基于无线互联网WAP技术的工控信息网络集成

Integration of Industrial Control Network and Information Network Based on WAP Technology of Wireless Internet

以促进企业控制网络和信息网络的集成、管控一体化为目标,研究了基于无线互联网技术的网络集成,给出了以WAP(无线应用协议)技术为主的实现方案 同时,采用扩展性很强的XML标记语言把自动化系统的数据交换扩展到Web层面.该方案有利于控制网络与信息网络、厂级网络与Internet的整合,扩展了现场级以上的无线应用,符合企业网络系统开放性和无线化的发展趋势.最后,给出了江苏南京港的应用实例.*

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.
