光伏行业的EL(Electroluminescent)检测是指：通过给光伏板供电，利用晶体硅的电致发光原理，利用近红外相机拍摄电池组件的近红外图像，获取并判定电池组件的内部缺陷，如隐裂、碎片、虚焊、断栅以及不同转换效率单片电池异常现象等。
目前，现有技术中的EL检测一般需要将近红外相机固定在一个三角支架上，每检测一块光伏板，需要移动/调整三脚架的位置，此外，由于大多数近红外相机是基于可见光相机改造的，对于近红外波段的响应能力并不是非常高，进而需要长时间(秒级)曝光来拍摄每一块光伏板电池组件的内部缺陷，因此，需要固定住三脚架不能动。
然而，现有技术中的EL检测方式，一般情况下需要多个工作人员协同作业，操作复杂，并且由于每检测一块光伏板时，即需要移动/调整三脚架的位置，因此，也无法做到短时间内对整个电站进行全检操作，从而降低了EL检测的质量和效率。

具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，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。
除非另有定义，本文所使用的所有的技术和科学术语与属于本发明的技术领域的技术人员通常理解的含义相同。本文中在本发明的说明书中所使用的术语只是为了描述具体的实施例的目的，不是旨在于限制本发明。本文所使用的术语“及/或”包括一个或多个相关的所列项目的任意的和所有的组合。
在本发明中，术语“安装”、“连接”、“固定”等术语均应广义理解，例如，“连接”可以是固定连接，也可以是可拆卸连接，或一体地连接。对 于本领域的普通技术人员而言，可以根据具体情况理解上述术语在本发明中的具体含义。
在本发明的描述中，需要理解的是，术语“中心”、“纵向”、“横向”、“长度”、“宽度”、“厚度”、“上”、“下”、“前”、“后”、“左”、“右”、“竖直”、“水平”、“顶”、“底”“内”、“外”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本发明和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本发明的限制。
下面结合附图，对本发明的一些实施方式作详细说明。在不冲突的情况下，下述的实施例及实施例中的特性可以相互组合。
图1为本发明一实施例提供的一种光伏组件的EL检测设备中手持云台1的结构示意图一；参考附图1所示，本实施例提供了一种光伏组件的EL检测设备，该EL检测设备可以实现在短时间内对整个电站进行全检操作，从而有效地提高了EL检测的质量和效率，具体的，该EL检测设备可以包括：手持云台1和红外相机(图中未示出)，其中，手持云台1包括：云台11及支撑云台11的手柄12，该手柄12为用户进行握持的部分，可以包括控制按钮121，以便于对云台11进行操作；而云台11可以包括多个转轴机构，转轴机构包括转轴部111和与转轴部111连接的连接支架112，连接支架112通过转轴部111与手柄12活动连接，红外相机通过连接支架112设置于云台11上；手持云台1与红外相机通信连接，以获取红外相机所拍摄的图像信息，并基于图像信息对光伏组件进行EL检测。本实施例中，所述红外相机可以为近红外相机，包括专用近红外相机(具有较短的曝光时间)。
其中，为了便于将红外相机稳定地设置于云台11上，在云台11上可以设置有用于夹持红外相机的夹持部13，夹持部13通过连接支架112连接在云台11上。此时，夹持部13可以与连接支架112固定连接或者锁定连接，具体的，固定连接可以通过连接件(螺钉、螺栓、螺柱或者粘结剂)使得夹持部13与连接支架112相连接，或者，夹持部13与连接支架112为一体成型结构；而锁定连接可以是指：首先，夹持部13可以与连接支架112进行相对运动或活动，此时，夹持部13与连接支架112为活动连接状态，而当将夹持部13或夹持部13上的红外相机调整到某一目标位置之后，可以对处于该 位置的夹持部13与连接支架112之间进行锁定，使得夹持部13与连接支架112之间保持不动，此时，夹持部13与连接支架112为固定连接状态；可以理解的是，该夹持部13的具体形状结构可以与红外相机的形状结构相适配，该夹持部13还可以夹持不同尺寸的红外相机。
