Embodiment Construction

[0017] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0018] See figure 1 , figure 2 ,, a method for using a bridge anti-collision active defense system in a specific embodiment, including a bridge anti-collision active defense system, the bridge anti-collision active defense system includes a pier active anti-collision control part and a ship-borne part, and the ship-borne Some of them include marine radar, ARPA (Automatic Radar Plotter) and shipboard AIS equipment on board. Shipboard AIS equipment is usually integrated with ECDIS (Electronic Chart Equipment) for display. The shipboard part can also include machine vision systems to increase Video monitoring; the active anti-collision control part of the pier includes several radar transponders, radar reflectors and a central control computer for data processing and control that can be installed on the bridge or pier, an...

Abstract

The invention relates to a use method of a bridge anti-collision active defense system. The 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, and the central control computer is in signal connection with the AIS virtual navigation mark unit and the alarm unit; the use method comprises a grading early warning method and a false alarm prevention method. The graded early warning method comprises the steps that early warning ranges are divided according to the distance from a ship to a bridge in the water flowing direction, and different early warning modes are adopted in different early warning ranges to distinguish the emergency degree of early warning; the false alarm prevention method comprises the following steps: performing judging according to the attitude and speed of the ship in the early warning range, and if the ship is a special ship, not triggering the early warning mode in the graded early warning method. According to the invention, the early warning reliability is improved through AIS and radar; and the early warning range is divided and special ships are distinguished, so that efficient early warning can be ensured.

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 method for using 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-collision is to take measures to ...
