具体实施方式
为使本发明的目的、技术方案和优点更加清楚，以下将参照本发明实施例的 附图，通过实施方式清楚、完整地描述本发明的技术方案，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
参考图1所示，为本发明第一实施例提供的安全智能插座的部分结构示意图。在图1中，壳体左侧是壳体1内的结构，壳体右侧为表面形貌。安全智能插座包括壳体1，在壳体1的插接面设有两组插孔组13，每组插孔组13包括三个插孔13a、13b、13c。在壳体1内设有三组卡片组(图中未示出)，每组卡片组包括三个卡片，三个卡片分别与火线、零线、地线电连接，即每个卡片通过一根导线与电源的火线、零线、地线电连接。卡片用于卡接插头的插片，卡片的位置与插孔的位置相对，使用时，每组插孔组13对应插接一个插头，插头的插片穿过插孔进入壳体1内并与卡片卡接。
不难理解，当使用两相插头时，每组插孔组13包括两个插孔，与该插孔组13对应的卡片组包括两个卡片，一个卡片与火线电连接，另一卡片与零线电连接。换言之，每组插孔组中插孔的数量是与插头的结构相关，当使用两相插头时，每组插孔组设置两个插孔。当使用三相插头时，每组插孔组设置三个插孔。另外，每个安全智能插座可以设置一个插孔组，也可以设置两个或更多个插孔组。而且，当安全智能插座设置多组插孔组时，每组插孔组设置的插孔的数量可以相同，也可不同。
结合参考图1和图2所示，安全智能插座包括还包括检测单元2、智能单元3和执行单元4，其中，检测单元2设于壳体1内，用于获得检测信号。智能单元3可以设置在壳体1内，也可以设置在壳体1外的其它位置，用于分析检测单元2获得的检测信号以及发出命令(接通命令或断开命令)。执行单元4可以设置在壳体1内，也可以设置在壳体1外的其它位置，用于执行智能单元3发出的命令。
检测单元2包括电流检测模块21和光检测模块22。电流检测模块21包括第一电流检测子模块211、第二电流检测子模块212、第一信号处理子模块213和第二信号处理子模块214，其中，第一电流检测子模块211设于火线的外围，用于感应流经火线的电流所产生的磁场并获得相应的火线磁信号。第一电流检测子模块211的输出端电连接第一信号处理子模块213的输入端，第一信号处理子模块213的输出端电连接智能单元3，第一信号处理子模块213用于处理火线磁信 号，并将处理后的火线磁信号传输至智能单元3。第二电流检测子模块212设于零线的外围，用于感应流经零线的电流所产生的磁场并获得相应的零线磁信号。第二电流检测子模块212的输出端与第二信号处理子模块214的输入端电连接，第二信号处理子模块214的输出端电连接智能单元3，第二信号处理子模块214用于处理零线磁信号，并将处理后的零线磁信号传输至智能单元3。
第一信号处理子模块213和第二信号处理子模块214均包括放大电路和过滤电路。第一信号处理子模块213的放大电路与第一电流检测子模块211的输出端电连接，第一信号处理子模块213的放大电路用于放大火线磁信号。第一信号处理子模块213的过滤电路的输入端与第一信号处理子模块213的放大电路的输出端电连接，第一信号处理子模块213的过滤电路用于过滤放大后的火线磁信号。
第二信号处理子模块214的放大电路与第二电流检测子模块212的输出端电连接，第二信号处理子模块214的放大电路用于放大零线磁信号。第二信号处理子模块214的过滤电路的输入端与第二信号处理子模块214的放大电路的输出端电连接，第二信号处理子模块214的过滤电路用于过滤放大后的零线磁信号。
智能单元3接收第一信号处理子模块213处理后的火线磁信号，以及第二信号处理子模块214处理后的零线磁信号，依据处理后的火线磁信号和零线磁信号得出火线和零线的电流差值，并将该电流差值和预设电流差阈值进行比较。
另外，智能单元3收到电流检测模块21获得的并经处理的火线磁信号和零线磁信号后，分析火线磁信号和零线磁信号得出火线和零线的电流值，以及得出使用该插座的用电电器的漏电流。当漏电流超过预设漏电流阈值时，智能单元3发出断开命令。
