由于信号源不稳定,值班人员工作责任性不强等原因,中波发射台常出现调幅度异态播出事故,为了避免出现此类事故,设计出了中波发射机调幅度异态声光报警系统。该系统具有电路简单易调,工作稳定可靠,安装容易等特点。在避免调幅度异态事故方面起到了很好的作用。
Due to the unstable signal source and the low duty of duty personnel on duty, the amplitude of the amplitude modulation aberration broadcast often appears on the launch pad of China wave transmitters. In order to avoid such accidents, the amplitude-modulated acousto-optic aberration of the mid-wave transmitter is designed alarm system. The system has a simple and easy circuit adjustment, stable and reliable, easy to install and so on. In order to avoid amplitude modulation abnormalities played a very good role.
