Multimedia-function integrated intelligent interactive blackboard

Abstract

The invention discloses an intelligent interactive blackboard with integrated multimedia functions, which comprises a main board body, a display screen arranged on the surface of the main board body, an internal computer arranged in the main board body and used for playing multimedia files on the display screen, And a multimedia signal acquisition module arranged in the main board body for receiving signals sent by external electronic devices through wireless communication to make the display screen output preset content signals, and the multimedia signal acquisition module is connected with the internal computer signal connection. In this way, the present invention uses the central control function of the multimedia signal acquisition module to receive signals from external electronic devices through wireless communication, which can realize the use requirements of all multimedia functions in the multimedia classroom, without using too many cables, and can reduce the number of multimedia classrooms as much as possible. The number and complexity of wiring within the system reduce the wiring cycle and cost, simplify user operations, and improve teaching effectiveness and efficiency.

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
