Description

功耗控制方法与摄像装置
本申请要求于2018年2月8日提交中国专利局、申请号为201810127984.8、发明名称为“功耗控制方法与摄像装置”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
本发明涉及自动控制领域，更具体的说，涉及功耗控制方法与摄像装置。
背景技术
智能猫眼是一种替代传统猫眼的家居安防产品，其实质为一种网络摄像机。为了满足业主的安全需求，网络摄像机需要每天24小时持续工作，功耗较高，尤其是采用电池供电方式的网络摄像机，其续航能力较差，进而影响用户体验。
网络摄像机(IPC，IP Camera)通常包括IPC主模块、摄像头、红外补光灯、功耗控制模块、人体红外感应(PIR)模块和WIFI模块等，其中，IPC主模块及相关外围设备为主要耗电部分。目前常采用的功耗控制方案是利用功耗控制模块将IPC主模块、摄像头与红外补光灯默认设置为休眠状态或断电状态，仅保持功耗控制模块、PIR模块和WIFI模块的正常工作，当PIR模块感应到有人出现、用户操作网络摄像机或WiFi模块接收到用户发起的远程唤醒请求时，功耗控制模块才会控制IPC主模块、摄像模块与红外补光模块进入正常工作模式，从而在一定程度上降低了网络摄像机的功耗水平。但是，当IPC主模块开始正常工作后，无论是否需要使用摄像头，摄像头都会一直保持在工作状态，IPC主模块的视频编码单元也一直处于工作状态，红外补光等也会在光线不足时一直保持在工作状态，直到功耗控制模块控制IPC主模块再次进入断电状态或休眠状态为止。由此可见，现有网络摄像机的功耗控制方案，仍会产生大量不必要的功率损耗，其功耗控制效果较差。
因此，目前迫切需要一种能够更加有效地降低摄像机功耗水平的技术方案。

具体实施方式
下面将参照附图更详细地描述本公开的示例性实施例。虽然附图中显示了本公开的示例性实施例，然而应当理解，可以以各种形式实现本公开而不应被这里阐述的实施例所限制。相反，提供这些实施例是为了能够更透彻地理解本公开，并且能够将本公开的范围完整的传达给本领域的技术人员。
本发明提供的功耗控制方法，应用于摄像装置，所述摄像装置包括摄像单元。所述摄像单元在所述摄像装置启动后处于关闭状态、低功耗状态或休眠状态等等，该关闭状态、低功耗状态与休眠状态具体可以是用户预设的或系统预置的。所述关闭状态可以具体是指摄像单元处于断电状态，所述低功耗状态是 指摄像单元维持最基本功能或采用最低采样速率的工作状态，所述休眠状态是指摄像单元暂停工作的状态。本发明的功耗控制方法，采用了最小模块化的控制方式，以对摄像装置中单元模块分别进行控制。本发明的摄像装置可以是智能猫眼设备，也可以是室内、外网络摄像机，还可以是其他类型的摄像装置。
请参阅图1，图1为本申请实施例提供的功耗控制方法的一种流程图。
如图1所示，所述方法包括：
S101：获取所述摄像装置的工作场景信息；所述工作场景信息包括所述摄像装置正在启动或正在执行的任务信息。
根据摄像装置正在启动或正在执行的任务能够准确确定出摄像单元是否需要被使用，所以需要先对所述摄像装置正在启动或正在执行的任务的信息进行获取。其中，任务可以包括具体的指令，也可以包括具体的功能。例如，根据接收到的任务请求指令，获取任务请求指令中携带的任务信息(即为正在启动的任务信息)，或者，监视正在运行的任务进程，根据任务进程获取与任务进程相对应的任务信息(即为正在执行的任务信息)。
S102：根据所述工作场景信息，获取所述摄像单元的使用需求信息；所述摄像单元的使用需求信息用于表征所述摄像单元是否需要被使用。
所述工作场景信息与所述摄像单元的使用需求信息之间具有对应关系。例如，摄像装置的历史录像上传任务、与服务器之间的信息同步任务、在线升级任务等，均与不需要使用到摄像单元的使用需求信息相对应；而摄像装置的摄像任务、实时视频显示任务等，均与需要使用到摄像单元的使用需求信息相对应。
在实际应用中，可以建立需求关系表，在需求关系表中记录至少一条工作场景信息与摄像单元的使用需求信息之间的对应关系。
一示例中，需求关系表是可以根据实际需要进行配置的，例如，增加、删除、修改需求关系表中工作场景信息与摄像单元的使用需求信息之间对应关系。
因此，根据所述摄像装置正在启动或正在执行的任务，能够准确地确定出所述摄像单元是否需要被使用，进而获取到用于表征所述摄像单元是否需要被使用的使用需求信息。
