Embodiment Construction

[0014] This embodiment provides a method for information exchange between short-distance devices. Two devices respectively having a microphone and a speaker module can communicate information through sound within a relatively short distance. This is accomplished by sending a special audio stream from the speaker on one side, and receiving and interpreting it from the microphone on the other side. When the receiver is in the monitoring state, the sender performs audio encoding on the information to be sent, which is specifically manifested as some spectrum patterns (Pattern) with a limited duration on the spectrum, and adds head and tail marks for synchronization to the audio stream if necessary. The sound is then played from the speaker. As far as the receiver is concerned, it has been listening to the data received by the microphone, and once it detects the sync header mark, it starts to analyze the audio and extract interesting information from it.

Abstract

The invention discloses a wireless information transmitting method which is used for transmitting information in a short distance. The wireless information transmitting method comprises the steps of: defining all information units to be in different frequency spectrum modes; transmitting the information as follows: encoding the information to be transmitted into specific frequency spectrum mode signals according to the information units, and transmitting the signals after the signals are converted into sound; and receiving the information as follows: receiving the frequency spectrum mode signals from the air by a microphone, and then decoding the frequency spectrum into the original information.

Description

technical field [0001] The invention relates to a wireless information transmission method, in particular to a short-distance wireless information transmission method. Background technique [0002] At present, there are many methods for short-distance wireless information transmission between two devices (such as mobile phones or robots), such as Wifi technology, Bluetooth technology, and infrared transmission technology. Due to its directional limitation, infrared transmission technology has many inconveniences in application; while Wi-Fi technology and Bluetooth technology are relatively mature, but require independent chip modules and radio frequency modules, which are costly and complicated. [0003] The main way of communication between people is through language, and when the distance is not too far, information is exchanged through conversation. Speech recognition is a technology invented by people to enable devices to understand human speech, but human speech is gra...
