Description

一种电源控制方法、装置及设备
本申请要求于2021年2月23日提交中国国家知识产权局、申请号为202110202024.5、申请名称为“一种电源控制方法、装置及设备”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。
技术领域
本申请涉及光通信技术领域，尤其涉及一种电源控制方法、装置及设备。
背景技术
光纤传输作为目前主流的通信传输方案，在企业、家庭终端等场景中应用极为广泛，光网络单元(Optical Network Unit，ONU)作为光纤到户(Fiber To The Home，FTTH)的承载终端节点，在整个光网络中分布十分广泛。随着芯片的集成度越来越高、ONU在家居场景中易于安装的客户诉求越来越强烈，ONU设备逐渐走向小型化；此外，ONU设备的功能越来越强大，导致ONU设备整机功耗密度急剧增大。因此，设备小型化和功耗增大，将导致ONU设备单位能量密度增加，电子元器件工作温度也随之明显提高。
光收发一体组件(bi-directional optical subassembly，BOSA)作为ONU设备的核心器件，且是温度敏感器件。ONU设备工作温度直接影响到BOSA的工作温度，同时影响BOSA使用寿命。但是，如何降低BOSA工作温度，提高BOSA使用寿命，目前还没有更好的优化方案。
发明内容
本申请实施例提供了一种电源控制方法、装置及设备，可以通过动态控制BOSA电源的供电时间来达到降低BOSA功耗和工作温度的目的。
第一方面，本申请实施例提供了一种电源控制方法，所述方法应用于光网络单元ONU，所述ONU包括光收发一体组件BOSA、为所述BOSA供电的BOSA电源、用于控制所述BOSA是否发光的第一控制端、以及用于控制所述BOSA电源是否供电的第二控制端，所述方法包括：
针对所述ONU的至少一个上行发送周期，基于上行发送的开启时间确定第一控制信号生效的第一时间，所述第一控制信号用于所述第一控制端控制所述BOSA发光；
基于所述第一时间确定第二控制信号生效的第二时间，所述第二时间早于所述第一时间，所述第二控制信号用于所述第二控制端控制所述BOSA电源供电；
在所述第二时间使所述第二控制信号生效。
也就是说，在该方法中，针对ONU的每个上行发送周期，可以在BOSA开始发光之前提前打开BOSA电源，即基于第一时间确定第二时间，且第二时间早于第一时间，从而在保证了BOSA正常工作的前提下，降低了BOSA功耗，降低了BOSA工作温度，提高了BOSA使用寿命。
在一种可能的实现方式中，所述基于上行发送的开启时间确定第一控制信号生效的第一时间，包括：
根据所述ONU的工作模式和第一时钟信号，确定所述第一时间；其中，所述ONU的工作模式包括所述第一控制端周期性地控制所述BOSA发光，所述第一时钟信号为所述第一控制端 和第二控制端共用的时钟信号。
也就是说，在该实现方式中，可以基于ONU的工作模式和第一时钟信号确定第一时间，提高了确定第一时间的准确性。
在一种可能的实现方式中，所述第一控制信号具体用于所述ONU中的光物理层PHY驱动所述BOSA发光。
也就是说，在该实现方式中，第一控制端可以向ONU中的光PHY发送第一控制信号，光PHY根据接收到的第一控制信号驱动BOSA发光。
在一种可能的实现方式中，所述基于所述第一时间确定第二控制信号生效的第二时间，包括：
获取第一时间差，所述第一时间差为所述第一时间与所述第二时间之间的设定差值；
基于所述第一时间与所述第一时间差，确定所述第二时间。
也就是说，在该实现方式中，第一时间差指的是BOSA电源开始供电和BOSA开始发光之间的时间差，为了保证BOSA能够正常发光，BOSA电源可以在BOSA开始发光之前开始供电，故而第一时间差可以大于0。
在一种可能的实现方式中，还包括：
基于所述第一时间确定第三控制信号生效的第三时间，所述第三控制信号用于所述第一控制端控制所述BOSA停止发光；
基于所述第三时间确定第四控制信号生效的第四时间，所述第四时间晚于所述第三时间，所述第四控制信号用于所述第二控制端控制所述BOSA电源停止供电；
