[0002] Fires often occur in our daily lives, causing great losses to our lives and property. During the rescue process after a fire, when trapped people cannot evacuate through the safe passage, it is usually necessary to break the windows and rescue the trapped people through the windows. Nowadays, people usually install protective windows on windows to prevent theft. Therefore, it is necessary to break the protective windows in and out. In the traditional breaking process, the firefighters need to be lifted to a certain height with a lifting bracket and then manually break the window. At this time, air enters, and when the combustible materials come into contact with the air, fire will spray out of the window, thus burying a great safety hazard to the lives of the firefighters. Therefore, using drones to break the protective windows can ensure the safety of firefighters. However, the firefighting drones need to be stored after use.
