摘　　要：针对继电器失效误判断问题,提出在继电器电寿命试验中,引入触点状态(接通、断开)识别的图像处理系统,以提高对试品失效类型判断的可靠性。介绍了触点状态识别的图像处理系统硬件组成,阐述了在YCBCR彩色空间下,进行触点以及触点状态识别的算法,并论述了该系统与传统电寿命试验设备相结合,判断继电器失效类型的方法,以达到在继电器失效时,做出辅助判断的目的。To avoid the misjudgment of relay failure,the paper presents the image processing system that introduces state（switched-on or switched-off） recognition of contact in the relay electrical life test to improve the reliability in judging types of relay failure.It introduces the hardware structure of the image processing system based on state recognition of contact,describes the recognition algorithm of contact and its state in YCBCR color space,and discusses the way of judging relay failure types combining the system with traditional electrical test device for aided judgment when relay is failed.
