Design of a fire detection system based on four-rotor aircraft

This paper designs a fire detection system based on four-rotor aircraft, aiming to accurate measure the temperature and smoke in the open area at the occurrence of fires and their secondary disasters. The detection platform was established through the analysis on flight dynamic model. The proportional-integral-derivative (PID) control was introduced to control the four rotors in all directions, so that the aircraft can fly stably in open area. A temperature sensor and a smoke sensor were installed to allow the rotors capture temperature and smoke concentration in smooth flight. Through wireless control, the values of the detected temperature and smoke and the scene picture are sent back to the control center in real time. Once the data surpasses the critical values, the system will send out an alarm. The research findings shed new light on fire detection and pre-warning of secondary disasters. © 2019 Lavoisier.
