Visual interactive electromagnetic wave experiment teaching system and control method

Abstract

The invention discloses a visual interactive electromagnetic wave experiment teaching system, which is composed of an experimental platform subsystem, a microwave transmitting and receiving subsystem, and an upper / lower computer operation control subsystem. The experimental platform subsystem is used for collecting the change of the electromagnetic wave, The microwave transmitting and receiving subsystem sends the electromagnetic waves and collects the electromagnetic wave changes to transmit to the upper / lower computer operation control subsystem. The upper / lower computer operation control subsystem handles the received electromagnetic wave changes and forms the image, and is also used for controlling the microwave transmitting and receiving subsystem to send the electromagnetic waves. The invention also discloses a control method based on the system, which includes checking the data of the sensing system; displaying the human-computer interaction interface; selecting the experimental items, functions and parameters; the microwave transmitting and receiving subsystem transmitting the electromagnetic wave; receiving the antenna receiving signal, and imaging the electromagnetic wave. The problems that the theory of electromagnetic wave in teaching the electromagnetic wave is difficult to digest and the theory is difficult to be connected with the practice are reduced. The virtual interactive electromagnetic wave experiment teaching system can support a wide variety of experiment design types, manifestations are vivid and learning autonomy and consciousness are stimulated, which is conducive to the cultivation of knowledge learning and innovation ability.

Description

technical field [0001] The invention relates to the field of teaching experiment instruments, in particular to a visual interactive electromagnetic wave experiment teaching system, and also to a control method based on the system. Background technique [0002] "Electromagnetic Field and Electromagnetic Wave" is a technical basic course required for undergraduates majoring in electronic information and electrical information in colleges and universities. The current traditional demonstrative and verification experimental teaching methods emphasize the unity of the teaching process and the teacher's dominance, ignoring the subjectivity and individuality of the students, so that the experimental teaching process suppresses the autonomy and creativity of the students, which is not conducive to the cultivation of students The cultivation of innovative spirit and creative practical energy. At present, the traditional demonstration department and verification in colleges and unive...

Problems solved by technology

In addition, the device is bulky, has many auxiliary facilities, and the experimental process is cumbersome. It is difficult to carry out innovative and design experiments. The visualization effect is not obvious. The learners are in the passive cognitive process of verifying the theory, and it is difficult to popularize it in colleges and universities.

[0004]In recent years, a small number of colleges and universities have tried to use computer simulation technology, using simulation software such as matlab and HFSS to carry out the visual virtual experiment teaching of "electromagnetic field and wave". To realize the virtual image simulation of "electromagnetic waves and electromagnetic waves", users are required to have the ability to use computer simulation software proficiently. Simultaneously, the simulation users need to have a certain degree of electromagnetic wave theory and drawing skills in the modeling process, which relatively improves the teaching of electromagnetic fields and electromagnetic waves. In the environment of limited class time resources in colleges and universities, it will invisibly increase the additional burden on teachers and students of "Electromagnetic Fields and Waves", making it difficult to popularize in colleges and universities
