Intelligent induction air pressure floating system for island (reef) surveying and mapping unmanned vehicle

Abstract

The invention discloses an intelligent induction air pressure floating system for an island (reef) surveying and mapping unmanned vehicle and relates to failure induction and floating automatic control technology for the unmanned vehicle. The system comprises a gas cylinder, an air bag, a central control system, an intelligent inductor, a relay air pressure valve and a power supply and is characterized in that: the intelligent inductor inducts uncontrolled drop of a platform of the island (reef) surveying and mapping unmanned vehicle and transmits information to the central control system; the central controls system processes the information, makes a judgment and sends a startup command; the relay air pressure valve automatically opens a gas cylinder valve to inflate the air bag; and theinflated air bag allows the unmanned vehicle to float on water surface. The floating system is applied to the unmanned vehicle for the first time so as to ensure that the unmanned vehicle can float on sea surface after the unmanned vehicle falls due to failure during the surveying and mapping of an island (reef) which is not easy or not suitable to reach and prevent a surveying and mapping instrument from being damaged by sea water corrosion. Moreover, search and rescue personnel can correctly lock the position range of the wrecked unmanned vehicle by a global position system (GPS) module. The system has the advantages of high degree of automation, simple structure, economy and practicability.

Description

technical field [0001] The invention belongs to the field of surveying and mapping of sea islands (reefs), and relates to the technology of intelligent sensing and floating automatic control of unmanned aerial vehicles. Background technique [0002] Due to the low cost of UAVs compared with ordinary space shuttles, failures occur from time to time, and the existing UAVs generally do not have a floating system. UAVs for island (reef) surveying and mapping mainly operate over sea areas. It will sink into the sea, causing the surveying and mapping instruments to be damaged by seawater corrosion, and the search and rescue range of the UAV cannot be determined in time. Contents of the invention [0003] In view of the above problems, the object of the present invention is to provide an economical island (reef) surveying and mapping UAV intelligent induction air pressure floating system, so that the UAV can float on the water surface when the UAV fails and falls into the sea, an...
