摘要
提出了基于等间距磁刻度应变电磁检测的新方法。设计了信号处理和波形转换电路,将对应变的检测转化成为对时间量的计测,推导了时间量与构件应变之间的数学表达式。以AT89C52单片机为核心,开发了应变检测系统的数据采集系统。利用上位机虚拟仪器完成对检测结果的显示、存储和打印等功能。
The method based on equispaced magnetic scale of linear strain detection is introduced.The electrocircuit of signal processing and conversion of obtained wave is designed and the detection of strain of mechanical component is converting to the calculation of total time of the obtained wave.And the calculation formula between the measured time and the stain of component is given.The data acquisition is studied based on AT89C52 microcontroller.The function of display,save and print is accomplished by virtual instuments.
