 背景技术
随着信息技术和网络技术的高速发展以及人们居住理念的变化和提升，家居智能化逐渐成为热门话题，智能家居行业也被誉为是未来的朝阳产业。智能家居系统是指利用综合布线技术、网络通信技术、安全防范技术、自动控制技术、音视频技术将家居生活有关的设施集成，构建高效的住宅设施与家庭日程事务的管理系统，提升家居安全性、便利性、舒适性、艺术性，并实现环保节能的居住环境。而智慧家庭系统中的智能设备（例如，智能电视、智能室内对讲分机装置、智能机器人装置、智能网关、智能路由器）都是通过集成多网络、多传感器技术，承担着为用户提供安全保障、智慧控制、智慧互动、智慧娱乐、环境监测、远程医疗/教育等多项服务，因此智能设备都必须以电能为能源驱动。
目前，智能设备的供电方式有两种：零火线回路供电（又称为无负载回路供电或交流插座取电）；低压直流回路供电。其中，对于低压直流回路供电方式，通常是物业为室内对讲分机预留的直流接口，由于传统对讲分机直流供电功率较小，物业统一供电费用在可承受范围之内，但是，如果物业统一供电的智能设备自带大功率模块时，整个物业社区会产生巨大的公摊费用，这也是业主与物业所不愿见到的情况，所以并不适合大功率的智能设备。对于零火线回路供电方式，在实际应用中发现，市场上智能设备的种类、外观多种多样，各个智能设备的安装位置也不相同。而对于一些家庭住宅，尤其是老旧小区，在特定位置并无为智能设备供电用的交流或直流接口，或者，虽有插座接口，但插座接口的位置（例如国标规定普通电源插座底边距地宜为300mm）并不合适智能设备的安装，这将大大限制智能设备的普及化应用。用户如果要在家中安装所购买的智能设备，又要面临布线问题，影响视觉效果、容易发生不安全事件或增加施工难度。
另外，用户住宅在装修时，开关面板（例如，客厅灯、卧室灯的开关面板）一般都会设置在距地1300mm位置处。该高度虽然正好适合一些智能设备的安装，但是，由于开关布线普遍采用的是单火线回路（与灯具串联的回路），而智能设备需要零、火线回路（即无负载回路）供电才不影响其它回路。如果将智能设备接入负载回路并从负载回路的火线上取电，当负载开通时，虽然可实现智能设备的取电，但是当负载关闭时，必须保证负载回路中有微小的电流来维持智能设备的运行，而这样对于一些对电流敏感的负载，例如小功率LED灯或节能灯，由于关闭灯后负载回路中仍存在小电流，在一些环境下（例如晚上），用户可能会明显感觉到灯会微微发亮或闪烁，因此对用户造成不适的感觉，用户体验较差。

 附图说明
为了更清楚地说明本发明实施例或现有技术中的技术方案，下面将对实施例或现有技术描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本发明的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他的附图。附图中：
图1是本发明智能设备的取电电路实施例一的逻辑结构图；
图2是本发明智能设备的取电电路实施例二的逻辑结构图；
图3是本发明智能设备的取电方法实施例一的流程图；
图4是本发明智能设备实施例一的逻辑结构图。
 本发明的实施方式
图1是本发明智能设备的取电电路实施例一的逻辑结构图，首先说明的是，智能设备例如为安装在家庭、会议室、展厅、宾馆等室内的智能电视、智能室内对讲分机装置、智能机器人装置、智能网关、智能路由器等设备，智能设备包括有处理器、传感模块、音/视频采集模块、通讯模块等多种能耗模块，因此，智能设备的运行需要可靠的供电。
