Research on remote monitoring and diagnosis system based on corba and soap/web service technology for rolling mill

As the www technology that is commonly used on the Internet at present can't solve all remote fault diagnosis, a detailed solution to the remote monitoring and diagnosis system for a rolling mill is introduced. The hardware and software structure of remote monitoring and diagnosis system is presented. The structure of the system is made up of four subsystems: online monitoring subsystem, Data servo subsystem, Database service subsystem and www server subsystem. Software module of system includes seven parts: online monitoring module, data query module, fault information query module, trend analysis module, diagnosis analysis module, engineer station module and eigenvalue query module. The system adopts B/S model and integrates CORBA technology with SOAP/Web Service technology. It makes dynamic display and traversing for a great deal of on-line data and Firewall traversal possible. It has run a long time that proves that the system interface is friendly and easy to study. It has better security, well portability, well expandability and well stability. It can judge the running-condition of rolling mill in time.