光检测模块22采用光敏电阻、光敏二极管、光敏三极管或光敏集成器件。光检测模块22可以设置于壳体1内，用于检测壳体1内的光强度，光检测模块22的输出端电连接智能单元3。当插头未插入插座，外界光线从插孔进入壳体1内，此时壳体1内的光线较强，光检测模块22检测到的光强度较大。当插头插入插座时，外界光线无法进入壳体1内，此时壳体1内的光线很弱，光检测模块22检测到的光强度很小。
此外，光检测模块22还可设于壳体1的接触面，即设于插座与插头的接触面，优选设于三个插孔的中间区域，用于检测插座和插头接触面位置处的光强度。当插头插入插座时，插头将光检测模块22的感光面被遮挡，光检测模块22检测到的光强度很小。当插头未插入插座时。光检测模块22的感光面能够感应外界 的光线，光检测模块22检测到的光强度较大。在图1所示的安全智能插座中，光检测模块22设置在三个插孔13a、13b、13c的中间区域，光检测模块22的感光面与壳体1的接触面平齐或略低于壳体1的接触面，主要目的是避免光检测模块22影响插头与插座的插接。
智能单元3接收来自光检测模块22的光强度信号，比较光强度预设光强度阈值。当电流差值低于预设电流差阈值以及光强度低于预设光强度阈值时，智能单元3发出接通命令；当电流差值超过预设电流差阈值，或者光强度超过预设光强度阈值时，智能单元3发出断开命令。
执行单元4用于执行智能单元3发出的命令，执行单元4为电磁继电器或固态继电器或晶闸管。优选地，在火线和零线上分别设置一执行单元4，当执行单元4收到智能单元3发出的断开命令时，插座的火线和零线同时切断与电源的电连接，从而提高插座的安全性。但在实际应用中，安全智能插座也可以仅在火线上设置一执行单元4，当执行单元4收到智能单元3发出的断开命令时，执行单元4仅切断火线与电源的电连接。或者，安全智能插座在火线、零线、地线上分别设置一执行单元4，当执行单元4收到智能单元3发出的断开命令时，执行单元4将火线、零线、地线与电源电连接全部切断。
在本实施例中，第一电流检测子模块和第二电流检测子模块采用相同结构的电流检测子模块。参考图3所示，电流检测子模块分别包括传感器31、线圈32和环状的铁芯33，线圈32缠绕在铁芯33的外侧，在铁芯33上设有缺口34，传感器31设于铁芯33的缺口位置，火线和零线分别穿过对应的线圈32。传感器31为巨磁阻(Giant Magneto Resistance，简称GMR)传感器、隧道磁电阻(Tunnel Magneto Resistance，简称TMR)传感器或霍尔传感器等芯片传感器。安全智能插座采用芯片传感器，具有以下优点：其一，测量精度高，计量范围宽，可以精确测量电器的用电量；二，响应速度快，可靠性高，能够准确、快速地获得流入电器的电流；其三，自身功耗低，使用费用低；其四，集成度高，体积小，安全智能插座的外形尺寸与普通插座的外形尺寸相当；其五，以非接触式测量火线和零线的电流，电流任何幅度的波动都不会损坏智能单元，从而提高智能单元的可靠性，进而提高安全智能插座的可靠性及使用寿命。这种安全智能插座适用于不同类型、不同品牌的家用电器，使用时，只需将电器的插头插入智能插座的插孔内即可，这可以减少家用电器的能耗，还可以降低改造家用电器的难度和时间。
本发明第一实施例提供的安全智能插座利用电流检测模块和智能单元获得 火线和零线的电流差值，利用光检测模块获得壳体内的光强度，当电流差值低于预设电流差阈值以及光强度低于预设光强度阈值时插座与电源电连接，即当电流差值和光强度同时满足预设条件时插座正常工作，当电流差值超过预设电流差阈值或者光强度超过预设光强度阈值时插座停止工作，即当电流差值和光强度二者之一不满足预设条件则断开插座与电源的电连接，这样既能防止电器的漏电，又能避免误操作导致的触电，如小孩将手指或其它导体插入插孔，两种措施综合利用、相互补充，从而有效地提高插座的安全性和可靠性。
