Design of fire monitoring robot based on multi-sensor fusion
To solve the problem that the current fire alarm system cannot be applied to the non-enclosed space in cities,a multi-sensor fusion fire monitoring robot is proposed.The robot adopts crawler structure to adapt to multi-terrain movement,and determines the construction of acquisition module according to the main characteristic parameters in the initial stage of fire in the unsealed space in the city.D-S evidence the-ory is used to fuse and detect the fire data of multiple sensors,so as to reduce the false alarm rate of a sin-gle sensor and improve the accurate judgment of fire accidents in non-enclosed spaces.Besides,the robot also carries out on-site alarm and remote return of fire.The experiment shows that compared with the single sensor judgment,the fire detection uncertainty of the fire monitoring robot with D-S evidence theory is re-duced,and the detection accuracy is improved.
