During use, video input interface on sending module, audio input interface, the first USB interface, computer host power supply switch interface are connected with the corresponding interface of host computer, power input interface is connected with DC power source adapter, and the vision signal of host computer, control signal, usb signal deliver to the 2nd RJ45 interface of receiver module after sending module process through a RJ45 interface, extended line together with DC power supply; 2nd RJ45 interface of receiver module delivers to the interfaces such as video output interface, audio output interface, microphone interface, secondary USB interface, switching on and shutting down interface for user after vision signal, control signal, usb signal and power supply after receiver module process, power supply is wherein after receiver module process, be divided into two-way, one tunnel is for receiver module, and another road is delivered to display power supply interface and connected display for user.Because switching on and shutting down interface leads directly to sending module by the 2nd RJ45 interface, when user shuts down, off signal is directly delivered to sending module and is delivered to host computer by sending module, close host computer, cut off the power channel of a RJ45 interface simultaneously, receiver module power-off, user display is power-off also, can electrical energy saving consumption; When user starts shooting, starting-up signal also directly delivers to sending module, carries out boot action, and user side realizes passive cold boot.
The technical program adopts the twisted-pair feeder of 8 cores to connect sending module and receiver module as extended line, can to user side transmission video signal, control signal and usb signal, can also power to the display of user side and receiver module, the display of user side and receiver module do not need other power supply, not only convenient management, also saves expense.
The beneficial effects of the utility model are: adopt a twisted pair line connection sending module and receiver module, can provide power supply to user side display and receiver module, user side energy power-off completely during shutdown, saves energy.
Accompanying drawing explanation
Fig. 1 is the utility model host computer extension fixture structural representation.
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 range of the present utility model.
As shown in Figure 1, the host computer extension fixture of the present embodiment, comprise sending module 1, receiver module 2 and connect the extended line 3 of sending module 1, receiver module 2, described sending module 1 is provided with video input interface 4, audio input interface 5, first USB interface 6, computer host power supply switch interface 7 for being connected with host computer; Described receiver module 2 is provided with video output interface 8, audio output interface 9, microphone interface 10, secondary USB interface 11, switching on and shutting down interface 12; It is characterized in that: described sending module 1 is also provided with power input interface 13 and the RJ45 interface 14 for transmission video signal, control signal, usb signal and power supply; Described receiver module 2 is also provided with display power supply interface 15 and the 2nd RJ45 interface 16 for receiving video signals, control signal, usb signal and power supply; Described switching on and shutting down interface 12 is connected with the 2nd RJ45 interface 16; A described RJ45 interface 14 is connected with the 2nd RJ45 interface 16 by extended line 3.