在该实施例中，智能设备的取电电路能从第一负载所在的交流回路的第一火线上取电，第一负载例如为安装在客厅/卧室/餐厅/厨房/卫生间/会议室/展厅/宾馆的灯、风扇等装置。而且，该取电电路与智能设备的处理器相连，能从处理器接收控制信号。该实施例的取电电路包括有：控制单元11、切换开关12、AC/DC单元13、智能开关14、单火线取电单元15、供电单元16、充电单元17、储能单元18。其中，切换开关12的输入端通过第一负载连接第一零线N1，切换开关12的第一输出端连接AC/DC单元13的第一输入端，AC/DC单元13的第二输入端连接第一火线L1，AC/DC单元13的输出端连接供电单元16，且还依次通过充电单元17、储能单元18连接供电单元16。切换开关12的第二输出端通过智能开关14连接单火线取电单元15的第一输入端，单火线取电单元15的第二输入端连接第一火线L1，单火线取电单元15的输出端依次通过充电单元17、储能单元18连接供电单元16。而且，控制单元11用于根据从处理器（未示出）接收的第一控制信号，在确定用户有开启第一负载需求时，控制切换开关12的输入端与其第一输出端连接；在确定用户无开启第一负载需求时，控制切换开关12的输入端与其第二输出端连接；还用于根据从处理器接收的第二控制信号，在确定当前满足第一条件时，控制智能开关14断开；在确定当前满足第二条件时，控制智能开关14接通。其中，所述第一条件为：光照强度低于预设照度值，且用户在特定位置范围内，同时，储能单元的电量不低于预设值；第二条件包括下列中的至少一个：光照强度不低于预设照度值；用户不在特定位置范围内；特定位置范围内的第二负载已开启；储能单元的电量低于预设值。
关于上述实施例，需说明的是，特定位置范围是指第一负载流过弱电流时的影响范围，例如，第一负载为安装在卧室的灯时，当其流过弱电流时，会影响到该卧室内的人，因此，特定位置范围指该卧室的空间范围。而第二负载例如指该卧室内的其它灯。另外，AC/DC单元13在工作时，回路中的电流较大，因此，其不但直接通过供电单元16为智能设备供电，还通过充电单元17为储能单元18充电，且为快充充电方式。单火线取电单元15在工作时，回路中的电流较小，因此，其仅通过充电单元17为储能单元18充电，且为慢充充电方式。当智能开关14关断时，储能单元18才通过供电单元16为智能设备供电。
下面结合图1说明该取电电路的工作过程：
当智能设备的处理器确定用户有开启第一负载需求时，例如，通过传感模块确定用户傍晚下班；通过控制面板的按键或通过通讯模块接收到打开指令，便向切换开关12发送切换指令，使切换开关12的输入端与其第一输出端相连，这样，第一零线N1便经第一负载、AC/DC单元13及第一火线L1形成回路，第一负载及AC/DC单元13均开始工作，AC/DC单元13输出的电能通过供电单元16为智能设备供电，同时，还通过充电单元17为储能单元18充电。
当智能设备的处理器确定用户无开启第一负载需求时，例如，通过传感模块确定用户离家；通过控制面板的按键或通过通讯模块接收到关闭指令，便向切换开关12发送切换指令，使切换开关12的输入端与其第二输出端相连。同时，智能设备的处理器还判断当前满足第一条件或第二条件。当满足第一条件时，即，同时满足以下三个条件：光照强度低于预设照度值，用户在特定位置范围内，储能单元的电量不低于预设值，控制智能开关14断开，此时，第一负载及单火线取电单元15均停止工作。由于切断了第一负载的交流回路，所以第一负载并没有电流流过，也就不会发生微弱电流的影响。当满足第二条件时，即，满足下列任意一个时：光照强度不低于预设照度值；用户不在特定位置范围内；特定位置范围内的第二负载已开启；储能单元的电量低于预设值，控制智能开关14接通，以使第一零线N1经第一负载、单火线取电单元15及第一火线L1形成回路，且通过充电单元17为储能单元18充电。
