Abstract
The invention discloses a system for copying data among multidimensional code separation nets. The system is capable of realizing that two hosts without any physical connection and network connection efficiently communicate through multiple two-dimensional codes, a scanner for multiple two-dimensional codes scans a plurality of two-dimensional codes once, and is capable of scanning the whole display screen once, so that point-to-point reliable transmission is realized. According to the system disclosed by the invention, the problem of system communication among the separation net systems is solved, the security in the communication is ensured; through the multiple two-dimensional codes, the problem of less information content of single coding of the two-dimensional codes is solved so that the integral performance of a communication system is improved and the work efficiency is high.
Description
Technical field
The present invention relates to the compunication security fields, be specifically related to a kind of towards the computer security communication means without any physical connection.
Background technology
Traditional compunication all is based on network communication protocol, by wired or wireless network, connects, and communication security can't definitely guarantee, at some, to communication security, under exigent environment, can't be protected.
Quick Response Code is mainly used in the less sign bar code of amount of information etc. at present, because the amount of information of Quick Response Code single transmission is limited, in also not extensive use of data communication field.
Summary of the invention
The object of the present invention is to provide the communication means connected without any physical connection, network between a kind of computer-oriented, solve traditional Network Communicate Security problem, adopt multiple Quick Response Code to improve efficiency of transmission, can be widely used in the compunication between separation net.
For achieving the above object, the following technical scheme of the concrete employing of the present invention: a kind of based on data copying system between the multidimensional code separation net, comprise the following steps: connect: two main frames are by No. ID and type of message generation Quick Response Code of message header, scan respectively the display of two main frames by scan module, when No. ID of two main frames and type of message coupling, two main frames connect; Send: " message header+message content " is encoded into to Quick Response Code, is presented on display, by scan module, scan the receiving terminal display, wait for that the other side receives the ACK answer signal, receive that the follow-up supervention of answer signal send next message; Receive: scan the transmitting terminal display by scan module, resolve the message received, if message checking is correct, message header ack_no and seq_no are increased to 1, type of message is TYPE_ACK, generates two-dimension code image and is presented on display, waits for that transmitting terminal reads the ACK answer signal.
The inventive method realizes two main frame efficient communication that connect without any physical connection, network by the Quick Response Code scan module, and communication security can be guaranteed.
For improving the Quick Response Code coding information quantity, scan module adopts multiple Quick Response Code to realize, a plurality of Quick Response Codes of multiple Quick Response Code scanner single pass, and single scan range is whole display screen.Full screen scanning, realize point-to-point transmitting; Solve the less problem of Quick Response Code single coding information quantity by multiple Quick Response Code, make the overall performance of communication system be improved.
Advantage of the present invention is: one, adopt multiple Quick Response Code, and improved the efficient work of communication system; Its two, without any physical connection, network, connect, guaranteed communication security.
The accompanying drawing explanation
Fig. 1 is that the present invention isolates the internetwork communication overall schematic.
Embodiment
Below in conjunction with accompanying drawing, technical scheme of the present invention is elaborated:
As shown in Figure 1, the present invention is directed to two computers that connect without any physical connection, network and carry out safe and reliable communication.Whole system comprises host A, B, display, A, B scan module.Job step is as follows:
1, connect: host A, B are by No. ID and type of message generation Quick Response Code of message header, and A end probe scans B display, B end probe scan A end display, if ID and type of message coupling, A, B connect;
2, send: " message header+message content " is encoded into to Quick Response Code, is presented on display, by scan module, scan the receiving terminal display, wait the other side receives and replys (ACK) signal, receives that the follow-up supervention of answer signal send next message;
Receive: scan the transmitting terminal display by scan module, resolve the message received, if message checking is correct, message header ack_no and seq_no are increased to 1, type of message is TYPE_ACK, generates two-dimension code image and is presented on display, waits for that transmitting terminal reads the ACK answer signal.
Claims (2)
1. one kind based on data copying system between the multidimensional code separation net, it is characterized in that, comprises the following steps:
Connect: two main frames by message header No. ID and type of message generate Quick Response Code, by scan module, scan respectively two Quick Response Codes on host display, and when No. ID of two main frames and type of message coupling, two main frames connect;
Send: " message header+message content " is encoded into to Quick Response Code, is presented on display, by scan module, scan the receiving terminal display, wait for that the other side receives the ACK answer signal, receive that the follow-up supervention of answer signal send next message;
Receive: scan the transmitting terminal display by scan module, resolve the message received, if message checking is correct, message header ack_no and seq_no are increased to 1, type of message is TYPE_ACK, generates two-dimension code image and is presented on display, waits for that transmitting terminal reads the ACK answer signal.
2. data copying system between a kind of multidimensional code separation net according to claim 1, it is characterized in that connecting without any physical connection, network, scan module adopts multiple Quick Response Code to realize, a plurality of Quick Response Codes of multiple Quick Response Code scanner single pass, and single scan range is whole display screen.
