基于手机的分布式街道噪音检测系统

A Distributing Street Noise Monitored System Based on Mobile Telephone

介绍了一种以 80 31单片机为核心的分布式街道噪音检测系统。由于它利用手机通过公共无线蜂窝网络进行数据通信 ,因此通信距离可以不受限制 ,同时也实现了可移动检测 ;另外 ,数据以双音频方式传输 ,使之有很强的抗干扰能力。

This paper describes a distributing street noise monitored system. It is controlled by 8031 singlechip. The noise data can be transmitted in public wireless network by mobile telephone. So the transmission distance is unlimited. And there is strong antiinterference ability in this system as the data is modulated with double audio frequency model.