在所述第四时间使所述第四控制信号生效。
也就是说，在该实现方式中，针对ONU的每个上行发送周期，除了可以在BOSA开始发光之前提前打开BOSA电源之外，还可以在BOSA停止发光之后关闭BOSA电源，即基于第三时间确定第四时间，且第四时间晚于第三时间，从而进一步降低了BOSA功耗，降低了BOSA工作温度，提高了BOSA使用寿命。
在一种可能的实现方式中，所述第三控制信号具体用于所述ONU中的光PHY驱动所述BOSA停止发光。
也就是说，在该实现方式中，第一控制端向ONU中的光PHY发送第三控制信号，光PHY根据接收到的第三控制信号驱动BOSA停止发光。
在一种可能的实现方式中，所述基于所述第三时间确定第四控制信号生效的第四时间，包括：
获取第二时间差，所述第二时间差为所述第四时间与所述第三时间之间的设定差值；
基于所述第三时间与所述第二时间差，确定所述第四时间。
也就是说，在该实现方式中，第二时间差指的是BOSA停止发光与BOSA电源停止供电之间的时间差，此时BOSA电源可以和BOSA同时停止，也可以在BOSA停止发光一段时间后BOSA电源再停止供电，故而第二时间差可以大于或等于0。
在一种可能的实现方式中，所述第一时间与所述第二时间之间的时间差、和/或所述第三时间与所述第一时间之间的时间差、和/或所述第四时间与所述第三时间之间的时间差，在所述ONU的不同上行发送周期内是可调的。
也就是说，在该实现方式中，第一时间与第二时间之间的时间差、第三时间与第一时间之间的时间差、第四时间与所述第三时间之间的时间差，在ONU的不同上行发送周期内均可以是可调的，提高了电源控制的灵活性。
在一种可能的实现方式中，所述第一控制端与所述第二控制端位于所述ONU的中央处理器CPU内、且共用所述CPU的一个时钟。
也就是说，在该实现方式中，第一控制端和第二控制端采用相同的时间源，就是为了达到二者时钟同步，由于CPU内包括多个时间，第一控制端和第二控制端采用的时间源可以为CPU的一个时钟。
在一种可能的实现方式中，所述第一控制端与所述第二控制端位于所述ONU的PONMAC内、且共用所述PONMAC的内部时钟。
也就是说，在该实现方式中，若ONU内集成有PONMAC，比如：ONU的CPU集成有PONMAC，那么第一控制端和第二控制端可以位于该PONMAC内，二者使用的时间源为PONMAC的内部时钟，这样既保证了第一控制端和所述第二控制端采用相同的时间源保持时钟同步，还不增加ONU的硬件成本。
第二方面，本申请实施例提供了一种电源控制装置，其特征在于，所述装置用于控制光网络单元ONU，所述ONU包括光收发一体组件BOSA、为所述BOSA供电的BOSA电源、用于控制所述BOSA是否发光的第一控制端、以及用于控制所述BOSA电源是否供电的第二控制端，所述装置包括：

具体实施方式
为了使本申请实施例的目的、技术方案和优点更加清楚，下面将结合附图，对本申请实 施例中的技术方案进行描述。
在本申请实施例的描述中，“示例性的”、“例如”或者“举例来说”等词用于表示作例子、例证或说明。本申请实施例中被描述为“示例性的”、“例如”或者“举例来说”的任何实施例或设计方案不应被解释为比其它实施例或设计方案更优选或更具优势。确切而言，使用“示例性的”、“例如”或者“举例来说”等词旨在以具体方式呈现相关概念。
在本申请实施例的描述中，术语“和/或”，仅仅是一种描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，单独存在B，同时存在A和B这三种情况。另外，除非另有说明，术语“多个”的含义是指两个或两个以上。例如，多个系统是指两个或两个以上的系统，多个屏幕终端是指两个或两个以上的屏幕终端。
此外，术语“第一”、“第二”仅用于描述目的，而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征。由此，限定有“第一”、“第二”的特征可以明示或者隐含地包括一个或者更多个该特征。术语“包括”、“包含”、“具有”及它们的变形都意味着“包括但不限于”，除非是以其他方式另外特别强调。
