Description

[Technical Field]

[0001] The present invention relates to a training device for operating a cargo handling arm. [Background technology]

[0002] Generally, LNG (Liquefied Natural Gas) is transported by LNG carriers and transferred to onshore LNG storage tanks via unloading arms and offshore piping. In this case, the operator of the unloading arm is required to perform precise operations to connect the unloading arm to the LNG / NG connecting piping located on the LNG carrier, and if the operation is not performed correctly, there is a risk of material or personal damage occurring due to a collision between the unloading arm and the LNG carrier.

[0003] This requires skilled operators to operate the loading arms, but the problem is that it is difficult for operators to practice operating the loading arms because the arrival and departure times of LNG carriers are fluid and the number of loading arms is limited.In particular, there is a possibility that unexpected emergency situations may occur when operating the loading arms, and untrained operators may not be able to operate them properly, which could lead to accidents. Summary of the Invention [Problem to be solved by the invention]

[0004] SUMMARY OF THE INVENTION An object of the present invention is to provide a training device for operating a cargo handling arm that solves the above-mentioned problems.

[0005] The technical problems of the present invention are not limited to the above-mentioned technical problems, and other technical problems not mentioned will be clearly understood by those skilled in the art from the following description. [Means for solving the problem]

[0007] In addition, each of the video output units may include a projector that projects the loading and unloading arm training video upward or downward, and a reflector that is provided above or below the projector and reflects the loading and unloading arm training video projected from the projector onto the screen.

[0008] The projector may be a plurality of projectors each projecting a different viewpoint of the loading arm training image, and may provide a trainee wearing polarized glasses with a three-dimensional image.

[0009] In addition, the screen may be made of a translucent material so that the loading arm training image projected on the outer surface of the screen can be seen through the inside of the frame.

[0010] The training system may further include a trainee operation unit that receives at least one operation input for operating the loading arm from the trainee, and a control unit that updates the loading arm training video output by the video output unit in accordance with the operation input.

[0011] In addition, the trainee operation unit includes a mobile operation unit used by the trainee inside the frame and a fixed operation unit used by the trainee outside the frame, but only a portion of the operation input by the fixed operation unit can be input to the mobile operation unit by the control unit.

[0012] Furthermore, when the fixed operation unit transmits the operation input to the control unit, the control unit updates the loading arm training video with a fixed viewpoint, and when the mobile operation unit transmits the operation input to the control unit, the control unit can update the loading arm training video with a viewpoint that changes depending on the trainee's position.

[0013] The training device may further include a sensor for detecting a change in the position of the trainee within the frame, and the control unit may update the loading arm training video based on the change in position received from the sensor.

[0014] The system further includes an administrator operation unit that transmits to the control unit an administrative input regarding at least one of a plurality of emergency situation information items including changes in the surrounding environment, loss of power, component failure, and line separation between QRH (Quick Release Hooks) and the ship, and the control unit can update the loading arm training video in accordance with the administrative input.

[0015] Furthermore, at least a part of the operation input by the trainee operation unit can be restricted in accordance with the management input. [Effects of the Invention]

[0016] According to the present invention, a trainee can repeatedly practice operating the loading and unloading arm through the trainee operation unit.

[0017] Furthermore, according to the present invention, the trainee's ability to deal with an emergency situation can be strengthened through the manager's operation unit, and damage to equipment due to operational errors during actual operation can be prevented.

[0018] Furthermore, according to the present invention, the image output unit outputs the loading arm training image toward the outer surface of the screen, thereby preventing the trainee positioned within the frame from being projected onto the screen.

[0019] Furthermore, according to the present invention, a plurality of projectors project different cargo handling arm training images onto each screen, thereby providing trainees with a cargo handling arm training site with enhanced stereoscopic effect and realism.

[0020] In addition, according to the present invention, the reflecting unit changes the projection path and distance of the loading and unloading arm training image projected from the projector, so that the loading and unloading arm training image can be enlarged and output onto the screen even if the distance from the screen to the image output unit is not long, thereby improving space efficiency.

[0021] Furthermore, according to the present invention, the load handling arm training image can be updated according to the trainee's position and visual changes received from the sensing sensor, thereby providing the trainee with a sense of reality.

[0029] FIG. 1 is a block diagram of a cargo handling arm operation training apparatus according to an embodiment of the present invention.

