The display group, touch screen 5, control handle, function buttons, and emergency stop switch group are placed on the desktop of the control console body. The loading control computer 14, the video monitoring computer 13, the control console switch 15, and the control console electrical cabinet 16 are placed on the control console body. The control console switch 15 is communicatively connected to multiple bulk cargo loaders. The control console electrical cabinet 16 is connected to the touch screen 5, the control handle, the function buttons, the emergency stop switch group, and the control console switch 15. The loading control computer 14 is connected to the control console switch 15. The video monitoring computer 13 is connected to the display group and the control console switch 15. The emergency stop switch group includes emergency stop switches (17, 18, 19, 20) corresponding to the bulk cargo loaders, used to power off and stop the corresponding bulk cargo loaders.

[0024] In this embodiment, the control device is installed in the automated remote control room of the ship loader. The control table is equipped with displays (1, 2, 3, 4), touch screen 5, control handles (6, 7), function buttons (8, 9, 10, 11, 12) and emergency stop switches (17, 18, 19, 20). Under the control table are the ship loading control computer 14, video monitoring computer 13, control console switch 15 and control console electrical cabinet 16.

[0025] The aforementioned video monitoring computer 13 is used to collect and display video footage from the bulk cargo loader.

[0026] The aforementioned ship loading control computer 14 is used to run remote ship loading software that controls the bulk cargo loader.

[0027] The aforementioned console switch 15 is used to manage all control and video signal interactions between the console equipment and the ship loader.

[0028] The aforementioned control console electrical cabinet 16 is used to collect, process, and output all signals from the tabletop devices (5, 6, 7, 8, 9, 10, 11, 12, 17, 18, 19, 20).

[0029] The emergency stop switches (17, 18, 19, 20) mentioned above correspond to bulk material loader machines and are used to immediately cut off the control power supply of the corresponding loader machine in an emergency.

[0030] Furthermore, the function buttons include a machine number switching knob 8, used to select the machine number of the bulk material loader to be controlled. The machine number switching knob 8 is used to manually switch the bulk material loader machine number bound to the control software, and is linked to the touch screen 5, the control handle, and the function buttons to control the switched bulk material loader.

[0031] In this embodiment, the machine number switching knob 8 is used to manually switch the machine number of the ship loader bound to the control software, and simultaneously switch the control objects of the touch screen, control handle and function buttons.

[0032] Furthermore, the function button includes a remote manual / automatic switching knob 9, used to switch the currently bound bulk cargo loader between remote manual mode and remote automatic mode.

[0033] Furthermore, the function buttons include a power-on button 11 and a power-off button 12, used to engage or disengage the power supply to the currently bound bulk loader.

[0034] It should be noted that the button signal can be switched by software to correspond to different machine numbers, while the emergency stop switch only achieves one-to-one power cut-off and does not change with the software.

[0035] Furthermore, the function buttons include a fault reset button 10, which is used to clear the fault status of the currently bound bulk cargo loader.

[0036] Furthermore, the display group includes multiple video monitoring displays (1, 2, 3) and a ship loading control software display 4; the video monitoring displays (1, 2, 3) are used to display the video monitoring screen of the bound ship loading machine in real time; the ship loading control software display 4 is used to display the automatic ship loading control software screen of the bound ship loading machine.

[0037] In this embodiment, displays (1, 2, 3) are used to view the video monitoring screen of the controlled ship loader, and the screen updates automatically as the machine number bound to the control console changes. Display 4 is used to switch the remote manual / automatic loading mode of the controlled ship loader, and its display screen also updates automatically as the bound machine number changes. When the control console is in one-to-one control mode, displays (1, 2, 3) display the video monitoring screen of the bound ship loader, and display 4 displays the automatic loading control software screen of that ship loader. When the control console is in one-to-many control mode, displays (1, 2) display the video monitoring screen of the first ship loader, display 3 displays the video monitoring screen of the second ship loader, and display 4 displays the automatic loading control software screen of the currently selected machine number. The bound machine number is switched by the machine number switching knob 8 or by software.

[0038] Furthermore, the control handle includes a pitch and slew control handle 6 and a travel and trolley lifting control handle 7; the pitch and slew control handle 6 is used to control the bound ship loader to complete the cantilever slew and cantilever pitch; the travel and trolley lifting control handle 7 is used to control the bound ship loader to complete the trolley lifting and the trolley travel.

[0039] In this embodiment, the pitch and slew control handle 6 is a dual-axis joystick: the left and right axes control the cantilever rotation, and the front and rear axes control the pitch; the travel and sled lifting control handle 7 also adopts a dual-axis joystick, with the left and right axes driving the trolley to travel and the front and rear axes driving the sled lifting.

