Background technology
For fields such as fire rescue, building collapse rescues, when tackling fire incident, the scene of the accident, which often exists, is permitted
Hide fiery point, once omit if may resume combustion and cause second accident.These fire point positions are hidden, it is difficult to are found by people, mesh
The preceding effective means for not carrying out also monitoring in real time on a large scale to it.
Carrying out accident emergency rescue, particularly in face of the rescue work of major accident when, it is big accident scope to be often present,
Situation more than indicator of trapped personnel.Heavier, the on the point of dying indicator of trapped personnel of those injuries generally requires the relief of the very first time.But these
Severely injured indicator of trapped personnel can not often send sound, and life signal feature is extremely faint, is more difficult to send out than general indicator of trapped personnel
It is existing.And the general investigative range of hand-held vital survey meter of the prior art is small, sensitivity is not high, searches for a wide range of scene of the accident
A few hours are generally required, greatly reduce the rescue success rate of severely injured indicator of trapped personnel.