[0030] Referring to FIG. 1, the loading arm operation training device 1000 may include a frame 100, a screen 200, a video output unit 300, an audio output unit 400, a trainee operation unit 500, an administrator operation unit 600, a sensing sensor 700, and a control unit 800.

[0031] The frame 100 can form a training space inside so that trainees can practice operating the load-handling arm.

[0032] The screen 200 is provided on at least one surface of the frame 100, and a loading arm training video can be projected onto it. Trainees can practice connecting and disconnecting the loading arm to and from the LNG carrier through the loading arm training video projected onto the screen 200. The screen 200 can be of various types, such as a manual screen, a motorized screen, or a fixed screen, but is not limited thereto. Alternatively, a display panel made of an LCD, an OLED, an LED, or the like can be used.

[0033] The video output unit 300 can output a loading arm training video to the screen 200. For example, the loading arm training video may include a loading arm including a plurality of outboard arms and inboard arms, a loading arm driving device and control device, an LNG carrier located at sea, an LNG storage tank on the LNG carrier, an LNG storage tank located on land, and the like.

[0034] The sound output unit 400 can output at least one sound related to the cargo handling arm training to the trainee. For example, the sound output unit 400 can output sounds generated by driving the cargo handling arm, the cargo handling arm driving device, the control device, etc., or sounds generated in response to changes in the marine environment, such as rain, wind, and waves. However, the sound output unit 400 is not limited to these.

[0035] The trainee operation unit 500 can transmit at least one operation input for operating the cargo handling arms from the trainee to the control unit 800. The operation input can include outboard arm selection / extension, outboard arm selection / folding, inboard arm selection / raising, inboard arm selection / lowering, etc. The trainee operation unit 500 can use various input devices applicable in the relevant technical field, such as keys, touch panels, switches, etc.

[0036] In the embodiment, trainee operation unit 500 transmits operation inputs for operating the loading and unloading arms from the trainee to control unit 800, and may include a mobile operation unit 510 used by the trainee inside frame 100 and a fixed operation unit 520 used by the trainee outside frame 100. In this case, only a portion of the operation inputs from fixed operation unit 520 may be input to mobile operation unit 510. For example, fixed operation unit 520 may include functions such as image switching, menu selection, device selection, and operation of audio output unit 400 in addition to the input function for operating the loading and unloading arms.

[0037] In an embodiment, when the mobile operation unit 510 transmits an operation input to the control unit 800, the control unit 800 can update the cargo handling arm training video, the viewpoint of which changes depending on the trainee's position. For example, the mobile operation unit 510 may be equipped with a position sensor, and the cargo handling arm training video can be updated based on changes in the trainee's position detected by the position sensor. Furthermore, when the fixed operation unit 520 receives an operation input, the control unit 800 can update the cargo handling arm training video with a fixed viewpoint. In this case, the fixed viewpoint may be the viewpoint where the trainee was last located immediately before operating the fixed operation unit 520. That is, when the mobile operation unit 510 transmits an operation input to the control unit 800 by the trainee, the control unit 800 can update the cargo handling arm training video projected on the screen 200 in accordance with changes in the trainee's position. Furthermore, when the fixed operation unit 520 transmits an operation input to the control unit 800 from the trainee, the control unit 800 can update the cargo handling arm training video, which is viewed from the same viewpoint regardless of changes in the trainee's position.

[0038] In an embodiment, the fixed operation unit 520 can change the mode of cargo handling arm operation training. For example, it is possible to select a training method using the mobile operation unit 510 or a training method using the fixed operation unit 520 through various input devices of the fixed operation unit 520. This allows the trainee to perform cargo handling arm operation training that is suited to the trainee operation unit 500 being used, thereby further improving the efficiency of the cargo handling arm operation training.

[0039] The administrator operation unit 600 can transmit a management input related to at least one of the multiple pieces of emergency situation information from the administrator to the control unit 800. For example, the management input can be generated by the administrator turning on or off a switch that can generate each piece of emergency situation information. In this case, the emergency situation information can include changes in the surrounding environment (e.g., changes in the marine environment such as wind direction, wind speed, water level, time, and weather), loss of power, component failure, and line separation between the QRH (Quick Release Hook) and the vessel. The administrator operation unit 600 can also use various input devices applicable in the relevant technical field, such as keys, touch panels, and switches.