图1是一种无源光网络(Passive Optical Networks，PON)的网络架构示意图；如图1所示，PON由光线路终端(Optical LineTerminal，OLT)、ONU或光网络终端(Optical network terminal，ONT)、以及光分配网络(Optical Distribution Network，ODN)组成。其中，ODN为点到多点结构，一个OLT经ODN中的分光器(Spliter)连接多个ONU。
图1中的PON可以包括以太网无源光网络(Ethernet Passive OpticalNetwork，EPON)、吉比特无源光网络(GigabitPassiveOpticalNetwork，GPON)等不同的组网方式。
需要说明的是，本申请涉及到的电源控制可以指的是对图1中的ONU进行电源控制，具体为通过动态控制ONU的BOSA电源的供电时间来达到降低ONU的BOSA功耗和工作温度的目的。
图2是一种节能模式示意图。在对图1中的ONU进行功耗管理时，可以通过OLT和ONU的协同，在ONU设备空闲时，使用周期性的开启上行发送和下行接收方式降低ONU设备功耗。该节能方式可以降低ONU设备的工作温度，从侧面降低ONU设备中BOSA的工作温度。如图2所示，该节能方式可以包括三种节能模式：打盹(Doze)模式、周期(Cyclic)模式以及唤醒(Watchful)模式。
其中，Doze模式是一直开启下行接收帧，周期性打开上行发送帧。
Cyclic模式是在上下行均周期性的关闭，仅仅在业务打开的时隙内接收局端唤醒。其中，局端是图1中的OLT，唤醒操作由OLT发送。比如ONU设备处于休眠状态，OLT需要首先唤醒ONU才能给ONU发送数据，否则发送数据会丢失。
Watchful模式是在Cyclic模式上周期性的短暂打开下行接收，但仅仅接收局端唤醒操作，不接受业务。相对于Cyclic模式，Watchful模式具有更好的时延性能。其中Cyclic和Doze模式可以通过Watchful模式调整下行唤醒脉冲的时间宽度来实现。
但是，图2所示的ONU功耗管理方案需要OLT和ONU进行配合，且实现复杂。同时，ONU必须处于空闲状态，对于ONU设备工作在低速低流量模式下比较有效，而对于需要频繁唤醒ONU的场景下并不能达到节省功耗的目的。
需要说明的是，本申请涉及到的电源控制可以指的是为图2中上行方向供电的BOSA电源进行动态控制。
图3是一种ONU的结构示意图；如图3所示，对于BOSA在板的ONU，通常包括中央处理器(Central Processing Unit，CPU)、光物理层(Physical Layer，PHY)、BOSA三个主要 部分。其中，CPU内部集成PON MAC(Medium Access Control，介质访问控制)，该PON MAC用于与光PHY之间交互，BOSA用于实现光电信号之间的相互转换。
其中，VCCT_ENABLE为电源使能信号，CPU控制电源模块为BOSA供电；
TXEN为发光使能信号，由CPU发送给光PHY，即CPU向光PHY发送TXEN信号后，光PHY收到TXEN信号后通过发光二极管(即LD+/LD-)驱动BOSA发光；
TXSD为发送光指示信号，由光PHY发送给CPU；
RXSD为接收光指示信号，由光PHY发送给CPU；
TX_DATA为发送数据通道；
RX_DATA为接收数据通道；
比如：在ONU需要对OLT发送数据时，由CPU将数据通过TX_DATA发送至光PHY，同时CPU通过TXEN信号控制光PHY发光，光PHY检测到TXEN信号有效后，将TX_DATA数据转换成需要传输的数据，通过LD+/LD-驱动BOSA对外发光。在光PHY开始驱动LD+/LD-对外发光时，光PHY对CPU发送TXSD信号。
又比如：在ONU接收到OLT发送的光信号后，BOSA将光信号转换成电信信号传输给光PHY，同时光PHY通过RXSD信号告知CPU收到光信号。
