用GPS技术进行滑坡监测中的数据采集及控制

三峡水库2003年建成蓄水后,库区水位大幅度升高,可能引起多处滑坡等地质灾害.现在对库区的滑坡地质灾害进行无线监测的研究发展很快,其主要运用技术有GPS.为更合理地在工程运用中进行数据的采集和监测,对利用GPS技术进行滑坡监测的系统模型展开了分析,以监测中的数据采集为中心讨论了把控制引入模型的方法,在控制信号的引入和生成过程中结合了监测系统和滑坡灾害的特点,最后以软件程序模拟方式进行了在监测系统中引入控制的试验.结果表明控制信号的引入是合理有效的,在实际工程中可以发展和完善.

Data Collection and Control Discuss of GPS Technique and Its Application in Landslides Monitoring

Water level has risen considerably since the impounding of the Three-Gorges Reservoir in year 2003 and that might cause serious geologic hazards, including landslides. Primarily using GPS technique, the landslides wireless monitoring in the Three-Gorges Reservoir is developed in rapidnly. To collect data and monitor in engineering more rational, the system model of GPS technique and its application in landslides monitoring are analyzed. Focusing on the data collection in monitoring, the authors discuss the method of embedding control in the monitoring model. By connecting the character of the monitoring system and landslides, the control signal is produced. At last, the experiment is performed with analogy software in monitoring system including control. The experiment indicates that the control signal is reasonable and valid. In actual engineering, this method is made progress.
