Wireless multimedia interaction teaching terminal

Abstract

The invention belongs to the field of multimedia wireless interaction teaching, and specifically relates to a wireless multimedia interaction teaching terminal. The wireless multimedia interaction teaching terminal comprises a wireless receiving terminal box and a remote controller. The wireless receiving terminal box is provided with a remote control change-over switch, an audio output port, a power supply input port, and a VGA output port, an HDMI output port and a power supply output port which are used for corresponding connection with a projector. The wireless receiving terminal box is internally provided with a WIFI wireless transmission module, a signal conversion module, a power supply conversion module and a remote control module. The WIFI wireless transmission module receives signals of a portable mobile terminal device and supports the 802.11b / g / n protocol. Original wired signal connection is replaced by the terminal, wireless transmission of teaching multimedia signals is realized, the mobility of a teacher is ensured, and the teacher can walk into students and also can directly write and make marks on a screen of the portable mobile terminal device, so that blackboard writing by chalks is totally replaced, and the pollution and damages are reduced.

Description

technical field [0001] The invention relates to a wireless multimedia interactive teaching terminal, which belongs to the field of multimedia wireless interactive teaching. Background technique [0002] In classroom teaching, whiteboards or multimedia touch all-in-one machines are generally used for multimedia interactive teaching, and teachers complete the demonstration of multimedia teaching resources by directly operating on the corresponding screen. Teachers can only demonstrate, but cannot mark and write on the corresponding resources, which is inconsistent with traditional learning habits, and the focus is not prominent; and teachers are "fixed" in front of the screen during the teaching process, and cannot conduct real-time observation and interaction among students ; It is inconvenient for the existing two types of equipment to use network resources, and only local teaching resources can be used, which does not meet the teaching needs in the "Internet +" environment;...
