Intelligent ship berthing assistance system and method

Abstract

The invention relates to the field of ship navigation safety, in particular to an intelligent ship berthing assistance system and method based on various sensors. According to the method, the intelligent ship berthing assistance system formed by an information real-time acquisition subsystem (1), a data real-time processing subsystem (2) and an information real-time issue subsystem (3) is adopted, data such as three-dimensional laser-point cloud, video images and environment parameters are acquired in real time through the information real-time acquisition subsystem (1), data real-time processing is carried out through the data real-time processing subsystem (2), the real-time ship distance, the berthing speed, the berthing angle, a wharf and ship three-dimensional model, the video images, the environment parameters, berthing suggestions, warning information and the like needed by ship berthing are acquired and are then issued to a user terminal through the information real-time issue subsystem (3), and therefore intelligent ship berthing assistance is achieved. The intelligent ship berthing assistance system and method are suitable for all sizes of berths and all types of ships and effectively solve the problems of limitation and simplicity of various other existing methods and systems.

Description

technical field [0001] The invention relates to the field of ship navigation safety, in particular to an intelligent ship berthing assistance system and method based on various sensors. Background technique [0002] For large ships and ships with dangerous goods, safe access to waterways and berthing is particularly important. When a large ship is berthing, it will be affected by complex hydrometeorological factors such as wind speed, wind direction, current speed, and flow direction, which will cause the ship to dock too fast or at an excessive angle, which will cause safety accidents such as ships hitting dock facilities and loading and unloading equipment. Huge economic losses, and even casualties may occur. [0003] The early berthing of ships mainly relied on the experience of the captain and pilot. The control of speed and angle during berthing was greatly affected by human factors, and the reliability was poor. Therefore, in order to ensure the safety of navigation,...

AI Technical Summary

Problems solved by technology

These berthing systems are all based on the principle of speed measurement, that is, to measure the speed of the ship when it is berthing. There are more or less problems: the sonar berthing instrument has a short working distance of only 200 meters, and it is easy to produce scattering, refraction, Phenomena such as emission, the measurement accuracy is poor; the infrared-based berthing assistance system is to install infrared detectors on the wharf to measure the distance between the ship and the wharf, and display the dynamic data of the ship through the large display screen installed on the wharf
