Abstract

Sensing node network system (SNNS) is a compatible system for monitoring landslide disaster. Sensing node consists of sensors, data processing unit and wireless communication unit. In detection of landslide occurrence and grasping posture of sensing node; acceleration sensor is use. This paper describes the observation and estimation method of dynamic spatial behaviour of sensing node by acceleration signal. By monitoring the dynamic situation of the angles between acceleration vectors in three orthogonal axes, the posture and dynamic behaviour of sensing node during landslide disaster is estimated.
