Rolling Process Tension Control System, Remote Monitoring And Diagnostic Research

The tension control system which is used for controlling the tension of rough steel is the important system in the whole rolling mill product line, and the variety of tension is the important factor that can affect whether the running process is normal or not. So it is necessary to monitor the product state and diagnose faults in order to prevent the grave faults or accidents from happening and ensure the successful running of the process, further more, it has significant benefit on increasing the enterprise management level and ensuring the quality of products.This paper will firstly sum up the faults and its related signal symptoms through the analysis of the tension control principle of the line and the research on the spot. Secondly, according to the fact, it brings forward the method that abstract the signals' state characteristic value which is used for recognizing the signals' state. On this base, the paper has adopted the fuzzy judging method to diagnose the faults of this tension control system, and the practice has indicated that the efficientof the diagnosis method is that it doesn't need any factual fault cases and it can easily build therudiment of the reasoning system by gaining some expert experiences, so it is the workable way at the beginning of setting up the diagnosis system.In addiction, we can know that applying the modern long-distance technique to monitor and diagnose has clear actual application worth on the base of the analysis of the development state of the remote monitoring and diagnosis techniques for equipments around the world. Because of the spot facts and the needs of users, so this paper introduces that applying the new ASP.NET and SQL Server database techniques to develop a B/S mode remote-monitoring and faults-diagnosis intelligent system, and it will accumulate experiences along with the continuous running, so it will gradually meet the users' needs of monitoring and diagnosis of the tension control system. Moreover, the paper has introduced the system structure, the function modules, the information structure and so on of the whole diagnosis system, and presented the whole running process of the system by an instance.At last, the research is summarized, and the paper has prospected for the future further research and pointed out the things which need to be improved and perfected in the system.
