Abstract

An unloading arm manipulation training device is provided. The device includes: a frame having a training space inwardly; at least one screen which is provided in the frame and onto which an unloading arm training image is projected; and at least one image output unit that outputs the unloading arm training image toward the screen, wherein the at least one image output unit is provided outside the frame to output the unloading arm training image toward an outer surface of the at least one screen, thereby preventing a trainee located in the frame from being projected on the at least one screen.

Claims (24)

1 . A device, which is an unloading arm manipulation training device, the device comprising:

a frame having a training space therein;

at least one screen which is provided on the frame and onto which an unloading arm training video is projected;

at least one image output unit which outputs the unloading arm training video onto the at least one screen;

a trainee manipulation unit to receive one or more manipulation inputs for unloading arm manipulation by the trainee; and

a control unit to update the unloading arm training video output by the image output units according to the manipulation inputs,

wherein the at least one image output unit is provided outside the frame and output the unloading arm training video onto outer surfaces of the at least one screen to prevent a trainee positioned inside the frame from being projected onto the at least one screen,

wherein the trainee manipulation unit includes:

a movable manipulation unit used inside the frame by the trainee; and

a fixed manipulation unit used outside the frame by the trainee,

wherein only some of the manipulation inputs by the fixed manipulation unit are input to the movable manipulation unit.

2 . The device of claim 1 , wherein each of the at least one image output unit includes:

a projector which projects the unloading arm training video upward or downward; and

a reflection unit which is provided above or below the projector and reflects the unloading arm training video projected by the projector onto the screen.

3 . The device of claim 2 , wherein the projector is provided as a plurality of projectors which project unloading arm training videos of different viewpoints to provide a three-dimensional video to the trainee wearing polarized glasses.

4 . The device of claim 1 , wherein each of the at least one screen is formed of a translucent material such that the unloading arm training video projected onto the outer surface of the screen is projected inside the frame.

5 . The device of claim 1 , wherein:

when the fixed manipulation unit transmits the manipulation inputs to the control unit, the control unit updates the unloading arm training video of which a viewpoint is fixed; and

when the movable manipulation unit transmits the manipulation inputs to the control unit, the control unit updates the unloading arm training video of which a viewpoint is changed due to a position and a viewing angle of the trainee.

6 . The device of claim 1 , further comprising a detection sensor to detect a change in position of the trainee inside the frame,

wherein the control unit updates the unloading arm training video on the basis of the change in position transmitted from the detection sensor to the control unit.

7 . The device of claim 1 , further comprising a manipulation unit for administrator which receives an administration input related to at least one of a plurality of pieces of emergency situation information including a change in surrounding environment, power loss, component failure, and line disconnection between quick release hooks (QRH) and a vessel by an administrator,

wherein the control unit updates the unloading arm training video according to the administration input from the manipulation unit.

8 . The device of claim 7 , wherein at least some of the manipulation inputs by the trainee manipulation unit are restricted by the control unit according to the administration input.
