摘要
鉴于目前市场上已出现种类繁多的楼宇对讲机,介绍了一种利用AT89S52单片机新设计的对讲机分机,并详细介绍了各部分电路的设计与工作原理,最后对语音部分的线路进行了仿真测试。测试结果表明,该线路失真率低于市场上同类产品。同时通过实物测试也说明该机型结构简单小巧,操作方便,具有良好的实时性和快速性,因此具有良好的实用性。
In view of so many kinds of interphones for buildings in the market,a new design of extension in interphones based on AT89S52 is introduced and the design of each part in the whole circuit as well as its working principle is detailed in this paper. At last a simulation is taken for the audio part and the result also expresses that the distortion of this kind is lower than any other kinds in the market. Also by the whole test,this kind of extension is simply composed and operated and has well capability of real - time and speediness so that it has well practicalitv.
