摘要
本文介绍一种以单片机为基础的智能光栅测量线路,它在单片机中进行软件细分,分辨率高,细分数能随光栅尺精度的不同,通过改变软件很方便地进行改变。单片机对光栅尺以及光栅测量系统中的常值误差进行了软件补偿,对系统的随机干扰进行了线性滤波,并设置有故障诊断软件。配备的串行标准RS232C通用接口和数显接口,可供同时进行数显和与其它计算机通讯。
In this paper a intelligent measuring system of grating is introduced. The system which is based on a single—chip computer makes graduation in software, so distinguish—ability of graduation of the system is very high, the value of graduation can be easily varied by changing program. In the system the contant error of grating and measuring circuit has been compensated in software, the random interference is filtered by liner lilter, and fault diagnosis programs are programmed. The system provides a RS232—C interface and a digit displsy interface, it can make digit disply and transmission at the same time.
