Abstract

The invention discloses a data transmission method and system. The data transmission method comprises the steps that first equipment sends audio information of a set frequency band; second equipment receives the audio information sent by the first equipment; the second equipment processes the received audio information and obtains the frequency spectrum of the audio information; the second equipment converts the obtained audio information spectrum into set data according to a set first conversion rule; and the second equipment identifies the setting information according to the converted data and a second conversion rule. According to the data transmission method and system provided by the invention, the data can be transmitted in an audio mode without a network or other existing communication modes, the security is high, and meanwhile, the cost can be reduced. According to the invention, short-distance communication can be completed by using audio transmission data, and the method only depends on a microphone and has low requirements on the environment.

Description

technical field [0001] The invention belongs to the technical field of electronic communication and relates to a communication system, in particular to a data transmission method and system. Background technique [0002] At present, short-distance wireless communication is mainly through devices such as hotspots and Bluetooth, and communication cannot be completed in an environment without a network and Bluetooth. [0003] In view of this, there is an urgent need to design a new data communication method so as to overcome at least some of the above-mentioned defects existing in the existing data communication method. Contents of the invention [0004] The invention provides a data transmission method and system, which can transmit data through audio without network and other existing communication methods, with high security and reduced cost. [0005] In order to solve the above technical problems, according to one aspect of the present invention, the following technical ...
