船舶Radio Telex设备仿真的关键技术研究

The Key Technology Research on Shipping Radio Telex Equipment Simulation

Radio Telex无线电传设备,是GMDSS地面通信系统的一种主要终端。文中介绍了以VisualC++6.0为工具开发GMDSS船舶Radio Telex仿真系统的两项关键技术:在Windows环境下利用MFC基于对话框的应用程序仿真设备在DOS环境下的键盘输入;运用局域网UDP协议仿真设备的电传通信过程。

The Radio Telex wireless transmission equipment is major terminal of GMDSS terrestrial communication system.This paper puts forward two key technologies for GMDSS ship Radio Telex simulator system based on VC ＋＋ 6.0 .One key technology is using MFC application program based on dialog box under Windows environment to simulate keyboard input in DOS. The other is using local area network UDP protocol to simulate the telex communication process of equipment.
