内河船舶操纵模拟器中AIS的仿真

Simulation of AIS in Inland Waterway Ship Handling Simulator

在内河航运中,船舶自动识别系统(AIS)能实时提供本船及他船的航行信息,为船舶安全航行提供有力的保障。当前内河船舶操纵模拟器已广泛应用于船员培训中,其中AIS仿真设备的地位尤为突出。基于此,对内河船舶使用的B类AIS的功能需求进行分析,采用VC-MFC软件搭建AIS仿真软件平台,采用动态链接库设计AIS仿真软件的架构,采用半透明方法实现亮度和对比度调整、内存共享、多输入法切换及船舶间的距离计算等关键技术,完成内河船舶操纵模拟器中AIS的仿真。

Automatic Identification System(AIS)offers real-time navigation information of a ship and its surrounding ships in inland waterway transportation so it provides strong support for safe navigation.As inland waterway ship handling simulator is commonly used in crew training nowadays AIS simulation equipment becomes even more important.This paper analyzes the functional requirements of Type B AIS for inland waterway applications,in which VC-MFC software is used to establish the AIS simulation software platform,Dynamic Link Library(DLL)is used to design the AIS simulation software framework and some key technologies such as memory share,multiple input switch,distance calculation between two ships and brightness and contrast adjustment achieved by translucent method are used to realize the AIS simulation in the inland waterway ship handling simulator.
