Design Research And Practice Of Digital Audio Signal Monitoring Equipment

Radio and television monitoring is an important part of the radio and television broadcasting is animportant guarantee for broadcast on radio and television safety is an important means to ensure thatthe broadcast efficiency and coverage effects, an important part of self-monitoring of radio andtelevision. To make the complex signal can be monitored under a unified framework, using the IP of avariety of signal processing, in order to achieve centralized monitoring of multiple types of signals tofacilitate equipment maintenance, centralized management and system expansion.To ensure the safety broadcast for the radio station play center is the first and fundamental task.Often broadcast from the total control monitoring system reflected in the broadcast front-line staff isalso found through the monitoring system to broadcast and judgment point of failure, and thus foremergency treatment, therefore, the monitoring equipment to ensure safety broadcast a pivotal position.With the development of radio and television broadcasting and the triple play of substantive advancethe trend of radio and television broadcast and monitoring has emerged as the development of digital,networked, intelligent direction, the traditional architecture of the monitoring equipment showed thegreat updates. Solve this problem, the use of embedded technology to build a radio and televisionmonitoring equipment, and its hardware, software implementation and the use of equipment to buildthe monitoring system to be discussed.Digital audio signal monitoring equipment as an important part of quality monitoring of the radioshow, has become indispensable,"System Tools". In the digital age, in order to better achieve thequality monitoring of radio and television programs, digital audio signal monitoring device is a boldattempt on new technologies, new tools and methods.The digital audio signal monitoring equipment in order to achieve automation, digitization andnetworking of the radio broadcast signal monitoring. In this paper, the design of the digital audio signalmonitoring device can simultaneously monitor eight analog audio channels, and monitoring equipmentwhen any one channel audio analog signal interrupted a few seconds or more when the alarmautomatically (automatic alarm interrupt can be set according to the needs) prompt on duty timelydetection of failure, check, make a deal. Digital circuits to complete the monitoring of analog audiosignal, audio signal storage and send signal to determine the interrupt signal timing and display. As aresult of digitization was designed, they are able to facilitate communication, and the host computer tofacilitate subsequent development and utilization has become an important part of the entire detectionsystem.
