目前，随着科技的发展，物联网技术越来越普及。智能开关就是物联网的代表产物。简单的替换目前使用的墙壁开关，特别是标准的墙壁开关，家里老旧的机械开关简单替换成智能开关就赋予了对应的用电设备运算、记忆和联网功能。加上智能设备特别是智能手机的大范围普及，用手机控制家里的用电设备变得轻而易举。而且可以很方便的实现智能控制。比如在看电视时用手机遥控打开房间灯、在公司远程打开家里的电器、为电器设置定时开关功能，安装带语音控制的智能开关实现语音控制。
相关技术的智能开关包括电子开关。请参考图1，图1为相关技术的智能开关的应用示意图。智能开关的第一端连接至墙壁开关底盒的火线，智能开关的第二端连接至墙壁开关底盒的零线，智能开关的第三端通过串联至灯具后连接至零线。
然而，相关技术的智能开关一般带背光，电容式触摸按键，靠近自动亮背光灯，可远程手机操控，带定时控制，场景模式等，需要零线供电，才能提供足够的工作功率。由于平常居民家中的灯具开关为机械开关，一般的机械开关安装的墙壁底盒内部只有1根火线和若干根到电灯的控制线。如果将机械开关替换为智能开关必须要再增加一条零线。但对于绝大部分家庭为美观而埋墙走线的开关来说增加这条零线可以说是困难重重，成本高，需要聘请凿墙、电工、补墙、装修师傅。这条零线的缺失成了智能开关进入千家万户的拦路虎。因此，如何解决无零线插座盒安装需要零线接入的智能开关的供电问题是一个需要解决的技术问题。
因此，实有必要提供一种新的技术方案解决上述问题。

本发明提供了一种供电控制系统100。
同时请参考图2-3所示，图2为本发明供电控制系统100的结构示意图；图3为本发明供电控制系统的应用示意图。
所述供电控制系统100包括具有内部电子开关K1的智能开关1、火线分时导通器2、零线分时发生器5以及负载设备4。

所述供电控制系统100的电路连接关系为：
所述智能开关1的火线端连接至火线，所述智能开关1的火线输出端连接至所述火线分时导通器2的输入端。
所述智能开关1的零线端分别连接至所述火线分时导通器2的输出端、所述零线分时发生器5的输出端，以及所述负载设备4的第一端。
所述零线分时发生器5的输入端分别连接至零线和所述负载设备4的第二端；所述零线分时发生器5与所述负载设备4并联设置。
所述火线分时导通器2还包括温度保护电路(图未示)，所述温度保护电路用于在内部温度超过预设阈值时将所述火线电子开关22关断。所述温度保护电路可防止所述负载设备4过大发热。
本实施例中，所述负载设备4为照明灯。其中，连接线为控制线6，供电控制系统100通过分时导通技术把一线分别作零线和火线两用，控制线6可以在一定周期里导通为火线对负载设备4供电。也可以在一定周期里发生零线对智能开关1供电。
内部电子开关K1断开控制零线分时发生器5直接导通，零线经过零线分时发生器5导通到智能开关的零线端，以实现对智能开关1的零火线供电；内部电子开关K1闭环控制火线分时导通器2导通给负载设备4分时供电，并根据设定在交流电正弦波的过零点一次或者多次截止相应的时间，以使零线分时发生器检测到火线分时导通器2导通时自动截止，以及当零线分时发生器5检测到火线分时导通器2截止时自动导通把零线导通给智能开关1分时 供电，以实现对智能开关1的零火线供电。
所述智能开关1、火线分时导通器2以及零线分时发生器5均为本领域常用的模块或芯片，具体型号和指标选择，根据实际设计需要进行选择，在此，不做详细赘述。
请参考图4所示，图4为本发明火线分时导通器2的模块结构示意图。
所述火线分时导通器2包括火线分时控制产生电路21和火线电子开关22。
所述火线分时控制产生电路21用于产生火线开关控制信号。所述火线开关控制信号为通过交流电正弦波的过零点作为基准进行火线功能的分时控制，以实现对所述负载设备4进行周期性供断电。

所述火线电子开关22的第二端作为所述火线分时导通器2的输出端，且连接至所述火线分时控制产生电路21的第二端。
所述火线分时控制产生电路21的输出端连接至所述火线电子开关22的控制端。
请参考图5所示，图5为本发明火线分时导通器2的一种实施例的电路原理图。本实施例中，本发明火线分时导通器2采用微控器实现。具体的，微控器型号为单片机FT61F020-URT，图5中的R1、R2和单片机U1的3脚(3脚为中断和模拟数字转换管脚)组成过零检测和电压检测电路。图5中的R4、RT1和U1的4脚(4脚为模拟数字转换管脚)组成温度检测和高温保护功能。图5中的单片机U1的6脚控制电子开关通断，如上文所述电子开关是分时导通的。断开时为智能开关和自身供电，导通时为照明灯供电。