第一实施例提供的安全智能插座采用光检测模块22来判断插头和插座是否插接，外界光线对插座的准确性有较大影响。例如当需要断开插座和电源的电连接时，需要避免外界的光线对光检测模块22的灵敏度的影响。为了提高安全智能插座的准确性，壳体1采用遮光材料制作。为了进一步提高安全智能插座的准确性，还需对壳体1的结构进行改进。
参阅图4所示，为本发明第二实施例提供的安全智能插座的结构示意图，该图是将壳体1的接触面去掉，示出了壳体1内部的结构。第二实施例是第一实施例的变型实施例，在壳体1内设有分离部15，分离部15将壳体1的内部分离成第一腔室1A和第二腔室1B，与零线和火线电连接的卡片14b、14c以及光检测模块22设于第一腔室1A，与地线电连接的卡片14a设于第二腔室1B。当光检测模块22设于壳体1内时，光检测模块22主要受插孔透入壳体1内的光的影响，减少插孔可以减少外界光对光检测模块22的影响。将与地线相对应的插孔分离，可以减少外界光对光检测模块22的影响，从而提高安全智能插座的可靠性和准确性。
本发明的第二实施例提供的安全智能插座由于从插孔内投入的光线会影响光检测模块的精度，因此将壳体内分为两个腔室，并将与零线和火线电连接的卡片以及所述光检测模块设于所述第一腔室，与地线电连接的卡片设于第二腔室，将与地线电连接的卡片设置于其它腔室，与地线电连接的卡片所对应的插孔不会影响第一腔室的光强度，从而提高安全智能插座的安全性。
需要说明的是，为了便于描述，以下一些实施例中不再提及壳体1，但这并不表示以下各实施例提供的安全智能插座不包含壳体1。另外，由于执行单元4只是用于执行智能单元3的接通命令和断开命令，在以下实施例中不再详细介绍。
参阅图5所示，为本发明第三实施例提供的安全智能插座的原理图。该安全智能插座包括检测单元2、智能单元3和执行单元4。智能单元3是根据检测单元2的变化作相应的改动。具体地，检测单元2包括电流检测模块21、光检测模块22和幼儿特征采集模块23，其中，电流检测模块21和光检测模块22的结构、功能、设置方式与第一实施例相同，在此不再赘述。幼儿特征采集模块23用于采集站在插座前的人的特征信息。智能单元3根据幼儿特征采集模块23采集的特征信息判断站在插座前的人是否为幼儿，并依据此判断发出相应的接通或断开命令。不难理解，在第二实施例中，智能单元3既要判断电流检测模块21和光检测模块22采集到的信息，又要判断幼儿特征采集模块23采集到的信息。
幼儿特征采集模块23可以采集人体的多种特征来判断站在插座前的人是否为幼儿或未成年人，例如可以通过人脸特征和/或身高特征来判断是否为未成年人。对应地，幼儿特征采集模块23包括人脸识别子模块和/或身高识别子模块，其中，人脸识别子模块用于采集站在插座前的人的脸部特征，智能单元3依据人脸识别模块获得的脸部特征判断站在插座前的人是否为幼儿或未成年人。身高识别子模块用于采集站在插座前的人的身高特征，智能单元3依据身高识别模块获得的身高特征判断站在插座前的人是否为幼儿或未成年人。当智能单元3判断站在插座前的人为幼儿，可以选择性地发出断开命令。
需要说明的是，在第二实施例中，幼儿特征采集模块23可以设置在壳体1内，也可设置在壳体1外。当幼儿特征采集模块23设置于壳体1内时，幼儿特征采集模块23可通过插孔采集站在插座前的人的特征信息。
实际上，在某些特殊的应用场合，安全智能插座的检测单元2可以不设置电流检测模块21和光检测模块22，即仅设置幼儿特征采集模块23，当智能单元3判断站在插座前的人为幼儿或未成年人时发出断开命令。虽然这种方式可能会发生不必要的断电，但可有效地防止幼儿和未成年人触电。也就是说，幼儿特征采集模块23并不必须与电流检测模块21和光检测模块22配合使用。当检测单元2设置电流检测模块21、光检测模块22和幼儿特征采集模块23，可以使安全智能插座获得更全面的保护，提高安全性。
