Abstract
Disclosed in the invention is a dynamic bar code-based data exchange method. A data encoding module, a service logic module, and a data decoding module and the like are arranged. According to the invention, on the basis of an encoding parameter, set by a user, of a dynamic bar code as well as a user data type and a data size, the user data are segmented and encoded and then the processed data are written in all frames of the dynamic bar code; a receiving data terminal device scans all frame images of the dynamic bar code, parses data of each frame of the dynamic bar code, and restores the data into original data according to a frame order. Because data exchanging is carried out based on the dynamic bar code, the simple and rapid capacity-extensible data exchange mode and service can be provided for the user.
Description
Technical field
The present invention relates to mobile terminal, barcode technology field, refers to a kind of method for interchanging data based on dynamic bar codes especially.
Background technology
Along with the development of mobile terminal technology and barcode technology, the particularly development of terminal shooting and scan capability, for providing feasibility based on a kind of method for interchanging data based on dynamic bar codes.
The common mode of current traditional internet data exchanged form is for setting up the webserver, for user assignment authority is downloaded, occupation mode is comparatively loaded down with trivial details, it need to be user assignment authority, maybe need to know the better address of resource, need user to input tediously long network address, meanwhile, and the automatic exchange of unrealized data end to end.
And traditional bar coding mode exchanges data can only adapt to the exchanges data with low capacity, barcode data capacity is little, as can encode the at most character of about 4K of QR code, and the increase along with code character, the figure of bar code will more and more be difficult to identification and differentiate, the light to environment for use, and the requirement of scan camera shooting head is more and more higher, limited the application of the exchanges data of larger capacity, and dynamic electron bar code provides the feasibility of the exchanges data of larger capacity for the data exchange ways based on bar code.
Development along with wireless Internet, the scope of terminal is extended to mobile phone, the various portable equipments such as panel computer, the exchanges data of equipment room becomes normality, common exchanges data is except traditional internet data exchanged form, based on various short-distance wireless technology, be also the conventional means of exchanges data, as the exchanges data of wireless blue tooth technology, but there is the otherness of software and hardware and user's the use habit of terminal, and the problem of the fail safe of short-distance wireless technology, make the user of exchanges data of the wireless technology of short distance experience poor, so far also well applied.
Simultaneously, support the terminal of short-distance wireless technology due to the reason of technology maturity and cost, so far also do not obtain large area universal, cannot and not support in support short-distance wireless technology to transmit and swap data between short-distance wireless technology is as the terminal of NFC technology, user's use impression further declines.
And the identification of bar code has become the ability generally possessing of current intelligent terminal, by bar code, realize the exchange of data, to terminal require low, do not need the support of various short-distance wireless technology can realize exchanges data fast, further, the dynamic strip-shaped code carrying by electronic image, has further expanded the ability of the exchanges data based on bar code, can carry fast more data, expand the scene that barcode data exchange is used.
Bar code is as an increasingly mature RM, in various application, obtained well universal, bar code miscellaneous can be used under different scenes, recognition speed and code capacity have all obtained good checking, terminal is to the support of bar code and very universal, by the exchange of bar code trigger data, become a kind of selection of automation data exchanged form.
In view of this, the object of the invention is to propose a kind of method for interchanging data based on cloud memory technology and barcode technology.
?
Summary of the invention

In an embodiment of a kind of method for interchanging data based on dynamic bar codes provided by the invention, the method also comprises:
System according to the data redudancy partition data of the amount of capacity of every frame and barcode space, and is converted to after character text according to the coding rule of dynamic bar codes the component frame to each dynamic bar codes by data encoding by the data after cutting apart by modes such as BASE64 by data.
In an embodiment of a kind of method for interchanging data based on dynamic bar codes provided by the invention, the method also comprises:
Other-end is opened the dynamic bar codes on camera scanning user mobile phone, catch each two field picture on dynamic bar codes, record the order of every two field picture, every frame bar code image is decoded, according to the frame data order of record, data are carried out to assembled and data check, reduction and recovery initial data.
Have the following advantages specifically:
Expand exchanges data capacity:
By automatic analysis and judgement data type and capacity, generate corresponding dynamic electron bar code, expand data capacity, bar code by scanning the other side can realize obtaining of data and synchronous, alleviated user's operating procedure, expanded the scope of application of exchanges data, can carry larger file, as video etc., images etc., have improved user's experience.
Reduce costs:
Compare the universal high with price of short-distance wireless technology, as NFC technology, by contrast, high-resolution camera is universal in terminal large area, barcode technology is also very ripe, by the mode of photoelectricity, reduced significantly the software and hardware requirement of terminal, reduced the input cost of user in terminal.
