Research And Implementation Of Coal Preparation Data Processing System Based On Web

Coal is main energy in China, and coal preparation is an effective technical means to improve the quality of coal, in order to improve the efficiency of washery,this paper presents a web-based coal preparation data processing system.Object-oriented software engineering method is used to describe the problem. What's more, UML modeling language and modeling tool Microsoft Visio 2000 are also used to describe system static structure and dynamic behavior. System pages were designed with DHTML, the behind code is C# language, a product of .NET, and the drawing is perfected by GDI + technology matched with .NET. System is developed under environment of .NET Framework and ASP.NET + ADO.NET, and Microsoft SQL Server 2000.Firstly, the system process the experiment data and plot raw coal washability curve,and then provide index query to help user to evaluate the washability of raw coal. Secondly, calculation of three evaluation criteria, data verification, curve drawing, form filling in, and so forth according to gravity separating equipement for coal performance evaluation.The whole system is designed to B/S structure of the three-tier structure, not only providing quick and accurate way to process experimental data, but also reducing software maintenance costs and improving software portability and flexibility.