[0040] Furthermore, the touchscreen 5 is used to control the components and equipment on the bound ship loader and to display their status.

[0041] In this embodiment, the chute rotation, pitch angle, travel speed, and belt start / stop are controlled individually via virtual buttons, while the attitude of each mechanism, motor current, material level height, and fault codes are displayed in real time.

[0042] The control console software includes conventional electronic control system software and automated loading control software.

[0043] The electrical control system software runs in the PLC of the control console electrical cabinet 16. Its main functions include controlling the power supply in remote manual mode, fault reset, machine number binding switching, manual / automatic switching, etc., and processing equipment data such as touch screen, control handle, emergency stop switch, etc.

[0044] The electrical control system software is the core of the system, enabling a single console to control multiple ship loaders simultaneously. The specific logic is as follows: Operation begins with selecting a specific ship loader, such as loader ① or loader ②, and then closing the control power supply. The operator then selects either manual or automatic mode to control the ship loader. In automatic mode, the necessary parameters are set through the automatic loading software, and the ship loader enters automatic loading mode. Operational parameters can be fine-tuned through both software and manual hardware adjustments. In manual mode, the operator issues commands through the manual loading components to control the ship loader's actions. Throughout the process, the system monitors the emergency stop switch signal in real time. Once triggered, it immediately sends a signal to disconnect the control power supply to ensure safety. Upon completion of the operation or in an emergency, the control power supply is disconnected, ending the operation of the current ship loader. This process can be repeated for other ship loaders, enabling effective management of multiple ship loaders from a single console.

[0045] The automatic loading software runs on the loading control computer 14 in the control console. Its main functions include parameter setting, cabin scanning, path planning, loading control, and status display in the remote automatic loading mode. The automatic loading software runs in the background of the computer and simultaneously binds to and controls four loading machines. It is the software component that enables automatic loading by a single loading machine; it can only achieve the goal of controlling multiple loading machines to complete automatic loading from a single control console when used in conjunction with the electrical control system program. The control console uses a strategy of sequentially binding machine numbers and activating remote automatic control for multiple controlled loading machines (such as loading machine ① and loading machine ②), enabling simultaneous control of one or more loading machines for automatic loading operations.

[0046] During the ship loading preparation phase, when the control console number selection button selects ship loader ①, pressing the control power close button will connect the control power supply to ship loader ①. The ship loader is in manual control mode by default, and the operator adjusts the operating parameters of ship loader ① through the manual control component. Switching the automatic / manual switch to automatic mode allows setting the operating parameters through the automatic ship loading software and putting ship loader ① into automatic loading mode. When ship loader ① is in automatic loading mode, its operating parameters can be adjusted through the automatic ship loading software and the manual control component.

[0047] By repeating the above steps, ship loader ② and other ship loaders of different sizes can be put into automatic loading mode in sequence.

[0048] During the loading supervision phase, the automatic loading software on the control panel will select the position of the button according to the machine number, bind the machine number of the loading machine that is put into automatic loading mode, and display the signal parameter status of the loading machine. At this time, both the automatic loading software and the manual control component are bound to the loading machine with that machine number.

[0049] In summary, this utility model, through the integrated design of hardware and conventional software, enables the same control console to switch machine numbers at any time, thereby allowing multiple bulk material loaders to perform remote manual or remote automatic loading operations, reducing the number of control consoles and saving manpower. Through the coordination of the electrical control system and the machine number switching knob, the same control console can sequentially bind and simultaneously control one, two, or more bulk material loaders for remote automatic loading, improving berth operation efficiency. Using the remote manual / automatic switching knob, operators can instantly switch the operating mode of the bound loaders on the control console without going to the machine, enhancing operational flexibility. Utilizing the slewing / pitch control handle and the travel / drum lifting control handle, the control console can adjust the loader's motion parameters in real time in both remote manual and remote automatic modes, achieving centralized control. Through the combination of a display, touchscreen, and various function buttons, operators can simultaneously monitor the loader's status information and video feed on the control console and issue adjustment commands instantly, improving monitoring intuitiveness. Four emergency stop switches correspond to different machine numbers; triggering any button immediately cuts off the corresponding loader's control power, achieving emergency power outage and shutdown, ensuring production safety. The video control computer is linked to the machine number switching knob, so that the video screen on the monitor automatically switches according to the machine number bound to the software, avoiding manual selection and improving the operation response speed.

[0050] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
