摘　　要：本文介绍了一种基于嵌入式ARM处理器和嵌入式操作系统Linux的FM广播的监测接收机软硬件设计方法。利用FM数字解调芯片对监测点的FM信号进行接收,并把FM的信号的监测参数和解调后的音频信号通过网络回传到监测中心,以实现对FM覆盖质量的实时监控。本文提出了一种基于嵌入式ARM的开放性结构,在改变相应的信号接收解调模块后,可以实现对DTMB、CMMB等系统的实时监测。This paper introduces a software and hardware design idea of a FM radio monitoring and receiving machine based on embedded ARM processer and embedded linux operation system.The system uses a FM-demodulation chip to receive the FM radio signal in measured area and puts the monitoring parameter and demodulated analog audio signal to monitoring center via net,which gives a way of monitoring the coverage quality of FM radio.This paper puts up an idea of a unlocking structure based on ARM-LINUX,which can real-timely monitor DTMB and CMMB system after changing the receiving-demodulating module correspondingly.
