航天继电器微粒碰撞噪声自动检测系统的研究

针对以往多余物微粒碰撞噪声检测(PIND)系统中存在检测精度低、误判和漏判率高等问题,提出一种基于小波分析的多余物自动检测方法,研制了具有自主知识产权的航天继电器微粒碰撞噪声检测系统.实验结果表明,检测系统运行稳定、性能优异、用户界面友好,各项技术指标均优于国际同类产品,亦适用于其他军用电子元器件的多余物检测.

Research on Particle Impact Noise Auto Detecting System for Aerospace Relay

Due to traditional particle impact noise detection(PIND)system for remainder detection with low precision,high leave out rate and wrong judgment rate,a remainder auto detecting method based on wavelet analysis was preseated.A PIND system for space relay with self-owned intellectual property rights was designed.The experiment result indicates that the detecting system runs stably with friendly human interface,the performance is excellent and the main indexes excelled the same type product in the world.The system is also suitable for remainder detecting for other military electronic components.
