DEVELOPMENT OF A DISTRIBUTED DISASTER DATA AND
HUMAN LIFE SIGN PROBE SYSTEM

• Abstract
• This paper deals with a novel sensor
  network system designed for gathering disaster
  information including physical environmental
  information and potential signals of survivors.
  The system consists of numerous sensor probes and
  a central database server. The sensor probes
  organize their own ZigBee network, which is
  managed by the central database server. The
  server is connected to the Internet to be able to
  provide total disaster information worldwide.

• Existing system
• Presently disaster management is done
  through seismometers around the area obtain
  immediate earthquake information for reducing
  damage. It may be enough to obtain general
  condition of earthquake over area, but too small
  to collect information with fine granularity such
  as data of each building for effective rescue
  operation or damage control. There are several
  preceding researches whose objectives are close
  to ours proposes an earthquake information system
  using laptop PCs which equip accelerometers Some
  of another research groups uses mobile smart
  devices.

• Disadvantage
• As a result, the existing proposal gets very few
  data which have been helpful in finding disaster
  management.
• In other systems the internet is used as primary
  and only communication channel. This leads to
  breakdown in local internet will makes the break
  in communication.

• Proposed system
• This system consists of two parts. One
  is the central database server that collects and
  stores information from distributed sensor
  terminal, and then, provides them to clients via
  the Internet. The other is a sensor network which
  is formed by numerous sensor probes that are
  placed in buildings. The sensor probe consists of
  gas sensor, temperature sensor and accelerometer
  to gather the required parameters. The
  accelerometer is used to find seismic action, the
  gas sensor to find any leakage of harmful or
  flammable gas and the temperature sensor to find
  temperature around the probe. The system forms a
  wireless network to transfer information of each
  probe up to the central server. We employed
  ZigBee wireless technology for this network as
  mentioned in the previous section.

• Advantages
• These 3 sensors are available as convenient
  modules in the market and easily connectable to
  MCU.
• The critical levels of the hazardous gases such
  as LPG in the buildings have been indicated
  through alerting unit.
• The system successfully detected the primary
  appearances of earthquake.

• Conclusion
•   In this paper, a new development of a
  disaster information system for helping effective
  rescue operation is introduced. It is aimed to be
  useful when a disaster occurs. The sensor probe
  is supposed to be small and low power consuming.
  It also need to be robust against failures of
  ordinary power and communication lines. Thus, we
  employed ZigBee wireless communication technology
  for the communication channel of our device. Our
  current interest is to implement them into the
  device. Accelerometer sensors are simple and
  powerful physical motion sensor that can
  relatively easy to implement in both aspects of
  hardware and software. Gas sensor is also helpful
  to estimate status in the building. Moreover, it
  provides not only vital sign of human, but also
  fire, leakage of gas and etc.
