1. Overview
DLIM-DT01A digital twin technology application platform uses advanced simulation technology to reproduce the three-layer organizational structure of the industrial Internet collaborative manufacturing platform, presenting the key technologies of the industrial Internet device perception layer, network transmission layer, and application layer in all aspects and the skills students need to master .
The project gives full play to the advantages and characteristics of digital twin technology, from point to surface, to create the field control level, production unit level, workshop level, and factory level course content,
While mastering key technologies such as digital twin modeling and simulation, students also systematically learn key technologies and skills such as high-end CNC machine tools, industrial robots, machine vision, AGV, and MES manufacturing execution systems involved in the integration of intelligent manufacturing systems.
2. The Features
– Eager to learn: The platform adopts a virtual immersion teaching environment, with strong participation of students, and all students can obtain sufficient opportunities for practical training.
– Easy to teach: The teaching and training scenarios are diversified, and the scenarios matched with the platform standards can be selected. Students can also build different industrial production scenarios by themselves according to the industrial automation material library provided by the software, and carry out layout, debugging and production line optimization.
– Easy to test: If the number of physical platforms is insufficient, the assessment can be carried out on the virtual simulation platform first, and then verified on the physical platform.
– Economy: Compared with the physical platform with the same scene, the cost of this platform is greatly reduced, which can effectively reduce the school’s procurement cost and daily consumables investment.
– Safety: The teaching safety of the platform is good, and the safety of equipment and personnel can be effectively protected after virtual reality.
– Efficiency: The efficiency of teaching, training and assessment can be increased by about 6 times.
– Combination of virtual and real: This platform uses real PLC, touch screen and 3D virtual automated warehouse and processing and assembly production line. Students can drive the virtual production line through real PLC to realize the combination of virtual and real.
– Venue: The platform covers an area of about 2*1m, which can meet the training needs of a large number of students in a limited space.
3. Composition of technical equipment
This platform mainly consists of two parts: hardware system and software system.
The hardware system is mainly composed of a console, PLC, touch screen, buttons, and other human-computer interaction equipment, which are used for interactive operation with virtual scenes and equipment.
The software system is mainly composed of PLC programming software, configuration software, industrial robot off-line programming software, and factory automation simulation software.
It is mainly used for practical training tasks such as 3D scene construction, mechanical motion attribute creation, electrical component attribute setting and association, production line virtual debugging, and beat optimization.
Using virtual simulation, offline programming, and a combination of virtual and real technologies, through programming and debugging,
Students can learn to master the basic operation, programming, and communication between equipment such as PLC, touch screen, industrial robot, AGV, laser marking machine, servo motor, and stepper motor.
At the same time, the 3D modeling of production equipment can also save the cost of school equipment procurement, reduce equipment consumption in the teaching process, and carry out efficient teaching work.
