本公开提供了一种识别调距桨故障的方法和装置,属于船舶推进装置领域。所述方法包括:采集待识别的调距桨的油液流量和桨叶角度,得到待识别的调距桨的油液流量在多个设定时间段内各个相邻时间点之间的第一变化量;根据调距桨的桨叶角度,获取第一故障的调距桨的油液流量的第二变化量;分别采用待识别的调距桨的油液流量在各个设定时间段内的第一变化量对应的第二变化量作为输入,分布在第一函数上的多个数值作为输出,训练第一支持向量机;分别将待识别的调距桨的油液流量在各个设定时间段内的第一变化量输入第一支持向量机;若第一支持向量机输出的多个数值都分布在第一函数上,则确定待识别的调距桨存在第一故障。本公开可确定调距桨故障。

    The invention provides a method and device for identifying the faults of a controllable-pitch propeller, and belongs to the field of ship propulsion devices. The method comprises the steps that: the oil flow and blade angle of a to-be-identified controllable-pitch propeller are collected, and the first variable quantity of the oil flow of the to-be-identified controllable-pitch propeller between every two adjacent time points within a plurality of set time periods is obtained; according to the blade angle of the controllable-pitch propeller, a second variable quantity of the oil flow of the controllable-pitch propeller with a first fault is obtained; a first support vector machine is trained with the second variable quantity corresponding to the first variable quantity of the oil flow of the to-be-identified controllable-pitch propeller in each set time period taken as an input and a plurality of numerical values distributed on a first function taken as an output; the first variable quantity of the oil flow of the to-be-identified controllable-pitch propeller in each set time period is input into the first support vector machine; and if the plurality of numerical values output by the first support vector machine are distributed on the first function, it is determined that the to-be-identified controllable-pitch propeller has the first fault. The method and device of the presentinvention can determine the fault of the controllable-pitch propeller.
