Ship profile scanning system

1. Feature introduction

The ship profile scanning system uses a laser scanner to measure the contour of the ship, calculate and set the safety protection area. Through communication with the PLC of the quay crane, the spreader and trolley can be intelligently decelerated to improve the safety protection of the quay crane operation, and the data of the ship type and box area can be collected and provided to the PLC to support remote control operation.

2. Technical indicators

（1）System initialization time：≤120s
（2）Scan and compute time：<200ms
（3）Measuring distance：>=80m (10% albedo)
（4）Measuring accuracy：±10cm
（5）The reserved height of the protected area：±80cm

3. System features

（1） When the container operation is carried out on the quay crane, the system uses a laser scanner to automatically detect the hull contour information under the quay crane girder in real time.
（2）By controlling the movement of the trolley and the lifting operation of the spreader, the intelligent deceleration and anti-collision protection of the spreader in the direction of the trolley and the lifting direction are realized, so as to avoid the collision accident between the spreader and the spreader lifting the container and the stacked container on the ship or the bilge and the side of the ship.
（3）Through the scanning of two trolley directions, the laser scans the contour of the double 20-foot container to realize the collision prevention of the double container operation.
（4）Scan the contour information of adjacent shells by scanning the direction scanning laser of the , control the movement of the trolley, and realize the anti-collision protection of adjacent shells.
（5）Control the movement of the crane according to the data of the hull and container area scanned by the laser, realize the anti-collision protection in the direction of the crane, and avoid the collision accident between the spreader and the container under the spreader and the stacked container or bilge and the side of the ship
