摘要
立足高港船闸航道实际情况,研究了一套过闸船舶吃水深度检测系统。利用多个超声波传感器扫描测距的方法,实现行进船舶的吃水检测。检测架连接2座警示浮筒安装于水下。采用动态压力补偿的方法解决浮筒摆动导致系统稳定性差及水下检测架弯曲变化导致系统测量精度低的问题。建立最小二乘支持向量机预测模型对异常检测数据进行处理,最终得到过闸船舶的吃水深度信息。本研究采用现场实测的方法对系统性能进行验证,结果表明,系统稳定有效,测量精度较高,满足高港船闸实际运管需求。
Based on the actual situation of Gaogang Ship Lock channel,a set of draft depth detection system for lockage ships is studied.The method of scanning distance measurement by multiple ultrasonic sensors is used to realize the draft detection of moving ships.The detection frame is connected to two warning buoys and is installed underwater.The dynamic pressure compensation method is used to solve the problem of poor stability of the system caused by the buoy swing and the low measurement accuracy of the system caused by the bending change of the underwater detection frame.The least squares support vector machine prediction model is established to process the anomaly detection data,and finally the draft depth information of the lockage ship is obtained.In this study,the performance of the system is verified by field measurement.The results show that the system is stable and effective,and the measurement accuracy is high,which meets the actual transportation management requirements of Gaogang Ship Lock.