S103：响应于表征所述摄像单元需要被使用的使用需求信息，控制所述摄像单元启动。
在摄像装置上电并启动后，当用户仅需要摄像装置执行历史录像上传、信息同步等任务时，显然是不需要使用到摄像单元的，若摄像单元在摄像装置启动后即刻启动或一直处于工作状态，必然会造成不必要的功耗损失，所以本实施例中的摄像单元在摄像装置启动后默认是处于关闭状态的，只有在需要被使用时才会予以启动，从而避免了摄像单元在不需要被使用时处于工作状态而导致的功耗损失。
本实施例提供的功耗控制方法，应用于摄像装置，所述摄像装置中的摄像单元在摄像装置启动后默认处于关闭状态，获取摄像装置的工作场景信息，根据摄像装置的工作场景信息确定摄像单元是否需要被使用，当确定摄像单元需要被使用时，再控制所述摄像单元启动，当摄像单元不需要被使用时，则会保持关闭状态不变，从而避免了摄像单元在不需要被使用时处于工作状态而导致的功耗损失，有效降低了摄像装置的功耗水平，提高了功耗控制效果。
请参阅图2，图2为本申请实施例提供的功耗控制方法的另一种流程图。
如图2所示，所述方法包括：
S201：获取所述摄像装置的工作场景信息；所述工作场景信息包括所述摄像装置正在启动或正在执行的任务信息。
S202：根据所述工作场景信息，获取所述摄像单元的使用需求信息；所述摄像单元的使用需求信息用于表征所述摄像单元是否需要被使用。
S203：响应于表征所述摄像单元需要被使用的使用需求信息，控制所述摄像单元启动。
其中，步骤S201-S203与前述实施例中的步骤S101-S103相类似，具体可参见前述实施例，在此不再赘述。
S204：在所述摄像单元启动之后，获取所述摄像单元的使用状态信息。
所述使用状态信息用于表征所述摄像单元是否使用完毕。
在一示例中，仍可根据摄像装置的工作场景信息，获取摄像单元的使用状态信息。例如，在摄像单元启动之后，当没有任何正在启动或正在执行的任务需要使用摄像单元时，或者，没有任何任务正在启动或正在执行时，表示摄像 单元已经使用完毕，从而获得用于表征摄像单元使用完毕的使用状态信息；当有任何正在启动或正在执行的任务仍在使用摄像单元时，表示摄像单元未使用完毕，从而获得用于表征摄像单元未使用完毕的使用状态信息。
S205：当所述使用状态信息表征所述摄像单元使用完毕时，控制所述摄像单元关闭。
当摄像单元使用完毕时，及时控制所述摄像单元关闭，能够避免在摄像单元使用完毕后一直处于工作状态而造成不必要的功耗损失，从而在最大程度上保证摄像单元的有效使用，减少摄像装置的功耗损失。
本实施例提供的功耗控制方法，应用于摄像装置，在摄像单元启动之后，对摄像单元的使用状态信息进行获取，当摄像单元使用完毕时，及时关闭摄像单元，从而进一步提高了摄像单元功耗控制的准确性，进一步降低了摄像装置的功耗损失，提高了功耗控制效果。
请参阅图3，图3为本申请实施例提供的功耗控制方法的又一种流程图。
本实施例中摄像装置还包括补光单元；所述补光单元在所述摄像装置启动后也处于关闭状态。
如图3所示，所述方法包括：
S301：获取所述摄像装置的工作场景信息；所述工作场景信息包括所述摄像装置正在启动或正在执行的任务信息。
S302：根据所述工作场景信息，获取所述摄像单元的使用需求信息；所述摄像单元的使用需求信息用于表征所述摄像单元是否需要被使用。
该步骤S301-S302与前述实施例中的步骤S101-S102或S201-202相类似，具体可参见前述实施例，在此不再赘述。
S303：当所述摄像单元的使用需求信息表征所述摄像单元需要被使用时，获取环境光照强度。
当摄像单元的使用需求信息表征所述摄像单元需要被使用时，表明摄像单元会在当前环境下进行摄像，环境的光照强度会严重影响摄像效果，因此，需要在确定使用摄像单元后，获取环境光照强度，以确定是否需要开启补光单元进行补光。
当所述摄像单元的使用需求信息表征所述摄像单元不需要被使用时，摄像单元保持在关闭状态不予启动，也就不需要控制补光单元启动，进而也就不需要获取环境光照强度。
在一示例中，可以通过光敏电阻来检测环境光照强度，进而获取光敏电阻检测到的环境光照强度。当然，也可以采用其他类型的光强检测单元来检测环境光照强度，在此不做具体限定。
S304：当所述环境光照强度符合预设补光条件时，控制所述补光单元启动。
