FIG. 6 is a flowchart showing the operation process of the drone control computer 4 in the drone according to the first embodiment.
Hereinafter, the operation of the unmanned aircraft control computer 4 according to the first embodiment will be described in detail with reference to FIGS.

When operating the drone, the user needs to set the flight path in advance or during flight.
In the drone control computer 4, the input unit 401 or the receiving unit 402 inputs flight route candidate information from the user (S601) (movement route candidate information input step). As described above, the input unit 401 inputs the flight path candidate information before the flight, and the reception unit 402 receives the flight path candidate information by wireless communication when the flight is in progress.

Whether or not the drone enters the flight prohibited area (S602) (movement path candidate determination step),
If the flight path candidate does not overlap the flight prohibited area, that is, if the drone 1 does not enter the flight prohibited area, the control instruction unit 405 instructs a normal operation (S603). For example, the control instruction unit 405 instructs the flight path setting unit 406 to set the input flight path candidate as a flight path. Further, when in flight, the control instruction unit 405 does not give any control instruction to the flight control unit 408, and allows the flight control unit 408 to transmit normal steering signals and power control signals to perform normal operation. .
On the other hand, when the flight path candidate overlaps the flight prohibited area, that is, when the drone 1 enters the flight prohibited area, the control instruction unit 405 instructs an exceptional operation (S604) (entry prohibition step). As an exception operation, for example, the control instruction unit 405 does not output the input flight path candidate information to the flight path setting unit 406 and does not set the flight path candidate indicated in the flight path candidate information as a flight path. . In addition, before the start of flight, the flight control unit 408 is instructed to perform control such that the power source 8 is locked, such as locking the power source 8, and the flight is stopped. Further, after the start of flight, for example, the control instruction unit 405 instructs the flight control unit 408 to forcibly land, and also instructs to stop the operation such as locking the power source 8 after the forced landing.
Then, the flight control unit 408 outputs a power control signal and a steering signal in accordance with an instruction from the control instruction unit 405, and performs control for locking the power source 8 and forced landing.

  As described above, according to the present embodiment, when the flight path candidate information is input before the start of the flight or after the start of the flight, by comparing with the flight prohibited area, the unmanned aircraft can enter the flight prohibited area.

In the present embodiment, the flight path candidate determination unit 404 corresponds to an example of an approach possibility determination unit.
Then, the control instruction unit 405 determines that the unmanned aircraft flight prohibited area when the possibility that the unmanned aircraft 1 enters the flight prohibited area is determined to be a certain level or higher by the flight path candidate determining unit 404 serving as an approach possibility determining unit. Take entry prohibition measures to prohibit entry into Examples of the entry prohibition measures include changing the flight path of the drone 1 to a path where the drone 1 does not enter the flight prohibited area, or stopping the flight of the drone 1.

Next, the position determination unit 409 specifies the current position and the traveling direction of the drone 1 from the positioning information (S902) (position determination step). For example, when the flight prohibition area information in the flight prohibition area database 403 specifies the flight prohibition area based on system-specific relative coordinates, the position determination unit 409 converts the latitude / longitude information from the GPS receiver 3 into relative coordinates. Process. Further, the position determination unit 409 may record the history of the position determination result of the unmanned aerial vehicle 1 so far, and collate this history information with the current position to specify the traveling direction of the unmanned aircraft 1. Further, the position determination unit 409 may determine the flight speed of the drone 1.
Next, based on the flight prohibited area information registered in the flight prohibited area database 403, the unmanned aircraft 1 determines whether the unmanned airplane 1 The possibility of entering the flight prohibited area is determined (S903) (entry possibility determination step). The determination of the possibility of entering is performed in consideration of, for example, the distance between the current position of the drone 1 and the flight prohibited area, the degree of coincidence of the traveling direction of the drone 1 with respect to the flight prohibited area, and the like.
Then, the flight path candidate determination unit 404 determines whether or not the determined approach possibility is higher than a certain level (a certain threshold) (S904). If the approach possibility is lower than the certain level, the control instruction unit 405 A normal operation is performed (S905). For example, the control instruction unit 405 does not give any control instruction to the flight control unit 408, and allows the flight control unit 408 to transmit a normal steering signal or power control signal to perform normal operation.
On the other hand, when the possibility of entering is above a certain level, or when the drone 1 has already entered the flight prohibited area, the control instruction unit 405 instructs an exceptional operation (S906) (entry prohibition measure step). . As an exceptional operation, for example, the control instruction unit 405 instructs the flight control unit 408 to forcibly change the route, or retreats from the flight prohibition region if it has entered the flight prohibition region. Instruct. Further, the control instruction unit 405 instructs the flight control unit 408 to perform forced landing, and instructs the stop of the operation such as locking of the power source 8 after the forced landing.
Then, the flight control unit 408 outputs a power control signal and a steering signal in accordance with an instruction from the control instruction unit 405, and performs control for forced change of the flight path, withdrawal from the flight prohibited area, and forced landing.

  As described above, according to the present embodiment, when a flight prohibited area has been violated or is likely to be violated during flight, the landing or the route change is forcibly performed. It is possible to prevent the drone from entering the aircraft or to move the drone out of the prohibited flight area, and to prevent the drone from being used for malicious purposes such as attacking a specific target.
