摘　　要：针对数据传输系统速度、距离和稳定性等要求的不断提高,提出了一种基于低振幅差分信号技术(LVDS,Low Voltage Differential Signaling)的长距离高速串行数据传输系统。该系统结合LVDS技术速度快、抗干扰性强、功耗低的特点以及光纤通信容量大、传输距离远的特点,采用光纤来传输LVDS信号,解决了数据传输系统遇到的这些难题。对数据传输系统的设计分别从设计方案、硬件实现两方面进行了详细研究和描述,并解决了数据在传输过程中遇到的采集速度、LVDS传输速度、光纤通信速度和USB传输速度不匹配的问题。Based on constant improvement of the speed,distance and stability for data transmisson system,the long-distance high-speed serial data transmission system based on LVDS is proposed.This system,integrating the high speed,strong anti-interference,low power-consumption of LVDS technology and the large capacity and long-distance transmission of fiber technology,and adopting optical fiber technology for LVDS signal transmission,solves various problems in the data transmission system.The paper describes and discusses the design program and hardware implementation of the data transmission system.The proposed system also solves some problems including the acquisition speed,LVDS transmission speed,and the mismatch between USB transmission speed and optical fiber communication speed in the process of data transmission.