在传统方案中，摄像单元是随着摄像装置的启动而启动的，所以，只要环境光线不足时，便会启动补光单元进行补光，以保证摄像单元的摄像效果，而本发明的摄像单元是根据摄像装置的工作场景信息来控制的，若仅根据环境光照强度来控制补光单元的开启与关闭，必然会出现在不需要使用摄像单元工作时补光单元被开启的情况，进而导致补光单元出现不必要的功耗损失。
所以，本实施例中补光单元在摄像装置启动后默认也是处于关闭状态的，而且，必须当摄像单元需要被使用且环境光照强度符合预设补光条件时，才会控制补光单元启动，而并不是在摄像装置启动后直接启动，也并不是仅仅在环境光照强度符合预设补光条件时启动，从而避免了在不需要使用摄像单元时补光单元的不必要启动，进而避免了补光单元不必要的启动所造成的不必要的功耗损失。
当摄像单元不需要被使用或环境光照强度不符合预设补光条件时，补光单元保持在原来的关闭状态。
在一示例中，预设补光条件可以是环境光照强度小于光强阈值，也可以是环境光照强度不大于光强阈值，还可以是其他用户预设的补光条件(如，判断是否为夜间)。
其中，补光单元可以是红外补光单元，也可以是其他类型的补光单元，在此不做具体限定。
S305：响应于表征所述摄像单元需要被使用的使用需求信息，控制所述摄像单元启动。
其中，该步骤S305可在步骤S302之后执行，也可以在步骤S304之后执行，还可以在确定所述环境光照强度不符合预设补光条件时予以执行。
该步骤S305的具体内容与前述实施例中的步骤S103或S203相类似，具体可参见前述实施例，在此不再赘述。
S306：在所述补光单元启动之后，获取所述摄像单元的使用状态信息。
所述使用状态信息用于表征所述摄像单元是否使用完毕。
S307：当所述使用状态信息表征所述摄像单元使用完毕时，控制所述补光单元关闭。
当摄像单元使用完毕时，及时控制所述补光单元关闭，能够避免在补光单元使用完毕后一直处于工作状态而造成不必要的功耗损失，从而在最大程度上保证补光单元的有效使用，减少摄像装置的功耗损失。
本实施例在步骤S305之后还可以包括前述实施例中的步骤S204-S205，进而当摄像单元使用完毕时，控制所述补光单元与摄像单元及时关闭，能够从最大程度上保证补光单元与摄像单元的有效使用，避免不必要的功耗损失，降低摄像装置的整体功耗水平。
本实施例提供的功耗控制方法，当确定摄像单元需要被使用时，再确定所述环境光照强度是否符合预设补光条件，当所述环境光照强度符合预设补光条件时，控制所述补光单元启动，保证了补光单元在摄像单元需要被使用且环境光照强度符合预设补光条件时才在关闭状态下启动，提高了补光单元启动控制的准确性，进而提高了功耗控制的准确性；并且，在补光单元启动后，对摄像单元的使用状态信息进行获取，当摄像单元使用完毕时，及时关闭补光单元，进一步保证了补光单元的准确控制，避免了不必要的功耗损失，提高了功耗控制效果。
请参阅图4，图4为本申请实施例提供的功耗控制方法的再一种流程图。
如图4所示，所述方法包括：
S101：获取所述摄像装置的工作场景信息；述工作场景信息包括所述摄像装置正在启动或正在执行的任务信息。
S402：根据所述工作场景信息，获取所述摄像单元的使用需求信息；所述摄像单元的使用需求信息用于表征所述摄像单元是否需要被使用。
S403：当所述摄像单元的使用需求信息表征所述摄像单元需要被使用时，获取环境光照强度。
S404：当所述环境光照强度符合预设补光条件时，控制所述补光单元启动。
S405：响应于表征所述摄像单元需要被使用的使用需求信息，控制所述摄像单元启动。
其中，步骤S401-S405与前述实施例中的步骤S301-S305相类似，具体可参见前述实施例，在此不再赘述。
S406：在所述摄像单元启动之后，再次获取环境光照强度。
在摄像单元启动之后，环境光照强度可能会发生变化，若一直开启着补光单元，必然会导致不必要的功耗损失，所以，在摄像单元启动之后，可以再次获取环境光照强度。具体地，再次获取环境光照强度时，可以采取周期性的获取方式，也可以采取实时获取方式。然而，相对于实时获取方式，显然周期性获取方式的功耗更低。
S407：根据再次获取的环境光照强度，控制所述补光单元启动或关闭。
具体地，当补光单元已被开启且再次获取的环境光照强度不符合预设补光条件时，控制补光单元关闭，从而在摄像单元的使用过程中，从最大程度上保证补光单元的有效使用，避免了不必要的功耗损失。
