Description

Technical Field

[0001] This invention relates to the field of technical training equipment, specifically to a gantry crane model training device and method based on an electronically controlled simulation panel. Background Technology

[0002] In dock operations, how to efficiently and cost-effectively improve the practical operation and troubleshooting capabilities of technical personnel has always been a focus of industry attention. Traditional training methods often lack effective practical operation means, making it difficult for technical personnel to quickly and accurately deal with various equipment problems in actual work.

[0003] To address this, invention patent CN106781928B discloses a virtual-real combined crane electrical control simulation system, mainly composed of physical circuits, virtual circuits, and an interactive system. The physical circuit is a dedicated circuit designed to simulate the actual mechanism, primarily responsible for reproducing the electrical actions of a specific mechanism of the simulated crane in the simulation trainer, thus enhancing the trainee's perceptual understanding. The virtual circuit mainly consists of circuits simulated via PC software, simulated instrument displays, and related electrical cabinet servers. The virtual circuit serves as a supplement to the physical circuit, reducing the cost of implementing the physical circuit, lowering the failure rate, and simulating corresponding electrical actions to provide trainees with the necessary feedback. The interactive system includes a teacher-side control system, an electrical fault setting system, a physical linkage console, and a virtual visual system. This system achieves multiple uses with a single device, reduces the cost of simulation equipment, facilitates upgrades and updates, and enhances the trainee's perceptual understanding.

[0004] The above-mentioned technical solutions have made progress in the combination of virtual and real systems and system integration, but the following technical problems still exist: the physical circuit only covers a single mechanism loop, and trainees cannot simultaneously access and operate the actual electrical components of multiple key mechanisms, which limits the accumulation of comprehensive practical experience; in addition, the system lacks direct linkage with the physical crane model, making it difficult to provide intuitive understanding of the device structure and overall operation perception, which affects the immersion of the training and the authenticity of the hands-on practice.

[0005] In view of this, the present invention provides a training device and method for a gantry crane model based on an electronically controlled simulation panel. Summary of the Invention

[0006] The purpose of this invention is to solve the problems of multiple mechanisms not being able to operate simultaneously and poor linkage with physical crane models in the prior art. In response to the technical defects of the prior art, this invention provides a training device and method for a gantry crane model based on an electronically controlled simulation panel to solve the above-mentioned technical problems.

[0007] To achieve the above objectives, the present invention provides the following technical solution: In a first aspect, the present invention provides a training device for a gantry crane model based on an electronically controlled simulation panel, comprising an electronically controlled simulation panel and a gantry crane model, the device further comprising: The electrical control simulation panel includes a touch screen, a DC power supply, a PLC controller, limit switches, control buttons, a frequency converter, and terminal blocks.

[0008] The power supply terminal of the touch screen is connected to a DC power supply, and the data terminal of the touch screen is connected to a PLC controller. The PLC controller is connected to the data terminal and control terminal of the frequency converter, and is also connected to the signal terminal of the limit switch and control button.

The gantry crane model is connected to the electrical control simulation panel, and the components of the electrical control simulation panel are connected to the gantry crane model as an integrated device through a PLC controller, frequency converter, and terminal block.

[0009] Secondly, the present invention provides a training method for a gantry crane model based on an electronically controlled simulation panel, comprising the following steps: Step S1: Start and initialize the device; the touchscreen displays device status information. Step S2: The student selects the operation mode and sets the relevant parameters via the touchscreen; Step S3: The PLC controller receives the instruction and outputs a control signal to the frequency converter to adjust the motor speed and start the gantry crane model; Step S4: Trainees operate the gantry crane model by using the control buttons to execute the set actions and observe the operating status of the device in real time. Step S5: After completing the operation, the trainee performs fault diagnosis based on the fault simulation scenario, ends the training, and resets the device.

[0010] The beneficial effects of this invention are as follows: This invention solves the technical problem of lacking simultaneous operation of multiple mechanisms in existing technologies by using a control method based on an electronically controlled simulation panel. Trainees can simultaneously operate the hoisting, slewing, and luffing mechanisms of a gantry crane on the same control platform, achieving coordinated control of multiple mechanisms. This design not only enhances the realism of the training but also strengthens trainees' understanding and mastery of the coordinated operation of various mechanisms within the device.

[0011] This invention achieves precise linkage with a gantry crane model through the interlocking of a PLC controller and a frequency converter. During operation, trainees can make real-time adjustments via a touchscreen and control buttons, accurately simulating the working environment of a gantry crane. This function greatly enhances trainees' understanding of the gantry crane's operating status and their emergency operation capabilities, making simulation training more closely aligned with actual operation.

