PoE技术的使用越来越广泛，支持PoE功能的交换机越来越普遍，如思科、华为的交换机。近些年，特别在欧美市场上，支持PoE功能且无电池的平板电脑、笔记本电脑或一体机等电子产品也越来越多。
PoE技术的主要应用场景有两种：
1)没有铺设电力线，无法使用电源适配器，只能采用PoE技术给平板电脑、笔记本电脑或一体机等电子产品供电；
2)停电时，自动切换到PoE供电模式，采用PoE技术给平板电脑、笔记本电脑或一体机等电子产品供电。
但在采用PoE技术供电时，若受电设备的功耗超过供电设备的供电限制时，受电设备特别是无电池的设备将无法正常工作，无法正常工作的情况包括但不限于：
1)无法正常开机；
2)自动关机；
3)循环地重启。

图1示出根据本申请示例实施例的一种设备功耗管理系统的示意图。
如图1所示，设备功耗管理系统包括供电设备101、受电设备102、通信链路103、供电模式监测模块104、PoE功耗估算模块105、PoE省电策略配置模块106和交互界面107。
应该理解，图1中的设备和模块的数目仅仅是示意性的。根据现实需要，可以具有任意数目的设备和模块。
供电设备101包括支持PoE功能的以太网交换机、路由器、集线器或者其他网络交换设备，以及电源适配器。
受电设备102包括支持PoE功能的平板电脑、笔记本电脑或一体机等电子设备。
根据一些实施例，支持PoE功能的电子设备包括未配置电池的电子设备。
通信链路103用以在供电设备101和受电设备102之间提供网络通信链路的介质，可以包括各种连接类型，例如光纤电缆、无线通信链路等。
根据一些实施例，受电设备102通过LLDP协议经由通信链路103向供电设备101发送分配功率的申请，并获取由供电设备101返回的受电设备102分配到的功率信息。
一般地，受电设备102分配到的功率由供电设备101根据与供电设备参数相对应的PoE规范中的功耗限制进行分配。
例如，若供电设备101支持PoE(IEEE802.3af)标准，则供电设备101可分配的功率为12.95W。
供电模式监测模块104设置供电模式判断信号，根据判断信号的电平高或低，判断供电设备101的供电模式。
根据一些实施例，供电模式判断信号包括AC IO信号和PoE IO信号，其中，
当AC IO信号和PoE IO信号均为高电平时，由电源适配器供电；
当AC IO信号为高电平并且PoE IO信号为低电平时，由电源适配器供电；
当AC IO信号为低电平并且PoE IO信号为高电平时，采用PoE模式供电。
一般地，供电模式判断信号AC IO信号和PoE IO信号不会出现同为低电平的情况。
PoE功耗估算模块105用于获取PoE模式下受电设备102的功耗限 制以及计算第一可用功耗，并通过由PoE省电策略模块106获取PoE省电策略的调整目标并估算调整后的PoE省电策略中设备功能的功耗数据和第二可用功耗。
根据一些实施例，PoE功耗估算模块105通过包括受电设备102在内的多个受电设备获取当前已使用的功耗，结合当前PoE规范的功耗限制，计算第一可用功耗。
进一步地，PoE功耗估算模块105根据第一可用功耗以及由PoE省电策略模块106发送来的用户设置的调整目标，估算经过性能调整(如LCD背光亮度的调节)和/或功能的开启或关闭(如蓝牙功能的开启或关闭)后，受电设备102设备功能的功耗数据及剩余的第二可用功耗。
PoE省电策略配置模块106用于根据第一可用功耗、第二可用功耗，结合受电设备102设备功能的功耗数据，在交互界面107进行显示，用户可通过交互界面107进行操作并配置受电设备的设备功能调整目标，PoE省电策略配置模块106通过交互界面107接收用户的指令，并将设备功能的调整目标发送至PoE功耗估算模块105。
根据一些实施例，PoE功耗估算模块105获取受电设备102的性能参数，并根据经验数据，估算受电设备102在PoE省电策略配置模块106中的设备功能的功耗数据。
例如，受电设备102的性能参数包括液晶显示器(LCD)的背光亮度、网络连接情况、USB接口使用情况及扬声器音量等，其中，若LCD背光亮度为30％，则根据经验数据估算出LCD背光功耗为0.90W。
用户可根据自身使用习惯在交互界面107对受电设备的设备功能进行关闭或开启，PoE省电策略配置模块106响应用户的操作，反馈数据至PoE功耗估算模块105及受电设备102，防止开启过多功能导致系统功耗超过PoE限制。
根据一些实施例，PoE省电策略配置模块106中管控的受电设备的功能，无法通过其他系统或模块开启或关闭。
