The Design And Implementation Of Fishing Vessel Integrated Navigation Information System

With the development of science,technology and maritime shipping industry,the integrated navigation system plays a vital role in the safe navigation of ships at sea.The integrated navigation system integrates Beidou,GPS,AIS,radar and other navigation information into the electronic chart computer.And the integrated navigation system combined with the functional modules such as real-time alarm monitoring and automatic collision avoidance,the integrated navigation system greatly reduces the risk of maritime accidents,reduces the manpower of seafarers at sea and improves the efficiency of ship navigation.At present,integrated navigation system is mainly used in large ships and oceangoing fishing vessels due to high cost.This paper mainly focuses on the navigation requirements of small and medium-sized fishing boats combined navigation information system,using Qt development tool and YIMAENC development components.The multisource navigation information receiving technology and ship collision avoidance technology are mainly studied.The integrated navigation system for small and medium-sized fishing boats is designed and realized,which has many functions,such as chart function,centralized display of navigation information,alarm monitoring,automatic collision avoidance decision,etc.The main contents of this paper are as follows :(1)Design the system scheme for the integrated navigation information of fishing boats.(2)The basic functions of integrated navigation information of fishing boats are designed and realized.(3)Study the automatic collision avoidance decision-making function of ships,and design and realize the automatic collision avoidance decision-making function of ships.(4)Functional test for the integrated navigation system of small and medium-sized fishing boats.