当然，不限于此，火线分时导通器2还可以采样分立元器件实现。请参考图6所示，图6为本发明火线分时导通器2的另一种实施例的电路原理图。在另一种实施例中，火线分时导通器2通过可控硅控制电路实现。具体的，图6中的D1、R1、C2调整可控硅BT1导通的电压。断开时为智能开关供电，导通时为灯供电。图6中的K1是温度开关,是过热保护电路。图6中的R4的取值决定过热保护后可控硅的电压输出降低的幅度，不接则直接断开。
请参考图7所示，图7为本发明零线分时发生器的模块结构示意图；
所述零线分时发生器5包括零线分时控制产生电路51、零线电子开关52、快速电流监控电路53以及与逻辑器件54。
所述零线分时控制产生电路51用于产生零线开关控制信号。所述零线开关控制信号为检测所述火线分时导通器2输出端状态产生在截止导通时启动预设第二导通时间的导通状态， 并在所述火线分时导通器2导通时截止的信号。
所述零线分时发生器5的连接关系为：
所述零线电子开关52的第一端作为所述零线分时导通器的输入端，且连接至所述零线分时控制产生电路51的第一端。
所述零线电子开关52的第二端连接至所述快速电流监控电路53的第二端。
所述快速电流监控电路53的第一端作为所述零线分时导通器的输入端，且连接至所述零线分时控制产生电路51的第二端。
所述零线分时控制产生电路51的输出端连接至所述与逻辑器件54的第一端，所述快速电流监控电路53的输出端连接至所述与逻辑器件54的第二端。
所述与逻辑器件54的输出端连接至所述零线电子开关52的控制端。
所述零线分时导通器4还包括过压过流保护电路，所述过压过流保护电路用于在输入过压过流时将所述零线电子开关52关断。
相关技术中的普通的单火线智能开关供电时，总会有电流流过其控制的外部负载。当用电设备功率太小时，其等效内阻太大。无法提供足够的电能给智能开关，致使智能开关无法正常工作。或者智能开关工作了，但即使在开关关闭状态下负载依然在工作(如某些小功率LED等，小电流下就会微亮或者闪亮)！又或者当负载损坏时，智能开关就不能正常工作了，此时智能开关上控制的其他设备也无法工作了。而且这时不好判断是智能开关损坏还是负载损坏。
这时给负载设备4并接零线分时发生器5就能完美解决此问题，即便负载设备4损坏都不会影响智能开关1的正常工作。而且在关闭负载设备4的时候还能把零线直接跳过负载连接到智能开关1。实现彻底关闭负载，不会导致灯负载微亮或者闪亮。
智能开关1的内部电子开关K1断开时，零线分时发生器5的快速电流监控电路53检测断开，就会马上导通零线分时发生器5中的电子开关，把零线直接导通到智能开关1的N(零线输入)上。也就是说，零线分时发生器5就会直接导通，这时候零线就会接通到智能开关1的零线接口，实现对智能开关1的零火供电。此时实现对智能开关1供电，也把负载设备4的供电完全关断，没有任何电流从负载设备4流过，避免造成负载设备4没有完全关闭的微亮或闪烁现象以及能量的损耗，有效降低对负载设备4寿命的影响。
请参考图8所示，图8为本发明零线分时发生器的一种实施例的电路原理图。本实施例中，本发明零线分时发生器5采用微控器实现。具体的，微控器型号为单片机FT61F020-URT，图8中的R1、R2和单片机U1的3脚(中断和模拟数字转换)组成过零检测和电压检测电路。 图8中的单片机U1的6脚控制电子开关通断，所述电子开关是分时导通的。导通时为智能开关提供地线，断开时为灯和自身供电。
当然，不限于此，零线分时发生器5还可以采样分立元器件实现。请参考图9所示，图9为本发明零线分时发生器5的另一种实施例的电路原理图。在另一种实施例中，具体的，图9中的D1/D2/D3/D4组成整流电路，把交流电变成直流电。图8中的R4和Q1组成电子开关。图8中的R3和R2组成电压检测电路，电压在过零点后开始升高，达到设定电压值时，图8中的Q2导通同时令Q1断开实现零线分时发生。而图8中的R5、D5的加入则组成过流限制。图8中的FS1、RV1是电流和电压保护元件。
需要指出的是，本实施例中提到的电路、电容、可控硅、以及芯片均为本领域常用的元器件和芯片，具体型号和指标选择，根据实际设计需要进行选择，在此，不做详细赘述。
绝大部分交流用电设备都是工作在100～240VAC电压，频率50～60Hz的正弦波交流电下。本发明电控制系统100就是基于交流电的电压正负交替变化，实现火线分时导通器2和零线分时发生器5的完美同步工作。为方便说明，下面统一以中国标准的220VAC/50Hz单相交流电进行具体分析说明：
请同时参考图10-11所示，图10为本发明供电控制系统100的信号波形图。图11为本发明供电控制系统100的信号的分时控制波形图。其中，图10中的阴影部分为零线分时发生器5的导通时间tN，是给智能开关1供电的导通时间；空白波形部分为火线分时导通器2导通时间tL，是给所述负载设备4供电的导通时间。
