A method for automatically detecting the initial stages of fires in the premises of fire hazardous facilities containing fuel equipment

摘要

FIELD: fire safety.SUBSTANCE: invention relates to methods for providing fire safety in premises of hazard locations containing heat-generating equipment and can be used in shipbuilding in ship fire and temperature alarm systems to detect fires at the initial stages of their development. A lot of controlled physical parameters on the object are grouped together, each control parameter in the group is assigned a serial number; on each control cycle, the numerical values are formed from the obtained parameter values in accordance with their sequence numbers, which are stored and in the subsequent control cycles are compared with the newly generated numerical series, which, in case of a mismatch, is also remembered for subsequent comparison, in this case, the memorization of new numerical ranges in accordance with a number of rules is performed during the period of training and self-adjustment, after the end of which, when a numerical range different from the memorized ones appears, signal about the occurrence of the initial stage of a room fire.EFFECT: technical result consists in the expansion of the functional capabilities of fire and temperature alarm systems in terms of detecting the initial stages of the formation and development of fires by implementing training and self-adjustment functions with automatic adaptation of the systems to the features of the hazard locations and changes in operating conditions.1 cl, 2 dwg, 2 tbl
