A SYSTEM FOR ADAPTIVE SUPPRESSING THE IGNITION OF MATERIALS AND SUBSTANCES

By using a model room, the conditions are reproduced for the functioning of the system of early identifi cation of ignition originated due to the statistically most typical causes and its eff ective suppression are represented due to the timely and reliable information on the type of fi re source, its size and position, and on pyrolyzing material and its mass. The response characteristics of diff erent types of fi re detectors are recorded. Specialized software has been developed that allows accumulating statistics on the response of various types of sensors in a model room, analyzing statistical data and issuing recommendations for the fi re safety system operator. Statistical data are used by a neural network to determine the type of combustible material, its mass, material heating mechanism, and the volume of extinguishing agent necessary and suffi cient to localize and suppress combustion of the material. The proposed adaptive approach to fi re extinguishing allows one to signifi cantly reduce the amount of water required to suppress the fi re source and the time of its extinguishing.
