摘　　要：针对船舶压载水系统工作环境恶劣,相关设备易发生故障且传统人工故障检测方法耗时长、误判率高的问题,提出一种基于随机森林算法的船舶压载水系统故障诊断方法。以某大型集装箱船模拟器压载水系统的5种运行状态的180组运行数据为样本,随机选取150组数据作为训练集,30组数据作为测试集,使用MATLAB软件进行模型搭建。结果表明,模型的总体准确率达到95%以上,可以较为准确地对船舶压载水系统的常见故障进行判别。Aiming at the problem that the working environment of ship ballast water system is poor,the related equipment is prone to failure,and the traditional manual fault detection method is time-consuming and has a high misjudgment rate,a fault diagnosis method of ship ballast water system based on random forest algorithm is proposed.Taking 180 groups of operation data of ballast water system in five operation states of a large container ship simulator as the most sample,150 groups of data are randomly selected as the training set,and 30 groups of data are selected as the test set.The mathematical software MATLAB is used to build the model.The results show that the overall accuracy of the model is more than 95%,which can accurately identify the common faults of ship ballast water system.
