基于STM32的调频广播监测报警器设计

Design of Frequency Modulation Broadcasting Monitoring Alarm Based on STM32

为提高发射台站的监测能力,介绍调频广播监测与报警器的硬件设计方案。该报警器具有性能稳定、音质逼真、长时间工作无频偏、显示直观及噪声小等优点,能够实时监测4路调频广播信号,也能选择一路监听,当无载波或无音频信号时,蜂鸣器会发出报警信息。

To improve the monitoring capability of the transmission station,this paper introduces the hardware design scheme of frequency modulation broadcasting monitoring and alarm.This alarm has the advantages of stable performance,realistic sound quality,long-term operation without frequency deviation,intuitive display,and low noise.It can monitor four frequency modulation broadcast signals in real time,and can also choose one monitoring channel.When there is no carrier or audio signal,the buzzer will emit an alarm message.
