The switching circuit 4 can automatically switch the image sent by the video camera 2, 3 by using the launching sound of the pilotless airplane.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a control device for an unmanned aerial vehicle, and more particularly to a control device for monitoring a flight situation at the time of launch and immediately after launch.

[0002]

2. Description of the Related Art In a conventional unmanned aerial vehicle control device, when the unmanned aerial vehicle fires at a high acceleration, measured values of the attitude angle, speed, altitude, etc. of the unmanned aerial vehicle are numerically or graphically displayed on a CRT by a radar or the like. By monitoring the display, the controller grasped and controlled the flight status of the drone.

[0003]

The first problem is that, in the prior art, a graph is displayed as to whether the flight status of the unmanned aerial vehicle is normal or abnormal while many measured values change simultaneously. That is, it is often difficult to judge and grasp instantly from only the information.

[0004] The reason is that when the unmanned aerial vehicle is fired, the measured values of the attitude angle, altitude, speed, and the like of the unmanned aerial vehicle greatly change instantaneously even under normal conditions.

[0005] The second problem is that in the prior art,
This means that it is difficult to capture an unmanned aerial vehicle immediately after launch in the imaging range of the camera using only the image tracking technology, or an expensive mechanism is required even if it can be captured.

[0006] The reason is that in an unmanned aerial vehicle immediately after launch, a sudden acceleration is generated by an auxiliary propulsion means such as a rocket motor until a stable flight speed is reached. Therefore, a gimbal equipped with a camera requires a high-speed image processing mechanism for following the acceleration and a motor capable of generating a large torque.

[0007] In view of the above, an object of the present invention is to provide a control device for an unmanned aerial vehicle capable of improving the operability of a controller.

[0008]

SUMMARY OF THE INVENTION An unmanned aerial vehicle control device according to the present invention measures a flight position of an unmanned aerial vehicle and controls it while displaying a numerical value or a graph.
At least one video having a gimbal to capture the launch location and the flight situation immediately after the launch, particularly when the drone controller is unable to visually check the flight situation immediately after the launch of the drone; A camera (2, 3) and a switching circuit (4) for automatically switching images sent from the video camera.

In the control apparatus for an unmanned aerial vehicle according to the present invention, when the switching circuit (4) automatically switches an image sent from the video camera (2, 3), the switching is performed using a firing signal of the unmanned aerial vehicle. be able to.

As described above, the image signal output from the video camera can be switched by the switching circuit and output to the monitor CRT of the controller. Also, since the switching of the image signal is performed simultaneously with the input of the launch signal of the drone,
It is possible to continuously and stably monitor images from before the launch of the drone to when and after the launch.

[0011]

Embodiments of the present invention will now be described with reference to the drawings.

FIG. 1 is a diagram showing a control device for an unmanned aerial vehicle according to an embodiment of the present invention. The control device for an unmanned aerial vehicle shown in FIG. 1 has a configuration including an unmanned aerial vehicle launching device 1, a launch position monitoring camera 2, a flight monitoring camera 3, and a switching circuit 4.

Two video cameras, a launch position monitoring camera 2 and a flight monitoring camera 3, are installed on the unmanned aerial vehicle launching device 1. Image signals output from these video cameras are input to the switching circuit 4. Switching circuit 4
Has an internal relay for switching image signals transmitted from these video cameras, and the switching of the relay is performed by an unmanned aircraft firing signal transmitted from a control device (not shown). The image signal output of the video camera selected by the switching circuit 4 is output to a control monitor CRT.

The launch position monitoring camera 2 is located very close to the drone launching device 1. Flight surveillance camera 3
Is located at a distance capable of following the angular velocity of the unmanned aerial vehicle at the time of launch, and is rotatable. For this reason, the flight surveillance camera 3 can stably monitor the video when the drone is launched.

In a state before the drone is fired,
The switching circuit 4 selects an image signal sent from the launch position monitoring camera 2. Therefore, the monitor CR of the controller
At T, the video before the launch of the unmanned aerial vehicle, which is shot by the launch position monitoring camera 2, is output. Here, when the launch signal of the drone is input to the drone launching device 1 and the drone starts flying, the drone goes out of the field of view of the launch position monitoring camera 2. At this time, since the unmanned vehicle firing signal is also input to the switching circuit 4 relay, the image signal input to the switching circuit 4 is simultaneously input to the unmanned vehicle firing signal and the image signal of the firing position monitoring camera 2 is output. Is switched to the image signal of the flight monitoring camera 3. By switching the image signals, the flight status of the unmanned aerial vehicle after launch can be continuously monitored on the control monitor CRT.

[0016]

The effect of the present invention is that the switching circuit automatically switches image signals output from a plurality of video cameras having different installation positions simultaneously with the input of the launch signal of the unmanned aerial vehicle. The CRT can continuously and stably monitor images from before the launch of the drone to when and after launch, and when the controller controls the flight position of the drone in the event of an abnormality, the operability is improved. The point is that it can be improved.
