There is other embodiment, shall fall within the protection scope of the present invention.
In view of in the related technology by manually replicating information to be transmitted to hard disk from outer net, then from copying letter to be transmitted
Intranet is ceased, efficiency is very low, cannot be satisfied the requirement of real-time service.Based on this, an embodiment of the present invention provides a kind of outer nets
Method, interior network termination and the outer network termination that information is transmitted to Intranet, are described below by embodiment.
Embodiment 1
An embodiment of the present invention provides a kind of methods that outer net transmits information to Intranet.In order to ensure the safety of Intranet information
Property, physical isolation has been carried out to Intranet and outer net, if outer network termination needs inside network termination to transmit information in this context, has been used
Method provided in an embodiment of the present invention can realize that the automatic information between outer network termination and interior network termination transmits, and avoid information
Manual intervention in transmission process, improves information transfer efficiency, and the real-time of information transmission is very strong.
Referring to Fig. 1, this method specifically includes following steps：
Step 101：Information to be transmitted is converted to character text data by outer network termination by preset custom protocol.
Above-mentioned preset custom protocol and existing all puppy parcs are different.By preset custom protocol come
Provide the format of information to be transmitted.For example, providing the content of information to be transmitted by digital group by preset custom protocol
At, number between only distinguished with limited several list separators such as comma, exclamation.It can effectively prevent institute by custom protocol
There is traditional network attack, and by making user-defined format that there is the feature of versatility and simplicity, can be effectively reduced to be passed
Defeated information is tampered to influence caused by intranet security.In embodiments of the present invention, it can be updated with every preset time period pre-
If custom protocol, that improves custom protocol cracks difficulty, further increase information transmission safety.
When outer network termination needs inside network termination to transmit information, outer network termination is according to preset custom protocol to be passed
Defeated information carries out limited character set text code.Each character that information to be transmitted is included by i.e. outer network termination is with preset
Number as defined in custom protocol is indicated, and is represented between the numeric string of kinds of characters as defined in preset custom protocol
Separator separates, to which information to be transmitted is converted to character text data.
Since the transport layer information content of outer network termination uses text encoding format, advised by preset custom protocol
It is fixed only to select partial character set, such as there was only number and limited several decollators.It so further decreases hacker and utilizes the information content
Distort so that control system possibility.
Step 102：Outer network termination obtains the corresponding all frame blocks of information to be transmitted according to character text data.
Character text data is split as multiple text data packets by outer network termination；According to preset image coding and decoding pattern,
Multiple text data packets are encoded respectively, obtain the corresponding all frame blocks of information to be transmitted.Wherein, preset figure
As including check code in the corresponding coding rule of encoding/decoding mode.It can be Quick Response Code or bar shaped to encode obtained frame block
Code etc..
In embodiments of the present invention, the number that the text data packet split out can be arranged in outer network termination in advance is pre-
If number.For any information to be transmitted, when outer network termination splits information to be transmitted corresponding character text data, by character
Text data is split as preset number text data packet.For example, setting preset number is 5, then institute's available for transmission information corresponds to
Character text data be all split as 5 text data packets.In addition to being split as preset number to the mode of text data packet, may be used also
Size each text data packet split out is arranged in outer network termination in advance is default size.For any letter to be transmitted
Breath, outer network termination calculate the ratio of the data volume and default size of the corresponding character text data of information to be transmitted, will be to be transmitted
The corresponding character text data of information is divided into the ratio text data packet.For example, it is 5KB that size is preset in setting, if to be passed
The data volume of the corresponding character text data of defeated information is 25KB, then the character text data is split as 5 5KB by outer network termination
The text data packet of size.
