基于FPGA的音频监控系统的设计与实现

Designing and implementing audio monitoring system with FPGA platform

摘要:

广播电台信号的监控是播出安全的重要保障。为了实现对电台音频信号的远程和本地监控，提出了利用FPGA来处理数字音频信号，并将处理的结果网络化传输的系统方案。文中具体阐述了系统中的音频采集、音频分析、音频切换、网络传输模块和软件的设计，并给出了系统实物图和实际测试结果。测试表明，该系统工作可靠，性能稳定，减轻了电台听音人员的负担。

Abstract:

Radio broadcast signal monitoring is an important guarantee for the safety of broadcasting. A systematic solution to process digital signal based on FPGA platform is presented，aiming for the audio remote and local monitoring. Specially addressed in the paper includes audio signal acquisition，analysis， switching，network transmission modules and software designs. Also，the picture of actual object and test results are given. Test shows that the system is reliable and of stable performance，greatly reducing the burden of the radio listener in the broadcast station.