图2示出根据本申请示例实施例的一种设备功耗管理方法的流程图。
如图2所示，在S201，对供电设备的供电模式进行实时监测，在供电设备的供电模式为PoE模式情况下，获取受电设备的功耗限制。
根据一些实施例，首先通过供电模式监测模块判断供电设备的供电模式，若采用PoE模式供电，则根据供电设备所支持的PoE规范，通过LLDP协议获取受电设备的功耗限制。
在S203，接收用户的调整操作指令，并根据调整操作指令设置调整目标。
根据一些实施例，用户通过PoE省电策略配置模块获取受电设备的可用功耗和实时功耗数据，并根据自身需求进行操作，设置受电设备的设备功能调整目标。
进一步地，PoE省电策略配置模块根据用户的操作指令，将设备功能调整目标传输至PoE功耗估算模块。
S205，根据受电设备的功耗限制及调整目标，估算受电设备的可用功耗和实时功耗数据。
根据一些实施例，PoE功耗估算模块通过计算PoE规范下供电设备可提供的功率与受电设备获取到的功率的差值获取第一可用功耗。
进一步地，根据第一可用功耗和PoE省电策略模块中受电设备的设备功能的设置，估算第二可用功耗。
一般地，PoE省电策略模块和PoE功耗估算模块在供电模式为PoE模式时启用，在非PoE模式(如电源适配器)时停用。
PoE省电策略模块中的受电设备的设备功能，包括但不限于：LCD背光亮度的调节、移动网络的启用/禁用、Wi-Fi的启用/禁用、蓝牙的启用/禁用、USB的启用/禁用、扬声器音量的调节、外部显示器的启用/禁用和处理器省电模式的启用等。
一般地，因受电设备功耗大而在通过LLDP协议无法分配到特定功耗时，处理器省电模式默认开启。
理论上，当供电设备只支持PoE(IEEE802.3af)标准，受电设备可分配到的最大功耗为12.95W的情况下，才会启用处理器省电模式。
根据受电设备的设备功能参数和经验数据，PoE功耗估算模块估算出受电设备的设备功能的实时功耗数据。
在S207，基于可用功耗和实时功耗数据，对受电设备的设备功能进行调整，并显示调整后的可用功耗和实时功耗数据。
根据一些实施例，可使用默认功耗配置管理和调整受电设备的设备功能，默认功耗配置根据受电设备的功耗限制，最大限度启用受电设备的功能。
一般地，不同的受电设备的产品规格和功耗情况不相同，结合不同PoE规范下可分配的功耗不相同以及不同的用户需求，所采用的默认功耗配置也不相同。
例如，Elo i-series 4.0，10寸设备，在PoE+(IEEE 802.3at)标准下的默认配置为：
LCD背光亮度：80％；
雷电USB：关闭；
USB 3.0：关闭；
USB 2.0：关闭；
蓝牙：开启；
Wi-Fi：关闭；
扬声器音量：50％；
外部显示器：关闭；
处理器省电模式：关闭。
又例如，Elo i-series 4.0，22寸设备，在PoE+(IEEE 802.3at)标准下的默认配置为：
LCD背光亮度：70％；
雷电USB：关闭；
USB 3.0：关闭；
USB 2.0：关闭；
蓝牙：开启；
Wi-Fi：关闭；
扬声器音量：0；
外部显示器：关闭；
处理器省电模式：关闭。
根据一些实施例，用户可根据自身使用习惯，及在供电设备支持的PoE规范下可用功耗和PoE省电策略模块中设备功能的实时功耗数据， 对默认功耗配置中的设备功能进行调整，包括对部分功能进行关闭或开启。
进而，在受电设备的设备功能调整完成后，通过PoE省电策略模块向用户展示调整后的可用功率和调整后的设备功能的实时功耗数据。
图3示出根据本申请示例实施例的启用PoE省电策略的流程图。
如图3所示，启动受电设备，首先通过供电模式监测模块检测供电设备是否通过PoE模式供电，若检测结果为PoE模式供电，则启动PoE省电策略。
一般地，PoE省电策略可按照受电设备设备功能中的功耗数据由高到低的顺序进行调整，或根据用户的实际需求对设备功能进行调整。
如图3所示的实施例，启动PoE省电策略，因LCD背光亮度的功耗最大，先进行LCD背光亮度调节。
LCD背光亮度调节完成后，根据PoE省电策略依次判断启用或禁用雷电USB通路、USB3.0通路和USB2.0通路，进行USB接口的功能配置。
USB接口配置完成后进行网络连接情况的配置，包括移动网络和Wi-Fi连接的启用或禁用。
其中，若禁用移动网络，则将受电设备切换至飞行模式。
进一步地，进入蓝牙功能是否启用的判断过程。
进而，根据供电设备支持的PoE规范判断是否切换处理器至省电模式。
