Detailed Description
The invention will be further described with reference to the drawings and the embodiments.
As shown in fig. 1, a photoelectric matrix KVM seat system includes an optical moment transmitting box, a KVM photoelectric matrix end, a management end, and an optical moment receiving box, where the optical moment transmitting box is configured to receive an audio/video source transmitted by an audio/video source end and forward the audio/video source to the KVM photoelectric matrix end, one optical moment transmitting box only receives an audio/video source transmitted by a corresponding audio/video source end, the audio/video source includes an audio signal and a video signal, and the optical moment transmitting box and the audio/video source end are connected by a video cable. The video cable can select for use video transmission cables such as HDMI, DVI, DP, VGA, SDI, CVBS, HDMI-4K, DP-4K, and the optical moment is sent the box and is served and be provided with the port with transmission cable assorted with the audio video source, for example, when adopting HDMI transmission cable to carry out the transmission audio video source, the optical moment is sent the box and is served and be provided with the HDMI interface with the audio video source. The audio/video source end is usually a PC end (i.e. a computer terminal) or other processing terminal with a data sending function, for example, a tablet computer or a mobile phone.
Preferably, an audio power amplifier module is integrated in the key sending box, the audio power amplifier module has a bidirectional audio function, and can play a received audio signal after being amplified by a power amplifier circuit in the audio power amplifier module, which is equivalent to a sound box which is used as a signal receiving end and simultaneously plays audio. The space is greatly saved, compared with the common KVM seat, the function of audio power amplification (including playing) is added, and the user can directly receive the audio transmitted from the remote end conveniently.
The KVM photoelectric matrix end is connected with each optical moment sending box through optical fibers and receives the audio and video source sent by the optical moment sending box. The optical moment transmitting box can be installed in areas such as a machine room, the outdoor area, each individual room price and a conference room, and the KVM photoelectric matrix end is installed in the main control room to realize man-machine separation. The KVM photoelectric matrix end is also connected with the management end, and the management end is used for controlling the audio and video source of the optical moment sending box to send the audio and video source to the corresponding optical moment receiving box through the KVM photoelectric matrix end. That is, the management terminal is used for switching the link through the KVM optoelectronic matrix terminal to send the audio/video source to the corresponding optical matrix receiving box. For example, the audio/video source end 1 is originally sent to the display 1 where the optical moment receiving box is located, and after the management end sends an instruction to the KVM photoelectric matrix end, the KVM photoelectric matrix end performs link switching, so that the audio/video source of the audio/video source end 1 is sent to the display 2 where the optical moment receiving box is located. Namely, a communication link is established between the optical moment transmitting box where the audio/video source end 1 is located and the optical moment receiving box where the display 2 is located.
The optical moment receiving box is connected with the KVM photoelectric matrix end through optical fibers and used for receiving the audio and video source sent by the KVM photoelectric matrix end.
