摘要
传统的光电编码器的精度检测利用平行光管和多面体,其缺点是检测时间长,需要有经验的师傅;编码器误码检测则通过旋转编码器,使二进制灯排逐次进位,同样监测效率低,且容易错判。文中设计了一套光电编码器自动检测系统,基准编码器、电机和被检编码器同轴连接,其中24位基准编码器作为精度检测基准和位置反馈元件构成闭环系统,以DSP为核心的控制器控制自动检测系统工作在两种模式下,精度检测工作在位置模式下,错码检测工作在速度模式下,可以检测精度的同时对错码进行判别。采用该系统对两台14位编码器进行检测,实验结果表明精度检测数据与采用平行光管精度检测数据一致。该系统可提高检测效率,缩短编码器设计周期,可以推广到其他型号编码器调试与检测中。
Traditional method is using a collimator and polyhedron shortcomings of low efficiency, which requires experienced master. for encoder accuracy detection with Encoder error detection adopts binary light bars, when rotated encoder forward, the light bars will carry normal. However, this method is inefficient, and also resulting in an error of judgment. The automatic detection system for photoelectrical encoder was designed. Motor fiducial encoder and certified encoder were coaxial. As position and speed feedback, fiducial encoder＇s resolving was 0.077″. DSP was the control core, automatic detection system was working in speed and position mode. Precision demarcating was in position mode while error checking was in speed mode. The automatic detection system was used to detect two 14 Bits encoders, comparing with collimator detection system, experimental results show that the system works effectively and properly. The accuracy detection and error code checking can be performed simultaneously, improved the detection efficiency and shorten the design cycle of the encoder. Other models encoder debugging and testing can be extended.
