针对目前光电式扭矩测量方法精度低、智能化低的问题,设计了一种基于LabVIEW的光电多码道扭矩测量系统,该系统通过一种差动光电多码道的测角方式转化成扭矩的测量的理念,设计码盘实现分相位均分圆周,利用相同时间内两端码盘转过的脉冲数的差异,换算成扭矩植。通过光电转换后的信号经过信号放大整形等处理,经单片机对脉冲进行计数,并进行简单计算得到脉冲差,传送到上位机,显示处理。实验证明,该系统测量分辨率高,智能化程度高。
Aiming at the problem of low accuracy and low intelligence of current photoelectric torque measurement method, a photoelectric multi-code torque measurement system based on LabVIEW is designed. The system transforms to torque Measurement concept, the design code plate to achieve sub-phase points are divided into circles, the use of the same time the two ends of the encoder turn the difference between the number of pulses, converted into torque plant. Through the photoelectric conversion of the signal through the signal shaping and other amplification, the pulse count by the microcontroller, and a simple calculation of the pulse difference, sent to the host computer, display processing. Experiments show that the system has high measurement resolution and high intelligence.
