摘要
针对RTU集中式数据测控的传统方式,提出了基于网络数据集中器NDCU的网络化测控系统。由嵌入式586PC机等组成的NDCU具有多种接口,支持MAC、TCP/IP等协议规范,及相应的传输规约转换,下行汇集了多达16个RTU,上行与以太网相连。
Facing the traditional measure-control system, this article presents the Ethernet system based on the network-data concentrator ie. NDCU which is comprised of embed 586PC. NDCU realizes the interfaces among several different sorts of measure-control terminals, sustains the standard protocols, such as MAC, TCP/IP, and performs the transformation of communication stipulations.
