摘　　要：转台上的数据一般采用机电滑环传输至转台之外的主控计算机。本文提出了一种基于DSP和光纤滑环的光纤数据传输系统的设计方案。系统以DSP为数据处理控制核心,CY7B923/933为高速串行数据通信芯片,利用了DSP的强大数据处理能力和光纤的高速数据传输能力,实现了计算机和DSP之间通过光纤滑环进行实时数据传输。利用光纤传输的波分复用技术,实现了在一根光纤上同时传输多路数据。实验表明,该方案能极大地提高数据传输的可靠性和实时性,并可推广应用于类似的旋转机械间的通信。The data on the turntable were always transmitted by electromechanical slip-rings to the main control computer.A kind of optical fiber data transmission system based on DSP and optical fiber slip-rings was proposed in this paper.This system included the following techniques：using DSP as the controller for data processing,CY7B923/933 as physical layer chips for high-speed serial transmission.This design realized real-time data transmission between computer and DSP.Multi-channel signals were transmitted at the same time in a single fiber by using WDM（Wavelength Division Multiplexing） technology.The experiment indicated that this sys-tem could improve the reliability and increase the data transmission rate.This system can also be applied to the communication of similar rotative mechanisms.
