The GL-GD-TZ Optical modulation and demodulation experiment instrument focuses on explaining the principles and implementation methods of amplitude modulation and pulse modulation, helping students to deepen their understanding of the modulation and demodulation principles of light sources.

The GL-DG-T  Electrical and electronic test bench can complete the practical training projects of multiple courses such as circuit analysis, circuit principle, electrical technology, and electronic technology. It can meet the practical training teaching requirements through the training component training. The experiment platform has a complete personal safety protection and equipment safety protection system, provides an intelligent power protection system, and has leakage, overcurrent, short circuit and other protection functions. The platform adopts a modular structure as a whole, and the power supply and instrumentation all adopt an independent hanging box structure. The tasks of each training module are clear, and the operation and maintenance are simple. It is also convenient for schools to choose different training configurations according to their own teaching requirements, which is easy to expand and upgrade later.

The GLDDT motor and electric traction experimental device is suitable for the renovation of existing motor and electrical technology experimental equipment in colleges and universities. It also provides an ideal experimental equipment for the construction or expansion of laboratories in secondary vocational schools, vocational and technical colleges, undergraduate colleges, etc., and for the rapid opening of experimental courses. It provides good conditions for teachers and graduate students to develop or conduct scientific research. This device has a complete and reliable personal safety protection system, and all sheathed terminals are used to ensure experimental safety.

GLPLC-LN network-type programmable controller training equipment consists of core components such as PLC, frequency converter, touch screen, etc. This device integrates programmable logic controller, communication editor, programming software, industrial control configuration software, simulation teaching software, simulation control training hanging box, and real objects. It can intuitively carry out multiple experimental projects such as PLC basic instruction training, PLC practical application simulation and real object control training, and also provide good conditions for high-level design and development experimental training.

After selecting training components such as three-phase squirrel cage asynchronous motors and relays, it can also complete multiple electrical and relay control project training.

The GLGDT modern photoelectric characteristics comprehensive experimental platform is a multifunctional experimental system integrating optics, mechanics and electronics. The system covers a wide range of content and can be used to conduct experiments on the principles, characteristics and performance parameters of various devices such as signal sources and photoelectric detectors used in optical communication, information control and photoelectric detection. It can also conduct a series of photoelectric experiments such as light transmission, application of photoelectric sensors, light intensity analysis, and moiré fringe counting.
