Abstract
The utility model relates to a multimedia central controller. The multimedia central controller comprises a controller main body; a keystroke area and an interface area are arranged outside the controller main body; and a dust cap which is vertically telescopic is arranged outside the interface area. Preferably, the dust cap comprises a mounting shaft and soft cloth, wherein the mounting shaft is mounted at the lower part of the interface area, and the soft cloth is wound on the mounting shaft; and a pull handle is arranged at the end part of the soft cloth. In the utility model, an interface which is easily polluted by dust and the like is protected by the dust cap, the interface can be used by only opening the dust cap, and the functions of dust prevention and pollution prevention can be achieved by closing the dust cap after the using of the controller is finished, so that the multimedia central controller is very convenient in use. Meanwhile, the keystroke area is covered by frosted surface paste; therefore, the dustproof capability can also be well improved.
Description
Technical field
The utility model relates to a kind of multimedia central controller.
Background technology
Along with the continuous development of society with science and technology, information interchange also just becomes more and more frequent, more and more important with linking up.Equipment such as various audio-visual equipment, projector equipment are popularized gradually, get into all trades and professions rapidly thereby driven beginning such as meeting central control system.Present meeting room, electronic teaching chamber etc.; It not an in the past single microphone of the chair in a dais; The substitute is various advanced persons' multimedia conferencing and teaching equipment; Most basic as: projector, video disc player, video tape recorder, video showing platform, multimedia computer, electronic screen, some large conference rooms also have been equipped with simultaneous interpretation system, electronic voting system, large screen projection, many pictures switched system etc.The use of plurality of devices must bring miscellaneous operation of equipment, as: open the plurality of devices power supply, close light, switch various audio-video signals again and again, constantly switch projected picture ... .. or the like.In this case, a kind ofly can manage and control these equipment concentratedly, can control meeting room, the various resources in classroom and " control of multimedia central authorities " simple to operate, diversified equipment simultaneously and just arise at the historic moment.
With the multi-media classroom is example, and central controller is as the control centre of all educational technology equipments.All educational technology equipment is like video tape recorder in the classroom, video disc player, and projector, electronic screen, sound equipment also has indoor light, and curtain can link to each other with central controller, controlled by it.
The control mode variation of central controller for example can connect computer through serial ports, control in controlling and manage through computer; Control in can connecting through network realizes Long-distance Control; Also can control through the touch-screen centering of current trend.Take the touch-screen control mode to explain; Before the user only need be sitting in touch-screen; Just can operate whole system intuitively; Comprise that system switching, each facility switching, light shading value are regulated, signal switches, the broadcast of signal source and stop, entering and switching, the volume of various integrated modes regulate, and to being used for the meeting sound system of public address; Be used to digital session and the simultaneous interpretation system discussing, decide by vote, vote; The video conferencing system that is used for teleconference; The broad screen projective system that is used for video, the demonstration of VGA signal; Be used to provide the multimedia peripheral equipment of audio-video signal; Be used for the full-automatic Comprehensive Control of systems such as global context facility, system equipment control etc.
As stated, the control functions of the equipments are powerful and in multimedia system, playing the part of important role in the multimedia, so guarantee that its normal operation is the normal one big important prerequisite that guarantees the whole multimedia system.The normal operation that how to guarantee in the multimedia control equipment is except the quality of middle control itself need be rigid in checking up, and regular maintenance also ten minutes is important.And in regular maintenance, the normal operation of control during dust prevention also is directly connected to, because middle control all possesses button, panel jack, panel tone video interface etc., these all are the places that is easy to by dust or the intrusion of other booties.If these places are by pollutions such as dust, intrusion, problems such as button is malfunctioning with regard to causing probably, interface instability have had a strong impact on the normal operation of middle control and even whole multimedia system.
The utility model content
The purpose of the utility model is to the deficiency that exists in the prior art, and a kind of dustproof, antipollution multimedia central controller is provided.
A kind of multimedia central controller comprises the controller main body, and controller main body outside is provided with key zone and interface area, and said interface area outside is provided with the dust cap that can stretch up and down.
Preferably, said dust cap comprises the installation shaft that is installed in the interface area bottom and is wound on the soft cloth composition on the installation shaft that the soft cloth end is provided with handle.
Preferably, described key zone is covered with the frosting subsides.
The utility model will be subject to the interface of pollution such as dust and protect through dust cap, in use, only need open dust cap and get final product, use on the end post-tensioning dust cap just can realize preventing dust, anti-pollution, very convenient.Simultaneously, key zone adopts frosting to paste lid, also can very well strengthen dirt exclusion capabilities.
