Code mapping-based data transmission method

The invention relates to a code mapping-based data transmission method. The method includes the following steps that: an equipment host demonstrates a code mapping on site or directly transmits the code mapping to a terminal; the terminal performs pattern recognition on the received code mapping through a recognition module; the terminal completes decoding through a code decoding module so as to obtain a status instruction or control instruction; and the terminal displays the status instruction or executes the control instruction. With the code mapping-based data transmission method adopted, communication information channel codes can be subjected to hardware carrier modulation and then are sent out, so as to be transmitted in a short-time burst manner; communication path optimization can be realized, and a pattern recognition system of the terminal, routing and host can be adaptive to an optimal path, and repeat communication of other paths can be reduced.
