摘要：
In fiber spectroscopic telescopes, we propose a method of wire communication to control the fiber positioning nodes which are driven by two stepping motors. Taking the integration CAN control chip as main controller, the hardware of CAN intelligent node and adapter is designed to be the bottom hardware platform for the multi-motor distributed control system. The results proved that the system has good real-time performance and stability, and is able to realize not only CAN bus communication but also PC supervisory control, fundamentally meet the requirements of real-time precise position measurement of the optical fibers.
