Slope Disaster Monitoring System Using Battery-Operated Wireless Sensor Network

This paper develops a slope disaster monitoring system using distributed sensors. The sensor node has wireless communication and tilt detection capabilities. Each sensor node communicates to each other and sends the corrected data to a base station, which can send an alert message to administrators in case of emergency. The developed slope disaster monitoring system is installed on a slope along the Chugoku Expressway. This first experimental study showed a significant potential of the developed distributed sensor network for detecting slope failures, but it also clarify that the wireless communication capability is sensibly influenced by relative geometric alignments of each sensor nodes. The second experimental study has begun along the Maiduru-Wakasa expressway. Since the geometric alignments are modified, we are having an improved wireless communication correspondence.