[0040] In an embodiment, the administrator operation unit 600 may include at least one function of managing a trainee's training history, managing training videos, and managing evaluation reports for quantitative / qualitative evaluation. For example, a trainee's training history may include information on the trainee's training interruption or completion by task or stage. Furthermore, for example, training video management may include management of video storage, playback, and stopping, and evaluation report management may include management of a trainee's score by task or stage, score totals, and evaluation comment input.

[0041] Based on the administrator's management input transmitted from the administrator operation unit 600 to the control unit 800, the control unit 800 can update the cargo handling arm training video output by the video output unit 300. For example, when the administrator operation unit 600 transmits management input from the administrator regarding emergency situation information regarding the release of the line between the QRH of the cargo handling arm and the ship to the control unit 800, the control unit 800 can update the cargo handling arm training video to show the line between the QRH and the ship being released. At this time, the trainee can watch the updated cargo handling arm training video and input operation inputs for dealing with the emergency situation into the trainer operation unit 500. This can strengthen the trainee's ability to deal with not only given situations but also emergency situations, and prevent equipment damage due to operational errors during actual operation.

[0042] In an embodiment, in response to an administrator's management input transmitted from the administrator operation unit 600 to the control unit 800, at least a portion of the operation inputs made by the trainee operation unit 500 can be restricted by the control unit 800, particularly by control logic preset in the control unit 800. For example, when the administrator operation unit 600 transmits to the control unit 800 a management input relating to emergency situation information regarding a malfunction of one of the multiple arms of the loading arm, the trainee operation unit 500 can be restricted by the control logic preset in the control unit 800 so that the operation input related to the operation of the malfunctioning arm is not valid. In this case, the trainee can input a different operation input to the trainee operation unit 500 in place of the restricted operation input in order to deal with the emergency situation.

[0043] The detection sensor 700 can detect changes in the trainee's position and / or vision. The control unit 800 can receive a signal corresponding to the position change from the detection sensor 700 and update the loading arm training video output from the video output unit 300 based on the position change. For example, the detection sensor 700 can be a position sensor or a camera, and can be attached to the trainee's polarized glasses, work clothes, shoes, etc. to detect position changes including the trainee's speed, momentary movement changes, etc. However, the present invention is not limited thereto, and various detection technologies can be applied to the detection sensor 700 depending on the embodiment to which the present invention is applied.

[0044] In an embodiment, the detection sensor 700 may be configured with a plurality of detection sensors 700 taking into consideration the size of the frame 100, the movement of the trainee's position, the trainee's visual field, the detection angle, distance, accuracy, etc. of the trainee. The control unit 800 may update the load handling arm training video output from the video output unit 300 based on the position change received from the detection sensor 700. For example, when the trainee moves toward the screen 200 on which the load handling arm training video is projected, the control unit 800 may update the load handling arm training video so that the size of the load handling arm increases. This may provide the trainee with the same sense of reality as operating a load handling arm on an actual site.

[0045] The control unit 800 controls the overall hardware or software operation of the cargo handling arm operation training apparatus 1000. For example, the control unit 800 can update the cargo handling arm training video via the video output unit 300 or the audio output unit 400 in response to a trainee's operation input transmitted from the trainee operation unit 500 to the control unit 800 or an administrator's management input transmitted from the administrator operation unit 600 to the control unit 800, and can control the cargo handling arm operation training apparatus 1000 as a whole.

[0046] In an embodiment, the control unit 800 can control the actual operation or non-operation of not only the loading arm but also the auxiliary devices. For example, the control unit 800 includes operation or non-operation conditions (e.g., control logic) and can control the loading arm not to operate if an operation input that does not match the operation conditions is issued. Furthermore, for example, the control unit 800 can include an emergency shutdown (ESD) function and can control equipment such as the loading arm to switch to a dangerous state and not operate due to an incorrect operation or malfunction.

[0047] Although not shown in FIG. 1 , according to an embodiment, the loading arm operation training device 1000 may further include a communication unit. The communication unit is provided for direct connection to the inside and / or outside or connection via a network, and may be a wired and / or wireless communication unit. Specifically, the communication unit may transmit data from the trainee operation unit 500, the administrator operation unit 600, the detection sensor 700, the control unit 800, etc. via a wired or wireless connection, or may receive data from the outside via a wired or wireless connection and transmit it to the control unit 800 or store it in a memory. For example, the communication unit may include, but is not limited to, a short-range communication unit (Ethernet®), a Bluetooth® communication unit, a Bluetooth Low Energy (BLE) communication unit, a near field communication unit, a Wi-Fi (WLAN) communication unit, a ZigBee® communication unit, an Infrared Data Association (IrDA) communication unit, a Wi-Fi Direct (WFD) communication unit, an Ultra Wideband (UWB) communication unit, etc. The communication unit may be embodied as at least one module or chip.

