The invention relates to the communication filed, and discloses two-dimensional code transmission and reception methods and transmission and reception devices. The transmission device encodes the information to be transmitted in an encoding rule of two-dimensional codes and generates the two-dimensional code information expressed by a binary system data flow; and after the generated two-dimensional code information is converted into audio information, the audio information is transmitted to a reception end, so that the two-dimensional code information can be transmitted to the reception end in a manner of audio information, and the aim of information transmission is achieved. After the reception device receives the audio information from a transmission end, the audio information is analyzed based on an agreed frequency to obtain the two-dimensional code information expressed by the binary system data flow, the two-dimensional code information is decoded based on the encoding rule of the two-dimensional codes, so that the reception device can obtain the information transmitted by the audio information. In this way, the transmission device transmits the two-dimensional code information in a manner of audio information to enable the reception device to improve the success rate and efficiency in obtaining the two-dimensional code information.
Description
technical field [0001] The invention relates to the communication field, in particular to a method for sending and receiving two-dimensional code information and a sending and receiving device. Background technique [0002] Two-dimensional code information is a readable barcode developed on the basis of one-dimensional barcodes. It is a black and white pattern distributed on a plane (two-dimensional direction) with a certain geometric figure according to certain rules. To record data symbol information, because it has the advantages of large information capacity, beyond the limitation of letters and numbers, and strong resistance to damage, it is now more and more widely used. [0003] In daily life, equipment (such as mobile phones) can obtain the information contained in it by scanning the two-dimensional code information and identifying the binary data recorded in the length and width of the barcode. However, in some cases, if the image of the two-dimensional code inform...
