摘　　要：为提高测试效率,设计了一种便携式高分辨率转台。首先,采用对比法搭建了误差标定平台,并采用图像角位移识别技术,设计了高精度角度基准。然后,采用直流电机带动被测编码器与角度基准同轴连接,搭建了光电编码器误差测试系统。最后,将各功能的实现代码分布在多个任务函数中,并基于μc/os操作系统对任务函数进行调度,实现合理的误差测试、显示及人机交互。实验表明:所设计的误差测试系统能够精确实现对编码器产品的误差标定,具有操作方便、便携、可靠等优点。In order to improve the test efficiency,a portable high resolution turntable was designed.Firstly,the error calibration platform was built by contrast method,and the high precision angle datum was designed by using image angular displacement recognition technology.Then,a photoelectric encoder error measurement system was built by using DC motor to drive the measured encoder to be coaxially connected with the angle reference.Finally,the implementation codes of each function were distributed in multiple task functions,and task functions were scheduled based on the operating system ofμc/os to achieve reasonable error testing,display and human-computer interaction.Experiments show that the designed error testing system can accurately calibrate the error of encoder products.It has the advantages of easy operation,portability and reliability.
