FEATURES OF CREATING A SYSTEM OF ACOUSTIC MONITORING OF EMERGENCY SOURCES IN THE CONTEXT OF THE DEVELOPMENT OF THE SMART CITY CONCEPT

Abstract

The basic principles of creating in the SAFE CITY model of the SMART CITY system a subsystem for controlling the city’s acoustic space are outlined, followed by the receipt and processing of information, as well as forecasting the occurrence of emergency situations of various types in the city and developing effective management anti-crisis solutions.A structural and functional model of strategic development in the general system SMART CITY of the subsystem SAFE CITY was developed (according to the IDEF0 standard), taking into account the governing flows of the regulatory and legal framework of Ukraine and the availability of relevant mechanisms (resources) in the state. In the process of modeling, it is shown that the process of registering threats to the life of the city includes the organization of a financial audit, social and environmental monitoring, video surveillance, radiation, chemical and biological monitoring, as well as spectral analysis of radiation from sources of danger. At the same time, it was established that the organization of the spectral analysis of radiation from sources of danger includes a complex analysis of the characteristics of radiation in various frequency ranges (in the acoustic, radio, infrared, optical, ultraviolet, and X-ray ranges, as well as the analysis of gamma and cosmic rays), where each of the methods analysis has both disadvantages and advantages.A systematic approach and principles of using the spectral analysis of the acoustic space of the city are proposed for the implementation of continuous and long-term operational monitoring on a real-time scale based on the place of occurrence and the dynamics of the development of identified sources of emergency situations of various nature. At the same time, it was established that the main indicator of the effectiveness of the operational acoustic monitoring subsystem of the emergency zone in the city is the reliability of the identification of the source of danger by type and place of occurrence, which depends on factors that directly characterize the dynamics of changes in indicators of the development of the source of danger, on factors that characterize tactical and technical indicators of means of acoustic space control, as well as from factors that are characterized by geographical and physical and chemical indicators of the place of origin of the source of danger and the medium of propagation of the informational acoustic signal.The system approach proposed for the creation of this subsystem and the principles of using the spectral analysis of the acoustic space of the city are the basis for further scientific research aimed at developing an effective system of ground-based automated devices for monitoring acoustic space and passive location of hazard sources.
