基于FPGA和ARM的船舶防撞系统设计

Design of marine collision avoidance system based on FPGA and ARM

研究设计了一种基于FPGA和ARM的船舶防碰撞告警设备。该设备主要应用在中小型船只上,与船上原有经济型航海雷达配合使用构成一个新系统。防碰撞告警设备从原航海雷达上采集雷达原始数据,并将数据进行变换和二次信息处理,使系统具有自动目标跟踪、危险目标自动识别以及各种危险目标告警的功能。在不影响原航海雷达功能的前提下,为其增加了防撞避碰的功能。

A marine collision avoidance alarm equipment based on FPGA is designed in the paper. This equipment is general-ly used on small and medium ships. It could work together with seafaring radar on the ship and constitute a new system with sea-faring radar. The marine collision avoidance alarm equipment could collects data of seafaring radar and processes the data so that it achieves the function of targets tracking, target identification and automatic alarming in all hazard levels. As a result, we achieve the goal of adding function of collision avoidance to the seafaring radar and not affecting its primary function.
