The following describes in detail a specific flow of each step of the data communication method of the present embodiment.
In step S201, the communication terminal captures the mobile feature code through the first camera at a first set time interval to obtain the mobile terminal information.
The mobile feature code is generated by the mobile terminal, and feature code information is displayed through a mobile feature code display screen of the mobile terminal, wherein the mobile feature code can be a bar code, a two-dimensional code, a graphic code and other feature codes. The mobile signature includes mobile terminal information that the mobile terminal wants to send to the communication terminal.
The first set time interval is set according to the requirement of a user, and is generally set to be within 1 second so as to rapidly acquire the mobile terminal information of the mobile terminal.
Specifically, if the communication terminal captures a plurality of mobile feature codes (e.g., the communication terminal captures mobile feature codes of a plurality of mobile terminals) through the first camera, the plurality of mobile feature codes are all set as the preliminary mobile feature codes, and the position of the current preliminary mobile feature code is obtained.
Then the communication terminal calculates the position distance value between the position of all the current prepared mobile characteristic codes and the position of the previous mobile characteristic code, and sets the current prepared mobile characteristic code with the minimum position distance value as the current mobile characteristic code. If a plurality of current prepared moving feature codes with the same position distance value exist, the setting operation of the current moving feature codes can be repeated after a set time period, or an error is directly prompted.
Specifically, in order to further improve the security of the obtained mobile terminal information, the location of the current mobile feature code is also identified, specifically referring to fig. 3, fig. 3 is a flowchart of step S201 of the second embodiment of the data communication method according to the present invention. The step S201 includes:
step S301, in the same data communication process, the communication terminal acquires the position of the current mobile feature code in the mobile feature code display screen so as to carry out security identification on the current mobile feature code.
Step S302, the communication terminal judges whether the position of the current mobile feature code and the position of the previous mobile feature code are larger than a set distance value, if so, the communication terminal goes to step S303; if the distance is less than or equal to the set distance value, the process proceeds to step S202.
Step S303, if the position of the current mobile feature code and the position of the previous mobile feature code are greater than the set distance value, it indicates that the current mobile feature code and the previous mobile feature code may belong to different mobile terminals, and in order to improve the identification security of the current mobile feature code, the communication terminal does not respond to the mobile terminal information corresponding to the current mobile feature code or prompts an error.
In step S202, if the position of the current mobile feature code and the position of the previous mobile feature code are less than or equal to the set distance value, the communication terminal obtains the current mobile terminal information corresponding to the current mobile feature code.
And then the communication terminal judges whether the current mobile terminal information is associated with the current communication terminal information or not so as to judge whether the corresponding communication terminal information can be generated through the current mobile terminal information or not. If the current mobile terminal information is associated with the current communication terminal information, go to step S205; if the current mobile terminal information is not associated with the current communication terminal information, the process goes to step S203.
In step S203, the communication terminal determines whether the current mobile terminal information is mobile terminal communication start information; the mobile terminal communication start information is information that the mobile terminal requests to start information interaction operation with the communication terminal. If the current mobile terminal information is not the mobile terminal communication start information, go to step S204; if the current mobile terminal information is the mobile terminal communication start information, go to step S205.
In step S204, since the current mobile terminal information is not the mobile terminal communication start information, and the current mobile terminal information is not associated with the current communication terminal information, the communication terminal cannot perform subsequent information interaction operations with the mobile terminal according to the current mobile terminal information, and therefore the communication terminal does not respond to the current mobile terminal information or prompts an error. If the current mobile terminal information contains a unique mobile terminal code, such as a unique hardware code, the information interaction operation between a plurality of mobile terminals and the communication terminal can be effectively prevented by a user.
In step S205, if the current mobile terminal information is the mobile terminal communication start information, the communication terminal generates corresponding communication terminal information according to the mobile terminal information acquired in step S201. The communication terminal information is information indicating a result of processing of the mobile terminal information by the communication terminal. If the mobile terminal information is payment information, the communication terminal information may be payment confirmation information or the like, and the payment confirmation information may be generated by the communication terminal through a background server or generated by the communication terminal according to a built-in database of the communication terminal.
If the communication terminal information is generated through the background server, the communication terminal can send the mobile terminal information to the background server, so that the background server can generate corresponding mobile terminal response information according to the background data of the background server. And then the communication terminal receives the mobile terminal response information from the background server and generates corresponding communication terminal information according to the mobile terminal response information.
If the communication terminal information is generated through the built-in database of the communication terminal, the communication terminal directly generates the corresponding communication terminal information according to the built-in database.
In this step, the communication terminal information may be generated by local data of the communication terminal or by external server data, and thus the interaction between the communication terminal and the mobile terminal may be performed on-line or off-line.
