在一示例性实施例中，状态检测模块2检测太阳能组件5的状态，太阳能组件5的状态包括温度、电流和/或电压等。太阳能组件接线盒可安装在太阳能组件5的背面。
在一示例性实施例中，控制器3获取状态检测数据后，判断状态检测数据是否异常，判断方式例如比较状态检测数据与预设状态 阈值之间的大小，如果状态检测数据大于预设状态阈值，则判定状态检测数据异常。比较功能可通过比较电路实现。
在一示例性实施例中，预设状态阈值为太阳能组件5正常工作时所对应的临界值，状态检测数据超出临界值则表示状态检测数据异常。控制器3获取状态检测数据后，可通过比对预设状态阈值，确定状态检测数据是否异常，比对功能的实现可采用比较电路来实现，也即控制器3中设置有比较电路，比较电路属于成熟技术，本实施例不再赘述。
在一示例性实施例中，控制器3获取状态检测数据后，若确定状态检测数据异常，说明太阳能组件5处于异常环境，异常环境例如火灾、自然灾害或其他有损太阳能组件5的环境，则控制器3生成关断控制信号，用以关断太阳能组件5。
在一示例性实施例中，控制器3生成关断控制信号，关断控制信号可控制电源模块4调整自身的输出电压处于预设的低电压范围，也即电源模块4接收到关断控制信号后，调整自身的输出电压处于预设的低电压范围。

在一示例性实施例中中，不同的有线方式对应的预设个数不同，不同的无线方式对应的预设个数不同。
在一示例性实施例中，若有线方式为RS485方式，则RS485方式对应的预设个数例如为60个至80个范围内的任一个数，RS485方式对应的预设个数的具体取值受限于采用RS485方式进行通信的通信能力，RS485方式对应的预设个数可根据实际情况确定。

