【摘要】 根据海上中/高频通信原理和通信程序,研制海上中/高频通信控件(ActiveX控件),仿真海上中/高频收发信机功能;使用UDP协议(user datagram protocol)广播电文;使用VB语言编制SAILOR中/高频组合电台控制单元模拟器、窄带直接印子电报(NBDP)终端模拟器、模拟海岸电台和模拟陆地电传用户,并采用后台支持、仿真数据库等网络仿真海上中/高频各类通信。该仿真系统可不设服务器,更能反映海上中/高频通信特性,并可方便组网训练。更多还原

【Abstract】 According to maritime medium/high frequency communication principium and program,the developed maritime medium/high frequency communication ActiveX control can simulate maritime medium/high frequency transceiver function.The user datagram protocol(UDP) was used to broadcast message,the SAILOR medium/high frequency console unit simulator,NBDP simulator,coast station simulator and land telex consumer simulator were progamed by VB language.The background sustain and simulating database were adopted to simulate all kinds of maritime medium/high frequency communication in computer network.The system has no server,so it has the characteristics of maritime medium/high frequency traffic and conveniences to setup network for training and has better practicability.更多还原
