Teaching demonstrating device for demonstrating relationship among point, line and plane

Abstract

The invention discloses a teaching demonstrating device for demonstrating a relationship among a point, a line and a plane, comprising an STC (Sensitivity-Time Control) single chip microcomputer control module, a display module and a power supply; the STC single chip control module is connected with the display module and is used for controlling work statuses of the display module; the display module comprises a displaying part and a driving part; the displaying part is an LED dot matrix; the driving part commonly consists of a 74LS154 and a 74HC595 and is used for respectively controlling row displaying and line displaying in the LED dot matrix; the power supply supplies electric power to a main control circuit and a display circuit; and the STC single chip microcomputer control module is used for receiving control signals, processing the control signals, inputting row signals and line signals respectively into the LED dot matrix through the displaying part and the driving part, controlling LED colorful lamps in the dot matrix to display in a manner of point-line-plane. In the teaching demonstrating device disclosed by the invention, the LED dot matrix is controlled through the STC single chip microcomputer to demonstrate phenomena of moving a point to form a line and moving a line to form a plane, and vividly represent the physical phenomena, so that students can understand easily.

Description

technical field [0001] The invention relates to a demonstration device, in particular to a teaching demonstration device for demonstrating the relationship between points, lines and planes. Background technique [0002] With the development of the times and human beings, today's children's curiosity is getting stronger and stronger. They are full of desire to explore the unknown world, but due to their age, their intelligence has not yet fully developed, and it is difficult for teachers to rely on oral narration and PPT demonstrations. Let the students fully understand, the students are still confused. Use relevant models to assist teaching and let students practice it by themselves. This will not only make boring knowledge more vivid, make it easy for students to accept, but also stimulate students' interest in learning. At the same time, it can also reduce the teaching burden of teachers. [0003] Now there are many teaching demonstration devices that demonstrate various...
