Electronic board teaching device and its operating and controlling method

Abstract

The device comprises electronic board, projector, infrared positioning receptor, command sender, and computer. Characters are as follows: patented product of photosensitive hydrolysis dust free plate is adopted in the board; receptors are fixed at two up corners of the board; signal intensifier is installed behind the faceplate, and conversion socket is on the side of the board. Receptor through signal intensifier and conversion socket is connected to RS232 interace. Data signal through signal intensifier are transmitted between the receptor and computer. Operating the device and controlling method are executed by teaching main program of the electronic board. The board possesses features of large size, no retroreflection, and good visual effect. Controlling functional menu and operation of main program, operation system and other application programs run under multiple threaded interactively. The invented device integrates traditional tool with computer and network teaching resources.

Description

1. Technical field [0001] The invention belongs to electronic equipment for teaching and lectures, and relates to an electronic teaching device composed of a computer, a projector, an electronic board, and an operation and control method. 2. Background technology [0002] With the rapid development of electronics and computer technology, and the arrival of the era of digital communication and network technology, teaching electronic equipment in academic lecture halls, various conference rooms, and school classrooms are constantly being updated. At present, more advanced equipment is composed of computers, projectors and electronic boards. Most of the panels of electronic boards are mainly high-reflective whiteboards, so electronic boards are commonly called electronic whiteboards. Brand products at home and abroad include Canadian Smart, Japanese Panasonic, German plus, American Ebeam portable system, Tianjin Dide, and Sino-foreign joint venture brands Top2000, Zhonghe Tianb...

AI Technical Summary

Problems solved by technology

[0003] 1. The board size of the electronic board is still small, and there is no electronic board with a length of more than 2 meters. Due to its small size, it does not meet the teaching requirements of school classrooms, medium and large conference rooms, and cannot meet the teaching requirements of many people.

[0004] 2. The board surface of the electronic board is a highly reflective whiteboard. The reflection will make the viewing angle smaller. If the angle exceeds a certain range, people will not be able to see the content displayed on the board.

[0005] 3. The teaching resources of the lecture computer are limited by the special program interface and file format, and the content in the computer cannot be fully utilized

[0006] 4. The electronic board is afraid of wear and scratches (the board is made of special materials). These damages will affect the clarity of the teaching display and the service life of the electronic board

[0007] 5. Computer and network teaching resources cannot be fully utilized on the podium

[0008] 6. One board cannot be used for multiple purposes, and the purpose is single. For example, when the power is off, it cannot be used like an ordinary whiteboard, and the writing pen and eraser can not be used to continue teaching.

[0009] 7. If the handouts and texts are not stored in the computer in advance, the electronic board cannot be used for teaching

[0010] 8. The electronic board has a lot of hardware, which is not convenient to use and prone to failure

[0011] 9. Electronic boards and equipment have poor anti-grid pollution capabilities, so that teaching equipment cannot work normally
