摘要
本文针对调频发射机房存在多工器系统和发射天线无备份的问题,提出了一种新的构建调频备份发射系统的思路。该系统实现了发射机、多工器以及发射天线的全备份,具有体积小巧、结构紧凑、易实现和易操作等优点,有效提升了发射系统的安全性和可靠性。
This paper provides a new way to construct an FM backup transmission system to address the issues of multiplexer systems and the lack of backup transmission antennas in the frequency modulation transmission room.This system achieves full backup of transmitters,multiplexers,and transmitting antennas,with advantages such as compact size,compact structure,easy implementation,and easy operation,effectively improving the safety and reliability of the transmission system.
