Abstract

The utility model discloses a remote image transmitter, which comprises a power supply and a transmitter plate. The transmitter plate is provided with 6 ways of low voltage differential signaling (LVDS) serial output ports, 6 ways of single mode fiber input ports, 6 LVDS level switch chips, 6 photoelectric converters and a field programmable gate array (FPGA) coder decoder. The 6 photoelectric converters respectively obtain image data in a remote computer through the 6 ways of single mode fiber input ports, convert the data into image data in the mode of electric signals and transmit the data to the FPGA coder decoder. The FPGA coder decoder decodes the image data in the mode of the electric signals to obtain the original image data, conducts level conversion through 3 LVDS level switch chips that the LVDS serial output ports correspond to and then transmits the data to an image device simulator to achieve transmission of debugging image data to the image device simulator. The remote image transmitter has the advantages of achieving remote high speed transmission of the debugging image data in the remote computer to the image device simulator and reducing delay of image transmission speed by an electronic device.

Description

A kind of remote image transmitter

Technical field

The utility model relates to a kind of tester, specifically, is a kind of remote image transmitter that is used for the vision facilities simulator.

Background technology

Machine vision equipment is adopted in the current industrial field in a large number; Take photo by plane in the space photography of space industry, the high-altitude of aviation field, the IMAQ of military industry field all needs a large amount of optical imagery equipment; Therefore especially the consecutive image information data amount is big owing to image information, requires real-timely, when transmission, requires very high transmission bandwidth; Number of electronic devices in the middle of will as far as possible reducing, thus transmission speed improved.Therefore, the image transmission has very high performance requirement, and web-transporting device in the past is more suitable for transfer files, can not satisfy the requirement of high-speed transfer image.

Summary of the invention

To the problem that exists in the prior art, it is the long-range transmitter that the debugging image is provided of vision facilities simulator (as: digital camera simulator etc.) that the utility model proposes a kind of convenience, has reduced the delay of electronic equipment to the image transmission speed.

The utility model remote image transmitter comprises power supply, transmitter plate; The transmitter plate has 6 road LVDS serial delivery outlets, 6 road monomode fiber input ports, 6 LVDS level transferring chip, 6 optical-electrical converters and 1 FPGA codec.Power supply links to each other with the transmitter plate.

Wherein, the FPGA codec links to each other with 6 road LVDS serial delivery outlets respectively through 6 LVDS level transferring chip; The FPGA codec also links to each other with 6 road monomode fiber input ports respectively through 6 optical-electrical converters; 6 road monomode fiber input ports link to each other with remote computer.

Said 6 road 3 of LVDS serial delivery outlets are that a component is two groups, and every group of LVDS serial delivery outlet connects a vision facilities simulator; Said every group of LVDS serial delivery outlet exported 1 circuit-switched data signal, 1 road gate-control signal, 1 tunnel clock signal.

Above-mentioned 6 optical-electrical converters link to each other through 6 road monomode fiber input ports respectively and obtain the debugging view data in the remote computer, and the debugging view data that the debugging view data that will obtain converts electrical signal form into sends to the FPGA codec; After the FPGA codec is decoded the debugging view data of electrical signal form; Obtain original debugging view data; And through after 33 corresponding LVDS level transferring chip of LVDS serial delivery outlet are carried out level conversion in every group; Send to the vision facilities simulator by 3 LVDS serial delivery outlets, realize of the transmission of debugging view data thus to the vision facilities simulator.

The advantage of the utility model is:

1, the utility model transmitter makes and realizes remote high-speed transfer between debugging view data and the vision facilities simulator in the remote computer, has reduced the delay of electronic equipment to the image transmission speed;

2, the utility model transmitter is simple in structure, cost is low, and efficiency of transmission is high.

Embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is done further detailed description.

The utility model remote image transmitter comprises power supply 1, transmitter plate 2.Wherein, power supply 1 links to each other with transmitter plate 2, is used for being 2 power supplies of transmitter plate.Said transmitter plate 2 has 203,6 optical-electrical converters 204 of 202,6 the LVDS level transferring chip in 6 road LVDS serial delivery outlets, 201,6 road monomode fiber input ports and 1 FPGA codec 205.

Wherein, each road LVDS serial delivery outlet 201 links to each other with FPGA codec 205 through a LVDS level transferring chip 203, and 6 road 3 of LVDS serial delivery outlets are that a component is two groups, and every group of LVDS serial delivery outlet connects a vision facilities simulator; Every road LVDS serial delivery outlet 201 is through a LVDS level transferring chip 203 outputs one road LVDS signal, therefore 6 road LVDS serial delivery outlets, 201 exportable 6 road LVDS signals.Every group of LVDS serial delivery outlet exported 1 circuit-switched data signal, 1 road gate-control signal (gate), 1 tunnel clock signal (CLK).

Each monomode fiber input port, road 202 links to each other with FPGA codec 205 through an optical-electrical converter 204.6 road monomode fiber input ports 204 all are used for connecting remote computer; Make remote computer transfer to the debugging view data in the optical-electrical converter 204 of each monomode fiber input port 204 connections through 6 road monomode fiber input ports 204 thus; To debug after picture number converts the signal of telecommunication that adopts the Manchester code coding into through optical-electrical converter 204; Send in the FPGA codec 205 and decode, obtain original debugging view data.After original tune-up data carries out level conversion through 3 LVDS level transferring chip 203; 3 road LVDS serial delivery outlets 201 by 3 LVDS level transferring chip 203 therewith link to each other are exported to a vision facilities simulator with 10Mbps speed, realize the transmission of debugging view data to the vision facilities simulator thus.

The utility model is owing to adopt monomode fiber input port 202, makes the debugging image data transmission distance can be greater than 1000 meters thus, and monomode fiber input port, every road 202 bandwidth maximums can reach 20Mbps.
