介绍了一种机载环境中光电自适应以太网通信技术在频谱检测中的应用,通信介质采用光纤和电缆双冗余热备份自适应的连接方式。光纤和电缆同时接入网络,通常情况下光纤作为主要的通信介质,当光纤链路发生故障时自动切换到电缆上,不影响系统的连接和中断系统的传输,提高了机载设备数据通信的灵活性和可靠性。对频谱监测的工作流程和光电自适应通信的原理进行了详细的描述,并对硬件和软件设计、调试方法及试验应用结果进行描述。
This paper introduces the application of photoelectric adaptive Ethernet communication technology in spectrum detection in airborne environment. The communication medium adopts the dual redundant hot backup adaptive connection mode of optical fiber and cable. Optical fiber and cable access to the network at the same time, usually fiber as the main communication medium, when the fiber link failure automatically switches to the cable, does not affect the system connection and interrupt system transmission, improve airborne equipment data communication Flexibility and reliability. The working process of spectrum monitoring and the principle of photoelectric self-adaptive communication are described in detail, and the hardware and software design, debugging methods and test application results are described.
