Intelligent sensing and pneumatic floating system of unmanned aerial vehicle for island surveying and mapping

The utility model discloses an intelligent sensing and pneumatic floating system of an unmanned aerial vehicle for island surveying and mapping, relating to a fault sensing and floating automatic control technology of an unmanned aerial vehicle. The intelligent sensing and pneumatic floating system comprises an air bottle, an air bag, a central control system, an intelligent sensor, a relay pneumatic valve and a power supply. The intelligent sensing and pneumatic floating system is characterized in that the system senses the uncontrolled drop of a platform of an unmanned aerial vehicle for island surveying and mapping by means of the intelligent sensor and transmits information to the central control system, the central control system processes the information, makes a judgment and sends out an enabled instruction, and the relay pneumatic valve automatically opens a valve of the air bottle to inflate the air bag, so that the inflated air bag enables the unmanned aerial vehicle to float on the water surface.
