DESIGN AND DEVELOPMENT OF FIELD SYNCHRONOUS DATA COLLECTING SYSTEM OF MINING AREA SURFACE DEFORMATION INFORMATION

摘要

In order to grasp the changing situation of ground subsidence and surface collapse caused by underground mining in mining area, and raise the efficiency of field data collecting, this paper's attention is paid to develop Field Collecting System Based on Wireless Communications to acquire spatial data and attribute data. The mobile devices use Web Services to synchronous data with the server. The system can get the required map from server by Map Service, it acquires high precision coordinate by making use of the GPS Differential Technology. The attribute data can be updated to the server by Web Services. The Field Collection System of Surface Deformation Information in Yanzhou Mining Area is developed on the basis of analyzing how the underground mining work affects the ground surface. The System will provide high precision, the lasted data for researching and monitoring the surface subsidence or collapse. It integrates field ascertainment and survey. That simplifies the work of data collecting and entering into the database, and meets the requirement of real-time data.
