Alexander Hamuhin received the patent for the method of forest fires detection;
he suggested to use the sensors, capable to catch a sound of coming fire on a
distance up to five kilometers, the press-service of the university informed on
Monday.
It is specified that currently used sensors detect the increase in temperature
and transmits a signal about the fire when the fire is already is in immediate
proximity to them. Sensors proposed by Tomsk scientists, will be able to catch
the sound of the fire much earlier, before the temperature starts to rise. It
will give to field services more time to respond.
"I decided to combine both thermal and sound sensors. Because the fire is
accompanied by various sounds. For example, during a ground fire the crash is
audible, and swift crown fire extends with a rumble", – the press-service
quoted Hamuhin words.

It is noted that the scientist has also developed the computer program which
allows to carry out the spectral analysis of the fire sound. According to its
intensity it is possible to draw conclusions about the fire area. Sensor design
is simple: for its work is only necessary the microphone and elements for
GPS-signal transmission in a single control center.
It is added that now the scientist expects to win a grant on further researches
which would help to carry out more serious analysis of fire sound. So, Hamuhin
assumes that fire is accompanied by infrasounds, imperceptible to human
hearing.
According to the press-service, now the scientist searches for partners for the
further project realisation. Interest have already expressed in company
"DSK" – the scientific organisation of innovative centre
"Skolkovo", which develops and implements information system of
forest monitoring.
