基于Arduino和PLX-DAQ的多路温度采集系统设计

Design of multi-channel temperature acquisition system based on Arduino and PLX-DAQ

针对部分地区学校的数字化实验存在缺欠问题,本文采用Arduino Nano系列为核心控制器,结合DS18B20温度传感器单总线信号传输特点,利用Parallax公司的PLX-DAQ软件进行设计一款多路温度采集系统。通过串口实现Arduino与Excel的通信,在Excel采集界面能够自动地实时采集数据和绘制曲线,可直接对数据进行分析、处理及保存。该系统可以实现传统实验与数字化实验技术的相互融合,丰富中学物理实验教学方式多样化,促进中学物理实验教学质量的提高。

In view of the shortcomings of digital experiments in schools in some areas, this paper uses Arduino Nano series as the core controller, combines the single-bus signal transmission characteristics of DS18B20 temperature sensor, and uses Parallax’s PLX-DAQ software to design a multi-channel temperature acquisition system. Through the serial port to realize the communication between Arduino and Excel, the Excel acquisition interface can automatically collect data and draw curves in real time, and the data can be directly analyzed, processed and saved. The system can realize the integration of traditional experiment and digital experimental technology, enrich the diversification of middle school physics experiment teaching methods, and promote the improvement of the teaching quality of middle school physics experiment.
