Information Push Technology and Its Application in Network Control System

The application of push technology will change our ways of obtaining information via Internet. The paper focuses on the methods of developing the application of network and the network integration techniques. The construction of communications interface between field control network and Internet, the accomplishment of the information exchange between web database and field control network, and the technique of real-time alarm system on Web are discussed. The authors introduce an implementation mode to let the server push real-time alarming information to clients in the NCS of multiple intelligent node base on field intelligent device (LON node). It is a new mode in acquiring monitoring information, which will improve the transmission of information in NCS and the stability of the NCS.