[0012] The limit switch of this invention ensures that when the moving parts of the gantry crane reach the set limit position, it can promptly feed back a signal to the PLC controller, thereby avoiding overload operation of the mechanical parts; effectively preventing damage to the gantry crane due to improper operation or mistakes, and ensuring the long-term stable operation of the gantry crane model and the safety of trainees.

[0013] The control buttons of this invention allow trainees to operate quickly via physical buttons and receive real-time feedback through indicator lights. This design enhances ease of operation, improves trainee efficiency during training, and enables trainees to better grasp the operating status of the gantry crane and adjust their operating strategies accordingly.

[0014] This invention can simulate the actual working conditions of a gantry crane and effectively help trainees master the operating skills and troubleshooting techniques of gantry cranes. Through repeated practical training, trainees can improve their operating skills and enhance their maintenance and emergency response capabilities for gantry cranes, thereby ensuring safe production and efficient operation in actual work.

Detailed Implementation

[0018] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following implementation methods.

[0019] Example 1: like Figure 1 As shown in the figure, this embodiment provides a gantry crane model training device based on an electronically controlled simulation panel, including an electronically controlled simulation panel and a gantry crane model.

For example, inverter 6 is a Siemens MicroMaster420 inverter.

[0021] The positive and negative terminals of the DC power supply 2 are respectively connected to the power supply terminals of each component of the electronic control simulation disk; The control button 5 is installed on the front panel of the electronic control simulation panel and is connected to the PLC controller 3 via a signal line; The gantry crane model is connected to the electrical control simulation panel. The components of the electrical control simulation panel are connected to the gantry crane model as an integrated device through the PLC controller 3, frequency converter 6, and terminal block 7.

[0022] Example 2: like Figure 1 As shown in the figure, this embodiment provides a gantry crane model training device based on an electronically controlled simulation panel, including an electronically controlled simulation panel and a gantry crane model. The device also includes: The electronic control simulation panel includes a touch screen 1, a DC power supply 2, a PLC controller 3, limit switches 4, control buttons 5, a frequency converter 6, and terminal blocks 7.

[0023] The power supply terminal of the touchscreen 1 is connected to the DC power supply 2, and the data terminal of the touchscreen 1 is connected to the PLC controller 3. The touchscreen 1 is used to display the system status, the gantry crane operation interface, and control parameters, providing an interface for operator interaction with the system; the DC power supply 2 provides a stable power supply for the entire device, ensuring the normal operation of all components.

[0024] The PLC controller 3 is connected to the data terminal and control terminal of the frequency converter 6, and is also connected to the signal terminal of the limit switch 4 and the control button 5. For example, the mainstream PLC controller is Siemens PLC, including S7-200, S7-300, S7-400, S7-1200 and S7-1500.

[0025] The PLC controller 3, as the core component of the electrical control simulation panel, is used to control and detect faults in the various motion mechanisms of the gantry crane model. The frequency converter 6, through the PLC controller 3, adjusts the motor speed and operating mode to ensure the accurate operation of the hoisting, rotating, and luffing mechanisms of the gantry crane model. The limit switch 4 is used to detect the operating status of the gantry crane model, ensuring that it does not exceed safe limits during operation and preventing mechanical failures. The control button 5 is connected to the PLC controller 3, allowing the operator to manually adjust the operating status of the gantry crane model or set the training mode.

[0026] The terminal block 7 is connected to the touch screen 1, PLC controller 3, frequency converter 6, limit switch 4, control button 5 and DC power supply 2. The terminal block 7 is used to connect the various electrical components to the PLC controller 3 to ensure the stability and reliability of the circuit.

[0027] For example, inverter 6 is a Siemens MicroMaster420 inverter.

[0028] The positive and negative terminals of the DC power supply 2 are respectively connected to the power supply terminals of each component of the electronic control simulation disk; The control button 5 is installed on the front panel of the electronic control simulation panel and is connected to the PLC controller 3 via a signal line; The gantry crane model is connected to the electrical control simulation panel. The components of the electrical control simulation panel are connected to the gantry crane model as an integrated device through the PLC controller 3, frequency converter 6, and terminal block 7.

[0029] Furthermore, the limit switch 4 includes a photoelectric sensor and a mechanical limit switch. The photoelectric sensor is used to detect the movement position of the gantry crane model, ensuring that the model operates accurately during operation. The mechanical limit switch is used to ensure that the model does not exceed the preset maximum safety range, thereby preventing damage to the gantry crane or potential safety hazards.

