Signal and system experiment device capable of remote parameter regulation and implementation method thereof

Abstract

The present invention provides a signal and system experiment device capable of remote parameter regulation and an implementation method thereof. The device comprises an upper computer system, a plurality of terminal experiment systems arranged in a distribution mode, a wireless communication system and a power supply system. Through adoption of the signal and system experiment device capable of remote parameter regulation, teachers can modify internal configuration parameters of a terminal experiment system through a remote-end upper computer system in a wireless receiving-transmitting mode,because students cannot directly obtain signal or system change from representation, the device can guide the students to start from the outermost input and output relation of the system and employ series of tests to explain signal features and analyze the system features so as to provide paths for students to eminently display the core content of a linear time invariant system analysis theory andprovide basis for teachers to perform quantization evaluation of students' experiment work.

Description

technical field [0001] The invention belongs to the technical field of signal and system characteristic testing experimental devices in the teaching of communication engineering, electronic information engineering, automation and other related majors, and in particular relates to a signal and system experimental device and an implementation method capable of remote parameter adjustment. Background technique [0002] The "Signal and System" course is a core professional course for information undergraduates. The corresponding course experiments are mostly based on the positive verification of theoretical knowledge points. Although it has played a role in assisting theoretical teaching to a certain extent, the current experiment However, there are obvious limitations in the content, which are restricted by the platform system, mainly reflected in: [0003] (1) There is a lack of content links to examine the internal correlation of knowledge points from multiple angles, and the...

AI Technical Summary

Problems solved by technology

[0003] (1) There is a lack of content links to examine the internal correlation of knowledge points from multiple angles, and the simultaneous adjustment of multiple parameters of signals or systems can easily cause students to be troubled by analysis and judgment;

[0004] (2) The consistency of experimental data, analysis and conclusions is remarkable, and the assessment of students' experimental links lacks sampling points and quantitative evidence

[0005] The resulting "signal and system" experiment presents students with a simple and intuitive expression of a single knowledge point, which makes it difficult for students to think about related issues, and what is provided to teachers is a quantitative evaluation that cannot be done.

[0006] At present, the platform systems produced and used in the application field of signal and system characteristics experiment teaching at home and abroad are slightly different in terms of experimental design architecture, system implementation mode, and platform processing technology, but they are all local-side stand-alone operations, and no one has been found.
