[0058] (4) Reduced training costs and risks: By using virtual simulation for operator training, the costs and potential risks of using real equipment can be significantly reduced. The simulation system allows crane operators to learn and make mistakes in an environment without the risks of physical machinery, which is key to improving the safety and effectiveness of training.

The operation signal processing module is connected to the operation signal acquisition module and the virtual simulation calculation module via a PLC device, while the virtual simulation calculation module is connected to the virtual simulation presentation module. A detailed description of each component is provided below.

[0071] The operation signal acquisition module is used to collect remote operation signals of the virtual shore container crane. The operation signal acquisition module includes the console master handle, console control buttons and HMI touch screen. The following describes each part:

[0072] The main control handle of the operating console is connected to the digital input point of the PLC device through a wire, and is used to send speed control signals of the crane trolley travel, car travel, and spreader lifting and lowering, as well as CCTV camera rotation and zoom control signals to the PLC device.

[0073] Specifically, three master control handles are designed, each with an integrated independent button to achieve functional expansion. Among them:

[0074] The left-hand main control handle is a four-way handle used to control the front, back, left, and right tilt of the spreader, as well as the up, down, left, and right rotation of the CCTV camera. Two independent buttons 1 and 2 on the handle can switch between two control modes, thus achieving functional reuse of the handle.

[0075] The center main control handle is a two-way handle used to control the forward and backward movement of the trolley. It integrates four independent buttons: buttons 3 and 4 activate and deactivate the spreader's anti-sway and anti-twist functions, while buttons 5 and 6 control the extension and retraction of the spreader's center lock, enabling the spreader to simultaneously lift two 20-foot containers.

[0076] The right-hand main control handle is a four-way handle used to control the left and right movement of the trolley and the lifting and lowering of the spreader. It also integrates four independent buttons. Independent buttons 7 and 8 control the opening and closing of the spreader's rotary lock, locking the spreader to the container. Independent buttons 9 and 10 control the rotation of the spreader's guide plate, guiding the spreader to the container during loading and unloading.

[0077] The control buttons on the operating console are connected to the I / O input points of the PLC device through wires and are used to send crane control on / off, fault bypass, fault reset, remote manual / auto switching, and emergency stop signals to the PLC device.

[0078] The HMI touch screen is connected to the PLC device via a POE switch and is used to simulate operation task instructions, CCTV camera selection instructions, and operation ship diagram display.

[0079] The operation signal processing module is used to receive the master handle signal, control button signal, and HMI touch screen signal from the operation signal acquisition module, process the operation signal, and send the control signal to the virtual simulation calculation module according to the control logic to control the virtual shore container crane to perform the corresponding action. The operation signal processing module includes a PLC device and a POE switch. The components are described as follows:

Specifically, the PLC device adopts a modular structure, including a power module, a CPU module, a digital I / O module, and a network communication module. The PLC device uses a Siemens S7-1200 series CPU and communicates with the OPC UA server using the Modbus communication protocol.

[0081] The POE switch is used to send the obtained operation execution control signal to the virtual simulation computing module through the POE switch.

[0082] The virtual simulation calculation module is used to simulate the dynamics of the crane's trolley, trolley, wire rope, spreader, and container, as well as the physical characteristics of collision, friction, and swing, and to calculate the crane's status, faults, and alarm information. It also renders a three-dimensional virtual scene of the virtual shore container crane and its operating environment. It also monitors equipment status information, equipment operation task information, container truck arrival status, and equipment operation switching reminders, and renders a two-dimensional monitoring screen. By adjusting the spreader's amplitude, it can simulate the spreader's swing effects in both conventional and anti-sway operation modes. The virtual simulation calculation module includes a computer host and an OPC UA server. Each component is described below:

[0083] The computer host includes a virtual crane operation simulation unit and a virtual remote crane monitoring simulation unit. The virtual crane operation simulation unit is used to simulate the dynamics of the crane trolley, car, wire rope, spreader, and container, as well as the physical characteristics of collision, friction, and swing, and calculate the crane's status, faults, and alarm information. Simultaneously, it renders a three-dimensional virtual scene of the virtual shore container crane and its operating environment. The virtual remote crane monitoring simulation unit receives simulation calculation results from the virtual crane operation simulation unit and is used to monitor equipment status information, equipment operation task information, container truck arrival status, and equipment operation switching reminders, and renders a two-dimensional monitoring screen. The three-dimensional scene screen of the virtual crane operation simulation unit and the two-dimensional monitoring screen of the virtual remote crane monitoring simulation unit are superimposed and displayed in a block layout on a combined screen.

[0084] Among them, the virtual simulation calculation unit can simulate the swing effect of the spreader in the conventional operation mode and the anti-sway operation mode by setting the amplitude of the spreader. According to the motor driving force F of the three major mechanisms of the virtual shore container crane trolley, trolley and spreader, the virtual simulation calculation unit can simulate the swing effect of the spreader in the conventional operation mode and the anti-sway operation mode. g 、F r 、F s , motor starting time t g , t r , t s , mass m g 、m r 、m s , acceleration a g 、a r 、a s , initial velocity u g 、u r 、u s , maximum speed GV max RV max SV max And gravitational acceleration g, wire rope length L, container mass m cAnd the following parameters, calculate the real-time velocity components of different crane mechanisms in three-dimensional space coordinates.

[0106] The OPC UA server interacts with the PLC devices through integrated PLC communication drivers from different manufacturers, and interacts with the computer host through the OPC UA standard communication protocol.

[0107] The virtual simulation presentation module is used to render a three-dimensional virtual scene of the virtual quayside container crane and its operating environment, display it on a split screen, and monitor the operating information of the virtual quayside container crane.
