摘　　要：基于STM32的北斗定时定位实验系统以STM32F103VET6微控制器芯片作为主控MCU,接收并处理北斗定位模块UM220-III的数据,实现二维定位。并根据海拔高度与大气压强间的数学关系将气压传感器采集的气压数据换算成海拔高度,经纬度二维定位与海拔高度结合,实现三维定位并通过液晶显示屏授时显示。通过该实验平台,可以丰富嵌入式实验教学内容,提高学生对嵌入式技术与我国自主建设运行的北斗卫星导航系统的了解,激发学生的学习兴趣与热情。The Beidou timing and positioning experiment system based on STM32 takes STM32F103VET6 microcontroller as the core, receives and processes the data of the Beidou positioning module UM220-III, and realizes two-dimensional positioning. According to the mathematical relationship between altitude and atmospheric pressure, the atmospheric pressure data collected by the barometric pressure sensor is converted into altitude. The two-dimensional positioning of longitude and latitude is combined with altitude to realize three-dimensional positioning and display by LCD. Through this platform, we can enrich the content of embedded experiment teaching, improve students’ understanding of embedded technology and Beidou satellite navigation system which is built and operated independently in China, and stimulate students’ interest and enthusiasm in learning.
