Problems solved by technology

[0004] The universality of the ranging method of the existing rotor UAV multi-fire extinguishing water bomb device is poor; at the same time, due to the multi-path interference of the GPS of the UAV, the GPS positioning accuracy error of the aircraft is very large at low altitudes, and there is no The difference between the man-machine and the take-off point can be greater than 20m, which may easily cause the drone to land in an unknown and unsafe place, or cause a safety accident

Abstract

The invention belongs to the technical field of an unmanned aerial vehicle, and discloses a multi-fire extinguishing water bomb device of a rotor unmanned aerial vehicle, a control system and method and the unmanned aerial vehicle. An operation parameter of the multi-fire extinguishing water bomb device of the rotor unmanned aerial vehicle is set by a key, image data of a flight environment is acquired by a camera, flight distance-measurement operation is performed on the rotor unmanned aerial vehicle by an infrared distance-measurement part, a wireless signal is emitted by a wireless emitter,a wireless remote controller is connected with the wireless signal to wirelessly control the rotor unmanned aerial vehicle, a rotor is used for controlling upgrading of the unmanned aerial vehicle, ejection fire-extinguishing operation is performed on airborne multi-fire extinguishing water bomb by an ejector, and the rotor unmanned aerial vehicle is controlled to do return operation by a returninstruction. The multi-fire extinguishing water bomb device is also relatively high in sensitivity and has relatively high universality; and meanwhile, the unmanned aerial vehicle can be enabled to fly under an environment with relatively large interference to a GPS multiple paths by a return module, and the unmanned aerial vehicle can be enabled to still accurately return.

Description

technical field [0001] The invention belongs to the technical field of unmanned aerial vehicles, and in particular relates to a multi-shot fire extinguishing water bomb device, a control system, a method and an unmanned aerial vehicle for a rotor unmanned aerial vehicle. Background technique [0002] Rotor UAV is the product of micro-electromechanical system integration. It has become the focus of research in many laboratories at home and abroad because of its advantages such as vertical take-off and landing, free hovering, flexible control, and strong ability to adapt to various environments. The system research of micro-rotor UAV is mainly aimed at the ground control system and the airborne measurement and control communication system. The ground control system can monitor and command the flight attitude of the UAV; In the flight state, the inertial sensor, the ultrasonic range finder, etc. are used for data collection, and these data are transmitted to the ground control ...