In step S206, the communication terminal performs an encoding operation on the communication terminal information generated in step S205, generates a corresponding communication feature code, and displays the communication feature code on a communication feature code display screen of the communication terminal.
The communication feature code is feature code information generated by the communication terminal and displayed through a communication feature code display screen of the communication terminal, and the communication feature code can be a bar code, a two-dimensional code, a graphic code and other feature codes. The communication feature code includes communication terminal information that the communication terminal wants to transmit to the mobile terminal.
And the mobile terminal acquires the communication terminal information through the second camera and generates a corresponding mobile feature code according to the communication terminal information. Referring to fig. 4, fig. 4 is a flowchart illustrating a mobile terminal generating a mobile feature code according to a second embodiment of a data communication method of the present invention. The process of generating the mobile feature code by the mobile terminal comprises the following steps:
step S401, the mobile terminal shoots the communication feature code through the second camera at a second set time interval to obtain the communication terminal information.
The communication feature code is generated by the communication terminal, and feature code information is displayed through a communication feature code display screen of the communication terminal, wherein the communication feature code can be a bar code, a two-dimensional code, a graphic code and other feature codes. The communication feature code includes communication terminal information that the communication terminal wants to transmit to the mobile terminal.
The second setting time interval is set according to the requirement of the user, and is generally set to be within 1 second so as to rapidly acquire the communication terminal information of the communication terminal.
Step S402, the mobile terminal generates corresponding mobile terminal information according to the communication terminal information acquired in step S401. The mobile terminal information is information indicating a result of processing of the communication terminal information by the mobile terminal. If the communication terminal information is payment confirmation information, the mobile terminal information may be confirmation feedback information or the like, and the confirmation feedback information may be generated by the mobile terminal through a background server or generated by the mobile terminal according to a built-in database of the mobile terminal.
If the mobile terminal information is generated through the background server, the mobile terminal can send the communication terminal information to the background server, so that the background server can generate corresponding communication terminal response information according to the background data of the background server. And then the mobile terminal receives the communication terminal response information from the background server and generates corresponding mobile terminal information according to the communication terminal response information.
If the mobile terminal information is generated through the built-in database of the mobile terminal, the mobile terminal directly generates the corresponding mobile terminal information according to the built-in database.
In this step, the mobile terminal information may be generated by local data of the mobile terminal or by external server data, so that the interaction between the communication terminal and the mobile terminal may be performed online or offline.
In step S403, the mobile terminal performs an encoding operation on the mobile terminal information generated in step S402, generates a corresponding mobile feature code, and displays the mobile feature code on a mobile feature code display screen of the mobile terminal.
The mobile feature code is generated by the mobile terminal, and feature code information is displayed through a mobile feature code display screen of the mobile terminal, wherein the mobile feature code can be a bar code, a two-dimensional code, a graphic code and other feature codes. The mobile signature includes mobile terminal information that the mobile terminal wants to send to the communication terminal.
Thus, the process of generating the mobile feature code by the mobile terminal is completed, and the step S401 may be returned to continue the next information interaction operation until the communication terminal generates the communication terminal information of which the communication is finished, that is, the information interaction operation is finished at the communication terminal; or the communication terminal generates and displays the communication feature code corresponding to the communication terminal information of which the communication is finished, namely the mobile terminal finishes the information interactive operation according to the communication terminal information corresponding to the communication feature code.
This completes the data communication process between the communication terminal and the mobile terminal of the data communication method of the present embodiment.
On the basis of the first embodiment, the data communication method of this embodiment performs security identification on the current mobile terminal information based on the position of the current mobile feature code and the relevance between the current mobile terminal information and the current communication terminal information, thereby further improving the security of the interactive operation between the communication terminal and the mobile terminal.

The mobile signature includes mobile terminal information that the mobile terminal wants to send to the communication terminal.
The first set time interval is set according to the requirement of a user, and is generally set to be within 1 second so as to rapidly acquire the mobile terminal information of the mobile terminal.
Then, the communication terminal information generating module 52 generates corresponding communication terminal information according to the mobile terminal information acquired by the mobile terminal information acquiring module 51. The communication terminal information is information indicating a result of processing of the mobile terminal information by the communication terminal. If the mobile terminal information is payment information, the communication terminal information may be payment confirmation information or the like, and the payment confirmation information may be generated by the communication terminal through a background server or generated by the communication terminal according to a built-in database of the communication terminal.
Finally, the communication feature code display module 53 performs an encoding operation on the communication terminal information generated by the communication terminal information generation module 52 to generate a corresponding communication feature code, and displays the communication feature code on a communication feature code display screen of the communication terminal.
