加载等操作，射频拉远设备中的芯片开始启动核计数功能，用于 对射频拉远设备中的实时运行时间进行计数。
t5时刻与t4时刻之间的差值很小(例如，t5-t4约为100ms)，该差值能够体现维测时间的准确性。具体实现时，可通过存储在不同的寄存器中的时间信息确定该差值，以方便对维测时间做进一步的校准。
例如，将t4时刻对应的绝对时间Taboslute4记录在第二寄存器中，将t5时刻对应的绝对时间记录在第三寄存器中，其中，第二寄存器中存储的是第一设备定时更新的时间，第三寄存器中存储的是第一设备中的芯片基于核计数功能确定的实时时间；通过第二寄存器与第三寄存器之间的差值，能够体现维测时间的准确性。
在t5时刻至t6时刻这段时间内，由于没有完成时钟同步，因此，射频拉远设备与基带处理单元之间的通信链路处于异常状态。
在到达t6时刻时，射频拉远设备与基带处理单元之间进行时钟的同步，此时，射频拉远设备需要记录与t6时刻对应的绝对时间Taboslute6(例如，将该绝对时间Taboslute6存储到第一寄存器中，该第一寄存器设置于内存或闪存中)。
在t4时刻之后，且射频拉远设备与基带处理单元之间的通信链路处于异常状态的情况下，射频拉远设备还可以采用公式(2)计算t6时刻之前的与某个测量维护信息对应的维测时间Ttest-2：
Ttest-2＝Taboslute4+T′1+X               (2)
Ttest-2表示t4时刻(或t5时刻)之后、与某个测量维护信息对应的维测时间。
T′1表示在t4时刻(或t5时刻)之后、射频拉远设备中的芯片记录的与实时运行时间对应的时长，例如，T′1＝ttest-2-t4(或T′1＝ttest-2-t5)。ttest-2表示与维测时间对应的时刻。
在本实施例中，通过利用射频拉远设备中的芯片的核计数功能，以及预先存储在第一寄存器中的能够表征射频拉远设备与基带处理单元之间时钟同步的绝对时间，确定射频拉远设备的维测时间，能够解决射频拉远设备与基带处理单元之间的通信链路发生异常时的维测时间无法与基带处理单元的时间进行精准对齐的问题。该维测时间 的确定方法可适用于各种不同的射频拉远设备，能够通过升级软件版本的方式，使射频拉远设备与基带处理单元之间的时间对齐一致，提升测量维护信息的准确性，方便对通信故障的准确定位，提升射频拉远设备的安全性。