After character text data is split as multiple text data packets in the manner described above, according to preset image coding and decoding
Each text data packet encoder is respectively image by pattern.Preset image coding and decoding pattern can be two-colour diagram as pattern, such as
Black-and-white two color image model or red blue dichromatism image model etc..In embodiments of the present invention, pass through preset custom protocol
Only include number and limited several separators after information to be transmitted is converted to character text data, in character text data.If
Number as defined in preset custom protocol only includes 0 and 1 two number, then directly carries out image volume by dichromatism image model
Code, represents 0 with a kind of color, 1 is represented with another color.For example, it is assumed that number as defined in preset custom protocol is 0 He
1, dichromatism image model is black-and-white two color image model, then white represents 0, and black represents 1.If preset custom protocol regulation
Number be not 0 and 1 or it is defined number include more than two numbers, such as 0,1 and 2 etc..Then to text data packet into
Before row image coding, text binary coding also is carried out to text data packet, the number in text data packet is all converted to
Binary system, so that only including 0 and 1 two kind of number in text data packet.Then again by dichromatism image model to textual data
Image coding is carried out according to packet.
Step 103：The corresponding all frame blocks of information to be transmitted are displayed on the screen by outer network termination.
Outer network termination obtains letter to be transmitted by carrying out image coding to the corresponding each text data packet of information to be transmitted
Cease corresponding all frame blocks, then by following manner by the corresponding all frame blocks of information to be transmitted include
On screen, including：
Outer network termination is divided into multiple display areas according to predeterminable area division information, by screen；When the number of display area
When mesh is equal to the number of the corresponding frame block of information to be transmitted, successively by the corresponding each frame block of information to be transmitted
It is shown in this multiple display area；When the number of display area is more than or less than the corresponding frame block of information to be transmitted
Include in this multiple display area according to display rule is recycled by the corresponding each frame block of information to be transmitted when number
It is interior.
Above-mentioned predeterminable area division information defines the size of the display area marked off.Outer network termination is according to predeterminable area
Screen is divided into multiple display areas by size as defined in division information.Above-mentioned cycle display rule is according to frame block
Sequencing, it is corresponding all according to certain carousel cycle cycle carousel information to be transmitted in display area on the screen
Frame block.I.e. every the corresponding predetermined time interval of carousel cycle, a screen is played according to the sequencing of frame block,
What one screen can not be placed, interior around adjacent carousel, multi-screen plays successively.When playing a screen, frame block can be with tiling
Form arrangement on the screen.The sequencing of frame block is the corresponding text data packet of frame block in original word
Accord with the sequence in text data.
When the number of display area is more than the number of frame block, first according to the sequencing of frame block by institute
There is frame block to be arranged in order in the number display area for being shown in frame block, for remaining display area, then
It is arranged in order display from first frame BOB(beginning of block), if the number of remaining display area is less than the number of frame block
Mesh after being then spaced preset duration, since first display area of screen, connects the last one frame that a screen is shown
Block shows subsequent frame block successively.When the number of display area is less than the number of frame block, first according to information
The sequencing of image block shows the number frame block of preceding display area on the screen successively, is spaced after preset duration again
Remaining frame block is shown on the screen, so recycles all frame blocks of carousel according at interval of preset duration.
For the ease of understanding that outer network termination shows the mode of the corresponding all frame blocks of information to be transmitted, with reference to
Attached drawing illustrates.For example, it is assumed that the screen of outer network termination is divided into 4 display areas.As shown in Fig. 2, information pair to be transmitted
The number for the frame block answered is equal with the number of display area.The corresponding frame block of information to be transmitted be image 1,2,
3 and 4, then by image 1,2,3 and 4 include successively in this 4 display areas.As shown in figure 3, the corresponding information of information to be transmitted
The number of image block is less than the number of display area.The corresponding frame block of information to be transmitted is image 1,2 and 3, then 4 it is aobvious
Show that it is image 1,2,3 and 1 to be shown successively in region, it is assumed that preset duration is 2 seconds, then after being spaced 2 seconds, in 4 display areas
The image of display becomes image 2,3,1 and 2.As shown in figure 4, the number of the corresponding frame block of information to be transmitted is more than display
The number in region.The corresponding frame block of information to be transmitted is image 1,2,3,4 and 5, then starts what 4 display areas were shown
Image is image 1,2,3 and 4, and for interval preset duration after 2 seconds, the image that 4 display areas are shown becomes image 5,1,2 and 3.
