The Research Of The Automatic Identification System And The Key Technologies

Along with the global shipping industry vigorous development, the navigation technology enhancement also more and more is valued. Last century, the ships correspondence mainly utilizes the VHF correspondent technology, the radar and so on has distinguishes the ships the function, but because modern shipping safe request enhancement, radar appears its limitation. Along with the digital communication technology, the computer technology as well as the network information technology rapid development, the AIS technical foundation is day by day mature, to helps the navigation in the shipping supposes under each request more and more high situation, the ships automatic identification system arises at the historic moment. AIS is starts in last century 90's from North America and Western Europe's some countries to emerge and to develop, these countries also is continuously walks in the AIS application in the front row, the technology standard unceasingly renews. The Chinese shipping to the AIS time-sharing attention, the research work unceasingly is also thorough, and developed many times tests.First, in his paper studied this topic to the AIS development present situation carries on the introduction to the sea communication safety control significance, and explained the goal of study AIS, to the AIS system constitution, the main function and the principle of work carrying on a more detailed elaboration. The 3rd chapter conducted more thorough research to the AIS system essential technology (SOTDMA) and its the work flow from the organization. This article research to the system work with the simulation experiment method, the experiment achieves the anticipated goal, basically obtained successfully, indicated the SOTDMA technology might in the AIS system the correct utilization, realized its digital mobile communication system function. This article also analysis enormously...
