Abstract
To achieve intelligent measuring,analysis,and feedback of ship attitude during the ship loading process,A ship berthing status monitoring system based on multi-source attitude detection was proposed by comparing and analyzing lots of monitoring methods adopted in bulk&general cargo ports during the ship loading process.Firstly,an accelerometer was used to detect the gravity direction and acceleration of an object,and then,the attitude data of pitch and roll in an initial stationary state was obtained through the gravity acceleration.Secondly,unified-coordinates-based data integration led to a complete relative motion so that attitude measuring data might assist ship loader in real-time ship loading correction.Finally,a 3D model system synchronizing ship attitude data showed different states corresponding to the data output and display of ship attitude under different threshold values,which verified the applicability of the monitoring method for ship berthing status.关键词
