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...
