基于ACCESS数据库的光伏组件隐裂信息管理

PV MODULES HIDDEN CRACK INFORMATION MANAGEMENT BASED ON ACCESS DATABASE

隐性裂纹(下文简称“隐裂”)是导致光伏组件产生热斑现象的原因之一,通过对光伏组件进行隐裂检测,能有效避免光伏组件出现热斑现象。电致发光(EL)是检测光伏组件是否存在隐裂的有效方式,对存在隐裂的图片进行存储,可以用于分析隐裂的形态和成因。但由此产生的信息管理工作的工作量非常大,由于图片量大且隐裂形态相近,容易混淆。本文阐述了利用ACCESS数据库来管理光伏组件隐裂检测过程中产生的隐裂图片等信息,该方法可有效提高光伏组件检测工作的效率与精确度。

Hidden crack is one of the reasons for the hot spot phenomenon of PV modules.By detecting the hidden crack of PV modules,the hot spot phenomenon of PV modules can be effectively avoided.Electroluminescence(EL)is an effective way to detect whether there are hidden cracks in PV modules,storing the hidden crack pictures of PV modules to analyze the form and cause of the hidden cracks.But the resulting information management work is heavy,and due to the large amount of pictures and close images,they are easy to be confused.It is explained that by using the ACCESS database to manage the information such as the hidden crack pictures generated during the hidden cracking detection process of PV modules,this method effectively improves the efficiency and accuracy of the PV modules detection work.
