| As a very important part of smart earth,smart mine is thought by more and more science researchers how to carry forward its information and intelligence,construct an intelligence,automation,green and efficient mine.There are no a uniform mine data code system that lead to less shared and utilization ratio.It is an important task for us that how to manage mine data effectively to increase the biomass utilization efficiency.Based on management status and collected mine data,the thesis investigates smart mine data coding and metadata model according to traits of data.Mine data is classified and coded to serve smart mine.Refer to the theory of metadata management reference,the paper builds a metadata base management system and a relationship between spatial data,data encoding and metadata to implement query and update.The main work of this paper is:(1)This thesis collects various pieces of mine data and researches on it.Mine data are divided into internal data and external data,internal data includes base data,subject data and other data.(2)Based on classification of mine data and learning from geographical data encoding rules mine data encoding method adopts plane and linear method to code.The code is classified into six classes,namely coarse classes,fine classes,first,second,third and four-grade according to meaning.The measured data are endowed with code.The code is composed of 14 numbers and alphabets and stands for each level class name.(3)Based on researching metadata model,it designs metadata model and use Geodatabase and SQL Server to build database.In the Visual Studio 2010 environment,by use of C# language,smart mine metadata base management system is developed by using ArcGIS Engine Developer.It realizes the function of information inquiry.By studying smart mine data encoding and metadata model.The proposed system can lay a foundation to realize data sharing function and improve utilization of data and provide more scientific classification system and management concept. |
