摘　　要：对船舶主机的健康实时监测问题进行研究,突破传统的机舱综合报警监测系统(AMS)监测模式采用连续时间的多维数据,以马氏距离、孤立森林、密度聚类算法(DBSCAN)、单类支持向量机(OCSVM)4类异常检测算法对实船数据进行实验验证,基于每个算法在各个场景下的实际表现,通过与出现异常的数据点进行对照,4类算法在异常检测的灵敏度、误判、遗漏指标方面均有较好的表现。The real-time monitoring of the health of the ship main engine is studied,and the traditional AMS alarm system monitoring method is made by using multi-dimensional data of continuous time.The real ship data is experimented by four types of anomaly detection algorithms:Mahalanobis distance,Isolation Forest,DBSCAN,and OCSVM,and the actual performance of each algorithm in each scenario is obtained.By comparing with the actual abnormal data points,the four types of algorithms have good performance in the sensitivity,false judgment and missing indicators of anomaly detection.
