Abstract

The invention relates to the technical field of education and teaching, in particular to an electronic technology experimental box for classroom teaching. The electronic technology experimental box comprises a main board, two daughter boards, an experimental box body and a power supply module, wherein the main board comprises a nixie tube, a dial switch, an indicator light, a logic pen, a main switch, a direct voltage and a short circuit alarm, expansion wiring, an impulse signal source, a single impulse, a fixed resistor-capacitor, an alarm circuit, an A / D or D / A switch, a bread board and other modules. The two daughter boards are respectively a singlechip system board and a programmable system-on-chip board. The size of the singlechip system board is the same with the size of the bread board, thus the singlechip system board is convenient to dismantle and change. The introduction of the programmable system-on-chip board enables online programming to be realized, flexibility and convenience of the experimental box is strengthened, and the introduction of the two daughter boards enables the experimental box to upgrade to a high-performance singlechip system experimental box.

Description

technical field [0001] The invention relates to the technical field of education and teaching, in particular to an electronic technology experiment box for classroom teaching. Background technique [0002] With the development of science and technology, the important role of electronic technology in production and research activities has become increasingly prominent. Electronic technology experimental equipment, that is, analog electronic technology and digital electronic technology experiment box, is an important experimental device for the implementation of electronic technology practice teaching and student innovation in major colleges and universities. At present, the electronic technology experiment box widely used in various colleges and universities is designed for the experimental content of the basic course of electronic technology. This type of experiment box has three significant defects: first, the equipment function of the experiment box is single, and the exp...
