Infrared image system for fire location

This paper describes a new sensor and interpolation technique for localizing a fire in a closed environment or in a highway tunnel. When a smoke detecting device warns for a presence of a fire, two thermopile arrays images are elaborated, to localize the, eventual, fire and to control fire extinguisher jet. This system is a very promising for highway tunnel and also as substitute for common fire sprinkler systems in closed rooms, due to its cost and relatively simplicity of installation.