图3中的CPU通过VCCT_ENABLE信号打开或关闭电源模块。
图3中的电源模块与BOSA发送部分相连接，并专门为BOSA发送部分供电。在BOSA发光时电源模块必须打开给BOSA供电，否则发光异常。
需要说明的是，本申请涉及到的电源控制可以指的是对图3中专门为BOSA发送部分供电的电源模块进行动态控制。在本申请中，图3中专门为BOSA发送部分供电的电源模块统一定义为BOSA电源，其他实施例与此相同，不再赘述。
另外，图3中的电源模块可以通过金属—氧化物—半导体场效应晶体管(metal oxide semiconductor，MOS)管来实现。具体为：VCCT_ENABLE为低电平，打开MOS管，为BOSA发送部分供电。在单板启动系统初始化过程中，系统可以通过将VCCT_ENABLE拉低，从而打开MOS管给BOSA发送部分供电，这样无论BOSA是否需要发光，该电源模块一直为BOSA供电，造成了一定的功耗损失。比如：对于家庭终端产品实际用户的上行带宽通常较低，以具有千兆位功能的无源光网络(Gigabit-Capable Passive Optical Networks，GPON)为例上行带宽一般不超过30M，BOSA在发光的过程中，上行发送周期为125uS，而整个125uS的时隙中存在一定时间不发光。以GPON为例，上行带宽为30M时，125uS的时隙隙仅仅约3.69uS发光，并且，不发光时打开电源功耗约为发光时的30％，所以若无论BOSA是否需要发光，电源模块一直为BOSA的发送部分供电，从而造成了一定的功耗损失。
因此，为了解决在BOSA未发光时，打开电源模块所造成的功耗损失，本申请提供了一种电源控制方法、装置及设备，在周期性打开上行发送帧时，可以通过动态控制BOSA电源的供电时间来达到降低BOSA功耗和工作温度的目的。比如：通过将VCCT_ENABLE集成至PON MAC内部，实现VCCT_ENABLE信号与TXEN信号精准同步且时间差可调，可以适应不同外围电路器件，同时不依赖于OLT和ONT协调和ONU必须处于空闲态的限制。需要说明的是，虽然上文是以GPON进行举例说明，但本发明方案并不限于GPON场景下的ONU，其他PON网络的ONU也同样适用。
下面通过具体实施例进行说明。
图4是本申请实施例提供的一种电源控制过程的示意图。如图6所示，TXEN和VCCT_ENABLE均为PON MAC的控制信号，XPON时钟为PON MAC内部时钟，t1和t2为TXEN与 VCCT_ENABLE的时间差。TXEN低电平有效，表示发光，VCCT_ENABLE低有效，表示打开BOSA电源。具体实现过程包括：
第一、将控制BOSA电源的控制信号VCCT_ENABLE集成至PON MAC内部。VCCT_ENABLE脉冲的产生需要与TXEN采用相同的时钟源，即保证时钟同步。
第二、通过PON MAC内部的延时控制模块实现TXEN和VCCT_ENABLE信号时间差。其中t1为前导时间，t2为后导时间，前导时间t1用于提前打开VCCT_ENABLE信号，后导时间t2用于延迟关闭VCCT_ENABLE信号。
前导延时控制模块对前导延时向量进行解析，通过前导延时向量解析出需要延时的时钟信号脉冲个数，延时控制模块依据解析出来的脉冲个数锁定VCCT_ENABLE信号并输出低脉冲，即图4中a点，此时BOSA电源打开。同时，前导延时模块开始计时，计时结束后达到b点，此时TXEN信号拉低，开始指示光PHY发光。a点和b点时间差值为t1，完成前导时间延时。TXEN有效时间长度(b点和c点时间差值)由PON MAC内部的ONU分配发光时隙确定。
其中，图4中的VCCT_ENABLE信号属于开关信号，若用户不需要使用动态开关VCCT_ENABLE信号可以直接输出低电平或高电平。
值得说明的是，t1的取值范围可以为大于0。也就是说，由于在BOSA发光时电源模块必须打开给BOSA供电，否则发光异常，所以TXEN信号拉低之前必须先锁定VCCT_ENABLE信号并输出低脉冲。