本发明第三实施例提供的安全智能插座通过幼儿特征采集模块采集站在插座前的人的特征信息，由智能单元判断站在插座前的人的年龄，当判断为幼儿和未成年人时，发出断开命令，从而有效地避免了小孩触电情况的发生，提高插座的安全性。
参阅图6所示，为本发明第四实施例安全智能插座的原理图。第四实施例是第三实施例的变型，其安全性和稳定性更高。该安全智能插座包括检测单元2、智能单元3和执行单元4。智能单元3根据检测单元2的变化作相应的改动。具体地，检测单元2包括电流检测模块21、光检测模块22、幼儿特征采集模块23和测距模块24，其中，电流检测模块21和光检测模块22的结构、功能、设置方式与第一实施例相同；幼儿特征采集模块23的结构、功能、设置方式与第二实施例相同，因此，在此不再赘述。
测距模块24用于测量站在插座前的人与插座之间的距离。智能单元3依据测距模块获得的距离判断是否为安全距离，若否，则选择性的发出断开命令。为了避免不必要的断开，影响用电电器的正常运行。优选地，测距模块24和幼儿特征采集模块23配合使用。即，当智能单元3依据幼儿特征采集模块23采集的站在插座前的人的特征信息判断为幼儿和未成年人，以及智能单元3依据测距模块24判断站在插座前的人与插座之间的距离为非安全距离，则发出断开命令。
在第四实施例中，测距模块24可以设置在壳体1内，也可设置在壳体1外。测距模块24可以采用红外测距或雷达测距。当测距模块24为红外测距且设置于壳体1内时，测距模块24可通过设置在壳体1上的插孔去测距。
本发明的第四实施例提供的安全智能插座通过测距模块测量站在插座前的人与插座之间的距离，由智能单元判断该距离是否为安全距离，若否，并且，智能单元判断站在插座前的人为幼儿，则发出断开命令，通过距离和幼儿特征双重判断进一步提高了安全智能插座的安全性。
参考图7所示，为本发明第五实施例安全智能插座的原理图。该安全智能插座包括检测单元2、智能单元3和执行单元4。检测单元2包括电流检测模块21、光检测模块22，电流检测模块21和光检测模块22的结构、功能、设置方式与第一实施例相同，在此不再赘述。检测单元2还包括烟雾探测模块25和/或温湿度探测模块26，其中，烟雾探测模块25用于探测环境中的烟雾浓度，智能单元3判断烟雾浓度是否超过预设烟雾浓度范围，若是，则发出断开命令。温湿度探测模块26用于探测环境中的温湿度，智能单元3判断温湿度是否超过预设温湿度范围，若是，则发出断开命令。
第五实施例提供的安全智能插座是将烟雾探测模块25和温湿度探测模块26 配合电流检测模块21、光检测模块22使用。实际上，安全智能插座也可根据使用场合仅设置烟雾探测模块25或温湿度探测模块26，或者仅设置烟雾探测模块25和温湿度探测模块26，当在烟雾浓度超标或温湿度超标时，智能单元3发出断开命令，以切断电源与用电电器的电连接，从而提高用电电器的安全性。
优选地，安全智能插座还可将电流检测模块21、光检测模块22、幼儿特征采集模块23、测距模块24、烟雾探测模块25和温湿度探测模块26集成在一起，从而既提高安全智能插座的安全性，又提高用电电器的安全性。
本发明的第五实施例提供的安全智能插座通过烟雾探测模块25和温湿度探测模块26分别判断插座使用环境的烟雾浓度和温湿度，当烟雾浓度超过预设烟雾浓度范围或者温湿度超过预设温湿度范围时，断开电源与用电电器的电连接，避免火灾或水灾等情况引起漏电，从而提高安全智能插座以及用电电器的安全性。
参阅图8a所示，为本发明优选实施例提供的安全智能插座的原理图。该安全智能插座包括检测单元2、智能单元3和执行单元4。检测单元2包括电流检测模块21、光检测模块22和位置传感器27，电流检测模块21和光检测模块22的结构、功能、设置方式与第一实施例相同，在此不再赘述。位置传感器27用于检测插头的插片与卡片的相对位置并获得位置信号，并将位置信号传输至智能单元3。智能单元3根据位置信号判断插头的插片与卡片是否插接，若是，则发出接通命令，若否，则发出断开命令。位置传感器27可以是压敏传感器或光敏传感器或测距传感器。位置传感器27可设置于卡片14的底部，如图8b所示，也可设置于卡片14的侧壁，如图8c所示。当将插头插入插座时，通过测距传感器测量插头的插片81与卡片14底部的距离来判断插头与插座是否插接好；或者，通过压敏传感器来感应插头的插片81是否与卡片14插接好；或者，通过光敏传感器来感应插片81是否与卡片14插接好。
