引黄工程计算机监控系统中的数据通信规约

Data Communication Convention of Yellow River Water Drawing Engineering Computer Monitoring System

介绍了引黄工程WAN结构和配置,提出了引黄工程计算机监控系统中数据通信的分层分布式结构模式,其通信协议采用TCP/IP协议,传输层的数据格式为DNP3.0,现地层采用现场总线和RS LINK通信协议。这些协议的开放性以及现地协议的实时性,既满足了引黄工程后期建设对计算机监控系统开放和可扩充的要求,又实现了全线自动调度调节以及现地实时控制的功能。

WAN structure and configuation of Yellow River water drawing engineering is presented,and hierarchical distributed structure mode of data communication in Yellow River water drawing engineering computer monitoring system is provided ,in which TCP/IP is adopted as communication protocol data format Of transmission layer is DNP3.0,and the present ground layer adopts the present bus and RSlink communication protocol. The open characteristic of these protocol and reality of the present ground protocol satisfies not only the requirements of opening and expending of computer monitoring system in the later period of construction of Yellow River water drawing engineering,but also implements automatic dispatch adjustment on the whole line and the function of the present ground＇real time control.