第三，实现后导延时时间控制。首先后导延时控制模块对后导延时向量进行解析，通过后导延时向量解析出需要延时的时钟信号脉冲个数。当前时间达到c点，即TXEN无效时，后导延时模块开始计数，计数结束时达到d点，c、d两点之间的时间差为后导时间t2。到达d点时VCCT_ENABLE拉高，此时关闭BOSA的发送电源。
值得说明的是，t1的取值范围可以为大于或等于0。
第四，针对每个上行发送周期，即上行发送周期为125us，重复执行上述前导延时控制和后导延时控制。
值得说明的是，本申请中的上行发送周期为125us，针对每个上行发送周期，均可以通过动态控制BOSA电源来达到降低BOSA功耗和工作温度的目的。其中，TXEN有效时间长度可以根据上行数据量的大小来调整，但其最大值小于125us。t1和t2的具体大小可以预先配置。
以300Mbps(下行)/50Mbps(上行)为例：
在上行带宽为50Mbps时，TXEN信号有效约为5.7uS。按照前导时间t1和后导时间t2各位1us计算，实际BOSA的供电电源约为7.7uS，相对于整个125us的周期内一直供电的供电时间占比为7.7/125＝6.16％。
以GPON BOSA方案为例，发光时电流约为100mA，不发光时电流约为30mA。本申请采用的电源控制方案节省功耗约为3.3V×30mA×(100％-6.16％)＝0.092W，避免温度升高0.092W×73.9℃/W＝6.79度。
按照电子元器件温度每升高10度寿命降低的一半的规则，本申请采用的电源控制方案能避免BOSA温度非必要的升高，有效提升高温场景下BOSA使用寿命。
此外，该方案不额外增加ONU的硬件成本。
图5是本申请实施例提供的一种电源控制方法的流程示意图；该方法可以用于ONU，该ONU包括BOSA(如图3中的BOSA)、为BOSA供电的BOSA电源(如图3中的电源模块)、用于控制BOSA是否发光的第一控制端(如图3中的TXEN的控制端)、以及用于控制所述BOSA电源是否供电的第二控制端(如图3中的VCCT_ENABLE的控制端)；其中，第一控制端和第二控 制端可以位于图3中CPU内，且共用该CPU的一个时钟；也可以位于PON MAC内，且共用该PON MAC的内部时钟，该PON MAC集成在图3中CPU内。如图5所示，该电源控制方法可以包括以下步骤：
S501、针对ONU的至少一个上行发送周期，基于上行发送的开启时间确定第一控制信号生效的第一时间，第一控制信号用于第一控制端控制BOSA发光。
具体地，为了降低ONU设备功耗，ONU设备可以周期性地开启上行发送，每次开启上行发送的时间为第一控制信号生效的第一时间。
第一控制信号可以为图4中的TXEN信号，低电平有效，即第一控制端向ONU中的光PHY(如图3中的光PHY)发送第一控制信号，光PHY根据接收到的第一控制信号驱动BOSA(如图3中的BOSA)发光。
第一时间可以为图4中的b点，即控制BOSA(如图3中的BOSA)开始发光的时间。
在基于上行发送的开启时间确定第一控制信号生效的第一时间时，可以根据ONU的工作模式和第一时钟信号，确定第一时间；其中，ONU的工作模式包括第一控制端周期性地控制BOSA发光，第一时钟信号为第一控制端和第二控制端共用的时钟信号。
其中，ONU的工作模式可以参见图2所示的打盹(Doze)模式、周期(Cyclic)模式以及唤醒(Watchful)模式，在这些模式中上行方向均是周期性地控制BOSA发光。
若第一控制端和第二控制端位于图3中CPU内，且共用该CPU的一个时钟，则该第一时钟信号为该CPU的时钟信号；若第一控制端和第二控制端位于PONMAC内，且共用该PONMAC的内部时钟，则该第一时钟信号为该PONMAC的时钟信号(如图4中的XPON时钟信号)。其中，PONMAC可以集成在图3中CPU内。
S502、基于第一时间确定第二控制信号生效的第二时间，第二时间早于第一时间，第二控制信号用于第二控制端控制BOSA电源供电。
