METHOD FOR DETERMINING FIRE SITUATION IN THE ROOM Russian patent published in 2021 - IPC G01N27/00 

FIELD: research and examination.

SUBSTANCE: invention relates to the field of research and examination of fires and can be used to establish the seat of a fire in a room and the ways of propagation of combustion. According to the proposed method, the probable area of ​​the location of the fire center in the room is determined, the value of the demagnetization current of metal products is measured, located in the likely area of ​​the fire source, the smallest value of the demagnetizing current is determined, the actual value of the individual indicator of the degree of thermal damage for each of the metal products is determined as the ratio of the smallest value of the demagnetization current to the value of the demagnetization current of each of the metal products, mathematical modeling of the dynamics of the fire in the likely area where the fire is located is performed, the temperature value of each of the metal products is determined, the highest temperature value is determined, the calculated value of the individual indicator of the degree of thermal damage for each of the metal products is determined as the ratio of the temperature value of each of the metal products to the highest temperature value, the smallest value of the sum of squares of the differences between the actual and calculated values ​​of the individual indicators of the degree of thermal damage among all possible options for the location of the fire in the room is determined, the location of the fire in the room is selected as one of the possible options for the location of the fire in the room that corresponds to this value.

EFFECT: increasing the accuracy of determining the location of the fire source in case of severe thermal damage to building structures and interior items by the heat of the fire, as well as with uneven distribution of various combustible loads in the fire source room, taking into account the characteristic gas exchange in the room during a fire.
