摘要
针对以往调度模拟盘控制系统采用非智能化功能单元、并行传输方式所带来的种种弊端,例如:易受到干扰、接线复杂、不能实现显示单元自检及动态潮流方向显示等,本文提出一种基于RS-485总线的解决方案。
Quite a few problems were apt to be brought in the control system of dispatch simulative board by adopting non-in-telligentized function unit and parallel transmission in the past. For example, signal is easy to be disturbed,connection is very complex,system can not accomplish display unit self-checking and dynamic flow direction displaying.This paper has offered a solution based on RS-485 bus.
