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]The embodiments of the present invention relate to the technical field of terminals, and in particular to a communication method and communication device.Background technique[0002]With the development of terminal technology, the various functions of the terminal make the terminal used by the user longer and longer, which leads to an increase in the number of times the terminal is charged. Therefore, the safety of charging is becoming more and more important.[0003]Generally, unplugging the charging cable during high-current fast charging of the terminal may cause an arc phenomenon. The spark generated by the arc phenomenon may cause damage to the terminal or the charger interface and threaten the personal safety of the user. Taking the charging cable as a Universal Serial Bus (USB) cable as an example, the current charging protection mechanism is mainly: the terminal detects whether the data pin in the USB cable and the data pin in the USB charging hole on the te...
