Description

Technical Field

[0001] The utility model relates to the technical field of teaching training devices, and more specifically, to an industrial Internet training device. Background Art

[0002] With the rapid development of industrial automation, controllers and Industrial Internet technologies are playing an increasingly important role in modern industry. Cultivating practical skills in these technologies is crucial, especially in teaching and practical training. Traditional training equipment is primarily used in courses such as "PLC Technology," "Computer Control Systems," and "Industrial Internet Edge Data Acquisition." However, its functionality is relatively limited, typically limited to indicator lights, buttons, DIP switches, and basic analog input and output. These devices mostly rely on physical objects and lack virtual-physical simulation objects. This makes them unable to simulate diverse industrial objects across multiple scenarios, severely limiting students' understanding and practical skills in complex control systems. Furthermore, existing equipment often lacks motion control objects, making it difficult to demonstrate the controller's motor control characteristics and multi-axis synchronous control capabilities. Furthermore, traditional equipment also has significant shortcomings in process control and pulse control, making it impossible to fully verify PID control algorithms and pulse input and output characteristics. The Industrial Internet Gateway experimental system supports a limited range of sensor types and bus protocols, and lacks comprehensive edge data acquisition and computing capabilities, further hindering students' learning and application in the Industrial Internet field.
