摘要
为了实现远程实时监测工业污水的排放,研究设计出一种通过电话网络传输DTMF信号进行远程控制的智能监测系统。该系统是以单片机AT89C51和DTMF解码电路MT8870为核心元件。给出了主要硬件电路设计,验证了系统的可行性。
In order to achieve real-time remote monitoring in industrial wastewater discharge, an intelligent monitoring system is designed to transmit information by DTMF signal through telephone network. SCM AT89C51 and DTMF decoder MT8870 are the core components in this system. The main hardware construction and software flow are presented and the feasibility of the system is also validated in this paper.
