Researching Of Cement Pre-calciner Kiln Simulation System Based On Web

In recent years, many cement producing lines with new technology and advanced automatic level have been built up in our country. This implies that a great deal of workers and engineers with high abilities should been trained continuously.Cement Producing Process Computer Simulation System (CPPCSS) is a highlight of 211 Engineering in Wuhan University of Technology. The Rotary Kiln System Computer Simulation described in this paper is one of the subsystems of it. The author discusses the following contents based on this system.Firstly, according to referring to a lot of references and visiting on the spot, the author study and analyze the cement producing process and its simulation technology, which includes the rotary kiln system producing process.Secondly, considering the complexity of cement rotary kiln system, we build up the models of this system with the Integration techniques of artificial neural network and expert system. The improved EBP neural network algorithm is used in this system.In the paper, author tries to integrate artificial neural network with expert system, and achieves the strong complementarity: solving the difficulty in knowledge-acquisition of ES ("bottle nee') by ANN' s excellent capacity of self-organizing, self-learning and self-adaptation, and the weakness of ANN on knowledge-representation ("black-box") by the valuable explain-function of ES.In the modeling process, the selection of the input and output variables is very important, according to referring to a lot of references and visiting on the spot and considering the applicability and representative of the simulation system. We carefully select nine inspection parameter as input variables of the artificial neural network and five controls parameter as output variables. The author consider that the selection method is enough to meet the requests of the simulation and producing control with variant of the pre-decomposing rotary kiln system. According to the difference of the stylebook data, we deal with the stylebook data by pretreatment. Based on this method, and according to the data gathering from the producing spot, the author trains and researches the neural network. The results indicate that the method was efficient.Further, the paper introduce the transfer of MatlabS.l by VB and the management of the expert rules database and the Fault Diagnosis of the pre-decomposing rotary kiln system.Thirdly, the author analyzes and researches this system in detail. And the whole simulation frame of it is introduced. The simulation frame based on Web and C/M/S structure and the method of the system software development are discussed in this paper.Fourthly, the three-dimensional models of the simulation system based on 3D Studio MAX and VRML are introduced and shown. And then, the transform method between 3D Studio MAX models and VRML ones is applied in this paper.At last, the author summarizes the whole paper and points out the future direction of the development of the system.The research in this paper not only has important theoretical and practical values in cement and other industries, but also makes solid basis to the post-development of CPPCSS.
