Abstract: Inorder to promote the integration of control network and information network, and the integration of management and control systems in enterprises, research is conducted on the network integration based on wireless Internet technology. An implementation scheme mainly using WAP (wireless application protocol) technology is introduced. Meanwhile, XML, which has outstanding extensibility, is applied to extend the data exchange of automation system into Web layer. This scheme is useful for the integration of control network with information network, the combination of supervisory network with Internet, and the extension of the wireless applications above field level. It is consistent with the trend of openness and wirelessness in enterprise network systems. Finally, an application in Nanjing Port is presented as an example.
