【摘要】：近年來,隨著科學技術的進步與社會的發(fā)展,人們已經離不開網絡,海面上的漁民需要網絡通信來填補枯燥乏味的生活,海上作業(yè)的工作船需要網絡支持作業(yè),海警艦船、海軍等國防力量也同樣需要網絡支持日常作業(yè)以及滿足船員生活娛樂所需網絡。在海洋寬帶衛(wèi)星雙向數(shù)據(jù)通信裝備技術應用方面,對其進行低成本的研究,建立海上衛(wèi)星寬帶網絡,有利于全面促進海上絲綢之路沿線國家在多領域的交流與發(fā)展,將成為發(fā)展海上絲綢之路經濟和二十一世紀海上絲綢之路建設的重要保障。研究低成本海洋寬帶衛(wèi)星通信裝備技術應用,建立海上衛(wèi)星寬帶網絡,有利于實踐舟山“智慧舟山,智慧海洋”戰(zhàn)略,提高海洋權益保障能力。VSAT(Very Small Aperture Terminal,甚小孔徑終端)具有速率高、性能強、資費低等優(yōu)點,由于其獨特的優(yōu)點,VSAT系統(tǒng)逐漸吸引了眾多船員的關注。VSAT系統(tǒng)為船舶提供穩(wěn)定的且基于衛(wèi)星的因特網接入和公用電話交換網服務,成為船只與陸地之間進行通信的主要方式之一。在VSAT的使用上,衛(wèi)星參數(shù)的改變以及運行狀態(tài)的控制便成了關鍵問題。對于漂泊在海上的船只,終端一旦軟件進行版本更新升級,即時的更新數(shù)據(jù)又是做不到的,進行天線的安裝、維護更是受到諸多限制。船載VSAT遠程監(jiān)控系統(tǒng)便可以解決以上難題。本文以船載VSAT系統(tǒng)為對象,研究開發(fā)了一套船載VSAT遠程監(jiān)控系統(tǒng),首先對船載VSAT遠程監(jiān)控系統(tǒng)進行了必要的需求分析,研究并進行了系統(tǒng)的整體及軟件、硬件設計,移植FreeRTOS操作系統(tǒng)及LwIP協(xié)議棧,實現(xiàn)了終端及服務器端功能,并且對系統(tǒng)進行了測試運行,最后根據(jù)其運行結果總結出不足。船載VSAT遠程監(jiān)控系統(tǒng)針對某公司委托研發(fā),為實用型項目,該項目具有巨大實用價值及現(xiàn)實意義。
[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.
