Teaching system and method for deepening understanding of measurement principle of testing line

Abstract

The invention belongs to the field of teaching systems, and particularly relates to a teaching system and method for deepening understanding of the measurement principle of a testing line. The teaching system and method can deepen understanding of the measurement principle of the testing line of a measuring element by students. The teaching system comprises a testing line measurement principle laboratory box, a server and a user side which comprises a data input module and a data display module; the input module is used for inputting circuit parameter data by the students, and the data comprise theoretical data calculated by the students according to known parameters in a testing circuit and experimental data obtained through measurement; and the display module is used for displaying the theoretical and experimental circuit parameter data and comparative results. The active thinking ability of the students is advantageously improved instead of passive and mechanical operating according to book requirements, thus the students can more deeply understand the measurement principle of the current testing line, and the operational ability and the problem independent analyzing and solving ability are improved.

Description

technical field [0001] The invention belongs to the field of teaching systems, and in particular relates to a teaching system and method for deepening the understanding of the principle of test line measurement. Background technique [0002] Circuit experiment is a professional basic experiment for students of electronic information in colleges and universities and vocational schools. The experiment content involves the use of basic electronic instruments, the verification of basic circuit theorems, the observation of basic circuit phenomena, etc. The purpose of the experiment is to help students improve their hands-on ability, digest understand the theoretical content. The most basic operation in circuit experiment is to measure branch voltage and current. The method of measuring voltage is to connect a voltmeter in parallel with the branch under test, and the method of measuring current is to connect an ammeter in series with the branch under test. These two most basic m...

Problems solved by technology

There is no problem in this method to realize the measurement of the current, the measurement principle of the test line, and the experimental box. However, during the experiment, many students just operate and measure mechanically according to the requirements of the experimental textbook. Although the measured data is correct, they do not understand it. Why do you need to operate in this way, without understanding the principle of this measurement method
