Drone system, drone, steering device, drone system control method, and drone system control program

Abstract

[Problem] To provide a highly safe drone. [Solution] A steering device 401 and a drone 100 that are connected to each other via a network and operate in a coordinated manner. The drone comprises: a flight control unit 23; a flight start command reception unit 51 that receives flight start commands from a user 402; a drone determination unit 53 that determines the configuration of the drone; and anexternal environment determination unit 54 that determines the external environment of the drone. This drone system has a plurality of mutually different states including at least a takeoff diagnosisstate (S5) and moves to a different state when a condition is satisfied. The takeoff diagnosis state includes at least either: a drone determination state (S51) in which the drone determination unitdetermines the configuration of the drone; and an external environment determination state (S53) in which the external environment determination unit determines the external environment. If a flight start command has been received, the drone system transitions to the takeoff diagnosis state and then causes the drone to take off.

Description

technical field [0001] The present invention relates to an unmanned aerial vehicle system, an aircraft (unmanned aerial vehicle), and in particular to an unmanned aerial vehicle with improved safety, a control method for an unmanned aerial vehicle system, and an unmanned aerial vehicle system control program. Background technique [0002] The application of small unmanned helicopters (multi-rotor helicopters) generally called drones is advancing. As one of the important application fields thereof, chemical sowing of agricultural chemicals and liquid fertilizers to farmland (farm) is exemplified (for example, Patent Document 1). Compared with Europe and the United States, in Japan, where farmland is small, it is more suitable to use drones instead of manned planes or helicopters. [0003] Through quasi-zenith satellite system or RTK-GPS (Real Time Kinematic-Global Positioning System) and other technologies, the drone can accurately know the absolute position of the drone in ...

AI Technical Summary

Problems solved by technology

[0004] On the other hand, it may be difficult to say that safety considerations are sufficient for autonomous flying drones for agricultural chemical dissemination.

Since the weight of the drone carrying the medicine is tens of kilograms, there is a high possibility of serious consequences in the event of an accident such as falling onto a person

In addition, as a rule, the operators of UAVs are not specialists, so mechanisms for error-proofing are needed, but this is not well considered

So far, although there are safety technologies for unmanned aerial vehicles on the premise of human manipulation (for example, Patent Document 2), there is no such thing as an autonomous flying unmanned aerial vehicle for responding to the spraying of chemicals for agricultural use.
