Description

Technical Field

[0001] The utility model relates to the technical field of teaching and training platforms, and in particular to a multi-axis advanced control and digital twin training platform. Background Art

[0002] Traditional axis control PLC training platforms reduce the number of axis drivers and controllers to save costs, deploying only single- or dual-axis hardware. Communication typically utilizes a single control method, resulting in a deployment number far smaller than that used in actual production applications. Furthermore, to save costs, small PLCs are often used for teaching. The platform's hardware is less comprehensive and comprehensive, preventing students from learning different controller types. This leaves little room for professional development and significantly hinders the multi-axis control capabilities required for actual production.

[0003] Most PLC training platforms only offer a single axis control method for drive axis control. This facilitates device development, resulting in limited coverage of mainstream communication protocols, such as ECAT protocol application, Profinet slave applications, and CANopen control. Traditional inverters often rely on point control and stepper motor pulse control, resulting in simple control and inability to achieve closed-loop control. Furthermore, the limited number of axes controlled makes them inappropriate for production environments where dozens or even dozens of axes may be required.

[0004] Currently, most training platform axis control applications are focused on single screw slides, synchronous belts, and linear modules. These simple applications are often not combined, and each platform typically only features one basic application. This multi-axis drive solution places high demands on platform network design, hardware design, and cost.

[0005] At present, the application scenarios of general training platforms are too simple. They do not adopt advanced application scenarios such as axis cam control, motor drag system, and robot multi-axis control. They do not meet the requirements of actual production scenarios and are disconnected from actual axis applications. The combination of multiple scenarios has high requirements for platform development technology and needs to be combined with different production environments.

[0006] Traditional PLC training platforms usually use HMI touch screens to display corresponding control information. They cannot directly display real-time axis posture or process scene status, and cannot directly switch between different scenes. If teaching directly in industrial scenes, there will be great safety risks for students. Without actual production scenes, it is impossible to understand the actual production processes required, which is not conducive to students' learning and subsequent work in the society.

[0007] In summary, the current PLC training platform has the following defects:

[0008] 1. Low comprehensive hardware capabilities:

[0009] Most equipment doesn't use hardware from the same manufacturer, and manufacturers don't offer complete automation solutions. This results in inconsistent interfaces for each hardware module, complex communication configuration, and poor compatibility between different hardware components. For example, domestic or Japanese PLCs can't use ProfineIT with Siemens slaves. As a result, students often lack a thorough understanding of the communication methods used in several mainstream PLCs. Therefore, this equipment utilizes exclusively domestically produced hardware from Inovance. Furthermore, with a limited number of drivers, this doesn't allow for exposure to the programming and design background that's similar to actual production.

[0010] 2. Low platform diversity:

[0011] Training platforms are often designed for specific types of motion control tasks (such as screw slides and synchronous belts), making them difficult to adapt to the application needs of different fields and industries, as well as applications of varying complexity. This lacks application diversity and is particularly challenging for students who will face complex scenarios in their future work.

[0012] 3. Few advanced industrial application scenarios

[0013] In the hardware and software design of training platforms, basic teaching application scenarios are usually adopted, such as traffic lights, material transport carts, musical fountains, etc., which are inconsistent with actual industrial application scenarios. This is because it is necessary to cultivate students' basic development capabilities, but they are disconnected from actual applications. Students who want to continue to improve their capabilities or understand the actual industrial production environment can often only be exposed to similar industrial scenarios after graduation. In the comprehensive training, there is a lack of teaching and training platforms for high-end PLC applications.

[0014] 4. Digital Twins Controlled by Platforms

[0015] Traditional training platforms often use HMI as the display and interactive screen, which has poor display and control effects for training processes, cannot be seen intuitively, cannot achieve close to actual production applications by switching between different production scenes, and cannot reduce safety hazards in teaching.

[0040] Please refer to Figure 1 and Figure 2 The present invention proposes a multi-axis advanced control and digital twin training platform. The preferred embodiment of the multi-axis advanced control and digital twin training platform of the present invention includes: a shell, a controller component, a multi-axis drive control component and a motor application system arranged on the shell, the controller component includes a small PLC1, a medium-sized PLC2 and a digital twin display and control all-in-one machine 4, wherein the small PLC1, medium-sized PLC2, and multi-axis drive control component are arranged in the middle of the shell, the digital twin display and control all-in-one machine 4 is arranged below the medium-sized PLC2, and the motor application system is arranged above the small PLC1, medium-sized PLC2 and the multi-axis drive control component.

[0041] This embodiment adds the deployment of the small PLC1 and the medium-sized PLC2, so that students have a certain understanding of the models of the entire system. It can also realize two controllers in one system, thereby improving the reuse rate of the system.

[0042] In this embodiment, all electrical devices use a unified standard interface.

[0043] The motor application system includes two servo motor synchronous belt control systems 12, and the multi-axis drive control component includes an EtherCAT servo driver 6 and a CANLink servo driver 7. One motor in the two servo motor synchronous belt control systems 12 is connected to the EtherCAT servo driver 6, and the other motor is connected to the CANLink servo driver 7. The main connections are the power supply line and the encoder feedback line to achieve closed-loop control, providing the hardware foundation for high-end control applications such as multi-motor linkage, tracking shears, flying shears, and cam control, filling in the gaps in high-end industrial application knowledge and practical application for students.

[0044] The motor application system also includes a servo motor and a three-phase asynchronous motor pairing system 11, and the multi-axis drive control component also includes a CANOPEN servo driver 8 and an EtherCAT inverter slave station 10.

[0054] Universal wheels are arranged at the four corners of the bottom of the shell.

[0055] This embodiment deploys different data twin models on the integrated display and control machine, and then connects it to the PLC through a communication data module, so as to bring actual application scenarios into the training platform. This allows students to understand the differences and process details of each application scenario, and can also solve the safety hazards that may occur due to students' unfamiliarity with industrial products during the initial learning period.
