基于单片机的霍尔效应实验数据采集和显示系统的研发

摘要

The paper introduces a system of data acquisition,transmission and display. The system is based on MCU,the process of data acquisition is based on the Hall effect which is used for measuring the magnetic field in physics experiment of university. The structure,function hardware components,software design and imple-menting details are described in detail. The MCU communicates with PC machine through USB1. 1 communica-tion protocol,which is adopted in the system. Through the A/D conversion module,STC89C52RC MCU mod-ule,serial port communication, data processing and display module to realize an efficient data acquisition, transmission and display. This system has a certain application foreground and commercial value in experiment teaching.%介绍了一种基于单片机的数据采集、传输和显示系统，该系统是以大学物理实验中的霍尔效应测磁场实验为基础，阐述了其结构、功能、硬件及软件的设计过程。本系统采用单片机通过R232协议和PC机进行通信，通过A/D转换模块、STC89C52RC单片机主控模块、串口通信、数据处理和显示等模块来实现一种高效的数据采集、传输和显示，该系统在实验教学中具有一定的应用前景和商业价值。
