The broadcast quality is affected when the multi-channel programs and multiple frequency modulation programs is monitored manually. To solve the problem, a domination system of multi-channel programs is successfully designed. With this system, alarming can be given out automatically in case of the failure such as losing at high voltage, no power output, signal sources interruption, with carrier frequency but no modulation, lack of track etc. Real-time monitor and control of multi-channel and...

The broadcast quality is affected when the multi-channel programs and multiple frequency modulation programs is monitored manually. To solve the problem, a domination system of multi-channel programs is successfully designed. With this system, alarming can be given out automatically in case of the failure such as losing at high voltage, no power output, signal sources interruption, with carrier frequency but no modulation, lack of track etc. Real-time monitor and control of multi-channel and frequency modulation broadcasting program is realized. The system has already been successfully applied in Jinzhou TV broadcasting Station. As a result, the working pressure of person on duty is greatly lessened, and the efficiency and broadcasting quality is improved as well.

针对电视发射台人工监视多套电视节目、多套调频节目影响播出质量的问题,成功地设计和制作出多套节目监视监听系统,它能有效地对系统发生的故障,如掉高压、无功率输出、信号源中断、有载频无调制、缺声道等进行自动报警和实时监控。该系统现已成功地应用于锦州电视发射台,对多套电视和调频广播节目进行实时监控,大大降低了值班人员的工作强度,提高了工作效率和节目的播出质量。
