Development of Real-Time Soil Deformation Monitoring System (RSDMS)

This research study has identified four contributing factors to the success of monitoring tasks activity by a Real-time Soil Deformation Monitoring System (RSDMS). The first factor is the ability to achieve highly accurate observation. Secondly, it is the maximum reliability of the system. Thirdly, the automatic measurement and computation factors and the least is RSDMS has emails alert function to alert undersign engineer with up to date deformation data. To meet this objective the RSDMS is being developed using Microsoft Visual Basic 6.0 which systematically measure and trace for any alteration in the coordinates of monitoring prisms which are potentially caused by soil movements. The RSDMS equipped with functions of logging measured values used for post processing, carry out deformation analysis, targets health checks and events triggering alarm thus will provide a simple, low cost and functional way to record the absolute 3-D displacements especially for a large number of monitoring points. The TM30 robotic total station is used as a geodetic measuring device in RSDMS. All the collected data are then transferred back to the server by using Files Transfer Protocol (FTP) method subsequently processed with STAR*NET, the program embedded in the system for data analysis by Least Squares Adjustment. Any adjusted coordinate differences from the initial survey data will be analyzed further by the targets health check function of the RSDMS thus sending alert emails with event details to the designated authority.
