Ultra-large screen touch infrared electronic whiteboard integrated machine

Abstract

A super-large-screen touch-control infrared electronic whiteboard integrated machine comprises an infrared touch electronic whiteboard, a frame assembly, a projector and a single-chip microcomputer control device; The infrared touch electronic whiteboard has a rectangular structure and comprises a high-strength steel plate base layer and a honeycomb aluminum sandwich layer, wherein the outer surface of the honeycomb aluminum sandwich layer is sprayed with a composite wear-resistant material layer and infrared touch strips are installed around the honeycomb aluminum sandwich layer; The frame assembly comprises a left frame, a right frame, an upper frame and a lower frame, and is arranged around the infrared touch electronic whiteboard; Compared with the prior art, the invention has the advantages of realizing multi-touch control and dust-free teaching, multi-use of one board, wear resistance and compression resistance, and can be used in combination with a plurality of other equipments.the machine realizes a one-key anti-touch, fast switching between common tablet mode and hand-touching multimedia mode, the integration design, occupies the small space, the high screen proportion, and beautiful vision.

Description

【Technical Field】 [0001] The invention relates to the technical field of multimedia teaching, in particular to a super-large screen touch infrared electronic whiteboard integrated machine. 【Background technique】 [0002] In modern society, people pay more and more attention to education, and at the same time, more and more facilities and funds are invested in education. However, in the traditional teaching and listening mode, there is often a classroom and a blackboard. A large amount of lesson preparation content cannot be displayed on the blackboard because it takes time and effort to write all of it. If most of the content is spoken, only very little content is written on the blackboard. , Students are often unable to take notes completely, which greatly affects the efficiency and quality of lectures, and for information that needs to be repeatedly played to remind the lecturers, such as some notices or key points of lectures, if they stay on the blackboard, they will occupy w...

Problems solved by technology

However, in the traditional teaching listening mode, there is often one classroom and one blackboard, and a large amount of lesson preparation content cannot be displayed on the blackboard, because it takes time and effort to write all of it, and if most of the content is told orally, only a small amount of content is written on the blackboard , the students are often unable to take notes completely, which greatly affects the efficiency and quality of the lectures, and for the information that needs to be played repeatedly to remind the listeners, such as some notices or lecture points, if they are kept on the blackboard, it will take up writing space , affects the efficiency of class, and if it is erased, it will not be able to play the role of multiple reminders, and the traditional blackboard cannot play text, pictures and videos. This teaching mode is still the mainstream in China

The multimedia teaching mode adopts a combined structure of a computer host, a projector and a video screen. The video screen is in a lifting mode, or a video screen is on the left and a blackboard is on the right. Both of them have high requirements for the space of the classroom. The application of equipment in teaching has failed to truly combine traditional education with modern multimedia equipment to achieve intelligence; in addition, there is also a multimedia teaching mode that uses electronic whiteboards, but due to the large number of equipment used in this teaching mode, the screen-to-body ratio Small, the general classroom will have insufficient space after installation, the function is single, and the operation is cumbersome. The electronic whiteboard can only be used as a touch screen, and it is easy to be damaged. When writing with brushes or chalk, another blackboard should be spared