在一示例性实施例中，若有线方式为电力载波方式，则连接同一逆变器6的所有太阳能组件接线盒通过电力载波方式(例如电力线)连接同一网关。
下面结合图5至图7，对太阳能系统进行具体说明。太阳能系统根据太阳能组件接线盒的个数可以分为两层结构和三层结构。
如果太阳能组件接线盒的个数未超过有线方式对应的预设个数，则采用如第二示例性实施例所述的两层有线结构，例如太阳能组件接线盒通过RS485或电力载波等有线方式与太阳能控制器通讯。
如果太阳能组件接线盒的个数未超过无线方式对应的预设个数， 则采用如第二示例性实施例所述的两层无线结构，例如太阳能组件接线盒通过ZigBee或蓝牙等无线方式与太阳能控制器通讯。
如果太阳能组件接线盒的个数超过有线方式对应的预设个数且超过无线方式对应的预设个数，则采用如第三示例性实施例所述的三层结构，三层结构的太阳能系统包括三种典型的通讯架构方案：有线方案、无线方案及有线与无线混合方案。
有线方案：采用RS485或电力载波方式，具体地，如图5所示，每一百个左右太阳能组件接线盒通过RS485连接一个网关，也可根据实际现场环境调整一个网关连接的太阳能组件接线盒的数量。当采用电力载波方式通讯时，网关的数量可根据逆变器的数量来配置，一个逆变器连接的所有太阳能组件接线盒可使用一个网关，网关再通过RS485等有线方式与太阳能控制器连接，实现整个太阳能系统的通讯连接。
无线方案：采用ZigBee加LoRa或NB-IoT的方式，具体地，如图6所示，太阳能组件接线盒以几十到一百个左右为单位，组成一个ZigBee网络，每一个ZigBee网络设置一个网关，网关由LoRa模块与ZigBee通信模块构成，LoRa模块与ZigBee通信模块之间通过串口连接，其中ZigBee通信模块可以为cc2530芯片或cc2538芯片。网关负责与各个太阳能组件接线盒的无线通讯。LoRa模块通讯有两种方式：第一种采用LoRaWAN，针对于远距离通信网络设计的一套通讯协议和系统架构，具有体积小、功耗低、传输距离远、抗干扰能力强等特点，可根据实际应用情况对天线增益进行调节。LoRaWAN是一个典型的星形拓扑结构，在这个网络架构中，太阳能控制器是一个透明的中继，连接LoRa模块和太阳能服务器(图中未示出太阳能服务器，太阳能服务器也即图1中服务器层所包括的太阳能服务器)，太阳能控制器与太阳能服务器通过标准IP(互联网协议)连接，太阳能控制器和LoRa模块间以星形网方式组网，太阳能 控制器可以实现多通道并行接收，同时处理多路信号，所有的LoRa模块与太阳能控制器之间均是双向通信，增加了网络容量。第二种采用点对点轮询的方式组网，但是点对点轮询效率要远低于星形网，点对点轮询的方式组网的好处是在通讯协议和系统方面便于实现，研发和工程成本相对较低，比较适用于太阳能组件接线盒数量较少的项目当中，一般在少于500个接线盒的项目中均可以采用太阳能控制器与网关点对点轮询的方式组网。
另外，NB-IoT是物联网领域一个新兴的技术，支持低功耗设备在广域网的蜂窝数据连接，也即低功耗广域网(LPWAN)。NB-IoT构建于蜂窝网络，可直接部署于GSM网络、UMTS网络或LTE网络。NB-IoT模块在无线方案中可以直接替代LoRa模块和太阳能控制器的功能，因此通过两层无线网络即可实现太阳能组件接线盒与服务器之间的数据通讯。
有线与无线混合方案，即RS485与ZigBee相结合的方式，或电力载波与LoRa相结合的方式，具体地，如图7所示，采用RS485加ZigBee通信模块的通讯架构，其中ZigBee通信模块可以为cc2530芯片或cc2538芯片，图7所示的网关还包括图7中未示出的串口转RS485接口，便于RS485与ZigBee通信模块之间的连接。有线与无线混合方案优点是结合有线方式的可靠性与无线方式的便捷性等不同特点来实现整个网络性能的最优设计。
以上方案中，采用RS485或电力载波的有线方案时，具有技术成熟，可靠性高等特点。采用ZigBee无线通讯方案，太阳能组件接线盒与网关组网时施工方便，不需额外增加线缆，还可以根据项目实际情况选择组合方案，有些项目为了美观需要把太阳能组件接线盒与太阳能组件分开，便于将太阳能组件接线盒隐藏在太阳能组件的金属框架中，这种安装方式会将无线信号屏蔽，故需要采用RS485或电力载波的有线方案，将线缆放在框架中既不影响美观又能实现 可靠的通讯。
在具体应用中，可以采用CAN总线来替代RS485或电力载波的有线方案，在实施例中提到的组网规模和距离范围内CAN总线方案均可以实现上述的通讯功能，其主要难点在软件的实现和硬件成本上比RS485略显劣势。
在具体应用中，可以采用蓝牙mesh组网来替代ZigBee组网方案，这种组网方案在组网数量和距离方面都不差于不加功率放大器的ZigBee组网方案。在网关与中控器的无线通讯可采用433MHz的无线通讯技术，这种通讯距离可以达到几百米，传输速率一般也不会低于LORA和NB-IoT的传输速率，缺点主要是在功耗方面要高于这两种无线通讯技术。

在一示例性实施例中，当状态检测数据包括温度数据、电压数据和电流数据时，只要温度数据、电压数据和电流数据任一个异常，都会生成关断控制信号。
如图9所示，本公开提供另一种太阳能组件控制方法，该方法的执行主体为第一示例性实施例涉及的太阳能组件接线盒，该方法可包括步骤901至步骤904：

1001、无线接收远程关断控制指令；
1002、在无线接收到远程关断控制指令后，生成所述关断控制信号。
在一示例性实施例中，步骤1002生成所述关断控制信号后，执行步骤904。
在一示例性实施例中，电源模块收到步骤1002和步骤903生成的任一关断控制信号，都会调整输出电压处于所述低电压范围。
在一示例性实施例中，步骤902中比较所述状态检测数据与预设状态阈值之间的大小；以及步骤903中在所述状态检测数据大于预设状态阈值后，生成关断控制信号，具体实现为如下步骤：
所述状态检测数据为温度数据，比较所述温度数据与预设温度 阈值之间的大小；如果所述温度数据大于所述预设温度阈值，则生成关断控制信号；
和/或

和/或

在一示例性实施例中，所述低电压范围为0V至24V。
以上示例性实施例公开的太阳能组件控制方法由第一示例性实施例涉及的太阳能组件接线盒来执行，为避免重复，具体说明及效果参见第一示例性实施例，在此不再赘述。
