HARDWARE IMPLEMENTATION OF ENGINEERING AND TECHNICAL METHODS OF PREVENTION OF EMERGENCIES DUE TO FIRE IN THE CONDITIONS OF ELECTRIC POWER DAMAGE

Abstract

The problem of formation of complex approaches to hardware realization of engineering and technical methods of prevention of emergency situations owing to a fire on potentially dangerous objects in the conditions of damage of power supply of systems of emergency counteraction is considered in the work. The analysis of warning methods used to detect emergencies due to fire at potentially dangerous objects proved that in specific operating conditions, namely damage to the power supply of emergency response systems, known protection methods (hazard identification as its initial stage) are ineffective. At the same time, the use of alternative methods, such as methods based on the phenomenon of acoustic emission, despite their proven ability in other areas of public safety, remains highly questionable because at present there is no appropriate mathemati-cal apparatus on which to form algorithmic and procedural basis. these innovative approaches. It is to solve this urgent problem, the formation of the mathematical apparatus of engineering and technical methods of emergency prevention due to fire in the event of damage to the power supply of emergency response systems, and the above research is directed. Based on the above, the purpose of the study is to form integrated approaches to the hardware implementa-tion of engineering and technical methods of emergency prevention due to fire at potentially dangerous objects in the event of damage to the power supply of emergency response systems. To ensure this goal, the following tasks are solved: the sequence of stages of processing acoustic signals is determined; the general requirements to hardware realization of engineering and technical methods and the gen-eral functional scheme of practical realization of the demanded approach are formed. During the research the sequence of the main stages of processing of acoustic signals from the source of an emergency situation as a result of a fire at a potentially dangerous object is generalized and determined. The general requirements to hardware realization of engineering and technical methods of the prevention of emergency situations owing to a fire on potentially dangerous objects in the conditions of damage of power sup-ply of systems of emergency counteraction are formed. The general example of realization of the functional scheme of engineering and technical methods of preven-tion of emergencies in energy difficult conditions of functioning of potentially dangerous object is considered. Recommendations concerning a possibility of application of required methods in practical activity are resulted.
