增量式位移传感器信号的计算机检测

The Measurement Method for Incremental Displacement Transducer by Using a Computer

提出一种实用的用计算机对增量式位移传感器进行检测的方法。硬件只用两个计数器和一个二路电平输入口。主要功能如辨向细分、抗抖动干扰、快慢速判断、变向判断、脉冲累计和细分修正等均依靠软件完成。

A practical measurement method for the incremental displacemental transducer by using a computer is proposed . This method uses two counters and a two-line input port only. The main functions, such as direction discriminating and subdividing, shaking disturbance resisting, higher or lower speed judging, direction-change judging, pulse values summing, displacement computing and subdividing ,are realized by the computer software.
