Abstract


Deformation monitoring in order to monitor the deformation of the deformable surface engineering buildings and facilities and long-term repeatability of the measurement work, the key is to capture the deformation of the deformable body deformation sensitive parts and observing weeks during deformation observation point Information. Although now GPS measurement methods, photogrammetric methods, as well as other methods of measurement used in the field to better use. But the traditional conventional geodetic method is still the primary means of human engineering building deformation monitoring. In the technology field, the other technology (such as a modern space positioning technology) still can not be replaced by conventional geodetic methods. High the observation accuracy requirements of the deformation monitoring, analyze complex data processing, monitoring and data processing requires a high-precision data processing software. The same time, due to the large amount of deformation monitoring data, quality control and standardization, standardization difficult to manage, the need for data classification archival storage. Existing deformation monitoring system function can not meet the data processing and management capabilities for some projects, the need to predict the deformation information analysis, such as high-speed railway settlement assessment, therefore, the design of a set of data processing, management and forecasting analysis in one of the system is very important. This paper systematically studied the deformation monitoring network data processing methods and predictive analysis model. Improved exponential curve model based on the principle of least squares iterative algorithm, the method of calculation of the three-point method model model. And research based on space-time interpolation correction model, regional land subsidence subsidence data correction. Through the above research, using VC # NET as a development tool, MYSQL basic database system, Excel and text form as the output format of the outcome, as the graphical output format. Jpg and. Dwg format, developed deformation monitoring data processing predictive analysis system, and the system's main function is the processing and management of deformation monitoring data, upon completion of the data processing to output the full accuracy of statistical information, and on the deformation information predictive analysis, the system also provides the output function of the outcome of deformation data and the prediction information. The system consists of a data processing subsystem, the data management subsystem, graphics rendering subsystem, the predictive analytics subsystems, the results of six subsystems output subsystem and the regional subsidence data correction subsystem. On the basis of the measured data processing and forecasting analysis to verify the correctness of the data processing module of the system, and predictive analysis module is running.
