Development Of Real Time Data Acquisition Terminal System For Surface Deformation Of Mining Subsidence

Coal security issues becomes more significant.To ensure the safety of coal mining, we need to establish a monitoring point above the Mining Area to monitor the moving the area to for mine mining subsidence. By monitoring point data mining analysis, to ensure the safety of mine.Currently monitoring point for data collection, processing is mainly by artificial manner, usually inefficient and prone to processing errors during data collection, data monitoring points will lose authority.In the current environment of promoting coal mine safety mining, The development of data acquisition terminal system to improve the efficiency of monitoring point data acquisition, to ensure the accuracy of the data and the timeliness of the processing is of great significance.In this paper, the system is based on the PDA platform, VS2008 platform for the development of the C# language, realized the Bluetooth and the serial port and the measuring instrument to carry on the correspondence, based on key technologies Ntrip network RTK positioning and GPRS network data security transmission, Realize the file module, data acquisition module, coordinate conversion module and other functional modules of the integration, follow the efficiency, stability and reliability principles, ground movement and deformation in mining subsidence data collection terminal system design.The system can be connected to the measuring instrument via Bluetooth and serial connections, with strong visibility, centralized management of data and network data transmission characteristics.Fast data collection and mapping, the system has real-time mobile and data transmission to ensure the accuracy and reliability of the information, to achieve the integration of mining subsidence monitoring information collection points inside and outside the industry and has improved the monitoring point field data collection work efficiency.
