he hierarchical network SCADA communication model for the SCADA system in the wide distributed network is introduced in order to enhance the stability and the maintainability of the applied system,and solve the problem of developing the information and automation system with high ability and real-time processing in the realm of communication,electrical power,petroleum,chemical engineering,and manufacture etc.,and gathering together and connecting the subsystems level by level artificially.This communication model is built by using of the communication technique of data query for Client/Server mode based on the TCP/IP protocol and data transfer for peer to peer.The software product which is developed on this communication model shows that it is very easy to construct the SCADA system in the physical computers distributed in different domain,and carry on high-efficient real-time communication within the different physical computers.A kind of new efficient method is explored for the design and development of the centralized SCADA system in the wide distributed network with multi-level architecture by this communication model.
