Black box system used in electronic circuit experiment

Abstract

The invention provides a black box system used in an electronic circuit experiment. The system comprises a PC upper computer, a main control computer, a black box and operation software containing a black box database. The main control computer is a control system that takes a singlechip as a core and is composed of the singlechip, a radio frequency card reader, an MAX232 convertor and a mini-printer. The black box is internally encapsulated with a tested circuit module and a radio frequency card chip. The card reader in the main control computer reads the card number information of a radio frequency card built in the black box, the database of the black box is built in the PC upper computer, and the main control computer and the PC upper computer compare the card number information with the database through a communication link, thus obtaining the parameters built in the black box. In order to further promote the teaching reform of experimental courses, the invention provides an electronic circuit experiment and examination black box system to be used for 'circuit fundamental' and 'simulation circuit' course experiment and examination, thus creating a new path of experiment and examination.

Description

(1) Technical field [0001] The invention relates to an experiment device, in particular to an identification and management system suitable for electronic circuit experiments and examinations in colleges and universities. (2) Background technology [0002] It is difficult for all colleges and universities to set up comprehensive and designed experimental projects, diversify experimental content, and conduct experimental course assessment. In the current electronic circuit experiment teaching process, students are passive and subordinate. As long as they follow the process explained by the teacher and the wiring diagram in the experiment instruction book, they can easily complete the experiment without using their brains; There is no set of experimental circuit diagrams, which leads to similar experimental test results, and plagiarism is common among students in the experimental process; this greatly weakens the role of experiments in cultivating students' practical ability, ...

In the current electronic circuit experiment teaching process, students are passive and subordinate. As long as they follow the process explained by the teacher and the wiring diagram in the experiment instruction book, they can easily complete the experiment without using their brains; There is no set of experimental circuit diagrams, which leads to similar experimental test results, and plagiarism is common among students in the experimental process; this greatly weakens the role of experiments in cultivating students' practical ability, and even lacks the cultivation of students' innovative ability

[0003] At present, we have not found the entity of the black box system used for electronic circuit experiments and examinations, nor have we found any literature records about the black box system for electronic circuit experiments and examinations