本实施例提供的位置传感器27可以配合前文所述第一实施例至第五实施例以及下文各实施例中提及的各部件使用，利用位置传感器获得插片和卡片的相对位置，由智能单元判断插片和卡片是否插接到位，当判断插片和卡片插接时发出接通命令，当判断插片和卡片未插接时发出断开命令，可避免插接不牢固引起火灾等安全隐患，从而提高插座的安全性。
参阅图9所示，为本发明第六实施例提供的安全智能插座的原理图。安全智能插座包括检测单元2、智能单元3、执行单元4、第一通讯模块51和云终端服务器6。
其中，第一通讯模块51与智能单元3连接，用于插座与云终端服务器之间的通讯。如将智能单元3获得的电流值等信息发送至云终端服务器6，以及将来自云终端服务器6命令或信息传送至智能单元3。云终端服务器6根据所述电流值计量用电量，同时进行统计分析得出连接在该安全智能插座上电器的能耗和/或个人使用习惯，并据此得出用电电器的合理使用方式。智能单元3还可进行自我学习，以优化对用电电器的控制。
另外，第一通讯模块51可以采用Wifi模块或Zigbee模块或红外通信模块等无线模块，也可采用有线模块。
本发明第六优选实施例提供的安全智能插座利用第一通讯模块51与云终端服务器6进行通讯，即云终端服务器借助第一通讯模块接收智能单元发来的电流值，然后进行统计与分析，得出电器的用电能耗，个人使用习惯(电器在不同时间的能耗，也称能耗随时间的变化状况)，并根据用电能耗和个人使用习惯提出合理的电器使用方式(建议)。由于云终端服务器具有大数据分析能力，计算能力更强，得出的能耗状况更准确，而且可以根据个人使用习惯以及电器的能耗状况提出合理有效的使用建议。另外，云终端服务器可以通过第一通讯模块将电器的合理使用建议随时发送至智能单元，智能单元通过该使用建议进行自我学习后，可优化对电器的控制，从而降低电器的能耗。此外，云终端服务器也可以通过第一通讯模块对电器进行控制，即云终端服务器通过第一通讯模块将命令发送至智能单元，智能单元再将命令转发执行单元去执行。
参阅图10所示，为发明第七实施例提供的安全智能插座的原理图。安全智能插座包括检测单元2、智能单元3、执行单元4、第一通讯模块51、第二通讯模块52、云终端服务器6和APP手持终端7。
其中，检测单元2、智能单元3和执行单元4与前面六个实施例相同，在此不再赘述。第二通讯模块52与APP手持终端7连接，第一通讯模块51、第二通讯模块52采用相同的协议，APP手持终端7通过第二通讯模块52与云终端服务器6和智能单元3进行通讯，用户通过APP手持终端7可以随时掌握用电电器的用电量、远程控制用电电器以及接收云终端服务器6根据用电电器的能耗和/或 个人使用习惯提出的有关用电量的生活小常识。
在第七实施例中，第一通讯模块51和第二通讯模块52可以采用Wifi模块或Zigbee模块或红外通信模块等无线模块，也可采用有线模块。
本发明第七实施例提供的安全智能插座，APP手持终端和云终端服务器之间通过第二通讯模块实现相互通讯，即APP手持终端可以通过第二通讯模块获得云终端服务器发出的信息，如电器的能耗及电器的合理使用建议等。APP手持终端与智能单元之间通过第二通讯模块进行通讯，即APP手持终端通过第三通讯模块可以获得智能单元发出的信息，如电器的实施能耗状况，也可以向智能单元发命令，即通过APP手持终端可以对电器进行实时控制。
第六实施例和第七实施例提供的安全智能插座能够监控用电电器的能耗并记录分析用电状况，使插座更加智能。借助该安全智能插座可以实现对用电电器的升级改造，相比直接升级改造用电电器而言，实施容易，费用少。
