应变式加速度传感器灵敏度校准虚拟仪器设计

Calibration for the strain gauge accelerometers using VI

虚拟仪器是虚拟现实技术在仪器业中的一种应用,具有传统仪器无法实现的许多功能。本文主要利用美国NI公司推出的LABVIEW虚拟仪器设计平台,实现应变式加速度传感器灵敏度校准的虚拟仪器设计的方法。在数据采集和处理过程中,将传感器特性归一化,有效减少非线性误差,提高测量的准确度。

Virtual instrument is a kind of application using virtual technology in the instrument which actualizes more functions than tradition instruments.The paper introduces the software design for the calibration of the strain gauge accelerometers based on LABVIEW software platform designed by NI company of America.The non-linearity error can be decreased effectively so that the sensor accuracy is enhanced and characteristic of sensor is normalized.
