船舶通信系统是船舶的重要组成部分,具有现场通信、定位、无线电预警、导航等多种功能。船舶通信系统主要可以分为地面通信、卫星通信、定位系统和海上安全信息收发等几种,通信设备包括电台、VHF无线设备、雷达和信号基站等多种。随着计算机技术和自动化技术的迅速发展,船舶通信信号设备的自动化水平逐渐提高,同时,其故障率也随之提高。为了保障船舶通信系统的正常运行,通信信号设备的故障诊断和检测技术显得尤为重要。本文的研究对象为船舶通信系统的信号设备,利用虚拟仪器技术Labview设计和开发了一种船舶通信信号设备的故障检测系统,并对该故障诊断系统的硬件结构和软件程序进行详细介绍。本文对改善船舶通信系统的抗干扰能力,提高故障诊断速度有重要的作用。 相似文献

随着我国的近海渔业资源变得越来越贫乏,更多的渔船需要到更加偏远的海域中捕鱼,因此船舶的导航能力和航行能力要求也越来越高,通过物联网技术和北斗导航技术,人们能够实现船舶的精确定位和航行控制。本文结合最新的物联网技术,对远洋渔船进行集中管理和状态监测,能够在岸基人员的帮助下,对船舶进行远程通信和故障预警,为船舶的安全航行保驾护航,通过利用物联网技术,船舶的运行成本得到较大降低。 相似文献

计算机控制技术的发展给船舶行业带来了新的发展,为了最大限度保障船舶的航行安全,通过计算机通信技术和智能算法,人们已经能够实现船舶的自动避碰,这极大地降低了船舶的事故率。但是传统的避碰决策系统并不能同时处理大量的船舶航行数据,因此必须借助Multi-agent技术,提高船舶的避碰数据处理速度,在显著提高避碰效果的同时,有效降低了航运成本。本文通过建立基于Multi-agent技术的船舶避碰模型,分析了该技术的应用效果。 相似文献

船舶自动化水平的提高可以有效提高船舶航行的安全性,并且降低船舶工作人员的工作强度。现代船舶的很多电子自动化设备能够获取船舶的相关状态信息,如位置、航速、船内温度等,但是系统相互独立,无法实现信息共享,给船舶航行带来了很多不便。本文提出一种基于ARM嵌入式系统的船舶综合信息系统,使用以太网实现嵌入式系统和各个子系统之间的通信和数据共享,并使用触摸屏对各类信息进行显示。本文对系统硬件进行了相关设计,并对以太网通信进行了详细介绍。 相似文献
