基于USB接口的磁场分布测量系统研究

Study on Magnetic Field Measurement System Based on USB

分别介绍了基于USB接口的磁场分布测量系统中霍尔传感器模拟前端、A/D转换、USB数据采集控制通信的硬件设计以及计算机磁场分布软件设计.实际测量结果表明,与传统的指针、数字式磁场测量系统相比,该系统不仅能满足科学研究和工业对磁场分布测量的精度要求,而且具有即插即用,易于二次开发等优点.

A magnetic field measurement system based on USB is introduced. The hardware design of analog front of Hall sensor A/D conversion, USB main controller and the software design of the computer magnetic field measurement are presented. It is proved by the actual testing result, compared to the previous traditional measurement system based on needle and digital, this new system not only can meet the accuracy requirement of magnetic field measurement in the research and industry, but also is easy to redevelop.
