摘　　要：通过搭建一套远程控制系统来启动调频发射机备机,使值班员只需点击一个按钮就能在数秒内实现修改激励器频率、上机信号及发射机加电开机操作,快速完成备播操作。程序使用结果显示:大大缩短了值班人员在使用备机维持播出时所需要消耗的操作时间,为挽回播出事故作出了一定的贡献。此系统为维持安全播出提供了一种低成本并高效的思路,提高了工作效率。By setting up a remote control system to start stand-by FM transmitter, operator on duty can modify exciter frequency and operate signal and power on transmitter within a few seconds by clicking a button, and quickly maintain broadcasting. The results show that operation time consumed by operator on duty when using standby machine to maintain broadcasting is greatly shortened, which makes a certain contribution to the recovery of broadcasting accident. This system provides a low-cost and high-efficiency way for maintaining safe broadcasting, and improves work efficiency.
