Embodiment 1

[0027] Embodiment one is basically as attached figure 1 with figure 2 Shown: including a control module, a storage module for storing teaching content, a display module 15 for displaying teaching content, a writing module for writing teaching content, a supervision module for teaching supervisors to know teaching progress, A drawing module for drawing graphics on the writing module in auxiliary economic teaching content and an acquisition module for obtaining the drawn graphics information.

[0028] The supervision module is connected to the control module by wireless communication. The supervision module is the mobile phone terminal of the supervisor of the educational affairs. The control module can use the existing AT89S51 single-chip microcomputer. The control module is electrically connected to the wireless communication module, and the control module is wirelessly connected to the supervision module through the wireless communication module. The wireless communication ...

Embodiment 2

[0036] The difference with Embodiment 1 is that, if Figure 4 As shown, a plurality of induction coils are evenly buried in the wall 1 corresponding to the writing board 2, the axes of the induction coils are perpendicular to the horizontal plane, and each electromagnetic coil is connected in series with a current-limiting resistor through a wire to form a closed loop, and each electromagnetic coil is electrically connected to The control module, the writing board 2 is equipped with a brush, the inside of the brush is embedded with a magnet, and a water spray pipe 16 is laid on the wall 1 above the writing board 2, and the water spray pipe 16 is evenly opened on one side of the writing board 2. Each water outlet hole is provided with a normally closed electromagnetic switch, the electromagnetic switch corresponds to the induction coil one by one, and the electromagnetic switch is electrically connected to the control module.

Abstract

The invention relates to the teaching information technology field and particularly relates to a multimedia system for economics teaching. The system includes a control module, a storage module, a display module and a writing module and further includes a supervision module, a drawing module and an acquisition module which are for a teaching supervisor to learn the teaching progress, wherein the supervision module and the control module are in wireless communication connection, the drawing module is used for assisting drawing of graphs of the economics teaching content on the writing module, the obtaining module is used for obtaining the graph information after drawing completion, a completion signal is sent by the drawing module to the acquiring module after drawing is completed, the graph information is sent by the obtaining module to the control module according to the completion signal, and the graph information is sent by the control module to the supervision module. The system isadvantaged in that drawing is facilitated in the economics teaching process, the drawing speed is improved, delay of the teaching progress is reduced, the graph information is sent to the teaching supervisor after drawing is completed, and the teaching progress is timely supervised by the teaching supervisor.

Description

technical field [0001] The invention relates to the field of information technology teaching, in particular to a multimedia system for economic teaching. Background technique [0002] Economics is the study of the laws of human economic activities. Economics is also a basic course in various colleges and universities. The teaching of economics involves the theoretical teaching of various economic activities and the corresponding relationship between various parameters in economic activities. Correspondence is generally expressed graphically, such as bar graphs and curve graphs. [0003] In economics teaching, teachers will draw various graphs to show the relationship between various parameters. Although the graphs are displayed through presentation slides, teachers still draw graphs directly or use rulers as drawing references when drawing graphs, or Draw the graphics directly, and explain the knowledge to the students through the process of drawing the graphics, especially...
