<p>PURPOSE:To sense a vital body overwhelmed by smoke due due fire etc. effectively by performing sensing through scanning of far infrared rays in a specific wave-length range. CONSTITUTION:A vital body image sensing device A comprises an infrared radiation thermometer 1, which senses far infrared rays of a vital body (victim of accident) and converts into electric signal in accordance with the energy of the infrared rays, and a scanning mirror 3 mounted in a scan driving device 2 of galva-scan system etc., and is installed on the ceiling 4a of a room 4. This scanning mirror 3 is located ahead a sensing window in the infrared radiation thermometer 1. Because the thermometer 1 senses only that one point in the room 4 which is focused by an internal lens system, sensing points are scanned one by one with the scanning mirror 3 ahead the thermometer 1. The temp. distribution obtained by this scan is measured, and victim 5 overwhelmed by smoke in the room 5 is sensed. The scan ray signal obtained is sent for example to a monitor device 7 of a central monitoring room 6, and the total situation of the room 4 is displayed as image data based on the temp. distribution.</p> |