具体地，为了进一步降低ONU设备功耗，ONU设备可以周期性地开启BOSA电源供电，每次开启BOSA电源供电为第二控制信号生效的第二时间。并且，为了保证BOSA正常工作，需要在每次开启上行发送之前开启BOSA电源供电，即第二时间早于第一时间。
第二时间可以为图4中的a点，即提前打开BOSA电源的时间。
第二控制信号可以为图4中的VCCT_ENABLE信号，低电平有效，即第二控制端向BOSA电源(如图3中的电源模块)发送第二控制信号，BOSA电源根据接收到的第二控制信号开始为BOSA(如图3中的BOSA)供电。
在基于第一时间确定第二控制信号生效的第二时间时，可以获取第一时间差，第一时间差为第一时间与第二时间之间的设定差值；基于第一时间与第一时间差，确定第二时间。
其中，第一时间差可以为图4中的t1，这样可以通过第一时间与第一时间差来确定的第二时间，即图4中的a点。
第一时间差可以大于0，其具体大小在ONU的不同上行发送周期内是可调的，即图4中各个t1的具体大小是可调的，各个t1可以均相等，也可以均不等，还可以部分t1相等，部分t1不等。
S503、在第二时间使第二控制信号生效。
具体地，控制BOSA开始发光的时间之前，可以提前打开BOSA电源，这样避免了BOSA出现发光常。
由上述实施例可见，针对ONU的每个上行发送周期，可以在BOSA开始发光之前提前打开BOSA电源，即基于第一时间确定第二时间，且第二时间早于第一时间，从而在保证了BOSA 正常工作的前提下，降低了BOSA功耗，降低了BOSA工作温度，提高了BOSA使用寿命。
图6是本申请实施例提供的一种电源控制方法的流程示意图；该方法建立在图5所示方法的基础上，如图6所示，该电源控制方法还可以包括以下步骤：
S601、基于第一时间确定第三控制信号生效的第三时间，第三控制信号用于第一控制端控制BOSA停止发光。
具体地，第一时间可以为图4中的b点，即控制BOSA(如图3中的BOSA)开始发光的时间。第三时间可以为图4中的c点，即控制BOSA(如图3中的BOSA)停止发光的时间。其中，第三时间与第一时间之间的时间差的具体大小在ONU的不同上行发送周期内是可调的，比如：根据上行数据量的大小来调整第三时间与第一时间之间的时间差，若上行数据量较小，可以调小第三时间与第一时间之间的时间差；若上行数据量较大，可以调大第三时间与第一时间之间的时间差。
第三控制信号可以为图4中的TXEN信号，高电平有效，即第一控制端向ONU中的光PHY(如图3中的光PHY)发送第三控制信号，光PHY根据接收到的第三控制信号驱动BOSA(如图3中的BOSA)停止发光。
S602、基于第三时间确定第四控制信号生效的第四时间，第四时间晚于第三时间，第四控制信号用于第二控制端控制BOSA电源停止供电。
具体地，第四时间可以为图4中的d点，即关闭BOSA电源的时间。
第四控制信号可以为图4中的VCCT_ENABLE信号，高电平有效，即第二控制端向BOSA电源(如图3中的电源模块)发送第四控制信号，BOSA电源根据接收到的第四控制信号停止为BOSA(如图3中的BOSA)供电。
在基于第三时间确定第四控制信号生效的第四时间时，可以获取第二时间差，第二时间差为第四时间与第三时间之间的设定差值；基于第三时间与第二时间差，确定第四时间。
其中，第二时间差可以为图4中的t2，这样可以通过第一时间与第一时间差来确定的第二时间，即图4中的d点。
第二时间差可以大于0，也可以等于0。在大于0时，其具体大小在ONU的不同上行发送周期内是可调的，即图4中各个t2的具体大小是可调的，各个t2可以均相等，也可以均不等，还可以部分t2相等，部分t2不等。
S603、在第四时间使第四控制信号生效。
具体地，在控制BOSA停止发光的时间之后，可以关闭BOSA电源，这样避免了在BOSA未发光时，BOSA电源打开电源模块所造成的功耗损失。
由上述实施例可见，针对ONU的每个上行发送周期，除了可以在BOSA开始发光之前提前打开BOSA电源之外，还可以在BOSA停止发光之后关闭BOSA电源，即基于第三时间确定第四时间，且第四时间晚于第三时间，从而进一步降低了BOSA功耗，降低了BOSA工作温度，提高了BOSA使用寿命。
