The Research Of Automatic Identification System (AIS) Application

The automation identification system (AIS) is one kind of new model navigation equipment of 1990's, which is many high and new technologies such as modern communication and computer applies into navigation field successfully. AIS can make ship know dynamic and static state information of vicinity ship in time, also can help administrative department to grasp ship information of it's own administering condition water area. The application of AIS not only being able to improve safety, but also can improve the validity of management, having avoided the various accident of sea , is essential equipment of digitization navigation.The thesis takes the AIS international standard as basis, studies the acquisition and code method of AIS data, studies the structure and realization method of AIS message. The thesis also analyses and studies serial interface and sentence, complete AIS coding and output and input sentence.The thesis brought forward AIS application according to the reality condition and need of navigation, such as collision preventation, aid to navigation, search and rescue, pilotage, VTS and so on. In the thesis, these functions have been complete, which not only establish theory basis but also provide experiment data for AIS application.Specifically for the need of AIS study, the thesis brought forward the concept of AIS data source system; provide systematic design plan; implement AIS data source system with Visual C++ 6.0. The system can provide dynamic and static data that belong to different ships, also be able to output sentence according to the need of scholars. The system also has realized some message that have not realized in AIS equipment, such as binary message or hydrology meteorological message. The interface of system is amicable and the manipulation is effective. It is an effective tool for AIS message and data study. The accomplishment of this system provides the preliminary emulation basis for the application of AIS, also has active meaning for the theory study of AIS.
