摘要
本文介绍基于AT89C51单片机、C语言和DS18B20传感器的多点温度测量系统设计及其在Proteus平台下的仿真,并对系统实际运行的结果数据进行分析。本设计并未采用DS18B20惯用的一线制总线结构,而是利用51单片机的并行口,同步快速读取8支DS18B20的温度,实现了在多点温度测量系统中对多个传感器的快速精确识别和处理,并给出了具体的实现方法、仿真效果和实验数据。
Multipoint temperature measurement system based on DS18B20 and AT89C51 microcontroller is designed and simulated by Proteus. This paper introduces the software and hardware design of this system and gives the analysis of the experimental data got from the actual operating system. The system has such advantages as novel circuit design, quick measurement speed, high measurement accuracy, and good practicality. This paper gives implementation of specific simulation results and experimental data.
