【摘要】：近年来,随着科学技术的进步与社会的发展,人们已经离不开网络,海面上的渔民需要网络通信来填补枯燥乏味的生活,海上作业的工作船需要网络支持作业,海警舰船、海军等国防力量也同样需要网络支持日常作业以及满足船员生活娱乐所需网络。在海洋宽带卫星双向数据通信装备技术应用方面,对其进行低成本的研究,建立海上卫星宽带网络,有利于全面促进海上丝绸之路沿线国家在多领域的交流与发展,将成为发展海上丝绸之路经济和二十一世纪海上丝绸之路建设的重要保障。研究低成本海洋宽带卫星通信装备技术应用,建立海上卫星宽带网络,有利于实践舟山“智慧舟山,智慧海洋”战略,提高海洋权益保障能力。VSAT(Very Small Aperture Terminal,甚小孔径终端)具有速率高、性能强、资费低等优点,由于其独特的优点,VSAT系统逐渐吸引了众多船员的关注。VSAT系统为船舶提供稳定的且基于卫星的因特网接入和公用电话交换网服务,成为船只与陆地之间进行通信的主要方式之一。在VSAT的使用上,卫星参数的改变以及运行状态的控制便成了关键问题。对于漂泊在海上的船只,终端一旦软件进行版本更新升级,即时的更新数据又是做不到的,进行天线的安装、维护更是受到诸多限制。船载VSAT远程监控系统便可以解决以上难题。本文以船载VSAT系统为对象,研究开发了一套船载VSAT远程监控系统,首先对船载VSAT远程监控系统进行了必要的需求分析,研究并进行了系统的整体及软件、硬件设计,移植FreeRTOS操作系统及LwIP协议栈,实现了终端及服务器端功能,并且对系统进行了测试运行,最后根据其运行结果总结出不足。船载VSAT远程监控系统针对某公司委托研发,为实用型项目,该项目具有巨大实用价值及现实意义。
[Abstract]:In recent years, with the progress of science and technology and the development of society, people have been inseparable from the network. Fishermen on the sea need network communication to fill the boring life. Defense forces such as the Navy also need networks to support daily operations and meet the needs of crew life and entertainment. In the application of marine broadband satellite two-way data communication equipment, the low-cost research and the establishment of offshore satellite broadband network will be conducive to the overall promotion of exchanges and development in various fields among the countries along the maritime Silk Road. It will become an important guarantee for the development of the maritime Silk Road economy and the construction of the Maritime Silk Road in the 21 ~ (th) century. The research on the application of low-cost marine broadband satellite communication equipment and the establishment of offshore satellite broadband network are beneficial to the implementation of Zhoushan's strategy of "wisdom Zhoushan, intelligent ocean". To improve the capability of marine rights and interests protection .VSATO very small Aperture terminal (VSAT) has the advantages of high speed, strong performance, low tariff, etc. Because of its unique advantages, VSAT system has gradually attracted the attention of many crew members. VSAT system provides stable and satellite-based Internet access and public telephone switching network services for ships, and has become one of the main ways to communicate between ships and land. In the use of VSAT, the change of satellite parameters and the control of the operating state become the key problems. For ships drifting on the sea, once the software is updated and upgraded, it is impossible to update the data immediately, and the installation and maintenance of antennas are restricted. The VSAT remote monitoring system can solve the above problems. In this paper, a shipborne VSAT remote monitoring system is studied and developed. Firstly, the necessary requirements of the shipborne VSAT remote monitoring system are analyzed, and the whole system, software and hardware design are studied and carried out. The FreeRTOS operating system and LwIP protocol stack are transplanted to realize the functions of terminal and server, and the system is tested and run. The shipborne VSAT remote monitoring system is a practical project, which is commissioned by a company. It has great practical value and practical significance.
