摘要
提出了一种利用虚拟仪器技术进行传感器动态特性标定的新方法。在介绍了传感器动态特性标定的原理和标定系统平台的结构的基础上,利用LabVIEW的图形化编程特点及其强大的开发功能,实现了激励信号的发生与标定数据的采集、存储和处理,同时利用MATLAB对动态性能指标固有频率和阻尼比进行最优计算。设计系统具有通用性好、操作方便、精度高等优点。
A new method to calibrate the dynamic characteristics of sensor was presented.Based on the introductions of the principle of the dynamic characteristics calibration of sensor and the structure of the calibration system,the LabVIEW,for its graphical programming and strong development tools,was utilized to produce the active signals and to realize the collection,storage and processing of the calibrating data.The natural frequency and the damping ratio,which are the criterion to describe the dynamic characteristics the sensor,are worked out by MATLAB.Results show that the system has good commonality,easy to operate,high precision.
