Multimedia intelligent interactive all-in-one machine for teaching

Abstract

The invention discloses a multimedia intelligent interactive all-in-one machine for teaching. The multimedia intelligent interactive all-in-one machine for the teaching comprises a main machine module, a radio frequency receiving module, a peripheral interface module, a power module, an input device, an output device and a closed casing. The multimedia intelligent interactive all-in-one machine integrates functions of a television, a personal computer, a digital video disk (DVD) player, a tablet personal computer, a projector, an electronic whiteboard, a loudspeaker box, a blackboard and the like so as to meet requirements of a multi-media classroom. The multimedia intelligent interactive all-in-one machine for the teaching can be used as a common television for remote television teaching, can also be used as a multimedia presentation and intelligent interaction system, improves transmission efficiency and audience interest, has specific module connection design, does not need a projecting device, an independent computer and the like, saves space occupied by the devices, and reduces connection wires between the devices. Compared with a common electronic whiteboard, the multimedia intelligent interactive all-in-one machine for the teaching does not relay on the projector and is clear in projecting images. Due to the single device type, purchase cost is reduced, and installation and debugging difficulty is lowered.

Description

technical field [0001] The invention relates to an interactive all-in-one machine, in particular to a multimedia intelligent interactive all-in-one machine for teaching. Background technique [0002] With the development of educational information technology, multimedia teaching has been vigorously promoted in our country. Computers, projectors, etc. have gradually replaced traditional teaching tools such as blackboards and chalk, and have achieved good results in applications such as teaching training and venue demonstrations. However, there are many problems in the use of the existing combined multimedia teaching system. For example, the content of the desktop computer screen is projected onto the hanging screen through a projector, and it is completely dependent on pre-made courseware.

Problems solved by technology

However, there are many problems in the use of the existing combined multimedia teaching system. For example, the content of the desktop computer screen is projected onto the hanging screen through a projector, and it is completely dependent on pre-made courseware. It is not convenient for teachers to mark and change on-site during lectures. and input, etc.; the projection system requires a dark room environment, which affects the use effect; the projector bulb becomes dark due to prolonged use, and its service life is limited; additional computer systems, projectors, hanging curtains (electronic whiteboards), speakers, and multimedia dedicated podiums are required and other equipment, the layout is scattered, the connection is cumbersome, the space is occupied, and the price is expensive, which brings a lot of inconvenience to the installation and maintenance, and also greatly reduces the stability of the system.
