摘要:

设计了一款用于温度监控报警系统,采用DS18B20温度检测,可自动将采集的温度信号转化为数字信号串行输出。采用单片机80C51作为主控制系统,可接受采集转化后的数字信号。通过按键可设定温度测量范围的上、下限,并可开机自动复位。数显采用4位LED动态扫描显示相应的温度值。语音播报采用ISD1420,将数显温度值用语音的方式播报。

Abstract:

A design of temperature monitoring alarm system is presented using DS18B20 to detect temperature,and transform the temperature signal into a digital serial output signal automatically.Microcontroller 80C51 is adopted as the main control system to receive the converted digital signals The upper and lower limits of the temperature measurement range can be set by pushing buttons,and automatically reset with booting.The 4-digit LED dynamic scanning is used to display temperature values,and ISD1420 is adopted for voice broadcast of the temperature values.

Key words: microcontroller;DS18B20;ISD1420;80C51
