Abstract

A drone control system for responding to abnormal situations according to the present invention comprises: a sensor unit installed in a surveillance area to collect environmental information regarding the surveillance area; a plurality of drones flying in the surveillance area, each equipped with a detection unit for detecting abnormal situations occurring in the surveillance area; a plurality of stations installed inside or outside the surveillance area, each equipped with a landing area for the drone to land and wait; and a control server that determines whether an abnormality has occurred in the surveillance area based on environmental information received from the sensor unit, and, if an abnormal situation occurs in the surveillance area, moves a drone waiting at one of the stations to the surveillance area and receives detection information provided by the detection unit of the drone. The drone control system for responding to abnormal situations according to the present invention enables a control server to automatically determine an abnormal situation based on environmental information collected in real time through sensors in a monitored area and to automatically dispatch a drone capable of immediately responding to the situation, thereby allowing for faster and more effective initial response compared to existing manual response methods. This invention is a study conducted with the support of the Regional Demand-Tailored Research and Development Project of Jeollanam-do and Jeonnam Technopark in 2024.

Description

Drone Control System for Responding to Abnormal Situations The present invention relates to a drone control system for responding to abnormal situations, and more specifically, to a drone control system for responding to abnormal situations that detects abnormal situations based on environmental information collected from sensors installed in a monitored area and, when an abnormal situation occurs, flies a drone to the monitored area to detect it. With the recent increase in various hazardous situations such as fires, intrusions, and natural disasters, there is a growing need for technology to detect these abnormal conditions early and respond appropriately in key monitoring areas, including buildings, factories, forests, and farmlands. To this end, systems are commonly utilized that install various sensors—such as smoke detectors, temperature sensors, ultrasonic sensors, and cameras—in monitored areas and transmit sensor data to a control room or operational server to determine whether an anomaly exists. Existing surveillance systems are structured such that even if an abnormal situation is detected by sensors, managers or personnel must manually verify the situation and, if necessary, dispatch to the site or manually operate a drone. This can lead to delayed responses, and there is a problem in that immediate on-site verification and action are difficult, particularly when the location where the abnormal situation occurs is large or difficult to access. Furthermore, existing drone systems rely on pre-set routes or manual control by managers, and there is a lack of integrated control systems capable of automatically adjusting drone routes based on real-time changing sensor data or automatically dispatching drones from the most efficient station.
