Design of Real-Time Slope Monitoring system using Time-Domain Reflectometry with Wireless Sensor Network
摘要： Slope monitoring systems using WSN is an efficient technique to track slope movements or failures. Instability in slope contributes greatly in hazards caused to lives and property in mining areas and operations. Electronic instrumentation like wire-line extensometers, piezometers, total stations etc. are used for sensing the slope stability. The available wireless monitoring systems like SSR, LiDAR, Laser monitoring techniques are more expensive. In order to overcome this, efficient and economically feasible measurement systems for slope monitoring are needed. This paper presents the design, development and field implementation of an online, cost-effective wireless system for real-time slope monitoring which gives visible warning of a possible slope failure. The system is designed on Arduino board as a platform with RF module (ZigBee) for wireless communication. Additionally, using python the database and GUI are implemented. The experimental field TDR data is also verified with the total station monitoring system.

Reliability of Terrestrial Laser Scanner Measurement in Slope Monitoring
摘要： Dense 3D point clouds provided by terrestrial laser scanner (TLS) has demonstrated significant reliability of TLS in landslide monitoring. However, existence of errors in measurement is inevitable which eventually has decreased the quality of TLS data. To concretely measure the capability of TLS in landslide monitoring, this study has performed two epoch measurements using tacheometry (for benchmarking) and TLS (Topcon GLS-2000) at Kulim Techno City, Kedah, Malaysia. Sixteen (16) artificial targets were well-distributed on the slope to determine the accuracy of the employed TLS. Results obtained revealed that Topcon GLS-2000 provides 0.006m of accuracy. However, the presence of high incidence angles in TLS measurement has limited the capability to identify the significant displacement of the targets.