[0048] 1, according to an embodiment, the cargo handling arm operation training apparatus 1000 may further include a memory. The memory can store programs for executing operations of the cargo handling arm operation training apparatus 1000, data resulting from the execution of the operations, etc. For example, the memory can include at least one type of storage medium among flash memory type, hard disk type, multimedia card micro type, card-type memory (e.g., SD or XD memory), random access memory (RAM), static random access memory (SRAM), read-only memory (ROM), electrically erasable programmable read-only memory (EEPROM), programmable read-only memory (PROM), magnetic memory, magnetic disk, and optical disk.

[0049] Not all of the components shown in Fig. 1 are essential components for the cargo handling arm operation training apparatus 1000. For example, the cargo handling arm operation training apparatus 1000 can be realized with more components than those shown in Fig. 1, or the cargo handling arm operation training apparatus 1000 can be realized with fewer components than those shown in Fig. 1.

[0050] FIG. 2 is a perspective view of a cargo handling arm operation training apparatus according to an embodiment of the present invention.

[0051] 2, the frame 100 has a screen 200 on one side, forming a training space inside, where trainees can practice operating the loading and unloading arm within the frame 100. The frame 100 may be configured in a shape such as a hexahedron, a rectangular parallelepiped, or a U-shape, but is not limited thereto.

[0052] A screen 200 is provided on at least one surface of the frame 100, onto which a loading arm training video can be projected. In an embodiment, the screen 200 is made of a translucent material, so that the loading arm training video projected on the outer surface of the screen 200 can be seen from inside the frame 100. This allows a trainee to perform loading arm operation training even inside the frame 100. The screen 200 may be made of any one selected from the group consisting of, but not limited to, PET (Polyethyleneterephtalate), PVC (Polyvinyl Chloride), PC (Polycarbonate), glass, and acrylic, and any material that is translucent enough to allow the loading arm training video to be seen from inside the frame 100 can be used for the screen 200.

[0053] In the embodiment, the screen 200 may be provided on only one side of the frame 100, but is not limited thereto, and a plurality of screens 200 may be provided on three or six sides of the frame 100. For example, a first screen 210 may be provided in front of a trainee positioned inside the frame 100, a second screen 220 may be provided on the left side, and a third screen 230 may be provided on the right side.

[0054] 2 shows the loading arm training video being projected only onto the first screen 210, but according to an embodiment, the entire loading arm training video can be separately projected continuously and three-dimensionally onto the first screen 210, the second screen 220, and the third screen 230. That is, the entire loading arm training video is separately projected onto the three screens 200, and thus the loading arm training video is projected continuously and three-dimensionally onto the three sides of the frame 100, which can improve the trainee's sense of immersion and realism in the loading arm operation training.

[0055] In addition, for example, the control unit 800 may update the loading arm training video on the first screen 210 in response to the trainee's operation input transmitted from the trainee operation unit 500 to the control unit 800, and an image that allows the trainee to practice operating the loading arm may be projected. Specifically, for example, an image showing the most appropriate method of operating the loading arm may be projected on the second screen 220, allowing the trainee to determine whether their operation input was appropriate and confirm the most appropriate operation method. As another example, a control logic flowchart or operation guide may be projected on the second screen 220 so that the trainee's operation input can be determined to be a valid operation or an incorrect operation according to a preset control logic. However, the present invention is not limited to this.

[0056] Furthermore, for example, loading and unloading arm operation training images showing different situations may be projected onto the first screen 210, the second screen 220, and the third screen 230, respectively. For example, the control unit 800 may update the loading and unloading arm operation training image on the screen the trainee is looking at in response to the trainee's operation input, based on a change in the trainee's vision transmitted from the detection sensor 700 to the control unit 800. As another example, loading and unloading arm operation training images from the visual angle of a third party (e.g., a training observer) may be projected onto the second screen 220 and the third screen 230, allowing not only the trainee but also the training observer to indirectly perform loading and unloading arm operation training. However, this is not limited to this.

