摘要
采用DS18B20和AT89C2051单片机研制的一种温度巡回检测系统。采用51单片机及汇编语言,完成对DS18B20的调用、中断管理、测量温度值的计算及温度值的显示等功能。通过程序实现定时对各路温度值的巡检和显示,并且在一个通道上允许用中断程序修正,以实现根据温度标称值修正传感器的目的,系统具有实用性强、可靠性高等特点。
This design is about a touring temperature measurement system based on DS18B20 and AT89C2051. It possesses the function of transfer, interuption control of DS18B20, calculation of measurement temperature and display the value of temperature based on AT89C2051 single-chip microcomputer and assembler programming language. Display program take the act of touring t and display the value of temperature in every point , and allows correct of the error through interruption program in a channel to realize the correction of the sensor according to the calibration of the temperature. This system has powerful practicability and high reliability.
