Design And Implementation Of Commercial Coal Quality Management System Of Shenhua Ningxia Coal Group

At present,the coal industry generally adopts the principle of quality pricing.Therefore,the quality of coal has become an important prerequisite for the survival and development of enterprises.In recent years,Shenhua Ningmei Coal Group thinks highly of the management of coal quality of commercial coal,actively promotes the informatization construction of commercial coal and coal quality management of the entire group.Based on the analysis of the coal quality management requirements of the Shenhua Ningmei Group,the paper combines the geographical distribution of the factories and mines of Shenhua Ning Coal and the current status of network construction,and uses the excellent design patterns,framework technologies and techniques of the open source community at home and abroad to design a four-layer system.It is based on the B/S architecture to solve the problem of regional decentralization,used MVC idea to separate business logic from underlying database access,through the combination of JSP+Struts2+ Spring+myBatis implemented the four level framework of the system:presentation layer,control layer,business logic layer,data persistence layer.In the development process,it is logically divided into action,service,Dao and domain layers,such like this layered development model,can achieve separating accessed of data and business,the loose coupling between the various levels,not only makes the development efficiency significantly improved,but also conducive to the maintenance of the system later.The Shenhua Ningmei Coal Group has a large number of departments involved in coal quality management,and the subordinate production units and departments are constantly changing.At the same time,the constant emergence of new technologies requires the system to have certain extensibility on the basis of the existing functional modules,so the system is proposed to have the design philosophy based on the disparate,templated subsystem functional configuration.The analysis of Shenhua Ningxia Coal Group and coal-related organizations,the system can be divided into five subsystem functional frameworks:coal mine framework,coal washing plant framework,quality inspection center framework,quality inspection department framework and group company production technology Department framework.The author chose ’Oracle’ as a database management system and used ’Myeclips’ as a research and development platform to develop a commercial coal quality management system.Finally,it conducts functional tests and stress tests.The research in this paper has important practical significance for the commercial coal quality management of Shenhua Ningmei Group.The implementation of the system promoted the transformation of the corporate coal quality management model of the company,achieved digital and information management,greatly improved the company’s commercial coal quality management,and laid the solid foundation for greater success and economic benefits in the long run.
