Graded early warning method based on bridge anti-collision active defense system

Abstract

The invention relates to a graded early warning method based on a bridge anti-collision active defense system, the method is implemented based on the bridge anti-collision active defense system, the bridge anti-collision active defense system comprises a bridge pier active anti-collision control part and a shipborne part, and the shipborne part comprises a marine radar carried on a ship, an ARPA automatic radar plotter and a shipborne AIS device; the bridge pier active anti-collision control part comprises a plurality of radar transponders and a central control computer used for data processing control, and the central control computer is in signal connection with the AIS virtual navigation mark unit and the alarm unit; the early warning range is divided according to the distance between the ship and the bridge in the water flowing direction, different distances correspond to different early warning ranges, and different early warning modes are adopted for the ships in the different early warning ranges to distinguish the emergency degree of early warning. According to the grading early warning method, the early warning reliability is improved in an AIS and radar mode; by reasonably dividing the early warning range and adopting different early warning modes, the emergency degree of early warning can be effectively reflected.

Description

technical field [0001] The invention belongs to the technical field of anti-collision systems in traffic control systems, and in particular relates to a hierarchical early warning method based on a bridge anti-collision active defense system. Background technique [0002] With the rapid development of the river-sea shipping industry, the volume of shipping continues to increase, the tonnage and speed of ships continue to increase, and a large number of river-sea bridges are also being built, resulting in increasingly prominent contradictions between ships and bridges, frequent collision accidents, and serious consequences. Aiming at the ship collision accident, after a lot of theory and practice, after continuous development, there are two main methods of bridge collision avoidance: passive collision avoidance method and active collision avoidance method. Passive anti-collision is to absorb energy by installing some anti-collision devices on bridge piers; active anti-collisi...