图2是本发明智能设备的取电电路实施例二的逻辑结构图，该实施例的取电电路相比图1所示的实施例，所不同的仅是，还包括有DC/DC单元19，而且，DC/DC单元19的两输入端分别连接直流接口的两输出端DC+、DC-，DC/DC单元19的输出端连接供电单元16，且还依次通过充电单元17、储能单元18连接供电单元16，该直流接口可输出12-48V的直流电。该直流接口可为物业为室内对讲分机预留的直流接口，还需说明的是，目前室内智能设备中只有室内对讲分机由物业统一供电，其它智能设备需用户配置强电电源供电。而传统对讲分机直流供电功率较小，物业统一供电费用在可承受范围之内，但如果智能设备自带大功率模块时，整个物业社区会产生巨大的公摊费用，这也是物业所不愿见到的情况，因此，如果用户将智能设备安装在预留的室内对讲分机的位置处，可直接从直流接口上取电，但考虑到智能设备的能耗较大，所以可设置仅在特定情况下才从该直流接口取电。在一个具体实施例中，第一条件包括：
光照强度低于预设照度值，且用户在特定位置范围内，同时，储能单元的电量不低于预设值；或者，
当前时间处于预设时段内，且DC/DC单元有电源输入，同时，储能单元的电量低于预设值；
所述第二条件包括：
光照强度不低于预设照度值；或者，
用户不在特定位置范围内；或者，
特定位置范围内的第二负载已开启；或者，
当前时间不处于预设时段内或DC/DC单元无电源输入，而且，储能单元的电量低于预设值。
在该实施例中，即使在储能单元的电量较低时，假如DC/DC单元有电源输入且当前处于预设时段（可设置小区用电的低谷时段，例如，晚22:00至早6:00），此时，智能设备可从直流接口取电，因此可不必接通智能开关14，也就降低了单火线取电单元15的工作频率，从而减少给用户造成不适感觉的几率。
另外，AC/DC单元13的第一输入端还连接第二交流插座接口的第二零线N2，AC/DC单元13的第二输入端还连接第二交流插座接口的第二火线L2。
在该实施例中，智能设备的壳体上开有至少二个取电窗，该取电电路可从第一负载的单火线上取电，也可从无负载的交流插座接口上取电，还可从低压直流接口上取电，取电方式多，可满足无布线地安装在不同的位置需求。
图3是本发明智能设备的取电方法实施例一的流程图，该实施例的取电方法应用于上述实施例的取电电路，且具体包括以下步骤：
步骤S11.判断用户是否有开启第一负载的需求，若是，则执行步骤S12；若否，则执行步骤S13；
步骤S12.控制切换开关的输入端与其第一输出端连接，以使第一零线经第一负载、AC/DC单元及第一火线形成回路，且通过供电单元为智能设备供电，及通过充电单元为储能单元充电；
步骤S13.控制切换开关的输入端与其第二输出端连接，并判断当前满足第一条件或第二条件，若满足第一条件，则执行步骤S14；若满足第二条件，则执行步骤S15；
步骤S14.控制所述智能开关断开，以停止储能单元的充电；
步骤S15.控制所述智能开关接通，以使第一零线经第一负载、单火线取电单元及第一火线形成回路，且通过充电单元为储能单元充电。
在另一个实施例中，本发明的取电方法还进一步地，包括：
AC/DC单元还从第二交流接口取电，并通过供电单元为智能设备供电，且通过充电单元为储能单元充电。
在另一个实施例中，本发明的取电方法还进一步地，包括：
DC/DC单元从直流接口取电，并通过供电单元为智能设备供电，且通过充电单元为储能单元充电，而且，
第一条件包括：
光照强度低于预设照度值，且用户在特定位置范围内，同时，储能单元的电量不低于预设值；或者，
当前时间处于预设时段内，且DC/DC单元有电源输入，同时，储能单元的电量低于预设值；
