基于ARM嵌入式系统的船舶导航定位系统设计

Ship navigation and positioning system based on ARM embedded system design

船舶导航定位系统对于船舶实现安全航行具有非常重要的作用。当前船舶导航系统在稳定性以及功耗上仍然存在一些问题,本文提出一种基于ARM嵌入式系统的船舶导航定位系统,ARM具有功耗低、处理速度快、具备多种数据接口、实时性好等优点。本文研究了船舶导航定位系统的整体结构,系统可以实现船舶定位、船舶避碰、历史记录等功能,详细设计了串口电平转换电路以及FLASH电路,对NMEA-1083协议进行了简要分析,最后设计了软件的系统界面。

Ship navigation and positioning system for ship safe navigation has a very important role. The ship navigation system there are still some problems on stability and power consumption, this paper proposes a ship navigation and positioning system based on ARM embedded system, ARM have low power consumption, fast processing speed, with a variety of data interface, the advantages of good real-time performance. This paper studies the overall structure of ship navigation and positioning system, the system can realize positioning, ship collision, history, and other functions, the detailed design of a serial port level conversion circuit and FLASH circuit, protocol of NMEA-1083 is briefly analyzed, the design of the software system interface.
