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。
The traditional photoelectric encoder accuracy detection using parallel light pipe and polyhedron, the disadvantage is that the detection time is long, you need to have the experience of the master; encoder error detection by rotating the encoder, the binary light row successive carry, the same monitoring efficiency , And easily wrong judgment. In this paper, a set of photoelectric encoder automatic detection system, the reference encoder, the motor and the seized encoder coaxial connection, of which 24-bit reference encoder as a benchmark for precision and position feedback components constitute a closed-loop system, DSP-based control The automatic control system of the instrument controls work in two modes, the precision detection work is in the position mode, the error detection work is in the speed mode, it can detect the precision and judge the wrong code at the same time. The system was used to test two 14-bit encoders. The experimental results show that the accuracy of the detection data is consistent with that of the collimator. The system can improve the detection efficiency and shorten the design cycle of the encoder, which can be extended to other types of encoder debugging and testing.
