为提高传动系统位置检测的精度和安全性以及减小系统首末端的位置偏差,提出了绝对式光电编码器和旋转变压器的双位置解算方案。基于高速芯片TMS320F28377S设计了绝对式光电编码器和DSP的通信电路,运用SCI模块与光电编码器通信;设计了旋转变压器与DSP的接口电路,对旋转变压器的输出信号进行160倍过采样并相敏整流;分别在传动系统首端和末端安装绝对式光电编码器和旋转变压器,位置解算结果相互验证,确保传动系统位置解算的正确性和安全性。实验表明该方案能快速准确地实现位置的检测,提高传动系统的性能。
In order to improve the accuracy and safety of the position detection of the transmission system and to reduce the position deviation,the dual position solving method of absolute photoelectric encoder and resolver was proposed.Based on the high-speed chip TMS320 F28377 S,communication circuit of absolute photoelectric encoder and DSP was designed,the SCI module was used to communicate with the encoder; the interface circuit between the resolver and the DSP was designed,and the output signal was sampled over 160 times and phase sensitive was rectified; The encoder and the resolver were installed at the first and end of the transmission system respectively,and the position solving results were verified mutually,ensuring the correctness and safety of the position. The experiment shows that the method can detect the position quickly and accurately,and can improve the system＇s performance.
