Abstract

The embodiment of the invention discloses a data transmission circuit and method. The data transmission circuit comprises a data sending circuit and a data receiving circuit, wherein the data sendingcircuit is coupled with the data receiving circuit; the data sending circuit is used for determining a target rectangular wave parameter corresponding to target data according to a corresponding relation between the data and the rectangular wave parameter under the condition that a data sending instruction is received, and sending a rectangular wave matched with the target rectangular wave parameter to the data receiving circuit; and the data sending instruction comprises the target data; and the data receiving circuit is used for receiving the rectangular wave, determining the target rectangular wave parameter according to the rectangular wave, and determining the target data according to the corresponding relationship between the data and the rectangular wave parameter. According to theembodiment of the invention, the data can be sent to the data receiving circuit in a rectangular wave mode through the data sending circuit, and the circuit structure is simplified, and the stabilityand reliability of the whole device are improved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a data transmission circuit and method. Background technique [0002] With the improvement of people's daily life, household appliances such as vacuum cleaners, electric fans, and hair dryers have become necessities in people's lives.
