摘要
本文针对目前调频N+1播出系统中运维工作量大、倒换操作复杂、值机困难等实际难点和缺点,分析了调频发射机N+1倒换中的关键技术难点,总结了智能倒换系统中的自动倒换判决条件、自动倒换流程、倒换设计原则,针对性地提出包含音频切换器、同轴控制器和综合监控软件系统为一体的综合设计方案。
The existing FM N＋1 broadcasting system has many practical difficulties such as large workload, complicated switching operation and daily maintenance work. This paper firstly analyzes the key technical factors, and summarizes the auto-switching judged condition, auto-switching procedure and switching principle. Finally, it proposes a comprehensive scheme including audio switcher, coaxial controller and monitoring software together.
