PLC-based electrical automation control teaching system

Abstract

The invention belongs to the technical field of multi-functional teaching systems and discloses a PLC-based electrical automation control teaching system. The system is provided with a pedestal. Universal brake wheels are arranged under the pedestal. A first lifting device is arranged on the left upper side of the pedestal. The bottom end of the first lifting device is fixed to the pedestal through bolts, the top end of the first lifting device is connected to a connecting plate, and the connecting plate is connected with a projection white board through screws. A second lifting device is arranged on the right side of the first lifting device. The bottom end of the second lifting device is fixed to the pedestal through bolts, and a display is fixed on the top of the second lifting device through bolts. The display is equipped with a loudspeaker and a lighting lamp. A PLC, a wireless receiving device and a PLC special power supply are arranged inside the pedestal. The PLC-based electrical automation control teaching system is simple in structure and low in manufacturing cost, the height of the projection white board is convenient to adjust, the brightness of the whole display is high, and the height of a body of the board is convenient to adjust. Intelligent control can be realized through the PLC, and normal classroom teaching will not be affected. The teaching system is convenient to use and is highly practical.

Description

technical field [0001] The invention belongs to the technical field of multifunctional teaching systems, in particular to a PLC-based electrical automation control teaching system. Background technique [0002] Electrical engineering and automation is a new discipline in the field of electrical information, but because it is closely related to people's daily life and industrial production, it develops very rapidly and is relatively mature now. It has become an important part of the high-tech industry, widely used in industry, agriculture, national defense and other fields, and is playing an increasingly important role in the national economy. Its tentacles extend to all walks of life, ranging from the design of a switch to the research of aerospace vehicles. Students in this major can engage in work in the fields of system operation, automatic control, power electronics technology, information processing, test technology, research and development, economic management, and e...

AI Technical Summary

Problems solved by technology

[0004] (1) The traditional teaching device has a single function, is inconvenient to use, has poor practicability, and has no PLC control system, which cannot meet the needs of modern electrical automation majors

[0005] (2) The signal-to-noise ratio of the frequency overlapping control signal of the existing PLC controller is strong, which directly affects the transmission of the signal, making the signal unstable, poor in transmission quality, and reducing the quality of teaching
