Design And Realization Of Computer Aided System For Open - Pit Surveying And Mapping

With the rapid development of computer technology, database technology, internet technology and the use of geographic information systems into practical applications stage in the mine. It is significant to establish digital, informational, automation and intelligent mine for its development. The rapid development of information construction in the open pit and the size of the data involved in the production process increasingly urgent, it is needed to establish the open space management mapping information system strengthing guidance from outdoor mapping task to production.In this paper, The China Coal of PingShuo open pit space management information system as an example of Surveying and Mapping, which introduced a detailed design and description application system. The main contents of this paper include:(1) Discuss the feasibility of open space construction surveying and mapping management information system and its implementation technology.(2) Analysis of the GIS technology, GIS data management theory, digital elevation model theory, the process of system development technology of software development, and focuses on the analysis of triangulated irregular network model principle, and the system design and Implementation Based on this.(3) According to the software engineering principle of design, system design objectives and principles, design specification, the system error exception and interface were designed; using object oriented thinking method, to analysis and design the system architecture, and gives the analysis and design of function modules, database, data structure.(4) Propose and realize the calculation algorithm of triangulated irregular network model based on the top line, this algorithm solves the calculation on the slope bottom line more accurate.(5) Analysis and Realization of algorithm for calculating open step excavation volume triangulated irregular network based on the model, the algorithm can solve the calculation of Open-pit Bench excavation slope engineering, earthwork more accurate statistics.(6) The measured data as example, shows the main function of the system and the basic application. The main function of display module are measuring point plotting, crest reckoning, earthwork calculation and statistical output.Based on the LongRuanGIS3.2 platform, using Visual Studio2010 as the development tool, using C++ as the development language, we established the open mapping space management information system, the results can be used in the coal Pingshuo group limited open pit mine, shows that the system is practical, simple operation, reliable calculation etc.. The daily management of the open mapping data, maps and drawing, calculation of earthwork and other functions, improve the work efficiency of open mapping.
