Description
[technical field]
The utility model relates to computer communication complex field, specially a kind of video information acquisition device.
[background technique]
The acquisition and transmission of video information are an important directions of Information Technology Development, traditional video signal collection dress
It sets and needs muti-piece single-chip microcontroller co-ordination, so structure is complicated for traditional video signal acquisition device, volume is larger, vision signal
Efficiency of transmission and transmission quality are low, not convenient enough in actual use.
It can be seen that providing the problem of a kind of improved video signal acquisition device is this field urgent need to resolve.
[utility model content]
The utility model is in view of the above-mentioned problems, provide a kind of video signal acquisition device, by one piece of fpga chip
Instead of several piece single-chip microcontroller, the structure of video signal acquisition device is simplified, improves efficiency of transmission and transmission quality, and can be with
Transmitted in both directions.
To solve the above problems, video signal acquisition device provided by the utility model include fpga chip, with FPGA phase
Sil9232 chip even, the PC machine being connected with Sil9232 chip, key mouse K/M and the Video equipment being connected with fpga chip, institute
Fpga chip and Sil9232 integrated chip are stated on pcb board, is connected between the Video equipment and fpga chip by DVI line
It connects, the vision signal in the PC machine is burnt in Video equipment after Sil9232 chip and fpga chip processing, described
Vision signal in Video equipment is by Sil9232 chip and ARM chip memory into PC machine.
Further, the video signal acquisition device is with one piece of fpga chip and every piece of fpga chip has 6 and connects
Mouthful.
Further, the Sil9232 chip has 2, is connected on two interfaces of fpga chip by integrated circuit.
Further, the PC machine has two, and every PC machine is all connected with one piece of Sil9232 chip.
Further, the fpga chip connects two sets of key mouse K/M and two Video equipment by four interfaces.
Further, the interface that the key mouse K/M is connect with fpga chip is USB2.0 interface.
Further, the interface that the Video equipment is connect with fpga chip is DVI interface.
Furthermore several piece single-chip microcontroller is replaced by one piece of fpga chip, simplifies the structure of video signal acquisition device, is improved
Efficiency of transmission and transmission quality, and can with transmitted in both directions.
[Detailed description of the invention]
Fig. 1 is the composed structure block diagram of the utility model video signal acquisition device.
[specific embodiment]
Referring to Fig. 1, the composed structure of the utility model video signal acquisition device is given comprising one piece of FPGA core
Piece, two pieces of Sil9232 chips, two PC machine, two sets of key mouses, two Video equipment, the fpga chip have 6 interfaces, the
One interface is USB2.0 interface, connects a set of key mouse K/M1 by USB line, second interface is DVI interface, is connected by DVI line
Video equipment 1, third interface are USB2.0 interface, connect a set of key mouse K/M2 by USB line, and the 4th interface is DVI interface,
Video equipment 2 is connected by DVI line, the 5th interface and the 6th interface pass through integrated circuit and two pieces of Sil9232 chips connect
It connects, the Sil9232 chip tool is there are two interface, and first interface is all connected with fpga chip, and second interface passes through client cables
It is separately connected the PC machine 1 and PC machine 2.
Because the video signal acquisition device supports full signal access, signal is between PC machine and Sil9232 chip
Bi-directional, signal are bi-directional between Sil9232 chip and fpga chip, and signal is in fpga chip and Video equipment
Between be bi-directional, so the signal of PC machine can be burnt in Video equipment, the signal in Video equipment can also be stored up
It is stored in PC machine, signal enters Sil9232 chip by client cables by PC machine 1 or PC machine 2, then passes through Sil9232 and FPGA
Integrated circuit between chip, which enters in fpga chip, to be handled, and treated signal passes through DVI line by the DVI interface of fpga chip
Imprinting is carried out into Video equipment 1 or Video equipment 2.Alternatively, signal passes through DVI line by Video equipment 1 or Video equipment 2
Enter fpga chip by DVI interface, signal is after the processing of FGPA chip by between fpga chip and Sil9232 chip
Integrated circuit enter Sil9232 chip, then enter PC machine 1 by client cables or PC machine 2 is stored.Pass through one piece of FPGA
Chip replaces several piece single-chip microcontroller, simplifies the structure of video signal acquisition device, improves efficiency of transmission and transmission quality, and
It can be with transmitted in both directions.
In addition, it should be understood that although this specification is described in terms of embodiments, but not each embodiment is only wrapped
Containing an independent technical solution, this description of the specification is merely for the sake of clarity, and those skilled in the art should
It considers the specification as a whole, the technical solutions in the various embodiments may also be suitably combined, forms those skilled in the art
The other embodiments being understood that.
