Active collision avoidance system and method for ship-borne navigation in the inland river bridge area

Abstract

The invention provides a method for inland river bridge zone shipborne sailing active collision prevention. The method comprises the steps of collecting hydrological information, meteorological information and ship information of nearby ships and the ship, automatically updating river map information on line, and performing data storage; forecasting tracks of the ship and other ships according to obtained track information of the ship and other ships by combination with the real-time hydrological information and the meteorological information, and obtaining track information of every ship; calculating the nearest meeting distance and the nearest meeting time of the ship and a target object according to the obtained track information; and giving collision accident pre-warning and active collision prevention suggestions according to the nearest meeting distance and the nearest meeting time of the ship and the target object. According to the method, by predicating ship sailing situations, the shortcoming that an existing ship assistance navigation device cannot accurately obtain the position of the target object, and the nearest meeting distance and the reaching of the nearest meeting distance cannot be pre-judged more accurately is overcome.

Description

technical field [0001] The patent of the present invention relates to a ship-borne navigation collision avoidance system and a collision avoidance method. Background technique [0002] As the link of land transportation between the two sides of the river, the bridge's status and role are self-evident. With the rapid development of my country's transportation industry, more and more bridges are being built, and the bridges are getting denser and denser. Before the 1990s, there were only 7 bridges on the Yangtze River. By this century, there were more than 60 Yangtze River Bridges built or under construction from the Yibin section of the Yangtze River to the Yangtze Estuary. On the other hand, due to the limitation of the bridge to the navigation environment, it has gradually become the navigation bottleneck of the inland waterway. Once the ship-bridge collision occurs in the water area of ​​the bridge area, it will cause losses to the bridge. While cutting off the road traf...
