摘要
本文介绍了基于集散式监控系统中的采用中继分站实现二级或多级通信系统的设计技术 ,为提高系统的通信效率和通信速度 ,中继分站采用了双口RAM、双单片机结构 ,可以同时进行双向通信 ,现场使用效果良好。
Design technology adopting relay substation designed with dual port ram to implement two grade or multi grade communication of monitor and control system based on Centralized distribution model is stated in this paper.In order to increase communicate efficiency and speed of the system,relay substation is made up of dual port and dual single chip microcomputer,which can implement communication in dual direction at same time.The effect of usage in coal mine is good.
