具体实施方式
以下结合附图和具体实施例对本发明作详细描述。注意，以下结合附图和具体实施例描述的诸方面仅是示例性的，而不应被理解为对本发明的保护范围进行任何限制。
如图1～图3所示，本发明实施例提供了一种智能光伏并网箱303(AC Box)，连接于光伏系统的逆变器302和户用电表箱304之间。该智能光伏并网箱303包括智能电表5、物联网控制器1(IOT)和开关电路，智能电表5采集户用电表箱304的用电数据，智能电表5还与逆变器302信号连接以采集逆变器302的发电数据，智能电表5与物联网控制器1信号连接。逆变器302与物联网控制器1连接，物联网控制器1与云端服务器305信号连接，从而物联网控制器1或云端服务器305能够对所采集到的数据进行分析处理，以控制逆变器302的发电输出。开关电路连接于逆变器302、户用电表箱304、智能电表5和物联网控制器1之间，包括空气开关8和空气开关9以实现并、离网和控制功能。
其中，智能电表5采集户用电表箱的用电数据有两种方式，一种为随AC Box提供电流互感器10，电流互感器10安装于户用电表箱304内，电流互感器10与智能电表5连接。另一种方式为户用电表箱304内原本设置有双向电能表11，物联网控制器1直接连接双向电能表11并采集户用电表箱304内的双向电能表11的数据。
由于智能光伏并网箱303通常装设在地下室或车库，缺乏4G信号/移动网络信号/Wifi信号，故而在可能的实施例中，本并网箱还包括电力线通讯调制解调器7(俗称电力猫)，物联网控制器1借助电力线通讯调制解调器7连接到用户的路由器，路由器再通过互联网与云端服务器305进行数据传输。电力线通讯调制解调器7上设置有单相插座6。通过设置电力猫，在保证了信号传输质量的同时，也节省了网络布线的材料与人工成本。根据电力猫种类的不同，既可以直接采用具有无线通讯功能的电力猫，也可以在本并网箱内设置电力子猫，在路由器出设置电力母猫。
为了实现物联网控制器1与交换机2的连接，在可能的实施例中，该并网箱303还包括交换机2，物联网控制器1借助交换机2与电力线通讯调制解调器7连接。此外，还设置有第一开关电源3和第二开关电源4，以为交换机2、物联网控制器1等提供电力。第一开关电源3和第二开关电源4可以单独设置，也可以合并为一个部件。
逆变器302与智能电表5通过串口通讯(通过RS485接口)、有线网络(通过Ethernet网口)或无线网络(Wifi)连接。在本实施例中，逆变器302通过RS485串口与智能电表5连接。
优选地，本智能并网箱的所有通讯线和网线均采用插拔式接头，以便于现场施工，防止现场接错线。
进一步地，为了方便后续增加设备，在交换机2上留设有备用网络接口，在物联网控制器1上留设有备用通讯接口。
容易理解地，本发明实施例还提供了一种智能光伏并网系统，如图3所示，包括光伏组件301、逆变器302、户用电表箱304、云端服务器305、用户终端306和如上述任一实施例的智能光伏并网箱303，光伏组件301连接逆变器302，逆变器302借助智能光伏并网箱303与户用电表箱304连接，智能光伏并网箱303与云端服务器305信号连接，用户终端306与云端服务器305信号连接。
用户终端306可以为手机、平板电脑、可穿戴设备、车载设备、增强现实(augmentedreality，AR)/虚拟现实(virtual reality，VR)设备、笔记本电脑、超级移动个人计算机(ultra-mobile personal computer，UMPC)、上网本、个人数字助理(personal digitalassistant，PDA)等电子设备。以手机为例，用户可在手机上安装应用程序，以查看用电发电情况。
本系统中的电路连接关系如图4所示，逆变器402通过L1、L2、L3、N开和PE线连接户用电表箱404，智能光伏并网箱303连接于这二者之间。开关电路包括第一空气开关401和第二空气开关407，第一空气开关401连接于逆变器402和户用电表箱404之间，第二空气开关407连接于逆变器402、户用电表箱404、交换机405和物联网控制器406之间。在户用电表箱404上还设置有空气开关QF3，以实现对户用电表箱404的单独控制。
本说明书中各个实施例采用递进的方式描述，每个实施例重点说明的都是与其他实施例的不同之处，各个实施例之间相同相似部分互相参见即可。
提供对本公开的先前描述是为使得本领域任何技术人员皆能够制作或使用本公开。对本公开的各种修改对本领域技术人员来说都将是显而易见的，且本文中所定义的普适原理可被应用到其他变体而不会脱离本公开的精神或范围。由此，本公开并非旨在被限定于本文中所描述的示例和设计，而是应被授予与本文中所公开的原理和新颖性特征相一致的最广范围。
