双座标单片微机光栅数显表

Two-coordinate axis single chip microcomputer grating digital readout-instrument

光栅数显表是一种用于精密测量直线位移量的数字化仪表。它与光栅尺传感器共同组成位移测量系统。本文系统地介绍了以单片微机为核心构成的双座标光栅数显表的工作原理、硬件组成和程序设计方法,以及该表的几个主要特点。

Grating digital readout-instrument in a kind of digital meter which is used to measure accurately straight-line displacement. Together with grating-rule sensor, it consists of measuring-displacement system.The thesis introduces systematically work-principle, hardware-composed, program-designed method and a few main character of two-coordinate axis grating digital readout-instrument at the core of single chip microcomputer.