The communication feature code is generated by the communication terminal, and feature code information is displayed through a mobile feature code display screen of the mobile terminal, wherein the mobile feature code can be a bar code, a two-dimensional code, a graphic code and other feature codes. The mobile signature includes communication terminal information that the communication terminal wants to send to the mobile terminal.
And the mobile terminal acquires the communication terminal information through the second camera and generates a corresponding mobile feature code according to the communication terminal information. Thus, one information interaction operation between the communication terminal and the mobile terminal is completed, and the information interaction operation can be returned to the mobile terminal information acquisition module to continue the next information interaction operation until the communication terminal generates communication terminal information with the communication finished, namely the information interaction operation is finished at the communication terminal; or the communication terminal generates and displays the communication feature code corresponding to the communication terminal information of which the communication is finished, namely the mobile terminal finishes the information interactive operation according to the communication terminal information corresponding to the communication feature code.

in step S701, the user controls the smart phone 61, so that the feature code display 612 of the smart phone 61 displays a corresponding mobile feature code (e.g., a two-dimensional code for applying a fee deduction).
Step S702, the user places the smartphone 61 in front of the feature code scanning device 62, and the feature code scanning device 62 photographs the mobile feature code on the smartphone 61 through the device camera 621 at a time interval of 0.5S, so as to obtain corresponding information of the fee deduction account.
In step S703, the feature code scanning device 62 generates corresponding fee deduction information according to the fee deduction account information.
When the feature code scanning device 62 is in a networking state, the feature code scanning device 62 may send the information of the fee deduction account to the background server, complete the fee deduction operation, and generate corresponding fee deduction information.
When the feature code scanning device 62 is not in the networking state, the feature code scanning device 62 directly generates corresponding fee deduction information according to the built-in database.
In step S704, the feature code scanning device 62 encodes the deduction information to generate a corresponding communication feature code, and displays the communication feature code on the feature code display screen 622. The smartphone 61 obtains the communication feature code through the mobile terminal camera 611, and obtains corresponding fee deduction information through a corresponding decoding operation.
Therefore, the smart phone 61 can confirm the deduction condition through the information sent by the background server, and can also confirm the deduction condition through the deduction information fed back by the feature code scanning device 62, so that the smart phone 61 can also complete the deduction operation in a non-networking state.
In step S705, the smartphone 61 may generate corresponding fee deduction confirmation information according to the fee deduction information, and display the mobile feature code corresponding to the fee deduction confirmation information by using the feature code display screen 612.
In step S706, the feature code scanning device 62 captures the mobile feature code on the smartphone 61 through the device camera 621, so as to obtain the corresponding fee deduction confirmation information.
In step S707, after the feature code scanning device 62 receives the deduction confirmation information, the information interaction operation is ended.
In this embodiment, the smart phone 61 and the feature code scanning device 62 interact with each other through feature codes for multiple times, so that the security of feature code interaction and the amount of information that can be interacted are greatly improved. In this embodiment, a process of key interaction between the smart phone 61 and the feature code scanning device 62 through the feature code may be further set before step S701, so that the security of information interaction between the smart phone 61 and the feature code scanning device 62 may be further improved.
In order to further improve the security of information interaction, the feature code scanning device 62 may further include an outer shell 63, the device camera 621 and the feature code display screen 622 are both disposed in the outer shell 63, and a feature code collecting window 631 is disposed on the outer shell 63, so that the device camera 621 of the feature code scanning device 62 can shoot the smart phone 61 to display the two-dimensional code.
Fig. 8 is a schematic structural diagram of a data communication device according to an embodiment of the present invention. When the feature code scanning device 60 of the embodiment is used, the smart phone 61 can be placed at the feature code collecting window 631, so that the device camera 621 of the feature code scanning device 62 can shoot the mobile terminal display screen 612 of the smart phone 61 through the feature code collecting window 631. Specifically, a mobile terminal placing position 632 may be set at the feature code collecting window 631, so that the user may directly place the smart phone 61 on the mobile terminal placing position 632, thereby avoiding inaccuracy of the placing position of the smart phone 61. When the smartphone 61 is placed in the feature code collecting window 631, the mobile terminal camera 611 of the smartphone 61 can shoot the feature code display screen 622 of the feature code scanning device 62, the device camera 621 of the feature code scanning device 62 can shoot the mobile terminal display screen 612 of the smartphone 61, and multiple times of information interaction can be performed between the smartphone and the feature code scanning device 62.
The data communication method and the data communication device realize the data communication between the communication terminal and the mobile terminal based on the feature code (such as the two-dimensional code), and can effectively improve the convenience and the safety of the interactive operation between the communication terminal and the mobile terminal; the technical problems that the existing data communication method and the existing data communication device are poor in convenience and safety in interactive operation are effectively solved.
