卫星太阳能电池阵破损自动检测系统的研究

介绍了国内首次研制的卫星太阳能电池阵破损自动检测系统的检测原理、系统结构与设计及现场试用结果。系统采用专用照明系统,电池阵列经光学系统清晰成像至CCD传感器上,经信号放大、A/D转换后输入计算机管理和控制系统。图像传感探头自动扫描整块电池板,并由距离传感器控制,始终保持采集图像清晰。利用特有的系统控制和检测软件,处理每幅电池图像信息,检测结果通过列表形式给出损伤电池的位置、破损类型、破损度等参数。现场试验结果表明:该系统的检出率达98.5%以上,检测速度为每分钟20片电池,达到了快速、高精度、自动化检测太阳能电池阵的使用要求。

Automatic damage detection system for satellite solar array

The automatic damage detection system for a satellite solar array was firstly developed in China,and its detection theory,structure and design of detection system and the results of on-site trial were introduced.By using a unique lighting system,the image of the salar array was focused clearly onto a CCD sensor via an optical system,then the signals were multiamplified and A/D converted to store in a computer system.An imaging probe automatically scans the whole array and keeps the image clear through the c...
