Abstract

The invention relates to a ship collision avoidance early-warning device which comprises a single-chip microcomputer controller, an input unit, a display unit, an execution unit, a communication unit, an alarm unit and a working signal light. The execution unit comprises a direct-current motor, a motor drive matched with the direct-current motor, a stepping motor, a motor drive matched with the stepping motor, two two-degree-of-freedom electrical platforms, and two laser range finders placed on the electrical platforms respectively. The invention further relates to an intelligent early-warning method of the ship collision avoidance early-warning device. According to the method, the distance between an obstacle in the horizontal direction and a ship and the height of a bridge ahead are detected, transmitted and displayed, early-warning against danger signals is carried out, and conversion of work systems in different modes can be achieved. The ship collision avoidance early-warning device can be installed in various types of ships, and is high in detection and early-warning precision and high in cost-performance ratio.

Description

technical field [0001] The invention relates to a ship collision avoidance early warning device and an intelligent early warning method thereof. Background technique [0002] With the large-scale development of ships, the number of ships is increasing rapidly, and water traffic accidents are also on the rise, especially the collision between ships and ships, ships and bridge piers, ships and cross-sea cables, the occurrence of such accidents, the loss is often is huge. [0003] At present, the devices used in the field of collision avoidance between ships at home and abroad mainly include automatic radar plotter (ARPA) and ship automatic identification system (AIS). Domestic and foreign measures for ship collision with bridges mainly focus on bridge anti-collision facilities (such as adding fences around bridge piers), which is a passive measure. There is no active ship collision avoidance device, and the cost of this measure is also extremely expensive . And the collisio...
