基于CH317Q的USB长线传输设计及应用

Design and Application of USB Long-haul Transmission Based on CH317

  • 摘要: 传统的USB鼠标、键盘传输线长度不到两米, 不能满足远距离人机交互操作的需求.为解决USB信号传输距离短的问题, 本文提出了一种基于USB延长器控制芯片的方案.该方案可满足100 m的USB长线传输距离, 已经在某型测控计算机中使用, 经检验系统运行稳定可靠.

     

    Abstract: The length of the traditional USB mouse and keyboard transmission lines is less than two meters, which can not meet the needs of long-distance data acquisition and transmission. In order to solve the short distance problem of USB signal transmission, this paper proposes a scheme based on USB extender control chip. The program can meet the 100-meter USB long-distance transmission distance, has been used in a type of measurement and control computer, the test system is stable and reliable.
