Secondary Development Of Spur Dike Deformation Monitoring System Based On Ditest-sta202

Aim at the problem to satisfy specific requirements of the user in the application of DiTeSt analyzer for spur dike deformation monitoring, a secondary development software system is proposed without changing the original hardware structures and optical circuits. The software is mainly to process measured data, which is to fit professional real-time online monitoring. The main contents of this thesis include four parts as follows:1. Explains the principle of deformation monitoring based on DiTeSt, the technology of SBS, the working principle of DiTeSt analyzer, bring content of deformation monitoring system, and study the hardware part of system and the interface data acquisition.2. Design software of deformation monitoring system, analysis software function, bring out development program; establish structure and flow of software system, and development program database.3. Study technical route of the monitoring system and the implementation scheme of the subsystem, including call Delphi related construction, realize functions of data pretreatment, risk of extracting and risk trend analysis.4. Tests function of modes by analyses some cases, and gets results.The system has a nice user interface and suitable for engineers and technicians. The system can obviously improve the safety monitoring on Yellow River spur dikes by real-time analysis of monitoring data, and is helpful for informationalization on Yellow River embankment management.
