The society is constantly evolving. In terms of various cities at present, the incidence of fires and the difficulty of firefighting are gradually increasing. Before conducting fire extinguishing and rescue operations, it is necessary to conduct timely investigations of the disaster situation. The traditional investigation methods mainly involve visual observation or inquiries nearby. As the difficulty and terrain of fires become increasingly complex, these methods are no longer applicable. Subsequently, methods such as single-person image transmission and satellite image transmission emerged, but they are also affected by signals, terrain, and building structures. The appearance of drones has precisely solved the drawbacks of these methods, and can play an auxiliary role in fire extinguishing and rescue operations. For example, multi-angle shooting and real-time image transmission, etc., which greatly improve the timeliness of fire extinguishing and rescue operations. 

Drones are unmanned aircraft that are mainly controlled via radio. They are mainly composed of four parts: the platform, the flight control system, the radio remote control system, and the equipment. They can perform functions such as reconnaissance, image and audio transmission, and item placement. The interior of the drone integrates various scientific and technological disciplines, such as measurement and control, aerospace, and new energy. Drones can be classified into two types based on their users in the field of firefighting: electric and fuel-powered. The driving force of the electric drone is lithium batteries. The disadvantage of working based on lithium batteries is that the working time cannot be continuous. Once the lithium batteries are exhausted, the drone cannot continue to work. However, usually, in case of accidents, it generally does not cause additional fires. While the fuel-powered ones usually use diesel or gasoline for propulsion. They have strong continuous working capabilities, but their limitation is that if there is an accident of crashing, it is very likely to cause additional fires, intensifying the fire situation and making it difficult to extinguish. Therefore, they must be used with caution.
