Along with the development of infrared communication technique, the FIR technology of the existing 4M of having transmission rate is widely used, and transmission range can reach more than 30 meters, in the utility model, the infrared remote receiver arranging is as the audio collection port of video conference terminal, by supporting infrared emission end on peripheral sound collection equipment, transmit voice data information using infrared ray as carrier.It is as the one of radio communication, compared with radio communication, because its ratio of performance to price is high, realize simple, be convenient to high-speed applications, space access, economy, the more important thing is, the anti-electromagnetic interference feature that it has, in the time of its communication mode as video conference terminal and peripheral sound collection equipment, can avoid personnel participating in the meeting's communication equipment or the communication quality of other electromagnetic signals interference wireless microphone and video conference terminal.
Further technical scheme is:
Described infrared remote receiver comprises infrared receiving diode, resistance and NPN pipe, and described NPN pipe base stage is connected with control end by resistance, and the grounded emitter of NPN pipe, the collector electrode of NPN pipe connect the backward end of infrared receiving diode; Between the collector electrode of described NPN pipe and the backward end of infrared receiving diode, be also in series with amplifier.
More than arrange in the infrared remote receiver of form, the NPN pipe arranging can be realized the control whether infrared signal is received and have certain signal strength signal intensity enlarging function, and the amplifier further arranging is for further amplifying infrared signal, be beneficial to the voice signal intensity that video conference terminal finally obtains.
Whether suitable, also comprise the loud speaker being connected on central processing unit if directly reproducing with the setting angle of check ancillary equipment for ease of the audio signal that video conference terminal is received, be also provided with digital to analog converter between described loud speaker and central processing unit.
For obtaining more audio signal sample end, also comprise built-in microphone, described built-in microphone is connected with central processing unit, is also provided with analog to digital converter between described built-in microphone and central processing unit.
Also comprise audio output interface, VGA output interface and HDMI output interface, described audio output interface, VGA output interface and HDMI output interface are connected on central processing unit, between described audio output interface, VGA output interface and central processing unit, are also provided with digital to analog converter.
The VGA output interface, HDMI output interface and the audio output interface that arrange are connected respectively to after external equipment, can export respectively analog rgb+HV signal, high-definition digital signal and audio signal to external equipment, be convenient to the sound of other video conference places and picture signal to present in real time in this meeting-place.
The utlity model has following beneficial effect:
In the utility model, the infrared remote receiver of setting, as the audio collection port of video conference terminal, by supporting infrared emission end on peripheral sound collection equipment, transmits voice data information using infrared ray as carrier.It is as the one of radio communication, compared with radio communication, because its ratio of performance to price is high, realize simple, be convenient to high-speed applications, space access, economy, the more important thing is, the anti-electromagnetic interference feature that it has, in the time of its communication mode as video conference terminal and peripheral sound collection equipment, can avoid personnel participating in the meeting's communication equipment or the communication quality of other electromagnetic signals interference wireless microphone and video conference terminal, be conducive to the acquisition quality of conference terminal audio signal.
