| 摘 要： | 基于LG97L52微处理器建立了一种经济实用的光栅数字测量装置。来自于直线光栅或圆光栅的A、B相信号经过光电隔离和脉冲整形后，送到四倍频电路进行细分和辨向。然后送到CPU的T0、T1计数器；CPU读取计数值进行处理后，将测得的位移通过8279控制一组LED显示器进行显示。测量装置设有键盘，可以进行参数的设定。文中给出了光电隔离电路、脉冲整形电路、四倍频与辨向电路以及位移显示电路的详细原理图；设计了光栅信号数据采集与显示的软件流程。使用结果表明。该装置精度高、可靠性好、使用方便，具有较高的性价比。

| Abstract: | A kind of economical and practical digital measuring device for grating-scales has been built which is based on LG97L52 microprocessor.After being isolated photo-electrically and corrected,signal A and B coming from linear or orbicular grating-scales are sent to frequency-multiplying and direction-discriminating circuits and then sent to T0 counter and T1 counter of LG97L52 microprocessor.The counting values of T0 and T1 are read by CPU and the displacements are sent to 8279 which controls a set of light-emitting diodes to display.The measuring device is equipped with keyboard and the parameters can be set on it.Photo-electric isolating circuit,pulses correcting circuit,frequency-multiplying and direction-discriminating circuits and displacements displaying circuit are given in detail.The software flow-chart for grating-scales signals' sampling and displacements' displaying is designed.The results of being widely used show that the device has high accuracy and good reliability,is easy to operate and has high ratio of performance to price. |
