摘要
本文介绍一种由８０３１单片机为核心配上ＤＴＭＦ解码器、编译码器所构成的少线制总线结构呼叫对讲系统，并给出硬件设计和软件编程框图。
he paper introduces a kind of interinterphone system with bus construction beat needs only a few ohs. The unit is composed principally of 8031 microprocessor being matched well with DTMF decoder, coder and translator. This paper also gives out the design of hardware and correspondent block diagram of program.