[0057] At least one video output unit 300 is provided corresponding to the screen 200, and can output a loading arm training video toward the screen 200. In an embodiment, the video output unit 300 is provided outside the frame 100, and can output a loading arm training video toward the outer surface of the screen 200. This prevents a trainee positioned inside the frame 100 from being projected onto the screen, and allows the trainee to clearly view the loading arm training video even when the training location inside the frame 100 is bright.

[0058] In an embodiment, when the screen 200 is configured with a plurality of screens 200, the image output unit 300 may also be configured with a plurality of image output units 300 corresponding to each screen 200. In this case, each image output unit 300 may project a different loading arm training image corresponding to each screen 200.

[0059] The cargo handling arm operation training device 1000 shown in FIG. 2 is an example, and various configurations can be applied depending on the embodiment to which the present invention is applied.

[0060] FIG. 3 is a diagram illustrating a video output unit according to an embodiment of the present invention.

[0061] 3, the image output unit 300 may include a projector 310 that projects a cargo handling arm training image upward or downward. In an embodiment, the projector 310 may include a plurality of projectors 310, each projecting a cargo handling arm training image from a different perspective. This may provide a trainee wearing polarized glasses with a three-dimensional image, thereby providing the trainee with a cargo handling arm training site with a higher sense of three-dimensionality and realism.

[0062] The image output unit 300 may include a reflector 320 provided above or below the projector 310. The reflector 320 may reflect the cargo handling arm training image projected from the projector 310 onto the screen 200. By changing the projection path of the cargo handling arm training image, the cargo handling arm training image can be enlarged and output on the screen 200 even if the distance from the screen 200 to the image output unit 300 is not long, thereby improving space efficiency.

[0063] The video output unit 300 shown in FIG. 3 is merely an example, and various configurations may be applied depending on the embodiment to which the present invention is applied.

[0064] FIG. 4 shows an example of use of the cargo handling arm operation training device according to the embodiment of the present invention.

[0065] 4(a) shows an example of use in which the mobile operating unit 510 transmits operation input from the trainee to the control unit 800. When the mobile operating unit 510 transmits the trainee's operation input to the control unit 800, the control unit 800 can update the cargo handling arm training video projected from the video output unit 300 so that the viewpoint changes depending on the trainee's position. In this case, the detection sensor 700 provided on one side of the frame 100 detects a change in the trainee's position, and the control unit 800 can update the cargo handling arm training video based on the change in position.

[0066] 4(b) shows an example of use in which the fixed operation unit 520 transmits an operation input from the trainee to the control unit 800. When the fixed operation unit 520 transmits the operation input to the control unit 800, the control unit 800 can update the loading arm training video with a fixed viewpoint. In this case, the fixed reference viewpoint can be the viewpoint where the trainee was last located immediately before operating the fixed operation unit 520.

[0067] At this time, the fixed operation unit 520 can change the mode of the cargo handling arm operation training to select a training method using the mobile operation unit 510 or a training method using the fixed operation unit 520. This allows the trainee to perform cargo handling arm operation training that is suited to the trainee operation unit 500 being used, thereby further improving the efficiency of the cargo handling arm operation training.

[0068] FIG. 5 shows an example of use of the cargo handling arm operation training device according to the embodiment of the present invention.

[0069] 5(a) shows an example of use of the load handling arm operation training device relating to the outboard arm of a load handling arm. When the trainee's operation unit 500 transmits an operation input from the trainee to the control unit 800 to extend or fold the outboard arm, the control unit 800 can update the load handling arm training video so that the outboard arm of the load handling arm is extended or folded. In general, the operation input to extend the outboard arm can be updated with the load handling arm moving forward and upward, and the operation input to fold the outboard arm can be updated with the load handling arm moving backward and downward.

[0070] 5(b) shows an example of use of the cargo handling arm operation training device relating to the inboard arm of the cargo handling arm. When the trainee's operation unit 500 transmits an inboard arm raising or inboard arm lowering operation input from the trainee to the control unit 800, the control unit 800 can update the cargo handling arm training video so that the inboard arm of the cargo handling arm rises or falls. In general, the inboard arm raising operation input can be updated with the cargo handling arm moving backward and rising, and the inboard arm lowering operation input can be updated with the cargo handling arm moving forward and falling.

[0071] As described above, the drawings and specification disclose the best mode for carrying out the present invention. Although specific terms are used herein, they are used merely for the purpose of describing the present invention, and are not used to limit the meaning or the scope of the present invention as described in the claims.
