Multifunctional data acquiring-outputting teaching experimental device and control method thereof

Abstract

The invention relates to a multifunctional data acquiring-outputting teaching experimental device and a control method thereof. The device comprises a single chip microcomputer, a digital-quantity input interface, a digital-quantity output interface, an analog-quantity input interface, an analog-quantity output interface and a display interface, wherein the single chip microcomputer stores a control program, is a control core of the whole device, and can acquire or output digital / analog signals; the digital-quantity input interface is formed by connecting the single chip microcomputer to a digital-quantity input terminal through an I / O extension module; the digital-quantity output interface is formed by connecting the single chip microcomputer to a digital-quantity output terminal through a latch; the analog-quantity input interface is formed by connecting the single chip microcomputer to an analog-quantity input terminal through an analog-quantity acquiring module; the analog-quantity output interface is formed by connecting the single chip microcomputer to an analog-quantity output terminal through an analog-quantity output module; the display interface is formed by connecting a display terminal with an I / O pin of the single chip microcomputer; and the control program comprises a main program and an interrupt service processing program. The device has the advantages of numerous functions, strong flexibility, great applicability to teaching, graduation design and extracurricular practice of students, reuse capability, plentiful interfaces, good software generality and good extensibility.

Description

technical field [0001] The invention relates to a multifunctional teaching instrument experiment equipment in the technical field of data acquisition and digital communication, in particular to a multifunctional data acquisition and output teaching experiment device and a control method thereof. Background technique [0002] Teaching instrument is an important link in teaching, it enables students to practice the theoretical knowledge learned in the classroom, but because conventional teaching instruments are developed by special manufacturers, due to technical confidentiality or other aspects The reason for this is that the openness of the entire teaching instrument is not very strong, and it can only be operated according to the steps stipulated by the manufacturer. Students cannot customize or practice the required experimental content according to their own ideas. Due to financial reasons, it is impossible for the school to purchase a variety of experimental devices, and...

AI Technical Summary

Problems solved by technology

Therefore, students are not very interested in teaching experiments during the learning process, and because students do not have extra funds to realize teaching experiments by themselves during the learning period, this makes teaching and experiments disconnected in time and space

[0003] With the popularization of education, the number of students has increased sharply, the original teaching equipment cannot meet the existing use requirements, and the contradiction between supply and demand is gradually intensifying

At the same time, with the development of electronic technology, sensor technology, and communication technology, experimental equipment also needs to be further updated, and it is unrealistic to achieve synchronous updating of teaching equipment, which cannot meet the needs of contemporary teaching experiments.

In addition, due to financial reasons, many graduation projects remain on paper and have not been tested in practice. The practical ability of graduates has not been improved and exercised, and it is difficult to adapt to today's employment requirements.
