YU Xue-xian · Modern Surveying and Mapping · 2014
Based on the technologies of mobile GIS,GNSS CORS,network communication and the mobile computing platform,and in order to monitor and collect the rail displacement and deformation information in real-time,the mining subsidence realtime data acquisition terminal is researched and developed in this paper mainly.Based on database technology and software engineering,the object-oriented data processing and analyzing system,used for processing and analyzing the rail displacement and deformation information in data processing centre refinly,is developed.According to the predicted surface displacement and deformation information,3Dvirtual reality dynamic model of underground mining effect on the rail and it's attaching main building structures is established to early warning.The research results provide the decision basis for train safety running and mining safety production.
