摘要
介绍了气压高度表的原理误差补偿方法,给出了基于ARM-Linux和ARM9处理器的气压高度表数据采集、处理软件的设计过程,开发出了一套手持式气压高度差计.采用曲面拟合方法进行气压高度表的原理误差补偿,提高了压力传感器的实际输出精度.
This paper introduces the principle error compensation method of barometer,the design of embedded error compensation and data acquisition for HPB on ARM-Linux and ARM9 processor is given.A hand-held meter of pressure altitude difference is developed.The surface fitting method is used for pressure altimeter error compensation to improve the actual output accuracy.The result has practical value on HPB accuracy and integrated navigation.
