基于AIS的船舶避碰系统研究

Research on Ship Collision-avoidance Based on AIS

船舶自动识别系统AIS的诞生为船舶避碰提供了一种新方法,研究了船舶自动识别系统AIS的关键技术及其组成,设计了基于AIS的船舶避碰系统。该系统对AIS等设备采集的数据进行变换与接收,以DSP为信息处理和控制元件,采用FPGA以解决多接口的问题。AIS技术的引入,使船舶碰撞危险系数的计算更为精确,船舶与船舶之间、船舶与岸台之间的通信更加迅速。

Automatic Identification System （AIS） provides a new way of ship- collision. The core technology and composition of AIS are researched, the collision - avoidance system based on AIS is designed. The system covers the data transform and collection by AIS. The collision - avoidance system using DSP chip for treatment and control of information and the design of multiple ports is solved by FPGA. Due to the appliance of AIS,the risk of ship collision coefficient calculation is more precise and the communication between ship and ship, ship and shore are more rapidly.