另外，本实施例对于转轴机构的具体个数不做限定，本领域技术人员可以根据具体的设计需求进行设置，例如，可以将转轴机构的个数设置为2个、3个、4个或者更多；当转轴机构的个数为两个时，两个转轴机构可以使得手持云台1上的红外相机实现在两个不同方向上的自由运动(绕X轴方向和Y轴方向、绕X轴方向和Z轴方向或者绕Y轴方向和Z轴方向的转动)，此时的手持云台1可以为两轴云台11；当将转轴机构的个数设置为3个时，3个转轴机构可以使得手持云台1上的红外相机实现在3个不同方向上的自由运动(绕X轴、Y轴、X轴的转动)，此时的手持云台1可以为三轴云台11；当将转轴机构的个数设置为4个时，4个转轴机构可以使得手持云台1上的红外相机实现在4个不同方向上的自由运动(绕X轴、Y轴、X轴的转动及沿X、Y或Z轴任一个轴的平动)，此时的手持云台1可以为四轴云台11。
另外，本实施例中对于转轴部111和连接支架112的具体个数不做限定，本领域技术人员可以根据转轴机构的具体个数进行设置，例如：附图1所示，该图中的转轴机构的个数为3个，因此，转轴机构所包括的转轴部111和连接支架112均为3个，以使得手持云台1上的红外相机可以实现在3个不同方向上的自由运动；附图3-4所示，该图中的转轴机构的个数为两个，因此，转轴机构所包括的转轴部111和连接支架112均为两个，以使得手持云台1上的红外相机可以实现在2个不同方向上的自由运动；可以理解的是，转轴部111和连接支架112的具体个数可以随转轴机构设置的个数而进行变化。
此外，由于接支架112与手柄12通过转轴部111可转动地连接，具体的，转轴部111可以包括电机，所述连接支架112和手柄分别连接于电机的定子和转子，从而通过电机的转动，可以驱动所述连接支架112与手柄12之间的相对转动；而红外相机通过连接支架112设置于云台11上，因此，通过调节转轴部111的转动量以及转动速度，可以调节设置于云台11上的红外相机的朝向，如水平朝向，以便于实现调整红外相机与光伏组件的相对位置；而在调整的过程中，一般情况下只需要一个工作人员调节，如操作手柄12上的控 制按钮121，即可完成，并不需要多个工作人员协同工作，操作比较简单。
此外，通过包括多个转轴部111及连接支架112的云台11支撑红外相机，由于多个连接支架112可绕多个方向相对转动，故可有效减少从手柄12传递至红外相机的震动，可起到防抖效果，保证红外相机的稳定。
具体操作时，通过对连接支架112和手柄12之间相对转动角度的调节，可以快速实现对红外相机所处的朝向进行调节，使得红外相机处于不同的检测位置，而后通过红外相机可以对不同检测位置的检测部件进行拍摄，获取到检测部件的图像信息，红外相机内部可以设置有信息发送装置，该信息发送装置可以为有线装置或无线装置，进一步的，红外相机可以通过信息发送装置主动地将所检测的图像信息发送至手持云台1，此时，手持云台1可以被动地接收到图像信息；作为另一种可实现的方式，手持云台1也可以主动地获取到图像信息，具体的，在手持云台1内部设置有监测装置，该监测装置可以监测红外相机的工作状态，当监测到红外相机进行拍照操作之后，手持云台1会主动向红外相机发送获取图像信息请求，使得红外相机可以根据获取图像信息请求将拍照所获取的图像信息发送至手持云台1；进一步的，在手持云台1接收到图像信息之后，可以对图像信息分析处理，从而实现对检测部件(光伏组件)的EL检测。
本实施例提供的光伏组件的EL检测设备，通过将红外相机设置于手持云台1上，而手持云台1上的转轴机构包括转轴部111和与转轴部111连接的连接支架112，红外相机通过连接支架112设置于云台11上，因此，通过调节转轴部111的转动量以及转动速度，可以调节设置于云台11上的红外相机的朝向，从而实现了调整红外相机与光伏组件的相对位置，使得红外相机可以处于不同的检测位置，调节操作简单，便于实现在短时间内对整个电站进行全检操作，有效地提高了EL检测效率，进一步保证了该EL检测设备的实用性，有利于市场的推广与应用。
图3为本发明另一实施例提供的一种光伏组件的EL检测设备中手持云台1的结构示意图一；图4为本发明另一实施例提供的一种光伏组件的EL检测设备中手持云台1的结构示意图二；在上述实施例的基础上，继续参考附图3-4可知，本实施例中EL检测设备中的云台11可以为两轴云台或三轴云台，当云台11为两轴云台时，转轴机构可以包括：用于带动红外相机相对于手柄 12进行水平旋转运动的平移轴机构113和与平移轴机构113相连接的横滚轴机构114，横滚轴机构114用于带动红外相机相对于手柄12进行横滚运动。