The operation of outer network termination 101-103 through the above steps shows the corresponding all frame blocks of information to be transmitted
After on the screen, interior network termination can get information to be transmitted with the operation of 104-106 as follows, realize that outer net is whole
Hold inside network termination transmission information.
Step 104：Interior network termination shoots the screen of outer network termination by image capture device, obtains information to be transmitted and corresponds to
All frame blocks.
In embodiments of the present invention, in order to be further reduced the manual intervention composition in message transmitting procedure, at outer net end
When the corresponding all frame blocks of information to be transmitted are displayed on the screen by end, indicator light can be lighted on the screen, to refer to
Show that current carousel cycle arrives.When the corresponding image capture device of Intranet terminal monitors that the indicator light on outer network termination is lit
When, the screen that interior network termination shoots outer network termination by the image capture device is triggered, the whole screen picture of outer network termination is obtained.
Interior network termination is split as multiple frame blocks according to preset partition information, by whole screen picture.
Since outer network termination by the corresponding text data packet encoder of information to be transmitted before being frame block, to text
Data packet has carried out Binary Text coding, so the corresponding frame block of information to be transmitted is binary message flow graph
Picture.Include check code, the corresponding letter of institute's available for transmission information in coding rule and when being image by text data packet encoder
Breath image block is the binary message stream picture for meeting verification rule.Therefore network termination splits into the whole screen picture of shooting in
After multiple frame blocks, it is first determined whether each frame block is the binary message flow graph for meeting verification rule
Picture.I.e. interior network termination determines whether the first image block is binary message stream picture, and the first image block is multiple frame blocks
In any information image block；If it is, the first image block is added in the corresponding image pond of information to be transmitted；If
It is no, then the first image block is abandoned, first after current carousel cycle carousel cycle is set when arriving again through Image Acquisition
The standby screen for shooting outer network termination, obtains the first image block, until including letter to be transmitted in the corresponding image pond of information to be transmitted
Cease corresponding all frame blocks.Wherein, the preset partition information configured in interior network termination is matched with outer network termination
The preset partition information set is identical.
Since outer network termination takes the mode of cycle carousel to show the corresponding all frame blocks of information to be transmitted, institute
Within network termination shoot whole screen picture in there may be repeat frame block.Therefore when interior network termination determines the first figure
As block is when meeting the binary message stream picture of verification rule, also traverse that the corresponding image pond of information to be transmitted includes is all
Frame block determines in image pond whether included the first image block；If it is, abandoning the first image block；If it is not, then
First image block is added in the corresponding image pond of information to be transmitted by execution.
In embodiments of the present invention, interior network termination gets the corresponding each letter of information to be transmitted by way of this step
After ceasing image block, error checking and correction is carried out to the content of each frame block also according to error correction coding principles.I.e. interior network termination obtains
The corresponding check bit of each frame block is taken, determines whether frame block goes out according to the corresponding check bit of frame block
Mistake, if it is, the screen of outer network termination is shot again through image capture device, it is corresponding until getting information to be transmitted
It is all correct frame blocks.
Step 105：Interior network termination obtains the corresponding character text data of information to be transmitted according to all frame blocks.
After interior network termination gets the corresponding all frame blocks of information to be transmitted, according to preset image coding and decoding mould
Formula, respectively each frame block in the block to all frames be decoded, obtain the corresponding text of each frame block
Notebook data packet；The corresponding text data package of each frame block is combined into character text data.
