基于NCUC-Bus现场总线的驱动信号转发装置的设计与实现

摘要

Combined with the self-developed fieldbus NCUC-Bus protocol, a driving signal transmiter which is reliabile, high speed and easy control was designed. FPGA and the FHY chip were chosen to realize the hardware platform. And according to the requirement of the signal transition among modules and the features of the fieldbus, the servo/spindle driver which have the interface of pulse or analog was used in the communication of the fieldbus, and solved the problems of low speed, complicate control, and bad performance.%结合自主研发的HCUC - Bus现场总线协议,设计了一种可靠性高、通信速率高、控制简单的驱动信号转发装置,采用PHY芯片和FPGA共同作用的硬件平台,结合模块间的信号转换要求和现场总线的特点,将“脉冲量或模拟量接口”的伺服/主轴驱动器应用于现场总线的通信方式,解决了“脉冲量或模拟量接口”驱动器通信速率低、控制复杂,且不适合长距离传输等问题.
