摘要
船舶自动识别系统——AIS采用SOTDMA通信协议,利用VHF进行海上通信,在船舶航行安全中起到非常重要的作用。而AIS通信过程中的信道占用情况在真实AIS设备上不能被直观显示出来。本课题基于真实AIS设备的数据源,设计将AIS信道A和信道B的时隙占用情况以状态图的方式实时显示。通过本实验平台,学生可以更加直观地观察到AIS时隙预约与占用情况。
The Automatic Identifi cation System（AIS） is playing an important role in the vessel navigation safety with the communication protocol of SOTDMA by marine VHF. While the occupancy process of the channel during AIS communication cannot be displayed visually in the real AIS equipment. Based on the data source of AIS equipment, this project design a state diagram of the slots which can display the occupancy of the channel A and channel B in real-time. Through the experimental platform, the students can observe the reservation and occupancy of the channel slots more intuitive.
