　　經(jīng)濟(jì)全球化和世界貿(mào)易量的增加使國(guó)際航運(yùn)業(yè)得到了快速發(fā)展。船舶數(shù)量、船舶噸位和水上交通密度也在不斷增加,導(dǎo)致發(fā)生海上事故的可能性隨之增加。這是對(duì)海洋安全和海洋環(huán)境的重大威脅。今天,隨著先進(jìn)技術(shù)的發(fā)展和應(yīng)用到航運(yùn)業(yè),相應(yīng)地船舶上裝備了越來(lái)越多的新設(shè)備。這些船用設(shè)備的性能也在得到不斷的完善和增加。AIS是一種自動(dòng)識(shí)別系統(tǒng),它由岸站和艦載設(shè)備組成,是SOLAS公約規(guī)定的履約船舶強(qiáng)制配備的導(dǎo)航系統(tǒng)。AIS工作在甚高頻段（VHF）,使用SOTDMA調(diào)制方式將船舶信息發(fā)送到其他船舶和岸站,其中的船位信息來(lái)自AIS設(shè)備內(nèi)置的GNSS芯片。AIS系統(tǒng)可以有效提高海上安全性,并能夠?yàn)楹叫�、避碰、海上救援、通信、船舶管理等提供有效的技術(shù)支持。本文深入挖掘AIS信息,研究基于AIS信息的船舶避碰與海上安全保障的理論與技術(shù)。在AIS現(xiàn)有技術(shù)的應(yīng)用基礎(chǔ)上,深入研究如何根據(jù)國(guó)際海事組織和國(guó)際電聯(lián)的建議對(duì)系統(tǒng)的各類信息充分挖掘,研究避碰與預(yù)警的理論與關(guān)鍵技術(shù),并在理論研究的基礎(chǔ)上,進(jìn)行實(shí)際系統(tǒng)的技術(shù)實(shí)現(xiàn)�？紤]到超出AIS岸站覆蓋范圍的海上作業(yè)船舶和漁船,進(jìn)行了該海域定位增強(qiáng)技術(shù)的研究,以提高定位的準(zhǔn)確性,從而確保該船...
