Abstract

The embodiment of the invention provides a communication method and a communication device in order to solve a problem of an arc phenomenon generated when a charging line is pulled out. The communication method comprises the steps of obtaining the transmission time length of a target message to be transmitted, wherein the target message includes data transmitted when a charging device charges a terminal; if the transmission time length is greater than or equal to a preset time length, dividing the target message into M data blocks, wherein the transmission time length of each data block in theM data blocks is less than the preset time length, and M is a positive integer; and sequentially transmitting the data blocks according to a target time interval.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of terminals, and in particular, to a communication method and a communication device. Background technique [0002] With the development of terminal technology, various functions of the terminal make the terminal be used by users for a longer and longer time, which leads to more charging times of the terminal. Therefore, the safety of charging is also becoming more and more important. [0003] Usually, pulling out the charging cable when the terminal is performing high-current fast charging may cause an arc phenomenon, and the sparks generated by the arc phenomenon may cause damage to the terminal or the interface of the charger, and threaten the personal safety of the user. Taking the charging line as a Universal Serial Bus (USB) line as an example, the current charging protection mechanism is mainly: the terminal detects whether the data pin in the USB line and the data pin in the US...