其中，平移轴机构113可以包括与手柄12相连接的第一转轴部1131和与第一转轴部1131连接的第一连接支架1132，第一连接支架1132与横滚轴机构114相连接；而横滚轴机构114可以包括与第一连接支架1132相连接的第二转轴部1141和与第二转轴部1141连接的第二连接支架1142。此时，红外相机可以通过夹持部13设置于第二连接支架1142上。并且，本实施例中的连接支架112可以通过转轴部111与相邻的元件，如连接支架112和/或手柄12可转动地连接，具体地，如所述第二连接支架1142通过第二转轴部1141与第一连接支架1132可转动地连接。此外，第一连接支架1132与所述手柄12可通过第一转轴部1131可转动地连接。
为了便于说明，参考附图3-4可知，建立XYZ坐标系，具体应用时，当利用该EL检测设备光伏组件进行EL检测时，光伏组件所处的位置与EL检测设备中的红外相机的位置不符合规范要求，此时，需要对红外相机所处的位置进行调节；具体的，当需要对红外相机在水平方向上进行位置调节时，可以通过平移轴机构113来实现，具体的，通过调节第一转轴部1131的转动量和/或转动速度，可以调节第一连接支架1132与手柄12的相对转动角度，此时，可以使得红外相机围绕手柄12进行转动操作(需要注意的是，此时描述的是第一连接支架1132相对手柄12的转动，而红外相机设置于第二连接支架1142上，第二连接支架1142与第一连接支架1132相连接，其会因第二连接支架1142的带动而进行运动，故应该是红外相机相对手柄12的转动)，进而可以对红外相机实现在水平方向(即绕Z轴)的位置调节。当需要对红外相机在横滚方向(如图中所示，绕Y轴)上进行位置调节时，可以通过横滚轴机构114实现，具体的，通过调节第二转轴部1141第二连接支架1142与第一连接支架1132的相对转动角度，此时，可以使得红外相机围绕第一连接支架1132进行转动操作(需要注意的是，此时描述的是第二连接支架1142相对第一连接支架1132的转动，而红外相机设置于第二连接支架1142上，其会因第二连接支架1142的带动而进行运动，故应该是红外相机相对第一连接支架1132的转动)，进而可以对红外相机实现在横滚方向上的位置调节。当需要对红外相机在水平方向和横滚方向上进行位置调节时，可以按照上述 的实现方式，先进行水平方向上的位置调节，而后进行横滚方向上的位置调节；或者，也可以先进行横滚方向上的位置调节，而后再进行水平方向上的位置调节；或者，同时进行水平方向和横滚方向上的位置调节均可。
本实施例中的EL检测设备，通过将云台11中的转轴机构包括平移轴机构113和横滚轴机构114，其中，平移轴机构113可以带动红外相机相对于手柄12进行水平旋转运动，从而可以对红外相机实现在水平方向上的位置调节；而横滚轴机构114可以带动红外相机相对于手柄12进行横滚运动，可以对红外相机实现在横滚方向上的位置调节，便于红外相机对处于不同位置的光伏组件进行拍照，进一步提高了该EL检测设备使用的方便可靠性。
图2为本发明一实施例提供的一种光伏组件的EL检测设备中手持云台1的结构示意图二；在上述实施例的基础上，继续参考附图2可知，作为另一种可实现的方式，本实施例中EL检测设备中的云台11可以为三轴云台11，具体的，当云台11为三轴云台11时，除了包括上述的平移轴机构113和横滚轴机构114之外，该转轴机构还可以包括与横滚轴机构114相连接的俯仰轴机构115，红外相机通过夹持部13设置于俯仰轴机构115上，俯仰轴机构115用于带动红外相机相对于手柄12进行翻转运动。
其中，俯仰轴机构115可以包括与第二连接支架1142相连接的第三转轴部1151和与第三转轴部1151连接的第三连接支架1152。此时，红外相机可以通过夹持部13设置于第三连接支架1152上。
