Integrating Geophone Network to Real-Time Wireless Sensor Network System for Landslide Detection
[attachment=25323]
INTRODUCTION
Natural disaster such as landslides, debris flow,
avalanches, earthquakes have gained importance as a
subject for monitoring in recent years. The main aim of such
a monitoring is to understand the way they occur and
possibly predict their occurrence. An advanced warning of
such an event could help in taking emergency measures like
evacuation of the area, blocking the traffic or human
movements in the disaster prone area.
RELATED WORK
Zan et al. deployed an early warning system for
landslides where they have used geophone for sensing the
seismic noise [2]. The paper elaborates the data acquisition,
data management and warning issued through mobile
phones, local alarms. Terzis et al. details a method for
localization of slip surface using WSN [3]. They used
DESIGN OF WIRELESS GEOPHONE SYSTEM
Disastrous events such as landslides, earthquakes, debris
flow and avalanches involve movement of soil or snow
layers. This will generate ground vibrations that travel
through the surface of earth. These signals can be captured
efficiently using geophones. Geophones are self-excited and
this is one of the main advantages for long term monitoring.
A geophone is a transducer which senses a vibration and
converts it into a relative electrical signal. The electrical
signals from the geophone are enhanced and transmitted
through the wireless network. These data are stored and
analyzed in the data management center at our University.
geophones to analyze distances between the sensor columns.
ARCHITECTURE OF WIRELESS GEOPHONE SYSTEM
Wireless geophone network is designed to incorporate
with the existing real-time wireless sensor network for
landslide detection system [1] at Munnar, India. The
existing system consists of 20 wireless sensor nodes and 50
geological sensors that are capable to monitor the changes in
moisture content pore pressure, and movement. The system
is 24/7 operational and capable to deliver real-time warnings
via internet and local alarms. The proposed Wireless
Geophone Network (WGN) is capable to capture the slope
instability vibrations and these data will contribute in
issuing a reliable landslide warning.
