Design and implementation of a real-time slope monitoring system based on Ubiquitous Sensor Network

The casualties due to slope failures such as landslide, rock fall, debris flow etc. are about 24% in total casualties caused by natural disasters for the last 10 years in Korea. And these slope failures in Korea are focused in the season in which typhoon and torrential rain take place. Not much attention, however, have been put into landslide mitigation research. Meanwhile, USN (Ubiquitous Sensor Network) forms the self-organization network, and transfers the information among sensor nodes that have computing technology ability. Accordingly, USN is embossed a social point technology in Korea. Therefore, a lot of study is progressing about practical use of data which was gathered by sensors. The objective of this paper is to design and implement a real-time slope monitoring system using Ubiquitous Sensor Network (USN) technology. For this we develop module that collects and change slope movement data measured by two tiltmeter and a tension wire, store transferred data in database. Also we develop application program that can easily analyze the data. We apply the prototype system to a test site at KICT for testing and analyzing the system's performance.
