Abstract
The invention relates to the technical field of teaching equipment, and particularly discloses a multimedia integrated central control unit. Compared with the prior art, the control host of the multimedia integrated central control unit is composed of a central control unit, a power management module, an audio switching module, a video switching module, a VGA switching module, a projector control device, a port control device and a card swiping electric control device. The power management module, the audio switching module, the video switching module, the VGA switching module and the projector control device are integrated onto a central control unit circuit board. A control panel is in butt-joint with the control host. The control panel is used to realize the control on the keyboard of the control host. For multimedia centralized controllers in teaching and demonstration places, such as a multimedia classroom, a meeting room, a multifunctional hall, an academic report hall, etc., and for the above multimedia environment, the multimedia integrated central control unit can be used to complete the centralized control on equipment, such as a computer, a projector, a notebook computer, a video presenter, a DVD player, a video tape recorder, a recording cassette deck, a power amplifier, an electric screen, a card swiping electric control device, etc.
Description
technical field [0001] The invention relates to the technical field of teaching equipment, in particular to a multimedia integrated central controller. Background technique [0002] With the development of modern educational technology, multimedia classrooms have more and more functions and more and more equipment. The multimedia teaching system of the multimedia classroom is generally composed of a computer, a digital (video) physical display stand, a projector (or rear projection TV), an electronic control screen, a VGA distributor, a wireless public address system, etc. [0003] At present, in the multimedia classrooms under construction and in use, most of the above-mentioned devices are simply integrated through corresponding connections. When teachers use them, they need to operate the switch of each device to turn on these devices. It is cumbersome to use, and different devices need to be operated by teachers. The requirements for teachers Relatively high. The vario...
