Design And Implementation Of Maintenance Information Management Platform For Large-scale Equipment In Opencast Coal Mine

In the context of the rapid development of computer technology,more and more enterprises use information systems to improve the efficiency of enterprise management and operation.As the only department of equipment maintenance and management,the equipment maintenance center of Shenhua Baorixile Energy Co.,Ltd.has a very heavy daily task.The company needs to establish a unified management platform for equipment maintenance information of the company,to achieve effective storage and analysis of equipment information and maintenance information,and to standardize the use and maintenance procedures of equipment.This paper takes Shenhua Baorixile Energy Co.,Ltd.as an example to carry out the demand analysis of the functions that the equipment management system needs to realize.On this basis,the detailed design and system construction are carried out,which are divided into the following steps: Firstly,on the basis of the demand analysis of the system functions,the framework planning of the system is redefined;Secondly,the database design is completed,with emphasis on describing the design and implementation of the important classes of the system;Thirdly,the design of input and output of the system is completed.The system is designed and implemented in detail mainly using UML top-level diagram and processing diagram.In addition,this paper also analyzes the application effect and prospects of the system,points out the shortcomings that still exist,and provides reference suggestions for future design.This system adopts the design ideas of domain-driven design,aspect-oriented programming,modular development,N-tier architecture,etc.It divides the whole platform into several functional independent modules and basic framework components,encapsulates the core business logic,integrates ASP.NET Identity to realize login authentication,functional authority authorization and verification,role and user management,and integrates Log4 Net to achieve logging;integrates Auto Mapper to realize two-way automatic conversion between Dto class and entity class;adopts Bootstrap technology to achieve a responsive layout,uses a variety of Jquery plug-ins to enrich the client experience,from the overall architecture design to the implementation of specific functions,all reflect the design ideas of a new generation of ASP.NET applications."Platform" function design is relatively perfect and can meet the actual needs of enterprises.
