Design And Development Of Anticorrosion Management Information System For Underground Pipelines Of Chemical Fiber Yizheng

With the improvement of the anticorrosion management level, computer management is the new inevitable trend.The anticorrosion MlS(management information system) is developed based on the anticorrosion management of underground pipelines in Chemical Fiber Co. Ltd Yizheng. The system is composed of query, forecast, design, calculate and maintenance. In the process of the development, boundary element method(BEM), artificial neural network(ANN) and the database principle were used. The system was developed with Delphi 6.0 and Visual C++ 6.0.In this paper, the following research fruits were achieved:(1)Built the database based on the principle of database.(2)Made a mathematical model for the potential distribution of cathodical protection on underground pipelines, in which the major innovation is the inclusion of nonnegligible ohmic voltage drops in the pipelines. BEM was used to calculate the values of potential, and the calculation program was obtained.(3)Improved the algorithm of BP ANN, optimized BP ANN using gene algorithm, made a mathematical model for atmosphere corrosion and soil corrosion of metal. Built the ANN algorithm program.(4) The new system was designed, and it was developed with Delphi, the reliable system was obtained.The interface of the system is friendly and the operation is convenient. The system makes anticorrosion management more scientific and systematic.
