Embodiment 1

[0070] Such as figure 1 As shown, it is a schematic flow chart of the data transmission method of the embodiment of the present invention, including:

[0071] Step S100: The sending end device encodes the data to be transmitted to generate N frames of first encoded data suitable for displaying as graphics, and each frame of first encoded data includes its corresponding serial number. Where N is a positive integer.

[0072] Coding in this embodiment and other embodiments of the present invention refers to a coding technology in which coded data is suitable for displaying graphics, and the most common ones are one-dimensional code coding technology and two-dimensional code coding technology. One-dimensional codes and two-dimensional codes were first invented in Japan. They use certain geometric figures to record data symbol information in black and white graphics that are distributed on a plane according to certain rules. The basic concepts of "0" and "1" bit streams use sever...

Embodiment 2

[0097] This embodiment provides a data transmission system such as Figure 4 As shown, it includes: a sending end device 10 and a receiving end device 20 . The sending end device 10 includes: a first encoding unit 101, configured to encode the data to be transmitted to generate N frames of first encoded data suitable for display as graphics, and each frame of first encoded data contains its corresponding pipeline number, N is a positive integer; the first display unit 102 is configured to continuously display each frame of first encoded data generated by the first encoding unit 101 . The receiver device 20 includes: a first collection unit 201, configured to continuously collect the first coded data displayed by the first display unit 102; an extraction unit 202, used to collect each Extracting the corresponding serial number from the first encoded data of one frame; the first decoding unit 203 is used for when all the serial numbers extracted by the extraction unit 202 are c...

Abstract

Provided are a data transmission method and system, sending end equipment and receiving end equipment. The data transmission method comprises the steps that the sending end equipment codes data to be transmitted, N frames of first coding data suitable for being displayed as images are generated, each frame of the first coding data comprises corresponding serial numbers, and N is a positive integer; all frames of the first coding data are continuously displayed by the sending end equipment; the receiving end equipment continuously collects the first coding data displayed by the sending end equipment and extracts the corresponding serial numbers from all frames of the first coding data; if all the extracted serial numbers are continuous, the receiving end equipment carries out decoding on the collected first coding data, and the data are obtained. According to the technical scheme, the data transmission method has the advantages of being low in cost and high in generality and safety.

Description

technical field [0001] The present invention relates to the technical field of data transmission, in particular to a data transmission method and system, a sending end device and a receiving end device. Background technique [0002] With the rapid development of communication technology, a variety of methods for data transmission between devices have emerged, such as Bluetooth technology that supports short-distance transmission, Wifi (Wireless Fidelity) and near field communication (NFC, Near Field Communication) technology, And mobile communication technology, microwave communication technology, etc. that support long-distance transmission. Among them, the communication technology supporting short-distance transmission is being more and more widely used because of its more flexible and more reliable transmission. For example, data transmission can be performed between mobile terminals installed with Bluetooth transceiver devices. [0003] But these near-field communicati...
