Problems solved by technology

The most commonly used Bluetooth exchange technology in the existing short-distance information exchange technology, two user terminals need to perform a series of operations such as Bluetooth pairing on the two user terminals that share information before transmitting information, which is relatively cumbersome, especially For the transmission of some short messages, for example, sharing and transmitting a contact information, a wireless local area network (WIFI) password, an identification code, an order information, etc., the time required for a series of operations such as Bluetooth pairing is much longer than the information transmission itself. time required, resulting in inefficient information exchange

Abstract

Embodiments of the invention disclose a short-distance information exchange method and system, an information sending device, an information receiving device and a terminal. The method comprises the following steps: receiving an information sending request, wherein the information sending request comprises information to be transmitted; carrying out coding on the information to be transmitted, and converting the information to be transmitted into a Morse code digital signal comprising Morse numbers and / or Morse letters; carrying out D / A conversion on the Morse code digital signal according to a Morse code encoding table to enable the Morse code digital signal to be converted into a Morse code sequence, and adding a character interval between two adjacent Morse codes to obtain a Morse code analog signal, wherein the Morse code sequence comprises more than one Morse codes arranged in sequence; and sending the Morse code analog signal in a Morse electric wave sound manner. Therefore, tedious and complex operation of carrying out pairing between user terminals sharing the information can be reduced, information transmission time is reduced, and information exchange efficiency is improved.

Description

technical field [0001] The invention relates to communication technology, in particular to a short-distance information exchange method and system, information sending and receiving equipment, and a terminal. Background technique [0002] At present, with the rapid development of communication technology and the popularization of user terminals, users often need to share information between user terminals. Currently, a user can send information on a user terminal to other user terminals that need to share the information through a mobile communication network. In addition, information can also be transmitted between user terminals through a short-distance information exchange technology, so as to realize sharing of the information among user terminals. [0003] Short-distance information exchange generally refers to information exchange within 5 meters. The most commonly used Bluetooth exchange technology in the existing short-distance information exchange technology, two ...
