Design And Implementation Of Web-based Coal Quality Infomation Management System

In the long-term process of coal exploration,construction and production,a large number of coal quality data have been accumulated.These data have not been uniformly and effectively managed,multi-source heterogeneous data standards are not unified,information is isolated and not fused,and the in-depth value of data has not been explored.As one of the fastest growing emerging technologies in recent years,web technology has derived many related theories and technologies,and continues to push through the old and bring forth the new,leading the trend.Therefore,the establishment of a web-based coal quality infomation management system can store and visually manage a large number of coal quality data,establish a variety of data search mechanisms to support decision-making management,and provide data support and decision-making support for relevant management departments,enterprises and academic activities,which is of great significance to ensure the strategic security and green development of national coal resources.This thesis studies the design and implementation of Web-based coal quality infomation management,and designs and develops the system according to three-tier architecture: front-end development language and framework to build the presentation layer,Node JS,Express and Web GIS technology to build the business logic layer,My SQL database to build the data access layer,so as to realize the information management of coal quality data based on Web.After consulting a large number of relevant literature and understanding the research progress of coal quality infomation management system and related technologies at home and abroad,this thesis analyzes the functional and non functional requirements of the system;Formulate the design objectives and principles of coal quality infomation management system,and put forward the functional process and functional structure of the system combined with the current mainstream web technology and architecture design;Sort out and collect the coal quality data collected from different mining areas in all provinces and autonomous regions,and after summary and processing,unify the database table structure and meet the data standard,and design the coal quality data summary table and coal quality data geographical location table;Based on the actual situation of system users,the user information table is designed.Finally,the previous research and work are summarized,and a web-based coal quality infomation management system is designed and implemented.Its functions mainly include user registration and login,user authorization and management,coal quality summary data management,coal quality geographic data management,multiple standard composite query,Web GIS two-way query and web map service release.Completed the user’s convenient management of coal quality data,established a variety of query mechanisms to support decision-making management,and expanded many functions to improve the user experience according to the system design and development principles.
