摘　　要：核动力系统内部存在高温高压蒸汽,一旦发生泄漏,轻则导致系统功能丧失,重则造成人员伤亡,因此开展核动力系统蒸汽泄漏检测工作迫在眉睫。当前,蒸汽泄漏主要通过压力表进行检测,若系统压力较高时出现微小泄漏,其压力减小量不足以引起运行人员重视,以致于无法及时发现蒸汽泄漏,因此该检测方法存在一定弊端。本文引入计算机视觉技术对核动力系统进行监测,采用帧差法对蒸汽泄漏进行检测,结果表明,该方法针对帧率小于26的蒸汽泄漏检测视频,在泄漏初期就能有效检测出蒸汽泄漏,并进行预警。该方法的提出为核动力系统蒸汽泄漏检测提供了一种新思路且能够有效应用于工程领域,同时也为其它领域高温高压介质的泄漏检测提供参考。The nuclear power system contains high-temperature and high-pressure steam inside.Once steam leakage occurs,it can lead to a loss of system function,and even cause casualties in severe cases.Therefore,it is urgent to carry out steam leakage detection in nuclear power system.At present,steam leakage is mainly detected through pressure gauges.If there is a small leakage when the system pressure is high,but the pressure reduction is not enough to attract the attention of operators,it will lead to the failure to detect steam leakage in a timely manner.Therefore,this detection method has certain drawbacks.This article introduces computer vision technology to monitor the nuclear power system and uses frame difference method to detect steam leakage in the high-temperature and high-pressure circuit system.The results show that this method can effectively detect the steam leakage in the early stage and give an early warning for the steam leakage detection video with the frame rate less than 26.This method provides a new idea for steam leakage detection of nuclear power system and can be effectively applied to engineering field,and also provides reference for leakage detection of high-temperature and high-pressure media in other fields.