具体应用时，参考附图2可知，当利用该EL检测设备光伏组件进行EL检测时，光伏组件所处的位置与EL检测设备中的红外相机的位置不符合规范要求，此时，需要对红外相机的位置进行调节；具体的，当需要对红外相机在水平方向(即绕Z轴)和/或横滚方向(即绕Y轴)上进行位置调节时，具体的调节方式和实现过程可参考上述陈述内容，在此不再赘述；而当需要对红外相机在俯仰方向(即绕X轴))上进行位置调节时，可以通过俯仰轴机构115实现，具体的，通过调节第三转轴部1151的转动量和/或转动速度，可以调节第三连接支架1152与第二连接支架1142的相对转动角度，此时，可以使得红外相机围绕第二连接支架1142进行转动操作(需要注意的是，此时描述的是第三连接支架1152相对第二连接支架1142的转动，而红外相机设置于第三连接支架1152上，其会因第三连接支架1152的带动而进行运动， 故应该是红外相机相对第二连接支架1142的转动)，进而可以对红外相机实现在俯仰方向上的位置调节。需要注意的是，当需要对红外相机在水平方向(即绕Z轴){横滚方向(即绕Y轴)}和俯仰方向(即绕X轴)上进行位置调节时，可以按照上述的实现方式，先进行水平方向(横滚方向)上的位置调节，而后进行俯仰方向上的位置调节；或者，也可以先进行俯仰方向上的位置调节，而后再进行水平方向(横滚方向)上的位置调节；或者，同时进行水平方向(横滚方向)和俯仰方向上的位置调节均可。
同理的，当需要对红外相机在水平方向(即绕Z轴)、横滚方向(即绕Y轴)以及俯仰方向(即绕X轴)上进行位置调节时，可以按照任意一个操作顺序实现上述方向上位置的调节，只要能够最终实现对红外相机在水平方向(即绕Z轴)、横滚方向(即绕Y轴)以及俯仰方向(即绕X轴)上进行位置调节即可，在此不再赘述。
本实施例提供的EL检测设备，通过将云台11设置为三轴云台，而红外相机可以设置于三轴云台上，具体操作时，只需要一个工作人员就可以进行EL检测，如通过操作手柄12上的控制按钮121即可实现，并且，工作人员可以对手持设备进行快速移动、调整，而且移动效率大大提高；同时，利用云台11的三轴防抖特性可以有效地保证红外相机的拍摄质量，具体的，三个转轴机构的转轴部111与连接支架112连接，可以有效地降低云台11传递到红外相机的抖动程度，从而保证了红外相机的拍摄质量和效率，同时，通过三个转轴机构可以灵活地调整红外相机所处的拍摄位置，便于对光伏组件的缺陷位置进行快速、有效拍照，大大地提高了检测的灵活性和效率。
图5为本发明又一实施例提供的一种光伏组件的EL检测设备中手持云台1的结构示意图；在上述实施例的基础上，继续参考附图2、5所示，作为另一种可实现的方式，本实施例中EL检测设备中的云台11还可以为四轴云台，具体的，该云台11除了可以包括上述的平移轴机构113、横滚轴机构114以及俯仰轴机构115，该手持云台1中的连接支架112还包括用于在垂直方向上进行减震的第四连接支架116，第一转轴部1131通过第四连接支架116与手柄12相连接。
其中，该第四连接支架116可以带动红外相机相对于手柄12在水平平面上进行水平运动，并且，该第四连接支架116的运动方向与第一转轴部1131 的轴向方向平行。具体的，可以通过调节第四连接支架116的长度来实现；对于第四连接支架116的具体形状结构不做限定，本领域技术人员可以根据其实现的功能作用对其进行设置，例如：该第四连接支架116可以包括支架主体和设置于支架主体上的滑动槽，第一转轴部1131设置于滑动槽内，并且滑动槽内设置有伸缩弹簧，通过控制伸缩弹簧的伸缩量可以调节第一转轴部1131与第四连接支架116的具体连接位置，从而实现调节红外相机相对于手柄12在水平平面上水平平动位置，此外，通过设置的伸缩弹簧和第四连接支架116的长度尺寸，可以在垂直方向上有效地减少手柄12传递到第一转轴部1131上的震荡程度，进一步保证了红外相机的拍摄质量；当然的，本领域技术人员还可以采用其他形状结构的第四连接支架116，只要能够实现上述功能效果即可，在此不再赘述。
通过设置的第四连接支架116，结合上述的平移轴机构113、横滚轴机构114以及俯仰轴机构115，不仅可以在垂直方向上进行降低手柄12传递至红外相机处的震动程度，并且还有效地提高了对红外相机所在位置进行调节的精确可靠性，进一步保证了该EL检测设备使用的稳定可靠性。通过可实现三个方向的转动以及一个方向的平动的云台，可有效减少传递至红外相机的震动，提高拍摄质量。
在上述任意一个实施例的基础上，继续参考附图1-5可知，为了进一步提高该EL检测设备使用的方便程度，本实施例中的手柄12上可以设置有用于控制红外相机进行工作的控制按钮121，控制按钮121通过云台11与红外相机通信连接。
