Research Of Mine Power Supply Design System Based On Web

Power Supply calculation not only affects the efficient production of coal mine directly, but also the lives of mine workers. It is very important for coal mine to strengthen the management of power supply and calculator power supply scientificly and accurately, which can ensure the safe operation of coal mines and mining enterprises efficient production. With the development of information technology, Traditional power supply design software based on C / S mode reveales a series of shortcomings,such as it's difficult for software upgrades and database resources to renew,which causes substantial waste of resources, hamperes the efficiency of coal-powered design seriously,and cann't meet the coal-powered computing speed and accuracy any more. Therefore, it is necessary to develop a practical, convenient coal mine power supply design software,to improve the current mine drawbacks.Only in this way,can we improve the efficiency of coal-powered design, reduced the waste of resources of re-development, enhance the economic benefits of coal mining enterprises.Acooding to the characteristics of mine power supply system,this paper analyzes the design and calculation of mine power supply,which includes load statistics, short-circuit current calculation, equipment selection, relay setting and other calculation methods and principles. In addition, the article analyzes the two-winding transformers running in parallel operation and breakdown of the economic operation mode.Meanwhile, the article also divided transformer economic operation area.This paper analyzes the corresponding technology of system development, systems platform selection and Web server choice of principles and methods of system design. Describes the system development environment,Propose the structure and operation design of coal mine power supply system based on B / S model,introduce the development tools and programming languages of the system. After the analysis of the current status of mine power calculation software,this paper developed a web page of mine power supply by line calculation software,which is based on Windows XP Professional SP3,IIS5.1 and ASP of Microsoft,using VBscript and JavaScript scripting language,creating dynamic WEB database based on Access2003.Finally,the system was tested in all aspects,and demonstrated with an example to verify its reliability and stability.According to establishing Web-based design of mine power supply system related theoretical, this paper developes application software,the main innovations are as follows:Proposing the thought of power calculation software of mine based on B / S mode,developing a WEB-based mine power supply design software, achieving the goal of designing and calculating mine power supply in the web,making up the shortcomings of current software in C / S mode, improving the efficiency of resource using,providing some reference of mine power calculations in future software development.Establisheing a dynamic WEB database, improving update rate of database data,solving the traditional stand-alone software database update delay defects problems effectively,achieveing the goal of sharing the Internet to some extent.