[0030] Furthermore, the touchscreen 1 is equipped with a fault simulation module to simulate fault scenarios of the gantry crane. Technicians can use this module to practice troubleshooting. When the gantry crane malfunctions, this module is electrically connected to the PLC controller 3, displays fault information on the touchscreen 1, and guides the operator to analyze and handle the fault, thereby improving the technicians' ability to respond.

[0031] Furthermore, the gantry crane model is made at a 1:300 scale. The structure of the gantry crane model is similar to that of the actual gantry crane, including columns, gantry frame, top beam and various mechanism support components. It is controlled as a whole through an electronic control simulation panel, allowing technicians to practice operation and simulate faults in a safe environment.

[0032] Furthermore, the gantry crane model includes a hoisting mechanism, a slewing mechanism, and a luffing mechanism, which are connected to the PLC controller 3 and frequency converter 6 of the electronic control simulation panel to achieve precise control of the actions of each mechanism.

[0033] Furthermore, the hoisting mechanism, slewing mechanism, and luffing mechanism of the gantry crane model are equipped with motors and sensors, which are connected to the components of the electronic control simulation panel to form an integrated device. The PLC controller 3 controls the model's actions based on the input signals from the limit switch 4, control button 5, and touch screen 1, and the frequency converter 6 adjusts the motor's running speed, thereby achieving coordinated actions of each mechanism.

[0034] Furthermore, the various components of the electrical control simulation panel are connected to the gantry crane model through terminal block 7, DC power supply 2 and signal lines to form a closed loop. After receiving signals from touch screen 1, control button 5 and limit switch 4, PLC controller 3 adjusts frequency converter 6 to coordinate the actions of lifting, rotating and luffing mechanisms, ensuring coordinated operation between the various mechanisms of the gantry crane model.

[0035] This device allows technicians to conduct various operational training sessions on gantry cranes, familiarize themselves with their working principles and operating techniques, and enhance the effectiveness of practical training. The control precision of the gantry crane model is monitored via an electronic control simulation panel, and the operation methods are adjusted and monitored through the same panel. A touchscreen provides a real-time display of the operating status, facilitating precise control by the operator. The frequency converter, by adjusting the motor speed, simulates the frequency conversion function of the gantry crane, further enhancing the realism of the training and enabling technicians to better understand the working mechanism of the gantry crane.

[0036] Example 3: like Figure 2 As shown in the figure, this embodiment provides a training method for a gantry crane model based on an electronically controlled simulation panel, which includes the following steps: Step S1: Start and initialize the device; the touchscreen displays device status information. Step S2: The student selects the operation mode and sets the relevant parameters via the touchscreen; Step S3: The PLC controller receives the instruction and outputs a control signal to the frequency converter to adjust the motor speed and start the gantry crane model; Step S4: Trainees operate the gantry crane model by using the control buttons to execute the set actions and observe the operating status of the device in real time. Step S5: After completing the operation, the trainee performs fault diagnosis based on the fault simulation scenario, ends the training, and resets the device.

[0037] In step S1: the electrical control simulation panel initializes the gantry crane model through the PLC controller and frequency converter. The trainee turns on the power and checks the connection status and operational readiness of each component. The touch screen displays the status information of the gantry crane model in real time, such as the motor running status, the working status of the controller and frequency converter, etc., to ensure that each component is working properly. The PLC controller performs a self-test, and the touch screen displays the status information of the gantry crane model, including basic information such as the power supply, current, and voltage of the gantry crane model.

[0038] This step ensures that the gantry crane model is initialized in a safe state and provides real-time status feedback, allowing trainees to understand the operating status of the gantry crane and confirm that the preparation work for the gantry crane is correct.

[0039] The electrical control simulation panel is equipped with mainstream Siemens PLC controllers and frequency converters, and features touchscreen control. The hardware structure of the simulation panel includes high-quality electrical components and a scientifically sound and stable circuit design. The software structure utilizes professional programming software to write control programs, providing a user-friendly interface and rich functional modules. Through this simulation panel, technicians can practice practical skills required for various industry competitions in advance. Simultaneously, the simulation panel can simulate equipment actions and common equipment fault points for daily on-the-job training and troubleshooting. For example, when simulating equipment failure, the simulation panel will randomly generate fault scenarios. Technicians need to analyze the fault phenomena, identify the cause, and solve the problem, effectively improving the overall skill level of technicians.