开关K1断开，火线分时导通器2停止工作，零线分时发生器5内部电压检测电路可以快速而准确地检测到这种状态，零线分时发生器5直接把零线导通到智能开关1，实行智能开关1工作在其正常的零火线方式下供电。
开关K1闭合，当火线分时导通器2断开时，零线分时发生器5自动导通，导通时间tN；当火线分时导通器2导通时，导通时间tL，零线分时发生器5自动断开。零线分时发生器5和火线分时导通器2以交流电正弦波的过零点为参考实现分时控制。
对于灯有特殊要求时，甚至可以动态分配零火分时的导通时间比例和周期。具体的，所述第一导通时间与所述第二导通时间的比例为1:10或者0.5:10。所述第一导通时间与所述第二导通时间共同形成导通周期，所述导通周期为可调参数。在不影响灯负责的前提下零线分时发生器和火线分时导通器的工作方式灵活多样。比如可以每10个周期分配1个周期或半个周期控制线导通零线给智能开关1供电，其他时间控制线导通火线给灯供电。而针对诸如电机类的感性负载，需要过零点的调光、调压设备等，我们可以通过调整火线导通时间tL和零 线导通时间tN分时比例及切入点等方式满足特殊负载的要求。还有基于微控器的高级版本，通过其自身软件调整控制，从频率，占空比，间隙都可以灵活地动态设定零火线分时导通的周期。
火线分时导通器2和零线分时发生器5的灵活组合，使得支持的智能开关1类的产品功率可以从微瓦级别的超低功耗的产品到数十瓦功耗的产品均实现单火线功能,而且保证了极高的效率，绿色环保。同时为本发明供电控制系统100的普及和推广铺平道路。灵活的电源电压适应能力。以交流电正弦波的过零点作为同步控制的基础，可以根据当前电源电压高低，灵活分配零火分时比例。使得本发明供电控制系统100在绝大部分工作条件下均能稳定的输送功率，使智能开关保持长期稳定工作。
本发明供电控制系统100的分时控制在零线分时发生器5和火线分时导通器2分时导通，不会同时导通分时。
火线分时导通器2关断时，零线分时发生器5导通直接给智能开关1供电，导通阻抗非常小而且稳定，比通过不确定阻抗的负载设备4导通过来的零线更高效和稳定(如果串联灯泡功率过小，可能就会出现智能开关不能正常工作)。另外，火线分时导通器2导通时给负载设备4供电，同时零线分时发生器5断开。即便是负载设备4损坏，零线分时发生器5仍然正常工作，也不会影响到智能开关1的供电。
为了更好的电控制系统100应用，零线分时发生器5和火线分时导通器2可同时为安装在同一位置的多个零火线智能开关供电。请参考图12所示，图12为本发明供电控制系统100的其他一种应用示意图。所述内部电子开关K1包括多个，其中一个所述内部电子开关K1的输出端连接至所述火线分时导通器2的输入端，另外的所述内部电子开关K1连接相对应的一个所述负载设备4。该应用可以使得本发明供电控制系统100应用更为广泛。
请参考图13所示，图13为本发明供电控制方法的流程框图。所述供电控制方法应用于所述供电控制系统100。
所述供电控制方法包括如下步骤：
步骤S1、所述零线分时发生器5通过检测所述火线分时导通器2输出端状态，判断所述内部电子开关K1是否闭合：若否，所述零线分时发生器5导通，所述智能开关1的零线端通过所述零线分时发生器5与零线连接。若是，则进入步骤S2。
步骤S2、所述火线分时导通器2在所述第一导通时间内导通，所述零线分时发生器5断开。
步骤S3、所述火线分时导通器2断开，所述零线分时发生器5在所述第二导通时间内导 通后进入所述步骤S1。
与相关技术相比，本发明实施例提供了供电控制系统和供电控制方法，供电控制系统设置了负载设备、智能开关、火线分时导通器以及零线分时发生器；将零线分时发生器与负载设备并联，供电控制系统在智能开关控制下进入两种工作状态，一种工作状态是：在智能开关的内部电子开关断开时，所述火线分时导通器的输入端截止输出，所述零线分时发生器检测所述火线分时导通器的导通状态，在所述火线分时导通器截止导通，从而使得零线直接跳过负载设备连接到智能开关，实现彻底关闭负载设备；另一种工作状态是：在智能开关的内部电子开关闭合时，所述零线分时发生器检测所述火线分时导通器的导通状态，所述零线分时发生器和所述火线分时导通器分时导通，从而使得本发明供电控制系统对零线火线功能切换按周期分配各自导通时间来满足智能开关供电，同时不影响负载设备的正常工作。因此，本发明实施例提供的供电控制系统和供电控制方法在开关底盒没有零线的情况下解决智能开关的零火线供电，易于安装且应用范围广。
