| 摘 要： | 为了减少绝对式光电编码器的体积,增强编码器的数据处理能力,设计了一种21位光电编码器数据处理系统。该编码器码盘采用矩阵码盘形式,分为粗码和精码,粗码12位,其中一位校正码道,精码为一周4096对线。数据处理部分采用DSP芯片和AD转换器相结合,将所有码道的信息全部输入到AD转换器,DSP根据AD转换器的值将原始信号转换为21位编码器的角度信息并显示。该编码器外径为160mm,采用自准直仪和正17面体对该编码器精度进行检测,精度均方差为1.09s。

| Abstract: | In order to reduce the volume of absolute photoelectric encoder, enhance the ability of data processing, a 21 bit photoelectric encoder data processing system is designed. The code disk of the encoder uses matrix code disk form, which has coarse and fine code. There are 12 bit coarse codes on the code disk. One of coarse code plays a role in correcting. The fine code has 4 096 pairs of lines in a circle. Data processing section adopts a combination of DSP chip and AD converter. All information in code chann... |