[0040] The gantry crane model is connected to the electrical control simulation panel. Through self-developed PLC programs and debugged frequency converters, various actions of the gantry crane's hoisting, rotating, and luffing mechanisms are realized. Based on the structure and working principle of an actual gantry crane, a gantry crane model is created at a 1:300 scale. The developed PLC program and debugged frequency converter are applied to the model's control, achieving precise control of the gantry crane model. Technicians can control the model to perform hoisting, rotating, and luffing operations through the knobs and touchscreen of the electrical control simulation panel. They can also perform frequency conversion and speed change operations on the three-phase asynchronous motor through the touchscreen, and obtain the actual motor speed through the touchscreen's actual speed interface. This function simulates the frequency conversion function of the gantry crane's mechanism motors, helping maintenance personnel to better understand the working principle of the device. For example, when the various mechanisms of the gantry crane are running, technicians can observe the operation of the hoisting, rotating, and luffing mechanisms through different control methods, further deepening their understanding of the gantry crane's working principle and control methods.

[0041] In step S2, the trainee selects the desired operation mode on the touchscreen interface, such as hoisting, rotating, or luffing, and sets parameters such as motor speed, hoisting height, and rotation angle according to actual needs. During this process, the PLC controller receives the parameters input from the touchscreen and adjusts the motor speed of the gantry crane model via the frequency converter to ensure its actions match the trainee's settings. Through this step, the trainee can select and set training content and parameters according to actual needs, achieving precise control of the gantry crane model through the touchscreen, thus improving their understanding and mastery of the equipment operation.

[0042] In step S3, the PLC controller, based on the parameters input by the trainee, controls the inverter output signal to adjust the speed of the three-phase asynchronous motor, thereby controlling various actions of the hoisting, rotating, and luffing mechanisms of the gantry crane model. The electrical control simulation panel is connected to the gantry crane model, and the simulation panel controller displays the actual motor speed via a touchscreen, allowing trainees to observe the real-time operating status of each mechanism. Trainees can adjust the motor speed via the touchscreen and monitor the operating status of each mechanism of the crane model in real time. Through the actual speed interface displayed on the touchscreen, trainees can deepen their understanding of the motor control principle of the device.

[0043] In step S4, the trainee operates the device via buttons or a touchscreen on the electronic control simulation panel, controlling the gantry crane model to perform set actions, such as starting, stopping, and adjusting speed. During operation, the electronic control simulation panel simulates different fault scenarios, requiring the trainee to diagnose and troubleshoot based on the simulated fault phenomena. By personally operating the device, trainees can deepen their familiarity with the electronic control simulation panel and the gantry crane model, while simultaneously improving their fault diagnosis and troubleshooting abilities when the device simulates faults.

[0044] In step S5: After the operation, the trainee performs fault diagnosis and troubleshooting based on the fault scenarios randomly generated by the device. The trainee analyzes the causes of the faults and makes adjustments based on feedback from the simulation panel. During this process, the PLC controller resets each mechanism to its initial position, and the touchscreen displays the device's reset status, ensuring the device is in its initial state and ready for the next round of training. Through simulated fault handling, the trainee improves their fault diagnosis and device debugging capabilities; the reset operation ensures the device can be restored to a safe state before the next use, providing a reliable guarantee for subsequent training.

At the same time, they can also perform frequency conversion and speed change operations on the three-phase asynchronous motor through the touch screen, and obtain the actual speed of the motor through the actual speed interface of the touch screen. In step S2: the trainee selects the desired operation mode on the touch screen interface and sets the motor speed, lifting height, and rotation angle parameters according to actual needs; during this process, the PLC controller receives the parameters input from the touch screen and adjusts the motor speed of the gantry crane model through the frequency converter to ensure that its actions conform to the trainee's settings. In step S3: the PLC controller controls the inverter output signal according to the parameters input by the trainee, adjusts the speed of the three-phase asynchronous motor, and realizes the control of various actions of the hoisting, rotating and luffing mechanisms of the gantry crane model; the electric control simulation panel is connected to the gantry crane model, and the PLC controller displays the actual speed of the motor through the touch screen, so that the trainee can observe the operating status of each mechanism in real time. In step S4, the trainee operates the device by pressing buttons or touching the touch screen on the electronic control simulation panel to control the gantry crane model to perform set actions. During the operation of the gantry crane model, the electronic control simulation panel can simulate different fault scenarios, and the trainee needs to diagnose and troubleshoot according to the simulated fault phenomena. In step S5: after the operation is completed, the trainee performs fault diagnosis and troubleshooting based on the fault scenarios randomly generated by the device; the trainee analyzes the cause of the fault and makes adjustments based on the feedback from the simulation panel; During this process, the PLC controller resets each mechanism to its initial position, and the touch screen display device resets its state, ensuring that the device is in its initial state and ready for the next round of training.
