摘　　要：在民航领域,地空通信是确保飞行安全的关键。高质量的信号能够确保飞行员与地面管制员之间的高效沟通,从而准确传递指令和信息。如果信号质量受损,可能导致通信中断或误解,对飞行安全产生严重威胁。因此,维护和优化信号质量是保障民航安全运营的核心任务之一。以SCV-200系列信号比选器为例,对该设备的功能结构和工作原理进行分析,针对信号比选器的故障排查和可采取的预防办法进行探索,为民航领域地空通信中信号比选故障排查提供参考。In the field of civil aviation, ground-to-air communications are the key to ensuring flight safety. High-quality signals ensure efficient communication between pilots and ground controllers, thereby accurately transmitting instructions and information. If signal quality is compromised, it may lead to communication interruptions or misunderstandings, posing a serious threat to flight safety. Therefore, maintaining and optimizing signal quality is one of the core tasks to ensure safe civil aviation operations. This article takes the SCV-200 series signal comparator as an example to analyze the functional structure and working principle of the device, and explores the troubleshooting of the signal comparator and the preventive measures that can be taken to provide signals for ground-to-air communications in the civil aviation field, to provide certain reference for troubleshooting.
