The Unified Description Method And Model Design Of Coal Mine Supervision And Supervision Information

At present,the national safety production situation is generally stable,but dangerous accidents and major accidents have occurred from time to time in the near future,and safety production is still in a period of climbing and passing hurdles.It is necessary to vigorously prevent and resolve outstanding problems that impact the safety bottom line.In particular,the rapid development of information technology has provided a basis for improving the effectiveness of informatization supervision based on "Internet+safe production",conducting the whole process management and monitoring of all production links,and realizing real-time risk monitoring and early warning.Coal mine safety production is a key area of mine safety supervision and supervision.How to efficiently carry out coal mine safety supervision work is the focus of current government supervision and supervision departments,academia,and industry.The thesis conducts research from two aspects.Establish a coal mine supervision and supervision law enforcement process,and then,based on the problem that data cannot be managed in a unified manner in the law enforcement process,proposes a unified description method of "Internet+" coal mine supervision and supervision information.The method includes the classification code identification of supervision and supervision information,and the overall metadata model of the unified description method of "Internet+" supervision and supervision information.The classification of supervision and supervision information specifically includes the basic principles of law enforcement classification set by the coal mine supervision and supervision law enforcement category,The category setting of the main classification table and the category setting of the multiple classification table,and then the establishment of the basic law enforcement classification of the classification and coding of the basic data set of coal supervision and supervision and law enforcement.The specific process of the coding and identification of the supervision and supervision information is first through the study of the basic data set coding and basic coding Basic principles to further establish the classification and coding of data elements at the management level.The overall metadata model of the unified description method of supervision and supervision information includes:law enforcement metadata,the relationship between data elements and other data concepts,data model design,and a database of general model law enforcement.Metadata constructs law enforcement core metadata,law enforcement data elements,and law enforcement data set metadata;the relationship between data elements and other data concepts establishes law enforcement data element attributes and law enforcement data element descriptors;data model design establishes law enforcement data model design and class Relational model design,ontology model design,conceptual data model design;application scenarios for general model database establishment,general model connection related data,syntactic heterogeneous solutions of database adapters,data migration of different source database systems,of processing query requests the process.By the general topic cloud display platform of the research results of the unified description method of supervision and supervision information is given,combined with software engineering methods,and the display of research results on the cloud platform is given the design of functional modules,system use cases,database table design,ER model,data dictionary,prototype design,and system page display,etc.During the research process of the subject,through the coordinated application of the general subject and other sub-projects,the unified description method of the supervision and supervision information for the research and design of the thesis is easy to understand,Easy to use,and easy to expand at the same time.
