摘　　要：介绍了磁场分布测量系统的硬件结构和软件设计方案。该系统将单片机为核心的小系统,结合霍尔传感器作为前端的数据采集系统,将采集到的数据利用串口传送到PC主系统。在LabVIEW环境下对数据进行分析、处理、显示并保存。经测试,系统能方便灵活地测量磁场,3个方向的测量范围均可达到-900^+900 Gauss,测量精度达1%,并且磁场的测量结果能通过三维图形显示。A hardware structure and software module design idea of magnetic field distribution measurement system is introduced. The system uses single chip micro-controller combining hall sensors as predictive data acquisition system , sends acquired data to PC via serial port, and the PC analyzes, processes, displays and saves these data in LabVIEW environment. The system has been demonstrated to be convenient and flexible in measuring the magnetic field. The measurement range in each of three directions can reach-900 Gauss to ＋900 Gauss with a precision of 1%, and the result can be shown with 3D graphics.
