大直径回转体工件的直径在线测量问题是长期困扰人们的一个难题。本文提出了一种大直径工件在线高精度测量的新技术及其实现。此技术的基本测量原理是“标记”法 ,实现的关键技术是采用外设硬件计数器与 80 98单片机的内部计数器对测量脉冲进行测量。本文比较详细地阐述了这种高精度大直径测量技术的测量原理和脉冲的测量方法
Large-diameter rotary workpiece diameter measurement of online problems is a long-troubling people. This paper presents a new high-precision measurement of large diameter workpiece on-line technology and its realization. The basic measurement principle of this technology is the “mark” method, the key technology to achieve is to use the hardware counter and 8098 microcontroller internal counter to measure the pulse measurement. This article elaborates in more detail the measurement principle and pulse measurement method of this high-precision large-diameter measurement technique
