Аnnotation

 

The article examines the process of monitoring fire conditions using small unmanned aerial ve-hicles (hereinafter referred to as UAVs). The object of the study is the process of remote observation of fire hotspots, while the subject is the dependence of the efficiency of detecting objects of interest and flight safety on the UAV flight altitude. The research problem lies in the contradiction between the need to improve the reliability of object detection and ensuring UAV flight safety under the in-fluence of hazardous fire-related factors, including smoke, thermal radiation, and air turbulence. The aim of the study is to improve the efficiency of fire monitoring by determining the optimal UAV flight altitude. The paper develops a monitoring efficiency criterion based on minimizing total losses, taking into account both losses associated with detection errors and losses caused by the risk of UAV loss. Mathematical models of object observability and flight safety are proposed, considering variable parameters of the fire environment, including smoke intensity, characteristics of the underlying sur-face, and thermal effects. Based on these models, an algorithm for determining the optimal UAV flight altitude for individual fire hotspots is developed, taking into account local conditions. A dis-tinctive feature of the obtained results is the comprehensive consideration of the mutual influence of observation conditions and flight hazard factors, as well as the adaptive nature of the proposed ap-proach, which enables the determination of optimal flight parameters in real time for different areas. According to the simulation results, the use of the proposed approach increases monitoring efficiency by an average of 15 %, and in some cases by up to 40–80 % compared to flights at a fixed altitude. The obtained results can be applied in decision support systems during fire response operations.
