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。
A design of temperature monitoring alarm system is presented using DSI2U to detect temperature, and transform the temperature signal into a digital Serial output Signal automatically. Microcontrolter 80C5i is adopted as the main control systeru to receive the converted digital signals The upper and lower limits of the temperature meas- urement 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.
