Isolation.
Further, the transformed parallel image signals of DS92LV3242 are exported to FPGA, and 10 spectral coverage figures are realized by FPGA
As data buffer storage, more spectral coverages are adaptive and Video Out.
In order to realize more spectral coverage adaptation functions, the present invention realizes multispectral image data by the way of being exported by bag
Transmission.Core concept is to establish a kind of video transmission protocol, and agreement regulation, image is exported by bag, and per bag data, composition is：8 words
Save packet header, 4 byte packet sequence numbers, 1 byte detector and spectral coverage mark, 3 byte reserved places and 1K byte image data.Packet header is 8

Mark minute book bag data is exported by which detector and corresponding spectral coverage.Based on such a transport protocol, image need not be by spectrum
Section 1 arrives 10 Sequential output of spectral coverage, without externally input spectral coverage number is considered, only need to judge each image buffer storage module in time
Amount of images whether reach 1K bytes, reach 1K bytes and export.Upper computer software can parse 10 spectral coverages according to agreement
View data.This transmission mode had both solved that input image data amount is larger, the limited problem of FPGA internal RAM resources, again
Realize more spectral coverage adaptation functions.

This chip parallel data clock is up to 66MHz, and maximum rate is up to 528MB/s, Neng Gouman when transmitting data using Full patterns
Pedal system demand.
As shown in Fig. 2, cores of the FPGA as image transmission, is made of 3 modules：Image buffer storage module,
Image packetization module and image output module.The main caching for realizing multispectral image data, image packing and view data
Sending function.
The image buffer storage module realizes the caching function of 10 spectral coverage view data of No. 6 detector, and near-infrared image delays
Storing module realizes the caching of near-infrared (spectral coverage 1) view data, nearly short-wave infrared image buffer storage module realizes nearly shortwave (spectral coverage 2)
The caching of infrared picture data, short-wave infrared image buffer storage module realize the slow of shortwave (spectral coverage 3, spectral coverage 4) infrared picture data

Storing module realizes that the caching of long wave (spectral coverage 7, spectral coverage 8) infrared picture data, myriametric wave infrared image cache module realize overlength
The caching of ripple (spectral coverage 9, spectral coverage 10) infrared picture data.A FIFO (First-In is included inside each cache module
First-Out) storage unit, realizes the caching of image.Each FIFO corresponds to a programmable spacing wave Prog_Empty,
Prog_Empty values are less than 1K bytes for data volume in 1 expression FIFO, and Prog_Empty values are more than for data volume in 0 expression FIFO
Or equal to 1K bytes.The programmable spacing wave of 6 image buffer storage module outputs is respectively Prog_Empty1~Prog_Empty6.
Further, Prog_Empty1~Prog_Empty6 signal outputs of image buffer storage module to image pack mould
Block.Corn module of the image packetization module as FPGA, mainly by state machine, bag sequence number management module, detector and spectrum
Totally 5 parts form for segment mark management module, image data management module, packing output module.
The state machine is the core of image packetization module, and image packing process state transition diagram is as shown in Figure 3.System
After system resets, state machine is waited for, and judges the value of Prog_Empty1~Prog_Empty6 successively in wait state, if
The Prog_Empty signal values for determining a certain image buffer storage module are 0, then state machine jumps to corresponding image packing state,
Otherwise still in wait state cycle criterion.
The bag sequence number management module is responsible for the bag sequence number of each detector, and each detector individually calculates Bao Xu
Number, for example often export a bag near-infrared image data near-infrared bag sequence number and add 1, a bag myriametric wave infrared picture data is often exported,
Myriametric wave bag sequence number adds 1.
Detector and spectral coverage the annotation management module is responsible for the detector and spectral coverage mark of the image currently exported,
Detector and spectral coverage mark lengths are a byte, wherein high 4 represent detector, near infrared detector is represented respectively with 1~6
To overlength wave detector；Low 4 represent spectral coverage, represent near-infrared spectral coverage to myriametric wave spectral coverage respectively with 0~9.
Described image data management module real-time judge state machine state, when state machine is in a certain image packing state
When, image data management module sends to corresponding image buffer storage module and reads fifo signal, from corresponding image buffer storage module
1K byte image data are read in FIFO.
The module that transmits will fix packet header, bag sequence number, detector and spectral coverage mark, view data packing, and raw
Into image frame signal and row signal, the view data after packing, frame signal and row signal are sent to image output module.
Finally, the transmission of view data is realized by image output module.
Simple spectrum section image packing process and bispectrum section image packing process are told about separately below.
Simple spectrum section image packing process is by taking near-infrared image as an example, and when Prog_Empty1 values are 0, state machine jumps to closely
Infrared image packing state, and 1K bytes are read from the FIFO of near-infrared image cache module by image data management module
View data；Add 1 by bag sequence number management module nearly infrared picture data bag sequence number at the same time；Marked by detector and spectral coverage
The detector and spectral coverage mark (1 byte) of management module generation current data packet, are worth for 0x10；Finally will by packing output module
Fixed packet header (8 byte), near-infrared bag sequence number (4 byte), detector and spectral coverage mark (1 byte), reserve (3 byte), be near red
Outer view data (1K bytes) packing, state machine returns to wait state after the completion of packing.
Bispectrum section image packing process is by taking myriametric wave infrared image as an example, as the Prog_Empty of other image buffer storage modules
Value is 1, and when only Prog_Empty6 values are 0, state machine jumps to myriametric wave infrared image packing state, and passes through image
Data management module reads 1K byte image data from the FIFO of myriametric wave infrared image cache module；Pass through bag sequence number at the same time
Myriametric wave infrared picture data bag sequence number is added 1 by management module；Current number is generated by detector and spectral coverage annotation management module
(1 byte) is marked according to the detector and spectral coverage of bag, is worth for 0x68/0x69, it is worth mentioning at this point that, since double-colored (bispectrum section) is infrared
The picture format of TDI detectors output is a line spectral coverage 1, (spectral coverage 1, spectral coverage 2 herein refers to for the circulation of a line spectral coverage 2 output
Spectral coverage inside double-color detector), it is therefore desirable to design counter and realize differentiation to bispectrum section, such as myriametric wave infrared image
Data line amount is exactly 1K bytes, therefore the area of two spectral coverages is achieved that to the row signal-count of myriametric wave infrared image
Point, when row count value is odd number, detector and spectral coverage mark value are 0x68, when row count value is even number, detector and spectrum
Segment mark value is then 0x69.Finally will fixed packet header (8 byte), myriametric wave bag sequence number (4 byte), detection by packing output module
Device and spectral coverage mark (1 byte), reserved (3 byte), myriametric wave infrared picture data (1K bytes) packing, state after the completion of packing
Machine returns to wait state.
