摘要
现有的船舶自动识别通信系统(AIS)主要用于VTS领域船舶报文的传输,其无线通信网络采用STDMA技术,信道负载率符合通信网络性能要求。随着海上船舶电子设备及业务种类的增加,通信信道负载加重,无线通信网络的吞吐量较易出现堵塞,如何建立合理的通信仿真模型对船舶自动识别系统的网络性能进行仿真是解决问题的关键。本文在研究现有船舶自动识别系统网络架构的基础上,设计一套AIS网络性能仿真系统,并进行仿真测试。
The existing ship automatic identification communication system is mainly used for the transmission of the ship 's message in the VTS field,it 's wireless communication network used STDMA technology,the channel load rate satify the requirements of the communication network. With the increase of the electronic equipment and business types,the load of the communication channel is heavier,and the throughput of the wireless communication network is more easily to be blocked. How to establish a reasonable communication simulation model to simulate the network performance of the ship automatic identification system is the key to solve the problem. In this paper,based on the study of the existing ship automatic identification system network architecture,a set of AIS network performance simulation system is designed,and the simulation test is carried out.
