Virtual instrument embedded in comprehensive teaching experiment platform

Abstract

The invention relates to a virtual instrument embedded in a comprehensive teaching experiment platform. The virtual instrument comprises a high-precision measurement function circuit, a high-speed measurement function circuit and a power supply circuit, wherein the high-precision measurement function circuit, the high-speed measurement function circuit and the power supply circuit are respectivelyconnected with the comprehensive teaching experiment platform. The virtual instrument has the advantages that on the basis of meeting the requirements of teaching experiments on the functions and performance, the procurement cost of schools can be obviously reduced; the space resource waste of experiment stations is reduced; the integration of instruments and teaching equipment is realized; and the teaching effect is improved.

Description

technical field [0001] The invention relates to the teaching field, in particular to a virtual instrument embedded in a comprehensive teaching experiment platform. Background technique [0002] In the process of higher education, especially in the teaching process of engineering and science, in order to enable students to better understand the theoretical knowledge in books, corresponding experimental courses are generally offered. One way is that the teacher demonstrates relevant knowledge through the teaching equipment; the other way is that the students directly operate the teaching equipment and conduct hands-on experiments, and through the process of hands-on experiments, they can further deepen their understanding of theoretical knowledge. [0003] At present, the teaching experimental equipment on the market is mainly a variety of special small test boxes or large test benches. These test boxes or test benches only focus on a specific experimental circuit principle, a...

AI Technical Summary

Problems solved by technology

[0004] 1) Every time a school purchases a set of experimental boxes or test benches, it has to purchase corresponding desktop instruments, which increases the purchase cost to a certain extent;

[0005] 2) The volume and weight of traditional desktop instruments are generally relatively large, which makes it impossible to reduce the area of ​​the experimental workstation, which is already relatively tight, and wastes more space resources;

[0006] 3) Traditional desktop instruments are generally designed for scientific research and production, and the indicators of the instruments are generally better, but for teaching applications, the indicators of traditional desktop instruments are often too high, forming a situation of big horses and small carts, resulting in a certain degree of waste of resources;

[0007] 4) The communication between the traditional desktop instrument and the experimental box is inconvenient, which is not conducive to improving the correlation between the two during the experiment process, which is not conducive to improving the experimental experience, such as the synchronization between the experimental circuit and the instrument, the experimental circuit data and the instrument data The relevance of and the writing of experimental reports, etc.

With the continuous development of instrument technology and information technology, virtual instrument technology is becoming more and more mature, and has been widely used in the industrial field, but it has not yet been found in teaching experiments.