The preset image coding and decoding pattern configured in interior network termination and the image coding and decoding pattern configured in outer network termination
It is identical.When preset image coding and decoding pattern is dichromatism image model, interior network termination is according to dichromatism image model, by hum pattern
As the color of each pixel in block is converted to corresponding number.For example, preset image coding and decoding pattern is black-and-white two color figure
As pattern, white represents 0, and black represents 1, then pixel white in frame block is labeled as 0, by the pixel of black
Labeled as 1, frame block is so decoded as text data packet.It is not due to working as number as defined in preset custom protocol
0 and 1 or defined digital comprising more than two numbers, whens being waited such as 0,1 and 2, outer network termination is obtaining file pair to be transmitted
When the text data packet answered, Binary Text coding also is carried out to text data packet, therefore Intranet decoding terminals obtain text
After data packet, however, it is determined that number as defined in preset custom protocol is not that 0 and 1 or defined number include two or more
Number, then to text data packet carry out Binary Text coding inversely processing process.
Since preset custom protocol defines the character that can be protected in text data packet, so through the above way
After obtaining the corresponding text data packet of information to be transmitted, interior network termination also determines that these text data packets are in the following way
It is no to be tampered, it specifically includes：
Interior network termination determines whether the character in the first text data packet is character as defined in preset custom protocol,
First text data packet is any text data packet in the corresponding text data packet of each frame block；If it is not, then table
There is the possibility being tampered in the content in bright first text data packet, the first text data packet is abandoned, after current carousel cycle
First carousel cycle arrive when, re-shoot outer network termination screen obtain the first text data packet, until determine again
Character in the first text data packet obtained is character as defined in preset custom protocol；When each frame of determination
When character in the corresponding text data packet of block is character as defined in preset custom protocol, by each frame block pair
The text data packet answered is combined as character text data according to sequencing.
Step 106：Interior network termination parses character text data by preset custom protocol, obtains to be transmitted
Information.
After interior network termination obtains character text data, character text data is resolved to according to preset custom protocol and is waited for
Transmit information.
For the ease of further understanding method provided in an embodiment of the present invention, illustrate below in conjunction with the accompanying drawings.Such as Fig. 5 institutes
Show, outer net terminal-pair information to be transmitted carries out limited character set text code, character text data is obtained, then by character text
Data split into multiple text data packets：Text data packet 1,2 and 3.Image coding is carried out to text data packet 1,2 and 3 respectively,
Obtain the corresponding frame block of information to be transmitted：Image 1,2 and 3.Then whole screen carousel is carried out to image 1,2 and 3, carousel is suitable
Sequence is image 1,2,3 and 1.The whole screen picture of the outer network termination of Intranet terminal taking, multiple information are split as by whole screen picture
Image block：Image 1,2,3 and 1.The image 1,2,3 and 1 that Intranet terminal-pair is split out is identified parsing and obtains text data packet
1,2 and 3, text data packet 1,2 and 3 is merged into character text data, limited character set then is carried out to character text data
Text decoded back obtains information to be transmitted.
In embodiments of the present invention, communication transmission passage is set up between Intranet and outer net using optical transport mode, outside
On the screen by presentation of information to be transmitted, interior network termination is read by image capture device and is shown on outer net terminal screen network termination
Information to be transmitted, to reach transmission of the information from outer net to Intranet.The embodiment of the present invention uses one-way transmission principle, entirely
System only transmits information from outer net to Intranet.Intranet does not allow to transmit information to outer net, is effectively prevented control/feedback closed loop
It is formed, prevents hacker from controlling Intranet by this channel and the information of Intranet is sent to outer net.And it is reliable to improve transmission
Property, the screen of outer network termination is divided into multiple display areas, one group of binary message stream picture of each display area individual transmission.
Interior network termination is according to scheduled region, the binary message stream picture in each region of independent parsing.It in this way will not be because of a small block diagram
As parsing failure, and the transmission of screenful information is caused to fail.And the screen of outer network termination is by taking all small images shielding
The wheel broadcast mode of tiling, all frame blocks of loop play are arranged in order on curtain；Interior network termination finds current information image block
