珠江口水域AIS基站的设计

Analysis of AIS base stations design for the Pearl river delta

分析珠江口AIS系统的吞吐性能及其影响因素的评价方式,计算出AIS基站在备选位置两种概率情形下的覆盖范围,同时,对AIS基站使用的两种频道的场强进行了测试,结果符合AIS基站正常工作所具备的电磁环境.基于此,依据基站的选址原则,确定基站的具体位置,并在海图上加以描绘,实现了珠江口AIS基站科学、合理的布局,构造完整的AIS网络,使珠江口水域达到无缝覆盖.最后,设计出珠江口水域AIS布局的总体方案.

This article analyzes the throughput performance and its influence factors, as well as evaluation method of AIS in the Pearl River Delta. The covering range of AIS base stations is computed under two kinds of the certain probability. At the same time, the test of field-strength of two channels used by the AIS base stations is proceeded. The result accords with the electromagnetism environment of AIS. According to the above-mentioned analysis and the choosing address principle, the article makes certain the concrete position of AIS base stations, and takes it into the description on the maritime map. The seientific, reasonable layout of AIS base stations is carried out. Information transmission is seamlessly realized through the integrated AIS network. Finally, the overall scheme is designed for the Pearl River Delta.
