摘　　要：文中采用3个线性霍尔元件THS119、加速度传感器芯片ADXL345和单片机测量系统实现了空间静态三维磁感应强度的测量。4个芯片紧凑地贴在探头相互正交的4个平面上,依据重力加速度坐标对磁感应强度坐标进行修正。数据采集电路为探头提供工作电流,完成数据采集并实现与计算机的通信。计算机显示程序使用Lab VIEW图形化编程语言编写,用于显示磁感应强度的大小、三维分量、方向角和三维空间取向图。The measurement of spatial static three dimensional magnetic induction intensity using three linear hall-effect ele-ments THS119,the accelerator sensor chip ADXL345 and the single chip microcomputer measuring system was realized.Four chips stuck tightly on probe of the four orthogonal plane,and coordinates of magnetic induction intensity were corrected according to the co-ordinates of acceleration of gravity.The data acquisition circuit provided the probe operating current,and completed the data collection and realized the communication with computers.The computer display program which was used to display the magnitude,the three di-mensional component,the direction angle and the three-dimensional orientation figure of the magnetic induction intensity was pro-grammed by LabVIEW which was a graphical programming language.
