Modular Pneumatic and PLC Training Device for Industrial Automation Vocational Education

This experimental platform is designed based on general textbooks such as "Hydraulic and Pneumatic Transmission Technology and Training" and "Pneumatic Control Technology," and is suitable for undergraduate courses and graduation projects (theses) in mechanical and mechatronics fields. It integrates a programmable logic controller (PLC) with industrial pneumatic components and actuator modules. In addition to conducting conventional basic pneumatic control circuit experiments, it can also perform pneumatic-electrical control circuit application experiments, pneumatic-PLC control circuit design, and other pneumatic technology course designs.

1. Modular components: Each pneumatic component is an independent module with a base plate for easy installation. Various experimental circuits can be built on T-slot universal aluminum alloy profiles, making operation simple and quick.
2. Connection method: The connector adopts a quick-connect type, which is reliable, simple and time-saving to install and disassemble.
3. Pneumatic components: Industrial pneumatic components, reliable and safe. High precision and long service life.
4. System environment: Low-noise (ultra-quiet) working pump station, providing a quiet experimental environment (noise < 50 decibels).
5. Scalable Experiments:

   To adapt to the requirements of the school's experimental teaching reform, reduce verification experiments, increase design-oriented, comprehensive, and exploratory experiments, and develop students' independent and innovative thinking, in addition to completing basic air pressure experiments, it should also be combined with mechanical experimental projects; while ensuring equipment stability, it should provide strong scalability, and the large aluminum alloy panel assembly platform provides the necessary hardware foundation for expansion.

   This equipment can meet the requirements of modern experimental teaching in terms of advancement, openness, and scalability. It fully demonstrates the multi-functionality of the equipment in mechatronics teaching.

   • A. Under the premise of ensuring the existing experiments, hydraulic components can be connected to conduct corresponding integrated hydraulic-gas experiments;
   • B. With hardware support, extended experiments such as feeding mechanisms and excavator mechanisms can also be carried out.
6. Compatibility
   • A. This experimental platform can be compatible with MPS automated logistics system and FMS flexible system.
   • B. The experimental platform's electrical control and hardware components are easily upgradeable and expandable with user-friendly module connections, allowing for combined experiments with various electromechanical, hydraulic, and pneumatic modules. Examples include rotary feeding mechanisms, robotic arms, and automated transport lines. When integrated with electronic simulation software, it can simulate various mechanical applications, such as the application of proportional valves in wind turbines, the working principle of cartridge valves, and the application of mechanical elevators. Furthermore, it can be edited according to the teacher's lecture content.
7. Multiple control modes: pure pneumatic (manual) control circuit, electro-pneumatic circuit using relays, electro-pneumatic circuit using programmable controllers, and configuration control circuit (requires corresponding software and hardware).
8. System Safety Performance: The rated working pressure is 1.0 MPa, making it a safe low-pressure experimental system. The power supply has leakage protection; it automatically disconnects the main power supply in case of leakage (leakage current to ground exceeding 30mA) or phase loss. All control circuits use a safe 24V DC voltage.
