摘　　要：基于MLX90393芯片设计了一种新型的空间角位移传感器,详细阐述了该传感器的工作原理、设计方法和数学模型。该传感器基于霍尔效应可以测量空间X、Y和Z三个方向的磁场分量,通过数学建模将这三个值转化成空间角位移分量α和β,从而确定一个物体在空间中的角位移。本实验基于一个空间角位移平台和STM32硬件开发平台,捕获以及输出MLX90393测量数据,经过计算机处理、统计分析以及数学建模,最终得出物体在空间移动时的角位移数据。A novel spatial angular displacement sensor based on MLX90393 is designed in this paper,its working principle,design method and mathematical model are elaborated in detail.The sensor can measure the magnetic field components in the three directions of space X,Y,Z,and convert these three values into spatial angular displacement componentsαandβby a reasonable mathematical model to determine the angular displacement of an object in space.This experiment is based on a spatial angular displacement platform and STM32 hardware development platform.The STM32 embedded system captures and outputs the measurement data of MLX90393.After computer processing,statistical analysis and mathematical modeling,the angular displacement data of the object is finally obtained when it moves in space.
