用LabVIEW 软件、霍尔传感器、步进电机、继电器、单片机采集系统，构建了亥姆霍兹线圈磁场的自动测量系统。以PC作为上位机，LabVIEW程序控制PC与单片机通信，单片机接收到指令，控制步进电机工作，带动霍尔传感器，传感器采集信号送到单片机，再送到上位机，用LabVIEW进行数据处理和显示，从而实现了亥姆零兹线圈磁场的自动测量。

An automatic measurement system of Helmholtz coil’s magnetic field was designed , which consisted of LabVIEW software , Hall sensor , stepper motor , relay and microcontroller (MCU) acquisition system .The LabVIEW code was responsible for communication control between the MCU and the host ;when commands were received ,the MCU could controlled the stepper motor to drive Hall sensor to gather signals and send them to the host computer .The LabVIEW code was also in charge of the signal processing and data display .
