Human Detection System for Rescue Operations.

Untimely death from natural disasters is painful but death due to untimely rescue missions from collapsed buildings is more painful. In most earthquake-flood prone areas a number of people die within the collapsed building trapped and undetected. The reasons owe to the unorganized rescue missions, etc. This paper studies an innovation in this field. The idea proposes the creation of a new device as an optimal solution for identifying the location of the person trapped inside building. The proposed device senses the volatile organic compounds that are present in the air from the building, that are produced due to interactions of staphylococcus like bacteria in human sweat (eg : 3methyl 2 hexanoic acid, octenol )[1]. The highly sensitive electronic nose senses the volatile organic components in air . The method of operation is as follows. First we collect air from various locations of the collapsed building. The collected air is feed into the device which senses the volatile organic components content in it. In addition to it, the device has a NDIR Carbon dioxide sensor which also senses the Carbon dioxide concentration in it. The following conclusion can be made from it: More the value of VOCs and carbon dioxide shows the presence of the human and also their approximate location as we are testing air from different positions in the buildings(The test is highly fast such that it does not cause any lag in the rescue mission). In addition to it these data will also help us to determine the obstacle-free path as air in the building chooses the shortest path to escape. Thus using these data collected the exact location of the trapped person can be located and the rescue missions can be organized. Thus the proposed idea is expected to more efficient than the existing rescue operation techniques and save more valuable human lives.This system can be also used in security applications for surveillance.
