Abstract

The invention provides a UWB-based ship berthing assist method and system. The system includes a data acquisition platform, a data processing platform and a data display platform. The method includes a first step, in which a data acquisition module acquires UWM node information in real time and transmits the information to a data processing module; a second step, in which the data processing module processes the information transmitted in the first step and obtains the contours of a dock and a ship, the distance from the ship to the dock, the angle and relative speed and early warning information; a third step, in which a data storage module saves the above information in real time and meanwhile transmits the information through the data transmission module to the data display platform so that an external client can assist the ship in berthing at the dock; and the first to third steps are repeated for data real-time update to achieve dock berthing assist function. The invention assists the ship in berthing through UWB positioning technology and network technology, and has the advantages of low cost, wide coverage, high positioning precision and small impact of environmental factors.

Description

technical field [0001] The present invention relates to the technical field of ship berthing positioning, in particular to a UWB-based ship berthing assistance method and system. Background technique [0002] When the ship is berthing, if the angle and speed of the ship cannot be well controlled, it is very easy to cause accidents such as the hull touching the dock by mistake. The early berthing of ships mainly relied on manual experience, and the reliability was relatively poor. With the installation of various speedometers in some developed ports around the world, it assists various large ships to berth safely. However, these speed measuring devices basically adopt the principle of shore-based measurement, which is not suitable for small ships and small docks. [0003] There are certain deficiencies in some ship berthing auxiliary systems currently in use. For example, devices using the principle of sound waves and lasers are greatly affected by the environment such as ...