所述第二条件包括：
光照强度不低于预设照度值；或者，
用户不在特定位置范围内；或者，
特定位置范围内的第二负载已开启；或者，
当前时间不处于预设时段内或DC/DC单元无电源输入，而且，储能单元的电量低于预设值。
图4是本发明智能设备实施例一的逻辑结构图，该实施例的智能设备包括壳体（未示出）、处理器20、取电电路10及能耗模块30，而且，取电电路10通过壳体后侧的取电窗接入第一负载所在的交流回路，其中，第一负载为安装在客厅/卧室/餐厅/厨房/卫生间/会议室/展厅/宾馆的灯、风扇等装置。取电电路10的逻辑结构与工作原理如前述实施例所述，在此不做赘述。
进一步地，能耗模块30例如包括传感模块、音/视频采集模块、通讯模块、其它智能开关等，其中，传感模块可包括有光照传感器、人体传感器、距离传感器。
在一个可选实施例中，处理器20用于根据时间信息和/或光照传感器的检测数据确定当前光照度是否低于预设照度值；用于根据下列的至少一种数据来判断用户是否在特定位置范围内：人体传感器的检测数据、距离传感器的检测数据、音频采集模块的采集数据、视频采集模块的采集数据。
在一个具体实施例中，至少一个单发单收的第一距离传感器，和/或，至少一个多发多收的第二距离传感器，组成上感测模块，以对所形成的上探测空间内的目标物进行距离感测；至少两个单发单收的第一距离传感器，和/或，至少一个多发多收的第二距离传感器，组成下感测模块，以对所形成的下探测空间内的目标物进行距离感测，且下探测空间与上探测空间至少部分交叉。而且，处理器通过实时获取下感测模块的感测数据及上感测模块的感测数据，并根据所获取的感测数据实时确定目标物的三维位置坐标，然后判断目标物是否为特定用户，并判断特定用户的三维位置坐标是否在特定位置处。
在另一个具体实施例中，智能设备的壳体上设置多个人体传感器，以在智能设备的外围形成大于180度的人体感测区域。处理器实时获取各个人体传感器的感测数据，若预设时段内检测到至少两个相邻的人体传感器触发，则对所述至少两个相邻的人体传感器的感测数据进行处理，以获取感测特征信息，所述感测特征信息包括人体传感器的触发时间、触发顺序及感测区域，然后再根据感测特征信息确定用户的当前需求信息，例如，在早上七点至七点半的时段内，先触发第一人体传感器（探测玄关区域），再触发第二人体传感器（探测门口区域），则可确定用户离家上班，进而确定用户有关闭灯（第一负载）的需求；在晚上六点半至七点半的时段内，先触发第二人体传感器，再触发第一人体传感器，则可确定用户下班回家，进而确定用户有开灯（第一负载）的需求。
在再一个具体实施例中，智能设备与用户楼栋单元门口的单元机通讯连接，当楼栋单元机感知到傍晚时间用户开门禁进入楼栋单元门时，可向智能设备发送用户回家的通知，智能设备进而可确定用户有开灯（第一负载）的需求。
进一步地，本发明的智能设备还包括设置在壳体上且与供电单元和控制单元相连的LED灯带。在该实施例中，若第一负载为灯，则可将第一负载拆掉，直接用智能设备上的LED灯带来取代第一负载的功能，这样可彻底消除第一负载在流过弱电流时给用户造成的不适感觉。
进一步地，本发明的智能设备中，控制单元还与用于控制设置在室内的至少一个第三负载的第三智能开关相连，且第三智能开关的控制模块与供电单元的输出端相连。在该实施例中，由于第三智能开关的控制模块直接从智能设备的供电单元取电，相比现有技术中第三智能开关的控制模块从单火线取电的方式，也可消除控制模块所在的取电回路中的第三负载在流过弱电流时给用户造成的不适感觉。
进一步地，本发明的智能设备中，还包括通讯模块，且控制单元还通过通讯模块与用于控制设置在室内的至少一个第四负载的第四智能开关相连。
