针对绝对式光电轴角编码器在采用CAN 总线通信方式控制系统中的应用,提出编码器数据传输接口的一种新方法,即通过CAN 总线接口实现在带有多传感器、多分系统的控制系统中数据传输,本文论述了它在大型光电跟踪系统中的应用。 关键词:绝对式光电轴角编码器,CAN 总线,SJA1000,光电跟踪系统 Abstract: We put forward a new method for the data transmission of the optoelectronic axis-angle encoder, aiming at the optoelectronic axis-angle encoder which used in the control system based on CAN Bus communication. It achieves the data transmission by CAN Bus interface in the control system having more sensors or more subsystems. Here we discuss that it can be used in the large-scale optoelectronic tracking system. Keywords: The optoelectronic axis-angle encoder, CAN Bus, SJA1000, The optoelectronic tracking system
