Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, to make advantage of the present utility model and feature can be easier to be readily appreciated by one skilled in the art, thus more explicit defining is made to protection domain of the present utility model.
Shown in accompanying drawing 1-2, a kind of interactive electric whiteboard with video signal communication function of the present embodiment, comprise electronic whiteboard body 7, the framework 74 of electronic whiteboard body 7 is built-in with and controls mainboard 2, the computer be connected with electronic whiteboard body 7 or dull and stereotyped or mobile phone, this electronic whiteboard body 7 in the present embodiment has video signal and exchanges, many need to use the equipment of USB transmission to be exported by a delivery outlet, touch controllable function, audio frequency is shared, add rights management capabilities, the function that electronic whiteboard and common blank can switch forms, realize that common blank and electronic touch blank are two to be write, real time remote video conference exchanges, the function that easy data line connects.The structure of specific implementation above-mentioned functions is as follows:
The interactive electric whiteboard of this band video signal communication function comprises camera 1, camera 1 is arranged in the upper ledge of framework 74 of electronic whiteboard body 7, camera 1 by connect successively in order to gather image optical lens, in order to image is changed into data-signal optical sensor, in order to data-signal is transferred to computer or controls transfer chip that is dull and stereotyped or mobile phone forms, optical sensor is connected by controls transfer chip and computer or flat board or mobile phone.Optical lens, optical sensor are live and transfer in computer or dull and stereotyped or mobile phone by controls transfer chip in order to enroll on-the-spot meeting, this computer or dull and stereotyped or mobile phone are connected by network and another computer or flat board or mobile phone, and play back on the electronic whiteboard body be connected with another computer or dull and stereotyped or mobile phone, then image transmission is realized, video signal communication function.
The framework 74 of electronic whiteboard body 7 is provided with USBHUB multiplex roles shared device 5, USBHUB multiplex roles shared device 5 to be connected with control mainboard 2.Many are needed to use the equipment of USB transmission to be exported by USBHUB multiplex roles shared device 5 one delivery outlets, reduce winding displacement, make the interactive electric whiteboard of this band video signal communication function clean and tidy, attractive in appearance.Conveniently use, USBHUB multiplex roles shared device 5 is arranged on the below of electronic whiteboard body 7 side.
Electronic whiteboard body 7 can realize touch controllable function, because electronic whiteboard body 7 have employed infrared electronic Trackpad, electronic touch blank comprises at least two infrared cameras 3, optical reflection bar 8, at least two infrared cameras 3 are arranged on framework 74 corner of electronic whiteboard body 7, what present in accompanying drawing 1 is two infrared cameras 3, an infrared camera 3 can certainly be all provided with in four of framework 74 corner, and optical reflection bar 8 is arranged on the four edges of framework 74 of electronic whiteboard body 7, in each infrared camera 3, there is LED light source (not shown), the optical reflection bar 8 on LED light source energy directive opposite, the infrared camera 3 being built-in with this LED light source receives light reflection, if there is no object when electronic whiteboard body 7 enterprising line operate, infrared camera 3 can receive the reflected light of reflection on directive optical reflection bar 8, once have object at the enterprising line operate of electronic whiteboard body 7, LED light source cannot arrive on optical reflection bar 8, then infrared camera 3 does not observe the reflected light of reflection, by this principle, the signal observed is sent to and controls mainboard 2 by two infrared cameras 3, control mainboard 2 by calculating the data of touch point at optical reflection bar 8, obtain touch-control coordinate (X, Y).When arranging four infrared cameras 3, the touch-control of more than 2 simultaneously can be realized.
Electronic whiteboard body 7 can realize audio frequency and share, be because the framework 74 of electronic whiteboard body 7 is built-in with audio extender, audio extender exports sound equipment 4 by least two audio frequency and forms, as shown in Figure 1, audio frequency exports sound equipment 4 and is provided with two, is positioned at the both sides of electronic whiteboard body 7.
Electronic whiteboard body 7 is provided with the fingerprint identification lock 6 run in order to control mainboard 2, adds rights management capabilities, fingerprint identification lock 6 is connected with control mainboard 2.
Be provided with short out-of-focus projection instrument 9 above electronic whiteboard body 7, short out-of-focus projection instrument 9 is connected with control mainboard 2.
Electronic whiteboard body 7 has layer structure, comprises bottom 73, middle layer 72 and superficial layer 71, when not using electronic whiteboard, can write, serve as the function of common blank at the pen of superficial layer 71 topical oil pen or other materials; This superficial layer 71 is provided with high sub-light enamel coating, and (enamel is also enamel, it is a kind of unorganic glass, metal surface is attached to by high-temperature fusion), in order to ensure that watching this electronic whiteboard body 7 from multiple angle can see content electronic whiteboard body 7 clearly; This coating is very firm, can prevent hard object scratch, and serviceable life can reach 20 years; After this coating is write, very easily wiping, leaves no trace, and greatly improves ease of use.Middle layer 72 in honeycomb aluminum structure, due to bottom 73 and superficial layer 71 thinner, middle layer 72 adopts honeycomb aluminum shape structure, ensure that the flatness of superficial layer 71, can not affect touch-control.
