摘要
海上通信环境相比陆地系统更加复杂,通信噪声干扰严重、信道变化多端,为了提高海航模拟训练速度及质量,需要一套高可靠性的通信系统以保障船舶各单元以及各船舶之间的通信。VHF通信仿真系统为航海模拟器的重要组成部件,通过特定的频率与服务端建立连接,其信号传输时效性及误码率性能直接关系着航海模拟器性能。本文在研究了海上VHF通信仿真系统结构的基础上,设计了基于Internet的嵌入式VHF通信系统硬件及软件,最后进行了仿真。
The maritime communication environment is more complex than the terrestrial system, noise is seriously and channel communication is complex. In order to improve the quality and speed of Hainan simulation training, requires a high availability communication system to ensure the communication between each unit and different ship. VHF communication simulation system is an important component of the navigation simulator, which is connected with the server through a specific frequency. The signal transmission efficiency and bit error rate are directly related to the performance of navigation simulator. This paper studies the structure of the marine communication simulation system, designs the hardware and software of the embedded communication system, and finally carries out the simulation.