相应地，当补光单元未被开启且再次获取的环境光照强度符合预设补光条件时，控制补光单元启动，以保证摄像效果。当补光单元未被开启且再次获取的环境光照强度不符合预设补光条件时，或者，当补光单元已被开启且再次获取的环境光照强度符合预设补光条件时，保持补光单元的现有状态不变。
本实施例还可以在步骤S405后包括前述实施例中的步骤S204-S205与S306-S307，具体内容可参见前述实施例。
本实施例提供的功耗控制方法，在摄像单元启动之后，根据再次获取的环境光照强度，控制所述补光单元启动或关闭，进而在摄像单元的使用过程中，从最大程度上保证补光单元的有效使用，进一步避免了补光单元在摄像单元使用过程中可能导致的不必要的功耗损失，提高了功耗控制效果。
在本申请的其他实施例中，摄像装置还包括视频编码单元，视频编码单元可以包括硬件编码器和/或软件编码器。在所述摄像单元启动之后，所述功耗控制方法还可以包括：
A1)、根据所述工作场景信息，获取视频编码单元的使用需求信息；所述 视频编码单元的使用需求信息用于表征所述视频编码单元是否需要被启动；
A2)、响应于表征所述视频编码单元需要被使用的启动需求信息，控制所述视频编码单元启动。

B2)、当所述视频编码单元的使用状态信息表征所述视频编码单元使用完毕时，控制所述视频编码单元关闭。
在该示例中，在摄像单元启动后，还根据摄像装置的工作场景信息进一步判断是否需要启动视频编码单元，进一步实现了最小模块化的低功耗控制。
在实际应用中，可以再另外建立一个需求关系表，用于记录至少一条工作场景信息与视频编码单元的使用需求信息之间的对应关系。对于该需求关系表同样可以根据实际需要进行配置，例如，增加、删除、修改该需求关系表中工作场景信息与视频编码单元的使用需求信息之间对应关系。
一示例中，所述摄像装置还包括无线传输单元，所述无线传输单元具有低功耗工作模式；所述功耗控制方法还包括：
C1)、所述无线传输单元在所述低功耗工作模式下，进入休眠状态；
C2)、所述无线传输单元在进入所述休眠状态之后，定时从所述休眠状态切换至工作状态以获取远程数据；

其中，定时方式可采用配置休眠周期的方式来实现，例如，配置休眠800毫秒后自动切换至工作状态，并与路由器交换完数据后，再次切换至休眠状态，如此循环。
一示例中，所述远程数据具体为远程唤醒指令。所述无线传输单元，具体用于获取所述远程唤醒指令。其中，远程唤醒指令可以是由用户通过客户端发出并经由唤醒服务器转发至无线传输单元的。
其中，无线传输单元可以与唤醒服务器保持一个网络长连接，等待接收由唤醒服务器转发来的远程唤醒指令。
另一示例中，所述功耗控制方法除了包括以上实施例的步骤外，还可以包括：
在摄像内容的录制过程中，将已录制内容实时传送至云录像服务器。
摄像内容的录制与录制内容的上传，都需要摄像装置的主控单元来执行，传统的技术方案，摄像内容的录制与录制内容的上传是分别独立执行的，也就是说，主控单元需要分别花费时间去执行摄像内容的录制与录制内容的上传，使得主控单元长时间处于工作状态，功耗损失较大。
本实施例提供的功耗控制方法，通过在摄像内容的录制过程中，将已录制内容实时传送至云录像服务器，实现了摄像内容的边录边传过程，两者几乎是同时进行的，大幅缩短了摄像装置中主控单元的工作时长，降低了主控单元的功耗损失。在实际应用中，本实施例提供的边录边传的工作方式相比传统的先录后传的工作方式，能将主控单元的工作时长缩短将近一半，提高了功耗控制效果。

本实施例提供的摄像装置，当确定摄像单元需要被使用时，再确定所述环境光照强度是否符合预设补光条件，当所述环境光照强度符合预设补光条件时，控制所述补光单元启动，保证了补光单元在摄像单元需要被使用且环境光照强度符合预设补光条件时才在关闭状态下启动，提高了补光单元启动控制的准确性，进而提高了功耗控制的准确性；在摄像单元启动之后，根据再次获取的环境光照强度，控制所述补光单元启动或关闭；并对摄像单元的使用状态信息进行获取，当摄像单元使用完毕时，及时关闭摄像单元；若在之前也开启了补光单元，则在摄像单元使用完毕时，同样及时关闭补光单元；进而保证了摄像单元与补光单元的准确控制，避免了摄像单元与补光单元可能导致的不必要的功耗损失，提高了功耗控制效果。

例如，当光强不符合预设补光条件时，切换到红外截止滤光片，过滤掉红外光，只让可见光进入；当光强符合预设补光条件时，切换到全透光滤光片，让红外光进入摄像头传感器。所述IR-CUT单元可与红外补光单元相互配合使用。
