摘　　要：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。In the airborne frequency spectrum monitoring system, fiber/copper cable serves as the linking media in Ethernet data communication application, and could make the system more flexible, reliable and robust. These two medias could backup each other in the applications. An adaptive technology of between fiber connection and copper-cable connection is described particularly in this paper, including principle description, hardware and software design, and debugging method. Finally the results of experimental application are also introduced briefly.