最后，完成扬声器音量的调节，PoE省电策略启动完成。
图4示出根据本申请示例实施例的PoE省电策略的交互示意图。
如图4所示，用户通过PoE省电策略的交互子模块界面配置受电设备的设备功能。
在PoE+(IEEE 802.3at)标准下，供电设备可提供的功耗为25.5W，其中，已使用13.00W，可用功耗为12.50W。
如图4所示的受电设备默认设置及估算的功耗数据为：
LCD背光亮度：30％，功耗：0.90W；
扬声器音量：25％，功耗：0.25W；
移动网络：关闭，功耗：3.25W；
Wi-Fi：关闭，功耗：2.80W；
蓝牙：关闭，1.00W；
雷电USB：关闭，功耗：5.60W；
USB 3.0：关闭，功耗：4.50W；
USB 2.0：关闭，功耗：2.00W；
外部显示器：关闭，功耗：1.00W；
处理器省电模式：关闭，功耗：1.20W。
用户可选择相应的功能进行调整，如关闭或开启，PoE省电策略模块响应于用户的操作，发送指令并使受电设备调整自身的功能。即，
PoE省电策略为受电设备提供了功耗保护机制，防止因受电设备开启过多功能导致功耗超出PoE规范中的功耗限制出现的不稳定。
图5示出根据PoE省电策略管理受电设备功能的实施例的流程图。
如图5所示的实施例，用户通过PoE省电策略配置模块中的交互子模块对受电设备的LCD背光亮度进行修改。
PoE省电策略配置模块将修改后的新亮度数据及原始亮度数据传输至PoE功耗估算模块。
PoE功耗估算模块根据新亮度数据估算新亮度功耗，同时，根据原始亮度数据估算原始亮度功耗。
根据新亮度功耗、原始亮度功耗以及当前的可用功耗，计算新可用功耗，新可用功耗＝当前可用功耗+原始亮度功耗-新亮度功耗。
若新可用功耗大于0，则发送信息至受电设备，设置受电设备的LCD背光到新亮度，并更新受电设备现有的功耗数据。
若新可用功耗小于或等于0，则通过PoE省电策略配置模块中的交互子模块提示用户无法进行LCD背光亮度的修改。
例如，按如图4所示PoE省电策略的交互子模块界面的信息，供电设备可提供的功耗为25.5W，其中，已使用13.00W，可用功耗为12.50W。
假设当前雷电USB、USB3.0和USB2.0均被设置为启用，处于工作状态，其估算的功耗分别为5.60W、4.50W和2.00W。
当前的LCD背光亮度为30％，估算的功耗为0.90W。
计算当前可用功耗，根据当前供电设备的可用功耗以及当前已启用 的功能的功耗，计算当前可用功耗＝12.50W-5.60W-4.50W-2.00W＝0.40W。
若用户试图将LCD背光亮度调整为70％，其估算功耗为3.20W，计算新可用功耗＝0.40W+0.90W-3.20W＝-1.90W<0。
由此可见，新可用功耗小于0，PoE省电策略的交互子模块界面显示“超过PoE功耗限制”的提示信息，用户不能实现将LCD背光亮度调整为70％的目的，可在先禁用部分其他功能后再重新进行调整。
图6示出根据PoE省电策略管理受电设备功能的另一实施例的流程图。
如图6所示的实施例，用户通过PoE省电策略配置模块中的交互子模块对受电设备的蓝牙功能进行启用。
PoE省电策略配置模块发送数据至PoE功耗估算模块，PoE功耗估算模块估算蓝牙功能的功耗。
根据蓝牙功能的功耗和当前的可用功耗，计算新可用功耗，新可用功耗＝当前可用功耗-蓝牙功耗。
若新可用功耗大于0，则发送信息至受电设备，开启受电设备的蓝牙功能，并更新受电设备现有的功耗数据。
若新可用功耗小于或等于0，则通过PoE省电策略配置模块中的交互子模块提示用户无法进行调整或修改。
例如，按如图4所示PoE省电策略的交互子模块界面的信息，供电设备可提供的功耗为25.5W，其中，已使用13.00W，可用功耗为12.50W。
假设当前雷电USB、USB3.0和USB2.0均被设置为启用，处于工作状态，其估算的功耗分别为5.60W、4.50W和2.00W。
当前的LCD背光亮度为30％，估算的功耗为0.90W。
计算当前可用功耗，根据当前供电设备的可用功耗以及当前已启用的功能的功耗，计算当前可用功耗＝12.50W-5.60W-4.50W-2.00W＝0.40W。
若用户试图开启蓝牙功能，其估算功耗为1.00W，计算新可用功耗＝0.40W-1.00W＝-0.60W<0。
由此可见，新可用功耗小于0，PoE省电策略的交互子模块界面显示“超过PoE功耗限制”的提示信息，用户不能实现开启蓝牙功能的目的，可在先禁用部分其他功能后再重新进行开启。
