基于USB接口的变电站自动化系统中通信控制器的设计

Design of a communication controller based on USB interface

变电站自动化系统中采用通信控制器负责与上位机及调度中心的通信。传统的设计抗干扰能力差,且安装不便。本设计则利用USB总线的优点,采取多种抗干扰措施保障数据通信的安全高效,并对USB传输机制作了简要的介绍。

Substation automatic system uses communication controller to carry out communication with field computer and remote computer. Anti - interference ablity of traditional design is not good, and connection is not simple. This design makes use of merits of USB, many measures have been taken to guarantee the communication reliability, and introduces simply USB transmission.
