Multimedia-function integrated intelligent interactive blackboard

Abstract

The invention discloses a multimedia-function integrated intelligent interactive blackboard, which comprises a main board body, a display screen which is arranged on the surface of the main board body, an internal computer which is arranged in the main board body and is used for playing multimedia documents on the display screen, and a multimedia signal acquisition module which is arranged in themain board body and is used for receiving a signal, which is transmitted from external electronic equipment and is used for indicating the display screen to output preset contents, in a wireless communication mode, wherein the multimedia signal acquisition module is in signal connection to the internal computer. Therefore, by receiving the signal of the external electronic equipment in the wireless communication mode through a central control function of the multimedia signal acquisition module, a demand of using all multimedia functions of a multimedia classroom can be achieved, and it is unnecessary to use excessive cables, so that the wiring quantity and complexity degree of the multimedia classroom are reduced to the greatest extent, and wiring cycle and cost are reduced; and in addition, user operations are simplified, and teaching effect and teaching efficiency are improved.

Description

technical field [0001] The invention relates to the technical field of electronic appliance control, in particular to an intelligent interactive blackboard with integrated multimedia functions. Background technique [0002] With the development of China's education, more and more teaching equipment has been put into use. [0003] The blackboard is the most widely used and traditional important teaching equipment in the classroom. Teachers can erase and write on the blackboard. However, teachers can only display text or simple graphics on the blackboard. For some courses that are abstract and difficult to understand or involve spatial structures, they often need to watch video files to have an intuitive understanding of the courses. Aiming at this, the multimedia classroom emerges as the times require. Multimedia classrooms are composed of multimedia computers, LCD projectors, digital video display stands, central control systems, projection screens, audio equipment and oth...

Problems solved by technology

[0005] However, the smart blackboard in the prior art does not have various functions of a multimedia classroom, and in the process of installation, construction and use of the smart blackboard, it needs to be connected with other matching electronic devices through various cables, such as network cables, Sound signal lines, video signal lines, etc., which require wiring design in the classroom, when using different electronic devices to connect cables, this will inevitably lead to long wiring cycles, high costs, and various types of cables for on-site use , cable entanglement, cumbersome operation and other problems, resulting in frequent teaching failures and low teaching efficiency
