The invention relates to the field of ship detection, in particular to an automatic ship drainage detection system, which is provided with a sensor group comprising an inertial sensor arranged in a cabin and used for detecting the swinging amplitude and the swinging direction of the cabin and vibration sensors arranged at a plurality of positions of a pipeline at intervals and used for detecting vibration signals; the interference tendency determiner is used for calculating a noise interference characterization coefficient based on the cabin shaking amplitude and the density of the pipelines in the different areas so as to divide the noise interference tendencies of the pipelines in the different areas; the data filter is used for adaptively screening data acquired by the vibration sensor arranged on the regional pipeline based on the noise interference tendency of the regional pipeline; the early warning device is used for converting the screened vibration signals into frequency domain vibration signals, and whether early warning signals are sent out or not is judged on the basis of signal amplitudes in different frequency domain sections.By detecting the influence of environmental factors on the ship body in the drainage process, an alarm is given out in time for abnormal conditions, and the drainage stability and safety are guaranteed.
本发明涉及船舶检测领域,尤其涉及一种船舶排水自动检测系统,本发明设置传感器组包括设置于船舱用以检测船舱晃动幅度以及晃动方向的惯性传感器以及间隔设置在管道若干位置上用以检测振动信号的振动传感器;干扰倾向判定器用以基于船舱晃动幅度以及不同区域管道的密集度计算噪声干扰表征系数,以划分不同区域管道的噪声干扰倾向;数据筛选器用以基于区域管道的噪声干扰倾向,对区域管道上所设置振动传感器所采集的数据进行适应性地筛选;预警器用以将筛选出的振动信号转化为频域振动信号,基于不同频域段内的信号幅值判定是否发出预警信号,本发明通过检测排水过程中环境因素对船体的影响,对异常情况及时报警,保证排水的平稳度以及安全性。
